HGV: the identification, biology and prevalence of an orphan virus

Liver, 1998
ABSTRACT— Hepatitis G virus (HGV) and GB virus C (GBV‐C) (both hereinafter referred to as HGV) were independently identified in patients with hepatitis of unknown aetiology. HGV is a positive‐sense RNA virus of the family Flaviviridae. The virus can establish both acute and chronic infection and appears to be sensitive to interferon.

Sweetpotato Insects: Identification, Biology and Management

2009
Sweetpotato, Ipomoea batatas originated in northwestern South America around 8000–6000 Bc (Austin, 1988). Sweetpotato ranks seventh among all food crops worldwide, with an annual production of 115 million MT (FAO, 1980). Approximately 92% of the world’s sweetpotato is produced in Asia and the Pacific islands; 89% is grown in China.

Systems Biology: Identifiability analysis and parameter identification via systems-biology informed neural networks

Methods in molecular biology, 2022
The dynamics of systems biological processes are usually modeled by a system of ordinary differential equations (ODEs) with many unknown parameters that need to be inferred from noisy and sparse measurements.

Systems identification in biology

Transactions of the Institute of Measurement and Control, 1982
The nature of system identification in biological systems is analysed, in order to show what are the special features of biological systems in relation to the identification process, and to reveal what general lessons for measurement and control can be learned from the quantitative study of biological systems.

Identification of parameters in systems biology

Mathematical Biosciences, 2018
We consider the inverse problem for the identification of the finite dimensional set of parameters for systems of nonlinear ordinary differential equations (ODEs) arising in systems biology. A numerical method which combines Bellman's quasilinearization with sensitivity analysis and Tikhonov's regularization is implemented.
