Trek-Based Parameter Identification for Linear Causal Models With Arbitrarily Structured Latent Variables
We develop a criterion to certify whether causal effects are identifiable in linear structural equation models with latent variables. Linear structural equation models correspond to directed graphs whose nodes represent the random variables of interest and whose edges are weighted with linear coefficients that correspond to direct causal effects. In contrast to previous identification methods, we do not restrict ourselves to settings where the latent variables constitute independent latent fact…

Rubidium Abundances in Cool Giants from High-Resolution H-band Spectra: A New Diagnostic for Galactic Chemical Evolution
The Galactic Center and inner disk of the Milky Way contain complex stellar populations obscured by heavy dust extinction. To study their chemical composition, high-resolution near-infrared (near-IR) spectroscopy is necessary. Expanding the set of elements measurable in the near-IR, especially neutron-capture elements, improves our ability to trace nucleosynthesis and Galactic chemical evolution. This work aims to identify and characterize a spectral line suitable for determining rubidium (Rb) …

Comment on Decidability of Quasi-Dense Modal Logics by Lyon and Ostropolski-Nalewaja
In \cite{Lyon24} the question of the decidability of quasi-dense modal logics is answered, and an upper bound in EXPSPACE is given. Unfortunately, authors' intricate proof contains a major flaw that cannot be fixed, leaving the question wide open. Once identified, this error roughly amounts to assuming that the union of two consistent sets is consistent, which is of course wrong.

Identification of RIS-Assisted Paths for Wireless Integrated Sensing and Communication
Distinguishing between reconfigurable intelligent surface (RIS) assisted paths and non-line-of-sight (NLOS) paths is a fundamental problem for RIS-assisted integrated sensing and communication. In this work, we propose a pattern alternation scheme for the RIS response that uses part of the RIS as a dynamic part to modulate the estimated channel power, which can considerably help the user equipments (UEs) to identify the RIS-assisted paths. Under such a dynamic setup, we formulate the detection …

Whole-Person Education for AI Engineers
This autoethnographic study explores the need for interdisciplinary education spanning both technical and philosophical skills - as such, this study leverages whole-person education as a theoretical approach needed in AI engineering education to address the limitations of current paradigms that prioritize technical expertise over ethical and societal considerations. Drawing on a collaborative autoethnography approach of fourteen diverse stakeholders, the study identifies key motivations driving…

Statistical Analysis of Early Spectra in Type II and IIb Supernovae
We present a comprehensive analysis of the early spectra of type II and type IIb supernovae (SNe) to explore their diversity and distinguishable characteristics. Using 866 publicly available spectra from 393 SNe, 407 from type IIb SNe (SNe IIb) and 459 from type II SNe (SNe II), we analysed H$α$ and He~I 5876 A at early phases ($<40$ days from the explosion) to identify possible differences between these two SN types. By comparing the pseudo-equivalent width (pEW) and full width at half maximu…

Estado del clima en Jalisco: temporada de lluvias y comportamiento extremo de la temperatura en 2024
This article analyzes the characteristics of the rainy season and extreme temperatures recorded in the state of Jalisco, Mexico, during 2024. Using ERA5 and CHIRPS reanalysis data and observations from thirteen meteorological stations, patterns of precipitation and temperature anomalies were identified. The results show a late start and early end of the rainy season, with positive anomalies in the central and southern regions, and significant deficits in the coastal strip. Furthermore, 2024 sto…

Modified wave operators for the defocusing cubic nonlinear Schrödinger equation in one space dimension with large scattering data
In the present paper, we construct modified wave operators for the defocusing cubic nonlinear Schrödinger equation (NLS) in one space dimension without size restriction on scattering data. In the proof, we introduce a new formulation of the problem based on the linearization of the NLS around a prescribed asymptotic profile. For the linearized equation which is a system of Schrödinger equations with non-symmetric, time-dependent long-range potentials, we show a modified energy identity, as we…

You Are What You Say: Exploiting Linguistic Content for VoicePrivacy Attacks
Speaker anonymization systems hide the identity of speakers while preserving other information such as linguistic content and emotions. To evaluate their privacy benefits, attacks in the form of automatic speaker verification (ASV) systems are employed. In this study, we assess the impact of intra-speaker linguistic content similarity in the attacker training and evaluation datasets, by adapting BERT, a language model, as an ASV system. On the VoicePrivacy Attacker Challenge datasets, our metho…
