CNN-Based Bi-Directional Motion Compensation for High Efficiency Video Coding (2018)

The state-of-the-art High Efficiency Video Coding (HEVC) standard adopts the bi-prediction to improve the coding efficiency for B frame. However, the underlying assumption of this technique is that the motion field is characterized by the block-wise translational motion model, which may not be efficient in the challenging scenarios such as rotation and deformation. Inspired by the excellent signal level prediction capability of deep learning, we propose a bi-directional motion compensation algorithm with convolutional neural network, which is further incorporated into the video coding pipeline to improve the performance of video compression. Our network consists of six convolutional layers and a skip connection, which integrates the prediction error detection and non-linear signal prediction into an end-to-end framework. Experimental results show that by incorporating the proposed scheme into HEVC, up to 10.5% BD-rate savings and 3.1% BD-rate savings on average for random access (RA) configuration have been observed.
The Fourth Positive System of Carbon Monoxide Observed in Absorption at High Resolution in the Vacuum Ultraviolet Region (1969)

The fourth positive system (A `ll-X'~) of carbon monoxide has been observed in absorption at high resolution in the region 1550-1060 A The rotational and vibrational structure of twenty-three bands has been analyzed, viz , the v" = 0 progression for v' = 0-18, 20, 21, and 23 in addition to the (0,1)- band. A detailed assignment of the numerous perturbations in the A ~IJ state is given Most of these per- turbations can easily be attributed to the six known states in the region of the A `H state The observed = 23 level lies above the accepted dissociation limit of CO which indicates a maximum in the potential curve for the A 111 stat
Speech Enhancement Based on Filtering the Spectrotemporal Modulations (2006)

A monaural noise suppression algorithm is proposed based on filtering the spectrotemporal modulations of noisy speech. The modulations are estimated from a multiscale representation of the signal spectrogram generated by a model of sound processing in the auditory system. A significant advantage of this method is its ability to suppress noise that has distinctive modulation patterns, despite being spectrally overlapping with the speech. The performance of the algorithm is evaluated using subjective and objective tests and compared to the optimal smoothing and minimum statistics approach (Martin (2001)). The results demonstrate the efficacy of the spectrotemporal filtering approach in the conditions examined.
Air‐Stable Cesium Lead Iodide Perovskite for Ultra‐Low Operating Voltage Resistive Switching (2017)

Abstract CsPbX 3 (X = halide, Cl, Br, or I) all‐inorganic halide perovskites (IHPs) are regarded as promising functional materials because of their tunable optoelectronic characteristics and superior stability to organic–inorganic hybrid halide perovskites. Herein, nonvolatile resistive switching (RS) memory devices based on all‐inorganic CsPbI 3 perovskite are reported. An air‐stable CsPbI 3 perovskite film with a thickness of only 200 nm is successfully synthesized on a platinum‐coated silicon substrate using low temperature all‐solution process. The RS memory devices of Ag/polymethylmethacrylate (PMMA)/CsPbI 3 /Pt/Ti/SiO 2 /Si structure exhibit reproducible and reliable bipolar switching characteristics with an ultralow operating voltage (<+0.2 V), high on/off ratio (>10 6 ), reversible RS by pulse voltage operation (pulse duration < 1 ms), and multilevel data storage. The mechanical flexibility of the CsPbI 3 perovskite RS memory device on a flexible substrate is also successfully confirmed. With analyzing the influence of phase transition in CsPbI 3 on RS characteristics, a mechanism involving conducting filaments formed by metal cation migration is proposed to explain the RS behavior of the memory device. This study will contribute to the understanding of the intrinsic characteristics of IHPs for low‐voltage resistive switching and demonstrate the huge potential of them for use in low‐power consumption nonvolatile memory devices on next‐generation computing systems.
Structural Requirements for the Complement Regulatory Activities of C4BP (2001)

C4b-binding protein (C4BP) is a regulator of the classical complement pathway C3 convertase (C4bC2a complex). It is a disulfide-linked polymer of seven alpha-chains and a unique beta-chain; the alpha- and beta-chains are composed of eight and three complement control protein (CCP) domains, respectively. To elucidate the importance of the polymeric nature of C4BP and the structural requirements for the interaction between C4b and the alpha-chain, 19 recombinant C4BP variants were created. Six truncated monomeric variants, nine polymeric variants in which individual CCPs were deleted, and finally, four variants in which double alanine residues were introduced between CCPs were functionally characterized. The smallest truncated C4BP variant still active in regulating fluid phase C4b comprised CCP1-3. The monomeric variants were less efficient than polymeric C4BP in degrading C4b on cell surfaces. All three N-terminal CCP domains contributed to the binding of C4b and were important for full functional activity; CCP2 and CCP3 were the most important. The spatial arrangements of the first CCPs were found to be important, as introduction of alanine residues between CCPs 1 and 2, CCPs 2 and 3, and CCPs 3 and 4 resulted in functional impairment. The results presented here elucidate the structural requirements of individual CCPs of C4BP, as well as their spatial arrangements within and between subunits for expression of full functional activity.

Degarelix versus LHRH agonists: Differential skeletal and urinary tract outcomes from an analysis of six comparative randomized clinical trials. (2013)

68 Background: The use of ADT in men with prostate cancer is well established. GnRH antagonists have a mode of action distinct to that of LHRH agonists and comparative trials have shown differences in efficacy and safety between these agents. Adverse events (AE) from the musculoskeletal and renal and urinary systems have now been analysed. Methods: Results were pooled from 6 prospective, comparative randomised trials (n=2328). Most patients (pts) received 1 year of degarelix or LHRH agonist treatment (n=1686); the remaining men had 3–7 months’ treatment (n=642). AEs were analysed using Kaplan Meier plots and a log-rank test for homogeneity on relevant groups of MedDRA terms. Results: Treatment groups (degarelix, n=1491; LHRH agonist, n=837) were balanced for baseline characteristics such as age, testosterone, PSA and disease stage. In men with metastatic disease alkaline phosphatase (ALP) was reduced to a greater extent with degarelix (p=0.0373) throughout the year. Overall probability of fracture (<1% vs. 2%, p=0.0411) and incidence of joint related AEs (4% vs. 6%, p=0.0116) were significantly lower for degarelix-treated men. Incidence of muscle or bone pain was lower for degarelix (9% vs. 12%, p=0.0822). Incidence of urinary infections (UI) was reduced (5% vs. 8% with agonists) and time to first UI was significantly increased (p=0.0010) with degarelix. Overall probability of any renal or urinary tract AEs, including lower urinary tract symptoms (LUTS), was significantly lower in pts receiving degarelix (p<0.0001). Consistent with fewer skeletal and urinary tract AEs indicating better disease control, men with baseline PSA >50 ng/mL had significantly higher PSA PFS compared to agonist treated pts. OS during 1 year of treatment was significantly higher for degarelix pts (98.3% vs. 96.7%, p=0.0329). Conclusions: This analysis of 2,328 men shows degarelix-treated men had lower ALP, significantly fewer fractures, a lower incidence of urinary tract symptoms and higher overall survival than pts receiving an LHRH agonist over one year. Control of such disease symptoms is consistent with previous data on a significantly lower risk of PSA PFS during the first year of treatment.
Homocysteine and Ischemic Heart Disease (1998)

Our positive results help resolve the uncertainty that resulted from previous prospective studies. The epidemiological, genetic, and animal evidence together indicate that the association between serum homocysteine level and IHD is likely to be causal. A general increase in consumption of the vitamin folic acid (which reduces serum homocysteine levels) would, therefore, be expected to reduce mortality from IHD.
Predictive Control Strategy for DC/AC Converters Based on Direct Power Control (2007)

<para xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> This paper proposes predictive direct power control (P-DPC), a new control approach where the well-known direct power control is combined with predictive selection of a voltage-vectors' sequence, obtaining both high transient dynamics and a constant-switching frequency. The developed P-DPC version is based on an optimal application of three voltage vectors in a symmetrical way, which is the so-called symmetrical 3 <formula formulatype="inline"><tex>$+$</tex></formula> 3 vectors' sequence. The simulation and experimental results of the P-DPC are compared to standard voltage-oriented control (VOC) strategies in a grid-connected three-phase voltage-source inverter under 400-V 15-kVA operation conditions. The P-DPC improves the transient response and keeps the steady-state harmonic spectrum at the same level as the VOC strategies. Due to its high transient capability and its constant-switching behavior, the P-DPC could become an interesting alternative to standard VOC techniques for grid-connected converters. </para>
SERIES: Genomic instability in cancer Balancing repair and tolerance of DNA damage caused by alkylating agents (2012)

Alkylating agents constitute a major class of frontline chemotherapeutic drugs that inflict cytotoxic DNA damage as their main mode of action, in addition to collateral mutagenic damage. Numerous cellular pathways, including direct DNA damage reversal, base excision repair (BER) and mismatch repair (MMR), respond to alkylation damage to defend against alkylation-induced cell death or mutation. However, maintaining a proper balance of activity both within and between these pathways is crucial for a favourable response of an organism to alkylating agents. Furthermore, the response of an individual to alkylating agents can vary considerably from tissue to tissue and from person to person, pointing to genetic and epigenetic mechanisms that modulate alkylating agent toxicity.
Global transcriptome analysis and enhancer landscape of human primary T follicular helper and T effector lymphocytes (2014)

T follicular helper (Tfh) cells are a subset of CD4(+) T helper cells that migrate into germinal centers and promote B-cell maturation into memory B and plasma cells. Tfh cells are necessary for promotion of protective humoral immunity following pathogen challenge, but when aberrantly regulated, drive pathogenic antibody formation in autoimmunity and undergo neoplastic transformation in angioimmunoblastic T-cell lymphoma and other primary cutaneous T-cell lymphomas. Limited information is available on the expression and regulation of genes in human Tfh cells. Using a fluorescence-activated cell sorting-based strategy, we obtained primary Tfh and non-Tfh T effector cells from tonsils and prepared genome-wide maps of active, intermediate, and poised enhancers determined by chromatin immunoprecipitation-sequencing, with parallel transcriptome analyses determined by RNA sequencing. Tfh cell enhancers were enriched near genes highly expressed in lymphoid cells or involved in lymphoid cell function, with many mapping to sites previously associated with autoimmune disease in genome-wide association studies. A group of active enhancers unique to Tfh cells associated with differentially expressed genes was identified. Fragments from these regions directed expression in reporter gene assays. These data provide a significant resource for studies of T lymphocyte development and differentiation and normal and perturbed Tfh cell function.
Structural and Morphological Properties of CuInS2 Polycrystalline Films Obtained By Spray Pyrolysis Method (2005)

CuInS2 semiconductor films were prepared at three substrate temperatures on glass substrates by spray pyrolysis method. The X-rays diffraction (XRD) spectra of the films have shown that the films produced are polycrystalline and chalcopyrite in structure. The texture coefficients were evaluated for different substrate temperatures. Scanning electron microscopy (SEM) surface micrographs show different morphologies of the surface grains, which are dependent on temperature.
Microconvective Thermal Conductivity in Disperse Two-Phase Mixtures as Observed in a Low Velocity Couette Flow Experiment (1981)

Eddy transport associated with microscopic flow fields in shearing two-phase flows was investigated. Although such microconvective effects are expected to be present in all disperse two-phase flows, usually they are masked by other collateral mechanisms and could not be studied critically. In the present study, effective thermal conductivities of neutrally buoyant solid-fluid mixtures were measured in a rotating Couette flow apparatus. Low Reynolds numbers were used to avoid the effects of turbulence. Significant enhancement in effective thermal conductivity was observed when the Ped were high. Here Ped = ed2/αf where e is the local mean shear rate, d is the particle diameter, and αf is the thermal diffusivity of the fluid. Volume fractions employed were φ = 0.15 and 0.30 for polyethylene beads (2.9 mm in diameter) in a mixture of silicone oil and kerosene, and φ = 0.15 for polystyrene particles (0.3 mm in diameter) in a mixture of silicone oil and Freon-113. Single-phase liquid mixtures were also measured in various shear rates to show that the thermal conductivity was independent of shear rate and hence the observed phenomenon was not an instrumental artifact. The dependence of conductivity on particle Peclet number appeared to approach a power law relationship ke ∝ Ped1/2 for high Peclet numbers (300 < Ped < 2000).
Compiling distribution directives in a Fortran 90D compiler (2002)

Data partitioning and mapping is one of the most important steps of writing a parallel program, especially a data parallel one. Recently, Fortran D, and subsequently, High Performance Fortran (HPF) have been proposed to allow users to specify data distributions and alignments for the arrays in their programs. The paper presents the design of the data partitioning module of Fortran 90D compiler that processes the alignment and distribution directives.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Bacterial plasminogen receptors: in vitro evidence for a role in degradation of the mammalian extracellular matrix (1995)

The potential of bacterium-bound plasmin to degrade mammalian extracellular matrix and to enhance bacterial penetration through basement membrane was assessed with the adherent strain SH401-1 of Salmonella enterica serovar Typhimurium. Typhimurium SH401-1 was able to bind plasminogen and to enhance the tissue-type plasminogen activator-mediated activation of the single-chain plasminogen to the two-chain plasmin. The end product, the enzymatically active, bacterium-bound plasmin activity, was also formed in a normal human plasma milieu in the presence of exogenous tissue-type plasminogen activator, indicating that plasmin was protected from the plasminogen activator inhibitors and plasmin inhibitors of plasma. Plasmin bound on Typhimurium cells degraded 125I-labeled laminin as well as 3H-labeled extracellular matrix prepared from the human endothelial cell line EA.hy926. The degradations were not seen with Typhimurium cells without plasminogen and were inhibited by the low-molecular-weight plasmin inhibitor aprotinin. Plasmin bound on Typhimurium cells also potentiated penetration of bacterial cells through the basement membrane preparation Matrigel reconstituted on membrane filters. The results give in vitro evidence for degradation of the mammalian extracellular matrix by bacterium-bound plasmin and for a pathogenetic role for bacterial plasminogen receptors.
Liver iron stores in patients with secondary haemosiderosis under iron chelation therapy with deferoxamine or deferiprone (1995)

Total body iron stores including liver and spleen iron were assessed by non-invasive SQUID biomagnetometry. The liver iron concentration was measured in groups of patients with beta-thalassaemia major or other posttransfusional siderosis under treatment with the oral iron chelator deferiprone (n = 19) and/or with parenteral deferoxamine (n = 33). An interquartile range for liver iron concentrations of 1680-4470 micrograms/g liver was found in these patients. In both groups a poor correlation between liver iron and serum ferritin values was observed. Repeated measurements of liver and spleen iron concentrations as well as determination of liver and spleen volume by sonography were performed in six patients under continuous deferiprone treatment for 3-15 months. In this group detailed information was obtained on the whole body iron store (5-36g) and the iron excretion rates (14-34 mg/d) for each patient. As indicated by decreasing liver iron concentrations, five out of six subjects showed a negative iron balance (2-13 mg/d). Conventional measurements of both serum ferritin and urine iron excretion gave fluctuating results, thus being only of limited use in the control of iron depletion therapy. The non-invasive biomagnetic liver iron quantification is a precise and clinically verified technique which offers more direct information on the long-term efficacy of an iron depletion therapy than the hitherto used methods. This technique may be of use in the clinical evaluation of new oral iron chelators.
Band offsets of Al2O3/InxGa1−xAs (x=0.53 and 0.75) and the effects of postdeposition annealing (2010)

Band offsets at the interfaces of InxGa1−xAs/Al2O3/Al where x=0.53 and 0.75 were determined by internal photoemission and spectroscopic ellipsometry. The photoemission energy threshold at the InxGa1−xAs/Al2O3 interface was found to be insensitive to the indium composition but shifted to a lower energy after a postdeposition annealing at high temperatures. Subthreshold electron photoemission was also observed for the annealed sample and was attributed to interfacial layer formation during the annealing process.
An open-loop programmable amplifier with a maximum gate-bandwidth product of 1GHz (1981)

An amplifier with a gain-bandwidth product up to 1GHz using localized positive feedback and nonlinearity correction will be reported. Linearity for a 1V p-p output signal is 0.1% over a gain range that is externally programmable from zero to above 100.
Reactive crystal growth in two dimensions: Silicon nitride on Si(111) (1995)

The nitridation of the Si(111) surface by reaction with ${\mathrm{NH}}_{3}$ was studied by low-energy electron microscopy (LEEM), low-energy electron diffraction (LEED), and scanning tunneling microscopy (STM). Reaction layers with periodicities of (8\ifmmode\times\else\texttimes\fi{}8), (8/3\ifmmode\times\else\texttimes\fi{} 8) / 3 ), (3/4\ifmmode\times\else\texttimes\fi{} 3) / 4 ), and (3 \ensuremath{\surd}3 /4\ifmmode\times\else\texttimes\fi{}3 \ensuremath{\surd}3 /4) were observed depending on the temperature of nitridation and duration of electron-beam exposure. The nucleation and growth of the nitride layer on well-oriented and miscut Si(111) surfaces were observed by STM and followed in real time by video LEEM. The (8\ifmmode\times\else\texttimes\fi{}8) nitride islands nucleate and grow in the same manner as the (7\ifmmode\times\else\texttimes\fi{}7) domains, with the apex of the triangle pointing in the [1\ifmmode\bar\else\textasciimacron\fi{} 1\ifmmode\bar\else\textasciimacron\fi{}2] direction away from the step into the upper terrace. On the miscut surface, (8\ifmmode\times\else\texttimes\fi{}8) nitride growth proceeds with widening of the terraces and step bunching. The (3/4\ifmmode\times\else\texttimes\fi{} 3) / 4 ) multiplet structure, on the other hand, nucleates randomly on comtaminated sites on the surface, or evolves directly from the (8\ifmmode\times\else\texttimes\fi{}8) structure.
