Bandwidth-Hard Functions from Random Permutations [PDF]
arXiv, 2022 ASIC hash engines are specifically optimized for parallel computations of cryptographic hashes and thus a natural environment for mounting brute-force attacks on hash functions. Two fundamental advantages of ASICs over general purpose computers are the area advantage and the energy efficiency.

Architected Lattices with a Topological Transition
Advanced Engineering Materials, EarlyView., 2023 This article develops topological metamaterials showing multidirectional two‐step deformation under compression by embedding contact‐enabled topological mechanisms into lattice structures. Experiments on 3D‐printed 2D and 3D lattices and finite element simulations are conducted to demonstrate the working principle of the topological metamaterials.

The influence of the vanadium content on the toughness and hardness of wear resistant high-alloyed Cr-Mo steel [PDF]
FME Transactions, 2017 Characteristics of air hardening steel are high hardness and low impact toughness. In order to increase the impact toughness while retaining high hardness value, studies were performed.
