In a coastal, fog-influenced forest on Santa Cruz Island in southern California, we
observed mortality of Bishop pine (Pinus muricata D.Don) trees following a brief (2 year), yet
intense, drought. While anecdotal evidence indicates that drought-induced Bishop pine mortality
has occurred in the past in the stand we studied, this...
The nucleocapsid protein (N protein) of the severe acute respiratory syndrome coronavirus 2 is known to play an essential part of the virus’ functions. The N protein can protect and package the large 29,903 nucleotide genomic RNA whilst also interacting with structural membrane protein M and the spike protein S....
The myriad of problems facing the world today are increasingly complex, dynamic, and transcend multiple domains necessitating the need for an equally complex and trans-disciplinary approach to solve these problems. Systems thinking promises to provide the skills necessary for all citizens of the world, not just the experts, to handle...
This thesis is on the existence and uniqueness of weak solutions to the Navier-Stokes equations in R3 which govern the velocity of incompressible fluid with viscosity ν. The solution is obtained in the space of tempered distributions on R3 given an initial condition and forcing data which are dominated by...
Identifying coherent sub-graphs in networks is important
in many applications. In power systems, large systems
are divided into areas and zones to aid in planning and control
applications. But not every partitioning is equally good for
all applications; different applications have different goals, or
attributes, against which solutions should be...
We sampled boles, branches, and roots of four Douglas-fir (Pseudotsuga menziesii var. menziesii) trees to learn a) whether branches and roots have a zone of juvenile wood, defined as a zone with progressive changes in wood density and/or tracheid length from the pith outward at successively greater cambial
ages, and...
Summertime wind stress along the coast of the northwestern United States typically exhibits intraseasonal oscillations (ISOs) with periods from ≈15 to 40 days, as well as fluctuations on the 2- to 6-day “weather-band” and 1-day diurnal time scales. Coastal upwelling of cool, nutrient-rich water is driven by extended periods of...

Dendritic ecological networks (DENs) are a unique form of ecological networks that exhibit a dendritic network topology (e.g. stream and cave networks or plant architecture). DENs have a dual spatial representation; as points within the network and as points in geographical space. Consequently, some analytical methods used to quantify relationships...
