The phylogenetic relationships among seven Callosciurus species from the Indochina Peninsula, including C. honkhoaiensis which is endemic to Hon Khoai Island, were studied using complete mitochondrial cytochrome b gene sequences (1140 bases). We primarily focused on position of pygerythrus, distributed in western part peninsula. identified two main lineages: 1) caniceps, honkhoaiensis, inornatu...
حفاری‌های باستان‌شناسی هیئت ایرانی'ایتالیایی در محوطۀ تل آجری، در سال 1390 شروع شد و بقایای معماری مزّین به آجرهای لعاب‌دار بسیار نفیسی از این منطقه بهدست آمد که مشابهت‌های قابلملاحظهای با آجرهای ایلامی و هخامنشی یافته شده در تختجمشید و شوش دارد. آجرهای مکشوفه، یا در ساختار معماری استفاده شده و یا به صورت دستنخورده در محل حفاری حفظ شده‌اند. شناسایی مواد بهکار رفته در ساخت این آجرها، لعاب، ...
محافظهکاری، تمایل حسابداران به الزام درجۀ بالاتری از تأییدپذیری برای شناسایی اخبار خوشایند در مقایسه با اخبار ناخوشایند، معنا شده است. این مقاله براساس الگوی بال، کوتاری و والری (2013) به بررسی وجود محافظهکاری شرطی در سود گزارششدۀ شرکتهای پذیرفتهشده در بورس اوراق بهادار تهران پرداخته است. این الگو با استفاده از متغیرهای مالی اندازه، نسبت ارزش دفتری به ارزش بازار حقوق صاحبان سهام، اهرم، نوس...
A comprehensive thermochemical database is constructed based on high–throughput first-principles phonon calculations of over 3000 atomic structures in limited concentrations Ni, Fe, and Co alloys involving a total 26 elements including Al, B, C, Cr, Cu, Hf, La, Mn, Mo, N, Nb, O, P, Re, Ru, S, Si, Ta, Ti, V, W, Y, Zr, providing data largely unavailable from existing experiments. The can be emplo...
Investment-based asset pricing uses the link between stock and investment returns to tie expected returns with firm characteristics. I derive the equivalence between these two returns in the Q-framework with variable capacity utilization, proportional operating costs, irreversible investment, and dividend constraints. With multiple capital goods, stock return is the value-weighted average of in...
Substance abuse counselors are critical as the key arbiters of clients' acceptance and use of innovative treatment techniques, with their potential support embedded in their knowledge of and attitudes towards particular innovations. In this analysis the authors examine the role of substance abuse counselors in the adoption of a psychosocial treatment innovation, contingency management (CM). Usi...
An 11 year old boy with cystic fibrosis suffered a stroke, producing right sided weakness. Four years previously a totally implantable venous access device (Port-aCath) had been inserted. Magnetic resonance angiography revealed a filling defect in the left middle cerebral artery. Transoesophageal echocardiography demonstrated a thrombus attached to the tip of the Port-a-Cath and also the presen...
Space competition between corals and seaweeds is an important ecological process underlying coral-reef dynamics. Processes promoting seaweed growth and survival, such as herbivore overfishing and eutrophication, can lead to local reef degradation. Here, we present the case that increasing concentrations of atmospheric CO(2) may be an additional process driving a shift from corals to seaweeds on...
BACKGROUND Myelin transcription factor 1-like (MYT1L) is a member of the myelin transcription factor 1 (MYT1) gene family, and the neural specific, zinc-finger-containing, DNA-binding protein that it encodes plays a role in the development of the nervous system. On the basis of a recent copy number variation (CNV) study showing that this gene is disrupted in mental disorder patients, we investi...
