In the case of a rarefaction fan in a non-stationary Hammersley process, we explicitly calculate the asymptotic behavior of the process as we move out along a ray, and the asymptotic distribution of the angle within the rarefaction fan of a second class particle and a dual second class particle. Furthermore, we show that a second class particle and a dual second class particle touch with probab...
In this paper, we theoretically show that the field-free molecular orientation created by a single dual-color laser pulse can be significantly enhanced by separating it into two time-delayed dual-color subpulses. It is indicated that the maximum enhancement of the molecular orientation created by two time-delayed dual-color subpulses can be achieved with their intensity ratio of about 1:2 and b...
Fast ignition is a new method for inertial confinement fusion (ICF) in which the compression and ignition steps are separated. In the first stage, fuel is compressed by laser or ion beams. In the second phase, relativistic electrons are generated by pettawat laser in the fuel. Also, in the second phase 5-35 MeV protons can be generated in the fuel. Electrons or protons can penetrate in to the u...
A pair of Wolfe type non-differentiable second order symmetric primal and dual problems in mathematical programming is formulated. The weak and strong duality theorems are then established under second order F-convexity assumptions. Symmetric minimax mixed integer primal and dual problems are also investigated. 2002 Elsevier Science B.V. All rights reserved.
Background and Aim: Microleakage has been always a major concern in restorative dentistry. The curing contraction of composites still presents a problem with controlling microleakage and postoperative sensitivity. The aim of this study was to investigate the effect of flowable and dual-cure resin composite liners on gingival microleakage of packable resin composite restorations. Materials and ...
Introduction: The advent of dual-modality PET/CT scanners has revolutionized clinical oncology by improving lesion localization and facilitating treatment planning for radiotherapy. In addition, the use of CT images for CT-based attenuation correction (CTAC) decreases the overall scanning time and creates a noise-free attenuation map (6map). CTAC methods include scaling, s...
This paper extends the dual calculus with inductive types and coinductive types. The paper first introduces a non-deterministic dual calculus with inductive and coinductive types. Besides the same duality of the original dual calculus, it has the duality of inductive and coinductive types, that is, the duality of terms and coterms for inductive and coinductive types, and the duality of their re...
In this study we examined how the introduction of a parallel finger-tapping task influences second language speech (L2) encoding mechanisms and monitoring processes and how the level of proficiency impacts the efficiency and accuracy of L2 performance under single and dual task conditions. The results indicated that imposing dual task demands has a negative effect on the accuracy of lexical sel...
متامتریال یا فراماده یک ساختارمصنوعی وهمگن است که خواص غیرعادی الکترومغناطیس ازخود نشان میدهد.مواد دست چپی که دارای εو μمنفی میباشند،دارای خواص فراماده میباشند.اما مواد دست چپی خالص را نمیتوان ایجادکرد؛ به دلیل وجودعناصرپارازیتیک درفرکانس های بالا،همواره ترکیبی ازمواد دست راستی و دست چپی وجود داردکه به آنها crlh میگویند. به دلیل خواص منحصربه فردی که خطوط دست چپی از خود نشان میدهند،میتوان درطراح...
