Identification of rock bolt length in situ conditions

open access: yesDiagnostyka, 2021
A rock bolt which is grouted into the rock strata may not be installed according to the assumed project. It concerns also cases where due to practical reasons it is impossible to drill a hole with a sufficient deepness. The consequence of that is that it

Computation and visualization of photonic quasicrystal spectra via Blochs theorem

open access: yes, 2008
Previous methods for determining photonic quasicrystal (PQC) spectra have relied on the use of large supercells to compute the eigenfrequencies and/or local density of states (LDOS).

Patient health questionnaire in the general population sample - establishing the cut-off score for detecting major depression

open access: yesEuropean Psychiatry, 2023
Introduction The traditional Patient Health Questionnaire (PHQ-9) cut-off score of ≥10 has been found to balance best sensitivity and specificity when used in patient populations.

Jordan algebras over icosahedral cut-and-project quasicrystals

open access: yes, 2023
In this paper we present a general setting for aperiodic Jordan algebras arising from icosahedral quasicrystals that are obtainable as model sets of a cut-and-project scheme with a convex acceptance window. In these hypothesis, we show the existence of an aperiodic Jordan algebra structure whose generators are in one-to-one correspondence with elements

From omics to AI—mapping the pathogenic pathways in type 2 diabetes

open access: yesFEBS Letters, EarlyView.
Integrating multi‐omics data with AI‐based modelling (unsupervised and supervised machine learning) identify optimal patient clusters, informing AI‐driven accurate risk stratification. Digital twins simulate individual trajectories in real time, guiding precision medicine by matching patients to targeted therapies.

Topological Equivalence between the Fibonacci Quasicrystal and the Harper Model

open access: yes, 2012
One-dimensional quasiperiodic systems, such as the Harper model and the Fibonacci quasicrystal, have long been the focus of extensive theoretical and experimental research. Recently, the Harper model was found to be topologically nontrivial.

Self-Matching Properties of Beatty Sequences

open access: yesActa Polytechnica, 2007
We study the selfmatching properties of Beatty sequences, in particular of the graph of the function  ⌊ jβ ⌋ against j for every quadratic unit βϵ (0,1). We show that translation in the argument by an element Gi of a generalized Fibonacci sequence almost
