Stochastic RUL Calculation Enhanced With TDNN-Based IGBT Failure Modeling

Power electronics are widely used in the transport and energy sectors. Hence, the reliability of these power electronic components is critical to reducing the maintenance cost of these assets. It is vital that the health of these components is monitored for increasing the safety and availability of a system. The aim of this paper is to develop a prognostic technique for estimating the remaining useful life (RUL) of power electronic components. There is a need for an efficient prognostic algorithm that is embeddable and able to support on-board real-time decision-making. A time delay neural network (TDNN) is used in the development of failure modes for an insulated gate bipolar transistor (IGBT). Initially, the time delay neural network is constructed from training IGBTs' ageing samples. A stochastic process is performed for the estimation results to compute the probability of the health state during the degradation process. The proposed TDNN fusion with a statistical approach benefits the probability distribution function by improving the accuracy of the results of the TDDN in RUL prediction. The RUL (i.e., mean and confidence bounds) is then calculated from the simulation of the estimated degradation states. The prognostic results are evaluated using root mean square error (RMSE) and relative accuracy (RA) prognostic evaluation metrics.
Static analysis and optimization of semantic web queries

Static analysis is a fundamental task in query optimization. In this article we study static analysis and optimization techniques for SPARQL, which is the standard language for querying Semantic Web data. Of particular interest for us is the optionality feature in SPARQL. It is crucial in Semantic Web data management, where data sources are inherently incomplete and the user is usually interested in partial answers to queries. This feature is one of the most complicated constructors in SPARQL and also the one that makes this language depart from classical query languages such as relational conjunctive queries. We focus on the class of well-designed SPARQL queries, which has been proposed in the literature as a fragment of the language with good properties regarding query evaluation. We first propose a tree representation for SPARQL queries, called pattern trees, which captures the class of well-designed SPARQL graph patterns. Among other results, we propose several rules that can be used to transform pattern trees into a simple normal form, and study equivalence and containment. We also study the evaluation and enumeration problems for this class of queries.
Eggshell structure, measurements, and quality-affecting factors in laying hens: a review

Eggshell quality is one of the most significant factors affecting poultry industry; it economically influences egg production and hatchability. Eggshell consists of shell membranes and the true shell that includes mammillary layer, palisade layer, and cuticle. Measurements of eggshell quality include eggshell weight, shell percentage, breaking strength, thickness, and density. Mainly eggshell thickness and strength are affected by the time of egg components passage through the shell gland (uterus), eggshell ultra-structure (deposition of major units), and micro-structure (crystals size and orientation). Shell quality is affected by several internal and external factors. Major factors determining the quality or structure of eggshell are oviposition time, age, genotype, and housing system. Eggshell quality can be improved through optimization of genotype, housing system, and mineral nutrition.
Relationship between resting ventilatory chemosensitivity and maximal oxygen uptake in moderate hypobaric hypoxia.

This study tested the hypothesis that the extent of the decrement in (.)Vo(2max) and the respiratory response seen during maximal exercise in moderate hypobaric hypoxia (H; simulated 2,500 m) is affected by the hypoxia ventilatory and hypercapnia ventilatory responses (HVR and HCVR, respectively). Twenty men (5 untrained subjects, 7 long distance runners, 8 middle distance runners) performed incremental exhaustive running tests in H and normobaric normoxia (N) condition. During the running test, (.)Vo(2), pulmonary ventilation (Ve) and arterial oxyhemoglobin saturation (Sa(O(2))) were measured, and in two ventilatory response tests performed during N, a rebreathing method was used to evaluate HVR and HCVR. Mean HVR and HCVR were 0.36 +/- 0.04 and 2.11 +/- 0.2 l.min(-1). mmHg(-1), respectively. HVR correlated significantly with the percent decrements in (.)Vo(2max) (%d(.)Vo(2max)), Sa(O(2)) [%dSa(O(2)) = (N-H). N(-1). 100], and (.)Ve/(.)Vo(2) seen during H condition. By contrast, HCVR did not correlate with any of the variables tested. The increment in maximal Ve between H and N significantly correlated with %d(.)Vo(2max). Our findings suggest that O(2) chemosensitivity plays a significant role in determining the level of exercise hyperventilation during moderate hypoxia; thus, a higher O(2) chemosensitivity was associated with a smaller drop in (.)Vo(2max) and Sa(O(2)) under those conditions.
A molecular and evolutionary study of the beta-globin gene family of the Australian marsupial Sminthopsis crassicaudata.

Beta-globin gene families in eutherians (placental mammals) consist of a set of four or more developmentally regulated genes which are closely linked and, in general, arranged in the order 5'-embryonic/fetal genes-adult genes-3'. This cluster of genes is proposed to have arisen by tandem duplication of ancestral beta-globin genes, with the first duplication occurring 200 to 155 MYBP just prior to a period in mammalian evolution when eutherians and marsupials diverged from a common ancestor. In this paper we trace the evolutionary history of the beta-globin gene family back to the origins of these mammals by molecular characterization of the beta-globin gene family of the Australian marsupial Sminthopsis crassicaudata. Using Southern and restriction analysis of total genomic DNA and bacteriophage clones of beta-like globin genes, we provide evidence that just two functional beta-like globin genes exist in this marsupial, including one embryonic-expressed gene (S.c-epsilon) and one adult-expressed gene (S.c-beta), linked in the order 5'-epsilon-beta-3'. The entire DNA sequence of the adult beta-globin gene is reported and shown to be orthologous to the adult beta-globin genes of the North American marsupial Didelphis virginiana and eutherian mammals. These results, together with results from a phylogenetic analysis of mammalian beta-like globin genes, confirm the hypothesis that a two-gene cluster, containing an embryonic- and an adult-expressed beta-like globin gene, existed in the most recent common ancester of marsupials and eutherians. Northern analysis of total RNA isolated from embryos and neonatals indicates that a switch from embryonic to adult gene expression occurs at the time of birth, coinciding with the transfer of the marsupial from a uterus to a pouch environment.
Percutaneous Left Atrial Appendage Transcatheter Occlusion to Prevent Stroke in High-Risk Patients With Atrial Fibrillation: Early Clinical Experience

Background—Thromboembolism due to atrial fibrillation (AF) is a frequent cause of stroke. More than 90% of thrombi in AF form in the left atrial appendage (LAA). Obliteration of the appendage may prevent embolic complications. Methods and Results—We evaluated the feasibility and safety of implanting a novel device for percutaneous left atrial appendage transcatheter occlusion (PLAATO). LAA occlusion using the PLAATO system was attempted in 15 patients with chronic AF at high risk for stroke, who are poor candidates for long-term warfarin therapy. The implant consists of a self-expanding nitinol cage covered with a polymeric membrane (ePTFE). The LAA was successfully occluded in 15/15 patients (100%). Angiography and transesophageal echocardiography (TEE) during the procedure showed that the device was well-seated in all patients and that there was no evidence of perforation, device embolization, or interference with surrounding structures. In 1 patient, the first procedure was complicated by a hemopericardium, which occurred during LAA access. A second attempt 30 days later was successful with no untoward sequela. No other complications occurred. At 1-month follow-up, chest fluoroscopy and TEE revealed continued stable implant position with smooth atrial-facing surface and no evidence of thrombus. Conclusions—Thus, transcatheter closure of the LAA is feasible in humans. This novel implant technology may be appropriate for patients with AF who are not suitable candidates for anticoagulation therapy. Further trials are needed to show the long-term safety and its efficacy in reducing stroke.
Image prior combination in super-resolution image reconstruction

In this paper a new combination of image priors is introduced and applied to Super Resolution (SR) image reconstruction. A sparse image prior based on the £1 norms of the horizontal and vertical first order differences is combined with a non-sparse SAR prior. Since, for a given observation model, each prior produces a different posterior distribution of the underlying High Resolution (HR) image, the use of variational posterior distribution approximation on each posterior will produce as many posterior approximations as priors we want to combine. A unique approximation is obtained here by finding the distribution on the HR image given the observations that minimize a linear convex combination of the Kullback-Leibler (KL) divergences associated with each posterior distribution. We find this distribution in closed form. The estimated HR images are compared with images provided by other SR reconstruction methods.
Mice Lacking Ataxin-1 Display Learning Deficits and Decreased Hippocampal Paired-Pulse Facilitation

Spinocerebellar ataxia type 1 (SCA1) is a neurodegenerative disorder characterized by ataxia, progressive motor deterioration, and loss of cerebellar Purkinje cells. To investigate SCA1 pathogenesis and to gain insight into the function of the SCA1 gene product ataxin-1, a novel protein without homology to previously described proteins, we generated mice with a targeted deletion in the murine Sca1 gene. Mice lacking ataxin-1 are viable, fertile, and do not show any evidence of ataxia or neurodegeneration. However, Sca1 null mice demonstrate decreased exploratory behavior, pronounced deficits in the spatial version of the Morris water maze test, and impaired performance on the rotating rod apparatus. Furthermore, neurophysiological studies performed in area CA1 of the hippocampus reveal decreased paired-pulse facilitation inSca1 null mice, whereas long-term and post-tetanic potentiations are normal. These findings demonstrate that SCA1 is not caused by loss of function of ataxin-1 and point to the possible role of ataxin-1 in learning and memory.

Privacy-CNH: A Framework to Detect Photo Privacy with Convolutional Neural Network using Hierarchical Features

Photo privacy is a very important problem in the digital age where photos are commonly shared on social networking sites and mobile devices. The main challenge in photo privacy detection is how to generate discriminant features to accurately detect privacy at risk photos. Existing photo privacy detection works, which rely on low-level vision features, are non-informative to the users regarding what privacy information is leaked from their photos. In this paper, we propose a new framework called Privacy-CNH that utilizes hierarchical features which include both object and convolutional features in a deep learning model to detect privacy at risk photos. The generation of object features enables our model to better inform the users about the reason why a photo has privacy risk. The combination of convolutional and object features provide a richer model to understand photo privacy from different aspects, thus improving photo privacy detection accuracy. Experimental results demonstrate that the proposed model outperforms the state-of-the-art work and the standard convolutional neural network (CNN) with low-level features on photo privacy detection tasks.
Adaptive resource allocation scheme based on call admission control and mobility prediction for multimedia services in wireless cellular networks

QoS guaranteed for multimedia services in next generation wireless cellular networks poses great challenges due to the limited bandwidth and user mobility. Therefore, the demand for effective management of the resources is immensely needed to enhance the network performance. In this paper, adaptive resource allocation scheme based call admission control (CAC) and mobility prediction for controlling the multimedia traffic in the network to enhance the previous schemes which are reduce the handoff call dropping probability (HCDP) through an adaptive multimedia schemes with more accurate mobility prediction. However, the new calls have not been able to take advantage of the adaptive scheme and thus new call blocking probability (NCBP) has not improved as much. Therefore, the proposed scheme is designed to take advantage of the adaptive resource allocation scheme with new and handoff calls rather than only handoff call in order to enhance the system utilization and the NCBP. The simulation results show the performance of proposed scheme outperforms the compared scheme in terms of NCBP and bandwidth utilization.
NITROGEN DETERMINATION BY A CONTINUOUS DIGESTION AND ANALYSIS SYSTEM

The analysis of nitrogen has been of great concern to various workers in the field of biology and chemistry, and a great deal of effort has been spent in the development of methods for it. Moreover, the analysis of nitrogen yields an indirect measure of the composition of such compounds as proteins. The classic analysis for nitrogen involves oxidation or reduction by digestive procedures. Such procedures are based on the original work of Johan Kjeldahl between 1883 and 1888. Kjeldahl employed in his initial investigations a digestive mixture of sulfuric and phosphoric acids to decompose many organic substances. ' Essentially, the Kjeldahl procedure involves oxidation of organic matter, giving rise to carbon dioxide and water when boiled with concentrated sulfuric acid, the latter then being reduced to sulfur dioxide. The nitrogen present is converted to ammonium sulfate unless it was initially present as azo or nitro derivatives. In this case it is first treated with a mixture of salicylic acid and sulfuric acid, and the nitrated derivative thus formed is reduced with thiosulfate to an amino derivative. After complete destruction of the organic matter, an excess of sodium hydroxide is added to the sulfuric acid, and the liberated ammonia is distilled into a measured volume of a standard acid. Titration of the excess or residual acid with a standard alkali, using a suitable indicator, permits quantitation of the nitrogen content. Nitrogen also can be analyzed in organic compounds by conversion to ammonia followed by hypobromite oxidation of the ammonia to nitrogen. The nitrogen evolved is measured in gaseous form2 or quantitated via a mass spectrome ter. Many digestion mixtures have been proposed for use with the classic Kjeldahl method, and a host of additive aids to oxidation, metal catalysts, and substances to raise the boiling point have been suggested and employed. Some of these mixtures have very specific applications, and others are simply the result of a specific scientist's opinion that his mixture afforded superior digestive efficiency. The essence of the mechanism remains the same, however, regardless of the digestive mixture. Essentially, the Kjeldahl procedure consists of the introduction of a sample into a suitable flask with an appropriate digestive solution, the prolonged boiling of the organic matter to oxidize the carbon and hydrogen with reduction of the sulfuric acid to sulfur dioxide, and the subsequent reduction of the nitrogenous matter to a m m ~ n i a . ~ This procedure is both tedious and cumbersome; moreover, additional manipulative operations must be carried out in order to arrive a t a quantitative answer. The stumbling block in automating the nitrogen analysis of organic compounds on the basis of the principles established by Kjeldahl was the digestive phase. I t was necessary to provide a means for continuous introduction and removal of the digestive mixture and intermittent or continuous introduction of the material to be digested. A suitable time lag had to be provided so that
Use of fluorescently labeled caspase inhibitors as affinity labels to detect activated caspases

Activation of caspases is the key event of apoptosis and different approaches were developed to assay it To detect their activation in situ, we applied fluorochrome labeled inhibitors of caspases (FLICA) as affinity labels of active centers of these enzymes. The FLlCA ligands are fluorescein or sulforhodamine conjugated peptide-fluoromethyl ketones that covalently bind to enzymatic centers of caspases with 1:l stoichiometry. The specificity of FLICA towards individual caspases is provided by the peptide sequence of amino acids. Exposure of live cells to FLICA results in uptake of these ligands and their binding to activated caspases; unbound FLICA is removed by cell rinse. Cells labeled with FLICA can be examined by fluorescence microscopy or subjected to quantitative analysis by cytometry. Intracellular binding sites of FLICA are consistent with known localization of caspases. Covalent binding of FLICA allowed us to identify the labeled proteins by immunoblotting: the proteins that bound individual FLICAs had molecular weight between 17 and 22 kDa, which corresponds to large subunits of the caspases. Detection of caspases activation by FLICA can be combined with other markers of apoptosis or cell cycle for multiparametric analysis. Because FLICA are caspase inhibitors they arrest the process of apoptosis preventing cell disintegration. The stathmo-apoptotic method was developed, therefore, that allows one to assay cumulative apoptotic index over long period of time and estimate the rate of cell entry into apoptosis for large cell populations. FLICA offers a rapid and convenient assay of caspases activation and can also be used to accurately estimate the incidence of apoptosis.
What Physiological Changes and Cerebral Traces Tell Us about Adhesion to Fiction During Theater-Watching?

Live theater is typically designed to alter the state of mind of the audience. Indeed, the perceptual inputs issuing from a live theatrical performance are intended to represent something else, and the actions, emphasized by the writing and staging, are the key prompting the adhesion of viewers to fiction, i.e., their belief that it is real. This phenomenon raises the issue of the cognitive processes governing access to a fictional reality during live theater and of their cerebral underpinnings. To get insight into the physiological substrates of adhesion we recreated the peculiar context of watching live drama in a functional magnetic resonance imaging (fMRI) experiment, with simultaneous recording of heart activity. The instants of adhesion were defined as the co-occurrence of theatrical events determined a priori by the stage director and the spectators’ offline reports of moments when fiction acted as reality. These data served to specify, for each spectator, individual fMRI time-series, used in a random-effect group analysis to define the pattern of brain response to theatrical events. The changes in this pattern related to subjects’ adhesion to fiction, were investigated using a region of interest analysis. The results showed that adhesion to theatrical events correlated with increased activity in the left BA47 and posterior superior temporal sulcus, together with a decrease in dynamic heart rate variability, leading us to discuss the hypothesis of subtle changes in the subjects’ state of awareness, enabling them to mentally dissociate physical and mental (drama-viewing) experiences, to account for the phenomenon of adhesion to dramatic fiction.
Individual performance calibration using physiological stress signals

The relation between performance and stress is described by the Yerkes-Dodson Law but varies significantly between individuals. This paper describes a method for determining the individual optimal performance as a function of physiological signals. The method is based on attention and reasoning tests of increasing complexity under monitoring of three physiological signals: Galvanic Skin Response (GSR), Heart Rate (HR), and Electromyogram (EMG). Based on the test results with 15 different individuals, we first show that two of the signals, GSR and HR, have enough discriminative power to distinguish between relax and stress periods. We then show a positive correlation between the complexity level of the tests and the GSR and HR signals, and we finally determine the optimal performance point as the signal level just before a performance decrease. We also discuss the differences among signals depending on the type of test.
