Gaussian Process Approach for Model-independent Reconstruction of f(Q) Gravity with Direct Hubble Measurements

The Astrophysical Journal
The increase of discrepancy in the standard procedure to choose the arbitrary functional form of the Lagrangian f ( Q ) motivates us to solve this issue in modified theories of gravity. In this regard, we investigate the Gaussian process, which allows us

Time‐Dependent Oxidation and Scale Evolution of a Wrought Co/Ni‐Based Superalloy

Advanced Engineering Materials, EarlyView.
This study shows how a new wrought Co/Ni‐based superalloy resists oxidation at 800 ∘$^\circ$C. The oxide scale changes from rough, fast‐growing spinel to a dense, protective chromia–alumina layer. Atom probe analysis reveals tiny refractory‐rich bubbles at the interface that mark the transition to long‐term, diffusion‐controlled protection ...

Impact of Teleparallelism on Addressing Current Tensions and Exploring the GW Cosmology

The Astrophysical Journal
The H _0 and S _8 tensions highlight critical discrepancies in modern cosmology, challenging the standard Lambda cold dark matter model. The H _0 tension arises from conflicting measurements between local probes and early-Universe predictions. Similarly,

Understanding the Stochastic Nature of Process Parameter Development of Blown Powder Laser Beam Directed Energy Deposition Additive Manufacturing of Pure Molybdenum

Advanced Engineering Materials, EarlyView.
Identified through the use of statistical design of experiments and metallographic investigation, this study exposes the stochastic origins of intergranular cracks in blown powder laser beam directed energy deposition additive manufacturing of pure molybdenum. It further demonstrates a successful crack mitigation approach with direct correlation to the
