Thermal conductivity across nanostructured porous silicon films

This paper models the effect of pore size, pore arrangement and porosity on room temperature thermal conductivity across low porosity meso-porous silicon (meso-PS) films known as n+ and p+ type PS. Whereas the meso-PS films are simulated using a three-dimensional (3D) pore network generator, the heat conduction is modeled using the Monte Carlo method (MCM) recently developed for simulating steady-state phonon transport in submicron structures. The simulations show that (i) the thermal conductivity across meso-porous films decreases when the pore size decreases or the porosity increases, in accordance with past studies. (ii) The thermal conductivity of n+ type pore network is always greater than that of p+ type due to the difference in pore morphology. Finally, the simulations corresponding to p+ type pore network are shown in good agreement with existing experimental data for low porosity p+ type PS. Such comparison confirms the validity of the current 3D modeling.
Integration of user-centred evolutionary computation with digital visualisation

This research is concerned with applying evolutionary algorithms to explore the creation and optimisation of authentic and novel human character faces. Utilising computer software to create an authentic three-dimensional character face usually requires a graphic artist to spend a considerable amount of time and attention to painstaking detail to evolve authentic facial topology. Given that character faces share many common properties of proportion and relative positioning of facial components such as eyes, nose and mouth, then perhaps some novel face may be evolved from some standard base face through a user-centred application of a stochastic search process. Further, can such a system support the non-visually creative practitioner in the realisation of his or her own conceptual visualisations of an authentic character representation? An initial investigation applying these ideas within the context of a 3D modelling environment (Maya) to creating a human face and parametrically generate faces with varying characteristics for head shape, eye, nose, and mouth is reported. This work involves the integration of an interactive evolutionary process which utilises user-selected mesh components within the Maya environment.
Comparing Forgetting Algorithms for Artificial Episodic Memory Systems

Episodic memory is essential for human cognition and has also proven necessary for some intelligent agents. The size of an episodic store grows over time unless some forgetting mechanism is in place to keep it in check. In this research, we investigate the effect that different forgetting mechanisms have on the episodic memory performance. We compare three different forgetting algorithms using three distinct episodic memory architectures in a domain that is designed to highlight the differences between then. Our results show that the choice of forgetting algorithm has a significant impact on overall agent performance. 12
Comparisons of SiC MOSFET and Si IGBT Based Motor Drive Systems

With the rapid development of silicon carbide (SiC) material quality, SiC power devices are gaining tremendous attentions in power electronics. In this paper, a SiC device based motor drive system is performed to provide a quantitative estimate of the system improvement. Two 60 kW motor drive systems based on SiC MOSFET/Schottky diode and Si IGBTs are designed. The power losses of the two inverters with sinusoidal pulse width modulation (SPWM) control are calculated analytically. By comparing the efficiencies, sizes and temperatures of the two designed systems, SiC device shows the superior advantages of smaller loss, better efficiency and smaller size in the same motor drive application.
On the Markov chain central limit theorem

The goal of this expository paper is to describe conditions which guarantee a central limit theorem for functionals of general state space Markov chains. This is done with a view towards Markov chain Monte Carlo settings and hence the focus is on the connections between drift and mixing conditions and their implications. In particular, we consider three commonly cited central limit theorems and discuss their relationship to classical results for mixing processes. Several motivating examples are given which range from toy one-dimensional settings to complicated settings encountered in Markov chain Monte Carlo.
Augmentation of Innate Host Defense by Expression of a Cathelicidin Antimicrobial Peptide

ABSTRACT Antimicrobial peptides, such as defensins or cathelicidins, are effector substances of the innate immune system and are thought to have antimicrobial properties that contribute to host defense. The evidence that vertebrate antimicrobial peptides contribute to innate immunity in vivo is based on their expression pattern and in vitro activity against microorganisms. The goal of this study was to investigate whether the overexpression of an antimicrobial peptide results in augmented protection against bacterial infection. C57BL/6 mice were given an adenovirus vector containing the cDNA for LL-37/hCAP-18, a human cathelicidin antimicrobial peptide. Mice treated with intratracheal LL-37/hCAP-18 vector had a lower bacterial load and a smaller inflammatory response than did untreated mice following pulmonary challenge with Pseudomonas aeruginosa PAO1. Systemic expression of LL-37/hCAP-18 after intravenous injection of recombinant adenovirus resulted in improved survival rates following intravenous injection of lipopolysaccharide with galactosamine or Escherichia coli CP9. In conclusion, the data demonstrate that expression of an antimicrobial peptide by gene transfer results in augmentation of the innate immune response, providing support for the hypothesis that vertebrate antimicrobial peptides protect against microorganisms in vivo.
Rheological and electrical percolation thresholds of carbon nanotube/polymer nanocomposites

Percolation thresholds of multiwalled carbon nanotube/polystyrene (MWCNT/PS) nanocomposites (NC) were determined by rheology and electrical conductivity. The percolation threshold found by electrical conductivity was 0.5% carbon nanotubes (CNT) and that by mechanical spectroscopy and relaxation measurements was 0.9% CNT. These results together with those reported in the literature show several types of percolation thresholds, depending on the average filler–filler (CNT and/or aggregates) distance in a polymer matrix. A distance close to polymer gyration radius corresponds to a “soft” rheological threshold (PC rheosoft). Close contacts between fillers giving rise to a conductive path corresponds to an electrical threshold (PC elec). At high filler concentration, fillers form a network, corresponding to a “rigid” rheological threshold (PC rheorigid). These thresholds depend on the filler content and follow the order: PC elecsoft < PC elec < PC rheorigid. POLYM. ENG. SCI., 2012. © 2012 Society of Plastics Engineers

The Effect of Rifampin on Toxoplasma gondii 1

Summary Rifampin, at concentrations of 50 μg/ml and greater, significantly inhibited multiplication of toxoplasma in L-cell cultures. Similar concentrations also inhibited growth of L-cells. No effect of rifampin was found on toxoplasma RNA synthesis in toxoplasma preparations free of mammalian cells or on RNA synthesis in L-cells. Mice which had received rifampin in high doses by the oral or intraperitoneal routes were not protected against lethal infection with toxoplasma.

Situated learning and change in organisational practices: learning the ropes of the commercialization of academic research

This paper takes a practice-based perspective on organisational learning and change and sheds light on the social processes that underlie effective changes in organisational practices. In particular, it investigates why and how practices of organisational communities of practice are transformed. I propose that management’s strategic practices can shape learning trajectories of organisational communities of practice in order to stimulate transformations in the practices that are in line with the strategic goals. Thus the paper argues that situated learning not only drives emergent changes but also enables deliberate change, planned by organisational strategists. I design a conceptual framework which synthesises insights from studies of situated change, studies of situated learning and studies of strategizing in order to address this proposition. The case studies of four Knowledge Transfer Offices in UK universities have shown that three strategic practices were commonly adopted to shape situated learning in the communities of practice and transformations of practices. Differences in transformative power of these three strategic practices are discussed.

TV Time but Not Computer Time Is Associated with Cardiometabolic Risk in Dutch Young Adults

Background TV time and total sedentary time have been positively related to biomarkers of cardiometabolic risk in adults. We aim to examine the association of TV time and computer time separately with cardiometabolic biomarkers in young adults. Additionally, the mediating role of waist circumference (WC) is studied. Methods and Findings Data of 634 Dutch young adults (18–28 years; 39% male) were used. Cardiometabolic biomarkers included indicators of overweight, blood pressure, blood levels of fasting plasma insulin, cholesterol, glucose, triglycerides and a clustered cardiometabolic risk score. Linear regression analyses were used to assess the cross-sectional association of self-reported TV and computer time with cardiometabolic biomarkers, adjusting for demographic and lifestyle factors. Mediation by WC was checked using the product-of-coefficient method. TV time was significantly associated with triglycerides (B = 0.004; CI = [0.001;0.05]) and insulin (B = 0.10; CI = [0.01;0.20]). Computer time was not significantly associated with any of the cardiometabolic biomarkers. We found no evidence for WC to mediate the association of TV time or computer time with cardiometabolic biomarkers. Conclusions We found a significantly positive association of TV time with cardiometabolic biomarkers. In addition, we found no evidence for WC as a mediator of this association. Our findings suggest a need to distinguish between TV time and computer time within future guidelines for screen time.

Criteria for Return to Sport after Anterior Cruciate Ligament reconstruction with lower reinjury risk (CR’STAL study): protocol for a prospective observational study in France

Introduction The decision regarding when to return to sport after an anterior cruciate ligament reconstruction (ACLR) is an important one. Using a variety of subjective and objective parameters, various attempts have been made to determine an optimal timeline for a return to sport after ACLR, but none have been validated. The aim of the present study is therefore to determine which criteria or combination of criteria could allow to return to sport with the lowest possible risk of reinjury. Methods and analysis This study is a prospective cohort, single-centre study, with repeated assessments at 6, 9 and 12 months post-ACL surgical reconstruction and including a 3-year follow-up of patients’ sporting activity and reinjuries. 275 patients will be included to test explanatory variables. Postural control analysis, knee laxity, questionnaires (International Knee Documentation Committee (IKDC), Tampa Scale of Kinesiophobia-11 (TSK-11), Anterior Cruciate Ligament—Return to Sport After Reinjury (ACL-RSI) and Single Assessment Numeric Evaluation (SANE)), modified Star Excursion Balance Test, running and sprinting biomechanics, Hop Tests and Isokinetic Tests will all be used. The primary outcome will be any reinjury during the follow-up period, defined as a graft rupture, a contralateral ACL rupture or any injury necessitating an interruption of training and requiring a medical consultation. Two groups will be constituted during the follow-up, separating reinjured from non-reinjured patients. In addition, classic analysis and data mining approaches will be used to build predictive models. Ethics and dissemination The results of this study will be disseminated through peer-reviewed publications and scientific presentations. Ethical approval was obtained through the ethics committee of the University Hospital of Saint-Etienne (reference number IRBN522015/CHUSTE).
Search-Based Application Security Testing: Towards a Structured Search Space

This position paper outlines a staged approach to search-based application security testing. In the first stage one searches for candidate tests in the input space that have a chance of leading to good security tests. In the second stage one selects individual candidates and uses them to select and parametrize specialized search techniques. This approach has its roots in exploratory security testing. In the first stage, the fitness of tests depends on their ability to provoke vulnerability symptoms at all, and on their relation to other tests in a test suite. In the second stage, the fittest tests are those that come closest to an exploit of a specific type of vulnerability. To evaluate the performance of such a staged approach one might use web application vulnerability scanners as a baseline.
Efficient test strategy for TDMA power amplifiers using transient current measurements: uses and benefits

A novel algorithm for fast and accurate testing of TDMA power amplifiers in a transmitter system is presented. First, the steep cost of high frequency testers can be largely complemented by the proposed method due to its ease of implementation on low-cost testers. Secondly, TDMA power amplifiers usually have a control voltage to operate the device in various modes of operation. At each of the control voltage values, all the specifications of the power amplifier are measured to ensure the performance of each tested device. A new method is proposed to test all the specifications of these devices using the transient current response of their bias circuits to a time-varying control voltage stimulus. These results in shorter test times compared to conventional test methods. The test specification values are measured to an accuracy of less than 5% for all the specifications measured. The proposed test approach can specifically benefit production test of quad-band amplifiers (GSM850, GSM900, PCS/DCS), as a single transient current measurement can be used to compute all the specifications of the device in different modes of operation, over different operating frequencies.

Volatile Compounds and Antioxidant Capacity of the Bio-Oil Obtained by Pyrolysis of Japanese Red Pine (Pinus Densiflora Siebold and Zucc.)

In the present study, sawdust bio-oil (SBO) manufactured by fast pyrolysis of Japanese red pine (Pinus densiflora Siebold and Zucc.) sawdust was analyzed for its volatile chemical compound composition and evaluated for its free radical scavenging potential, inhibition of lipid peroxidation and reducing power. Gas chromatography and mass spectroscopy revealed 29 volatile compounds, comprising 97.6% of the total volatile compounds in SBO. The antioxidant potential of SBO in terms of IC50 values was 48.44 µg/mL for hydroxyl radical scavenging, 89.52 µg/mL for 1,1-diphenyl-2-picrylhydraxyl radical scavenging, 94.23 µg/mL for 2,2'-azino-bis[3-ethylbenzothiazoline-6-sulphonic acid] radical scavenging, and 136.06 µg/mL for superoxide radical scavenging activity. The total phenol content in SBO was 5.7% gallic acid equivalent. Based on the composition of its volatile compounds, high free radical scavenging potential and antioxidant properties, SBO could be used as a source of antioxidant compounds, flavoring agents and nutraceuticals in the food, pharmaceutical, and cosmetic industries.
Developmental trajectories of gene expression reveal candidates for diapause termination: a key life-history transition in the apple maggot fly Rhagoletis pomonella

SUMMARY The timing of dormancy is a rapidly evolving life-history trait playing a crucial role in the synchronization of seasonal life cycles and adaptation to environmental change. But the physiological mechanisms regulating dormancy in animals remain poorly understood. In insects, dormancy (diapause) is a developmentally dynamic state, and the mechanisms that control diapause transitions affect seasonal timing. Here we used microarrays to examine patterns of gene expression during dormancy termination: a crucial life-history transition in the apple maggot fly Rhagoletis pomonella (Walsh). This species is a model system for host race formation and ecological speciation via changes in diapause regulation of seasonality. Our goal was to pinpoint the timing of the transition from diapause to post-diapause development and to identify candidate genes and pathways for regulation of diapause termination. Samples were taken at six metabolically defined developmental landmarks, and time-series analysis suggests that release from metabolic depression coincides with preparation for or resumption of active cell cycling and morphogenesis, defining the ‘end’ of diapause. However, marked changes in expression, including members of pathways such as Wnt and TOR signaling, also occur prior to the metabolic rate increase, electing these pathways as candidates for early regulation of diapause termination. We discuss these results with respect to generalities in insect diapause physiology and to our long-term goal of identifying mechanisms of diapause adaptation in the Rhagoletis system.
The Formation and Evolution of Intracluster Light

Using N-body simulations, we have modeled the production and evolution of diffuse, low surface brightness intracluster light (ICL) in three simulated galaxy clusters. Using an observational definition of ICL to be luminosity at a surface brightness μV > 26.5 mag arcsec-2, we have found that the fraction of cluster luminosity contained in ICL generally increases as clusters evolve, although there are large deviations from this trend over short timescales, including sustained periods of decreasing ICL luminosity. Most ICL luminosity increases come in short, discrete events that are highly correlated with group accretion events within the cluster. In evolved clusters we find that ≈10%-15% of the clusters' luminosity is at ICL surface brightness. The morphological structure of the ICL changes with time, evolving from a complex of filaments and small-scale, relatively high surface brightness features early in a cluster's history to a more diffuse and amorphous cluster-scale ICL envelope at later times. Finally, we also see a correlation between the evolution of ICL at different surface brightnesses, including a time delay between the evolution of faint and extremely faint surface brightness features that is traced to the differing dynamical timescales in the group and cluster environment.
