Study on a Long Primary Flux-Switching Permanent Magnet Linear Motor for Electromagnetic Launch Systems

Based on the principle of rotational flux-switching permanent magnet machines, a novel double-sided long primary flux-switching permanent magnet linear motor (FSPMLM) is proposed for electromagnetic launch systems (EMLS). Compared with traditional induction and synchronous linear machines used in EMLS, the proposed motor is more suitable for EMLS because of its high thrust density and simple structure of the secondary. First, the structure and operation principle of the proposed FSPMLM are given and analyzed. Second, considering the longitudinal end effect, the thrust components are analyzed and derived. According to the generation principle of the thrust components, the optimal methods, implemented to reduce the thrust ripple, are obtained and analyzed. In addition, a 2-D transient finite element method is used to investigate the dynamic electromagnetic characteristics of the FSPMLM and the process of electromagnetic launch. Finally, a prototype of single-sided FSPMLM is employed to validate the thrust performance of the proposed machine.
Output feedback adaptive dynamic surface control for a class of uncertain nonlinear systems

In this paper, an adaptive output feedback controller was developed for a class of nonlinear systems with unkonwn parameters, uncertain disturbances and unmeasured states. Firstly estimated states was obtained by introducing an observer. Then a controller was developed based on the dynamic surface control approach. Explosion of terms can be avoided because this method no longer needs the repeated differentiations of the virtue control. Only two parameters instead of all the neural networks weights need to be updated. All the signals of closed-loop systems can be guaranteed semiglobally uniformly ultimately bounded through the analysis of this method. The tracking error can be arbitrarily small by choosing the proper design parameters. Simulation studies show the effectiveness of the proposed approach.
The Trigonometric Interpolation Method Based on Bordering Functions in Monitoring of Wave and Resonance Changes of Mechanical and Physical Fields

The analysis of applied approaches of fast interpolation, recovery of discrete signals in multi-speed microprocessor systems for modeling and recognition of wave and resonance changes of mechanical and physical fields are given. A method of fast trigonometric interpolation based on bordering functions, which simplifies and accelerates the process of hierarchical recovery of signals is proposed. Expressions for simultaneous fast parallel filtering and interpolation of signals based on the application of new border-filtering functions are given. A set of interconnected sampling theorems for cases of equidistant and not equidistant samples of signal in time on a finite and infinite interval is formulated. The hierarchy of these theorems is determined and their interrelation with the well-known Kotelnikov's theorem is established.
Technology, Firm Size, and Safety: Theory and Empirical Evidence from the US Motor-carrier Industry

The purpose of this paper is to examine the relationship between motor-carrier firm size and safety outcomes. Leveraging insights from the resource-based view of the firm, we develop hypotheses regarding this important relationship. To test our hypotheses, we constructed an original commercial motor-carrier safety database, drawing on data from the Motor Carrier Management Information System and the Safety Measurement System. The results demonstrate that there is a significant and positive relationship between firm size and safety performance as measured through a carrier’s number of crashes, unsafe driving violations, hours-of-service compliance, and vehicle maintenance violations. The impact of firm size on safety performance varies according to industry segment. This study has important academic and public policy implications.
The effect of buyers and sellers on fish market prices

This paper extends the traditional hedonic price specification to take into account the unobserved heterogeneity of sellers, buyers and seller–buyer matches. The specification is estimated using econometric techniques for non-nested panel data models on a data set of nearly 15 million transactions occurring in French wholesale fish markets over the 2002–2007 period. Results show that unobserved heterogeneity plays a significant role in price setting. For some species, its inclusion in price regressions changes the coefficients of quality-related fish characteristics. Fish characteristics are the main factors explaining price variations for many species, but time and buyer effects also play a significant role.
Putative intermediate precursor between hematogenic endothelial cells and blood cells in the developing embryo

During embryogenesis, endothelial cells are a source of hematopoietic cells. Vascular endothelial (VE)‐cadherin modulates adherens junctions between endothelial cells. How endothelial cells, integrated into the vascular bed via adherens junctions, give rise to free‐floating hematopoietic cells has been examined. Contrary to our previous reports, in this report a cell type simultaneously expressing VE‐cadherin and the hematopoietic marker CD45 was identified, without rigorous enzymatic dissociation of embryonic tissues. In spite of expressing several other endothelial markers such as endothelial cell nitrous oxide synthase (ECNOS) and MECA‐32, this newly defined population failed to produce endothelial colonies when cultured on OP9 stroma, in direct contrast to enzymatically dissociated VE‐cadherin+ cells. When isolated from 9.5 days post coitus (d.p.c.) embryos, VE‐cadherin+ CD45+ cells generated erythroid, myeloid, but not B lymphoid, cells, also in contrast to VE‐cadherin+ cells obtained by enzymatic dissociation. Runx1 null mutant embryos lacked this novel population. Collectively, these results introduce a novel VE‐cadherin+ population within the developing embryo, which may represent an intermediate cell type in the transition of hemogenic endothelial cells into blood.
Adrenergic Receptors in Depression

Summary Platelet α2-and lymphocyte ß2-adrenoceptor densities, plasma noradrenaline and serum Cortisol were measured before, during and one week after a course of EEG-monitored electroconvulsive therapy, in nine depressed patients. A 50% fall in Hamilton Depression Rating scores occurred after a fairly consistent total seizure time, regardless of the amount of ECT given. Platelet α2-adrenoceptor densities showed a statistically significant fall after three ECTs, but were unchanged after the full course of ECT and were independent of clinical change. Lymphocyte ß2-adrenoceptor densities were unaltered. Plasma noradrenaline concentrations were initially high, and fell with ECT in a manner paralleling clinical recovery. Plasma noradrenaline may be a more useful index of central changes during antidepressant treatment than peripheral blood cell receptor densities.
Rapid onset of perfused blood vessels after implantation of ECFCs and MPCs in collagen, PuraMatrix and fibrin provisional matrices

We developed an in vivo vascularization model in which human endothelial colony‐forming cells (ECFCs) and human mesenchymal progenitor cells (MPCs) form blood vessel networks when co‐injected (ECFC + MPC) into nude mice in rat tail type I collagen, bovine fibrin or synthetic peptide PuraMatrix matrices. We used three approaches to determine the onset of functional vascularization when ECFC + MPC suspended in these matrices were implanted in vivo. The first was immunohistochemistry to detect vessels lined by human endothelial cells and filled with red blood cells. The second was in vivo vascular staining by tail vein injection of a mixture of Ulex europaeus agglutinin I (UEA‐I), a lectin specific for human endothelium, and Griffonia simplicifolia isolectin B4 (GS‐IB4), a lectin specific for rodent endothelium. The third approach employed contrast‐enhanced ultrasound to measure the perfusion volumes of implants in individual animals over time. Human endothelial‐lined tubular structures were detected in vivo on days 1 and 2 after implantation, with perfused human vessels detected on days 3 and 4. Contrast‐enhanced ultrasound revealed significant perfusion of ECFC + MPC/collagen implants on days 1–4, at up to 14% perfused vascular volume. ECFC + MPC implanted in fibrin and PuraMatrix matrices also supported perfusion at day 1, as assessed by ultrasound (at 12% and 23% perfused vascular volume, respectively). This model demonstrates that ECFC + MPC suspended in any of the three matrices initiated a rapid onset of vascularization. We propose that ECFC + MPC delivered in vivo provide a means to achieve rapid perfusion of tissue‐engineered organs or for in situ tissue repair. Copyright © 2013 John Wiley & Sons, Ltd.
Fault diagnosis based on pruned ensemble

A new fault diagnosis method based on ensemble pruning is proposed. Ensemble pruning means to search for a good subset of ensemble members that performs as well as, or better than, the original ensemble. Margin distribution on training sets is thought as an important factor to improve the generalization performance of classifiers. In this paper, based on the margin loss minimization, a new ensemble pruning algorithm is proposed and utilized in fault diagnosis. Experiment results show the effectiveness of the proposed technique.
The value of dynamic clustering of base stations for future wireless networks

Multicell Cooperative Processing (MCP) has been identified as a key technology to underpin future 4G wireless systems. In MCP enabled systems, the Base Stations (BSs) of the network form groups that jointly process user signals in order to reduce inter-cell interference and boost performance. Although MCP can lead to significant gains, it is also accompanied by overheads that are proportional to the number of BSs that are grouped together, called the cluster size. Thus it is crucial that BS clusters are of a limited size and formed in an intelligent way for achieving high performance. In this paper we present different dynamic clustering approaches for forming BS clusters of limited size. BS clustering is no longer based on geographical criteria, e.g. proximity-based static clustering, but on the channel conditions that users experience to different BSs. Dynamic clustering algorithms capture the effect of changing channel conditions and thus exploit the inherent macrodiversity of multicell wireless systems. More specifically, we propose a dynamic clustering scheme that provides significant gains while being resilient to inaccurate information on the state of wireless channels.
Seasonal sea level variations in the Adriatic

Seasonal changes of the Adriatic Sea level, obtained by analyses of monthly sea level data measured at the Split tide gauge station in 1958-2001, are reported. The data were correlated by multivariant analysis to (1) local meteorological data on air temperature, air pressure, and precipitation, collected at the Split station and data on winds obtained from ECMWF ERA40 Reanalysis fields and (2) forcing mechanisms series (air pressure, surface heat flux, surface water flux, river runoff, winds). Surface flux data were available for only the northern Adriatic and the Po River represented all river runoff. The surface flux explains 68% of the variance in sea level while changes in local meteorological parameters explained 53%. Most of the variance was induced by changes in air pressure (32%) and heat flux (28%), while other factors did not contribute much. By determining annual (Sa) and semi-annual (Ssa) cycles, the explained variance increased to 88% for Sa tide and 95% for Ssa tide; changes were caused mostly by changes in air pressure (about 50% of the variance). Changes in the Sa heat flux cycle did not affect changes in the Sa tide but did affect Ssa tide (about 26% of the variance), presumably due to nonlinear effects driven by winds.
Mutation of conserved domain II alters the sequence specificity of DNA binding by the p53 protein.

We have mutagenized human p53 expressed in yeast and selected two mutants, 121F and 123A, which activate transcription from one, rather than the normal two, copies of the consensus p53 DNA binding sequence. Both mutants have a 6‐fold increase in affinity for a single copy of the sequence GGG CATG CCC. The 121F mutant has a decrease, and the 123A mutant an increase, in the affinity for the sequence GAA CATG TTC. This genetic and biochemical evidence supports the crystallographic finding that amino acid 120 contacts guanine in the major groove at the second position in the consensus. The major p53 binding site in the p21WAF1/CIP1 promoter resembles the GAA CATG TTC form of the consensus. Compared with wild type p53, the 121F mutant has a 7‐fold lower affinity for the p21WAF1/CIP1 site in vitro, and the 121F mutant is defective in p21 induction in vivo. Mutants with subtly altered sequence specificity may facilitate dissection of downstream pathways activated by p53.
Characterization of a Bifunctional Enzyme Fusion of Trehalose-6-Phosphate Synthetase and Trehalose-6-Phosphate Phosphatase of Escherichia coli

ABSTRACT To test the effect of the physical proximity of two enzymes catalyzing sequential reactions, a bifunctional fusion enzyme, TPSP, was constructed by fusing the Escherichia coli genes for trehalose-6-phosphate (T6P) synthetase (TPS) and trehalose-6-phosphate phosphatase (TPP). TPSP catalyzes the sequential reaction in which T6P is formed and then dephosphorylated, leading to the synthesis of trehalose. The fused chimeric gene was overexpressed in E. coli and purified to near homogeneity; its molecular weight was 88,300, as expected. The Km values of the TPSP fusion enzyme for the sequential overall reaction from UDP-glucose and glucose 6-phosphate to trehalose were smaller than those of an equimolar mixture of TPS and TPP (TPS/TPP). However, thekcat values of TPSP were similar to those of TPS/TPP, resulting in a 3.5- to 4.0-fold increase in the catalytic efficiency (kcat/Km). The Km and kcat values of TPSP and TPP for the phosphatase reaction from T6P to trehalose were quite similar. This suggests that the increased catalytic efficiency results from the proximity of TPS and TPP in the TPSP fusion enzyme. The thermal stability of the TPSP fusion enzyme was quite similar to that of the TPS/TPP mixture, suggesting that the structure of each enzyme moiety in TPSP is unperturbed by intramolecular constraint. These results clearly demonstrate that the bifunctional fusion enzyme TPSP catalyzing sequential reactions has kinetic advantages over a mixture of both enzymes (TPS and TPP). These results are also supported by the in vivo accumulation of up to 0.48 mg of trehalose per g of cells after isopropyl-β-d-thiogalactopyranoside treatment of cells harboring the construct encoding TPSP.
Intracranial Nonjugular Venous Pathways: A Possible Compensatory Drainage Mechanism

BACKGROUND AND PURPOSE: The IJVs are considered to be the main pathway draining the intracranial venous system. There is increasing evidence for the existence of alternative venous pathways. Studies using extracranial sonography techniques have demonstrated a nonjugular venous system. In the current study, we used MR images to investigate the NJV drainage system and its components (vertebral plexus, pterygopalatine plexus). The exact visualization and measurement of the intracranial NJVs could be of diagnostic importance and may have clinical importance. MATERIALS AND METHODS: A total of 64 participants with no history of neurologic disease were included in the study. All participants underwent scanning with a 2D time-of-flight, multisection sequence in the supine position. Image processing software was developed to identify and quantify the size of the IJVs and NJVs in the plane of the internal JF. For evaluation of software accuracy, all images were reviewed by a neuroradiologist experienced in neurovascular imaging preprocessing and postprocessing. RESULTS: The CSA of the NJVs correlated inversely with the CSA of the IJVs (r2 = 0.25; P < .0001). An inverse correlation was also significant when comparing IJV with NJV components (vertebral plexus: r2 = 0.19; P = .0004; pterygopalatine plexus: r2 = 0.11; P = .0069). Furthermore, only NJV cumulative CSA correlated inversely with participant age (r2 = 0.2; P = .0002). CONCLUSIONS: Our study indicates that the NJVs might serve as a compensatory drainage mechanism in the intracranial compartment. This mechanism appears less significant as the age of the patient progresses.
Building Domain Ontology: Experiences in Developing the Prophetic Ontology Form Quran and Hadith

Ontologies have been designed for the purpose of representing a domain of knowledge in a way that makes it understandable by machines and humans. Ontologies have been used in many areas in computer sciences such as knowledge engineering, semantic web, and information retrieval. Religious studies is one of the areas were ontologies are in demand. In this paper, we present the design of domain ontology about prophets and messengers in Islam from trustworthy resources: the Quran and Hadith. The ontology can be used to better understanding all life aspects of prophets and messengers in Islam. The classes, relations and properties of this special domain ontology were gathered and integrated to help researchers to identify and explore knowledge about prophets in Islam such as their lives, books and teachings, the nature of the messages they brought to their nations and tribes and much more.
Temporal Activity of Vastus Medialis Obliquus and Vastus Lateralis in Symptomatic Knee Osteoarthritis

Hinman RS, Bennell KL, Metcalf BR, Crossley KM: Temporal activity of vastus medialis obliquus and vastus lateralis in symptomatic knee osteoarthritis. Am J Phys Med Rehabil 2002;81:684–690. Objective Knee osteoarthritis has a major impact on quadriceps function, yet its effect on the specific temporal recruitment of vastus medialis obliquus and vastus lateralis is unknown. The aim of this study was to determine the electromyographic onset of vastus medialis obliquus activity relative to that of vastus lateralis in individuals with symptomatic knee osteoarthritis and in an asymptomatic control group during the functional task of stair climbing. Design Cross-sectional, comprising 41 participants with symptomatic knee osteoarthritis and 33 controls matched for age, sex, and body mass. Results No significant differences were detected in the timing of onset of vastus medialis obliquus relative to that of vastus lateralis between the osteoarthritis and control groups. Radiographic osteoarthritis severity, presence of patellofemoral joint disease, and pain intensity did not seem to influence the temporal relationship of the vastii in the osteoarthritis group. Conclusion The presence of symptomatic, radiographic knee osteoarthritis is not associated with deficits in the temporal recruitment of vastus medialis obliquus and vastus lateralis during stair climbing. This implies that selective retraining of the individual components of the quadriceps is not indicated in rehabilitation programs for patients with this disease.
Fuzzy packet size optimization for delay sensitive traffic in ad hoc networks

In this paper is considered optimal packet size definition for delay sensitive traffic in WLAN based ad hoc networks. The aim of the paper is to introduce a fuzzy set theory based online sample size definition model, which optimize packet size of delay sensitive traffic for prevailing network conditions. The selected input parameters for the model are a packet error rate (PER) and a change of PER. The model was validated by simulating delay sensitive VoIP traffic. The results prove that the WLAN based ad hoc network with AODV routing and VoIP transactions has an optimal packet size. The results also demonstrate that the developed fuzzy model is able to set sample size values to the prevailing optimum level very fast.
Decline in Basic Fibroblast Growth Factor (FGF‐2) mRNA Expression in Female Rat Hypothalamus at Puberty

There is a growing acceptance of the importance of hypothalamic growth factors in the control of sexual maturation. Basic fibroblast growth factor (bFGF, FGF‐2), a potent mitogen and neurotropic factor for brain cells in vitro, including hypothalamic cells, is widely expressed in the post‐natal CNS but its physiological functions there are largely unknown. Previously, studies of FGF‐2 mRNA regulation in vivo have been hampered by the low levels of FGF‐2 mRNA present in post‐natal tissues. We have applied a sensitive semi‐quantitative procedure based on reverse transcription followed by polymerase chain reaction amplification (RT‐PCR) to detect and estimate relative amounts of mRNAs encoding FGF‐2 and its receptor in the hypothalamic‐hypophyseal axis in individual female rats undergoing sexual maturation.
Sustainable Impact of a Primary Care Depression Intervention

Background: Re-Engineering Systems for Primary Care Treatment of Depression (RESPECT-D) sought to improve patient outcomes by disseminating the 3-component model of depression management. The purpose of this study was to determine whether an integrated model of depression management continued to be used by primary care clinicians after the end of a randomized controlled trial (RCT). Methods: A descriptive evaluation was conducted at 2 time points. First, during a 12-month period after the end of the RESPECT-D RCT when referrals to care management were determined for each of the 5 participating health care organizations. Second, 3 years after the RCT ended, when clinicians were surveyed about use of the 3-component model. Results: Three organizations continued to support the model with minimal modification. One made a major modification to it and one did not continue to support it. In the 12 months after the RCT, 1039 care management referrals were made. Seventy-one percent of RCT clinicians (n = 92) completed the follow-up survey. Of these, 87% reported using the Patient Health Questionnaire-9; 58.9% reported availability of care management and 45.1% reported availability of informal psychiatry consultation. Conclusion: Practical clinical interventions can be sustained in primary care practice after the completion of an RCT. Additional resources may be needed to sustain and spread the program.
Pancasila in the Minor Key: TVRI's Si Unyil Models the Child

The Presidential ban on television advertising in 1981 shifted the state to center screen and changed the way TVRI (Televisi Republik Indonesia) constructed its audience. After 1981, untrammeled by market considerations and with a vastly expanded national audience within its reach, TVRI interpellated its audience as a public and a national family. One segment of the family singled out as subjects for specific national address was the audience of young children. This essay presents a case study of how television asserted its role in the Indonesian government's national culture project as an important agency of political and cultural socialization through the development of the children's puppet series Si Unyil [(The Boy) Unyil], screened for the first time in April 1981. Si Unyil is perhaps the best known television program in Indonesia. The first episode was screened on April 5, 1981, and the series has been broadcast continuously ever since, making it the longest running fictional program on Indonesian television. A total of 603 episodes were screened between 1981 and 1993.
