Enhanced Reaction Kinetics in Sodium‐Ion Batteries Achieved by 3D Heterostructure CoS2/CoS with Self‐Induced Internal Electric Field

Advanced Science, EarlyView.
A novel HC@CoS2/CoS/NC composite with optimized heterointerfaces is successfully synthesized as an ultrastable and fast‐charging anode material for SIBs. This composite features a 3D architecture, characterized by highly dispersed CoS2/CoS/NC nanoparticles embedded within honeycomb carbon nanosheets.

On the Validity of the Noise Model of Quantization for the Frequency-Domain Amplitude Estimation of Low-Level Sine Waves

Metrology and Measurement Systems, 2015
This paper deals with the amplitude estimation in the frequency domain of low-level sine waves, i.e. sine waves spanning a small number of quantization steps of an analog-to-digital converter.

Protected Chaos in a Topological Lattice

Advanced Science, EarlyView.
Topological and chaotic dynamics are often considered incompatible, with one expected to dominate or disrupt the other. This work reveals that topological localization can persist even under strong chaotic dynamics and, counter‐intuitively, protect chaotic behavior.

C1q+ Macrophage–Tumor Cell Interaction Promoted Tumorigenesis via GPR17/PI3K/AKT Pathway Induced DNA Hypermethylation in Nasopharyngeal Carcinoma

Advanced Science, EarlyView.
In the TME of NPC, C1q secreted by C1q+ TAMs interacted with GPR17 to activate PI3K/AKT signaling through strengthening GPR17 coupling PI3K and increasing calcium levels in tumor cells. The activated PI3K/AKT signaling further induces DNA hypermethylation to promote the malignancy and stemness of tumor cells.

Physical Reservoir Computing for Real‐Time Electrocardiogram Arrhythmia Detection Through Controlled Ion Dynamics in Electrochemical Random‐Access Memory

Advanced Electronic Materials, EarlyView.
This study presents an ECRAM‐based physical reservoir computing system for real‐time electrocardiogram arrhythmia detection. By optimizing electrolyte ionic conductivity and channel ionic diffusivity, it achieves including non‐linear dynamics, millisecond‐scale tunable retention, low‐power operation, and minimal variation.
