Key insulation is an important technique to protect private keys. To deal with the signing key exposure problem in attribute-based signature systems, we propose an attribute-based threshold key-insulated signature (ABTKIS) scheme. It strengthens the security and flexibility of existing attribute-based key-insulated signature schemes. Our scheme is provably secure in the standard model (i.e. wit...

the effects of steel wire patenting process parameters on very fine interlamellar spacing in the pearlitic steel wire were investigated and the optimized condition of the process was achieved. in this work, the initial nanopearlitic structure was obtained in a 0.72 wt% carbon steel wire before the wire drawing process. the results were the minimum interlamellar spacing of 35 nm and maximum ulti...

In the history of life, cooperation between biological units has led to increased complexity, e.g., eukaryotic cells and multicellular organisms. Cooperation requires limiting gains “defectors” in favor cooperative higher-level unit. Early an evolutionary transition, bioenergetics reactive oxygen species (ROS) may play a large role managing these conflicts. Chemiosmosis can be thought as poorly...

Room-temperature vulcanized rubber is an excellent polymer material with electrical insulation and mechanical properties, which can be used for field of high-voltage bare wire. In this paper, a room-temperature cured coating was prepared from α,ω-dihydroxy polydimethylsiloxane (PDMS), polyurethane-modified silicone (PU-Si), Methyltris(methylethylketoxime) silane (MOS). The study showed that the...

Methods Isolated and cleaned squid giant axons were internally perfused by a modification of the method of Adelman and Gilbert (1964) and Adelman and Fok (1964). A chemically driven syringe (Sage Instruments) was directly connected to the axon interior through a small cut in one end by means of a 200,/ diameter glass cannula. The internal axoplasm was eroded away upon continuous internal fluid ...

the micro wire electrical discharge machining (micro wire-edm) process is a modern machining process with various applications in manufacturing micro-parts. the recast layer remaining on the machined surfaces is an inevitable complication of this process. this layer can subsequently affect the machined parts performance. to optimize the recast layer in the micro wire-edm of the molybdenum micro...

The size and length effects of an inclusion on multi-pass copper shaped-wire drawing were investigated. For this purpose, an experimental investigation on optimal die half-angle was conducted. Based on experimental data of optimal die half-angle, wire and inclusion deformations, drawing and hydrostatic stress of copper shaped-wires that contain an inclusion were calculated by two-dimensional fi...
