A Unifying Approach to Self‐Organizing Systems Interacting via Conservation Laws

open access: yesAdvanced 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 ...

Physical Properties of Transition Metal Hydride Superconductors Mg2TmH6 (Tm = Rh, Pd, Ir, Pt) by First‐Principles Calculations

open access: yesAdvanced Physics Research, EarlyView.
The electronic band structure determines all the charge transport properties of crystalline solids. It also controls the optical response of the material. Bonding characters are strongly influenced by the band structure. The band structures of Mg2TmH6 (Tm = Rh, Pd, Ir, Pt) compounds shown above confirm their metallic nature.

Real Wage Convergence in Romania: Empirical Evidence Based on Club Converging

open access: yesStudia 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

Pelvic morphology and body size in relation to the preauricular sulcus: Evidence from medieval to modern Iberia

open access: yesThe 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 ...

Comparison of Healthcare Utilization Before Diagnosis Between Non‐Advanced and Advanced Lung Cancer Patients: A Study Among 72,851 Cases in Germany

open access: yesInternational Journal of Cancer, EarlyView.
ABSTRACT There is no study from Germany on the association between stage of lung cancer (LC) and patient characteristics. We aimed to compare advanced versus non‐advanced LC cases regarding indicators of healthcare utilization. Using claims data covering 20% of the German population, we included LC patients diagnosed between 2013 and 2019.
