The Intel Corporation is developing a new parallel software and compiler called Concurrent Collections (CnC) to make programming in parallel easier for the user. CnC provides a system of collections comprised of steps, items, and tags. A CnC user specifies their algorithm in a graph representation using these constructs. Using this graph of dependencies, CnC automatically identifies paralleliza...

PC-based software computer numerical control (CNC) system is the ideal for open CNC system, but there are some problems about the current open CNC system, such as the limitation of interpolation cycle, demanding on high-speed and high precision machining and the limitation of operation system (OS). So advances a novel PC-based architecture for compiled-type software CNC system, in the architect...

در این پژوهش، برای بهبود ویژگی­های کاربردی فیلم­های بر پایه نشاسته، ابتدا از میزان ثابت اسیدسیتریک و پلی­وینیل­الکل (PVOH) استفاده و پس از آن اثر سطوح مختلف غلظت دو نوع نانوذره نانوکریستال ­سلولز (CNC) و دی­اکسید­ تیتانیم (TiO2) به‌صورت توأم و نرم­کننده گلیسرول (GLY) بررسی شد.  آزمون گرماسنجی پویشی افتراقی (DSC) نشان می­دهد که افزودن CNC و TiO2 به‌ترتیب موجب افزایش دمای ذوب و انتقال شیشه­ای و ک...

A charge neutral complex (CNC) was formed in aqueous solution by combining an orange light emitting anionic conjugated polyelectrolyte and a saturated cationic polyelectrolyte at a 1:1 ratio (per repeat unit). Photoluminescence (PL) from the CNC can be quenched by both the negatively charged dinitrophenol (DNP) derivative, (DNP-BS(-)), and positively charged methyl viologen (MV(2+)). Use of the...

This paper aims to examine the effect of cellulose nanocrystals (CNC) on the hydration, transport behavior, and microstructure of cement mixtures. The addition of CNC delayed hydration at an early age but improved hydration at later ages. A small increase in the electrical resistivity of the cement mixtures with CNC was observed. Statistical nanoindentation showed a small tendency to a larger v...

Carney complex (CNC) is a familial multiple neoplasia and lentiginosis syndrome (OMIM 160980, http://www.ncbi.nlm.nih.gov/omim) with features overlapping those of other multiple endocrine neoplasias and hamartomatoses, Peutz-Jeghers syndrome (PJS) in particular. Although a number of patients with CNC and ovarian tumors have been described in individual patient reports, it is unclear whether ova...

Plasma calcitonin (CT) was measured in the basal state and/or during provocative tests of hormone secretion in 11 children with congenital non-goitrous cretinism (CNC), in 1 girl with a lingual thyroid, and in 11 normal children. Basal and stimulated CT concentrations were significantly lower in the patients with CNC than in the normal subjects. Mean basal CT (+/- SE) was 41 +/- 4 pg/ml in the ...

Cardiac neural crest (CNC) plays a requisite role during cardiovascular development and defects in the formation of CNC-derived structures underlie several common forms of human congenital birth defects. Migration of the CNC cells to their destinations as well as expansion and maintenance of these cells are important for the normal development of the cardiac outflow tract and aortic arch arteri...

Preliminary communication There are currently no appropriate methods to find CNC system software defects and eliminate hidden dangers. In order to improve CNC system reliability, the architecture expansion-based fault location method in CNC system software was proposed in this paper. The failure of CNC system software was 619 analysed, the expansion method of CNC system software architecture wa...

The complex of myxomas, spotty skin pigmentation and endocrine overactivity, or Carney complex (CNC), is a familial multiple endocrine neoplasia and lentiginosis syndrome. CNC is inherited in an autosomal dominant manner and is genetically heterogeneous. Its features overlap those of McCune-Albright syndrome and other multiple endocrine neoplasia (MEN) syndromes. Spotty skin pigmentation is the...
