First photographic evidence of the Asiatic Golden Cat Catopuma temminckii Vigors & Horsfield, 1827 (Mammalia: Carnivora: Felidae) in Sakteng Wildlife Sanctuary, Bhutan

open access: yesJournal of Threatened Taxa, 2020
The Asiatic Golden Cat Catopuma temminckii is among Asia’s least studied wild felids.  We report the first photographic evidence of its presence in Sakteng Wildlife Sanctuary, eastern Bhutan, where it was recorded above 3,000m.

The Classical Origin of Spin: Vectors Versus Bivectors

open access: yesAxioms
There are two ways of linearizing the Klein–Gordon equation: Dirac’s choice, which introduces a matter–antimatter pair, and a second approach using a bivector, which Dirac did not consider.

The Fine-Structure Constant in the Bivector Standard Model

open access: yesAxioms
The geometrical view of the electron as a spinning bivector leads to the partitioning of the electron’s energy into internal and external. The reduced Compton wavelength, λ¯C, is taken as the radius of the inertial ring (a disc), while re characterizes ...

Seasonal micro-migration in a farm-island population of striated caracaras (Phalcoboenus australis) in the Falkland Islands

open access: yesMovement Ecology, 2018
Background The extent to which seasonal changes in food availability affect small-scale movements in free-ranging populations of birds of prey is relatively little studied.

EPR Correlations Using Quaternion Spin

open access: yesQuantum Reports
We present a statistical simulation replicating the correlation observed in EPR coincidence experiments without needing non-local connectivity. We define spin coherence as a spin attribute that complements polarization by being anti-symmetric and ...

The Zitterbewegung in the Bivector Standard Model

open access: yesAxioms
We show that the Zitterbewegung of the electron arises as a real internal motion when spin is treated as a classical bivector rather than as a point fermion of the Dirac equation.

Necropsy survey of gastric ulcers in a population of aged donkeys: prevalence, lesion description and risk factors

open access: yesAnimal, 2009
There is no information about the prevalence of gastric ulceration in donkeys or potential risk factors for its presence in donkeys. The donkey is a stoic, hardy animal that has not previously been thought to suffer from this disease.

An assessment of turtle communities in Bach Ma National Park, Vietnam

open access: yesNature Conservation Research: Заповедная наука, 2023
Most of the extraordinary biodiversity richness of South-East Asian countries is concentrated in the national parks and other Protected Areas, with species-rich turtle communities surviving mostly in these reserves where their natural habitats are better

Messaging inclusion with consequence: U.S. sanctuary cities and immigrant wellbeing

open access: yesJournal of Migration and Health, 2023
In the United States (U.S.), sanctuary cities have increasingly garnered public attention as places dedicated to increasing immigrant safety, inclusion, and health. These cities primarily rely on limiting local police cooperation with federal immigration
