Massive stars evolution with new C12+C12 nuclear reaction rate -- the core carbon-burning phase
Nuclear reactions drive the stellar evolution and contribute to the stellar and galactic chemicals abundances. New determinations of the nuclear reaction rates for key fusion reactions of stellar evolution are now available, paving the way to improved stellar model predictions. We explore the impact of new C12+C12 reaction rates for massive stars evolution, structure, and nucleosynthesis during core carbon-burning phase. We analyse the consequences for stars of different masses including rotati…

Hilbert evolution algebras, weighted digraphs, and nilpotency
Hilbert evolution algebras generalize evolution algebras through a framework of Hilbert spaces. In this work we focus on infinite-dimensional Hilbert evolution algebras and their representation through a suitably defined weighted digraph. By means of studying such a digraph we obtain new properties for these structures extending well-known results related to the nilpotency of finite dimensional evolution algebras. We show that differently from what happens for the finite dimensional evolution a…

Classical-Quantum correspondence in Lindblad evolution
We show that for the Lindblad evolution defined using (at most) quadratically growing classical Hamiltonians and (at most) linearly growing classical jump functions (quantized into jump operators assumed to satisfy certain ellipticity conditions and modeling interaction with a larger system), the evolution of a quantum observable remains close to the classical Fokker--Planck evolution in the Hilbert--Schmidt norm for times vastly exceeding the Ehrenfest time (the limit of such agreement with no…

Evolution of secondary electron spectrum during cosmic-ray discharge in the universe
We recently found that streaming cosmic rays (CRs) induce a resistive electric field that can accelerate secondary electrons produced by CR ionization. In this work, we study the evolution of the energy spectrum of secondary electrons by numerically solving the one-dimensional Boltzmann equation and Ohm's law. We show that the accelerated secondary electrons further ionize a gas, that is, the electron avalanche occurs, resulting in increased ionization and excitation of the gas. Although the re…

Sharpening the dark matter signature in gravitational waveforms I: Accretion and eccentricity evolution
Dark matter overdensities around black holes can alter the dynamical evolution of a companion object orbiting around it, and cause a dephasing of the gravitational waveform. Here, we present a refined calculation of the co-evolution of the binary and the dark matter distribution, taking into account the accretion of dark matter particles on the companion black hole, and generalizing previous quasi-circular calculations to the general case of eccentric orbits. These calculations are validated by…

The evolution of the permutahedron
In their seminal paper introducing the theory of random graphs, Erdős and Rényi considered the evolution of the structure of a random subgraph of $K_n$ as the density increases from $0$ to $1$, identifying two key points in this evolution -- the \emph{percolation threshold}, where the order of the largest component seemingly jumps from logarithmic to linear in size, and the \emph{connectivity threshold}, where the subgraph becomes connected. Similar phenomena have been observed in many other …

Abstract: We explore the quasiparticle dynamics in bilayer nickelate La$_3$Ni$_2$O$_7$ crystal using ultrafast optical pump-probe spectroscopy at high pressure up to 34.2 GPa. At ambient pressure, the temperature dependence of relaxation indicates appearance of phonon bottleneck effect due to the opening of density-wave-like gap at 151 K. By analyzing the data with RT model, we identified the energy scale of the gap to be 70 meV at ambient pressure. The relaxation bottleneck effect is suppressed gradually by the pressure and disappears around 26 GPa. At high pressure above 29.4 GPa, we discover a new density-wave like order with transition temperature of $\sim$130 K. Our results not only provide the first experimental evidence of the density-wave like gap evolution under high pressure, but also offering insight into the underline interplay between the density wave order and superconductivity in pressured La$_3$Ni$_2$O$_7$.

arXiv:2404.19267v1 Announce Type: new
Abstract: The Bradford's law of bibliographic scattering is a fundamental law in bibliometrics and can provide valuable guidance to academic libraries in literature search and procurement. However, the Bradford's curves can take various shapes at different time points and there is still a lack of causal explanation for it, so the prediction of its shape is still an open question. This paper attributes the deviation of Bradford curve from the theoretical J-shape to the integer constraints of the journal number and article number, and extends the Leimkuhler and Egghe's formula to cover the core region of very productive journals, where the theoretical journal number of which fall below one. The key parameters of the extended formula are identified and studied by using the Simon-Yule model. The reasons for the Groos Droop are explained and the critical point for the shape change are studied. Finally, the proposed formulae are validated with the empirical data found in the literature. It is found that the proposed method can be used to predict the evolution of Bradford's curves and thus guide the academic library for scientific literature procurement and utilization.

On the origin of mixed morphology supernova remnants: Linking their properties to the evolution of a red supergiant progenitor star
Mixed-morphology supernova remnants (MMSNRs) are characterized by a shell-like morphology in the radio and centrally-peaked thermal emission in the X-ray band. The nature of this peculiar class of supernova remnants (SNRs) remains a controversial issue. In this work, by pairing the predictions of stellar evolution theory with two-dimensional hydrodynamic simulations we show that the mixed morphology properties of a SNR can arise by the interaction of the SNR with the circumstellar medium shaped…

Cutting $γ$-Liouville quantum gravity by Schramm-Loewner evolution for $κ\not\in \{γ^2, 16/γ^2\}$
There are many deep and useful theorems relating Schramm-Loewner evolution (SLE$_κ$) and Liouville quantum gravity ($γ$-LQG) in the case when the parameters satisfy $κ\in \{γ^2, 16/γ^2\}$. Roughly speaking, these theorems say that the SLE$_κ$ curve cuts the $γ$-LQG surface into two or more independent $γ$-LQG surfaces. We extend these theorems to the case when $κ\not\in \{γ^2, 16/γ^2\}$. Roughly speaking we show that if we have an appropriate variant of SLE$_κ$ and an independent $�…

Abstract: Large Language Models (LLMs) have catalyzed significant advancements in Natural Language Processing (NLP), yet they encounter challenges such as hallucination and the need for domain-specific knowledge. To mitigate these, recent methodologies have integrated information retrieved from external resources with LLMs, substantially enhancing their performance across NLP tasks. This survey paper addresses the absence of a comprehensive overview on Retrieval-Augmented Language Models (RALMs), both Retrieval-Augmented Generation (RAG) and Retrieval-Augmented Understanding (RAU), providing an in-depth examination of their paradigm, evolution, taxonomy, and applications. The paper discusses the essential components of RALMs, including Retrievers, Language Models, and Augmentations, and how their interactions lead to diverse model structures and applications. RALMs demonstrate utility in a spectrum of tasks, from translation and dialogue systems to knowledge-intensive applications. The survey includes several evaluation methods of RALMs, emphasizing the importance of robustness, accuracy, and relevance in their assessment. It also acknowledges the limitations of RALMs, particularly in retrieval quality and computational efficiency, offering directions for future research. In conclusion, this survey aims to offer a structured insight into RALMs, their potential, and the avenues for their future development in NLP.

Abstract: Recent developments in low-field (LF) magnetic resonance imaging (MRI) systems present remarkable opportunities for affordable and widespread MRI access. A robust denoising method to overcome the intrinsic low signal-noise-ratio (SNR) barrier is critical to the success of LF MRI. However, current data-driven MRI denoising methods predominantly handle magnitude images and rely on customized models with constrained data diversity and quantity, which exhibit limited generalizability in clinical applications across diverse MRI systems, pulse sequences, and organs. In this study, we present ImT-MRD: a complex-valued imaging transformer trained on a vast number of clinical MRI scans aiming at universal MR denoising at LF systems. Compared with averaging multiple-repeated scans for higher image SNR, the model obtains better image quality from fewer repetitions, demonstrating its capability for accelerating scans under various clinical settings. Moreover, with its complex-valued image input, the model can denoise intermediate results before advanced post-processing and prepare high-quality data for further MRI research. By delivering universal and accurate denoising across clinical and research tasks, our model holds great promise to expedite the evolution of LF MRI for accessible and equal biomedical applications.

Neutrinos are evolved with an explicit Monte Carlo method and can interact with matter via emission, absorption, or scattering. Within the postprocessing framew…

Disentangling the co-evolution of galaxies and supermassive black holes with PRIMA
The most active phases of star formation and black hole accretion are strongly affected by dust extinction, making far-infrared (far-IR) observations the best way to disentangle and study the co-evolution of galaxies and super massive black holes. The plethora of fine structure lines and emission features from dust, ionised and neutral atomic and warm molecular gas in the rest-frame mid- and far-IR provide unmatched diagnostic power to determine the properties of gas and dust, measure gas-phase…

Quantum trajectory of the one atom maser
The evolution of a quantum system undergoing repeated indirect measurements naturally leads to a Markov chain on the set of states which is called a quantum trajectory. In this paper we consider a specific model of such a quantum trajectory associated to the one-atom maser model. It describes the evolution of one mode of the quantized electromagnetic field in a cavity interacting with two-level atoms. When the system is non-resonant we prove that this Markov chain admits a unique invariant prob…

Introducing cuDisc: a 2D code for protoplanetary disc structure and evolution calculations
We present a new 2D axisymmetric code, cuDisc, for studying protoplanetary discs, focusing on the self-consistent calculation of dust dynamics, grain size distribution and disc temperature. Self-consistently studying these physical processes is essential for many disc problems, such as structure formation and dust removal, given that the processes heavily depend on one another. To follow the evolution over substantial fractions of the disc lifetime, cuDisc uses the CUDA language and libraries t…

New perspectives on future rip scenarios with holographic dark energy
We explore the asymptotic future evolution of holographic dark energy (HDE) models, in which the density of the dark energy is a function of a cutoff scale $L$. We develop a general methodology to determine which models correspond to future big rip, little rip, and pseudo-rip (de Sitter) evolution, and we apply this methodology to a variety of well-studied HDE models. None of these HDE models display little rip evolution, and we are able to show, under very general assumptions, that HDE models …

Towards a sharper phase-field method: a hybrid diffuse-semisharp approach for microstructure evolution problems
A new approach is developed for computational modelling of microstructure evolution problems. The approach combines the phase-field method with the recently-developed laminated element technique (LET) which is a simple and efficient method to model weak discontinuities using nonconforming finite-element meshes. The essence of LET is in treating the elements that are cut by an interface as simple laminates of the two phases, and this idea is here extended to propagating interfaces so that the vo…

Positive and non-positive measurements in energy extraction from quantum batteries
We extend the concept of stochastic energy extraction from quantum batteries to the scenario where both positive operator-valued (POV) and physically realizable non-positive operator-valued measurements are applied (NPOVMs) on the auxiliary connected to the battery in presence of noise. The process involves joint evolution of the battery and the auxiliary for a particular time interval, an interaction of the auxiliary with its environment which induces noise in the auxiliary, and performing a P…

However, the physical connections between SNe IIP and their progenitor stars remain unclear. This paper presents a comprehensive grid of stellar evolution models and their corresponding supernova light curves (LCs) to investigate the physical properties of observed SNe IIP.

Studying The Effect of Radiation Pressure on Evolution of a Population III Stellar Cluster
Recent numerical simulations have shown that the unstable disk within the central regime of the primordial gas cloud fragments to form multiple protostars on several scales. Their evolution depends on the mass accretion phenomenon, interaction with the surrounding medium and radiative feedback respectively. In this work, we use a fast semi-analytical framework in order to model multiple protostars within a rotating cloud, where the mass accretion is estimated via a Bondi-Hoyle flow and the feed…

Fast neutrino flavor conversions in a supernova: emergence, evolution, and effects
Fast flavor conversions (FFCs) of neutrinos, which can occur in core-collapse supernovae (CCSNe), are multiangle effects. They depend on the angular distribution of the neutrino's electron lepton number (ELN). In this work, we present a comprehensive study of the FFCs by solving the multienergy and multiangle quantum kinetic equations with an extended set of collisional weak processes based on a static and spherically symmetric CCSN matter background profile. We investigate the emergence and ev…

Clustering algorithms or methods for GPS trajectories are in constant evolution due to the interest aroused in part of the scientific community. With the development of clustering algorithms considered traditional, improvements to these algorithms and even unique methods considered as "novelty" for science have emerged. This work aims to analyze the scientific production that exists around the topic "GPS trajectory clustering" by means of bibliometrics. Therefore, a total of 559 articles from t…

Neutrino many-body flavor evolution: the full Hamiltonian
We study neutrino flavor evolution in the quantum many-body approach using the full neutrino-neutrino Hamiltonian, including the usually neglected terms that mediate non-forward scattering processes. Working in the occupation number representation with plane waves as single-particle states, we explore the time evolution of simple initial states with up to $N=10$ neutrinos. We discuss the time evolution of the Loschmidt echo, one body flavor and kinetic observables, and the one-body entanglement…

Optimality conditions for sparse optimal control of viscous Cahn-Hilliard systems with logarithmic potential
In this paper we study the optimal control of a parabolic initial-boundary value problem of viscous Cahn-Hilliard type with zero Neumann boundary conditions. Phase field systems of this type govern the evolution of diffusive phase transition processes with conserved order parameter. It is assumed that the nonlinear functions driving the physical processes within the spatial domain are double-well potentials of logarithmic type whose derivatives become singular at the boundary of their respectiv…

Abstract: This study proposes a methodology using OpenAlex (OA) for tracking Open Access publications in the case of Argentina, a country where a self-archiving mandate has been in effect since 2013 ( Law 26.899, 2013). A sample of 167,240 papers by researchers from the National Council for Scientific and Technical Research (CONICET) was created and analyzed using statistical techniques. We estimate that OA is able to capture between 85-93% of authors for all disciplines, with the exception of Social Sciences and Humanities, where it only reaches an estimated 47%. The availability of papers in Open Access was calculated to be 41% for the period 1953-2021 and 46% when considering exclusively the post-law period (2014-2021). In both periods, gold Open Access made up the most common route. When comparing equal periods post and pre-law, we observed that the upward trend of gold Open Access was pre-existing to the legislation and the availability of closed articles in repositories increased by 5% to what is estimated based on existing trends. However, while the green route has had a positive evolution, it has been the publication in gold journals that has boosted access to Argentine production more rapidly. We concluded that the OA-based methodology, piloted here for the first time, is viable for tracking Open Access in Argentina since it yields percentages similar to other national and international studies.
En este estudio se propone una metodolog\'ia utilizando OpenAlex (OA) para monitorear el acceso abierto (AA) a las publicaciones cient\'ificas para el caso de Argentina, pa\'is donde rige el mandato de autoarchivo -Ley 26.899 (2013)-. Se conform\'o una muestra con 167.240 art\'iculos de investigadores del Consejo Nacional de Investigaciones Cient\'ificas y T\'ecnicas (CONICET) que se analizaron con t\'ecnicas estad\'isticas. Se estim\'o que OA puede representar entre 85-93% de los autores para todas las disciplinas, excepto Ciencias Sociales y Humanidades, donde solo alcanza al 47%. Se calcul\'o que 41% de los art\'iculos publicados entre 1953-2021 incluidos en la fuente est\'an en AA, porcentaje que sube a 46% al considerar exclusivamente el periodo post ley (2014-2021). En ambos periodos es la v\'ia dorada la que representa mayor proporci\'on. Al comparar periodos iguales post y pre ley, se observ\'o que la tendencia en alza de la v\'ia dorada era preexistente a la legislaci\'on y la disponibilidad de art\'iculos cerrados en repositorios aument\'o un 5% a lo que se estima en base a tendencias existentes. Se concluye que si bien la v\'ia verde ha tenido una evoluci\'on positiva, ha sido la publicaci\'on en revistas doradas lo que ha impulsado m\'as r\'apidamente el acceso a la producci\'on argentina. Asimismo, que la metodolog\'ia basada en OA, piloteada aqu\'i por primera vez, es viable para monitorear el AA en Argentina ya que arroja porcentajes similares a otros estudios nacionales e internacionales.

Understanding the impact of messages on agents' opinions over social networks is important. However, to our best knowledge, there has been limited quantitative investigation into this phenomenon in the prior works. To address this gap, this paper proposes the Message-Enhanced DeGroot model. The Bounded Brownian Message model provides a quantitative description of the message evolution, jointly considering temporal continuity, randomness, and polarization from mass media theory.

Localizability in de Sitter space for 2+1 dimensions
We extended the notion of Newton-Wigner localization, already constructed in the bi-dimensional de Sitter space, to the tri-dimensional case for both principal and complementary series. We identify the one-particle subspace, generated by the positive-energy modes solution of the Klein-Gordon equation, as an irreducible representation of the de Sitter group. The time-evolution of the Newton-Wigner operator was obtained explicitly, and for the complementary series the evolution is trivial, i.e., …

Combined magnetic field evolution in neutron star cores and crusts: Ambipolar diffusion, Hall effect and Ohmic dissipation
Neutron star magnetic field evolution is mediated through the Hall effect and Ohmic dissipation in the crust while ambipolar diffusion is taking place in the core. These effects have been studied in detail in either part of the star, however, their combined, simultaneous evolution and interplay has not been explored in detail yet. Here, we present simulation results of the simultaneous evolution of the magnetic field in the core due to ambipolar diffusion and the crust due to Hall effect and Oh…

Evolution equation for quantum coherence
Quantum coherence plays an important role in quantum resource theory, which is strongly related with entanglement. Similar to the entanglement evolution equation, we find the coherence evolution equation of quantum states through fully and strictly incoherent operation (FSIO) channels. In order to quantify the full coherence of qudit states, we define G-coherence and convex roof of G-coherence, and prove that the G-coherence is a strong coherence monotone and the convex roof of G-coherence is a…

In this work, we complete our CT18qed study with the neutron's photon parton distribution function (PDF), which is essential for the nucleus scattering phenomenology. Two methods, CT18lux and CT18qed, based on the LUXqed formalism and the DGLAP evolution, respectively, to determine the neutron's photon PDF have been presented. Various low-$Q^2$ non-perturbative variations have been carefully examined, which are treated as additional uncertainties on top of those induced by quark and gluon PDFs.…
