From Thin Films to Nanodots: Bottom-Up Integration of Fe<sub>3</sub>O<sub>4</sub> on Nb:STO for Functional Oxide Nanostructures. [PDF]
Adv MaterScalable bottom‐up fabrication of Fe3O4 nanodots on Nb:SrTiO3 using anodic alumina templates enables long‐range ordered arrays with diameters down to 30 nm. STEM highlights the epitaxial growth of Fe3O4 films on Nb:SrTiO3. Complementary polarized neutron reflectometry (PNR) and X‐ray magnetic circular dichroism (XMCD) measurements on continuous films ...

Neural network guided adjoint computations in dual weighted residual error estimation
SN Applied Sciences, 2022 In this work, we are concerned with neural network guided goal-oriented a posteriori error estimation and adaptivity using the dual weighted residual method. The primal problem is solved using classical Galerkin finite elements.

Greek-Arabic-Latin: The transmission of mathematical texts in the Middle Ages [PDF]
, 2001 During the Middle Ages many Greek mathematical and astronomical texts were translated from Greek into Arabic (ca. ninth century) and from Arabic into Latin (ca. twelfth century). There were many factors complicating the study of them, such as translation

Analysis of the total costs for variants of the Union-Find algorithm [PDF]
Discrete Mathematics & Theoretical Computer Science, 2007 We study the average behavior of variants of the UNION-FIND algorithm to maintain partitions of a finite set under the random spanning tree model. By applying the method of moments we can characterize the limiting distribution of the total costs of the ...

The one-loop spectral problem of strongly twisted N $$ \mathcal{N} $$ = 4 Super Yang-Mills theory
Journal of High Energy Physics, 2019 We investigate the one-loop spectral problem of γ-twisted, planar N $$ \mathcal{N} $$ = 4 Super Yang-Mills theory in the double-scaling limit of infinite, imaginary twist angle and vanishing Yang-Mills coupling constant.

Limit laws for a class of diminishing urn models. [PDF]
Discrete Mathematics & Theoretical Computer Science, 2007 In this work we analyze a class of diminishing 2×2 Pólya-Eggenberger urn models with ball replacement matrix M given by $M= \binom{ -a \,0}{c -d}, a,d∈\mathbb{N}$ and $c∈\mathbb{N} _0$.

Characterization of Rare Events in Molecular Dynamics
Entropy, 2013 A good deal of molecular dynamics simulations aims at predicting and quantifying rare events, such as the folding of a protein or a phase transition. Simulating rare events is often prohibitive, especially if the equations of motion are high-dimensional,

Label-based parameters in increasing trees [PDF]
Discrete Mathematics & Theoretical Computer Science, 2006 Grown simple families of increasing trees are a subclass of increasing trees, which can be constructed by an insertion process. Three such tree families contained in the grown simple families of increasing trees are of particular interest: $\textit ...

Real wave propagation in the isotropic relaxed micromorphic model [PDF]
, 2016 For the recently introduced isotropic relaxed micromorphic generalized continuum model, we show that under the assumption of positive definite energy, planar harmonic waves have real velocity.

Enumerating alternating tree families [PDF]
Discrete Mathematics & Theoretical Computer Science, 2008 We study two enumeration problems for $\textit{up-down alternating trees}$, i.e., rooted labelled trees $T$, where the labels $ v_1, v_2, v_3, \ldots$ on every path starting at the root of $T$ satisfy $v_1 < v_2 > v_3 < v_4 > \cdots$.
