Detection of new designer drugs remains an analytical challenge because of the ability of manufacturers to rapidly substitute closely related analogs for banned substances. Traditional targeted mass spectrometry methods rely on library searches, known masses, or multiple reaction monitoring (MRM) transitions and are therefore often unable to detect or identify recently discovered or yet unrepor...

We present the calculation of multiphoton radiation effects in leptonic W -boson decays in the framework of the Yennie–Frautschi–Suura exclusive exponentiation. This calculation is implemented in the Monte Carlo event generator WINHAC for single W -boson production in hadronic collisions at the parton level. Some numerical results obtained with the help of this program are also presented. To be...

The author investigated the conditions under which a congruent or incongruent orientation word affects processing of the orientation of visual objects. Participants named the orientation of a rectangle that partially occluded another rectangle. Congruent or incongruent orientation words appeared in the relevant object, in the irrelevant object, or in the background. There were two main results....

Secchi depth has been measured in Lake Tahoe an average of every 12 d since July 1967. Because of the unusual clarity of the lake, Secchi depth measurement is responsive to small changes in light-attenuating particles, and the record exhibits strong variability at the seasonal, interannual, and decadal scales. Using recently developed methods of applied time-series analysis, the mechanisms of c...

A panel of mouse anti-melanoma monoclonal antibodies (MoAb) were analyzed for reactivity with human melanoma cells singly and in combination. Five MoAb, ZME-018, 96.5, P94, 4.2, and 5.1, reactive with individual cell surface melanoma-associated antigens were tested with seven melanoma cell lines and seven fresh tumor biopsies. Cells were incubated with the MoAb, indirectly stained with fluoresc...

Text classification has increasing potential applications in many aspects of information world, such as recommender systems and customer service. The goal of this assignment is to apply Naive Bayes classifier to a data set of labeled textual movie reviews and practice Scala/ScalaNLP. The data set “Polarity dataset v2.0” is from http://www.cs.cornell.edu/People/pabo/movie-reviewdata/, created by...
