Study of dark current random telegraph signal in proton-irradiated backside illuminated CMOS image sensors

Results in Physics, 2020
The dark current random telegraph signal (DC-RTS) has been investigated in a four-transistor pinned photodiode 0.18-μm backside illuminated CMOS image sensor (BSI CIS). The sensors were irradiated by high energy protons of 50, 60 and 70 MeV, respectively.

“Alien versus predator”: predatory effect of coccinellid Exochomus quadripustulatus on the scale insect Toumeyella parvicornis. An open‐field experimentation on the Pinus pinea of Rome

Insect Science, EarlyView.
The release of gravid Exochomus quadripustulatus females proved to be effective in containing Toumeyella parvicornis infestations on stone pine trees, under open‐field condition. The ladybugs caused a lower infestation level compared to the trees that did not receive any ladybugs during the observation season.

Pig Seminal Plasma Extracellular Vesicles Enhance Motility During Preservation of Epididymal Spermatozoa but Impair Capacitation and IVF Parameters

Andrology, EarlyView.
ABSTRACT Background Extracellular vesicles (EVs) produced by accessory sex glands play a key role in sperm functionality, influencing motility, viability, acrosome integrity, metabolic activity, and capacitation. Most studies on the effects of EVs on spermatozoa have focused on ejaculated spermatozoa, which have already been exposed to their own native

GravityCam: higher resolution visible wide-field imaging [PDF]

, 2018
The limits to the angular resolution has, during the latest 70 years, been obtainable from the ground only through extremely expensive adaptive optics facilities at large telescopes, and covering extremely small spatial areas per exposure.

Surveillance patterns in non‐muscle‐invasive bladder cancer across risk groups: a real‐world analysis

BJU International, EarlyView.
Objective To provide insight into real‐world surveillance practices for patients with low‐risk (LR), intermediate‐risk (IR), and (very) high‐risk (HR) non‐muscle invasive bladder cancer (NMIBC). Patients and Methods Cystoscopy surveillance patterns were analysed using real‐world data from two population‐based cohort studies in the Netherlands ...

A High Speed CMOS Image Sensor with a Novel Digital Correlated Double Sampling and a Differential Difference Amplifier

Sensors, 2015
In order to increase the operating speed of a CMOS image sensor (CIS), a new technique of digital correlated double sampling (CDS) is described. In general, the fixed pattern noise (FPN) of a CIS has been reduced with the subtraction algorithm between ...
