Guaranteeing High Availability Goals for Virtual Machine Placement (2011)

The placement of virtual machines (VMs) on a cluster of hosts under multiple constraints, including administrative (security, regulations) resource-oriented (capacity, energy), and QoS-oriented (performance) is a highly complex task. We define a new high-availability property for a VM; when a VM is marked as k-resilient, as long as there are up to k host failures, it should be guaranteed that it can be relocated to a non-failed host without relocating other VMs. Together with Hardware Predictive Failure Analysis and live migration, which enable VMs to be evacuated from a host before it fails, this property allows the continuous running of YMs on the cluster despite host failures. The complexity of the constraints associated with k-resiliency, which are naturally expressed by Second Order logic statements, prevented their integration into the placement computation until now. We present a novel algorithm which enables this integration by transforming the k-resiliency constraints to rules consumable by a generic Constraint Programming engine, prove that it guarantees the required resiliency and describe the implementation. We provide some preliminary results and compare our high availability support with naive solutions.
A method for detecting text of arbitrary shapes in natural scenes that improves text spotting (2019)

Understanding the meaning of text in images of natural scenes like highway signs or store front emblems is particularly challenging if the text is foreshortened in the image or the letters are artistically distorted. We introduce a pipeline-based text spotting framework that can both detect and recognize text in various fonts, shapes, and orientations in natural scene images with complicated backgrounds. The main contribution of our work is the text detection component, which we call UHT, short for UNet, Heatmap, and Textfill. UHT uses a UNet to compute heatmaps for candidate text regions and a textfill algorithm to produce tight polygonal boundaries around each word in the candidate text. Our method trains the UNet with groundtruth heatmaps that we obtain from text bounding polygons provided by groundtruth annotations. Our text spotting framework, called UHTA, combines UHT with the state-of-the-art text recognition system ASTER. Experiments on four challenging and public scene-text-detection datasets (Total-Text, SCUT-CTW1500, MSRA-TD500, and COCO-Text) show the effectiveness and generalization ability of UHT in detecting not only multilingual (potentially rotated) straight but also curved text in scripts of multiple languages. Our experimental results of UHTA on the Total-Text dataset show that UHTA outperforms four state-of-the-art text spotting frameworks by at least 9.1 percent points in the F-measure, which suggests that UHTA may be used as a complete text detection and recognition system in real applications.
Performance of enhanced multi-code spread slotted Aloha (EMCSSA) with voice and data (2003)

We present an analytical framework which enables the MCSSA protocol defined and analyzed by Dastangoo, Vojcic and Daigle (see IEEE GLOBECOM '98) to support differentiated services (e.g., voice and data). The underlying principles to the MCSSA protocol consist of two elements. The first element concerns the users' random selection from a finite number of resources (i.e., channels or spread spectrum (SS) codes). The second is the simultaneous transmission of users' packets. These elements are realized through two stages of packet acquisition (Stage-I) and packet transmission (Stage-II). Therefore, a successful transmission depends not only upon the success in Stage-I, but also the success in Stage-II. To support multi-traffic classes requires several modifications to Stage-I of the MCSSA protocol. Naturally, voice traffic must be given preferential treatment over the data traffic, since the quality of service (QoS) of the former suffers more from excess access/queueing delays. In EMCSSA, we develop a priority mechanism in Stage-I which enables the voice users to contend, acquire, and reserve SS codes for the duration of their calls. Since the users' access to the resources in EMCSSA is distributed on a per-slot basis, each user's activity should be known to all. This is realized through a multi-level information feedback in Stage-I. We set the stage for both infinite population (Poisson/binomial model) and finite population (Markov model) cases. However, we only present the former. To assess the performance of the proposed protocol, we evaluate a commonly used performance metric: the average throughput.
Optical properties investigations of organic Alq/sub 3/ layers doped by DCM (2003)

We present the study of optical emission properties carried out on Alq/sub 3/ organic solutions and evaporated films prepared by doping with dye molecules of DCM. The maxima of spontaneous emission spectral characteristics of Alq/sub 3/:DCM films measured by photo- and electroluminescence shifts towards the higher wavelengths from 608 - 660 nm with simultaneous decrease in spectral intensities within the investigated DCM doping concentration range of 0.9 11%, respectively. The maximum emission intensity was observed at DCM doping concentration around 1% causing peak emission near 628 nm by optical pumping. Optically excited amplified spontaneous emission and laser spectrum showing evenly spaced resonant cavity modes with preferential emission peak at 621.4 nm have been measured on waveguide structures prepared onto GaAs substrate.
Stress Corrosion Cracking of Zircaloy-2 Cladding in Iodine Vapor (1977)

Iodine stress corrosion cracking of Zircaloy-2 cladding under static tensile stress has been studied over the temperature range of 250~450°C. The lowest iodine concentration required to cause cracking was 0.15 mg iodine per cm3 free volume in test ampoule at 300°C, and 1.1 mg/cm' at 350°C. The minimum circumferential plastic strain to cause failure was about 0.4% for specimen tubes possessing high cracking susceptibility. Softer tubes tolerate more circumferential deformation before they failed. This is attributed to greater margin retained for work hardening, rather than to smaller residual tensile hoop stress. Cracking was also inhibited by the presence of oxygen in the iodine atmosphere, the threshold partial pressures being 28 torr at 300°C and 9 torr at 350°C. Scanning electron micrographs of the fractured surfaces revealed brittle transgranular fracture carrying river patterns on part of the cleavage facets.
Pattern Transformation Triggered by Deformation (2007)

Periodic elastomeric cellular solids are subjected to uniaxial compression and novel transformations of the patterned structures are found upon reaching a critical value of applied load. The results of a numerical investigation reveal that the pattern switch is triggered by a reversible elastic instability. Excellent quantitative agreement between numerical and experimental results is found and the transformations are found to be remarkably uniform across the samples. It is proposed that the mechanism will also operate at much smaller scales opening the possibility for imprinting complex patterns at the nanoscale or switching photonic and phononic crystals in a controlled way.
Spectral–Spatial Gabor Surface Feature Fusion Approach for Hyperspectral Imagery Classification (2018)

Since the spatial distribution of surface materials is usually regular and locally continuous, it is reasonable to utilize the spectral and spatial information for the hyperspectral image classification. In this paper, a spectral-spatial Gabor surface feature (GSF) fusion approach has been proposed for hyperspectral image classification. First, Gabor magnitude pictures (GMPs) are extracted by applying a set of predefined 2-D Gabor filters to hyperspectral images. Second, the GSF has been extended to the spectral-spatial domains to comply with the 3-D structure of hyperspectral imagery, called 3-DGSF, which utilizes the first-order derivative of GMPs. Meanwhile, a classic superpixel segmentation method, called simple linear iterative clustering (SLIC), is adopted to divide the original hyperspectral image into disjoint superpixels. Third, principal component analysis is adopted to reduce the dimensionality of each extracted 3-DGSF feature cube. Next, a support vector machine classifier is applied on each reduced 3-DGSF features, and the majority voting strategy is used to obtain the classification results. Finally, the superpixel map obtained by SLIC is used to regularize the classification map, and thus, the proposed approach is named as S3-DGSF. Extensive experiments on three real hyperspectral data sets have demonstrated the higher performance of the proposed S3-DGSF approach over several state-of-the-art methods in the literature.
Factor V Leiden (FV R506Q) in Families with Inherited Antithrombin Deficiency (1996)

We investigated the presence of the gene mutation of factor V, FV R506Q or factor V Leiden, responsible for activated protein C resistance, in DNA samples of 127 probands and 188 relatives from 128 families with antithrombin deficiency. The factor V mutation was identified in 18 families. Nine families were available to assess the mode of inheritance and the clinical relevance of combined defects. The factor V and antithrombin genes both map to chromosome 1. Segregation of the defects on opposite chromosomes was observed in three families. Co-segregation with both defects on the same chromosome was demonstrated in four families. In one family a de novo mutation of the antithrombin gene and in another a crossing-over event were the most likely explanations for the observed inheritance patterns. In six families with type I or II antithrombin deficiency (reactive site or pleiotropic effect), 11 of the 12 individuals with both antithrombin deficiency and the factor V mutation developed thrombosis. The median age of their first thrombotic episode was 16 years (range 0-19); this is low compared with a median age of onset of 26 years (range 20-49) in 15 of 30 carriers with only a defect in the antithrombin gene. One of five subjects with only factor V mutation experienced thrombosis at 40 years of age. In three families with type II heparin binding site deficiencies, two of six subjects with combined defects experienced thrombosis; one was homozygous for the heparin binding defect. Our results show that, when thrombosis occurs at a young age in antithrombin deficiency, the factor V mutation is a likely additional risk factor. Co-segregation of mutations in the antithrombin and factor V genes provides a molecular explanation for severe thrombosis in several generations. The findings support that combinations of genetic risk factors underly differences in thrombotic risk in families with thrombophilia.
SU‐F‐T‐628: An Evaluation of Grid Size in Eclipse AcurosXB Dose Calculation Algorithm for SBRT Lung (2016)

Purpose: purpose of this study is to evaluate the effect of grid size in Eclipse AcurosXB dose calculation algorithm for SBRT lung. Methods: Five cases of SBRT lung previously treated have been chosen for present study. Four of the plans were 5 fields conventional IMRT and one was Rapid Arc plan. All five cases have been calculated with five grid sizes (1, 1.5, 2, 2.5 and 3mm) available for AXB algorithm with same plan normalization. Dosimetric indices relevant to SBRT along with MUs and time have been recorded for different grid sizes. The maximum difference was calculated as a percentage of mean of all five values. All the plans were IMRT QAed with portal dosimetry. Results: The maximum difference of MUs was within 2%. The time increased was as high as 7 times from highest 3mm to lowest 1mm grid size. The largest difference of PTV minimum, maximum and mean dose were 7.7%, 1.5% and 1.6% respectively. The highest D2‐Max difference was 6.1%. The highest difference in ipsilateral lung mean, V5Gy, V10Gy and V20Gy were 2.6%, 2.4%, 1.9% and 3.8% respectively. The maximum difference of heart, cord and esophagus dose were 6.5%, 7.8% and 4.02% respectively. The IMRT Gamma passing rate at 2%/2mm remains within 1.5% with at least 98% points passing with all grid sizes. Conclusion: This work indicates the lowest grid size of 1mm available in AXB is not necessarily required for accurate dose calculation. The IMRT passing rate was insignificant or not observed with the reduction of grid size less than 2mm. Although the maximum percentage difference of some of the dosimetric indices appear large, most of them are clinically insignificant in absolute dose values. So we conclude that 2mm grid size calculation is best compromise in light of dose calculation accuracy and time it takes to calculate dose.
A novel class of serial-parallel redundant signed-digit multipliers (2002)

Digit-serial multiplier structures (operating most significant digit first with a redundant radix 2 representation) are introduced. They achieve optimal performance with regard to the latency-throughput tradeoff. Their hardware complexity is shown to be lower than classical multipliers operating least significant bit first. A general derivation shows them to be the only canonical structures having these properties.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Battery-powered thin film deposition process for coating telescope mirrors in space (2016)

Aluminum films manufactured in the vacuum of space may increase the broadband reflectance response of a space telescope operating in the EUV (50-nm to 115-nm) by eliminating absorbing metal-fluorides and metal-oxides, which significantly reduce aluminum’s reflectance below 115-nm. Recent developments in battery technology allow small lithium batteries to rapidly discharge large amounts of energy. It is therefore conceivable to power an array of resistive evaporation filaments in a space environment, using a reasonable mass of batteries and other hardware. This paper presents modeling results for coating thickness as a function of position, for aluminum films made with a hexagonal array of battery powered evaporation sources. The model is based on measured data from a single battery-powered evaporation source.
DECONTAMINATION IN THE EVENT OF A CHEMICAL OR RADIOLOGICAL TERRORIST ATTACK (2006)

This paper analyzes technologies and methods that can be used to decontaminate buildings and structures affected by chemical or radiological terrorist attacks. Technologies are classified into three categories, including mechanical and physical methods, chemical methods, and biological methods (including natural degradation/attenuation). They are analyzed in terms of their effectiveness with regards to specific types of chemical or radiological agents, their status of application, equipment availability and associated costs. Technology limitations and gaps are identified. Needs for further technological research, development and evaluation are also discussed.
Nitric oxide regulates endotoxin-induced TNF-alpha production by human neutrophils. (1994)

We studied the effect of nitric oxide on LPS-induced TNF-alpha production by human neutrophils. Human neutrophils exposed to LPS and IFN-gamma did not show measurable increases in intracellular cyclic GMP (cGMP). However, cGMP increased upto 30-fold (p < 0.01) in neutrophils incubated with both sodium nitroprusside (SNP), an exogenous source of nitric oxide, and N-acetylcysteine (NAC), which increases the bioavailability of nitric oxide; this increase indicates that neutrophils contain a nitric oxide-sensitive guanylate cyclase. SNP, with or without NAC, did not increase TNF-alpha production in human neutrophils cultured in medium alone. However, LPS-dependent TNF-alpha production was increased by exposure to SNP (p < 0.05); this effect was further increased by the addition of NAC (p < 0.02). IFN-gamma greatly increased LPS-mediated TNF-alpha production by human neutrophils (p < 0.01), and SNP plus NAC was found to further augment this production (p < 0.01). The up-regulation of TNF-alpha production by nitric oxide was not associated with increased amounts of LPS-induced TNF-alpha mRNA, and was not reproduced by exposing neutrophils to cGMP analogues. These data suggest that nitric oxide released by endothelial and vascular smooth muscle cells may exert a paracrine effect on human neutrophils and augment the inflammatory response in sepsis by increasing the production of cytokines. Although the mechanism of this effect remains unknown, it does not seem to be dependent on cGMP or increased levels of TNF-alpha mRNA.

Endmembers are represented via beta distributions, hereafter referred to as betas, to constrain endmembers to a physically-meaningful range. Two associated spectral unmixing algorithms are described and applied to simulated and real hyperspectral imagery.

Polyamines, Ornithine Decarboxylase, and Diamine Oxidase in the Substantia Nigra and Striatum of the Male Rat After Hemitransection (1988)

Partial hemitransection at the mesodiencephalic junction in the rat increased striatal and nigral putrescine concentrations on the lesioned side for at least 168 h, with maximal increases between 24 and 48 h. Spermidine and spermine levels declined at 24 h in the striatum, rising above control values at 48 h and further at 168 h. In the substantia nigra, they remained unchanged for the first 48 h and then increased by 168 h. Cadaverine in the striatum also increased at 48 h. On the intact side putrescine increased but to a much lesser extent (at 48 h in the striatum and at 24 and 48 h in the substantia nigra). Ornithine decarboxylase and diamine oxidase activities showed maximal increases at 24 h in the striatum of the lesioned side, whereas in the substantia nigra ornithine decarboxylase attained a very high value as early as 4 h after the operation and diamine oxidase activity peaked at 48 h. The enzyme activities returned toward the basal values at 168 h. On the intact side, ornithine decarboxylase showed a small increase starting at 4 h and diamine oxidase was enhanced at 48 h. These results indicate that the stimulation of biosynthetic and degradative enzymes of polyamine metabolism accompanied by marked and prolonged increases in putrescine may be essential events in the early phases of neuronal response to mechanical injury in the CNS.

2715 Research on micro pressure sensor implanted into gene alteration mouse (2006)

Many researches of the gene using the gene alteration mice have been performed. However, 600,000 kinds of mice are produced for the elucidation of gene function. For this reason, the microchip for individual discernment for discriminating and managing huge kind of mouse must be developed. In this research, the detailed structure and functions of the micro pressure sensor were investigated by the FEM analysis. About 144 kinds of sensors are made in consideration of an analytical result. A basic character of the pressure sensor to measure the ventricular rate with this device was clarified. Two kinds of micro pressure sensors the number of cardiac beats were actually mounted, and were measured. As a result of conducting evaluated experiments clear periodic signals was observed, and there were confirmed as cardiac also in beats by the power spectrum analysis.
Enzyme immunoassays for the detection of microbial antigens in body fluids: an overview (1985)

Abstract
An appearance based approach for video object extraction and representation (2003)

We describe a novel appearance based scheme for extraction and representation of video objects. The tracking algorithm used for video object extraction is based upon a new eigen-space update scheme. We propose a scheme for organisation of video objects in an appearance based hierarchy. The appearance based hierarchy is constructed using a new SVD based eigen-space merging algorithm. The hierarchy enables approximate query resolution. Experiments performed on a large number of video sequences have yielded promising results.
Receptor protein tyrosine phosphatase μ: measuring where to stick (2008)

We review here recent results on the structure and function of a receptor protein tyrosine phosphatase, RPTPmicro. In addition to their intercellular catalytic domains which bear the phosphatase activity, the RPTPs are cell-surface-receptor-type molecules and in many cases have large extracellular regions. What role can these extracellular regions play in function? For RPTPmicro, the extracellular region is known to mediate homophilic adhesion. Sequence analysis indicates that it comprises six domains: an N-terminal MAM (meprin/A5/micro), one immunoglobulin-like domain and four fibronectin type III (FN) repeats. We have determined the crystal structure of the entire extracellular region for RPTPmicro in the form of a functional adhesion dimer. The physical characteristics and dimensions of the adhesion dimer suggest a mechanism by which the location of this phosphatase can be influenced by cell-cell spacings.
Antimicrobial action of achacin is mediated by L‐amino acid oxidase activity (2002)

Achacin is an antibacterial glycoprotein purified from the mucus of the giant snail, Achatina fulica Férussac, as a humoral defense factor. We showed that achacin has L-amino acid oxidase activity and can generate cytotoxic H(2)O(2); however, the concentration of H(2)O(2) was not sufficient to kill bacteria. The antibacterial activity of achacin was inhibited by various H(2)O(2) scavengers. Immunochemical analysis revealed that achacin was preferentially bound to growth-phase bacteria, accounting for the important role in growth-phase-dependent antibacterial activity of achacin. Achacin may act as an important defense molecule against invading bacteria.
