[Physical exercise and sport activities in patients with and without coronary heart disease].

BACKGROUND The quantity and intensity of physical activity required for the primary prevention of coronary heart disease remain unclear. Therefore, we examined the association between physical activity and coronary risk. METHODS We studied 100 patients with chest pain, 78 men and 22 women, not older than 65 years, admitted to a coronary care unit. Patients were subdivided in 3 groups: the first group included patients with acute myocardial infarction, the second group included patients with chronic heart disease, the third included patients with non-ischemic chest-pain. A questionnaire on daily physical activity was filled by each patient. RESULTS A significantly higher percentage of patients with myocardial infarction and coronary heart disease had a sedentary life style compared to patients of the third group. Compared with subjects without heart disease, a significantly higher percentage of patients of the first and second group covered a daily average distance shorter than 500 meters, while a significantly inferior percentage covered a distance longer than 1 Km every day. A significantly lower percentage of patients with coronary heart disease practised sport compared with the third group. At the time of hospitalization a very small percentage of coronary heart disease patients still practised sport. CONCLUSIONS The association between physical activity and reduced coronary risk is clear; in order to obtain benefits it is sufficient just walking every day. Regarding physical activity, continuity is important: patients, who practised sport only in juvenile age, breaking off when older, may lose the obtained advantages.
ACT-CV: Die Erweiterung von ACT-R um Bildverarbeitungsalgorithmen erlaubt die schnelle Erzeugung mächtiger Benutzermodelle

Ein immer wichtiger werdendes Werkzeug fur die prospektive Gestaltung von Artefakten ist die kognitive Modellierung. Dabei werden kognitive Architekturen eingesetzt, deren Aufbau psychologischen Erkenntnissen uber die Fahigkeiten und Beschrankungen menschlichen Handelns entspricht, und die damit die Erzeugung valider Benutzermodelle erleichtern. Fur den praktischen Einsatz der kognitiven Modellierung bei der Gestaltung muss auch der Entwicklungsaufwand fur die Modelle bedacht werden. In dieser Arbeit wird mit ACT-CV ein Werkzeug dargestellt, das die direkte Interaktion der kognitiven Architektur ACT-R mit zu gestaltenden Softwareoberflachen auf einfache Art ermoglicht. Der Einsatz von ACT-R und ACT-CV wird beispielhaft anhand einer Untersuchung zur Wahrnehmung von Autobahnschildern im Fahrsimulator dargestellt.

Feasibility Assessment of a Wind Power Plant with Insufficient Local Wind Data Using Cascade-Correlating Neural Network

Original scientific papir The introduction of incentive schemes for wind power plants throughout most European countries has sparked a substantial growth in interest from investors. In rushing to qualify for their part of the approved quotas, investors may not properly evaluate their investments, causing some of them to be economically unjustifiable. When assessing wind power plant feasibility, a key factor is the historic wind data. It is used as the basis for selecting the type, number and layout of the wind turbines. Unfortunately, historic wind data for a potential wind power plant location is often scarce, meaning investors do not have the data needed for making valid decisions on the quality of potential wind power plant projects. This paper describes a method for wind power plant output power estimation even if no historic wind data is available for the given location. A cascade correlation neural network is applied on wind characteristic measurements from remote locations. The results are verified by comparison of the predicted output power, obtained by using the proposed method, and already operational wind power plant with the actual values. A significant correlation exists between these two, confirming that the proposed method can be used as a robust tool for assessing the feasibility of potential wind power plant locations.
Interference avoidance based on multi-step-ahead prediction for cognitive radio

Opportunistic spectrum access (OSA) which allows a secondary user to access channels when primary users are not transmitting has been considered a promising way to increase the spectrum efficiency. To coexist with the primary user in the same frequency band, the secondary user has to adopt strict interference control rules to avoid interference towards primary users. This paper proposes using interference time ratio (ITR) (i.e. the fraction of a primary user¿s burst that is interfered by secondary transmission) as a measure of how much the primary user is impacted by secondary user for OSA system. A scheme based on multi-step-ahead prediction is proposed to predict the ITR and control the ITR so that it does not exceed a predefined threshold. To further illustrate the proposed interference avoidance scheme, two cases with different primary user traffic model are studied and simulated. The simulation and analysis results show that within acceptable predicting step number, primary user¿s burst could be well protected and precise ITR control could be achieved through the proposed interference avoidance scheme.
Point of care in your pocket: a research agenda for the field of m-health.

A frontier mindset fosters real and rapid innovation in mobile health. This fast, iterative approach should not be lost, especially given the speed with which mobile and wireless technologies evolve, but caution is warranted. Although well on track towards attaining its goal of reaching 1 million mothers by 2012, Text4Baby, a free mobile text service sponsored by Johnson & Johnson in the United States of America, is a case in point.
Tetrakis{2-[2-(2,6-dichloroanilino)phenyl]ethanoato-κ2 O:O′}bis[(dimethyl sulfoxide-κO)copper(II)](Cu—Cu): a binuclear CuII complex with the non-steroidal anti-inflammatory drug diclofenac

The title compound, [Cu2(C14H10Cl2NO2)4(C2H6OS)2], comprises a CuII 2 core that is quadruply bridged by four carboxylate ligands with the dimethyl sulfoxide ligands binding along the Cu⋯Cu axis. The four carboxylate ligands bind in a bidentate syn–syn bridging mode. Molecules reside on crystallographic inversion centres bisecting the mid-point of the Cu⋯Cu axis. There are no intermolecular interactions of note.
Total modular wrist prosthesis: a new design

The common modes of failure of total wrist arthroplasty have been fracturing, loosening, pain on pronation and supination, and muscle soft‐tissue imbalance. To overcome some of these problems a total modular wrist prosthesis has been designed for use both as a primary prosthesis and for revision surgery. An uncemented and cemented radial component, secure fixation in three metacarpal bones, and an unconstrained and constrained version account for the modularity, including optional treatment of the distal radioulnar joint. We present the design of the prosthesis including the preliminary clinical and radiographic results after a mean follow‐up of 20 months in 32 patients of whom four have had earlier implants revised.
Sunxiuqinia faeciviva sp. nov., a facultatively anaerobic organoheterotroph of the Bacteroidetes isolated from deep subseafloor sediment.

A facultatively anaerobic organoheterotroph, designated JAM-BA0302(T), was isolated from a deep subseafloor sediment at a depth of 247.1 m below the seafloor off the Shimokita Peninsula of Japan in the north-western Pacific Ocean (Site C9001 , water depth 1180 m). Cells of strain JAM-BA0302(T) showed gliding motility and were thin, long rods with peritrichous fimbriae-like structures. Growth occurred at 4-37 °C (optimum 30 °C; doubling time 8 h), at pH 5.4-8.3 (optimum pH 7.5) and with 5-60 g NaCl l(-1) (optimum 20-25 g l(-1)). The isolate utilized proteinaceous substrates such as yeast extract, tryptone, casein and Casamino acids with O2 respiration or fermentation. Strain JAM-BA0302(T) was a piezotolerant bacterium that could grow at pressures as high as 25 MPa under aerobic conditions and 10 MPa under anaerobic conditions. The G+C content of the genomic DNA was 43.2 mol%. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain JAM-BA0302(T) was most closely related to yet-undescribed strains recently isolated from various marine sedimentary environments (>99.6 % 16S rRNA gene sequence similarity) and was moderately related to Sunxiuqinia elliptica DQHS-4(T), isolated from a sea cucumber farm sediment (95.5 % 16S rRNA gene sequence similarity) within the Bacteroidetes. The phylogenetic analysis suggested that the isolate should belong to the genus Sunxiuqinia. However, low DNA-DNA relatedness (<11 %) and many physiological and molecular properties differentiated the isolate from those previously describedhttp://dx.doi. org/10.1601/nm.22746. We propose here a novel species of the genus Sunxiuqinia, with the name Sunxiuqinia faeciviva sp. nov. The type strain is JAM-BA0302(T) ( = JCM 15547(T) = NCIMB 14481(T)).
Vibration-mediated uv photodesorption: Ammonia on GaAs.

A surprisingly large isotope effect is observed in nonthermal uv photodesorption of ammonia from GaAs(100). The cross section for ${\mathrm{NH}}_{3}$ photodesorption is 4 times larger than for ${\mathrm{ND}}_{3}$, a fact which cannot be explained using existing photodesorption models, e.g., the conventional Menzel-Gomer-Redhead model. We take this as the first evidence for uv-driven photodesorption from electronically quenched, vibrationally excited ground-state adsorbates.
Plasma exchange and prednisone in Guillain‐Barré syndrome

A controlled randomized trial of plasma exchange combined with prednisone was compared with supportive care alone in patients with Guillain-Barré syndrome (GBS). There was no significant improvement in the treated group over the controls. The sample size, albeit small (12 treated and 13 controls), had the power (95% chance) to detect a change of 2 British Medical Research Council grades of strength between the groups. The difference in our results and others that indicated a beneficial effect of plasma exchange may reflect an adverse effect of prednisone on recovery in GBS. Failure to find a benefit of plasma exchange in our patients also raises the possibility that GBS may be a heterogeneous disorder with humoral factors playing a role in some but not all patients.
CD44v10 expression in the mouse and functional activity in delayed type hypersensitivity

We have described recently that expression of CD44 exon v10 (CD44v10) is down‐regulated upon metastasis of squamous cell carcinoma, whereas it is up‐regulated in skin metastases of malignant melanoma. The striking regulation of CD44v10 prompted us to generate a murine CD44v10‐specific monoclonal antibody to define expression and possible functions of this particular CD44 variant isoform. In the mouse, expression of exon v10 was restricted to basal layers of the epidermis and squamous epithelium of the oral cavity, the esophagus, the omasum, glandular epithelium of the submandibular and the uterine gland, as well as subpopulations of bone marrow cells and activated lymphocytes. Expression started late during development, e.g., was not observed before day 16 of gestation and there was no evidence for developmental regulation of CD44v10 expression. Functional in vivo studies revealed that anti‐CD44v10 had no effect on wound healing but inhibited edema and granuloma formation in delayed type hypersensitivity (DTH). Furthermore, lymphocyte‐monocyte interactions could be inhibited by anti‐CD44v10. Because a CD44v10 transfected tumour line did not show any distinct pattern of cell‐matrix or cell‐cell adhesion, the data point toward an involvement of CD44v10 in cell migration, possibly by acting as a target structure for cytokines/chemokines provided by the contacted partner cell.

Therapy for youths with anxiety disorders: a second randomized clinical trial.

Ninety-four children (aged 9-13 years) with anxiety disorders were randomly assigned to cognitive behavioral treatment or waiting-list control. Outcomes were evaluated using diagnostic status, child self-reports, parent and teacher reports, cognitive assessment and behavioral observation: maintenance was examined using 1-year follow-up data. Analyses of dependent measures indicated significant improvements over time, with the majority indicating greater gains for those receiving treatment. Treatment gains returned cases to within nondeviant limits (i.e., normative comparisons) and were maintained at 1-year follow-up. Client age and comorbid status did not moderate outcomes. A preliminary examination of treatment segments suggested that the enactive exposure (when it follows cognitive-educational training) was an active force in beneficial change. Discussion includes suggestions for future research.
Designing and Building an Automatic Information Retrieval System for Handling the Arabic Data

This paper aimed to design and build an Automatic Information Retrieval System to handle the Arabic data. Also, this paper presents some type of comparison between the retrieval results using the vector space model in two different indexing methods: the full-ward indexing and the root indexing. The proposed Automatic Information Retrieval system was implemented and built using a traditional model technique: Vector Space Model (VSM) where the cosine measure similarity was used. The output results indicate and show that the root indexing improved the retrieval performance more than the full-ward indexing on the Arabic documents; furthermore it reduces the size of stored data and minimizes the time of system processing.
A New Channel-Base Current Function for Lightning Studies

In this paper, we propose a new channel-base current function for lightning studies. Main features of the new function are presented, also by comparison with existing expressions; relevant advantages are highlighted. For this new function, closed-form solutions of the time integral (representing the transferred charge), of the Fourier transform, and of the specific energy are given.
A Complete Isothermal Model for the Lateral Insulated Gate Bipolar Transistor on SOI technology

While there are several analytical models dedicated to the vertical IGBT there is virtually no reliable model for the Lateral IGBT (LIGBT). LIGBTs are increasingly popular in smart power and power integrated circuits, especially in those applications where high voltage and high current capabilities are required. Silicon on insulator (SOI) could be the future technology for power devices and integrated circuits due to its much improved device isolation. In this work we report for the first time a complete analytical model for the SOI LIGBT based on semiconductor physics with very few fitting parameters. The model is assessed against finite element device simulations and experimental results.
Performance of Multi Pulse Position Amplitude Modulation for TH IR-UWB Communication Systems

The multi pulse position amplitude modulation scheme for time-hopping multiple access impulse radio ultrawideband communication systems has been presented in this paper. Multi pulse position amplitude modulation is a hybrid modulation technique, which combines multi pulse position modulation and pulse amplitude modulation. It is shown that multi pulse position amplitude modulation significantly outperforms pulse position modulation with respect to bandwidth efficiency. The multi pulse position amplitude modulation error probability over IEEE 802.15. 3a multipath fading channels in multiuser environment is derived. The system analysis shows that the proper selection of modulation parameters can improve the system performance at the cost of hardware complexity (and vice versa).
The Importance of Survey Research Standards

Every discipline within fields of research has instituted guidelines and templates for research endeavors and subsequent publications of findings, with the ultimate result being an increase in quality and acceptance by researchers within and across disciplines. These significant efforts are by nature ongoing, as well they should. These enhancements and guideline developments have been instituted in basic science disciplines, clinical pharmacy, and pharmacy administration relevant and related to subsequent scholarly publication of research findings. Specific research endeavors have included bench research, clinical trials and randomized clinical trials, meta analyses, outcomes research, and large scale database analyses. A similar need for quality and standardization also exists for survey research and scholarship. The purpose of this paper is to clarify why this is important and crucial for the Journal and our academy.
A 15-base-pair element activates the SPS4 gene midway through sporulation in Saccharomyces cerevisiae

Sporulation of the yeast Saccharomyces cerevisiae represents a simple developmental process in which the events of meiosis and spore wall formation are accompanied by the sequential activation of temporally distinct classes of genes. In this study, we have examined expression of the SPS4 gene, which belongs to a group of genes that is activated midway through sporulation. We mapped the upstream boundary of the regulatory region of SPS4 by monitoring the effect of sequential deletions of 5'-flanking sequence on expression of plasmid-borne versions of SPS4 introduced into a MATa/MAT alpha delta sps4/delta sps4 strain. This analysis indicated that the 5' boundary of the regulatory region was within 50 bp of the putative TATA box of the gene. By testing various oligonucleotides that spanned this boundary and the downstream sequence for their ability to activate expression of a heterologous promoter, we found that a 15-bp sequence sufficed to act as a sporulation-specific upstream activation sequence. This 15-bp fragment, designated UASSPS4, activated expression of a CYC1-lacZ reporter gene midway through sporulation and was equally active in both orientations. Extending the UAS fragment to include the adjacent 14-bp enhanced its activity 10-fold. We show that expression of SPS4 is regulated in a manner distinct from that of early meiotic genes: mutation of UME6 did not lead to vegetative expression of SPS4, and sporulation-specific expression was delayed by mutation of IME2. In vivo and in vitro assays suggested that a factor present in vegetative cells bind to the UASSPS4 element. We speculate that during sporulation this factor is modified to serve as an activator of the SPS4 gene or, alternatively, that it recruits an activator to the promoter.
Emulation of a Permanent-Magnet Synchronous Generator in Real-Time Using Power Hardware-in-the-Loop

Permanent-magnet synchronous generators (PMSGs) are used in several applications of traction electrification such as power supplies for auxiliary systems and vehicle on-board range-extenders. In this paper, a PMSG is emulated using power hardware in-the-loop. This emulation scheme provides a method to eliminate risks and costs associated with the testing, prototyping, and validation of controllers for power converters and other parts of the traction system. The proposed scheme can be used for testing of motor drives’ different parameters, thereby enabling the testing of a variety of electrical machine drives where the machine prototype is unavailable. The voltage output of the proposed emulator system replicates the voltage generated within the real-time model. The terminal voltage from the real-time model depends on the load connected to the emulator terminals; the current drawn from the emulator output terminals is sensed and fed back to enable the emulator to replicate the PMSG characteristics in steady state and transients. The performance of the system for nonlinear loads, such as a rectifier with a capacitor filter and transient conditions, is also experimentally verified and presented along with validation against a physical PMSG coupled to a dynamometer.
Multi-instrumental studying of interaction between heavy metal ions and free aminoacids

The main contribution of this work is in use of different techniques for the study of interactions in the field of metallomics. Interactions of free amino acids with heavy metals are subjects, which have only partial scientific interest. However, both the transport of metals and metal binding with free amino acids and/or small molecules have been still only poorly understood. We developed few methods spectrophotometric, flow injection analysis and chromatographic both with various type of electrochemical detection, which all were successfully used for studying of creation of complexes between cadmium or platinum derivatives in vitro.
Design, Synthesis, and Biological Evaluation of a Novel Water‐soluble Prodrug of Docetaxel with Amino Acid as a Linker

The synthesis and preliminary evaluation of derivatives of docetaxel with novel amino acid as a linker named as LK‐193˜LK‐196 was described. The C2′‐modified compound LK‐196 behaves as a prodrug; that is, docetaxel is generated upon exposure to human plasma. The compound was also found to have greatly improved water solubility. The pharmacodynamic results showed LK‐196 had the self‐evident inhibitory effect on tumor growth in vivo, which is a promising candidate for further biological evaluation.
Assessment of nano-scale asynchronous PCFB circuits under extreme process variation

Quasi-Delay-Insensitive (QDI) asynchronous circuit are known as a category of asynchronous circuits that are intrinsically robust toward timing variation. QDI circuit can be sound engineered using template-based design methodology and only under isochronic fork timing assumptions. Hence, generation and verification of these timing constraints are necessary steps in practical designs of QDI circuits in nano-scale era under large process variability. This paper presents an evaluation of how timing variation impacts the functionality of template-based QDI asynchronous circuits. We model a generic structure of a QDI template called PCFB using the signal transition graph specification and using a lemma to detect the isochronic forks candidate. Extensive quantitative analysis is exploited to justify the isochronic forks among the obtained candidate forks. Experimental results show that QDI asynchronous templates have extreme robustness property in the variable environments.
