The fading of radiation-sensitive p-channel metal-oxide-semiconductor field-effect transistors (known as RADFETs or pMOS dosimeters) over a long time period 10 years after irradiation has been investigated. Fading is, in addition to sensitivity, another characteristic radiation dosimeters. It is considered the recovery threshold voltage irradiated dosimeters during ambient annealing without gat...

Transformations of hand movements by tools such as levers or electronic input devices can invoke performance costs compared to untransformed movements. This study investigated by means of the Psychological Refractory Period (PRP) paradigm at which stage of information processing such tool-transformation costs arise. We used an inversion transformation, that is, the movement of the operating han...

Suppose g ≥ 1, and let α = (α1, . . . , αn) be a partition of 2g− 2, and let H(α) be a stratum of Abelian differentials, i.e. the space of pairs (M,ω) where M is a Riemann surface and ω is a holomorphic 1-form on M whose zeroes have multiplicities α1 . . . αn. The form ω defines a canonical flat metric on M with conical singularities at the zeros of ω. Thus we refer to points of H(α) as flat su...

In a number of field theoretical models the vacuum angle θ enters physics in the combination θ/N , where N stands generically for the number of colors or flavors, in an apparent contradiction with the expected 2π periodicity in θ. We argue that a resolution of this puzzle is related to the existence of a number of different θ dependent sectors in a finite volume formulation, which can not be se...

Three experiments examined the effects of task switching and response correspondence in a psychological refractory period paradigm. A letter task (vowel-consonant) and a digit task (odd-even) were combined to form 4 possible dual-task pairs in each trial: letter-letter, letter-digit, digit-digit, and digit-letter. Foreknowledge of task transition (repeat or switch) and task identity (letter or ...

The goal of this study was to assess the impact of individual neuropsychological differences on the ability to share attention between concurrent tasks. Participants (n = 20) were trained on six single task practice sessions and dual-task was assessed with reaction time performance on a psychological refractory period (PRP) paradigm. Neuropsychological test scores were also acquired. Furthermor...
