The Laser Interferometer Space Antenna (LISA) will observe gravitational waves in the millihertz frequency band, detecting signals from a vast number of astrophysical sources embedded in instrumental noise. Extracting individual signals from these overlapping contributions is a fundamental challenge in LISA data analysis and is traditionally addressed using computationally expensive stochastic Bayesian techniques. In this work, we present ...

Background: People with cancer often experience stress. Digital health interventions (DHIs) can help individuals increase momentary relaxation. Breeze is a gamified breathing training that can be embedded into DHIs. Its effectiveness in controlled cross-sectional studies was shown. However, adherence to Breeze and its effect on momentary relaxation in longitudinal interventional studies has yet to be investigated. Objective: This work ...

This paper provides a general framework for deriving effective material properties of time-modulated systems of subwavelength resonators. It applies to subwavelength resonator systems with a general form of time-dependent parameters. We show that the resonators can be accurately described by a point-scattering formulation when the width of the resonators is small. In contrast to the static setting, where this point interaction approximation ...
