Comparison of swarm intelligence algorithms for optimized band selection of hyperspectral remote sensing image

open access: yesOpen Geosciences, 2020
Swarm intelligence algorithms have been widely used in the dimensional reduction of hyperspectral remote sensing imagery. The ant colony algorithm (ACA), the clone selection algorithm (CSA), particle swarm optimization (PSO), and the genetic algorithm ...

Foliation-Based Approach to Quantum Gravity and Applications to Astrophysics

open access: yesUniverse, 2019
The recently proposed holography-inspired approach to quantum gravity is reviewed and expanded. The approach is based on the foliation of the background spacetime and reduction of the offshell states to the physical states.

Expansion of a quantum gas in a shell trap

open access: yesNew Journal of Physics, 2022
We report the observation of the controlled expansion of a two-dimensional (2D) quantum gas confined onto a curved shell-shaped surface. We start from the ellipsoidal geometry of a dressed quadrupole trap and introduce a novel gravity compensation ...

Search efficiency in the Adam–Delbrück reduction-of-dimensionality scenario versus direct diffusive search

open access: yesNew Journal of Physics, 2022
The time instant—the first-passage time (FPT)—when a diffusive particle (e.g., a ligand such as oxygen or a signalling protein) for the first time reaches an immobile target located on the surface of a bounded three-dimensional domain (e.g., a hemoglobin

Therapeutic Apheresis for Intravenous Methylprednisolone‐Refractory Neuromyelitis Optica Spectrum Disorder: Clinical and Radiological Outcomes in a Single‐Center Case Series

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Neuromyelitis optica spectrum disorder (NMOSD) is a relapsing autoimmune disease of the central nervous system. High‐dose intravenous methylprednisolone (IVMP) is the standard first‐line therapy for acute attacks, although some patients remain refractory.

Numerické hodnocení reologickéh o experimentu [PDF]

open access: yesACC Journal, 2012
Uvažujeme viskoelastické, prostě podepřené, rotačně symetrické těleso pevně spojené s podkla-dem. Těleso je zatěžováno plochou lisovací čelisti, která se pohybuje ve směru osy z konstantní rychlostí v.

Torsion in cohomology and dimensional reduction

open access: yesJournal of High Energy Physics, 2023
Conventional wisdom dictates that ℤ N factors in the integral cohomology group H p (X n , ℤ) of a compact manifold X n cannot be computed via smooth p-forms.

Learning Picture Languages Using Dimensional Reduction

open access: yesInteligencia Artificial, 2023
One-dimensional (string) formal languages and their learning have been studied in considerable depth. However, the knowledge of their two-dimensional (picture) counterpart, which retains similar importance, is lacking.

Organoids in pediatric cancer research

open access: yesFEBS Letters, EarlyView.
Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.
