Advanced Science, EarlyView.ABSTRACT Osteoarthritis (OA) is a widespread degenerative joint condition marked by progressive cartilage breakdown, and a chronic inflammatory microenvironment, where conventional therapies largely fail to halt disease progression. To address this unmet need, an intra‐articularly implantable, disease‐responsive scaffold was developed for combinatorial

Optimization of preimage resistance on SHA-3 algorithm(SHA-3算法的抗原象攻击性能优化)
Zhejiang Daxue xuebao. Lixue ban, 2016 通过对SHA-3算法置换函数Keccak-f的线性性质以及缩减轮数的Keccak杂凑函数原象攻击的研究，提出了 SHA-3算法的抗原象攻击性能优化设计方案.首先结合Keccak杂凑函数的差分特点和θ置换函数的奇偶性质，分析了基于CP-kernel的SHA-3算法原象攻击；然后针对目前实施原象攻击的方法，在θ置换函数运算后异或随机数以打乱其汉明重量，改变CP-kernel的校验性质，阻止攻击者利用中间相遇的方法寻找原象，提高了 SHA-3 算法的抗原象攻击能力；最后利用VHDL硬件语言实现抗原象攻击SHA-

Preimage Attacks on the Round-reduced Keccak with Cross-linear Structures
IACR Transactions on Symmetric Cryptology, 2017 In this paper, based on the work pioneered by Aumasson and Meier, Dinur et al., and Guo et al., we construct some new delicate structures from the roundreduced versions of Keccakhash function family. The new constructed structures are called cross-linear

Visualizing Elements of Sha[3] in Genus 2 Jacobians [PDF]
, 2010 Mazur proved that any element xi of order three in the Shafarevich-Tate group of an elliptic curve E over a number field k can be made visible in an abelian surface A in the sense that xi lies in the kernel of the natural homomorphism between the cohomology groups H^1(k,E) -> H^1(k,A).

Advanced Science, EarlyView.ABSTRACT Current clinical approaches for knee cartilage repair are often limited by hypertrophy and fibrosis in the regenerated tissues. A decellularized tissue‐engineered hyaline cartilage graft (dLhCG), composed of a type II collagen‐based extracellular matrix, has been developed to overcome this limitation.

Mechanically Reprogrammed Coaxial Fibers for Multiphysics Transduction and Human‐Machine Interfaces
Advanced Science, EarlyView.A continuously wet‐spun coaxial fiber is developed to combine stretchable conductivity, resistive sensing, and self‐powered triboelectric sensing in a single architecture. A mechanically reprogrammed dual‐network sheath stabilizes large deformation and improves signal reliability. These fibers can be woven into textile interfaces for multichannel touch

Side-Channel Analysis of Six SHA-3 Candidates [PDF]
, 2010 In this paper we study six 2nd round SHA-3 candidates from a side-channel cryptanalysis point of view. For each of them, we give the exact procedure and appropriate choice of selection functions to perform the attack. Depending on their inherent structure and the internal primitives used (Sbox, addition or XOR), some schemes are more prone to side ...

Advanced Science, EarlyView.Repurposing the dense tumor stroma from a physical barrier into an anchoring scaffold, an engineered oncolytic adenovirus encoding IL15C‐CBD overcomes the immunosuppressive microenvironment in triple‐negative breast cancer. Intratumoral viral replication secretes this collagen‐anchored immunocytokine, forming a localized cytokine depot.

Advanced Science, EarlyView.Sarcopenia has emerged as a major health challenge in the aging population. Developing a sustained‐release system for whey protein may enhance its effectiveness in mitigating sarcopenia. Herein, a novel “single‐protein particle encapsulation” (SPPE) system is developed to protect whey protein and control its release.
