Spreading of turbulence as a result of nonlinear mode couplings and the associated spectral energy transfer is studied. A derivation of a simple two-field model is presented using the weak turbulence limit of the two-scale direct interaction approximation. This approach enables the approximate overall effect of nonlinear interactions to be written in the form of Fick’s law and leads to a couple...
Background: During intensity modulated radiation therapy (IMRT) technique, theoretically, presence of flattening filter (FF) across the beamline of clinical linear accelerator (linac) is not essential to obtain uniform lateral profiles due to intensity modulation of photon beams by multileaf collimators (MLCs). The aim of this study was to investigate the dosimetrical properties of 18 MV photon...

E-mail address: [email protected] (N.N. Kacho This paper addresses the quantification of glacier retreat through remote sensing. Specifically, we use multi-spectral Landsat satellite images for the estimation of glacier termi...
We present a statistical model for the delay profile of ultra-wideband channels in indoor environments. Two kinds of profiles are defined, namely the multipath intensity profile (MIP) and the power delay profile (PDP). The MIP is he delay profile at a point in space, while the PDP is a local spatial average. The model is based on 60,000 complex frequency response measurements from 20 commercial...
A simple analytical ansatz, which has been used to describe the intensity profile of the similariton laser a laser with self-similar propagation of ultrashort pulses , is used as a variational wave function to solve the Gross-Pitaevskii equation for a wide range of interaction parameters. The variational form interpolates between the noninteracting density profile and the strongly interacting T...
Introduction: Type 2 diabetes (T2D) causes hyperglycemia, hyperinsulinemia, and dyslipidemia, which are all risk factors for atherosclerosis. Lipoprotein-associated phospholipase A2 (Lp-PLA2) has been recognized as an indicator of atherosclerosis due to its role in vessel inflammation. This study aimed to investigate the effect of high-intensity interval training (HIIT) on serum levels of Lp-PL...
Background and Objectives: Lack of physical activity is a worrying condition because it leads to major health problems such as obesity, high blood pressure and various metabolic disorders. Exercise is a lifestyle change suggested to reduce atherogenic markers in adults. Increased physical activity and fitness are clearly associated with a reduced risk of cardiovascular disease, but the optimal ...
Background: Labor is a natural pain despite the fact that the severity of the pain and response to it differ in various people, but most women refer to labor as an unpleasant experience of their lives. The present study was carried out to determine the effect of honey on the severity of labor in primigravida women. Methods: In this study, 80 healthy volunteer primigravida women were entered to...
