A spoke-type IPM machine with novel alternate airspace barriers and reduction of unipolar leakage flux by step-staggered rotor

This paper proposes a spoke-type IPM machine with novel alternate airspace barriers, through which higher torque capability and better manufacturability can be obtained, without remarkable deterioration in mechanical strength. Further, the influence of end leakage flux in the novel IPM design is investigated by 3-dimensional (3D) finite element (FE) method, including the leakage flux characteristics and torque capability. Furthermore, a step-staggered rotor is proposed to reduce the unipolar leakage flux and magnetization of the end shaft. As an extension, unipolar leakage flux is further investigated in consequent-pole PM machines, as well as the validity of step-staggered method. Finally, prototypes are fabricated and tested to verify the foregoing analyses, including the magnetic field at the end shaft and the output capability.
Living benthic foraminifera: biogeographical distributions and the significance of rare morphospecies

Previous studies have investigated regional distribution but this is the first attempt to investigate the global biogeographical distribution of individual morphospecies of living/stained smaller benthic foraminifera. From 8032 samples collected between 1952 and 2011 data have been gathered on the relative abundance of >120 species in five major environments ranging from marsh to deep sea. There is a spectrum of six groups of species with abundance ranging from very high (Group 1) to extremely low (Group 6). In the latter species abundance never reaches 10% of an assemblage and, in many cases, it is only 1–2%. Individual species are shown to occupy a range of environments with very few being confined to a single environment (usually either marsh or deep sea). Some species occur in several oceans while others are confined to just one. There is no correlation between species abundance and being either widely or narrowly distributed. Propagules are the most likely mechanism of dispersal but some narrowly distributed species may not produce them. Generalists may be widely or narrowly distributed but opportunists are likely to be widely distributed. The rare species of Group 6 contribute to high diversity in shelf and deep-sea assemblages. These species may be adapted to minor differences in microhabitats induced by disturbance and patchy food supply. Patterns of biogeography have application to ecology, palaeoecology and taxonomy. Supplementary Material: Taxonomy and details of types; sources of data (N1–N55) additional to that of Murray (2006); and sources of data for Figures 4–95 plus other agglutinated and hyaline taxa are available at www.geolsoc. org.uk/SUP18576
Average group effect of strongly correlated predictor variables is estimable

It is well known that individual parameters of strongly correlated predictor variables in a linear model cannot be accurately estimated by the least squares regression due to multicollinearity generated by such variables. Surprisingly, an average of these parameters can be extremely accurately estimated. We find this average and briefly discuss its applications in the least squares regression.
Wireless Vestibular Evoked Myogenic Potentials System

Vestibular Evoked Myogenic Potentials (VEMPs) is a technique that can provide useful information in diagnosing certain balance disorders. Existing commercial VEMP testing systems are cabled systems, which impede certain experiments, particularly those that involve motion and rotation of the patient. This paper presents an autonomous wireless system to record VEMPs. The system uses IMEC's 60 muW 60 nV/radicHz biopotential readout front-end to extract the electromyogram (EMG). It uses IMEC's low-power processing and wireless platform to perform all signal processing locally, significantly reducing the amount of wireless data transmission. The system also implements a low-power audio synthesizer and an amplifier to create the necessary audio or vibration stimuli that are applied to the patient. The system can perform 1000 measurements on 2 AA batteries.
Monitoring Wireless Sensor Networks Through Logical Deductive Processes

This paper proposes a distributed multi-agent architecture for wireless sensor networks management, which exploits the dynamic reasoning capabilities of the Situation Calculus in order to emulate the reactive behavior of a human expert to fault situations. The information related to network events is generated by tunable agents installed on the network nodes and is collected by a logical entity for network managing where it is merged with general domain knowledge, with the aim of identifying the root causes of faults, and deciding on reparative actions. The logical inference system has being devised to carry out automated isolation, diagnosis, and, whenever possible, repair of network anomalies, thus enhancing the reliability, performance, and security of the network. To illustrate the advantages and potential benefits deriving from the reasoning capabilities of our management system, we also discuss an application scenario concerning the need of effectively coping with congestion arising in critical parts of the network.
Bank Credit and Unemployment

The worst employment slumps tend to follow the largest expansions of household debt. In this paper, we theoretically investigate an amplification mechanism by which debt on household balance sheets distorts labor market search behavior, leading to deeper employment slumps. Using a competitive search model, we find that levered households protected by limited liability engage in risk-shifting by searching for jobs with high wages but low employment probabilities. In general equilibrium, firms respond to this household preference distortion and post high wages but few vacancies. This vacancy-posting effect implies that high household debt leads to high unemployment, a result that casts light on why labor market recoveries are sluggish after financial crises. The equilibrium level of household debt is inefficiently high due to a household-debt externality — banks fail to internalize the effect that household leverage has on employment via the vacancy-posting effect. We analyze the role that a financial regulator can play in mitigating this externality. We find that loan-to-value caps for households and capital requirements for banks can elevate employment and improve efficiency, providing an alternative to monetary policy for labor market intervention.
Crystallinity and Linear Rheological Properties of Polymers

Abstract The crystallization of a polymer melt, taking place during transformation processes, has a great impact on the process itself, mainly because it causes a large increase in the viscosity (hardening). Knowledge of the hardening kinetics is important for modeling and controlling the transformation processes. In this work, first an overview is given of the experimental and modeling work on the hardening of crystallizing polymers. Next, we present isothermal crystallization experiments using differential scanning calorimetry (DSC) and rotational rheometry to measure the dynamic viscosity. The evolution of the relative crystallinity and normalized complex viscosity are correlated by a novel technique which allows simultaneous analysis of several runs, even if they are not carried out at same temperatures; the main requirement with the traditional technique. The technique, described in detail in this paper, provides an experimental relationship between the crystallinity and the hardening, i.e. the increase in the viscosity. Moreover, by measuring the dynamic viscosity at different frequencies, surprisingly, a master curve is obtained which combines the effects of shear rate, temperature and the level of crystallinity.
Operations sequencing in a cable assembly shop

The need for a better, compact and neat solution in the cable systems used by the automotive industry resulted in emerge of companies specialized in producing such cable systems. The present study is an extension of the work that was carried out for one such company. One of the main operations in the production of cable systems is the attachment of the connectors to the ends of the cables. This process is composed of cutting, stripping and crimping the cable ends. These operations are to be performed for each connecter attachment. Each connector type requires a different head for the crimping operation. Thus, the required setup time is doubled if the heads for both ends of the cable should be changed. The problem in hand is a TSP where the distances between the nodes are either one or two. An effective and simple heuristic algorithm is developed that yields either an optimum solution or one that is off by a few percent. Among nine experiments six resulted with optimum solution while the others deviated from the optimum at most one percent.
CHEMOPREVENTIVE POTENTIAL OF DIOSGENIN ON MODULATING GLYCOPROTEINS, TCA CYCLE ENZYMES, CARBOHYDRATE METABOLISING ENZYMES AND BIOTRANSFORMATION ENZYMES AGAINST N-METHYL-N-NITROSOUREA INDUCED MAMMARY CARCINOGENESIS

Objective: Chemically induced carcinogenesis models in the rat widely used for studying the biology of cancer development and evaluating cancer prevetion strategies. The aim of our present investigation attempts to evaluate antitumourogenic efficacy of steroidal sapogenin, diosgenin against NMU induced mammary carcinoma in Sprague Dawley rats. Methods: Mammary carcinogenesis was induced by administring a single dose of (50mg/kg bodyweight) of NMU intraperitoneally. Results: Mammary cancer bearing Group II bearing experimental animals showed enzymatic alterations in the levels of (P<0.05) glycoproteins, TCA cycle enzymes, carbohydrate metabolising enzymes Kreb cycle enzymes and biotransformation enzymes. Conclusion: These biochemical modulations were reverted close to normal levels upon management of steroidal sapogenin in group III animals. From the result of our present analysis, we concluded that diosgenin have anticarcinogenic activity against NMU induced breast cancer.
Formation of HCO+ by the associative ionization of CH+O

The cross section and rate constant of the chemi-ionization reaction CH+O to HCO++e are calculated from a theoretical model. The treatment assumes that the collision partners follow classical adiabatic trajectories up to the region where the potential surfaces cross, and that either the Landau-Zener model or a unit probability gives the transition probability for curve-crossing along the single dimension defined by the trajectory. Potential surfaces were obtained from experimental data and INDO calculations. Cross sections and rates were computed for a variety of parameters, in order to test their sensitivity to the model. The process can proceed from CH+O in their ground states; of the available potential surfaces of neutral HCO, the most important is that of the 2 Sigma - state, followed by the two surfaces associated with the 2 Delta state. The cross section for the 2 Sigma - surface may be as high as 8 AA2 for collisions of very low velocity. The rate coefficient curve deemed most probable gives values of ca. 3.5*10-11 cm3 s-1 at 1000 K, and about 7*10-12 cm3 s-1 at 25 K.

SEURAT

A completed software product is the end result of many decisions that must be made throughout the development lifecycle. Unfortunately, the rationale for these decisions is usually not captured and is therefore lost. The Software Using RATionale (SEURAT) system integrates with the Eclipse Interactive Development Environment to support rationale capture and use. In addition to presenting the rationale to the developer/maintainer as needed, SEURAT also supports requirements traceability and impact assessment.
THE SUBSURFACE-SHEAR-SHAPED SOLAR αΩ DYNAMO

We propose a solar dynamo model distributed in the bulk of the convection zone with toroidal magnetic-field flux concentrated in a near-surface layer. We show that if the boundary conditions at the top of the dynamo region allow the large-scale toroidal magnetic fields to penetrate close to the surface, then the modeled butterfly diagram for the toroidal magnetic field in the upper convection zone is formed by the subsurface rotational shear layer. The model is in agreement with observed properties of the magnetic solar cycle.
Is there a relationship between haematological parameters and postoperative atrial fibrillation in off-pump or on-pump CABG patients?

The aim of our study was to assess the relationship between haematological parameters and development of post-operative AF whether off-pump or on pump CABG cohort. Between December 2011 and May 2015 a total of 346 patients undergoing CABG were analysed for our study. Preoperative MPV values were higher in AF group than those remained in sinus rhythm. Postoperative hematologic parameters showed that MPV, PDW, Lymphocyte count, N/L Ratio were also higher in AF group than those remained in sinus rhythm. In the logistic univariate regression there weren't any hematologic predictors of the development of new-onset AF. In this study, we could not find any relationship between haematological parameters and post-operative development of AF.
Southern Ocean controls of the vertical marine δ13C gradient – a modelling study

Abstract. δ13C, the standardised 13C ∕ 12C ratio expressed in per mille, is a widely used ocean tracer to study changes in ocean circulation, water mass ventilation, atmospheric pCO2, and the biological carbon pump on timescales ranging from decades to tens of millions of years. δ13C data derived from ocean sediment core analysis provide information on δ13C of dissolved inorganic carbon and the vertical δ13C gradient (i.e. Δδ13C) in past oceans. In order to correctly interpret δ13C and Δδ13C variations, a good understanding is needed of the influence from ocean circulation, air–sea gas exchange and biological productivity on these variations. The Southern Ocean is a key region for these processes, and we show here that Δδ13C in all ocean basins is sensitive to changes in the biogeochemical state of the Southern Ocean. We conduct a set of idealised sensitivity experiments with the ocean biogeochemistry general circulation model HAMOCC2s to explore the effect of biogeochemical state changes of the Southern and Global Ocean on atmospheric δ13C, pCO2, and marine δ13C and Δδ13C. The experiments cover changes in air–sea gas exchange rates, particulate organic carbon sinking rates, sea ice cover, and nutrient uptake efficiency in an unchanged ocean circulation field. Our experiments show that global mean Δδ13C varies by up to about ±0.35 ‰ around the pre-industrial model reference (1.2 ‰) in response to biogeochemical change. The amplitude of this sensitivity can be larger at smaller scales, as seen from a maximum sensitivity of about −0.6 ‰ on ocean basin scale. The ocean's oldest water (North Pacific) responds most to biological changes, the young deep water (North Atlantic) responds strongly to air–sea gas exchange changes, and the vertically well-mixed water (SO) has a low or even reversed Δδ13C sensitivity compared to the other basins. This local Δδ13C sensitivity depends on the local thermodynamic disequilibrium and the Δδ13C sensitivity to local POC export production changes. The direction of both glacial (intensification of Δδ13C) and interglacial (weakening of Δδ13C) Δδ13C change matches the direction of the sensitivity of biogeochemical processes associated with these periods. This supports the idea that biogeochemistry likely explains part of the reconstructed variations in Δδ13C, in addition to changes in ocean circulation.

The Relationship between Changes in the Economic Sentiment Indicator and Real GDP Growth: A Time-Varying Coefficient Approach

The aim of this paper is to capture the time-varying effects of the relationship between changes in the Economic Sentiment Indicator (ESI) and economic growth. We use penalized regression splines to estimate the different point effects over time. Evidence from six European countries supports the idea that the elasticity of the ESI is time-varying.
WISE DETECTIONS OF DUST IN THE HABITABLE ZONES OF PLANET-BEARING STARS

We use data from the Wide-field Infrared Survey Explorer (WISE) all-sky release to explore the incidence of warm dust in the habitable zones around exoplanet-host stars. Dust emission at 12 and/or 22 μm (Tdust ∼ 300 and/or ∼150 K) traces events in the terrestrial planet zones; its existence implies replenishment by evaporation of comets or collisions of asteroids, possibly stirred by larger planets. Of the 591 planetary systems (728 extrasolar planets) in the Exoplanet Encyclopaedia as of 2012 January 31, 350 are robustly detected by WISE at ⩾5σ level. We perform detailed photosphere subtraction using tools developed for Spitzer data and visually inspect all the WISE images to confirm bona fide point sources. We find nine planet-bearing stars show dust excess emission at 12 and/or 22 μm at ⩾3σ level around young, main-sequence, or evolved giant stars. Overall, our results yield an excess incidence of ∼2.6% for stars of all evolutionary stages, but ∼1% for planetary debris disks around main-sequence stars. Besides recovering previously known warm systems, we identify one new excess candidate around the young star UScoCTIO 108.
Postoperative pain management practices and their effectiveness after major gynecological surgery: An observational study in a tertiary care hospital

Background and Aims: Despite advances in postoperative pain management, patients continue to experience moderate to severe pain. This study was designed to assess the strategy, effectiveness, and safety of postoperative pain management in patients undergoing major gynecological surgery. Material and Methods: This observational study included postoperative patients having major gynecological surgery from February 2016 to July 2016. Data collected on a predesigned data collection sheet included patient's demographics, postoperative analgesia modality, patient satisfaction, acute pain service assessment of numeric rating scale (NRS), number of breakthrough pains, number of rescue boluses, time required for the pain relief after rescue analgesia, and any complication for 48 h. Results: Among 154 patients reviewed, postoperative analgesia was provided with patient-controlled intravenous analgesia in 91 (59.1%) patients, intravenous opioid infusion in 42 (27%), and epidural analgesia in 21 (13.6%) patients with no statistically significant difference in NRS between different analgesic modalities. On analysis of breakthrough pain, 103 (66.8%) patients experienced moderate pain at one time and 53 (51.4%) at two or more times postoperatively. There were 2 (0.6%) patients experiencing severe breakthrough pain due to gaps in service provision and inadequate patient's knowledge. Moderate-to-severe pain perception was irrespective of type of incision and surgery. Vomiting was significantly higher (P = 0.049) in patients receiving opioids. Conclusion: Adequacy of postoperative pain is not solely dependent on drugs and techniques but on the overall organization of pain services. However, incidence of nausea and vomiting was significantly higher in patients receiving opioids.
HCV Eradication with Direct-Acting Antivirals Does Not Impact HCC Progression on the Waiting List or HCC Recurrence after Liver Transplantation

Background The introduction of direct-acting antivirals (DAA) for HCV has led to high rates of HCV eradication. Treatment of patients awaiting liver transplantation (LT) has been controversial. Recent data suggests that DAA treatment may accelerate recurrent HCC. The impact of DAA on delisting for HCC progression or recurrent HCC post-LT has not been well characterized. Methods A retrospective review of both waitlist patients and LT recipients at a single institution was performed. Patient demographics, HCV treatment, HCC features and treatments, biopsy results, and graft and patient survival were evaluated. Patients on the LT waitlist or who were transplanted between January 2014 and December 2015 were included. Data was collected through December 2017 to have a minimum of two years of follow-up. Results In the study period, 128 adult LT were performed. 44 patients were HCV+, and 68.2% (N=30) also had HCC. 38.6% (N=17) of HCV+ patients received DAA pre-LT, and 94.1% (N=16/17) achieved sustained virologic response (SVR) pre-LT. Among untreated HCV+ patients who underwent LT, 81.5% (N=22/27) received DAA post-LT, with 82.6% achieving SVR post-LT (N=18/22). 82.1% (N=23/28) of untreated post-LT patients underwent liver biopsy prior to therapy, and 52.2% had at least F1 METAVIR fibrosis. 87.5% (N=14/16) of active waitlist patients received DAA and achieved SVR. HCV eradication did not result in higher rates of delisting for HCC progression. Due to local HCC listing criteria of total tumor volume and AFP, 60% (N=18/30) of HCV+/HCC patients were beyond Milan criteria at the time of LT. Despite this, there was no difference in HCC recurrence rates post-LT, whether patients achieved SVR pre- or post-LT. Conclusions These data suggest that HCV eradication pre-LT does not significantly impact waitlist time for HCV+ patients with HCC. HCV eradication does not impact rates of delisting for HCC progression or rates of HCC recurrence post-LT.
