Relative and Absolute Reliability of a Modified Agility T-test and Its Relationship With Vertical Jump and Straight Sprint

Sassi, RH, Dardouri, W, Yahmed, MH, Gmada, N, Mahfoudhi, ME, and Gharbi, Z. Relative and absolute reliability of a modified agility t-test and its relationship with vertical jump and straight sprint. J Strength Cond Res 23(6): 1644-1651, 2009-The aims of this study were to evaluate the reliability of a modified agility T-test (MAT) and to examine its relationship to the free countermovement jump (FCMJ) and the 10-m straight sprint (10mSS). In this new version, we preserved the same nature of displacement of the T-test but we reduced the total distance to cover. A total of 86 subjects (34 women: age = 22.6 ± 1.4 years; weight = 63.7 ± 10.2 kg; height = 1.65 ± 0.05 m; body mass index = 23.3 ± 3.3 kg·m−2 and 52 men: age = 22.4 ± 1.5 years; weight = 68.7 ± 8.0 kg; height = 1.77 ± 0.06 m; body mass index = 22.0 ± 2.0 kg·m−2) performed MAT, T-test, FCMJ, and 10mSS. Our results showed no difference between test-retest MAT scores. Intraclass reliability of the MAT was greater than 0.90 across the trials (0.92 and 0.95 for women and men, respectively). The mean difference (bias) ± the 95% limits of agreement was 0.03 ± 0.37 seconds for women and 0.03 ± 0.33 seconds for men. MAT was correlated to the T-test (r = 0.79, p < 0.001 and r = 0.75, p < 0.001 for women and men, respectively). Significant correlations were found between both MAT and FCMJ, and MAT and 10mSS for women (r = −0.47, p < 0.01 and r = 0.34, p < 0.05, respectively). No significant correlations were found between MAT and all other tests for men. These results indicate that MAT is a reliable test to assess agility. The weak relationship between MAT and strength and straight speed suggests that agility requires other determinants of performance as coordination. Considering that field sports generally include sprints with change direction over short distance, MAT seems to be more specific than the T-test when assessing agility.
Muscle biopsy in the evaluation of patients with modestly elevated creatine kinase levels

The utility of muscle biopsy in patients with modest elevations of serum creatine kinase (CK) level but normal neurological examinations and nondiagnostic electrodiagnostic studies is uncertain. We performed systematic, extensive studies on muscle biopsies of 20 such patients. A definitive diagnosis was arrived at in only 1 by histochemical studies, although 4 others demonstrated minor myopathic changes. Biochemical evaluation led to a diagnosis in an additional 5. Muscle biopsy is useful for evaluating such patients, but extensive studies of the muscle are necessary. Muscle Nerve 27: 242–244, 2003
A multiobjective model for VAR planning in radial distribution networks based on tabu search

In this paper, a tabu search (TS)-based approach to provide decision support in the problem of capacitor location in radial distribution networks is presented. The model explicitly considers two conflicting and incommensurate objective functions related to cost and operational aspects of evaluation. This offers the decision maker/planning engineer the possibility to expand the range of potential alternative solutions (since he or she is not limited to an optimal solution as in single objective models), also giving him or her an active role through the expression of his or her preferences to select a satisfactory compromise solution.
The Importance of Sample Attrition in Life Cycle Labor Supply Estimation

We examine the importance of possible nonrandom attrition to an econometric model of life cycle labor supply using both a Wald test comparing attriters to nonattriters and variable addition tests based on formal models of attrition. Estimates using the Panel Study of Income Dynamics show that nonrandom attrition is of little concern when estimating prime-age male labor supply because the effect of attrition is absorbed into fixed effects in labor supply. The wage measure and instrument set have much larger effects on the estimated labor supply function of prime-age men than how one adjusts for panel attrition.
Deep learning–based real-time query processing for wireless sensor network

The data collected from wireless sensor network indicate the system status, the environment status, or the health condition of human being, and we can use the wireless sensor network data to carry out appropriate work by processing it. In recent years, using deep learning, it is possible to construct a more intelligent context-aware system by predicting future situations as well as monitoring the current state. In this article, we propose a monitoring framework for wireless sensor network streaming data analysis based on deep learning. In particular, in an environment where time requirements are strictly enforced, data analysis results must be derived within a deterministic time. Therefore, we conduct query refinement adaptively to enable timely analysis of wireless sensor network data in the predictor. Even if some sensor data that is not synchronized in time are included or even if some data have not arrived yet, reasonably accurate query analysis results can be obtained within the deadline by performing the proposed method.
Field Tests and Analysis of Torsional Interaction Between the Coal Creek Turbine-Generators and the CU HVdc System

Recent experience at the Square Butte Electric Coop project in North Dakota indicated that HVdc systems could interact adversely with turbine-generator torsional modes of vibration on adjacent units. A similar system-configuration exists with the new CU project, also in North Dakota. The CU HVdc control system was designed prior to the experience at Square Butte and hence did not include the potential for such an interaction as a design consideration. As a result, studies were initiated prior to the system startup, a torsional protective relay was ordered for the turbine-generator units, and extensive field tests were planned and carried out to measure the torsional interaction with the HVdc system. The tests and subsequent analysis showed that the system could operate without danger of a torsional instability, due in large part to a relatively high first torsional mode frequency of 19 Hz on the Coal Creek Unit. This experience has enhanced the understanding of the HVdc-torsional interaction phenomena, which will contribute to the design of future HVdc control systems to include mitigation of the potential for such adverse interaction. With this as a major design criteria, it is unlikely that such extensive testing will be essential on all future installations but the experience reported in this paper should be of benefit if similar testing is desired
Characterization of commercial and experimental sodium caseinates by multiangle laser light scattering and size-exclusion chromatography.

A range of sodium caseinate samples were characterized by a multiangle laser light scattering (MALLS) system or by the use of MALLS as an on-line detector with size-exclusion chromatography (SEC). Sodium caseinate solutions, analyzed using a MALLS system alone, gave weight-average molar mass (M(w)) values in the range 1200-4700 kDa and z-average root-mean-square radius (R(g)) values ranged from approximately 50 to 120 nm. When these solutions were ultracentrifuged at 90000g for 1 h, a cloudy top layer was formed; the subnatant was carefully removed and analyzed by SEC-MALLS. The M(w) values were found to be in the range approximately 30-575 kDa, and R(g) values ranged from approximately 22 to 49 nm. During SEC, the MALLS system detected some very large-sized material that eluted close to the void volume; this material was hardly detected by the concentration detectors, i.e., ultra-violet (UV) and differential refractive index (DRI). The intensity of the light scattering (LS) signal from this very large sized material was greatly reduced in the subnatant. SEC of sodium caseinate samples revealed two main peaks with M(w) of approximately 420-750 kDa and 39-69 kDa, respectively. The R(g) values were very large for a protein molecule, and initial calculations suggested that the shape of caseinate molecules was likely to be highly elongated.
Hypothesis based detection of building with rectilinear projection in satellite images using shade and color information

A new hypothesis based method for detecting rectilinear buildings, that have ground projection made of combination of rectangles, in satellite images is proposed. While the hypotheses are established using the lines detected in the satellite images they are verified by using shadow and color segmentation information. The proposed method is implemented in MATLAB and tested in satellite images of different urban areas. The experimental results obtained are encouraging.
Ambulatory Facility Design and Patients' Perceptions of Healthcare Quality

Objective: This research examines whether the physical attractiveness of an outpatient practice influences patients' perceptions of healthcare quality, including patient and staff perceptions of the quality of staff-patient interaction. Background: Despite the high and increasing percentage of healthcare dollars for care delivered on an outpatient basis, relatively little research has examined the relationship between the design of ambulatory facilities and patient outcomes. Few studies have examined how patients' perceptions of healthcare quality differ in the same outpatient practice before and after a move to a new facility designed to be patient-centered. This study is the second phase of a study comparing patients' perceived quality of care in ambulatory facilities that differ markedly in physical attractiveness. Methods: Using both a patient and staff survey, and structured interviews, this study compared staff and patient perceptions of healthcare quality (including staff-patient interactions) before and after a move to a new facility designed to be patient-centered. Results: Patients' perceived quality of care, and their perceptions of the quality of interaction with staff, was significantly better in the patient-centered facility. Few differences were found in actual patient-staff interaction behaviors. Conclusions: This study is consistent with other studies that examined the relationship among the physical attractiveness of healthcare settings, patient satisfaction, and perceived quality of care. For this reason, the results are more credible than they would be were they inconsistent with other research or were this the only study examining these issues. These results support the value of investing in the physical attractiveness of patient areas in the ambulatory care setting. Further research is needed to identify specific physical elements that contribute to positive attributions related to quality of care, as well as where the “tipping point” is in investments to improve physical attractiveness.
Raw and Cooked Vegetables, Fruits, Selected Micronutrients, and Breast Cancer Risk: A Case-Control Study in Germany

In 1998-2000, a case-control study of breast cancer was conducted in Heidelberg, Germany. Three hundred ten consecutively recruited cases with primary breast cancer were matched according to 10-yr age groups to 353 controls with conditions unrelated to diet or endocrine disorders. Intake of raw vegetables, total vegetables, and whole-grain products was inversely associated with breast cancer risk (highest vs. lowest quartile adjusted odds ratio [OR] 0.51, 95% confidence interval [CI] 0.31-0.84; OR = 0.62, 95% CI = 0.38-1.02; and OR = 0.57; 95% CI = 0.34-0.95, respectively). Also, high intake of some selected vitamins and minerals possessing putative DNA-stabilizing properties displayed significant inverse risk associations. Adjusted ORs were as follows: vitamin C (OR = 0.49, 95% CI = 0.2-0.88), folate equivalents (OR = 0.47, 95% CI = 0.25-0.88), â-carotene (OR = 0.46, 95% CI = 0.27-0.80), zinc (OR = 0.35, 95% CI = 0.15-0.78), and copper (OR =0.51, 95% CI = .31-1.03). In contrast, no significant association with risk was seen for an increased intake of fruits, cooked vegetables, fiber, calcium, manganese, or iron. In this population of German women, components of raw vegetables and some micronutrients appear to decrease breast cancer risk.
A High Incidence of Adjacent-1 Meiotic Segregation Pattern, Revealed by Multicolor Sperm FISH, in a Carrier Boar of a New Reciprocal Translocation t(6;16)(p13;q23)

Reciprocal translocations pose a serious problem in pig breeding due to the reduced fertility of the carriers. This paper presents a new reciprocal translocation in a phenotypically normal, but hypoprolific (20% reduction) boar. Chromosome banding as well as the FISH technique with the use of BAC and telomeric probes was applied for a detailed characterization of this chromosome rearrangement. The karyotype of the studied boar was described as 38,XY,t(6;16)(p13;q23). The meiotic segregation of the quadrivalent was studied in 1,071 sperms by multicolor FISH. The most frequent segregation patterns were alternate (47.5%) and adjacent 1 (41.9%), while adjacent 2 and 3:1 were less frequent at 1.2 and 9.2%, respectively. Surprisingly, the frequency of the adjacent-1 segregation appeared to be relatively high, when compared with human and pig reciprocal translocations studied by sperm FISH. Our study, along with a review of the literature, shows that a reduction of fertility in the carriers and the incidence of different segregation patterns of the quadrivalent may vary within a broad range, and both aspects seem to be unrelated. A need for obligatory karyotype screening programs of artificial insemination boars is emphasized.
Dietary‐Induced Overeating a

The role of the diet in promoting overeating and obesity has been the subject of considerable interest. The degree to which dietary factors stimulate overeating in humans is difficult to establish with certainty because of the many factors that influence human food intake. Research with laboratory animals, however, clearly demonstrates that certain diets induce overeating and obesity. These diets include: high-carbohydrate diets, high-fat diets, and mixed diets containing a variety of fatand sugar-rich foods, that is, the “supermarket” or “cafeteria” diet. As reviewed in several publication^,'-^ the effects of these dietary regimes on food intake, body weight, and body fat depend on a number of variables, including the strain, age, and sex of animals studied. This paper will focus on new findings concerning the orosensory and physicochemical properties of food that promote overeating in laboratory rats and the role of diet palatability in this effect. Note that the emphasis here is on overeating rather than obesity; dietary manipulations that produce obesity in the absence of overt hyperphagia will not be discussed.
Experimental haemophilic synovitis: rationale and development of a murine model of human factor VIII deficiency

Summary. Haemophilia is a genetic disease as a result of the deficiency of blood coagulation factor VIII or IX. Bleeding is common, especially into joints where an inflammatory, proliferative synovitis develops resulting in a debilitating arthritis, haemophilic arthropathy. The pathogenesis of blood‐induced haemophilic synovitis (HS) is poorly understood. The gross, microscopic and ultrastructural changes that occur in the synovial membrane following human and experimental hemarthrosis have been described. Repeated episodes of bleeding induce synoviocyte hypertrophy and hyperplasia, an intense neovascular response and inflammation of the synovial membrane. The component(s) in blood that initiates these changes is(are) not known, although iron is often proposed as one possibility. Here, we describe a novel murine model of human haemophilia A, which facilitates the examination of large number of animals and tissue specimens. The effects of hemarthrosis on the physical, gross and microscopic changes evoked following joint bleeding are described. Controlled, blunt trauma to the knee joint consistently resulted in joint swelling because of a combination of bleeding and inflammation. Hemosiderin was found in the synovial membrane. Similar to hemarthrosis in human haemophilia, joint bleeding resulted in acute morbidity evidenced by inactivity, weight loss and immobility. With time the animals recovered. The model of experimental murine HS described here has utility in the study of the pathogenesis of HS. This is the first of a series of articles, which will discuss the pathophysiology and characterize the model, with comparison of his model to others which have been published previously. It should provide a useful model to test potential therapeutic interventions.
Wheeled Mobile Manipulator Modeling for Task Space Control

Mobile manipulators have attracted a lot attention lately because they have many advantages over stationary manipulator, such as larger a work space than a stationary manipulator could have in practice. However, the proposed methods in the state of the art to obtain the kinematic model of a mobile manipulator are based in modeling separately the mobile base and the manipulator arm, and later combining both models. This paper shows a systematic approach to obtain the kinematic model of mobile manipulators that transforms in the modeling problem of a stationary manipulator with non-holonomic kinematic constraints in the joints; it is also showed an example of the application of the method, where the kinematic and dynamic models are obtained with extensions of the same tools used in stationary robots.
The asymptotic distribution of symbols on diagonals of random weighted staircase tableaux

Staircase tableaux are combinatorial objects that were first introduced due to a connection with the asymmetric simple exclusion process (ASEP) and Askey‐Wilson polynomials. Since their introduction, staircase tableaux have been the object of study in many recent papers. Relevant to this paper, Hitczenko and Janson proved that distribution of parameters on the first diagonal is asymptotically normal. In addition, they conjectured that other diagonals would be asymptotically Poisson. Since then, only the second and the third diagonal were proven to follow the conjecture. This paper builds upon those results to prove the conjecture for the kth diagonal where k is fixed. In particular, we prove that the distribution of the number of α's (β's) on the kth diagonal, k > 1, is asymptotically Poisson with parameter 1/2. In addition, we prove that symbols on the kth diagonal are asymptotically independent and thus, collectively follow the Poisson distribution with parameter 1. © 2016 Wiley Periodicals, Inc.

A 0.8V, 7/spl mu/A, rail-to-rail input/output, constant G/sub m/ operational amplifier in standard digital 0.18/spl mu/m CMOS

A two-stage amplifier, operational at 0.8V and drawing 7/spl mu/A, has been integrated in a standard digital 0.18/spl mu/m CMOS process. Rail-to-rail operations at the input are enabled by complementary transistor pairs with g/sub m/ control. The efficient rail-to-rail output stage is biased in class AB. The measured DC gain of the amplifier is 75dB, and the unity-gain frequency is 870kHz with a 12pF, 100k/spl Omega/load. Both input and output stage transistors are biased in weak inversion.
Simultaneous enhancement of current and breakdown voltage in AlGaN / GaN MOSHEMTs using sputtered / PECVD gate-dielectrics

A new SiO2-deposition scheme combining radio frequency (rf) magnetron sputtering and plasma enhanced chemical vapor deposition (PECVD) has been developed to produce gate-SiO2 for GaN-based metal-oxide-semiconductor high-electron-mobility-transistors (MOSHEMTs). The high-density sputtered-SiO2 was employed to suppress the gate leakage current while the low-density PECVD-SiO2 was used to protect the sputtering damage, and also to increase the drain current via stress-induced-polarizations. Thus-obtained MOSHEMT exhibited a drain current of over 100 mA and a gate leakage current of 4.2 nA/mm. A high breakdown voltage of 634 V was achieved for a short gate-drain length of 6 μm, showing the promise of the new SiO2-deposition scheme for the fabrication of GaN-based MOSHEMTs for high-power applications.
ValLigURL: a server for ligand-structure comparison and validation.

A new web-based tool called ValLigURL is described. It can be used by practising crystallographers to validate the geometry of a ligand and to compare the conformation of a ligand with all instances of that ligand in the structural database (wwPDB). In addition, it can be used by structural bioinformaticians to survey the quality or conformational diversity of any ligand across the entire structural database. The server is freely accessible at the URL http://eds.bmc. uu.se/eds/valligurl.php.
Thermal conduction normal to thin silicon nitride films on diamond and GaN

Self-heating effects severely limit the performance of high-power gallium nitride (GaN) high-electron-mobility transistors (HEMTs). High thermal resistances within micrometers of the transistor junction often dominate the junction temperature rise and fundamentally restrict the device power handling capability. The use of high-thermal-conductivity diamond near the junction can address this thermal limitation, but this approach requires careful attention to the quality of the thermal interface between the GaN and diamond. Here we use time-domain thermoreflectance (TDTR) to measure thermal resistances of thin silicon nitride (SiN) films with varying thicknesses on both diamond and GaN. Measurement of these two sets of samples provides an estimate for the thermal resistance between the GaN and diamond since the SiN film can be used as a bonding layer between the two materials. The effective resistances of the SiN film and bottom interface (SiN/diamond or SiN/GaN) range from 22 to 37 m2 K GW-1 for both sets of samples. Our findings suggest the possibility of achieving 22 m2 K GW-1 as the GaN/diamond thermal interface resistance.
Real-Time Digital Simulator Enabled Hardware-inthe-Loop Electric Machine Drive Lab

This paper presents real-time digital simulator enabled hardware-in-the-loop (HIL) electrical machine drive lab setup for educational purposes. The objective of this work is to create a platform for laboratory experiments to enhance drive control design and testing. In the proposed setup, an OPAL-RT real-time digital simulator (RT-LAB) is used to implement the desired control schemes for AC and DC electric machine drives. Control blocks are created in Matlab/Simulink while measurement signals from the motors are taken into Matlab/Smimulink through RT-LAB I/O interface. RT-LAB software compiles the MATLAB code to C code and downloads it to OP-4500 OPAL-RT simulator through network connections. PWM signals are then generated by OP-4500 I/O board and sent to an power electronic board to drive a DC or AC machine.
Design of hardware circuit based on a neural network model for rapid detection of center of gravity position

This paper proposes a rapid detection method for the center of gravity based on a neural network model. It is suitable for the rapid response requirement such as attitude control of a gait robot or real time torque control of a running car. The proposed method detects the center of gravity position on a straight line by using only the hardware circuit composing of common electronic devices instead of software, microprocessor and AD converter. The circuit employs some neural based comparators without the learning function to simplify the circuit structure. The detection circuit using some parallel processing neural comparators rapidly detects the center of gravity position on a straight line. In this paper, the circuit is designed and fabricated with electronic devices, and the circuit experiment shows the performance of the position detection.
