A SEIRUC mathematical model for transmission dynamics of COVID-19

The world is still fighting against COVID-19, which has been lasting for more than a year. Till date, it has been a greatest challenge to human beings in fighting against COVID-19 since, the pathogen SARS-COV-2 that causes COVID-19 has significant bi...

The (un)detectability of trajectories in pilot-wave theory

Pilot wave theory endows particles with definite positions at all times governed by deterministic dynamics. However, individual particle trajectories are generically undetectable by experiment. This idea might seem to be contested in light of two pro...

Following the spacial dynamics of COVID-19 in Mexico and some notes

Actually, after one year it is recognized that the evolution of COVID-19 is different in each country or region around the world. In this paper, we do a revision to the date about COVID-19 evolution in Mexico, we explain where the main epicenter and...

Mental States as Macrostates Emerging from EEG Dynamics

Correlations between psychological and physiological phenomena form the basis for different medical and scientific disciplines, but the nature of this relation has not yet been fully understood. One conceptual option is to understand the mental as...

I found the bunker of a prepper family who went missing three years ago

Dr Daniel Vance was a smart man. Too smart for his own good, maybe. Forty years old, a lecturer in fluid dynamics with a mind made of shapes and numbers. No one knows why but one day, on a whim, he cr...

Burton-Cabrera-Frank theory for surfaces with alternating step types

Burton-Cabrera-Frank (BCF) theory has proven to be a versatile framework to relate surface morphology and dynamics during crystal growth to the underlying mechanisms of adatom diffusion and attachment at steps. For an important class of crystal surfa...

Dynamics of Fecal Coliform Bacteria along Canada's Coast

The vast coastline provides Canada with a flourishing seafood industry including bivalve shellfish production. To sustain a healthy bivalve molluscan shellfish production, the Canadian Shellfish Sanitation Program was established to monitor the healt...

Soft Gravitons Screen Couplings in de Sitter Space

The scale invariance of the quantum fluctuations in de Sitter space leads to the appearance of de Sitter symmetry breaking infra-red logarithms in the graviton propagator. We investigate physical effects of soft gravitons on the local dynamics of mat...

The non-minimal coupling constant and the primordial de Sitter state

Dynamical systems methods are used to investigate dynamics of a flat Friedmann-Robertson-Walker cosmological model with the non-minimally coupled scalar field and a potential function. Performed analysis distinguishes the value of non-minimal couplin...

Vortex shedding - Wikipedia

In fluid dynamics, vortex shedding is an oscillating flow that takes place when a fluid such as air or water flows past a bluff (as opposed to streamlined)
