Dynamic Properties Influence the Perception of Facial Expressions (2013)

Two experiments were conducted to investigate the role played by dynamic information in identifying facial expressions of emotion. Dynamic expression sequences were created by generating and displaying morph sequences which changed the face from neutral to a peak expression in different numbers of intervening intermediate stages, to create fast (6 frames), medium (26 frames), and slow (101 frames) sequences. In experiment 1, participants were asked to describe what the person shown in each sequence was feeling. Sadness was more accurately identified when slow sequences were shown. Happiness, and to some extent surprise, was better from faster sequences, while anger was most accurately detected from the sequences of medium pace. In experiment 2 we used an intensity-rating task and static images as well as dynamic ones to examine whether effects were due to total time of the displays or to the speed of sequence. Accuracies of expression judgments were derived from the rated intensities and the results were similar to those of experiment 1 for angry and sad expressions (surprised and happy were close to ceiling). Moreover, the effect of display time was found only for dynamic expressions and not for static ones, suggesting that it was speed, not time, which was responsible for these effects. These results suggest that representations of basic expressions of emotion encode information about dynamic as well as static properties.
One-Color Reversible Control of Photochromic Reactions in a Diarylethene Derivative: Three-Photon Cyclization and Two-Photon Cycloreversion by a Near-Infrared Femtosecond Laser Pulse at 1.28 μm (2011)

One-color control of colorization/decolorization reactions of diarylethene molecules was attained by using nonresonant high-order multiphoton absorption processes with a near-infrared (NIR) femtosecond laser pulse at 1.28 μm with 35 fs full width at half-maximum (fwhm). The intensity of a rather weak laser pulse (<1 nJ/pulse) can induce the simultaneous three-photon absorption leading to the colorization, while much weaker intensity induces two-photon absorption resulting in the decolorization. The spatial patterning concomitant with higher-order multiphoton absorption processes was also demonstrated.
Vegetative Propagation of <i>Pinus sylvestris</i> (1975)

Abstract Methods for the vegetative propagation of Pinus sylvestris L. from interfascicular shoots are described. Using 5‐year‐old plants the outgrowth of interfascicular shoots was promoted by removal of terminal and lateral buds; this response was augmented substantially by application of cytokinin, tri‐iodobenzoic acid, alar and morphactin alone and especially in combination. The rooting capacity of shoot cuttings from interfascicular shoots appeared to be largely determined by the state of growth of the stock plant. Cuttings from dormant stock plants subjected to short‐day treatment followed by a period of low temperature gave the best rooting, especially when the cuttings themselves had been cold‐stored prior to planting. Rooting was optimal when such cuttings were treated with a mixture of 25 mg/l of indolebutyric acid and 25 mg/l of napthaleneacetic acid as a 48 h basal soak, and were planted on a heated mistbench under extended illumination; over 90% of such cuttings could be rooted. These results are discussed in relation to bud activity, endogenous hormone levels and promoting tissue extracts also tested.
The U28 ORF of human herpesvirus-7 does not encode a functional ribonucleotide reductase R1 subunit (1999)

Herpesvirus ribonucleotide reductases, essential for the de novo synthesis of viral DNA, are composed of two non-identical subunits, termed R1 and R2. The U28 ORF from human herpesvirus-7 has been classified, by sequence comparisons, as a homologue of the R1 subunit from ribonucleotide reductase but no R2 ORF is present. Detailed analysis of the U28 amino acid sequence indicated that a number of essential R1 catalytic residues are absent. Cloning and expression of the U28 protein in E. coli and its subsequent characterization in subunit interaction and enzyme activity assays confirmed that it is not a functional equivalent of a herpesvirus R1. In the absence of the R2 gene, we propose that the R1 ORF has evolved a distinct, as yet unidentified, function not only in human herpesvirus-7 but also in other human betaherpes-viruses.
Nanofluidic Bubble Pump Using Surface Tension Directed Gas Injection (2002)

A new concept for liquid manipulation has been developed and implemented in surface-micromachined fluid channels. It is based on the surface tension directed injection of a gas into the liquid flow through micrometer-sized holes in the microchannel wall. The injected gas is directed to an exhaust by a cross-sectional asymmetry of the microchannel and thereby moves minute liquid volumes. Successful pumping experiments were performed with single stroke volumes of tens of picoliters at frequencies around 1 Hz. The minimum actuation pressure is 0.6 bar for a 2-microm channel height, in accordance with theoretical predictions.
Internet holes — Part 5a: 50 ways to attack your web systems (1995)

The Internet is now the world's most popular network and it is full of potential vulnerabilities. In this series of articles, we explore the vulnerabilities of the Internet and what you can do to mitigate them. This is the first of a two-part subsection in the Internet Holes series which considers a large number of ways to attack a system connected to the World Wide Web.
Coherent RF Error Statistics (1986)

RF error statistics for power, voltage, and phase are derived under the assumptions that the error component is coherently related to the desired signal, that its magnitude is constant, and that its phase is equally likely and uniformly distributed from 0 to 360°. The error statistics which result from these assumptions have nonzero mean values for power and voltage and standard deviations which differ significantly from those projected on the basis of Gaussian statistics that apply to incoherent errors. These statistics will be applied to typical component errors which arise in an overall system error budget.
Screening for <b> <i>N</i> </b> ‐glycosylated proteins by liquid chromatography mass spectrometry (2004)

In the last few years mass spectrometry has become the method of choice for characterization of post-translationally modified proteins. Whereas most protein chemical modifications are binary in the sense that only one change can be associated with a given residue, many different oligosaccharides can be attached to a glycosylation site residue. The detailed characterization of glycoproteins in complex biological samples is extremely challenging. However, information on N-glycosylation can be gained at an intermediary level. Here we demonstrate a procedure for mapping N-glycosylation sites in complex mixtures by reducing sample complexity and enriching glycoprotein content. Glycosylated proteins are selected by an initial lectin chromatography step and digested with endoproteinase Lys-C. Glycosylated peptides are then selected from the digest mixture by a second lectin chromatography step. The glycan components are removed with N-glycosidase F and the peptides digested with trypsin before analysis by on-line reversed-phase liquid chromatography mass spectrometry. Using two different lectins, concanavalin A and wheat germ agglutinin, this procedure was applied to human serum and a total of 86 N-glycosylation sites in 77 proteins were identified.
Are many Z-DNA binding proteins actually phospholipid-binding proteins? (1990)

We used a Z-DNA affinity column to isolate a collection of Z-DNA binding proteins from a high salt extract of Escherichia coli. We identified one of the major Z-DNA binding proteins of this fraction, not as a protein involved in gene regulation or genetic recombination, but rather as an outer membrane porin protein. We then showed that several other known phospholipid-binding proteins (bovine lung annexins and human serum lipoproteins) also bind much more tightly to Z-DNA than to B-DNA. In all cases, this Z-DNA binding was strongly blocked by competition with acidic phospholipids, such as cardiolipin. Our results raise the question whether many of the Z-DNA binding proteins previously isolated are actually phospholipid-binding proteins.
Analyzing credit evolution for credit-based incentive schemes in wireless mesh networks (2011)

Incentive mechanisms are often needed in wireless mesh networks (WMNs) so as to encourage nodes to relay or forward packets for other nodes. However, there is a lack of understanding on the interactions between the incentive mechanisms and the underlying routing protocols, and whether the network can sustain such traffic workload in the long run. In this paper, we propose a general mathematical framework via stochastic difference equations to model the interaction of incentive mechanisms and routing protocols. A credit evolution model is provided. Based on it, we study the expected credit variation of each node and use the Gini's coefficient to quantify the credit disparity among nodes. We also introduce the concept of differentiated pricing in the incentive mechanism to achieve credit equality among nodes so the WMN is more robust to sustain the traffic workloads.
Characterization of an X‐chromosome PCR–RFLP marker associated with fat deposition and growth in the pig (2004)

The X-chromosome, highly conserved within mammals, has been shown to contain major quantitative trait loci (QTL) for growth and fat deposition in the pig. We have discovered a BamHI polymerase chain reaction restriction fragment length polymorphism (PCR-RFLP) marker that was assigned to the porcine X-chromosome by two-point and multi-point linkage analysis following genotyping of a three-generation Berkshire by Yorkshire reference family. The marker was positioned 9 cM telomeric to SW2126 and 15.6 cM centromeric to SW1943. Sequence flanking the marker was found to have high similarity to existing database porcine DNA repeat elements. Association analyses of the BamHI marker for growth and meat quality traits in the reference family revealed significant association with marbling (P < 0.03), 10th rib back fat (P < 0.09) and total lipid percentage (P < 0.05), as well as with loin eye area (P < 0.04), average glycolytic potential (P < 0.03) and average lactate content (P < 0.04). Further studies are required to determine the X-chromosome functional gene affecting fat deposition and growth in the pig.
European soccer injuries (1992)

In 1 year, 715 patients with soccer injuries were registered and treated in the emergency department of Randers City Hospital. We did a prospective study of these patients using a questionnaire to determine the most common locations, types, mechanisms, and treatments of injury. Financial costs for society and the individual were also examined. Forty-nine percent of the injuries were to the joints; sprains and contusions were the most common types of injury, accounting for 46% and 25%, respectively. The majority of patients (64% of the men and 58% of the women) were injured during physical contact with another player. Most (63%) of the patients were treated in the emergency department and then released. Thirty-one percent had to be absent from work, but only 8% of the patients had a loss of income because of their injury. The average amount of work time lost was 5 days.

Multiuser MAC Protocols for 802.11n Wireless Networks (2009)

The emerging 802.11n standard establishes the integration of MIMO technology in WLANs with the goal of achieving high data rates. However there are still many open issues regarding MAC protocol design for MIMO based systems, especially in order to exploit the multiuser capabilities of the MIMO channel. In this paper we investigate practical solutions to implement multiuser downlink transmission in infrastructure 802.11n based WLANs. A low-complexity beamforming transmission technique is employed at the physical layer and four MAC schemes that vary in complexity and efficiency are presented and evaluated through computer simulations.
Programming wireless sensor networks with logical neighborhoods (2006)

Wireless sensor network (WSN) architectures often feature a (single) base station in charge of coordinating the application functionality. Although this assumption simplified the path to adoption of WSN technology, researchers are now being attracted by more decentralized architectures with multiple sinks and heterogeneous nodes. These scenarios are brought to an extreme in Wireless Sensor and Actor Networks (WSANs), where sensing and acting nodes collaborate in a decentralized fashion to implement complex control loops. In these settings, new programming abstractions are required to manage complexity and heterogeneity without sacrificing efficiency.In this paper we propose and define a logical neighborhood programming abstraction. A logical neighborhood includes nearby nodes that satisfy predicates over their static (e.g., type) or dynamic (e.g., sensed values) characteristics. The span of the neighborhood and the definition of its predicates are specified declaratively, along with requirements about the cost of the communication involved. Logical neighborhoods enable the programmer to "illuminate" different areas of the network according to the application needs, effectively replacing the physical neighborhood provided by wireless broadcast with a higher-level, application-defined notion of proximity.This paper presents the definition of a declarative language for specifying logical neighborhoods, highlighting its expressiveness, flexibility and simplicity. Moreover, although the language constructs are readily implemented using existing communication mechanisms, we briefly report about a novel routing scheme we expressly designed to support efficiently our abstractions.
The Influence of Longitudinal and Transverse Profile on the Load Capacity of Pivoted Pad Bearings (1960)

An extension of previous work on the effects of surface profile on the load capacity of pivoted pad thrust bearings. Numerical solutions are presented for a square pad having profiles consisting of (a) longitudinal curvature, (b) transverse curvature, and (c) a combination of (a) and (b). Improved load capacity over the flat pad with optimum pivot location is found for some operating conditions including the case of the centrally pivoted pad.
Purification and kinetic analysis of the two recombinant arogenate dehydrogenase isoforms of <i>Arabidopsis thaliana</i> (2002)

The present study reports the first purification and kinetic characterization of two plant arogenate dehydrogenases (EC 1.3.1.43), an enzyme that catalyses the oxidative decarboxylation of arogenate into tyrosine in presence of NADP. The two Arabidopsis thaliana arogenate dehydrogenases TyrAAT1 and TyrAAT2 were overproduced in Escherichia coli and purified to homogeneity. Biochemical comparison of the two forms revealed that at low substrate concentration TyrAAT1 is four times more efficient in catalyzing the arogenate dehydrogenase reaction than TyrAAT2. Moreover, TyrAAT2 presents a weak prephenate dehydrogenase activity whereas TyrAAT1 does not. The mechanism of the dehydrogenase reaction catalyzed by these two forms has been investigated using steady-state kinetics. For both enzymes, steady-state velocity patterns are consistent with a rapid equilibrium, random mechanism in which two dead-end complexes, E-NADPH-arogenate and E-NADP-tyrosine, are formed.
Nitric Oxide‐Mediated Intestinal Injury Is Required for Alcohol‐Induced Gut Leakiness and Liver Damage (2009)

The mechanism we reported for alcohol-induced intestinal barrier disruption in vitro - NO overproduction, oxidative tissue damage, leaky gut, endotoxemia, and liver injury - appears to be relevant in vivo in an animal model of alcohol-induced liver injury. That iNOS inhibitors attenuated all steps of this cascade suggests that prevention of this cascade in alcoholics will protect the liver against the injurious effects of chronic alcohol and that iNOS may be a useful target for prevention of ALD.
The Use of Trilostane for the Treatment of Alopecia X in Alaskan Malamutes (2005)

Three Alaskan malamutes with hair loss and slightly elevated blood concentrations of 17-hydroxyprogesterone after stimulation with adrenocorticotropic hormone (ACTH) were treated with trilostane. Trilostane, an inhibitor of 3 beta-hydroxysteroid dehydrogenase, was given twice daily at a dose of 3.0 to 3.6 mg/kg per day orally for 4 to 6 months. Routine ACTH stimulation tests were performed over 8 months to evaluate the degree of adrenal function suppression. Treatment with trilostane led to complete hair regrowth in all three dogs within 6 months. No adverse effects associated with trilostane were recognized.
New Prediction Modes for Parallel Processing of H.264/AVC (2011)

New coding algorithm is required to be compatibleto the improvement of the new trend of hardware devices.This work proposes a novel parallel processing algorithm forH.264/AVC which is dedicated to GPU implementation. Firstly,the original pixel data is used in the rate-distortion optimization(RDO) process instead of the reconstructed pixel data to realizethe complete MB-level parallel processing of INTRA coding.It can help to parallel encode all the MB in one frame inthe same time on GPU. Next, a new temporal predictionconcept is introduced in the traditional spatial prediction tocompensate the weak point of individual usage of spatial ortemporal prediction. The new algorithm uses the selected blockin the previous frame as the reference data to perform spatialprediction. The simulation results show that when using theoriginal pixel in the RDO process it will induce slight PSNRloss. However, when the proposed new modes are introducedthe RD-curve shows about 1dB improvement than the originalH.264/AVC.
GPU/CPU Work Sharing with Parallel Language XcalableMP-dev for Parallelized Accelerated Computing (2012)

In this paper, we propose a solution framework to enable the work sharing of parallel processing by the coordination of CPUs and GPUs on hybrid PC clusters based on the high-level parallel language XcalableMPdev. Basic XcalableMP enables high-level parallel programming using sequential code directives that support data distribution and loop/task distribution among multiple nodes on a PC cluster. XcalableMP-dev is an extension of XcalableMP for a hybrid PC cluster, where each node is equipped with accelerated computing devices such as GPUs, many-core environments, etc. Our new framework proposed here, named XcalableMP-dev/Star PU, enables the distribution of data and loop execution among multiple GPUs and multiple CPU cores on each node. We employ a Star PU run-time system for task management with dynamic load balancing. Because of the large performance gap between CPUs and GPUs, the key issue for work sharing among CPU and GPU resources is the task size control assigned to different devices. Since the compiler of the new system is still under construction, we evaluated the performance of hybrid work sharing among four nodes of a GPU cluster and confirmed that the performance gain by the traditional XcalableMP-dev system on NVIDIA CUDA is up to 1.4 times faster than GPU-only execution.

SEPSIS-INDUCED ALTERATIONS IN PYRUVATE DEHYDROGENASE COMPLEX ACTIVITY IN RAT SKELETAL MUSCLE (1996)

The pyruvate dehydrogenase (PDH) complex undergoes reversible phosphorylation catalyzed by a PDH kinase (inactivating) and a PDH phosphatase (activating). In skeletal muscle, a decreased proportion of PDH complex in the active, nonphosphorylated form (PDHa) limits glucose oxidation and promotes the conversion of pyruvate to lactate. Increased lactate formation with the accompanying hyperlactatemia is a frequent metabolic complication of sepsis. The time course for inactivation of the PDH complex in skeletal muscle during sepsis was contrasted with changes in PDHa during sterile inflammation 3,7, or 14 days following the implantation of the foreign body nidus. Total PDH complex activity was not altered in any of the conditions examined. Sepsis, but not sterile inflammation, caused a reduction in the muscle PDHa measured 3 or 7 days following induction of sepsis. The inhibition of the muscle PDHa during sepsis was associated with a sustained hyperlactatemia. PDH kinase activity measured in extracts of mitochondria was enhanced twofold during this period. Fourteen days after induction of sepsis, there were no differences in the PDHa or plasma lactate concentrations in septic rats compared with either control or sterile inflammation. Furthermore, the PDH kinase activity was decreased to values observed in control values. The results are consistent with the hypothesis that a reduced PDHa in skeletal muscle during sepsis is responsible, in part, for the hyperlactatemia characteristic of septic hypermetabolism. Furthermore, the results provide evidence that the decrease in PDHa results from a stable stimulation of PDH kinase activity.
Lateral motion of fluorescently labeled acetylcholine receptors in membranes of developing muscle fibers. (1976)

We have made direct, quantitative measurements of the lateral motion and age-dependent distribution of acetylcholine receptors (AChR) on the surface of rat myotubes in primary culture. AChR were fluorescently marked with tetramethylrhodamine-labeled alpha-bungarotoxin and AChR lateral motion was measured by the fluoresence photobleaching recovery technique. We found two coexisting distinct classes of AChR: (i) mobile, uniformly distributed AChR that appear on all myotubes shortly after fusion from myoblasts; and (ii) immobile, dense, highly granular AChR in patches of 10-60 mum size that appear shortly after fusion and disappear after myotubes have become extensively interconnected. In addition, evidence of turnover of AChR labeled with tetramethylrhodamine-alpha-bungarotoxin is seen in the gradual internalization of surface fluorescence within 36 hr after labeling. The relevance of these results to an understanding of the membrane dynamics and localization of muscle AChR is discussed.
