Range Imaging With Adaptive Color Structured Light

In range sensing with time-multiplexed structured light, there is a trade-off between accuracy, robustness and the acquisition period. In this paper a novel structured light method is described. Adaptation of the number and form of the projection patterns to the characteristics of the scene takes place as part of the acquisition process. Noise margins are matched to the actual noise level, thus reducing the number of projection patterns to the necessary minimum. Color is used for light plane labeling. The dimension of the pattern space are thus increased without raising the number of projection patterns. It is shown that the color of an impinging light plane can be identified from the image of the illuminated scene, even with colorful scenes. Identification is local and does not rely on spatial color sequences. The suggested approach has been implemented and the theoretical results are supported by experiments.
The Impact of Shift Work on Brazilian Train Drivers with Different Chronotypes: A Comparative Analysis through Objective and Subjective Criteria

Objective: The aim of this study was to compare sleep pattern, tiredness sensation and quality of life between different chronotypes in train drivers from a Brazilian transportation company. Subjects and Methods: Ninety-one train drivers, working a rotary work schedule including night shift, were divided into three groups according to their chronotype (morning types, intermediate or evening types) and were assessed for their sleep and quality of life, as characterized by a subjective questionnaire and the Psychomotor Vigilance Task (PVT), applied before and immediately after the night shift. The pattern of activity and rest was measured for 10 days by actigraphy, and the chronotype was determined through the Morningness-Eveningness Questionnaire. Results: Forty-one (45.1%) individuals were classified as morning type, 44 (48.4%) were classified as intermediate and 6 (6.6%) as evening type. The evening types had a tendency to remain awake for a longer period of time before the night shift (p = 0.05) and scored worse overall for quality of life compared to morning types (p = 0.11). There was no significant difference between the groups regarding variability in the PVT performance, even when covaried by the period of waking time before the test. There was no significant difference either in feelings of fatigue before and after starting the shift. Conclusion: Although the evening type number was small, evening type individuals scored worse relative to sleep and quality of life than morning type individuals.
The Design and Performance Study of Binary Transitive Closure Algorithms

Transitive closure operation is one of the most useful new operations in deductive database systems. When it is added to conventional relational database systems, most practical problems with recursion can be coped with. Therefore, efficient processing of transitive closure is an important task in deductive database systems. Transitive closure operation can be divided into total closure and query closure operations. To implement the operations, we can have unary or binary algorithms. A lot of work has been done on the efficient derivation of total closures and unary query closures, but not much work has been done on binary query closures. A binary query closure algorithm derives the transitive closure relevant to a set of query constants, associated with pairs of the initial query constants and their driven elements. The binary query closure operation is more frequently used than the unary one. In this research, 6 algorithms are developed for binary query transitive closure processing, namely Binary Wavefront, Unary Wavefront with Frontier-Edges, Unary Wavefront with Implied-Edges-Closure, Unary Wavefront Preprocessing with TotalFrontier-Edges, level-relaxed Binary Wavefront, and level-relaxed Unary Wavefront Preprocessing with Total-Frontier-Edges. These algorithms are analyzed and their relative performances are compared on their VO behavior and other processing costs. More importantly, the analysis is done on different characteristics of data and on different buffer sizes. Our analysis and performance study show that reference locality and data clustering play an important role in the performance of the algorithms. The ordering of the set of relational operations is also important in determining the 110 performance of the algorithms. Our research also demonstrates that the rate at which the disk VO of an algorithm decreases with the increase in buffer size is affected by the Maximum Buffer Requirement of the algorithm. Among the algorithms without level relaxation, Binary Wavefront outperforms the others in a wide range of data sets when the buffer size is small. Unary Wavefront Preprocessing with Total-Frontier-Edges Algorithm performs better when the number of query constants is small and the buffer size is large. A base relation that requires a lot of iterative processing and generates a large volume of answers to the transitive query is best processed by Unary Wavefront with Implied-Edges-Closure Algorithm. The analysis of the YO behavior of Unary Wavefront with Frontier-Edges Algorithm helps to develop a better algorithm, like the Unary Wavefront Preprocessing with Total-Frontier-Edges Algorithm. The level relaxed versions of the algorithms are best for clustered data. Our research provides insight into binary query closure processing. We hope that this will, in turn, stimulate further research on the processing of more complex recursions.
A new TSV set architecture for high reliability

Recently, 3D IC design is a very attracting issue, and the importance of system reliability increases. This paper proposes a new reliable and repairable TSV set architecture. The proposed architecture supports the previous TSV repair scheme using TSV redundancies and provides a defect/error detection function reutilizing residual TSV redundancies for high reliability of 3D ICs. This can be applied to both online test and soft error detection/analysis. The results show that the proposed TSV set architecture guarantees high TSV redundancy efficiency and reliability. And, the results show that the proposed TSV architecture achieves defect/error coverages which are steady and predictable by a simple formula.
Matter waves with orbital angular momentum: Collapse suppression and bistability

We explore the influence of the orbital angular momentum on the dynamics of vortex-free elliptic clouds of Bose-Einstein condensates with attractive interatomic interactions. We show that the number of atoms corresponding to the collapse threshold can be radically increased for such rotating nonlinear matter waves trapped in a radially symmetric harmonic potential. Moreover, rotating anisotropic traps can simultaneously support two differently aligned elliptical matter wave states stabilized against the collapse.
Is it Better to Average Probabilities or Quantiles?

We consider two ways to aggregate expert opinions using simple averages: averaging probabilities and averaging quantiles. We examine analytical properties of these forecasts and compare their ability to harness the wisdom of the crowd. In terms of location, the two average forecasts have the same mean. The average quantile forecast is always sharper: it has lower variance than the average probability forecast. Even when the average probability forecast is overconfident, the shape of the average quantile forecast still offers the possibility of a better forecast. Using probability forecasts for gross domestic product growth and inflation from the Survey of Professional Forecasters, we present evidence that both when the average probability forecast is overconfident and when it is underconfident, it is outperformed by the average quantile forecast. Our results show that averaging quantiles is a viable alternative and indicate some conditions under which it is likely to be more useful than averaging probabilities. This paper was accepted by Peter Wakker, decision analysis.
1 ELECTRODEPOSITION OF 2 COPPER / CARBONOUS NANOMATERIAL 3 COMPOSITE COATINGS FOR 4 HEAT-DISSIPATION MATERIALS 5

Carbonous nanomaterials are promising additives for composite coatings for 18 heat-dissipation materials because of their excellent thermal conductivity. Here, copper/carbonous 19 nanomaterial composite coatings were prepared using nanodiamond (ND) as the carbonous 20 nanomaterial. The copper/ND composite coatings were electrically deposited onto copper 21 substrates from a continuously stirred copper sulfate coating bath containing NDs. NDs were 22 dispersed by ultrasonic treatment, and the initial bath pH was adjusted by adding sodium 23 hydroxide solution or sulfuric acid solution before electrodeposition. The effects of various coating 24 conditions—the initial ND concentration, initial bath pH, stirring speed, electrical current density, 25 and the amount of electricity—on the ND content of the coatings were investigated. Furthermore, 26 the surface of the NDs was modified by hydrothermal treatment to improve ND incorporation. A 27 higher initial ND concentration and a higher stirring speed increased the ND content of the 28 coatings, whereas a higher initial bath pH and a greater amount of electricity decreased it. The 29 electrical current density showed a minimum ND content at approximately 5 A/dm2. 30 Hydrothermal treatment, which introduced carboxyl groups onto the ND surface, improved the 31 ND content of the coatings. A copper/ND composite coating with a maximum of 3.85 mass% ND 32 was obtained. 33
“Fast-track”-Rehabilitation in Surgery, a Multimodal Concept

Abstract The rates of postoperative local surgical complications (e.g. wound-infection, abscess, anastomotic leakage) and the postoperative mortality have markedly decreased over the past decades. However the occurrence of general medical complications (e.g. cardio-pulmonary or renal dysfunction, nosocomial infections, thromboembolism) after abdominal surgery is still frequent with an incidence of 20–60% (1–6). “Fast-track”-surgery, also called “Fast-track”-rehabilitation or “ERAS” (enhanced recovery after surgery) programme, is a combination of different pre-and intraoperative measures, which have been mainly validated in elective colonic surgery, but they can be principally employed in all surgical settings. With this approach it is possible to accelerate the postoperative convalescence and reduce the rate of general complications markedly (4, 7–10).

CD11b/CD18 Acts in Concert with CD14 and Toll-Like Receptor (TLR) 4 to Elicit Full Lipopolysaccharide and Taxol-Inducible Gene Expression1 2 3

Overproduction of inflammatory mediators by macrophages in response to Gram-negative LPS has been implicated in septic shock. Recent reports indicate that three membrane-associated proteins, CD14, CD11b/CD18, and Toll-like receptor (TLR) 4, may serve as LPS recognition and/or signaling receptors in murine macrophages. Therefore, the relative contribution of these proteins in the induction of cyclooxygenase 2 (COX-2), IL-12 p35, IL-12 p40, TNF-α, IFN-inducible protein (IP)-10, and IFN consensus sequence binding protein (ICSBP) genes in response to LPS or the LPS-mimetic, Taxol, was examined using macrophages derived from mice deficient for these membrane-associated proteins. The panel of genes selected reflects diverse macrophage effector functions that contribute to the pathogenesis of septic shock. Induction of the entire panel of genes in response to low concentrations of LPS or Taxol requires the participation of both CD14 and TLR4, whereas high concentrations of LPS or Taxol elicit the expression of a subset of LPS-inducible genes in the absence of CD14. In contrast, for optimal induction of COX-2, IL-12 p35, and IL-12 p40 genes by low concentrations of LPS or by all concentrations of Taxol, CD11b/CD18 was also required. Mitigated induction of COX-2, IL-12 p35, and IL-12 p40 gene expression by CD11b/CD18-deficient macrophages correlated with a marked inhibition of NF-κB nuclear translocation and mitogen-activated protein kinase (MAPK) activation in response to Taxol and of NF-κB nuclear translocation in response to LPS. These findings suggest that for expression of a full repertoire of LPS-/Taxol-inducible genes, CD14, TLR4, and CD11b/CD18 must be coordinately engaged to deliver optimal signaling to the macrophage.
Thick airfoil designs for the root of the 10MW INNWIND.EU wind turbine

The main objective of the “INNWIND.EU” project is to investigate and demonstrate innovative designs for 10-20MW offshore wind turbines and their key components, such as lightweight rotors. In this context, the present paper describes the development of two new airfoils for the blade root region. From the structural point of view, the root is the region in charge of transmitting all the loads of the blade to the hub. Thus, it is very important to include airfoils with adequate structural properties in this region. The present article makes use of high-thickness and blunt trailing edge airfoils to improve the structural characteristics of the airfoils used to build this blade region. CENER's (National Renewable Energy Center of Spain) airfoil design tool uses the airfoil software XFOIL to compute the aerodynamic characteristics of the designed airfoils. That software is based on panel methods which show some problems with the calculation of airfoils with thickness bigger than 35% and with blunt trailing edge. This drawback has been overcome with the development of an empirical correction for XFOIL lift and drag prediction based on airfoil experiments. From the aerodynamic point of view, thick airfoils are known to be very sensitive to surface contamination or turbulent inflow conditions. Consequently, the design optimization takes into account the aerodynamic torque in both clean and contaminated conditions. Two airfoils have been designed aiming to improve the structural and the aerodynamic behaviour of the blade in clean and contaminated conditions. This improvement has been corroborated with Blade Element Momentum (BEM) computations.

CD8+ T Cells but Not Polymorphonuclear Leukocytes Are Required To Limit Chronic Oral Carriage of Candida albicans in Transgenic Mice Expressing Human Immunodeficiency Virus Type 1

ABSTRACT Candida albicans causes oropharyngeal candidiasis (OPC) but rarely disseminates to deep organs in human immunodeficiency virus (HIV) infection. Here, we used a model of OPC in CD4C/HIVMut transgenic (Tg) mice to investigate the role of polymorphonuclear leukocytes (PMNs) and CD8+ T cells in limiting candidiasis to the mucosa. Numbers of circulating PMNs and their oxidative burst were both augmented in CD4C/HIVMutA Tg mice expressing rev, env, and nef of HIV type 1 (HIV-1), while phagocytosis and killing of C. albicans were largely unimpaired compared to those in non-Tg mice. Depletion of PMNs in these Tg mice did not alter oral or gastrointestinal burdens of C. albicans or cause systemic dissemination. However, oral burdens of C. albicans were increased in CD4C/HIVMutG Tg mice expressing only the nef gene of HIV-1 and bred on a CD8 gene-deficient background (CD8−/−), compared to control or heterozygous CD8+/− CD4C/HIVMutG Tg mice. Thus, CD8+ T cells contribute to the host defense against oral candidiasis in vivo, specifically in the context of nef expression in a subset of immune cells.
On learning feedforward neural networks with noise injection into inputs

Injecting noise to the inputs during the training of feedforward neural networks (FNN) can improve their generalization performance remarkably. Reported works justify this fact arguing that noise injection is equivalent to a smoothing regularization with the input noise variance playing the role of the regularization parameter. The success of this approach depends on the appropriate choice of the input noise variance. However, it is often not known a priori if the degree of smoothness imposed on the FNN mapping is consistent with the unknown function to be approximated. In order to have a better control over this smoothing effect, a cost function putting in balance the smoothed fitting induced by the noise injection and the precision of approximation, is proposed. The second term, which aims at penalizing the undesirable effect of input noise injection or controlling the deviation of the random perturbed cost, was obtained by expressing a certain distance between the original cost function and its random perturbed version. In fact, this term can be derived in general for parametrical. models that satisfy the Lipschitz property. An example is included to illustrate the effectiveness of learning with this proposed cost function when noise injection is used.
Crystal structures of human PAICS reveal substrate and product binding of an emerging cancer target

The bifunctional human enzyme phosphoribosylaminoimidazole carboxylase and phosphoribosylaminoimidazolesuccinocarboxamide synthetase (PAICS) catalyzes two essential steps in the de novo purine biosynthesis pathway. PAICS is overexpressed in many cancers and could be a promising target for the development of cancer therapeutics. Here, using gene knockdowns and clonogenic survival and cell viability assays, we demonstrate that PAICS is required for growth and survival of prostate cancer cells. PAICS catalyzes the carboxylation of aminoimidazole ribonucleotide (AIR) and the subsequent conversion of carboxyaminoimidazole ribonucleotide (CAIR) and l-aspartate to N-succinylcarboxamide-5-aminoimidazole ribonucleotide (SAICAR). Of note, we present the first structures of human octameric PAICS in complexes with native ligands. In particular, we report the structure of PAICS with CAIR bound in the active sites of both domains and SAICAR bound in one of the SAICAR synthetase domains. Moreover, we report the PAICS structure with SAICAR and an ATP analog occupying the SAICAR synthetase active site. These structures provide insight into substrate and product binding and the architecture of the active sites, disclosing important structural information for rational design of PAICS inhibitors as potential anticancer drugs.
A Survey of Distributed Optimization and Control Algorithms for Electric Power Systems

Historically, centrally computed algorithms have been the primary means of power system optimization and control. With increasing penetrations of distributed energy resources requiring optimization and control of power systems with many controllable devices, distributed algorithms have been the subject of significant research interest. This paper surveys the literature of distributed algorithms with applications to optimization and control of power systems. In particular, this paper reviews distributed algorithms for offline solution of optimal power flow (OPF) problems as well as online algorithms for real-time solution of OPF, optimal frequency control, optimal voltage control, and optimal wide-area control problems.
An inherited mitochondrial DNA disruptive mutation shifts to homoplasmy in oncocytic tumor cells

A disruptive frameshift mtDNA mutation affecting the ND5 subunit of complex I is present in homoplasmy in a nasopharyngeal oncocytic tumor and inherited as a heteroplasmic germline mutation recurring in two of the patient's siblings. Homoplasmic ND5 mutation in the tumor correlates with lack of the ND6 subunit, suggesting complex I disassembly. A few oncocytic areas, expressing ND6 and heteroplasmic for the ND5 mutation, harbor a de novo homoplasmic ND1 mutation. Since shift to homoplasmy of ND1 and ND5 mutations occurs exclusively in tumor cells, we conclude that complex I mutations may have a selective advantage and accompany oncocytic transformation.

Chromatin Interaction Analysis Using Paired‐End Tag Sequencing

Chromatin Interaction Analysis using Paired‐End Tag sequencing (ChIA‐PET) is a technique developed for large‐scale, de novo analysis of higher‐order chromatin structures. Cells are treated with formaldehyde to cross‐link chromatin interactions, DNA segments bound by protein factors are enriched by chromatin immunoprecipitation, and interacting DNA fragments are then captured by proximity ligation. The Paired‐End Tag (PET) strategy is applied to the construction of ChIA‐PET libraries, which are sequenced by high‐throughput next‐generation sequencing technologies. Finally, raw PET sequences are subjected to bioinformatics analysis, resulting in a genome‐wide map of binding sites and chromatin interactions mediated by the protein factor under study. This unit describes ChIA‐PET for genome‐wide analysis of chromatin interactions in mammalian cells, with the application of Roche/454 and Illumina sequencing technologies. Curr. Protoc. Mol.

A CUTE N ECROTIZING P ANCREATITIS

CUTE pancreatitis may be clinically mild or severe. Severe acute pancreatitis is usually a result of pancreatic glandular necrosis. The morbidity and mortality associated with acute pancreatitis are substantially higher when necrosis is present, especially when the area of necrosis is also infected. 1 It is important to identify patients with pancreatic necrosis so that appropriate management can be undertaken. In recent years, the treatment of these patients has shifted away from early surgical debridement (“necrosectomy”) to aggressive intensive medical care, with specific criteria for operative and nonoperative intervention. 2,3 Advances in radiologic imaging and aggressive medical management with emphasis on the prevention of infection have allowed prompt identification of complications and improvement in outcome for these patients. 4 This article reviews recent advances in the diagnosis and treatment of acute necrotizing pancreatitis.
