Equidistribution of Descents, Adjacent Pairs, and Place-Value Pairs on Permutations
An (X, Y )-descent in a permutation is a pair of adjacent elements such that the first element is from X, the second element is from Y , and the first element is greater than the second one. An (X, Y )-adjacency in a permutation is a pair of adjacent elements such that the first one is from X and the second one is from Y . An (X, Y )place-value pair in a permutation is an element y in position ...

چکیده: نسبت به کارکرد و ماهیت دیپلماسی عمومی در جهان امروز نظریه های متعددی بیان گردیده و جایگاه آن در کنار نظریه های دیگر در محافل آکادمیک و دانشگاهی بررسی و تحلیل گردیده است. نظر به اهمیت دیپلماسی عمومی و جایگاه آن در سیاست خارجی ایران این نوشتار با تمرکز بر دیپلماسی عمومی در منطقه آسیای مرکزی تهیه و تنظیم شده است. این ضرورت از آنجا ناشی می شود که اولاً مفهوم دیپلماسی عمومی در سیاست خارجی ای...
15 صفحه اولIn-place Recursive Approach for All-pairs Shortest Paths Problem Using Opencl
The all-pairs shortest paths (APSP) problem finds the shortest path distances between all pairs of vertices,and is one of the most fundamental graph problems. In this paper, a parallel recursive partitioning approach to APSP problem using Open Computing Language (OpenCL) for directed and dense graphs with no negative cyclesbased on R-Kleene algorithm, is presented, which recursively partitions ...
متن کاملDesign of An Intelligent Model for Strategic Planning in Mineral Holding: Case study, Shahab-Sang Holding
Business logic is one of the most important logics based on the decision matrix. However, using this logic alone and environmental uncertainty leads to problems such as low accuracy and integrity in strategic planning. In this work, we use an intelligent model based on the neural-fuzzy approach aiming at a desired decision-making and reducing the uncertainty in the strategic planning in mineral...
متن کاملA Guide to Fluorescent Protein FRET Pairs
Förster or fluorescence resonance energy transfer (FRET) technology and genetically encoded FRET biosensors provide a powerful tool for visualizing signaling molecules in live cells with high spatiotemporal resolution. Fluorescent proteins (FPs) are most commonly used as both donor and acceptor fluorophores in FRET biosensors, especially since FPs are genetically encodable and live-cell compati...
