We study the electromagnetic form factors of the nucleon in a collective model of baryons. In an algebraic approach to hadron structure, we derive closed expressions for both elastic and transition form factors, and consequently for the helicity amplitudes that can be measured in electroand photoproduction.

Nucleon generalized polarizabilities are investigated within a relativistic framework, defining such quantities through a Lorentz covariant multipole expansion of the amplitude for virtual Compton scattering. The key physical ingredients in the calculation of the nucleon polarizabilities are the Lorentz invariant reduced matrix elements of the electromagnetic transition current, which can be ev...

Past research has demonstrated that infants can rapidly extract syllable distribution information from an artificial language and use this knowledge to infer likely word boundaries in speech. However, artificial languages are extremely simplified with respect to natural language. In this study, we ask whether infants' ability to track transitional probabilities between syllables in an artificia...

When estimating the influence of sentence complexity on reading, researchers typically opt for one two main approaches: Measuring syntactic (SC) or transitional probability (TP). Comparisons predictive power both approaches have yielded mixed results. To address this inconsistency, we conducted a self-paced reading experiment. Participants read sentences varying complexity. From alternatives, s...

BACKGROUND HIV-1-positive patients clear the human papillomavirus (HPV) infection less frequently than HIV-1-negative. Datasets for estimating HPV clearance probability often have irregular measurements of HPV status and risk factors. A new transitional probability-based model for estimation of probability of HPV clearance was developed to fully incorporate information on HIV-1-related clinical...

The length and structure of the transitional zone in the tunica media in the renal artery of adult male cats were investigated. In addition, the volume of the lumen and different layers in transitional and nontransitional zones in the right and left sides were also determined. Morphometrical, histological and stereological studies were performed on 16 renal arteries of 8 adult male cats. After ...

Introduction Recent studies suggest that young infants possess powerful statistical learning mechanisms that they can use to find word boundaries in fluent speech. For example, in a landmark study by Saffran, Aslin, and Newport (1996), the Headturn Preference Procedure was used to familiarize English-learning 8-month-olds to an artificial language containing no cues to word boundaries other tha...
