background: all-trans retinol is a biological antioxidantscavenging the ros in the cell culture. objectives: this studywas conducted to investigate the effect of all-trans retinol infertilization and culture medium on mouse embryo's developmentalcompetence. methods: this study was designed into twoexperiments. in the first experiment, in vitro mature oocytes wereco-cultured with sperm in fertil...

This paper addresses transition detection which consists in identifying the boundary between consecutive shots. In this work, we propose an approach to cope with transition detection in which we define and use a new dissimilarity measure based on the size of the maximum cardinality matching calculated using a bipartite graph with respect to a sliding window. The experiments have used two video ...

A number of models with various degrees of accuracy were proposed in the literature for the evaluation of the probability density function @df) of the direct detection receiver photocurrent in optically amplified communication systems in the presence of N incoherent homodyne interferers, e.g. most recently 111. Previous models neglect the crosstalk-crosstalk and amplified spontaneous emission (...

During a police chase on foot, a previously well police officer was hit mistakenly by a taser shot meant for the suspect. The taser gun had been fired once, sending 2 barbed darts into his upper back and occiput. Within seconds, the officer collapsed and experienced a generalized tonic-clonic seizure with loss of consciousness and postictal confusion. Subsequent magnetic resonance imaging scans...

Nowadays, faults and failures are increasing especially in complex systems such as Network-on-Chip (NoC) based Systems-on-a-Chip due to the increasing susceptibility and decreasing feature sizes. On the other hand, fault-tolerant routing algorithms have an evident effect on tolerating permanent faults and improving the reliability of a Network-on-Chip based system. This paper presents reliabili...

the aim of this study is experimental assay of sensitivity and stability of a bimetallic silver/gold spr sensor chip. this chip utilizes the sensitivity of the silver and the stability of the gold. moreover, the silver layer (instead of usual cr or ti layer) was used as an adhesive intermediate layer between the gold layer and the glass substrate. the optimization of the gold/silver thickness u...

An on-chip detection scheme for high frequency signals is used to detect noise generated by a quantum dot formed in a single wall carbon nanotube. The noise detection is based on photon assisted tunneling in a superconductor-insulator-superconductor junction. Measurements of shot noise over a full Coulomb diamond are reported with excited states and inelastic cotunneling clearly resolved. Super...

We have completed thefirst tests of a method to synchronize the clocks of networhd computers to the NIST time scale. The method uses a server computer to dkseminate the time to other clients on the same local-ureu network. The server is synchronized to NZST wing the ACTS protocol over a dial-up telephone line. The software in both the server and the clients comtructs a statistical model of the ...
