description: During primordial star formation, the main cooling channel is provided by H$_{2}$ and super-molecules, such as H$_{2}$ or H$_{2}$, at sufficiently high densities. When the latter form at $n_{\rm H}$ $\geq$ $10^{14}$~cm$^{-3}$, collision-induced emission (CIE) provides efficient gas cooling. We investigate how CIE cooling affects the formation of metal-free binaries comparing simulations with and without this process. Irrespective of the cooling mechanism, we find a typical protostellar mass range between 0.01 to 100 M$_{\odot}$. However, models with only H$_{2}$ line cooling produce a greater number of low-mass protostars which exhibit stronger variations in their radial velocities than the high-mass protostars. Similarly, in models with both H$_{2}$ cooling and CIE cooling, significant variations in the radial velocities are found for protostars in the intermediate mass range. The initial number of fragments $N_{\rm max}$ decreases with increasing strength of turbulence. Cooling via super-molecules lets the most massive protobinaries (MMPBs) efficiently accrete mass. The maximum mass accretion rate $\dot M_{\rm max}$ for the MMPBs is more than an order of magnitude higher in the presence of CIE cooling than for pure H$_{2}$ line cooling. As a result, compact binaries with a semi-major axis as small as 3.57 au may form through the H$_{2}$ $-$ H$_{2}$ cooling channel. Our results indicate that in addition to the MMPBs most population III (Pop. III) binaries should be in eccentric i.e. non-circular orbits. This provides an important connection to the eccentric binaries reported in previous studies, which were found to exhibit rich temporal accretion signals during their evolution.

description: The dynamical excitation of asteroids due to mean motion resonant interactions with planets is enhanced when their parent star leaves the main sequence. However, numerical investigation of resonant outcomes within post-main-sequence simulations is computationally expensive, limiting the extent to which detailed resonant analyses have been performed. Here, we combine the use of a high-performance computer cluster and the general semianalytical libration width formulation of Gallardo et al. (2021) in order to quantify resonant stability, strength and variation instigated by stellar evolution for a single-planet system containing asteroids on both crossing and non-crossing orbits. We find that resonant instability can be accurately bound with only main-sequence values by computing a maximum libration width as a function of asteroid longitude of pericentre. We also quantify the relative efficiency of mean motion resonances of different orders to stabilize versus destabilize asteroid orbits during both the giant branch and white dwarf phases. The 4:1, 3:1 and 2:1 resonances represent efficient polluters of white dwarfs, and even when in the orbit-crossing regime, both the 4:3 and 3:2 resonances can retain small reservoirs of asteroids in stable orbits throughout giant branch and white dwarf evolution. This investigation represents a preliminary step in characterising how simplified extrasolar Kirkwood gap structures evolve beyond the main-sequence.

description: M-dwarf stars account for more than 70% of the stars in our galaxy and have an important role in several astrophysical contexts, for instance, as prime targets in the search for life outside our Solar System. In this work we aim to identify and characterise M dwarfs in the b294 tile from Vista Variables in the Vía Láctea (VVV) survey, a deep near-infrared survey towards Galactic southern plane. We used parallax measurements and proper motions from Gaia Early Data Release 3, in addition to different colour cuts based on VISTA filters, to select a list of 7896 M dwarfs within tile b294. We performed a SED fitting to obtain the effective temperature for all objects using broad-band photometry available at Virtual Observatory archives. The objects in our sample have temperatures varying from 2800 to 3900 K. In the near future, we will search for transit-like events in the VVV light curves with around 300 observed epochs.

description: A coherently oscillating real scalar field with potential shallower than quadratic one fragments into spherical objects called I-balls. We study the I-ball formation for logarithmic potential which appears in many cosmological models. We perform lattice simulations and find that the I-balls are formed when the potential becomes dominated by the quadratic term. Furthermore, we estimate the I-ball profile assuming that the adiabatic invariant is conserved during formation and obtain the result that agrees to the numerical simulations.

description: We introduce an invariant, called mean rank, for any module M of the integral group ring of a discrete amenable group $Γ$, as an analogue of the rank of an abelian group. It is shown that the mean dimension of the induced $Γ$-action on the Pontryagin dual of M, the mean rank of M, and the von Neumann-Lück rank of M all coincide. As applications, we establish an addition formula for mean dimension of algebraic actions, prove the analogue of the Pontryagin-Schnirelmnn theorem for algebraic actions, and show that for elementary amenable groups with an upper bound on the orders of finite subgroups, algebraic actions with zero mean dimension are inverse limits of finite entropy actions.

A Line Source in Minkowski for the de Sitter Spacetime Scalar Green's Function: Massive Case

description: For certain classes of space(time)s embeddable in a higher dimensional flat space(time), it appears possible to compute the minimally coupled massless scalar Green's function in the former by convolving its cousin in the latter with an appropriate scalar charge density. The physical interpretation is that beings residing in the higher dimensional flat space(time) may set up sources to fool the observer confined on the lower dimensional curved submanifold that she is detecting the field generated by a space(time) point source in her own world. In this paper we extend the general formula to include a non-zero mass. We then employ it to derive the Green's function of the massive wave operator in (d >= 2)-dimensional de Sitter spacetime and that of the Helmholtz differential operator -- the Laplacian plus a "mass term" -- on the (d >= 2)-sphere. For both cases, the trajectories of the scalar sources are the same as that of the massless case, while the required scalar charge densities are determined by solving an eigenvalue equation. To source these massive Green's functions, we show that the (d+1)-dimensional Minkowski/Euclidean experimentalists may choose to use either massive or massless scalar line charges. In de Sitter spacetime, the embedding method employed here leads directly to a manifest separation between the null cone versus tail terms of the Green's functions.

description: Magnetic Particle Imaging (MPI) is a fast imaging technique for the visualization of the distribution of superparamagnetic iron-oxide nanoparticles (SPIONs) in 3D. For spatial encoding, a field free area is moved rapidly through the field of view (FOV) generating a localized signal. Fast moving samples, e.g., a bolus of SPIONs traveling through the large veins in the human body carried by blood flow with velocities in the order of ~45 cm/s and higher, cause temporal blurring in MPI measurements using common sequences and reconstruction techniques. This hampers the evaluation of dynamics of rapidly moving samples. In this abstract, initial results of rapidly moving samples in form of SPION boluses visualized within an MPI scanner are shown.

description: We prove a rank-finiteness conjecture for modular categories: up to equivalence, there are only finitely many modular categories of any fixed rank. Our technical advance is a generalization of the Cauchy theorem in group theory to the context of spherical fusion categories. For a modular category $\mathcal{C}$ with $N=ord(T)$, the order of the modular $T$-matrix, the Cauchy theorem says that the set of primes dividing the global quantum dimension $D^2$ in the Dedekind domain $\mathbb{Z}[e^{\frac{2πi}{N}}]$ is identical to that of $N$.

description: The goal of this paper is to understand Latino voting behavior during the 2016 and 2020 presidential elections using precinct-level analysis. The 2016 and 2020 presidential elections were cases of elections where Latinos were demonstrated to have voted for Republican candidates in surprising numbers. Analysis of data from precincts with high proportions of Latino citizen voting age population was utilized to provide a comprehensive description of the Latino electorate and address the ecological inference problem that emerges when attempting to infer voting behavior of electorate subgroups like Latinos using aggregate data. Using precinct-level Latino demographic data created for this analysis, Latinos were found to have voted more Republican in 2020 than in 2016. Additionally, in 2020, Latinos were found to lean more Republican than non-Latinos in precincts with high proportions of Latino citizen voting age population.

Year: 2025

This study fabricates and characterizes a concentric tri-axis fluxgate magnetometer. The vector magnetometer consists of a tubular soft flux chopper with a toroidal coil and three concentric pick-up coils. The Z-axis pick-up coil is placed in the cavity of the flux chopper to reduce the size of the sensor. With the X and Y-axis pick-up coils enclosing the flux chopper and the Z-axis coil at the center, the three sensing axes are concentric and the overall size of the vector magnetometer is no more than 10 mm×15 mm×15 mm. The concentric coils ensure a single field point for the X, Y, and Z- sensing axes while achieving high orthogonality. The achieved non-orthogonality errors are less than ±1°. The three-axis fluxgate control circuit based on second harmonic detection and magnetic field feedback is also developed to improve the non-linearity. The built circuit can generate an AC excitation signal and efficiently demodulate the three-axis outputs of the concentric fluxgate sensor to produce three separate DC voltage signals in proportion to the external quasi-static magnetic field. With feedback, the average non-linearity is less than 0.1% in the ±60 μT range. The proposed design concept is valuable for developing the compact and sensitive vector magnetometer for applications regarding precise geomagnetic measurement.

description: We study the space of complete Riemannian metrics of nonnegative curvature on the plane equipped with the C^k topology. If k is infinite, we show that the space is homeomorphic to the separable Hilbert space. For any k we prove that the space cannot be made disconnected by removing a finite dimensional subset. A similar result holds for the associated moduli space. The proof combines properties of subharmonic functions with results of infinite dimensional topology and dimension theory. A key step is a characterization of the conformal factors that make the standard Euclidean metric on the plane into a complete metric of nonnegative sectional curvature.

description: Close encounters between two initially unbound objects can result in a binary system if enough energy is released as gravitational waves (GWs). We address the scenario in which such encounters occur in merging elliptical galaxies. There is evidence that elliptical galaxies can harbor intermediate-mass black holes. Therefore, these systems are potentially the breeding grounds of sources of gravitational waves corresponding to inspiraling compact objects onto a massive black hole due to the dynamics, the large densities, and the number of compact remnants they contain. We show that this process is efficient for intermediate-mass black holes (IMBHs) with masses ranging from M $\in (10^3,10^5)$ M$_{\odot}$ and results in the formation of intermediate mass-ratio inspirals (IMRIs). We consider a set of IMBHs and smaller black holes with masses $m_2 \in (10,10^3)$ M$_{\odot}$ to estimate the IMRI formation rate. We find rates ranging between 10$^{-8}$ yr$^{-1}$, and 10$^{-5}$ yr$^{-1}$, and the IMRI formation rate per comoving volume in merging galaxies as a function of the redshift. The peak frequencies of the gravitational radiation emitted when these IMRIs are formed are within the detection band of space-borne detectors such as LISA and TianQin; taking into account the observable volume of these detectors, the total amount of IMRI detections per year is significant.

description: We have characterised detached eclipsing binaries from the Kepler field with low mass components by adopting a purely-photometric method to derive stellar parameters. For that, we used an extensive multi-colour dataset to estimate effective temperatures and photometric masses of individual components, based on broad-band photometric data from 2MASS and Pan-STARRS, and applying machine learning methods, such as the clustering technique. We also estimated their radii from additional modelling of the available Kepler light curves using the JKTEBOP code, associated with an asexual genetic algorithm. Our measurements show a persistent radius inflation trend, with measured stellar radii larger than model values by over 20% (despite individual uncertainties) in the low-mass regime. Spectroscopic masses are still needed to confirm the observed radius anomaly and its causes in late-type components of short-period binary systems.

description: Scholars in Black Studies and Religious Studies have developed a wealth of knowledge regarding how Black women have historically and contemporarily navigated Afro-Protestant church environments. They discuss how Black women use these environments to cultivate meanings of womanhood through church work, as well as how the sexual politics of these environments impacted notions of purity, modesty, and sanctification. This study builds on this by drawing on three social media-based content creators who are Black Christian women and target their content at a Black female audience. JC, NR, and KG are all aged 18-24, are currently students, and keep Christianity at the center of their content. Their Black female identities are salient in their content, as is derived from their use of phrases and descriptors specifically related to the Black experiences. Between the three of them, I watched 123 total videos from their publicly available profiles on YouTube and Tik Tok. I extracted themes of sexual conservatism, purity, modesty, abstinence, self-love, and validation to make an argument that they rely on these things to cultivate meanings of Black womanhood in a contemporary landscape. These women overwhelmingly agree that sexual purity and modesty are what sets them apart from general society, also holding that valuing such things is the outcome of first pursuing close communion with God. They also make stern declarations that self-love is a biblically backed command, arguing that in order to love others properly it is required to love themselves. The unique experience of Black womanhood informs their attitudes toward validation. As Black women, they describe pressure to always look put together or present to the world in a certain way, which led them to seek validation from others rather than God and themselves. All these experiences are what they describe as characterizing Black Christian womanhood, and they use their social media platforms to communicate this to their audiences.
Message Authentication Code over a Wiretap Channel

description: Message Authentication Code (MAC) is a keyed function $f_K$ such that when Alice, who shares the secret $K$ with Bob, sends $f_K(M)$ to the latter, Bob will be assured of the integrity and authenticity of $M$. Traditionally, it is assumed that the channel is noiseless. However, Maurer showed that in this case an attacker can succeed with probability $2^{-\frac{H(K)}{\ell+1}}$ after authenticating $\ell$ messages. In this paper, we consider the setting where the channel is noisy. Specifically, Alice and Bob are connected by a discrete memoryless channel (DMC) $W_1$ and a noiseless but insecure channel. In addition, an attacker Oscar is connected with Alice through DMC $W_2$ and with Bob through a noiseless channel. In this setting, we study the framework that sends $M$ over the noiseless channel and the traditional MAC $f_K(M)$ over channel $(W_1, W_2)$. We regard the noisy channel as an expensive resource and define the authentication rate $ρ_{auth}$ as the ratio of message length to the number $n$ of channel $W_1$ uses. The security of this framework depends on the channel coding scheme for $f_K(M)$. A natural coding scheme is to use the secrecy capacity achieving code of Csiszár and Körner. Intuitively, this is also the optimal strategy. However, we propose a coding scheme that achieves a higher $ρ_{auth}.$ Our crucial point for this is that in the secrecy capacity setting, Bob needs to recover $f_K(M)$ while in our coding scheme this is not necessary. How to detect the attack without recovering $f_K(M)$ is the main contribution of this work. We achieve this through random coding techniques.

description: Envelope tests are a popular tool in spatial statistics, where they are used in goodness-of-fit testing. These tests graphically compare an empirical function $T(r)$ with its simulated counterparts from the null model. However, the type I error probability $α$ is conventionally controlled for a fixed distance $r$ only, whereas the functions are inspected on an interval of distances $I$. In this study, we propose two approaches related to Barnard's Monte Carlo test for building global envelope tests on $I$:(1) ordering the empirical and simulated functions based on their $r$-wise ranks among each other, and (2) the construction of envelopes for a deviation test. These new tests allow the a priori selection of the global $α$ and they yield $p$-values. We illustrate these tests using simulated and real point pattern data.

description: Weak values and measurements have been proposed as means to achieve dramatic enhancements in metrology based on the greatly increased range of possible measurement outcomes. Unfortunately, the very large values of measurement outcomes occur with highly suppressed probabilities. This raises three vital questions in weak-measurement-based metrology, namely, (Q1) Does post-selection enhance the measurement precision? (Q2) Does weak measurement offer better precision than strong measurement? (Q3) Is it possible to beat the standard quantum limit or to achieve the Heisenberg limit with weak measurement using only classical resources? We analyse these questions for two prototypical, and generic, measurement protocols and show that while the answers to the first two questions are negative for both protocols, the answer to the last is affirmative for measurements with phase-space interactions, and negative for configuration space interactions. Our results, particularly the ability of weak measurements to perform at par with strong measurements in some cases, are instructive for the design of weak-measurement-based protocols for quantum metrology.

description: For the upcoming PLAnetary Transits and Oscillation of stars (PLATO) satellite mission, a large number of target stars are required to yield a statistically significant number of planet transits. Locating the centres of the long duration observational phase (LOP) fields closer to the Galactic plane will increase the target star numbers but also the astrophysical false positives (FPs) from blended eclipsing binary systems. We utilise the Binary Stellar Evolution and Population Synthesis (BiSEPS) code, to create a complete synthetic stellar and planetary population for the proposed southern LOP field (LOPS0), as well as for a representative portion of the northern LOP field (LOPNsub). For LOPS0 we find an overall low FP rate for planets smaller than Neptunes. The FP rate generally shows little variation with Galactic longitude (l), and a modest increase with decreasing Galactic latitude (|b|). The location of the LOPS field centre within the current allowed region is not strongly constrained by FPs. Analysis of LOPNsub suggests a markedly increased number of FPs across the full range of planet radii at low |b| resulting in approximately twice the percent FP rate in the LOPNsub compared to the corresponding southern field segment in the planet radius range -0.2 < log(R/Rsun) <= 0.4.

description: Borel summable divergent series usually appear when studying solutions of analytic ODE near a multiple singular point. Their sum, uniquely defined in certain sectors of the complex plane, is obtained via the Borel--Laplace transformation. This article shows how to generalize the Borel--Laplace transformation in order to investigate bounded solutions of parameter dependent non-linear differential systems with two simple (regular) singular points unfolding a double (irregular) singularity. We construct parametric solutions on domains attached to both singularities, that converge locally uniformly to the sectoral Borel sums. Our approach provides a unified treatment for all values of the complex parameter.

description: We develop a model-based methodology for integrating gene-set information with an experimentally-derived gene list. The methodology uses a previously reported sampling model, but takes advantage of natural constraints in the high-dimensional discrete parameter space in order to work from a more structured prior distribution than is currently available. We show how the natural constraints are expressed in terms of linear inequality constraints within a set of binary latent variables. Further, the currently available prior gives low probability to these constraints in complex systems, such as Gene Ontology (GO), thus reducing the efficiency of statistical inference. We develop two computational advances to enable posterior inference within the constrained parameter space: one using integer linear programming for optimization and one using a penalized Markov chain sampler. Numerical experiments demonstrate the utility of the new methodology for a multivariate integration of genomic data with GO or related information systems. Compared to available methods, the proposed multi-functional analyzer covers more reported genes without mis-covering nonreported genes, as demonstrated on genome-wide data from association studies of type 2 diabetes and from RNA interference studies of influenza.

Banach space projections and Petrov-Galerkin estimates

description: We sharpen the classic a priori error estimate of Babuska for Petrov-Galerkin methods on a Banach space. In particular, we do so by (i) introducing a new constant, called the Banach-Mazur constant, to describe the geometry of a normed vector space; (ii) showing that, for a nontrivial projection $P$, it is possible to use the Banach-Mazur constant to improve upon the naive estimate $ \| I - P \| \leq 1 + \| P \| $; and (iii) applying that improved estimate to the Petrov-Galerkin projection operator. This generalizes and extends a 2003 result of Xu and Zikatanov for the special case of Hilbert spaces.

Stein factors for negative binomial approximation in Wasserstein distance

Publisher: name: arXiv

Subjects: subject: Probability (math.PR)

description: The paper gives the bounds on the solutions to a Stein equation for the negative binomial distribution that are needed for approximation in terms of the Wasserstein metric. The proofs are probabilistic, and follow the approach introduced in Barbour and Xia (Bernoulli 12 (2006) 943-954). The bounds are used to quantify the accuracy of negative binomial approximation to parasite counts in hosts. Since the infectivity of a population can be expected to be proportional to its total parasite burden, the Wasserstein metric is the appropriate choice.

Ernesto Rossi e La Riforma Sociale (1926-1930). La carriera interrotta di un economista ‘politico’
Creators: name: Asso, Pier Francesco
name: Nerozzi, Sebastiano
Publisher: name: Moneta e Credito
Year: 2022

description: Con questo saggio si intende ricostruire la breve ma intensa fase di collaborazione di Ernesto Rossi con La Riforma Sociale, prestigiosa rivista di economia e scienze sociali fondata da Francesco Saverio Nitti nel 1894 e diretta da Luigi Einaudi dal 1908. Fra il 1926 e il 1930 Rossi è autore di sette lunghi saggi su tematiche di finanza pubblica, economia applicata e statistica economica che sono stati relativamente trascurati dalla storiografia. La rilettura di questi contributi consente di approfondire alcuni momenti centrali nella sua formazione di economista. In particolare: l’influenza di Einaudi e di De Viti de Marco; la predilezione per un approccio empirico all’analisi economica; la critica precoce nei confronti della politica economica finanziaria del fascismo.

KELT-9 and its ultra-hot Jupiter: stellar parameters, composition, and planetary pollution

description: KELT-9b is an ultra-hot Jupiter observed to be undergoing extreme mass loss. Its A0-type host star has a radiative envelope, which makes its surface layers prone to retaining recently accreted material. To search for potential signs of planetary material polluting the stellar surface, we carry out the most comprehensive chemical characterisation of KELT-9 to-date. New element detections include Na and Y, which had previously been detected in the ultra-hot Jupiter but not studied in the star; these detections complete the set of nine elements measured in both star and planet. In comparing KELT-9 with similar open cluster stars we find no strong anomalies. This finding is consistent with calculations of photospheric pollution accounting for stellar mixing and using observationally estimated KELT-9b mass loss rates. We also rule out recent, short-lived intensive mass transfer such as the stellar ingestion of an Earth-mass exomoon.

Ernesto Rossi e lo Stato imprenditore. I convegni degli Amici del Mondo per la nazionalizzazione dell’industria elettrica
Creators: name: Braga, Antonella
Publisher: name: Moneta e Credito
Year: 2022

description: Questo contributo si concentra sulla battaglia per la gestione pubblica dell’energia elettrica promossa dall’economista Ernesto Rossi con il sostegno del gruppo Amici del Mondo. Tra il 1955 e il 1964 furono organizzati da questa associazione, nata intorno all’omonima rivista diretta da Mario Pannunzio, dodici convegni. Due di essi furono dedicati alla nazionalizzazione del settore elettrico ed elettronucleare, secondo un lucido progetto di “pianificazione liberale”. Questo contributo esplora il contesto in cui si svolsero questi incontri, il ruolo di Rossi, le proposte emerse dal dibattito e i risultati ottenuti in termini di legislazione e sensibilizzazione dell’opinione pubblica.

description: We prove a rigidity result in the sphere which allows us to generalize a result about smooth convex hypersurfaces in the sphere by Do Carmo-Warner to convex $C^2$-hypersurfaces. We apply these results to prove $C^{1,β}$-convergence of inverse F-curvature flows in the sphere to an equator in \mathbb{S}^{n+1} for embedded, closed, strictly convex initial hypersurfaces. The result holds for large classes of curvature functions including the mean curvature and arbitrary powers of the Gauss curvature. We use this result to prove Alexandrov-Fenchel type inequalities in the sphere.

Ernesto Rossi e la “scienza triste”, tra Wicksteed e Robbins
Creators: name: Carparelli, Antonia
Publisher: name: Moneta e Credito
Year: 2022

description: Ernesto Rossi ha affermato in più occasioni che l’economista che ha maggiormente influenzato il suo pensiero è Philip Wicksteed, cui si riconosce il merito di aver completato la “rivoluzione marginalista”. Il presente contributo mette in evidenza il forte influsso di Lionel Robbins, le cui opere Rossi studiò estesamente e approfonditamente negli anni del carcere e del confino, e che fu tra l’altro il principale promotore dell’opera di Wicksteed. La linea di pensiero che accomuna Ernesto Rossi a Lionel Robbins parte da Pareto, passa per Wicksteed e approda al federalismo, inteso come quadro istituzionale necessario per la piena affermazione di un ordine economico e politico liberale. Rossi condivide con Robbins l’approccio teorico e il rigore metodologico, compresa l’idea della neutralità della scienza economica e della possibilità di far uso dei suoi strumenti nell’ambito di diversi sistemi normativi. Al tempo stesso, nell’applicazione pratica degli strumenti teorici Rossi appare molto vicino al socialismo democratico e liberale britannico, come rappresentato ad esempio da Barbara Wootton nella sua opera Lament for economics.
