A stochastic failure compensation controller of induction motor based state estimation technique

The purpose of this paper deals with the stochastic failure compensation controller of induction motor based state estimation technique. It is well known that induction motor drives are widely used as important parts in industrial applications. In consequence it must be carefully controlled to ensure optimum, profitable and reliable operations. However induction motor drive systems are also known as complex non-linear time-varying systems. Based on the fact that the system model can be significantly simplified if one applies in addition with the d-q Park transformation an appropriate field orientation technique, an adequate model structure of the induction motor is obtained. The observer-based state variable estimation technique, stochastic and determinist, is used for control and monitoring of the considered induction motor system. Finally a simulation example of is given to point out the merits of the proposed approach for stochastic optimal compensation and control for induction motor.
Impact of Ticagrelor vs. Clopidogrel in Patients With Acute Coronary Syndrome Undergoing Percutaneous Coronary Intervention After Risk Stratification With the CHA2DS2-VASc Score

Backgrounds The clinical benefit of ticagrelor vs. clopidogrel in unselected patients with acute coronary syndrome (ACS) after percutaneous coronary intervention (PCI) remains controversial in the real world. This study was aimed to investigate the impact of ticagrelor vs. clopidogrel in subjects with ACS without atrial fibrillation or flutter (AF) after PCI based on risk stratification using the CHA2DS2-VASc score. Methods In 2016–2019, patients who underwent PCI with at least one stent implanted in the General Hospital of Northern Theater Command were classified as low- or high-risk groups according to the CHA2DS2-VASc score. Incidences of 12-month ischemia [cardiac death, myocardial infarction (MI), or stroke], all-cause death, Bleeding Academic Research Consortium (BARC) 2,3,5 bleeding, BARC 3,5 bleeding, and net adverse clinical events (NACEs) (all-cause death, MI, stroke, or BARC 3, 5 bleeding) with aspirin plus different P2Y12 inhibitors (clopidogrel or ticagrelor) were appraised among different risk groups. Propensity score matching (PSM) and Cox multivariate analysis were used to balance the groups. Results A total of consecutive 17,037 patients with ACS were enrolled. The optimal cut-off value of the CHA2DS2-VASc score for ischemic events by the Youden test was 3 points. Among patients with high risk (CHA2DS2-VASc ≥ 3, n = 6,151), ticagrelor was associated with slightly lower risks of ischemic events (2.29% vs. 3.54%, P = 0.02) and stroke (0.39% vs. 1.08%, P = 0.01) without excessive risk of BARC 3, 5 bleeding events (2.16% vs. 2.11%, P = 0.92) compared to clopidogrel within 12 months after PCI. For patients with low risk (CHA2DS2-VASc < 3, n = 10,886), a statistically significant difference was seen in the incidence of overall 12-month BARC 2, 3, 5 bleeding events by P2Y12 receptor inhibitor (4.00% vs. 3.26%) with a similar incidence of the ischemic events (1.40% vs. 1.52%). Results in the PSM cohort and the adjustment with Cox multivariate analysis were consistent with the main outcomes. Conclusion Higher CHA2DS2-VASc scores were associated with a higher incidence of 1-year ischemic events for the patients with ACS after PCI. Compared with clopidogrel, ticagrelor was associated with lower ischemic events within 12 months after PCI without excessive risk of bleeding in high-risk patients but shows poor safety with excess bleeding in low-risk patients.
Energy Efficiency in Datacenters through Virtualization: A Case Study

Data centers have turned into a big concern for enterprises. Data centers have exhibited steadyenergy demand growth, and electric utilities have received sizeable requests for electrical power for new facilities. Electricity usage costs have become an increasing fraction of the total cost of ownership for data centers. There are many challenges and opportunities for researchers to explore the issues to quantify the electricity savings and provide methods for improving the energy efficiency. This paper systematically explores the opportunities and adoptable methods for achieving the energy efficiency in datacenters. We have presented a Study on Data Center Virtualization and scaled it to realize significant savings
The Effect of a New Oral Hygiene Training Program On Approximal Caries in 12-15-Year-Old Brazilian Children: Results After Three Years

This study evaluated the effects of a new oral hygiene training program on approximal caries in a population of 12-13-year-old Brazilian schoolchildren with a well-established habit of daily toothbrushing with a F dentifrice. Two hundred twenty-two children were randomly allocated into two test groups (I and II) and one control group (III). Group I subjects were trained to establish needs-related oral hygiene habits based on self-diagnosis and a new behavioral principle, the 'linking method', for establishment of habits. The first three visits (20 minutes each) were scheduled at two-day intervals. They were recalled for a monthly check-up during the first 4 months, and then every 3 months for re-evaluation of the results based on self-diagnosis. Group II subjects were recalled at the same intervals for detailed oral hygiene instruction on how to clean every tooth surface using dental tape, toothbrush, and fluoride dentifrice. Group I developed significantly fewer (p <0.001) new approximal manifest (dentin) caries lesions than groups II and III. The mean values (SEM) were 2.3(0.29), 4.7(0.59), and 5.3(0.68), respectively. The conclusions from our study are: In a toothbrushing population using fluoride dentifrices and fluoridated drinking water, the oral hygiene training program with behavioral modification significantly reducedcaries incidence on approximal surfaces. Frequentrepetition of training in meticulous oral hygiene is almost redundant.
Assay of poliomyelitis neutralizing antibody in disposable plastic panels.

A method for titration of poliomyelitis neutralizing antibodies in disposable plastic panels is described. This method is a modification of those reported from the laboratories of Salk and of McLean, in which antibody is measured by protection of monkey-kidney cell suspensions from the metabolic inhibitory influence of the polioviruses.White polystyrene panels, inexpensive and commercially available, are sterilized by alcohol or ultraviolet light. Only 20,000 to 30,000 passage cells are used per cup. The cell suspension is obtained by treatment of primary kidney cultures with a chelating agent, Versene. Such passage cells have a more uniform metabolic activity than trypsinized cells obtained directly from monkey kidney. Cell suspensions may be stored in the refrigerator for up to three weeks and still prove useful for the colour test. They are standardized for each test by a prior titration of their viability, the results of which are available in less than 24 hours. Both for the primary outgrowth from trypsinized monkey kidney and for the colour test itself, the simple lactalbumin hydrolysate medium is used. Panels are sealed with a paraffin oil of high viscosity.
Space charge distribution in filled epoxy composites containing micro and nano fillers

Epoxies represent a good host polymer matrix for addition of fillers to create composite systems. By adding fillers or additives during the solution phase it is possible to easily create a composite system with a relatively high state of dispersion. Since epoxies represent good dielectric materials, much interest has been shown in the electrical charge characterization of such materials. This investigation studies the effect of addition of micro/Nano silicon dioxide and boron nitride to an epoxy matrix with respect to charge accumulation and transport. Data was collected using a PEA system on unfilled and filled systems with analysis and discussion on the effects that the fillers were having.
Ornithine Is a Novel Amino Acid and a Marker of Arginine Damage by Oxoaldehydes in Senescent Proteins

Abstract: Long‐lived proteins undergo age‐related postsynthetic modifications by glycation and advanced glycation end products (AGEs), which destabilize them by altering their conformation and charge. It was accidentally discovered that ornithine (orn) increased with age in acid hydrolyzates of human skin collagen and lens crystallins which led us to investigate the source of orn. Here, we detected such modifications of orn in these proteins. Acid hydrolysis of arginine (arg)‐base AGE standards produced orn at different yields. The data provide unequivocal evidence for the in vivo formation of orn and its own AGEs in aging proteins, and suggest that arg‐based AGEs serve as precursors of orn.
Applications of Testability Analysis: From ATPG to Critical Delay Path Tracing

This contribution outlines the applications of a recently proposed testability analysis algorithm that has been implemented as a controllability/ observability program named COP. Several benchmark modules, some approaching the complexity of VLSI, established that CPU cost grows only linearly with the size of the modules in all of the applications considered to date. These include effective heuristics for automatic test pattern generation (ATPG), assessment of random pattern testability, effective approach to approximate fault simulation. structural partitioning into cones, critical delay path tracing and characterization of the module in terms of a "testability signature". In view of the increasing complexity of VLSI, such performance provides strong motivation that the calibration of testability analysis be enhanced and its role further expanded.
On the Analysis of k-Secure t-Conference Key Distribution Scheme

The k-Secure t-Conference key distribution scheme (kStC-KDS) provides dynamic conferences in wireless sensor networks, which any group of t sensor nodes can derive a conference key using only its pre-distributed piece in sensor nod concept is based on a t-variate symmetric polynomial of degree k. However, the storage size of each sensor node is exponentially proportional to the size of group. Recently, Harn and Hsu used the multiplication of t onevariate polynomials of degree k instead to reduce the storage size, but the dealer should prepare various (t-1) polynomials of degree k for each sensor node. It is observed that we only need to store the polynomial terms with various coefficients for this t-variate k-degree symmetric polynomial in Blundo and De Santis's kStCKDS. Although the number of polynomial terms with various coefficients is known from the multiset concept. In this work, we adopt partition problem to precisely determine all polynomial terms, such that we can figure out which polynomial terms should be stored in each sensor node to reduce storage size.
Should we measure body temperature for patients who have recently undergone surgery?

Vermeulen et al. [1] have conducted a study of postoperative temperature measurements, and once again it has been found that such measurements are of very little use for detecting postoperative infections or treating patients who have had recent surgery. Although this topic has been examined at least 30 times previously in the literature [1, 2], the authors have added prospective data collection and a unique blinding technique to their study. In this study, the clinical team caring for the patients was not informed of patient body temperatures and was forced to make clinical decisions without consulting temperature data. In addition, the nurses and patients were not informed of patient temperatures. Patients underwent regular temperature measurement until the time of hospital discharge or for 14 days after surgery and were observed for any indication of infection, as defined according to Centers for Disease Control and Prevention criteria.
Small Peptide Analogue of SDF‐1α Supports Survival of Cord Blood CD34+ Cells in Synergy with Other Cytokines and Enhances Their Ex Vivo Expansion and Engraftment into Nonobese Diabetic/Severe Combined Immunodeficient Mice

The SDF‐1/CXCR4 axis has been implicated in the chemotaxis, homing, mobilization, and expansion of hematopoietic stem and progenitor cells. We studied the effects of a SDF‐1 peptide analogue CTCE‐0214 on the survival of cord blood CD34+ cells in culture, expansion, and engraftment of expanded cells in the nonobese diabetic/severe combined immunodeficient (NOD/SCID) mouse model. Our results demonstrated that CTCE‐0214 synergized with thrombopoietin (TPO), stem cell factor (SCF), or flt‐3 ligand (FL) on the survival of stem and progenitor cells in culture. Adding CTCE‐0214 at a low concentration (0.01 ng/ml) for 4 days together with TPO, SCF, and FL significantly enhanced ex vivo expansion of CD34+ cells to subsets of primitive (CD34+CD38− cells, colony‐forming unit‐mixed [CFU‐GEMMs]), erythroid (CFU‐Es), myeloid (CFU‐GMs), and megakaryocytic (CD61+CD41+ cells, CFU‐MKs) progenitors, as well as their multilineage engraftment in NOD/SCID mice. Interestingly, the short exposure of expanded cells to CTCE‐0214 (100 and 500 ng/ml) for 4 hours did not increase the quantity of progenitor cells but enhanced their engraftment capacity. The proportion of CD34+ cells expressing surface CXCR4 was decreased, but the overall number of this population increased upon expansion. The small peptide analogue of SDF‐1 could be developed for ex vivo expansion and improving engraftment of cord blood transplantation.
Proactive Sensitizing Effects of Acute Stress on Acoustic Startle Responses and Experimentally Induced Colitis in Rats: Relationship to Corticosterone

In humans, some individuals develop a syndrome after trauma (post-traumatic stress disorder, PTSD) characterized by increased startle responses and lower than normal cortisol secretion. We explored a rat model using the acoustic startle response (ASR) as a behavioral indicator of the effect of a short series of shocks. Because gastrointestinal disorders have been associated with prior stress, we also studied the rats' vulnerability to a chemically-induced colitis. After initial blood sampling, 12 rats were exposed to ten 1 mA 5 s foot-shocks while 12 rats served as controls. Nineteen days later the rats were tested for ASR. Thirty trials (10 trials at each of 95, 105, and 115 dB, pseudo-randomized) were given. After exposure for 6 days to dextran sulphate sodium in their drinking water, the rats were killed and the colons examined for erosions. Shocked rats showed greater startle responses and more colonic erosion than unshocked rats, but the shock effects were significant only for animals with low initial plasma corticosterone levels. Shocked rats also showed higher levels of granulocyte marker protein (GMP) in their faeces. These results suggest that low corticosterone secretion may represent a marker for vulnerability to long term effects of shocks as indicated by increased startle responses and colonic pathology.
Adenylate cyclase is required for chemotaxis to phosphotransferase system sugars by Escherichia coli

We report that in Escherichia coli, chemotaxis to sugars transported by the phosphotransferase system is mediated by adenylate cyclase, the nucleotide cyclase linked to the phosphotransferase system. We conclude that adenylate cyclase is required in this chemotaxis pathway because mutations in the cyclase gene (cya) eliminate or impair the response to phosphotransferase system sugars, even though other components of the phosphotransferase system known to be required for the detection of these sugars are relatively unaffected by such mutations. Moreover, merely supplying the mutant bacteria with the products of this enzyme, cyclic AMP and cyclic GMP, does not restore the chemotactic response. Because a residual chemotactic response is observed in certain strains with residual cyclic GMP synthesis but no cyclic AMP synthesis, it appears that the guanylate cyclase activity rather than the adenylate cyclase activity of the enzyme may be required for chemotaxis to sugars transported by the phosphotransferase system. Mutations in the cyclic nucleotide phosphodiesterase gene, which increase the level of both cyclic AMP and cyclic GMP, also reduce chemotaxis to these sugars. Therefore, it appears that control of the level of a cyclic nucleotide is critical for the chemotactic response to phosphotransferase system sugars.
Early Detection of Disease-Viral Hepatitis Type-C Using Elman Artificial Neural Network

The problem of founding important information in complex medical images which are needed in diagnosing of diseases with the complex data considered as one of the predication problem these days, so it is necessary to find aided means for diagnosing process. Artificial neural network (ANN) is one of them. This paper deals with the designing and implementation a classification ANN module for Lever Hepatitis(class-C) or type-C which doesn’t have any vaccine these days. The different in diagnosing between hepatitis and other liver diseases is often difficult on purely clinical grounds in addition the damage to the liver causes changes in the pattern of the serum enzymes and in recent years this has led to develop disease testing and its vaccine. Elman neural networks (NN) have been applied for automated detection of various medical diseases. Like its application on blood sample tests extracted from on line microscope (like it used in this research). That feature selection is an important issue by removing features that do not encode important data information from the images used.This helps physicians to extract features which aided them in diagnosing process. Kernal principle component analysis (PCA) is used to represent blood images as eigen-feature s of training images in addition to extract mathematical module for classification of it. Finally a neural network (NN) is trained to perform the typical images and classify them (diagnosing process). The produced NN system produces used a matlab package in order to design and diagnose the proposed module. The object of this system used in our work is to diagnosing lever Hepatitis type-C in samples of blood images wherever difficulties in practical experiments by finding an optimal feature from specialists whom work in laboratories.
The effect of increase in dielectric values on specific absorption rate (SAR) in eye and head tissues following 900, 1800 and 2450 MHz radio frequency (RF) exposure

Numerous studies have attempted to address the question of the RF energy absorption difference between children and adults using computational methods. They have assumed the same dielectric parameters for child and adult head models in SAR calculations. This has been criticized by many researchers who have stated that child organs are not fully developed, their anatomy is different and also their tissue composition is slightly different with higher water content. Higher water content would affect dielectric values, which in turn would have an effect on RF energy absorption. The objective of this study was to investigate possible variation in specific absorption rate (SAR) in the head region of children and adults by applying the finite-difference time-domain (FDTD) method and using anatomically correct child and adult head models. In the calculations, the conductivity and permittivity of all tissues were increased from 5 to 20% but using otherwise the same exposure conditions. A half-wave dipole antenna was used as an exposure source to minimize the uncertainties of the positioning of a real mobile device and making the simulations easily replicable. Common mobile telephony frequencies of 900, 1800 and 2450 MHz were used in this study. The exposures of ear and eye regions were investigated. The SARs of models with increased dielectric values were compared to the SARs of the models where dielectric values were unchanged. The analyses suggest that increasing the value of dielectric parameters does not necessarily mean that volume-averaged SAR would increase. Under many exposure conditions, specifically at higher frequencies in eye exposure, volume-averaged SAR decreases. An increase of up to 20% in dielectric conductivity or both conductivity and permittivity always caused a SAR variation of less than 20%, usually about 5%, when it was averaged over 1, 5 or 10 g of cubic mass for all models. The thickness and composition of different tissue layers in the exposed regions within the human head play a more significant role in SAR variation compared to the variations (5–20%) of the tissue dielectric parameters.
Decisional Balance among Potential Implantable Cardioverter Defibrillator Recipients: Development of the ICD‐Decision Analysis Scale (ICD‐DAS)

Sudden cardiac death is a well‐documented public health problem and the implantable cardioverter defibrillator (ICD) has demonstrated benefit in reducing mortality. Prospective patients must identify and evaluate the ICD's pros and cons and produce a personal decision. The purpose of this study was to create and evaluate a measure of patient‐evaluated pros and cons of the ICD, and its relationship to patient decision regarding ICD implantation.
Glucose metabolism alterations in Friedreich's ataxia

We have characterized the abnormalities of glucose metabolism associated with Friedreich's ataxia (FA) by studying plasma glucose, insulin, growth hormone (GH), and glucagon before and after an oral glucose tolerance test (OGTT), an IV glucose load, and an IV arginine load, in 21 patients and in controls. Twelve patients were normotolerant (NT) to glucose, five glucose-intolerant (IT), and four diabetic (DM). Insulin secretion of IT patients was increased and delayed during OGTT. Interestingly, the insulin release during arginine load was significantly decreased in NT and IT as well as in DM patients. The GH response to OGTT was altered in IT patients. Plasma glucagon after an arginine load was significantly higher in patients than in controls. The results indicate that FA is associated with insulin resistance, α-cell deficiency, and type I diabetes. These alterations might be genetically linked or metabolically related to the primary defect in FA. Their interplay or independent effects are responsible for abnormalities of glucose metabolism in FA.
Aminoglycoside resistance in Gram-negative blood isolates from various hospitals in Belgium and the Grand Duchy of Luxembourg. Aminoglycoside Resistance Study Group.

A total of 1102 consecutive clinical blood isolates, including 897 Enterobacteriaceae and 205 non-fermenting bacilli, were obtained from 13 university and university-affiliated hospitals, which were divided into a Northern and a Southern group. Resistance to gentamicin, tobramycin, netilmicin, amikacin and isepamicin was determined using a microdilution technique according to NCCLS procedures. The overall mean resistance level was 5.9% for gentamicin, 7.7% for tobramycin, 7.5% for netilmicin, 2.8% for amikacin and 1.2% for isepamicin. Resistance to amikacin and isepamicin was significantly higher in the Northern hospitals than in the Southern hospitals. In total, 157 isolates were found not to be susceptible to aminoglycosides. By PCR, 179 aminoglycoside resistance mechanisms, i.e. 150 genes encoding modifying enzymes and 29 permeability mechanisms, were detected in 148 isolates. A resistance mechanism could not be detected in nine isolates. Moreover, in a further 14 isolates the resistance profile was not fully explained by the detected genes. The aac(6')-I genes were found to be the most predominant resistance mechanism in both the Northern and Southern isolates, followed by aac(3) genes and permeability resistance. A total of 29 non-susceptible isolates harboured a combination of genes, 72.4% of which were a combination with the aac(6')-lb gene. The majority of these combinations were broad-spectrum combinations which represented 9.0% of the resistance mechanisms in non-susceptible Enterobacteriaceae and 19.3% in the non-fermenting bacilli.
