Generalized Laurent monomials in nonrational toric geometry [PDF]

open access: yesContemp. Math., 794 (2024), 179-193, 2022
We generalize Laurent monomials to toric quasifolds, a special class of highly singular spaces that extend simplicial toric varieties to the nonrational setting.

Dynamic modelling of a ground-coupled solar ejector cooling system

open access: yesInternational Journal of Sustainable Energy, 2022
This work presents a solar-driven air conditioning system based on ejector technology with closed-loop vertical geothermal boreholes. Modeling and simulation are carried out using Dymola software for dynamic transient analysis, with the refrigerant R134a.

Asymptotic flocking for the Cucker-Smale model with time variable time delays [PDF]

open access: yes, 2022
In this paper, we investigate a Cucker-Smale flocking model with varying time delay. We establish exponential asymptotic flocking without requiring smallness assumptions on the time delay size and the monotonicity of the influence function.

Field serological investigation for peste des petits ruminants, foot-and-mouth disease, and bluetongue diseases in illegally introduced animals in Egypt [PDF]

open access: yesVeterinary World, 2020
Aim: In this study, laboratory scoping on the viruses that cause peste des petits ruminants (PPR), bluetongue (BT), and foot-and-mouth disease (FMD) was performed to evaluate the current status of animals illegally introduced into Egypt.

Parameter estimation accuracies of Galactic binaries with eLISA [PDF]

open access: yesAstroparticle Physics, 2018, 2019
We study parameter estimation accuracy of nearly monochromatic sources of gravitational waves with the future eLISA-like detectors. eLISA will be capable of observing millions of such signals generated by orbiting pairs of compact binaries consisting of white dwarf, neutron star or black hole and to resolve and estimate parameters of several thousands ...

Application of the Biolog® Identification System for Aflatoxin-Producing Fungi Associated with Maize (Zea mays L.) Contamination in Romania

open access: yesBulletin of University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca: Agriculture, 2020
Cereals are very susceptible to fungal attacks. Fungi have a unique biochemical pathway to assimilate a vast array of available substrates and produce toxic secondary metabolites, such as mycotoxins, which represent a clear public health concern. In this
