A Proposal of the Photograph Estimation Technique by Using Infrared Rays (2004)

In this paper we propose a new automatic identification system. In our system, a user’s face is captured by a camera in order to identify him/her. By using an illumination difference image which is made of light coming from the right and left sides, our system can distinguish between a real person and a photograph. We describe an algorithm that detects whether the object facing the camera is planar(in the case of a photograph) or not(in the case of a real person). We propose a new technique for performing person-photograph distinction by using the surface direction image features.
Phenolic problems solved with hydrogen peroxide oxidation (1978)

Major industrial sources of phenolic waste discharges are: insulation fiberglass manufacturing, petroleum refineries, smelting and slag operations, organic products manufacture, synthetic resin manufacture, textile mills, steel-making, paint stripping, plywood, hardboard, and wood preserving. Phenolic discharges create problems in three areas: toxicity to marine life, taste and odor disturbances, and oxygen depletion of the receiving water. Methods for analyzing phenols are described. Metal catalyzed hydrogen peroxide is evaluated as an oxidant for the destruction of phenols. H2O2 treatment of phenols is shown to be commercially useful in batch treatment of phenolic wastes, for emergency backup to other phenolic treatment systems, and for polishing when discharge requirements are particularly stringent.

A fault-tolerant and congestion-aware routing algorithm for Networks-on-Chip (2010)

This paper presents a fault-tolerant routing algorithm for mesh-based Networks-on-Chip (NoC) with faulty links. It is a distributed, adaptive and congestion-aware routing algorithm where only two virtual channels are used for both adaptiveness and fault-tolerance. The proposed routing method has a multilevel fault-tolerance capability and therefore it is capable to tolerate more faulty links in more complicated faulty situations with additional hardware costs. The network performance, fault-tolerance capability and hardware overhead are evaluated through appropriate simulations. The experimental results show that the overall reliability of a Network-on-Chip is significantly enhanced against multiple link failures or partially faulty routers with only a small hardware overhead.
Performance driven VLSI system design for low energy wireless communications. (2000)

The advent of mobile wireless communications has generated increased demand for long lasting portable device operation, and consequently, system power dissipation has become an important design metric. This dissertation presents a design methodology for reducing the power consumption of several critical aspects of wireless communication system while achieving a desired level of performance. In particular, the design methodology focuses on the architectural and algorithmic optimization of synchronization techniques and decoding algorithms. First, a low-power multiplier design methodology for DSP and communication system applications is proposed. Then, the front-end digital components such as a matched filter and a fast Fourier transform, which are integral part of the demodulation and synchronization, are optimized for low-power. Also, a low-complexity synchronization technique for a hybrid spread-spectrum system is developed and analyzed which supports frequency hopping and variable spreading gain transmission. In addition, an efficient synchronization scheme is developed with low-complexity physical realization for multi-carrier spread-spectrum system. This dissertation also discussed the importance of channel coding and presented a low-complexity architecture and its low-power VLSI implementation for a turbo-code. Finally, a system level power optimization method is presented where the selection of algorithms and choice of accuracy are determined to minimize the overall power dissipation through power-performance tradeoff analysis.
Antibody to Chlamydial hsp60 Predicts an Increased Risk for Chlamydial Pelvic Inflammatory Disease (1997)

To determine whether serum antibody to Chlamydia trachomatis antigens alters the risk of C. trachomatis pelvic inflammatory disease (PID), 280 female sex workers were prospectively evaluated over a 33-month period for incident C. trachomatis and Neisseria gonorrhoeae cervical infection and for clinical PID. At enrollment, women were tested for antibody to C. trachomatis elementary bodies by an indirect microimmunofluorescence assay and to recombinant chlamydial hsp60 (Chsp60) by an ELISA format. At each follow-up visit, women were tested for cervical chlamydial and gonococcal infection and were identified as having clinical PID if they complained of lower abdominal pain and were found to have uterine and adnexal tenderness on pelvic examination. The data demonstrate that antibody to Chsp60 predicts a 2- to 3-fold increased risk for C. trachomatis PID.
Arabidopsis COP1 protein specifically interacts in vitro with a cytoskeleton-associated protein, CIP1. (1995)

Arabidopsis COP1 acts inside the nucleus to suppress photomorphogenic cellular development, and light inactivation of COP1 may involve a specific control of its nuclear activity in hypocotyls and cotyledons, but not in roots, of developing seedlings. To understand the molecular mechanisms of COP1 action during light-mediated development, we initiated a screen for Arabidopsis cDNAs encoding proteins which interact directly with COP1 in vitro as a step to identify the cellular components involved. We report here the isolation and characterization of a cDNA clone encoding a protein designated CIP1 (COP1-interactive protein 1). CIP1 is predominantly alpha-helical and most likely involved in coiled-coil formation. It interacts specifically with the putative coiled-coil region of COP1 in vitro. Further, CIP1 is encoded by a single gene in Arabidopsis, and its mRNA and protein levels are not regulated by light. Immunofluorescent labeling of CIP1 in Arabidopsis seedling protoplasts demonstrated that CIP1 is part of, or associated with, a cytoskeletal structure in hypocotyl and cotyledon cells, but not in roots. Our results are consistent with a possible role of CIP1 in mediating light control of COP1 nuclear activity by regulating its nucleocytoplasmic partitioning.
Octane: A New Heuristic for Pure 0–1 Programs (2001)

We propose a new heuristic for pure 0–1 programs, which finds feasible integer points by enumerating extended facets of the octahedron, the outer polar of the unit hypercube. We give efficient algorithms to carry out the enumeration, and we explain how our heuristic can be embedded in a branch-and-cut framework. Finally, we present computational results on a set of pure 0–1 programs taken from MIPLIB and other sources.
Antigen‐specific TIL therapy for melanoma: A flexible platform for personalized cancer immunotherapy (2016)

Tumor infiltrating lymphocyte (TIL) therapy has shown objective clinical response rates of 50% in stage IV melanoma patients in a number of clinical trials. Nevertheless, the majority of patients progress either directly upon therapy or after an initial period of tumor control. Recent data have shown that most TIL products that are used for therapy contain only low frequencies of T cells reactive against known melanoma-associated epitopes. Because of this, the development of a technology to create T-cell products that are enriched for reactivity against defined melanoma-associated antigens would seem valuable, both to evaluate the tumoricidal potential of T cells directed against different antigen classes and to potentially increase response rates. Here, we developed and validated a conditional MHC streptamer-based platform for the creation of TIL products with defined antigen reactivities. We have used this platform to successfully enrich both high-frequency (≥1%) and low-frequency (<1%) tumor-specific CD8(+) T-cell populations, and thereby created T-cell products with enhanced tumor recognition potential. Collectively, these data demonstrate that selection of antigen-specific T-cell populations can be used to create defined T-cell products for clinical use. This strategy thus forms a highly flexible platform for the development of antigen-specific cell products for personalized cancer immunotherapy.
ReconFS: a reconstructable file system on flash storage (2014)

Hierarchical namespaces (directory trees) in file systems are effective in indexing file system data. However, the update patterns of namespace metadata, such as intensive writeback and scattered small updates, exaggerate the writes to flash storage dramatically, which hurts both performance and endurance (i.e., limited program/erase cycles of flash memory) of the storage system.In this paper, we propose a reconstructable file system, ReconFS, to reduce namespace metadata writeback size while providing hierarchical namespace access. ReconFS decouples the volatile and persistent directory tree maintenance. Hierarchical namespace access is emulated with the volatile directory tree, and the consistency and persistence of the persistent directory tree are provided using two mechanisms in case of system failures. First, consistency is ensured by embedding an inverted index in each page, eliminating the writes of the pointers (indexing for directory tree). Second, persistence is guaranteed by compacting and logging the scattered small updates to the metadata persistence log, so as to reduce write size. The inverted indices and logs are used respectively to reconstruct the structure and the content of the directory tree on reconstruction. Experiments show that ReconFS provides up to 46.3% performance improvement and 27.1% write reduction compared to ext2, a file system with low metadata overhead.

This article describes the Television College established by the Thomson Foundation and the courses of training offered there for producers and engineers. The method of teaching producers is of particular interest as the formal lecture has been replaced by various forms of demonstration involving student participation and production exercises involving teamwork.
Targeted genome engineering in human induced pluripotent stem cells by penetrating TALENs (2013)

TAT-TALEN protein-mediated gene disruption was applicable in hiPSCs and represents a promising technique for gene knockout in stem cells. This new technique may advance the clinical application of TALEN technology.
Application of Non-contact Corona-Kelvin metrology for Characterization of Plasma Nitrided SiO[sub 2] (2007)

In this paper we demonstrate an application of the micro corona‐Kelvin metrology to monitoring of the electrical properties of silicon oxynitrides prepared with a plasma nitridation process currently used for advanced gate dielectrics. Key measurement parameters to be discussed are: dielectric capacitance equivalent thickness (CET), dielectric voltage in valence band tunneling range (VB), interface trapped charge (Qit) and flatband voltage. Negative polarity tunneling conditions are used as a measure of dielectric valence band. Taking advantage of the large valence band offset difference between Si3N4 and SiO2, we employ these tunneling measurements for very sensitive probing of the nitrogen content in SiON dielectrics.
Multi-feature shape regression for face alignment (2018)

For smart living applications, personal identification as well as behavior and emotion detection becomes more and more important in our daily life. For identity classification and facial expression detection, facial features extracted from face images are the most popular and low-cost information. The face shape in terms of landmarks estimated by a face alignment method can be used for many applications including virtual face animation and real face classification. In this paper, we propose a robust face alignment method based on the multi-feature shape regression (MSR), which is evolved from the explicit shape regression (ESR) proposed in Cao et al. (Int, Vis, 2014, 107:177–190, Comput). The proposed MSR face alignment method successfully utilizes color, gradient, and regional information to increase accuracy of landmark estimation. For face recognition algorithms, we further suggest a face warping algorithm, which can cooperate with any face alignment algorithm to adjust facial pose variations to improve their recognition performances. For performance evaluations, the proposed and the existing face alignment methods are compared on the face alignment database. Based on alignment-based face recognition concept, the face alignment methods with the proposed face warping method are tested on the face database. Simulation results verify that the proposed MSR face alignment method achieves better performances than the other existing face alignment methods.
Lithium Polyacrylate (LiPAA) as an Advanced Binder and a Passivating Agent for High‐Voltage Li‐Ion Batteries (2015)

Intensive studies of an advanced energy material are reported and lithium polyacrylate (LiPAA) is proven to be a surprisingly unique, multifunctional binder for high‐voltage Li‐ion batteries. The absence of effective passivation at the interface of high‐voltage cathodes in Li‐ion batteries may negatively affect their electrochemical performance, due to detrimental phenomena such as electrolyte solution oxidation and dissolution of transition metal cations. A strategy is introduced to build a stable cathode–electrolyte solution interphase for LiNi 0.5 Mn 1.5 O 4 (LNMO) spinel high‐voltage cathodes during the electrode fabrication process by simply using LiPAA as the cathode binder. LiPAA is a superb binder due to unique adhesion, cohesion, and wetting properties. It forms a uniform thin passivating film on LNMO and conducting carbon particles in composite cathodes and also compensates Li‐ion loss in full Li‐ion batteries by acting as an extra Li source. It is shown that these positive roles of LiPAA lead to a significant improvement in the electrochemical performance (e.g., cycle life, cell impedance, and rate capability) of LNMO/graphite battery prototypes, compared with that obtained using traditional polyvinylidene fluoride (PVdF) binder for LNMO cathodes. In addition, replacing PVdF with LiPAA binder for LNMO cathodes offers better adhesion, lower cost, and clear environmental advantages.

glTF streaming from 3D repo to X3DOM (2016)

As Web3D technology advances, the need for delivering real-time 3D content online has gained traction in the academic as well as commercial world. Various efforts have been made in creating a suitable transmission format for streaming of 3D assets over the Internet. Despite being accustomed to waiting for long periods of time for massive scenes to load in CAD editors, end users often expect an instant rendering on a web browser. An effective streaming transmission format, coupled with progressive encoding methods, is able to create a better interactive experience for the users. Most of the existing techniques are either domain specific, tying the users in on a particular rendering engine, or they are too general; resulting in extra processing at the application level. In this paper, we demonstrate a novel method of transmitting 3D assets in glTF format for high interoperability and scalability in 3D Repo. Firstly, we extend glTF with the ability to stream binary data buffers with a progressive encoding technique to increase performance and overall client interactivity. Next, we extend X3DOM for glTF support and introduce multipart optimization into glTF as a way of grouping multiple meshes together which significantly reduces the number of network requests as well as draw calls. Finally, we investigate memory management protocols and devise a novel GraphicsMemoryManager suitable for streaming on top of X3DOM in order to render models that otherwise would not fit available video memory.
Chitosan-Carboxymethylcellulose Hydrogels as Supports for cell Immobilization (1996)

Abstract The preparation of hydrogels from the polyelectrolyte complexation (PEC) of carboxymethylcellulose (CMC) and hydrogels from the complexation with an additional or simultaneous ionotropic gelation is reported. The reaction yield is high enough and depends strongly on the additional ionotropic gelation (IG). Infrared spectroscopy was used to confirm complexation between the carboxylic (in CMC) and amine (in chitosan) groups. The scanning electron microscope images show the formation of a fibrillar structure with characteristic pore sizes between 0.1 and 1 μm. The swelling capacity, Q, of PEC hydrogels is not high, but the Q value of hydrogels from PEC with an additional IG is high and depends strongly on the pH medium. These hydrogels are mechanically more stable than the PEC hydrogels; their mechanical strength is about 7 times higher than that of PEC hydrogels. The hydrogels were used to immobilize yeast cells with the cell density 1 × 109 cells/mL, about 100 times higher than that in the free-cell culture. Only the hydrogels with additional IG were stable enough for continuous fermentation over 10 days. These hydrogels proved to have higher affinity to substrate, which led to higher productivity than the ionotropic gel of CMC and aluminum ion.
The interaction of silver ions and hydrogen peroxide in the inactivation of E. coli: a preliminary evaluation of a new long acting residual drinking water disinfectant (1995)

The inactivation efficiencies of silver ions, hydrogen peroxide and their combination was studied as part of a performance evaluation of the combined disinfectant for drinking water applications. The major advantages of such combined disinfectant include, low toxicity of its components, long lasting residual effect and low disinfection by product formation. Specific strains of E. coli (E. coli-B (SR-9) and E. coli K-12) were used in this study as target microorganisms and the separate and combined inactivation efficiencies of silver and hydrogen peroxide were evaluated at different concentrations and exposure durations. Both, silver and hydrogen peroxide exhibited a significant inactivation performance even at concentrations that do not pose any health risk according to the EEC, WHO and the USEPA (the USEPA Maximum Contaminant Level (MCL) of silver is 90 ppb, and currently, there is no MCL for hydrogen peroxide but it is approved as a food additive in the USA). Combinations of 1:1000 silver:hydrogen peroxide (w) exhibited higher inactivation performance as compared with each of the disinfectants alone and in some cases a synergistic effect was observed, i.e., the combined disinfectant exhibited higher inactivation performance than the sum of the inactivation levels of the separate disinfectants. Thus, for example, one hour exposure to 30 ppb silver, 30 ppm hydrogen peroxide and their combination yielded 2.87, 0.65 and 5 logs of inactivation respectively. While the rate of inactivation shown by this combined disinfectant, now available commercially in a stabilized formulation is relatively slow, it may well hold promise as a secondary disinfectant providing long lasting residuals and biofilm control required for distribution systems. Its disinfection action may be similar to chloramines, the use of which has been recently outlawed in France and in Germany and which are now under careful scrutiny in other countries due to the formation of undesirable by-products.
Drug—DNA sequence‐dependent interactions analysed by electric linear dichroism (1992)

The interactions between 20 drugs and a variety of synthetic DNA polymers and natural DNAs were studied by electric linear dichroism (ELD). All compounds tested, including several clinically used antitumour agents, are thought to exert their biological activities mainly by virtue of their abilities to bind to DNA. The selected drugs include intercalating agents with fused and unfused aromatic structures and several groove binders. To examine the role of base composition and base sequence in the binding of these drugs to DNA, ELD experiments were carried out with natural DNAs of widely differing base composition as well as with polynucleotides containing defined alternating and non-alternating repeating sequences, poly(dA).poly(dT), poly(dA-dT).poly(dA-dT),poly(dG).poly(dC) and poly(dG-dC).poly(dG-dC). Among intercalating agents, actinomycin D was found to be by far the most GC-selective. GC selectivity was also observed with an amsacrine-4-carboxamide derivative and to a lesser extent with methylene blue. In contrast, the binding of amsacrine and 9-aminoacridine was practically unaffected by varying the GC content of the DNAs. Ethidium bromide, proflavine, mitoxantrone, daunomycin and an ellipticine derivative were found to bind best to alternating purine-pyrimidine sequences regardless of their nature. ELD measurements provided evidence for non-specific intercalation of amiloride. A significant AT selectivity was observed with hycanthone and lucanthone. The triphenyl methane dye methyl green was found to exhibit positive and negative dichroism signals at AT and GC sites, respectively, showing that the mode of binding of a drug can change markedly with the DNA base composition. Among minor groove binders, the N-methylpyrrole carboxamide-containing antibiotics netropsin and distamycin bound to DNA with very pronounced AT specificity, as expected. More interestingly the dye Hoechst 33258, berenil and a thiazole-containing lexitropsin elicited negative reduced dichroism in the presence of GC-rich DNA which is totally inconsistent with a groove binding process. We postulate that these three drugs share with the trypanocide 4',6-diamidino-2-phenylindole (DAPI) the property of intercalating at GC-rich sites and binding to the minor groove of DNA at other sites. Replacement of guanines by inosines (i.e., removal of the protruding exocyclic C-2 amino group of guanine) restored minor groove binding of DAPI, Hoechst 33258 and berenil. Thus there are several cases where the mode of binding to DNA is directly dependent on the base composition of the polymer. Consequently the ELD technique appears uniquely valuable as a means of investigating the possibility of sequence-dependent recognition of DNA by drugs.
