Advanced Engineering Materials, EarlyView.Temporal power modulation increases weld depth in high‐power laser beam welding of dissimilar round bars by nearly 20% compared to same average continuously welded welding power. The mechanism of action also applies to sheet welding and depends on the inertia of keyhole depth for the modulated laser beam power.

Dynamically self-regular quantum harmonic black holes
Physics Letters B, 2015 The recently proposed UV self-complete quantum gravity program is a new and very interesting way to envision Planckian/trans-Planckian physics. In this new framework, high energy scattering is dominated by the creation of micro black holes, and it is ...

Near-extremal Kerr-like ECO in the Kerr/CFT correspondence in higher spin perturbations
European Physical Journal C: Particles and FieldsThe Kerr/CFT correspondence has been established to explore the quantum theory of gravity in the near-horizon geometry of an extreme Kerr black holes. The quantum gravitational corrections on the near-horizon region may manifest in form of a partially ...

Advanced Engineering Materials, EarlyView.In this study, how friction‐welding parameters (rotational speed, etc.) affect the morphology, distribution, and local thickness of the intermetallic compound layer (IMC‐layer) in friction‐welded steel‐aluminum hybrid components is investigated. In the results, it is shown that lower speeds (700 rpm) lead to a more uniform, thinner IMC‐layer (<0.5 μm),

Early scrambling and capped BTZ geometries
Journal of High Energy Physics, 2019 Geodesic probes in certain horizonless microstate geometries experience extreme tidal forces long before reaching the region where these geometries differ significantl from the extremal BTZ black hole.

Current Trends and Future Perspective for Cold Spray Metal‐Ceramic Composites
Advanced Engineering Materials, EarlyView.The use of cold spray (CS) technology for creating cermet deposits, combining ceramic and metallic components, is advancing rapidly. Cermets offer excellent temperature handling and erosion resistance for diverse applications. This review outlines the current state of the art, focusing on the deposition dynamics and strategies to optimize the ...

Certain Extremal Problems on a Classical Family of Univalent Functions
MathematicsConsider the collection A of analytic functions f defined within the open unit disk D, subject to the conditions f(0)=0 and f′(0)=1. For the parameter λ∈[0,1), define the subclass R(λ) as follows:R(λ):=f∈A:Ref′(z)>λ,z∈D.

On the ACC for lengths of extremal rays [PDF]
arXiv, 2011 We discuss the ascending chain condition for lengths of extremal rays. We prove that the lengths of extremal rays of $n$-dimensional $\mathbb Q$-factorial toric Fano varieties with Picard number one satisfy the ascending chain condition.

Impact of Surface Roughness on the Yield Drop of Hot‐Rolled AZX311 Mg Alloy
Advanced Engineering Materials, EarlyView.Rough‐surfaced AZX311 Mg alloy samples have significantly lower yield strength than polished ones due to stress concentrators forming at V‐notch irregularities. Surface profilometry confirms higher Ra values for rough samples. Highest hardness values were observed near scratched surfaces, indicating strain localization effects near the rough surface ...

A meet-in-the-middle algorithm for finding extremal restricted additive 2-bases [PDF]
Journal of Integer Sequences, Vol. 17 (2014), Article 14.6.8, 2014 An additive 2-basis with range n is restricted if its largest element is n/2. Among the restricted 2-bases of given length k, the ones that have the greatest range are extremal restricted. We describe an algorithm that finds the extremal restricted 2-bases of a given length, and we list them for lengths up to k = 41.
