High-Speed Fully Differential Two-Step ADC Design Method for CMOS Image Sensor

open access: yesSensors, 2023
The application requirements of high frame rate CMOS image sensors (CIS) in the industry have not been satisfied due to the speed limitations in traditional single-slope and serial two-step analog-to-digital converters (ADCs). In this paper, a high-speed

On the issue of numerical transformation of seismological signal

open access: yesГеофизический журнал, 2012
This article is devoted to conversion of seismic analog signal to digital code. The conversion is done by means of microprocessor instead of digital signal processor. This makes the data handling cheaper retaining its efficiency.

Early Body Mass Index z‐Score Change and Resolution of Severe Malnutrition in Children With Sickle Cell Anemia in a Low‐Income Setting: A Prospective Single‐Arm Extension Study

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Children with sickle cell anemia (SCA) in low‐income settings are at risk of severe malnutrition, but optimal nutritional management has not been established. We evaluated an intensified ready‐to‐use therapeutic food (RUTF) regimen in children with persistent severe malnutrition after initial treatment and assessed whether early ...

Dickson-Charge-Pump-Based Voltage-to-Time Conversion for Time-Based ADCs in 28-nm CMOS

open access: yesIEEE Open Journal of Circuits and Systems, 2021
This article demonstrates a digitally friendly time-based analog-to-digital converter (ADC) exploiting Dickson charge-pump (CP) as part of a voltage-to-time conversion (VTC) implemented in 28-nm CMOS. In the proposed technique, the Dickson CP generates a

Exercise Capacity, Physical Activity, Fatigue, and Neurocognitive Function in Adult Survivors of Childhood Acute Lymphoblastic Leukemia

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Adult survivors of childhood acute lymphoblastic leukemia (ALL) are at risk of reduced exercise capacity, decreased physical activity levels, persistent fatigue, and neurocognitive deficits. The aim was to investigate exercise capacity and physical activity levels of adult survivors of childhood ALL and their associations with ...

Spatial and single‐nuclei transcriptomics reveals idiosyncratic and generic patterns in papillary and anaplastic thyroid cancers

open access: yesMolecular Oncology, EarlyView.
Matched spatial transcriptomics and single‐nuclei RNA‐seq were generated for anaplastic and BRAFV600E papillary thyroid cancers revealing generic and tumor‐specific states occurring in cancer cells and in the tumor microenvironment. In this context, cancer dedifferentiation mirrored organoid maturation through ordered thyroid marker gain/loss ...
