DISTORTIONS IN THE EMPIRICAL INVESTIGATION OF ECONOMIC PHENOMENA [PDF]

Revista Română de Statistică, 2011
Study of the economic phenomena is a common practice, resulting in the need for understanding the complexity of the economic realities that are in a continuous process of expansion.

Rolling balls or trapping ions? How students relate models to real‐world phenomena in the physics laboratory

Science Education, 2023
AbstractThe creation and use of models in science is of great importance for knowledge production and communication. For example, toy models are often used as idealized explanatory models in physics education. Models can be a powerful tool for exploring phenomena in ways that facilitate learning.

An Open-Source Library for the Numerical Modeling of Mass-Transfer in Solid-Oxide Fuel Cells [PDF]

, 2012
The generation of direct current electricity using Solid Oxidize Fuel Cells (SOFCs) involves several interplaying transport phenomena. Their simulation is crucial for the design and optimization of reliable and competitive equipment, and for the eventual

MODELING THE TRANSMISSION PHENOMENA OF COVID-19 INFECTION WITH THE EFFECT OF VACCINATION VIA NONINTEGER DERIVATIVE UNDER REAL STATISTIC

Fractals, 2022
The infection of coronavirus (COVID-19) is a dangerous and life-threatening disease which spread to almost all parts of the globe. We present a mathematical model for the transmission of COVID-19 with vaccination effects. The basic properties of fractional calculus are presented for the inspection of the model. We calculate the equilibria of the model

By dawn or dusk—how circadian timing rewrites bacterial infection outcomes

FEBS Letters, EarlyView.
The circadian clock shapes immune function, yet its influence on infection outcomes is only beginning to be understood. This review highlights how circadian timing alters host responses to the bacterial pathogens Salmonella enterica, Listeria monocytogenes, and Streptococcus pneumoniae revealing that the effectiveness of immune defense depends not only

A robust study on the listeriosis disease by adopting fractal-fractional operators

Alexandria Engineering Journal, 2022
Listeriosis is one of the zoonotic diseases affecting most parts of the Sub-Saharan countries. The infection is often transmitted by eating and it can also pass by respiratory and direct contact.

BRANCHING PROCESS MODELLING: A TOOL FOR DECIPHERING COMPLEX REAL-WORLD PHENOMENA USING R PROGRAMMING

FUDMA JOURNAL OF SCIENCES, 2023
The reproduction of organisms such as human beings, cells or neutrons can be modeled via branching processes.The theory of branching processes offers suitable mathematical models to depict the chance-based progression of systems, where elements like cells, particles, or general individuals replicate and perish over a certain lifespan.

Relevance of SIR Model for Real-world Spreading Phenomena: Experiments on a Large-scale P2P System [PDF]

2012 IEEE/ACM International Conference on Advances in Social Networks Analysis and Mining, 2012
Understanding the spread of information on complex networks is a key issue from a theoretical and applied perspective. Despite the effort in developing theoretical models for this phenomenon, gauging them with large-scale real-world data remains an important challenge due to the scarcity of open, extensive and detailed data.

The role and implications of mammalian cellular circadian entrainment

FEBS Letters, EarlyView.
At their most fundamental level, mammalian circadian rhythms occur inside every individual cell. To tell the correct time, cells must align (or ‘entrain’) their circadian rhythm to the external environment. In this review, we highlight how cells entrain to the major circadian cues of light, feeding and temperature, and the implications this has for our
