On the effect of ionization dead spaces on avalanche multiplication and noise for uniform electric fields (1990)

The effect of the impact ionization dead space on avalanche multiplication and noise has been assessed for uniform p-i-n avalanche photodiodes. This has required the development of a new numerical technique. The well-established McIntyre theory of avalanche noise [IEEE Trans. Electron Devices ED-13, 164 (1966)], which neglects the ionization dead-space effect, has been shown to overestimate the excess noise factor. The implications of the dead-space effect, for ionization coefficient determination and the interpretation of measured excess noise factors, are discussed.
An Artificial ‘Haemophilic’ Plasma for One‐Stage Factor‐VIII Assay (1978)

An 'artificial' plasma for one-stage factor-VIII assays is made by incubating human plasma with EDTA, to destroy factor VIII, and afterwards removing the anticoagulant by dialysis. Bovine factor V is then added to a given level. In the assay, contact activation is controlled by adding contact product. It was confirmed that factor-VIII activity was destroyed and that the EDTA was freely dialysable. The fibrinogen in the treated plasma clotted normally with thrombin. Likely variation in the factor-V activity was found not to be critical. The concentration of fibrinogen and other factors was adequate. Variation between batches was small. The artificial plasma yielded assay results closely comparable to haemophilic plasma in samples with factor-VIII activities in the range 0.01--20.0 iu/ml; the mean results in the artificial system were estimated to be 0.997 x those in haemophilic plasma, with a 95% confidence interval of 0.901--1.103. Biological variability in individual assays was smaller in the artificial system than when haemophilic plasma was used. Instability at the bench was more often detected in the artificial system than in haemophilic plasma assays, but the effect was eliminated from the results by obtaining duplicated readings in a balanced order.
CT features of hyperostosing meningioma en plaque (1987)

Hyperostosis of the sphenoid ridge or convexity of the skull associated with meningioma en plaque (MEP) is often confused with other hyperostosing conditions, such as fibrous dysplasia or osteoma. The authors present nine cases, six of them proven, of hyperostosing MEP with specific attention to the CT features. All nine cases had one or more CT features that were characteristic or suggestive of MEP. These included periosteal pattern of hyperostosis, inward bulging of the vault lesion, surface irregularity of the hyperostotic bone, and intracranial changes. The role of CT in evaluating MEP is compared with other neuroradiologic techniques. The results indicate that high-resolution CT is the neuroimaging method of choice in evaluating MEP.
Pain management in rheumatoid arthritis patients (1988)

Abstract To examine the effectiveness of a cognitive‐behavioral pain management program for patients with rheumatoid arthritis, three patient groups were studied: a cognitive‐behavioral group (CB), an attention‐placebo group, and a control group. The CB group received a comprehensive, 12‐month pain management program that taught coping strategies such as problem‐solving techniques, relaxation training, strategies for attention diversion, and training in family dynamics and communication. Dependent measures included pain, coping strategies, psychological status, functional status, and disease status. Data analysis at 12 months revealed benefits for the CB group in the area of enhanced coping strategies. Specifically, the CB subjects showed significantly greater use of coping strategies and significantly more confidence in their ability to manage pain. The findings are discussed in terms of the importance of enhanced self‐efficacy and personal control for patients with rheumatoid arthritis.
Robotic Applications in Cardiac Surgery (2004)

Traditionally, cardiac surgery has been performed through a median sternotomy, which allows the surgeon generous access to the heart and surrounding great vessels. As a paradigm shift in the size and location of incisions occurs in cardiac surgery, new methods have been developed to allow the surgeon the same amount of dexterity and accessibility to the heart in confined spaces and in a less invasive manner. Initially, long instruments without pivot points were used, however, more recent robotic telemanipulation systems have been applied that allow for improved dexterity, enabling the surgeon to perform cardiac surgery from a distance not previously possible. In this rapidly evolving field, we review the recent history and clinical results of using robotics in cardiac surgery.
Improving Communication Progress and Overlap in MPI Rendezvous Protocol over RDMA-enabled Interconnects (2008)

Overlapping computation with communication is a key technique to conceal the effect of communication latency on the performance of parallel applications. MPI is a widely used message passing standard for high performance computing. One of the most important factors in achieving a good level of overlap is the MPI ability to make progress on outstanding communication operations. In this paper, we address some of the communication progress shortcomings in the current polling and RDMA Read based Rendezvous protocol used for transferring large messages in MPI. We then propose a novel speculative Rendezvous protocol that uses RDMA Read and RDMA Write to effectively improve communication progress and consequently the overlap ability. Performance results based on a modified MPICH2 over 10-Gigabit iWARP Ethernet reveal a significant (80-100%) improvement in receiver side overlap and progress ability.

Fluorocarbon Coatings Via Plasma Enhanced Chemical Vapor Deposition of 1H,1H,2H,2H-perfluorodecyl Acrylate-1, Spectroscopic Characterization by FT-IR and XPS (2010)

Plasma polymerized fluorocarbon coatings were deposited on Thermanox coverslips and silicon wafers via plasma enhanced chemical vapor deposition (PECVD) of 1H,1H,2H,2H-perfluorodecyl acrylate (PFDA) monomer precursor in a low pressure inductively excited RF plasma, using argon as a carrier gas. PFDA coatings were characterized by Fourier transform infrared (FT-IR) and X-Ray photoelectron spectroscopy (XPS) techniques. The influence of plasma deposition parameters, such as precursor flow, deposition time, continuous wave (CW) and pulse modulated (PM) plasma mode, plasma power and plasma duty cycle (DC) on chemical composition of PFDA coatings was investigated. PFDA coatings with varying chemical compositions have been prepared at different plasma operating conditions. PM plasma mode, lower power, and lower DC plasma conditions yielded PFDA coatings with better chemical retention of precursor molecule, which was manifested by higher F/C ratio and CF2 group concentration, and lower CF/OCO concentration in PFDA coating under these conditions.
A Comparison of Different Defect Measures to Identify Defect-Prone Components (2013)

(Background) Defect distribution in software systems has been shown to follow the Pareto rule of 20-80. This motivates the prioritization of components with the majority of defects for testing activities. (Research goal) Are there significant variations between defective components and architectural hotspots identified by other defect measures? (Approach) We have performed a study using post-release data of an industrial Smart Grid application with a well-maintained defect tracking system. Using the Pareto principle, we identify and compare defect-prone and hotspots components based on four defect metrics. Furthermore, we validated the quantitative results against qualitative data from the developers. (Results) Our results show that at the top 25% of the measures 1) significant variations exist between the defective components identified by the different defect metrics and that some of the components persist as defective across releases 2) the top defective components based on number of defects could only identify about 40% of critical components in this system 3) other defect metrics identify about 30% additional critical components 4) additional quality challenges of a component could be identified by considering the pair wise intersection of the defect metrics. (Discussion and Conclusion) Since a set of critical components in the system is missed by using largest-first or smallest-first prioritization approaches, this study, therefore, makes a case for an all-inclusive metrics during defect model construction such as number of defects, defect density, defect severity and defect correction effort to make us better understand what comprises defect-prone components and architectural hotspots, especially in critical applications.
Relative Sensitivity of Hepatitis B Virus and Other Hepatotropic Viruses to the Antiviral Effects of Cytokines (2000)

We have previously shown that hepatitis B virus (HBV) replication is inhibited noncytopathically in the livers of transgenic mice following injection of HBV-specific cytotoxic T lymphocytes (CTLs) or infection with unrelated hepatotropic viruses, including lymphocytic choriomeningitis virus (LCMV) and adenovirus. These effects are mediated by gamma interferon (IFNgamma), tumor necrosis factor alpha (TNFalpha), and IFNalpha/beta. In the present study, we crossed HBV transgenic mice with mice genetically deficient for IFNgamma (IFNgammaKO), the TNFalpha receptor (TNFalphaRKO), or the IFNalpha/beta receptor (IFNalpha/betaRKO) in order to determine the relative contribution of each cytokine to the antiviral effects observed in each of these systems. Interestingly, we showed that HBV replicates in unmanipulated IFNgammaKO and IFNalpha/betaRKO mice at levels higher than those observed in control mice, implying that baseline levels of these cytokines control HBV replication in the absence of inflammation. We also showed that IFNgamma mediates most of the antiviral effect of the CTLs while IFNalpha/beta is primarily responsible for the early inhibitory effect of LCMV and adenovirus on HBV replication. In addition, we showed that the hepatic induction of IFNalpha/beta observed after injection of poly(I. C) is sufficient to inhibit HBV replication and that a similar antiviral effect is achieved by systemic administration of very high doses of IFNalpha. We also compared the relative sensitivity of LCMV and adenovirus to control by IFNgamma, TNFalpha, or IFNalpha/beta in these animals. Importantly, IFNalpha/betaRKO mice, and to a lesser extent IFNgammaKO mice, showed higher hepatic levels of LCMV RNA and adenovirus DNA and RNA than control mice, underscoring the importance of both interferons in controlling these other viral infections as well.

Randomly Amplified Polymorphic DNAs in the Cultivated Strawberry, Fragaria ×ananassa (1994)

Eight strawberry cultivars or advanced selections from the Univ. of California, Davis, breeding program were screened for polymorphisms using the polymerase chain reaction (PCR) and 43 random 10-base DNA primers. Over 60% of the primers screened resulted in replicable polymorphic banding patterns (amplification profiles), and a subset of ten primers that exhibited high levels of amplification profile polymorphism was used to identify each of the eight genotypes uniquely. There was also a significant product-moment correlation ( r = 0.64, P < 0.01) between number of shared amplification profile phenotypes and pairwise coefficient of coancestry. This technology shows high promise as a means of verifying the identity of cultivars and developing a genetic map of the octoploid cultivated strawberry.

Antimicrobial Photodynamic Efficiency of Novel Cationic Porphyrins towards Periodontal Gram‐positive and Gram‐negative Pathogenic Bacteria (2013)

Abstract The Gram‐negative Aggregatibacter actinomycetemcomitans and Fusobacterium nucleatum are major causative agents of aggressive periodontal disease. Due to increase in the number of antibiotic‐resistant bacteria, antimicrobial Photodynamic therapy ( aPDT ) seems to be a plausible alternative. In this work, photosensitization was performed on Gram‐positive and Gram‐negative bacteria in pure culture using new‐age cationic porphyrins, namely mesoimidazolium‐substituted porphyrin derivative ( ImP ) and pyridinium‐substituted porphyrin derivative ( PyP ). The photophysical properties of both the sensitizers including absorption, fluorescence emission, quantum yields of the triplet excited states and singlet oxygen generation efficiencies were evaluated in the context of aPDT application. The studied porphyrins exhibited high ability to accumulate into bacterial cells with complete penetration into early stage biofilms. As compared with ImP, PyP was found to be more effective for photoinactivation of bacterial strains associated with periodontitis, without any signs of dark toxicity, owing to its high photocytotoxicity.

Reversible electron beam heating for suppression of microbunching instabilities at free-electron lasers (2012)

The presence of microbunching instabilities due to the compression of high-brightness electron beams at existing and future x-ray free-electron lasers (FELs) results in restrictions on the attainable lasing performance and renders beam imaging with optical transition radiation impossible. The instability can be suppressed by introducing additional energy spread, i.e., heating the electron beam, as demonstrated by the successful operation of the laser heater system at the Linac Coherent Light Source. The increased energy spread is typically tolerable for self-amplified spontaneous emission FELs but limits the effectiveness of advanced FEL schemes such as seeding. In this paper, we present a reversible electron beam heating system based on two transverse deflecting radio-frequency structures (TDSs) upstream and downstream of a magnetic bunch compressor chicane. The additional energy spread is introduced in the first TDS, which suppresses the microbunching instability, and then is eliminated in the second TDS. We show the feasibility of the microbunching gain suppression based on calculations and simulations including the effects of coherent synchrotron radiation. Acceptable electron beam and radio-frequency jitter are identified, and inherent options for diagnostics and on-line monitoring of the electron beam's longitudinal phase space are discussed.
[Drug evaluation of huperzine A in the treatment of senile memory disorders]. (1991)

Huperzine A is an alkaloid which was first isolated from Huperzia serrata (Thumb) Trev by Zhejiang Academy of Medical Sciences and Shanghai Institute of Materia Medica, Chinese Academy of Sciences. It exhibits a significant anticholinesterase activity and has been used on myasthenia gravis patients. The therapeutic effects were studied by random, match and double-blind method on 56 patients of multi-infarct dementia or senile dementia and 104 patients of senile and presenile simple memory disorders. The curative effects were evaluated by Wechsler memory scale. The im dose for multi-infarct dementia was 0.05 mg bid for 4 wk, whereas that for senile and presenile simple memory disorders was 0.03 mg bid for 2 wk. Saline was used on control group. The result showed that the curative effect of huperzine A was significant. Only a few patients felt slight dizziness and this did not affect the therapeutic effects.
Clinical significance of urinary N1,N12-diacetylspermine levels in patients with hepatocellular carcinoma (2004)

DiAcSpm levels were found to reflect the severity, activity or viability of HCC. Urinary DiAcSpm can therefore be considered one of the useful indexes for patients with HCC.
An asymptotic analysis of hierarchical control of manufacturing systems (2003)

An asymptotic analysis of a hierarchical manufacturing system with machines subject to breakdown and repair is presented. The machine fluctuations are much faster than the accumulation and discounting of costs, and this gives rise to a limiting problem in which the stochastic machine availability is replaced by the equilibrium mean availability. The value function for the original problem converges to the value function of the limiting problem. The limiting problem is computationally tractable and sometimes has a closed-form solution.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Towards Distributed Coevolutionary GANs (2018)

Generative Adversarial Networks (GANs) have become one of the dominant methods for deep generative modeling. Despite their demonstrated success on multiple vision tasks, GANs are difficult to train and much research has been dedicated towards understanding and improving their gradient-based learning dynamics. Here, we investigate the use of coevolution, a class of black-box (gradient-free) co-optimization techniques and a powerful tool in evolutionary computing, as a supplement to gradient-based GAN training techniques. Experiments on a simple model that exhibits several of the GAN gradient-based dynamics (e.g., mode collapse, oscillatory behavior, and vanishing gradients) show that coevolution is a promising framework for escaping degenerate GAN training behaviors.
Alterations of amino acid repeats in the Escherichia coli hemolysin affect cytolytic activity and secretion. (1988)

The primary structure of the Escherichia coli hemolysin polypeptide (HlyA) is used to predict intramolecular structures involved in the secretion and cytolytic activity of the molecule. The C-terminal region of HlyA contains a repeated, 8-amino acid chain represented by the consensus sequence Leu-Xaa-Gly-Gly-Xaa-Gly-Asn-Asp. Three in vitro derived mutations of hlyA are described that encode molecules missing various portions of the C-terminal region, including the repeat region. The wild-type and mutated HlyA molecules were analyzed for the ability to be secreted and to lyse erythrocytes. Hemolytic activity absolutely requires the presence of the repeats. The ability of the mutated HlyA molecules to initiate membrane translocation and be secreted required the presence of the C terminus and, to a degree, the repeated amino acid octets.
Analysis of the mechanism of assembly of cleaved barnase from two peptide fragments and its relevance to the folding pathway of uncleaved barnase (1995)

A peptide corresponding to residues 1-22 of barnase that contains its major alpha-helix (residues 6-18) binds rapidly to the complementary peptide (residues 23-110) to form a catalytically active complex with near-native structure. Peptide 1-22 is approximately 3% helical in aqueous solution at 25 degrees C. A set of mutations in the helical regions of (1-22) cause the helix to be destabilized. We have investigated the mechanism of assembly of the peptides by analyzing the kinetics and equilibria of association of those mutants of (1-22) with native (23-110). The association reaction follows second-order kinetics. Virtually all the change in stability of the complex on mutation is reflected in changes in the association rate constant with the dissociation rate constant being very little affected. Both Brønsted and theta-value analyses show that the helix is essentially fully formed in the transition state for the association at all the positions probed (residues 13-18). Peptide (23-110) contains all the residues necessary for catalysis. The complexes between all mutants peptides (1-22) with (23-110) are all only 10% active, however. The noncovalent complex is destabilized less by mutations in the helix than is the intact protein. Double-mutant cycle and other analyses show, however, that the intrahelical interactions are as strong in the noncovalent complex as in the intact protein and so the interactions between the helix and the rest of the protein must be weakened on cleavage of the 22-23 bond. This could well lead to effects on catalysis.(ABSTRACT TRUNCATED AT 250 WORDS)
