Because many different sensory modalities contribute to spatial learning in rodents, it has been difficult to determine whether spatial navigation can be guided solely by visual cues. Rodents moving within physical environments with visual cues engage a variety of nonvisual sensory systems that cannot be easily inhibited without lesioning brain areas. Virtual reality offers a unique approach to...

For a water-secure present and future, there is need for transition from water scarcity towards security. This necessitates look at the complex relationships, interdependencies, between other resources, institutions governing them. Nexus approach encompasses these interdependencies. paper focused on water–food nexus through lens of virtual (VW) flows concept with aim to explore role VW in secur...

With the rapid development of socio-economic system and close connection inter-regional trade, physical water consumption in production virtual flow associated with trade are both have a significant impact on local systems, especially megacities. Beijing is political, economic cultural center China, which megacity that has severe scarcity. To evaluate status-quo propose countermeasures, this st...

background: in-service education is one of the best and major methods to provide, train and improve the performance of the staffs. this study aims to determine the strengths and weaknesses of the virtual trainings from the staffs' perspective of mashhad university of medical sciences. methods: this is a cross-sectional study conducted among staffs from different parts of the therapy depart...

Introduction: Muscle strength has shown different responses to the cooling of neuromuscular tissue and its behavior is still unclear. Objective: To verify the behavior of maximum grip strength before and after forearm cooling. Methods: The cooling intervention consisted of immersing the forearm up to the elbow in water cooled to 10°C. Grip strength was assessed using a dynamometer prior to cool...

The ability to produce from low permeability, tight gas reservoirs is directly tied to the ability to repetitively perform successful hydraulic fracturing in a series of closely spaced wells. The key question is whether the induced fractures remain open and permeable, which is in part a function of the stress field and the emplacement of proppant. We study the ability to detect and characterize...

An agent-based modeling of virtual ecosystems is presented. A virtual ecosystem develops by plant competition according to biologically inspired rules and tends to reach stability. Virtual agents enter the ecosystem and perform actions that favor certain plant species and cause system instabilities. Agents liberate space for some plant species by eliminating the others, they take out old plants...

We present an optimization of the height-field water-column based approach for water simulation, providing three-dimensional animation of water flow on natural terrains. Our approach eliminates the storage and management of redundant virtual pipes between columns of water and also removes output dependency for parallel implementation, making it efficient for interactive computer graphics applic...
