In this study, we evaluated various parameters of sperm cryopreservation in two livebearers, guppies (Poecilia reticulata) and black mollies (P. latipinna). Our results suggested a common freezing protocol for the guppies and mollies: suspend sperm in Hanks' balanced salt solution (HBSS) at 300 mOsm/kg, use 14% glycerol as cryoprotectant, cool at 25 degrees(More)
Bayesian Network (BN) is one of the most popular models in data mining technologies. Most of the algorithms of BN structure learning are developed for the centralized datasets, where all the data are gathered into a single computer node. They are often too costly or impractical for learning BN structures from large scale data. Through a simple interface(More)
The developmental and reproductive toxicity of bisphenol A (BPA) has been demonstrated in a variety of model systems. Zebrafish (Danio rerio) were waterborne-exposed to BPA during three different developmental stages: embryonic period:6 h post fertilization (hpf) to 5 months post fertilization (mpf); larval period: 6 days post fertilization (dpf) to 5 mpf;(More)
Echo hiding algorithm is a type of Information hiding technology which has been widely used. This paper introduces the principle and the mathematical model of echo hiding algorithm. Generally, the traditional echo hiding algorithm just allows to hide 180 bits of information in 1 second, in order to increase the hiding capacity, we proposed multiple delayed(More)
BACKGROUND The high incidence and damage of PAD in people with diabetes has aroused wide attention. We aimed to examine effects of percutaneous lower-extremity arterial interventions (PLEAIs) on endothelial function and inflammation response in type 2 diabetes (T2D) patients with lower-extremity peripheral arterial disease (PAD). METHODS 78 T2D inpatients(More)
Inspired by the fact that online Public Relations (online PR) companies manipulate the online information and confuse people about the truth of information, a novel problem of identifying messages that are controlled by online PR companies is presented. Combined with the knowledge of characteristics of opinion leaders, methods of agenda setting and strategy(More)
