Abstract. A composite dilation Parseval frame wavelet is a collection of functions generating a Parseval frame for L2(Rn) under the actions of translations from a full rank lattice and dilations by products of elements of groups A and B. A minimally supported frequency composite dilation Parseval frame wavelet has generating functions whose Fourier transforms are characteristic functions of set...
Broadband satellite systems will need specific functions and interfaces in order to fit seamlessly into an endto-end Next Generation Network (NGN) Quality of Service (QoS) architecture. This paper will define NGN overall architecture, showing how the coupling between Application/session layers and Network/transport layers can achieve end-to-end QoS support. Possible integration scenarios of sat...
This paper presents a contactless measurement method for antenna radiation efficiency estimation within reverberation chambers (RCs). does not require to connect any analyzer the under test (AUT). The AUT is obtained from differential of RC composite $Q$-factor estimated two load conditions, namely an open circuit and \SI[detect-weight]{50}{\ohm} load. Remotely-controlled RF switches are used i...
Renshaw cells (RCs) receive excitatory inputs from motoneurons to which then they inhibit. The gain of this spinal recurrent inhibitory circuit is modulated by inhibitory synapses on RCs. Inhibitory synapses on RCs mature postnatally, developing unusually large postsynaptic gephyrin clusters that colocalize glycine and GABA(A) receptors. We hypothesized that these features potentiate inhibitory...
در این پژوهش برای اولین بار از روش های محاسبه ی عددی سطح مقطع راداری (rcs ) در حوزه ی تراهرتز استفاده شده است. مزیت روش های معرفی شده در این پژوهش برای محاسبه ی rcs در حوزه ی تراهرتز این است که می توان اجسام بسیار بزرگ را با مقیاس بندی خیلی کوچک تر کرده و rcs آن ها در فرکانس رادارهای معمولی در رنج ghz 10-1 را بدست آورد. این مقیاس بندی، طراحی، تست و ساخت اجسام با مشخصات خاص راداری را، مانند رادا...
Abstract: The study is to propose the local damage indices of composite frame structures consisting of high-strength concrete columns confined by continuous compound spiral ties and steel beams (CCSTRCS), the local damage indices would lay a foundation for the study of the overall damage indices for composite CCSTRCS frame. The Mehanny damage model has been modified to predict the local damage ...
OBJECTIVES To evaluate the short-term and long-term prognostic impacts of acute phase coronary collaterals to occluded infarct-related arteries (IRA) after ST-elevation myocardial infarction (STEMI) in the percutaneous coronary intervention (PCI) era. DESIGN A prospective observational study. SETTING Osaka Acute Coronary Insufficiency Study (OACIS) in Japan. PARTICIPANTS 3340 patients wit...
PURPOSE To describe the extended Rehabilitation Complexity Scale (RCS-E) and its factor structure, and to determine whether it provides added value over the RCS-version 2 to identify patients with highly complex rehabilitation needs. METHOD A cohort analysis of prospectively-collected routine clinical data from 331 patients with complex neurological disabilities undergoing inpatient rehabilit...
In this paper, nonlinear behavior of strengthened steel plate shear walls (SPSWs) by FRP laminates theoretically and numerically has been investigated. In the first part, a new method, “the composite-plate frame Interaction (C-PFI) method”, has been introduced to predict the shear behavior of the composite steel plate shear wall systems (CSPSWs). In the second part, several models of one-story ...
BACKGROUND Social isolation in medical students is a subjective experience that may influence medical career decision making. Rural self-efficacy has been shown to influence rural career intentions following a rural clinical placement, however its impact on social isolation during a rural clinical placement has not been previously modeled. The objective of this study is to explore whether self-...
