Four reaction time experiments examined the mental rotation process using a psychological refractory period paradigm. On each trial, participants made speeded responses to both a tone (S1) and a rotated letter (S2), presented with varying stimulus onset asynchronies (SOAs). If mental rotation of the stimulus letter can proceed while central mechanisms are busy with S1, then the effect of orient...

We present a new methodology to derive faster composite operations of the form dP + Q, where d is a small integer ≥ 2, for generic ECC scalar multiplications over prime fields. In particular, we present an efficient Doubling-Addition (DA) operation that can be exploited to accelerate most scalar multiplication methods, including multiscalar variants. We also present a new precomputation scheme ...

the present paper investigates the effect of production factors, including technology, physical capital and labour on the energy consumption intensity of iran. for this purpose, time series data during the period of (1974-2007) have been analyzed within cobb–douglas production function framework. the results of the study indicate that the technology and the physical capital have caused the aver...

this article analyzed the various bibliometric components of the articles published in the malaysian journal of library and information science from 1996 to 2012. various quality aspects of the 279 articles published in the period were studied. the study demonstrates and elaborates on the various aspects of the journal, such as its distribution of article by year, authorship patterns, distribut...

Diamond's study compares the citation time series for Schumpeter and Keynes from 1956 to 2006. Citations steadily increase throughout period, whereas citations begin level off then trend slightly downward beginning in 1990s. As a result, outstrip those Keynes. This paper replicates extends analysis 2017, incorporating since onset of Great Recession. The replication confirms results study. beyon...

Publicly owned companies, their officers and major investors are required to file regular disclosures with the Securities and Exchange Commission (SEC). To improve accessibility to these public documents, the SEC began developed the EDGAR (Electronic Data Gathering, Analysis and Retrieval) electronic disclosure system. This system provides ready, free access to all electronic filings made since...

THE INCIDENCE of atrioventricular dissociation and Stokes-Adams seizures has been variously estimated. Rowe and White reviewed 160,000 electrocardiograms taken at the Massachusetts General Hospital from 1925 to 1955 and discovered 350 patients who showed complete atrioventricular dissociation. Penton, Miller, and Levine reported 251 cases of complete heart block during a 42 year period. In Rowe...

The incidence of hydatid disease varies considerably in different parts of the world. It is common in South America, Australia and parts of Asia; for example, in Beirut, Syria, 0 75o% of hospital admissions over a 10-year period were patients with echinococcus cysts (Baurys, 1952). In Great Britain there are no figures of value about the incidence of hydatid disease because there is no proper s...
