معرفی تکنولوژی abi prism

فناوری abi prism یک روش دقیق و بسیار سریع برای تعیین اندازه قطعات و توالی یابی dna و ترکیبی از بکارگیری نرم افزار، سخت افزار و مواد شیمیایی است که برای تجزیه dna فلوئورسنت شده با رنگ های مختلف بهینه شده است. مهمترین مزیت این فناوری این است که تا چهار رنگ مختلف برای نشان دار کردن dna قابل استفاده است و هر کدام از این رنگ ها حتی زمانی که همه آنها در داخل یک چاهک تزریق شوند قابل تمایز هستند...

Double Lorentzian atomic prism

We present an atomic prism spectrometer that utilizes the steep linear dispersion between two strongly absorbing hyperfine resonances of rubidium. We resolve spectral lines 50 MHz apart and, utilizing a larger part of the available spectrum than only between the two resonances, we spatially separate collinear pump, signal, and idler beams resulting from a four-wave mixing process. Due to the hi...

Viterbi training in PRISM

VT (Viterbi training), or hard EM, is an efficient way of parameter learning for probabilistic models with hidden variables. Given an observation y , it searches for a state of hidden variables x that maximizes p(x , y | θ) by coordinate ascent on parameters θ and x . In this paper we introduce VT to PRISM, a logic-based probabilistic modeling system for generative models. VT improves PRISM in ...

Attention and prism adaptation.

For both lateral displacement and rotation of the visual field, visual adaptation was reduced when subjects were required to perform a secondary cognitive task simultaneously with the primary exposure task of walking about hallways. Interference appeared to be independent of walking rate and occurred when the cognitive task was either mental imagery or mental arithmetic. A tentative model is pr...
