Social significance of community structure: Statistical view / Li, Hui-Jia ; Daniels, J J
Community structure analysis is a powerful tool for social networks, which can simplify their topological and functional analysis considerably. However, since community detection methods have random factors and real social networks obtained from complex systems always contain error edges, evaluating the significance of community structure partitioned is an urgent and important question. [...]

Potts model based on a Markov process computation solves the community structure problem effectively / Li, Hui-Jia ; Wang, Yong ; Wu, Ling-Yun ; Zhang, Junhua ; Zhang, Xiang-Sun
Potts model is a powerful tool to uncover community structure in complex networks. Here, we propose a new framework to reveal the optimal number of communities and stability of network structure by quantitatively analyzing the dynamics of Potts model. [...]

Identifying overlapping communities in social networks using multi-scale local information expansion / Li, Hui-Jia ; Zhang, Junhua ; Liu, Zhi-Ping ; Chen, Luonan ; Zhang, Xiang-Sun
Most existing approaches for community detection require complete information of the graph in a specific scale, which is impractical for many social networks. We propose a novel algorithm that does not embrace the universal approach but instead of trying to focus on local social ties and modeling multi-scales of social interactions occurring in those networks. [...]

Analysis of stability of community structure across multiple hierarchical levels / Li, Hui-Jia ; Zhang, Xiang-Sun
The analysis of stability of community structure is an important problem for scientists from many fields. Here, we propose a new framework to reveal hidden properties of community structure by quantitatively analyzing the dynamics of Potts model. [...]

Measuring robustness of community structure in complex networks / Li, Hui-Jia ; Wang, Hao ; Chen, Luonan
The theory of community structure is a powerful tool for real networks, which can simplify their topological and functional analysis considerably. However, since community detection methods have random factors and real social networks obtained from complex systems always contain error edges, evaluating the robustness of community structure is an urgent and important task.

Helical Disruptions in Small Loops of DNA / Zoli, Marco
The thermodynamical stability of DNA minicircles is investigated by means of path integral techniques. Hydrogen bonds between base pairs on complementary strands can be broken by thermal fluctuations and temporary fluctuational openings along the double helix are essential to biological functions such as transcription and replication of the genetic information. [...]

A mid-infrared Mueller ellipsometer with pseudo-achromatic optical elements / Garcia-Caurel, E (LPICM) ; Lizana, A (LPICM) ; Ndong, G (LPICM) ; Al-Bugami, B (LPICM) ; Bernon, C (LPICM) ; Al-Qahtani, E (LPICM) ; Rengnez, F (LPICM) ; De Martino, A (LPICM)
The purpose of this article is to present a new broadband Mueller ellipsometer designed to work in the mid-infrared range, from 3 to 14 microns. The Mueller ellipsometer, which can be mounted in reflection or in transmission configuration, consists of a polarization state generator (PSG), a sample holder, and a polarization state analyzer (PSA).

Trap-assisted decay spectroscopy with ISOLTRAP /IS473 collaboration
Penning traps are excellent high-precision mass spectrometers for radionuclides. The high-resolving power used for cleaning isobaric and even isomeric contaminants can be exploited to improve decay-spectroscopy studies by delivering purified samples. [...]
