Coopération chercheurs-praticiens pour analyser l’activité et concevoir des ressources de formation
Authors: Leblanc Serge 
Published: September 2017

Cet article propose de questionner le type de coopération engagée entre les chercheurs et les praticiens lorsqu’il s’agit d’étudier l’activité humaine et ses transformations. Pour présenter notre manière de concevoir et mettre en œuvre des recherches qui constituent une alternative aux « recherches académiques » et/ou aux « recherches-actions », nous développerons : a) l’intérêt d’un programme de recherche technologique en relation organique avec un ou plusieurs programmes de recherche empirique, b) une vision de la coopération chercheurs-praticiens pensée comme une voie de développement et de compréhension de l’activité humaine, c) l’articulation entre l’analyse de l’activité et le processus de conception. Nous proposerons des illustrations concrètes sur ces trois axes à partir d’études qui s’inscrivent dans le programme de recherche empirique et technologique du cours d’action et qui ont été menées dans les domaines de la formation des meneurs d’attelage et des enseignants.
Schwartz Functions on Real Algebraic Varieties
Authors: Elazar Boaz , Shaviv Ary 
Published: September 2017

AbstractWe define Schwartz functions, tempered functions, and tempered distributions on (possibly singular) real algebraic varieties. We prove that all classical properties of these spaces, defined previously on affine spaces and on Nash manifolds, also hold in the case of affine real algebraic varieties, and give partial results for the non-affine case.
Intraoperative Echocardiographic Detection of Septal Aneurysm and Additional Ventricular Septal Defect in a Child with Tetralogy of Fallot
Authors: Das Sambhunath 
Published: September 2017

ABSTRACT
A 2-year-old child was diagnosed with subaortic ventricular septal defect (VSD) with severe infundibular and valvular pulmonary stenosis (PS) by transthoracic echocardiography. Intraoperative transesophageal echocardiography (TEE) detected aneurysmal interventricular and interatrial septum (IAS), subaortic VSD, and right ventricular outflow tract (RVOT) with an additional midmuscular VSD. The aneurysmal interventricular septum (IVS) was repaired. An accessory tricuspid papillary muscle was attached to RVOT, which was augmented with a transannular pericardial patch to have minimal postoperative gradient without sacrificing the accessory papillary muscle (APM). This rare case poses a challenge to the anesthetist and surgeon in the form of diagnostic differences, severe right ventricle (RV) dysfunction with aneurysmal IVS, and difficulty in reconstruction of RVOT. Intraoperative TEE played a greater role to diagnose the IVS aneurysm, additional VSD and guide for appropriate surgery.

Published: September 2017

ABSTRACT
Atrial myxoma is the most frequent intracardiac tumor, accounting for nearly 50% of benign cardiac tumours in adults. We present here a rare case report of a solitary left atrial myxoma attached to the left atrial wall near the origin of the right pulmonary vein. The stalk of tumor was not attached to the interatrial septum, which is the most common site of attachment. Instead, it was attached on the wall of left atrium adjacent to the interatrial septum. Surgical exploration confirmed its attachment in the left atrium near the origin of right upper pulmonary vein.

Dental Informatics: A Click to the Future
Authors: Sushanth V Hirekalmath , Imranulla Mohamed 
Published: September 2017

ABSTRACT
Biomedical informatics is one of the upgrading maturing disciplines. One of its subdisciplines, dental informatics, is beginning to emerge as its own entity. While there are numerous trained dental informaticians, dental faculty, and administrators, in general, they are not very familiar with dental informatics as an area of scientific inquiry. Scientific investigations in informatics center primarily around model formulation, system development, system implementation, and the study of effects. Informatics draws few of its scientific methods mainly from information science, computer science, cognitive science, and telecommunications. Dental informatics provides many types of research questions and methods from its parent discipline, biomedical informatics. However, there are indications that certain research questions in dental informatics require concrete solutions that have not yet been developed in other informatics fields. This article provides an overview of the unique features of biomedical and information sciences.

A Transport Protocol for Future Wireless Internets
Authors: Chandra Deddy , Harris Richard J 
Published: September 2017

The traditional assumptions made by TCP
about the operation of wired networks are often found to be invalid for wireless networks. Standard TCP semantics such as end-to-end flow control, congestion control mechanisms and error recovery provide reliability in wired networks. However, wireless communication systems have different characteristics when compared to wired networks that include higher bit error rates, higher latency, limited bandwidth, multipath fading of the signals and handoff. In this paper, we propose an enhancement to TCP that we shall call ETCP, which improves upon conventional TCP when it is applied to the wireless environment. Our simulation results show significant improvements to TCP performance with respect to packet loss detection.
A Hybrid Random Early Detection Algorithm for Improving End-to-End Congestion Control in TCP/IP Networks
Authors: Haider Aun , Harris Richard 
Published: September 2017

The successful operation of the present Internet depends mainly upon TCP/IP which employs end-to-end congestion
control mechanisms built in the end hosts. In order to further enhance this paradigm of end-to-end control the
Random Early Detection algorithm (RED) has been proposed, which starts to mark or drop packets at the onset of congestion.
The paper addresses issues related to the choice of queue length
indication parameters for packet marking/dropping decisions
in RED-type algorithms under varying traffic conditions. Two
modifications to RED are proposed: (i) use of both instantaneous queue size and its Exponential Weighted Moving Average
(EWMA) for packet marking/dropping and (ii) reducing the effect of the EWMA queue size value when the queue size is less than
$min_{th}$ for a certain number of consecutive packet arrivals.

The newly developed Hybrid RED algorithm can effectively improve the performance of TCP/IP based networks while working in a control loop formed by either dropping or marking of packets during congestion epochs. New guidelines are developed for better marking/dropping of packets to achieve a faster response of RED-type algorithms. The hybrid RED algorithm has been tested using ns-2 simulations, which show better utilization of network bandwidth and a lower packet loss rate.
On the Performance Analysis of Wireless Receiver in Cascaded Fading Channel
Authors: Malhotra Jyoteesh , Sharma Ajay K. , Kaler R. S. 
Published: September 2017

In this paper, we provide a unified analysis for wireless system over cascaded fading channels modeled either by cascaded Nakagami-m or Weibull fading models. These cascade fading models are developed by the product of independent Nakagami-m or Weibull random variables, which are not necessary identically distributed. The performance measures such as amount of fading, average bit error rate, and signal outage are computed in this analysis. We first use the Padé approximation (PA) technique to find simple to evaluate rational expressions for the moment generating function (MGF) of output signal-to-noise ratio (SNR), unlike previously derived intricate expressions in terms of MeijerG function for cascaded Nakagami-m fading channel. Rational expressions for the MGF of the cascaded Weibull random variable are also computed to provide new set of performance results. Using these rational expressions, we analyze the performance of wireless receivers under a range of representative channel fading conditions using
both cascaded fading models. To verify the correctness of the proposed rational expression formulation numerical and computer simulations has been done, which shows perfect match.
Postural Analysis of a Developing Country’s Municipal Solid Waste Handlers and a Reference Group of Hospital General Hands using the RULA Method
Authors: Ncube France , Jacobeth Ncube Esper , Voyi Kuku 
Published: September 2017

BACKGROUND: Municipal solid waste handlers perform various work activities which may contribute to the onset of work-related musculoskeletal disorders (WRMDs). This study conducted a postural analysis of these workers and a reference group of hospital general hands in order to identify unsafe working postures requiring correction. METHODS: The Rapid Upper Limb Assessment (RULA) methodology was used for postural analysis to 30 municipal solid waste handlers (MSWHs) and a reference group of 30 hospital general hands (HGHs) involved in similar work activities. Field observations and photography were used to collect data. Collected data was analysed using STATA version 13.RESULTS: The Mann-Whitney test was used to compare the two groups. Results showed significant differences (p < 0.05) for lifting, carrying and emptying activities. For both groups, the mean postural scores for pushing, pulling and standing activities were mainly in the low risk category and not statistically significant (p > 0.05).CONCLUSION: Results of the present study show unsafe RULA postural scores to MSWHs with regard to lifting, carrying and emptying of refuse bins. Such scores are suggestive of an elevated risk to developing WRMDs in these workers compared to the reference group.
Tectonic and Climatic Controls on Asymmetric Half‐Graben Sedimentation: Inferences From 3‐D Numerical Modeling

Published: September 2017

AbstractThe tectono‐sedimentary evolution of asymmetric extensional systems driven by the activity of major normal faults or detachments associated with footwall exhumation is often characterized by a sequence of slower, faster, and ultimately again slower subsidence rates in the center of hanging wall half‐grabens during their synkinematic and postkinematic evolution. We have studied this specific evolution by the means of 3‐D stratigraphic numerical modeling that accounts for the variability of the sediment and water flux combined with climatic and sea level variations, and sediment compaction. The model setup is constrained by observations from the Pannonian back‐arc basin of central Europe. Our modeling predicts the formation of low‐order tectonic and higher‐order sea level and climate‐driven transgressive‐regressive sedimentary cycles. Furthermore, we model and analyze the autocyclic nature of the depositional systems. Retrograding‐prograding cycles are visible on the proximal flank of the half‐grabens by their different spatial and temporal expressions, while depocenters record large water depth variations linked to the specific and episodic activity of normal faults and their migration with time. The application to a system of multiple half‐grabens in the Pannonian Basin, which are activated in different locations, at different times and with different kinematics, demonstrates a complex interplay between direct sediment sourcing and the sediments' ability to bypass trapping subbasins and paleo‐reliefs created by eroded footwalls.

AbstractThe development of wearable breath or sweat sensor arrays for human performance monitoring is increasingly important for providing personalized health information under various environmental conditions. A major challenge is the lack of sensing elements responsive uniquely to moisture‐dominated breathing and sweating processes, which is critical for differentiating other chemical or biological species from the moisture‐dominated environment. Here a novel class of nanofibrous paper chemiresistors decorated with dendronized nanoparticles that exhibit structurally tunable and negative‐going responses to human breathing and sweating is reported. The nanocomposite device features flexible membrane‐type scaffold derived from multilayered nanofibrous paper as a biocompatible matrix and dendronized gold nanoparticles with tunable sizes and shapes to enable structural diversity and molecular sensitivity. Key elements of novelty include the immobilization of poly(ether‐ester) dendrons with oligoethylene glycol spacers on gold nanoparticles and the combination of hydrogen bonding and van der Waals interactions between partially interpenetrating dendrons, leading to tunable and unique response characteristics to breathing and sweating processes. The results demonstrate the first example of nanofibrous paper chemiresistors decorated with dendronized nanoparticles as a promising new strategy toward constructing sensing interfaces for wearable breath and sweat sensors.

AbstractObjectivesTo investigate the relationships of biological, behavioral, familial, and environmental characteristics with siblings´ physical activity (PA) levels as well as the intrapair resemblance in PA.MethodsThe sample comprises 834 (390 females) biological siblings [brother‐brother (BB), sister‐sister (SS), brother‐sister (BS)] aged 9 to 20 years. Total PA index (TPAI) was estimated by questionnaire. Information on potential behavioral, familial, and environmental correlates was obtained by self‐report; body mass index (BMI), biological maturation, and physical fitness were measured. Multilevel models were used to analyze siblings´ clustered data, and sibling resemblance was estimated with the intraclass correlation (ρ).ResultsOn average, younger sibs, those more physically fit, and those with more parental support had greater TPAI. Further, BB pairs had higher TPAI levels than SS or BS pairs, but also had greater within‐pair variance. When adjusted for all covariates, SS pairs demonstrated greater resemblance in TPAI (ρ = 0.53, 95%CI = 0.38–0.68) than BS (ρ = 0.26, 95%CI = 0.14–0.43) or BB pairs (ρ = 0.18, 95%CI = 0.06–0.44).ConclusionsAge, physical fitness, and parental support were the best predictors of TPAI levels. A moderate level of resemblance in TPAI was observed in SS pairs, while lower resemblance was found for BS and BB pairs. These findings may be due to differences in the roles of shared genetic factors, familial, and environmental characteristics across different sibling types.
Stereospecific Reactions of Donor–Acceptor Cyclopropanes with Thioketones: Access to Highly Substituted Tetrahydrothiophenes
Authors: Augustin André U. , Sensse Maximilian , Jones Peter G. , Werz Daniel B. 
Published: September 2017

AbstractLewis‐acid‐catalyzed reactions of 2‐substituted cyclopropane 1,1‐dicarboxylates with thioketones are described. Highly substituted tetrahydrothiophenes with two adjacent quaternary carbon atoms were obtained in a stereospecific manner under mild conditions and in high yield when using AlCl3 as Lewis acid. Moreover, an intramolecular approach was successfully implemented to gain access to sulfur‐bridged [n.2.1] bicyclic ring systems. Conversion of selenoketones, the heavier analogues, under similar conditions resulted in the formation of various tetrahydroselenophenes.
New Results on Stabilization of Fractional‐Order Nonlinear Systems via an LMI Approach
Authors: Thuan Mai Viet , Huong Dinh Cong 
Published: September 2017

AbstractThis paper considers the systematic design of robust stabilizing state feedback controllers for fractional‐order nonlinear systems. By using the Lyapunov direct method and a recent result on the Caputo fractional derivative of a quadratic function, stabilizability conditions expressed in terms of linear matrix inequalities are derived. The controllers can then be derived by using existing computationally effective convex algorithms. Two numerical examples with simulation results are provided to demonstrate the effectiveness of our results.
Multiple organic cation transporters contribute to the renal transport of sulpiride
Authors: Li Liping , Weng Yayun , Wang Wei , Bai Mengru , Lei Hongmei , Zhou Hui , Jiang Huidi 
Published: September 2017

AbstractSulpiride, a selective dopamine D2 receptor blocker, is used widely for the treatment of schizophrenia, depression and gastric/duodenal ulcers. Because the great majority of sulpiride is positively charged at physiological pH 7.4, and ~70% of the dose recovered in urine is in the unchanged form after human intravenous administration of sulpiride, it is believed that transporters play an important role in the renal excretion of sulpiride. The aim of the present study was to explore which transporters contribute to the renal disposition of sulpiride. The results demonstrated that sulpiride was a substrate of human carnitine/organic cation transporter 1 (hOCTN1) and 2 (hOCTN2), human organic cation transporter 2 (hOCT2), human multidrug and toxin efflux extrusion protein 1 (hMATE1) and 2‐K (hMATE2‐K). Sulpiride accumulation from the basolateral (BL) to the apical (AP) side in MDCK‐hOCT2/pcDNA3.1 cell monolayers was much greater than that in MDCK‐hOCT2/hMATE1 cells, and cimetidine dramatically reduced the intracellular accumulation of sulpiride from BL to AP. In addition, the accumulation of sulpiride in mouse primary renal tubular cells (mPRTCs) was markedly reduced by inhibitors of Oct2 and Octns. The results implied that OCTN1, OCTN2, OCT2, MATE1 and MATE2‐K probably contributed to the renal transfer of sulpiride, in which OCT2 mediated the uptake of sulpiride from the bloodstream to the proximal tubular cells, while MATEs contributed to the sulpiride efflux from the proximal tubular cells to the renal lumen, and OCTNs participated in both renal secretion and reabsorption.
How should we evaluate research on counselling and the treatment of depression? A case study on how the National Institute for Health and Care Excellence's draft 2018 guideline for depression considered what counts as best evidence
Authors: Barkham Michael , Moller Naomi P. , Pybis Joanne 
Published: September 2017

AbstractBackgroundHealth guidelines are developed to improve patient care by ensuring the most recent and ‘best available evidence’ is used to guide treatment recommendations. The National Institute for Health and Care Excellence's (NICE's ) guideline development methodology acknowledges that evidence needed to answer one question (treatment efficacy) may be different from evidence needed to answer another (cost‐effectiveness, treatment acceptability to patients). This review uses counselling in the treatment of depression as a case study, and interrogates the constructs of ‘best’ evidence and ‘best’ guideline methodologies.MethodThe review comprises six sections: (i) implications of diverse definitions of counselling in research; (ii) research findings from meta‐analyses and randomised controlled trials (RCTs); (iii) limitations to trials‐based evidence; (iv) findings from large routine outcome datasets; (v) the inclusion of qualitative research that emphasises service‐user voices; and (vi) conclusions and recommendations.ResultsResearch from meta‐analyses and RCTs contained in the draft 2018 NICE Guideline is limited but positive in relation to the effectiveness of counselling in the treatment for depression. The weight of evidence suggests little, if any, advantage to cognitive behaviour therapy (CBT) over counselling once risk of bias and researcher allegiance are taken into account. A growing body of evidence from large NHS data sets also evidences that, for depression, counselling is as effective as CBT and cost‐effective when delivered in NHS settings.ConclusionSpecifications in NICE's updated guideline procedures allow for data other than RCTs and meta‐analyses to be included. Accordingly, there is a need to include large standardised collected data sets from routine practice as well as the voice of patients via high‐quality qualitative research.
The Nature of Hydrated Protons on Platinum Surfaces
Authors: Kim Youngsoon , Noh Chanwoo , Jung YounJoon , Kang Heon 
Published: September 2017

AbstractThe nature of hydrated protons formed at water/metal interfaces is one of the most intriguing research questions in the field of interfacial chemistry. We prepared coadsorption layers of hydrogen and water on a Pt(111) surface in ultrahigh vacuum and studied the ionization of adsorbed hydrogen atoms to H+ ions by employing a combined experimental and theoretical approach. Spectroscopic evidence obtained by mass spectrometry and reflection absorption infrared spectroscopy as well as corresponding density functional theory calculations consistently show that adsorbed hydrogen atoms ionize into multiply hydrated proton species (H5O2+, H7O3+, and H9O4+) on the surface, rather than H3O+. Then, upon addition of a water overlayer, the metal‐bound hydrated protons spontaneously evolve into three‐dimensional fully hydrated proton structures through proton transfer along the water overlayer. The stability of hydrated protons on the Pt surface and their bulk dissolution behavior suggest the possibility that surface hydrated protons are a key intermediate in electrochemical interconversion between adsorbed H atoms and H+(aq) in water electrolysis and hydrogen evolution reactions.
