Quaternion Spin

open access: yesMathematics
We present an analysis of the Dirac equation when the spin symmetry is changed from SU(2) to the quaternion group, Q8, achieved by multiplying one of the gamma matrices by the imaginary number, i. The reason for doing this is to introduce a bivector into

Spin Helicity and the Disproof of Bell’s Theorem

open access: yesQuantum Reports
Under the quaternion group, Q8, spin helicity emerges as a crucial element of the reality of spin and is complementary to its polarization. We show that the correlation in EPR coincidence experiments is conserved upon separation from a singlet state and ...

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.

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 ...

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

Exploring an Alternative to mRNA Vaccine Cold Chain Storage: MRNA‐Lipid Nanoparticle Stability When Dried in a Polymer Matrix

open access: yesAdvanced Functional Materials, EarlyView.
The nanostructure, size, and function of mRNA‐loaded lipid nanoparticles are evaluated before drying, within polymer microneedles, and after rehydration. The results reveal the polymer and LNP loadings required to recover nanostructure and preserve the delivery performance in dry‐state formulations.

The Double-Slit Experiment in the Bivector Standard Model

open access: yesAxioms
The double-slit experiment is commonly interpreted as evidence that a single electron must be described by a spatially extended wavefunction whose path amplitudes interfere.

Building Agricultural Knowledge of Soil-biodegradable Plastic Mulch

open access: yesHortTechnology, 2023
The use of polyethylene (PE) mulch causes environmental pollution where incomplete removal leaves fragments susceptible to escape to ecosystems, such as the ocean, where they can cause ecological harm.
