LanthanideDoping and Dual-Site Switching on AmorphousHigh-Entropy Metallene Oxides Boost Acidic Water Oxidation
High-entropy oxides (HEOs) are promising electrocatalysts for breaking the Sabatier principle and maximizing their oxygen evolution reaction (OER) efficiency. Herein, the effect of lanthanide doping on RuIr-based HEOs is investigated through theoretical and experimental studies. The optimized amorphous RuIrMnCoGd high-entropy metallene oxides (a-Gd_HEMOs) with moderate intermediate affinity exhibit a small overpotential of 211 mV and an ultralong stability of 700 h at 10 mA cm(-2) in acidic medi

Flexible and Self-Powered Wearable Sensors for Tremor Monitoring in Parkinson'S Disease: Recent Advances in Materials and Device Architectures
Parkinson’s disease (PD) is a progressive neurodegenerative disorder where tremor remains one of the most prominent anddisabling motor symptoms. Traditional clinical rating scales for disease severity rely on clinician observation and patient self-report, often failing to capture the dynamic and continuous nature of tremors in daily life. This drives the development of objectivemonitoring technologies, such as wearable sensors, for more accurate evaluation of PD severity. However, many existing

Ultrafast Multilevel Switching and Synaptic Behavior in a Planar Quantum Topological Memristor
The rapid increase in data driven by analytics and Internet of Things demands innovation in both device architecture and materials to meet the growing need for fast and efficient computing. Here we report an ultrafast planar quantum topological memristor (PQTM), comprised of bismuth-telluride (Bi2Te3) thin film transferred onto pre-patterned electrodes. Owing to the planar architecture, the device connects both electrodes to the surface states of Bi2Te3, offering a platform to directly benefit f

Applications of flexible and stretchable three-dimensional structures for soft electronics
The development of devices that can be mechanically deformed in geometrical layouts, such as flexible/stretchable devices, is important for various applications. Conventional flexible/stretchable devices have been demonstrated using two-dimensional (2D) geometry, resulting in dimensional constraints on device operations and functionality limitations. Accordingly, expanding the dimensions in which such devices can operate and acquiring unique functionality that is difficult to implement in 2D pla

Precise Synchronization Between LiDAR and Multiple Cameras for Autonomous Driving: An Adaptive Approach
LiDAR and camera are crucial perception sensors that provide complementary information for object detection in autonomous driving vehicles. However, the fusion of sensor data to achieve efficient object detection requires accurate calibration and precise time synchronization between the sensors. While calibration ensures the geometric relationship between the sensors, and time synchronization ensures that data from both sensors corresponds to the same moment in the real world. Even though variou

Edge-Server Workload Characterization in Vehicular Computation Offloading: Semantics and Empirical Analysis
Edge server-assisted computation offloading enables vehicles to leverage server compute resources to deliver connected services, overcoming the limitations of onboard resources. Understanding the compute workloads of edge servers is crucial for effective resource management and scheduling, yet this task is challenging due to the complex interplay of factors such as vehicle mobility and computation offloading patterns. To address this, we propose an empirical analysis framework that systematicall

Recent Advances in Ultra-High-Speed Wireline Receivers with ADC-DSP-Based Equalizers
High-speed wireline data transceivers (TRX) with analog-to-digital converter (ADC) followed by digital signal processor (DSP) on the receiver (RX) equalizer became popular for applications requiring >100 Gb/s per-lane data rate over long-reach (LR) channels, especially for datacenter applications. With the digital-to-analog converter (DAC)-based transmitter (TX) including DSP-based TX signal processing, the overall structure of DAC/ADC-DSP-based wireline TRXs became similar to modulator/demodula
