paraschistura alta , formerly reported from the eastern part of sistan basin in afghanistan, is reported for the first time from the zahak river in iranian part of this basin and its morphological characteristics, coi barcode and its phylogenetic relationship within other members of the genus paraschistura from iran are provided. all the measured meristic and morphometric characters of seven co...

The presence of antibiotics in the environment is of great concern because of their potential for resistance selection among pathogens. In the present study we investigated the occurrence of 19 sulfonamides, five N-acetylated sulfonamide metabolites, and trimethoprim in the Liao River basin and adjacent Liaodong Bay, China, as well as 10 human/agricultural source samples. Within the 35 river sa...

The historical trends and inventory of organophosphate esters (OPEs) were investigated based on depth profiles OPEs in sediment core collected from the tidal flat Liao River estuary northeastern China. concentration ∑ 13 has increased continuously since records began, reaching a peak 10.8 ng g -1 dry weight (dw) 1960s, then began to decline fall low 3.91 dw 1980s, before rising again increasing...

In 2005, Liao et al. pointed out the weaknesses of Das et al.’s dynamic ID-based remote user authentication scheme using smart cards, and then proposed a slight modification thereof to overcome these weaknesses. The current paper, however, demonstrates that Liao et al.’s scheme is still vulnerable to reflection attacks, privileged insider’s attacks, and impersonation attacks by using lost or st...

Although the stability of neural networks has been studied by many authors, the problem of stochastic effects on the stability has not been investigated until recently by Liao and Mao [7, 8]. In this paper we shall investigate the stability problem for stochastic neural networks with time-varying delay. The main technique employed in this paper is the well-known Razumikhin argument, which is co...

The homotopy analysis method is used to find a family of solitary smooth hump solutions of the Camassa–Holm equation. This approximate solution, which is obtained as a series of exponentials, agrees well with the known exact solution. This paper complements the work of Wu & Liao [Wu W, Liao S. Solving solitary waves with discontinuity by means of the homotopy analysis method. Chaos, Solitons & ...

We present a counterexample to a lower bound for the power domination number given in Liao, Power domination with bounded time constraints, J. Comb. Optim. 31 (2016): 725–742. We also define the power propagation time, using the power domination propagation ideas in Liao and the (zero forcing) propagation time in Hogben et al, Propagation time for zero forcing on a graph, Discrete Appl. Math., ...

5 We present a counterexample to a lower bound for power domination number given in Liao, Power 6 domination with bounded time constraints, J. Comb. Optim., in press 2014. We also define the power 7 propagation time and make connections between the power domination propagation ideas in Liao and the 8 (zero forcing) propagation time in Hogben et al, Propagation time for zero forcing on a graph, ...
