Is Einsteinian no-signalling violated in Bell tests?

open access: yesOpen Physics, 2017
Relativistic invariance is a physical law verified in several domains of physics. The impossibility of faster than light influences is not questioned by quantum theory.

Rethinking informal circularity through metanarratives: Tensions, insights and directions for management research

open access: yesInternational Journal of Management Reviews, EarlyView.
Abstract This study explores the intersection of the informal and circular economies and its implications for business, management and organization (BMO) scholarship and practice. Informal circularity, practices of collecting, reusing, repairing, recycling and repurposing materials outside formal economic, legal and regulatory arrangements, constitutes

Avian Eggshell Evolutionary Adaptations Inform Biomimetic Strategies for Next‑Generation Precision Cancer Theranostics

open access: yesAdvanced Oncology, Volume 1, Issue 1, December 2026.
ABSTRACT The avian eggshell is a sophisticated, multi‐functional biocomposite and, more importantly, an autonomous life‐support system evolved to safeguard embryonic development across dynamic and hostile environments. Discussing eggshell‐inspired biomaterials beyond simple structural imitation, this review translates these evolutionary survival ...

On the Smarandache Paradox [PDF]

open access: yes, 2003
The Smarandache Paradox is a very interesting paradox of logic because it has a background common sense. However, at the same time, it gets in a contradiction with itself. Although it may appear well cohesive, a careful look on the science definition and

From Tetracycline to Sulfamethoxazole: Photocatalytic Degradation and Mechanistic Insights in Aquatic Environments

open access: yesRare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT The pollution caused by antibiotics to aquatic ecosystems is becoming increasingly serious, thus more effective treatment methods are urgently required. Although the photocatalytic degradation behavior of tetracycline (TC) is relatively well understood, sulfamethoxazole (SMZ), an emerging pollutant originating from large‐scale livestock ...

The Computational Universe: Quantum Quirks and Everyday Reality, Actual Time, Free Will, the Classical Limit Problem in Quantum Loop Gravity and Causal Dynamical Triangulation

open access: yesQuantum Reports
The simulation analogy presented in this work enhances the accessibility of abstract quantum theories, specifically the stochastic hydrodynamic model (SQHM), by relating them to our daily experiences.

EPR Paradox

open access: yes
We present an exhaustive, first-principles mathematical proof that quantum non-locality (the EPR paradox) is an artifact of the continuous manifold assumption (R^3). By defining the physical vacuum strictly as the Gamma_120 quasicrystalline projection of the 8-dimensional E8 root lattice, we derive the exact invariant metric tensor for entangled states.

Carboxylate‐Driven Metal Pre‑Fixation COF@MOF Synthesis: Enabling Tailored Structural, Dimensional, and Defect Engineering

open access: yesAdvanced Science, Volume 13, Issue 51, 14 September 2026.
A universal metal pre‐fixation (MPF) strategy directs the precise crystallization of diverse metal‐organic frameworks (Co‐MOF, ZIF‐8, Fe‐MOF, UIO‐66) on covalent organic framework (PY‐COF) scaffolds. The resulting hierarchical hybrids exhibit tunable porosity, structural defective and dimensional, as well as enhanced performance in CH4/C2H6/C3H8 ...
