The pair annihilation reaction D + D --> 0 in disordered media and conformal invariance

open access: yes, 2007
The raise and peel model describes the stochastic model of a fluctuating interface separating a substrate covered with clusters of matter of different sizes, and a rarefied gas of tiles.

Self-Affine Tilings with Several Tiles, I

open access: yesApplied and Computational Harmonic Analysis, 1999
A collection \(T_i \subseteq {\mathbb R}^d\), \(i=1, \ldots, M\), together with an expanding \(d\times d\) matrix \(A\), and a collection of sets \(\Gamma_{ij} \subseteq {\mathbb Z}^d\), \(i,j=1, \ldots, M\), is called \textit{self-affine} if \[ AT_i = \bigcup_{j=1}^M (\Gamma_{ij}+T_j), \;\;(i=1, \ldots, M) \] (the sets in the union above are assumed ...

Quantifying Spin Defect Density in hBN via Raman and Photoluminescence Analysis

open access: yesAdvanced Functional Materials, EarlyView.
An all‐optical method is presented for quantifying the density of boron vacancy spin defects in hexagonal boron nitride (hBN). By correlating Raman and photoluminescence signals with irradiation fluence, defect‐induced Raman modes are identified and established an relationship linking optical signatures to absolute defect densities. This enables direct

Bioinspired Stabilization of Fluorescent Au@SiO2 Tracers for Multimodal Biological Imaging

open access: yesAdvanced Functional Materials, EarlyView.
This study demonstrates a bioinspired stabilization strategy for fluorescent gold‐silica nanoparticles. Inspired by natural biosilica maturation, high‐temperature calcination transforms the silica shells, preventing dissolution in cell culture media and intracellular environments.

Odraz dobovej meštianskej módy na košických nálezoch kachlíc z 15. – 16. storočia

open access: yesArchaeologia Historica, 2016
Príspevok spracováva neveľký súbor kachlíc a foriem na kachlice z Košíc cez optiku dobovej módy, ktorá je na nich zobrazená. Žánrovej pestrosti motívov súboru kachľových výrobkov je nadradený hlavný predmet záujmu a tým sú odevy zobrazených postáv.

Hybrid Scaffolds Decouple Biochemical & Biophysical Regulation of Cell Phenotype

open access: yesAdvanced Healthcare Materials, EarlyView.
Replicating tissue‐specific extracellular matrix is crucial for understanding its role in disease. This work demonstrates independent control over stiffness, composition and 3D collagen architecture using hybrid scaffolds: patterned collagen perfused with defined hydrogels.

L’Anjou : la tuile au pays de l’ardoise

open access: yesArchéologie Médiévale
At the edge of both the Armorican Massif and the Paris Basin, the Anjou region is well known for its slated roofs. Though slate deposits are numerous and well stocked, other roofing materials have been used concurrently in restricted areas ...

Research on the Architecture of Phased Array Antenna of LEO Communication Satellites Based on Hybrid Beamforming

open access: yes天地一体化信息网络, 2021
Due to the characteristics of low earth orbit (LEO) communication satellite system like low propagation loss, small propagation delay and high pointing accuracy, a hybrid architecture-“analog beamforming stage and digital beamforming (DBF) stage” was ...

Approximate Self-Assembly of the Sierpinski Triangle

open access: yes, 2010
The Tile Assembly Model is a Turing universal model that Winfree introduced in order to study the nanoscale self-assembly of complex (typically aperiodic) DNA crystals.
