Background Pulsed field ablation (PFA) using a pentaspline catheter is increasingly applied for pulmonary vein (PV) isolation, but standardized methods to assess durable lesion formation are lacking. Objective We aimed to investigate the impact of incremental PFA applications on electrogram (EGM) characteristics and determine whether EGM signatures serve as markers for effective lesions. Methods PV EGMs of a cohort of consecutive patients were analyzed before and after single, double, and quadruple PFA appl

The objective of this PhD thesis is to develop a microfluidic chip platform for real-time, multidimensional characterization of biological samples and, eventually, calorimetric measurements at the single-entity level. The developed devices are piezoelectrically transduced single- and double-clamped beams with embedded microchannels, commonly known as Suspended Microchannel Resonators (SMRs). Their operating principle relies on the flow of samples through the microchannels and on the real-time monitoring of

As modern engineered systems grow increasingly complex and access to measurement data becomes ubiquitous, direct data-driven controller synthesis has emerged as a compelling alternative to conventional model-based approaches. This thesis presents a comprehensive data-driven framework for robust controller synthesis that leverages frequency-domain data, eliminating the need for explicit parametric modelling. A key challenge in robust controller synthesis is the quantification of uncertainty, particularly in

We derive generalization and excess risk bounds for neural nets using a\nfamily of complexity measures based on a multilevel relative entropy. The\nbounds are obtained by introducing the notion of generated hierarchical\ncoverings of neural nets and by using the technique of chaining mutual\ninformation introduced in Asadi et al. NeurIPS'18. The resulting bounds are\nalgorithm-dependent and exploit the multilevel structure of neural nets. This,\nin turn, leads to an empirical risk minimization problem with

PURPOSE: Dipole antennas that provide high transmit field penetration with large coverage, and their use in a parallel transmit setup, may be advantageous in minimizing B 1+ -field inhomogeneities at ultra-high field, i.e 7T. We have developed and evaluate ...

The goal of this special issue is to document and highlight recent progress in robot learning for human–robot collaboration (HRC), covering a diversity of articles that reflect the state-of-the-art in the field. Following an open call for papers, we receiv ...

During the last three decades, reconfigurable logic has been growing steadily and can now be found in many different fields. Field programmable gate arrays (FPGAs) are one of the most famous architecture families of reconfigurable devices. FPGAs can be seen as arrays of logic units that can be reconfigured to realize any digital systems. Their high versatility has enabled designers to drastically reduce time to market, and made FPGAs suitable for prototyping or small production series in many branch

Purpose: To describe a new type of stent consisting of a 3-dimensional (3D) braided tube made of 2 interconnected layers without any covering to treat a renal artery aneurysm. ...

The use of electron energy loss spectroscopy (EELS) in determining the electronic properties of Si and thickness dependent loss function of Si with 0.14 eV energy resolution were investigated. The dielectric response function was used to describe the interaction of a transmitted electron beam with the solid specimen. The specimen was oxidized in air for several days so that a thin amorphous SiO2 layer was formed covering both surfaces. It was observed that for fine structure investigations a high energy res

The purpose of this paper is to explore the concept of localization, which comes from homotopy theory, in the context of finite simple groups. We give an easy criterion for a finite simple group to be a localization of some simple subgroup and we apply it in various cases. Iterating this process allows us to connect many simple groups by a sequence of localizations. We prove that all sporadic simple groups (except possibly the Monster) and several groups of Lie type are connected to alternating groups. The

Precise control of the shape and position of double-null divertor configurations in the TCV tokamak has been used to trigger reliably the transition from ELM-free to ELMy ohmic H mode and back. Preprogrammed modulation of the magnetic axis height (+/- 1.25 cm), with fixed shaping field, caused the plasma to evolve, during a single discharge, between double-null-upper, double-null and double-null-lower configurations, with the secondary X point remaining close to the separatrix. The transition from ELM-free
