Transistor‐Level Activation Functions via Two‐Gate Designs: From Analog Sigmoid and Gaussian Control to Real‐Time Hardware Demonstrations

open access: yesAdvanced Materials, EarlyView.
Screen gate‐based transistors are presented, enabling tunable analog sigmoid and Gaussian activations. The SA‐transistor improves MRI classification accuracy, while the GA‐transistor supports precise Gaussian kernel tuning for forecasting. Both functions are implemented in a single device, offering compact, energy‐efficient analog AI processing ...

Spatially Programmable Electroadhesive Enables In Situ Site‐Selective Functional Coupling

open access: yesAdvanced Materials, EarlyView.
A light‐activated, in situ spatially programmable bioadhesive (STICH) enables microscale, site‐selective integration of bioelectronic devices with wet tissue. It achieves robust mechanical bonding and low‐impedance electrical coupling, enabling reconfigurable neuromodulation and directional electromechanical sensing in vivo and ex vivo.

Casting marks on Scythian arrowheads as chronological indicators: the slant line mark

open access: yesМатериалы по археологии и истории античного и средневекового Причерноморья, 2021
From the middle of the 5th century BCE casting marks appear оn Scythian arrowheads. One type of mark that became widespread is the mark in the form of an oblique line slanted to the left (a slash).

Chemical chronology of the Southern Coalsack

open access: yes, 2007
We demonstrate how the observed H2O ice column densities toward three dense globules in the Southern Coalsack could be used to constrain the ages of these sources. We derive ages of ~10^5 yr, in agreement with dynamical studies of these objects.

Comparative Advances in Sulfide and Halide Electrolytes for Commercialization of All‐Solid‐State Lithium Batteries

open access: yesAdvanced Materials, EarlyView.
This review compares sulfide‐ and halide‐based solid electrolytes for all‐solid‐state lithium batteries (ASSBs), highlighting their ionic conductivity, chemical stability, manufacturability, and compatibility with lithium metal. Sulfides offer higher conductivity, while halides provide enhanced stability and scalability.

Chronology of a Medieval complex from the Papskoye settlement (forest-steppe of Western Siberia)

open access: yesВестник археологии, антропологии и этнографии, 2020
A large number of imported items found in the occupation layers of archaeological sites in the Trans-Urals and Western Siberia suggest that, in the Middle Ages, these regions were on the periphery of trade routes and were involved in global historical ...

Chronology protection in stationary three-dimensional spacetimes

open access: yes, 2011
We study chronology protection in stationary, rotationally symmetric spacetimes in 2+1 dimensional gravity, focusing especially on the case of negative cosmological constant.
