Sensitivity of Infiltration Models in Rural Soils Overlying Unsteady Shallow Groundwater

open access: yesIraqi Geological Journal, 2023
According to the theoretical concept, the infiltration rate gradually decreases as the shallow groundwater rises to the surface of unsaturated soil regardless of the hydraulic conductivity value.

A finite element analysis of a silicon based double quantum dot structure [PDF]

open access: yes, 2006
We present the results of a finite-element solution of the Laplace equation for the silicon-based trench-isolated double quantum-dot and the capacitively-coupled single-electron transistor device architecture.

Root Regrowth and Discoloration in <em>Quercus virginiana</em> Mill. Following Linear Trenching

open access: yes, 2023
Background: As long-lived organisms, urban trees often encounter development and redevelopment activities in close proximity during their lifespans. These activities can damage tree roots, often through methods like root severing during trenching or excavation. Methods: In 2017, we simulated trenching damage on mature Quercus virginiana Mill.

Effectiveness of physical barriers in mitigating human–elephant negative interactions in North-East India

open access: yesFrontiers in Conservation Science, 2022
Physical barriers, like solar fences, elephant-proof trenches, stone, or rubble walls, are installed as conflict mitigation interventions in India’s major Asian elephant (Elephas maximus) ranges.

The role of elasticity in slab bending [PDF]

open access: yes, 2014
International audiencePrevious studies showed that plate rheology exerts a dominant control on the shape and velocity of subducting plates. Here, we perform a systematic investigation of the role of elasticity in slab bending, using fully dynamic 2-D ...

Analysis of pn Junction Deep Trench Isolation with SU-8/SiO2-Liner Passivation in a Linear Butt-Coupled 3D CMOS Si Photodetector Array [PDF]

open access: yesProceedings of Eurosensors 2017, Paris, France, 3&ndash;6 September 2017, 2017
The realization of 30 µm-deep trench isolation in a linear array of butt-coupled 3D CMOS silicon photodetectors is investigated by implementing the formation of a shallow n+-p junction and SiO2-liner over the trench sidewalls as well as the SU-8 filling trenches for passivation.

On the energetic origin of self-limiting trenches formed around Ge/Si quantum dots

open access: yes, 2004
At high growth temperatures, the misfit strain at the boundary of Ge quantum dots on Si(001) is relieved by formation of trenches around the base of the islands.
