Matrix permanent and quantum entanglement of permutation invariant states

We point out that a geometric measure of quantum entanglement is related to the matrix permanent when restricted to permutation invariant states. This connection allows us to interpret the permanent as an angle between vectors. By employing a recently introduced permanent inequality by Carlen et al. [Methods Appl. Anal. 13, 1 (2006)], we can prove explicit formulas of the geometric measure for permutation invariant basis states in a simple way.
Cooling Practices Used in School Foodservice

a nationwide online survey of 411 school foodservice managers/directors was conducted to identify current practices used for cooling foods in school districts and to determine whether these practices have changed since the implementation of the required food safety program based on haCCP principles in 2006. a majority of respondents (78%) cool leftovers to reheat and serve at another meal in addition to cooling a variety of foods such as turkey, pork, or beef roasts, taco meat, spaghetti and marinara sauces, and soups. Only 8% have blast chillers available to support cooling. While most respondents reported using 2” pans for cooling, a number of schools reported using stockpots and 4” and 6” counter pans. Temperatures were monitored by most respondents; however, 18% did not monitor temperatures and 12% used an incorrect type of thermometer. Reported cooling practices indicate that many school foodservice workers are taking measures to speed cooling. The major challenges to proper cooling are the short work day of school employees and inadequate funds to purchase adequate equipment. Based on these results, strategies to improve cooling effectiveness can be developed. INTRODUCTION
Identifying the features of an exercise addiction: A Delphi study

Objectives There remains limited consensus regarding the definition and conceptual basis of exercise addiction. An understanding of the factors motivating maintenance of addictive exercise behavior is important for appropriately targeting intervention. The aims of this study were twofold: first, to establish consensus on features of an exercise addiction using Delphi methodology and second, to identify whether these features are congruous with a conceptual model of exercise addiction adapted from the Work Craving Model. Methods A three-round Delphi process explored the views of participants regarding the features of an exercise addiction. The participants were selected from sport and exercise relevant domains, including physicians, physiotherapists, coaches, trainers, and athletes. Suggestions meeting consensus were considered with regard to the proposed conceptual model. Results and discussion Sixty-three items reached consensus. There was concordance of opinion that exercising excessively is an addiction, and therefore it was appropriate to consider the suggestions in light of the addiction-based conceptual model. Statements reaching consensus were consistent with all three components of the model: learned (negative perfectionism), behavioral (obsessive–compulsive drive), and hedonic (self-worth compensation and reduction of negative affect and withdrawal). Conclusions Delphi methodology allowed consensus to be reached regarding the features of an exercise addiction, and these features were consistent with our hypothesized conceptual model of exercise addiction. This study is the first to have applied Delphi methodology to the exercise addiction field, and therefore introduces a novel approach to exercise addiction research that can be used as a template to stimulate future examination using this technique.
Behavioral Synthesis of Asynchronous Circuits Using Syntax Directed Translation as Backend

The current state-of-the art in high-level synthesis of asynchronous circuits is syntax directed translation, which performs a one-to-one mapping of an HDL-description into a corresponding circuit. This paper presents a method for behavioral synthesis of asynchronous circuits which builds on top of syntax directed translation, and which allows the designer to perform automatic design space exploration guided by area or speed constraints. This paper presents an asynchronous implementation template consisting of a data-path and a control unit and its implementation using the asynchronous hardware description language Balsa. This ldquoconventionalrdquo template architecture allows us to adapt traditional synchronous synthesis techniques for resource sharing, scheduling, binding, etc., to the domain of asynchronous circuits. A prototype tool has been implemented on top of the Balsa framework, and the method is illustrated through the implementation of a set of example circuits. The main contributions of this paper are the fundamental idea, the template architecture and its implementation using asynchronous handshake components, and the implementation of a prototype tool.
Climate-driven variation in food availability between the core and range edge of the endangered northern bettong (Bettongia tropica)

The endangered northern bettong (Bettongia tropica) occurs in four disjunct populations in far north Queensland, Australia, at a high density only in its range core (RC). A recent study suggested that B. tropica populations are sparse at the northern and southern range edges (SRE) due to more severe droughts and variable climatic conditions causing fluctuations in the availability of their principal food resource, truffle-like fungi. Truffle availability in the Australian tropics is affected by climate, specifically seasonality of precipitation. We aimed to determine whether the differences in weather patterns between the RC and SRE could be translated to actual differences in truffle availability. Truffle density was consistently lower on the SRE although biomass was slightly higher there due to dominance by drought-tolerant truffle taxa that produce few but large truffles. Lower densities of truffles on the SRE could explain why B. tropica is also less abundant there and why they may be less resilient to competition from the more generalist rufous bettong (Aepyprymnus rufescens). Increasing temperatures and, more importantly, harsher droughts predicted for this region as a result of climate change, may have further detrimental impacts on truffle availability and thus population densities of B. tropica and other mycophagous species.
Experimental investigation of correlation properties of MIMO radio channels for indoor picocell scenarios

The present paper describes the set-up for the measurement of MIMO (multi-input-multi-output) radio channels as part of the European project METRA (Multi Element Transmit and Receive Antenna). Inputs for the stochastic model described by Pedersen, Andersen, Kermoal and Mogensen (see IEEE Vehicular Technology Conference VTC 2000 Fall, Boston, USA, 2000) are extracted from the measurement results and fed into a COSSAP(R) block implementing this model. A good matching between the eigenanalysis performed on both measured and simulated signals is shown.
The CIDA-UCM-Yale Shallow Survey for Emission Line Galaxies

We present the CIDA-UCM-Yale (Centro de Investigaciones de Astronomia, Universidad Complutense de Madrid, and Yale University) Survey (CUYS) for Hα + [N II] 6549, 6584 A emission-line galaxies (ELGs) using objective-prism spectra. The most important properties of a catalogue with 427 entries and significant subsets are analysed. The complete sample contains 183 statistically confirmed ELGs in a sky area of 151 deg^2 and redshift up to 0.14. We determine the parameters of the Ha luminosity function using the Hα + [N II] flux directly measured on the ELG spectra in this sample, and the star formation rate density derived is in agreement with values reported in the literature. Finally, we study the clustering properties of local star-forming galaxies relative to quiescent ones from different perspectives. We find that ELGs avoid dense regions of quiescent galaxies and we propose a power-law expression to parametrize the relation between star formation rate density and environment volume density of ELGs.
C-Type Lectin-Like Receptors of the Dectin-1 Cluster: Ligands and Signaling Pathways

Innate immunity is constructed around genetically encoded receptors that survey the intracellular and extracellular environments for signs of invading microorganisms. These receptors recognise the invader and through complex intracellular networks of molecular signaling, they destroy the threat whilst instructing effective adaptive immune responses. Many of these receptors, like the Toll-like receptors in particular, are well-known for their ability to mediate downstream responses upon recognition of exogenous or endogenous ligands; however, the emerging family known as the C-type lectin-like receptors contains many members that have a huge impact on immune and homeostatic regulation. Of particular interest here are the C-type lectin-like receptors that make up the Dectin-1 cluster and their intracellular signaling motifs that mediate their functions. In this review, we aim to draw together current knowledge of ligands, motifs and signaling pathways, present downstream of Dectin-1 cluster receptors, and discuss how these dictate their role within biological systems.
Effect of LiDAR derived DEM resolution on terrain attributes, stream characterization and watershed delineation

A raster grid with 1m spacing was created using simple kriging from LiDAR point clouds. The 2, 3, 4, 5, 8, and 10 m resolution were created from the original 1 m DEM using nearest neighbor resampling method. The derived DEM were used to study the sensitivity of terrain attributes while changing DEM resolution and possibly introduce a minimum required resolution for the study area. A variety of terrain attributes were calculated to analyze their rate of changes in different resolutions. Using a coarser DEM resolution (8 and 10 m) instead of a finer one (1, 2 and 3 m), tends to ignore a variety of valuable features, and changes spatial distribution of terrain attributes. It also changes minimum, maximum and standard deviation of elevation within each unit leading to smoother output images. Large differences were observed between 1 and 10 m on all topographical and hydrological attributes, implying that the 10 m DEM is too coarse for this landscape to extract streamlines, and landform attributes. Landform elements were the most sensitive among other tested attributes. The plan curvature trends indicated that a 4 m DEM is capable to capture the grain and the longest significant relief wavelength across slopes, at least in this landscape; this implies that 4 m grid size can be the minimum DEM resolution to study the relief changes accurately, in this particular landscape.
Buying your way into heaven : education and corruption in international perspective

Education is commonly thought to be a haven for the young. No matter how unstable the polity, no matter how dismal the prospects for the economy, education investments are often treated as sacrosanct. This is one reason for the popularity of education as part of foreign aid. Who could object to providing more opportunity for young people to study? Recently however, it has been discovered that education systems can be as corrupt as other parts of government and the economy; and that values of fairness and impartiality, once thought to be universal characteristics of education systems, can be supplanted by the interests of specifi c individuals, families and ethnic groups. Education corruption has now been found in all regions of the world, but it manifests itself in different ways. How do these differ from one region to another? What should be done to minimize education corruption? And what should be done to protect universities and employers in areas situated where there is little corruption from the products of those parts of the world where education corruption is the norm. This book will explain the meaning of education corruption and how it works; it will provide illustrations from Asia, Africa, Southeastern Europe and the former Soviet Union, and it will propose actions and policies on the part of regional and international agencies to counter-act what is now likely to become a new and unexpected global crisis.
Numerics for liquid crystals with variable degree of orientation

We consider the simplest one-constant model, put forward by J. Eriksen, for nematic liquid crystals with variable degree of orientation. The equilibrium state is described by a director field n and its degree of orientation s , where the pair ( n , s ) minimizes a sum of Frank-like energies and a double well potential. In particular, the Euler-Lagrange equations for the minimizer contain a degenerate elliptic equation for n , which allows for line and plane defects to have finite energy. Using a special discretization of the liquid crystal energy, and a strictly monotone energy decreasing gradient flow scheme, we present a simulation of a plane-defect in three dimensions to illustrate our method.
Surface circulation and temperature distribution of Southern South China Sea from Global Ocean Model (OCCAM)

The South China Sea (SCS) circulation in its southern region in the area between Peninsular Malaysia and East Malaysia was studied from the OCCAM (Ocean Circulation and Climate Advanced Modelling). This research aimed to illustrate the general overview of the seasonal surface current circulation and the surface temperature profile which are lacking in the region. The current along the Malaysia coast flows northward in the southwest monsoon and move in opposite direction in northeast monsoon with the maximum speed of 0.4 m/s and 1 m/s, respectively. While the current flows southward, the cooler water is transported into the region which reduces the temperature at the central of the basins nearly 3 °C. The study manages to analyse the importance of the monsoonal system on the region circulation and temperature distribution.
Chronic cough in patients with sleep-disordered breathing

Chronic cough can be the sole presenting symptom for patients with obstructive sleep apnoea. We investigated the prevalence, severity and factors associated with chronic cough in patients with sleep-disordered breathing (SDB). We invited 108 consecutive patients who had been referred for evaluation of SDB to complete a comprehensive questionnaire on respiratory and sleep health, which included the Leicester Cough Questionnaire (cough specific quality of life; LCQ), Epworth Sleepiness Scale (ESS) and the Mayo Clinic gastro-oesophageal questionnaire. Chronic cough was defined as cough for a duration of >2 months. 33% of patients with SDB reported a chronic cough. Patients with a chronic cough had impaired cough related-quality of life affecting all health domains (mean±sem LCQ score 17.7±0.7; normal = 21). Patients with SDB and chronic cough were predominantly females (61% versus 17%; p<0.001) and reported more nocturnal heartburn (28% versus 5%; p = 0.03) and rhinitis (44% versus 14%; p = 0.02) compared to those without SDB. There were no significant differences in ESS, respiratory disturbance index, body mass index, or symptoms of breathlessness, wheeze, snoring, dry mouth and choking between those with cough and those without. Chronic cough is prevalent in patients with SDB and is associated with female sex, symptoms of nocturnal heartburn and rhinitis. Further studies are required to investigate the impact of continuous positive airway pressure therapy on cough associated with SDB to explore the mechanism of this association.
microRNA-222 Controls Neovascularization by Regulating Signal Transducer and Activator of Transcription 5A Expression

Objective—Inflammatory stimuli released into atherosclerotic plaque microenvironment regulate vessel formation by modulating gene expression and translation. microRNAs are a class of short noncoding RNAs, acting as posttranscriptional regulators of protein-coding genes involved in various biological processes, including vascular cell biology. Among them, microRNA-221/222 (miR-221/222) seem to negatively modulate vascular remodeling by targeting different target genes. Here, we investigated their potential contribution to inflammation-mediated neovessel formation. Methods and Results—We used quantitative real-time RT-PCR amplification to analyze expression of 7 microRNAs previously linked to vascular biology, such as miR-17-5p, miR-21, miR-126, miR-210, miR-221, miR-222, and miR-296 and found high levels of expression for all of them in quiescent endothelial cells. However, miR-126, miR-221, miR-222, and miR-296 turned out to be down-modulated in endothelial cells exposed to inflammatory stimuli. Applying a gain-of-function approach, we demonstrated that, among them, only miR-222 was involved in inflammation-mediated vascular remodeling. In addition, we identified signal transducer and activator of transcription 5A (STAT5A) as a bona fide target of miR-222 and observed that miR-222 negatively correlated with STAT5A expression in human endothelial cells from advanced neovascularized atherosclerotic lesions. Conclusion—We identified STAT5A as a novel miR-222 target, and this finding opens up new perspectives for treatment of vascular diseases.
Effect of Repeated Electroacupuncture Intervention on Hippocampal ERK and p38MAPK Signaling in Neuropathic Pain Rats

Results of our past studies showed that hippocampal muscarinic acetylcholine receptor (mAChR)-1 mRNA and differentially expressed proteins participating in MAPK signaling were involved in electroacupuncture (EA) induced cumulative analgesia in neuropathic pain rats, but the underlying intracellular mechanism remains unknown. The present study was designed to observe the effect of EA stimulation (EAS) on hippocampal extracellular signal-regulated kinases (ERK) and p38 MAPK signaling in rats with chronic constrictive injury (CCI) of the sciatic nerve, so as to reveal its related intracellular targets in pain relief. After CCI, the thermal pain thresholds of the affected hind were significantly decreased compared with the control group (P < 0.05). Following one and two weeks' EAS of ST 36-GB34, the pain thresholds were significantly upregulated (P < 0.05), and the effect of EA2W was remarkably superior to that of EA2D and EA1W (P < 0.05). Correspondingly, CCI-induced decreased expression levels of Ras, c-Raf, ERK1 and p-ERK1/2 proteins, and p38 MAPK mRNA and p-p38MAPK protein in the hippocampus tissues were reversed by EA2W (P < 0.05). The above mentioned results indicated that EA2W induced cumulative analgesic effect may be closely associated with its function in removing neuropathic pain induced suppression of intracellular ERK and p38MAPK signaling in the hippocampus.
From business process outsourcing (BPO) to knowledge process outsourcing (KPO): Some issues

There has been a growth in the amount of outsourcing in general and business process outsourcing in particular. Now a number of firms are beginning to outsource knowledge processes as well. This is being partly fuelled by an increasing shortage of skilled labor in industrialized countries while some emerging nations have a large pool of highly skilled workers at lower wages. Technological, political, and strategic changes and an improved ability to manage the inherent risks are some of the other reasons explaining its potential growth. Providers of these services are either moving up the knowledge intensity value chain with existing clients or are entering new opportunities in specific industries such as healthcare/pharmaceutical, legal and financial services. These services are more profitable to the providers than the standard business process outsourcing but require more expensive investments in infrastructure as well as specialized skill sets with more depth and domain knowledge. The structuring and management of this type of outsourcing is also very complex and fraught with new risks. This paper presents a number of issues related to knowledge process outsourcing from the client firm and the provider's perspectives. The issues are derived from five cases studied by the authors in India and Ireland.
ScienceTreks: an autonomous digital library system

PurposeThe purpose of this paper is to provide support for automation of the annotation process of large corpora of digital content.Design/methodology/approachThe paper presents and discusses an information extraction pipeline from digital document acquisition to information extraction, processing and management. An overall architecture that supports such an extraction pipeline is detailed and discussed.FindingsThe proposed pipeline is implemented in a working prototype of an autonomous digital library (A‐DL) system called ScienceTreks that: supports a broad range of methods for document acquisition; does not rely on any external information sources and is solely based on the existing information in the document itself and in the overall set in a given digital archive; and provides application programming interfaces (API) to support easy integration of external systems and tools in the existing pipeline.Practical implicationsThe proposed A‐DL system can be used in automating end‐to‐end information retrieval and processing, supporting the control and elimination of error‐prone human intervention in the process.Originality/valueHigh quality automatic metadata extraction is a crucial step in the move from linguistic entities to logical entities, relation information and logical relations, and therefore to the semantic level of digital library usability. This in turn creates the opportunity for value‐added services within existing and future semantic‐enabled digital library systems.
Variants of intrinsic disorder in the human proteome

In this paper we propose a straightforward operational definition of variants of disordered proteins, taking the human proteome as a case study. The focus is on a distinction between mostly unstructured proteins and proteins which contain long unstructured regions accommodated in an overall folded structure. In particular we distinguish: i) Not disordered proteins (NDPs), that either have all their residues ordered or do not have disordered segments longer than 30 residues nor more than 30% of disordered residues; ii) Proteins with intrinsically disordered regions (IDRPs), that have at least one disordered domain longer than 30 residues, but disordered in less than 30% of their residues; iii) Proteins that are intrinsically disordered (IDPs), that have both at least one disordered segment longer than 30 residues and that are disordered on more than 30% of their residues; iv) Proteins with fragmented disorder (FRAG_IDPs), that do not have a disordered fragment longer than 30 residues but that, nevertheless, have at least 30% or more of their residues predicted as disordered. The potential use of these variants is checked over several groups of disease-related proteins. Our main conclusions point out that IDRPs are more similar to NDPs than to IDPs. IDRPs and NDPs have a similar functional repertoire and probably share a lock-and-key mechanism of interaction with substrates. IDRPs and IDPs are differently present among human disease-related proteins. IDRPs probably do not play a specific role in the development of complex diseases, since their frequency is similar in disease-related proteins and in the entire human proteome. IDPs can play a role in the emergence of cancer, neurodegenerative, thyroid and liver disease.
