Phenobot: An Autodigital Modeling System for in situ Phenotyping in Horticulture

Advanced Intelligent Systems, EarlyView.
This study introduces a robotic phenotyping system for precision agriculture, integrating environmental understanding, motion planning, and in situ plant phenotyping. The system autonomously navigates through real‐world agricultural environments, collects high‐quality plant data, and reconstructs accurate 3D plant models. Results demonstrate the system'

Haraka v2 – Efficient Short-Input Hashing for Post-Quantum Applications

IACR Transactions on Symmetric Cryptology, 2017
Recently, many efficient cryptographic hash function design strategies have been explored, not least because of the SHA-3 competition. These designs are, almost exclusively, geared towards high performance on long inputs.

Sustainability‐inspired upcycling of organophosphorus pollutants into phosphatic fertilizer on continuous‐flow reactor

Angewandte Chemie International Edition, Accepted Article.
With the increasing requirement for phosphorus resources and their shortage in nature, cyclic utilization of organophosphorus pollutants into phosphatic fertilizer might offer a sustainable approach to achieve the recycling of phosphorus. Herein, we first report the selective degradation of organophosphorus pollutants (such as HEDP and glyphosate), via

Using a combination of midazolam and butorphanol is a safe and effective reversible field sedation protocol for Weddell seal (Leptonychotes weddellii) pups

Veterinary Record, Volume 191, Issue 11, 3/10 December 2022., 2022
Abstract Background Weddell seals (Leptonychotes weddellii) are a well‐studied species of phocid with an apparent sensitivity to immobilising agents. Mortality as high as 31% has been reported during field immobilisation. This study investigated the use of a benzodiazepine in combination with an opioid agonist/antagonist for sedation in Weddell seal ...

A Fast Single-Key Two-Level Universal Hash Function

IACR Transactions on Symmetric Cryptology, 2017
Universal hash functions based on univariate polynomials are well known, e.g. Poly1305 and GHASH. Using Horner’s rule to evaluate such hash functionsrequire l − 1 field multiplications for hashing a message consisting of l blocks where each block is one ...

A Needle in a Haystack: Landscape Survey and Archaeological Detection Experiments in Apalachee Bay

Archaeological Prospection, EarlyView.
ABSTRACT This paper presents the results of a pilot landscape‐scale seismic survey undertaken in Apalachee Bay, Florida, across a submerged landscape that contains dozens of Pre‐Contact sites. In addition to the goals of improving the geophysical and remote sensing ground model for this submerged landscape, the survey also sought to undertake the first

Open problems in hash function security [PDF]

Designs, Codes and Cryptography, 2015
A cryptographic hash function compresses arbitrarily long messages to digests of a short and fixed length. Most of existing hash functions are designed to evaluate a compression function with a finite domain in a mode of operation, and the compression function itself is often designed from block ciphers or permutations.

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 ...
