An integral method combining V/Hz and vector control of permanent magnet motor

This paper presents an original method for sensorless speed control of Permanent Magnet Motors (PMM). The proposed method is robust to parameter variations, does not require a starting sequence and shows good performance at low and high speeds operation. The benefits mentioned above are achieved by combining features of volts per hertz and vector control methods. The proposed method uses the q axis current regulator to estimate the angular speed of the PMM instead of providing the q axis voltage command for the inverter as is done in traditional motor control methods. The q axis voltage inverter command is calculated from q axis and d axis current references and motor parameters similar to V/Hz control method. An observer performs the estimation of q and d axis rotor fluxes, from measured and reference currents and voltages. The observer estimates are crucial for flux and consequently voltage estimation and robust operation of the method. In addition, the d axis current regulator performance is enhanced, with a feed-forward voltage signal calculated from motor parameters. The analysis presented in this paper, shows that error in the alignment with rotor flux position is proportional to the estimated rotor flux in q axis which was consequently used for rotor angle alignment.
Financial Pressures in the UK Household Sector: Evidence from the British Household Panel Survey

Household indebtedness has risen rapidly in relation to incomes in recent years. But aggregate data cannot indicate which types of households - by age, income or wealth - have accumulated the most debts. This article uses information from the latest British Household Panel Survey (for the year 2000) to provide some evidence on that issue. The survey suggests that debt-to-income ratios vary widely across households. The youngest and lowest-income households increased their debt-to-income ratios by most - and from the highest levels - between 1995 and 2000. But the households with the highest absolute levels of debts tended also to have the highest incomes and net wealth in both years. A large proportion of this wealth was held in housing assets. Such households did not, however, hold substantially more liquid assets than less indebted households. Although households were relatively sanguine about their higher levels of debt, that confidence could be eroded if circumstances deteriorated. Overall, changes in the distribution of household debt in recent years suggest that the household sector may be somewhat more vulnerable to an adverse shock than the aggregate measures indicate.
Living quarters of a living fossil—Uncovering the current distribution pattern of the rediscovered Hula painted frog (Latonia nigriventer) using environmental DNA

One of the greatest challenges of effective conservation measures is the correct identification of sites where rare and elusive organisms reside. The recently rediscovered Hula painted frog (Latonia nigriventer) has not been seen for many decades and was therefore categorized extinct. Since its rediscovery in 2011, individuals from the critically endangered species have been found, with great effort, only in four restricted sites. We applied the environmental DNA (eDNA) approach to search for new populations of the Hula painted frog in suitable aquatic habitats. We further used the eDNA data to classify the landscape factors associated with the species distribution and to predict its suitable habitats. We sampled 52 aquatic sites in the Hula Valley during the spring of 2015 and 2016 and amplified the samples with a species‐specific qPCR assay. DNA of the Hula painted frog was detected in 22 of the sites, all of which clustered within three main areas. A boosting classification model showed that soil type, vegetation cover and the current and former habitats are all key predictors of the frog's current distribution. Intriguingly, the habitat suitability models reveal a high affinity of the species to its long‐lost habitat of the historical wetlands. Our findings encourage a series of informed searches for new populations of this threatened frog and provide guidance for future conservation management programmes. In the era of global conservation crisis of amphibians, developing the eDNA approach, a reliable detection method for many critically endangered and elusive amphibians, is of particular importance.
Teaching a Machine to Feel Postoperative Pain: Combining High-Dimensional Clinical Data with Machine Learning Algorithms to Forecast Acute Postoperative Pain.

BACKGROUND Given their ability to process highly dimensional datasets with hundreds of variables, machine learning algorithms may offer one solution to the vexing challenge of predicting postoperative pain. METHODS Here, we report on the application of machine learning algorithms to predict postoperative pain outcomes in a retrospective cohort of 8,071 surgical patients using 796 clinical variables. Five algorithms were compared in terms of their ability to forecast moderate to severe postoperative pain: Least Absolute Shrinkage and Selection Operator (LASSO), gradient-boosted decision tree, support vector machine, neural network, and k-nearest neighbor (k-NN), with logistic regression included for baseline comparison. RESULTS In forecasting moderate to severe postoperative pain for postoperative day (POD) 1, the LASSO algorithm, using all 796 variables, had the highest accuracy with an area under the receiver-operating curve (ROC) of 0.704. Next, the gradient-boosted decision tree had an ROC of 0.665 and the k-NN algorithm had an ROC of 0.643. For POD 3, the LASSO algorithm, using all variables, again had the highest accuracy, with an ROC of 0.727. Logistic regression had a lower ROC of 0.5 for predicting pain outcomes on POD 1 and 3. CONCLUSIONS Machine learning algorithms, when combined with complex and heterogeneous data from electronic medical record systems, can forecast acute postoperative pain outcomes with accuracies similar to methods that rely only on variables specifically collected for pain outcome prediction.
Perioperative low-dose ketamine improves postoperative analgesia following Cesarean delivery with general anesthesia

Abstract Objective: In this study, the effect of perioperative uses of low dose ketamine on post-operative wound pain and analgesic consumption in patients undergoing elective Cesarean section was evaluated. Methods: In randomized, double blind clinical trial, 52 women with American Society of Anesthesiologists (ASA) class I-II identification undergoing elective Cesarean section in general anesthesia were enrolled. In the ketamine group (group K), a ketamine bolus of 0.5 mg kg−1 IV was administered at the time of induction of general anesthesia. After induction, a ketamine infusion of 0.25 mg kg−1 h−1 was started and discontinued at the end of surgery. Patients allocated to the control group (group C) were given identical volumes of saline. The cumulative dose of morphine consumption after surgery was measured as the primary outcome of this study. Secondary outcomes were pain control assessed by numeric rating scale (NRS) and need for rescue analgesia and incidence of side effects. Results: The mean 24-h morphine consumption was lower in group K (p = 0,001). At 15 min postoperatively, NRS values were lower in group K than group C (p = 0,001). There was no difference among groups regarding the need for supplemental analgesia (rescue diclofenac doses) (p > 0.05). Conclusions: Perioperative uses of low dose ketamine decreased post-operative opioid requirements, which was observed long after the normal expected duration of ketamine.
Why Is the U.S. Current Account Deficit So Large? Evidence from Vector Autoregressions*

Most observers consider large U.S. current account deficits to have been the main contributor to world macroeconomic imbalance in the 1980s. The implications of continuing U.S. current account deficits of 100 to 200 billion dollars per year are troubling. Other countries must adjust to the scarcity of capital as the United States acquires a significant portion of the world's savings. At the same time U.S. companies seek protection from "unfair" foreign competition as foreign companies increase market share in the United States. Determining the source of the problem, and designing the correct solution, are therefore major objectives of economic research. Policymakers and economists have suggested a number of reasons for the sudden jump in the current account deficit. Different schools of thought have therefore proposed different policy responses, ranging from doing nothing to radically altering the country's commercial policy. Debate has centered on the proposed policies, with little attention paid to comparing the explanatory power of the underlying hypotheses.
Increasing the Solubility and Recovery of Ara h3 Allergen from Raw and Roasted Peanut

Ara h3 belongs to the glycinin family of seed storage proteins and is one of the major peanut allergens. It comprises over 20% of the total peanut protein mass, making it a logical target for the detection of trace quantities of undeclared peanut contamination in foods. Both Ara h1 and Ara h3 are detected in lower quantities in cooked foods, either because of the failure to completely resolubilize the denatured proteins or because of the disruption of conformational epitopes required for monoclonal antibody recognition. A new reagent containing a proprietary non-detergent sulfobetaine (NDSB) is described which solubilizes more total protein and yields more Ara h3 protein from both raw and roasted peanut than other commonly used ELISA-compatible reagents.
Single nucleotide variant sequencing errors in whole exome sequencing using the Ion Proton System

Errors in sequencing are a major obstacle in the interpretation of next-generation sequencing (NGS) results. In the present study, sequencing errors identified from analysis of single nucleotide variants (SNVs) identified during exome sequencing of human germline DNA were studied using the Thermo Fisher Ion Proton System. Two consanguineous cases were selected for sequencing using the AmpliSeq Exome capture kit, and SNVs found in both cases were validated using Sanger sequencing. A total of 98 SNVs detected by NGS were randomly selected for further analysis. Nine of the analyzed SNVs were shown to be false positives when confirmed by Sanger sequencing. All but one SNV were considered to be homopolymer regions, mainly through the insertion or deletion of nucleotides. The remaining error was considered to be related to the primer. The present results revealed that the majority of the SNV sequencing errors originated from homopolymer insertion/deletion errors, which are commonly observed when using the Ion Torrent system.
Available bit rate (ABR) source control and delay estimation

The problem of regulating the transmission rate of an available bit rate (ABR) traffic source in an ATM network is examined. Of particular interest is linear quadratic (LQ) rate regulation based on estimates of the round-trip propagation delay. The round-trip delay is estimated using a nonlinear least mean square (NLMS) algorithm. Simulation results are used to demonstrate the method.
NUTZUNG UND BEWERTUNG DES WOHNUMFELDES IN GROSSWOHNSIEDLUNGEN AM BEISPIEL DER NACHBARSCHAFTEN U UND P IN NUERNBERG-LANGWASSER

Die Untersuchung vergleicht an zwei unterschiedlich erschlossenen Teilgebieten der Grosswohnsiedlung Nuernberg-Langwasser, ob durch das jeweils gewaehlte Erschliessungs- und Gestaltungsprinzip der Siedlung ein erhoehter Erlebniswert und groessere Aneignungsmoeglichkeiten des Wohnumfeldes, insbesondere fuer Kinder gegeben sind. Eine die beiden Gebiete trennende Schnellstrasse mit U-Bahntrasse bildet die aeussere Erschliessung und die Anbindung der Siedlungen an die Innenstadt. Gebiet P ist nur durch Fussgaengerstrassen erschlossen und hat 3.180 Einwohner, Gebiet U ist herkoemmlich erschlossen und hat 3.445 Einwohner. Dazu werden Befragungen, Erhebungen und Beobachtungen durchgefuehrt sowie vorhandene Untersuchungen und Daten ausgewertet. Dabei konnte festgestellt werden, dass im Gebiet P mit Fussgaengerstrassenerschliessung auch unter Beruecksichtigung der unterschiedlichen Altersstruktur vor allem Kinder im Alter von 3-6 Jahren deutlich staerker in Erscheinung treten und sich haeufiger ohne Begleitung Erwachsener im Wohnumfeld aufhalten; auch verlassen die Kinder im Gebiet P mit durchschnittlich 3,8 Jahren signifikant frueher allein das Haus als im Gebiet U mit 5,6 Jahren. Insgesamt kommt die Untersuchung zu dem Schluss, dass die gewaehlte Erschliessungsform (Fussgaengerstrassen im Innern des Gebietes, Stellplaetze am Rand, Wege dorthin zum Teil ueberdacht) sich bewaehrt hat. Allerdings sollte die Distanz zwischen Stellplatz und Wohnung 200 m nicht ueberschreiten. Verlaessliche Aussagen ueber eine unterschiedliche Verkehrsmittelnutzung konnten aufgrund der Vielzahl von sich zum Teil aufhebenden Einflussgroessen nicht getroffen werden, da im Rahmen der Diplomarbeit dazu nicht ausreichend viele Befragungen durchgefuehrt werden konnten.
Rate of Oxygen Consumption in Seasonal and Non-Seasonal Depression

Summary: Most depressives suffer from weight loss, anorexia and insomnia, while for winter depressives the typical symptoms are weight gain, carbohydrate craving, overeating, oversleeping and extreme lack of energy. It is important to know whether winter depressives differ from most other depressives on measures of energy regulation. In wintertime, we evaluated the rate of oxygen consumption in relationship to neuro-vegetative depressive symptoms in 92 Siberian women. The seated subjects underwent oxyspirography in the mid-morning (1.5 hours after a standard breakfast). It was found that the oxygen consumption rate was similar in non-depressed women (n = 25) and depressed women with non-seasonal depression (n = 27). The comparatively lower values were obtained in women with winter depression (n = 40). This finding supports the suggestion that the behaviour disturbances typical for winter depression may represent a physiological feedback loop to energy conservation.
If We Give a Workshop and Nobody Comes, is it still Professional Development?

This practitioner-focused paper is about an example of professional development failure in teacher education. We detail the real-life journey of the educational technology program during the 2013/14 school year in which training was planned to assist education faculty in the use of technology in their courses. This presentation outlines the hopes, the reality, lessons learned, and how failure can inform practice.
Identification of genes encoding putative nucleoporins and transport factors in the fission yeast Schizosaccharomyces pombe: a deletion analysis

In a systematic approach to study genes that are related to nucleocytoplasmic trafficking in the fission yeast Schizosaccharomyces pombe, the open reading frames (ORFs) of 26 putative nucleoporins and transport factors were deleted. Here we report the initial characterization of these deletion mutants. Of the 26 putative genes deleted, 14 were found to be essential for viability. Null mutations of essential genes resulted in failure to either complete one round or to sustain cell division. Four of the 14 essential genes, SPBC582.11c, SPBC17G9.04c, SPBC3B9.16c and SPCC162.08c, encode putative nucleoporins and a myosin‐like protein with homologues NUP84, NUP85, NUP120 and MLP1, respectively, that are not required for viability in Saccharomyces cerevisiae, suggesting that their gene products perform critical functions in Sz. pombe. On the basis of combined drug sensitivity assays and genetic analysis we have identified five non‐essential null mutants that were hypersensitive to the microtubule depolymerizing drug thiabendazole (TBZ) and exhibited a cut phenotype upon TBZ treatment, suggesting possible involvement in microtubule function. Three of the corresponding ORFs, SPCC18B5.07c, nup40 and SPAC1805.04, encode putative nucleoporins with low similarity to the S. cerevisiae nucleoporins NUP2p, NUP53p and NUP133p, respectively. Further genetic analysis revealed that one of the nucleoporin genes, nup40, and another gene, SPCC1322.06, encoding a putative importin‐β/Cse1p superfamily protein may have a spindle checkpoint function.

Computer support for transcribing recorded activity

For many researchers studying human activity, the diverse media and technologies used for recording, viewing and analysis place heavy demands on analysts who want to stay "close" to their primary data. At the same time, the analyses themselves can require very different representational media, posing difficulties for researchers wanting to juxtapose and compare multiple perspectives on their work. The tool described here is intended to address some of these issues by providing an extensible computer environment in which multiple chronologically organized representations of a single sequence of activity can be edited, juxtaposed, and aligned.
Direct evidence for tonic sympathetic support of resting metabolic rate in healthy adult humans.

The sympathetic nervous system (SNS) plays an important role in the regulation of energy expenditure. However, whether tonic SNS activity contributes to resting metabolic rate (RMR) in healthy adult humans is controversial, with the majority of studies showing no effect. We hypothesized that an intravenous propranolol infusion designed to achieve complete beta-adrenergic blockade would result in a significant acute decrease in RMR in healthy adults. RMR (ventilated hood, indirect calorimetry) was measured in 29 healthy adults (15 males, 14 females) before and during complete beta-adrenergic blockade documented by plasma propranolol concentrations > or =100 ng/ml, lack of heart rate response to isoproterenol, and a plateau in RMR with increased doses of propranolol. Propranolol infusion evoked an acute decrease in RMR (-71 +/- 11 kcal/day; -5 +/- 0.7%, P < 0.0001), whereas RMR was unchanged from baseline levels during a saline control infusion (P > 0.05). The response to propranolol differed from the response to saline control (P < 0.01). The absolute and percent decreases in RMR with propranolol were modestly related to baseline plasma concentration of norepinephrine (r = 0.38, P = 0.05; r = 0.44, P = 0.02, respectively). These findings provide direct evidence for the concept of tonic sympathetic beta-adrenergic support of RMR in healthy nonobese adults.
A novel design of microstrip squre patch filter

A novel microstrip square patch filter is proposed in this paper. The perturbation source is constructed by cutting square-hole on the patch. By analyzing the relationship between the resonant frequency and perturbation size, further put forward a novel broadband filter. For the experimental test results show that these two novel filters both have good transmission characteristics.
Trade-off shapes diversity in eco-evolutionary dynamics

We introduce an Interaction and Trade-off based Eco-Evolutionary Model (ITEEM), in which species are competing for resources in a well-mixed system, and their evolution in interaction trait space is subject to a life-history trade-off between replication rate and competitive ability. We demonstrate that the strength of the trade-off has a fundamental impact on eco-evolutionary dynamics, as it imposes four phases of diversity, including a sharp phase transition. Despite its minimalism, ITEEM produces without further ad hoc features a remarkable range of observed patterns of eco-evolutionary dynamics. Most notably we find self-organization towards structured communities with high and sustainable diversity, in which competing species form interaction cycles similar to rock-paper-scissors games.
Clustering of DNA microarray temporal data based on the autoregressive model

In this paper, we propose to combine linear prediction coefficients from the autoregressive model (AR) and the time series itself as features for the clustering algorithm. The purpose of the use of the AR model is to realize the importance of dynamic modeling of microarray time series data. We define the distance among the time series profiles using the autoregressive model and use the hierarchical clustering and the k-means clustering methods for comparison. The results show that the performance of the clustering DNA microarray time course profile is increased with the linear prediction coefficients in addition to the time series itself used as features.
Personal Healthcare Record Integration Method Based on Linked Data Model

With the increasing applications of electronic medical record systems, many hospitals have accumulated rich clinic data in format of distribution and heterogeneity. It is difficult for historic electronic medical records to be integrated from different data resources to build an overall personal electronic healthcare record (EHR) for a doctor to assess the health condition of a patient. In order to efficiently fulfill HER integrating, in this paper, Linked Data Model is extended and used to design a method for personal electronic medical data searching and integration. At first, the clinic data are obtained from transaction databases of hospital information systems, transformed and re-organized to Linked-Data format. Then data definitions are extracted from these linked electronic medical records and aligned with other open linked data resources to annotate themselves semantically for further integration. Finally, personal electronic healthcare records are constructed through linked information net. The prototype demonstrates that the proposed method is effective and efficient.
Antiproliferative effect of benzophenones and their influence on cathepsin activity

The antiproliferative activity of two prenylated benzophenones isolated from Rheedia brasiliensis, the triprenylated garciniaphenone and the tetraprenylated benzophenone 7‐epiclusianone, was investigated against human cancer cell lines. The antiproliferative activity on melanoma (UACC‐62), breast (MCF‐7), drug‐resistant breast (NCI‐ADR), lung/non‐small cells (NCI460), ovarian (OVCAR 03), prostate (PC03), kidney (786‐0), lung (NCI‐460) and tongue (CRL‐1624 and CRL‐1623) cancer cells was determined using spectrophotometric quantification of the cellular protein content. The effect of these benzophenones on the activity of cathepsins B and G was also investigated. Garciniaphenone displayed cytostatic activity in all cell lines, whereas 7‐epiclusianone showed a dose‐dependent cytotoxic effect. The IC50 values for cell proliferation revealed that 7‐epiclusianone is more active than garciniaphenone against most of the cell lines. Furthermore, the antiproliferative effects demonstrated by garciniaphenone and 7‐epiclusianone were related to their cathepsin inhibiting properties. In conclusion, 7‐epiclusianone is a promising naturally occurring agent which displays multiple inhibitory effects which may be working in concert to inhibit cancer cell proliferation in vitro. The putative pathway by which 7‐epiclusianone affects cancer cell development may involve cathepsin inhibition. Copyright © 2009 John Wiley & Sons, Ltd.
An investigation of energy efficiency in 5G wireless networks

In next generation wireless networks along with the overwhelming demand of high data rate and network capacity, the user demands ubiquitous connectivity with the network. In order to fulfill the demand of anywhere at any time data services, the network operators have to install more and more base stations that eventually leads towards high power consumption. For this, the potential solution is derived from 5G network that proposes a heterogeneous environment of wireless access networks. More particularly, deployment of Femto and Pico cell under the umbrella of Macro cell base stations (BS). Such networking strategy will result high network capacity and energy efficiency along with better network coverage. In this article, an analysis of energy efficiency has been carried out by using two-tier and three tier network configurations. The simulation results demonstrate that rational deployment of small cells improves the energy efficiency of wireless network.
