industry to establish multi-hop paths and optional redundant paths for
characterized flows with deterministic properties. In this context
deterministic implies that streams can be established which provide
guaranteed bandwidth and latency which can be established from a Layer
3 (IP) interface.
Up-Regulation of the <i>Nedd2</i> Gene Encoding an ICE/Ced-3-Like Cysteine Protease in the Gerbil Brain after Transient Global Ischemia (1997)

We assessed the expression of several genes encoding pro-apoptotic cysteine proteases similar to interleukin-1 beta converting enzyme (ICE) and nematode Ced-3 in association with delayed neuronal death (DND) after transient forebrain ischemia in Mongolian gerbil. The levels of the two species of Nedd2 mRNA concomitantly increased about two-fold in the whole forebrain at 3-6 h after 10-min ischemia and declined to the basal level by 24 h. In situ hybridization revealed that the Nedd2 gene was up-regulated in some neuronal populations in CA1 and CA3 regions of the hippocampus. In contrast, expression of ICE, CPP32/Yama/Apopain, and TX/ICErelll did not change within 48 h. These observations raise the possibility that up-regulation of Nedd2 in the vulnerable neurons may contribute to the proteolytic processes preceding the manifestation of apoptosis and/or necrosis after ischemic insult.
Cyclodepolymerisation of bisphenol A polysulfone: evidence for self-complementarity in macrocyclic poly(ether sulfones) (1998)

The engineering thermoplastic generally referred to as ‘bisphenol A polysulfone’ undergoes fluoride-promoted cyclodepolymerisation; high molar mass polymer is thus transformed into a series of macrocyclic oligomers containing up to at least 72 aromatic rings; those containing up to 24 rings have been isolated as pure compounds, and single-crystal X-ray studies of the cyclotrimer and cyclotetramer reveal shape-complementary pairs and chains of macrocyles, respectively.
Tenso-resistive printed sensors for flexible elements of systems and mechanisms (2019)

The testing results of developed tenso-resistive (strain-gauge) sensors printed on 2 types of synthetic nonwovens, using 2 modified types of conductive inks based on carbon nanotubes, graphite, for such flexible high-load and stretchable elements as air-inflated structures, amortization groups and especially soft robotics systems and mechanism are presented. The strong correlation "stretch deformation range – electrical resistance – tenso-sensitivity" for each tested nonwovens was found. The sensors developed on synthetic nonwovens with nanotubes were defined to be most suitable for wider deformation control variety (0-80%) as well as humidity control with dividing on 3 narrow sensitive ranges from 0 to 10, 10-30 and 30-80% elongation. The affect of material density as well as prepress surface thermo-modification and environment conditions deviations was checked. The advantages of these sensors are low-cost and simple operation principle in contrast to other commercially available sensors or known prototypes. All of these sensors were produced using a screen-printing technique.

<title>Fast motion vector estimation with a Markov model for MPEG</title> (1995)

This paper presents a new approach for motion vector estimation. We first propose a stochastic model to describe the temporal correlation of motion vectors. We show that the optimal motion vectors can be obtained through maximum a posteriori sequence estimation method. This method is however not practically implementable due to its high computational complexity and many unknown modeling parameters. However, motivated by this theoretical framework, we propose a modified algorithm which is simple, accurate, and fast. First a set of good motion vector candidates is determined. By examining the distribution of these motion vector candidates, we can estimate the noise level as well as select the best motion vector by using the temporal correlations. Then, the next search window can be predicted by examining the trend of the motion vector variation and the noise level (a higher noise level leading to a large search window). In this way, we can reduce the search operation up to less than 0.5% compared to full block search. The excellent performance of the proposed algorithm is demonstrated through extensive experiments.
Serotonin increases the functional activity of capsaicin-sensitive rat trigeminal nociceptors via peripheral serotonin receptors (2011)

Peripheral serotonin (5HT) has been implicated in migraine and temporomandibular pain disorders in humans and animal models and yet the mechanism(s) by which 5HT evokes pain remains unclear. Trigeminal pain can be triggered by activation of the transient receptor potential V1 channel (TRPV1), expressed by a subset of nociceptive trigeminal ganglia (TG) neurons and gated by capsaicin, noxious heat, and other noxious stimuli. As 5HT is released in the periphery during inflammation and evokes thermal hyperalgesia, and TRPV1 is essential for thermal hyperalgesia, we hypothesized that 5HT increases the activity of capsaicin-sensitive trigeminal neurons and that this increase can be attenuated by pharmacologically targeting peripheral 5HT receptors. TG cultures were pretreated with 5HT (10 nM-100 μM), sumatriptan (5HT(1B/1D) agonist), ketanserin (5HT(2A) antagonist), granisetron (5HT(3) antagonist), or vehicle prior to capsaicin (30-50 nM). Single-cell accumulation of intracellular calcium was recorded or calcitonin gene-related peptide (CGRP) release was measured following each treatment. In addition, using in situ hybridization and immunohistochemistry, we detected the colocalization of 5HT(1B), 5HT(1D), 5HT(2A), and 5HT(3A), but not 5HT(2C) mRNA with TRPV1 in TG cells. 5HT pretreatment evoked a significant increase in calcium accumulation in capsaicin-sensitive trigeminal neurons and enhanced capsaicin-evoked CGRP release, but had no significant effect when given alone. Sumatriptan, ketanserin, and granisetron treatment attenuated calcium accumulation and 5HT enhancement of capsaicin-evoked CGRP release. Together these results indicate that 5HT increases the activity of capsaicin-sensitive peripheral nociceptors, which can be attenuated by pharmacologically targeting peripheral 5HT receptors, thereby providing a mechanistic basis for peripheral craniofacial pain therapy.
A Simple Organic Molecule Realizing Simultaneous TADF, RTP, AIE, and Mechanoluminescence: Understanding the Mechanism Behind the Multifunctional Emitter (2019)

Aggregation-induced emission (AIE), thermally activated delayed fluorescence (TADF), room-temperature phosphorescence (RTP), and mechanoluminescence (ML) have attracted widespread interest. However, a multifunctional organic emitter exhibiting simultaneous AIE, TADF, RTP, and ML has not been reported. Now, two multifunctional blue emitters with very simple structures, mono-DMACDPS and Me-DMACDPS, exhibit typical AIE, TADF, and RTP properties but different behavior in mechanoluminescence. Crystal structure analysis reveals that large dipole moment and multiple intermolecular interactions with tight packing mode endow mono-DMACDPS with strong ML. Combined with the data of crystal analysis and theoretical calculation, the separated monomer and dimer in the crystal lead to the typical TADF and RTP properties, respectively. Simple-structure mono-DMACDPS is the first example realizing TADF, RTP, AIE, and ML simultaneously.
No End Without the Means: John Wesley and the Sacraments (1991)

The teachings of John Wesley on the sacraments, their presuppositions, their content and consequences, are so extensive that large studies and several books would be necessary for a truly exhaustive presentation of his thought in this area.Consequently, this essay will merely survey the topic, lifting up some of the main points. 1 It is hoped that, in spite of these limitations, it will reveal some of Wesley's rich theology and whet the appetite for further Wesley studies.Wesley has often been accused of being inconsistent, fragmentary and even confused in his theological thinking.But a thorough study of his works reveals a different picture.His theology, and thus also his sacramental theology, is unitive and systematic and not incidental and disconnected.He has one unified doctrine of the sacraments, comprising baptism and the Lord's Supper, which forms an integral part of the greater unitive structure of his understanding of the ordo salutis.The theological and practical importance of the sacraments for John Wesley lies in their functions.Within the framework of the ordo salutis they function as (1) effective signs, (2) effective means of grace and (3) effective pledges of glory to come, conjoined with the added aspect of sacrifice. 2esley operates with a threefold doctrine of sin: first, original sin, involving guilt and loss of the image of God; second, involuntary sin, sins of infirmity, ignorance and error; third, actual willful sin against a known law (including the "law of love"), which in essence is a rebellion against God.Ole E.

X-force: force-executing binary programs for security applications (2014)

This paper introduces X-Force, a novel binary analysis engine. Given a potentially malicious binary executable, X-Force can force the binary to execute requiring no inputs or proper environment. It also explores different execution paths inside the binary by systematically forcing the branch outcomes of a very small set of conditional control transfer instructions. X-Force features a crash-free execution model that can detect and recover from exceptions. In particular, it can fix invalid memory accesses by allocating memory on-demand and setting the offending pointers to the allocated memory. We have applied X-Force to three security applications. The first is to construct control flow graphs and call graphs for stripped binaries. The second is to expose hidden behaviors of malware, including packed and obfuscated APT malware. X-Force is able to reveal hidden malicious behaviors that had been missed by manual inspection. In the third application, X-Force substantially improves analysis coverage in dynamic type reconstruction for stripped binaries.
Treatment of Obesity With “Combination” Pharmacotherapy (2010)

The increasing prevalence of obesity in the United States is widely recognized as a complex problem with significant public health implications, morbidity, mortality, and costs. Pharmacotherapy can contribute to the treatment of obesity. The regulation of appetite and body weight involves multiple parallel neuronal and bodily mechanisms. Not surprisingly, experience has shown that a medication that targets any one mechanism produces weight loss of 5%-10%. Although weight loss of this magnitude may produce significant reductions in risk factors associated with cardiovascular morbidity and mortality, patients expect cosmetically meaningful reductions in weight (~20%-25%). Combining 2 medications that work via different mechanisms, that is, "combination pharmacotherapy," is an approach to obtaining cosmetically relevant reductions in weight. The most effective example of this approach was the combination of phentermine and fenfluramine. This article will describe a novel combination pharmacotherapy developed in clinical practice: the combination of phentermine with the serotonin precursor L-5-hydroxytryptophan plus the peripheral decarboxylase inhibitor, carbidopa. Observational data on the efficacy and safety of this combination pharmacotherapy will be presented. In conclusion, combination pharmacotherapy can make important contributions to the treatment of obesity. Controlled clinical trials should be done before such combination treatments are widely adopted.
Large area real-time system for screening DNA libraries (1992)

A nuclear imaging system based on a position-sensitive photomultiplier tube (PSPMT) and scintillating fiber optics is described. A real-time, large-area imaging system has been constructed and tested using realistic phantoms and biological samples. This prototype, which has an active area of 112 cm/sup 2/ was found to be more than 100 times more sensitive for detection of /sup 32/P radiation than film and provided a spatial resolution of approximately 1.7 mm. By choosing suitable fiber dimensions and packing methods on the PSPMT this system is capable of producing images over an area equal to X-ray film and with spatial resolution approaching 0.5 mm. The digital nature of the image allows a great deal of freedom in processing and displaying data, including automatic identification and location of the desired features.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Closely related glycosylation patterns of recombinant human IL-2 expressed in a CHO cell line and natural IL-2. (1990)

We report here the study of the glycosylation pattern of human recombinant (r) IL2 expressed in a Chinese hamster ovary (CHO) cell line. The human rIL2 secreted by this high-producing recombinant CHO cell line was metabolically radiolabelled with [35S]-methionine, or with [3H]-glucosamine and [3H]-galactose, purified to homogeneity, and then characterized. The electrophoretic analysis of the [35S]-methionine-labelled proteins present in the culture medium of the CHO cell line showed that the rIL2 represents approximately 12% of the total secreted proteins. Furthermore, pulse-chase experiments showed that the glycosylated rIL2 is synthesized and secreted within 30 min. The point of attachment and the structure of the carbohydrate moiety of the rIL2 was determined by: amino-terminal sequencing and fingerprint analysis of the 3H-labelled rIL2, mass spectroscopy of the amino-terminal tryptic octapeptide, and carbohydrate analysis after enzymatic (Vibrio cholerae neuraminidase and Aspergillus oryzae beta-galactosidase) or sulfuric acid hydrolysis. The results indicate that the recombinant protein possesses a sugar moiety O-linked to the threonine residue at position 3 of the polypeptide chain, and that sialic acid, galactose and N-acetyl galactosamine are components of this carbohydrate moiety. Taken together these results suggest that the recombinant molecule is identical to natural IL2.
An Opsin Mutant with Increased Thermal Stability (2003)

This report describes the biochemical characterization of a double mutant of rhodopsin (N2C,D282C) in which Cys residues engineered into the protein at positions 2 (in the amino-terminal extracellular domain) and 282 (in the extracellular loop between transmembrane helices 6 and 7) are shown to form a disulfide bond and increase the thermal stability of the unliganded or opsin form of the protein. Wild-type opsin does not survive detergent solubilization and purification at pH 7.5 and 25 degrees C. In contrast, the N2C,D282C mutant opsin survives the purification protocol and loses less than 50% activity after incubation for 20 days under the same conditions. Less than 5% is lost after 20 days at 4 degrees C. While the disulfide bond clearly has a dramatic effect on protein stability, it has a minor impact on the activity of the pigment. The MII lifetime of the mutant (6.6 min) is similar to that of the wild type (7.9 min), and the specific activity of the light-activated mutant for activation of transducin is within 20% of the wild-type activity. Therefore, it seems likely that the disulfide bond does not perturb greatly the structure of the protein. For these reasons, we anticipate that the mutant may be of use in detailed kinetic and mechanistic investigations of the ligand binding reaction and for crystallization trials involving recombinant rhodopsin, especially the unliganded opsin form of the protein.
Wavelets in computer graphics (1996)

One of the perennial goals in computer graphics (CC) is realism in real time. Handling geometrically complex scenes and physically faithful descriptions of their appearance and behavior clashes with the requirement of multiple frame per second update rates. It is no surprise then that hierarchical modeling and simulation have already enjoyed a long history in CG. Most recently these ideas have received a significant boost as wavelet based algorithms have entered many areas in CG. We give an overview of some of the areas in which wavelets have already had an impact on the state of the art.
Integrated approach for circuit and fault extraction of VLSI circuits (2002)

The purpose of this paper is to present a methodology for circuit and realistic fault extraction, and its implementation in a new tool, under development. To be included in a virtual test environment, DOTLab. Digital, analog and mixed signal ICs, implemented in CMOS, bipolar or BiCMOS technologies are handled, both in Manhattan and 45/spl deg/ geometries. For complex circuits, higher level information, obtained in the top-down design flow, is used for fault characterization. A sliding window algorithm previously used for circuit extraction, is extended for fault extraction of non-orthogonal geometries.

High-performance cell transistor design using metallic shield embedded shallow trench isolation (MSE-STI) for Gbit generation DRAM's (1999)

In this paper, the cell transistor design issues for the Gbit level DRAM's with the isolation pitch of less than 0.2 /spl mu/m caused by the inverse-narrow-channel effect (INCE) and the neighboring storage-node E-field penetration effect (NSPE) will be discussed. Then we propose novel DRAM cell transistor structure by employing metallic shield inside the shallow trench isolation (STI). As confirmed by three-dimensional (3-D) device simulation results, by suppressing the inverse narrow-channel effect and the neighboring storage-node E-field penetration effect using metallic shield inside STI, we can obtain reliable cell transistors with low-doped substrate, low junction leakage current and uniform V/sub TH/ a distribution regardless of the active width variation.
Brine and Permeability Effects on Crosslinked Fluid-Loss Pill Filter-Cake Formation (2005)

Abstract During completion and workover for the recovery of oil and gas, fluid loss pills are used to control completion brine losses to the formation. Basically, the operator has three types of fluid loss pills to choose. They are linear water soluble polymers like hydroxy ethylcellose (HEC), solids laden, and the most recent crosslinked pills. Since both HEC and crosslinked pills are considered solids free, crosslinked pills are more effective on higher permeability formations by the formation of a polymer filter cake. However, little work has been done to define the permeability limit for these crosslinked pills and when an operator should use a solids laden pill instead of a crosslinked one. Also, the brine type effects the overall efficacy of the fluid loss pill. Therefore, lab tests were conducted to address these issues by evaluating a crosslinked zirconium carboxy methyl hydroxy ethyl cellulose (CMHEC) pill. The tests showed that as the calcium halide increases the ability for filter cake formation for this crosslink pill decreases with permeability. For example, for crosslinked CMHEC in water at 180°F, the limit is less than 20 Darcy (60 micron) but in a 14.2 ppg calcium bromide solution; the limit is less than 2 Darcy (10 micron). Other variables like pH and temperature are discussed to provide guidelines.
Analysis of electrically large patch phased arrays via CFDTD (2006)

To validate the CFDTD code, analysis was first carried out on a smaller array with 64 elements. The structure was built up with elements identical to those used in the 10,000-element array. Models of the validation array were constructed using both CFDTD and XFDTD. The array radiation patterns were shown for 0/spl deg/, 30/spl deg/, 45/spl deg/, and 60/spl deg/ scan angles at the center frequency of 1.75 GHz. The beam was scanned in the /spl Phi/ = 90/spl deg/ plane. The solid lines represent CFDTD data while the dotted lines indicate the corresponding XFDTD set. As the beam is steered away from boresight, the 3-dB beamwidth increases from 12.9/spl deg/ at boresight to 26.2/spl deg/ at the 60/spl deg/ scan angle. The first sidelobe level is about 13 dB below the peak when the main beam is pointed at boresight. The total change in peak sidelobe level is 4.0 dB as the beam is scanned from boresight to 60/spl deg/. The array directivity calculated with CFDTD is 23.0 dB, which is within 0.2 dB of the value given by XFDTD. Furthermore, the scan loss from 0/spl deg/ to 60/spl deg/ is observed to be 3.0 dB with CFDTD and 2.8 dB with XFDTD. These values are consistent with expectations for a well behaved array with 0.5/spl lambda/ element spacing.
Gas Turbine Compressor Washing: Historical Developments, Trends and Main Design Parameters for Online Systems (2005)

By being exposed to atmospheric conditions gas turbines are inevitably subjected to sources of fouling. The resulting degradation can be partially recovered by cleaning the compressor. Based on open literature and patents, the different approaches leading to the most advanced method of compressor online washing have been compiled. The origins of online washing and the development trends over the decades are outlined, and the current systems are categorized. The introduction of system categories has been justified by a field survey. Additionally, the main design parameters of online washing systems are summarized.
