Edge-On Disk Study (EODS) II: Thermal Structure of the Flying Saucer Disk
Context. The dust and gas temperature in proto-planetary disks play critical roles in determining their chemical evolution and influencing planet formation processes. Aims. We attempted an accurate measurement of the dust and CO temperature profile in the edge-on disk of the Flying Saucer. Methods. We used the unique properties of the Flying Saucer, its edge-on geometry and its fortunate position in front of CO clouds with different brightness temperatures to provide independent constraints on …

KI-generierte Zusammenfassung von Google führt zu Gerüchten:
Vor knapp einer Woche war unser Leitungswasser wegen einer mikrobiologischen Verschmutzung nicht trinkbar. Die Bevölkerung wurde dazu aufgerufen, das Wasser abzukochen.
Nun gehen in lokalen Chats Screenshots rum, die behaupten, es wären PFAS gewesen. Die Google KI-Zusammenfassung spinnt das wohl aus einem Zeitungsartikel zusammen, in dem nebenbei über vergangene PFAS-Verunreinigungen berichtet wurde

Experimental demonstration of corrugated nanolaminate films as reflective light sails
Achieving laser-driven, reflective, relativistic light sails would represent a tremendous breakthrough for humankind, allowing us to advance our understanding of the solar system and deep space far beyond what we know from space probes, telescopes, and objects passing near Earth. Numerous sail film designs have been proposed, but none have been demonstrated that satisfy all of the stringent optical, mechanical, and mass budget constraints. Here we overcome this challenge by experimentally demon…

Clinical test cases for model-based dose calculation algorithm commissioning, QA and benchmarking, for 192Ir HDR brachytherapy of gynecologic cancers
Purpose: To develop clinically relevant test cases for commissioning Model-Based Dose Calculation Algorithms (MBDCAs) for 192Ir High Dose Rate (HDR) gynecologic brachytherapy following the workflow proposed by the TG-186 report and the WGDCAB report 372. Acquisition and Validation Methods: Two cervical cancer intracavitary HDR brachytherapy patient models were created, using either uniformly structured regions or realistic segmentation. The computed tomography (CT) images of the models were con…

Existence of normalized solutions to nonlinear Schrödinger equations with potential on lattice graphs
We study the existence of ground state normalized solution of the following Schrödinger equation: \begin{equation*} \begin{cases} -Δu+V(x)u+λu=f(x,u), & x\in\mathbb{Z}^d \\ \Vert u\Vert_2^2=a \end{cases} \end{equation*} where $V(x)$ is trapping potential or well potential, $f(x,u)$ satisfies Berestycki-Lions type condition and other suitable conditions. We show that there always exists a threshold $α\in[0,\infty)$ such that there do not exist ground state normalized solutions for $a\in (0…

Multi-messenger dynamic imaging of laser-driven shocks in water using a plasma wakefield accelerator
Understanding dense matter hydrodynamics is critical for predicting plasma behavior in environments relevant to laser-driven inertial confinement fusion. Traditional diagnostic sources face limitations in brightness, spatiotemporal resolution, and inability to detect relevant electromagnetic fields. In this work, we present a dual-probe, multi-messenger laser wakefield accelerator platform combining ultrafast X-rays and relativistic electron beams at 1 Hz, to interrogate a free-flowing water ta…
