A Mathematical Analysis and Evaluation of Varroa mite Control Methods for a Mite-infested Honey bee Colony [PDF]

open access: yesarXiv, 2022
In this paper, we present a mathematical model for the interaction between honey bees and mites. The dynamics of a mite-infested honey bee colony and the evaluation of the commonly used mite-control strategies (traditional, mechanical and chemical) are studied.

Nest Architecture of the Australian Paper Wasp Ropalidia Romandi Cabeti , With a Note on its Developmental Process (Hymenoptera: Vespidae)

open access: yesPsyche: A Journal of Entomology, 1994
Nest architecture of Ropalidia romandi cabeti was described, based on 2 incipient (an active and an abandoned) nests and 3 developed ones. Developed nests were spherical, or hemispherical when built under flat surfaces, consisted of several to more than ...

Thermal equilibrium of a macroscopic quantum system in a pure state [PDF]

open access: yesPhys. Rev. Lett. 115, 100402 (2015), 2015
We consider the notion of thermal equilibrium for an individual closed macroscopic quantum system in a pure state, i.e., described by a wave function. The macroscopic properties in thermal equilibrium of such a system, determined by its wave function, must be the same as those obtained from thermodynamics, e.g., spatial uniformity of temperature and ...

Orchestration of an uncommon maturation cascade of the house dust mite protease allergen quartet

open access: yesFrontiers in Immunology, 2014
In more than 20% of the world population, sensitization to house dust mite (HDM) allergens triggers typical allergic diseases such as allergic rhinitis and asthma.

Severe Scabies after COVID-19: A Case Report [PDF]

open access: yesInternational Journal of Scientific Research in Dental and Medical Sciences, 2020
Scabies is defined as a pruritic skin condition caused by an infestation of itch mite Sarcoptes scabiei that is exceptionally contagious; however, there is no exact figure on its prevalence. A six-year-old girl was presented to the Dermatology department

A C2-tilde-lattice that is not residually finite [PDF]

open access: yesarXiv, 2023
We construct the first example of a lattice on an irreducible Euclidean building that is not residually finite. Conjecturally, the normal subgroup theorem extends to this lattice making it virtually simple.

Macroscopic and Microscopic Thermal Equilibrium [PDF]

open access: yesAnnalen der Physik 529, 1600301 (2017), 2016
We study the nature of and approach to thermal equilibrium in isolated quantum systems. An individual isolated macroscopic quantum system in a pure or mixed state is regarded as being in thermal equilibrium if all macroscopic observables assume rather sharply the values obtained from thermodynamics.
