Development and Evaluation of a Low‐Cost, Semi‐Automated Camera Trap for Surveying Bumble Bee Communities

Remote Sensing in Ecology and Conservation, EarlyView.
Camera traps are emerging as a useful tool for noninvasive insect monitoring; however, it remains unclear how to lure diurnal insects to traps, how to detect them upon arrival, and how camera‐based methods compare to conventional sampling. We developed a low‐cost, open‐source camera trap to monitor wild bumble bees in agricultural fields. We found that

Dual‐Stimuli Responsive Poly(N‐acryloyl glycine) Microgels: Investigation of Network Structures and Application for Loading and Release of Biologics

Small, EarlyView.
Poly(N‐acryloyl glycine) hydrogel microparticles were fabricated via droplet‐based microfluidics and in situ photopolymerization. Rheology and MQ‐NMR revealed pronounced effects of pH and Ca2+ on network constraints and chain mobility, governing extensive swelling.

Improving String Matching through Enhanced Hashing

Software: Practice and Experience, EarlyView.
ABSTRACT Background Hashing offers opportunities to tune string matching algorithms while enabling efficient data retrieval and pattern detection. Many of the best algorithms apply hashing. Objective We try to develop faster online algorithms for exact string matching.

Recursive Grid Indexing for Fast Non‐Uniform Quantization Without Binary Search

Software: Practice and Experience, EarlyView.
ABSTRACT Purpose To present Recursive Grid Indexing (RGI), a practical software technique for accelerating non‐uniform quantization and predecessor queries without relying on binary search at any stage. Design/Methodology/Approach RGI replaces conventional logarithmic binary search with a recursive, low‐branching grid structure. The method constructs a

Hash function security:cryptanalysis of the Very Smooth Hash and multicollisions in generalised iterated hash functions.

, 2012
Tiivistelmä Viime vuosina digitaaliseen tiedonsiirtoon perustuva tiedonsiirto on yleistynyt valtavasti. Tästä on seurannut monia uusia tietoturvaongelmia. Tässä yhteydessä erityisesti tiedon suojaamiseen käytetyt kryptografiset menetelmät ovat olleet tarkastelun kohteena.

Fixing Ill‐Formed UTF‐16 Strings With SIMD Instructions

Software: Practice and Experience, EarlyView.
ABSTRACT Background We must fix ill‐formed UTF‐16 strings, where surrogate pairs are mismatched. Programming languages such as JavaScript provide functions that replace mismatched surrogates with the Unicode replacement character (U + FFFD). Objectives We seek to accelerate the correction of ill‐formed UTF‐16 strings.

Multicollisions and graph-based hash functions

, 2012
In this paper, we present some generalisations of previous multicollision finding methods and apply these against a new type of tree-based hash functions. We also show that the very general class of hash functions first presented by Nandi and Stinson can

Dietary and Ranging Behavior of Semi‐Free Ranging Lemur catta and Varecia rubra at Myakka City Lemur Reserve, Florida, USA

Zoo Biology, EarlyView.
Betsiboka, a female red ruffed lemur (Varecia rubra) eating Carolina redroot in the Tower forest. ABSTRACT Lemurs are severely threatened due to anthropogenic habitat loss and climate change. Therefore, understanding how lemurs adapt their diets to novel habitats is critically important for maintaining healthy wild populations and effectively managing ...
