A Novel Approach Toward Fabrication of High Performance Thin Film Composite Polyamide Membranes (2016)

A practical method is reported to enhance water permeability of thin film composite (TFC) polyamide (PA) membranes by decreasing the thickness of the selective PA layer. The composite membranes were prepared by interfacial polymerization (IP) reaction between meta-phenylene diamine (MPD)-aqueous and trimesoyl chloride (TMC)-organic solvents at the surface of polyethersulfone (PES) microporous support. Several PA TFC membranes were prepared at different temperatures of the organic solution ranging from -20 °C to 50 °C. The physico-chemical and morphological properties of the synthesized membranes were carefully characterized using serval analytical techniques. The results confirmed that the TFC membranes, synthesized at sub-zero temperatures of organic solution, had thinner and smoother PA layer with a greater degree of cross-linking and wettability compared to the PA films prepared at 50 °C. We demonstrated that reducing the temperature of organic solution effectively decreased the thickness of the PA active layer and thus enhanced water permeation through the membranes. The most water permeable membrane was prepared at -20 °C and exhibited nine times higher water flux compared to the membrane synthesized at room temperature. The method proposed in this report can be effectively applied for energy- and cost-efficient development of high performance nanofiltration and reverse osmosis membranes.

A phase I multiple dose, dose escalation study of cG250 monoclonal antibody in patients with advanced renal cell carcinoma. (2007)

The chimeric monoclonal antibody cG250 recognises the G250/CAIX/MN antigen found on 95% of clear cell renal cell carcinomas (RCCs). We performed a phase I clinical trial to evaluate the safety, blood pharmacokinetics (PK), and biodistribution of repeated doses of cG250. The primary endpoint was toxicity. Secondary endpoints were cG250 biodistribution and PK; measurement of human anti-chimeric-antibodies (HACA); and tumour response rates. Eligible patients had unresectable or metastatic clear cell RCC. Doses of 5, 10, 25, or 50 mg/m(2) were given weekly by intravenous infusion for six weeks. Three patients were treated at each dose level. Trace (131)I-labelled cG250 was administered on weeks 1 and 5. Thirteen patients participated and were evaluable. One patient developed brain metastases and was replaced. No grade 3 or 4 toxicities and no dose-limiting toxicity occurred. One patient died due to progressive disease within 30 days of receiving the study drug. One patient developed HACA during the second six-week cycle. PK analysis showed mean whole body and blood alpha and beta half-lives of cG250 of 18.99 +/- 6.84 and 180.19 +/- 86.68 hours, respectively. All patients had cG250 tumour localization by gamma camera imaging in week 1 and 5. One patient had a complete response, nine patients had stable disease, and three had progressive disease. One patient received 11 six-week cycles of treatment with no toxicity or HACA. In conclusion, repeated intravenous doses of up to 50 mg/m(2) of cG250 are safe. Furthermore cG250 has a long half-life and targets clear cell RCC effectively.
Group-Sensitive Triplet Embedding for Vehicle Reidentification (2018)

The widespread use of surveillance cameras toward smart and safe cities poses the critical but challenging problem of vehicle reidentification (Re-ID). The state-of-the-art research work performed vehicle Re-ID relying on deep metric learning with a triplet network. However, most existing methods basically ignore the impact of intraclass variance-incorporated embedding on the performance of vehicle reidentification, in which robust fine-grained features for large-scale vehicle Re-ID have not been fully studied. In this paper, we propose a deep metric learning method, group-sensitive-triplet embedding (GS-TRE), to recognize and retrieve vehicles, in which intraclass variance is elegantly modeled by incorporating an intermediate representation “group” between samples and each individual vehicle in the triplet network learning. To capture the intraclass variance attributes of each individual vehicle, we utilize an online grouping method to partition samples within each vehicle ID into a few groups, and build up the triplet samples at multiple granularities across different vehicle IDs as well as different groups within the same vehicle ID to learn fine-grained features. In particular, we construct a large-scale vehicle database “PKU-Vehicle,” consisting of 10 million vehicle images captured by different surveillance cameras in several cities, to evaluate the vehicle Re-ID performance in real-world video surveillance applications. Extensive experiments over benchmark datasets VehicleID, VeRI, and CompCar have shown that the proposed GS-TRE significantly outperforms the state-of-the-art approaches for vehicle Re-ID.

The objective of this paper is to establish understanding of the single/multimode oscillator circuits used in combiners. A model is developed with emphasis on the selection and realization of the input/output coefficients, optimum stabilizing and output loads, equalizing network synthesis, and other cogent features. The application of this theory to the highly successful and efficient design of J-band pulsed oscillators will be discussed.

Measurements of Planar Metal–Dielectric Structures Using Split-Post Dielectric Resonators (2010)

Split-post dielectric resonators were used for the measurement of the complex permittivity and the complex permeability of planar, uniaxialy anisotropic, low- and medium-loss metamaterials at microwave frequencies. Several metamaterials with different metal patterns deposited on dielectric substrates by plasma deposition were investigated, including edge-coupled and broadside-coupled split-rings and circles. It has been shown that, depending on the type of metal pattern and their surface resistance, the metamaterials may exhibit various magnetic and dielectric properties. Several small metamaterial samples were scanned in the cavity electromagnetic field by moving them inside the split-post dielectric resonator. This allowed us to identify loss mechanisms in the samples and to distinguish between their electric and magnetic properties. Our measurements were confirmed by modeling the transmission/reflection characteristics of virtual waveguides containing real metamaterial samples and homogenous samples with the same effective electromagnetic properties as those obtained from the split-post dielectric resonator method using a finite-difference time-domain electromagnetic simulator software package.
Cascaded Multi-view Canonical Correlation (CaMCCo) for Early Diagnosis of Alzheimer’s Disease via Fusion of Clinical, Imaging and Omic Features (2017)

The introduction of mild cognitive impairment (MCI) as a diagnostic category adds to the challenges of diagnosing Alzheimer's Disease (AD). No single marker has been proven to accurately categorize patients into their respective diagnostic groups. Thus, previous studies have attempted to develop fused predictors of AD and MCI. These studies have two main limitations. Most do not simultaneously consider all diagnostic categories and provide suboptimal fused representations using the same set of modalities for prediction of all classes. In this work, we present a combined framework, cascaded multiview canonical correlation (CaMCCo), for fusion and cascaded classification that incorporates all diagnostic categories and optimizes classification by selectively combining a subset of modalities at each level of the cascade. CaMCCo is evaluated on a data cohort comprising 149 patients for whom neurophysiological, neuroimaging, proteomic and genomic data were available. Results suggest that fusion of select modalities for each classification task outperforms (mean AUC = 0.92) fusion of all modalities (mean AUC = 0.54) and individual modalities (mean AUC = 0.90, 0.53, 0.71, 0.73, 0.62, 0.68). In addition, CaMCCo outperforms all other multi-class classification methods for MCI prediction (PPV: 0.80 vs. 0.67, 0.63).
Pipelining the HEVC decoder on ZedBoard plateform (2016)

For different applications like high quality Internet video, mobile video or digital TV, efficient coding of video signals is required to meet technical constraints as bandwidth, latency or execution time. To cope with these constraints and the growing demand in terms of resolution and quality as HD, Quad-HD and UHD videos, more efficient coding is required. For that, the h.265 HEVC (High Efficiency Video Coding) is developed by JCT-VC to substitute to MPEG-2, MPEG-4 and h.264 codecs.
Preparation of Congested Thiophenes Carrying Bulky Substituents on the 3- and 4-Positions and Their Conversion to the Benzene Derivatives (1998)

Highly congested thiophenes, 3,4-di-tert-butyl-, 3,4-di(1-adamantyl)-, 3,4-dineopentyl-, and 3-(1-adamantyl)-4-tert-butylthiophenes (4a−d), were prepared in satisfactory overall yields by intramolecular reductive coupling of 3-thiapentane-1,5-diones (1a−d) followed by acid-catalyzed dehydration of the resulting thiolane-3,4-diols (2a−d). Experimental procedures of this thiophene synthesis are fully described. Oxidation of the thiophenes 4a−d with m-CPBA gave the corresponding thiophene 1,1-dioxides 13a−d in good yields. The Diels−Alder reactions of 13a−d with phenyl vinyl sulfone gave o-di-tert-butyl-, o-di(1-adamantyl)-, o-dineopentyl-, and o-(1-adamantyl)-tert-butylbenzenes (17a−d) directly in high yields with loss of benzenesulfinic acid and sulfur dioxide. The dioxides 13a−d also underwent Diels−Alder reactions with alkynic dienophiles to give the corresponding benzene derivatives carrying two bulky substituents on adjacent positions. Pyridazines 25b,c, carrying bulky substituents on the 4- and 5-positions, were also synthesized through Diels−Alder reaction of 13b,c with PTAD. Dimethylation of the 2- and 5-positions of 13a−d was attained by treatment with strong bases followed by reactions with methyl iodide. The resulting tetrasubstituted thiophene 1,1-dioxides 14a−d reacted with DMAD to give highly congested hexasubstituted benzene derivatives 15a−d in good yields. Finally, structural features of the congested molecules are discussed on the basis of NMR analyses. Typically, the barriers to rotation (ΔH⧧) about the benzene to the bulky substituents of 15a,c,d were determined to be 8.59, 15.3, and 7.40 kcal/mol, respectively, by NMR total line-shape analysis.
Mesoionic oxatriazole derivatives--a new group of NO-donors. (1995)

A number of new 3-aryl-1,2,3,4-oxatriazole-5-imine derivatives (GEA Compounds--GEAC) were synthetized. GEAC are NO-releasers as evidenced by direct measurement of NO in headspace/NO-analyzer, by cooxygenation of oxyhaemoglobin to methaemoglobin in the Werringloer's test and by generation of nitrite in the Griess' reaction. During the release of NO from GEAC the consumption of O2 could be detected only when high concentrations of GEAC were used. The mechanism of release of NO from molecules of GEAC still remains hypothetical. Some of GEAC were found to remain stable for long periods of time, even at 37 degrees C. Both mutagenic properties and the pharmacodynamic profile of GEAC can be controlled by a mindful choosing of appropriate substituents.
Numerical Analysis for the Internal Flow of Thermal Vapor Compressor with real gas equation of state (2011)

열압축기는 고압 증기를 이용하여 저압 증기를 중간압으로 이송하는 일종의 이젝터이다. 이젝터에 대한 기존의 수치해석 연구는 대부분 작동유체를 이상기체로 취급하고 있으나 상변화가 발생하는 경우 이상기체 거동에서 크게 벗어날 수 있다. 따라서 본 연구에서는 이상기체 상태방정식 대신 Redlich-Kwong 방정식을 적용하여 열압축기 내부 유동을 수치 해석하였고, realizable k-ε 모델과 SST k-ω 모델을 비교한 결과 SST k-ω 모델이 shock diamond 패턴과 박리 및 난류경계층을 잘 예측하는 것을 확인할 수 있었다. 또한 실제기체 상태방정식을 사용한 경우가 이상기체 상태방정식을 사용한 경우에 비해 상대적으로 디퓨저 입구 부분과 디퓨저 목부분에서 에너지 손실이 많은 것을 알 수 있었으며, 디퓨저 출구부분에서 shock train에 의한 압력상승은 상대적으로 적으나 pseudo shock에 의한 압력상승은 동일한 것으로 확인되었다.
HLA‐class I expression in gastric cancer (2008)

Our data may suggest that loss of HLA-class I in gastric cancer did not directly reflect immunological escape from tumor antigen-specific cytotoxic T lymphocytes, unlike in other cancers.

DNA methylation alterations in urothelial carcinoma (2006)

In urothelial cancer, hypermethylation of specific genes and genome-wide hypomethylation, reflected in decreased methylation of LINE-1 retrotransposons, have both been reported, but were never investigated in the same specimens. We analyzed hypermethylation of six genes by methylation-specific PCR and LINE-1 hypomethylation by Southern blotting in 96 carcinoma tissues. Hypermethylation frequencies were: SFRP1 (55%), APC (45%), RASSF1A (35%), DAPK1 (29%), RARB2 (19%), and CDKN2A (2%). Three groups of cancers could be discerned, with escalating hypermethylation. Hypermethylation increased with tumor stage, particularly at the transition to invasive cancers, and RARB2 hypermethylation was indicative of lymph node involvement. A comparison to a previous study on prostate cancer using the same techniques suggests that hypermethylation in urothelial carcinoma occurs in a random rather than coordinated manner. LINE-1 hypomethylation was present in 90% of specimens, largely independent of hypermethylation. Lack of hypomethylation indicated a significantly better clinical prognosis. Bisulfite sequencing of SFRP1 demonstrated dense or patchy hypermethylation in tumor tissues that likely accounts for discrepant reported frequencies. In urothelial carcinoma cell lines, the same genes as in tissues were frequently hypermethylated. SFRP1 hypermethylation was concordant with lack of expression. 5-Aza-deoxycytidine induced its reexpression in some lines, whereas additional treatment with a histone deacetylase inhibitor was required in others. Thus, epigenetic SFRP1 inactivation occurs in a graduated manner. In conclusion, markers of genome-wide hypomethylation seem optimally suited for urothelial carcinoma detection, whereas combinations of hypermethylation and hypomethylation assays hold promise for classification.
An open system for transparent firewall authentication and user traffic identification within corporate intranets (2008)

Classical firewalls provide network security by matching a network flow's 5-tuple information against user defined packet filters loaded into memory. In today's dynamic network environments where threats can be both outside and inside a network, it is not sufficient to simply identify the originator of a data packet by a source address and port pair. It is necessary to identify the user or entity responsible for the transmission.
Broadly tunable metal halide perovskites for solid-state light-emission applications (2017)

The past two years have witnessed heightened interest in metal-halide perovskites as promising optoelectronic materials for solid-state light emitting applications beyond photovoltaics. Metal-halide perovskites are low-cost solution-processable materials with excellent intrinsic properties such as broad tunability of bandgap, defect tolerance, high photoluminescence quantum efficiency and high emission color purity (narrow full-width at half maximum). In this review, the photophysical properties of hybrid perovskites, which relates with light-emission, such as broad tunability, nature of the recombination processes and quantum efficiency are examined. The prospects of hybrid perovskite light-emitting diodes and lasers, and their key challenges are also discussed.
Pulsed photothermal deflection and diffraction effects: numerical modeling based on Fresnel diffraction theory (1999)

We present a comprehensive theoretical model suitable for treating the effect of pulsed collinear photothermal deflection spectros- copy (PDS). The work is an extension of the theoretical model previously developed for the mirage effect, which can take into account both pho- tothermal deflection and photothermal diffraction effects based on the Fresnel diffraction theory. With the diffraction model, both the collinear PDS and the photothermal lensing spectroscopy techniques can be treated in a unified manner. The model provides a detailed analysis of the laser-induced optical diffraction effect and can be used to optimize experimental parameters. The modeled results are presented in detail, with an emphasis on the advantages of using a near-field detection scheme for achieving the best sensitivity to local temperature change and better experimental stability against environmental noise. © 1999 Society of Photo-Optical Instrumentation Engineers.

Acceleration-Deceleration Sport-Related Concussion: The Gravity of It All. (2001)

OBJECTIVE: To discuss a newtonian physics model for understanding and calculating acceleration-deceleration forces found in sport-related cerebral concussions and to describe potential applications of this formula, including (1) an attempt to measure the forces applied to the brain during acceleration-deceleration injuries, (2) a method of accruing objective data regarding these forces, and (3) use of these data to predict functional outcome, such as neurocognitive status, recovery curves, and return to play. BACKGROUND: Mild concussion in sports has gained considerable attention in the last decade. Athletic trainers and team physicians have attempted to limit negative outcomes by gaining a better understanding of the mechanisms and severity of mild head injuries and by developing meaningful return-to-play criteria. Mild head injury in sports has become an even greater area of focus and concern, given the negative neurobehavioral outcomes experienced by several recent high-profile professional athletes who sustained repeated concussions. Applying the principles of physics to characterize injury types, injury severity, and outcomes may further our development of better concussion management techniques and prevention strategies. DESCRIPTION: We describe the search for models to explain neuronal injury secondary to concussion and provide an exploratory method for quantifying acceleration-deceleration forces and their relationship to severity of mild head injury. Implications for injury prevention and reduction of morbidity are also considered.
An Intelligent Versatile Model-Based Trajectory-Optimized Active Gate Driver for Silicon Carbide Devices (2019)

Using silicon carbide (SiC) power devices can potentially improve the efficiency of a power electronic system, but it may also introduce severe electromagnetic interference (EMI) problems due to the fast switching speed. The conventional gate driver cannot provide the flexibility to adjust the switching speed of SiC dynamically. To address this issue, an intelligent versatile active gate driver (AGD) is proposed to achieve optimized switching trajectory for power devices. The proposed AGD has five operation modes, i.e., faster/normal/slower the turn-on process and slower/normal turn-off process. The availability of multiple operation modes offers extra freedom to improve the switching performance and enable it to be versatile across various systems. The proposed AGD can provide more switching speed adjustment resolution than the other AGDs allowing for fine tuning of the switching speed of SiC power devices. In addition, a novel modelbased trajectory optimization strategy is proposed to determine the optimal gate driver output voltage by trading the EMI noise against the switching energy losses. The functionalities of the multi-level AGD are validated with the experimental results. The hardware design consideration is also given for the product commercialization purpose.
Mild Hypothermia Inhibits Systemic and Cerebral Complement Activation in a Swine Model of Cardiac Arrest (2015)

Complement activation has been implicated in ischemia/reperfusion injury. This study aimed to determine whether mild hypothermia (HT) inhibits systemic and cerebral complement activation after resuscitation from cardiac arrest. Sixteen minipigs resuscitated from 8 minutes of untreated ventricular fibrillation were randomized into two groups: HT group ( n = 8), treated with HT (33 °C) for 12 hours; and normothermia group ( n = 8), treated similarly as HT group except for cooling. Blood samples were collected at baseline and 0.5, 6, 12, and 24 hours after return of spontaneous circulation (ROSC). The brain cortex was harvested 24 hours after ROSC. Complement and pro-inflammatory markers were detected using enzyme-linked immunosorbent assay. Neurologic deficit scores were evaluated 24 hours after ROSC. C1q, Bb, mannose-binding lectin (MBL), C3b, C3a, C5a, interleukin-6, and tumor necrosis factor- α levels were significantly increased under normothermia within 24 hours after ROSC. However, these increases were significantly reduced by HT. Hypothermia decreased brain C1q, MBL, C3b, and C5a contents 24 hours after ROSC. Hypothermic pigs had a better neurologic outcome than normothermic pigs. In conclusion, complement is activated through classic, alternative, and MBL pathways after ROSC. Hypothermia inhibits systemic and cerebral complement activation, which may provide an additional mechanism of cerebral protection.
