Based on bilinear pairing and three complicated problems,a new digital multi-signature scheme was pro-posed.In the new scheme,the advantage of fast signature in broadcasting digital multi-signature was applied to se-quential digital multi-signature.By changing the general mechanism of signature,signing could be done simultane-ously by the signers.T
Ventilated air flow in an enclosure is often unsteady (turbulent) at even very low Reynolds number (Re).Meantime natural convection in Frame Lamp a box is stationary motion at large enough Rayleigh number (Ra).This paper deals with the interaction between two those flows in a two-dimensional room.The room has one inlet and one or two outlets.A heat
Strokes in the distribution of the posterior circulation may present with vertigo, imbalance, Fleeces and nystagmus.Although the vertigo due to a posterior circulation stroke is usually associated with other neurologic symptoms or signs, small infarcts involving the cerebellum or brainstem can develop vertigo without other localizing symptoms.Appro
Sample preparation is key to the success of proteomics studies.In the present study, two sample preparation methods were tested for their suitability on the mature, recalcitrant leaves of six representative perennial plants (grape, plum, pear, peach, orange, and ramie).An improved sample preparation method was obtained: Tris and Fleeces Triton X-10
