Switch sensors and methods of use
Patent published on the 2026-10-15 in US under Ref US20260318905 by BOARD OF REGENTS THE UNIV OF TEXAS SYSTEM [US] (Ye Jing Yong [us], Trabucco Luis [us], Shaw Jonathan [us])
Abstract: Current fluorescent biosensors rely on fluorescent spectrum shifts, limiting the detection technique compatible with the technology. These limitations hinder the ability to utilize fluorescent biosensing technologies in vivo. Switch sensors are biosensors that allow for the sensitive detection of target analytes through a diverse set of detection techniques. Switch sensor monomers are comprised of a platform segment, a linker, and a fluorescent dye monomer. The aptamer or polypeptide-based platf[...]
Our summary: Switch sensors enhance biosensing by enabling diverse detection methods beyond fluorescence. They consist of a platform segment, linker, and fluorescent dye monomer. The binding of target analytes alters the absorption spectrum, expanding detection capabilities.

Non-terrestrial network (ntn) handover and doppler compensation
Patent published on the 2026-10-15 in WO under Ref WO2026213728 by ZHANG XUQIANG [CN] (Zhang Xuqiang [cn], Zhang Yushu [cn])
Abstract: This disclosure provides systems, methods, and apparatuses for handover or mobility (handover/mobility) prediction operation in a non-terrestrial network (NTN). A satellite or a UE can predict that the UE will need to perform a handover/mobility procedure due to the movement of the satellite and the UE being near an edge of a coverage area of an NTN cell or beam (124A) provided by the satellite. In some aspects, a prediction is based on measurements of reference signals, such as angle of arrival[...]
Our summary: This disclosure outlines systems and methods for predicting handover in non-terrestrial networks. It describes how a satellite or user equipment can anticipate mobility needs based on coverage area boundaries. Additionally, it addresses Doppler compensation to adjust transmission frequencies for satellite movement.

system modeling and parameter dependence analysis
Published on 2026-10-06 by Chuan Qu and Jian Zhang @IOP SCIENCE
Abstract: Continuously tunable Rydberg atomic receivers (CT-RARs) based on the AC Stark effect overcome the discrete-frequency limitations of resonant RARs, enabling wideband continuous spectrum coverage. However, existing studies lack a dynamic system model tailored to the CT-RAR, and nonlinear distortion characteristics remain poorly understood, which hinders further optimization of receiver sensitivity. This paper presents theoretical system modeling and performance analysis of the CT-RAR. A small-sign[...]
Our summary: This paper presents a dynamic system model for continuously tunable Rydberg atomic receivers (CT-RARs) using time-dependent perturbation theory. It analyzes the nonlinear distortion characteristics and derives expressions for the dynamic frequency response.

Memory and hysteresis in frictional granular matter
Published on 2026-10-06 by M M Bandi and R E Ecke @IOP SCIENCE
Abstract: We experimentally investigate hysteresis, aging, and memory formation in a quasi-two-dimensional assembly of bi-disperse frictional granular disks subjected to uniaxial compression–decompression cycles. Using controlled interparticle friction, sub-micron boundary displacements, and spatially homogeneous acoustic excitation, we measure global stress and grain-scale contact forces—via photoelastic imaging—to directly consider how macroscopic hysteretic response relates to microscopic frictio[...]
Our summary: This study investigates hysteresis, aging, and memory in bi-disperse frictional granular disks under compression-decompression cycles. It identifies key features of Preisach hysteresis, including sub-loop nesting and return-point memory, while discussing deviations from the model. The research also explores the relationship between granular mechanics and classical disordered hysteretic systems through quantitative measurements.
