The investigation of 84 TESS totally eclipsing contact binaries
Based on the eclipsing binary catalog provided by \cite{2022ApJS..258...16P}, 84 totally eclipsing contact binaries with stable light curves were selected. The TESS light curves of these 84 targets were studied using the Physics Of Eclipsing Binaries code. The results indicate that there are 18 deep contact binaries, 39 moderate contact binaries, and 27 shallow contact binaries. Among them, 43 targets exhibit the O'Connell effect, which is attributed to the presence of star-spot on the componen…

Efficient Implementation of Multi-sensor Adaptive Birth Samplers for Labeled Random Finite Set Tracking
Adaptive track initiation remains a crucial component of many modern multi-target tracking systems. For labeled random finite sets multi-object filters, prior work has been established to construct a labeled multi-object birth density using measurements from multiple sensors. A naive construction of this adaptive birth set density results in an exponential number of newborn components in the number of sensors. A truncation procedure was provided that leverages a Gibbs sampler to truncate the bi…

Shortermism and excessive risk taking in optimal execution with a target performance
We deal with the optimal execution problem when the broker's goal is to reach a performance barrier avoiding a downside barrier. The performance is provided by the wealth accumulated by trading in the market, the shares detained by the broker evaluated at the market price plus a slippage cost yielding a quadratic inventory cost. Over a short horizon, this type of remuneration leads, at the same time, to a more aggressive and less risky strategy compared to the classical one, and over a long hor…

I am struggling with how to deal with very long articles on topics I'm interested about but at a different level than the author.
1. I'm acknowledging that "very long" is a "very" subjective matter. I'd say that for me that's usually what goes beyond 5min read time.
2. I'm also acknowledging that it's quite impossible to find the perfect match of the level of details provided by an article and the level of detail I'm interested.
1. If I save the article for later, I know I won't read it.
2. Many times listening to the article (using ElevenReader) provides a solution.
3. I am starting to use AI summarization more often. Not Safari's which is useless.
I don't feel quite right about this last approach.

We propose a framework to assess and report explainable AI features. Our evaluation framework for AI explainability is based on four criteria: 1) Consistency quantifies the variability of explanations to similar inputs, 2) Plausibility estimates how close the explanation is to the ground truth, 3) F…

There is no exogenously defined budget of goods to be provided.

In $1990$, Hartsfield and Ringel introduced antimagic graphs. Hartsfield and Ringel conjectured that every connected graph (and in particular, a tree) except $K_2$ is antimagic. In $2010$, Hefetz et al.\ raised two questions: Is every orientation of any simple connected undirected graph antimagic? and Given any undirected graph $G$, does there exist an orientation of $G$ which is antimagic? They call such an orientation an {\it antimagic orientation} of $G$. Recently, Bhavale provided an edge l…

The KO can also be applied to controlled dynamical systems, and the linearity of the KO then facilitates analysis and control calculations. In principle, the potential benefits provided by the KO, and the way that it facilitates th…

Rota-Baxter operators on compact simple Lie groups and algebras
A Rota-Baxter operator on a Lie group $ G $ is a smooth map $ B : G \to G $ such that $ B(g)B(h) = B(gB(g)hB(g)^{-1}) $ for all $ g, h \in G $. This concept was introduced in 2021 by Guo, Lang and Sheng as a Lie group analogue of Rota-Baxter operators of weight 1 on Lie algebras. We show that the only Rota-Baxter operators on compact simple Lie groups are the trivial map and the inverse map. A similar description for Rota-Baxter operators of weight 1 on compact simple Lie algebras is provided.

In this paper, we prove the existence of classical solutions for the anisotropic surface diffusion with elasticity in the plane using a minimizing movements scheme, provided that the initial set is sufficiently regular. This scheme is inspired by the one introduced by Cahn-Taylor [15] to modeling the surface diffusion. Moreover, we prove that this scheme converges to the global solution of the equation.

We show that a very clear signal of the presence of a strong magnetic field during the early stage of a high-energy heavy-ion collision is provided by the decay of the Z^0 into dimuon pairs. We find that the process is highly anisotropic, producing pairs mainly out of plane, as signaled by a negative value of v_2, and leads to a harder antimuon transverse momentum spectrum, compared with that of the muon transverse momentum spectrum. We also show that the process does not produce a significant …

The Future of Solar modelling: requirements for a new generation of solar models
Helioseismology and solar modelling have enjoyed a golden era thanks to decades-long surveys from ground-based networks such as for example GONG, BiSON, IRIS and the SOHO and SDO space missions which have provided high-quality helioseismic observations that supplemented photometric, gravitational, size and shape, limb-darkening and spectroscopic constraints as well as measurements of neutrino fluxes. However, the success of solar models is also deeply rooted in progress in fundamental physics (…

First complete characterization of an X-Ray tube through combined measurements and Geant4 simulations
X-ray tubes are sources of X-rays used in various fields, ranging from radiographic imaging in medical physics to the characterization of detectors in particle physics. This article presents a method for the complete characterization of the Mini-X2 X-Ray tube from AMETEK, an X-ray source later used to characterize gas detectors in laboratory. Using data provided by the manual, we derive key operational parameters of the tube, such as the photon emission rate and the relationship between emissiv…

Implementing LoRa MIMO System for Internet of Things
Bandwidth constraints limit LoRa implementations. Contemporary IoT applications require higher throughput than that provided by LoRa. This work introduces a LoRa Multiple Input Multiple Output (MIMO) system and a spatial multiplexing algorithm to address LoRa's bandwidth limitation. The transceivers in the proposed approach modulate the signals on distinct frequencies of the same LoRa band. A Frequency Division Multiplexing (FDM) method is used at the transmitters to provide a wider MIMO channe…

Refining Labeling Functions with Limited Labeled Data
Programmatic weak supervision (PWS) significantly reduces human effort for labeling data by combining the outputs of user-provided labeling functions (LFs) on unlabeled datapoints. However, the quality of the generated labels depends directly on the accuracy of the LFs. In this work, we study the problem of fixing LFs based on a small set of labeled examples. Towards this goal, we develop novel techniques for repairing a set of LFs by minimally changing their results on the labeled examples suc…

The ALMA Survey of Gas Evolution of PROtoplanetary Disks (AGE-PRO): XI. Beam-corrected gas disk sizes from fitting 12CO moment zero maps
The inward drift of mm-cm sized pebbles in protoplanetary disks has become an important part of our current theories of planet formation and, more recently, planet composition as well. The gas-to-dust size ratio of protoplanetary disks can provide an important constraint on how pebbles have drifted inward provided that observational effects, especially resolution, can be accounted for. Here we present a method for fitting beam-convolved models to integrated intensity maps of line emission using…

Deterministic Switching of the Néel Vector by Asymmetric Spin Torque
Néel vector, the order parameter of collinear antiferromagnets, serves as a state variable in associated antiferromagnetic (AFM) spintronic devices to encode information. A deterministic switching of Néel vector is crucial for the write-in operation, which, however, remains a challenging problem in AFM spintronics. Here we demonstrate, based on analytical derivation and macro-spin simulations, that Néel vector switching can be generally achieved via a current-induced spin torque, provided th…

Variational inequalities associated with the semigroups generated by fractional Kolmogorov operators
In this paper we consider fractional Kolmogorov operators defined, in $\mathbb{R}^d$, by \[Λ_κ=(-Δ)^{α/2}+\fracκ{|x|^α} x\cdot \nabla,\] with $α\in (1,2)$, $α<(d+2)/2$ and $κ\in \mathbb{R}$. The operator $Λ_α$ generates a holomorphic semigroup $\{T_t^α\}_{t>0}$ in $L^2(\mathbb{R}^d)$ provided that $κ<κ_c$ where $κ_c$ is a critical coupling constant. We establish $L^p$-boundedness properties for the variation operators $V_ρ\left(\{t^\ell\partial_t^\ell T_t^α\}_{t>0…

Impact of angle-dependent recombination on neutrino energy reconstruction in LArTPCs
The technology of Liquid Argon Time-Projection Chambers (LArTPC) plays a very important role in modern neutrino physics. It allows precise tracking and calorimetry in detectors with very large volume and mass. One important component of LArTPC calorimetric energy reconstruction is the electron-ion recombination effect. Existing experiments have provided constraints to its empirical description, including an explicit dependence on the particle's angle with respect to the TPC's electric field. …

Fluid Antenna System-Assisted Self-Interference Cancellation for In-Band Full Duplex Communications
In-band full-duplex (IBFD) systems are expected to double the spectral efficiency compared to half-duplex systems, provided that loopback self-interference (SI) can be effectively suppressed. The inherent interference mitigation capabilities of the emerging fluid antenna system (FAS) technology make it a promising candidate for addressing the SI challenge in IBFD systems. This paper thus proposes a FAS-assisted self-interference cancellation (SIC) framework, which leverages a receiver-side FAS …

Smallest Suffixient Sets as a Repetitiveness Measure
Suffixient sets are a novel combinatorial object that capture the essential information of repetitive strings in a way that, provided with a random-access mechanism, supports various forms of pattern matching. In this paper we study the size $χ$ of the smallest suffixient set as a repetitiveness measure: we place it between known measures and study its sensitivity to various string operations.

Partial independent transversals in multipartite graphs
Given integers $r>d\ge 0$ and an $r$-partite graph, an independent $(r-d)$-transversal or $(r-d)$-IT is an independent set of size $r-d$ that intersects each part in at most one vertex. We show that every $r$-partite graph with maximum degree $Δ$ and parts of size $n$ contains an $(r-d)$-IT if $n> 2Δ(1-\frac{1}{q})$, provided $q= \lfloor \frac{r}{d+1}\rfloor\ge \frac{4r}{4d+5}$. This is tight when $q$ is even and extends a classical result of Haxell in the $d=0$ case. When $q= \lfloor \frac{r…

We analyse the exact solutions to some quantum-mechanical models derived recently by means of a generalization of the Frobenius method.

Special attention is given to scenarios involving state constraints. To illustrate the results, examples and applications are provided, with …

The torsion order in knot Floer homology is multiplicative for L-space knots under cabling
The knot Floer order $\operatorname{Ord}(K)$ is a knot invariant derived from the knot Floer homology. It bounds many invariants that are difficult to calculate. For all L-space cables of L-space knots, we prove that $\operatorname{Ord}(K) + 1$ is multiplicative in $p$ when $g(K) > 1$. The same holds for $g(K) = 1$, provided $q > 2p$. We further compute the knot Floer torsion order in the range $p < q < 2p$, thereby determining $\operatorname{Ord}(K_{p,q})$ from $\operatorname{Ord}(K)$ for all …

We report anomalous shot noise in nanojunctions of beta-tantalum, a ``bad" metal whose electronic properties are inconsistent with the Fermi liquid theory. Fano factors cluster around even multiples of the values expected for Fermi liquids, suggesting that beta-Ta may host a correlated charge liquid of Cooper pair-like electron groups. Further evidence for correlations is provided by the effects of magnetic impurities, as well as reduced density of states near the Fermi level indicated by point…

In this setting, optimal CEs require history-dependent policies; this poses new representational and algorithmic challenges as the number of possible histories grows exponentially with the number of time steps. We focus on computing $(ε, δ)$-optimal CEs -- solutions that achieve a value within $ε$ of an optimal CE, while al…
