Aim: Accurate prediction of respiratory motion is essential for bridging imaging latencies for active motion management in external beam radiotherapy. Deep learning approaches, such as long short-term memory (LSTM) networks, have shown promising performance, but their data requirements and generalizability across institutions remain unclear. In the context of radiotherapy surface imaging,...

Extracting waveforms from electrocardiography (ECG) printouts remains a difficult task even today. A recent challenge organized by Physionet highlights the need for practical solutions which could give access to billions of ECGs globally stored in image formats. A key limitation of the Physionet challenge is its focus on a single fixed layout (3x4 matrix), which does not reflect the variety...

Introduction
Dyskalemia, encompassing hyperkalemia (K⁺ ≥ 5.5 mEq/L) and hypokalemia (K⁺ ≤ 3.5 mEq/L), is a frequent electrolyte disorder with potentially fatal cardiac consequences, requiring timely monitoring. While diagnosis depends on invasive and time-consuming blood tests, the strong influence of serum K⁺ on ECG morphology enables ECG-based assessment. To overcome the limited...

Hintergrund und Zielstellung:
Die Anpassung von Hörgeräten oder Hörimplantaten erfordert die Einstellung des elektrischen Stimulationsbereichs. In der klinischen Praxis basiert diese in der Regel auf subjektiven Angaben der Patienten zur wahrgenommenen Lautheit der Reize. Diese Rückmeldungen sind jedoch nicht immer zuverlässig, insbesondere bei Patientengruppen mit eingeschränkter...

Introduction
The effects of anti-cancer drugs on 3D spheroids can be assessed using electrical impedance spectroscopy (EIS) performed on microelectrode arrays (MEAs). However, in planar MEAs, the solid substrate limits nutrient diffusion to the bottom of the spheroids. In addition, spheroid placement and stabilization on planar MEAs are challenging. To overcome these limitations, mesh MEAs...

Introduction
The transmembrane potential (Vm) is a fundamental bioelectric property of cells that plays an active role in regulating cell proliferation, differentiation, and tissue organization. There is increasing evidence that alterations in Vm are not merely consequences of malignant transformation, but rather, they function as upstream regulators of cancer initiation, progression, and...

Background
Uveal melanomas and adjacent organs at risk (OARs) represent some of the smallest and most challenging structures to depict and define in radiotherapy. Historically, dedicated ocular proton therapy centers have used a geometrical model-based planning approach for target definition to effectively utilize their sharp beam penumbras. This work presents a workflow to integrate...

Goal
In carbon-ion radiotherapy (CIRT), the prescribed RBE-weighted dose depends on the clinical RBE model in use. Differences between the LEM1- and mMKM-based dose systems make it difficult to directly compare treatment plans, reported doses, and clinical experience across centres. This study introduces an LETd-based framework that links RBE differences between these dose systems and...

Mathematical representations of voltage-gated ion channels are fundamental to in silico electrophysiology. Personalization remains constrained by model complexity, parameter identifiability, and the experimental effort required to calibrate mechanistic gating schemes. Traditional methodologies—the Hodgkin–Huxley (HH) and Markov (hidden Markov model, HMM) formalisms—balance computational...

Introduction
Computer simulations are widely used for studying bioelectric activity of the nervous system. Modelling body surface distributions of compound nerve action potentials (CNAPs) is computationally challenging due to the complex nerve structure containing thousands of axons. Previously, we proposed a two-domain model for reduc-ing computational load, that contained the passive...

Introduction
In particle therapy the biological absorbed dose ist the product of physical dose and relative biological effectiveness (RBE). For carbon ions, RBE can be derived using either the Local Effect Model-I (LEM-I) or the modified Microdosi-metric Kinetic Model (mMKM). Our clinic uses a bi-model approach, prescribing and optimizing doses in LEM-I, and subsequent mMKM recalculation may...

The evaluation of performance for continuous cursor control brain-computer interfaces (BCIs) is problematic especially in motor-impaired patients. For such patients, a movement trajectory cannot be evaluated with regards to a ground truth, since they oftentimes cannot volitionally move their muscles.

Introduction (14 pt bold)
Surface guided radiation therapy (SGRT) is routinely used for patient positioning and intrafractional motion monitor-ing. In clinical practice, however, surface scanner systems are commonly reduced to rigid transformations or region-of-interest–based metrics, while the full three-dimensional (3D) sur-face information remains largely unused. In parallel, thermal...
