On power homogeneous spaces

open access: yesTopology and its Applications, 2002
AbstractThe notion of a Moscow space [A.V. Arhangel'skii, Comment. Math. Univ. Carolinae 24 (1983) 105–120] and a new notion of a weakly Klebanov space, introduced below, are applied to study topological properties of spaces X such that some power of X is homogeneous. Under this approach, a crucial role is played by a theorem of Y. Yajima [J. Math. Soc.

Factors for Rituximab Refractoriness in AQP4‐IgG+ NMOSD: A Cohort Study

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Neuromyelitis optica spectrum disorder (NMOSD) is a severe autoimmune condition of the central nervous system (CNS), often associated with aquaporin‐4 antibodies (AQP4‐IgG). Rituximab, a CD20+ B‐cell depleting monoclonal antibody, is widely used as first‐line therapy.

Homogeneous Subspaces of Products of Extremally Disconnected Spaces

open access: yes, 2018
Homogeneous countably compact spaces $X$ and $Y$ whose product $X\times Y$ is not pseudocompact are constructed. It is proved that all compact subsets of homogeneous subspaces of the third power of an extremally disconnected space are finite.

More on the cardinality of a topological space

open access: yesApplied General Topology, 2018
In this paper we continue to investigate the impact that various separation axioms and covering properties have onto the cardinality of topological spaces. Many authors have been working in that field.

Fecal Microbiota Transplantation Modulates Th17/Treg Balance via JAK/STAT Pathway in ARDS Rats

open access: yesAdvanced Biology, EarlyView.
Fecal microbiota transplantation (FMT) alleviates lung and intestinal injury in lipopolysaccharide (LPS)‐induced acute respiratory distress syndrome (ARDS) in rats. This study demonstrates that FMT restores the balance between Th17 and Treg cells, inhibits the JAK/STAT pathway, and modulates cytokine levels, reducing inflammation and lung damage. These

Characterization of a homogeneous Orlicz space

open access: yesElectronic Journal of Differential Equations, 2017
In this article we define and characterize the homogeneous Orlicz space $\mathscr{D}^{1,\Phi}_{\rm o}(\mathbb{R}^{N})$ where $\Phi:\mathbb{R}\to [0,+\infty)$ is the N-function generated by an odd, increasing and not-necessarily differentiable ...

Preferred Parameterisations on Homogeneous Curves [PDF]

open access: yes, 2003
We show how to specify preferred parameterisations on a homogeneous curve in an arbitrary homogeneous space. We apply these results to limit the natural parameters on distinguished curves in parabolic geometries.Comment: 10 ...

Numerical Studies of Influencing Factors on the Homogeneity of the Powder Mixture during the Powder Spreading Process of Powder Bed Fusion–Laser Beam/Metal

open access: yesAdvanced Engineering Materials, EarlyView.
AISI 304L stainless steel powder is mixed with silicon nitride (Si3N4) powder and processed by PBF‐LB/M, allowing partial retention of Si3N4. The numerical approach effectively predicts the Si3N4 powder homogeneity and N content distribution on the powder bed. Recent studies have focused on the alloying of nitrogen (N) in high‐alloy stainless steels by
