a parallel algorithm for generating t-ary tree sequences in reverse b-order is presented. the algorithm generates t-ary trees by 0-1 sequences, and each 0-1 sequences is generated in constant average time o(1). the algorithm is executed on a crew sm simd model, and is adaptive and cost-optimal. prior to the discussion of the parallel algorithm a new sequential generation with o(1) average time ...

In this work, it is presented iterative schemes for achieving to common points of the solutions set of the system of generalized mixed equilibrium problems, solutions set of the variational inequality for an inverse-strongly monotone operator, common fixed points set of two infinite sequences of relatively nonexpansive mappings and common zero points set of two finite sequences of maximal monot...

Studies on the evolutionary history of ascomycetes in terms of time scale will help to understand historical patterns that shape their biodiversity. Until now most of dating studies of ascomycetes have focused on major events in fungal evolution but not on divergence events within smaller groups of fungi e.g. within Sordariomycetes. We used molecular dating to estimate the time of separation of...

the asmari formation in tang-e surkh section is composed of 294 meters of thin to medium bedded and thick to massive bedded limestone associated with marly limestone. the studied section is located in the northwest of interior fars. based on deepening and shallowing patterns of microfacies, one hst and one third-order depositional sequence during rupelian and two third-order depositional sequen...

carnation etched ring virus (cerv) is a member of the caulimovirus genus of the caulimoviridae. the virus is the second most important virus of carnation around the world and the only dna virus among infecting viruses of carnation. the virus infected plants were collected from greenhouse in chenaran and two fragments of ~1500 bp and ~1000 bp respectively for coat protein and movement protein we...

background: traditionally, morphological features of rhipicephalus (boophilus) annulatus from closely-related ticks have been considered for their identification and differentiation. however, it is difficult and requires expertise in order to accurately identify and differentiate engorged female ticks and some developmental stages such as larva and nymph from other similar ticks. hence, molecul...

Abstract In this paper, we study the generalized order- Jacobsthal sequences modulo for and the generalized order-k Jacobsthal-Padovan sequence modulo for . Also, we define the generalized order-k Jacobsthal orbit of a k-generator group for and the generalized order-k Jacobsthal-Padovan orbit a k-generator group for . Furthermore, we obtain the lengths of the periods of the generalized order-3 ...

In this paper the notion of Rees short exact sequence for S-posets is introduced, and we investigate the conditions for which these sequences are left or right split. Unlike the case for S-acts, being right split does not imply left split. Furthermore, we present equivalent conditions of a right S-poset P for the functor Hom(P;-) to be exact.

The brain's decoding of fast sensory streams is currently impossible to emulate, even approximately, with artificial agents. For example, robust speech recognition is relatively easy for humans but exceptionally difficult for artificial speech recognition systems. In this paper, we propose that recognition can be simplified with an internal model of how sensory input is generated, when formulat...
