Neural-prior stochastic block model

open access: yesMachine Learning: Science and Technology, 2023
The stochastic block model (SBM) is widely studied as a benchmark for graph clustering aka community detection. In practice, graph data often come with node attributes that bear additional information about the communities.

Scaling behavior of the Hirsch index for failure avalanches, percolation clusters, and paper citations

open access: yesFrontiers in Physics, 2022
A popular measure for citation inequalities of individual scientists has been the Hirsch index (h). If for any scientist the number nc of citations is plotted against the serial number np of the papers having those many citations (when the papers are ...

Statistical mechanics of biomolecular condensates via cavity methods

open access: yesiScience, 2023
Summary: Physical mechanisms of phase separation in living systems play key physiological roles and have recently been the focus of intensive studies. The strongly heterogeneous nature of such phenomena poses difficult modeling challenges that require ...

Synthetic Characterization of Cellulose from Moringa oleifera seeds and Potential Application in Water Purification

open access: yesJournal of Nigerian Society of Physical Sciences, 2021
The use of Moringa oleifera seeds for purifying water has been attempted locally in various forms without putting scientific potency of the material into consideration.

Critical temperature, surface tension and vapor density estimations of methanol using the scaled model

open access: yesHeliyon, 2019
In the present work, we applied scaled model to calculate surface tension, vapor densities and the critical temperatures of four different models of methanol: namely, H1, J1, J2 and L1 models.

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 ...

A reformulation of mechanics and electrodynamics

open access: yesHeliyon, 2017
Classical mechanics, as commonly taught in engineering and science, are confined to the conventional Newtonian theory. But classical mechanics has not really changed in substance since Newton formulation, describing simultaneous rotation and translation ...

Information in statistical physics

open access: yes, 2005
We review with a tutorial scope the information theory foundations of quantum statistical physics. Only a small proportion of the variables that characterize a system at the microscopic scale can be controlled, for both practical and theoretical reasons,

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 ...
