Cleidocranial dysplasia (CCD) is an autosomal dominant, generalized skeletal dysplasia in humans that has been mapped to the short arm of chromosome 6. We report linkage of a CCD mutation to 6p21 in a large family and exclude the bone morphogenetic protein 6 gene (BMP6) as a candidate for the disease by cytogenetic localization and genetic recombination. CCD was linked with a maximal two-point ...

We discuss diagrammatic modifications to the coupled cluster doubles (CCD) equations, wherein different groups of terms out of rings, ladders, crossed-rings, and mosaics can be removed to form approximations to the coupled cluster method, of interest due to their similarity with various types of random phase approximations. The finite uniform electron gas (UEG) is benchmarked for 14- and 54-ele...

Colony collapse disorder (CCD) is a mysterious disappearance of honey bees that has beset beekeepers in the United States since late 2006. Pathogens and other environmental stresses, including pesticides, have been linked to CCD, but a causal relationship has not yet been demonstrated. Because the gut acts as a primary interface between the honey bee and its environment as a site of entry for p...

We investigated the effects of chronic compression (CCD) of the L3 and L4 dorsal root ganglion (DRG) on pain behavior in the mouse and on the electrophysiological properties of the small-diameter neuronal cell bodies in the intact ganglion. CCD is a model of human radicular pain produced by intraforaminal stenosis and other disorders affecting the DRG, spinal nerve, or root. On days 1, 3, 5, an...

BACKGROUND Over the last two winters, there have been large-scale, unexplained losses of managed honey bee (Apis mellifera L.) colonies in the United States. In the absence of a known cause, this syndrome was named Colony Collapse Disorder (CCD) because the main trait was a rapid loss of adult worker bees. We initiated a descriptive epizootiological study in order to better characterize CCD and...

When solving the control co-design (CCD) problem using simultaneous strategy in a deterministic manner, uncertainty stemming from stochastic design variables is ignored, and might have negative influence on performance of dynamic system. In attempting to overcome undesirable effect uncertainty, this research investigates reliability-based (RB-CCD) presents single-loop framework for RB-CCD based...

سیستم خواندن CCD(Charged Coupled Device Read-Out System)دوربین ماهواره‌ها، نیازمند نسبت سیگنال به نویز بالایی است. علت این مسئله،وجود نویزهای خاص و اجتناب‌ناپذیر محموله تصویربرداری فضایی است. این نویزها شامل نویزهای CCD، نویزهایماهواره مانند عدم پایداری کامل ماهواره و نویزهای محیطی مانند تداخل اتمسفر، ذرات باردار، حرکت زمین و ماهواره نسبت به هم، و تداخل‌های الکترومغناطیس است. نویزهای CCDبه دلیل...

BACKGROUND AND PURPOSE Arterial spin-labeling (ASL) was recently introduced as a noninvasive method to evaluate cerebral hemodynamics. The purposes of this study were to assess the ability of ASL imaging to detect crossed cerebellar diaschisis (CCD) in patients with their first unilateral supratentorial hyperacute stroke and to identify imaging or clinical factors significantly associated with ...

BACKGROUND Canine cognitive dysfunction (CCD) is an age-dependent neurodegenerative condition dominated by changes in behavioral patterns. Cohort studies investigating cognitive status in dogs are lacking. OBJECTIVES To investigate cognitive function, progression of age-related behavioral changes, survival, and possible biomarkers of CCD in aged dogs. ANIMALS Fifty-one dogs >8 years old; 21...
