INFLUENCE OF THE stimulated Brillouin scattering PREAMPLIFIER NOISE ON RECEIVING THE TRANSFORMED SPECTRUM SIGNALS

Доклады Белорусского государственного университета информатики и радиоэлектроники, 2019
An analysis of the influence of preamplifier noise with effect of stimulated Brillouin scattering (SBS) in the SNR on receiving the transformed spectrum signals was presented in this paper.

Monolithic integration of SiC diode detectors into scanning X‐ray microscopy optical elements for in situ beam diagnostics

Journal of Synchrotron Radiation, EarlyView.
Silicon carbide detectors are monolithically integrated into order‐sorting apertures and center stops for in situ soft X‐ray beam diagnostics in STXM. Functionalized components enable simultaneous monitoring of incident beam intensity and the transverse position at sample‐relevant locations without degrading optical performance.Reliable monitoring of ...

Novel murine closed‐loop auditory stimulation paradigm elicits macrostructural sleep benefits in neurodegeneration

Journal of Sleep Research, Volume 34, Issue 2, April 2025.
Summary Boosting slow‐wave activity (SWA) by modulating slow waves through closed‐loop auditory stimulation (CLAS) might provide a powerful non‐pharmacological tool to investigate the link between sleep and neurodegeneration. Here, we established mouse CLAS (mCLAS)‐mediated SWA enhancement and explored its effects on sleep deficits in neurodegeneration,

Is resting muscle sympathetic nerve activity related to peripheral or cerebrovascular haemodynamics at high altitude? A retrospective analysis

Experimental Physiology, EarlyView.
Abstract High‐altitude hypoxia elicits several profound physiological responses, including substantial increases in muscle sympathetic nerve activity (MSNA); however, the association of this heightened MSNA with cardiovascular and cerebrovascular haemodynamics remains unclear in lowlanders and indigenous highlander populations.

Tonotopically distinct OFF responses arise in the mouse auditory midbrain following sideband suppression

The Journal of Physiology, EarlyView.
Abstract figure legend Sounds of different frequencies elicit spatially distinct patterns of neural activity within the inferior colliculus aligned to the tonotopic organization of afferent projections. Sound‐evoked neural responses can be visualized in awake mice that express fluorescent Ca2+ sensors.

Noise‐induced reduction and early recovery of superior paraolivary nucleus sound‐offset responses

The Journal of Physiology, EarlyView.
Abstract figure legend Acoustic over‐exposure transiently disrupts auditory temporal processing in mouse superior paraolivary nucleus neurons. In control conditions, neurons exhibit robust sound‐offset (OFF) responses, which are abolished immediately following noise trauma, indicating impaired temporal encoding.

Breathing irregularities and postnatal hypoxaemia in an experimental model of essential hypertension

The Journal of Physiology, EarlyView.
Abstract figure legend Neonatal spontaneously hypertensive rats (SHRs) exhibit inherent respiratory dysfunction in early life, including oscillatory breathing patterns and apnoeic events that cause oxygen desaturation and brain hypoxia, in addition to an impaired hypoxic ventilatory response.

Marked C‐tactile afferent suppression by a plastic film does not proportionately diminish pleasantness of gentle brushing

The Journal of Physiology, EarlyView.
Abstract figure legend Human skin contains several classes of mechanoreceptive afferents that encode mechanical stimulation. For example, C‑tactile (CT) afferents are suggested to signal the pleasant aspects of gentle touch and are activated effectively by slow brushing of hairy skin.

Design of an 8‐Channel Transmit 32‐Channel Receive 11.7T Head Coil and Evaluation of SNR Gains

Magnetic Resonance in Medicine, Volume 96, Issue 4, Page 2004-2018, October 2026.
ABSTRACT Purpose To design and develop an 8‐channel transmit 32‐channel receive 11.7T head coil for the strongest human MRI scanner to date, demonstrate safety, and evaluate signal‐to‐noise ratio (SNR) gains compared to 7T, the most used ultra‐high‐field (UHF) platform.
