XML document versioning (2001)

Managing multiple versions of XML documents represents an important problem, because of many applications ranging from traditional ones, such as software configuration control, to new ones, such as link permanence of web documents. Research on managing multiversion XML documents seeks to provide efficient and robust techniques for (i) storing and retrieving, (ii) exchanging, and (iii) querying such documents. In this paper, we first show that traditional version control methods, such as RCS, and SCCS, fall short from satisfying these three requirements, and discuss alternative solutions. First, we enhance RCS with a temporal page clustering policy to achieve objective (i). Then, we discuss a reference-based versioning scheme that achieves both objectives (i) and (ii) and is also effective at supporting simple queries. The topic of supporting complex queries, including temporal ones, meshes with the burgeoning interest of database researchers in XML as a database description language, and in XML query languages. In this context, the XML versioning problems are akin to those of transaction time management for databases of objects and semistructured information. Nevertheless, the need to preserve the natural ordering of XML documents frequently requires different techniques.
On Improving Reliability of SRAM-Based Physically Unclonable Functions (2017)

Physically unclonable functions (PUFs) have been touted for their inherent resistance to invasive attacks and low cost in providing a hardware root of trust for various security applications. SRAM PUFs in particular are popular in industry for key/ID generation. Due to intrinsic process variations, SRAM cells, ideally, tend to have the same start-up behavior. SRAM PUFs exploit this start-up behavior. Unfortunately, not all SRAM cells exhibit reliable start-up behavior due to noise susceptibility. Hence, design enhancements are needed for improving reliability. Some of the proposed enhancements in literature include fuzzy extraction, error-correcting codes and voting mechanisms. All enhancements involve a trade-off between area/power/performance overhead and PUF reliability. This paper presents a design enhancement technique for reliability that improves upon previous solutions. We present simulation results to quantify improvement in SRAM PUF reliability and efficiency. The proposed technique is shown to generate a 128-bit key in ≤0.2 μ s at an area estimate of 4538 μ m 2 with error rate as low as 10 − 6 for intrinsic error probability of 15%.
A new video signal processor for high-end professional LaserVision CD video players (1988)

An integrated circuit (IC) is described that is designed to process the signal from the photodiode in a LaserVision or compact disk (CD) video player directly into a CVBS signal suitable for a color TV receiver. The bipolar IC requires about 45 mA from a 5 V supply and incorporates the following features: modulation transfer function (MTF) compensation, de-emphasis, dropout compensation, noise reduction, separation of signals for timing control, picture insertion, a data slicer, and a NTSC/PAL system selector.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>

Budding-like division of all-aqueous emulsion droplets modulated by networks of protein nanofibrils (2018)

Networks of natural protein nanofibrils, such as cytoskeletal filaments, control the shape and the division of cells, yet mimicking this functionality in a synthetic setting has proved challenging. Here, we demonstrate that artificial networks of protein nanofibrils can induce controlled deformation and division of all-aqueous emulsion droplets with budding-like morphologies. We show that this process is driven by the difference in the immersional wetting energy of the nanofibril network, and that both the size and the number of the daughter droplets formed during division can be controlled by modulating the fibril concentration and the chemical properties of the fibril network. Our results demonstrate a route for achieving biomimetic division with synthetic self-assembling fibrils and offer an engineered approach to regulate the morphology of protein gels.
Control of Single-Stage Single-Phase PV Inverter (2006)

In this paper the issue of control strategies for single-stage photovoltaic (PV) inverter is addressed. Two different current controllers (the classical proportional-integral (PI) and the novel proportional-resonant (PR) controllers) have been implemented and an experimental comparison between them has been made. A complete control structure for the singlephase PV system is also presented. The superiority of the PR controller is demonstrated with respect to the PI controller in terms of harmonic current rejection and the capability to remove the steady-state error without using the voltage feedforward (VFF). The control strategy was successfully tested on a real 1.5 kW PV inverter.
A theophylline responsive riboswitch based on helix slipping controls gene expression in vivo (2004)

Riboswitches are newly discovered regulatory elements which control a wide set of basic metabolic pathways. They consist solely of RNA, sense their ligand in a preformed binding pocket and perform a conformational switch in response to ligand binding resulting in altered gene expression. We have utilized the enormous potential of RNA for molecular sensing and conformational changes to develop novel molecular switches with predetermined structural transitions in response to the binding of a small molecule. To validate these in vivo, we exploit the distance-dependent inhibitory potential of secondary structure elements placed close to the bacterial ribosome binding site. We created a translational control element by combining the theophylline aptamer with a helical communication module for which a ligand-dependent one-nucleotide slipping mechanism had been proposed. This structural element was inserted at a position just interfering with translation in the non ligand-bound form. Addition of the ligand then shifts the inhibitory element to a distance which permits efficient translation. We present here a novel regulatory mechanism in the first rationally designed, in vivo active RNA switch. Its use of a slippage mechanism to control gene expression makes it different from natural riboswitches which are based on sequestration or antitermination.

Synthesis and Application of Two Reagents for the Introduction of Sulfhydryl Groups into Proteins (1983)

Two reagents are described which can be used for the introduction of sulfhydryl groups into proteins. Mercaptopropionylhydrazide modifies specifically periodate-oxidized N termini of proteins, provided that the N-terminal residue is serine or threonine. 3-(Phenyldithio)propionimidate introduces a disulfide bond at lysine residues of proteins. Reduction converts the disulfide into a sulfhydryl group. The imidate compound was found to react with a high specificity with only one lysine residue of ribosomal protein L7/L12.
Synthesis of a 2D nitrogen-rich π-conjugated microporous polymer for high performance lithium-ion batteries (2019)

Novel 2D graphene analogues with high conductivity are highly demanded as anode materials for lithium-ion batteries (LIBs). Here we report the preparation and characterization of a π-conjugated microporous polymer NGA-CMP with an experimental bandgap of 2.34 eV. Heated sample NGA-CMP400 is used for the first time as an anode material for LIBs. NGA-CMP400 achieves a high reversible capacity of 701 mA h g-1 at 1 A g-1 with extremely stable cycling performance over 500 cycles. The rational design of this kind of graphene-like 2D material with inherent porosity and enhanced electronic conductivity possesses important significance in carbon-based anode materials for LIBs.
Altered Pathogenesis of Severe Pneumovirus Infection in Response to Combined Antiviral and Specific Immunomodulatory Agents (2002)

We report here the responses of mice with symptomatic pneumovirus infection to combined antiviral and specific immunomodulatory agents. Mice infected with pneumonia virus of mice, a natural mouse pathogen that replicates the signs and symptoms of severe infection with respiratory syncytial virus (RSV), responded to the antiviral agent ribavirin when it was administered in the setting of endogenous (gene deletion) or exogenous (antibody-mediated) blockade of the MIP-1alpha proinflammatory signaling cascade. Although neither treatment is effective alone, together they offer a dramatic reduction in symptoms and pathology, the most impressive of which is a significant reduction in morbidity and mortality. The findings presented are consistent with the notion of unique and independent contributions of virus replication and ongoing inflammation to the pathogenesis of severe respiratory virus infection, and they provide the impetus for the study of this treatment regimen in RSV-infected humans.

Diagnostic Performance of Dengue Virus Envelope Domain III in Acute Dengue Infection (2019)

Dengue, one of the most prevalent illnesses caused by dengue viruses that are members of the genus <i>Flavivirus</i>, is a significant global health problem. However, similar clinical symptoms and high antigenic homologies with other Flaviviruses in the endemic area pose difficulties for differential diagnosis of dengue from other arbovirus infections. Here, we investigated four types of recombinant envelope protein domain III (DV-rED III) derived from four dengue virus (DENV) serotypes for diagnostic potential in detecting IgM in acute phase (mainly 2-3 days after onset of fever). Each independent DV-1, -3, and -4-rED III-ELISA showed less than 60% sensitivity, but the combined results of DV-1, -3, and -4-rED III-ELISA led to sensitivity of 81.82% (18/22) (95% CI, 59.72 to 94.81) and 100% specificity (46/46) (95% CI, 92.29 to 100.00) as each antigen compensated the other antigen-derived negative result. In conclusion, the independent combination of data derived from each recombinant antigen (DV1-, DV3-, and DV4-rED III) showed comparable efficacy for the detection of IgM in patients with acute-phase dengue infection.
PAPR Reduction for OFDM System with a Class of HNN (2006)

The PAPR issue in OFDM system can be formulated to a combinational optimization problem. This paper proposes a class of approaches to reduce the PAPR value of multi-carrier/OFDM system by solving this combinational optimization problem with some improved Hopfield neural networks (HNN) . Furthermore, the general theoretical framework of PAPR reduction based on all kinds of HNN is presented as well. By adopting new neural output function and random state disturbance, many kinds of HNN networks are implemented and used to solve this problem. By analyzing the PAPR reduction performance, we give some significative suggestion on PAPR issues based on HNN and verify the effectivity of HNN approaches. Simulation results show PAPR is improved greatly compared to the traditional PAPR reduction methods. The general improvement is about 3 dB. So it is a class of effective and practical algorithms for PAPR reduction in OFDM system
Point based animation of elastic, plastic and melting objects (2004)

We present a method for modeling and animating a wide spectrum of volumetric objects, with material properties anywhere in the range from stiff elastic to highly plastic. Both the volume and the surface representation are point based, which allows arbitrarily large deviations form the original shape. In contrast to previous point based elasticity in computer graphics, our physical model is derived from continuum mechanics, which allows the specification of common material properties such as Young's Modulus and Poisson's Ratio.

Evaluation of BacT/Alert 3D Liquid Culture System for Recovery of Mycobacteria from Clinical Specimens Using Sodium Dodecyl (Lauryl) Sulfate-NaOH Decontamination (2001)

A total of 52 mycobacterial isolates were recovered from 1,197 clinical specimens decontaminated by a sodium dodecyl (lauryl) sulfate (SDS)-NaOH protocol. Of these, 94% were recovered with the BacT/Alert 3D system (Organon Teknika, Durham, N.C.) and 79% were recovered on Löwenstein-Jensen (LJ) medium. Mean times to detection of organisms of the Mycobacterium tuberculosis complex (n = 47) were 22.8 days with LJ medium and 16.2 days with the system. The BacT/Alert 3D system is a rapid and efficient detection system which can be used with an SDS-NaOH decontamination procedure.
Differential expression of the pro-natriuretic peptide convertases corin and furin in experimental heart failure and atrial fibrosis (2012)

In heart failure (HF), the cardiac hormone natriuretic peptides (NPs) atrial (ANP), B-type (BNP), and C-type (CNP) play a key role to protect cardiac remodeling. The proprotein convertases corin and furin process their respective pro-NPs into active NPs. Here we define in a canine model of HF furin and corin gene and protein expression in normal and failing left atrium (LA) or ventricle (LV) testing the hypothesis that the NP proproteins convertases production is altered in experimental HF. Experimental canine HF was produced by rapid right ventricular pacing for 10 days. NPs, furin, and corin mRNA expression were determined by quantitative RT-PCR. Protein concentration or expression was determined by immunostaining, radioimmunoassay, or Western blot. Furin and corin proteins were present in normal canine LA and LV myocardium and vasculature and in smooth muscle cells. In normal canines, expression of NPs was dominant in the atrium compared with the ventricle. In experimental early stage HF characterized with marked atrial fibrosis, ANP, BNP, and CNP mRNA, and protein concentrations were higher in HF LA but not HF LV compared with normals. In LA, corin mRNA and protein expressions in HF were lower, whereas furin mRNA and protein expressions were higher than normals. NPs and furin expressions were augmented in the atrium in experimental early stage HF and, conversely, corin mRNA and protein expressions were decreased with atrial remodeling. Selective changes of these NP convertases may have significance in the regulation of pro-NP processing and atrial remodeling in early stage HF.

Transplanted Senescent Cells Induce an Osteoarthritis-Like Condition in Mice (2016)

Osteoarthritis (OA) is the leading form of arthritis in the elderly, causing pain, disability, and immobility. OA has been associated with accumulation of senescent cells in or near joints. However, evidence for a causal link between OA and cellular senescence is lacking. Here, we present a novel senescent cell transplantation model involving injection of small numbers of senescent or nonsenescent cells from the ear cartilage of luciferase-expressing mice into the knee joint area of wild-type mice. By using bioluminescence and 18FDG PET imaging, we could track the injected cells in vivo for more than 10 days. Transplanting senescent cells into the knee region caused leg pain, impaired mobility, and radiographic and histological changes suggestive of OA. Transplanting nonsenescent cells had less of these effects. Thus, senescent cells can induce an OA-like state and targeting senescent cells could be a promising strategy for treating OA.

Defucosylated Humanized Anti-CCR4 Monoclonal Antibody KW-0761 as a Novel Immunotherapeutic Agent for Adult T-cell Leukemia/Lymphoma (2010)

KW-0761 should be sufficiently active for therapeutic clinical application for ATLL. In addition, combination treatment strategies that augment natural killer cell activity should be promising for amplifying the effect of KW-0761. In the near future, the actual efficacy of KW-0761 will be established in pivotal clinical trials.
Transfer Printed P3HT/PCBM Photoactive Layers: From Material Intermixing to Device Characteristics (2016)

The fabrication of organic electronic devices involving complex stacks of solution-processable functional materials has proven challenging. Significant material intermixing often occurs as a result of cross-solubility and postdeposition treatments, rendering the realization of even the simplest bilayer architectures rather cumbersome. In this study we investigate the feasibility of a dry transfer printing process for producing abrupt bilayer organic photodiodes (OPDs) and the effect of thermal annealing on the integrity of the bilayer. The process involves the transfer of readily deposited thin films of poly(3-hexylthiophene-2,5-diyl) (P3HT) and [6,6]-phenyl C61 butyric acid methyl ester (PCBM) using a polydimethylsiloxane (PDMS) stamp. Fabricated structures are characterized by means of cross-sectional scanning electron microscopy (SEM), UV/vis absorption spectroscopy, and time-of-flight secondary ion mass spectrometry (TOF-SIMS). Joint consideration of all results unveils abrupt interfaces with no thermal treatment applied and significant material intermixing for samples annealed above 100 °C. The role of the thermally assisted intermixing in determining the performance of complete devices is evaluated through the comparison of J-V characteristics and external quantum efficiencies (EQEs) of identical photodiodes subject to different annealing conditions. It is shown that the performance of such devices approaches the one of bulk heterojunction photodiodes upon thermal annealing at 140 °C for 5 min. Our results demonstrate that transfer printing is a reliable and simple process for the realization of functional multilayers, paving the way for organic electronic devices incorporating complex stacks. It further contributes to a fundamental understanding of material composition within photoactive layers by elucidating the process of thermally assisted intermixing.
