Cancer cell(s) cycle sequencing reveals universal mechanisms of apoptosis
2010
In this paper, cell cycle in higher eukaryotes and their molecular networks signals both in G 1/S and G2/M transitions are replicated in silico. Biochemical kinetics, converted into a set of differential equations, and system control theory are employed to design multi-nested digital layers to simulate protein-to-protein activation and inhibition for cell cycle dynamics in the presence of damaged genomes. Sequencing and controlling the digital process of four micro-scale species networks (p53/Mdm2/DNA damage, p21mRNA/cyclin-CDK complex, CDK/CDC25/wee1/ SKP2/APC/CKI and apoptosis target genes system) not only allows the comprehension of the mechanisms of these molecule interactions but paves…
Digitalisation of municipal healthcare collaboration with volunteers: a case study applying normalization process theory
2021
Abstract Background Increasing use of volunteers in healthcare requires structured collaboration between healthcare services and volunteers. The aim of this research was to explore critical issues and strategies in the implementation process of a digital solution for collaboration with and coordination of volunteers in municipal healthcare services. Methods Qualitative data collection was used to study implementation of a digital system for collaboration with volunteers in three Norwegian municipalities. Three rounds of interviews were conducted with healthcare employees from a volunteer centre and from municipality healthcare units in three municipalities: before implementation, and 6 and …

An Electronic Emulator of Combined Photovoltaic and Solar Thermal Systems
2010
An emulator of combined Photovoltaic and Solar Thermal (CPS) systems is presented. In order to carry out early testing on the design of such systems, a - microcontrolled based - hardware board has been designed, implemented and tested. This emulator is able run several typical daily solar irradiation patterns as a function of the seasons and a complete solar thermal and photovoltaic model that depends on a very flexible set of parameters characterizing the real CPS behaviour. By properly varying these parameters many different CPS models can easily be created and tailored to the energy performance needed for a predefined target application. Beside these functionalities, the CPS emulator is …
