Mass, charge, and distance to Reissner-Nordström black hole in terms of directly measurable quantities [PDF]

Eur. Phys. J. C 84 (2024) 525
In this paper, we employ a general relativistic formalism and develop new theoretical tools that allow us to analytically express the mass and electric charge of the Reissner-Nordstr\"{o}m black hole as well as its distance to a distant observer in terms of few directly observable quantities, such as the total frequency shift, aperture angle of the ...

Thermal Processing Creates Water‐Stable PEDOT:PSS Films for Bioelectronics

Advanced Materials, Volume 37, Issue 13, April 2, 2025.
Instead of using chemical cross–linkers, it is shown that PEDOT:PSS thin films for bioelectronics become water‐stable after a simple heat treatment. The heat treatment is compatible with a range of rigid and elastomeric substrates and films are stable in vivo for >20 days.

Investigation for the Temperature Dependence of 2D Electron Gas Behaviors in GaN‐based Multichannel Heterostructures Systems

Advanced Materials Interfaces, EarlyView.
The GaN‐based multichannel heterostructures with larger band conduction difference own better temperature stability. And lattice‐matched heterostructures can improve the temperature stability of the 2D electron gas in the bottom channel. Abstract In this study, 2 electron gas(2DEG) behaviors in Al0.28Ga0.72N/GaN multichannel heterostructures with doped

A Simple, Fast and Fully Automated Approach for Midline Shift Measurement on Brain Computed Tomography [PDF]

arXiv, 2017
Brain CT has become a standard imaging tool for emergent evaluation of brain condition, and measurement of midline shift (MLS) is one of the most important features to address for brain CT assessment. We present a simple method to estimate MLS and propose a new alternative parameter to MLS: the ratio of MLS over the maximal width of intracranial region

Ultra‐Flexible µ‐ECoG Arrays Based on PEDOT:PSS Micropillars

Advanced Materials Interfaces, EarlyView.
This work demonstrates an efficient procedure for fabricating ultra‐flexible neural interfaces endowed with micropatterned microelectrodes to increase surface area and characterized by extremely low impedance values to enable high‐quality recordings. The home‐built device has been shown to record somatosensory evoked potentials in vivo with exceptional
