Challenges and opportunities in mitigating sarcoptic mange in wild South American camelids
The Journal of Wildlife Management, EarlyView.Wild South American camelids—vicuña and guanaco—face threats from sarcoptic mange, a contagious skin disease linked to severe population declines. Despite its impact, major gaps remain in understanding disease dynamics. This review summarizes current knowledge, identifies key data and management gaps, and outlines urgent actions for effective ...

Verifiable Random Functions (VRFs) [PDF]
, 2018 A Verifiable Random Function (VRF) is the public-key version of a keyed cryptographic hash. Only the holder of the private key can compute the hash, but anyone with public key can verify the correctness of the hash.

On the Indifferentiability of the Grøstl Hash Function [PDF]
, 2010 The notion of indifferentiability, introduced by Maurer et al., is an important criterion for the security of hash functions. Concretely, it ensures that a hash function has no structural design flaws and thus guarantees security against generic attacks up to the proven bounds. In this work we prove the indifferentiability of Grostl, a second round SHA-

Cryptanalysis of the GOST Hash Function [PDF]
, 2008 In this article, we analyze the security of the GOST hash function. The GOST hash function, defined in the Russian standard GOST 34.11-94, is an iterated hash function producing a 256-bit hash value. As opposed to most commonly used hash functions such as MD5 and SHA-1, the GOST hash function defines, in addition to the common iterative structure, a ...

Alternating‐contrast single‐shot spiral MR‐ARFI with model‐based displacement map reconstruction
Magnetic Resonance in Medicine, EarlyView.Abstract Purpose To improve single‐shot spiral MR‐Acoustic Radiation Force Imaging (MR‐ARFI)'s robustness to dynamic phase errors and evaluate it in non‐human primates (NHPs) with a low‐f‐number transducer. Methods A single‐shot spiral MR‐ARFI pulse sequence with 2 mm in‐plane resolution and alternating displacement phase contrast was implemented to ...

Hash Embeddings for Efficient Word Representations
, 2017 We present hash embeddings, an efficient method for representing words in a continuous vector form. A hash embedding may be seen as an interpolation between a standard word embedding and a word embedding created using a random hash function (the hashing ...

A Digital Phantom for MR Spectroscopy Data Simulation
Magnetic Resonance in Medicine, EarlyView.ABSTRACT Purpose Simulated data is increasingly valued by researchers for validating MRS processing and analysis algorithms. However, there is no consensus on the optimal approaches for simulation models and parameters. This study introduces a novel MRS digital brain phantom framework, providing a comprehensive and modular foundation for MRS data ...
