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...
The charge-coupled device (CCD) has been developed primarily as a compact image sensor for consumer and industrial markets, but is now also the preeminent visible and ultraviolet wavelength image sensor in many fields of scientific research including space-science and both Earth and planetary remote sensing. Today’s scientific or science-grade CCD will strive to maximise pixel count, focal plan...
in this article a comparative study for modeling and optimization of 2-methylpropane-2-thiol removal from contaminated soil by ultrasound is investigated. central composite design (ccd) and artificial neural network (ann) were utilized and compared to each other in order to obtain appropriate predicting model with respect to sonication power (w), sonication time (min) and water/reactor volume r...
The task of fitting parametric curve models to boundaries of perceptually meaningful image regions is a key problem in computer vision with numerous applications, such as image segmentation, pose estimation, 3-D reconstruction, and object tracking. In this thesis, we propose the Contracting Curve Density (CCD) algorithm and the CCD tracker as solutions to this problem. The CCD algorithm solves ...
Background: Cleidocranial dysplasia (CCD) is a rare inherited skeletal dysplasia, with an incidence of 1 case per 1000,000 individuals. It is a form of predominantly autosomal dominant inheritance and is associated with a mutation in runt related transcription factor-2 gene mapped on chromosome 6p21. This disease primarily affects the bones formed by intramembranous ossification and is characte...
