Finiteness Principles for Smooth Selection [PDF]

open access: yesGeometric and Functional Analysis, 2016
In this paper we prove finiteness principles for $C^{m}\left( \mathbb{R}^{n}, \mathbb{R}^{D}\right) $-selection, and for $C^{m-1,1}\left( \mathbb{R}^{n}, \mathbb{R}^{D}\right) $-selection, in particular providing a proof for a conjecture of Brudyni-Shvartsman (1994) on Lipschitz selections for the case when the domain is $X = \mathbb{R}^n$.

Selection of soil for transition layers in earth dams on the example of the Świnna Poręba Dam [PDF]

open access: yesActa Scientiarum Polonorum. Architectura, 2020
The article presents considerations on the principles of soil selection for transition layers in earth dams, both of which also act as reverse filters. It focuses on the identification of phenomena related to filtration, in particular internal erosion ...

Selection principles and covering properties in bitopological spaces

open access: yesApplied General Topology, 2020
Our main focus in this paper is to introduce and study various selection principles in bitopological spaces. In particular, Menger type, and Hurewicz type covering properties like: Almost p-Menger, star p-Menger, strongly star p-Menger, weakly p-Hurewicz,

Principles and correction of 5’-splice site selection

open access: yesRNA Biology, 2022
In Eukarya, immature mRNA transcripts (pre-mRNA) often contain coding sequences, or exons, interleaved by non-coding sequences, or introns. Introns are removed upon splicing, and further regulation of the retained exons leads to alternatively spliced ...

SELECTION OF AN APPROPRIATE PERSONAL PROTECTIVE EQUIPMENT USING THE ANALYTIC HIERARCHY PROCESS

open access: yesEskişehir Osmangazi Üniversitesi Mühendislik ve Mimarlık Fakültesi Dergisi, 2022
The main principles of safety risk reduction are elimination, substitution, and engineering controls. Hazardous conditions, safe work practices, and other forms of managerial controls should be provided for a safe work environment.

Principles of confounder selection [PDF]

open access: yesEuropean Journal of Epidemiology, 2019
AbstractSelecting an appropriate set of confounders for which to control is critical for reliable causal inference. Recent theoretical and methodological developments have helped clarify a number of principles of confounder selection. When complete knowledge of a causal diagram relating all covariates to each other is available, graphical rules can be ...

Relationships between some selection principles and star selection principles

open access: yesTopology and its Applications, 2022
Motivated by the definition of classical star selection principles, Cruz-Castillo, Ram rez-P ramo and Tenorio defined some selection principles and posed several questions about relationships between these notions and some of the classical star selection principles. The main goal of this paper is to answer the questions posed by these authors.

Weak covering properties and selection principles [PDF]

open access: yes, 2012
No convenient internal characterization of spaces that are productively Lindelof is known. Perhaps the best general result known is Alster's internal characterization, under the Continuum Hypothesis, of productively Lindelof spaces which have a basis of ...
