Nonconcentration of return times
, 2013 We show that the distribution of the first return time $\tau$ to the origin, v, of a simple random walk on an infinite recurrent graph is heavy tailed and nonconcentrated.

Collision-resistant hash-shuffles on the reals
Oneway real functions are effective maps on positive-measure sets of reals that preserve randomness and have no effective probabilistic inversions. We construct a oneway real function which is collision-resistant: the probability of effectively producing distinct reals with the same image is zero, and each real has uncountable inverse image.

Covalently‐Bonded Diaphite Nanoplatelet with Engineered Electronic Properties of Diamond
Advanced Functional Materials, EarlyView.A novel approach to engineering the electronic properties of diamond is reported on the diaphite nanoplatelet consisting of (11¯${{\bar{1}}}$1) planes of diamond nanoplatelet covalently bonded with graphite (0001) planes. The strong sp3/sp2‐hybridized interfacial covalent bonding induces the electron transfer from diamond to graphite, resulting in a ...

Safety analysis of hull (platform) operation in Bohai sea ice area
Zhongguo Jianchuan Yanjiu, 2020 Objectives When an offshore nuclear power platform operates in the Bohai Sea area, it faces a threat from floating ice in winter. Therefore, for the sake of safety, it is necessary to analyze the collision process between the floating ice and the ...

Continuous-variable quantum authentication of physical unclonable keys
, 2017 We propose a scheme for authentication of physical keys that are materialized by optical multiple-scattering media. The authentication relies on the optical response of the key when probed by randomly selected coherent states of light, and the use of ...

Advanced Functional Materials, EarlyView.Bi‐directionally assembled BN µ‐platelets in micropatterns formed by a micro‐molding method for thermal interface materials are demonstrated. The BN µ‐platelets are vertically aligned selectively, while compressed regions without patterns accommodate horizontally assembled BN µ‐platelets. Through anisotropic orientation, high thermal conductivities for

Ship structure collision experiments and simplified numerical calculation method
Zhongguo Jianchuan YanjiuObjectivesAlthough the fluid-structure interaction calculation method can better simulate the ship collision process, it requires a longer calculation time. To address this problem, a simplified numerical calculation method is proposed.

On the Design of Secure and Fast Double Block Length Hash Functions [PDF]
, 2008 In this work the security of the rate-1 double block length hash functions, which based on a block cipher with a block length of n-bit and a key length of 2n-bit, is reconsidered.

Development of an Anti-collision Model for Vehicles
, 2012 The Anti Collision device is a detection device meant to be incorporated into cars for the purpose of safety. As opposed to the anti collision devices present in the market today, this system is not designed to control the vehicle.
