SiOx‐Based Probabilistic Bits Enabling Invertible Logic Gate for Cryptographic Applications
Advanced Intelligent Systems, EarlyView.To enable lightweight hardware encryption and decryption, a Ti/SiOx/Ti threshold switching device is engineered to generate controllable stochastic oscillations. By tuning the input voltage, the device produces a programmable spike probability governed by intrinsic switching dynamics, enabling probabilistic bits that construct an invertible ...

Fast hash functions and convolution product
Journal of Mathematical Cryptology, 2014 We propose a new simple and efficient family of hash functions based on matrix-vector multiplications with a competitive software implementation. The hash design combines a hard mathematical problem based on solving a system of linear equations with ...

American Journal of Medical Genetics Part A, EarlyView.ABSTRACT There is a strong genetic contribution to the etiology of congenital diaphragmatic hernia (CDH). This study evaluated genetic testing results and diagnostic yield for fetuses and children with CDH. This was a retrospective cohort study of exome sequencing (ES) performed at GeneDx for fetuses and children ≤ 18 years of age with CDH compared ...

Blockchain Technology and the Circular Economy Transition: Associations With Company Performance
Business Strategy and the Environment, EarlyView.ABSTRACT The adoption of circular economy (CE) practices in the private sector has received increasing academic and managerial attention, although the implementation of such practices continues to face significant barriers. Among Industry 4.0 technologies, blockchain has been identified as a potential factor associated with the CE transition.

Balanced Families of Perfect Hash Functions and Their Applications [PDF]
, 2007 The construction of perfect hash functions is a well-studied topic. In this paper, this concept is generalized with the following definition. We say that a family of functions from $[n]$ to $[k]$ is a $\delta$-balanced $(n,k)$-family of perfect hash ...
