سابقه و هدف : سقط خود بخودی مکرر به مواردی اطلاق می گردد که حداقل 3 سقط خودب ه خودی پشت سر هم اتفاق افتاده باشد. با توجه به بالا بودن شیوع سقط مکرر در جامعه و متفاوت بودن میزان مقاومت شریان رحمی در مقالات مختلف و همچنی ن عدم بررسی شریان تخمدانی در کشور ما، مطالعه ای حاضر با هدف بررسی میزان مقاومت شرایین رحمی و تخمدانی زنان با سقط مکرر در فاز میدلوتئال و مقایسه آن با زنان بارور نرمال انجام شد. م...
motivated by the terminal wiener index, we define the ashwini index $mathcal{a}$ of trees as begin{eqnarray*} % nonumber to remove numbering (before each equation) mathcal{a}(t) &=& sumlimits_{1leq i&+& deg_{_{t}}(n(v_{j}))], end{eqnarray*} where $d_{t}(v_{i}, v_{j})$ is the distance between the vertices $v_{i}, v_{j} in v(t)$, is equal to the length of the shortest path start...
the sadhana index (sd) is a newly introduced cyclic index. efficient formulae for calculatingthe sd (sadhana) index of linear phenylenes are given and a simple relation is establishedbetween the sd index of phenylenes and of the corresponding hexagonal sequences.
The first reformulated Zagreb index $EM_1(G)$ of a simple graph $G$ is defined as the sum of the terms $(d_u+d_v-2)^2$ over all edges $uv$ of $G .$ In this paper, the various upper and lower bounds for the first reformulated Zagreb index of a connected graph interms of other topological indices are obtained.
There are two basic mysteries about natura l language. The speed and ease with which i t is acquired by a ch i ld and the speed and ease with which i t is processed. S i m i l a r l y to language acqu is i t i on , language processing faces a strong inpu t -da ta -de f i c iency problem.

Resistance develops due to mutations in the reverse transcriptase gene of HIV-1 genome that does not respond towards the presence of effective drugs. Emergence of HIV-1 variants in the presence of effective drugs is a common occurrence. Drug resistance mutation means “the development of resistance mutations in the drug targeted HIV-1 genes” which causes the viruses to overcome the drug pressure...
