Development of the new Cu alloy bearing for higher load and longer life of future diesel engines (1999)

Basic stick-slip tests and alternating load tests under conditions closer to real operating conditions were performed with the purpose of developing engine bearing materials adequate for longer service lives and the higher load of diesel engines. Obtained results showed that Cu-Sn-Ag alloy material performed better than conventional lead-bronze alloy and showed its load carrying capacity to be 120 MPa and its life to be 10 7 cycles. Also, bench tests performed by using a real engine showed that at a load carrying capacity of 80 MPa, Cu-Sn-Ag material had a life of more than 2.4 x 10 8 cycles and could meet the requirements for higher normal pressure and longer service lives of future diesel engines. The reason for this ability to withstand higher normal pressure and a higher resistance to seizure of the alloy was the formation of some compounds related to Sn, Ag, and S on the sliding surface, the prevention of the adhesion, and the transfer of bearing lining material to the shaft under higher normal pressure conditions.
<title>Picture management using person retrieval for consumer image collections</title> (2007)

In the last years the huge evolution of digital photography lead to an increasing interest in developing algorithms for indexing and classifying collections of digital images. This paper presents an automatic system for organizing and browsing through consumer digital image collections using the persons in the images as patterns. In order to implement such an automatic system we have to detect and classify the people in the images according to their similarities. For this we employ algorithms for face detection, face recognition and additional methods to cope with large variations that are usually present in consumer images. These additional methods includes using more than one type of classifiers for face recognition and also using additional information about the person characteristics extracted from other region than the face. This additional information will be more robust to factors that influence the accuracy of classical face recognition systems when working with consumer images. The proposed system was tested using a typical consumer image collection and practical applications using the system are presented in the end.
Atomizer (2004)

Ensuring the correctness of multithreaded programs is difficult, due to the potential for unexpected interactions between concurrent threads. Much previous work has focused on detecting race conditions, but the absence of race conditions does not by itself prevent undesired thread interactions. We focus on the more fundamental non-interference property of atomicity; a method is atomic if its execution is not affected by and does not interfere with concurrently-executing threads. Atomic methods can be understood according to their sequential semantics, which significantly simplifies (formal and informal) correctness arguments.This paper presents a dynamic analysis for detecting atomicity violations. This analysis combines ideas from both Lipton's theory of reduction and earlier dynamic race detectors. Experience with a prototype checker for multithreaded Java code demonstrates that this approach is effective for detecting errors due to unintended interactions between threads. In particular, our atomicity checker detects errors that would be missed by standard race detectors, and it produces fewer false alarms on benign races that do not cause atomicity violations. Our experimental results also indicate that the majority of methods in our benchmarks are atomic, supporting our hypothesis that atomicity is a standard methodology in multithreaded programming.
High efficiency low operating voltage polymer light-emitting diodes with aluminum cathode (2004)

By blending poly(ethylene glycol) (PEG) into an electroluminescence (EL) polymer, significantly enhanced EL efficiency in a polymer light-emitting diode (PLED) with aluminum electrode was achieved. An orange-color-emitting PLED with 10 wt % PEG blending achieved device efficiencies exceeding 2.6 cd/A for a wide range of bias voltage, which is more than two orders of magnitude higher than that of a similar PLED without the PEG blending. The enhanced efficiency was a result of the reduction of electron injection barrier height at the cathode–polymer interface. It is believed that interfacial interaction that is specific to Al plays an important role in the enhancement mechanism.
Repurposing Decoder-Transformer Language Models for Abstractive\n Summarization (2019)

Neural network models have shown excellent fluency and performance when\napplied to abstractive summarization. Many approaches to neural abstractive\nsummarization involve the introduction of significant inductive bias,\nexemplified through the use of components such as pointer-generator\narchitectures, coverage, and partially extractive procedures, designed to mimic\nthe process by which humans summarize documents. We show that it is possible to\nattain competitive performance by instead directly viewing summarization as a\nlanguage modeling problem and effectively leveraging transfer learning. We\nintroduce a simple procedure built upon decoder-transformers to obtain highly\ncompetitive ROUGE scores for summarization performance using a language\nmodeling loss alone, with no beam-search or other decoding-time optimization,\nand instead relying on efficient nucleus sampling and greedy decoding.\n
Particle size monitoring in dense suspension using ultrasound with an improved model accounting for low‐angle scattering (2010)

Abstract The inherent ability of ultrasonic wave to propagate in dense and opaque suspensions makes it a desirable method for online measurement of particle size distribution in industrial operations. The ability of ultrasonic attenuation spectroscopy to determine particle size distribution has been extended to dense suspensions of particles lying predominantly in the intermediate wave propagation regime at the measurement frequencies. This was achieved by accounting for the effect of detector size and shift in the frequency spectrum under dense conditions in the theoretical model and deconvolution algorithm, respectively. The proposed modifications enable the application of this technique in various industrial processes requiring in situ and real‐time measurement of particle size distribution such as crystallization, mineral processing and food processing. © 2010 American Institute of Chemical Engineers AIChE J, 2010
χ-Shaped Bis(areno)-1,4-dihydropyrrolo[3,2-<i>b</i>]pyrroles Generated by Oxidative Aromatic Coupling (2015)

A synthesis of dihydropyrrolo[3,2-b]pyrroles fused with two peripheral arenes or heterocyclic units has been realized through the concise route. These nearly planar compounds were prepared starting from assembling the central core via condensation of 2-aryl or 2-heteroarylbenzaldehydes with aromatic amines and diacetyl, followed by double intramolecular oxidative aromatic coupling. This two-step procedure afforded the desired products in overall yields of 5-36%, and it tolerates structural diversity of starting materials. All the final dyes exhibit strong blue fluorescence in solution.
The adsorption of water vapor on carbon fiber composite molecular sieve (1998)

Carbon Fiber Composite Molecular Sieve (CFCMS) is a porous adsorbent carbon material manufactured from isotropic pitch derived carbon fibers and a phenolic resin binder via a slurry molding process. The material is produced in the form of a monolith and can be activated in steam, CO{sub 2} or O{sub 2}, during which it develops high BET surface areas and micropore volumes. The material has a continuous carbon skeletal structure and is, therefore, electrically conductive. The passage of an electric current at low voltage allows for direct resistive heating of the carbon and thus provides an efficient method of desorbing adsorbed gases. This method of separating gases has been named electrical swing adsorption (ESA) and is analogous to thermal or pressure swing adsorption. Recently, the authors have examined the potential of CFCMS/ESA for the adsorption and separation of water vapor. Frequently, water vapor must be removed from a gas stream before separation and processing can occur. To assess the potential of CFCMS for water adsorption a series of CFCMS samples were manufactured and activated to relatively high burn-off. Half of each sample was treated at 200 C in flowing oxygen to increase the number of chemisorbed surface functional groups. The amount of water adsorbed has previously been shown to be controlled by the availability of surface functional groups (such as carboxylic acid) which act as active sites for the adsorption of water. Here the authors report the preliminary study of the moisture adsorption behavior of treated and untreated CFCMS samples.
Low-Frequency Synthetic Aperture Sonar System (2003)

An experimental synthetic aperture sonar system is developed, and a set of cruises is also conducted. The primary purpose of the system is to confirm the validity of the motion compensation technique, which combines the use of both the DPC algorithm and the motion sensor. The experiment clearly shows the effectiveness of this combination, resulting in the successful estimation of underwater motion errors and the formation of synthetic aperture images.
39.4: A Metal‐Based High‐Resonant‐Frequency Optical Scanner with a Moving‐Magnet Actuator for Non‐Resonant Large‐Angle Scanning (2011)

Abstract A metal based optical scanner for non‐resonant drive has been developed. A thin magnet, installed beneath a scan mirror, drives the mirror over +/−20 degrees of optical angle. The moving magnet actuator's large torque enables designing the torsion spring constant high for high resonant frequency, which makes laser projectors bright and optically efficient.
Development of autoantibodies against muscle-specific FHL1 in severe inflammatory myopathies (2015)

Mutations of the gene encoding four-and-a-half LIM domain 1 (FHL1) are the causative factor of several X-linked hereditary myopathies that are collectively termed FHL1-related myopathies. These disorders are characterized by severe muscle dysfunction and damage. Here, we have shown that patients with idiopathic inflammatory myopathies (IIMs) develop autoimmunity to FHL1, which is a muscle-specific protein. Anti-FHL1 autoantibodies were detected in 25% of IIM patients, while patients with other autoimmune diseases or muscular dystrophies were largely anti-FHL1 negative. Anti-FHL1 reactivity was predictive for muscle atrophy, dysphagia, pronounced muscle fiber damage, and vasculitis. FHL1 showed an altered expression pattern, with focal accumulation in the muscle fibers of autoantibody-positive patients compared with a homogeneous expression in anti-FHL1-negative patients and healthy controls. We determined that FHL1 is a target of the cytotoxic protease granzyme B, indicating that the generation of FHL1 fragments may initiate FHL1 autoimmunity. Moreover, immunization of myositis-prone mice with FHL1 aggravated muscle weakness and increased mortality, suggesting a direct link between anti-FHL1 responses and muscle damage. Together, our findings provide evidence that FHL1 may be involved in the pathogenesis not only of genetic FHL1-related myopathies but also of autoimmune IIM. Importantly, these results indicate that anti-FHL1 autoantibodies in peripheral blood have promising potential as a biomarker to identify a subset of severe IIM.
Quadrature product subcarrier modulation (QPSM) (1999)

Due to the limited availability of spectrum allocations for communications systems, it has become desirable to reuse existing spectrum by employing bandwidth efficient modulation methods to existing satellite communications systems. As the number of users of a given communication system increases, it often becomes necessary to augment the system with additional communication signals. One method that has been used to achieve this goal in Timing, Telemetry and Command (TT&C) links is conventional subcarrier phase modulation. In this work we present a new subcarrier modulation technique called Quadrature Product Subcarrier Modulation (QPSM) that enables the transmission of a quadrature multiplexed carrier modulation with single or multiple subcarrier signals in the same constant-envelope waveform. The general approach is applied to the addition of subcarrier signals to a quadrature multiplexed spread-spectrum system. The overall power efficiency is derived for each case under consideration. The modulation's spectral components are derived analytically and the analytical results are compared to results simulated using the Signal Processing WorkSystem simulation environment.
Chondroitin Sulfate Synthase-3 (2003)

Recently, it has become evident that chondroitin sulfate (CS) glycosyltransferases, which transfer glucuronic acid and/or N-acetylgalactosamine residues from each UDP-sugar to the nonreducing terminus of the CS chain, form a gene family. We report here a novel human gene (GenBank trade mark accession number AB086062) that possesses a sequence homologous with the human chondroitin sulfate synthase-1 (CSS1) gene, formerly known as chondroitin synthase. The full-length open reading frame consists of 882 amino acids and encodes a typical type II membrane protein. This enzyme contains a beta 3-glycosyltransferase motif and a beta 4-glycosyltransferase motif similar to that found in CSS1. Both the enzymes were expressed in COS-7 cells as soluble proteins, and their enzymatic natures were characterized. Both glucuronyltransferase and N-acetylgalactosaminyltransferase activities were observed when chondroitin, CS polymer, and their corresponding oligosaccharides were used as the acceptor substrates, but no polymerization reaction was observed as in the case of CSS1. The new enzyme was thus designated chondroitin sulfate synthase-3 (CSS3). However, the specific activity of CSS3 was much lower than that of CSS1. The reaction products were shown to have a GlcUA beta 1-3GalNAc linkage and a GalNAc beta 1-4GlcUA linkage in the nonreducing terminus of chondroitin resulting from glucuronyltransferase activity and N-acetylgalactosaminyltransferase activity, respectively. Quantitative real time PCR analysis revealed that the transcript level of CSS3 was much lower than that of CSS1, although it was ubiquitously expressed in various human tissues. These results indicate that CSS3 is a glycosyltransferase having both glucuronyltransferase and N-acetylgalactosaminyltransferase activities. It may make a contribution to CS biosynthesis that differs from that of CSS1.
New results on SNR estimation of MPSK modulated signals (2004)

Signal-to-noise ratio (SNR) is an important parameter in many receivers. In a previous letter B Li et al., (2002) we derived a maximum-likelihood amplitude estimator and obtained a low bias SNR estimation algorithm for a binary phase-shift keying (BPSK) modulated signal. We now extend the result and obtain a low bias SNR estimator for multiple phase-shift keying (MPSK) modulation. We compare our algorithm with others, such as a decision-directed approach. Simulations show that the new algorithm provides not only much lower bias and but also much smaller mean square error (MSE).
Cellular non-nonlinear network model of microbial fuel cell (2017)

A cellular non-linear network (CNN) is a uniform regular array of locally connected continuous-state machines, or nodes, which update their states simultaneously in discrete time. A microbial fuel cell (MFC) is an electro-chemical reactor using the metabolism of bacteria to drive an electrical current. In a CNN model of the MFC, each node takes a vector of states which represent geometrical characteristics of the cell, like the electrodes or impermeable borders, and quantify measurable properties like bacterial population, charges produced and hydrogen ions concentrations. The model allows the study of integral reaction of the MFC, including temporal outputs, to spatial disturbances of the bacterial population and supply of nutrients. The model can also be used to evaluate inhomogeneous configurations of bacterial populations attached on the electrode biofilms.
Elicitation of T Cell Responses to Histologically Unrelated Tumors by Immunization with the Novel Cancer-Testis Antigen, Brother of the Regulator of Imprinted Sites (2007)

Brother of the regulator of imprinted sites (BORIS) was previously described as a transcription factor for epigenetic reprogramming the expression of which is strictly confined to germ cells of adult testes but is aberrantly activated in the vast majority of neoplastic cells. Considering the critical role of BORIS in cancerogenesis and the fact that its expression pattern may preclude thymic tolerance, we generated DNA- and protein-based mouse BORIS antitumor vaccines using a non-DNA-binding version of the BORIS molecule. Clinical use of BORIS as a vaccine Ag would require that certain safety concerns be met. Specifically, administration of the functional BORIS protein would hypothetically pose a risk of BORIS accelerating the progression of cancer. To alleviate such safety concerns, we have developed vaccines based on the BORIS molecule lacking the DNA-binding zinc fingers domain. To enhance anti-BORIS cellular immune responses, we used a standard molecular adjuvant approach. It consisted of plasmids encoding murine IL-12 and IL-18 for a DNA-based vaccine and conventional Th1 type adjuvant, Quil A, for a protein-based vaccine. Both DNA- and protein-based vaccines induced Ag-specific CD4(+) T cell proliferation with Th1 and Th2 cytokine profiles, respectively. Protein-based, but not DNA-based, BORIS vaccine induced a significant level of Ab production in immunized animals. Importantly, potent anticancer CD8(+)-cytotoxic lymphocytes were generated after immunization with the DNA-based, but not protein-based, BORIS vaccine. These cytolytic responses were observed across a wide range of different mouse cancers including mammary adenocarcinoma, glioma, leukemia, and mastocytoma.
Development of a 50-A heaterless hollow cathode for electric thrusters (2022)

Hollow cathodes in electric thrusters normally use an external heater to raise the thermionic electron emitter to emission temperatures. These heaters are a potential single-point failure in the thruster and add a separate power supply to the power processing unit. Heaterless hollow cathodes are attractive for their compact size and potential higher reliability but have only been reliably demonstrated to date in small hollow cathodes capable of discharge currents below around 5 A. A new heaterless LaB<sub>6</sub> hollow cathode has been developed that is capable of discharge currents from 5 to 50 A. The cathode configuration extends the gas feed tube at cathode potential part way into the emitting insert region of the cathode. A high-voltage Paschen discharge is struck from the tube to the keeper that heats the tube tip, which then efficiently heats the insert by radiation. This configuration eliminates the arcing observed in prior large heaterless designs that coupled the high-voltage Paschen discharge to the orifice plate or the insert itself. Discharge current-voltage characteristics show that the presence of the tube does not significantly perturb the insert-region plasma. Startup uses a simple 3 min ignition procedure, and voltage traces of the keeper discharge reveal that much of the present tube-radiator's 100-to-150 W heating power comes from an intermediate thermionic discharge sustained by the tube during the transition between the Paschen discharge and LaB<sub>6</sub> insert thermionic regime. This novel heating mechanism enables an unprecedented class of higher-current heaterless hollow cathodes for the next generation of high-power electric propulsion systems.
Variable-focus liquid lens by changing aperture (2005)

We propose an adaptive liquid-filled lens, which consists of an elastic membrane, a solid plate, and an annular sealing ring; a liquid with a fixed volume stored in lens chamber. The key part is the annular sealing ring which looks like an iris diaphragm. The surfaces of annular sealing ring are sealed with an elastic membrane. The radius of the annular sealing ring is changeable. By tuning the radius of the annular sealing ring, the stored liquid in the lens will be redistributed, thus changing the curvature of the elastic membrane. Therefore, the lens cell causes light to converge or diverge. A liquid lens with a positive variable focus was demonstrated, this kind of lens has the advantages of simple fabrication process, compact structure, easy operation, and low cost.

In vitro Removal of Stain with Dentifrices (1982)

An in vitro model has been developed for the purpose of evaluating the cleaning ability of dentifrices. A stained film is slowly deposited on enamel sections and subsequently removed using a mechanical brushing procedure. Results from this test procedure compare favorably with the results of controlled, clinical cleaning studies.
Self-Stabilization of the Optical Frequencies and the Pulse Repetition Rate in a Coupled Optoelectronic Oscillator (2008)

A coupled optoelectronic oscillator (COEO) based on a laser with a high finesse intracavity etalon is presented. Unlike a conventional COEO, the incorporation of the etalon produces a 10.24-GHz spaced optical frequency comb by selecting a single optical supermode. The same etalon serves as a reference for active stabilization of the optical frequencies and the pulse repetition rate via the Pound-Drever-Hall stabilization method. This results in 160 to 190 comb lines with sub-1-MHz drift and sub-10-kHz linewidth, as well as subpicosecond pulses and 350-Hz maximum deviation of the pulse repetition rate over 10 min. The completely self-contained source allows the COEO utility to extend to a host of new coherent communication and signal processing applications.
Development of a Flexible and Wireless ECG Monitoring Device (2020)

A flexible wireless electrocardiogram (ECG) device was fabricated for monitoring physiological signals in wearable biomedical applications. The ECG device consists of dry electrodes and a readout module. The dry electrode was fabricated by depositing multi-walled carbon nanotube (MWCNT)/polydimethylsiloxane (PDMS) composite on a thermoplastic polyurethane (TPU) substrate with screen printed silver (Ag) layer. The readout module with wireless data transmission capability was designed and fabricated on a flexible polyimide substrate. The ECG device was attached to a fabric, and its performance was investigated by measuring the ECG signals and comparing the signals with the results of conventional wet Ag/AgCl ECG electrode ECG signals. It was observed that the device demonstrated equal performance in terms of signal intensity and correlation when compared to the conventional wet ECG electrodes. The methodology and results of the device are analyzed and presented in this paper.
