Resolution and Betti numbers of Vertex cover ideals
The vertex cover ideal $J(G)$ of a finite graph $G$ is studied. We characterize when a Cohen--Macaulay vertex cover ideal $J(G)$ has a Scarf minimal free resolution. Furthermore, by using both combinatorial and topological techniques, the graded Betti number $β_{i,i+j}(J(G))$, where $i$ and $j$ are the projective dimension and the regularity of $J(G)$, is computed, when $G$ is either a path or a cycle.

Orbits and invariants for coisotropy representations
For a subgroup $H$ of a reductive group $G$, let $\mathfrak m\subset \mathfrak g^*$ be the cotangent space of $eH\in G/H$. The linear action $(H:\mathfrak m)$ is the coisotropy representation. It is known that the complexity and rank of $G/H$ (denoted $c$ and $r$, respectively) are encoded in properties of $(H:\mathfrak m)$. We complement existing results on $c$, $r$, and $(H:\mathfrak m)$, especially for quasiaffine varieties $G/H$. If the algebra of invariants $k[\mathfrak m]^H$ is finitely g…

When I had to replace my (dead) Athlon 64 X2 with a Ryzen 5, I wasn't exactly satisfied. Sure, it was much more performant. However, Athlon used to need no cooling when (almost) idle. This meant that I could e.g. play movies using VDPAU (passively cooled GPU) with practically no noise whatsoever.
Ryzen had a pretty noisy fan even when idle — even worse, it suffered from some kind of resonance when set to "silent" profile. So far a long time I've settled on having some level of fan noise.
A few days ago, I've decided to try something new and set my own fan curve. Now here's a fun fact: I've managed to set it to disable the fan below 50°C — and it just worked. I mean, it doesn't seem to stop it completely but run on low torque that keeps it silent — and that is entirely sufficient to keep it below 50°C when not doing any heavy lifting.
In fact, unless I enable boost, it manages to be quite silent under load as well.

Exploring the Influence of Graph Operations on Zero Forcing Sets
Zero forcing in graphs is a coloring process where a colored vertex can force its unique uncolored neighbor to be colored. A zero forcing set is a set of initially colored vertices capable of eventually coloring all vertices of the graph. In this paper, we focus on the numbers $z(G; i)$, which is the number of zero forcing sets of size $i$ of the graph $G$. These numbers were initially studied by Boyer et al. where they conjectured that for any graph $G$ on $n$ vertices, $z(G; i) \leq z(P_n; i)…

The Unique stationary boundary property
Let $G$ be a locally compact group and $μ$ an admissible probability measure on $G$. Let $(B,ν)$ be the universal topological Poisson $μ$-boundary of $(G,μ)$ and $Π_s(G)$ the universal minimal strongly proximal $G$-flow. In this note we present an alternative proof to a recent result of Hartman and Kalantar. We show that the following conditions are equivalent: (i) the measure $ν$ is the unique $μ$-stationary measure on $B$, (ii) $(B,G) \cong (Π_s(G),G)$.

These tests exhibit near optimality properties not only in classical i.i.d. observation models but also in general non-i.i.d…

Some stability results of positive mass theorem for uniformly asymptotically flat $3$-manifolds
In this paper, we show that for a sequence of orientable complete uniformly asymptotically flat $3$-manifolds $(M_i , g_i)$ with nonnegative scalar curvature and ADM mass $m(g_i)$ tending to zero, by subtracting some open subsets $Z_i$, whose boundary area satisfies $\mathrm{Area}(\partial Z_i) \leq Cm(g_i)^{1/2 - \varepsilon}$, for any base point $p_i \in M_i\setminus Z_i$, $(M_i\setminus Z_i,g_i,p_i)$ converges to the Euclidean space $(\mathbb{R}^3,g_E,0)$ in the $C^0$ modulo negligible volum…

Fast algorithms for Vizing's theorem on bounded degree graphs
Vizing's theorem states that every graph $G$ of maximum degree $Δ$ can be properly edge-colored using $Δ+ 1$ colors. The fastest currently known $(Δ+1)$-edge-coloring algorithm for general graphs is due to Sinnamon and runs in time $O(m\sqrt{n})$, where $n :=|V(G)|$ and $m :=|E(G)|$. We investigate the case when $Δ$ is constant, i.e., $Δ= O(1)$. In this regime, the runtime of Sinnamon's algorithm is $O(n^{3/2})$, which can be improved to $O(n \log n)$, as shown by Gabow…

Generating gaussian pseudorandom noise with binary sequences
Gaussian random number generators attract a widespread interest due to their applications in several fields. Important requirements include easy implementation, tail accuracy, and, finally, a flat spectrum. In this work, we study the applicability of uniform pseudorandom binary generators in combination with the Central Limit Theorem to propose an easy to implement, efficient and flexible algorithm that leverages the properties of the pseudorandom binary generator used as an input, specially wi…

Efficient Normalization of Linear Temporal Logic
In the mid 80s, Lichtenstein, Pnueli, and Zuck proved a classical theorem stating that every formula of Past LTL (the extension of LTL with past operators) is equivalent to a formula of the form $\bigwedge_{i=1}^n \mathbf{G}\mathbf{F}\, φ_i \vee \mathbf{F}\mathbf{G}\, ψ_i $, where $φ_i$ and $ψ_i$ contain only past operators. Some years later, Chang, Manna, and Pnueli built on this result to derive a similar normal form for LTL. Both normalization procedures have a non-elementary worst-case …

Viable Wormhole Solutions in Modified Gauss-Bonnet Gravity
In this paper, we use the embedding class-I technique to examine the effect of charge on traversable wormhole geometry in the context of $f(\mathcal{G})$ theory, where $\mathcal{G}$ is the Gauss-Bonnet term. For this purpose, we consider static spherical spacetime with anisotropic matter configuration to investigate the wormhole geometry. The Karmarkar condition is used to develop a shape function for the static wormhole structure. Using this developed shape function, we construct a wormhole ge…

Quantum critical fluctuations generate intensely magnetic field-resilient superconductivity in UTe2
Quantum critical phase boundaries (QCPBs) -- where a continuous phase transition occurs at zero temperature -- have been found to nucleate novel electronic states in a number of strongly correlated materials. Emergent electronic phases, such as unconventional superconductivity, frequently occur in close proximity to a QCPB. However, the antagonism between magnetic field and superconductivity generally suppresses such superconductive phases to modest magnetic field ranges, except in notable case…

Characterization of contaminants in the Lyman-alpha forest auto-correlation with DESI
Baryon Acoustic Oscillations can be measured with sub-percent precision above redshift two with the Lyman-alpha forest auto-correlation and its cross-correlation with quasar positions. This is one of the key goals of the Dark Energy Spectroscopic Instrument (DESI) which started its main survey in May 2021. We present in this paper a study of the contaminants to the lyman-alpha forest which are mainly caused by correlated signals introduced by the spectroscopic data processing pipeline as well a…

Abstract: In this study, we investigate interstellar absorption lines along the line of sight toward the galactic low-mass X-ray binary Cygnus X-2. We combine absorption line data obtained from high-resolution X-ray spectra collected with Chandra and XMM-Newton satellites, along with Far-UV absorption lines observed by the Hubble Space Telescope's (HST) Cosmic Origins Spectrograph (COS) Instrument. Our primary objective is to understand the abundance and depletion of oxygen, iron, sulfur, and carbon. To achieve this, we have developed an analysis pipeline that simultaneously fits both the UV and X-ray datasets. This novel approach takes into account the line spread function (LSF) of HST/COS, enhancing the precision of our results. We examine the absorption lines of FeII, SII, CII, and CI present in the FUV spectrum of Cygnus X-2, revealing the presence of at least two distinct absorbers characterized by different velocities. Additionally, we employ Cloudy simulations to compare our findings concerning the ionic ratios for the studied elements. We find that gaseous iron and sulfur exist in their singly ionized forms, Fe II and S II, respectively, while the abundances of CII and CI do not agree with the Cloudy simulations of the neutral ISM. Finally, we explore discrepancies in the X-ray atomic data of iron and discuss their impact on the overall abundance and depletion of iron.

The Unique stationary boundary property
Let $G$ be a locally compact group and $μ$ an admissible probability measure on $G$. Let $(B,ν)$ be the universal topological Poisson $μ$-boundary of $(G,μ)$ and $Π_s(G)$ the universal minimal strongly proximal $G$-flow. In this note we present an alternative proof to a recent result of Hartman and Kalantar. We show that the following conditions are equivalent: (i) the measure $ν$ is the unique $μ$-stationary measure on $B$, (ii) $(B,G) \cong (Π_s(G),G)$.

Giant effective $g$-factor due to spin bifurcations in polariton condensates
We predict giant susceptibility of spin-bifurcating polariton condensates to externally applied permanent magnetic field. In the presence of spin-anisotropic polariton-polariton interactions, the condensate spontaneously takes an elliptically polarised state, {whose perturbation dynamics can be interpreted in terms of the presence of strong effective magnetic field} significantly surpassing the external one. Surprisingly, this behaviour of the addressed strongly out-of-equilibrium system in the…

Opinion inertia and coarsening in the Persistent Voter model
We consider the Persistent Voter model (PVM), a variant of the Voter model (VM) that includes transient, dynamically-induced zealots. Due to peer reinforcement, the internal confidence $η_i$ of a normal voter increases by steps of size $Δη$ and once it gets above a given threshold, it becomes a zealot. Then, its opinion remains frozen until enough interactions with the opposite opinion occur and its confidence is reset. No longer a zealot, the regular voter may change opinion once again. Thi…

Constraints on conformal ultralight dark matter couplings from the European Pulsar Timing Array
Millisecond pulsars are extremely precise celestial clocks: as they rotate, the beamed radio waves emitted along the axis of their magnetic field can be detected with radio telescopes, which allows for tracking subtle changes in the pulsars' rotation periods. A possible effect on the period of a pulsar is given by a potential coupling to dark matter, in cases where it is modeled with an "ultralight" scalar field. In this paper, we consider a universal conformal coupling of the dark matter scala…
