Hot-carrier and optical-phonon ultrafast dynamics in the topological insulator Bi[sub]2Te[sub]3 upon iron deposition on its surface
M. Weis, K. Balin, B. Wilk, T. Sobol, A. Ciavardini, G. Vaudel, V. Juvé, B. Arnaud, Barbara Ressel, Matija Stupar, Giovanni De Ninno

Oznake: time resolved spectroscopies;topological insulators;interfaces;
This paper presents a complete study of electronic structures and photoexcited carrier dynamics in topological insulators capped with iron and iron oxide. We combine static and time-resolved angle-resolved photoemission spectroscopies (ARPES, TR-ARPES) with time-resolved optical methods (transient o ...

Experimental attempts of using modulated and unmodulated waves in low-frequency acoustic wave flame extinguishing technology
Trung Thanh Nguyen, Grzegorz Wilk-Jakubowski, Valentyna Loboichenko
Izvirni znanstveni članek
Oznake: acoustic flame extinguishing;firefighting systems;deep neural networks;fire extinguisher;flame suppression;
In practice, some undesired signals perceived as noise (because of the sound sensation) can effectively extinguish flames. This article provides information on the applicability of acoustic waves (a case of using sine waves and sine waves amplitude modulated by a square waveform) in low-frequency ac ...

Oznake: šport;dihanje;nadmorska višina;hipoksija;hipoksemija;AMS;preprečevanje;sport;respiration;altitude;hypoxia;hypoxemia;prevention;
This study aimed to examine the physiological mechanisms associated with Voluntary Isocapnic Hyperpnoea (VIH) in severe hypoxia and evaluated whether such respiratory modulation may attenuate hypoxemia and Acute Mountain Sickness (AMS). Eighteen healthy participants (8 females) completed two 2-hour ...

Novel wearable near-infrared spectroscopy devices allow for a better understanding of muscle oxygenation kinetics during exercise. A muscle oxygen saturation (SmO$_2$) plateau is often applied in the scientific literature, but clear criteria for its definition remain unestablished to date. The aim o ...

Critical power and critical oxygenation

Izvirni znanstveni članek
Oznake: sport;NIRS;altitude;hypoxia;critical power;testing;muscle oxygenation;cycling;
We sought to investigate if critical oxygenation (COx) is a robust marker of exercise intensity, and if it remains stable in normoxia and hypoxia with simultaneous changes in critical power (CP) and heart rate (HR). Thirty-three highly trained endurance athletes (11 females) underwent two 3-min CP c ...
