Towards ad hoc contextual services for pervasive computing (2006)

Context-awareness is a key challenge for pervasive computing, as it is a prime requirement towards delivering applications to users in a way that best matches user requirements, digital resources availability and physical conditions. However, enabling anytime, anywhere context-awareness, as targeted by pervasive computing, is further challenged by the openness of the environment, which requires making available context information in various computing environments. This then calls for the ad hoc networking of context sources and of context-aware applications, so that applications may always benefit from a context knowledge base, although it may be more or less rich, depending on the specific environment. Building upon the context management literature, and the Service-Oriented Architecture (SOA) paradigm that is a major enabler of open ad hoc networking, this paper sketches key context-aware system concepts that need be incorporated in the SOA style towards enabling context-aware services for pervasive computing.
Simultaneous connection management and protection in a distributed multilevel security environment (2004)

The Naval Postgraduate School Center for Information Systems Security Studies and Research (CISR) is designing and developing a distributed multilevel secure (MLS) network known as the Monterey Security Architecture (MYSEA). MYSEA will permit the delivery of unmodified commercial off the shelf productivity software applications and data from a large number of single-level network domains (e.g., NIPRNET, SIPRNET, JWICS) to a trusted distributed operating environment that enforces MLS policies. The analysis and development of a communications framework necessary to support connections between multiple MLS servers and a set of high assurance network appliances supporting simultaneous access to multiple single level networks and their concurrent connection management is required to fulfill the goal of MYSEA. To enable this functionality, modifications to the existing MYSEA server, the development of a new high assurance communications security device - the Trusted Channel Module (TCM), and the implementation of a trusted channel between the MYSEA server and the TCM is required. This document specifies a framework for incorporating the high level design of the TCM, several trusted daemons and databases, plus the incorporation of a trusted channel protocol into MYSEA to enable a distributed MLS environment.
A 31.3-dBm Bulk CMOS T/R Switch Using Stacked Transistors With Sub-Design-Rule Channel Length in Floated p-Wells (2007)

A 31.3-dBm 900-MHz bulk CMOS T/R switch with transmit (TX) and receive (RX) insertion losses of 0.5 and 1.0 dB and isolation of 29 dB is demonstrated. The switch utilizes a floating-body technique, feed-forward capacitors, and 3-stack 3.3-V MOSFETs with 0.26-mum sub-design-rule (SDR) channel length. Using these, a 28-dBm 2.4-GHz T/R switch with TX and RX insertion losses of 0.8 and 1.2 dB, and isolation of 24 dB is also demonstrated. The power handling capability is limited by an abrupt output power drop before reaching the normal 1-dB compression point. The circuits are implemented in the UMC 130-nm mixed-mode triple-well CMOS process.
Inhibition of platelet adherence to damaged surface of rabbit aorta. (1975)

A method has been developed for quantitative measurement of adherence of rabbit platelets to the damaged intimal surface of everted segments of rabbit thoracic aorta. Platelets were labeled with 51Cr, washed, and resuspended in Tyrode solution containing 0.35 per cent albumin and apyrase. This suspending medium contains physiologic concentrations of calcium and magnesium; apyrase degrades any ADP lost from the platelets or from the damaged wall. Everted aorta segments were rotated in the platelet suspensions. Neither platelet aggregation nor lysis occurred and the platelets adhered to the subendothelium either as individual platelets or as a single layer. Damage caused by scraping the everted segments with a scalpel blade increased adherence 50-fold. Acetylsalicylic acid (ASA) in vitro, or administered orally to the rabbits from which platelet suspensions were prepared, significantly reduced the number of platelets adherent to the damaged aorta wall. ASA affected only the platelets, and did not affect the damaged wall. Platelet adherence to the damaged wall was also reduced by the use of 4 per cent albumin in the suspending medium, or by the addition of citrate. Adherence of platelets resuspended in citrated plasma was low and further inhibition by ASA was not demonstrable. ASA may affect two aspects of thrombus formation: platelet adherence to subendothelial structures and the platelet release reaction induced by collagen (and possibly by other subendothelial structures). These studies show that ASA has a marked effect on adherence of platelets to subendothelium under conditions in which aggregation and thrombus formation are prevented.
Prevotella lacticifex sp. nov., isolated from the rumen of cows (2022)

The genus <i>Prevotella</i> plays an important role in polysaccharide degradation and fermentation in the rumen. To further understand the function of the phylogenetically diverse genus <i>Prevotella</i>, it is necessary to explore the individual characteristics at the species level. In this study, Gram-negative anaerobic bacterial strains isolated from the rumen of Holstein cows were identified. Strain R5019<sup>T</sup> was classified within the genus <i>Prevotella</i> based on 16S rRNA gene sequence-based phylogenetic analysis. The values of 16S rRNA gene sequence similarity, average nucleotide identity and digital DNA-DNA hybridization between strain R5019<sup>T</sup> and its phylogenetically nearest species <i>Prevotella multisaccharivorax</i> PPPA20<sup>T</sup> were 89.8, 82.6, and 29.3 %, respectively. The genome size of R5019<sup>T</sup> was estimated to be ca. 4.19 Mb with a genomic G+C content of 49.5 mol%. The major cellular fatty acids and menaquinones were C<sub>15 : 0</sub> anteiso and C<sub>17 : 0</sub> anteiso and MK-11 and MK-12, respectively. Succinate, lactate, malate, acetate and formate were produced as the fermentation end products using glucose. Based on phylogenetic, physiological, biochemical and genomic differences between 11 strains and other phylogenetically related <i>Prevotella</i> species, a novel species, <i>Prevotella lacticifex</i> sp. nov., is proposed within the genus <i>Prevotella</i>. The type strain is R5019<sup>T</sup> (=JCM 34664<sup>T</sup>=DSM 112675<sup>T</sup>).
HYBRID ENSEMBLE METHOD FOR THE UU COLLISION TERM (2001)

We present an efficient way to evaluate the Ühling–Uhlenbeck (UU) collision term in the case of semi-classical dynamics. We focus on finite fermionic systems such as small metal clusters, which we recently pointed out the importance of the UU collision term for the electronic dynamics. We show, how far the hybrid method, which lies between the full and the parallel ensemble methods, allows an efficient and accurate treatment of a Boltzmann–like collision term. We finally give a guideline to define the best parameter of the hybrid ensemble method for a given cluster size.
Effect of Na+ ion concentration on tRNA conformation in solution studied by laser Raman spectroscopy (1975)

Abstract Raman spectra of baker's yeast tRNA in NaCl aqueous solutions were measured as a function of sodium ion concentration throughout the 0–1.0 M range. Strong variations in intensity of the various bands allowed observation of the ionic strength‐dependent conformational transitions of the tRNA. The experimental data obtained point to the existence of five distinct conformations of the tRNA molecules in the range of Na + concentration investigated.
Germanium diffusion in polysilicon emitters of SiGe heterojunction bipolar transistors fabricated by germanium implantation (2002)

A study is made of germanium diffusion in polysilicon emitters of SiGe heterojunction bipolar transistors made by germanium implantation. Implanted Ge is found to diffuse from the single-crystal silicon substrate into deposited polysilicon emitter layers during rapid thermal anneal at 1045 °C. Measurements of germanium diffusivity in polycrystalline silicon are reported at temperatures between 800 and 900 °C and modeled by an Arrhenius relationship with a preexponential factor of Do=0.026±0.023 cm2/s and an activation energy of E=2.59±0.36 eV. The measured diffusivity in polycrystalline silicon is ≈104 times larger than that reported for single-crystal silicon. It is hypothesised that germanium diffusion in polysilicon occurs by diffusion along grain boundaries.
A Novel Optical CDMA Modulation Scheme: Code Cycle Modulation. (2006)

Abstract — Recently there has been some interest in optical CDMA (OCDMA) for optical networks. A major drawback of OCDMA systems is their low spectral efficiency. This paper explores a novel modulation scheme for OCDMA systems which increases the spectral efficiency called code-cycle modulation (CCM) which uses different cyclic shifts of the spreading sequence assigned to each user to transmit an M-ary information. While the idea of using M-ary OCDMA modulation has been proposed using other means, most of these modulation schemes need M different receiver units to recover the data which causes complexity and power issues in the receiver. The advantage of our scheme is that we propose a supporting receiver architecture which doesn’t suffer from complexity and power issues as mentioned above. In the rest of the paper we analyze the performance of this modulation scheme. I.
Road sign recognition for automatic inventory systems (2011)

This paper describes a system that enables recognition of road signs from image sequences previously obtained from a vehicle equipped with a variety of sensors. The first step uses colour and shape analysis to determine the regions of the image where potential road signs may be located. The second step uses a geometric model finder to recognize and classify the type of sign.
Structural basis of von Willebrand factor binding to platelet glycoprotein Ib and collagen. Effects of disulfide reduction and limited proteolysis of polymeric von Willebrand factor. (1986)

von Willebrand factor (vWF) is a large, multimeric glycoprotein that helps platelets adhere to vascular subendothelium. Although vWF binding to platelet receptors and connective tissue constituents is of fundamental importance in adhesion, there is little information regarding the nature of these vWF binding sites. In this paper, we have compared the structural requirements for vWF binding with platelet glycoprotein Ib (GpIb), heparin, and collagen and have shown that fragments derived from large vWF multimers retain biologic activity. We have shown that a 440,000-D subunit produced by disulfide reduction and alkylation of vWF polymer binds to platelet GpIb. When analyzed by polyacrylamide gel electrophoresis and Sepharose CL6B chromatography, the 440,000-D vWF oligomer is a dimer of the 220,000 subunit of fully reduced native vWF. This vWF dimer competes with 125I-vWF for binding to GpIb with an IC50 of 100 micrograms/ml (227 nM). The GpIb binding domain on vWF was further localized by digestion of native vWF polymers with Staphylococcal V8 protease. A 285,000-D fragment of vWF multimer was separated from heterogeneous 210,000-225,000-D fragments by its ability to bind to heparin. The 285,000-D fragment that bound to heparin Sepharose was composed of two disulfide-linked 175,000- and 115,000-D polypeptides. The heterogeneous fragments contained disulfide-linked 96,000, 66,000, and 53,000-D polypeptides when analyzed on polyacrylamide gel electrophoresis. The 285,000-D fragment competed with 125I-vWF for binding to GpIb with an IC50 of 22 micrograms/ml (77 nM), while the other fragments did not compete for binding. Neither the vWF dimer nor the proteolytic fragments competed with native 125I-vWF polymer for binding to collagen.

This paper proposes the relative method which is used to calculate and monitor dielectric loss of transformer bushing and designs the on-line monitoring device, through the data acquiring form the on-line monitoring instrument which are installed in the transformer of substation shows that this method has high precision, strong anti-interference ability.
Increased Myocardial Expression of Osteopontin in Patients with Advanced Heart Failure (2002)

The expression of the adhesion protein osteopontin (OP) is associated with cardiac hypertrophy and is significantly increased after transition to heart failure in experimental animal models. We, therefore, hypothesized that OP could be upregulated in heart failure in humans. In the present study, we investigated the expression of OP in myocardial biopsies obtained from patients with heart failure due to dilated cardiomyopathy (mean LVEF=30.3+/-4.4%, mean+/-S.D., n=10, group A) compared to patients with a normal left-ventricular ejection fraction (mean LVEF=61+/-11.2%, n=9; group B). Myocardial immunoreactivity for OP was examined using two different antibodies against OP. The expression of cardiac myocyte OP was significantly upregulated in group A in comparison to group B (P<0.0001). Both groups also displayed OP immunoreactivity in non-myocytes, including vascular smooth muscle cells and cardiac fibroblasts (P=not significant). Statistical analysis revealed a significant correlation of increased OP immunoreactivity in cardiac myocytes of patients with impaired left ventricular function, assessed by hemodynamic data (LVEF, RVEF, LVESVI, LVEDVI and LVEDP, R=-0.828, -0.671, 0.751, 0.685 and 0.461, respectively; all P<0.05). Furthermore, OP expression correlated with cardiac myocyte hypertrophy (mean diameter 21.0+/-1.8 microm in group A and 16.6+/-2.1 microm in group B; P<0.0001). In conclusion, the present study indicates, that factors and/or mechanisms involved in heart failure in patients with dilated cardiomyopathy, lead to induction of OP expression in humans.

DOLORES E. LITTLE (B.S.N., M.N., University of Washington) is assistant professor of medical and surgical nursing at the University of Washington School of Nursing, Seattle. She and two psychiatric instructors at Washington, Betty Pesznecker and Joan Baker, prepared the nursing care study on which “Mrs. Reynolds” is based.
Involvement of β3-Adrenoceptor in the Relaxation Response in Guinea Pig Taenia Caecum (1994)

beta-Adrenoceptors in the guinea pig taenia caecum were investigated by measuring relaxation responses to agonists and by a radioligand binding assay using [3H]CGP 12177. The rightward shift of the isoprenaline concentration-response curve was observed by butoxamine, a beta 2-selective antagonist, and the pA2 value for butoxamine was 6.46. In control preparations, catecholamines caused relaxation with the following rank order of potency: isoprenaline > adrenaline > noradrenaline. However, in the presence of 10(-6) M phentolamine, 3 x 10(-4) M atenolol and 10(-4) M butoxamine, the rank order of potency of the agonists was: isoprenaline > noradrenaline > adrenaline. CGP 12177 caused graded relaxation of the guinea pig taenia caecum, and this response was not influenced by 10(-6) M phentolamine, 3 x 10(-4) M atenolol, 10(-4) M butoxamine or 10(-6) M propranolol. The Scatchard plot of the specific [3H]CGP 12177 binding to microsomal fractions from the guinea pig taenia caecum showed two affinity sites of the receptor: high affinity (KD = 0.64 nM) and low affinity (KD = 142.21 nM) sites. The pKD value of the high affinity site of [3H]CGP 12177 was in agreement with its pA2 value, and that of the low affinity site was in agreement with its pD2 value. These results suggest that isoprenaline-, noradrenaline- and adrenaline-induced relaxations of the guinea pig taenia caecum predominantly involve beta 2- and beta 3-adrenoceptors, whereas CGP 12177-induced relaxation is mediated solely through beta 3-adrenoceptors.
Governor principle for increased safety and economy on vessels with diesel-electric propulsion (2013)

In this paper, a governor principle for marine dieselelectric power plants with a normal and an emergency mode is proposed. In the normal mode, the governor is tuned such that the variations in the electric frequency are weighed against operational costs such as specific fuel consumption, pollutant emissions and wear-and-tear of the diesel engine due to thermal variations. In emergency mode, the governor disregards the operational costs and attempts to keep the frequency as steady as possible. This leads to larger margins to the under-frequency condition and therefore reduces the risk of blackout. It also allows for a more reliable synchronization of additional generating sets to the electric grid. Because the emergency mode is entered under abnormal conditions only, the overall increase in operational costs resulting from this addition is negligible. The governor is implemented as a receding horizon controller.

Question Part Relevance and Editing for Cooperative and Context-Aware VQA (C2VQA) (2017)

Visual Question Answering (VQA), a task that requires the ability to provide an answer to a question given an image, has recently become an important benchmark for computer vision. However, current VQA approaches are unable to adequately handle questions that are "irrelevant", such as asking about a cat for an image that has no cat. To date, only one paper has examined the idea of question relevance in VQA, using a binary classification model to assign a relevancy to the entire question / image pair. Truly robust VQA models, however, must not only identify potentially irrelevant questions, but also discover the source of irrelevance and seek to correct it. We therefore introduce two novel problems, question part relevance and question editing, and approaches for solving each problem. In question part relevance, our models go beyond binary question relevance by assigning a classification probability to the portion of the question that is irrelevant. The best question part relevance classifier is later used in question editing to rank possible corrections to the irrelevant portion of given questions. Two custom datasets are developed for these problems using the Visual Genome dataset as a source. Our best models show promising results in these novel tasks over baseline approaches and models adapted from whole-question relevance classification. This work contributes directly to the development of more context-aware and cooperative VQA models, dubbed C2VQA.
Mesomorphism of cis-trans-isomers mixtures of 4-butyl-cyclohexanecarboxylic acid (1997)

In response to most stressors, fish will elicit a generalized physiological stress response, which involves the activation of the hypothalamic-pituitary-interrenal axis (HPI). As in other vertebrates, this generalized stress response comprises physiological responses that are common to a wide range of environmental, physical and biological stressors. Recently, several families of heat shock proteins (hsps) have been proposed as indicators of a generalized stress response at the cellular level. Recent findings that hsp levels, in various fish tissues, respond to a wide range of stressors have supported the use of these proteins as indicators of stressed states in fish. However, the cellular stress response can vary, for example, according to tissue, hsp family and type of stressor. This brief overview of these responses in fish asks the question of whether changes in levels and families of hsps can be used as a suitable indicator of stressed states in fish. By casting this question in the context of the well-established generalized physiological stress response in fish, we argue that the use of hsps as indicators of stressed states in fish in general is premature.
Sex-specific effects of microbiome perturbations on cerebral Aβ amyloidosis and microglia phenotypes (2019)

We demonstrated that an antibiotic cocktail (ABX)-perturbed gut microbiome is associated with reduced amyloid-β (Aβ) plaque pathology and astrogliosis in the male amyloid precursor protein (<i>APP)<sub>SWE</sub></i> /presenilin 1 <i>(PS1)<sub>ΔE9</sub></i> transgenic model of Aβ amyloidosis. We now show that in an independent, aggressive <i>APP<sub>SWE</sub>/PS1<sub>L166P</sub></i> (APPPS1-21) mouse model of Aβ amyloidosis, an ABX-perturbed gut microbiome is associated with a reduction in Aβ pathology and alterations in microglial morphology, thus establishing the generality of the phenomenon. Most importantly, these latter alterations occur only in brains of male mice, not in the brains of female mice. Furthermore, ABX treatment lead to alterations in levels of selected microglial expressed transcripts indicative of the "M0" homeostatic state in male but not in female mice. Finally, we found that transplants of fecal microbiota from age-matched APPPS1-21 male mice into ABX-treated APPPS1-21 male restores the gut microbiome and partially restores Aβ pathology and microglial morphology, thus demonstrating a causal role of the microbiome in the modulation of Aβ amyloidosis and microglial physiology in mouse models of Aβ amyloidosis.
Ingress noise cancellation for the upstream channel in broadband cable access systems (2003)

We present a receiver architecture for transmission over the upstream channel of hybrid fiber coax (HFC) networks affected by ingress noise and channel distortion. The receiver uses a noise prediction algorithm. It is shown that the proposed receiver makes it possible to transmit a QPSK signal over a cable channel affected by three interferers with an individual power of -10 dBc, with an SNR degradation of only 1.8 dB. The SNR degradation corresponding to 16-QAM transmission over a channel affected by three interferers of -15 dBc is 2.1 dB. We also describe an adaptation technique that makes use of empty time slots to track changes of the ingress noise continuously. The noise canceller involves only a small additional complexity.
