Fire as an interactive component of dynamic vegetation models (2008)

Vivek K. Arora, George J. Boer

[1] Fire affects ecosystems by altering both their structure and the cycling of carbon and nutrients. The emissions from fires represent an important biogeochemical pathway by which the biosphere...

Moisture processing at the land surface in CCCma AGCM3 (2007)

Vivek K. Arora, George J. Boer

Precipitation is intercepted, and moisture is stored and exchanged between three land-surface moisture reservoirs, namely the ground, the snow, and the canopy. The role that these moisture reservoirs...

Simulating competition and coexistence between plant functional types in a dynamic vegetation model. Earth Interact., submitted for publication (2005)

Vivek K. Arora, George J. Boer

ABSTRACT: The global distribution of vegetation is broadly determined by climate, and where bioclimatic parameters are favorable for several plant functional types (PFTs), by the competition between...

The Temporal Variability of Soil Moisture and Surface Hydrological Quantities in a Climate Model (2005)

Vivek K. Arora, J. Boer

The variance budget of land surface hydrological quantities is analyzed in the second Atmospheric Model Intercomparison Project (AMIP2) simulation made with the Canadian Centre for Climate Modelling...

Vivek K. Arora, George J. Boer

ABSTRACT: Root distribution is treated as a static component in most current dynamic vegetation models (DVMs). While changes in leaf and stem biomass are reflected in leaf area index (LAI) and...

Implementation of a large-scale variable velocity flow routing algorithm in the Canadian Regional Climate Model (CRCM (2003)

Vivek K. Arora, Daniel Caya, René Laprise

ABSTRACT Implementation and validation of a flow routing scheme for the North American domain of the Canadian Regional Climate Model (CRCM) is described. A variable velocity flow routing algorithm is...

Lentivirus Nef Specifically Activates Pak2

Arora, Vivek K., Molina, Rene P., Foster, John L., Blakemore, John L., Chernoff, Jonathan, Fredericksen, Brenda L., ...

Nef proteins from human immunodeficiency virus type 1 (HIV-1) and simian immunodeficiency virus (SIV) have been found to associate with an active cellular serine/threonine kinase designated...

Genetic and Functional Diversity of Human Immunodeficiency Virus Type 1 Subtype B Nef Primary Isolates

Foster, John L., Molina, Rene P., Luo, Tianci, Arora, Vivek K., Huang, Yaoxing, Ho, David D., ...

We have characterized the functional integrity of seven primary Nef isolates: five from a long-term nonprogressing human immunodeficiency virus (HIV)-infected individual and one each from two...

Activation of p21-Activated Kinase 2 by Human Immunodeficiency Virus Type 1 Nef Induces Merlin Phosphorylation

Wei, Bangdong L., Arora, Vivek K., Raney, Alexa, Kuo, Lillian S., Xiao, Guang-Hui, O'Neill, Eduardo, ...

The accessory human immunodeficiency virus type 1 (HIV-1) protein Nef activates the autophosphorylation activity of p21-activated kinase 2 (PAK2). Merlin, a cellular substrate of PAK2, is homologous...
