Secure Data Sharing With AdHoc [PDF]
, 2012 In the scientific circles, there is pressing need to form temporary and dynamic collaborations to share diverse resources (e.g. data, an access to services, applications or various instruments). Theoretically, the traditional grid technologies respond to

Advanced Science, EarlyView.Itch‐induced tick removal (IITR): An acquired neuroimmune mechanism, itch‐induced tick removal, develops after repeated tick exposure, mobilizing T cells and macrophages at the tick bite site to trigger a rapid scratching response that facilitates timely tick removal within a critical window that precedes the transmission of many tick‐borne pathogens ...

[[alternative]]The Design of Group-Oriented Proxy Signature Schemes with Anonymous Proxy Group [PDF]
計畫編號：NSC93-2213-E032-020研究期間：200408~200507研究經費：428,000[[abstract]]Mambo 等學者在1996 年，首次提出了代理簽章的概念。在代理簽章法 中，原始簽章者，能委託一個代理簽章者為其產生代理簽章。因應實際群 體導向應用的需求，產生了多人授權代理簽章法、代理多人簽章法、多人 授權多人代理簽章法、門檻式代理簽章法與門檻式代理門檻式簽章法。在 已知的提出的代理簽章法中，有一種代理方式是：原始簽章者可以指明代 理人的身份，並委託他作為代理者。但是 ...

Advanced Science, EarlyView.The authors engineer colorectal cancer cells with reduced redundancy of UHRF1 and DNMT1, key DNA methylation maintenance factors, lowering the maintenance threshold and sensitizing cells to inhibition. They develop reporter assays driven by endogenous tumor‐suppressor gene promoters with enhanced sensitivity and dynamic range to demethylating drugs ...

Dual-proxy key-based threshold signature scheme for ship ad-hoc network
Tongxin xuebao, 2018 In order to solve the problem of message authentication under the conditions of the ship ad-hoc network (SANET),a signature scheme that does not depend on trusted certificate authorities and tamper-proof devices (TPD) was proposed by using the threshold ...

Advanced Science, EarlyView.Glutamine deprivation triggers transient DNA damage yet activates adaptive repair in hepatocellular carcinoma cells. We identify TRIB3 as a stress‐induced nuclear scaffold that associates with DDX5 and G‐quadruplex DNA atBRCA1 andRAD51AP1 promoters. TRIB3 loss increases G4 accumulation, suppresses HR gene transcription, elevates γ‐H2A.X, and sensitizes

Cryptanalysis of the Hwang-Shi Proxy Signature Scheme [PDF]
[[abstract]]Recently, Hwang and Shi proposed an efficient proxy signature scheme without using one-way hash functions. In their scheme, an original signer needn't send a proxy certificate to a proxy signer through secure channels.

Advanced Science, EarlyView.Protein complexes like KIBRA‐PKMζ are crucial for maintaining memories, forming month‐long protein traces in memory‐tagged neurons, but conventional RNA‐seq analysis fails to detect their transcript changes, leaving memory molecules undetected in the shadows of abundantly‐expressed genes.

Advanced Science, EarlyView.Zhang et al. identify M7core, a critical cGAS‐STING pathway‐driven gene signature that is activated in most lupus patients’ blood and links to lupus disease severity, lymphopenia, and lupus nephritis. They further reveal the diagnostic and pathogenic characteristics of M7core and emphasize the importance of assessing pathway activity before initiating ...

Hierarchical Artificial Muscle with Nonlinear Elasticity for Antagonistic and Cyclic Robotics
Advanced Science, EarlyView.We construct hierarchical muscles by plying nylon fibers around a heating wire. The hierarchical muscle shows a J‐shaped passive curve, which shows benefit in antagonistic muscle pair and work accumulation mechanism. We also develop a computational, first‐principle model to understand the physics of both active actuation stroke and passive J‐curve ...
