The oxides with composition ${\mathrm{Y}}_{1\mathrm{\ensuremath{-}}\mathit{x}}$${\mathrm{Pr}}_{\mathit{x}}$${\mathrm{Ba}}_{2}$(${\mathrm{Cu}}_{3}$${\mathrm{O}}_{7\mathrm{\ensuremath{-}}\mathrm{\ensuremath{\delta}}}$)(0\ensuremath{\le}x\ensuremath{\le}1) 7-\ensuremath{\delta} (0\ensuremath{\le}x\ensuremath{\le}1) are characterized by x-ray diffraction, resistivity (\ensuremath{\rho}) and thermoelectric power (S) measurements. X-ray diffraction shows an orthorhombically distorted perovskite structure for all compositions, the pseudotetragonality increasing with x. The substitution of the tetravalent Pr for the trivalent Y atom increases the band filling in these materials. As a consequence, the superconducting transition temperature is progressively decreased with increasing x, and S significantly increases. Thermopower and resistivity measurements indicate that these oxides have relatively narrow bands and that the electronic correlations dominate their properties.
Unsupervised multistage image classification using hierarchical clustering with a bayesian similarity measure (2005)

A new multistage method using hierarchical clustering for unsupervised image classification is presented. In the first phase, the multistage method performs segmentation using a hierarchical clustering procedure which confines merging to spatially adjacent clusters and generates an image partition such that no union of any neighboring segments has homogeneous intensity values. In the second phase, the segments resulting from the first stage are classified into a small number of distinct states by a sequential merging operation. The region-merging procedure in the first phase makes use of spatial contextual information by characterizing the geophysical connectedness of a digital image structure with a Markov random field, while the second phase employs a context-free similarity measure in the clustering process. The segmentation procedure of region merging is implemented as a hierarchical clustering algorithm whereby a multiwindow approach using a pyramid-like structure is employed to increase computational efficiency while maintaining spatial connectivity in merging. From experiments with both simulated and remotely sensed data, the proposed method was determined to be quite effective for unsupervised analysis. In particular, the region-merging approach based on spatial contextual information was shown to provide more accurate classification of images with smooth spatial patterns.
Neutrophils in the initiation and resolution of acute pulmonary inflammation: understanding biological function and therapeutic potential (2018)

Acute respiratory distress syndrome (ARDS) is the often fatal sequelae of a broad range of precipitating conditions. Despite decades of intensive research and clinical trials there remain no therapies in routine clinical practice that target the dysregulated and overwhelming inflammatory response that characterises ARDS. Neutrophils play a central role in the initiation, propagation and resolution of this complex inflammatory environment by migrating into the lung and executing a variety of pro-inflammatory functions. These include degranulation with liberation of bactericidal proteins, release of cytokines and reactive oxygen species as well as production of neutrophil extracellular traps. Although these functions are advantageous in clearing bacterial infection, the consequence of associated tissue damage, the contribution to worsening acute inflammation and prolonged neutrophil lifespan at sites of inflammation are deleterious. In this review, the importance of the neutrophil will be considered, together with discussion of recent advances in understanding neutrophil function and the factors that influence them throughout the phases of inflammation in ARDS. From a better understanding of neutrophils in this context, potential therapeutic targets are identified and discussed. © 2018 The Authors.

Role of<i>Pseudomonas aeruginosa dinB</i>-Encoded DNA Polymerase IV in Mutagenesis (2006)

Pseudomonas aeruginosa is a human opportunistic pathogen that chronically infects the lungs of cystic fibrosis patients and is the leading cause of morbidity and mortality of people afflicted with this disease. A striking correlation between mutagenesis and the persistence of P. aeruginosa has been reported. In other well-studied organisms, error-prone replication by Y family DNA polymerases contributes significantly to mutagenesis. Based on an analysis of the PAO1 genome sequence, P. aeruginosa contains a single Y family DNA polymerase encoded by the dinB gene. As part of an effort to understand the mechanisms of mutagenesis in P. aeruginosa, we have cloned the dinB gene of P. aeruginosa and utilized a combination of genetic and biochemical approaches to characterize the activity and regulation of the P. aeruginosa DinB protein (DinB(Pa)). Our results indicate that DinB(Pa) is a distributive DNA polymerase that lacks intrinsic proofreading activity in vitro. Modest overexpression of DinB(Pa) from a plasmid conferred a mutator phenotype in both Escherichia coli and P. aeruginosa. An examination of this mutator phenotype indicated that DinB(Pa) has a propensity to promote C-->A transversions and -1 frameshift mutations within poly(dGMP) and poly(dAMP) runs. The characterization of lexA+ and DeltalexA::aacC1 P. aeruginosa strains, together with in vitro DNA binding assays utilizing cell extracts or purified P. aeruginosa LexA protein (LexA(Pa)), indicated that the transcription of the dinB gene is regulated as part of an SOS-like response. The deletion of the dinB(Pa) gene sensitized P. aeruginosa to nitrofurazone and 4-nitroquinoline-1-oxide, consistent with a role for DinB(Pa) in translesion DNA synthesis over N2-dG adducts. Finally, P. aeruginosa exhibited a UV-inducible mutator phenotype that was independent of dinB(Pa) function and instead required polA and polC, which encode DNA polymerase I and the second DNA polymerase III enzyme, respectively. Possible roles of the P. aeruginosa dinB, polA, and polC gene products in mutagenesis are discussed.
High transconductance heterostructure field-effect transistors based on AlGaN/GaN (1996)

We report on the fabrication and characterization of Al0.15Ga0.85N/GaN heterostructure field-effect transistors (HFETs) with transconductance as high as 120 mS/mm and saturated current density of 0.35 A/mm for a device with a gate length and width of 1 and 100 μm. This represents one of the best results for such device. A comparison of the maximum transconductance of devices on wafers with different channel conductance is presented to analyze the factors limiting the performance. Our data indicates the series resistance between the source and drain to be the limiting factor for the maximum dc transconductance.
The Effects of Time Delay and Echoes on Telephone Conversations (1963)

A brief history of the problem of echoes and delay in telephone connections is first given. Actual delays involved in typical circuits are shown. This is followed by a discussion of the effects of delay only on typical conversations. The sources of echo in typical telephone connections are then discussed, together with measures which have been taken to reduce echo by improving return loss. Methods of controlling the effects of delayed echo are then summarized; the summary includes a brief introduction to echo suppressors and some of the new problems they introduce
Cataloging and search engine for video library (2000)

The paper describes a prototype of cataloging and search engine for video library, the Video Library Search Engine (VLSE). We propose the system based on our codification of video data. There are two stages to provide a fast and efficient way to search, view and retrieve video information in the system. The first stage is global query videos according to video title, cast and the type of video such as Classical, Action, Western and so on. The second one is that for each video we can use a video metadata cataloging system to view it and provide various query methods such as query-by-feature, queryby -definition, query-by-keyword and structural-browsing. .
Engineering Significance of Ferrite Grain Size on the Radiation Sensitivity of Pressure Vessel Steels (1967)

A mathematical model was developed to describe the effect of ferrite grain size on the nil ductility transition temperature increase observed in irradiated pressure vessel steels. Experimental data illustrating the grain size effect are presented. The engineering significance of both the theoretical model and the experimental data are discussed, and it is shown that the neutron embrittlement problem may be greatly minimized by use of fine-grain steels. For Types A302B and A212B steels, shifts of less than 65 F in the 30 ft-1b Charpy transition temperature at an exposure of 3 × 1019 nvt (&gt;1 Mev) can be obtained with a ferrite grain size smaller than ASTM 9.
Fusion of a Novel Gene, BTL, to ETV6 in Acute Myeloid Leukemias With a t(4;12)(q11-q12;p13) (1999)

The ETV6 gene (also known as TEL) is the main target of chromosomal translocations affecting chromosome band 12p13. The rearrangements fuse ETV6 to a wide variety of partner genes in both myeloid and lymphoid malignancies. We report here 4 new cases of acute myeloid leukemia (AML) with very immature myeloblasts (French-American-British [FAB]-M0) and with a t(4;12)(q11-q12;p13). In all cases, ETV6 was found recombined to a new gene, homologous to the mouse Brx gene. The gene was named BTL (Brx-likeTranslocated in Leukemia). Reverse transcriptase-polymerase chain reaction (RT-PCR) experiments indicate that the expression of the BTL-ETV6 transcript, but not of the reciprocal ETV6-BTL transcript, is a common finding in these leukemias. In contrast to the majority of other ETV6 fusions, both the complete helix-loop-helix (HLH) and ETS DNA binding domains of ETV6 are present in the predicted BTL-ETV6 fusion protein, and the chimeric gene is transcribed from theBTL promoter.
Efficacy of prednisone 1–4 mg/day in patients with rheumatoid arthritis: a randomised, double-blind, placebo controlled withdrawal clinical trial (2008)

Efficacy of 1-4 mg prednisone was documented. Evidence of statistically significant differences with only 31 patients may suggest a robust treatment effect.
Designing Decoys for Chemokine-Chemokine Receptor Interaction (2002)

Aberrant expression of chemokines and their receptors play causative roles in the pathophysiology of numerous autoimmune and inflammatory disease processes. Moreover, an integral step in HIV infection involves binding to chemokine receptors, and hence chemokines are intimately linked to HIV-related diseases. Therefore, chemokines and their receptors are excellent targets for developing drugs that are more specific and may be of benefit in the management of disease. Knowledge of the chemokine and chemokine receptor structures, and an understanding of the structural basis of their function are essential for structure-aided design of receptor decoys. Chemokine ligands bind their receptors with nanomolar (nM) affinity, and successful design of a small molecule antagonist should bind the receptor with similar high affinity and specificity. Chemokines bind receptors that belong to the 7-transmembrane class on leukocytes, and highly negatively charged proteoglycans that are present on the cell surface. Structure-function studies have identified regions in both the ligand and the receptor that mediate binding and activation. Structures of numerous chemokines have been solved though very little is known regarding receptor structures. This review will summarize the current knowledge on the structures, structure-function, and the efficacy of chemokine derivatives and functional domain peptides as antagonists, and discuss strategies for exploiting this information for designing decoys for inflammatory, autoimmune, and HIV-related diseases.

Designing a Kubernetes Operator for Machine Learning Applications (2021)

Machine Learning workloads such as deep learning and hyperparameter tuning are compute-intensive by nature. Parallel execution is key to reducing the learning time. The Ray Framework is a distributed middleware that provides primitives to seamlessly parallelize machine learning code execution across a cluster of compute node. Launching a Ray managed machine learning application requires a Ray cluster that is diligently configured, well connected and easily scalable. Kubernetes, the container management middleware, satisfies all the requirements to create and scale ray clusters. However, setting up a cluster within Kubernetes, is a tedious and error prone task when done manually. In this paper we present KubeRay, an Operator and suite of tools designed, and built to create Ray cluster in Kubernetes with minimum effort. We present our architectural choices, our open-source implementation, and we analyze the performance of our solution.

Minimal cluster expansion models of B-site cation ordering in ${A(B}_{1/3}^{\ensuremath{'}}{,B}_{2/3}^{\ensuremath{''}}){\mathrm{O}}_{3}$ perovskites are evaluated. It is demonstrated that the linear triplet interaction is both necessary and sufficient to stabilize the $P\overline{3}m1 1:2$ structure ground state that is observed in such compounds as $\mathrm{Ba}({\mathrm{Zn}}_{1/3},{\mathrm{Nb}}_{2/3}){\mathrm{O}}_{3}$ and $\mathrm{Ba}({\mathrm{Zn}}_{1/3},{\mathrm{Ta}}_{2/3}){\mathrm{O}}_{3}.$ The linear triplet model exhibits a $P\overline{3}m\stackrel{\ensuremath{\rightarrow}}{1}\mathrm{Pm}\overline{3}m$ transition at ${\mathrm{kT}}_{C}/[\ensuremath{-}{J}_{(\ifmmode\bullet\else\textbullet\fi{}\ensuremath{-}\ifmmode\bullet\else\textbullet\fi{}\ensuremath{-}\ifmmode\bullet\else\textbullet\fi{})}]=4.5184.$ The addition of a nearest-neighbor pair interaction permits the transition sequence $P\overline{3}m\stackrel{\ensuremath{\rightarrow}}{1}\mathrm{Fm}\overline{3}m1:1 \mathrm{structure}\ensuremath{\rightarrow}\mathrm{Pm}\overline{3}m,$ which is observed in $\mathrm{Ca}({\mathrm{Ca}}_{1/3},{\mathrm{Nb}}_{2/3}){\mathrm{O}}_{3},$ but not in a region of parameter space in which the lowest-energy ground state of the ${\mathrm{AB}}_{x}^{\ensuremath{'}}{\mathrm{O}}_{3}\ensuremath{-}{\mathrm{AB}}_{1\ensuremath{-}x}^{\ensuremath{''}}{\mathrm{O}}_{3}$ pseudobinary occurs at the ${A(B}_{1/3}^{\ensuremath{'}}{,B}_{2/3}^{\ensuremath{''}}){\mathrm{O}}_{3}$ composition. This latter condition can be satisfied by including a second many-body interaction, specifically, a cube minus the triangle of three second-neighbor pairs. Monte Carlo simulations with such a model generate microstructures of the type that are observed in $\mathrm{Pb}({\mathrm{Zn}}_{1/3},{\mathrm{Nb}}_{2/3}){\mathrm{O}}_{3}$ and $\mathrm{Pb}({\mathrm{Mg}}_{1/3},{\mathrm{Nb}}_{2/3}){\mathrm{O}}_{3}.$
Autocrine Stimulation of Intracellular PDGF Receptors in v- <i>sis</i> -Transformed Cells (1988)

Autocrine activation of platelet-derived growth factor (PDGF) receptors is the mechanism of transformation by the v-sis oncogene. Since the addition of PDGF does not transform normal cells, autocrine mechanisms may involve unique pathways of receptor activation. In this study autocrine stimulation of the PDGF receptor was observed in v-sis-transformed normal rat kidney (NRK) cells. In contrast to receptor activation in normal cells, autocrine activation of PDGF receptors in v-sis-transformed cells occurred in intracellular compartments, disrupting receptor processing and diverting receptors and their precursors to a chloroquine-sensitive degradation pathway. These findings show that intracellular activation of receptors by autocrine mechanisms may play a role in cell transformation.
AN OBSTETRIC RING FOR ARTIFICIAL PUNCTURE OF THE MEMBRANES (1935)

Artificial puncture of the membranes is the simplest of obstetric operations. When one observes the awkwardness with which the operation is performed by inexperienced physicians and the amount of unnecessary trauma sometimes inflicted in attempting to rupture the membranes, the need for a simple, effective and harmless instrument becomes obvious. The ring that I have devised is made of malleable metal so that it can be fitted to the gloved forefinger just behind the first joint. A rigid, notched projection extends along the dorsum of the first phalanx with the point directed to the inner aspect of the fingernail. When the finger is introduced into the vagina, the projection lies flat against the gloved finger, so that no trauma is inflicted on the mucous membrane of the vagina or on the cervix. Examination of the cervix and of the presenting parts may be made
Transient Increases in Numbers of Infectious Cells in an HIV-infected Chimpanzee Following Immune Stimulation (1992)

Efficient replication and production of human immunodeficiency virus (HIV) has been shown to be influenced greatly not only by the activation state of the infected cell but also by a variety of cytokines. Thus, it seems reasonable to assume, as has been hypothesized, that any stimulus to the immune system, whether by intercurrent infection, exposure to new or recall antigens, or injury with inflammation, could enhance HIV expression in infected individuals. To test this hypothesis, we subjected an HIV-1-infected chimpanzee to repeated specific and nonspecific immune stimulation by inoculation of various vaccine preparations, adjuvant alone, or HIV-specific immune globulin. Transient increases both in numbers of infectious peripheral blood cells and in some HIV-specific immune responses occurred within 1 to 2 weeks after most inoculations, including administration of the immune globulin. These results have important implications for the use of immunotherapy as a treatment for HIV-infected persons and for immunization of HIV-infected infants and children against other pathogens. They suggest that both immunotherapy and vaccination of HIV-infected individuals should be accompanied by administration of an antiviral drug(s).
Mitochondrial respiratory activity is altered in osteoarthritic human articular chondrocytes (2003)

These findings suggest the involvement of mitochondrial function in the pathophysiology of OA. Cartilage degradation by OA and cartilage aging may be two different processes.
Isolated feedback for off-line switching power supplies with primary-side control (2003)

Safety regulations require galvanic isolation between the AC line voltage and the outputs of switch-mode power supplies, making implementation of the feedback-control loop difficult. Four existing schemes for providing feedback information across the isolation barrier are examined. The schemes are identified as opto-couplers, amplitude modulation of the error signal, amplitude modulation of the output voltage, and communication of the drive pulse across the barrier. Each is examined with regard to steady-state and frequency-domain considerations.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
