Kingman's coalescent process opens the door for estimation of population genetics model parameters from molecular sequences. One paramount parameter of interest is the effective population size. Temporal variation of this quantity characterizes the demographic history of a population. Because researchers are rarely able to choose a priori a deterministic model describing effective population si...

The measure contraction property, MCP for short, is a weak Ricci curvature lower bound conditions for metric measure spaces. The goal of this paper is to understand which structural properties such assumption (or even weaker modifications) implies on the measure, on its support and on the geodesics of the space. We start our investigation from the euclidean case by proving that if a positive Ra...

MCP (Modified Critical-Path) algorithm [1] schedules Directed Acyclic Graphs (DAGs) with communication costs onto a bounded number of processors. It is one of the six most popular algorithms in this category and performs the best among them [2]. MCP has many implementations during the last decade, while most of them did not implement it efficiently. In this paper, we present the methods to redu...

an investigation was carried out to study the effect of sole heat treatment and sole 1- methyl cyclo propine (1- mcp) as well as in combination on storage quality of strawberries. the factorial experiment was conducted using a completely randomized design of three replications. treatments included heat treatment at two levels (room teperature, 45°c for 3h) and 1- mcp at two levels (0, 1µl l-1)....

Micro-channel plate photomultiplier tube (MCP-PMT) is a kind of photosensitive device with single photon detection capability and great time resolution, which also called Fast-PMT (FPMT). The characteristic MCP makes the MCP-PMT capable reaching spatial resolution multi-anodes. With experience successfully R&D 20-inch MCP-PMT, researchers in IHEP are now developing multi-anodes FPMT resolut...
