In human in-vitro fertilization (IVF) embryos are routinely transferred to the uterus on day 2 or day 3 of development. Resultant implantation and pregnancy rates are disappointingly low, with only approximately 10% of embryos transferred leading to a live birth. The ability to culture embryos to the blastocyst stage should help to resolve this problem by synchronizing the embryo with the femal...

OBJECTIVE To investigate whether early embryo cleavage kinetics were affected by type of culture media. METHODS In this prospective sibling-split study, 620 oocytes from 37 patients were randomly allocated into two groups: Cook group and Vitrolife group. Oocytes/embryos in Cook group, would be cultured with Cook sequential culture medium, while oocytes/embryos in Vitrolife group, would be cul...

Transfer at the blastocyst stage has been proposed to increase the pregnancy rates after in-vitro fertilization (IVF) and embryo transfer. In the first period of experiments, culture in a single medium, from fertilization to blastocyst led to disappointing results: low blastocyst formation rates and low implantation rates per blastocyst transferred. Then the period of co-culture began (starting...

The growth of the Web 2.0 technologies has led to an explosion of social networking media sites. Among them, Twitter is the most popular service by far due to its ease for realtime sharing of information. It collects millions of tweets per day and monitors what people are talking about in the trending topics updated timely. Then the question is how users can understand a topic in a short time w...

We demonstrate GRAPE, a parallel GRAPh query Engine. GRAPE advocates a parallel model based on a simultaneous fixed point computation in terms of partial and incremental evaluation. It differs from prior systems in its ability to parallelize existing sequential graph algorithms as a whole, without the need for recasting the entire algorithms into a new model. One of its unique features is that ...

This article is concerned with the formulation and numerical solution of equations for modelling multicomponent, two-phase, thermal fluid flow in porous media. The fluid model consists of individual chemical component (species) conservation equations, Darcy’s law for volumetric flow rates and an energy equation in terms of enthalpy. The model is closed with an equation of state and phase equili...

We present an empirical analysis of human behavior dynamics in online social media from a time sequential perspective. By analyzing the users’ inter-event time distribution between two consecutive actions and fitting with accurate numerical method, we find that the users’ behavior pattern follows the heavy tailed or power-law distribution both in collective and individual scale, not the traditi...

This paper attempts to ground the relationship of architecture to game space, suggest ways in which real world design of places can help the design of game spaces, and distinguish between our experience and recall of episodic space as scene via film and literature, to our experience and recall of sequential and interstitial space in three-dimensional games. The following argument is based on in...

INTRODUCTION The increasing prevalence of multi-resistant bacteria is a major public health concern. Infections acquired during ophthalmic surgery are devastating. The purpose of the current study is to compare the proportion of eyes with negative bacterial cultures on all tested media after 1 versus 3 sequential drops of povidone-iodine (PI) 5% into the inferior conjunctival fornix. METHODS ...
