Complex networks on hyperbolic surfaces [PDF]

open access: yesPhysica A: Statistical Mechanics and its Applications, 2005
We explore a novel method to generate and characterize complex networks by means of their embedding on hyperbolic surfaces. Evolution through local elementary moves allows the exploration of the ensemble of networks which share common embeddings and consequently share similar hierarchical properties.

Elucidation of the origin of chiral amplification in discrete molecular polyhedra

open access: yesNature Communications, 2018
The sergeants-and-soldiers effect, in which a few chiral units induce chirality in a large number of achiral molecules, is difficult to quantify at the molecular level.

Automation of Operations Design for Complex-Shaped Surfaces Processing [PDF]

open access: yesMATEC Web of Conferences, 2019
Research work is aimed at modeling the process of milling surfaces of complex shape in automated CAD/CAM systems. To reduce labour input of this process, an algorithm for designing milling operations is proposed.

Matlab Program for Determining the Inertia Characteristics of Flat Surfaces with Monte Carlo Algorithms

open access: yesThe Annals of “Dunarea de Jos” University of Galati. Fascicle IX, Metallurgy and Materials Science, 2022
This paper presents a Matlab program for calculating the inertia tensor for complex plane surfaces. The calculation of the moments of inertia for plane surfaces with classical methods involves decomposing the surfaces into primitive surfaces and applying

Social interactions in the Burkholderia cepacia complex : biofilms and quorum sensing [PDF]

open access: yes, 2010
Burkholderia cepacia complex bacteria are opportunistic pathogens that cause respiratory tract infections in susceptible patients, mainly people with cystic fibrosis. There is convincing evidence that B.

Migration of T cells on surfaces containing complex nanotopography. [PDF]

open access: yesPLoS ONE, 2013
T cells navigate complex microenvironments to initiate and modulate antigen-specific immune responses. While recent intravital microscopy study revealed that migration of T cells were guided by various tissue microstructures containing unique nanoscale ...

Differential geometric global smoothings of simple normal crossing complex surfaces with trivial canonical bundle

open access: yesComplex Manifolds, 2023
Let XX be a simple normal crossing (SNC) compact complex surface with trivial canonical bundle which includes triple intersections. We prove that if XX is dd-semistable, then there exists a family of smoothings in a differential geometric sense. This can
