Electromagnetic Analysis of Flux Characteristics of Double-Sided Switched Reluctance Linear Machine

This paper analyzed the flux characteristics of the double-sided switched reluctance linear machine. The magnetic equivalent circuit is given. The magnetization curves at six special mover positions are respectively calculated by the flux tube method, the magnetic flux paths distribution of air gap segments are presented, and the details of the magnetic reluctance component of each path are described. The calculated magnetization curves at six special mover positions is used as the switches for training the magnetic flux linkage model based on the BP neural networks with a GA algorithm. The mathematical mapping relationship between the mover position and the phase current to the magnetic flux linkage is established, and the magnetic flux linkage at certain mover position and certain phase current is calculated by the mathematical mapping relationship. Simulation and the experimental study with the prototype hardware are carried out on the magnetization curves at six special mover positions and three velocities of the mover. It is shown that the magnetization curves at six special mover positions calculated by magnetic equivalent circuit are consistent with the 3-D FEM calculated data and the experimental data, and the simulated phase current waveforms are also consistent with the experimental results. The magnetic equivalent circuit, the analytical calculation of the magnetization curves at six special mover positions, and the BP neural networks magnetic flux linkage model with GA algorithm are validated.
First experience with hybrid percutaneous transmyocardial laser revascularization and angioplasty in patients with lesions at high risk for restenosis: Results of a phase I feasibility study.

BACKGROUND Prior studies have suggested that percutaneous transmyocardial laser revascularization (PTMR) may be effective as a sole treatment modality in reducing angina in patients with severe coronary artery disease and no revascularization alternatives. The safety and efficacy of the hybrid or adjunctive use of PTMR during the same procedure as percutaneous intervention (PCI) has not previously been reported. METHODS A US phase I feasibility study was therefore performed to determine whether PTMR performed in the same myocardial territory as PCI is able to ameliorate symptomatic recurrence from restenosis. RESULTS After successful and uncomplicated PCI in 26 patients with class III-IV angina and lesion(s) at high risk for restenosis, PTMR was performed in the same myocardial territories subtended by the treated vessel(s). Major periprocedural adverse events (death, Q-wave myocardial infarction, and bypass surgery) occurred in 3 (11.5%) patients, as the result of subacute vessel closure in 2 patients, and tamponade in the third. Cumulative 6-month mortality rate was 19.2%, including 2 late deaths between 3 and 4 months after discharge (1 death caused by late stent closure and 1 unexplained death during sleep.) Late repeat revascularization for restenosis in the PCI plus PTMR treated target vessel was required in 19.2% of patients, and an additional 11.5% of patients had class III-IV angina at 6-month follow-up. CONCLUSIONS These data demonstrate that in a patient population at high risk for restenosis, recently created PTMR channels are not protective against severe ischemia caused by acute vessel closure and that late symptomatic restenosis after PCI may still frequently occur despite PTMR in the same region.
On the heating of linear conductive structures as guide wires and catheters in interventional MRI

The interest in performing vascular interventions under magnetic resonance (MR) guidance has initiated the evaluation of the potential hazard of long conductive wires and catheters. The objective of this work is to present a simple analytical approach to address this concern and to demonstrate the agreement with experimental results. The first hypothesis is that a long conductive structure couples with the electric field of the radio frequency (RF) transmit coil. The second hypothesis is that this coupling induces high voltages near the wire ends. These voltages can cause tissue heating due to induced currents. The experimental results show an increase in coupling when moving a guide wire toward the wall of an RF transmit coil, documented with a temperature increase of a saline solution in close proximity to the tip of the guide wire. The coupling of the wire not only presents a potential hazard to the patient, but also interferes with the visualization of the wire. A safe alternative would be the use of nonconducting guide wires.

Functions involved in bacteriophage P2-induced host cell lysis and identification of a new tail gene

Successful completion of the bacteriophage P2 lytic cycle requires phage-induced lysis of its Escherichia coli host, a process that is poorly understood. Genetic analysis of lysis-deficient mutants defined a single locus, gene K, which lies within the largest late transcription unit of P2 and maps between head gene L and tail gene R. We determined and analyzed the DNA sequence of a ca. 2.1-kb EcoRV fragment that spans the entire region from L to R, thus completing the sequence of this operon. This region contains all of the functions necessary for host cell lysis. Sequence analysis revealed five open reading frames, initially designated orf19 through orf23. All of the existing lysis mutants--ts60, am12, am76, and am218--were located in orf21, which must therefore correspond to gene K. The K gene product has extensive amino acid sequence similarity to the product of gene R of bacteriophage lambda, and its exhibits endolysin function. Site-directed mutagenesis and reverse genetics were used to create P2 amber mutants in each of the four other newly identified open reading frames. Both orf19 (gene X) and orf20 (gene Y) encode essential functions, whereas orf22 (lysA) and orf23 (lysB) are nonessential. Gene Y encodes a polypeptide with striking similarities to the family of holin proteins exemplified by gpS of phage lambda, and the Yam mutant displayed the expected properties of a holin mutant. The gene products of lysA and lysB, although nonessential, appear to play a role in the correct timing of lysis, since a lysA amber mutant caused slightly accelerated lysis and a lysB amber mutant slightly delayed lysis of nonpermissive strains. Gene X must encode a tail protein, since lysates from nonpermissive cells infected with the X amber mutant were complemented in vitro by similar lysates of cells infected with P2 head mutants but not with tail mutants.

Research on Performance Evaluation of Human Resources Management in Public Sector

Performance evaluation is one of the most important works in human resources management in public sector. In addition, performance appraisal system is a crucial evaluation criterion for organizations and employee contributions. In this paper, we analyzed the problems of human resources management performance assessment in public sector, such as lack of institutional support, immature evaluation system, lack of motivation, lack of flexibility salary system and other issues. These deficiencies seriously affected the efficiency of human resource management in the public sector. At the same time, the corresponding optimization measures and solutions are put forward, including establishing institutional foundation and optimizing social environment, improving human resources performance appraisal system, establishing a flexible compensation system and improving incentives, as well as applying performance management model based on big data.

Campylobacter pylori associated acute gastritis in a child.

The results accord with the suggestion that C pylori is able to neutralise bactericidal gastric acid very rapidly by buffering H+ ions. The rapid alkalinisation ofthe microenvironment around Cpylori seems likely to be mediated by the great amount of active urease available in the outer membrane of the bacterium. Thus urease of C pylori is a highly active enzyme that may be associated with virulence by different means: first, the urease activity protects the bacterium from the gastric acid; and secondly, the generated ammonia may then cause cytopathic effects like cell damage and possibly inflammation.5
Canadian physical therapists' interest in web-based and computer-assisted continuing education.

BACKGROUND AND PURPOSE Distance education via computer-assisted learning (CAL), including Web-based and CD-ROM learning, confers a number of advantages compared with traditional learning methods. The purposes of this study were (1) to determine the interest of Canadian physical therapists in participating in continuing education using CAL methods and (2) to determine whether interest in CAL was related to type of employment, area of practice, education, computer skill and access, and other demographic variables. SUBJECTS AND METHODS A random sample of Canadian physical therapists and all members of cardiopulmonary interest groups were surveyed. RESULTS Of 1,426 survey questionnaires mailed, 69 were returned (58 were unopened and 11 were duplicates). From the remaining 1,357 potential survey responses, 757 responses were received, for an overall response rate of 56%. Seventy-eight percent of the respondents indicated their interest in participating in CAL. Factors associated with interest in CAL included 2 or more hours of Internet access per week, Internet access at both home and work, computer skill, education level, practice area, and belonging to a cardiopulmonary interest group. DISCUSSION AND CONCLUSION The findings indicate a large positive interest in CAL. Increasing CAL continuing education opportunities could increase options for physical therapists to meet professional expectations for continuing competency.

We observed photoluminescence (PL) spectra in 735 and 535 nm region from CdTe and CdSe colloidal quantum dots (QDs) filling in the air hole of the photonic bandgap fiber (PBF). We show the PL of these QDs is efficiently transmitted in the PBF.
Otlx2,anOtx-Related Homeobox Gene Expressed in the Pituitary Gland and in a Restricted Pattern in the Forebrain

The vertebrate nervous system forms by the specification of, successively, neuroepithelial regions and cell groups. One of the proposed major histogenic steps is the subdivision of the neural tube in compartments along its caudorostral and dorsoventral axis. This event is reflected, and may be directed, by the restricted expression of many transcription factors. Here, we report on the isolation of a new homeobox gene of the paired superclass, Otlx2, whose early expression pattern in the mesencephalon and prosencephalon is congruent with proposed neuromeric models of brain morphogenesis. In addition, its late embryonic and postnatal expression, in clear continuity with the earlier pattern, suggests a role in the neuronal differentiation and the histogenesis of several prosencephalic and mesencephalic areas. Finally, Otlx2 is expressed from the earliest morphogenetic events in the Rathke's pouch, the anlage of the adenohypophysis, an expression site shared by a very close homologue, Otlx1/Ptx1/P-Otx.
Methylcyclopentanoid Monoterpenes Mediate Interactions Among Insect Herbivores

Beetles secrete an array of chemicals generally believed to mitigate attack by predators. Methylcyclopentanoid monoterpenes secreted by larvae of the willow leaf beetle, Plagiodera versicolora, deter feeding by conspecific adults. Furthermore, the secretion elicits a strong repugnancy response in larvae of another willow herbivore, Nymphalis antiopa. Leaves bearing beetle larvae are less likely than leaves not bearing beetles to be frequented and consumed by Nymphalis larvae. Predator defense may not be the sole function of glandular secretions produced by herbivorous insects; secretions may also mediate interactions among herbivores that use a common resource.
Climate Change Adaptation In Serbia: The Role Of Information Networks

Facing climate shift and responding to its challenges have become important concerns for scientists, politicians and grassroots movements in their efforts to reduce the carbon footprint. Simultaneously, they all agree that information has a significant role in the process of mitigation and adaptation, especially in urban areas. Communicating the climate change and raising the general awareness are preconditions for implementation of numerous suggested measures, while detecting the condition and increasing the efficiency and low-carbon potential have become imperatives for humanity. Consequently, all these tendencies directly influence changes is spatial and activity patterns, reinforcing the material realm with information flows. The integral approach to urban development, anticipated as a preferred option for the climate-friendly future, has recently generated a number of creative concepts, tools and methods as a multi-disciplinary synergic response to accumulating problems. However, its real-time success greatly depends on the expansion and improvement of material and digital information networks because they represent a key-ingredient of all futuristic visions. Considering the current condition of climate awareness, as well as the course of undertaken actions, this article will focus on the relationship between cities, climate change and information networks, analyzing emerging ideas and innovations related to the (un)conventional use of information flows in reducing the consequences of climate change. The strategic role of networks in the exchange of data and knowledge will be examined on two levels - in the domain of public communication of climate changes, and on the level of urban systems, their effectiveness, accessibility and low-carbon outcomes. In accordance with recent environmental and technological trends, the article indentifies three areas of networks applicability, targeting main challenges of the anticipated climate-friendly development - human behavior, ecological awareness and general efficiency.
Translation and cross-cultural adaptation of a mental health battery in an African setting.

BACKGROUND Standardised measuring instruments are increasingly used in psychiatric research cross-culturally. These instruments are considered to be culturally equivalent when all forms of biases, or social norms specific to the culture of origin, have been removed. OBJECTIVES To describe the qualitative process of selection, translation and cultural adaptation of a mental health battery for use in a Xhosa-speaking community that is, as far as possible, 'culture-free' or equivalent. METHOD Informal discussions were held with key members in the community to determine what would be considered as appropriate for the community in respect of psychiatric screening instruments. Existing rating-scales for depression, alcohol abuse and posttraumatic stress disorder that would meet these criteria were identified and then translated from English into Xhosa. Cultural equivalence was achieved by combining methods of back-translation, committee consensus approach and decentering. Discussions during the committee consensus meetings were recorded and categorized into themes. Two themes emerged: (1) issues related to the attainment of semantic equivalence and (2) broader problems inherent in cross-cultural research. RESULTS Issues related to individual questionnaires included the use of terms to describe emotional distress cross-culturally. Broader issues related to the translation process itself included the form of language to be used, time-frames, and the use of Likert-scales. It also demonstrated the problems inherent in the categorization of emotions. CONCLUSION A method of combining a group approach, back-translation, and decentering was effective and efficient in this context for establishing content and semantic equivalence. Cross-cultural adaptation can never completely remove all forms of bias from a research instrument, but such limitations should be acknowledged and openly discussed, rather than hidden or ignored.
Sperm Production Rates, Sperm Physiology and Fertility in Rats Chronically Treated with Sublethal Doses of Aflatoxin B1

Rats chronically treated with sublethal doses of anatoxin B1 suffered severe testicular degeneration and impaired spermatocytogenesis with a concomitant drop in the rate and efficiency of spermatozoal production. Although the major part of sperm maturation was disturbed, there was no noticeable reduction in the viability of spermatozoa in storage, hence a fairly high degree of fertilisation occurred. That the treatment made the uterine environment less compatible with normal foetal development was demonstrated by the smaller litter size and higher embryo mortality.

Stabilization of LTI systems with periodic communication constraints by using LQR method

This paper deals with the stabilization of a networked control system (NCS) whose sensors and actuators exchange information with a controller through a shared communication medium. To control a linear time-invariant (LTI) discrete-time plant via a bus with limited capacity, we introduce a holder and a communication sequence which follows a given ω-periodic pattern. In the previous paper, we have shown that controllability and stabilizability of the plant are preserved in NCS. Moreover, we have shown that reconstructibility and detectability of the plant are preserved in NCS. In this paper, on the basis of reconstructibility and detectability, we design a middle order periodic observer and periodic state feedback by the periodic LQR method and show the validity of our proposed method by simulation.
Design and Analysis of an Energy-Saving Distributed MAC Mechanism for Wireless Body Sensor Networks

The fact that the IEEE 802.15. 4 MAC does not fully satisfy the strict wireless body sensor network (BSN) requirements in healthcare systems highlights the need for the design and analysis of new scalable MAC solutions, which guarantee low power consumption to all specific sorts of body sensors and traffic loads. While taking the challenging healthcare requirements into account, this paper aims for the study of energy consumption in BSN scenarios. For that purpose, the IEEE 802.15. 4 MAC limitations are first examined, and other potential MAC layer alternatives are further explored. Our intent is to introduce energy-aware radio activation polices into a high-performance distributed queuing medium access control (DQ-MAC) protocol and evaluate its energy-saving achievements, as a function of the network load and the packet length. To do so, a fundamental energy-efficiency theoretical analysis for DQ-MAC protocols is hereby for the first time provided. By means of computer simulations, its performance is validated using IEEE 802.15. 4 MAC system parameters.
Tumor Marker–Guided PET in Breast Cancer Patients—A Recipe for a Perfect Wedding: A Systematic Literature Review and Meta-Analysis

Introduction: Early detection of breast cancer (BC) recurrence is a fundamental issue during follow-up. Although the utilization of new therapeutic protocols aimed at reducing the recurrence risk is defined, the diagnostic approach for early detection remains to be clarified. We aim to provide a critical overview of recently published reports and perform a meta-analysis on the use of tumor markers in BC patients as a guide for fluorodeoxyglucose positron emission tomography (PET) imaging. Methods: Medline and Google Scholar were used for searching English and non-English articles that evaluate the role of PET in BC recurrence when an increase in tumor markers is found. All complete studies were reviewed; thus, quantitative and qualitative analyses were performed. Results: From 2001 to May 2011, we found 19 complete articles that critically evaluated the role of PET in BC recurrence detection in the presence of elevated tumor markers. The meta-analysis of the 13 studies provided the following results: pooled sensitivity 0.878 (95% CI: 0.838–0.909), pooled specificity 0.693 (95% CI: 0.553–0.805), and pooled accuracy 0.828 (95% CI: 0.762–0.878). Conclusions: The current experience confirms the potential of fluorodeoxyglucose PET, and in particular of PET/CT, in detecting occult soft tissue and bone metastases in the presence of a progressive increase of serum tumor markers in BC patients, but this should be better defined in the current practical recommendations.
