The proposed stimulus design for linearity test is embedded in a differential successive approximation register analog-to-digital converter (SAR ADC), i.e. a design for testability (DFT). The proposed DFT is compatible to the pattern generator (PG) and output response analyzer (ORA) with the cost of 12.4-% area of the SAR ADC. The 10-bit SAR ADC prototype is verified in a 0.18-μm CMOS technolog...

Introduction: The aim of present study was to assess the correlation between glucose and lipid biomarkers variations with biometric characteristics and intraocular pressure changes following Ramadan fasting. Methods: A total of 100 healthy fasting volunteers were enrolled in the study. Of them, 89 subjects completed the study with respect to inclusion and exclusion criteria. Right eye ocular ax...

The patient presented herein is a 52-year-old woman suffering from primary open angle glaucoma (POAG) in both eyes. She has no history of systemic disorders and is not on any systemic medications. She underwent laser in situ keratomileusis (LASIK) 9 years ago for refractive error of -5.50-3.00×180 in both eyes, and was diagnosed with glaucoma 7 years afterwards. Her ocular examination when I sa...

We present the SQL Performance Analyzer, a novel approach in Oracle Database 11g to testing database changes, such as upgrades, parameter changes, schema changes, and gathering optimizer statistics. The SQL Performance Analyzer offers a comprehensive solution to enable users to forecast and analyze how a system change will impact SQL query plans and run time performance, so they can tune their ...

Trachoma, the world's leading cause of preventable blindness, is produced by chronic ocular infection with Chlamydia trachomatis, an obligate intracellular bacterium. While many studies have focused on immune mechanisms for trachoma during chronic stages of infection, less research has targeted immune mechanisms in primary ocular infections, events that could impact chronic responses. The goal ...

Atopic diseases which include bronchial asthma, allergic rhinitis, atopic dermatitis, and ocular allergic disorders are among the most frequent conditions experienced by patients. Allergic conjunctivitis, an atopic ocular disease, is one of the most common problems encountered in general ophthalmic practice and the only ocular inflammatory disease that represents a pure type-I hypersensitivity ...

Brief monocular deprivation (< or =3 d) induces a rapid shift in the ocular dominance of binocular neurons in the juvenile rodent visual cortex but is ineffective in adults. Here, we report that persistent, rapid, juvenile-like ocular dominance plasticity can be reactivated in adult rodent visual cortex when monocular deprivation is preceded by visual deprivation. Ocular dominance shifts in vis...

We developed a chemiluminescent ozone analyzer and constructed an ozone bolus generator with the eventual goal of using a bolus-response method to measure noninvasively the longitudinal distribution of ozone absorption in human lungs. Because the analyzer will be used to sample gases within a single breath, it must have a sufficiently rapid response to monitor changes in ozone concentration dur...

Involuntary ocular tracking responses to background motion offer a window on the dynamics of motion computations. In contrast to spatial attention, we know little about the role of feature-based attention in determining this ocular response. To probe feature-based effects of background motion on involuntary eye movements, we presented human observers with a balanced background perturbation. Two...
