یکی از روشهای برآورد پارامتر در حالتی که مشاهدات به طور کامل در دسترس باشند، روش برآورد ماکزیمم درستنمایی (maximum liklihood estimate) است . زمانی که مشاهدات به طور کامل موجود نباشد که فقدان قسمتی از داده ها ممکن است مقادیر گمشده و یا از مکانیزم سانسور کردن و ... ناشی شده باشد، بدست آوردن ماکزیمم درستنمایی (mle) کاربی بس دشوار است . الگوریتم em، یکی از ابزاری است که در این زمینه کارآیی وسیعی دا...

Two different metrics are used to assess Forster resonance energy transfer (FRET) between fluorophores in the steady state: (i) acceptor-quenching of donor fluorescence E (also known as transfer efficiency) and (ii) donor-excited acceptor fluorescence F(A) (Dex). While E is still more widely used, F(A) (Dex) has been gaining in popularity for practical reasons among experimentalists who study b...

A faunistic survey of Euphorinae (Hym., Braconidae) in southern Iran, as well as an updated checklist of the genera and species in Iran, are presented. Sampling was performed using Malaise traps at different locations of Hormozgan province and Qeshm Island in Persian Gulf during 2011-2013. In total, 38 species belonging to 10 genera are listed from Iran. The recorded species belong to the follo...

Long distance excitation energy transfer between a donor and an acceptor embedded in a polymer chain is usually assumed to occur via the Forster mechanism which predicts a R distance dependence of the transfer rate, where R is the distance between the donor and the acceptor. In solution R fluctuates with time. In this work, a Brownian dynamics simulation of a polymer chain with Forster energy t...

Two experiments investigated whether priming due to a match in just the onset between a masked prime and target is found with high-frequency target words. Forster and Davis (1991, Exp. 5) reported that the masked onset priming effect was absent for high-frequency words and used the finding to argue that the effect has its locus in the grapheme-phoneme mapping process that operates serially with...

Technical Report GT-IRIM-CP&R-2015-001 Christian Forster, Luca Carlone, Frank Dellaert, and Davide Scaramuzza May 30, 2015 This report provides additional derivations and implementation details to support the paper [4]. Therefore, it should not be considered a self-contained document, but rather regarded as an appendix of [4], and cited as: “C. Forster, L. Carlone, F. Dellaert, and D. Scaramuzz...

We have studied the influence of excess protons on the vibrational energy relaxation of the O-H and O-D stretching modes in water using femtosecond pump-probe spectroscopy. Without excess protons, we observe exponential decays with time constants of 1.7 and 4.3 ps for the bulk and anion bound O-D stretch vibrations. The addition of protons introduces a new energy relaxation pathway, which leads...
