Using information from a recent Rb two-color photoassociation experiment, we evaluate the merits of fountain clocks based on Rb and Rb isotopes as alternatives to Cs and find that they offer significant advantages. In the case of Rb the collisionally induced fractional frequency shift is 15 times smaller than for Cs. This small shift is associated with a small difference in the triplet and sing...

Rose Bengal (RB) is a red synthetic dye that was initially used in the garment industry and has been used safely for decades as a corneal stain by ophthalmologists. Antineoplastic properties of RB have also been observed, though the mechanism of action remained to be elucidated. Recently, interest in RB as a therapeutic cancer treatment has increased due to significant anti-tumor responses with...

We study the problem of selecting between different mechanisms of supersymmetry breaking in the Minimal Supersymmetric Standard Model using current data. We evaluate the Bayesian evidence of four supersymmetry breaking scenarios: mSUGRA, mGMSB, mAMSB and moduli mediation. The results show a strong dependence on the dark matter assumption. Using the inferred cosmological relic density as an uppe...

the present study aimed to study guidelines for jihad-e-keshavarzi organization of gilan province to become learning organization through strengthening organizational citizenship behavior and attitudes of employees. a questionnaire based survey was applied to 159 employees estimated through stratified random sampling. the face and content validity of questionnaire was confirmed by panel of expe...

PURPOSE Management of Retinoblastoma (RB), a pediatric ocular cancer is limited by drug-resistance and drug-dosage related side effects during chemotherapy. Molecular de-regulation in post-chemotherapy RB tumors was investigated. MATERIALS AND METHODS cDNA microarray analysis of two post-chemotherapy and one pre-chemotherapy RB tumor tissues was performed, followed by Principle Component Anal...

The attentional blink (AB) and repetition blindness (RB) phenomena refer to subjects' impaired ability to detect the second of two different (AB) or identical (RB) target stimuli in a rapid serial visual presentation stream if they appear within 500 msec of one another. Despite the fact that the AB reveals a failure of conscious visual perception, it is at least partly due to limitations at cen...

Business applications composed of heterogeneous distributed components or Web services need mediation to resolve data and process mismatches at runtime. This paper describes mediation in IRS-III, a framework and platform for developing WSMO-based Semantic Web Services. We present our approach to mediation within Semantic Web Services and highlight the role of WSMO mediator types when solving mi...

This paper is concerned with the investigation of mediation between users and Web search engines and the impact of different modes of mediation on the Web search effectiveness. This involves the integration of explicit, implicit and hybrid modes of mediation within a content-based framework, facilitated by the adoption of the Vector Space Model. The work is supported by an experimental evaluati...

Estrogen treatment of MCF-7 human breast cancer cells allows the reinitiation of synchronous cell cycle progression in antiestrogen-arrested cells. Here, we report that progestins also reinitiate cell cycle progression in this model. Using clonal cell lines derived from progesterone receptor (PR)-negative MCF-7M13 cells expressing wild-type or mutant forms of PRA and PRB, we show that this effe...
