Epidemic modelling of bovine tuberculosis in cattle herds and badgers in Ireland [PDF]
arXiv, 2020 Bovine tuberculosis, a disease that affects cattle and badgers in Ireland, was studied via stochastic epidemic modeling using incidence data from the Four Area Project (Griffin et al., 2005). The Four Area Project was a large scale field trial conducted in four diverse farming regions of Ireland over a five-year period (1997-2002) to evaluate the ...

The Effects of Land-use Change on Brucellosis Transmission in the Greater Yellowstone Ecosystem: A Three Species Mathematical-Epidemiological Model [PDF]
arXiv, 2022 This paper models brucellosis transmission between elk, cattle, and bison, of high conservation value, in the Greater Yellowstone Ecosystem (GYE). It aims to show how landscape changes in the GYE concomitantly impact brucellosis prevalence in the three species.

Advanced Energy Materials, EarlyView.The double perovskite BaSrNiWO6 is developed as an oxygen evolution reaction catalyst. B‐site W6+ dissolution drives in situ reconstruction of the surface to a disordered, NiO‐like layer. Consequently, local oxygen species are activated for a surface lattice oxygen evolution mechanism (sLOEM).

Cattle Detection Occlusion Problem [PDF]
arXiv, 2022 The management of cattle over a huge area is still a challenging problem in the farming sector. With evolution in technology, Unmanned aerial vehicles (UAVs) with consumer level digital cameras are becoming a popular alternative to manual animal censuses for livestock estimation since they are less risky and expensive.This paper evaluated and compared ...

Global economic effects of war‐induced agricultural export declines from Ukraine
Applied Economic Perspectives and Policy, EarlyView.Abstract The war in Ukraine caused export disruptions that jeopardized the availability and affordability of agricultural and food products around the world. This research employs a computable general equilibrium modeling framework to understand the global economic effects of war‐induced agricultural export declines from Ukraine, given the inability to
