Strain-optic relations of cellulose acetate during creep deformation. (1988)

The fringe order obtained by the photoplastic test gives important information on the mechanical properties of transparent polymers. However, the effect of viscosity on the fringe order has not been investigated sufficiently. In this paper, the time-dependent photomechanical properties of cellulose acetate was examined by means of the creep test under uniaxial tension. As a result, the creep behavior of cellulose acetate is considerably influenced by both stress and temperature. Moreover, the creep strain and the creep fringe order are described simply by the power-law of time, respectively, and constants of these equations are determined only by the ratio of stress to the yield stress at several temperatures. Finally, the relation between strain and fringe order during creep deformation is equivalent to that under uniaxial tensile loading, which does not depend both on stress and on creep time.
An Actionable Threat Intelligence system using a Publish-Subscribe communications model (2015)

We designed a system for securely distributing Threat Intelligence and recommended Courses of Action (CoAs), combining that information with local contextual information, determining which response system(s) can carry it out, and then putting the course of action into effect. Our system uses STIX to express threat information, including CoAs. We identified the problem of matching CoAs with the actions that a response system can carry out as a major design challenge, and found a robust and scalable decentralized solution to that challenge by adopting a publish-subscribe model. We built a solution based on the Extensible Messaging and Presence Protocol (XMPP) architecture and communications protocol as it provided the right security properties as well as the needed extensibility for both data model and transport protocols. We motivate and describe our system, and the use cases of Cyber Threat Prevention, Cyber Threat Detection, and Incident Response.

Renin inhibitors. Free-Wilson and correlation analysis of the inhibitory potency of a series of pepstatin analogs on plasma renin (1987)

Free-Wilson and correlation analysis were combined to study a series of 34 pepstatin analogues in which mainly position 2 was varied. A statistically highly significant correlation was found between the inhibitory activity of the analogues on an enriched plasma renin preparation and structural parameters of the amino acid side chain in position 2. The crucial parameters were found to be the NMR chemical shift of the alpha-carbon, the localized electrical (inductive) effect, and the van der Waals radius related steric parameter, which demonstrated the dominating influence of electronic inductive effects compared to steric bulk. The model gives insight into the structural requirements for effective inhibition and suggests the histidine-2 derivative, a positive outlier in this series, as a lead compound for further structure-activity studies.
<title>Status of the GAF Tornado reconnaissance system</title> (1996)

The development of the new reconnaissance pod for the German Air Force is continuing according to schedule. A first flight is planned for the end of 1996. Carried on the centerline station of the IDS Tornado, the pod contains two daylight film cameras and one infra-red linescanner system. The infra-red image is recorded on a digital tape recorder and will also be displayed on the TV-Tabs. The modular structure of the pod exhibits a high flexibility for incorporation of various sensor systems on other payloads.
Photopolymerization of Polyfunctional Acrylates and Methacrylate Mixtures:  Characterization of Polymeric Networks by a Combination of Fluorescence Spectroscopy and Solid State Nuclear Magnetic Resonance (1997)

Fluorescence spectroscopy and solid state NMR methods were used to elucidate the detailed molecular structure of poly(meth)acrylate networks. Both techniques can be employed on identical samples and give complementary information. In this study a series of diacrylates, a series of dimethacrylates, and 1:1 mixtures of the triacrylate TMPTA with diacrylates (DA's) or dimethacrylates (DMA's), respectively, was investigated. Fluorescence spectroscopy was performed, using the shift in the fluorescence maximum of 4-(dimethylamino)-4‘-nitrostilbene (1), a charge transfer probe. This probe monitors both the rigidity and the polarity of the medium in which it is incorporated. CPMAS 13C NMR spectroscopy was employed monitoring the relaxation times, T1, of carbon atoms from the main chains and pendant groups, determining cross-link densities, and measuring T1ρ(1H) values. With these techniques information about the mobility of individual atoms and the homogeneity of the polymeric networks is obtained.

Peripheral tolerance induction by PD-L1+ lymphatic endothelial cell is due to deficient costimulation that leads to rapid, high-level expression of PD-1 on CD8 T cells (176.24) (2012)

Abstract It has been shown that lymph node (LN) stromal cells directly present peripheral tissue antigens (PTA) leading to systemic peripheral tolerance. In particular, lymphatic endothelial cells (LEC) directly present an epitope from tyrosinase to CD8 T cells (TCD8). Here, we determined the roles of costimulatory and inhibitory pathways in the induction of LEC-mediated tolerance. LEC do not express costimulatory ligands but do express ligands for the PD-1, CD80, CD160, BTLA, and LAG-3 inhibitory pathways. Nonetheless, LEC-mediated deletion of tyrosinase-specific TCD8 is solely dependent on the PD-1:PD-L1 pathway. Based on radioresistance and the fact that LEC express the highest levels of any LN resident cell, we conclude that PD-L1 expressed by LEC is necessary and sufficient for tyrosinase-specific TCD8 deletion. Presentation of tyrosinase by LEC leads to deletion by inducing more rapid, high-level PD-1 expression on TCD8 than that induced by professional APC. This is due to lack of costimulation by LEC, and is correctable with agonistic anti-4-1BB and OX-40. Apoptosis of tyrosinase-specific TCD8 induced by PD-1 is a consequence of failure to upregulate the IL-2 receptor. Rescue of tyrosinase-specific TCD8 from LEC-mediated deletion by interference with PD-1:PD-L1 or provision of costimulatory signals leads to the induction of autoimmune vitiligo. As LEC express numerous PTA, this mechanism may be of general importance in the development of autoimmune diseases.
Post Sample Adaptive Offset for Video Coding (2019)

In-loop filtering is an important task in video coding, as it refines both the reconstructed signal for display and the pictures used for inter-prediction. At the current stage of the Versatile Video Coding (VVC) standardization, there are three in-loop filtering procedures consisting of deblocking filter (DBF), sample adaptive offset (SAO) and adaptive loop filter (ALF). Among them, SAO is the simplest in-loop filtering process and highly effective in removing coding artifacts. It simply modifies decoded samples by conditionally adding an offset value to each sample after the application of the DBF. For this, a classification is applied for each sample location, which gives a partition of the set of all sample locations. After that, an offset value is added to all samples associated with each class. Therefore, the performance of SAO essentially relies on how its classification behaves. In this paper, we introduce a novel classification method for SAO. Based on this, we derive an additional SAO filtering process which we call post sample adaptive offset (PSAO). Experimental results show the effectiveness of our proposed PSAO filtering process. On average, 0.42%, 0.31% and 0.33% additional coding gains can be achieved on top of VTM-5.0 for all intra (AI), random access (RA) and low delay with B pictures (LB) configurations, respectively.

Three-phase Unidirectional Quasi-Single-Stage Delta-Switch Rectifier + DC-DC Buck Converter (2019)

This work presents a unidirectional three-phase PFC rectifier well-suited for application targeting high efficiency and/or high power density, such as DC-type electric vehicle chargers. Herein, a quasi-single stage AC-DC converter is proposed where a conventional three-phase DELTA-switch voltage source rectifier is cascaded to a PWM interleaved buck-type DC-DC converter by means of a low energy storage DC-link. The characteristics of the presented power electronics, including the principles of operation, modulation strategy, suitable PWM control scheme, and dimensioning equations are described in this paper. The presented circuit is benchmarked against other solutions for a 50 kW power capability battery charger. The results show a superior power efficiency of the proposed system.
A 130-nm 6-GHz 256 × 32 bit leakage-tolerant register file (2002)

Describes a 256-word /spl times/ 32-bit 4-read, 4-write ported register file for 6-GHz operation in 1.2-V 130-nm technology. The local bitline uses a pseudostatic technique for aggressive bitline active leakage reduction/tolerance to enable 16 bitcells/bitline, low-V/sub t/ usage, and 50% keeper downsizing. Gate-source underdrive of -V/sub cc/ on read-select transistors is established without additional supply/bias voltages or gate-oxide overstress. 8% faster read performance and 36% higher dc noise robustness is achieved compared to dual-V/sub t/ bitline scheme optimized for high performance. Device-level measurements in the 130-nm technology show 703/spl times/ bitline active leakage reduction, enabling continued V/sub t/ scaling and robust bitline scalability beyond 130-nm generation. Sustained performance and robustness benefit of the pseudostatic technique against conventional dynamic bitline with keeper-upsizing is also presented.
The Glut1 and Glut4 glucose transporters are differentially expressed during perinatal and postnatal erythropoiesis (2008)

Glucose is a major source of energy for living organisms, and its transport in vertebrates is a universally conserved property. Of all cell lineages, human erythrocytes express the highest level of the Glut1 glucose transporter with more than 200,000 molecules per cell. However, we recently reported that erythrocyte Glut1 expression is a specific trait of vitamin C-deficient mammalian species, comprising only higher primates, guinea pigs, and fruit bats. Here, we show that in all other tested mammalian species, Glut1 was transiently expressed in erythrocytes during the neonatal period. Glut1 was up-regulated during the erythroblast stage of erythroid differentiation and was present on the vast majority of murine red blood cells (RBCs) at birth. Notably though, Glut1 was not induced in adult mice undergoing anemia-induced erythropoiesis, and under these conditions, the up-regulation of a distinct transporter, Glut4, was responsible for an increased glucose transport. Sp3 and Sp1 transcriptions factors have been proposed to regulate Glut1 transcription, and we find that the concomitant repression of Glut1 and induction of Glut4 was associated with a significantly augmented Sp3/Sp1 ratio. Glucose transporter expression patterns in mice and human erythrocytes are therefore distinct. In mice, there is a postnatal switch from Glut1 to Glut4, with Glut4 further up-regulated under anemic conditions.

Pyranose oxidase: A versatile sugar oxidoreductase for bioelectrochemical applications (2019)

Pyranose oxidase (POx) is an FAD-dependent oxidoreductase, and like glucose oxidase (GOx) it is a member of the glucose-methanol-choline (GMC) superfamily of oxidoreductases. POx oxidizes several monosaccharides including D-glucose, D-galactose, and D-xylose, while concurrently oxygen is reduced to hydrogen peroxide. In addition to this oxidase activity, POx shows pronounced activity with alternative electron acceptors that include various quinones or (complexed) metal ions. Even though POx in general shows properties that are more favourable than those of GOx (e.g., a considerably higher catalytic efficiency (k<sub>cat</sub>/K<sub>m</sub>) for D-glucose, significantly lower Michaelis constants K<sub>m</sub> for D-glucose, reactivity with both anomeric forms of D-glucose) it is much less frequently used for both biosensor and biofuel cell applications than GOx. POx has been applied in biosensing of D-glucose, D-galactose, and D-xylose, and in combination with α-glucosidase also maltose. An attractive application is in biosensors constructed for the measurement of 1,5-anhydro-D-glucitol, a recognised biomarker in diabetes. Bioelectrochemical applications of POx had been restricted to enzymes of fungal origin. The recent discovery and characterisation of POx from bacterial sources, which show properties that are very distinct from the fungal enzymes, might open new possibilities for further applications in bioelectrochemistry.
P2P-IM: A P2P Presence System for the Internet (2007)

Traditional instant messaging applications rely on central server infrastructure to broker user information. The cost and complexity of this infrastructure makes it difficult for developers to build and deploy lightweight presence and instant messaging systems within their own applications. In this paper, we describe P2P-IM, a peer-to-peer instant messaging client that does not rely on any hosted server infrastructure. The system provides the rich facilities available from traditional client-server systems but enables easy deployment and integration with existing applications. The solution provides simplified identity generation, connectivity, and rich per-application data publication.

DAB2IP loss confers the resistance of prostate cancer to androgen deprivation therapy through activating STAT3 and inhibiting apoptosis (2015)

Loss of DAB2IP, a novel tumor suppressor gene, is associated with the high risk of aggressive prostate cancer (PCa). Previously, we reported that DAB2IP modulated androgen receptor activation in the development of castration-resistant PCa; however, its direct action on the failure of androgen deprivation therapy (ADT) remains largely unknown. In this study, we showed that DAB2IP knockdown could significantly enhance in vitro growth and colony formation of PCa cells following ADT as well as tumorigenicity in pre-castrated nude mice. In addition, DAB2IP loss stabilized mitochondrial transmembrane potential, prevented release of cytochrome c, Omi/HtrA2 and Smac from the mitochondria to the cytoplasm and inhibited intrinsic apoptosis induced by ADT. Mechanistically, DAB2IP could interact with the signal transducer and activator of transcription 3 (STAT3) via its unique PR domain and suppress STAT3 phosphorylation and transactivation, leading to the inhibition of survivin expression in PCa cells. Moreover, the luminal epithelia in DAB2IP(-/-) mice with more activated STAT3 and survivin expression were resistant to castration-induced apoptosis. Consistently, DAB2IP expression inversely correlated with STAT3 phosphorylation and survivin expression in PCa patients. Together, our data indicate that DAB2IP loss reprograms intracellular signal transduction and anti-apoptotic gene expression, which potentiates PCa cell survival from ADT-induced cell death.

Foaming of precursor of porous aluminum consisting of dissimilar aluminum alloys by frictional heating during friction stir processing (2022)

In our previous study, a precursor of porous aluminum consisting of uniform aluminum alloy was foamed by frictional heating during friction stir processing. It was found that the temperature at the tool gradually increased as the tool traversed owing to the heat stored in the steel plate. In this study, a precursor of porous aluminum welding a lower-foaming-temperature ADC12 (Al-Si-Cu) alloy precursor and a higher-foaming-temperature A6061 (Al-MgSi) alloy precursor was foamed during friction stir processing of a steel plate. It was shown that by placing ADC12 in the first-half region of tool traversal and A6061 in the latter half, the precursor can be sufficiently foamed, and porous aluminum consisting of ADC12 and A6061 can be obtained up to the tool traversal speed of 20 mm/min.
Water Utilization in Data Center Infrastructure (2010)

Fresh water is one of the few resources which is scarce and has no replacement; it is also closely coupled to energy consumption. Fresh water usage for power generation and other cooling applications is well known and accounts for 40% of total freshwater withdrawal in the U. S[1]. A significant amount of energy is embedded in the consumption of water for conveyance, treatment and distribution of water. Waste water treatment plants also consume a significant amount of energy. For example, water distribution systems and water treatment plants consume 1.3MWh and 0.5MWh[2], respectively, for every million gallons of water processed. Water consumption in data centers is often overlooked due to low cost impact compared to energy and other consumables. With the current trend towards local onsite generation[3], the role of water in data centers is more crucial than ever. Apart from actual water consumption, the impact of embedded energy in water is only beginning to be considered in water end-use analyses conducted by major utilities[4]. From a data center end-use perspective, water usage can be characterized as direct, for cooling tower operation, and indirect, for power generation to operate the IT equipment and cooling infrastructure[5]. In the past, authors have proposed and implemented metrics to evaluate direct and indirect water usage using an energy-based metric. These metrics allow assessment of water consumption at various power consumption levels in the IT infrastructure and enable comparison with other energy efficiency metrics within a data center or among several data centers[6]. Water consumption in data centers is a function of power demand, outside air temperature and water quality. While power demand affects both direct and indirect water consumption, water quality and outside air conditions affect direct water consumption. Water from data center infrastructure is directly discharged in various forms such as water vapor and effluent from cooling towers. Classification of direct water consumption is one of the first steps towards optimization of water usage. Subsequently, data center processes can be managed to reduce water intake and discharge. In this paper, we analyze water consumption from data center cooling towers and propose techniques to reuse and reduce water in the data center.
