After the Arab-Muslim conquest (c. 650 CE), what we know of Middle Persian literacy in territory known as Ērānsahr is still little documented. Precisely, there evidence about linguistic developments during first two centuries but for an extract allegedly written by ibn al-Muqaffa. Most scholars’ debate on this passage based studied – mainly, inscriptions found south western part Sasanian empire...

Abstract. Given a doubling measure μ on R, it is a classical result of harmonic analysis that Calderón-Zygmund operators which are bounded in L(μ) are also of weak type (1, 1). Recently it has been shown that the same result holds if one substitutes the doubling condition on μ by a mild growth condition on μ. In this paper another proof of this result is given. The proof is very close in spirit...

A change in subtask order in the psychological refractory period (PRP) paradigm increases the effect of stimulus onset asynchrony (SOA) on the second response. We used a paradigm with cued, randomly determined subtask order to test the hypothesis that this SOA by order switch overadditivity reflects order control, via "copying" stimulus order. In Experiments 1a and 1b, overadditivity was eviden...

Introduction. The article is devoted to Persians who served in the Early Byzantine armed forces. Even during Principate period, alae and cohortes which were originally recruited from Parthians part of Roman imperial army. Units Persian defectors prisoners also created 4th 6th century. Methods. Using tools positivist methodology makes it possible provide a critical analysis information sources. ...

M. R. Jackson Bonner states that his narrative of Sasanian political history has been written for a general audience by avoiding academic debates and historiographical digressions. This much needed handbook consists nine chapters in which is assessed within the context all its neighbours; from Iberian territories, to Armenian struggles, Chinese embassies, relationships with nomads Hira, develop...

Although dual-task interference is ubiquitous in a variety of task domains, stop-signal studies suggest that response inhibition is not subject to such interference. Nevertheless, no study has directly examined stop-signal performance in a dual-task setting. In two experiments, stop-signal performance was examined in a psychological refractory period task, in which subjects inhibited one respon...

The standard bottleneck model of the psychological refractory period (PRP) assumes that the selection of the second response is postponed until the first response has been selected. Accordingly, dual-task interference is attributed to a single central-processing bottleneck involving decision and response selection, but not the execution of the response itself. In order to critically examine the...

We generalize the classical Cayley-Dickson doubling process starting with a quaternion algebra over a field F by allowing the scalar in the doubling to be an invertible element in the algebra. We investigate the resulting eight-dimensional algebras over F and show that they are division algebras for all scalars chosen in D outside of the base field F , if D is a division algebra.

The hypothesis that episodic memory retrieval can occur in parallel with other cognitive processes was tested in 2 experiments. Participants memorized words and then performed speeded cued recall (Experiment 1) or speeded yes-no recognition (Experiment 2) in a dual-task situation. The psychological refractory period design was used: The participant was presented with a single test item at vario...
