A Regularized Riccati Recursion for Interior-Point Optimal Control
We derive a closed-form extension of Riccati's recursion for solving regularized LQR problems. We also show how this can be used to solve general constrained, non-convex, discrete-time optimal control problems via a regularized interior point method, while guaranteeing that each step is a descent direction of an Augmented Barrier-Lagrangian merit function. We also provide MIT-licensed implementations of our method in C++ and JAX.

Die Mehrheit der Hamburger Bevölkerung hat sich gegen den Modellversuch zum #Grundeinkommen ausgesprochen.
62,6 Prozent lehnten das Vorhaben ab, das 2000 Personen drei Jahre lang ein monatliches Einkommen sichern sollte.
Politischer Rückhalt kam lediglich von der #Linken. Kritisie…

62 Prozent stimmen dagegen: Hamburger verwerfen Modellversuch zum Grundeinkommen
Das Experiment "Hamburg testet Grundeinkommen" fällt aus. Das Votum der Bürger war deutlich: Fast zwei Drittel der Bürger stimmen dagegen. Außer der Linken stellten sich alle Fraktionen der Bürgerschaft gegen das Modellprojekt.

Triple-strangeness hidden-charm pentaquarks
We investigate the possible existence of triple-strangeness hidden-charm pentaquark states in the off-shell coupled-channel formalism. The open-charm meson-baryon $\bar{D}_sΩ_c$, $\bar{D}_sΩ_c^*$, $\bar{D}_s^*Ω_c$, and $\bar{D}_s^*Ω_c^*$ channels are considered, together with the hidden-charm $J/ψΩ$ channel. The two-body kernel Feynman amplitudes are constructed from an effective Lagrangian based on hidden local symmetry and heavy-quark spin symmetry. The coupled Blankenbecler-Sugar equat…

Mehr Klimaschutz: Hamburger stimmen für "Zukunftsentscheid"
Hamburg soll fünf Jahre früher als bislang geplant klimaneutral werden - nämlich bereits 2040. Beim "Hamburger Zukunftsentscheid" hat sich dafür die Mehrheit der Hamburgerinnen und Hamburger ausgesprochen, die ihre Stimme abgegeben haben.

Visual morphological classification of the full MaNGA DR17 sample: a general characterization
We present the MaNGA Visual Morphology (MVM) catalogue, featuring a visual morphological classification of 10,059 galaxies in the final MaNGA sample. By combining SDSS and DESI Legacy Survey (DLS) images, we classified galaxies into 13 Hubble types, detected tidal features, categorized bars into different families, and estimated concentration, asymmetry, and clumpiness. The depth of the DLS images allowed us to identify structural details that were not evident in the SDSS images, resulting in a…

Euclid preparation. Cosmology Likelihood for Observables in Euclid (CLOE). 6: Impact of systematic uncertainties on the cosmological analysis
Extracting cosmological information from the Euclid galaxy survey will require modelling numerous systematic effects during the inference process. This implies varying a large number of nuisance parameters, which have to be marginalised over before reporting the constraints on the cosmological parameters. This is a delicate process, especially with such a large parameter space, which could result in biased cosmological results. In this work, we study the impact of different choices for modellin…

Environmental Regulation of Dust and Star Formation Unveiled by Subaru Dual Narrow-band Imaging: Degree-scale Balmer Decrement Mapping across a z = 0.9 Supercluster
We present results from a dual narrow-band imaging survey targeting the CL1604 supercluster at z = 0.9 using the Subaru Telescope. By combining the NB921 filter on HSC and the NB1244 filter on SWIMS, we can detect redshifted H$α$ and H$β$ emission lines from the supercluster. This unique technique allows us to measure both star formation rates and dust extinction for a sample of 94 emission-line galaxies across the supercluster. We find that dust extinction, estimated from the Balmer decremen…

Cosmology Likelihood for Observables in \Euclid (CLOE). 1. Theoretical recipe
As the statistical precision of cosmological measurements increases, the accuracy of the theoretical description of these measurements needs to increase correspondingly in order to infer the underlying cosmology that governs the Universe. To this end, we have created the Cosmology Likelihood for Observables in Euclid (CLOE), which is a novel cosmological parameter inference pipeline developed within the Euclid Consortium to translate measurements and covariances into cosmological parameter cons…
