乙型肝炎病毒 病毒性疾病 蛋白酶 核传感器
2022/9/15
新发和反复爆发的病毒性疾病是一个严重的公共卫生问题。历史上,乙型肝炎病毒 (HBV) 已夺去数百万人的生命。目前,COVID-19大流行已造成巨大的经济损失和数百万人死亡。乙型肝炎是一种慢性病毒性疾病,其主要挑战是消除HBV共价闭合环状DNA (cccDNA),减少乙型肝炎表面抗原 (HBsAg)。

Process Oriented Calibration Scheme HBV Hydrological Model
2009/10/26
A process oriented calibration scheme (POC), developed for the HBV hydrological
model is presented. Twelve parameters were calibrated in two steps.
Firstly, initial parameter estimates were made fro...
A Simple Automatic Calibration Routine for the HBV Model
Automatic Calibration Routine HBV Model
2009/10/23
A simple, but efficient, method for automatic calibration of the conceptual HBV
rainfall-runoff model was developed. A new criterion, which combines the com-
monly used efficiency criterion R 2 and ...
Estimation of Parameter Uncertainty in the HBV Model
Estimation of Parameter Uncertainty HBV Model
2009/10/23
Usually the HBV model is calibrated by seeking one optimal parameter set that
represents the catchment. From experience we know, however, that it is hardly
poss~ble to find an unique parameter set. ...

Priestley-Taylor Evapotranspiration HBV-Simulations
2009/10/23
Estimations of potential evapotranspiration as input to runoff calculations with
the HBV model are usually given as monthly standard values calculated with the
Penman method. Daily changes in the we...
