Transmission of an optical wave through a multilayer structure with dispersive chiral layers

open access: yesФизика волновых процессов и радиотехнические системы
Background. The using of mirror asymmetric chemical compounds for doping quartz makes it possible to metamaterial creation that has the chirality property. In such a compositional structure, unusual effects may arise when interacting with an optical wave.

CSF Cytokine Network Organization Predicts Progression Independent of Relapse and MRI Activity in Multiple Sclerosis

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Progression independent of relapse activity is a major determinant of long‐term disability in multiple sclerosis, but its immunopathologic basis remains incompletely understood. We investigated whether relapse‐independent progression in radiologically stable relapsing–remitting multiple sclerosis is associated with distinct ...

Sensitivity analysis of the transmission coefficient (β0) for the transmission model.

open access: yes, 2023
We varied the transmission coefficient (β0) to determine sensitivity of case distribution. We ran the model with β0 = 1,2, and 4. The transmission coefficient should be approximated by R and β0 = 1 and β0 = 4 results in lower and higher transmission and ...

Observer‐Based Adaptive Event‐Triggered Tracking Control for Fuzzy TS Systems With Premise Mismatch

open access: yesInternational Journal of Adaptive Control and Signal Processing, EarlyView.
This paper presents an adaptive logistic event‐triggered observer‐based tracking controller for Takagi‐Sugeno fuzzy systems under constrained inputs and network delays. Leveraging a hybrid LMI and Secretary Bird Optimization approach, this strategy significantly minimizes communication overhead and computational burden while ensuring optimal reference ...

β‐Catenin/c‐Myc Axis Modulates Autophagy Response to Different Ammonia Concentrations

open access: yesAdvanced Biology, Volume 9, Issue 3, March 2025.
Ammonia, detoxified by the liver into urea and glutamine, impacts autophagy differently at varying levels. Low ammonia activates autophagy via c‐Myc and β‐catenin, while high levels suppress it. Using Huh7 cells and Spf‐ash mice, c‐Myc's role in cytoprotective autophagy is revealed, offering insights into hyperammonemia and potential therapeutic ...

Non-stationary thermal mode of a room at integrated regulation of split systems

open access: yesMagazine of Civil Engineering
Due to the non-linearity of the propagation of temperature waves in massive fences, one of the most difficult control objects is an air-conditioned room equipped with automated microclimate systems, especially if complex algorithms are used for ...

Monetary transmission in three central European economies: evidence from time-varying coefficient vector autoregressions. Bruegel Working Paper 2012/08, May 2012 [PDF]

open access: yes, 2012
We study the transmission of monetary policy to macroeconomic variables with structural time-varying coefficient vector autoregressions in the Czech Republic, Hungary and Poland, in comparison with that in the euro area.

Knee joint diathermy using microwave technology

open access: yesAl-Qadisiyah Journal for Engineering Science
: Microwave diathermy (MD) improves knee osteoarthritis pain and function. However, non- adherence to this therapy remains a major concern. The equipment is expensive and requires substantial deployment; thus, it's only available in professional ...
