Federated Learning for surgical vision in appendicitis classification: Results of the FedSurg EndoVis 2024 challenge

Max Kirchner · Hanna Hoffmann · Alexander C. Jenke · Oliver L. Saldanha · y 15 más

Developing generalizable surgical AI requires multi-institutional data, yet privacy constraints preclude direct data sharing, making Federated Learning (FL) a natural candidate. Its application to complex, spatiotemporal surgical video remains largely unbenchmarked. We present the FedSurg Challenge, the first internati...

A stabilized unfitted space-time finite element method for parabolic problems on moving domains

Ruizhi Wang · Weibing Deng

This paper presents a space-time finite element method (FEM) based on an unfitted mesh for solving parabolic problems on moving domains. Unlike other unfitted space-time finite element approaches that commonly employ the discontinuous Galerkin (DG) method for time-stepping, the proposed method employs a fully coupled s...

Local order and phonon dynamics in olivine at high temperatures

Daniel CHANEY · Benjamin FAHL · Erik NEUMANN · Christin WIGGERS · y 1 más

We aim to study temperature dependent local order phenomena and their influence on the phonon diffuse scattering in the mineral olivine. Olivine forms a solid solution series with two symmetry independent metal cation sites. It was proposed in literature, that the thermal history of the sample significantly influences...

Solubility enhancing solid dispersion of the model PROTAC® MS4078 – the key to bioavailability enhancement?

Nicole Simmat-Hofmann · Florian Johann · Heide Marika Duevel · Meike Harms · y 1 más

Bifunctional degraders – commonly known as PROTACs® – are promising new therapeutic modalities, that broaden the druggable protein spectrum and offer new therapeutic strategies for cancer and other widespread diseases. Due to their size and unfavorable physicochemical properties, solubility and permeability are challen...

High-temperature structural phase transitions in pure and Al, Ga and Fe substituted Li7La3Zr2O12 garnet-type solide state electrolyte materi

Guenther REDHAMMER · Daniel RETTENWANDER (ORCID: 0000-0002-2074-941X) · Chloe FULLER · QUOC HUNG NGUYEN · y 1 más

Substituted Li7La3Zr2O12 (LLZO) is a highly prospective material for application as a solid electrolyte in solid-state batteries due its high Li-ion conductivity. With Al3+ a cubic Ia-3d garnet structure is stabilized, small amounts of Ga3+ or Fe3+ stabilize an I-43d structure. Ga-LLZO and Fe-LLZO show phase transition...

Investigation of aggregation kinetics, transient and metastable states of lipid-based nanosystems as drug delivery vectors for treatment of

Ilaria CLEMENTE · Luigi TALARICO · Giulia GABBRICCI · Gouranga MANNA

The development of effective and targeted drug delivery systems for therapeutics and diagnostics is a challenging matter. Lipid-based nanocarriers are emerging as optimal candidates to achieve enhanced control over drug release, target selectivity and biocompatibility, thus resulting in improved pharmacokinetic profile...

Active learning strategy for excursion-set confidence regions of functional simulator outputs

Brunel, Lucas · Balesdent, Mathieu · Brevault, Loïc · Le Riche, Rodolphe · y 1 más

Estimating excursion set confidence regions seeks to identify regions where a function may exceed some threshold with a given confidence level. This paper focuses on estimating such confidence regions in cases where the function has random inputs and a functional output that is returned all at once. We develop a surrog...

A height-based metaconcept for rooted tree balance and its implications for the B1 index

Fischer, Mareike · Hamann, Tom Niklas · Wicke, Kristina

Tree balance has received considerable attention in recent years, both in phylogenetics and in other areas. Numerous (im)balance indices have been proposed to quantify the (im)balance of rooted trees. A recent comprehensive survey summarized this literature and showed that many existing indices are based on similar und...
