Analytical and numerical modeling of shallow water flow in a channel: Theoretical approaches and simulations

International Journal of Applied Mechanics and Engineering
This study focuses on the modeling and simulation of shallow water flows in a channel through the application of the Saint-Venant equations. Two main approaches were explored: an analytical solution and a numerical method based on finite difference ...

Effects of water depth and sediment nutrients on Vallisneria spinulosa in Lake Poyang

Journal of Freshwater Ecology, 2019
Poyang Lake, the largest freshwater lake in China, has experienced a large decrease in wetland area due to long-term overutilization and especially after the hydrological drought events from 2003. This outdoor study was conducted to elucidate the impacts

Spatio-temporal distribution of Diaphanosoma brachyurum (Cladocera: Sididae) in freshwater reservoir ecosystems: importance of maximum water depth and macrophyte beds for avoidance of fish predation

Journal of Limnology, 2014
In empirical studies, Cladocera is commonly utilized as a primary food source for predators such as fish, thus, predator avoidance are important strategies to sustain their population in freshwater ecosystems. In this study, we tested the hypothesis that

Transcriptional network analysis of PTEN‐protein‐deficient prostate tumors reveals robust stromal reprogramming and signs of senescent paracrine communication

Molecular Oncology, EarlyView.
Combining PTEN protein assessment and transcriptomic profiling of prostate tumors, we uncovered a network enriched in senescence and extracellular matrix (ECM) programs associated with PTEN loss and conserved in a mouse model. We show that PTEN‐deficient cells trigger paracrine remodeling of the surrounding stroma and this information could help ...

Habitat Features Influencing Waterbird Use of Managed Wetlands Enrolled in a Public‐Private Partnership for Land Conservation: The California Waterfowl Habitat Program

Ecology and Evolution
Draining, water diversion, and development have greatly reduced the availability of freshwater wetland habitat around the world, and many remaining wetlands are on private lands. Public–private partnership programs can be an important means for promoting

Water depth and feed pellet type effects on growth and feed utilization in the rearing of green turtle (Chelonia mydas Linnaeus, 1758)

Aquatic Living Resources, 2017
The rearing of green turtles (Chelonia mydas Linnaeus, 1758) before their release to natural habitats has been practiced in several countries, whereas little information is available for inferring optimal husbandry protocols.

PARP inhibition and pharmacological ascorbate demonstrate synergy in castration‐resistant prostate cancer

Molecular Oncology, EarlyView.
Pharmacologic ascorbate (vitamin C) increases ROS, disrupts cellular metabolism, and induces DNA damage in CRPC cells. These effects sensitize tumors to PARP inhibition, producing synergistic growth suppression with olaparib in vitro and significantly delayed tumor progression in vivo. Pyruvate rescue confirms ROS‐dependent activity.

Bottom Dissipation in Finite-Depth Water Waves

Coastal Engineering 1978, 1978
The dissipation of wave energy by various bottom mechanisms plays an important role in the spectral transformation of waves as they propagate from deep to shallow water. Three bottom dissipation mechanisms are discussed. The bottom friction mechanism is investigated in detail and a method for calculating the friction coefficient is proposed. The method

Recurrent cancer‐associated ERBB4 mutations are transforming and confer resistance to targeted therapies

Molecular Oncology, EarlyView.
We show that the majority of the 18 analyzed recurrent cancer‐associated ERBB4 mutations are transforming. The most potent mutations are activating, co‐operate with other ERBB receptors, and are sensitive to pan‐ERBB inhibitors. Activating ERBB4 mutations also promote therapy resistance in EGFR‐mutant lung cancer.
