Modeling for the design of fractional slot PM machines with concentrated windings protected from demagnetization during three-phase short circuit

This paper presents a guideline for determining the thickness of permanent magnets in fractional slot permanent magnet machines with concentrated windings so that demagnetization can be alleviated or avoided even during three-phase short circuit fault. An analytical model for calculating the magnetic field, inductance, and three-phase short circuit current is investigated. A transient two-dimension FEM model including rotor motion and coupling with a circuit model is developed for checking the partial demagnetization of magnets. Analytical calculation, FEM simulation, and experimental results of synchronous inductance and three-phase short circuit show good agreement.
Isolation and Characterization of Aquatic-Borne Klebsiella pneumoniae from Tropical Estuaries in Malaysia

Klebsiella pneumoniae is an opportunistic pathogen that is responsible for causing nosocomial and community-acquired infections. Despite its common presence in soil and aquatic environments, the virulence potential of K. pneumoniae isolates of environmental origin is largely unknown. Hence, in this study, K. pneumoniae isolated from the estuarine waters and sediments of the Matang mangrove estuary were screened for potential virulence characteristics: antibiotic susceptibility, morphotype on Congo red agar, biofilm formation, presence of exopolysaccharide and capsule, possession of virulence genes (fimH, magA, ugE, wabG and rmpA) and their genomic fingerprints. A total of 55 strains of K. pneumoniae were isolated from both human-distributed sites (located along Sangga Besar River) and control sites (located along Selinsing River) where less human activity was observed, indicated that K. pneumoniae is ubiquitous in the environment. However, the detection of potentially virulent strains at the downstream of Kuala Sepetang village has suggested an anthropogenic contamination source. In conclusion, the findings from this study indicate that the Matang mangrove estuary could harbor potentially pathogenic K. pneumoniae with risk to public health. More studies are required to compare the environmental K. pneumoniae strains with the community-acquired K. pneumoniae strains.
Sparse reconstruction for compressed sensing using Stagewise Polytope Faces Pursuit

Compressed sensing, also known as compressive sampling, is an approach to the measurement of signals which have a sparse representation, that can reduce the number of measurements that are needed to reconstruct the signal. The signal reconstruction part requires efficient methods to perform sparse reconstruction, such as those based on linear programming. In this paper we present a method for sparse reconstruction which is an extension of our earlier Polytope Faces Pursuit algorithm, based on the polytope geometry of the dual linear program. The new algorithm adds several basis vectors at each stage, in a similar way to the recent Stagewise Orthogonal Matching Pursuit (StOMP) algorithm. We demonstrate the application of the algorithm to some standard compressed sensing problems.
"STRETCH": a system for document storage and retrieval by content

A system for storing and retrieving imaged multimedia documents by content is described. This system is being developed within the Esprit project STRETCH (STorage and RETrieval by Content of imaged documents). The core of STRETCH system is a powerful archiving and retrieval engine, based on a structured document representation and capable of activating appropriate methods to characterise and automatically index heterogeneous documents with variable layout and subsequently retrieve them by answering to complex queries. The produced document base, or "Docu-base", relies on an object oriented internal representation and related characterisation and search methods. A prototype was implemented and successfully tested, in particular, in the creation of an invoice archive.
146 Treatment of Headache

In an epidemiological study of migraine [2] using a self-administered questionnaire filled out by 23,611 individuals from 9,507 American households, 17.6% of women and 5.7% of men between ages 12 and 80 years had headaches that met a definition of migraine that was based on a modification of the International Headache Society’s criteria [1]. Projections from this study to the country as a whole indicate that 18 million women and 5.6 million men over age 12 suffer from severe migraine headaches. Diagnostic criteria for migraine with and without an aura are given in >Table 146‐2. Among these individuals, a projected 8.7 million women and 2.6 million men have moderate to severe disability from headache [2]. Fifty-five percent of men and seventy-two percent of women never consult a doctor for a headache problem [3]. Among those who seek medical attention, 44.5% of men and 46.3% of women consult family practitioners. With increasing awareness of headache as a biological problem, it is expected that a larger number of migraine patients will seek help for this condition. Migraine can occur with or without an aura (warning symptoms). The most common aura is visual in nature, although neurological auras such as hemisensory disturbances, hemiparesis, dysphasia, and changes in memory and state of consciousness occur occasionally.

Velocity dispersion in GaN-based surface acoustic wave filters on (0001) sapphire substrates

We fabricated surface acoustic wave (SAW) filters on three nominally 2-µm-thick undoped GaN layers grown on (0001) sapphire substrates. We extracted SAW velocities for frequencies of the central and subsidiary peaks in the |S21| spectra by applying the δ-function model. We further obtained thicknesses of respective GaN layers by analysing their reflectivity spectra, and established the SAW velocity dispersion. The respective dispersion data were found to lie close to each other, which suggests that characteristics of GaN-based SAW devices can be designed with improved accuracy.
Comparative Visualization of Molecular Surfaces Using Deformable Models

The comparison of molecular surface attributes is of interest for computer aided drug design and the analysis of biochemical simulations. Due to the non‐rigid nature of molecular surfaces, partial shape matching is feasible for mapping two surfaces onto each other. We present a novel technique to obtain a mapping relation between two surfaces using a deformable model approach. This relation is used for pair‐wise comparison of local surface attributes (e.g. electrostatic potential). We combine the difference value as well as the comparability as derived from the local matching quality in a 3D molecular visualization by mapping them to color. A 2D matrix shows the global dissimilarity in an overview of different data sets in an ensemble. We apply our visualizations to simulation results provided by collaborators from the field of biochemistry to evaluate the effectiveness of our results.
Human Multipotent Adult Progenitor Cells Are Nonimmunogenic and Exert Potent Immunomodulatory Effects on Alloreactive T-Cell Responses

Multipotent adult progenitor cells (MAPCs) are bone marrow-derived nonhematopoietic stem cells with a broad differentiation potential and extensive expansion capacity. A comparative study between human mesenchymal stem cells (hMSCs) and human MAPCs (hMAPCs) has shown that hMAPCs have clearly distinct phenotypical and functional characteristics from hMSCs. In particular, hMAPCs express lower levels of MHC class I than hMSCs and cannot only differentiate into typical mesenchymal cell types but can also differentiate in vitro and in vivo into functional endothelial cells. The use of hMSCs as cellular immunomodulatory stem cell products gained much interest since their immunomodulatory capacities in vitro became evident over the last decade. Currently, the clinical grade stem cell product of hMAPCs is already used in clinical trials to prevent graft-versus-host disease (GVHD), as well as for the treatment of acute myocardial infarct, ischemic stroke, and Crohn's disease. Therefore, we studied the immune phenotype, immunogenicity, and immunosuppressive effect of hMAPCs in vitro. We demonstrated that hMAPCs are nonimmunogenic for T-cell proliferation and cytokine production. In addition, hMAPCs exert strong immunosuppressive effects on T-cell alloreactivity and on T-cell proliferation induced by mitogens and recall antigens. This immunomodulatory effect was not MHC restricted, which makes off-the-shelf use promising. The immunosuppressive effect of hMAPCs is partially mediated via soluble factors and dependent on indoleamine 2,3-dioxygenase (IDO) activity. At last, we isolated hMAPCs, the clinical grade stem cell product of hMAPCs, named MultiStem, and hMSCs from one single donor and observed that both the immunogenicity and the immunosuppressive capacities of all three stem cell products are comparable in vitro. In conclusion, hMAPCs have potent immunomodulatory properties in vitro and can serve as a valuable cell source for the clinical use of immunomodulatory cellular stem cell product.
The Sunyaev-Zel'dovich effect as a cosmological discriminator

We show how future measurements of the SZ effect (SZE) can be used to constrain the cosmological parameters. We combine the SZ information expected from the Planck full-sky survey, N(S), where no redshift information is included, with the N(z) obtained from an optically-identified SZ-selected survey covering less than 1 % of the sky. We demonstrate how with a small subsample (� 300 clusters) of the whole SZ catalogue observed optically it is possible to drastically reduce the degeneracy among the cosmological parameters. We have studied the requirements for performing the optical follow-up and we show the feasibility of such a project. Finally we have compared the cluster expectations for Planck with those expected for Newton-XMM during their lifetimes. It is shown that, due to its larger sky coverage, Planck will detect a factor � 5 times more clusters than Newton-XMM and also with a larger redshift coverage.
Predicting Falls In Individuals with Parkinson Disease: A Reconsideration of Clinical Balance Measures

Background and Purpose Postural control problems, falls, and fall-related injuries are a common source of morbidity in elderly individuals, especially those with Parkinson disease (PD). Clinical balance tests such as the Berg balance scale and the functional reach have been reported to be useful in assessing fall risk in elderly individuals. However, the utility of commonly used clinical balance tests as accurate screens for fall risk has not been sufficiently examined in persons with PD. The purposes of this study were to identify which commonly used clinical balance tests of persons with PD were predictive of falls, to re-examine the cut-of scores for these tests with the goal of maximizing sensitivity as well as minimizing the negative likelihood ratio, and to determine which of the clinical balance tests had the most value in predicting falls. Participants Forty-five persons with a diagnosis of idiopathic PD, aged 39–90 years (mean [sd] =69.94 [11.28]; mean [sd] Hoehn and Yahr level = 2.60 [.66]) participated. Methods Upon initial contact with participants, demographics and fall history were gathered and baseline physical examinations were performed. Each individual underwent balance testing with the functional reach test, the Berg balance scale, the dynamic gait index, timed up and go, and the cognitive timed up and go. Fallers and nonfallers were divided based on fall history and groups were compared on balance test performance. Sensitivity, specificity, likelihood ratios, and receiver operator characteristic curves were calculated for all balance tests. Results Twenty-five (55%) participants had a history of falls. Using cut-of scores reported in previous studies, the sensitivity of all tests was low (less than 0.60) and the specificity was high (greater than 0.85). Reconsideration of the cut-of scores resulted in increased sensitivity for all tests (greater than 0.75) and low negative likelihood ratios (less then .30). Discussion and Conclusion Given the large financial, psychological, and physical complications that are associated with a fall and relatively little harmful effects of fall prevention interventions, we propose consideration of cut-of scores that maximize sensitivity for individuals with PD. Regardless of the performance on any individual clinical balance test, the multifactorial nature of postural instability in PD may necessitate a battery of tests to provide the most accurate identification of fall risk.
Nonlinear operators for improving texture segmentation based on features extracted by spatial filtering

An unsupervised texture segmentation system using texture features obtained from a combination of spatial filters and nonlinear operators is described. Local texture features are evaluated in parallel by a succession of four basic operations: (1) a convolution for local structure detection (local linear transform); (2) a first nonlinearity of the form f(x)= mod x mod /sup alpha /; (3) an iterative smoothing operator; and (4) a second nonlinearity g(x). The Karhunen-Loeve transform is used to reduce the dimensionality of the resulting feature vector, and segmentation is achieved by thresholding or clustering in feature space. The combination of nonlinearities f(x)= mod x mod /sup alpha / (in particular, alpha =2) and g(x)=log x maximizes texture discrimination, and results in a description with variances approximately constant for all feature components and texture regions. This latter property improves the performance of both feature reduction and clustering algorithms significantly. >
Transient Receptor Potential Canonical Type 3 Channels Control the Vascular Contractility of Mouse Mesenteric Arteries

Transient receptor potential canonical type 3 (TRPC3) channels are non-selective cation channels and regulate intracellular Ca2+ concentration. We examined the role of TRPC3 channels in agonist-, membrane depolarization (high K+)-, and mechanical (pressure)-induced vasoconstriction and vasorelaxation in mouse mesenteric arteries. Vasoconstriction and vasorelaxation of endothelial cells intact mesenteric arteries were measured in TRPC3 wild-type (WT) and knockout (KO) mice. Calcium concentration ([Ca2+]) was measured in isolated arteries from TRPC3 WT and KO mice as well as in the mouse endothelial cell line bEnd.3. Nitric oxide (NO) production and nitrate/nitrite concentrations were also measured in TRPC3 WT and KO mice. Phenylephrine-induced vasoconstriction was reduced in TRPC3 KO mice when compared to that of WT mice, but neither high K+- nor pressure-induced vasoconstriction was altered in TRPC3 KO mice. Acetylcholine-induced vasorelaxation was inhibited in TRPC3 KO mice and by the selective TRPC3 blocker pyrazole-3. Acetylcholine blocked the phenylephrine-induced increase in Ca2+ ratio and then relaxation in TRPC3 WT mice but had little effect on those outcomes in KO mice. Acetylcholine evoked a Ca2+ increase in endothelial cells, which was inhibited by pyrazole-3. Acetylcholine induced increased NO release in TRPC3 WT mice, but not in KO mice. Acetylcholine also increased the nitrate/nitrite concentration in TRPC3 WT mice, but not in KO mice. The present study directly demonstrated that the TRPC3 channel is involved in agonist-induced vasoconstriction and plays important role in NO-mediated vasorelaxation of intact mesenteric arteries.
Dialectical behaviour therapy: An increasing evidence base

Background: Dialectical behaviour therapy (DBT) was originally developed and evaluated for the treatment of women diagnosed with borderline personality disorder (BPD) in the community. Since then the evidence base for its effectiveness has expanded considerably. Aims: To review the evidence base for the DBT model for BPD and the effectiveness of modified DBT for use with clients with co-morbid disorders, across the lifespan and across a range of clinical settings. Method: A review of the literature and clinical data from current services. Results: The efficacy of DBT for BPD has been shown in four RCTs. Across settings, modifications of DBT have been shown to be effective for individuals with co-morbid disorders and across the lifespan. Conclusions: DBT has an emerging evidence base for its effectiveness, primarily with individuals with BPD. Newer studies have begun to deconstruct the treatment model to identify the effective components. Declaration of interest: The author is a member of the UK DBT training team and receives funding from the Department of Health (UK) and the Department for Education and Skills.

Intelligent and fast two-dimensional CFAR procedure

In this paper, a intelligent and fast two-dimensional constant false alarm rate (CFAR) processor to perform adaptive threshold target detection is presented. It employs a composite approach based on the well-known cell averaging CFAR (CA-CFAR) and ordered statistic CFAR (OS-CFAR) processors. In this case, any masking effects in multi-target situations can be avoided without increasing the computation complexity. Besides, utilization of binary integration results in a higher detection performance. The simulation results verify the validity of the algorithm.
Dermagraft®, a bioengineered human dermal equivalent for the treatment of chronic nonhealing diabetic foot ulcer

Chronic nonhealing diabetic foot ulcers are a common medical problem that may precede severe complications such as infection, sepsis and limb loss. Current standard methods of treatment are aimed at removing necrotic debris, controlling infection, and relieving chronic pressure on the wound. Unfortunately, healing rates are poor with standard treatment, averaging 12–20 weeks in clinical trials. A new strategy for the treatment of diabetic foot ulcers has been developed through tissue engineering, allowing the application of healthy living skin cells to assist in the healing process. It is hoped that the living tissue will release appropriate quantities of growth factors, cytokines and other proteins to stimulate the chronic wound bed and accelerate healing. Dermagraft® (Smith & Nephew) is a neonatal-derived bioengineered tissue comprised of dermal fibroblasts. In this article, the structure and behavior of this tissue will be examined, focusing particularly on the randomized clinical trials performed to justify its use in diabetic foot ulcers.

Buzz: face-to-face contact and the urban economy

This paper argues that existing models of urban concentrations are incomplete unless grounded in the most fundamental aspect of proximity; face-to-face contact. Face-to-face contact has four main features; it is an efficient communication technology; it can help solve incentive problems; it can facilitate socialization and learning; and it provides psychological motivation. We discuss each of these features in turn, and develop formal economic models of two of them. Face-to-face is particularly important in environments where information is imperfect, rapidly changing, and not easily codified, key features of many creative activities.
Effects of Irradiance on the in Vivo CO(2):O(2) Specificity Factor in Tobacco Using Simultaneous Gas Exchange and Fluorescence Techniques.

The effects of gas phase O(2) concentration (1%, 20.5%, and 42.0%, v/v) on the quantum yield of net CO(2) fixation and fluorescence yield of chlorophyll a are examined in leaf tissue from Nicotiana tabacum at normal levels of CO(2) and 25 to 30 degrees C. Detectable decreases in nonphotochemical quenching of absorbed excitation occurred at the higher O(2) levels relative to 1% O(2) when irradiance was nearly or fully saturating for photosynthesis. Photochemical quenching was increased by high O(2) levels only at saturating irradiance. Simultaneous measurements of CO(2) and H(2)O exchange and fluorescence yield permit estimation of partitioning of linear photosynthetic electron transport between net CO(2) fixation and O(2)-dependent, dissipative processes such as photorespiration as a function of leaf internal CO(2) concentration. Changes in the in vivo CO(2):O(2) ;specificity factor' (K(sp)) with increasing irradiance are examined. The magnitude K(sp) was found to decline from a value of 85 at moderate irradiance to 68 at very low light, and to 72 at saturating photon flux rates. The results are discussed in terms of the applicability of the ribulose bisphosphate carboxylase/oxygenase enzyme model to photosynthesis in vivo.
Coupling analysis of transcutaneous energy transfer coils with planar sandwich structure for a novel artificial anal sphincter

This paper presents a set of analytical expressions used to determine the coupling coefficient between primary and secondary Litz-wire planar coils used in a transcutaneous energy transfer (TET) system. A TET system has been designed to power a novel elastic scaling artificial anal sphincter system (ES-AASS) for treating severe fecal incontinence (FI), a condition that would benefit from an optimized TET. Expressions that describe the geometrical dimension dependence of self- and mutual inductances of planar coils on a ferrite substrate are provided. The effects of ferrite substrate conductivity, relative permeability, and geometrical dimensions are also considered. To verify these expressions, mutual coupling between planar coils is computed by 3D finite element analysis (FEA), and the proposed expressions show good agreement with numerical results. Different types of planar coils are fabricated with or without ferrite substrate. Measured results for each of the cases are compared with theoretical predictions and FEA solutions. The theoretical results and FEA results are in good agreement with the experimental data.
