Building upon previous work that examined the dynamics and model sensitivity of cyclic mesocyclogenesis, this study uses idealized numerical simulations to investigate the cyclic redevelopment of vertical vortices in ...

The Gulf of Mexico (GoM) is home to more than 50,000 oil and gas wells with approximately 30,000 wells that are plugged and abandoned leading to concerns of oil and gas leakage where currently, little to no monitoring is ...

The filling process of injection molding in various planar gaps and center-gated disks are analyzed numerically. Comprehensive mathematical models are developed for flows in planar gaps and center-gated disks. An incompressible ...

Due to complex sedimentation environment, shale formations are usually characterized as highly heterogeneous and anisotropic in in-situ stresses. The injection process for reservoir stimulation changes the local in-situ ...

The ability to learn is often a desirable property of intelligent systems which can make them more adaptive. However, it is difficult to develop sophisticated learning algorithms that are effective. One approach to the ...

Rural places and schools are diverse, presenting challenges for teaching and for understanding the needs of rural teachers. The recent NCES Report on Status of Education in Rural America indicates "no measurable differences" ...

Understanding individual nutritional requirements can generate good predictions for how communities should be structured and how ecosystems function over gradients of nutrient availability. Aboveground consumers can shape ...

Escherichia coli is a single species consisting of many biotypes, some of which are commensal colonizers of mammals and others that cause disease. Humans are colonized on average with five commensal biotypes, and it is ...
