Topological Study of Zeolite Socony Mobil-5 via Degree-Based Topological Indices
Journal of Chemistry, 2021 Graph theory is a subdivision of discrete mathematics. In graph theory, a graph is made up of vertices connected through edges. Topological indices are numerical parameters or descriptors of graph.

Advanced Science, EarlyView.Donor‐derived tdTomato+ mature hepatocytes were FACS‐isolated and transplanted into Fah−/− host mice. During regeneration, these cells convert into proliferative, unipotent Afp+ rHeps. Their plasticity is governed by a PPARγ/AFP‐dependent metabolic switch, segregating into pro‐proliferative Afplow and pro‐survival Afphigh subpopulations.

Advanced Science, EarlyView.Triple‐negative breast cancer has a poor prognosis. Xanthatin directly targets and degrades CISD1, triggering ferroptosis through iron dysregulation. The concurrently activated mitophagy synergistically amplifies ferroptotic cell death. Xanthatin also demonstrates potent in vivo anti‐tumor efficacy with minimal toxicity, highlighting its therapeutic ...

Global Nitrogen Deposition Promotes Carbon Sink Formation in Terrestrial Ecosystems
Advanced Science, EarlyView.Nitrogen deposition alleviates ecosystem N limitation and enhances carbon sinks. Using 829 observations, we show 36% of deposited N is retained globally (39.15 Tg N yr−1), with distinct NHx and NOy contributions. This retention drives a terrestrial C sink of 0.88 Pg C yr−1 (25.48%), highlighting the importance of pool‐specific C:N stoichiometry ...

Rapid Assignment of Chemical Shifts From Crystal Structures in Solid‐State NMR
Angewandte Chemie, EarlyView.Chemical shift assignment in solids is a long and tedious process that relies on complex 1D and 2D NMR experiments. With prior knowledge of the 3D structure, this process can be significantly sped up by a Bayesian probabilistic assignment approach based on predicted chemical shifts.

Triangular Mesh Surface Subdivision Based on Graph Neural Network
Applied SciencesMesh subdivision is a common mesh-processing algorithm used to improve model accuracy and surface smoothness. Its classical scheme adopts a fixed linear vertex update strategy and is implemented iteratively, which often results in excessive mesh ...

A Study on C-Exponential Mean Labeling of Graphs
Journal of Mathematics, 2022 A function h is mentioned as a C-exponential mean labeling of a graph GV,E that has s vertices and r edges if h:VG⟶1,2,3,⋯,r+1 is injective and the generated function h∗:EG⟶2,3,4,⋯,r+1 defined by h∗ab=1/ehbhb/haha1/hb−ha, for all ab∈EG, is bijective.

Advanced Science, EarlyView.UHSR translates complex chemical behavior into clear and explainable equations. Applied to thin‐layer chromatography, it automatically uncovers the mathematical rules linking a molecule's structure to its polarity. This approach matches the accuracy of advanced AI while providing interpretable results, earning greater trust from chemists. The method is

Recursively-regular subdivisions and applications
Journal of Computational Geometry, 2016 We generalize regular subdivisions (polyhedral complexes resulting from the projection of the lower faces of a polyhedron) introducing the class of recursively-regular subdivisions.

Spanning subdivisions in Dirac graphs
Combinatorics, Probability and Computing, 2023 AbstractWe show that for every $n\in \mathbb N$ and $\log n\le d\lt n$ , if a graph $G$ has $N=\Theta (dn)$ vertices and minimum degree $(1+o(1))\frac{N}{2}$ , then it contains a spanning subdivision of every $n$ -vertex $d$ -regular graph.
