Latent Variable Autoregression with Exogenous Inputs
This paper introduces a new least squares regression methodology called (C)LARX: a (constrained) latent variable autoregressive model with exogenous inputs. Two additional contributions are made as a side effect: First, a new matrix operator is introduced for matrices and vectors with blocks along one dimension; Second, a new latent variable regression (LVR) framework is proposed for economics and finance. The empirical section examines how well the stock market predicts real economic activity …

Der Signature Move für Wissenschaft ist keineswegs nackt aus der Wanne Springen und „εὕρηκα!“ rufen, sondern eher „interessant!?!“ rufen, wenn ein unerwartetes exogenes Ereignis dir gerade die Haare abgefackelt hat.

EDEN: Entorhinal Driven Egocentric Navigation Toward Robotic Deployment
Deep reinforcement learning agents are often fragile while humans remain adaptive and flexible to varying scenarios. To bridge this gap, we present EDEN, a biologically inspired navigation framework that integrates learned entorhinal-like grid cell representations and reinforcement learning to enable autonomous navigation. Inspired by the mammalian entorhinal-hippocampal system, EDEN allows agents to perform path integration and vector-based navigation using visual and motion sensor data. At th…

Equisingular lifting of semi-log canonical $F$-split $K$-trivial surfaces
We show that a projective globally $F$-split semi-log canonical $K$-trivial surface over an algebraically closed field of characteristic $p>2$ admits an equisingular lifting over the ring of Witt vectors.

Ich lese gerade das Buch "Unsere Welt neu denken" von #MajaGöpel und bin an der Stelle, an der sie ihre Berührungspunkte mit #Volkswirtschaftslehre und #Wirtschaftswissenschaften beschreibt, insbesondere die abstrusen Theorien, mit denen diese Zweige arbeiten (Kapitel "Mensch und Verhalten"). Mensch und Umwelt kommen darin nicht vor. Geld ist die einzige Messgröße, auf die es ankommt und es wird vom absoluten Egoismus ausgegangen, der dann auf unerklärliche Weise letzten Endes doch wieder allen zugute kommen soll.
Mich wundert es nicht mehr, wieso wir alle so kaputtgemanaget und -regiert werden, wenn diese Leute nichts anderes als erfundene Fakten gelehrt bekommen. Die glauben wahrscheinlich sogar, dass sie richtig handeln.

A priori bounds and equicontinuity of orbits for the intermediate long wave equation
We prove uniform-in-time a priori $H^s$ bounds for solutions to the intermediate long wave equation posed both on the line and on the circle, covering the range $-\frac12

Exocomets of $β$ Pictoris I: Exocomet destruction, sodium and disk line variability in 17 years of HARPS observations
The young $β$ Pictoris system has been monitored with high-resolution optical spectrographs for decades. These observations have revealed strongly variable absorption in the Ca II H\&K lines attributed to in-falling cometary bodies. Since 2003, over 9000 HARPS observations of $β$ Pictoris have been taken and many of these have not yet been used for exocomet studies. We search these spectra for new exocomet phenomenology enabled by the long time coverage and large volume of this dataset. We sy…
