Mathematical Theory of Molecular Generation (MTMG): From Abstract Topology to Physical Chemical Structures

open access: yes
This paper introduces the Mathematical Theory of Molecular Generation (MTMG), a rigorous foundational framework that models molecular structures as a deterministic projection from abstract topological and algebraic spaces to physical molecular manifolds.

Streamline and Isotherm Visual Analysis of Darcy–Forchheimer von Karman Spinning Flow of Maxwell Fluid Over a Stretching Disk With Quadratic Temperature‐Dependent Heat Source

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT This research paper provides an extensive study of the effects of Darcy–Forchheimer von‐Karman spinning flow of Maxwell fluid across a stretching disk including the effect of heat generation based on a nonlinear function of temperature. The flow system is influenced by thermal radiations and Arrhenius activation energy.

PFUSRC-122: Ontological Triple Isomorphism of Mathematical Physics Ontological Issuance Package, Topological Valuation, Generalized Topological Uncertainty Principle and Their Full Correspondence with Classical Mathematical Theorems

open access: yes
Modern mathematics and physics suffer from a fundamental ontological schism: abstract mathematics, unconstrained by the 45° biconical cosmic topology, freely constructs logical structures of arbitrary dimensions and infinite degrees of freedom, while physical reality is rigidly confined by the Topological Self-Reduction of Dimensions (TSRD ...

Cooling Holes in Polymer Spur Gears: A Critical Analysis of Heat Dissipation Benefits and Mesh Stiffness Penalties

open access: yesJournal of Applied Polymer Science, EarlyView.
Cooling holes provide a simple passive cooling strategy for polymer spur gears, reducing maximum operating temperature by up to 9.39% while introducing a measurable gear mesh stiffness penalty. A validated response‐surface model reveals how hole size and location govern this thermal–mechanical trade‐off, enabling design optimization for thermally and ...

Born this way: Does variation in perinatal limb bone morphology predict adult locomotor repertoire in primates?

open access: yesThe Anatomical Record, EarlyView.
Abstract Primates show a high degree of locomotor diversity that engenders similar variance in limb bone cross‐sectional geometry and bending strength: leaping primates have stronger hindlimb bones whereas suspensory species have stronger forelimb bones.

Working with laws, regularities and singularities in biology: The evolution of mammalian red blood cell size as a case study

open access: yesThe Anatomical Record, EarlyView.
Abstract Phylogenetic comparative methods have been used in recent literature to work with laws and test for regularities (evolutionary associations of quantitative features) and evolutionary singularities (features that evolved in a single taxon). We analyzed these uses epistemologically, taking the evolution of red‐blood‐cell mean corpuscular volume (
