Influence of the Amount of Permanent-Magnet Material in Fractional-Slot Permanent-Magnet Synchronous Machines

The efficiency of permanent-magnet (PM) synchronous machines with outer rotor and concentrated windings is investigated as a function of the mass of magnets used, keeping the power, volume, and mechanical air-gap thickness constant. In order to be useful for electric vehicle motors and wind turbine generators, the efficiency is computed in wide speed and torque ranges, including overload. For a given type and amount of magnets, the geometry of the machine and the efficiency map are computed by analytical models and finite-element models, taken into account the iron loss, copper loss, magnet loss, and pulsewidth-modulation loss. The models are validated by experiments. Furthermore, the demagnetization risk and torque ripple are studied as functions of the mass of magnets in the machine. The effect of the mass of magnets is investigated for several soft magnetic materials, for several combinations of number of poles and number of stator slots, and for both rare earth (NdFeB) magnets and ferrite magnets. It is observed that the amount of PM material can vary in a wide range with a minor influence on the efficiency, torque density, and torque ripple and with a limited demagnetization risk.
Vasculitis in Systemic Lupus Erythematosus: Prevalence and Clinical Characteristics in 670 Patients

Abstract: We conducted the current study to determine the prevalence and clinical characteristics of vasculitis in a large series of patients with systemic lupus erythematosus (SLE), focusing on the classification and clinical significance of the different types of vasculitis. We studied 670 consecutive patients who fulfilled 4 or more of the 1997 revised criteria for SLE. Definite vasculitis was diagnosed histologically and/or by arteriography, and probable vasculitis was diagnosed clinically when there were characteristic cutaneous lesions. Vasculitides were categorized according to the definitions adopted by the Chapel Hill Consensus Conference. Seventy-six (11%) patients with SLE had vasculitis (68 female patients and 8 male; mean age, 37.8 yr); only 32 (42%) fulfilled the Chapel Hill definitions. Cutaneous lesions were the main clinical presentation of vasculitis, present in 68 (89%) patients, while the remaining 8 (11%) had isolated visceral vasculitis. Compared with SLE patients without vasculitis, patients with vasculitis had a higher prevalence of livedo reticularis (22% vs. 3%; p = 0.028); a higher mean European Consensus Lupus Activity Measurement (ECLAM) score (5.86 vs. 3.87; p < 0.001); and a higher frequency of anemia (62% vs. 17%; p < 0.001), erythrocyte sedimentation rate (ESR) >50 mm/h (60% vs. 15%; p < 0.001), and anti-La/SS-B antibodies (19% vs. 5%; p = 0.014) in the multivariate analysis. With respect to the size of the vessels involved, 65 (86%) patients had small vessel vasculitis (SVV) and 11 (14%) had medium-sized vessel vasculitis (MVV). SLE patients with MVV had a higher prevalence of mononeuritis multiplex (54% vs. 2%; p < 0.001), visceral vasculitis (100% vs. 5%; p < 0.001), and ulcerated/ischemic cutaneous lesions (36% vs. 11%; p = 0.047) and a higher percentage of surgical interventions (45% vs. 0%; p < 0.001) compared with patients with SVV. In conclusion, we observed a heterogeneous presentation of vasculitides arising in the setting of SLE, with nearly 60% of cases not fulfilling the names and definitions adopted by the Chapel Hill Consensus Conference. SVV was the most frequent vasculitis, overwhelmingly cutaneous and clearly differentiated from MVV, which was less frequent but had predominantly visceral involvement (especially of the peripheral nerves). The presence of vasculitis in our patients with SLE was associated with a higher ECLAM score, livedo reticularis, hematologic parameters (anemia, high ESR), and anti-La/SS-B antibodies.
Exploring the use of computational linguistics for automated formative feedback in the humanities

This paper presents the results an investigation into the possible role of computational linguistic techniques in providing automated formative feedback on student's written work including both traditional essays, and collaborative wikis. We first attempt to identify some of the criteria used by academic staff when marking student work. Using real examples from the School of Divinity at Edinburgh University, we analyse written feedback from the markers to produce an explicit list of criteria. We also use a number of automated tools to analyse certain features of the work and identify those which correlate with the perceived “quality”. We then survey various techniques from computational linguistics to determine how they might potentially be used to identify some of these criteria automatically. We conclude that there is a real potential to produce an automated tool which would provide practically useful formative feedback. We also note that the process of rigorously defining the criteria was helpful to the academic staff in clarifying their manual marking process.
Antioxidants: Balancing the Good, the Bad and the Ugly

Antioxidants refer to the molecules that react with oxy radicals not only to delay their function, but also to neutralize them and subsequently reduce oxidative stress and protect us from diseases state. Despite our own endogenous response, several factors contribute to diminish our self-defense mechanism resulting in loss of control in preventing ourselves from free radical damage. Antioxidant supplementation is becoming a high-priority to protect our health and from progression of several life-threatening diseases.
Sensor fault tolerant control of microgrid

This paper presents a sensor fault tolerant control approach for grid connected microgrids. The proposed approach diagnoses (detects and estimates) faults in the sensed microgrid output currents using sliding mode observer theory. Once a sensor fault is diagnosed, a mitigation action follows, which controls the output currents, using the estimated fault signals. The mitigation action ensures that the microgrid controller accurately generates pulse width modulation (PWM) signals so that the real and reactive powers output of the microgrid track their corresponding references. The accuracy and effectiveness of the proposed approach are verified through a case study, carried out on a grid connected microgrid.
Unified Optimization of Traffic Flows Through Airports

We present a novel integer optimization approach to optimize, in a tractable and unified manner, the airport operations optimization problem. This includes solving the entirety of key air traffic flow management problems faced at an airport: a selecting a runway configuration sequence, i.e., determining which runways are open at which times and in which mode they operate; b assigning flights to runways and determining the sequence in which flights are processed i.e., when they take off or land; c determining the gate-holding duration of departures; and d routing flights to their assigned runway and onward within the terminal area and the near-terminal airspace. The key contribution of this paper is the modeling of these problems, which until present have been studied in isolation, under a framework that is both unified and tractable. This allows the possibility of obtaining system-optimal solutions in a practical amount of time. Furthermore, the approach is implemented on historic data sets from both Boston Logan International and Dallas/Fort Worth International airports. Computational experience indicates that significant reductions in delays, fuel use, and emissions can be achieved from this optimization and that computational tractability is such that real-world instances can be solved within five to 10 minutes.
Suicide Inside: A Systematic Review of Inpatient Suicides

The literature on inpatient suicides was systematically reviewed. English, German, and Dutch articles were identified by means of the electronic databases PsycInfo, Cochrane, Medline, EMBASE psychiatry, CINAHL, and British Nursing Index. In total, 98 articles covering almost 15,000 suicides were reviewed and analyzed. Rates and demographic features connected to suicides varied substantially between articles, suggesting distinct subgroups of patients committing suicide (e.g., depressed vs. schizophrenic patients) with their own suicide determinants and patterns. Early in the admission is clearly a high-risk period for suicide, but risk declines more slowly for patients with schizophrenia. Suicide rates were found to be associated with admission numbers, and as expected, previous suicidal behavior was found to be a robust predictor of future suicide. The methods used for suicide are linked to availability of means. Timing and location of suicides seem to be associated with absence of support, supervision, and the presence of family conflict. Although there is a strong notion that suicides cluster in time, clear statistical evidence for this is lacking. For prevention of suicides, staff need to engage with patients' family problems, and reduce absconding without locking the door. Future research should take into account the heterogeneous subgroups of patients who commit suicide, with case-control studies addressing these separately.
Development of Theory-based, Online Health Learning Modules for Older Adults: Lessons Learned

Recently, the number of older adult online users has increased rapidly. In 2004, 22% of Americans aged 65 years or older (about 8 million) used the Internet, and 66% of them performed online searches for health information. The Web, therefore, can serve as a useful medium to educate older adults on selected health topics. In this study, the researchers developed four Web-based learning modules related to hip fracture prevention and tested the usability of these modules employing eight older adult online users. The findings from the usability tests demonstrated that the online learning modules were usable to the older adult participants. Additionally, these individuals could acquire health knowledge using these online modules. The important lessons learned through the research process will assist the researchers in conducting further studies in using health Web learning modules for older adults. A further study will be conducted to test the effects of these modules on preventing hip fractures.
Comparison of Data Quality for Reports and Ratings of Ambulatory Care by African American and White Medicare Managed Care Enrollees

Objective: Compare missing data and reliability of health care evaluations between African Americans and Whites in Medicare managed care health plans. Method: Consumer Assessment of Healthcare Providers and Systems (CAHPS) 3.0 health plan survey data collected from 109,980 Medicare managed care enrollees (101,189 Whites, 8,791 African Americans) in 321 plans. Participants self-administered the survey and four single-item global ratings of care. Results: Missing data rates were significantly higher for African Americans than Whites on all CAHPS items (p < .0001). Internal consistency reliability estimates for the CAHPS scales did not differ significantly between African Americans and Whites, but plan-level reliability estimates for the scales and global rating items were significantly lower for African Americans than Whites. Discussion: Higher missing data rates and lower plan-level reliability estimates for African American Medicare managed care enrollees suggest caution in making race/ethnicity comparisons. Future efforts are needed to enhance the quality of data collected from older African Americans.
Sufficient Conditions for Node Expansion in Bidirectional Heuristic Search

In this paper we study bidirectional state space search with consistent heuristics, with a focus on obtaining sufficient conditions for node expansion, that is, conditions characterizing nodes that must be expanded by any admissible bidirectional search algorithm. We provide such conditions for front-to-front and front-to-end bidirectional search. The sufficient conditions are used to prove that the front-to-front bidirectional search algorithm BDS1 is optimally efficient, in terms of node expansion, among a broad class of bidirectional search algorithms, for a specific class of problem instances. Dechter and Pearl's well-known result on sufficient conditions for node expansion by unidirectional algorithms such as A* is shown to be a special case of our results.

FlbC is a putative nuclear C2H2 transcription factor regulating development in Aspergillus nidulans

Asexual development (conidiation) in Aspergillus is governed by multiple regulators. Here, we characterize the upstream developmental activator FlbC in Aspergillus nidulans. flbC mRNA is detectable throughout the life cycle, at relatively high levels during vegetative growth, early asexual and late sexual developmental phases. The deletion of flbC causes a delay/reduction in conidiation, brlA and vosA expression, and conidial germination. While overexpression of flbC (OEflbC) does not elaborate conidiophores, it inhibits hyphal growth and activates expression of brlA, abaA and vosA, but not wetA. FlbC is conserved in filamentous Ascomycetes containing two C2H2 zinc fingers at the C‐terminus and a putative activation domain at the N‐terminus. FlbC localizes in the nuclei of both hyphae and developmental cells. Localization and expression of FlbC are not affected by the absence of FlbB or FlbE, and vice versa. Importantly, overexpression of flbC causes growth inhibition and activation of abaA and vosA in the absence of brlA and abaA respectively. In vitro DNA‐binding assay reveals that FlbC binds to the brlA, abaA and vosA, but not the wetA, promoters. In summary, FlbC is a putative nuclear transcription factor necessary for proper activation of conidiation, and its balanced activity is crucial for governing growth and development in A. nidulans.
Picturing the Clima(c)tic: Greenpeace and the Representational Politics of Climate Change Communication

Images of melting glaciers have come to dominate the pictorial language of climate change. This paper argues that photographs of melting glaciers engender a representational problem in the communication of climate change as they depict the already seen effects of climate change. Given the dominance of the photograph within Greenpeace campaigns, the paper examines this adherence to visual immediacy by analysing Greenpeace climate change campaign literature since 1994. Identifying five representational phases over the last decade, the analysis shows how a symbolic pictorial language of climate change was being created, and the ways in which risks were communicated as actual rather than potential. Understood retrospectively however, this visualisation calls attention to the problems of communicating environmental issues of a temporal (long term) and unseen nature through a medium of representation which privileges the ‘here and now’.
Evidence that compromised K+ spatial buffering contributes to the epileptogenic effect of mutations in the human kir4.1 gene (KCNJ10)

Mutations in the human Kir4.1 potassium channel gene (KCNJ10) are associated with epilepsy. Using a mouse model with glia‐specific deletion of Kcnj10, we have explored the mechanistic underpinning of the epilepsy phenotype. The gene deletion was shown to delay K+ clearance after synaptic activation in stratum radiatum of hippocampal slices. The activity‐dependent changes in extracellular space volume did not differ between Kcnj10 mutant and wild‐type mice, indicating that the Kcnj10 gene product Kir4.1 mediates osmotically neutral K+ clearance. Combined, our K+ and extracellular volume recordings indicate that compromised K+ spatial buffering in brain underlies the epilepsy phenotype associated with human KCNJ10 mutations. © 2011 Wiley‐Liss, Inc.
Consumption of thermally-oxidized sunflower oil by chicks reduces α-tocopherol status and increases susceptibility of tissues to lipid oxidation

The effect of heated sunflower oil consumption on α-tocopherol status, fatty acid composition and oxidative stability of chicken tissues was investigated. Chicks were fed on diets containing (g/kg): fresh sunflower oil (FSO) 40, heated sunflower oil (HSO) 40 or heated sunflower oil (40) supplemented with α-tocopheryl acetate (HSE) to a similar α-tocopherol concentration as the FSO diet. Concentrations of α-tocopherol in tissues of chicks fed on HSO and HSE were significantly lower than those of chicks fed on FSO. Significant correlations were observed between plasma α-tocopherol concentration and the α-tocopherol concentrations of other tissues (r < 0·67, P < 0·005) and between log plasma α-tocopherol and plasma thiobarbituric acid-reacting substances (TBARS) concentrations (r – 0·851, P < 0·001). The concentrations of TEARS in tissues of chicks fed on the various diets were generally very similar before stimulation of peroxidation with Fe–ascorbate. Susceptibility of tissues to Fe–ascorbate-induced lipid peroxidation was increased by feeding HSO. Supplementation with α-tocopheryl acetate reduced susceptibility tc lipid oxidation to varying degrees, depending on the tissue. The results suggest that chronic ingesrion of oxidized lipids may compromise free-radical-scavenging activity in vivo by depleting α-tocopherol in the gastrointestinal tract, or possibly in plasma and other tissues.
Making Static Figures Posable: An Interactive Figure Transformation System For Naive Users

We propose a system which can fabricate articulated figures based on static ones. We first scan the static figure to obtain a digital 3D model. The user can then insert joints to this 3D model interactively with hand gestures. Our system will then adjust the position of the joints to match the surrounding geometry and carve the collided area during the rotation inspection process. With our system, a naive user can easily convert and print out a posable, articulated figure.
A novel multi-cue based image fusion method combining multi-principle microscopy images towards Nuclear transfer technology

Since its invention, the Nuclear transfer technology has a wide range of applications in fields such as animal breeding, gene therapy, organ transplants, etc. However, since the oosight genetic material is not visible, presently the nucleus removal process of recipient oocyte always take the blind suction method, which led to extremely low success rate of nuclear transfer operation. Polarized light microscopy imaging system is very suitable for non -invasive imaging of living oocyte spindle. However, comparing to inverted microscopic imaging, it lost a lot of operating environment information (such as precision positioning of manipulation tools and cellular texture). In this paper, the advantages of polarized light microscopy imaging systems and traditional optical inverted microscope imaging system are combined. The fusion of images from polarized light microscopy imaging systems and traditional optical inverted microscope imaging system was realized. Collecting the polarized light microscopy image and inverted microscope image of same oosights in real time using two CCD cameras. A multi-cue image fusion method is proposed in this manuscript, experimental results show that this method is expected to achieve real-time visualized operation and observation.
Murine CXCR3+CD27bright NK cells resemble the human CD56bright NK‐cell population

Human NK cells can be subdivided into CD56dim and CD56bright NK cells, which exhibit different phenotypical and functional characteristics. As murine NK cells lack CD56 or a distinct correlate, direct comparative studies of NK cells in mice and humans are limited. Although CD27 is currently proposed as a feasible subset marker in mice, we assume that the usage of this marker alone is insufficient. We rather investigated the expression of the chemokine receptor CXCR3 for its suitability for distinguishing murine NK‐cell subsets with simultaneous consideration of CD27. Compared with CXCR3− NK cells, exerting stronger cytotoxic capability, CXCR3+ NK cells displayed an activated phenotype with a lower expression of Ly49 receptors, corresponding to human CD56bright NK cells. Also in common with human CD56bright NK cells, murine CXCR3+ NK cells exhibit prolific expansion as well as robust IFN‐γ, TNF‐α and MIP‐1α production. We additionally demonstrated changes in both CXCR3 and CD27 expression upon NK‐cell activation. In summary, CXCR3 serves as an additional applicable marker for improved discrimination of functionally distinct murine NK‐cell subsets that comply with those in humans.
Ventral Hernia Management: Expert Consensus Guided by Systematic Review.

OBJECTIVE To achieve consensus on the best practices in the management of ventral hernias (VH). BACKGROUND Management patterns for VH are heterogeneous, often with little supporting evidence or correlation with existing evidence. METHODS A systematic review identified the highest level of evidence available for each topic. A panel of expert hernia-surgeons was assembled. Email questionnaires, evidence review, panel discussion, and iterative voting was performed. Consensus was when all experts agreed on a management strategy. RESULTS Experts agreed that complications with VH repair (VHR) increase in obese patients (grade A), current smokers (grade A), and patients with glycosylated hemoglobin (HbA1C) ≥ 6.5% (grade B). Elective VHR was not recommended for patients with BMI ≥ 50 kg/m (grade C), current smokers (grade A), or patients with HbA1C ≥ 8.0% (grade B). Patients with BMI= 30-50 kg/m or HbA1C = 6.5-8.0% require individualized interventions to reduce surgical risk (grade C, grade B). Nonoperative management was considered to have a low-risk of short-term morbidity (grade C). Mesh reinforcement was recommended for repair of hernias ≥ 2 cm (grade A). There were several areas where high-quality data were limited, and no consensus could be reached, including mesh type, component separation technique, and management of complex patients. CONCLUSIONS Although there was consensus, supported by grade A-C evidence, on patient selection, the safety of short-term nonoperative management, and mesh reinforcement, among experts; there was limited evidence and broad variability in practice patterns in all other areas of practice. The lack of strong evidence and expert consensus on these topics has identified gaps in knowledge where there is need of further evidence.
