Charting cellular differentiation trajectories with Ricci flow

Nature Communications
Complex biological processes, such as cellular differentiation, require intricate rewiring of intra-cellular signalling networks. Previous characterisations revealed a raised network entropy underlies less differentiated and malignant cell states.

Structural properties of the sets of positively curved Riemannian metrics on generalized Wallach spaces

Қарағанды университетінің хабаршысы. Математика сериясы
In the present paper sets related to invariant Riemannian metrics of positive sectional and (or) Ricci curvature on generalized Wallach spaces are considered.

Direct Photopatterning of Green Solvent‐Processed 2D Nanomaterials for Wafer‐Scale Electronics

Advanced Materials, Volume 37, Issue 40, October 9, 2025.
A photocross‐linking strategy is proposed for the patterning and integration of scalable vertical van der Waals heterostructures such as field‐effect transistors, logic gates, and memory devices composed of 2D nanomaterials by UV light‐sensitive cross‐linker in isopropyl alcohol.

The Hall Effects of Vortex Light in Optical Materials

Advanced Photonics Research, Volume 6, Issue 10, October 2025.
This article models optical materials as curved spacetime to investigate light propagation, finding that the deflection angle for light with spin σ and intrinsic orbital angular momentum ℓ follows ϑ ∝ 2σ + ℓ$\vartheta \propto 2 \text{&sgr; } + ℓ$.

η-Ricci Solitons on Sasakian 3-Manifolds

Annals of the West University of Timisoara: Mathematics and Computer Science, 2017
In this paper we study η-Ricci solitons on Sasakian 3-manifolds. Among others we prove that an η-Ricci soliton on a Sasakian 3-manifold is an η-Einstien manifold.

On discrete subgroups of the complex unit ball

Mathematische Nachrichten, Volume 298, Issue 10, Page 3272-3286, October 2025.
Abstract In this paper, we study conditions for a discrete subgroup of the automorphism group of the n$n$‐dimensional complex unit ball to be of convergence type or second kind, connecting these classifications to the existence of Green's functions and subharmonic or harmonic functions on its quotient space.
