MTRec: Learning to Align with User Preferences via Mental Reward Models
Recommendation models are predominantly trained using implicit user feedback, since explicit feedback is often costly to obtain. However, implicit feedback, such as clicks, does not always reflect users' real preferences. For example, a user might click on a news article because of its attractive headline, but end up feeling uncomfortable after reading the content. In the absence of explicit feedback, such erroneous implicit signals may severely mislead recommender systems. In this paper, we pr…

Almost paracontact metric 3-dimensional Walker manifolds
In this paper we construct and study almost paracontact metric structures $(φ,ξ,η,g)$ on a 3-dimensional Walker manifold $(M,g)$ with respect to a local basis only by the coordinate functions of a unit space-like vector field $ξ$, globally defined on $M$ and a function $f$ on $M$, characterizing the Lorentzian metric $g$. Necessary and sufficient conditions are obtained for $M$, endowed with these structures, to fall in one of the following classes of 3-dimensional almost paracontact metric…

Electromagnetic Formation Flying Using Alternating Magnetic Field Forces and Control Barrier Functions for State and Input Constraints
This article presents a feedback control algorithm for electromagnetic formation flying with constraints on the satellites' states and control inputs. The algorithm combines several key techniques. First, we use alternating magnetic field forces to decouple the electromagnetic forces between each pair of satellites in the formation. Each satellite's electromagnetic actuation system is driven by a sum of amplitude-modulated sinusoids, where amplitudes are controlled in order to prescribe the tim…

Ionizing Radiation Escape from Low-Redshift Galaxies and Its Connection to Cosmic Reionization
The escape of Lyman continuum (LyC) radiation from early galaxies transformed the intergalactic medium (IGM) and is intimately connected to the fueling and feedback processes that regulate galaxy evolution. IGM attenuation interferes with high-redshift LyC observations, but growing samples of LyC observations at z<0.1 are revealing the properties of LyC-emitting galaxies. Along with multi-wavelength observations of nearby LyC-emitting candidates, cosmological simulations, and simulations of LyC…

Fractional topological insulators at odd-integer filling: Phase diagram of two-valley quantum Hall model
The fractional quantum Hall effect has recently been shown to exist in heterostructures of van der Waals materials without an externally applied magnetic field, e.g. in twisted bilayers of MoTe$_2$. These fractional Chern insulators break time-reversal symmetry spontaneously through polarization of the electron spins in a quantum spin Hall insulator band structure with flat bands. This prompts the question, which states could be realized if the spins remain unpolarized or polarize partially. Sp…

New gear has been acquired 😁.
I thought about filling the gap between soft(er) trekking shoes and very stiff mountain boots since ages.
I'm curious about the next steps.. Literally.

I’ve been getting beta reader feedback on my #novel and it’s the most magical thing hearing how other people have formed their own relationships to and feelings towards my characters.
I made up these characters in my own mind, they didn’t exist a few months ago, and now they are real to not just me but other living, breathing humans.
Artistic creation feels like one of the closest ways we have of approaching a sense of something almost divine.
