Estimate of Passive Time Reversal Communication Performance in Shallow Water
Applied Sciences, 2017 Time reversal processes have been used to improve communication performance in the severe underwater communication environment characterized by significant multipath channels by reducing inter-symbol interference and increasing signal-to-noise ratio.

The Effects of Inter-Symbol Interference in Dynamic Element Matching DACs
IEEE Transactions on Circuits and Systems I: Regular Papers, 2017 Dynamic element matching (DEM) is often applied to multi-bit DACs to avoid nonlinear distortion that would otherwise result from inevitable mismatches among nominally identical circuit elements. Unfortunately, for such a DEM DAC to fully achieve this objective its constituent 1-bit DACs must be free of inter-symbol interference (ISI), i.e., the error ...

Life‐Like Ferrous Oxide Microspheres from Kombucha
Advanced Materials Interfaces, EarlyView.Kombucha bacterial cellulose, sodium alginate, and ferrous nitrate self‐assemble into membrane‐enclosed iron oxide microspheres. These microspheres bud daughter vesicles, sustain 24‐h electrochemical oscillations, and filter theta‐band signals.

Modeling and analysis of inter-symbol interference (ISI) jitter
IEICE Electronics Express, 2007 This paper presents a novel modeling and analysis of inter-symbol interference (ISI)jitter in serial data channels either between chips or on chip. The simulation results show that ISI jitter is dependent on pole location, settling time, and damping ratio of the data serial channel.

Advanced Optical Materials, EarlyView.A theory‐guided magnetoelectric metasurface design breaks the conventional optical transparency and electromagnetic performance trade‐offs. By preserving the electric and magnetic current paths required for efficient reflection through fine‐metal‐line structure, the developed transparent reflective metasurface achieves high optical transparency without

Multimodal Engagement Assessment in Children During Invented Story Paradigm With a Social Robot
Advanced Robotics Research, EarlyView.A multimodal framework is proposed to assess children's engagement during storytelling interactions with a social robot. Gaze, physiological, and behavioral data are combined and validated against observer ratings. An automated gaze‐labeling strategy is introduced, and supervised classifiers achieve high accuracy. The study supports scalable engagement

Research on the timing synchronization technology for PLC based on preamble sequence
Dianzi Jishu Yingyong, 2018 Because people do not consider the requirement of communication in the construction of power line, that resulting in the poor channel environment and the orthogonality between the sub-carriers are damaged.

Advanced Science, EarlyView.This study combines full‐field tomography with diffraction mapping to quantify radial (ε002$\varepsilon _{002}$) and axial (ε100$\varepsilon _{100}$) lattice strain in wrinkled carbon‐fiber specimens for the first time. Radial microstrain gradients (−14.5 µεMPa$\varepsilon \mathrm{MPa}$−1) are found to signal damage‐prone zones ahead of failure, which ...

Advanced Science, EarlyView.ABSTRACT Autism Spectrum Disorder (ASD) is associated with gut microbiota dysbiosis, yet the contribution of specific microbial metabolic pathways remains unclear. Reanalysis of a public ASD cohort revealed reduced functional potential in microbial tryptophan oxidative metabolism.
