visual spatial attention and spatial working memory do not draw on Shared Capacity limited core processes
Quarterly Journal of Experimental Psychology, 2020Co-Authors: Christina J Howard, Rebekah Pole, Paulina Montgomery, Amanda Woodward, D Guest, Bradley Standen, Christopher Kent, Emily M CroweAbstract:The extent to which similar Capacity limits in visual attention and visual working memory indicate a common Shared underlying mechanism is currently still debated. In the spatial domain, the multip...

Foliar water uptake: a common water acquisition strategy for plants of the redwood forest
Oecologia, 2009Co-Authors: Emily B. Limm, Kevin A. Simonin, Aron G. Bothman, Todd E. DawsonAbstract:Evaluations of plant water use in ecosystems around the world reveal a Shared Capacity by many different species to absorb rain, dew, or fog water directly into their leaves or plant crowns. This mode of water uptake provides an important water subsidy that relieves foliar water stress. Our study provides the first comparative evaluation of foliar uptake Capacity among the dominant plant taxa from the coast redwood ecosystem of California where crown-wetting events by summertime fog frequently occur during an otherwise drought-prone season. Previous research demonstrated that the dominant overstory tree species, Sequoia sempervirens , takes up fog water by both its roots (via drip from the crown to the soil) and directly through its leaf surfaces. The present study adds to these early findings and shows that 80% of the dominant species from the redwood forest exhibit this foliar uptake water acquisition strategy. The plants studied include canopy trees, understory ferns, and shrubs. Our results also show that foliar uptake provides direct hydration to leaves, increasing leaf water content by 2–11%. In addition, 60% of redwood forest species investigated demonstrate nocturnal stomatal conductance to water vapor. Such findings indicate that even species unable to absorb water directly into their foliage may still receive indirect benefits from nocturnal leaf wetting through suppressed transpiration. For these species, leaf-wetting events enhance the efficacy of nighttime re-equilibration with available soil water and therefore also increase pre-dawn leaf water potentials.

impact of power sharing method on battery life extension in hess for grid ancillary services
IEEE Transactions on Energy Conversion, 2019Co-Authors: Mohamed Bahloul, Shafiuzzaman K KhademAbstract:Hybrid energy storage system (HESS) based on Li-ion and supercapacitor (SC) can play a potential role to stabilize the grid by providing the fast frequency ancillary services. The SC helps to reduce the battery charge/discharge stress and, hence, assists to extend the battery lifespan. The power sharing method (PSM) is the heart in control part to improve the HESS performance and reduce the battery stress. This paper proposes a hybrid PSM and investigates its impact on battery life extension along with its relation to the system design and regulation signal. The performance of hybrid PSM is compared with three other PSMs (low-pass filter, first and second rule based) in a 10 MW/10 MWh full-active parallel HESS for frequency regulation service in two networks: U.K. (national grid) and USA (PJM). Considering maximum possible battery lifetime upto 25 years, result shows that the hybrid PSM approach allows a degree of the better performance for both grid while the sharing of SC is kept maximum 2.0% and 2.5% (for U.S. and U.K. grid, respectively) of the HESS Capacity. This study also analyses the impact of PSM on Shared Capacity and design of HESS for different grid regulation signals.

PHYSIOLOGICAL ECOLOGY- ORIGINAL PAPER Foliar water uptake: a common water acquisition strategy for plants of the redwood forest
2016Co-Authors: Aron G. Bothman, Æ Todd, E.
