Tropical Solution of Discrete Best Approximation Problems
We consider discrete best approximation problems in the setting of tropical algebra, which is concerned with the theory and application of algebraic systems with idempotent operations. Given a set of input–output pairs of an unknown function defined on a

Semi-field and indoor setups to study malaria mosquito swarming behavior
Background The recent resurgence of interest in sterile insect techniques to control vector mosquitoes has renewed interest in novel methods for observing mating behavior.

On the multiplication groups of semifields
The multiplication group of a loop is the permutation group generated by all right and left multiplications of the loop. The author uses finite semifields (i.e. non-associative division algebras) to obtain loops whose multiplication groups are between \(\text{PSL}(n,q)\) and \(\text{PGL}(n,q)\), for \(n\geq 3 \) and \(q^n>8\); the proof is based on ...

Quantifying the impact of Psylliodes chrysocephala injury on the productivity of oilseed rape
The impact of Psylliodes chrysocephala adult and larval damage on oilseed rape yield was quantified to help develop improved thresholds for Integrated Pest Management. Up to 90% leaf area loss (simulated using a hole punch) during early growth did not affect yield.

Breaking the beetle barrier: Innovative strategies for controlling Hylurgus ligniperda in China
Hylurgus ligniperda is a major quarantine pest of forest trees in China. Exploring emergency control techniques in the field can effectively avoid large outbreaks and the spread of H. ligniperda. In this study, H.

Central Weak Nucleus Semifields
Using results of S. D. Cohen and the author, we characterize certain infinite families of finite semifields. This yields several infinite families of finite projective planes, all of which have order a power of 3, and which appear to be previously unknown.

Experimental arena settings might lead to misinterpretation of movement properties
Many studies examine movement in the laboratory and use different laboratory conditions, specifically arenas differing in structure, size, and shape. We examined the effect of the arena structure on movement properties using the red flour beetle as a model. The arena structure greatly affected movement properties, such as movement distance, turn angles,

Non-Apis bees as model organisms in laboratory, semi-field and field experiments
As part of the registration process of plant protection products (PPPs) and their active substances in the EU, the risk of PPPs for bees has been assessed so far by using the European honey bee (Apis mellifera L.) as a surrogate species.

Abstract Hoverfly larvae are voracious predators of aphids but have limited dispersal capacity, so their survival depends critically on female selection of oviposition sites. For aphid control purposes, the ability of females to find small aphid colonies is especially valuable.
