Rapid Spectral Evolution of SGR 1935+2154 during Its 2022 Outburst
The Astrophysical JournalDuring the 2022 outburst of SGR 1935+2154, a fast radio burst (FRB)-like event (FRB 20221014A) and X-ray activities occurred between two spin-up glitches, suggesting these glitches may connect to multiwavelength phenomenology.

First Mode Schumann Resonance Frequency Variation During a Solar Proton Event
Terrestrial, Atmospheric and Oceanic Sciences, 2016 A severe X-ray flare occurred on 06 - 07 March 2012 followed by a solar proton event (SPE). During this event we studied the variation in frequency of the first Schumann resonance (SR) spectra mode from the recorded data over Kolkata (22.56°N, 88.5°E ...

Effect of Viewing Angle in Gamma-Ray Burst Properties
The Astrophysical JournalThe empirical classification of gamma-ray bursts (GRBs) is based on their distribution in the plane of burst duration and spectral hardness. Two distinct distributions, long-soft and short-hard bursts, are observed in this plane, forming the basis for ...

Surface Modes on Bursting Neutron Stars and X‐Ray Burst Oscillations
The Astrophysical Journal, 2005 Accreting neutron stars (NSs) often show coherent modulations during type I X-ray bursts, called burst oscillations. We consider whether a nonradial mode can serve as an explanation for burst oscillations from those NSs which are not magnetic. We find that a surface wave in the shallow burning layer transitions into a crustal interface wave as the ...

Prior Expectations Bias Confidence Judgments Through Parietal Alpha‐Band Modulation
Advanced Science, EarlyView.ABSTRACT Humans possess the metacognitive ability to estimate the likely accuracy of their own decisions through confidence judgments. Yet, whether prior information shapes confidence and the neural mechanisms mediating such influence, remain to be determined.

Spatial Engineering of Gas Diffusion Layers Overcomes Mass Transport Limitations in Fuel Cells
Advanced Science, EarlyView.ABSTRACT Mass transport limitations at high current densities hinder polymer electrolyte fuel cell (PEFC) performance due to inefficient water management and reactant distribution. Gas diffusion layer (GDL) perforation offers a potential solution as an alternative to complex flow‐field modifications.

On the nature of photospheric oscillations in strong X-ray bursts
The Astrophysical Journal, 1994 A possible sound origin for the photospheric oscillations in the X--ray bursting sources 1608-522 and 2127+119 is suggested. It is shown that standing sound waves in an expanding spherical envelope can have periods very close to the observed ones. The quite large ratio, $\sim$ 10, of the periods in the two sources is explained in terms of different ...
