A 75-ps Gated CMOS Image Sensor with Low Parasitic Light Sensitivity [PDF]

Sensors, 2016
In this study, a 40 × 48 pixel global shutter complementary metal-oxide-semiconductor (CMOS) image sensor with an adjustable shutter time as low as 75 ps was implemented using a 0.5-μm mixed-signal CMOS process.

Development of Low Parasitic Light Sensitivity and Low Dark Current 2.8 μm Global Shutter Pixel [PDF]

Sensors, 2018
: We developed a low parasitic light sensitivity (PLS) and low dark current 2.8 μm global shutter pixel. We propose a new inner lens design concept to realize both low PLS and high quantum efficiency (QE).

Charge-Domain Type 2.2 µm BSI Global Shutter Pixel with Dual-Depth DTI Produced by Thick-Film Epitaxial Process [PDF]

Sensors
We developed a 2.2 µm backside-illuminated (BSI) global shutter (GS) pixel featuring true charge-domain-correlated double sampling (CDS). To enhance the inverse parasitic light sensitivity (1/PLS), we implemented a thick-film epitaxial process ...

Prevalence and determinants of intestinal parasitic infections among prison inmates in Central Ethiopia [PDF]

Tropical Diseases, Travel Medicine and Vaccines
Introduction Intestinal parasite infections (IPIs) remain a significant public health concern, particularly in developing countries, where they disproportionately affect vulnerable populations such as prison inmates.

Validation of Digital Slide Scanning and a Convolutional Neural Network for the Detection of Intestinal Parasites in Human Stool Samples [PDF]

Diagnostics
Background: Recent studies have shown that digital microscopy (DM) combined with a convolutional neural network (CNN) model is a valid approach for detecting intestinal protozoa and helminth ova or larvae in both trichrome-stained and wet-mount stool ...

A first attempt at determining the antibody-specific pattern of Platynosomum fastosum crude antigen and identification of immunoreactive proteins for immunodiagnosis of feline platynosomiasis [PDF]

Veterinary World, 2022
Background and Aim: Feline platynosomiasis, also known as lizard poisoning, is a feline hepatic disease caused by the parasitic trematode Platynosomum fastosum. Since this helminth resides in biliary ducts and gallbladder, the heavy infection can lead to

Detection and correction of image distortions induced by parasitic light sensitivity using deep learning methods

Fifteenth International Conference on Machine Vision (ICMV 2022), 2023
Images captured by mobile camera systems are subject to distortions that can be irreversible. Sources of these distortions vary and can be attributed to sensor imperfections, lens defects, or shutter inefficiency. One form of image distortion is associated with high Parasitic-Light-Sensitivity (PLS) in CMOS Image Sensors when combined with Global ...

Gastrointestinal parasitosis diagnosed by colonoscopy as cause of weight loss in 46-year-old woman with three negative stool tests for presence of parasites

Annales Academiae Medicae Silesiensis, 2023
Parasitic infections of the digestive tract remain an important health problem on a global scale. The current epidemiological situation in Poland is unknown because most parasitic diseases, including all caused by helminths, are not subject to reporting.

Predicted visual sensitivity for short-wavelength light in the brood parasitic cuckoos of New Zealand [PDF]

CHINESE BIRDS, 2012
Different lineages of birds show varying sensitivity to light in the ultraviolet (UV) wavelengths. In several avian brood parasite-host systems, UV-reflectance of the parasite eggs is important in discriminating own from foreign eggs by the hosts. In turn, for parasitic females it may be beneficial to lay eggs into host clutches where eggs more closely

Mini-FLOTAC, an Innovative Direct Diagnostic Technique for Intestinal Parasitic Infections: Experience from the Field. [PDF]

, 2013
Soil-transmitted helminths and intestinal protozoa infection are widespread in developing countries, yet an accurate diagnosis is rarely performed.
