British Journal of Clinical Pharmacology, EarlyView.Aim A prior non‐randomized study suggests that potassium supplementation may improve survival among furosemide initiators, and a randomized trial suggests that salt substitutes containing potassium might lower stroke risk. We conducted a retrospective cohort study using health‐care data to confirm or refute these associations among new users of ...

Chemistry – A European Journal, EarlyView.Machine‐learning potentials are increasingly taking on the exploratory tasks of homogeneous catalysis, enabling rapid conformer sampling and reaction‐space mapping. However, when selectivity depends on subtle electronic effects, electronic‐structure methods remain essential.

Weakened Random Oracle Models with Target Prefix [PDF]
, 2019 Weakened random oracle models (WROMs) are variants of the random oracle model (ROM). The WROMs have the random oracle and the additional oracle which breaks some property of a hash function. Analyzing the security of cryptographic schemes in WROMs, we can specify the property of a hash function on which the security of cryptographic schemes depends ...

Partial identification with categorical data and nonignorable missing outcomes
Canadian Journal of Statistics, EarlyView.Abstract Nonignorable missing outcomes are common in real‐world datasets and often require strong parametric assumptions to achieve identification. These assumptions can be implausible or untestable, and so we may wish to forgo them in favour of partially identified models that narrow the set of a priori possible values to an identification region.

Short Signatures in the Random Oracle Model [PDF]
, 2002 We study how digital signature schemes can generate signatures as short as possible, in particular in the case where partial message recovery is allowed. We give a concrete proposition named OPSSR that achieves the lower bound for message expansion, and give an exact security proof of the scheme in the ideal cipher model.

Formal Indistinguishability Extended to the Random Oracle Model [PDF]
, 2009 Several generic constructions for transforming one-way func-tions to asymmetric encryption schemes have been proposed. One-way functions only guarantee the weak secrecy of their arguments. That is, given the image by a one-way function of a random value, an adversary has only negligible probability to compute this random value. Encryp-tion schemes must

The equivalence of the random oracle model and the ideal cipher model, revisited [PDF]
Proceedings of the forty-third annual ACM symposium on Theory of computing, 2011 We consider the cryptographic problem of constructing an invertible random permutation from a public random function (i.e., which can be accessed by the adversary). This goal is formalized by the notion of indifferentiability of Maurer et al. (TCC 2004).

Nonlinear permuted Granger causality
Canadian Journal of Statistics, EarlyView.Abstract Granger causality is an established, contentious method that seeks causal temporal connections via association and precedence. While not true causal inference, it assists in mapping networks of information flow that may warrant further study.

Two improved content extraction signature schemes
网络与信息安全学报, 2017 Motivated by the idea of batch signatures,two variants of content extraction signature schemes based on commit vector and RSA respectively were presented.In the proposed schemes,the efficiency of signing and verification were improved by unifying certain
