Neural-prior stochastic block model

Machine 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.

Statistical mechanics of biomolecular condensates via cavity methods

iScience, 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 ...

Inverse statistical physics of protein sequences: a key issues review [PDF]

Reports on progress in physics. Physical Society, 2017
In the course of evolution, proteins undergo important changes in their amino acid sequences, while their three-dimensional folded structure and their biological function remain remarkably conserved.

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

Heliyon, 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 of Cellulose from Moringa oleifera seeds and Potential Application in Water Purification

Journal 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.

Synthetic characterization and Structural Properties of Nanocellulose from Moringa oleifera seeds

Journal 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

New 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 ...

A reformulation of mechanics and electrodynamics

Heliyon, 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 ...

Enhanced tensor non-Gaussianities in presence of a source

European 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.

Statistical Physics of Structural Glasses

, 2000
This paper gives an introduction and brief overview of some of our recent work on the equilibrium thermodynamics of glasses. We have focused onto first principle computations in simple fragile glasses, starting from the two body interatomic potential.
