Ranking efficient DMUs by bootstrapping method

In this paper a method for ranking efficient Decision Making Units (DMUs) using Bootstrap has been introduced. The main drawback in existing method is that, DMU which is efficient but is not extreme efficient can not be ranked. The method proposed here is able to rank all kinds of efficient DMUs. The method is used in ranking efficient high schools.
New Approach to Partitioning Confidential Resources in Hybrid Clouds

Today, companies use more cloud environments such as hybrid clouds. Indeed, hybrid clouds give the opportunity to better manage resources mostly when companies have no space to store more resources in their private clouds. The best solution here is to allocate the required space in public cloud at a low cost. But how can resources be partitioned in hybrid clouds while assuring confidentiality of resources moved to public cloud. Many works have been done in this context. They suppose that confidentiality is assured by using encryption methods. But with this solution the cloud provider can access the resources stored on the cloud, which weakens the confidentiality of these. This work proposes an approach to the Confidential Resources Partitioning Problem in Hybrid Clouds (CRPHC) which aims at ensuring the confidentiality of resources by grouping as much as possible the most confidential resources in private cloud and resources with low degrees of confidentiality in public cloud while minimizing the size of resources to host in public cloud and consequently reducing the storage cost. This solution allows the possibility of using non-performing encryption methods which have a reduced treatement cost compared to efficient methods. Experimentally, our solution will be evaluated and compared to optimal solution given by CPLEX.
Microwave Imaging Within the First-Order Born Approximation by Means of the Contrast-Field Bayesian Compressive Sensing

A new approach based the contrast field (CF) formulation of the microwave imaging problem that exploits the Bayesian compressive sampling (BCS) paradigm is proposed for the reconstruction of sparse distributions of weak scatterers. Towards this end, the original inverse scattering problem is recast to a probabilistic sparseness constrained optimization by introducing suitable hierarchical priors as sparsity constraints. A fast relevance vector machine (RVM) is then employed to reconstruct the scatterers as well as to estimate the “confidence level” of the inversion. Representative numerical results are presented to illustrate the method as well as to assess its potentialities and limitations in terms of inversion accuracy, computational efficiency, and robustness. Comparisons with state-of-the-art deterministic and stochastic reconstruction methodologies still within the Born approximation (BA) are discussed, as well.
Experimental validation of an adaptive control for a Voltage Source Converter

In this work an adaptive controller is designed to provide reactive power compensation and dc voltage tracking of a three phase Voltage Source Converter (VSC). The method relies on a third order model of the VSC which accounts for uncertainty in three system parameters. The proposed method ensures asymptotic tracking of reactive power and dc voltage. Simulation and experimental results verify the performance of the controller.
Genome-wide Analyses of Carboxyl-terminal Sequences*

Sequence motifs at the protein carboxyl termini in linear polypeptides are uniquely positioned and functionally capable of serving as recognition signatures for a variety of cellular and biochemical processes. At the proteome level, it is unknown whether and what carboxyl-terminal sequences might be particularly conserved, which may be directly related to specific biological functions shared among certain groups of proteins. To investigate this question, we analyzed the terminal sequences of reported yeast open reading frames, which presumably constitute the predicted, entire proteome of Saccharomyces cerevisiae. The results show that there are both known and novel terminal sequences. They are conserved at a frequency similar to that of functionally important, experimentally confirmed signals such as the HDEL sequence that mediates the endoplasmic reticulum retention and/or retrieval. The findings support the notion that there may be additional carboxyl-terminal signals, and the conserved motifs could be experimentally tested for currently unknown biological functions. Similar analyses were also applied to the limited proteome databases of other organisms with overall consistent findings. Therefore, indexing a proteome according to its carboxyl-terminal sequences may provide a means for functional classification and determination of proteins.
Effects of oxymorphone and hydromorphone on the minimum alveolar concentration of isoflurane in dogs.

OBJECTIVES To quantify the change in the minimum alveolar concentration (MAC) of isoflurane (ISO) associated with oxymorphone (OXY) or hydromorphone (HYDRO) in dogs. DESIGN Randomized crossover study with at least 1 week between assessments. ANIMALS Six young, healthy, mixed-breed dogs (1-3 years old), weighing 24.7 +/- 4.70 kg. METHODS Following mask induction, anesthesia was maintained with ISO in 100% O(2) using mechanical ventilation. The dogs received 0.05 mg kg(-1) OXY, 0.1 mg kg(-1) HYDRO, or 1 mL saline (control) IV. Following equilibration (15 minutes) at each percentage ISO tested, a supramaximal electrical stimulus was applied to the toe web and the response was assessed. Two separate MAC determinations were carried out during 4.5 hours of anesthesia, with completion of the evaluations at 1.5-2 and 4-4.5 hours after drug administration. A two-factor anova was used to determine whether there was a time or treatment effect on MAC and a Tukey test compared the drug effects at each time. Significance is reported at p < 0.05. RESULTS The mean MAC values (+/-SD) were 1.2 +/- 0.18 and 1.2 +/- 0.16% for control, 0.7 +/-0.15 and 1.0 +/- 0.15% for OXY, and 0.6 +/- 0.14 and 0.8 +/- 0.17% for HYDRO. The initial MAC with OXY and the MAC determined at both times with HYDRO were significantly different from the control MAC values. CONCLUSIONS Both OXY and HYDRO significantly reduced the MAC of ISO in dogs at 2 hours. At approximately 4.5 hours, HYDRO had a significant MAC-sparing effect, whereas OXY did not. CLINICAL RELEVANCE Although both OXY and HYDRO resulted in a significant reduction in the MAC of ISO at approximately 2 hours, HYDRO may be preferred for procedures of long duration and rarely needs repeated dosing before 4.5 hours.
Comment on “ A reassessment of the groundwater inverse problem ”

Many methods are available for the solution of the following inverse problem: determine the conductivity or transmissivity of a porous medium from head or pressure observations and other information. McLaughlin and Townley [1996] (hereinafter referred to as MT) review a family of methods and present maximum a posteriori estimation and a functional formulation as common characteristics of prevailing methodologies. The authors deserve due credit for their efforts to unify seemingly disparate approaches. It is hard, however, to squeeze different methods into a narrow mold without knocking them out of shape. My objective is to clarify and supplement some important points made by MT in order to make this work more useful, particularly to readers who may be interested in using the “geostatistical approach. ” I will focus on estimation (also known as inference) issues using the first two statistical moments, leaving aside the other important questions of how to solve the forward problem, determine sensitivity matrices, or use other statistics. My key points are as follows: 1. The geostatistical approach does not fit within the narrow definition of maximum a posteriori estimation adopted by MT; an alternative study of the relation between Bayesian estimation and geostatistical analysis is that of Kitanidis [1986]. 2. The geostatistical approach is well suited to function estimation, a point that was missed by MT. 3. The structural analysis part of inverse modeling, which was neglected by MT is at least as important as the “least squares” or “conditioning” part that is the focus of MT.
Psychological Functioning in a Cohort of Gay Men at Risk for AIDS: A Three-Year Descriptive Study

This study describes the mental health of a large cohort of gay men participating in the Chicago Multicenter AIDS Cohort Study/Coping and Change Study. Six biannual questionnaires were self-administered between 1984 and 1988. General mental health was determined by the Hopkins Symptom Checklist (HSCL). An abbreviated version of the Center for Epidemiologic Study Depression Scale (CESD-5) and an adapted Diagnostic Interview Schedule (DIS) question also measured depression. Suicidal ideation was assessed by one question in the HSCL. AIDS-specific distress was determined by three subscales specifically developed for this study While mean HSCL and CESD-5 scores were stable during the observational period, AIDSspecific distress increased over time. The HSCL scores for the cohort were somewhat elevated above general population norms but considerably below psychiatric outpatient norms. Fewer than 12% of the men reported elevated HSCL or CESD-5 scores three or more times. A self-reported episode of depression of two weeks or more, measured by the DIS screening question, was experienced by 40.1% of the sample. Suicidal ideation was reported on three or more visits by 18.8% of the men The younger members of this cohort exhibit greater general and AIDS-specific distress. Income was inversely associated with general distress. HIV-seropositive participants had generally higher AIDS-specific distress scores than those who were seronegative, but their scores were equivalent on the HSCL and CESD-5
Suicide in Dublin: I. The Under-reporting of Suicide and the Consequences for National Statistics

Summary This study of suicide in Dublin during 1964–1968 from coroners' records was undertaken to estimate the discrepancy between coroners' verdicts, the national suicide statistics compiled from them and the clinical assessment of probability of suicide by psychiatrists examining the same records. The large difference in numbers of suicides deriving from the two approaches has considerable implications for national suicide statistics, and these have been briefly considered. From the findings presented we believe that we are justified in concluding that: (a) there are real differences in national suicide rates, at least between Ireland, England and Wales, and Scotland, and (b) the Irish suicide rate is low, though not as low as official statistics suggest, and (c) the discrepancy between official and ‘true’ suicide rates in Ireland is greater than in England and Wales and in Scotland.
Discontinuous hybrid modulation technique for three-phase three-level neutral point clamped inverters

Multilevel converters are widely used in high-power applications such as motor drives, utility applications, and, more recently, photovoltaic and wind generation systems. A number of modulation strategies have been proposed in literature in the particular case of three-phase three-level NPC topology, each one focusing on the optimization of specific aspects and performance of the converter, such as efficiency and neutral point (NP) balancing. In this paper a new discontinuous hybrid modulation technique is presented, obtained by combining discontinuous (DPWM) and hybrid (HPWM) pulse width modulations. By sharing the advantages of both techniques a reduction of switching and conduction losses is obtained, control of the low frequency component of NP ripple is maintained and an additional degree of freedom for its active control is theoretically available. Simulation and experimental results based on a TMS320F28035 DSP controller and a NPC three level inverter are presented to confirm the effectiveness of the proposal.
An Accessible Organotypic Microvessel Model Using iPSC‐Derived Endothelium

While organotypic approaches promise increased relevance through the inclusion of increased complexity (e.g., 3D extracellular microenvironment, structure/function relationships, presence of multiple cell types), cell source is often overlooked. Induced pluripotent stem cell (iPSC)‐derived cells are potentially more physiologically relevant than cell lines, while also being less variable than primary cells, and recent advances have made them commercially available at costs similar to cell lines. Here, the use of induced pluripotent stem cell‐derived endothelium for the generation of a functional microvessel model is demonstrated. High precision structural and microenvironmental control afforded by the design approach synergizes with the advantages of iPSC to produce microvessels for modeling endothelial biology in vitro. iPSC microvessels show endothelial characteristics, exhibit barrier function, secrete angiogenic and inflammatory mediators, and respond to changes in the extracellular microenvironment by altering vessel phenotype. Importantly, when deployed in the investigation of neutrophils during innate immune recruitment, the presence of the iPSC endothelial vessel facilitates neutrophil extravasation and migration toward a chemotactic source. Relevant cell sources, such as iPSC, combine with organotypic models to open the way for improved and increasingly accessible in vitro tissue, disease, and patient‐specific models.
On Direct and Semi-Direct Inverse of Stokes, Helmholtz and Laplacian Operators in View of Time-Stepper-Based Newton and Arnoldi Solvers in Incompressible CFD

Factorization of the incompressible Stokes operator linking pressure and velocity is revisited. The main purpose is to use the inverse of the Stokes operator with a large time step as a preconditioner for Newton and Arnoldi iterations applied to computation of steady three-dimensional flows and study of their stability. It is shown that the Stokes operator can be inversed within an acceptable computational effort. This inverse includes fast direct inverses of several Helmholtz operators and iterative inverse of the pressure matrix. It is shown, additionally, that fast direct solvers can be attractive for the inverse of the Helmholtz and Laplace operators on fine grids and at large Reynolds numbers, as well as for other problems where convergence of iterative methods slows down. Implementation of the Stokes operator inverse to time-stepping-based formulation of the Newton and Arnoldi iterations is discussed.
Asset allocation and regime switching on Croatian financial market

It has been known for quite some time now that financial markets exhibit changes in regimes over time. A majority of the literature tends to support that financial markets undergo regimes of bull and bear markets. This characteristic should be modeled in a proper way as investors are always interested in beating the market: either by achieving better returns than others, or by minimizing their portfolio risks. There exist many mathematical and statistical models that are used as tools to achieve the mentioned goals. Introducing the regime switching methodology in existing models has proven to be facilitate achieving such goals. Therefore, the objective of this study is to utilize the regime switching methodology on the Croatian financial market to ascertain its usefulness for Croatian investors. Multivariate regime switching and non-switching models were estimated using daily data from the period 2 January 2007 to 31 December 2015. The assumption is that the investor is interested in stock and bond markets. The results from the MGARCH and regime switching MGARCH models are then compared in order to give answers as to whether the respective methodology applied to the Croatian market is useful and how it may benefit investors. Most of the results support the presumption of incorporating this particular methodology in financial modeling for the Croatia markets. This is the first research that applies the regime switching MGARCH methodology in Croatia (including the Balkan region), hence we expect that this will be a significant contribution to existing methodologies in literature.

For a given combline resonator, perfect temperature compensations may be achieved at two different resonant frequencies by adjusting the tuning screws. A 4 GHz 8-pole filter is designed and tested. Satisfactory temperature compensation is obtained.
Delta-sigma subarray beamforming for ultrasound imaging

In this study, an ultrasonic digital beamformer based on subarray processing of 1-bit delta-sigma (D S ) oversampled echo signals is presented. The single-bit oversampling D S conversion simplifies the coherent processing in beamforming with improved timing accuracy. Subarray processing also aims to simplify the beamforming complexity, where the partial-beam sums (low-resolution beams) are acquired from small subarrays, and then these partial beams are coherently processed for producing high-resolution beams. In the D S subarray beamforming, the D S coded echo signals are summed over the subarray channels, and then these partial beam-sums are first D S demodulated, then processed for beam-interpolation, followed by coherent summation. This method requires decimation filtering of partial-beam sums from each subarray. The hardware complexity of the D S subarray beamformer is compared with other beamformers and significant front-end savings are explained. The system is tested experimentally and the results are compared with others using B-scan images reconstructed from archival experimental raw RF data. Both wire targets and cyst phantom are used to show the differences in Signal to Noise Ratio (SNR) and Contrast to Noise Ratio (CNR) measurements.
DENSITY DEPENDENCE, EVOLUTIONARY OPTIMIZATION, AND THE DIVERSIFICATION OF AVIAN LIFE HISTORIES

Abstract Although we have learned much about avian life histories during the 50 years since the seminal publications of David Lack, Alexander Skutch, and Reginald Moreau, we still do not have adequate explanations for some of the basic patterns of variation in life-history traits among birds. In part, this reflects two consequences of the predominance of evolutionary ecology thinking during the past three decades. First, by blurring the distinction between life-history traits and life-table variables, we have tended to divorce life histories from their environmental context, which forms the link between the life history and the life table. Second, by emphasizing constrained evolutionary responses to selective factors, we have set aside alternative explanations for observed correlations among life-history traits and life-table variables. Density-dependent feedback and independent evolutionary response to correlated aspects of the environment also may link traits through different mechanisms. Additionally, in some cases we have failed to evaluate quantitatively ideas that are compelling qualitatively, ignored or explained away relevant empirical data, and neglected logical implications of certain compelling ideas. Comparative analysis of avian life histories shows that species are distributed along a dominant slow-fast axis. Furthermore, among birds, annual reproductive rate and adult mortality are directly proportional to each other, requiring that pre-reproductive survival is approximately constant. This further implies that age at maturity increases dramatically with increasing adult survival rate. The significance of these correlations is obscure, particularly because survival and reproductive rates at each age include the effects of many life-history traits. For example, reproductive rate is determined by clutch size, nesting success, season length, and nest-cycle length, each of which represents the outcome of many different interactions of an individual's life-history traits with its environment. Resolution of the most basic issues raised by patterns of life histories clearly will require innovative empirical, modeling, and experimental approaches. However, the most fundamental change required at this time is a broadening of the evolutionary ecology paradigm to include a variety of alternative mechanisms for generating patterns of life-history variation.
Distributed Negative Sampling for Word Embeddings

Word2Vec recently popularized dense vector word representations as fixed-length features for machine learning algorithms and is in widespread use today. In this paper we investigate one of its core components, Negative Sampling, and propose efficient distributed algorithms that allow us to scale to vocabulary sizes of more than 1 billion unique words and corpus sizes of more than 1 trillion words.
A Survey of Raaga Recognition Techniques and Improvements to the State-of-the-Art

Raaga is the spine of Indian classical music. It is the single most crucial element of the melodic framework on which the music of the subcontinent thrives. Naturally, automatic raaga recognition is an important step in computational musicology as far as Indian music is considered. It has several applications like indexing Indian music, automatic note transcription, comparing, classifying and recommending tunes, and teaching to mention a few. Simply put, it is the first logical step in the process of creating computational methods for Indian classical music. In this work, we investigate the properties of a raaga and the natural process by which people identify the raaga. We survey the past raaga recognition techniques correlating them with human techniques, in both north Indian (Hindustani) and south Indian (Carnatic) music systems. We identify the main drawbacks and propose minor, but multiple improvements to the state-of-the-art raaga recognition technique.
Histone-Dependent Association of Tup1-Ssn6 with Repressed Genes In Vivo

ABSTRACT The Tup1-Ssn6 complex regulates diverse classes of genes in Saccharomyces cerevisiae and serves as a model for corepressor functions in many organisms. Tup1-Ssn6 does not directly bind DNA but is brought to target genes through interactions with sequence-specific DNA binding factors. Full repression by Tup1-Ssn6 appears to require interactions with both the histone tails and components of the general transcription machinery, although the relative contribution of these two pathways is not clear. Here, we map Tup1 locations on two classes of Tup1-Ssn6-regulated genes in vivo via chromatin immunoprecipitations. Distinct profiles of Tup1 are observed on a cell-specific genes and DNA damage-inducible genes, suggesting that alternate repressive architectures may be created on different classes of repressed genes. In both cases, decreases in acetylation of histone H3 colocalize with Tup1. Strikingly, although loss of the Srb10 mediator protein had no effect on Tup1 localization, both histone tail mutations and histone deacetylase mutations crippled the association of Tup1 with target loci. Together with previous findings that Tup1-Ssn6 physically associates with histone deacetylase activities, these results indicate that the repressor complex alters histone modification states to facilitate interactions with histones and that these interactions are required to maintain a stable repressive state.
