A High-Quality Occlusion Filling Method Using Image Inpainting (2010)

본 논문에서는 한 장의 기준 영상과 그에 상응하는 참 깊이 맵을 이용하여 가상의 다중 시점 영상 생성 시 발생하는 가려짐 영역 보간 방법을 제안한다. 이 방법은 영상 인페인팅 기술과 각각의 깊이 정도에 따른 층별 보간 기술을 이용한다. 우선, 기준 영상을 깊이 정보에 따라 여러 개의 층으로 분할한다. 각각의 층에 대해 가려짐 영역 내의 화소들은 영상 인페인팅 기술을 이용하여 보간한다. 마지막 단계 에서 개별적으로 보간된 층 영상들은 하나로 합성되어 가상 시점의 영상을 이룬다. 영상을 깊이 정보에 따라 분할함으로써, 각 깊이 정도에 대한 텍스처의 연관성을 보존하며 보간할 수 있으므로 기존의 방법에 비하여 보다 정확하고 세밀한 가려짐 영역 보간이 가능하다. 본 논문에서는 여러 가지 실험 결과를 통하여 제안한 방법의 효율성을 입증하였다. In this paper, we propose a method for filling out the occlusions in generating multi-view images from one source image and its ground-truth depth image. The method is based on image inpainting and layered interpolation. The source image is first divided into several layers using depth information. The occlusions are interpolated separately in every layered image using the image inpainting algorithm. Finally, the interpolated layered images are combined to obtain different viewpoint images. Interpolating occlusions with depth-correlated texture information that is contained to each layer makes it possible to obtain more detailed and accurate results than previous methods. The effectiveness of the proposed method is shown through experimental results.
Hydrogen-1 MR Spectroscopy for Measurement and Diagnosis of Hepatic Steatosis (2012)

Hydrogen-1 MR spectroscopy is an effective, noninvasive technique that can be used to diagnose and quantify hepatic steatosis. Hydrogen-1 MR spectroscopy thresholds corresponded with histopathologic grades and may be useful in the workup of patients with elevated transaminase concentrations.
Extracting the Green’s function from the correlation of coda waves: A derivation based on stationary phase (2004)

The Green's function of waves that propagate between two receivers can be found by cross-correlating multiply scattered waves recorded at these receivers. This technique obviates the need for a source at one of these locations, and is therefore called "passive imaging." This principle has been explained by assuming that the normal modes of the system are uncorrelated and that all carry the same amount of energy (equipartitioning). Here I present an alternative derivation of passive imaging of the ballistic wave that is not based on normal modes. The derivation is valid for scalar waves in three dimensions, and for elastic surface waves. Passive imaging of the ballistic wave is based on the destructive interference of waves radiated from scatterers away from the receiver line, and the constructive interference of waves radiated from secondary sources near the receiver line. The derivation presented here shows that the global requirement of the equipartitioning of normal modes can be relaxed to the local requirement that the scattered waves propagate on average isotropically near the receivers.
Polymer–Inorganic Core–Shell Nanofibers by Electrospinning and Atomic Layer Deposition: Flexible Nylon–ZnO Core–Shell Nanofiber Mats and Their Photocatalytic Activity (2012)

Polymer-inorganic core-shell nanofibers were produced by two-step approach; electrospinning and atomic layer deposition (ALD). First, nylon 6,6 (polymeric core) nanofibers were obtained by electrospinning, and then zinc oxide (ZnO) (inorganic shell) with precise thickness control was deposited onto electrospun nylon 6,6 nanofibers using ALD technique. The bead-free and uniform nylon 6,6 nanofibers having different average fiber diameters (∼80, ∼240 and ∼650 nm) were achieved by using two different solvent systems and polymer concentrations. ZnO layer about 90 nm, having uniform thickness around the fiber structure, was successfully deposited onto the nylon 6,6 nanofibers. Because of the low deposition temperature utilized (200 °C), ALD process did not deform the polymeric fiber structure, and highly conformal ZnO layer with precise thickness and composition over a large scale were accomplished regardless of the differences in fiber diameters. ZnO shell layer was found to have a polycrystalline nature with hexagonal wurtzite structure. The core-shell nylon 6,6-ZnO nanofiber mats were flexible because of the polymeric core component. Photocatalytic activity of the core-shell nylon 6,6-ZnO nanofiber mats were tested by following the photocatalytic decomposition of rhodamine-B dye. The nylon 6,6-ZnO nanofiber mat, having thinner fiber diameter, has shown better photocatalytic efficiency due to higher surface area of this sample. These nylon 6,6-ZnO nanofiber mats have also shown structural stability and kept their photocatalytic activity for the second cycle test. Our findings suggest that core-shell nylon 6,6-ZnO nanofiber mat can be a very good candidate as a filter material for water purification and organic waste treatment because of their photocatalytic properties along with structural flexibility and stability.
Systematic discovery and characterization of regulatory motifs in ENCODE TF binding experiments (2013)

Recent advances in technology have led to a dramatic increase in the number of available transcription factor ChIP-seq and ChIP-chip data sets. Understanding the motif content of these data sets is an important step in understanding the underlying mechanisms of regulation. Here we provide a systematic motif analysis for 427 human ChIP-seq data sets using motifs curated from the literature and also discovered de novo using five established motif discovery tools. We use a systematic pipeline for calculating motif enrichment in each data set, providing a principled way for choosing between motif variants found in the literature and for flagging potentially problematic data sets. Our analysis confirms the known specificity of 41 of the 56 analyzed factor groups and reveals motifs of potential cofactors. We also use cell type-specific binding to find factors active in specific conditions. The resource we provide is accessible both for browsing a small number of factors and for performing large-scale systematic analyses. We provide motif matrices, instances and enrichments in each of the ENCODE data sets. The motifs discovered here have been used in parallel studies to validate the specificity of antibodies, understand cooperativity between data sets and measure the variation of motif binding across individuals and species.

Phase I AIDS Clinical Trials Group (075) study of adriamycin, bleomycin and vincristine chemotherapy with zidovudine in the treatment of AIDS-related Kaposiʼs sarcoma (1994)

The maximum tolerated dose of doxorubicin is 10 mg/m2 when given in combination with zidovudine and BV chemotherapy. Response rates observed with the combined antiretroviral and chemotherapy regimen are similar to those previously reported with ABV chemotherapy alone.
Highly Effective Adsorption of Heavy Metal Ions by a Thiol-Functionalized Magnesium Phyllosilicate Clay (2001)

A thiol-functionalized layered magnesium phyllosilicate material (called Mg-MTMS), prepared by a direct and cost-effective co-condensation synthesis, has been investigated as a high-capacity adsorbent for heavy metal ions. Structural characterization by powder X-ray diffraction, infrared spectroscopy, solid-state 13C and 29Si NMR spectroscopies, and elemental analyses confirms the smectite-type structure and the high organic moiety content of this material. Mg-MTMS was found to be highly effective for the adsorption of Hg(II), Pb(II), and Cd(II) ions, exhibiting unprecedented metal ion uptake capacities of 603, 365, and 210 mg of metal/g of adsorbent, respectively. Mg-MTMS shows an equivalent affinity for the three metal ions, removing them from mixed metal solutions with an equal ion uptake capacity (approximately 400 mg of metal/g of adsorbent). Metal-loaded Mg-MTMS can be regenerated by acid treatment without altering the adsorbent properties. The high effectiveness of Mg-MTMS for the capture of metal ions is attributed to both the high concentration of complexing thiol groups (6.4 mmol of SH/g of Mg-MTMS) and the expansion capability of the framework, which facilitates the accessibility of the binding sites.
Lifting the Spectral Crosstalk in Multifluorophore Assemblies (2017)

A general strategy for measuring the energy-transfer efficiencies in multifluorophore assemblies is demonstrated. The present method is based on spectral shaping of the excitation light with molecular solutions representing donor and acceptor fluorophores, which causes a suppressed excitation of the respective donor and acceptor molecules in the sample. The changes in the acceptor emission resulting from spectral shaping of the excitation light are then used to determine the energy-transfer efficiencies (Ex) associated with all participating donor–acceptor pairs. Here, the technique is demonstrated through energy-transfer (ET) measurements in a 4-fluorophore construct featuring a DNA supported assembly of three donor/donor-relay (Cy3, Cy3.5, and Cy5) and one acceptor (Cy5.5) molecules. The resulting Ex were validated using the standard photoluminescence (PL) quenching approach as well as measurements of partial 2- and 3-dye assemblies. The present work highlights general benefits of the spectrally shaped excitation approach to measuring donor–acceptor energetics, including the ability to resolve the spectral cross talk between multiple fluorophores and to exclude charge transfer contributions into donor PL quenching.
Nanofiber Fabry–Perot microresonator for nonlinear optics and cavity quantum electrodynamics (2012)

We experimentally realize a Fabry-Perot-type optical microresonator near the cesium D2 line wavelength based on a tapered optical fiber, equipped with two fiber Bragg gratings that enclose a subwavelength diameter waist. Owing to the very low taper losses, the finesse of the resonator reaches F=86 while the on-resonance transmission is T=11%. The characteristics of our resonator fulfill the requirements of nonlinear optics and cavity quantum electrodynamics in the strong coupling regime. These characteristics, combined with the demonstrated ease of use and advantageous mode geometry, open a realm of applications.
A tutorial on convex optimization (2004)

In recent years, convex optimization has become a computational tool of central importance in engineering, thanks to it's ability to solve very large, practical engineering problems reliably and efficiently. The goal of this tutorial is to give an overview of the basic concepts of convex sets, functions and convex optimization problems, so that the reader can more readily recognize and formulate engineering problems using modern convex optimization. This tutorial coincides with the publication of the new book on convex optimization, by Boyd and Vandenberghe, who have made available a large amount of free course material and links to freely available code. These can be downloaded and used immediately by the audience both for self-study and to solve real problems.
Synthesis of N-Demethyl-N-Substituted Dihydroisomorphine and Dihydroisocodeine Derivatives<sup>+</sup> (1992)

Abstract Several new N-demethyl-N-alkyl derivatives (1p, 1r, 1s, 1m, 1n and 1o) of dihydroisomorphine and dihydroisocodeine, and N-demethyl-N-cyclopropylmethylisocodeine (2g) have been prepared. The presented synthetic procedure allows a convenient access to a series of structurally related, stereochemically homogeneous substances for studies of the agonist/antagonist properties.
Scalable video transmission over multiuser MIMO-OFDM systems (2010)

With the proliferation of wireless services, multimedia interactivities are quickly becoming ubiquitous. As multimedia traffics generally have large packets volume, high data rate requirements in wireless transmission are critical. Next generation wireless systems, e.g., multiple-input multiple-outp
<title>Design of nonimaging lenses and lens-mirror combinations</title> (1991)

A new method of design of nonimaging concentrators is presented and two new types of concentrators are developed. The first one is an aspheric lens, and the second one is a lens- mirror combination. A ray tracing of 3-D concentrators (with rotational symmetry) has also been done, showing that the lens-mirror combination has a total transmission as high as that of the full compound parabolic concentrators, while their depth is much smaller than the classical parabolic mirror-nonimaging concentrator combinations (8 times smaller or more). Another important feature of this concentrator is that the optical surfaces are not in contact with the receiver, as occurs in other nonimaging concentrators.
Capacity Analysis of IEEE 802.11ah WLANs for M2M Communications (2013)

Focusing on the increasing market of the sensors and actuators networks, the IEEE 802.11ah Task Group is currently working on the standardization of a new amendment. This new amendment will operate at the sub-1GHz band, ensure transmission ranges up to 1 Km, data rates above 100 kbps and very low power operation. With IEEE 802.11ah, the WLANs will offer a solution for applications such as smart metering, plan automation, eHealth or surveillance. Moreover, thanks to a hierarchical signalling, the IEEE 802.11ah will be able to manage a higher number of stations (STAs) and improve the 802.11 Power Saving Mechanisms. In order to support a high number of STAs, two different signalling modes are proposed, TIM and Non-TIM Offset. In this paper we present a theoretical model to predict the maximum number of STAs supported by both modes depending on the traffic load and the data rate used. Moreover, the IEEE 802.11ah performance and energy consumption for both signalling modes and for different traffic patterns and data rates is evaluated. Results show that both modes achieve similar Packet Delivery Ratio values but the energy consumed with the TIM Offset is, in average, a 11.7% lower.
Australian Journal of Chemistry: An International Journal for Chemical Science (2008)

Reversible addition-fragmentation chain transfer (RAFT) is one of the most useful new technique which is developed in radical polymerisation that allow unprecedented control over molecular weight distribution as well as over the structure of the final product. RAFT research has undergone a change in focus away from the study of the scope and mechanism of RAFT polymerisation towards applications of the process.
<i>N</i>,<i>N</i>-Diaryl Dihydrophenazines as Photoredox Catalysts for PET-RAFT and Sequential PET-RAFT/O-ATRP (2018)

<i>N,N</i>-Diaryl dihydrophenazines are employed as organic photoredox catalysts (PCs) for photoinduced electron/energy transfer-reversible addition-fragmentation chain transfer (PET-RAFT) polymerization. The ability of these PCs to mediate PET-RAFT is heavily dependent on the ability of the PC to access a photoexcited intramolecular charge transfer state. The use of PCs displaying intramolecular charge transfer in the excited state allows for efficient PET-RAFT of a variety of monomers, including vinyl acetate, and in a wide range of solvents. The ability of these PCs to also mediate organocatalyzed atom transfer radical polymerization (O-ATRP) is exploited to perform a sequential PET-RAFT/O-ATRP block copolymerization of PMA-<i>b</i>-PMMA using the same PC for both polymerizations.
Abstract P1-05-04: Expression of Quiescin Sulfhydryl Oxidase 1 is associated with a highly invasive phenotype and correlates with a poor prognosis in Luminal B breast cancer. (2012)

Abstract Quiescin sulfhydryl oxidase 1 (QSOX1) oxidizes sulfhydryl groups to form disulfide bonds in proteins. Informatic analysis using the newly available “Gene Expression Based Outcome for Breast Cancer Online” (GOBO) tool indicated high levels of QSOX1 expression in Estrogen Receptor positive (ER+) subtypes of breast cancer. We confirmed this finding by evaluation of QSOX1 protein expression in breast tumors and in a panel of breast cancer cell lines. In addition, Kaplan Meyer analyses revealed QSOX1 as a significant predictive marker for both relapse and poor overall survival in Luminal B tumors, but not in other intrinsic subtypes. To investigate malignant cell mechanisms in which QSOX1 might play a key role, we suppressed QSOX1 protein expression using short hairpin (sh) RNA in ER+ MCF7 and ER− BT549 breast cancer cell lines. Suppression of QSOX1 protein dramatically slowed cell proliferation but did not significantly effect apoptosis or cell cycle regulation. Inhibition of QSOX1 did however dramatically inhibit MCF7 and BT549 breast tumor cells from invading through Matrigel in a modified Boyden chamber assay. Inhibition of invasion could be rescued by the exogenous addition of recombinant QSOX1. Gelatin zymography indicated that QSOX1 plays an important role in activation of MMP-9 a key mediator of breast cancer invasive behavior. Taken together, our results suggest that QSOX1 is a novel biomarker for risk of relapse and poor survival in Luminal B breast cancer, and has a pro-invasive role in malignant progression through post-translational activation of MMP-9.

External Cavity Lasers Composed of Higher Order Gratings and SLDs Integrated on PLC Platform (2007)

Very compact 4-channel 200-GHz-spacing external cavity lasers (ECLs) were fabricated by hybrid integration of reflection gratings and superluminescent laser diodes on a planar lightwave circuit chip. The fifth-order gratings as reflection gratings were formed using a conventional contact-mask photo-lithography process to achieve low-cost fabrication. The lasing wavelength of the fabricated ECLs matched the ITU grid with an accuracy of ×0.1 nm, and optical powers were more than 0.4 mW at the injection current of 80 mA for all channels. The ECLs showed single mode operations with more than 30 dB side lobe suppression.

Chimeric Mice with Humanized Liver: Tools for the Study of Drug Metabolism, Excretion, and Toxicity (2010)

Recent developments in animal models have allowed the creation of mice with genetic alterations that cause hepatocyte damage that results, over time, in the loss of native hepatocytes. If donor, human hepatocytes are transplanted into these animals, they repopulate the host liver, frequently replacing over 70% of the native liver with human cells. Immunodeficient mice that overexpress urokinase-type plasminogen activator (uPA) and, alternatively, with a knockout of the fumarylacetoacetate hydrolase (Fah) genes are the two most common mouse models for these studies. These mice are called chimeric or "humanized" because the liver is now partially repopulated with human cells. In this report we will review the published work with respect to Phase I and Phase II metabolic pathways and the expression of hepatic transport proteins. While the studies are still at the descriptive stage, it is already clear that some humanized mice display high levels of repopulation with human hepatocytes, express basal and inducible human CYP450 genes, and human conjugation and hepatic transport pathways. When the strengths and weaknesses of these humanized mouse models are fully understood, they will likely be quite valuable for investigations of human liver-mediated metabolism and excretion of drugs and xenobiotics, drug-drug interactions, and for short- and long-term investigation of the toxicity of drugs or chemicals with significant human exposure.
High-quality networked terrain rendering from compressed bitstreams (2007)

We describe a compressed multiresolution representation and a client-server architecture for supporting interactive high quality remote visualization of very large textured planar and spherical terrains. Our approach incrementally updates a chunked level-of-detail BDAM hierarchy by using precomputed wavelet coefficient matrices decoded from a compressed bitstream originating from a thin server. The structure combines the aggressive compression rates of wavelet-based image representations with the ability to ensure overall geometric continuity for variable resolution views of planar and spherical terrains with no need for run-time stitching. The efficiency of the approach is demonstrated on a large scale interactive remote visualization of global and local terrains on ADSL networks. A library implementing an early version of this work has been incorporated into a widely distributed geo-viewing system with tens of thousands of clients.
An Algorithmic and Systematic Approach for Improving Robustness of TOA-Based Localization (2013)

Indoor localization using Time-of-Arrival (TOA) of ultrasound is accurate, but remarkable errors may occur occasionally due to effects by indoor environment issues, such as when ultrasound propagates in Non-Line-Of-Sight (NLOS) paths, or synchronization signal is interfered by background signals. This paper presents an algorithmic and systematic approach to address these issues to improve robustness of ultrasound TOA positioning. We firstly show from an optimization point of view that NLOS detection problem is NP-hard. We propose a novel clustering and filtering (COFFEE) algorithm to conduct density-based clustering iteratively on a bipartite graph model, which enables accurate, robust positioning and efficient NLOS outlier detection. Then, we develop a systematic method to address the robust time synchronization problem, which is called first-falling-edge time synchronization. It guarantees robust time synchronization even in severe interference environments. Both the COFFEE algorithm and the robust synchronization scheme are developed and implemented in a ultrasound positioning prototype called Dragon. Extensively simulations and experiments in Dragon show that the proposed methodologies outperform the robustness performances of the state-of-the-art methods, which demonstrate great improvements in various interference scenarios.
Practical and Highly Selective Sulfur Ylide Mediated Asymmetric Epoxidations and Aziridinations Using an Inexpensive, Readily Available Chiral Sulfide. Applications to the Synthesis of Quinine and Quinidine (2010)

Heating one of the most abundant naturally occurring inorganic chemicals (elemental sulfur) with one of the most readily available homochiral molecules (limonene) gives a one-step synthesis of a chiral sulfide which exhibits outstanding selectivities in sulfur ylide mediated asymmetric epoxidations and aziridinations. In particular reactions of benzyl and allylic sulfonium salts with both aromatic and aliphatic aldehydes gave epoxides with perfect enantioselectivities and the highest diastereoselectivities reported to date. In addition reactions with imines gave aziridines again with the highest enantioselectivities and diastereoselectivities reported to date. The reactions are scaleable, and the sulfide can be reisolated in high yield. The epoxidation has been used as the key step in a convergent and stereoselective synthesis of each of the diastereoisomers of the cinchona alkaloids, quinine and quinidine.
Influence of turmeric and curcumin on growth, blood constituents and serum enzymes in rats. (1982)

When rats were given turmeric (Curcuma longa) in amounts normally taken by man or in amounts 1.25 to 125 times those, there was no adverse effect on growth, food efficiency ratio, erythrocyte count, leucocyte count, differential counts or on haemoglobin, total serum protein or serum albumin, globulin, aminotransferase and alkaline phosphatase.
