Hyperovals in Knuth’s binary semifield planes

open access: yesEuropean Journal of Combinatorics, 2017
In each of the three projective planes coordinatised by the Knuth's binary semifield $\mathbb{K}_n$ of order $2^n$ and two of its Knuth derivatives, we exhibit a new family of infinitely many translation hyperovals. In particular, when $n=5$, we also present complete lists of all translation hyperovals in them. The properties of some designs associated

Sublethal Effects of Four Insecticides Targeting Cholinergic Neurons on Partner and Host Finding in the Parasitic Wasp Nasonia vitripennis

open access: yesEnvironmental Toxicology and Chemistry, Volume 42, Issue 11, Page 2400-2411, November 2023., 2023
Abstract Lethal and sublethal effects of pesticides on nontarget organisms are one of the causes of the current decline of many insect species. However, research in the past decades has focused primarily on pollinators, although other beneficial nontarget organisms such as parasitic wasps may also be affected.

Effects of radiation on the fitness, sterility and arbovirus susceptibility of a Wolbachia‐free Aedes albopictus strain for use in the sterile insect technique

open access: yesPest Management Science, Volume 79, Issue 11, Page 4186-4196, November 2023., 2023
A Wolbachia‐free Aedes albopictus strain was developed and considered to be used for SIT programmes based on the comparable fitness cost, radiosensitivity and arbovirus susceptibility to its conspecifics. Abstract BACKGROUND The sterile insect technique (SIT) is a green and species‐specific insect pest control technique that suppresses target ...

8 semifield planes of order 82

open access: yesDiscrete Mathematics, 1990
The authors work out a list of all eight translation planes of order 64 which contain GF(8) in its kernel and have a collineation group of order 128. By a result of \textit{M. Biliatti}, \textit{V. Jha}, the second author and \textit{G. Menichetti} [Geom. Dedicata 29, No.1, 7-43 (1989; Zbl 0673.51003)] they are all semifield planes.

On automorphisms of semifields and semifield planes

open access: yesSibirskie Elektronnye Matematicheskie Izvestiya, 2016
Изучается взаимосвязь полуполевой проективной плоскости и ее координатизирующего полуполя с использованием линейного пространства и регулярного множества. Установлен геометрический смысл инволюторного автоморфизма конечного полуполя, доказаны некоторые его свойства.

On translation hyperovals in semifield planes

open access: yesDesigns, Codes and Cryptography
In this paper we demonstrate the first example of a finite translation plane which does not contain a translation hyperoval, disproving a conjecture of Cherowitzo. The counterexample is a semifield plane, specifically a Generalised Twisted Field plane, of order $64$. We also relate this non-existence to the covering radius of two associated rank-metric

Molecular and Functional Insights Into the Avian Gut Microbiota: Roles in Health, Disease Resistance, and Microbiome Modulation

open access: yesAdvanced Gut &Microbiome Research, Volume 2026, Issue 1, 2026.
The avian gut microbiota constitutes a complex, multiphyla ecosystem that critically shapes host physiology, immune function, disease resistance, and antimicrobial resistance dynamics. Bacteria, archaea, fungi, and viruses collectively regulate nutrient metabolism, mucosal barrier integrity, and immunological maturation, whereas dysbiosis increases ...

p-primitive semifield planes [PDF]

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1992
Publisher Summary This chapter present a study of the class of semifield planes of order p4 and kernel GF(p2) with the property that they admit a p-primitive Baer collineation; these are called “p-primitive semifield planes.”This is the class of planes obtained when the construction method of Hiramine, Matsumoto, and Oyama is applied to the ...
