Predictors and Outcomes of Secondary Prevention Medication in Patients with Coronary Artery Disease Undergoing Percutaneous Coronary Intervention

Background: Evidence on factors associated with guideline-directed secondary prevention medication (GDPM) after percutaneous coronary intervention (PCI) and its effect on the prognosis of patients with coronary artery disease (CAD) is lacking in China. Aims: To ascertain predictors of GDPM in real-world clinical practice and to assess the effect of GDPM on clinical outcomes. Design: A retrospective cohort study. Methods: Consecutive patients admitted to Fuwai Hospital between January 2013 and December 2013 were recruited. GDPM comprised aspirin, clopidogrel, statins, β-blockers, and angiotensin-converting enzyme inhibitors/angiotensin Ⅱ receptor blockers. The primary outcome was five-year major adverse cardiovascular event (MACE) (cardiac death, myocardial infarction [MI] and unplanned revascularization). Multivariable logistic regression was used to identify predictors of prescribing GDPM. Multivariable Cox regression was used to examine the relationship between GDPM and clinical outcomes. Results: 10,067 patients were followed up for a median of 5.0 years (interquartile range: 4.3–5.2), 45.1% were prescribed with GDPM. Presenting with ST-segment elevation MI (adjusted OR = 3.252 [2.832–3.736]), prior MI (adjusted OR = 2.174 [1.948–2.425]), more stents implanted (adjusted OR = 1.063 [1.022–1.106]), overweight (adjusted OR = 1.136 [1.038–1.243]), obesity (adjusted OR = 1.274 [1.100–1.476]), diabetes (adjusted OR = 1.225 [1.115–1.344]), and hypertension (adjusted OR = 3.556 [3.196–3.956]) predicted the prescription of GDPM. Advanced age (adjusted OR = 0.556 [0.379–0.816]) was associated with lower prescription rate of GDPM. Patients with GDPM had lower rate of 5-year MACE (adjusted HR = 0.889 [0.808–0.978]) relative to those without GDPM. Conclusions: Despite the benefit of GDPM in improving the prognosis of CAD patients undergoing PCI, gaps still exist in GDPM prescription in real-world clinical practice. Our study determined target populations for physicians to strive to promote the application of GDPM.
Simple Configurations for Second Order Bandpass Filters with Improved Selectivity on One Side

Simple configurations for two order bandpass filters with improved selectivity on one side are presented in this paper. This kind of filters use the modified open loop resonators with tapping line feedings. Through properly adjusting the coupling schemes, improved selectivity on lower or higher side could be obtained. It could be foundapplicable inmany cases especially that higher selectivity is needed onone side of the filter together with the low insertion loss. Index Terms –Bandpass filter, transmission zero, electric coupling, magnetic coupling
Effects of unipedal standing training on mechanical and neuromuscular systems

The proprioception training is frequently used in the prevention of articular lesions and in the rehabilitation of sports injuries. This training restores the neuromuscular functions and is essential to recover the articulation stability (Fitzgerald et al. 2000; Taube et al. 2007). The therapist frequently uses the Freeman’s board, but other instruments of rehabilitation exist. This study on unipedal standing training, using a soft foam carpet, aims to assess the effects on the neuromuscular adaptations and the articular stability.
Dual‐square‐ring‐shaped slot antenna for wideband circularly polarized radiation

A compact dual‐square‐ring‐shaped slot antenna using a microstrip feed line is proposed for wideband circularly polarized (CP) radiation. The antenna consists of a combined dual‐square‐ring‐shaped slot along the diagonal direction and a microstrip feed‐line along with stub in the orthogonal direction. The slot and feeding structures are fabricated on the opposite planes of a low cost FR4 substrate. The stub width and a dual‐square‐ring‐shaped slot are optimized for wideband CP radiation with good impedance matching. The measured 3‐dB axial ratio and 10‐dB return loss bandwidths of the proposed antenna are 47% (2.1–3.4 GHz) and 75% (1.92–4.25 GHz), respectively. The measured gain is more than 2.0 dBic over the 3‐dB axial ratio bandwidth. © 2014 Wiley Periodicals, Inc. Microwave Opt Technol Lett 56:2645–2649, 2014
Elektrotechnische und elektrophysikalische Untersuchungen der lontophorese und Galvanisation

Obwohl über die lontophorese schon Hunderte von klinischen und experimentellen Arbeiten geschrieben worden sind, wissen wir bis jetzt nicht, wieviel Gramm oder Milligramm von den Medikamenten durch Strom in den,. Organismus eingeführt werden, wohin das eingeführte Arzneimittel gelangt, welche Konzentration es im Organismus erreicht und wodurch sich die Wirkungen eines Medikamentes unterscheiden, je nachdem, ob dieses durch lontophorese in den Organismus eingeführt, äußerlich angewandt oder injiziert wurde. Ohne Klärung dieser Fragen kann auch die Frage der Dosierung nicht entschieden werden, was sich als das größte Hindernis für eine richtige Anwendung der lontophorese erweist.
Development of a high‐speed electromagnetic repulsion mechanism for high‐voltage vacuum circuit breakers

This paper presents a design and testing of a new high‐speed electromagnetic driving mechanism for a high‐voltage vacuum circuit breaker (VCB). This mechanism is based on a high‐speed electromagnetic repulsion and a permanent magnet spring (PMS). This PMS is introduced instead of the conventional disk spring due to its low spring energy and more suitable force characteristics for VCB application. The PMS has been optimally designed by the 3D nonlinear finite‐elements magnetic field analysis and investigated its internal friction and eddy‐current effect. Furthermore, we calculated the dynamic of this mechanism coupling with the electromagnetic field and circuit analysis, in order to satisfy the operating characteristics—contact velocity, response time, and so on, required for the high‐speed VCB. A prototype VCB, which was built based on the above analysis, shows sufficient operating performance. Finally, the short circuit interruption tests were carried out with this prototype breaker, and we have been able to verify its satisfying performance. © 2008 Wiley Periodicals, Inc.

Decoupled dual-dipole rectennas on a conducting surface at 2.4 GHz for wireless battery charging

A linearly polarised decoupled dual-dipole rectenna (DDDR) with a novel microstrip-decoupling structure is presented for wireless battery charging applications at the 2.4-GHz industrial, scientific and medical (ISM) band. It consists of decoupled dual dipole (DDD) antenna and a Villard's voltage doubler (VVD) rectifier, and is able to operate close to a conducting surface. The DDD provides 5.6% bandwidth centralised at ~2.42 GHz and about 4 dBi gain from each element. The half power beam width (HPBW) of this design in the XZ-plane is about 120° from each antenna. High isolation is achieved with only 3-mm edge-to-edge separation. The DDD is 37% smaller than two standard patch antennas located on the same substrate without a decoupling structure. The DDDR is able to fully charge a standard 4.8-V NiMH battery to 5.1 V in 5 h over a distance of 23 cm.
Contested social relations in the platform economy: Class structurisation and collectivisation in ride-hailing services in India

The development of platform capitalism is restructuring social relations across the globe by altering traditional hierarchical structures, internal labour relations and their micro-political interactions. Digitally mediated platforms appear to be changing relational dynamics, contributing to a growth in individualisation among the workers. The platform economy, in general, and ride-hailing services, in particular, represent an emerging capitalistic regime that is breeding a working class with often contradictory class locations and class positions. Because the class dimension in the existing literature concerning platform workers in India has been less critically approached, this research intends to use class-based theorisation to analyse capital–labour relations in the ride-hailing service, with the aim of reflecting on the linkages between class location, class consciousness and class practices among the workers. This article highlights how the internal contradictions, combined with the external structural factors, lead to growing instrumental collectivism among the platform working class that falls short of challenging the capitalistic platform regime.
Intelligent mobility research for robotic locomotion in complex terrain

The objective of the Autonomous Intelligent Systems Section of Defence R&D Canada - Suffield is best described by its mission statement, which is "to augment soldiers and combat systems by developing and demonstrating practical, cost effective, autonomous intelligent systems capable of completing military missions in complex operating environments. " The mobility requirement for ground-based mobile systems operating in urban settings must increase significantly if robotic technology is to augment human efforts in these roles and environments. The intelligence required for autonomous systems to operate in complex environments demands advances in many fields of robotics. This has resulted in large bodies of research in areas of perception, world representation, and navigation, but the problem of locomotion in complex terrain has largely been ignored. In order to achieve its objective, the Autonomous Intelligent Systems Section is pursuing research that explores the use of intelligent mobility algorithms designed to improve robot mobility. Intelligent mobility uses sensing, control, and learning algorithms to extract measured variables from the world, control vehicle dynamics, and learn by experience. These algorithms seek to exploit available world representations of the environment and the inherent dexterity of the robot to allow the vehicle to interact with its surroundings and produce locomotion in complex terrain. The primary focus of the paper is to present the intelligent mobility research within the framework of the research methodology, plan and direction defined at Defence R&D Canada - Suffield. It discusses the progress and future direction of intelligent mobility research and presents the research tools, topics, and plans to address this critical research gap. This research will create effective intelligence to improve the mobility of ground-based mobile systems operating in urban settings to assist the Canadian Forces in their future urban operations.
Radar retro-reflective patch for vehicle convoying applications

A retro-reflective patch antenna has been developed for radar-based vehicle following. Radar scattering from vehicles is strongly angle dependent at frequencies of practical interest, which complicates tracking. The antenna described here provides a strong, angle independent return that can be used as a stable aiming point. The antenna is a planar Van Atta array of dipoles with a multilayer stripline feed. The antenna's size is comparable to a license plate, and it can be directly attached to the back wall of a van or truck. A description of the antenna's design issues and measurements of its RCS are presented. The antenna described here is a microwave analog of the optical retro-reflector, and we expect it to find applications in many areas.

Genetics of social anxiety disorder: a systematic review

Social anxiety disorder (SAD) is a common psychiatric disorder, often associated with avoidant temperament. Research studies have implicated a strong genetic architecture of SAD. We have conducted a systematic review on the genetics of SAD and yielded 66 articles. In general, prior research studies have focused on the serotonin transporter, oxytocin receptor, brain-derived neurotrophic factor and catechol-O-methyltransferase genes. Mixed and inconsistent results have been reported. Additional approaches and phenotypes have also been investigated, including pharmacogenetics of treatment response, imaging genetics and gene-environment interactions. Future directions warrant further international collaborative efforts, deep-phenotyping of clinical characteristics including consistent and reliable measurement-based symptom severity, and larger sample sizes to ensure sufficient power for stratification due to the heterogeneity of this chronic and often debilitating condition.
Experiment for validation of numerical models of coupled heat and mass transfer around energy cables

The increasing decentralization of electrical energy production as well as an increasing number of fluctuating regenerative energy sources require significant investments in grid expansion. Among other assessments, an exact prediction of the thermal behavior of the cable environment is necessary to be able to design cable routes both technically and economically sufficient. To investigate the coupled thermal and hydraulic processes around a cable‐like heat source with high temporal and spatial resolution under controlled boundary conditions, a cylindrical laboratory test was designed and experiments with two soils conducted. The data collected can be used to validate models of coupled heat and mass transfer around power cables. Within this study, the experimental data was compared with a modified model approach that is based on experimentally determined input data for the thermal and hydraulic properties of the examined soils. Although overall good agreement in the temperature field around the central heat source was observed, differences in the spatial distribution of the dry‐out zone near the heat source led to some shift between the measured and simulated temperatures.
Developing an understanding of research principles to support post-graduate education in the built environment

Most research universities require some combination of standardized classroom teaching and independent research as part of a post-graduate level plan of study. Increasingly construction management, construction technology, architecture, and related programmes that award degrees related to the built environment (BE) are awarding post-graduate degrees. Frequently these degrees, unlike traditional engineering degrees which test theory from a quantitative or positivist position, relate to issues that are more difficult to measure using strictly quantifiable metrics. Because the managerial issues faced by these graduates deal with human interaction and behaviour, research in the BE often resembles social science research to a greater degree than traditional scientific research. As post-graduate programmes in the BE expand, there is an increasing need for student support in the research fundamentals that are required to complete valid research on construction and design issues. Small programmes can rely on the individual mentorship of students, but as student populations grow a more formalized approach is needed to support varying research methodologies employed by post-graduate students as they complete their thesis or dissertation obligations. This paper is an examination of the research fundamentals approach to post-graduate education being used by construction related research programmes in a sample of universities in the US and the UK/Ireland. Emphasis was placed on understanding the current educational support for the understanding of research fundamentals critical to research in the built environment. The paper utilizes both a literature review and a survey instrument. Specific areas of examination include information detailing the educational unit(s) within the university with responsibility for teaching research fundamentals, research fundamentals courses available, the research philosophy or approach emphasized, and the text or other literature support utilized to advance valid research design by post-graduate students. As academic processes develop at post-graduate level there appears to be a consensus that the need for research principles courses is accepted. Where the position differs is at what level this course should be offered.
Shifting Sands and Shifting Grounds: Analysis and Implications of Shifting Dynamics in the Global Construction Industry

AbstractThe global construction industry is in a state of change. The largest construction companies are tracked annually by Engineering News Record (ENR) in the Top 225 Global Contractors list. In the late 1990s this chart was topped by Japanese firms; in the 2000s a French firm held the number-one spot for nine consecutive years. For the last three years, however, Chinese firms have held the top three largest global contractor positions on the list. This is surprising because, just 5 years earlier, none of these Chinese firms were even among the top 10 largest global contractors. To examine these shifting dynamics, the authors compiled the ENR Top 225 Global Contractor data from 1994 to 2011 into a database and analyzed the data. The data were fitted to generate a forecast of predicted changes in market leadership and industry sector shifts to understand the evolving dynamics further. The paper concludes with a discussion of the effects of these critical industry trends to help decision makers understan.
Network reliability with deteriorating product and production capacity through a multi-state delivery network

Delivery process is a critical issue from the viewpoint of supply chain management. However, in the delivery process, deterioration would occur because of natural disasters (e.g. earthquake, fire, flood, hurricane and landslide) or man-made factors (e.g. explosion, terrorist attack and vehicular collision). The results in the intact products arriving at the market may not satisfy the demand. This paper thus concentrates on a multi-state delivery network (MSDN) with multiple suppliers, in which a vertex denotes a supplier, a transfer station or a market, while a branch denotes a carrier providing the delivery service for a pair of vertices. The available capacity of the carrier responsible for the delivery on a branch is multi-state because the capacity may be partially reserved by other customers. The addressed problem is to evaluate the network reliability, the probability that the MSDN with the deterioration consideration can satisfy the market demand within the budget and production capacity limitations. An algorithm is developed in terms of minimal paths to evaluate the network reliability along with a numerical example to illustrate the solution procedure. A real case study of the deteriorating auto glass is utilised to demonstrate the utility of the proposed algorithm.
