Iterated Function Systems in Mixed Euclidean and p-adic Spaces

open access: yes, 2006
We investigate graph-directed iterated function systems in mixed Euclidean and p-adic spaces. Hausdorff measure and Hausdorff dimension in such spaces are defined, and an upper bound for the Hausdorff dimension is obtained.

RefineCatDiff: Toward High‐Quality Medical Image Segmentation via a Categorical Diffusion Refinement Framework

open access: yesAdvanced Intelligent Systems, EarlyView.
This study proposes RefineCatDiff, a refinement framework for high‐quality medical image segmentation. By developing a categorical distribution‐based discrete diffusion process for refinement, the framework aligns well with the characteristics of image segmentation tasks. Experimental results on multiple datasets across different modalities demonstrate

How to extend Carath\'eodory's theorem to lattice-valued functionals

open access: yesResults in Nonlinear Analysis, 2020
Substituting in the definition of outer measure the addition with the maximum (or the supremum, or the join) operation we obtain a new set function called retuo measure. It is proved that every retuo measure is an outer measure.

Ribosomal Incorporation of Thioxanthone as a Noncanonical Amino Acid Facilitates the Engineering of Photoenzymes

open access: yesChemCatChem, EarlyView.
Thioxanthone is an efficient visible‐light photosensitizer and facilitates reactions that are not known from natural enzymes. It is now possible to incorporate thioxanthone as a noncanonical amino acid (thioX) into proteins by an engineered amino acyl tRNA synthetase.

On the Billingsley dimension of Birkhoff average in the countable symbolic space

open access: yesComptes Rendus. Mathématique, 2020
We compute a lower bound of Billingsley–Hausdorff dimension, defined by Gibbs measure, of the level set related to Birkhoff average in the countable symbolic space $\mathbb{N}^{\mathbb{N}}$.

Plasma Diffuse Reflectance Infrared Fourier Transform Spectroscopy Cell Design and Experimental Set‐Up for Operando‐DRIFTS Investigations on Plasma‐Induced Heterogeneous Catalyzed Reactions

open access: yesChemistry–Methods, EarlyView.
A customized apparatus for operando plasma‐diffuse reflectance infrared Fourier transform spectroscopy is developed by modifying the dome of a commercially available Harrick reaction chamber. The designed high‐voltage electrode is mounted and attached within a cylindrical holder made of PEEK.

Selective Modification of the Product Profile of Biocatalytic Hydrolyzed PET via Product‐Specific Medium Engineering

open access: yesChemSusChem, Volume 18, Issue 6, March 15, 2025.
The product profile of enzymatically hydrolyzed PET can be modified by medium engineering and thereby adapted to a desired product. TPA, MHET or BHET can be forced as the predominant product using a basic pH (blue), 25 % ethylene glycol (EG) and IsPETasewt (green) or ≥25 % EG and LCCICCG (pink), respectively.

Deep Learning Pipeline for Automated Assessment of Distances Between Tonsillar Tumors and the Internal Carotid Artery

open access: yesHead &Neck, EarlyView.
ABSTRACT Background Evaluating the minimum distance (dTICA) between the internal carotid artery (ICA) and tonsillar tumors (TT) on imaging is essential for preoperative planning; we propose a tool to automatically extract dTICA. Methods CT scans of 96 patients with TT were selected from the cancer imaging archive.
