A parallel method for finding the convex hull of discs (2002)

We present a parallel method for finding the convex hull of a set of discs in the CREW PRAM model. We show that the convex hull of n discs can be computed in O(log/sup 1+/spl epsiv// n) time using O(n/log/sup /spl epsiv// n) processors, where /spl epsiv/ is any positive constant. We also show that it can be constructed in O(log n loglog n) time using O(n log n) processors. The first result achieves cost optimal and the second one runs faster. The main technique which we used in the algorithm is a complex divide-and-conquer technique.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Improving Identity Management of Cloud-Based IoT Applications Using Blockchain (2018)

Identity Management (IDM) in cloud-based Internet-of-Things (IoT) applications is critical in many businesses. However, most conventional IDM systems are costly and hinder the innovation and greater customer experience. By using blockchain, a new way of managing the identities is proposed. This paper presents an initiative to improve IDM by integrating face recognition approach and blockchain technology in an integrated IoT -cloud application. To illustrate the proposed initiative, a decentralized campus wide printing service is chosen as a use case. In this use case, face recognition is used as an entry point to the service. Since face recognition involves a lot of complex computations and machine learning, this process is executed on a cloudlet, hence minimizing the need for massive data transfer to a distant cloud. Once a user's login information is digitally verified via immutable blockchain, smart contract is deployed to keep track of the user's printing activities. The integration of blockchain in this service has decentralized the IDM, automated the service, and kept the service inexpensive and transparent.
Transcalibur (2018)

We introduce a dynamic weight moving VR controller for 2d haptic shape rendering using a haptic shape illusion. This allows users to perceive the feeling of various shapes in virtual space with a single controller. We designed a device that drives weight on a 2d planar area to alter mass properties of the hand-held controller. Our user study showed that the system succeeded in providing shape perception over a wide range.
Search for Isotope Effect in Superconducting Y-Ba-Cu-O (1987)

An isotope effect has been searched for in the high-${T}_{c}$ superconductor $\mathrm{Y}{\mathrm{Ba}}_{2}{\mathrm{Cu}}_{3}{\mathrm{O}}_{7\ensuremath{-}\ensuremath{\delta}}$ through substitution of $^{18}\mathrm{O}$ for $^{16}\mathrm{O}$. No shift in the superconducting transition temperature ${T}_{c}$ is observed by electrical resistivity or magnetic susceptibility measurements. We discuss the implications of this result for mechanisms of superconductivity in the high-${T}_{c}$ oxides.
Linear search algorithm for repair analysis with 4 spare row/4 spare column (2002)

An intelligent method of repair analysis that can repair a RAM block with 4 spare rows and 4 spare columns is implemented with CAM that has the function of datamatch, count-sub-entry, search-empty-entry. The key idea of this algorithm is on-the-fly repair analysis by rearrangement of the CAM array contents and repair analysis processing by one row or one column unit with a dual error buffer.
Near‐IR dyes in three‐color volumetric capillary cytometry: Cell analysis with 633‐ and 785‐nm laser excitation (1995)

Several fluorescent dyes that absorb in the near-infrared are described. The photostability and aggregation properties of the dyes were examined. Two of the dyes, BHMP and BHDMAP, emit at 805 nm and were useful dyes for protein labeling. A dual-laser, three-color scanning instrument was constructed. CD3+CD4+ and CD3+CD8+ populations were enumerated in undiluted, whole blood based on the fluorescence of Cy5, Cy5.5 and BHMP.
A systematic review of smartphone applications for smoking cessation (2017)

Tobacco use is the leading cause of preventable disease and death in the USA. However, limited data exists regarding smoking cessation mobile app quality and intervention effectiveness. Innovative and scalable interventions are needed to further alleviate the public health implications of tobacco addiction. The proliferation of the smartphone and the advent of mobile phone health interventions have made treatment more accessible than ever. The purpose of this review was to examine the relation between published scientific literature and available commercial smartphone health apps for smoking cessation to identify the percentage of scientifically supported apps that were commercially available to consumers and to determine how many of the top commercially available apps for smoking cessation were supported by the published scientific literature. Adhering to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, apps were reviewed in four phases: (1) identified apps from the scientific literature, (2) searched app stores for apps identified in the literature, (3) identified top apps available in leading app stores, and (4) determined which top apps available in stores had scientific support. Seven articles identified six apps with some level of scientific support, three (50%) were available in at least one app store. Conversely, among the top 50 apps suggested by each of the leading app stores, only two (4%) had any scientific support. While half of the scientifically vetted apps remain available to consumers, they are difficult to find among the many apps that are identified through app store searches.
SPIN-IT: the PRISM project network protocol for image retrieval (2002)

The PRISM project was created to explore technologies for sharing pictures in a wireless network of imaging devices, including image discovery techniques, data routing, source and channel coding, and techniques for image mosaicing and image fusion (i.e., super-resolution). Through the PRISM project, we have developed a routing protocol for wireless ad hoc networks that supports efficient image retrieval based on metadata queries. In digital photography, metadata describes captured information about an image and provides the key element needed for advanced techniques for sharing pictures. Using metadata, devices connected to a wireless network can advertise data availability and query for desired data. These devices will, however, operate within a constrained environment - energy resources may often be limited, computational power may be minimal, and the wireless network bandwidth and range will likely be constrained. Our goal was to find an efficient way to utilize metadata to retrieve images in a wireless network of imaging devices while conserving energy and bandwidth. Building on the SPIN protocol for metadata negotiation, we designed SPIN-IT (Sensor Protocols for Information via Negotiation Image Transfer), a protocol where wireless imaging devices use metadata queries to retrieve desired pictures. This protocol provides low bandwidth query-based communication prior to the transfer of image data to set up routes to desired data rather than routes to specific nodes, making SPIN-IT a data-centric routing protocol. However, the advantage of a centralized approach is that the overhead and delay in finding the location of desired data is reduced. We simulated both SPIN-IT and the centralized model using the discrete event simulator ns, and we measured the delay and overhead incurred by each REQ for the different approaches. We describe the results of these initial experiments that determine when SPIN-IT is an efficient protocol for image retrieval in a wireless network.
Establishment of a human pancreatic cancer cell line and detection of pancreatic cancer associated antigen. (1984)

We succeeded in an establishment of a human pancreatic cancer cell line (PK-1) from liver metastasis of pancreatic cancer. Primary pancreatic cancer cells grew as islands surrounded by fibroblastic cells. However, these fibroblastic cells were gradually omitted by the polygonal shaped cancer cells. This cell line contained neither zymogen granules nor trypsin indicating that this pancreatic cancer originated from pancreatic duct cells. Modal chromosome numbers of this cell line were 42 and 72 and the doubling time was 48 hr. This cell line was transplantable in athymic nude mice to form progressive tumors which had histology similar to that of the original cancer (papillotubular adenocarcinoma). Neither AFP nor ferritin but CEA was detected on the surface and in the cytoplasm of this cell line in indirect immunofluorescence. Rabbit antiserum against this pancreatic cancer cell line detected pancreatic cancer associated antigen besides CEA in the culture supernatant. This antiserum reacted with sera from patients with pancreatic cancer to form a distinct precipitin line in agarose gel which fused with the precipitin line formed between the culture supernatant of this cell line and the antiserum.
Efficacy of Argentine propolis formulation for topical treatment of canine otitis externa (2010)

The therapeutic effects of Argentine propolis ear drop formulation on canine otitis externa were evaluated. Forty-eight dogs with symptoms of otitis externa were randomly assigned to double-blinded, controlled clinical trial to evaluate the efficacy of topical formulation with propolis versus a topical placebo in the treatment of otitis externa. The propolis preparation and placebo were administrated into both external ear canals, twice daily for 14 days. Throughout the study, clinical examination and microbiological analysis of dogs ear exudates were made. The most frequent microorganisms isolated in culture media were: Malassezia pachydermatis (54.2%), Staphylococcus aureus (43.8%), coagulase-negative Staphylococcus (25.0%), Pseudomonas aeruginosa (20.8%), Candida albicans (18.8%), Proteus mirabilis (16.7%), Streptococcus spp. (16.7%), Enteroccocus faecalis (12.5%), Escherichia coli (12.5%), Staphylococcus intermedius (6.3%), Klebsiella spp. (4.2%), andCandida glabrata (2.1%). Whereas the control group did not recover from the infectious ear disease, the propolis preparation exhibited antimicrobial activity against most of the microorganisms isolated from samples of the treated group. In addition, no propolis-adverse effects were observed. This allowed propolis-treated patients to show a significant improvement of the clinical parameters. Thus, this new Argentine propolis ear drop formulation may be used for topical treatment of otitis externa in dogs.
HIV-1 Nef Enhances Both Membrane Expression and Virion Incorporation of Env Products (2004)

The expression of human immunodeficiency virus Nef increases the viral infectivity through mechanisms still not fully elucidated. Here we report that wild-type (wt) human immunodeficiency virus, type 1 (HIV-1), particles were neutralized by higher concentrations of either anti-Env glycoprotein (gp) 41 antibodies or recombinant soluble human CD4 compared with Deltanef HIV-1. This appeared to be the result of a Nef-induced increase of virion incorporation of both gp41 (transmembrane (TM)) and surface gp120 Env products likely originating from enhanced steady-state levels of cell membrane-associated Env products. This, in turn, seemed to be the consequence of a reduced retention of the Env precursor. Most interesting, we found that both the Nef-directed increase of Env membrane expression and the Nef-induced enhancement of HIV-1 infectivity relied on the presence of the intracytoplasmic domain of TM, supporting the hypothesis of a functional correlation between these effects. Mutagenesis studies allowed us to establish that the two leucine residues at the TM C terminus, which are part of a sorting motif involved in the control of Env membrane expression, and the 181-210-residue Nef C-terminal region were critically involved in the Nef/Env functional interaction. In conclusion, we propose that Nef increases the infectivity of HIV-1 at least in part by enhancing the amounts of Env products incorporated into virus particles.

Coordination Versatility of sp<sup>3</sup>-Hybridized Pincer Ligands toward Ligand–Metal Cooperative Catalysis (2012)

Pincer-type complexes occupy a very important position in chemistry and chemistry-related disciplines. In this article we have selected several spectacular examples of pincer systems and demonstrate that reversible structural changes in the ligand backbone may have a dramatic impact on the reactivity of their metal complexes. This perspective aims to focus on some recent exciting developments in the chemistry of “cooperating” PN(sp3)P and PC(sp3)P pincer ligands relevant to catalytic applications.
<title>Infrared fiber optic sensor for measurements of nonuniform temperature distributions</title> (1992)

Infrared (IR) fiber optic radiometry of thermal surfaces offers several advantages over refractive optics radiometry. It does not need a direct line of sight to the measured thermal surface and combines high capability of monitoring small areas with high efficiency. These advantages of IR fibers are important in the control of nonuniform temperature distributions, in which the temperature of closely situated points differs considerably and a high spatial resolution is necessary. The theoretical and experimental transforming functions of the sensor during scanning of an area with a nonuniform temperature distribution were obtained and their dependence on the spacial location of the fiber and type of temperature distribution were analyzed. Parameters such as accuracy and precision were determined. The results suggest that IR fiber radiometric thermometry may be useful in medical applications such as laser surgery, hyperthermia, and hypothermia.
Transformation Algorithms for Data Streams (2005)

Next generation data processing systems must deal with very high data ingest rates and massive volumes of data. Such conditions are typically encountered in the intelligence community (IC) where analysts must search through huge volumes of data in order to gather evidence to support or refute their hypotheses. Their effort is made all the more difficult given that the data appears as unstructured text that is written in multiple languages using characters that have different encodings. Human analysts have not been able to keep pace with reading the data and a large amount of data is discarded even though it might contain key information. The goal of our project is to assess the feasibility of incrementally replacing humans with automation in key areas of information processing. These areas include document ingest, content categorization, language translation, and context- and temporally-based information retrieval
Immunocytochemical localization and identification of the major surfactant protein in adult rat lung. (1981)

We investigated the cellular and subcellular sites of metabolism of the 72,000 dalton protein of pulmonary surfactant in order to provide insights into mechanisms of synthesis, intracellular assembly, and intraalveolar metabolism of this phospholipid-rich secretory product. Surfactant (approximately 90% lipid, 10% protein by weight) was purified by density gradient centrifugation of material obtained by lavaging rat lungs. The purified material was used to generate an antiserum from which a specific antibody was obtained by affinity chromatography. A horseradish peroxidase-labeled Fab was used to localize the antigen in rat lung. The antibody labeled the rough endoplasmic reticulum and Golgi apparatus of type II cells only. Some multivesicular bodies in type II cells were also labeled, but whether the antigen was present in lamellar bodies was uncertain. Phagosomes of alveolar macrophages were labeled as were similar inclusions in type I cells. Using indirect immunocytochemistry we determined that the labeling of alveolar cell surfaces does not represent the presence of a continuous layer of secreted surfactant. These results suggest that only the type II cell synthesizes surfactant protein and than mainly alveolar macrophages participate in its catabolism. The initial intracellular site of the association of protein with lipid may be multivesicular bodies as suggested previously by others.
Probability Distribution Functions Based Face Recognition System Using Discrete Wavelet Subbands (2011)

Face recognition has recently been the centre of attention of many researchers (Jain et al. 2004). The earliest work in digital face recognition was reported by Bledsoe in 1964. Statistical face recognition systems such as principal component analysis (PCA) based eigenfaces introduced by Turk and Pentland in 1991, attracted lots of attention. Fisherfaces method based on linear discriminant analysis was introduced later on by Belhumeur et al. (1997). Many of these methods are based on grey scale images; however colour images are increasingly being used since they add additional biometric information for face recognition (Marcel and Bengio, 381). PDFs obtained from different colour channels of a face image can be considered as the signature of the face, which can be used to represent the face image in a low dimensional space (Demirel and Anbarjafari, VISSAP 2008). Images with small changes in translation, rotation and illumination still possess high correlation in their corresponding PDFs. PDF of an image is a normalized version of an image histogram which have been used in many image processing applications such as object detection (Laptev, 2006) and face recognition (Yoo and Oh, 1999; Rodriguez and Marcel, 2006; Demirel and Anbarjafari, IEEE Signal Processing Letter, 2008). Nowadays, wavelets have been used quite frequently in image processing. It has been used for feature extraction (Wang and chen, 2006), denoising (Starck et al., 2002), compression (Lamard et al. 2005), and face recognition (Liu et al., 2007; Demirel et al., 2008). The decomposition of images into different frequency ranges permits the isolation of the frequency components introduced by “intrinsic deformations” or “extrinsic factors” into certain subbands (Dai and Yan, 2007). This process results in isolating small changes in an image mainly in high frequency subband images. Hence discrete wavelet transform (DWT) is a suitable tool to be used for designing pose invariant face recognition system. Another important issue in face recognition system is face localization. There are several methods for this task such as skin tone based face localization for face segmentation. Skin is
A heat‐resistant silicon‐based polymer (1997)

Materials combining the best properties of plastics and ceramics , i.e., that are as heat and combustion resistant as ceramics and as moldable and light as plastics, would find many applications. As a step in this direction, the preparation and properties of a silicon‐based organic polymer, MSP, which includes the Si(H)–C unit, and related polymers are described. MSP's extremely high temperature of 5% weight loss (860°C) indicates that further investigation of polymers containing the Si(H)–C unit could be fruitful.
Optically self-locked semiconductor laser with servo control for feedback phase and laser current (1991)

The operating current of a semiconductor laser optically locked to a high-finesse reference cavity can be controlled using a second-harmonic lock-in technique. The authors present theoretical calculations for this novel servo scheme. For stabilization and noise reduction of semiconductor lasers, the optical lock to a high-finesse cavity with a feedback phase servo has become a standard technique. An additional servo for the laser current is desirable for combining good tuning capability and high spectral purity. It is demonstrated that such a servo can easily be established with no changes in the optical setup. The practical applicability of this technique has been demonstrated in a setup with a 780-mm laser diode.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Characterization of Surface Free Energy of Cathode Materials for Lithium-ion Batteries (2013)

Li-ion 이차전지 양극재인 LiMn2O4는 성공적으로 상업화되었고, EV 및 HEV용 양극재 후보로서 각광을 받고 있으나 금속용출로 인한 비가역용량의 증가가 걸림돌이 되고 있다. 금속용출특성은 주로 ICP 혹은 AAS를 이용하여 측정되고 있는데, 짧게는 일주일에서 길게는 수주까지 시간이 소요되었고 간접적인 양극재의 특성을 알 수 밖에 없었다. 
본 연구에서는 측정시간이 수시간에서 수일 내이며 양극재의 직접적인 특성을 알 수 있는 표면자유에너지 분석을 통하여 용출특성을 예측하고자 실험을 진행하였으며, 표면자유에너지와 금속용출간의 강한 상관관계를 확인하였다. 전극은 Sessil drop 방식으로 파우더는 Adsorption 방식으로 접촉각을 측정하여 표면자유에너지를 계산하였는데, Polarity(Acidity, Basicity)가 Dispersity에 비해 주도적으로 금속용출에 영향을 미치는 것을 확인할 수 있었다. Polarity는 Al2O3의 코팅량이 증가할수록 감소하는 것을 뚜렷이 확인할 수 있었으며, Dispersity는 Al2O3 의 특성에 근접하는 것을 확인하였다. 파우더에서 전극으로 코팅되면서 Basicity가 감소하는 것을 확인할 수 있었는데 코팅시 조건을 최적화하여 금속용출량을 감소시킬 수 있을 것으로 생각된다. 결정구조에 따른 표면자유에너지와 용출과의 상관관계도 분명히 확인할 수 있었다. 
결론적으로 본 연구에서는 양극재의 표면자유에너지특성분석으로 용출특성 예측 및 표면(코팅, 결정구조) 변화에 따른 특성변화 분석이 가능하며, 특성최적화의 척도로서 이용될 수 있다는 사실을 확인하였다. ⓒ 2013 DGIST
Presidential address to the American Association of Immunologists. Stimulating naive T cells. (1999)

Being introduced for this address by Jacques Miller, my Ph.D. supervisor 30 years ago, gives me particular pleasure because Jacques has always been a hero of mine, and I consider myself very fortunate to have had the opportunity to train in the lab of one of the great figures in immunology.[⇓][1
Expandable Mg-based Helical Stent Assessment using Static, Dynamic, and Porcine Ex Vivo Models (2017)

A bioresorbable metallic helical stent was explored as a new device opportunity (magnesium scaffold), which can be absorbed by the body without leaving a trace and simultaneously allowing restoration of vasoreactivity with the potential for vessel remodeling. In this study, developed Mg-based helical stent was inserted and expanded in vessels with subsequent degradation in various environments including static, dynamic, and porcine ex vivo models. By assessing stent degradation in three different environments, we observed: (1) stress- and flow-induced degradation; (2) a high degradation rate in the dynamic reactor; (3) production of intermediate products (MgO/Mg(OH)<sub>2</sub> and Ca/P) during degradation; and (4) intermediate micro-gas pocket formation in the neighboring tissue ex vivo model. Overall, the expandable Mg-based helical stent employed as a scaffold performed well, with expansion rate (>100%) in porcine ex vivo model.
