Functional Optical Fibers with Tailored Side Emission from Modified Rod‐in‐Tube Preforms

Advanced Photonics Research, EarlyView.
A modified rod‐in‐tube method enables fabrication of functional optical fibers with tailored light‐diffusing properties. The approach incorporates optically active species at a well‐defined radial position within an otherwise homogeneous fiber core. Using lanthanide ions and noble metal nanoparticles as active species demonstrates wavelength conversion

Bleeding‐Mimetic Damage‐Detecting and Self‐Healing Modular Skin for Inflatable Structures

Advanced Robotics Research, EarlyView.
A damage‐detecting and self‐healing system inspired by the human bleeding mechanism is developed for inflatable structures, using a liquid conductive elastomeric material enclosed in a small pouch. This material, composed of uncured elastomer, its curing agent, conductive particles, and a dispersant, solidifies only after being exposed to air and ...

Facile Functionalization of Separator with an Amino Acid to Boost Li–S Battery Performance

Advanced Sustainable Systems, EarlyView.
This study introduces a viable bio‐approach to functionalize conventional separators using leucine‐polyacrylic acid (Leu‐PAA) via the simple soaking method. This strategy synergistically improves polysulfide trapping, regulates lithium‐ion flux, and enhances thermal and mechanical stability, leading to excellent cycling stability.

Computation of blowing up centers

Journal of Pure and Applied Algebra, 2003
AbstractGiven a birational projective morphism of quasi-projective varieties f:Z→X. We want to find the ideal sheaf I over X such that the blowing up of X along I corresponds to f. In this paper we approach the problem from two directions, solving two subcases.

A Super‐Enhancer‐Driven Transcriptional Regulatory Circuit Underlying Abiraterone Resistance in Castration‐Resistant Prostate Cancer

Advanced Science, EarlyView.
This study identifies a super‐enhancer‐driven transcriptional regulatory circuit comprising BCL6, SMAD3, and NFIB that cooperate to drive cholesterol synthesis via SREBF2/HMGCR/FDFT1 activation and regulate CDK2/CCND3 for cell cycle control. Targeting this circuit with BI‐3802 or downstream inhibitors (Fatostatin/Lovastatin) overcomes abiraterone ...

Diurnal Release of Airborne Pathogen Spores in Greenhouses via the Synergistic Effects of Relative Humidity and Wind

Advanced Science, EarlyView.
Day‐night cycles trigger sharp relative humidity (RH) shifts in greenhouses. Rapid humidity drops dehydrate Corynespora cassiicola spores, inducing shrinkage, jerking movements, and weakened inter‐spore connections that drive detachment. Wind is essential for dispersal, with even mild airflow enabling rapid pathogen spread. These synergistic effects of
