A Two-Phase Five-Level Converter With Least Number of Power Switches Requiring Only a Single DC Source

A novel single dc source fed five-level converter topology for medium-voltage high-power isolated grid-tied systems requiring only 12 power switches is proposed. The present configuration has two stages namely, five-level converter and the Scott-T transformer. The five-level converter stage generates only two phase voltages. Latter, these voltages are converted into three phases by using the Scott-T transformer connection. This topology requires less number of power devices and its associated gate drivers in comparison to any existing topology. In addition, the dc-link capacitors used in the topology have an ability to self-balance by themselves which eliminates the requirement of capacitor balance circuitry and complex control algorithms. The overall component count in the present configuration is very less in comparison to other topologies. Further, each device in the converter is stressed to only half of the dc-link voltage. A level-shifted carrier pulsewidth modulation scheme is adopted to control the converter, and proportional integral controllers are used to inject current into the grid at unity power factor. Theoretical analysis and simulation of the proposed converter are performed and a prototype with 1 kVA rating is validated by connecting it to a three-phase grid.
Amphibdellid (monogenean) parasites of electric rays (Torpedinidae)

Electric rays (Torpedinidae) are known to harbour on their gills certain monogenean parasites (Amphibdella spp. and Amphibdelloides spp.) whose taxonomy is in a very confused state. Muchof this confusion has centred around a single morphological feature: a ‘transverse bar’ has been variously held to be present or absent from the adhesive apparatus, or sometimes two such bars have been stated to be present. Among those who have regarded the trans-verse bar as having taxonomic importance, Price (1937) recognized two genera of amphibdellids distinguishable by the presence or absence of the bar, but Palombi (1949) and Bychowsky (1957) believe that the bar may be present in young specimens but absent or inconspicuous in older specimens. No-one has investigated the function of thistransverse bar, or, indeed, any functional aspect of the adhesive apparatus. Again little attention has been paid in taxonomy to the genitalia or host specificity, or, in spite of a record of an amphibdellid from the heart of its host, to micro-habitat.
Diamonds from Wellington, NSW: insights into the origin of eastern Australian diamonds

Abstract Diamonds from alluvial deposits near Wellington, New South Wales, have been characterized on the basis of morphological features, mineral inclusions, C isotope signatures, N content and aggregation state and internal structure. The diamonds are of two types. The larger group (Group A) is indistinguishable from diamonds found worldwide from kimberlitic and lamproitic host rocks. This group is inferred to have formed in a peridotitic mantle source in Pre-Cambrian subcratonic lithosphere. The second group (Group B) is unique in its internal structures (which show evidence of growth in a stress field and non-planar facets), has unusually heavy C isotopic compositions and contains Ca-rich eclogitic inclusions. This group is inferred to have formed in a subducting slab. Diamonds of both groups have external features (corrosion structures and polish) indicating transport to the surface by lamproitic-like magmas. The diamonds show evidence of long residence at the earth's surface and significant alluvial reworking: they are not accompanied by typical diamond indicator minerals.

Association between interleukin-1 β and epilepsy or children ’ s febrile seizures : a meta-analysis

Objective: While interleukin-1β (IL-1β) could influence the development of various diseases of the central nervous system, the conclusions are controversial in epilepsy and children’s febrile seizures. A meta-analysis was conducted to investigate the correlation between IL-1β with epilepsy or children’s febrile seizures. Methods: Pertinent studies on IL-1β and epilepsy or seizure were identified by retrieval of PubMed, EMBASE, Web of Science and EBSCO databases till June, 2016. The standard mean difference (SMD) and corresponding 95% confidence interval (CI) were to evaluate the strength of association. Results: 11 studies with a total of 247 patients and 615 controls were included in this meta-analysis. The results demonstrated that there was no difference in IL-1β level between two groups. The SMD was 0.21 (95% CI: -0.15 to 0.57, random effect model). In subgroup analysis, results were similar in child versus adult and epilepsy versus febrile seizures, with SMD 0.24 (95% CI: -0.24 to 0.72) versus 0.18 (95% CI: -0.46 to 0.82), 0.15 (95% CI: -0.37 to 0.67) versus 0.29 (95% CI: -0.27 to 0.84) respectively. In addition, among these studies, 6 evaluated the correlation between IL-6 and epilepsy and children’s febrile seizures, and the result demonstrated that higher level of IL-6 was found in these patients, the SMD were 0.68 (95% CI: 0.28-1.07, random effect model). No significant publication bias was found in the studies. Conclusions: No significance of IL-1β is found between epilepsy and febrile seizures patients and controls. However, more well-designed studies still need to be performed in the future.
Do Public Sector Contracts And Policy Towards Small Firms Matter?: Evidence From Women Business Enterprises

This paper provides an empirical investigation of the agency relationship between the public sector and small firms targeted for assistance by examining micro and macro data for a cross section of eligible women business enterprises (WBEs). Using hedonic sales and employment indices we find that 2% of firm sales is lost to negative gender externality. We show that under asymmetric information public sector transfers neither compensate for this loss of sales nor do they increase employment. When we impose transfer restrictions under perfect information, sales is unaffected but firms respond by increasing the amount of part time employees hired and do not increase full time employment. Moreover, we show that WBE presence at the state level depend on prime-contractor-sub-contractor relationships and that if long term contracts are offered then business risks are reduced and firms increase employment levels because of securitized sales. Further, formation of new WBEs are directly proportional to the amount of new small business loans provided in the economy after controlling for size and population effects. The evidence suggests that after President Richard Nixon signed Executive Order 11625 the velocity of new WBE formation is approximately 39% of the difference between policy targets and actual realization. We introduce an entrepreneurial reaction function which shows that firms react to private and public sector funding incentives but not to the level of education attainment and overall business formation in the economy. We find that agency problems provide incentives for firms to engage in strategic misrepresentation. Thus, the incidence of adverse selection in current transfer programs are as high as 60% in some instances; imposes an asymmetric residual loss on the public sector, and contrary to the goals of benevolent policy, transfers are skewed in favor of less needy firms.
End-to-End Learning of Multi-scale Convolutional Neural Network for Stereo Matching

Deep neural networks have shown excellent performance in stereo matching task. Recently CNN-based methods have shown that stereo matching can be formulated as a supervised learning task. However, less attention is paid on the fusion of contextual semantic information and details. To tackle this problem, we propose a network for disparity estimation based on abundant contextual details and semantic information, called Multi-scale Features Network (MSFNet). First, we design a new structure to encode rich semantic information and fine-grained details by fusing multi-scale features. And we combine the advantages of element-wise addition and concatenation, which is conducive to merge semantic information with details. Second, a guidance mechanism is introduced to guide the network to automatically focus more on the unreliable regions. Third, we formulate the consistency check as an error map, obtained by the low stage features with fine-grained details. Finally, we adopt the consistency checking between the left feature and the synthetic left feature to refine the initial disparity. Experiments on Scene Flow and KITTI 2015 benchmark demonstrated that the proposed method can achieve the state-of-the-art performance.
In vivo Antimutagenicity of Dadih Probiotic Bacteria towards Trp-P1

In vitro acid- and bile-tolerant lactic acid bacteria isolated and identified from Indonesian traditional fermented milk dadih might be considered as potential probiotic strains after further characterization with animal models, especially for their therapeutic properties. Five dadih lactic bacteria isolates each had moderate survival rate for 2 h at pH 2.0, as well as bile tolerance. The aim of this research was to identify candidate probiotic lactic bacteria among indigenous dadih lactic isolates originated from Bukit Tinggi, West Sumatra, especially their in vivo antimutagenic property. Milk cultured with Enterococcus faecium IS-27526 significantly lowered fecal mutagenicity of rats as compared to the control group, skim milk, and milk cultured with L. plantarum IS-20506. These results suggest that Enterococcus faecium IS-27526 may serve as a potential probiotic strain with its antimutagenicity.
Modeling Communities in e3value

Increasingly, communities play an important role in business value models. However, in e value, there seems not to be a suitable construct to model communities. In this paper, we propose an additional concept that can be used for communities, namely the "group". We illustrate the use of this concept for understanding a business model in the field of ICT4D (ICT for developing countries). abstract environment.
Building Sustainability into Services Marketing: Expanding Decision-Making from a Mix to a Matrix

The purpose of this study is to develop a framework that will provide the services marketing manager a systematic, holistic and transparent means of enhancing sustainability performance through the marketing function. We review the literature dealing with the confluence of services marketing and sustainability, identify gaps in current sustainability-services marketing literature and inductively develop a conceptual framework for Sustainability Services Marketing (SSM). We describe services marketing practice examples in order to uncover the implications of a sustainability focus for services marketing and illustrate how to operationalise the framework. The resulting framework, (i) ensures that sustainability is incorporated into the strategic services marketing planning process, (ii) adapts and expands the traditional concept of the services marketing mix, by adding Partnerships to the traditional mix elements, and (iii) cross-references services marketing mix decision-making with the triple bottom line to describe the marketing task in terms of a matrix rather than a mix. This permits sustainability benchmarking and planning across the triple bottom line, and across the range of activities the services marketing manager might be expected to manage in order to enhance sustainability performance. We shift services marketing management attention to a broader and more sustainability-responsible whole-of-business approach. This research provides timely and effective guidance for the services marketing manager seeking to enhance his or her business’s sustainability performance in a systematic, holistic, and transparent way.
Anisotropic hydrodynamics, holography, and the chiral magnetic effect

We discuss a possible dependence of the chiral magnetic effect (CME) on the elliptic flow coefficient v2. We first study this in a hydrodynamic model for a static anisotropic plasma with multiple anomalous U(1) currents. In the case of two charges, one axial and one vector, the CME formally appears as a first-order transport coefficient in the vector current. We compute this transport coefficient and show its dependence on v2. We also determine the CME-coefficient from first-order corrections to the dual AdS background using the fluid-gravity duality. For small anisotropies, we find numerical agreement with the hydrodynamic result.
Development of a High-reliability Model for Public Hospitals in Iran

Introduction: As a health care organization, achieving security and high reliability is a goal in hospitals. Therefore, this research is concerned with the development of a structural high-reliability model in public hospitals of Iran. Methodology: This applied research was conducted in 2015 with a population that included directors, managers, faculty members and hospital affairs experts. A totalof 200 questionnaires were distributed in five areas of the country based on a cluster sampling method. The structural validity of the questionnaire was approved through confirmatory factor analysis test and its reliability was calculated as 0.73 by Cronbach’s alpha test. Moreover, data were analyzed by SPSS 18 and LISREL 8.5 software using factor analysis and mathematical models; and the confirmation of the model was assessed based on confirmatory factor analysis. Findings: The results of factor analysis indicated that exploitable factors for factor analysis included selection of axis of reluctance to simplify interpretation, preoccupation with failure, sensitivity to operations, resilience and deference to expertise. Conversely, the ratio between Chi-Do index and degree offreedom was less than three, the RMSEA index was lower than 0.08, The NFI, NNFI, IFI and CFI values were higher than 0.9. Conclusions: By considering the axes of lack of tendency towards simplification of interpretations, concerns and tolerance against failure, sensitivity towards operations, flexibility and specialization hospitals will be able to achieve high-reliability criteria.
Engaging Qualities: factors affecting learner attention in online design studios

This study looks at the qualities of learner-generated online content, as rated by experts, and how these relate to learners’ engagement through comments and conversations around this content. The work uploaded to an Online Design Studio by students across a Design and Innovation Qualification was rated and analysed quantitatively using the Consensual Assessment Technique (CAT). Correlations of qualities to comments made on this content were considered and a qualitative analysis of the comments was carried out. It was observed that design students do not necessarily pay attention to the same qualities in learner-generated content that experts rate highly, except for a particular quality at the first level of study. The content that students do engage with also changes with increasing levels of study. These findings have implications for the learning design of online design courses and qualifications as well as for design institutions seeking to supplement proximate design studios with Online Social Network Services.
Novel Technique to Remove Specimen Using Capillary Action during Transurethral Resection Surgery

Purpose: Conventional methods of mechanical suction such as Ellik evacuator and Toomey syringe for clots evacuation or specimen removal with bladder retention or resected masses from endoscopic surgery has risk of bladder perforation. The purpose of this study was to devise a novel method to remove specimen easily without causing complications. Materials and Methods: Trans Urethral Resection of Bladder Tumor (TURBT) was performed for patients with bladder tumors. Resected tumor masses were removed using a novel technique with capillary action. Results: The novel technique to remove specimen involved the following five steps. First, tumor masses are resected with a resectoscope having wire loop and electro coagulation is performed for the bleeding point. Second, the valve of irrigation line is locked to prevent distention of bladder. Third, the resectoscope is taken to be close to the specimen. Fourth, the resectoscope is pulled half way back from the sheath to form capillary pressure. Fifth, specimens are spontaneously drained by capillary action. Conclusion: A novel technique to remove specimen from TURBT using capillary action without mechanical suction such as Ellik evacuator or Toomey syringe was developed. In addition to specimen removal, stone fragments and clots could be easily removed without causing complications.
Effect of freeze-drying on camel's milk nutritional properties.

The purpose of this research was to study the effect of freeze-drying process on camel’s milk nutritional characteristics compared with fresh milk. The results showed that the protein, casein, whey proteins, lactose and ash percentage were significantly higher (P< 0.05) in freeze-dried skim milk than fresh milk. The average of mineral contents in reconstituted freeze-dried skim camel’s milk was slightly higher than that of fresh camel milk except Ca, K and P contents. On the other hand, freeze-dried skim camel’s milk had a slightly higher concentration of watersoluble vitamins except vitamin C. Vitamins B, A, D and E showed relatively stable values after freeze-drying treatment. Freeze-drying process skim camel’s milk was characterized by slightly higher contents of all amino acids. Freeze-dried whole milk showed higher contribution of Protein efficiency ratio, Biological value and Net protein utilization than that of fresh whole milk. Freeze-dried process had a little effect on fatty acid profile in camel milk fat. Nutritional properties of lyophilized camel’s milk remained basically unchanged compared with fresh milk.
Managing organizational change by using soft systems thinking in action research projects

Purpose – This paper aims to show how systems thinking can be incorporated in action research (AR) interventions to successfully implement organizational change. The two case studies described in this paper would be useful to managers who want to implement change in their own organizations.Design/methodology/approach – Both projects used AR as the methodology due to its flexible, responsive and emergent nature. In one project, there was a deliberate attempt to incorporate soft systems thinking whereas in the other project soft systems thinking was used as a sense‐making process while carrying out AR. As an added benefit both approaches have resulted in successful completion of doctoral research.Findings – Soft systems methodology (SSM) and AR can both help in addressing ill‐structured problems faced by managers, in collaboration with stakeholders using questioning and reflection. Both lead to an increased understanding about the problem situation. The difference is that SSM uses a more structured approach.
Laser ablation aerosol particle time-of-flight mass spectrometer (LAAPTOF): performance, reference spectra and classification of atmospheric samples

Abstract. The laser ablation aerosol particle time-of-flight mass spectrometer (LAAPTOF, AeroMegt GmbH) is able to identify the chemical composition and mixing state of individual aerosol particles, and thus is a tool for elucidating their impacts on human health, visibility, ecosystem, and climate. The overall detection efficiency (ODE) of the instrument we use was determined to range from ∼ (0.01 ± 0.01) to ∼ (4.23 ± 2.36) % for polystyrene latex (PSL) in the size range of 200 to 2000 nm, ∼ (0.44 ± 0.19) to ∼ (6.57 ± 2.38) % for ammonium nitrate (NH4NO3), and ∼ (0.14 ± 0.02) to ∼ (1.46 ± 0.08) % for sodium chloride (NaCl) particles in the size range of 300 to 1000 nm. Reference mass spectra of 32 different particle types relevant for atmospheric aerosol (e.g. pure compounds NH4NO3, K2SO4, NaCl, oxalic acid, pinic acid, and pinonic acid; internal mixtures of e.g. salts, secondary organic aerosol, and metallic core–organic shell particles; more complex particles such as soot and dust particles) were determined. Our results show that internally mixed aerosol particles can result in spectra with new clusters of ions, rather than simply a combination of the spectra from the single components. An exemplary 1-day ambient data set was analysed by both classical fuzzy clustering and a reference-spectra-based classification method. Resulting identified particle types were generally well correlated. We show how a combination of both methods can greatly improve the interpretation of single-particle data in field measurements.
Schedule Execution Queue Occupancy 69 10 Duration Circuit Configuration Duration Circuit Configuration Leftover

Increasing pressure for higher throughput, better response times, and lower cost in datacenters have lead to proposals augmenting traditional packet networkswith very high bandwidth reconfigurable circuits. These proposals have focused on switch implementation or scheduling, not end-to-end challenges. In this work, we identify three key challenges: 1) rapid bandwidth fluctuation, 2) poor demand estimation, and 3) difficult-to-schedule workloads. Bandwidth fluctuation requires TCP to immediately jump in sending rate for <10 RTTs; poor demand estimation from shallow ToR queues leads to inefficient circuit schedules; and finally, certain application workloads are fundamentally difficult to schedule. To overcome these challenges, we build an open-source reconfigurable datacenter network emulator, Etalon, for public testbeds. We find solutions at different layers: we combat 1) bandwidth fluctuation with dynamic in-network queue resizing to ramp up TCP earlier, 2) poor demand estimation by communicating endhost stack buffer occupancy, leading to more accurate schedules, and 3) difficult-to-schedule workloads by rewriting application logic (e.g., HDFS’ write placement algorithm). We conclude that cross-layer optimization is necessary and provides the most benefit at higher layers.
