we usewe use ml shear wave velocity to derive a high resolution 2d ml shear wave velocity map for the iranian plateau. the ml amplitudes and arrival times are routinely measured for the calculation of local magnitude. ml shear wave velocity is very sensitive to the lateral change of crustal thickness and switches between the velocity of lg and sn waves. an lg wave will die out as soon as encoun...
Given a string S, the compressed indexing problem is to preprocess S into a compressed representation that supports fast substring queries. The goal is to use little space relative to the compressed size of S while supporting fast queries. We present a compressed index based on the Lempel–Ziv 1977 compression scheme. We obtain the following time-space trade-offs: For constant-sized alphabets (i...
in this paper, we introduce a new model of point free topology for point-set topology. we study the basic concepts in this structure and will find that it is naturally close to point-set topology.
It is widely assumed that O(m+ lg σ) is the best one can do for finding a pattern of length m in a compacted trie storing strings over an alphabet of size σ, if one insists on linear-size data structures and deterministic worst-case running times [Cole et al., ICALP’06]. In this article, we first show that a rather straightforward combination of well-known ideas yields O(m+lg lg σ) deterministi...
The measurement of carbon isotope discrimination (∆) provides an integrated insight into theresponse of plants to environmental change. To investigate the potential use of ∆ for identifyingshade tolerance in rice, five rice varieties were selected and artificially shaded (53% lightreduction) during the grain-filling period in 2010 and 2011, in Sichuan, China. Shadingtreatment had a significant ...
AIMS To investigate the effect of LG100268 (LG268) on cell proliferation and apoptosis in NB4 cells. METHODS NB4 cells were treated with LG268 for 24 h or 48 h. The effect of LG268 on cell proliferation was assessed by the CCK-8 assay and colony-forming assay. Apoptosis and cell cycle were evaluated by flow cytometry. The protein expression levels of Survivin, PARP, c-Myc, cyclin D1, ERK, p-E...
Silicosis is an incurable occupational disease associated with inflammation, fibroblast proliferation and the accumulation of extracellular matrix in lung tissues. The dysregulation of lncRNAs and miRNAs has been implicated in many complex diseases; however, the current understanding of their roles in fibrotic lung diseases, especially silicosis, remains limited. Our previous microRNA (miRNA, m...
مراجعه به داوری، هم در داوری های محلی و هم در داوری های تجاری بین المللی، به این منظور صورت می گیرد که به خاطر پاره ای از مزایا، داور که شخص خصوصی منتخب طرفین اختلاف است، جایگزین قاضی شود. در حالی که، درخواست ابطال رأی داوری، با هدف داوری و همه مزایایی که برای داوری شناخته شده است، در تعارض است. با وجود این، در برخی مواقع ممکن است یکی از طرفین دعوا، رأی داوری را صحیح ندانسته و علت آن را تخلفاتی...
We define and design succinct indexes for several abstract data types (ADTs). The concept is to design auxiliary data structures that ideally occupy asymptotically less space than the information-theoretic lower bound on the space required to encode the given data, and support an extended set of operations using the basic operators defined in the ADT. The main advantage of succinct indexes as o...
در این مطالعه به منظور بررسی تغییرات جانبی ضخامت پوسته در ایران، با استفاده از روش توموگرافی لرزهای تغییرات سرعتِ گروه بیشینه دامنهی جابجایی موج برشی ML در پوستهی ایران بدست آمده است. دادههای استفاده شده در این مطالعه شامل 56152 خوانش سرعتِ ML استخراج شده از شکلموجهای ثبت شده توسط شبکههای لرزهنگاری دائم و موقت ایران است. زلزلههای انتخاب شده شامل 2943 رویداد زلزله در قالب 63 خوشهی لرزها...
