Direction finding of coherent signals via spatial smoothing for uniform circular arrays (1994)

We present a preprocessing technique that in conjunction with spatial smoothing circumvents the difficulty of direction-of-arrival estimation of coherent signals in the case of uniform circular arrays. Special consideration is given to problems arising in practice, such as mutual coupling and array geometry imperfections. Simulation results illustrating the performance of this scheme in conjunction with the MUSIC method are included.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Selective node engineering for chip-level soft error rate improvement [in CMOS] (2003)

This paper presents a technique to selectively engineer sequential or domino nodes in high performance circuits to improve soft error rate (SER) induced by cosmic rays or alpha particles. In 0.18 /spl mu/m process, the SER improvement is as much as 3/spl times/ at the cell-level, 1.8/spl times/ at the block-level and 1.3/spl times/ at the chip-level without any penalty in performance or area, and <3% power penalty. The node selection, hardening and SER quantification steps are fully automated.
The Effect of Training on Performance Efficiency During a Competitive Isometric Exercise (1973)

Male college students (N = 15) participated in a competitive isometric exercise involving elbow flexion. The men were grouped into five teams each consisting of three men. A prize of $25 was offered to the team which maintained the greatest force for the longest time. Prior to the competitive session each S practiced individually on the apparatus for eight sessions. The men were randomly assigned to the teams on the day of the competition. During each session, continuous EMG recordings were made on the biceps muscle of the right arm. Training significantly improved both strength and endurance while reducing the average EMG amplitude. When team competition was introduced, there was a decrease in endurance and an increase in EMG amplitude, it was concluded that training improved muscular strength and endurance by increasing the efficiency of muscle utilization. Competition, even with a partially trained skill, was considered a stressful situation that produced an overexpenditure of muscle activity and a resulting decrease in performance.
Magnetic anisotropy of ferromagnetic La0.7Sr0.3MnO3 epitaxial thin films: Dependence on temperature and film thickness (2002)

The magnetic anisotropy of (001) oriented La0.7Sr0.3MnO3 films of thickness t=7–156 nm, deposited on LaAlO3 substrates, was measured by torque magnetometry in the temperature range T=10–300 K. For t⩾50 nm and H rotating out of plane the anisotropy Ku agrees well with shape anisotropy. For thinner films, Ku is reduced and its sign is reversed for t=7 nm and T&lt;70 K; this can be explained by a perpendicular anisotropy Kuε due to lattice strain. The crystal anisotropy constant K1 was determined from the biaxial in-plane anisotropy. At T=100 K K1 differed by no more than 50% from the mean value −8 kJ/m3 in the thickness region investigated. K1 was much less dependent on the thickness t and strain relaxation in the films than Kuε.
Statistical Discrimination of the Synonymy/Antonymy Relationship Between Words (1967)

A basic hypothesis is stated about the contextual and co-occurrence properties of synonymous words. On the basis of this hypothesis, several statistics are derived for use in discriminating between pairs of words which are synonymous and pairs of words which are nonsynonymous. The discriminating power of these statistics is tested on a corpus consisting of titles of physics theses. The tests indicate that two of the derived statistics have relatively high discriminating power. The results are interpreted and the possibility of obtaining better discriminating power is discussed.
Robust 1D Barcode Recognition on Mobile Devices (2010)

In the following we will describe a novel method for decoding linear barcodes from blurry camera images. Our goal was to develop a algorithm that can be used on mobile devices to recognize product numbers from EAN or UPC barcodes.
Improvement of polycrystalline silicon solar cells with grain-boundary hydrogenation techniques (1980)

Electron-beam-induced-current– and dark-current–voltage measurements have been made on p/n photovoltaic cells fabricated from polycrystalline silicon. These data have demonstrated that grain-boundary hydrogenation greatly reduces grain-boundary minority carrier recombination and improves diode current-voltage characteristics.
What makes things fun to learn? heuristics for designing instructional computer games (1980)

In this paper, I will describe my intuitions about what makes computer games fun. More detailed descriptions of the experiments and the theory on which this paper is based are given by Malone (1980a, 1980b). My primary goal here is to provide a set of heuristics or guidelines for designers of instructional computer games. I have articulated and organized common sense principles to spark the creativity of instructional designers (see Banet, 1979, for an unstructured list of similar principles). To demonstrate the usefulness of these principles, I have included several applications to actual or proposed instructional games. Throughout the paper I emphasize games with educational uses, but I focus on what makes the games fun, not on what makes them educational.
Ionic-Liquid-Promoted Decaborane Dehydrogenative Alkyne-Insertion Reactions: A New Route to <i>o</i>-Carboranes (2008)

Unlike in conventional organic solvents, where Lewis base catalysts are required, decaborane dehydrogenative alkyne-insertion reactions proceed rapidly in biphasic ionic-liquid/toluene mixtures with a wide variety of terminal and internal alkynes, thus providing efficient, one-step routes to functional o-carborane 1-R-1,2-C2B10H11 and 1-R-2-R'-1,2-C2B10H10 derivatives, including R = C6H5- (1), C6H13- (2), HC[triple bond]C-(CH2)5- (3), (1-C2B10H11)-(CH2)5- (4), CH3CH2C(O)OCH2- (5), (C2H5)2NCH2- (6), NC-(CH2)3- (7), 3-HC[triple bond]C-C6H4- (8), (1-C2B10H11)-1,3-C6H4- (9), HC[triple bond]C-CH2-O-CH2- (10); R,R' = C2H5- (11); R = HOCH2-, R' = CH3- (12); R = BrCH2-; R' = CH3- (13); R = H2C=C(CH3)-, R' = C2H5- (14). The best results were obtained from reactions with only catalytic amounts of bmimCl (1-butyl-3-methylimidazolium chloride), where in many cases reaction times of less than 20 min were required. The experimental data for these reactions, the results observed for the reactions of B10H13(-) salts with alkynes, and the computational studies reported in the third paper in this series all support a reaction sequence involving (1) the initial ionic liquid promoted formation of the B10H13(-) anion, (2) addition of B10H13(-) to the alkyne to form an arachno-R,R'-C2B10H13(-) anion, and (3) protonation of arachno-R,R'-C2B10H13(-) to form the final neutral 1-R-2-R'-1,2-C2B10H10 product with loss of hydrogen.
Infectivity and Pathogenicity in Chimpanzees of a Surface Gene Mutant of Hepatitis B Virus that Emerged in a Vaccinated Infant (1997)

Hepatitis B virus (HBV) variants with amino acid mutations in the a epitope of the major surface protein have been identified, and questions have been raised regarding their biologic properties. Dilutions of serum that contained the first such described HBV mutant, with an Arg-for-Gly substitution at codon 145 of the S gene, were inoculated into 6 seronegative chimpanzees. Five of the animals developed serologic and/or biochemical evidence of hepatitis B. A polymerase chain reaction-based assay that discriminated between the wild type and mutant viral genomes revealed that a pure population of the mutant genome was present in the 10(-6) and 10(-7) dilutions of the index serum, resulting in infection of the chimpanzees receiving these dilutions only with the mutant virus. A clone of the mutant virus replicated normally following transfection in vitro. Thus, this HBV surface gene mutant is viable, infectious, and pathogenic in chimpanzees.

VLSI Implementation of two-dimensional generalized mean filter (2005)

In a black-and-white digitized image, pixels corrupted by impulse noise appear as either black dots or white dots. In this paper, the VLSI implementation of two-dimensional generalized mean filtering for the removal of such impulse noises has been presented. The designed chip is capable of filtering each pixel inside the image within 14 clock cycles and is highly suitable for real-time application.
Acriflavine violet red bile agar for the isolation of Klebsiella. (1977)

A medium for the isolation and detection of Klebsiella is described. It contains 0.06% Acriflavine in Violet Red Bile agar (Difco). Klebsiella appeared as 5 to 7 mm mucoid (24 h at 37 degrees C) golden-yellow colonies. Pseudomonas aeruginosa and Enterobacter spp. appeared as small, brown to dark brown colonies. Escherichia coli as well as many other gram negative organisms and gram positive organisms did not grow on this medium.
Core/Shell Macrobeads for the Protection of Islets from Immune System Rejection (2005)

Core/shell macrobeads, composed of a hydrogel core and a biodegradable polymeric shell, were designed and evaluated for the protection of islets from both fibrous tissue development as well as the modulation of the immune system rejection response. The core/shell macrobeads (2,000μm diameter) were prepared with approximately 150μm thick polymeric shells. Islets isolated from pancreas of C57/BL6 mice were encapsulated in these core/shell macrobeads. The islets-loaded core/shell macrobeads were planted in the peritoneal cavity of diabetes mellitus-induced C57/BL6 mice and the blood glucose concentrations were measured.
Nanofibrous Smart Fabrics from Twisted Yarns of Electrospun Piezopolymer (2017)

Smart textiles are envisioned to make a paradigm shift in wearable technologies to directly impart functionality into the fibers rather than integrating sensors and electronics onto conformal substrates or skin in wearable devices. Among smart materials, piezoelectric fabrics have not been widely reported, yet. Piezoelectric smart fabrics can be used for mechanical energy harvesting, for thermal energy harvesting through the pyroelectric effect, for ferroelectric applications, as pressure and force sensors, for motion detection, and for ultrasonic sensing. We report on mechanical and material properties of the plied nanofibrous piezoelectric yarns as a function of postprocessing conditions including thermal annealing and drawing (stretching). In addition, we used a continuous electrospinning setup to directly produce P(VDF-TrFE) nanofibers and convert them into twisted plied yarns, and demonstrated application of these plied yarns in woven piezoelectric fabrics. The results of this work can be an early step toward realization of piezoelectric smart fabrics.
In(III)-Mediated Chemoselective Dehydrogenative Interaction of ClMe<sub>2</sub>SiH with Carboxylic Acids:  Direct Chemo- and Regioselective Friedel−Crafts Acylation of Aromatic Ethers (2007)

[reaction: see text] Chemoselective dehydrogenative interaction of ClMe(2)SiH with a carboxylic acid group in the presence of InX3 is reported. 13C NMR investigation revealed the formation of PhCOOSi(Cl)Me(2) as the major transient intermediate. Chemo- and regioselective Friedel-Crafts acylation of aromatic ethers directly from carboxylic acids was established.
A semantic feature language for concurrent engineering (2009)

In this paper, we present a semantic feature language for knowledge representation and reasoning across different domains in concurrent engineering (CE). The proposed language utilizes a feature model which is depicted in two levels. First a unified and formal framework is presented for semantic features in CE. The presented semantic features are general and a feature formal language is used to characterize the engineering data in multi-discipline domains at the most abstract level. At the details level, the general semantic features are realized in a hierarchical manner with the aids of object-oriented programming. A preliminary implementation of the proposed semantic feature model is also presented.
Pharmacokinetics and tolerability of <scp>SRT</scp>2104, a first‐in‐class small molecule activator of <scp>SIRT</scp>1, after single and repeated oral administration in man (2012)

In the absence of an optimized formulation of SRT2104, the food effect can be used to maximize exposure in future clinical studies. Combined with the good tolerability of all doses demonstrated in these studies, the favourable selectivity profile of SRT2104 allows for the use of this SIRT1 modulator for target validation in the clinic.
The Checkpoint Kinase Inhibitor AZD7762 Potentiates Chemotherapy-Induced Apoptosis of <i>p53</i> -Mutated Multiple Myeloma Cells (2012)

DNA cross-linking agents are frequently used in the treatment of multiple myeloma-generating lesions, which activate checkpoint kinase 1 (Chk1), a critical transducer of the DNA damage response. Chk1 activation promotes cell survival by regulating cell-cycle arrest and DNA repair following genotoxic stress. The ability of AZD7762, an ATP-competitive Chk1/2 inhibitor to increase the efficacy of the DNA-damaging agents bendamustine, melphalan, and doxorubicin was examined using four human myeloma cell lines, KMS-12-BM, KMS-12-PE, RPMI-8226, and U266B1. The in vitro activity of AZD7762 as monotherapy and combined with alkylating agents and the "novel" drug bortezomib was evaluated by studying its effects on cytotoxicity, signaling, and apoptotic pathways. The Chk1/2 inhibitor AZD7762 potentiated the antiproliferative effects of bendamustine, melphalan, and doxorubicin but not bortezomib in multiple myeloma cell lines that were p53-deficient. Increased γH2AX staining in cells treated with bendamustine or melphalan plus AZD7762 indicates a greater degree of DNA damage with combined therapy. Abrogation of the G(2)-M checkpoint by AZD7762 resulted in mitotic catastrophe with ensuing apoptosis evidenced by PARP and caspase-3 cleavage. In summary, the cytotoxic effects of bendamustine, melphalan and doxorubicin on p53-deficient multiple myeloma cell lines were enhanced by the coadministration of AZD7762. These data provide a rationale for testing these combinations in patients with relapsed and/or refractory multiple myeloma.

Studies on hepatic uptake of antigen. I. Comparison of inferior vena cava and portal vein routes of immunization. (1973)

An experimental animal model is described in which small injections of antigen (SRBC) into the portal venous system of the rat produces a reduced immune response in comparison with that obtained following similar injection into the inferior vena cava. The difference in humoral response, measured by circulating haemagglutinins and haemolysins was only detectable after repeated doses of antigen. The dose of SRBC necessary to demonstrate this difference is shown to be critical. Cell-mediated immunity—determined by measuring ear swelling 24 hours after intra-auricular injection of antigen—could be demonstrated in animals immunized via the inferior vena cava but not in those immunized via the portal vein. Labelling of the antigen with radioactive chromium ((51)Cr) showed that the increased immune response to inferior vena cava injected antigen was accompanied by a reduced hepatic uptake of antigen, but no significant alteration in splenic uptake.
Sensory Adaptation and Short Term Plasticity as Bayesian Correction for a Changing Brain (2010)

Neurons in the sensory system exhibit changes in excitability that unfold over many time scales. These fluctuations produce noise and could potentially lead to perceptual errors. However, to prevent such errors, postsynaptic neurons and synapses can adapt and counteract changes in the excitability of presynaptic neurons. Here we ask how neurons could optimally adapt to minimize the influence of changing presynaptic neural properties on their outputs. The resulting model, based on Bayesian inference, explains a range of physiological results from experiments which have measured the overall properties and detailed time-course of sensory tuning curve adaptation in the early visual cortex. We show how several experimentally measured short term plasticity phenomena can be understood as near-optimal solutions to this adaptation problem. This framework provides a link between high level computational problems, the properties of cortical neurons, and synaptic physiology.
IOP Tool: Assessing the Benefits and Hindrances of Information Integration Implementation Opportunities (2011)

This paper presents a tool assessing the benefits and hindrances of specific information integration opportunities (IOP) identified by firms for potential implementation. Firms face numerous choices about which of many potential information integration opportunities to pursue. However, they lack guidance in selecting opportunities and preparing for successful implementation. In addition, there are many nontechnical factors that need to be considered for successful implementation of information integration. The tool, developed by an industry research team consisting of 15 members from leading contractors, construction clients, and academia in the U.S., uses 37 benefit driver and 34 implementation hindrance questions that are scored to provide an assessment of a specific integration opportunity. The questions in the tool take market/legal, organizational and process, and people-related issues pertinent to the implementation of information integration into account. The tool has been applied to 16 test cases and is shown to adequately address key benefits and challenges, helping guide implementation choices.
Jericho: Achieving scalability through optimal data placement on multicore systems (2014)

Achieving high I/O throughput on modern servers presents significant challenges. With increasing core counts, server memory architectures become less uniform, both in terms of latency as well as bandwidth. In particular, the bandwidth of the interconnect among NUMA nodes is limited compared to local memory bandwidth. Moreover, interconnect congestion and contention introduce additional latency on remote accesses. These challenges severely limit the maximum achievable storage throughput and IOPS rate. Therefore, data and thread placement are critical for data-intensive applications running on NUMA architectures. In this paper we present Jericho, a new I/O stack for the Linux kernel that improves affinity between application threads, kernel threads, and buffers in the storage I/O path. Jericho consists of a NUMA-aware filesystem and a DRAM cache organized in slices mapped to NUMA nodes. The Jericho filesystem implements our task placement policy by dynamically migrating application threads that issue I/Os based on the location of the corresponding I/O buffers. The Jericho DRAM I/O cache, a replacement for the Linux page-cache, splits buffer memory in slices, and uses per-slice kernel I/O threads for I/O request processing. Our evaluation shows that running the FIO microbenchmark on a modern 64-core server with an unmodified Linux kernel results in only 5% of the memory accesses being served by local memory. With Jericho, more than 95% of accesses become local, with a corresponding 2x performance improvement.
