Synthetic characterization and Structural Properties of Nanocellulose from Moringa oleifera seeds

open access: yesJournal of Nigerian Society of Physical Sciences, 2021
In this research, nanocellulose is isolated from Moringa oleifera seed using acid hydrolysis and the structural properties were determined. X-ray diffraction (XRD) and Fourier transform infrared (FTIR) spectroscopy were used for the characterization of ...

Group chasing tactics: how to catch a faster prey

open access: yesNew Journal of Physics, 2017
We propose a bio-inspired, agent-based approach to describe the natural phenomenon of group chasing in both two and three dimensions. Using a set of local interaction rules we created a continuous-space and discrete-time model with time delay, external ...

Enhanced tensor non-Gaussianities in presence of a source

open access: yesEuropean Physical Journal C: Particles and Fields, 2020
We address the possibility of having an enhanced signal for tensor non-Gaussianities in presence of a source, as a signature of Primordial Gravitational Waves.

THERMODYNAMIC LIMIT IN STATISTICAL PHYSICS [PDF]

open access: yesInternational Journal of Modern Physics B, 2014
The thermodynamic limit in statistical thermodynamics of many-particle systems is an important but often overlooked issue in the various applied studies of condensed matter physics. To settle this issue, we review tersely the past and present disposition of thermodynamic limiting procedure in the structure of the contemporary statistical mechanics and ...

Inflation, (p)reheating and neutrino anomalies: production of sterile neutrinos with secret interactions

open access: yesEuropean Physical Journal C: Particles and Fields, 2019
A number of experimental anomalies involving neutrinos hint towards the existence of at least an extra (a very light) sterile neutrino. However, such a species, appreciably mixing with the active neutrinos, is disfavored by different cosmological ...

Hospitalization Through Families’ Eyes: Comparing Inpatient Care Quality for Children With Sickle Cell Disease and Cystic Fibrosis in Canada

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Sickle cell disease (SCD) is a chronic, inherited hemoglobinopathy that requires frequent hospitalization for disease‐related complications. Canadian data on inpatient care is limited. This study compared caregiver‐reported hospital experiences of children with SCD to those with cystic fibrosis (CF), a chronic, autosomal recessive ...

The Role of Hematopoietic Cell Transplantation in Ataxia‐Telangiectasia

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Ataxia‐telangiectasia (A‐T) is a DNA repair disorder characterized by neurodegeneration, immunodeficiency, and cancer predisposition. Hematopoietic cell transplantation (HCT) is an established therapy in related disorders such as Fanconi anemia (FA) and Nijmegen breakage syndrome (NBS), but its role in A‐T is unclear.

Probability in physics: stochastic, statistical, quantum [PDF]

open access: yes, 2013
I review the role of probability in contemporary physics and the origin of probabilistic time asymmetry, beginning with the pre-quantum case (both stochastic mechanics and classical statistical mechanics) but concentrating on quantum theory. I argue that

Enhancing Statistical Physics Learning: Rhetoric and Emotion in Moodle for Physics Education

open access: yesJurnal Pendidikan Fisika Indonesia, 2023
The Learning Management System in science education has become crucial in modern educational settings. However, there is a lack of comprehensive resources to guide the implementation of hedonic and pragmatic qualities in UX.

Statistical physics of self-replication [PDF]

open access: yesThe Journal of Chemical Physics, 2013
Self-replication is a capacity common to every species of living thing, and simple physical intuition dictates that such a process must invariably be fueled by the production of entropy. Here, we undertake to make this intuition rigorous and quantitative by deriving a lower bound for the amount of heat that is produced during a process of self ...
