Performance Comparison of Heterogeneous EESAA in Two and Three Dimensional Wireless Sensor Networks [PDF]

, 2016
Wireless Sensor Network is the network of limited power, computational and storage sensing devices called sensors. These sensors sense and send out data to other sensors present in the network. A considerable amount of energy is dissipated in these tasks.

Recent Advances in Laser‐Induced Graphene‐Based Gas Sensors: From Sensing Mechanisms to Biomedical Applications

Advanced Science, EarlyView.
Laser‐induced graphene (LIG) provides a scalable, laser‐direct‐written route to porous graphene architecture with tunable chemistry and defect density. Through heterojunction engineering, catalytic functionalization, and intrinsic self‐heating, LIG achieves highly sensitive and selective detection of NOX, NH3, H2, and humidity, supporting next ...

BNE-DETR: Nighttime Pedestrian Detection with Visible Light Sensors via Feature Enhancement and Multi-Scale Fusion

Sensors
Pedestrian detection faces significant performance degradation challenges in nighttime visible light environments due to degraded target features, background noise interference, and the coexistence of multi-scale targets. To address this issue, this paper proposes a BNE-DETR model based on an improved RT-DETR.

Remote Magnetomechanical Neuromodulation Uncovers Therapeutic Mechanisms for Alleviating Parkinsonian Symptoms in Freely Moving Mice

Advanced Science, EarlyView.
Magnetomechanical neuromodulation using magnetic nanodiscs enables remote activation of neurons. In a hemiparkinsonian mouse model, alternating magnetic fields actuate the nanodiscs to generate torque that opens mechanosensitive ion channels within the subthalamic nucleus, thereby modulating basal ganglia motor circuitry.

Retina‐Inspired Bi‐Based Terahertz Photonic Neuromorphic Devices

Advanced Science, EarlyView.
Combined with effective band alignment and substrate engineering, bismuth materials are introduced to form terahertz photonic bio‐inspired devices with picosecond short‐term plasticity to enable multi‐scene visual perception. Thus obtained hardware through the terahertz optical neural network (THz‐ONN) demonstrates high recognition accuracy, providing ...

Self-Powered Infrared 2D Nb8PtSe20 Sensors for Nighttime UAV Perception

Abstract Nighttime unmanned aerial vehicle (UAV) vision requires compact detectors that combine broadband photodetection with low-latency processing, yet visible-light sensors fail in darkness and existing long-wave infrared (LWIR) detectors typically require cryogenic cooling and off-chip computation. No self-powered

Single‐Step Electrochemical Aptasensor for Melatonin Detection in Unprocessed Plasma

Advanced Science, EarlyView.
Melatonin is a well‐known biomarker with significant potential for clinical use in diagnosing circadian rhythm sleep disorders (CRSDs) and monitoring patients with documented circadian clock disruption. An electrochemical aptamer‐based biosensor (E‐aptasensor), employing an optimized population of melatonin aptamers, has been proposed as a solution for

Open‐Shell Conjugated Polymers Enable Photothermoelectric Conversion and Detection of Short‐Wave Infrared Light

Advanced Science, EarlyView.
Efficient conversion and detection of short‐wave infrared (SWIR) photons are becoming increasingly important for emerging photonic and energy technologies. Here, we report an organic photothermoelectric device based on an open‐shell conjugated polymer that enables SWIR energy conversion and photon detection via the photothermoelectric effect.

α‐Synuclein Forms Distinct Micelle‐Like Assemblies at Low Ionic Strengths

Advanced Science, EarlyView.
At high ionic strength, α‐synuclein forms diverse assemblies, including oligomers, fibrils, and condensates. Here, we show that at low ionic strength, α‐synuclein adopts a distinct, low‐abundance assembly state. These assemblies maintain a constant size above a critical concentration and do not coalesce, suggesting a micelle‐like organization ...
