Hatching seeds before they’re counted

Verifying Reference Counted Objects

Reference counting is a pervasive resource management idiom where each resource contains a count of the number of clients that hold a reference to it, and each client increments (resp., decrements) the count on acquiring (resp., releasing) the resource. If the reference count falls to zero, the system can reclaim the resource. Reference counting is often a source of subtle bugs, ranging from le...

Not everything that counts can be counted; not everything that can be counted counts.

Hardware Counted Profile-Guided Optimization

Profile-Guided Optimization (PGO) is an excellent means to improve the performance of a compiled program. Indeed, the execution path data it provides helps the compiler to generate better code and better cacheline packing. At the time of this writing, compilers only support instrumentation-based PGO. This proved effective for optimizing programs. However, few projects use it, due to its complic...

Hatching status before embryo transfer is not correlated with implantation rate in chromosomally screened blastocysts.

STUDY QUESTION Do the reproductive outcomes from the transfer of fully hatched (FH) blastocysts differ from those of not fully hatched (NFH) blastocysts? SUMMARY ANSWER Biochemical pregnancy rate (BPR), implantation rate (IR), live birth rate (LBR) and early pregnancy loss (EPL) rate are similar in FH and NFH single euploid blastocyst embryo transfers. WHAT IS KNOWN ALREADY The use of exten...

Effect of ethanolic extract of Melia azedarach L. seeds on oviposition and egg hatching of Tetranychus urticae (Acari: Tetranychidae)

Background & Aim: Tetranychus urticae Koch is one of the most important pests of crops, ornamental and greenhouse plants in the world and, can damage to 900 plant species. Resistances to pesticides and acaricides have guided researches to introduce new methods to control T. urticae. Botanical pesticides are an important group of natural productions that are usually safer than ...
