This review traces the evolution of lithium‐ion battery separators from passive barriers to multifunctional components central to cell safety and performance. Polymer‐ceramic hybrids, nanofiber architectures, and bio‐derived membranes deliver ionic conductivities above 3 mS cm−1, thermal stability beyond 200 °C, and effective suppression of lithium ...

A Scalable Perovskite Platform With Multi‐State Photoresponsivity for In‐Sensor Saliency Detection
A scalable in‐sensor computing platform (32 × 32 array) with ultra‐low variability is developed by incorporating ferroelectric copolymers into halide perovskite thin films. These devices achieve 1000 programmable photoresponsivity states and high thermal reliability.

Hair keratin fibers inevitably deteriorate under UV exposure, heat, and dryness. A robust composite coating assembles delaminated Ti3C2 MXene nanosheets onto keratin surfaces through biocompatible metal‐polyphenol networks of EGCG. This hybrid layer simultaneously screens UV, dissipates heat, reinforces mechanical strength, suppresses static charge ...

A method of rice panicle number counting based on improved CSRNet model
IntroductionRice is one of the world's leading food crops, with nearly half of the world's population eating rice as their staple food. Rice yield is directly related to varieties, and the most intuitive agronomic trait of varietal yield is the number of

3D Printed Multimaterial Microfluidic Transistors
We introduce a biocompatible, high resolution photopolymer resin that closely mimics the Young's Modulus (elasticity) and reversible stretchability (no hysteresis) of poly(dimethylsiloxane) (PDMS), enabling the fabrication of microfluidic transistors (i.e., microvalves capable of proportional amplification) by multimaterial stereolithography (mSLA ...

Some remarks on a terminal value problem
Some theorems concerning the existence and uniqueness of solutions of the differential equations with deviating arguments \(x'(t)=f(t,x[\sigma_ 1(t)],...,x[\sigma_ k(t)]),\) which satisfy the ''terminal'' condition \(\lim_{t\to \infty}x(t)=\xi\) where \(\xi \in R^ n\) or \({\mathbb{C}}^ n\) are obtained.

Dynamic Mean–Variance Portfolio Optimization with Value-at-Risk Constraint in Continuous Time
Recognizing the importance of incorporating different risk measures in the portfolio management model, this paper examines the dynamic mean-risk portfolio optimization problem using both variance and value at risk (VaR) as risk measures. By employing the
