Quantized thermal transport across mechanical contacts of rough surfaces ( Supplementary information )

The heater temperature was calibrated using the measurement of the electrical resistance of the heater using the circuitry shown in Fig. S2 a. During the experiments a constant bias, Vtot is applied. The electrical resistance is measured from the voltage drop across the heater. The resulting current–voltage diagram is shown in Fig. S2 b. The electrical resistance changes as a function of the power dissipated in the heater due to the temperature dependence of the electrical resistivity of the silicon. To determine the electrical resistance Rel of the heater as a function of temperature, we exploit the fact that the maximum electrical resistance occurs at a temperature determined by the doping level in the heater. For the cantilevers used here this occurs at 550 ◦C, see Fig. S2 c. For other temperatures, we assume that the dissipated electrical power is proportional to the temperature rise in the heater. The temperature calculation using this method has been shown to have an uncertainty of less than 30% and is thereby comparable to the uncertainty of other methods used to measure temperatures in microscale structures. The calibration process and the underlying assumptions were described in detail by Menges et al. [2].
Effect of hydration state on strength, power, and resistance exercise performance.

PURPOSE Although many studies have attempted to examine the effect of hypohydration on strength, power, and high-intensity endurance, few have successfully isolated changes in total body water from other variables that alter performance (e.g., increased core temperature), and none have documented the influence of hypohydration on an isotonic, multiset, multirepetition exercise bout typical of resistance exercise training. Further, no investigations document the effect of hypohydration on the ability of the central nervous system to stimulate the musculature, despite numerous scientists suggesting this possibility. The purposes of this study were to examine the isolated effect of hydration state on 1) strength, power, and the performance of acute resistance exercise, and 2) central activation ratio (CAR). METHODS Seven healthy resistance-trained males (age = 23 +/- 4 yr, body mass = 87.8 +/- 6.8 kg, body fat = 11.5 +/- 5.2%) completed three resistance exercise bouts in different hydration states: euhydrated (EU), hypohydrated by approximately 2.5% body mass (HY25), and hypohydrated by approximately 5.0% body mass (HY50). Investigators manipulated hydration status via exercise-heat stress and controlled fluid intake 1 d preceding testing. RESULTS Body mass decreased 2.4 +/- 0.4 and 4.8 +/- 0.4% during HY25 and HY50, respectively. No significant differences existed among trials in vertical jump height, peak lower-body power (assessed via jump squat), or peak lower-body force (assessed via isometric back squat). CAR tended to decrease as hypohydration increased (EU = 95.6 +/- 4.9%, HY25 = 94.0 +/- 3.1%, HY50 = 92.5 +/- 5.1%; P = 0.075, eta(p)(2) = 0.41). When evaluated as a function of the percentage of total work completed during a six-set back squat protocol, hypohydration significantly decreased resistance exercise performance during sets 2-3 and 2-5 for HY25 and HY50, respectively. CONCLUSION These data indicate that hypohydration attenuates resistance exercise performance; the role of central drive as the causative mechanism driving these responses merits further research.
Robust BER estimator for DBPSK modulation

Fast industrial test of RF circuits is today a main challenge issue with current wireless standards. As the impact of the test on the overall product cost is no longer negligible, there is a strong motivation in simplifying the test. With the emergence of low throughput systems like ultra-narrow band ones, this topic becomes even more critical. The industrial test must be performed in few seconds per chip, it allows only few data bits for testing, making the real BER estimation unfeasible. In this paper we present a new way of estimating the BER for DBPSK modulation, which ensure accuracy, fast convergence and robustness against impairments like CFO. We also compare it to several classic BER estimators for the same kind of system, and discuss about the performances.
Impact of abciximab on mortality and reinfarction in patients with acute ST‐segment elevation myocardial infarction treated with primary stenting

Objectives: To combine data from all randomized trials of abciximab versus placebo or open‐label control in patients with STEMI treated with primary stenting to assess the short‐term and long‐term mortality, reinfarction, and bleeding complications. Background: Clinical trials of adjunctive abciximab therapy in patients with ST‐segment elevation myocardial infarction (STEMI) undergoing primary stenting have produced conflicting results. Methods: Formal searches of electronic databases (Medline, Cochrane) from January 1990 to April 2009 were performed. Five trials randomizing 2,937 patients (1,475 in the abciximab group, 1,462 in the placebo group) were included in the analysis. Results: When compared with placebo, abciximab was not associated with a significant reduction in the odds of 30‐day (OR 0.71, 95% CI: 0.45–1.14, P = 0.16) or long‐term (OR 0.85, 95% CI: 0.48–1.50, P = 0.57) mortality. Similarly, the rate of reinfarction was not statistically different at 30 days (OR 0.59, 95% CI: 0.30–1.17, P = 0.13) or at long‐term follow‐up (OR 0.67; 95% CI: 0.39–1.16, P = 0.16). However, when trials with upstream use of thienopyridines were excluded, abciximab was associated with a significant reduction in the composite of death or reinfarction at 30 days (OR 0.45; 95% CI: 0.26–0.77, P = 0.004) but not at long‐term follow‐up (OR 0.59; 95% CI: 0.27–1.28, P = 0.18). Conclusion: Routine use of abciximab in patients with STEMI treated with primary stenting may reduce short‐term rates of death or reinfarction in patients not administered preprocedural thienopyridine therapy, but does not appear to be beneficial in those who receive preprocedural thienopyridines. © 2009 Wiley‐Liss, Inc.
Smoothing reference centile curves: the LMS method and penalized likelihood.

Refence centile curves show the distribution of a measurement as it changes according to some covariate, often age. The LMS method summarizes the changing distribution by three curves representing the median, coefficient of variation and skewness, the latter expressed as a Box-Cox power. Using penalized likelihood the three curves can be fitted as cubic splines by non-linear regression, and the extent of smoothing required can be expressed in terms of smoothing parameters or equivalent degrees of freedom. The method is illustrated with data on triceps skinfold in Gambian girls and women, and body weight in U.S.A. girls.
Translational control by eIF2α in neurons: Beyond the stress response

The translation of mRNAs is a tightly controlled process that responds to multiple signaling pathways. In neurons, this control is also exerted locally due to the differential necessity of proteins in axons and dendrites. The phosphorylation of the alpha subunit of the translation initiation factor 2 (eIF2α) is one of the mechanisms of translational control. The phosphorylation of eIF2α has classically been viewed as a stress response, halting translation initiation. However, in the nervous system this type of regulation has been related to other mechanisms besides stress response, such as behavior, memory consolidation and nervous system development. Additionally, neurodegenerative diseases have a major stress component, thus eIF2α phosphorylation plays a preeminent role and its modulation is currently viewed as a new opportunity for therapeutic interventions. This review consolidates current information regarding eIF2α phosphorylation in neurons and its impact in neurodegenerative diseases. © 2016 Wiley Periodicals, Inc.
Science as a Map in Technological Search 911

A large body of work argues that scientific research increases the rate of technological advance, and with it economic growth. The precise mechanism through which science accelerates the rate of invention, however, remains an open question. Conceptualizing invention as a combinatorial search process, this paper argues that science alters inventors’ search processes, by leading them more directly to useful combinations, eliminating fruitless paths of research, and motivating them to continue even in the face of negative feedback. These mechanisms prove most useful when inventors attempt to combine highly coupled components; therefore, the value of scientific research to invention varies systematically across applications. Empirical analyses of patent data support this thesis. Copyright  2004 John Wiley & Sons, Ltd.
Quantitative flow measurements for classification of ovarian tumors by transvaginal color Doppler sonography in postmenopausal patients

Color Doppler and Duplex measurements were obtained in 83 (42 benign, 41 malignant) ovarian tumors in postmenopausal patients. An ATL UM9/HDI was used. The following flow criteria were analyzed: lowest resistance index (RI) and pulsatility index (PI), total number of arteries and number of central arteries and the maximum, mean and sum of systolic, end‐diastolic and time‐averaged maximum velocities of all intratumoral vessels. In 98% of malignant and in 85% of benign lesions, vessels were detected. All flow criteria showed highly significant differences between benign and malignant tumors (p < 0.0001). However, there was a considerable overlap between benign and malignant tumors (e.g. the median of the lowest RI was 0.62 (range 0.26–1.0) for benign and 0.40 (0.22–0.66) for malignant tumors; the median of the maximum systolic velocity was 17.5 cm/s (range 5.2–61.5 cm/s) for benign and 47.05 cm/s (14.6–105.0 cm/s) for malignant tumors).
Impact of Organizational Culture on the Indian I.T Workforce's Job Satisfaction and Stress: Qualitative Report from SMEs operating in Trivandruam

The qualitative paper investigates the impact of organisational culture on the job satisfaction of employees working in the small and medium size I.T firms operating in the south of India. The paper undertakes the application of Denison’s model for exploring the organisational culture and Spector JSS survey to examine employees' job satisfaction through 5 points Likert Scale. This exploratory study targeted 400 employees in the 30 different organisations however 280 participated in this study. For data analysis mainly MS Excel Integrated package was used for the purpose of labelling, coding, and percentages. The results indicates that organisational culture has a significant positive impact on the employees' job satisfaction. It drives them in determining organisational goals as well strengthen strategic direction to the organisation. Additionally, learning culture enhance employees' commitment and career growth chances. However, it is evident that females have higher job satisfaction in contrast to males. Despite, there is high level of satisfaction evident but it is also found that reward and promotion increase job satisfaction among lower level staff while organisational culture has direct relationship with stress.
Secure inter-organizational workflow through the combination of access control models

Nowadays, various systems or organizations can collaborate and exchange information or services to work together and conduct exchanges in order to achieve a common goal. Workflow technology which tends to automate business processes and provide support for their management is now an active research sector. Cooperation between heterogeneous workflows entails security challenges, both organizational and technical. The emergence of the concept of Virtual Organization (VO), which consists of a temporary alliance of organizations, around a network structure where the pooling of material software and human resources, makes it possible to achieve this common objective. This cannot be achieved without safety problems. To ensure a certain level of security, it is essential to check whether the behavior of the systems of the different participants respects their security policies. We propose, through this paper, a secure approach of workflow cooperation of our multi-layer model [1] based on the combination of two access control models, namely ABAC and ORBAC in the framework of the VO.
Continuous-wave yellow-green laser at 0.56  μm based on frequency doubling of a diode-end-pumped ceramic Nd:YAG laser.

We present what is, to the best of our knowledge, the first report on yellow-green laser generation based on the frequency doubling of the 1.1 μm transitions in Nd:YAG ceramics. By employing an 885 nm diode laser as the end-pumping source and a lithium triborate crystal as the frequency doubler, the highest continuous wave output powers of 1.4, 0.5, and 1.1 W at 556, 558, and 561 nm are achieved, respectively. These result in optical-to-optical efficiencies of 6.9%, 2.5%, and 5.4% with respect to the absorbed pump power, respectively.
Impact of enzymes and toxins potentiality of four Aspergillus species to cause aspergillosis

Aspergillus species are the main causing agents of invasive apergillosis chest disease. Eighty isolates of Aspergillus species, A. flavus (20), A. fumigatus (15), A. niger (30) and A. terreus (15 isolates), previously isolated and identified from aspergillosis suspected patients at our lab in Assiut university hospitals, were assayed for their enzymes and toxins profile. The results revealed that, all of the tested isolates were able to utilize calf lung tissue and produce catalase and peroxidase enzymes. Meanwhile, 82.5-90% of the fungal isolates had the ability to produce protease, lipase, urease and phospholipase, whereas, 70% of isolates exhibited hemolytic activities. Thin layer chromatography (TLC) of the cleaned extracts of the tested isolates exhibited the ability of all A. flavus isolates assayed to produce aflatoxins B1 and G1, 53%, moreover, A. fumigatus isolates produced fumagillin and gliotoxin. On the other side, 43.3% and 23.3% of A. niger isolates produced ochratoxins and gliotoxin respectively. Virulence assay of 10 μl of gliotoxin standard and cleaned extracts of A. fumigatus toxic isolates showed necrotic area on Guinea Pigs lungs compared to the control. Thus, opportunistic fungi isolated from aspergillosis patients possess high enzymatic and toxic profile that might play an important role in their mycopathy.
Effects of a dielectric substrate on the radiation characteristics of a spiral antenna with slots

The arms of a spiral antenna are printed on the bottom surface of a dielectric substrate and are placed in contact with an absorbing strip installed in a shallow cavity. The antenna characteristics when a slot is cut into each of the arms are investigated with the permittivity of the dielectric substrate as a parameter. The investigation shows that, as the permittivity is increased, the center frequency of a stopband, f-stop, in the frequency response becomes lower. Subsequently, the change in f-stop is investigated with the thickness of the substrate as a parameter. It is found that the effect of the thickness on f-stop is not remarkable. It is also revealed that the inherent radiation pattern and gain of the spiral antenna are maintained outside the stopband.
Platoon Control of Connected Vehicles from a Networked Control Perspective: Literature Review, Component Modeling, and Controller Synthesis

The platooning of connected and automated vehicles has the potential to significantly benefit the road traffic, including enhancing highway safety, improving traffic capacity, and reducing fuel consumption. This paper presents a four-component analysis framework for platoon systems from a networked control perspective, including a literature review by network awareness, unified models of key components, and two application cases for controller synthesis. The networked control perspective naturally decomposes a platoon into four interrelated components, namely, 1) node dynamics (ND), 2) information flow topology (IFT), 3) formation geometry (FG), and 4) distributed controller (DC). The existing literature is categorized under this framework and analyzed according to the component features. The unified mathematical models are derived for platoons with linear dynamics and distributed controllers. As a case study, a distributed controller synthesis method is introduced for homogeneous platoons, which guarantees the internal stability in the presence of a broad class of topologies with/without uniform time-delays. The effectiveness is demonstrated by numerical simulations.
Children’s response to food branding at three laboratory test-meals

Food marketing has been shown to influence children’s food requests, preferences, and intake. The purpose of the following studies was to test children’s responses to a form of food marketing, known as branding, at three laboratory test-meals that varied in packaging. The aims were to (1) identify familiar and well-liked food brands in a community sample of 7-10 year-old children, (2) determine the effects of food branding on 7-10 year-old children’s meal liking and (3) energy intake, and (4) identify child-level characteristics (e.g., weight status, external responses to food) that may explain variance in children’s responses to food branding in the laboratory. The primary outcomes, children’s meal liking and energy intake, were measured in three meal conditions that varied by packaging: (1) Branded: packaging with familiar food brands, e.g., Kraft, (2) Unbranded: plain white packaging, and (3) “Kaiyo”: packaging with a novel brand and cartoon character developed by our lab. In the pilot Brand Familiarity study, the food brands selected for the Branded condition of the main fMRI Branding study were familiar and well-liked by a community sample of children. In the fMRI Branding Study, contrary to previous findings, there were no significant effects of brand condition on children’s meal liking or energy intake using mixed models analyses. Other factors, such as children’s BMI z-score, frequency of usual consumption, and fullness may be stronger predictors of food liking and energy intake in the laboratory than food branding.
Innovation for Survival: Entrepreneurial Response of Indian MSMEs to Demonetization

The aim of this paper is to explore entrepreneurial response of micro, small and medium enterprises (MSMEs) in India with respect to demonetization. MSMEs act as crucial originator of entrepreneurship and innovation because they provide employment to large number of people and also contribute to growth of an economy. In the ever changing business environment, SMEs have to respond frequently in an innovative way. These frequent changes in the business environment forces enterprises to think out of box and reinvent themselves. In the recent times, there have been changes in use of technology and demonetization in India. This has attracted progressive response from the small and medium enterprises. But it has also resulted in failure of many enterprises. This study presents entrepreneurial response to changes in technology and demonetization. Some MSMEs have adopted innovative techniques to tackle challenges of demonization. The result shows that increase in registrations of MSMEs. They have adopted process innovations to tackle demonetization. There is more use of technology to cut overall cost. The use of technology is more in the payment methods, designing and other operational activities etc.
Endoscopic Iliotibial Band Release in Snapping Hip

Several open surgical techniques have been used to treat recalcitrant cases of snapping iliotibial band with varying results. Recently, endoscopic techniques have become available. The purpose of this study was to investigate the results of a modified endoscopic iliotibial band release using a longitudinal retrospective case series. Fifteen patients (three men and 12 women) with symptomatic external snapping hip were treated with an endoscopic release of the iliotibial band. The average age was 25 years (range 16-37 years). The procedure was performed in the lateral decubitus position using two portals; the iliotibial band was transversally released using a radiofrequency hook probe. The mean follow-up period was 33.8 months (range 12-84 months). The snapping phenomenon was overcome in all the patients. The mean pre-op pain VAS score was 5.5 mm (range 5-7 mm) and the mean post-op pain VAS score was 0.53 mm (range 0-2 mm) with a statistically significant reduction with respect to the pre-operative value (p<0.0001); sixty percent of the patients were pain-free. The mean postoperative Harris Hip Score was 97.5 (range 94-100). No revision procedures were indicated and all the patients returned to their previous level of activity. The mean patient satisfaction score was, on average, 9.3 mm (range 8-10 mm) on the VAS scale. No complications occurred. Endoscopic iliotibial band release is a safe and reproducible technique with excellent results in terms of snapping phenomenon resolution, patient satisfaction, and return to previous level of activity. After strenuous sporting activities 40% of patients complained of very slight pain.
Biogenic inputs to ocean mixing

Summary Recent studies have evoked heated debate about whether biologically generated (or biogenic) fluid disturbances affect mixing in the ocean. Estimates of biogenic inputs have shown that their contribution to ocean mixing is of the same order as winds and tides. Although these estimates are intriguing, further study using theoretical, numerical and experimental techniques is required to obtain conclusive evidence of biogenic mixing in the ocean. Biogenic ocean mixing is a complex problem that requires detailed understanding of: (1) marine organism behavior and characteristics (i.e. swimming dynamics, abundance and migratory behavior), (2) mechanisms utilized by swimming animals that have the ability to mix stratified fluids (i.e. turbulence and fluid drift) and (3) knowledge of the physical environment to isolate contributions of marine organisms from other sources of mixing. In addition to summarizing prior work addressing the points above, observations on the effect of animal swimming mode and body morphology on biogenic fluid transport will also be presented. It is argued that to inform the debate on whether biogenic mixing can contribute to ocean mixing, our studies should focus on diel vertical migrators that traverse stratified waters of the upper pycnocline. Based on our understanding of mixing mechanisms, body morphologies, swimming modes and body orientation, combined with our knowledge of vertically migrating populations of animals, it is likely that copepods, krill and some species of gelatinous zooplankton and fish have the potential to be strong sources of biogenic mixing.
A Model for Sustaining Evidence-Based Practices in a Statewide System

Over the past 20 years, efforts have been made to broadly disseminate evidence-based practices (EBPs). However, the public health impact of EBPs has yet to be realized and most EBPs are not sustained. Few structured models exist for disseminating and sustaining EBPs across large systems. This article describes the EBP Dissemination and Support Center (DSC) model and how it was used to sustain trauma-focused cognitive behavioral therapy (TF-CBT) across Connecticut. More than 600 clinicians at 35 agencies have been trained and nearly all agencies have sustained TF-CBT for up to 9 years. More than 6,200 children have received TF-CBT and have shown improvements in outcomes and quality indicators. Recommendations are made for using or adapting the DSC model.
