Three species of genus Ascaphium are recorded from China, including Ascaphium longlingense He, Tang & Li, sp. nov. and A. ingentis He, Tang & Li, sp. nov. from Yunnan Province. The male of Ascaphium alticola Löbl is discovered and described for the first time. A key to Ascaphium species of China is provided.

Introduction Qing fei tang, which is used for various respiratory diseases, is useful for reducing relapse of aspiration pneumonia and bronchopneumonia in stroke, but the effect remains unknown in Parkinsonian’s syndrome. We report two cases of Japanese patients with progressive supranuclear palsy and relapsing aspiration pneumonia and bronchopneumonia, which was successfully prevented by qing ...

In [3], Tang presented two password guessing attacks such as off-line and undetectable on-line dictionary attacks against password-based group Diffie-Hellman key exchange protocols by Byun and Lee [2]. In this paper, we present countermeasures for two attacks by Tang.

We study avalanche dynamics on scale-free networks, following a power-law degree distribution, pd ðkÞ k ; through the Bak–Tang–Wiesenfeld sandpile model. The threshold height of a node i is set to be k 1 Z i with 0pZo1: We obtain the exponents for the avalanche size and the duration distributions analytically as a function of g and Z by using the branching process approach. The analytic solutio...

In this article we investigate the job Sequencing and tool Switching Problem (SSP), a NP-hard combinatorial optimization problem arising from computer andmanufacturing systems. Starting from the results described in Tang and Denardo (1987), Crama et al. (1994) and Laporte et al. (2004), we develop new integer linear programming formulations for the problem that are provably better than the alte...

If treated early, prostate cancer is usually curable. After metastasis occurs, however, these tumors become resistant to treatment and are generally fatal. Therefore, inhibiting metastasis may significantly improve the survival time for patients with prostate cancer. The Vasioukhin laboratory has previously shown that the host serine protease Hepsin promotes prostate cancer progression and meta...

In recent years, increasing attention has been focused on the study of dynamical systems, often with time delay, which model in population dynamics [Chen & Blackmore, 2002; Gopalsamy, 1992; Yang, 1993; Matin & Ruan, 2001; May, 1973], physics and mechanics [Cahlon et al., 1997], remote control [Ryabov, 1960], radiation damping [Chicone et al., 2001], and so on and so forth. Such systems attract ...

BACKGROUND Functional dyspepsia (FD) is characterized by a high prevalence rate and no standard conventional treatments. Alternative therapies, such as herbal formulas, are widely used to treat FD. However, there are inadequate evidences regarding the safety and efficacy of these formulas. Moreover, the mechanisms by which herbal formulas act in the gastrointestinal tract are controversial. In ...

Most modern organizations require individuals to work in teams to perform their tasks. Information systems development teams, advertising teams, and new product development teams are only a few examples from the business community. The group work environment creates challenges for the group members that may affect the group’s performance. The relevance and importance of group performance and it...
