KSEA LETTERS Vol. 40 No. 4 June 20124

Building upon former Presidents’ accomplishments, we are 4,344 members strong which repre-sents more than 30% increase over the previous year. Our budget also increased by more than 20%. We have provided more career enhancing benefits to our members to help them profession-ally in both America and Korea. We are a premier technical society respected by all scientists and engineers that will continue to exist to help its members succeed in the main stream of America.

As the 40th President, I am proud of achievements that directors and the staff have made together for KSEA as noted. However, as a senior faculty member who endeavors to develop careers of ap-prentices, I cannot help but to be excited about all the accomplishments that directors have made for their own personal and professional lives during the 40th administrative term while tirelessly serving the KSEA. I believe that directors must serve the KSEA not only for the administrative duties, but also as role models for its members at various stages of their career and personal lives. Here are several noteworthy accomplishments by the directors that I will remember and cherish.

• Executive Director Yongho Sohn received 2012 UCF Research Incentive Award.• Finance Director Seri Park became an endowed Clare Booth Luce Assistant Professor at Villanova University. • Headquarter Office Director Kyungjae Myung’s received the NIH Director’s Challenge Grant and became an editorial board member of Genome Integrity and Journal of Genomics.• Membership Director 2 Hanseup Kim received both the DARPA Young Faculty Award and the NSF CAREER Award. • Membership Director 3 Jungah Jung was married on December 18, 2011 and is now expecting a baby. • YG Director 1 Byungdo Kim has become the Director of High Performance Computing Center in Advanced Research Com puting at Virginia Institute of Technology.• YG Director 2 Sun Min Israel Jung became a member of the Executive Development Institute for emerging Asian industry leaders and the President of the Boeing Asian American Professionals Association. • Publication Director 2 Hyunggun Kim received an R01 grant award from the NIH and became a father on December 15, 2011.• Publication Director 3 Jae Yu received the Dean’s outstanding research award at University of Texas at Dallas.

I would like to end my statement by quoting words from Dr. Jim Gates, Advisor to KSEA and a member of President Obama’s Council of Advisors on Science and Technology (PCAST), “The development of world-recognized iconic products and processes will rely on communities similar to KSEA community that are able to create an environment where the cultural uniqueness of societies and individuals can be welded to the rigor and demands of science and engineering.”

It has been my honor to serve you all.…

president of Ksea visits director of bigheart[Charles Lee (Alumnus, UC Berkeley KSEA Chapter, Computer Programmer, Luvocracy Inc.) &

Ann Yun (President of UC Berkeley KSEA Chapter)]

On a bright Sunday morning, I met President Hosin Lee in San Francisco and we took the BART to Berkeley together. I have known him for over 26 years but this was the first time he asked for my help. I asked Ann Yun, President of YG Chapter at UC Berkeley, to help me document KSEA President Lee’s interview with Prof. Luke Lee (Prof. Lee), Director of BIGHEART Center at UC Berkeley.

Prof. Lee began by telling us about the Petri dish, invented over a hundred years ago, that has remained essentially unchanged since its inception. In order to perform more accurate experiments faster in a natural condition for culturing, Prof. Lee has devel-oped a way to combine a thousand Petri dishes into one chip. When Prof. Lee was younger, he was busy protecting his ideas – now he says he knows better, “Embrace

people and share your ideas,” he explains, “Even if you lose at the beginning, at the end you’ll win.” Why, you may ask? “If you believe you are creative you’ll create another idea. The later ideas are better anyway.”

Prof. Lee advises young people to enjoy what they do, but also to speak their own minds. “Don’t be shy. I used to be shy,” he says. His current research questions the fundamental biological principles such as mRNA transcription that have been accepted for decades – but while accepted, have never been proven, especially not by one as perspicacious as Prof. Lee.

As he scurried to make sure to hold doors open for us as we walked through his labs, Prof. Lee was remarkably open about his past challenges and failures. His personal philosophy is to be open about failure – hiding failure only makes it harder to learn and grow, he says. He also emphasized that researchers should think about social impact with their research. He currently develops a standalone system to make a cheap and effective blood testing device to quickly detect HIV, tuberculosis and malaria, sponsored by the Bill Gates Foundation, which has the power to affect hundreds of thousands of lives. President Lee was particularly impressed with Prof. Lee’s high ethical standard such as being selective in receiv-ing research funds from corporate sponsors and not using embryonic cell for his research.

After the dinner with local KSEA YG members, Prof. Lee offered to give us a ride to San Francisco using his car. That was the best part of the interview where President Lee was so excited and took a picture of Prof. Lee in his car, exclaiming, “1990 Toyota Corolla with all manual!” I knew why President Lee was so excited since I know he drives 1999 Chevy Tracker with all manual including door locks and windows. President Lee did not hesitate to ask him why he drove such an old car. Prof. Lee answered, “I have better things for the money.” President Lee nodded with a big satisfied smile. After dropping off President Lee at the hotel, he gave me a ride to my office on Sunday night and, then, I have realized why his center was named as BIGHEART.


exploration of cellUlar galaxY: search for the inner life of the cell[Luke P. Lee]

Arnold and Barbara Silverman Distinguished Professor, Bioengineering UC Berkeley

Humankind has always been fascinated with space exploration and reaching up to the stars. Scientific discovery and breakthroughs in technology allow us to explore space outside our solar system. Now we are learning how to explore inner life of living cells. By creating biologically inspired optics1-based 3D microscopes and innovative nanocrescent antennae2-based satellite nanoscopes, we can enjoy exploring cellular space of living cells and obtain snapshots of what we metaphorically refer to as the cellular galaxy. Satel-lite nanoscopes can also be used to produce desired changes in proteins and genes.

Satellite nanoscopes are tiny optical antennae integrated with target finder, light sources and optical gene switches. They use a phenomenon known as ‘nanoplasmonics’, which involves the interactions of photon and electron on the surface of metals. These nanoscopes can be placed within living cells or in the space between cells. Nanoscopes with multiple functions (i.e. precise targeting, imaging, gene delivery, and gene regulations) will generate new fundamental knowledge in basic biological science as well as advanc-ing the new field of translational medicine. Despite our understanding of cells as the basic building blocks of life, little is known about the dynamics of their intracellular processes and extracellular communication. The information transferred by signaling molecules depends not only upon their biochemical composition but also upon their spatio-temporal distributions in living cells. It is thus important to measure how the signaling molecules are transmitting their signals within cells as well as between cells, and to obtain ultrafast detection of biomolecule release and of growth factors administrated during different stages of tissue development. Yet, doing this is still a major challenge. To address this challenge, we have been developing nanosatellites for real-time monitoring of dynamic cellular activities in living cells. We will describe three ways in which nanosatellites can be of use: (a) imaging cellular activities3, (b) regulating and sensing gene expression, and (c) creating transcriptional pulses.

real-tiMe nanoscale MolecUlar iMaging of cellUlar activities Our understanding of biological systems is increasingly dependent on our ability to visualize and measure biomolecules and bio-logical events with high spatial and temporal resolution within living cells. Novel cellular and molecular imaging techniques are essential to the advancement of basic life science and translational medicine. The challenge is to develop techniques to noninvasively capture cellular information and resolve dynamic intracellular processes. In response to this challenge we developed satellite nano-scopes capable of specific molecular-level targeting, imaging, and intervention (fig.1).

These nanoscopes will enable high-resolution monitoring of the dynamics of proteins, enzymes, and subcellular or-ganelles without causing dam-age or exogenous artifacts that affect cell function. Current techniques require fluorescent labeling, which has limita-tions and cannot provide the dynamics of molecular finger-print changes. The electron microscope (EM) can resolve subcellular structures without

labeling, but EM irreversibly damages living cells. Moreover, EM and fluorescence imaging cannot provide spectroscopic data (i.e. chemical fingerprints). Our recent accomplishments offer striking advantages over traditional imaging techniques: stability, bio-compatibility, selectivity, and potential for spectroscopic imaging of electronic states of biomolecules in living cells.3

By utilizing satellite nanoscopes, we can obtain snapshots of what we metaphorically refer to as the cellular galaxy. Using optical antennas with specific resonant wavelengths within living cells as well as in the space between cells, we can measure localized bio-chemical features (i.e. structural and kinetic features) by spectroscopic imaging.3 Also, since interactions between nucleic acids and proteins are essential to genetic information processing, the detection of size changes in nucleic acids is the key to mapping. Our nanoplasmonic molecular ruler with subnanometer axial resolution allows for a label-free, quantitative, real-time measurement

of nuclease activity and also serves as a new DNA footprint-ing platform, which can accurately detect and map the specific binding of a protein to DNA.4 The nanoplasmonic optical an-tenna function as “nanosatellites”, exploratory devices in the living cellular environment for selective targeting, sensing, and gene regulations. Remote controls of localized optical gene de-livery5 and the generation of transcriptional pulses via satellite nanoscopes allows spatio-temporal control of gene regulations on demand and precision molecular level optogenetics for sys-tems biologists and clinicians, while the local dynamic response of chemicals of interest can be investigated with the spectro-scopic sensing functionality.

satellite nanoscopes as reMote optical sWitches for gene, protein regUlations & sensing After performing optical gene regulation5 in living cells by sat-ellite nanoscopes (fig. 2), we can utilize them to capture the images of electron transfer dynamics of some key enzymes. Precise remote control of optical gene regulation and protein expression in living cells is a powerful tool for studying cellular signaling pathways and systems biology. To advance the studies of intracellular & extracellular signaling pathways, we have assembled nanoscale transmitter and receiver systems for remote manipulation of biological systems. Because of their large surface-to-volume ratio, nanoplasmonic gene or protein switches are ideal carriers of oligonucleotides (short nucleic acid sequences). Proteins can also be attached to these optical switches, and we can liberate them at a specific time in order to control the effects of intracellular and extracellular signaling molecules. While attached to their carriers, oligonucleotides are inactive. In the presence of NIR incident light that is matched to the resonance wavelength of gene carrier (i.e. optical antenna of nanosatellite), the formerly bound substance is released, to freely interact with the local environment. Using such gene switches, intracellular genes can be silenced on-demand. Similar methods will be used for the precision delivery of peptides and protein drugs in the extracellular space. Satellite nanoscopes can deliver both extracel-lular and intracellular signaling molecules for the systematic studies of living cells.

creating transcriptional pUlses in living cells Transcription of genes, by which the genetic code written in DNA is transformed into the mobile RNA message, is commonly thought to be a more or less continuous process. However, it can occur in “bursts” or “pulses” within cells depend on the influ-ence of many other factors. Using satellite nanoscopes we will create transcriptional pulses in living cells and understand the mechanism of living systems. Since transcriptional dynamics play important roles in developmental processes, stem cell speciali-zation and cancer progression, precise transcriptional control can provide unparalleled insight into these processes. Using NIR illumination as a remote optical trigger to release free oligonucleotides and ‘activate’ their functionality, repressor and activator genes are silenced on-demand. Creation of transcriptional pulses using satellite nanoscopes lays the foundation for enabling the generation and elucidation of regulated transcriptional dynamics governing normal developmental processes as well as unregu-lated transcriptional dynamics responsible for disease. These multifunctional nanosatellites with targeting, sensing, optical gene switching capability will allow us to study living systems systematically.

In summary, the possibility to use the satellite nanoscopes as light sources, transmitters, and carriers for oligonucleotides, which can be released in response to an optical pulse at a specific wavelength, is exciting and promising. This approach holds enormous power to regulate gene expression in a way that has not been previously possible, such as in the form of “transcriptional pulses” that can switch cellular signaling pathways on or off. The ability to target, sense, modify and control cellular function will have vast implications beyond our imagination.

seqUencing the cancer genoMe[Peter J. Park]

Associate Professor, Computational GenomicsHarvard Medical School

The technological advances in DNA sequencing—determining the sequence of nucleotides (A, C, G, or T) that comprise a stretch of DNA—in the past few years have been breathtaking. To sequence the genome of an organism, one typically takes a population of cells, breaks the membrane to obtain the DNA, fractures the DNA into small fragments, prepares them for sequencing, and a sequencer car-ries out specific enzymatic reactions to determine the nucleotide sequences for each fragment. Then, a computational method is used to put the pieces back together into a single long stretch. The perfect machine would sequence a large stretch of DNA (~108 nucleotides for a human chromosome) very quickly. The ‘old’ standard technology can sequence about 103 nucleotides in a row, one fragment at a time. The new technology—often referred to as ‘next-generation sequencing’—can sequence shorter fragments of about 102 nucleotides but more than a billion of fragments at a time. See figure 1 for a popular DNA sequencer from Illumina, Inc. This massively parallel approach has been made possible by a convergence of several technologies, including high-resolution microscopy, miniaturization, and new chemistry for amplification of DNA and labeling and detection of nucleotides. As a result, the cost of sequencing has plunged: the original sequencing of the human genome, completed in 2003, cost of $3 billion dollars; it cost several million dollars just five years ago; and now a human genome can be sequenced, albeit at a lower quality than the original version, for less than $5,000. Many people expect this to be around $1,000 in a few years. Although we focus on the sequencing of individual human genomes below, this technology also has numerous applications in basic biomedical research.

This ‘whole-genome sequencing’ (sequencing of the entire genome rather than, e.g., a small set of genes) generates a massive amount of data. A high-quality human genome is approximately ~300 gigabytes, after reducing from a much larger form of raw data. Several projects in my laboratory involve on the order of 100 genomes, which totals about 30 terabytes (TB). Even the basic manipulations are far from trivial for data sets of this size. To move the data over the internet, for instance, a special transfer protocol is often set up, as http or ftp connections tend to fail; in some cases, mailing a hard drive turns out to be a faster option. Storing the data on high-performance disks is also costly. The National Institutes of Health (NIH), which funds the vast majority of biomedical research, has been providing an archive to which all data from published papers were to be deposited; however, it is unable to keep up with the terabytes of sequenc-ing data that are being generated per day and has recently announced that it plans to discontinue one of their major databases called Sequencing Read Archive. At a recent gathering of experts to provide guidance to NIH, we estimated that there would be at least 30 petabytes (1 petabyte = 1,000 terabytes = 1,000,000 gigabytes) of sequencing data in the next couple of years.

Analysis of these data presents a multitude of serious challenges. To give an example, a first step in analysis is genome ‘alignment’, in which every short sequences (e.g., TGAGC…GCGTG) is compared to the ‘reference genome’ sequence to identify the location(s) that most closely match the given sequence. This string-match process, with the possibility of gaps of unknown size, can be done blazingly fast for a single sequence by one of several algorithms available. But repeating this process more than 100 billion times, as required in some of our work, requires specialized algorithms and significant computing power, typically hundreds or thousands of compute com-puting nodes. High-performance computing has long been a domain of physical sciences, but biological sciences are proving to be the next frontier in computational research.

One area of interest for my laboratory is a detailed characterization of the cancer genome and what it might tell us about the initiation and progression of the disease. Despite decades of research, there has been little improvement in treatment of many tumors: for the most aggressive form of brain tumor (glioblastoma), for instance, the median survival rate remains essentially the same as it was thirty years ago. Given that most approaches have failed to yield significant progress, the hope is that sequencing the genome of those brain tumor cells will give us some insights, especially in relation to other clinical data of the patients. There is now a major effort by the NIH called The Cancer Genome Atlas, in which 500 patients for each of the 20 tumors chosen are being characterized. This includes profiling of several aspects of the tumor cells such as the activity level of every gene, as well as whole-genome sequencing for an increasingly large fraction of the patients. There is also an international effort called International Cancer Genome Consortium, which involves more than a dozen countries with each profiling a particular tumor type. Through our involvement in these consortium projects, we have learned a great deal about cancer genomics. One of the distinguishing characteristics of the cancer genomes is the presence of structural rear-rangements, e.g., segment of one chromosome being fused with another to produce an altered form of a protein. By developing new strategies for identifying these genomic alterations in the cancer genome, we will be able to better understand the ‘driver’ events that impact tumorigenesis.

The era of widespread genome sequencing has begun, although our ability to understand the data is in its infancy. The new mantra in the field now is ‘A $1,000 genome, $1 million analysis’, referring to the fact that while the sequencing of the genome is getting less expensive every year, assembling a team of experts to analyze and interpret the genome is more costly. One thing we do know about the human genome is that it is far more complex than we have imagined, and that a phenotype—e.g., why one gets cancer or diabe-tes—is a complex interaction of genetic and environmental factors that we may not be able to disentangle for years to come. This is well demonstrated by the fact that we still don’t know the precise genetic underpinning for one of the traits that are most clearly genetic in nature—one’s height—after many years of intense research.

The ultimate application of this technology is its use in the clinic: a physician would prescribe sequencing of the patient genome, and information from his genome would be used to guide the treatment of the patient. For patients with family history, sequencing of the genome can be tremendously helpful, as there are already drugs such as Iressa and Gleevec that are effective only for patient with cer-tain mutations in their genome. Healthy individuals could also get their genome sequenced to better understand their predisposition to various diseases, although distinguishing the key disease-related variants from a sea of features will be difficult for the immediate future. For the short term, analysis of a genome will lead to a large number of false positive findings. But, as platforms and algorithms are further developed and more data are accumulated, this high-throughput sequencing technology will have profound impact both in advancing basic sciences and in applications to patient care.

a qUest for the origin of the Universe[Jaehoon Yu]

Professor, PhysicsUniversity of Texas at Arlington

Whenever we step out to the backyard and look up the sky, we are touched by the beauty of the universe and wonder how the beau-tiful universe works, what make it up, what rules it follow, and ultimately where we all come from. The quest for answers to these fundamental questions begins with looking into the smallest possible distance scales human can probe. One of the most fundamen-tal properties of the fundamental particle is the fact that they cannot be broken into any smaller pieces. The field of particle physics looks for these fundamental building blocks of the universe and seeks to understand the forces between them to better our and our next generations’ lives.

Experimental part of the field uses powerful particle accelerators and massive detectors to accomplish the above goals. The ever-smaller distance scale needed to look deeper into the matter requires ever-higher energy accelerators, and the energetic particles emerging from the interactions of accelerated particles require large detectors. Theories must provide comprehensive models with precise predictions. They have been successful in describing observed phenomena and unifying two of the four known fundamental forces – electromagnetic force and the weak nuclear force – into one. The progress of these theoretical understanding resulted in the

Standard Model (SM) [1] of particle physics which presents a simple but an elegant picture of the fundamental particles and forces.

In SM, all visible matters in the universe consists of six quarks, six leptons (parti-cles with small mass), 12 force carriers (there are 2 W bosons and 8 gluons) and one electrically neutral particle called the Higgs particle that is a manifestation of a mechanism that gives mass to all fundamental particles. Predictions of SM have been successfully confirmed by precision measurements for the past few decades. The model is incomplete, however, in the sense that there still remain numerous outstanding and fundamental questions; such as what is the origin of mass, why is there matter- anti matter asymmetry, what are dark matter and dark energy that make up 96% of the universe and what new physics lie beyond the SM? One of the key missing elements is the Higgs particle whose mass is not predicted in SM, making the search for the particle much more challenging since searches must be done in a wide range of mass and eliminate them. It also is acknowledged that, from the theoretical standpoint, SM must be part of a larger theory (“beyond” the SM or BSM), which is yet to be experimentally confirmed.

In mid March 2010, the new particle accelerator, the Large Hadron Collider (LHC)[2] at the European Organization for Nuclear Research (CERN) [3] in Geneva, Switzerland started colliding protons at the energy of 7 Tera electron Volts (TeV), the highest energy humans ever accomplished. The two large general-purpose particle physics detectors, ATLAS (A Toroi-dal LHC ApparatuS) [4], shown in a photo in Figure 2, and CMS (Compact Muon Solenoid) [5], together with three other experiments started taking data from the collisions. The LHC and the detectors have been operating superbly and have ac-cumulated large amount of data in 2011 and presented results in Higgs searches.

As the ratio of the measured production probability with respect to the SM pre-dictions Figure 3 shows, the combination of both the experiment shows over a 3.1 standard deviation signature of the Higgs particle at the mass of 126GeV. Any values of the mass below the line at the ratio of 1 have been eliminated, leaving only very little sliver of mass range. The 3.1 standard deviation excess at the mass of 126GeV corresponds to a confidence level of 99.7% for having observed the real Higgs particle. While this confidence level is quite high in everyday standards, it is still insufficient to claim a definitive discovery of the Higgs particle since the canonical significance of a discovery is over 5 standard deviations, the confidence level of 99.99994%.

In 2012, the LHC increased its energy to 8TeV, and the experiments have been taking data since late March. The amount of data expected through 2012 will quadruple the amount of data collected in 2011, increasing statistical significance by a factor of two. This will allow the LHC experiments to either definitively dis-cover the Higgs particle or definitively eliminate the existence of it. The discovery will open a new era of another powerful particle accelerator, the linear electron-positron collider, to investigate the property of the discovered particle precisely while the definitive elimination of the Higgs particle will require a whole new theory of physics to describe the universe and its origin.

As part of understanding the fundamental principle of the universe, many particle physics experiments are looking for incontrovertible evi-dence for new physics while the search for the Higgs particle is under-going. One of the most popular suggestions for the new theory is Su-persymmetry (SUSY) [6] which introduces a new symmetry between fundamental particles. SUSY signals are of particular interest, as they provide a natural explanation for the “dark matter”, known to make up 23% of our universe, and help us to understand the fundamental connection between particle physics and cosmology. An example of a new experiment [7] is an ultra sensitive measurement of a particular particle, called a K-particle or Kaons, at the particle accelerator facility in the US’ Fermi National Accelerator Laboratory (Fermilab)[8] near Chicago. The precision measurement of Kaon’s decay probability to a particular final state (~10-11) with respect to SM prediction measured in the detector shown in Figure 4 can provide a definitive evidence of paradigm changing new fundamental physics.

In a quest for the original of the universe, particle physics uses powerful accelerators and large detectors to capture the most illusive particle thus far and to seek new physics that might yet to be discovered. The year 2012 will likely be the year the Higgs particle is found or is completely eliminated, which would stimulate more vigorous searches for new physics. Korea has been playing a sig-nificant role in this field and will continue to do so in the future, leveraging the resources and infrastructures accumulated through the Rare Isotope Science Project (RISP) [9]. Korea’s participation to an experiment like the ultra precision Kaon measurement above will put Korea at the front line in searching for paradigm changing new physics and become a strong leader and a meaningful partner to the world in a quest for the origin of the universe. references[1] S.L.Glashow and S.

neUroiMaging to visUalize White Matter fiber connections in the brain[Jongho Lee]

Assistant Professor, RadiologyPerelman School of Medicine, University of Pennsylvania2012 KSEA Young Investigator Grant ($10,000) Recipient

Over the last two decades, neuroimaging has become a powerful tool to study human brain. Various MRI acquisition methods and data processing techniques such as high-resolution structural imaging (basic anatomical information), voxel-based morphometry (structural variation among subjects), functional MRI (task-based brain activity), resting-state fMRI (spontaneous brain activity), diffusion tensor imaging (fiber orientation mapping in white matter) and tracktography (DTI-based fiber connections) have been developed to help us understand how the brain is structured, wired and function. However, the limitations in the achievable resolu-tion which is on the order of sub-mm3 in structural images and several mm3 in fMRI and DTI have become a major challenge. This has led us to pursue new MRI contrast mechanisms and develop higher performance MRI systems. In this article, I summarized my efforts to develop a new method to improve the resolution of fiber orientation maps.

Identifying white matter fiber connections has over a hundred years’ history. Techniques such as gross dissection, myelin staining, double silver staining, Nauta staining, and autoradiography have been developed and provided fiber connection information in histological slices. However, reconstructing 3-dimensional fiber tracts from these data is extremely challenging. The visualization of 3D whole brain white matter connections has become plausible with diffusion tensor imaging (DTI, ref. [1]) which measures relative dif-fusivity of water molecules in fiber bundles using MRI. Unfortunately, this method suffers from a limited resolution and associated partial volume effects. In conventional resolution (8 mm3), more than 1/3 of the voxels have been suggested to have multiple fiber orientations and the orientations in these voxels are thus incorrectly assigned. As a result, the method is limited to identify only large fiber pathways. One way to resolve complex white matter orientation is to achieve in sub-millimeter resolution (~ 0.1 mm) such that the partial volume ef-fects can be reduced. This is challenging in DTI to due to the limited contrast to noise ratio (CNR).

Over the last few years, my colleagues and I have investigated the properties of magnetic susceptibility in the brain at high magnetic field strengths. We have discovered the existence of susceptibility anisotropy in white matter (i.e., white matter magnetic susceptibility

is not a scalar but a tensor that is Bo orientation dependent) [2]. We also have demonstrated that R2* contrast, a magnetic susceptibility sensitive tissue transverse magnetization relaxa-tion rate, is Bo orientation dependent as a function of sin2θ and sin4θ which agrees well with the susceptibility anisotropy mod-el of white matter [3]. Based on this observation, we success-fully developed a novel fiber orientation mapping method from this R2* (R2*-based fiber orientation mapping) [3]. To obtain fiber orientation information, the orientation of white matter fibers needs to be changed relative to the main magnetic field of the MRI. The resulting images from multiple orientations are realigned together and decoded to extract fiber orientation information in each voxel.

One of the major advantages of this new method compared to DTI is SNR efficiency. A similar acquisition scheme to our approach has revealed details of human anatomy in 0.02 mm3 voxels in vivo and 0.0034 mm3 voxels in fixed brains. These resolutions are a few hundred times better than that of DTI and we expect to acquire a similar ultra-high resolution for the R2*-based fiber orientation mapping. Another advantage is that the method directly benefits from high field strength magnets that are currently available (7 Tesla available at UPENN and 11.7 Tesla at NIH) or in-planning (14 Tesla, Neuroscience Research Institute, Gachon university, Korea). The CNR is expected to increase supra-linearly with the field suggesting a factor of 3.5 times increase in CNR at 7 Tesla compared to 3 Tesla. The in-creased CNR can be traded to further increase the resolution. In DTI, however, much limited (or no) improvement at high field is expected due to the corresponding tissue relaxation (T2) decrease at high field.

With these advantages, the new fiber orientation mapping method may provide unprecedented resolution for studying white matter connections. Improved resolution will reveal unidentified white matter fiber tracts that are not visible with conventional DTI (e.g., mammillothalamic tract) and help separate white matter pathways that run closely together (e.g., stria terminalis and fornix). In the clinic, ultra-high resolution tractography may bring new insights into altered connectivity associated with dysplastic cortex, a major cause of focal epilepsy. Additionally, once an ultra-high resolution fiber connection template is available from fixed brain imaging, it will provide abundant a priori knowledge for in-vivo tractography.

In summary, the ultra-high resolution fiber connection map that will be generated by the newly developed R2*-based fiber orienta-tion mapping method will significantly improve our understanding of the brain connections.

ManY-bodY interactions in nanostrUctUres[Cheol-Hwan Park]Research Scientist

The Bosch Research and Technology Center2012 KSEA Young Investigator Grant ($10,000) Recipient

In a hydrogen atom, there is only one electron; by solving the Schrodinger’s equation, we can know everything about the electronic properties of hydrogen. In other atoms, molecules, or in solids, however, there are many electrons. In most practical cases, it is there-fore impossible to describe the interplay of so many electrons or extract useful information from them. Density-functional theory developed in mid 60’s [1,2] is a theory which enabled us to calculate ground-state properties – materials properties related to the elec-tronic ground state such as the equilibrium geometry, bulk modulus, and lattice vibration frequency. The essence of density-functional theory is that all we need to know for ground-state properties calculations is the charge density and not the complex many-electron wave function [1]. In condensed matter physics and materials sciences, density-functional theory is the most commonly used theoreti-cal tool for studying ground-state properties nowadays because of its accuracy and low computational cost.

On the other hand, density-functional theory fails severely in predicting or explaining ex-cited state properties of materi-als, simply because it is a theory only for ground states. How-ever, the subjects of all spectros-copy measurements are excited state properties. For example, the system being investigated is perturbed by injecting an elec-tron [fig. 1(a)] or a hole [fig. 1(b)], or by generating (through an incident photon or by other

means) an electron-hole pair [fig. 1(c)]. After this creation of an elementary excitation, all the other electrons, holes, and ions of the system participate in screening the external perturbation [fig. 1]. Thus, many-body interaction effects are very important in investigat-ing the excited state properties. Although density-functional calculations are normally performed using mean-field interactions (treat-ing other electrons by some mean-field potential), in order to describe excited state properties accurately, quite often, it is necessary to go beyond mean-field level of approxi-mations. I have been investigating the interactions between charge carriers, phonons, plasmons, and other elemen-tary excitations in solids and nanostruc-tures using many-body perturbation theory approaches [4,5], which is ar-guably the most practical and accurate method.

Many-body interaction effects are much more important in nanostructures than in bulk materials because there are not many charge carriers which can screen an external perturbation and also be-cause charge carriers cannot easily avoid each other. figure 2 illustrates that many-body interactions are extremely important in nanostructures.

(Right) Oi-na-moo bridge in Yeongju, Korea. (A photo from the web site of Munsu Myon in Yeongju Si.) People cannot help interacting with each other when crossing the bridge. Similarly, in nanostructures, charge carriers are interacting strongly among one another because it is not easy for them to avoid each other due to reduced dimensionality along one or more directions.

In figure 3, the absorbance spectrum of a bo-ron nitride nanotube obtained by considering electron-hole interactions is compared with that without considering these many-body in-teractions. It is clear that only when the inter-action between electrons and holes is consid-ered, the experimental results can be explained. It is noteworthy that the binding energy of ex-citons – onset energy shift upon turning on the excitonic effects – in boron nitride nanotubes (~2.3 eV) is significantly higher than the exci-ton binding energy in hexagonal boron nitride bulk structure (0.72 eV) [8].

figure 4 shows that the lifetime of charge carri-ers in graphene can be quantitatively explained if their interactions with other charge carriers

(including plasmons) and lattice vibrations (phonons) are properly taken into account. Lifetime of a charge carrier is directly related to its transport properties such as mean free path.

In summary, we have shown that many-body interactions are of crucial importance in understanding spectro-scopic properties of nanostructures. First-principles approaches based on density-functional theory and many-body perturbation theory can be suc-cessfully applied in investigating ther-mal and electrical conductivities, and optical and excitonic properties without using empirical parameters obtained from experimental results. Researches in this direction, therefore, have a broad implication in finding new sources of energy such as thermoelectric materials and solar cells.

Ksea ventUre challenge

New York UniversityWinner of the KSEA Business Venture Challenge at YGTLC 2012 ($10,000)

RF Test Labs is focused on developing and implementing innova-tive radio frequency (RF) emissions testing solutions. RF Test Labs employs novel, patent pending magnetic resonance (MR) technol-ogy developed at New York University (NYU) enabling state of the art testing of RF emitting devices such as cell phones, laptops, tab-lets, etc.

Thousands of wireless devices are brought to market annually. In-creased concerns about their RF-emissions safety have resulted in over $1 billion yearly expenditures on mandatory safety testing. Compared to existing procedures, RF Test Labs developed a faster, cheaper, and more versatile technology to provide RF-emissions testing services for device manufacturers.

Relying on the ability to utilize MRI technology for testing of RF emissions, RF Test Labs created a framework called the Magnetic Resonance RF Emissions Test (MR-RFET). MR-RFET is a novel alternative to existing SAR testing methods. This method is advan-tageous for quantifying RF emissions, as it is up to 20 times faster, cheaper, and can scan complex anatomical structures in higher 3D resolution. These advantages help reduce the lead-time associated

with device testing, thereby avoiding a testing bottleneck in the R&D process. Additionally, the method measures minute tempera-ture changes produced by RF emitting devices. This provides a more direct measure of health risks since temperature change is di-rectly correlated with tissue damage.

Speed, cost-efficiency, and versatilty are the differentiators that provide RF Test Labs with strategic advantage over competitors.

(1) Speed : Current SAR testing methods require on average 20 to 40 days to test a single smart phone. RF Test Labs’ proprietary technology can accelerate testing ~20 times, reducing the test duration to 1-3 days. Speed of testing is important for accelerat- ing product development cycles, lowering production costs for the electronic manufacturers.(2) Cost-efficiency : As the MR-RFET method is significantly faster, RF Test Labs’ operational costs are ~4 times lower compared to current testing methods. Pricing for this service will be 20% less than current SAR test pricing. (3) Versatility : MR-RFET enables scanning of complex anatomical structures in higher 3D resolution (sub-millimeter vs. millimeter). Since the MR-RFET method estimates temperature changes it is also a more relevant measure of human health risks.

RF Test Labs’ goal is to obtain an 8% share of the market within 5 years of operation, which equates to $110.6M in revenues. The RF Test Labs’ founding team consists of three Ph.D. candidates and a post doctoral fellow experienced in MR research and work-ing at NYU’s Center for Biomedical Imaging. In the picture are Cem Murat Deniz, Daniel Bain, Leeor Alon, Gene Cho, and Iliyana Atanasova (L -> R).

global Joint research proJect in indUstrial original field

Korea Evaluation Institute of Industrial Technology (KEIT) and KSEA have been working together to increase the participation of Korean-American scientists and engineers for KEIT global joint research projects. KSEA performed a joint research demand survey for “A new project for 2012 Industry Fusion Original Technology Development Business” that facilitated the joint R&D projects between Korean-American scientists and engineers and Korean companies, sponsored by KEIT. Since the 1st announcement in January, 2012, 110 survey forms in the fields of information communication and new innovative industry areas were received from 74 Korean Americans. The total survey participants were categorized as the university researchers with 77 surveys and industry researchers with 25. After the extensive and objective peer review process, five proposals were selected, and, currently, the contract agreement process between KEIT and fiving winning teams with participants from USA are under way.

Among the five finalists, three of them were KSEA members: Dr. Dong Sam Ha, Dr. Jaehwan John Lee and Dr. Gang-Ryung Uh. Dr. Jaehwan John Lee is Associate Professor of Electrical and Computer Engineering at Indiana University-Purdue University In-dianapolis. His proposed research project was titled, “Software development for the big database analysis and management based on the next generation memory technology”, and will be undertaken jointly with Dr. Sung Jin Huh of ETRI. Dr. Gang-Ryung Uh is Associate Professor of Computer Science Department at Boise State University and He will conduct a research project titled, “Sensor terminal supporting software and applied service development based on smart device to provide a personalized service,” jointly with Dr. Doohwan Shin at Moneual, a home media system company in Korea.

Particularly, Dr. Ha, Professor of Department Electrical and Computer Engineering at Virginia Tech University, has served as pro-gram chair of 2011 UKC in Seattle and the President of Southern Virginia Chapter of KSEA. The proposed project was to develop a combined switching system technology for the Next Generation Optical Transport Network. The principal investigator of the joint project Dr. Jong Hyun Lee of Electronics and Telecommunications Research Institutes (ETRI) where Prof. Ha is to participate in developing 400G Optical Transceiver. The market size for the combined switching and transmission equipment is expected to grow to 50-billion dollars in 2020, and the proposed project will generate significant economic effects. Recently, Dr. Ha wrote to President Hosin Lee, “Yes, I have received a research project from ETRI through KETI. I greatly appreciate KSEA for providing such an op-portunity. Another reason to buy beer to you!”

KSEA is under a contract agreement with KEIT in devel-oping research problem statements to be considered by KEIT for the next fiscal year. The project team includes Prof. Hosin Lee of University of Iowa, Prof. Yongho Sohn of Central Florida Univesity, Prof. Hanseup Kim of Uni-versity of Utah, Dr. Kyungjae Myung of NHI, Hyunggun Kim of University of Texas Medical School at Houston, Benjamin Lee of INVIA Medical Imaging Solutions, and Office Manager Euna Yoon of KSEA. KSEA members submitted over 70 problem statements to KEIT that will be considered by KEIT staff when they are to develop the request for proposals next year. As a token of apprecia-tion, $50 will be provided to each of all KSEA members who submitted problem statements. By suggesting emerg-ing research topics at the very early stage of developing requests for proposals, if the suggested topic is selected, everyone will be invited to submit the proposals includ-ing ones who provided the seeds for developing requests for proposals in the process. Recently, President Hosin Lee visited KEIT to discuss about the progress in identifying industry research topics to be considered next year and future collaborations between KSEA and KEIT. A cooperative relationship between KSEA and KEIT was initiated during the 40th term and the outcome is mutually beneficial to both KSEA members and KEIT staff. Therefore, this win-win relationship is expected to grow in the future.

Ksea-snU MoU cereMonY

president lee participates at the start-Up festival & signs an MoU With snU

On May 30, 2012, the national Start-up Festival was held on campus of Seoul National University (SNU) where over 1500 students from 70 universities participated. The main purpose of the national Start-up Festival was to create a national network of students who are interested in getting an education on how to start a new venture company. As part of the national Start-up Festival, Presi-dent Hosin Lee was invited to give a presentation to professors and staff from over 70 universities about the start-up college educa-tion programs in USA. During his presentation, he introduced the KSEA and the KSEA business venture challenge held during YGTLC 2012 in San Francisco. He also played the YGTLC 2012 video to all participants. Three winners from the KSEA business challenge were also invited to give presentations to all participants. Minister Ju-Ho (check the spelling) Lee of MEST and President Lee also attended the outdoor event of matching students with mentors in the afternoon. The start-up festival was a great success.

On June 1, a Memorandum Of Understanding (MOU) was established between KSEA and SNU R&DB Foundation towards devel-oping strategic cooperative relationship in the field of science and technology. SNU R&DB Foundation was established in 2008 to manage research fund and intellectual property of University and have mainly focused on performing government-aided research and joint research contracts with industries.

The signing ceremony took place at the SNU R&DB Foundation office on campus of Seoul National University. Prof. Hosin Lee, President of KSEA, and Prof. Jun-shik Lee, Director of SNU R&DB Foundation signed the MOU document taking the first step on the path towards the mutual cooperation in the future. With this agreement, both parties will cooperate on a mutually beneficial and complementary basis in planning and implementing joint projects and joint workshops in the field of science and technology. This MOU is the tenth one that was signed during the 40th term and, like the one signed between KSEA and KEIT on July 1, 2011, it is expected that all of them would lead to more collaborative projects and workshops in the future.

KSEA started a Pilot High School Physics Contest (HSPC) this year. The objective of Physics Contest is to promote interest in phys-ics as a fundamental science. It was open to all high school students in grades 9 through 12 in North Carolina (Raleigh) and North Texas chapters as a pilot program before expanding to national level. The level of problems was set to High school physics (Algebra based). 14 students participated in the competition this year.

Out of 2312 participants for the Math Competition, KSEA recognized three top-scoring students from each grade, 4th through 11th, as national winners. These students represent states of Virginia, Washington, Texas, Georgia, North Carolina, California, Illinois, Ohio, and New Jersey. Each national winner was awarded with a certificate and a check of $500, $400, $350 for the 1st, 2nd, and 3rd places, respectively. The winners are summarized in the table below:
