Quasinormal Fitting classes of finite groups

open access: yesЖурнал Белорусского государственного университета: Математика, информатика, 2019
Let P be the set of all primes, Zn a cyclic group of order n and X wr Zn the regular wreath product of the group X with Zn. A Fitting class F is said to be X-quasinormal (or quasinormal in a class of groups X ) if F ⊆ X, p is a prime, groups G ∈ F and G ...

Quasispecies on Class-Dependent Fitness Landscapes [PDF]

open access: yesBulletin of Mathematical Biology, 2016
We study Eigen's quasispecies model in the asymptotic regime where the length of the genotypes goes to infinity and the mutation probability goes to 0. We give several explicit formulas for the stationary solutions of the limiting system of differential equations.

Neutral temperature and atmospheric water vapour retrieval from spectral fitting of auroral and airglow emissions [PDF]

open access: yesGeoscientific Instrumentation, Methods and Data Systems, 2018
We have developed a spectral fitting method to retrieve upper atmospheric parameters at multiple altitudes simultaneously during times of aurora, allowing us to measure neutral temperatures and column densities of water vapour.

Il paesaggio del futuro. Temi di responsabilità

open access: yesRi-vista: Ricerche per la Progettazione del Paesaggio, 2015
Landscape is a process. Under a strictly functional profile, landscape is a translation and exchanging process between material, energy and information. Landscape is also an evolution and fitting process, being a dissipating and fitting system. Landscape

Combining Hybrid Approach Redefinition-Multiclass Imbalance (HAR-MI) and Hybrid Sampling in Handling Multi-Class Imbalance and Overlapping

open access: yesJOIV: International Journal on Informatics Visualization, 2021
The class imbalance problem in the multi-class dataset is more challenging to manage than the problem in the two classes and this problem is more complicated if accompanied by overlapping.

An IBBCEAS system for atmospheric measurements of glyoxal and methylglyoxal in the presence of high NO2 concentrations [PDF]

open access: yesAtmospheric Measurement Techniques, 2019
A system based on incoherent broadband cavity-enhanced absorption spectroscopy (IBBCEAS) has been developed for simultaneous measurement of nitrogen dioxide (NO2), glyoxal (GLY), and methylglyoxal (MGLY).

Assessment of rock fragmentation and strength properties using the Rosin-Rammler and Extended Swebrec Distribution functions parameters [PDF]

open access: yesInternational Journal of Mining and Geo-Engineering, 2022
This work assessed the curve fitting ability of Rosin-Rammler and Swebrec functions and the comparison of their fitting parameters with rock strength properties.

The concept of neutral zone and rehabilitation of severely resorbed alveolar ridges: A special case file

open access: yesJournal of International Clinical Dental Research Organization, 2020
Mandibular dentures often present greater difficulty in achieving retention, stability, and support than do maxillary dentures, primarily, due to a complex anatomy because of bone architecture and muscle attachments, and consequently, increased number of

Minimal Fitting Classes

open access: yesIrish Mathematical Society Bulletin, 1988
These two papers [see also the following item Zbl 0667.20016] are both about Fitting Class theory. A class \({\mathcal F}\) of finite groups is called a Fitting Class if it satisfies two properties, i) if \(G\in {\mathcal F}\) and H is a normal subgroup of G then \(H\in {\mathcal F}\) and ii) if G is a finite group and H and K are both normal subgroups
