In this paper,we proposed a efficient and laconic mode for iterative hash functions and tried to fix the flaws of the Merkle-Damgaard construction completely and certainly tried to prevent varieties of those generic attacks ,such as Multicollisions Attack,Second Preimage Attack and Herding Attack.The structure of this new mode is different from HAIFA or any other proposal,it contains a new meth...

Stream habitat assessments are conducted to evaluate biological potential, determine anthropogenic impacts, and guide restoration projects. Utilizing these procedures, managers must first select a representative stream reach, which is typically selected based on several criteria. To develop a consistent and unbiased procedure for choosing sampling locations, the Illinois Department of Natural R...

It is commonly thought that neurons in monkey inferotemporal cortex are conjunction selective--that a neuron will respond to an image if and only if it contains a required combination of parts. However, this view is based on the results of experiments manipulating closely adjacent or confluent parts. Neurons may have been sensitive not to the conjunction of parts as such but to the presence of ...

PURPOSE A "dose bricks" concept has been used to implement nasopharyngeal carcinoma treatment plan; this method specializes particularly in the case with bell shape nasopharyngeal carcinoma case. MATERIALS AND METHODS Five noncoplanar fields were used to accomplish the dose bricks technique treatment plan. These five fields include (a) right superior anterior oblique (RSAO), (b) left superior...

Abstract Funding Acknowledgements Type of funding sources: None. Background Anatomical variations and characteristics the left atrium (LA) may have a previously undescribed effect on source locations in atrial fibrillation (AF). Electrographic flow (EGF) mapping is novel method used to estimate cardiac action potential atria that can detect AF sources patients with persistent AF. The EGF techno...

We study axisymmetric thermomechanical deformations of a thick target being penetrated by a fast-moving rigid cylindrical rod with a hemispherical nose, and presume that target deformations appear steady to an observer situated at the penetrator nose tip. Both isotropic and kinematic hardening of the target material are considered. It is found that kinematic hardening increases the normal stres...
