Since Bellare and Ristenpart showed a multi-property preserving domain extension transform, the problem of the construction for multi-property hash functions has been reduced to that of the construction for multi-property compression functions. However, the Davies-Meyer compression function that is widely used for standard hash functions is not a multi-property compression function. That is, in...

To obtain the acceleration characteristics of frictional collision between potato and rod, reveal mechanism peel damage, a test rig was designed to conduct si...

The operation of any vessel includes risks, such as mechanical failure, collision, property loss, cargo or damage. For modern container ships, safe navigation is challenging the rate innovation regarding design, speed profiles, and carrying capacity has experienced exponential growth over past few years. Prevention loss in ship liners high importance for Maritime industry waterborne sector it c...

We consider protective structures with elastic-plastic links of a special morphology. The links are bistable: they are designed to arrest the development of localized damage (a neck) in an element, initiating the damage instead in another sequential element. A wave of “partial damage” propagates through the chain, as all the links develop necks but do not fail. When subjected to an impact, such...

Low-frequency properties of a plasma are examined within the average-atom approximation, which presumes that scattering of a conducting electron on each atom takes place independently of other atoms. The relaxation time tau distinguishes a high-frequency region omegatau>1 , where the single-atom approximation is applicable explicitly, from extreme low frequencies omegatau<1 , where, naively, th...

treatment of diseases with natural remedies is gaining popularity because of its fewer side effects.   a systemic and scientific investigation of aqueous extract of euphorbia tirucalli for its antioxidant and hepatoprotective potential against carbon-tetrachloride-induced hepatic damage in rats was carried out . antioxidant property was assessed by using reducing property, superoxide anion scav...

Focused Ion Beam (FIB) has been demonstrated as a promising tool to the fabrication of microand nanoscale diamond cutting tools. In-depth understanding of the ion-solid interaction in diamond leading to residual damage under different processing parameters are in high demand for the fabrication of nanoscale diamond tools. Molecular dynamics (MD) simulation method has long been regarded as a pow...
