Perceptual quality estimation of H.264/AVC videos using reduced-reference and no-reference models (2016)

Reduced-reference (RR) and no-reference (NR) models for video quality estimation, using features that account for the impact of coding artifacts, spatio-temporal complexity, and packet losses, are proposed. The purpose of this study is to analyze a number of potentially quality-relevant features in order to select the most suitable set of features for building the desired models. The proposed sets of features have not been used in the literature and some of the features are used for the first time in this study. The features are employed by the least absolute shrinkage and selection operator (LASSO), which selects only the most influential of them toward perceptual quality. For comparison, we apply feature selection in the complete feature sets and ridge regression on the reduced sets. The models are validated using a database of H.264/AVC encoded videos that were subjectively assessed for quality in an ITU-T compliant laboratory. We infer that just two features selected by RR LASSO and two bitstream-based features selected by NR LASSO are able to estimate perceptual quality with high accuracy, higher than that of ridge, which uses more features. The comparisons with competing works and two full-reference metrics also verify the superiority of our models.
Intravenous Iloprost treatment for severe bone pain caused by sickle cell crisis (2004)

In sickle cell disease (SCD), HbS can form rigid polymers, lead-ing to the characteristic sickle form of red blood cells whenexposed to a low oxygen environment (1). Massive polymerisa-tion induces blood flow disturbances, abnormal erythrocyteadhesion, platelet activation and endothelial cell dysfunction (1-3). Acute sickle cell crisis results from these haemodynamicdisturbances, leading to various complications in differentorgans. In bone, arterial or venous vessel occlusion associatedwith a limitation in collateral circulation can cause tissuedestruction, resulting in structural collapse due to mechanicalstress (4-8). A surrounding bone marrow oedema (BME) is asign of ischaemic cell damage and consecutive tissue exertion inthis process. Several agents have been used to enhance osseousblood flow, but only limited success has been achieved (9).Therapeutic intervention is at present limited to analgesia andsurgical treatment, such as core decompression or arthroplastyin advanced stages.

Modeling Adaptive Middleware and Its Applications to Military Tactical Datalinks (2012)

Open systems solutions and techniques have become the de facto standard for achieving interoperability between disparate, large-scale, legacy software systems. A key technology among open systems solutions and techniques is middleware. Middleware, in general, is used to isolate applications from dependencies introduced by hardware, operating systems, and other low-level aspects of system architectures. While middleware approaches are or will be integrated into operational military systems, many open questions exist about the appropriate areas to applying middleware. Adaptive middleware is middleware that provides an application with a run-time adaptation strategy, based upon system-level interfaces and properties. Adaptive middleware is an example of an active applied research area. Adaptive middleware is being developed and applied to meet the ever-increasing challenges set forth by the next generation of mission-critical distributed real-time and embedded (DRE) systems. The driving force behind many next-generation DRE systems is the establishment of QoS requirements typically associated with workloads that vary dynamically. The Weapon System Open Architecture (WSOA), an adaptive middleware platform developed by Boeing, is modeled as a part of this research to determine the scalability of the architecture. The WSOA adaptive middleware was previously flight-tested with one tactical node, and the test results represent the performance baseline the architecture. The WSOA adaptive middleware is modeled with 1, 2, 4, 8 and 16 tactical nodes. The results of the modeling and simulation is that the WSOA adaptive middleware can achieve the performance baseline achieved during the original flight-test, in the cases of 1, 2, and 4 tactical nodes. In addition, the results of the modeling and simulation also demonstrate that the WSOA adaptive middleware cannot achieve
Structure and dynamics of water channels inside self-assembling dipeptide nanotubes (2002)

Recently, Kato and co-workers [1] prepared supramolecular liquid crystals. For example, doubly hydrogen-bonded supramolecular liquid-crystalline complexes (low molecular weight and polymeric complexes) derived from 2,6bis(amino)pyridines and carboxylic acids were shown to exhibit smectic phases. These molecular materials show a variety of mesomorphic properties and assembled structures with potential usefulness for generation of novel materials. However, there is not yet any crystallographic evidence supporting the findings on these assembled structures. As an initial approach, we were prompted to investigate the molecular structures of low molecular weight complexes between 2,6-di(acylamino)pyridines (nAPy, n = number of carbon atoms in the alkyl chain) and alkoxybenzoic acids (guests). It is of relevance, therefore, in the context of crystal engineering and supramolecular architecture and as part of our preliminary work to investigate the hydrogen bonding network and crystal packing of nAPy (hosts) molecules. Presently, we have determined series of crystal structures of nAPy (n = 1,2,3,4 and 5) using X-ray diffraction techniques. The crystals were grown from hexane/ethylacetate mixed solvents by slow evaporation method. The crystal structures analyses revealed that the driving force that controls the molecular aggregation of 2,6di(acylamino)pyridines is mainly by N-H ... O hydrogen bonding. Both NH groups in nAPy are intermolecularly hydrogen-bonded to the amide carbonyl groups in an intriguing ribbon-like pattern. The crystal packing and molecular aggregation modes are dependent on the length of alkyl chain. Research studies on complexes of nAPy with alkoxybenzoic acids is now in progress.
Dogs L. infantum infection from an endemic region of the north of Tunisia: a prospective study. (2008)

A follow-up study of 917 dogs was undertaken between 1994 and 1995 in the focus of visceral leishmaniasis in northern Tunisia. It permitted to assess the demography of the dog population, the importance of canine leishmaniasis (CL) and the determinants of seropositivity and mortality of dogs. Canine population was stable through time with an input of 231 dogs and an output of 218 dogs per year. The prevalence of seropositivity was 18% and 22.3% in 1994 and 1995 respectively and 90% of dogs were asymptomatic. Among 525 negative dogs in 1994 and reassessed in 1995, 78 seroconverted revealing an annual cumulative incidence of 14.74%. On the other hand, 23.47% (27/115) of seropositive dogs became negative in 1995. Age, presence of symptoms and density of dogs were independently associated with CL seropositivity. These results demonstrate the difficulty of control strategies of visceral leishmaniasis targeting the dog population.
Spectral characterization of mammographic tissue for computer aided diagnosis of malignant masses (2002)

An approach for the analysis of the spectral properties of digitized mammograms for computer aided diagnosis is presented. The approach is developed using 206 regions of interest (ROIs) extracted from 103 normal and 103 malignant mass cases selected from the Digital Database for Screening Mammography (DDSM) available from the University of South Florida. A spectral definition is proposed in terms of a linear function of the local slope of the modified, circularly averaged periodogram across the entire spectrum. The local slope is estimated in a least squares sense for each point in the spectrum as a function of local neighboring samples. The proposed spectral definition is evaluated for the discrimination of malignant versus normal ROIs. Results are summarized by receiver operating characteristic (ROC) curve analysis. For the cases studied, maximum detection performance is achieved with an area under the ROC curve (AUC) of 0.9223 and a partial AUC at 90% sensitivity of 0.712. These results suggest that the proposed spectral signature is useful as a computationally fast and effective approach for the characterization of malignant masses in digitized mammograms.

Divergent Multicomponent Tandem Palladium‐Catalyzed Aminocarbonylation‐Cyclization Approaches to Functionalized Imidazothiazinones and Imidazothiazoles (2015)

Abstract The reactivity of 2‐(prop‐2‐ynylthio)imidazoles under PdI 2 /KI‐catalyzed oxidative aminocarbonylation conditions has been studied. Under relatively mild conditions, 0.33–1 mol % of catalyst at 100 °C in MeCN and under 20 atm (at 25 °C) of a 4:1 mixture of CO/air, and in the presence of an equimolar amount of a secondary nucleophilic amine, substrates that are unsubstituted or bear a single substituent on the imidazole ring were converted directly in a multicomponent fashion into functionalized imidazothiazinones. This transformation occurred through a new auto‐tandem catalysis process that involves two concatenated catalytic cycles both catalyzed by PdI 2 : oxidative aminocarbonylation of the terminal triple bond/cyclocarbonylation. However, in the presence of an excess of secondary amine, 4,5‐disubstituted substrates led selectively to functionalized imidazothiazoles through an oxidative aminocarbonylation/conjugate addition process.
Synthesis of Saint Louis Encephalitis Virus Ribonucleic Acid in BHK-21/13 Cells (1969)

Infection of baby hamster kidney cells (BHK-21/13) with Saint Louis encephalitis (SLE) virus depressed the rate of protein and ribonucleic acid (RNA) synthesis until viral RNA synthesis began 6 hr postinfection (PI). Virus-directed RNA synthesis was subsequently inhibited until 12 hr PI when virion maturation began. The rate of protein synthesis reached a peak 6 hr PI and was subsequently depressed until just before the onset of virion maturation. Density gradient analysis of phenol-extracted RNA from actinomycin-treated infected cells indicated that, at 6 to 8 hr and again at 12 to 20 hr PI, three species of viral-specific RNA were synthesized. The most rapid sedimenting form (43S) was ribonuclease-sensitive and had a base composition similar to the RNA isolated from mature virions. The 20S RNA species was ribonuclease-resistant and had a sedimentation coefficient and base composition similar to the replicative form associated with other arbovirus infections. The 26S RNA was ribonuclease-resistant (0.2 mug/ml, 0.1 m NaCl, 25 C, 30 min) and had a nucleotide base composition closer to the 20S form than to the values for 43S RNA. Five-minute pulse labeling of infected cultures during the period viral RNA synthesis was maximal resulted in labeling of only the 20S to 22S RNA fractions. With pulse-labeling periods of 10 min, both the 20S and 26S RNA species were radioactive. Periods of radioactive labeling of as long as 15 min were required before the 43S form was radioactively labeled. These results suggest that the 20S and 26S RNA may be intermediate forms in the synthesis of 43S viral RNA.
The Effect of 1.6 GHz Radiation on Neurotransmitters in Discrete Areas of the Rat Brain. (1976)

Rats were exposed to 1.6 GHz radiation at a measured power density of 80 mW/sq cm for 10 minutes. Rectal temperature rise was 4 deg c. Hyperthermal control rats were exposed to warm air environment to raise core temperature 4 deg c. Hypothalamic norepinephrine was decreased in the irradiated and hyperthermal animals compared to the normothermal controls. Hippocampal serotonin was decreased in the irradiated but not in the hyperthermal animals as was the dopamine content of the corpus striatum and hypothalamus. The changes noted fit well with power distribution determined by thermographic imagery of irradiated rats, and indicate that these changes are the result of the microwave-induced hyperthermia.

IL-10 Mediates Resistance to Adoptive Transfer Experimental Autoimmune Encephalomyelitis in MyD88−/− Mice (2009)

MyD88 is an adaptor molecule that functions in the innate signaling induced by proinflammatory adjuvants that interact with TLRs. Mice lacking MyD88, for example, resist active experimental autoimmune encephalomyelitis (EAE) induced by immunization with an encephalitogenic myelin oligodendrocyte glycoprotein (MOG) peptide in CFA. We reasoned that MyD88(-/-) mice, nevertheless, should be susceptible to EAE mediated by adoptive transfer of activated encephalitogenic T cell lines, which do not require adjuvant signaling for their effector functions. We now report, however, that mice lacking MyD88 also resist adoptive EAE mediated by an anti-MOG T cell line that is strongly encephalitogenic in wild-type (WT) mice. The transferred anti-MOG T cells proliferated, secreted INF-gamma, and migrated to the CNS in the MyD88(-/-) mice, as they did in WT mice, but inflammatory infiltrates did not progress and clinical EAE did not develop. The resistance of the MyD88(-/-) mice to adoptive EAE mediated by the otherwise encephalitogenic T cells was found to result from the secretion of IL-10 by recipient T cells of two different specificities: those specific for MOG and those responding to the T cell clone itself-both anticlonotypic and antiergotypic T regulators were detected. IL-10-producing anti-MOG T cells isolated from immunized MyD88(-/-) mice suppressed the induction of active EAE in WT recipients. Moreover, the absence of IL-10 production in MyD88/IL-10 double-knockout mice rendered the mice susceptible to adoptive transfer of EAE. Thus, MyD88 signaling appears to be a key factor in determining the cytokine phenotype of T cells involved in autoimmune inflammation and regulation.
Probiotics as efficient immunopotentiators: translational role in cancer prevention. (2013)

Accumulating evidences indicate that some diseases are triggered by abnormalities of the gut microbiota. Among these, immune-related diseases can be the promising targets for probiotcs. Several studies have proved the efficacy of probiotics for preventing such diseases including cancers, infections, allergies, inflammatory bowel diseases and autoimmune diseases. Lactobacillus casei strain Shirota (LcS) is one of the most popular probiotics, benefits of which in health maintenance and disease control have been supported by several science-based evidences. This review summarizes human clinical trials with this probiotic against cancer development and also discusses the possible immunomodulatory mechanisms by which LcS exerts anti-cancer activity.
Determination of the Protective Effects of Neutralizing Anti‐Hepatitis B Virus (HBV) Immunoglobulins by Epitope Mapping with Recombinant HBV Surface‐Antigen Proteins (2000)

Anti-hepatitis B virus (HBV) surface-antigen immunoglobulins prepared from human sera are clinical reagents which have been approved for prophylactic treatment in HBV-exposed persons. The passive immunoprophylaxis with immunoglobulins is meant to cross-link viral particles, which are then further cleared by the host's own immune system. While antibodies specific for both anti-S- and anti-preS proteins have been proved to serve as effective anti-viral agents, so far the fine antigen specificity of clinical immunoglobulin preparations has not been determined. Using recombinant proteins covering the hepatitis B surface antigen, in the present study, the specificity of a commercially available immunoglobulin preparation was determined and immunodominant epitopes were mapped. Here, it is shown that the major reactivity of anti-HBV immunoglobulins is directed against the S-protein, and that no reactivity to the preS2 but a weak binding activity to the preS1 region was detectable. The antigen reactivity within the preS1 region was biased to the C-terminal region, which indicates the presence of a putative B-cell epitope. The evaluation of the antigen specificity and determination of novel protective epitopes will provide valuable information for the further development and improvement of prophylactic HBV immunoglobulins.
MPL-net at ARM Sites (2002)

The NASA MPL-net project goal is consistent data products of the vertical distribution of clouds and aerosol from globally distributed lidar observation sites. The four ARM micro pulse lidars are a basis of the network to consist of over twelve sites. The science objective is ground truth for global satellite retrievals and accurate vertical distribution information in combination with surface radiation measurements for aerosol and cloud models. The project involves improvement in instruments and data processing and cooperation with ARM and other partners.
Effects of light and atmospheric carbon dioxide enrichment on photosynthesis and carbon partitioning in the leaves of tomato (<i>Lycopersicon esculentum</i> L.) plants over-expressing sucrose phosphate synthase (1995)

Abstract Photosynthetic carbon assimilation, carbon partitioning and foliar carbon budgets were measured in the leaves of transformed tomato plants expressing a maize sucrose-phosphate synthase (SPS) gene in addition to the native enzyme, and in untransformed controls. The maize SPS gene was expressed under control of either the promoter of the small subunit of ribulose 1,5-bisphosphate carboxylase (rbcS promoter; lines 2, 9 and 18) or the 35S promoter from cauliflower mosaic virus (CaMV promoter; line 13). The rate of sucrose synthesis was increased relative to that of starch and sucrose/starch ratios were higher throughout the photoperiod in the leaves of all plants expressing high SPS activity. The leaf carbon budget over the day/night cycle in air at low irradiance (180μmol photon m−2 s−1) was similar in all plants. Net photosynthesis measured in air and at elevated CO2 (800–1500 μl l−1) on whole plants grown in air at 400μmol m−2 s−1 irradiance was significantly increased in the high SPS expressors compared to the untransformed controls and was highest where SPS activity was greatest. At high CO2 the stimulation of photosynthesis was more pronounced. We conclude that SPS activity is a major point of control of photosynthesis particularly under saturating light and CO2.
