Detection of Fe and Ti on the dayside of the ultrahot Jupiter MASCARA-1b with CARMENES
Ultrahot Jupiters are a type of gaseous exoplanet that orbit extremely close to their host star, resulting in significantly high equilibrium temperatures. In recent years, high-resolution emission spectroscopy has been broadly employed in observing the atmospheres of ultrahot Jupiters. We used the CARMENES spectrograph to observe the high-resolution spectra of the dayside hemisphere of MASCARA-1b in both visible and near-infrared. Through cross-correlation analysis, we detected signals of \ion{…

TimeXer: Empowering Transformers for Time Series Forecasting with Exogenous Variables
Recent studies have demonstrated remarkable performance in time series forecasting. However, due to the partially-observed nature of real-world applications, solely focusing on the target of interest, so-called endogenous variables, is usually insufficient to guarantee accurate forecasting. Notably, a system is often recorded into multiple variables, where the exogenous series can provide valuable external information for endogenous variables. Thus, unlike prior well-established multivariate or…

Chiral-induced unidirectional spin-to-charge conversion
The observation of spin-dependent transmission of electrons through chiral molecules has led to the discovery of chiral-induced spin selectivity (CISS). The remarkably high efficiency of the spin polarizing effect has recently gained significant interest due to the high potential for novel sustainable hybrid chiral molecule magnetic applications. However, the fundamental mechanisms underlying the chiral-induced phenomena remain to be understood fully. In this work, we explore the impact of chir…

Probing Two-body Bound States in the Continuum and Nonlinear Breathers Using Intensity Correlations
We study Hanbury Brown-Twiss spatial intensity correlations in femtosecond laser-fabricated photonic Su-Schrieffer-Heeger lattices. We first probe edge bound states in the continuum (BICs) of two indistinguishable bosons by mapping the intensity correlations to the two-body bosonic quantum walk. These two-body edge BICs show remarkable robustness in the presence of disorder. The localization of intensity correlation, observed in the linear regime, persists at weak nonlinearity due to the format…

X-Shooting ULLYSES: Massive Stars at low metallicity II. DR1: Advanced optical data products for the Magellanic Clouds
Using the medium resolution spectrograph X-shooter, spectra of 235 OB and Wolf-Rayet (WR) stars in sub-solar metallicity environments have been secured. [...]This second paper focuses on the optical observations of 232 Magellanic Clouds targets. It describes the uniform reduction of the UVB (300 - 560 nm) and VIS (550 - 1020 nm) XShootU data as well as the preparation of advanced data products [...] . The data reduction of the raw data is based on the ESO CPL X-shooter pipeline. We paid particu…

Cowboys’ Mike McCarthy Speaks Out Amid Hot Seat Rumors
The Dallas Cowboys have experienced significant changes this offseason, including the departure of veteran players and key coaching staff members. Despite these transitions, head coach Mike McCarthy appears confident in the team’s direction as the 2024 NFL Draft approaches. Addressing concerns about his contract status, McCarthy reassured observers that he remains focused on the franchise’s goals. “Don’t feel bad for me. I’m in a great spot. … I know you care. I know you care.” He…

Some observations on a result by Bialinicki-Birula and Zelazko
We are interested in investigating some definitions and assumptions stated in [4], in particular the notions of measurability and atomicity that the two authors used in order to give a representation for multiplicative linear functionals (m.l.f. so on) over the cartesian product of algebras. We want to briefly analyze the result under other strong proper axioms with respect to ZF(C). Some little historical and notational remarks will be given.

Good Morning #Canada
Happy Bithday to Martin Hayter Short, born March 26, 1950, one of Canada's and finest comedians. Thankfully, his career as a social worker never developed and he was sucked into the entertainment industry. He has been awarded two Primetime Emmy Awards, a Tony Award and an Officer of the Order of Canada in 2019. I must say... a remarkable career.

Multifractal Formalism from Large Deviations
It has often been observed that the Multifractal Formalism and the Large Deviation Principles are intimately related. In fact, Multifractal Formalism was heuristically derived using the Large Deviations ideas. In numerous examples in which the multifractal results have been rigorously established, the corresponding Large Deviation results are valid as well. Moreover, the proofs of multifractal and large deviations are remarkably similar. The natural question then is whether under which conditio…

Topological flat bands, valley polarization, and interband superconductivity in magic-angle twisted bilayer graphene with proximitized spin-orbit couplings
We study theoretically the magic-angle twisted bilayer graphene with proximity-induced Ising and Rashba spin-orbit couplings on the top layer. We demonstrate topological flat bands and identify three distinct topological phases. Using a weak coupling analysis, we find that (partial) valley polarization prevails for a wide range of doping, suppressing the usual superconductivity with a pairing between time-reversal partners. Remarkably, we uncover that observable unconventional intervalley inter…
