objective(s):one cause of cigarette smoking is oxidative stress that may alter the cellular antioxidant defense system, induce apoptosis in lung tissue, inflammation and damage in liver, lung, and kidney. it has been shown that chinese green tea (cgt) (lung chen tea) has higher antioxidant property than black tea. in this paper, we will explore the preventive effect of cgt on cigarette smoke-in...

Collision accidents may lead to significant asset damage and human casualties. This paper introduces a direct analysis methodology that makes use of Automatic Identification System (AIS) data estimate collision probability generate scenarios for in ship stability assessment. Potential are detected from AIS by an avoidance behaviour-based detection model (ABCD-M) the is estimated various routes ...

We present an accurate measurement and a quantitative analysis of electron-beam-induced displacements of carbon atoms in single-layer graphene. We directly measure the atomic displacement ("knock-on") cross section by counting the lost atoms as a function of the electron-beam energy and applied dose. Further, we separate knock-on damage (originating from the collision of the beam electrons with...

Abstract In this study, we first performed a comprehensive structural analysis of four models radiosondes (devices intended for use as the meteorological probe sounding balloon) manufactured by three different companies – Graw, Vaisala and Meteomodem. The were disassembled visual inspection manual measurement, three-dimensional computed tomography images taken their inner structure, outer shape...

in recent research on modelling road collisions very little attention has been paid  to rear-end chain reaction collisions, which is characterized by more than two vehicles involved in a collision at the same time. the core aim of the present research is to develop a methodology to estimate such potential collision probabilities based on a proactive perspective, where deceleration rate to avoid...

The development of accurate and fast algorithms for the Boltzmann collision integral and their analysis represent a challenging problem in scientific computing and numerical analysis. Recently, several works were devoted to the derivation of spectrally accurate schemes for the Boltzmann equation, but very few of them were concerned with the stability analysis of the method. In particular there ...

Certificateless signature scheme becomes a most attractive area for researchers to provide a lot of potential to secure network against malicious adversaries. Aggregate signature is a many to one map that allows mapping n users signature in to single short signature. Aggregate signatures reduce the bandwidth used in the network which is useful in many practical areas where bandwidth is a major ...

We present new attacks on the Feistel network, where each round function consists of a subkey XOR, S-boxes, and then a linear transformation (i.e., an SP round function). Our techniques are based largely on what they call the rebound attacks. As a result, our attacks work most effectively when the S-boxes have a “good” differential property (like the inverse function x 7→ x−1 in the finite fiel...
