Three-dimensional light structure of an upland Quercus stand post-tornado disturbance

Composition, structure, and intra-stand spatial patterns along a disturbance severity gradient in a Quercus stand

Woody Regeneration in a Southern Appalachian Quercus Stand Following Wind Disturbance and Salvage Logging

In the eastern United States, the practice of salvage logging is common to reclaim economic losses and/or reduce fuel loading following a natural disturbance. A current hypothesis states that two disturbances in rapid succession (i.e., compounded disturbance) have a cumulative severity of impact and may displace the successional trajectory further than either disturbance occurring separately. O...

Probability current tornado loops in three–dimensional scattering

We consider scattering of a three–dimensional particle on a finite family of δ potentials. For some parameter values the scattering wavenctions exhibit nodal lines in the form of closed loops, which may touch but do not entangle. The corresponding probability current forms vortical singularities around these lines; if the scattered particle is charged, this gives rise to magnetic flux loops. Th...

Thermoelastic Interaction in a Three-Dimensional Layered Sandwich Structure

The present article investigates the thermoelastic interaction in a three-dimensional homogeneous and isotropic sandwich structure using the dual-phase-lag (DPL) model of generalized thermoelasticity. The incorporated resulting non-dimensional coupled equations are applied to a specific problem in which a sandwich layer of unidentical homogeneous and isotropic substances is subjected to time-de...

Evaluation of site impacts associated with three silvicultural prescriptions in an upland hardwood stand in northern Alabama, USA

Soil disturbance patterns and associated changes in soil physical status were measured in a study that evaluated the implementation of three alternative management prescriptions in an upland hardwood stand in northern Alabama, USA. Management prescriptions applied in this study consisted of a clear-cut, strip cut, and deferment cut that were compared to a non-harvested control. Final tabulation...
