UltraTwin: Towards Cardiac Anatomical Twin Generation from Multi-view 2D Ultrasound
Echocardiography is routine for cardiac examination. However, 2D ultrasound (US) struggles with accurate metric calculation and direct observation of 3D cardiac structures. Moreover, 3D US is limited by low resolution, small field of view and scarce availability in practice. Constructing the cardiac anatomical twin from 2D images is promising to provide precise treatment planning and clinical quantification. However, it remains challenging due to the rare paired data, complex structures, and US…

Ukrainischer F-16-Pilot ums Leben gekommen
Bei einem Einsatz gegen russische Luftangriffe in der Ukraine ist nach Militärangaben der Pilot eines Kampfjets vom Typ F-16 ums Leben gekommen. Der Oberstleutnant habe in der Nacht russische Angriffe abgewehrt, als der Bomber getroffen worden sei, so die Armee. Der Pilot habe selbst sieben Ziele abgeschossen und dann nach einem Treffer an seiner Maschine noch "alles getan, um sein F…

Ukraine-Liveblog: ++ Ukraine verlässt Abkommen über Minen-Verbot ++
Nach den baltischen Staaten will auch die Ukraine aus dem Abkommen zum Verbot von Antipersonenminen austreten. Auch neue Sanktionen der EU werden nach Angaben des Kreml nicht zu einem Ende Krieges gegen die Ukraine führen.

Spectral evolution of GX 17+2 using AstroSat and NICER observations
We study the spectral evolution of the Z-track source GX 17+2 using AstroSat and NICER observations taken between 2016 and 2020. The AstroSat observations cover the period when the source is in the normal branch (NB) and the flaring branch (FB), while for the NICER ones the variability can be associated with the FB branch. The source spectra at different regions of the branches are well described by accretion disk emission, blackbody surface emission and a thermal Comptonization component. In t…

A Schwarz-Jack lemma, circularly symmetric domains and numerical ranges
We prove a Schwarz-Jack lemma for holomorphic functions on the unit disk with the property that their maximum modulus on each circle about the origin is attained at a point on the positive real axis. With the help of this result, we establish monotonicity and convexity properties of conformal maps of circularly symmetric and bi-circularly symmetric domains. As an application, we give a new proof of Crouzeix's theorem that the numerical range of any $2\times 2$ matrix is a $2$-spectral set for t…

Axiomatizing Rumsfeld Ignorance
In a recent paper, Kit Fine presents some striking results concerning the logical properties of (first-order) ignorance, second-order ignorance and Rumsfeld ignorance. However, Rumsfeld ignorance is definable in terms of ignorance, which makes some existing results and the axiomatization problem trivial. A main reason is that the accessibility relations for the implicit knowledge operator contained in the packaged operators of ignorance and Rumsfeld ignorance are the same. In this work, we assu…
