Polyhedral parallelization of binary code (2012)

Many automatic software parallelization systems have been proposed in the past decades, but most of them are dedicated to source-to-source transformations. This paper shows that parallelizing executable programs is feasible, even if they require complex transformations, and in effect decouples parallelization from compilation, for example, for closed-source or legacy software, where binary code is the only available representation. We propose an automatic parallelizer, which is able to perform advanced parallelization on binary code. It first parses the binary code and extracts high-level information. From this information, a C program is generated. This program captures only a subset of the program semantics, namely, loops and memory accesses. This C program is then parallelized using existing, state-of-the-art parallelizers, including advanced polyhedral parallelizers. The original program semantics is then re-injected, and the transformed parallel loop nests are recompiled by a standard C compiler. We show on the PolyBench benchmark suite that our system successfully detects and parallelizes almost all the loop nests from the binary code, using a recent polyhedral loop parallelizer as a backend. The paper ends by elaborating a strategy to parallelize more complex programs, such as those containing non-linear accesses to memory, and provides a few example case-studies.

Effects of Reserpinization, Surgical Denervation and in vitro Chemical Denervation with 6-Hydroxydopamine on the Contractile Response of Isolated Rabbit Ear Artery to Propranolol (1981)

The contractile effect of propranolol in isolated rabbit ear artery was assessed in reserpinized and in surgically and chemically denervated blood vessels. Reserpinization and surgical denervation either had no effect on or enhanced the ear artery contractile response to 10(-6) to 10(-4) M propranolol. In contrast, the contractile response to propranolol was nearly abolished after denervation of the ear artery in vitro with 6-hydroxydopamine (6-OHDA). Dose-response curves to norepinephrine were shifted to the left by factors of 4.9 in 6-OHDA denervated ear arteries and 15.6 in untreated arteries in the presence of 10(-7) M desipramine. The diluent for 6-OHDA shifted both the norepinephrine and propranolol dose-response curves to the right. It is proposed that propranolol caused a contractile response in ear artery by an action on the postsynaptic tissues of this vessel. 6-OHDA denervation caused nonspecific desensitization in rabbit ear artery leading to the loss of response of this vessel to propranolol.
Effect of interface in bilayer polydiphenylenephthalide film on electron transport (2012)

The results of studies of multilayer film structures based on a wide-gap polymer using the time of flight technique are shown. Experimental data showed that transport of charge carriers depends strongly on the presence of a polymer/polymer interface. The possibility is shown of increasing the threshold thickness of the experimental structure, in which effects of switching to a highly conducting state induced by uniaxial mechanical pressure are also found. Preliminary interpretation of the obtained data is performed.

Inverse-kinematics-based control of a redundantly actuated platform for rehabilitation (2008)

The paper introduces the control of a redundantly actuated parallel mechanism for ankle rehabilitation which is based on online inverse kinematics calculation to generate required actuating parameters to control the mechanism and achieve the required dynamic response. The geometry of the mechanism is described and the design parameters are investigated in the analysis of singularity and dexterity. The dynamic model is developed and the tuning of the control gains is performed by analysing the level of actuation conflict and tracking error that have been minimized by varying the controller parameters. The paper further examines the actuation conflict and evaluates its association with the control parameters. Both simulation and experiments were carried out to implement the analysis and control strategy in the mechanism.
Effect of a mild exercise program on myocardial function and the development of hypertrophy (1979)

Cardiac function and the development of myocardial hypertrophy were studied in rats conditioned by an exercise program consisting of 8 wk of running on a treadmill. At the end of the training period a group of exercised and sedentary rats was subjected to hemodynamic evaluation under general anesthesia. Except for a slight elevation in the heart rates of the exercised animals there were no significant differences between the exercised and sedentary rats at rest. Following an increase in afterload or a period of hypoxia, the cardiac index of the exercised animals remained significantly higher than that of the sedentary controls. These differences were related to changes in stroke volume. Another group of exercised and sedentary animals underwent either constriction of the ascending aorta or a sham operation. Sedentary rats developed significant hypertrophy at 3 days but had no hypertrophy at 1 day after aortic constriction. Exercised rats, however, developed significant myocardial hypertrophy by 1 day after pressure overload. These data suggest that the heart from an exercised animal is better able to tolerate increases in afterload and hypoxia and can respond with compensatory myocardial hypertrophy more rapidly than the heart of a sedentary animal.

Electrolytes Containing Fluorinated Ester Co-Solvents for Low-Temperature Li-Ion Cells (2008)

The fluorinated esters 2,2,2-trifluoroethyl butyrate (TFEB), 2,2,2-trifluoroethyl acetate (TFEA), ethyl trifluoroacetate (ETFA), and methyl pentafluoropropionate (MPFP) are added to carbonate-based electrolyte solvents in varying amounts to improve the low temperature performance and high temperature resiliency of lithium-ion cells. These fluorinated ester co-solvents are also anticipated to improve the safety characteristics, film forming properties and physical properties. Reported within this paper are results on the electrochemical characterization and charge/discharge characteristics of MCMB-LiNixCo1-xO2 the cells that contain various fluorinated ester-containing electrolytes. Results obtained showed that the cell containing the electrolyte consisting of 1.0 M LiPF6 in 20:60:20 v/v% ethylene carbonate (EC)/ethyl, methyl carbonate (EMC)/ TFEB had the best performance of all the fluorinated ester containing mixtures investigated in nearly all tests, and also performed comparably to the baseline carbonate only mixtures.
Effects of nitrogen availability and spore concentration on the biocontrol activity of Ascochyta caulina in common lambsquarters (Chenopodium album) (2002)

Common lambsquarters is an annual weed of many important crops. Ascochyta caulina is a plant pathogenic fungus that causes necrotic lesions on the leaves and stems of common lambsquarters. The objective of the present study was to estimate the effect of plant N supply on the biocontrol activity of A. caulina isolates against common lambsquarters. In greenhouse experiments replicated groups of common lambsquarters plants raised with different N supplies were sprayed with various isolates and concentrations of A. caulina 3 wk after planting. Height, number of leaves, total leaf area, fresh and dry weight, and tissue N concentration of common lambsquarters 4 wk after emergence increased significantly with increasing N supply. Disease development was positively related to increasing plant tissue N and also to increasing spore concentration. Fungal spore concentration also had a positive effect on the plant tissue N percentage. Ascochyta caulina isolate W90-1 caused a greater dry weight reduction in common lambsquarters than isolates I-001 and NW-6 did.
Limited magnitude error detecting codes over Z<inf>q</inf> (2009)

The error detecting problem for limited magnitude errors over high radix channels is studied. In this error model, the error magnitude does not exceed a certain limit known beforehand. For asymmetric and unidirectional channels, both all and t error detecting codes are studied. Further, close-to-optimal codes are proposed. For symmetric channels, optimal all error detecting codes are given.

Suppression of in vitro Epstein-Barr virus infection: a new role for adult human T-lymphocytes. (1978)

In vitro EBV infection of lymphocytes from different sources indicated that B-cells of adult peripheral or fetal cord blood transform with equal efficiency whether assayed by DNA synthesis induction or immortalization. Unfractionated adult lymphocytes transformed much less efficiently than those from fetal cord blood. This effect was due to the suppression of B-cell proliferation by adult T-lymphocytes.

Mutation of Chlorophyll Ligands in the Chlorophyll-Binding CP47 Protein As Studied in a Synechocystis sp. PCC 6803 Photosystem I-less Background (1994)

Site-directed mutations have been introduced to replace conserved histidine residues in the chlorophyll-binding protein CP47 of photosystem II (PS II) in a PS I-less/apcE-background strain of the cyanobacterium Synechocystis sp. PCC 6803. In thylakoids isolated from such a system, the degree of loss of the 695-nm fluorescence emission maximum at 77 K compared to that at 685 nm generally was consistent with the decrease in oxygen evolution rates measured at saturating light intensity. Taking into account that in the absence of CP47 and PS I some chlorophyll remains detectable in cells, the relative 695-nm fluorescence emission and the rate of oxygen evolution also correlate with the relative amount of chlorophyll per cell and with the number of PS II reaction centers on a chlorophyll basis. Interestingly, the 77 K fluorescence excitation spectra monitoring 695-nm emission of thylakoids from the CP47 His-to-Tyr mutants in a photosystem I-less/apcE-background showed increases in the 413- and 531-nm absorption regions, compared to spectra of thylakoids from the background strain. These wavelengths coincide with absorption maxima of pheophytin. No increase in the 531-nm excitation band was observed in thylakoids from mutants lacking PS II or with a His-to-Asn mutation. These results are interpreted to indicate that replacement of conserved histidine residues by tyrosine in CP47 leads to the loss of Mg2+ from chlorophyll, resulting in the formation of pheophytin, or to the binding of pheophytin (rather than chlorophyll) at a particular pigment-binding site of CP47 during biogenesis and assembly of the protein. It was observed that the light-harvesting efficiency of CP47 His mutants was lower judging from the light intensity dependence of electron transport and analysis of fluorescence decay kinetics. This suggests that the presence of pheophytin in the antenna decreases antenna efficiency.
Comparison of biooxidation with carbon dioxide assimilation during bacterial growth on ferrous ion or elemental sulfur (2001)

Biomass and oxygen uptake activity profiles of a mixed bioleaching culture were studied and compared at various temperatures. Bacteria were grown on ferrous ion or elemental sulfur in a Micro-Oxymax respirometer apparatus that allowed measurement of both oxygen consumption and carbon dioxide assimilation. Balanced growth was observed between 10 degrees C and 35 degrees C, with an optimum at 30 degrees C, on both energy sources. No significant growth was observed at the lowest temperature used, 5 degrees C, or at the highest temperature used, 40 degrees C. The oxygen to carbon dioxide molar yield was 50:1 when growing on ferrous ion but only 17:1 when growing on elemental sulfur. Upon transfer from a sulfide ore to a new energy source, greater numbers in the inoculum reduced the duration of the lag phase. Lag phase duration was also reduced by proximity to the optimum growth temperature. A longer lag phase decreased the achievable growth rate of the cells exponentially, significantly affecting biooxidation activity.
Synthesis and Application of Poly(ionic liquid) Based on Cardanol as Demulsifier for Heavy Crude Oil Water Emulsions (2017)

Amphiphilic poly(ionic liquids), PILs, derived from natural products attracted great attention as a green chemical in the field of the surface chemistry and petroleum industry. In the present work, new surface active PILs were synthesized from cardanol cashew nut oil as a hydrophobic alkyl phenol. The phenol group was etherified with diethanolamine, ethanolamine, and tetraethylene glycol using linking agent based on β,β-dicholorodiethyl ether to insert nonionic hydrophilic groups into cardanol. The amine group was quaternized with 2-acrylamido-2-methyl-1-propanesulfonic acid to produce polymerizable ionic liquids that polymerized to obtain new PILs. The chemical structure of the prepared new PILs was elucidated from 1HNMR and elemental analysis. The surface activity of the prepared PILs was determined from the surface and interfacial tension measurements of their aqueous solution. The ability of the prepared PILs to disperse the asphaltene fractions of the heavy Arabian crude oil was studied. It was used to explain their demulsification performance and efficiency data when they were used as demulsifiers for crude oil water emulsions. The demulsification data elucidate that the PILs have greater ability to reduce IFT and can separate water effectively. Moreover, the PILs have a greater tendency to disperse asphaltene and perform better as demulsifier than that flocculate asphaltenes.

Structural and Functional Analysis of ProQ:  An Osmoregulatory Protein of <i>Escherichia coli</i> (2007)

Transporter ProP of Escherichia coli senses extracellular osmolality and responds by mediating cytoplasmic accumulation of organic solutes such as proline. Lesions at the proQ locus reduce ProP activity in vivo. ProQ was previously purified and characterized. Homology modeling predicted that ProQ possesses an alpha-helical N-terminal domain (residues 1-130) and a beta-sheet C-terminal domain (residues 181-232) connected by an unstructured linker. In this work, we tested the structural model for ProQ, explored the solubility and folding of full length ProQ and its domains in diverse buffers, and tested the impacts of the putative ProQ domains on ProP activity in vivo. Limited tryptic proteolysis of ProQ revealed protease resistant fragments corresponding to the predicted N-terminal and C-terminal domains. Polypeptides corresponding to the predicted N- and C-terminal domains could be overexpressed and purified to near homogeneity using nickel affinity, size exclusion and reversed phase chromatographies. Circular dichroism spectroscopy of the purified proteins revealed that the N-terminal domain was predominantly alpha-helical, whereas the C-terminal domain was predominantly beta-sheet, as predicted. The domains were soluble and folded in neutral buffers containing 0.6 M NaCl. The N-terminal domain was soluble and folded in 0.1 M MES (2-[N-morpholino]-ethane sulfonic acid) at pH 5.6. Despite high solubilities, the proteins were not well folded in Na citrate (0.1 M, pH 2.3). The ProQ domains and the linker were expressed at physiological levels, singly and in combination, in bacteria lacking the chromosomal proQ locus. Among these proteins, the N-terminal domain could partially complement the proQ deletion. The full length protein and a variant lacking only the linker restored full activity of the ProP protein.
Photochemically Implemented Metal/Polymer Nanocomposite Materials for Advanced Optical Applications (2011)

In this context, the photoinduced synthesis has many advantages since it combines the characteristic features of light activation i.e. versatility and convenience of the process, high spatial resolution and reaction controllability (intensity and wavelength), with the simplicity of the colloidal approach. Various photo-induced synthetic strategies to obtain metal nanoparticles in a variety of conditions have been described by However, photoassisted processes allowing the generation of polymer/metal nanocomposites that were introduced very recently are still in demand of further investigation.
Internal cooling passage heat transfer near the entrance to a film cooling hole - Experimental and computational results (1992)

Detailed heat transfer measurements were made near the entrance to a single film cooling hole using a transient liquid crystal technique in a large scale (100X) model. The hole inclination angle and flow extraction rate were varied across a range representative of actual engine conditions. Local values of heat transfer were found to exceed 6 times the levels associated with fully developed, turbulent channel flow. The region of maximum heat transfer enhancement occurred downstream of the hole entrance. Computational and experimental flow diagnostics were performed to investigate the mechanisms responsible for the observed heat transfer distributions. The removal of the upstream boundary layer and the downwash created by a vortex pair were found to be important phenomena.Copyright © 1992 by ASME

Observations on the influence of exogenous gonadotrophins and cloprostenol on ovulation in gilts. (1991)

We studied the effects of gonadotrophins and prostaglandin (PG) F(2alpha) on ovulation in gilts. Twenty-eight gilts were induced to ovulate using 750 IU pregnant mares serum gonadotrophin (PMSG) and 500 IU human chorionic gonadotrophin (hCG), administered 72 h apart. At 34 and 36 h after hCG, gilts received injections of either 500 mug or 175 mug PGF(2alpha) (cloprostenol), or had no injections. Laparotomies were performed at 36 h (cloprostenol gilts) or 38 h (controls) after hCG injection. The ovaries were examined and the proportion of preovulatory follicles that had ovulated (ovulation percent) was determined at 30 min intervals for up to 6 h. The number of gilts in which ovulation was initiated and the ovulation percent increased (p<0.001) with time, but was not affected by treatment. Many medium sized follicles (</=6 mm) were also observed to ovulate, or to exhibit progressive luteinization without overt ovulation, during the surgical period. A discrepancy between numbers of preovulatory follicles and corpora lutea suggests that luteal counts may not be an accurate assessment of ovulation rate following gonadotrophic stimulation.
Merging of Galaxies with Central Black Holes. I. Hierarchical Mergings of Equal-Mass Galaxies (1996)

We have investigated the merging of galaxies with central, massive black holes. We performed simulations of hierarchical mergings, in which the merger remnant of one simulation is used as the progenitor for the next simulation. Our main results are the following: First, the central part of the merger has a very shallow density cusp (ρ is proportional to r^-α^, with α <~ 51). This result is in good agreement with recent Hubble Space Telescope results that suggest most large elliptical galaxies have shallow density cusps. This shallow cusp yields an almost constant surface density. The radius of this shallow cusp (core) roughly doubles at each merger event. This expansion of the core is supported by the energy production from the black hole binary. As a result, the ratio between the core radius and the half-mass radius remains roughly constant. This result is, again, in good agreement with the observed positive correlation between the core radius and effective radius of elliptical galaxies. In previous simulations of galactic mergers, the role of the central black holes was neglected. In these simulations, the half-mass radius increased but the core radius did not, in clear disagreement with observations. Our results imply that the existence of central black holes naturally explains the structure and size of the cores of bright elliptical galaxies, though other explanations (e.g., anisotropy) are not ruled out.
