In 2005, Wen et al. proposed the first provably secure three-party password-based authenticated key exchange using Weil pairings, and provided their proof in a modified Bellare-Rogaway model (BR-model). Here, we show an impersonation attack on Wen et al.’s scheme and point out a main flaw of their model that allows a man-in-the-middle adversary easily violate the security.

This paper deals with the determination of the conditions for which the hysteretic Bouc-Wen model is consistent with the physical phenomenon it is supposed to represent. In particular, we derive the conditions on the model parameters under which the model is stable, asymptotically dissipative and verifies the hysteretic property. These conditions are in the form of algebraic inequalities to be ...

This paper established the equivalent linear motion equation of TRMD. To further investigate potential application TRMD in nonlinear vibration, Bouc-wen model structure with is provided, vibration control efficacy and hysteretic characteristics main under harmonic excitation are analyzed. The results show that suppresses displacement while loop energy dissipation capacity itself reduced. For so...

The genus Nekemias (Vitaceae) was first recognized by Rafinesque in 1838. It has been treated as a synonym of Ampelopsis Michx. Recent phylogenetic studies suggest that Ampelopsis as traditionally delimited is paraphyletic. To maintain the monophyly of each of the genera of Vitaceae, we herein segregate the Ampelopsissect.Leeaceifoliae lineage from Ampelopsis and recognize these taxa in Nekemia...

Amyotrophic lateral sclerosis (ALS) is an adult-onset neurodegenerative disease characterized by the selective loss of motor neurons. There is no effective treatment or drug against ALS, and the precise mechanisms leading to the selective loss of motor neurons are still unknown. We investigated the effect of a Chinese prescription, Wen-Pi-Tang, on the ALS model mouse SOD1(G93A). Although the or...

A taxonomic synopsis of the Altingiaceae is presented, including the taxonomic enumeration and distribution of 15 recognized species based on studies of 1,500 specimens from 24 herbaria throughout the distributional range of the taxa. Previous phylogenetic analyses based on several molecular markers have shown that Altingia and Semiliquidambar are nested within Liquidambar. All Altingia and Sem...
