Exact characterization of O(n) tricriticality in two dimensions

, 2005
We propose exact expressions for the conformal anomaly and for three critical exponents of the tricritical O(n) loop model as a function of n in the range $-2 \leq n \leq 3/2$. These findings are based on an analogy with known relations between Potts and

Localizing Efforts to Prevent Sexual Exploitation and Abuse in Humanitarian Aid: Evolving Experiences of Power and Agency in Lebanon

Public Administration and Development, EarlyView.
ABSTRACT Efforts to address gender‐based violence in humanitarian settings increasingly call for recognition of and funding to local women‐led organizations and women's rights organizations for long‐term response. The Empowered Aid initiative seeks to address sexual exploitation and abuse by working with local organizations as well as the refugee women

COMPUTER SIMULATION OF PHASE TRANSITIONS IN THE TWODIMENSIONAL STRUCTURES DESCRIBED THREE-VERTEX ANTIFERROMAGNETIC POTTS MODE ON A TRIANGULAR LATTICE

Вестник Дагестанского государственного технического университета: Технические науки, 2016
Using Monte-Carlo simulations, we investigated phase transitions and frustrations in the three-state Potts model on a triangular lattice with allowance for antiferromagnetic exchange interactions between nearest- neighbors J1 and next- nearest- neighbors

Overlap of two topological phases in the antiferromagnetic Potts model

, 2018
By controlling the vortex core energy, the three-state ferromagnetic Potts model can exhibit two types of topological paradigms, including the quasi-long-range ordered phase and the vortex lattice phase [PRL 116, 097206 (2016)].

The Super-Potts glass: a new disordered model for glass-forming liquids

, 2014
We introduce a new disordered system, the Super-Potts model, which is a more frustrated version of the Potts glass. Its elementary degrees of freedom are variables that can take M values and are coupled via pair-wise interactions. Its exact solution on a

From wild to tamed: Reimagining novel crops through omics and local plant diversity

PLANTS, PEOPLE, PLANET, EarlyView.
The global food system faces growing pressure from climate change, biodiversity loss, and rising nutritional demands. Agriculture has increased yields but reduced crop diversity, flavor, and nutritional quality, leaving societies vulnerable and dependent on a narrow set of staple species.

Ground‐based robotic remote sensing for standardized biodiversity monitoring in coastal habitats

Remote Sensing in Ecology and Conservation, EarlyView.
Illustrated workflow of the proposed citizen‐to‐robot monitoring pipeline: (i) expert‐validated citizen observations are translated into AI models, (ii) deployed on a ground‐based robotic platform for proximal sensing of coastal dune habitats, (iii) enabling standardized detection of ecological targets (e.g., Pancratium maritimum & Brithys crini), and (

Coupled Minimal Models with and without Disorder

, 1997
We analyse in this article the critical behavior of $M$ $q_1$-state Potts models coupled to $N$ $q_2$-state Potts models ($q_1,q_2\in [2..4]$) with and without disorder. The technics we use are based on perturbed conformal theories.

The Impact of Dust Particles on the Function of Screen‐Printed Triple‐Mesoscopic Perovskite Solar Cells

Small, EarlyView.
Screen‐printed mesoporous carbon perovskite solar cells offer an accessible route to scalable green energy. This study investigates the impact of dust particle contamination during the manufacture of this type of solar cell. Results suggest clean rooms may be unnecessary if strict cleanliness is maintained during storage and printing processes in ...

Apical constriction requires patterned apical surface remodeling to synchronize cellular deformation

eLife
Apical constriction is a basic mechanism for epithelial morphogenesis, making columnar cells into wedge shape and bending a flat cell sheet. It has long been thought that an apically localized myosin generates a contractile force and drives the cell ...
