Spatial expansions and travelling waves of rabies in vampire bats [PDF]

open access: yes, 2016
A major obstacle to anticipating the cross-species transmission of zoonotic diseases and developing novel strategies for their control is the scarcity of data informing how these pathogens circulate within natural reservoir populations.

Mixed‐Phase TiO2 Nanotubes Enhance Ru Nanoparticle Activity for Hydrogen Evolution in pH‐Neutral Electrolytes

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
Efficient water electrolysis in NaBr electrolyte is achieved using TiO2 nanotube supports decorated with Ru nanoparticles. A cooperative “job‐sharing” effect between the TiO2 proton‐storage support that provides protons to the Ru catalyst enhances hydrogen evolution, minimizes Ru demand and polarization losses, and delivers stable performance ...

Does the Visa-Free Policy Promote Inbound Tourism? Evidence From China

open access: yesSAGE Open
A visa-free policy is a tool for attracting foreign tourists, but existing studies evaluating its effects do not consider spatial spillover. This study, therefore, examined the effects of visa policies on urban inbound tourism with spatial spillover ...

Convergence, Spatial Interaction and Agglomeration Effects in the EU [PDF]

open access: yes, 2005
We investigate the convergence process among EU regions between 1980-2002 taking into account the effects of spatial heterogeneity and spatial spillover effects. The spatial regimes model allows for different steady-state growth paths.

Animal‐Based Brands Taking the Plant‐Based Opportunity: A Tasting Experiment Exploring Consumer Acceptance of Plant‐Based Brand Extensions

open access: yesAgribusiness, EarlyView.
ABSTRACT This study investigates how consumer taste and brand equity perceptions shape the acceptance of plant‐based milk products. Using a blind/informed tasting experiment, we evaluated consumers' willingness to buy (WTB) and taste perception of a plant‐based milk alternative produced by a traditional dairy brand, compared with competing plant‐based ...

Phase‐Change Alloys Enable Localized Reversible Stiffening and Actuation in Steerable Eversion Tip‐Growing Robots

open access: yesAdvanced Intelligent Systems, EarlyView.
This work presents a tip‐growing eversion robot that uses phase‐changing alloys for reversible stiffening and localized actuation, achieving 43× stiffness modulation, 15× force amplification, and segmental steering. The system enables precise navigation and force delivery in constrained, tortuous pathways.
