A Unifying Approach to Self‐Organizing Systems Interacting via Conservation Laws
Advanced Intelligent Discovery, EarlyView.The article develops a unified way to model and analyze self‐organizing systems whose interactions are constrained by conservation laws. It represents physical/biological/engineered networks as graphs and builds projection operators (from incidence/cycle structure) that enforce those constraints and decompose network variables into constrained versus ...

Real Wage Convergence in Romania: Empirical Evidence Based on Club Converging
Studia Universitatis Vasile Goldis Arad, Seria Stiinte Economice, 2020 The study aims to explore the real wage convergence across the 42 Romanian counties from 1991 to 2016 by using the convergence algorithm developed by Phillips and Sul (2007). The process of divergence is identified in the period of 1991-2016 as well as a

Unfused transverse foramen of the atlas vertebra in the Neandertal lineage fossils
The Anatomical Record, EarlyView.Abstract In anatomically modern humans, the atlas can display an unfused transverse foramen (UTF) but currently the presence of UTF in the Neandertal lineage is uncertain due to a scarcity of prevalence studies and no exhaustive record of its presence throughout the entire hominin fossil record.

The Anatomical Record, EarlyView.Abstract The preauricular sulcus has long been debated as a pelvic feature variably attributed to obstetric stress, ligamentous traction, and broader biomechanical processes. To clarify its determinants, we analyzed 409 adult individuals from three archeological and one early modern skeletal collection from the Iberian Peninsula, integrating graded ...

A Seismic Inversion Problem for an Anisotropic, Inhomogeneous Medium [PDF]
, 2002 In this report, we consider the propagation of seismic waves through a medium that can be subdivided into of two distinct parts. The upper part is assumed to be azimuthally symmetric, linearly nonuniform with increasing depth, and the velocity dependence
