We investigate maximal ideals of pseudo-BCK-algebras and give some characterizations of them.

In this paper, the authors establish the sharp maximal estimates for the multilinear iterated commutators generated by [Formula: see text] functions and multilinear singular integral operators with generalized kernels. As applications, the boundedness of this kind of multilinear iterated commutators on the product of weighted Lebesgue spaces and the product of variable exponent Lebesgue spaces ...

The maximal complexifications adapted to the Levi Civita connection for a distinguished one-parameter family of left-invariant metrics on a real, non-compact, semisimple Lie group G are determined. For G = SL2(R) their realization as invariant Riemann domains over G = SL2(C) is carried out and their complex-geometric properties are investigated. One obtains new non-univalent, non-Stein examples.

The modeling of anticipatory coarticulation has been the subject of longstanding debates for more than 40 yr. Empirical investigations in the articulatory domain have converged toward two extreme modeling approaches: a maximal anticipation behavior (Look-ahead model) or a fixed pattern (Time-locked model). However, empirical support for any of these models has been hardly conclusive, both withi...

Phenotypic plasticity is a key factor for the success of organisms in heterogeneous environments. Although many forms of phenotypic plasticity can be induced and retracted repeatedly, few extant models have analyzed conditions for the evolution of reversible plasticity. We present a general model of reversible plasticity to examine how plastic shifts in the mode and breadth of environmental tol...

Despite the increasing number of older adults’ growing need for health information, little is known about their motivation to seek online information. This exploratory qualitative study was conducted examine why adults required information through sources. In this content analysis, we purposefully approached 19 with age in range between 60–75 (63.78 ± 3.8 years) Tabriz, Iran. Data were collecte...

Background: Emerging COVID-19 pandemic has posed numerous ethical challenges to frontline healthcare professionals. Objectives: This study aimed explain the experienced by physicians and nurses in caring for patients during early phases of pandemic. Methods: qualitative was conducted using content analysis approach. Twenty-two semi-structured in-depth interviews were with 18 working medical cen...

Introducción: La pandemia por COVID-19 ha generado transformaciones importantes en la sociedad. Para educación superior, especialmente las instituciones y centros de atención médica con programas formación médicos especialistas, medidas confinamiento generaron retos para continuidad los procesos enseñanza-aprendizaje, a partir del diseño e implementación nuevas estrategias preservar médica.&#x0...
