Universal constructions for large objects (1999)

We present lock-free and wait-free universal constructions for implementing large shared objects. Most previous universal constructions require processes to copy the entire object state, which is impractical for large objects. Previous attempts to address this problem require programmers to explicitly fragment large objects into smaller, more manageable pieces, paying particular attention to how such pieces are copied. In contrast, our constructions are designed to largely shield programmers from this fragmentation. Furthermore, for many objects, our constructions result in lower copying overhead than previous ones. Fragmentation is achieved in our constructions through the use of load-linked, store-conditional, and validate operations on a "large" multiword shared variable. Before presenting our constructions, we show how these operations can be efficiently implemented from similar one-word primitives.
Crystallinity and morphology of segmented polyurethanes with different soft-segment length (1996)

A series of polycaprolactone/4,4′-diphenylmethane diisocyanate/1,4-butanediol (PCL/MDI/BDO) segmented polyurethanes of different compositions was synthesized by solution polymerization. The molecular weight of PCL diols used was in the range of 1600–7000. The crystallinity and morphology of these polymers were studied by using DSC, dynamic mechanical analysis, WAXD, and polarizing microscopy methods. It was found that the crystallinity of PCL prepolymers was depressed in segmented polyurethanes. A lower limit of PCL molecular weight was found, below which the PCL segments were not able to crystallize at the usual processing conditions. This limit of molecular weight is in the range of 2000–3000 and exhibits a slight increase with increasing hard-segment content of polyurethanes. The glass transition temperature related to the PCL segment regions in polyurethane specimens deviated from that of pure amorphous PCL prepolymer to a higher temperature. The deviation resulted from the crystallization of PCL segments and also the influence of hard segments. The formation of hard-segment domains becomes very difficult for polyurethanes having low hard-segment content and short hard-segment length. There is a lower limit of hard-segment content and segment length. Only above that limit do the polyurethanes have enough hard-segment domains acting as physical crosslinks at temperatures above the melting point of the PCL crystals. The structural characteristics of segmented polyurethanes which may exhibit a shape memory effect are also discussed. © 1996 John Wiley & Sons, Inc.

Electric-field penetration into metals: consequences for high-dielectric-constant capacitors (1999)

A consequence of the finite electronic screening length in metals is that electric fields penetrate short distances into the metal surface. Using a simple, semiclassical model of an idealized capacitor, we estimate the capacitance correction due to the distribution of displacement charge in the metal electrodes. We compare our result with experimental data from thin-film high-dielectric-constant capacitors, which are currently leading contenders for use in future high-density memory applications. This intrinsic mechanism contributes to the universally-seen decrease in measured dielectric constant with capacitor film thickness.

The Impact of Rosenberger v. Rector and Visitors of University of Virginia on Public Forum Doctrine (1999)

Abstract In Rosenberger the Supreme Court held that the denial of funds for a student religious publication at the University of Virginia was unconstitutional viewpoint discrimination. The decision signaled a change in public forum doctrine in cases involving religious speech. This paper examines how lower federal courts have applied the Rosenberger decision in public forum cases. Most of the cases have involved situations that move well beyond the issue of funding student groups at public universities. Lower courts have been divided in their treatment of the decision. In ten cases the Rosenberger precedent was followed as controlling authority but in eleven others it was used by dissenting judges. In the remaining cases, the precedent was either distinguished or it did not play a central role in the opinion. Despite the variance in lower court application, the Rosenberger decision has had an impact on public forum doctrine, especially where religious speech is concerned.

BiDirectional optical communication with AquaOptical II (2010)

This paper describes AquaOptical II, a bidirectional, high data-rate, long-range, underwater optical communication system. The system uses the software radio principle. Each AquaOptical II modem can be programmed to transmit user defined waveforms and record the received waveforms for detailed analysis. This allows for the use of many different modulation schemes. We describe the hardware and software architecture we developed for these goals. We demonstrate bidirectional communication between two AquaOptical II modems in a pool experiment. During the experiment AquaOptical II achieved a signal to noise ration of 5.1 over a transmission distance of 50 m at pulse widths of 1 μsec, 500 ns, and 250 ns. When using discrete pulse interval modulation (DPIM) this corresponds to a bit-rate of 0.57 Mbit/s, 1.14 Mbit/s, and 2.28 Mbit/s.
Tricyclic psychotropic agents containing two chalcogen atoms in the central ring: 8-Substituted 6-(4-piperidyl)-6H-dibenz[b,e]-1,4-oxathiepins (1982)

2-(2-Fluorophenylthio)benzaldehydes IXa-c and 5-chloro-2-(2-fluorophenylthio)acetophenone were treated with 1-methyl-4-piperidylmagnesium chloride and 3-dimethylaminopropylmagnesium chloride, respectively, and the resulting amino alcohols VIa-c, XVII and XVIII were cyclized with sodium hydride in dimethylformamide. In addition to the title compounds Ia-c, XIX and XX , several types of by-products were obtained. Demethylation of compound Ib by the chloroformate method afforded the secondary amine IIb which was transformed to the amino alcohols IIIb and Vb . Compounds Ia-c are very potent neuroleptics with a high degree of central depressant and cataleptic activity. The amino alcohol Vb exhibits a very strong antiapomorphine effect in rats.
Cholecystokinin expression in the developing and regenerating pancreas and intestine (2001)

In developmental terms, the endocrine system of neither the gut nor the pancreatic islets has been characterized fully. Little is known about the involvement of cholecystokinin (CCK), a gut hormone, involved in regulating the secretion of pancreatic hormones, and pancreatic growth. Here, we tracked CCK-expressing cells in the intestines and pancreata of normal mice (BALB/c), Non Obese Diabetic (NOD) mice and interferon (IFN)-gamma transgenic mice, which exhibit pancreatic regeneration, during embryonic development, the postnatal period and adulthood. We also questioned whether IFN-gamma influences the expression of CCK. The results from embryonic day 16 showed that all three strains had CCK in the acinar region of pancreata, and specifically in alpha cells that also expressed glucagon. However, in adulthood only BALB/c and NOD mice continued this pattern. By contrast, in IFN-gamma transgenic mice, CCK expression was suppressed from birth to 3 months of age in the pancreata but not intestines. However, by 5 months of age, CCK expression appeared in the regenerating pancreatic ductal region of IFN-gamma transgenic mice. In the intestine, CCK expression persisted from fetus to adulthood and was not influenced by IFN-gamma. Intestinal cells expressing CCK did not co-express glucagon, suggesting that these cells are phenotypically distinct from CCK-expressing cells in the pancreatic islets, and the effect of IFN-gamma on CCK varies depending upon the cytokine's specific microenvironment.

Fast Power Semiconductors Switching Current Measurement by Current Surface Probe (2015)

With the advantage of high bandwidth and small insertion impedance, a current surface probe (CSP) used to measure switching current waveforms is presented in this paper. Its transfer impedance is characterized and validated by measuring an IGBT switching current that is compared with those obtained with a current probe (CP), a current shunt (CS) and a Hall effect current probe (HECP). Furthermore, by comparing with a CS to measure a GaN-HEMT switching current, it is shown that CSP is able to measure a switching current of a few nanoseconds, while it brings no influence on transistor voltage waveform measurement. The obtained results show that, the use of CSP brings little parasitic inductances in the measurement circuit and it does not bring the connection of the ground to the power converter, which is the case for the CS.
In vivoevaluation of a neural stem cell-seeded prosthesis (2009)

Neural prosthetics capable of recording or stimulating neuronal activity may restore function for patients with motor and sensory deficits resulting from injury or degenerative disease. However, overcoming inconsistent recording quality and stability in chronic applications remains a significant challenge. A likely reason for this is the reactive tissue response to the devices following implantation into the brain, which is characterized by neuronal loss and glial encapsulation. We have developed a neural stem cell-seeded probe to facilitate integration of a synthetic prosthesis with the surrounding brain tissue. We fabricated parylene devices that include an open well seeded with neural stem cells encapsulated in an alginate hydrogel scaffold. Quantitative and qualitative data describing the distribution of neuronal, glial, and progenitor cells surrounding seeded and control devices are reported over four time points spanning 3 months. Neuronal loss and glial encapsulation associated with cell-seeded probes were mitigated during the initial week of implantation and exacerbated by 6 weeks post-insertion compared to control conditions. We hypothesize that graft cells secrete neuroprotective and neurotrophic factors that effect the desired healing response early in the study, with subsequent cell death and scaffold degradation accounting for a reversal of these results later. Applications of this biohybrid technology include future long-term neural recording and sensing studies.
Models for dependability and sustainability analysis of data center cooling architectures (2012)

The advent of cloud computing, social networks and e-commerce have demanded more computational resources from data centers. Prominent issues are sustainability, cost and dependability, which are significantly impacted by the redundant infrastructures needed to support those services. In this context, models are important to support data center designers to estimate previous issues before implementing the final architecture. This paper proposes a set of models for the integrated quantification of sustainability impact, cost and dependability of data center cooling infrastructures with the support of an environment, namely, ASTRO. Besides, a model is proposed for verifying if the energy flow does not exceed the maximum energy capacity that each component can provide (considering power devices) or the maximum cooling capacity (assuming cooling equipment). Additionally, this work presents a case study which analyzes the environmental impact, dependability metrics as well as the acquisition and operational costs of five real-world data center cooling architectures.
Fragmentation of diketopiperazines from Aspergillus fumigatus by electrospray ionization tandem mass spectrometry (ESI‐MS/MS) (2007)

Diketopiperazines (DKPs) corresponding to cyclic dipeptides have been reported to exhibit antimicrobial, antitumor, antimutagenic and antiviral properties. These compounds are commonly isolated from microorganisms and sponges and from a variety of tissues and body fluids. In this work, we used electrospray ionization tandem mass spectrometry (ESI-MS/MS) to investigate the fragmentation of a series of DKPs previously isolated from Aspergillus fumigatus, which exhibit the same structural core. Loss of CO directly from the protonated molecule was found to be a fragmentation process common to all the compounds analyzed. However, our results revealed a series of ions that are diagnostic for the substituents at C(4) and C(9). In order to rationalize the differences in the fragmentation pathways of substituted and nonsubstituted DKPs, the relative Gibbs energies (DeltaG) of the product ions and intermediate ions were estimated using the B3LYP/6-31 + + G(d,p) model. The data reported here can be used for the structural elucidation of DKPs from low sample amounts, as an alternative to NMR.

Basic study of incremental forming of serially arranged hybrid parts using cross-wedge rolling (2017)

The superior aim of the Collaborative Research Centre 1153 "Tailored Forming" is to develop potentials for hybrid solid components made of two different materials on the basis of a new process chain using joined semi-finished workpieces. For the subproject B1 the objective is to determine the formability of novel hybrid parts using the incrementally reshaping process cross-wedge rolling. Due to the different materials, the hybrid semi-finished parts have different flow resistances and therefore an unequal forming behaviour at the same workpiece temperature. In this paper, investigations about the displacement of the joining zone of serially arranged (frontally joined cylinders) semi-finished hybrid parts are presented. The investigated material combinations are steel-steel (C22 and 41Cr4) and steel-aluminium (20MnCr5 and AlSi1MgMn). The rolling process is designed using FEM simulation and the cross-wedge rolling process was experimentally investigated afterwards. Research priorities are investigations of the displacement of the joining zone depending on the main parameters of cross wedge rolling. It could be shown that the forming behaviour of serially arranged hybrid parts made of steel-steel and steel-aluminium can be described using FEM. The deviation of the simulated displacement of the joining zone compared to the trials is only about 3 %, which is a good approximation.
USE OF PROGESTERONE-BASED FTAI PROTOCOL FOLLOWED BY GnRH OR hCG TREATMENT ON DAY 6 POST-AI IN REPEAT BREEDER CATTLE (2017)

Repeat breeder cattle (n=45) were synchronized using intravaginal progestational device (TRIU-B) based Co-Synch protocol. On day 6 post artificial insemination (AI), all the animals were administered (i.m.) either 10 μg GnRH analogue, (n=15), 1500 IU hCG (n=15) or normal saline (n=15). Pregnancy diagnosis was carried out on day 45 post-AI. Jugular vein blood was collected on day 6 and day 12 post-AI for serum progesterone estimations. On day 12 post-AI, serum progesterone values both overall as well as in the conceived animals were high (p<0.05) in hCG group compared to control. In GnRH, hCG and control group, the respective conception rate was 40%, 46.7% and 33.3%. In brief, administration of hCG on day 6 post AI improves subsequent luteal profile with tendency for better conception rate in repeat breeder cattle.
Rate controlling for color and depth based 3D video coding (2008)

Rate control is a very important tool for any kind of video coding and transmission. Even though there are many rate control techniques designed for 2D video, not much work has been carried out in this area for 3D video. In this paper, a novel rate control approach for 3D video based on color and depth maps is introduced. The aim of this rate control algorithm is to keep the 3D video quality near constant. Since the 3D video is synthesized from color and depth maps and the final quality of 3D video is more influenced by color sequence rather than depth maps, the qualities of both color and depth maps are firstly varied until the target 3D quality is achieved with minimal bit rate. Subsequently, the PSNR of both color and depth maps at the optimum point are maintained for the entire group of picture (GOP). The bit-allocation problem is solved by introducing a Lagrangian optimization cost function. According to experimental results, the proposed rate control technique is capable to adjust the bit rate allocated to the color and depth maps sequences adaptively in order to maximize 3D video quality which is measured by PSNR of the synthesized left and right views using reconstructed color and depth map sequences.
Synthèse d'analogues de tétraponérines, alcaloïdes défensifs des fourmis du genre Tetraponera (2003)

Les fourmis du genre Tetraponera appartiennent à la sous-famille des Pseudomyrmecinae et sont exceptionnelles par leur comportement défensif particulier. En effet, en cas d’attaque, ces fourmis disposent leur abdomen latéralement et badigeonnent la cuticule de l’adversaire au moyen de leur aiguillon en forme de tire-ligne. L’injection en chromatographie gazeuse capillaire de cette sécrétion a montrés qu’elle était constituée de huit dérivés, les tétraponérine T-1 à T-8. Ces molécules se rattachent à des squelettes tricycliques originaux et possèdent des propriétés neurotoxiques et insecticides. Dans le cadre d’une étude structure-activité de ces alcaloïdes, nous nous sommes intéressés à la synthèse d’analogues basés sur un squelette decahydro-dipyrido[1,2-a : 1’,2’-c]pyrimidine. Les différentes conditions réactionnelles utilisées pour synthétiser ce squelette à partir de pipéridéine et de malonate de diéthyle, ainsi que la nature et la détermination de structure des produits obtenus dans chaque cas seront discutées.
