VLA maps of ammonia emission were made for the Galactic Center region. The NH3(1,1) and NH3(2,2) transitions were observed in three 2 ×2 fields covering Sgr A and the region 3 immediately south of it. In the central 3 parsecs surrounding Sgr A we find emission which appears to be associated with the circumnuclear disk (CND), both morphologically and kinematically. This central emission is conne...
OBJECTIVE To assess risk factors for chronic noncommunicable disease (CND) and to identity social inequalities in their distribution among the adult Brazilian population. METHODS Study of CND risk factors (including tobacco use, overweight and obesity, low fruit and vegetable intake (LFVI), insufficient leisure-time physical activity (LTPA), sedentary lifestyle, and alcohol abuse, among other...
We describe an implicit prediction of the accretion disk models constructed by Wardle and Königl (1990) for the circumnuclear disk (CND) of gas and dust near the Galactic center: supersonic ambipolar diffusion, an essential dynamical ingredient of the Wardle-Königl disks, will cause the alignment of dust grains due to a process described by Roberge, Hanany, & Messinger (1995). We calculate synt...
We present high resolution H41 hydrogen recombination line observations of the 1 2 (3 pc) region surrounding Sagittarius A (Sgr A ) at 92 GHz using the Millimeter Array at the Owens Valley Radio Observatory (OVRO) with an angular resolution of 7 3 and velocity resolution of 13 km s−1. New observations of H31 , H35 , H41 and H44 lines were obtained using the NRAO 12-m telescope, and their relati...
Central nodal metastases in papillary thyroid carcinoma based on tumor histologic type and focality.
OBJECTIVE To determine the risk of nodal metastases to the central compartment from differentiated papillary thyroid carcinoma (PTC) relative to known prognostic variables. DESIGN A 7-year single-institutional retrospective review. SETTING Tertiary academic center. PATIENTS A total of 115 patients undergoing central neck dissection (CND) for PTC or follicular variant PTC (FVPTC). MAIN O...
Low-density parity-check (LDPC) codes are very powerful error-correction codes with capabilities approaching the Shannon’s limits. In evaluating the error performance of a LDPC code, the computer simulation time taken becomes a primary concern when tens of millions of noise-corrupted codewords are to be decoded, particularly for codes with very long lengths. In this paper, we propose modeling t...
Context. The Galactic Center black hole and the nuclear star cluster are surrounded by a clumpy ring of gas dust, circumnuclear disk (CND), that rotates about them at standoff distance ≃1.5 pc. mass density individual clumps in CND disputed. Aims. We seek to use H 2 characterize clump size distribution investigate morphology dynamics interface between ionized interior layer molecular reservoir ...
با توجه به افزایش نیاز و تقاضا به مواد غذایی بیشتر و کاهش منابع آبوخاک، حفظ اراضی و ارتقا کمی و کیفی عملکرد گیاهان در واحد سطح با تأمین مواد موردنیاز خاک و گیاه تحقق مییابد. شناسایی وضعیت عنصرهای غذایی در گیاهان، راهکاری مؤثر در تعیین الگوی مصرفی عنصرهای غذایی و افزایش عملکرد و بهبود کیفیت محصولات کشاورزی است. ازاینرو در این پژوهش با استفاده از نتایج شاخصهای DOP، DRIS و CND به تجزیهوتحلیل...
Nodulation is the result of a symbiosis between legumes and rhizobial bacteria in soil. This symbiosis is mutually beneficial, with the bacteria providing a source of nitrogen to the host while the plant supplies carbon to the symbiont. Nodule development is a complex process that is tightly regulated in the host plant cell through networks of gene expression. In order to examine this regulatio...
Abstract Based on a large dataset containing thousands of real-world networks ranging from genetic, protein interaction and metabolic to brain, language, ecology social networks, we search for defining structural measures the different complex network domains (CND). We calculate 208 all using comprehensive scrupulous workflow statistical machine learning methods, investigated limitations possib...
