We have read with great interest the Advances in Stroke 2007 subsection in February’s issue of Stroke and congratulate Dr Fisher for nicely amalgamating articles addressing some of the most pressing advances and shortcomings in stroke management over the past year.1 Although advances in interventional approaches to stroke and neurovascular disease were nicely outlined,1,2 we noticed little emph...

Chesneau et al.(2020) considered the distributions of sum and differences two independent identically distributed random variables with common Lindley distribution. They derived, very nicely, above mentioned provided certain important mathematical statistical properties as well simulations applications new distributions. In this short note, we like to show that assumption ”independence” can be r...

We focus on a family of equalities pioneered by Zhang and generalized Zao Wang hence Mansour which involves self convolution Fibonacci numbers. show that all these formulas are nicely stated in only one equation involving bivariate ordinary generating function we give also formula for the coefficients appearing context. As consequence, general forms Zhang, Zao-Wang Mansour.

boron nitride semiconducting zigzag swcnt, $b_{cb}$$n_{cn}$$c_{1-cb-cn}$, as a potential candidate for making nanoelectronic devices was examined. in contrast to the previous dft calculations, wherein just one boron and nitrogen doping configuration have been considered, here for the average over all possible configurations, density of states (dos) was calculated in terms of boron and nitrogen ...

رز از مهمترین گیاهان زینتی و معطر دنیا محسوب می شود و به دلیل دارا بودن ترکیبات معطر؛کاربردهای فراوان در صنایع غذایی، داروسازی، آرایشی بهداشتی و عطرسازی دارد. عطر گل رز متشکل از بیش از 500 ترکیب مختلف است که متعلق به سه گروه ترپنوئیدها، فنیل پروپانوئیدها و مشتقات اسید چرب می باشند. مطالعه تفاوت ژن های بیان شده در رز های معطر و غیر معطر منجر به شناسایی چندین ژن کد کننده آنزیم های دخیل در سنتز مو...

edge distance-balanced graphs are graphs in which for every edge $e = uv$ the number of edges closer to vertex $u$ than to vertex $v$ is equal to the number of edges closer to $v$ than to $u$. in this paper, we study this property under some graph operations.

the emph{harary index} $h(g)$ of a connected graph $g$ is defined as $h(g)=sum_{u,vin v(g)}frac{1}{d_g(u,v)}$ where $d_g(u,v)$ is the distance between vertices $u$ and $v$ of $g$. the steiner distance in a graph, introduced by chartrand et al. in 1989, is a natural generalization of the concept of classical graph distance. for a connected graph $g$ of order at least $2$ and $ssubseteq v(g)$, th...

dna barcoding based on a standardized region of 648 base pairs of mitochondrial dnasequences from cytochrome c oxidase 1 (cox1) is proposed for animal species identification.recent studies suggested that dna barcoding has been effective for identifying 94% of birdspecies. the proposed threshold of 10 times the average intraspecific variation could be used forthe identification and delimitation ...

We have previously clarified that the strongly electron-withdrawing CF3 group nicely affected base-mediated proton shift of CF3-containing propargylic or allylic alcohols to afford corresponding α,β-unsaturated saturated ketones, respectively, which was applied this time Claisen rearrangement after O-allylation with a group, followed by isomerization allyl vinyl ethers via shift, enabling desir...
