On nonhomogeneous Choquard equation with Hardy–Littlewood–Sobolev critical nonlinearity

Boundary Value Problems
In this paper, we investigate the existence of nontrivial solutions to the following critical nonhomogeneous Choquard equation: { − Δ u = λ u + ∫ Ω ( | u ( y ) | 2 α ∗ | x − y | α d y ) | u | 2 α ∗ − 2 u + f ( x ) i n Ω , u ∈ H 0 1 ( Ω ) , $$ \left ...

Degenerations of cubic fourfolds and holomorphic symplectic geometry [PDF]

, 2012
In this thesis we study deformations of varieties of lines on smooth cubic hypersurfaces of the 5-dimensional complex projective space. These cubic hypersurfaces are also called cubic fourfolds.

On linear codes with random multiplier vectors and the maximum trace dimension property

Journal of Mathematical Cryptology
Let CC be a linear code of length nn and dimension kk over the finite field Fqm{{\mathbb{F}}}_{{q}^{m}}. The trace code Tr(C){\rm{Tr}}\left(C) is a linear code of the same length nn over the subfield Fq{{\mathbb{F}}}_{q}.

Microstructure Reconstruction in Battery Electrodes Using Machine Learning Based on Low‐Voltage Focused Ion Beam–Scanning Electron Microscopy Tomography Images

Advanced Engineering Materials, EarlyView.
Low‐voltage FIB‐SEM tomography combined with a image preprocessing pipeline improves phase contrast and enables reliable machine‐learning segmentation of conductive networks in lithium‐ion battery electrodes. Structural descriptors are extracted from segmented images, done semimanually and automated, and compared.

Inverse Identification of Energy‐Dependent Laser Absorptivity in NiTi Laser Powder‐Bed Fusion via Calibrated Melt Pool Simulation

Advanced Engineering Materials, EarlyView.
A combined experimental–computational framework identifies energy‐dependent laser absorptivity for NiTi in laser powder‐bed fusion, applicable to conduction and transition modes. Single‐track experiments and thermofluid smoothed particle hydrodynamics simulations are coupled through inverse analysis of melt pool geometry.
