Formation of optimal Boolean functions for analog-digital conversion [PDF]

open access: yes2017 25th Telecommunication Forum (TELFOR), 2017
This paper describes a situation in which the function obtained from an analog-to-digital conversion is considered a partially-certain function. In this case it is possible to neglect the least significant bits and therefore redefine them arbitrarily. A realization of proposed method simplifies the further processing of the received signal, and saves ...

Doubling-resolution analog-to-digital conversion based on PIC18F45K80

open access: yesThe Journal of Engineering, 2014
Aiming at the analog signal being converted into the digital with a higher precision, a method to improve the analog-to-digital converter (ADC) resolution is proposed and described. Based on the microcomputer PIC18F45K80 in which the internal ADC modules

Analog Convolutional Operator Circuit for Low-Power Mixed-Signal CNN Processing Chip

open access: yesSensors, 2023
In this paper, we propose a compact and low-power mixed-signal approach to implementing convolutional operators that are often responsible for most of the chip area and power consumption of Convolutional Neural Network (CNN) processing chips.

European Standard Clinical Practice Guideline and EXPeRT Recommendations for the Diagnosis and Management of Gastroenteropancreatic Neuroendocrine Neoplasms in Children and Adolescents

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...

Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM

open access: yesFEBS Letters, EarlyView.
Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.
