We study electrical modulation of transport properties silicene nanoconstrictions with different geometrical structures. investigate the effects position and width central scattering region on conductance increasing Fermi energy. It is found that significantly depends nanoconstriction. Interestingly, symmetrical structure constriction can induce a resonance effect increase systemʼs conductance....
abstract: the present study was undertaken to investigate whether 1) there is any significant correlation between iranian efl/eap learners’ l2 writing proficiency and their willingness to communicate, 2) there is any significant difference between efl and eap learners in terms of willingness to communicate, 3) there is any significant difference in wtc of iranian efl/eap learners with 1- nati...
We present a theoretical analysis of intracellular calcium waves propagated by calcium feedback at the inositol 1,4,5-trisphosphate (IP3) receptor. The model includes essential features of calcium excitability, but is still analytically tractable. Formulas are derived for the wave speed, amplitude, and width. The calculations take into account cytoplasmic Ca buffering, the punctate nature of th...
Chinese Digital Terrestrial/Television Multimedia Broadcasting (DTMB) systems use pseudo random noise (PN) sequence instead of cyclic prefix for channel estimation. This paper proposes threshold and CIR width detection methods to improve the channel estimation and shows that threshold method combined with averaging and PN correlation reduction method needs special care for high DUR condition an...
It was found in this paper that the dominant component of the wave function of the second 0 + state of 4 He and the corresponding component of the 3 H+p channel have different spatial permutation symmetries and different parities. This fact will hinder the wave function to extend from the interior region to the outgoing channel and will results in having a narrower width. The few-nucleon system...
abstract the variables affecting the nature of reading comprehension can be classified into two general categories: reader’s variables, and text variables (alderson, 2000). despite the wave of research on vocabulary knowledge as reader’s variable, the role of this knowledge in c-test as a text-dependent test and its interaction with lexical cohesion of the test as a text feature has remained a...
Joint effects of aperture averaging and beam width on the performance of free-space optical communication links, under the impairments of atmospheric loss, turbulence, and pointing errors (PEs), are investigated from an information theory perspective. The propagation of a spatially partially coherent Gaussian-beam wave through a random turbulent medium is characterized, taking into account the ...
Measurements studies show that there exist large spatial and temporal fluctuations in the traffic load handled by different access points in Wireless LANs. In order to alleviate this problem, researchers have proposed various load-balancing techniques based for instance on channel assignment, power control, or client allocation. Fundamentally, however, assigning each AP the same amount of bandw...
abstract following innovations in the field of elt, a new topic which has recently attracted a lot of attention is metaphor analysis. although this area of research is still in its infancy in elt, it seems that the idea can shed more light on the puzzle of english language learning and teaching. therefore, the major aim of this study is to analyze language learning and teaching in formal a...
it is not possible to understand developments of a country’s culture and civilization without knowing his believes and myths. whether it is north or south, east or west, planes or mountains, sahara or deserts, here in iran every corner includes valuable and precious treasures which are known all over the world, and cultural – historical objects which are found here adorn all well known museums...
