Relativistic Causality vs. No-Signaling as the limiting paradigm for correlations in physical theories

description: The no-signaling constraints state that the probability distribution of the outputs of any subset of parties is independent of the inputs of the complementary set; here we re-examine these to see how they arise from relativistic causality. We show that while the usual no-signaling constraints are sufficient, in general they are not necessary to ensure that a theory does not violate causality. Depending on the exact space-time coordinates of the measurement events in a multi-party Bell experiment, causality only imposes a subset of the usual no-signaling conditions. After revisiting the derivation of the two-party no-signaling constraints, we consider the three-party Bell scenario and characterise a space-time region in which a subset of the no-signaling conditions is sufficient to preserve causality. Secondly, we examine the implications for device-independent cryptography against an eavesdropper constrained only by the laws of relativity. We show an explicit attack in certain measurement configurations on a family of protocols based on the n-party Mermin inequalities that were previously proven secure under the old no-signaling conditions. We then show that security of two-party protocols can also be compromised when the eavesdropper's measurement configuration is not constrained. The monogamy of non-local correlations that underpin their use in secrecy can also be broken in certain space-time configurations. Thirdly, we inspect the notion of free-choice and propose a definition of free-choice in the multi-party Bell experiment. We then re-examine the question whether quantum correlations may admit explanations by finite speed superluminal influences. Finally, we study genuine multiparty non-locality and present a new class of causal bilocal models. We propose a new Svetlichny-type inequality that is satisfied by the causal bilocal model and show its violation within quantum theory.

description: The interactions and synchronization of two parallel and slender flags in a uniform axial flow are studied in the present paper by generalizing Lighthill's Elongated Body Theory (EBT) and Lighthill's Large Amplitude Elongated Body Theory (LAEBT) to account for the hydrodynamic coupling between flags. The proposed method consists in two successive steps, namely the reconstruction of the flow created by a flapping flag within the LAEBT framework and the computation of the fluid force generated by this nonuniform flow on the second flag. In the limit of slender flags in close proximity, we show that the effect of the wakes have little influence on the long time coupled-dynamics and can be neglected in the modeling. This provides a simplified framework extending LAEBT to the coupled dynamics of two flags. Using this simplified model, both linear and large amplitude results are reported to explore the selection of the flapping regime as well as the dynamical properties of two side-by-side slender flags. Hydrodynamic coupling of the two flags is observed to destabilize the flags for most parameters, and to induce a long-term synchronization of the flags, either in-phase or out-of-phase.

description: A result of Haglund implies that the $(q,t)$-bigraded Hilbert series of the space of diagonal harmonics is a $(q,t)$-Ehrhart function of the flow polytope of a complete graph with netflow vector $(-n, 1, \dots, 1)$. We study the $(q,t)$-Ehrhart functions of flow polytopes of threshold graphs with arbitrary netflow vectors. Our results generalize previously known specializations of the mentioned bigraded Hilbert series at $t=1$, $0$, and $q^{-1}$. As a corollary to our results, we obtain a proof of a conjecture of Armstrong, Garsia, Haglund, Rhoades and Sagan about the $(q, q^{-1})$-Ehrhart function of the flow polytope of a complete graph with an arbitrary netflow vector.

description: This paper investigates thin-shell wormholes in Born-Infeld theory supported by generalized Cosmic Chaplygin gas (GCCG). We study their stability via radial perturbations for distinct values of charge and Born-Infeld parameter. The comparison of wormhole solutions corresponding to generalized Chaplygin gas, modified Chaplygin gas with GCCG quation of state is established. It is found that similar type of wormhole solutions exists for small value of charge and Born-Infeld parameter for all type of equation of state, while some extra stable as well as unstable solution are found corresponding to large value of charge and Born-Infeld parameter. Thus, it is concluded that GCCG and large value of charge may responsible for such extra solutions.

Specifically we consider bounded solutions to an associated two-dimensional non-Lipschitz non-autonomous dynamical system, for which, we establish the existence of a two-parameter family of homoclinic connections on the origin, and a heteroclinic connection between two equilibrium points. Additionally, we obtain bounds and estimates on the rate of convergence of the homoclinic connections to the origin.

description: AE Aquarii (AE Aqr) is a cataclysmic binary hosting one of the fastest rotating (P$_{\rm spin}$ = 33.08 s) white dwarfs known. Based on seven years of Fermi Large Area Telescope (LAT) Pass 8 data, we report on a deep search for gamma-ray emission from AE Aqr. Using X-ray observations from ASCA, XMM-Newton, Chandra, Swift, Suzaku, and NuSTAR, spanning 20 years, we substantially extend and improve the spin ephemeris of AE Aqr. Using this ephemeris, we searched for gamma-ray pulsations at the spin period of the white dwarf. No gamma-ray pulsations were detected above 3 $σ$ significance. Neither phase-averaged gamma-ray emission nor gamma-ray variability of AE Aquarii is detected by Fermi-LAT. We impose the most restrictive upper limit to the gamma-ray flux from AE Aqr to date: $1.3\times 10^{-12}$ erg cm$^{-2}$ s$^{-1}$ in the 100 MeV-300 GeV energy range, providing constraints on models.

description: A number of electronic devices involve metal/oxide interfaces in their structure where the oxide layer plays the role of electrical insulator. As the downscaling of devices continues, the oxide thickness can spread over only a few atomic layers, making the role of interfaces prominent on its insulating properties. The prototypical Al/SiO2 metal/oxide interface is investigated using first principle calculations, and the effect of the interfacial atomic bonding is evidenced. It is shown that the interface bonding configuration critically dictates the mechanical and electronic properties of the interface. Oxygen atoms are found to better delimit the oxide boundaries than cations. Interfacial cation-metal bonds allow the metal potential to leak inside the oxide layer, without atomic diffusion, leading to a virtual oxide thinning.

description: Methicillin-resistant Staphylococcus aureus (MRSA) is a difficult-to-treat infection that only in the European Union affects about 150,000 patients and causes extra costs of 380 million Euros annually to the health-care systems. Increasing efforts have been taken to mitigate the epidemics and to avoid potential outbreaks in low endemic settings. Understanding the population dynamics of MRSA through modeling is essential to identify the causal mechanisms driving the epidemics and to generalize conclusions to different contexts. We develop an innovative high-resolution spatiotemporal contact network model of interactions between patients to reproduce the hospital population in the context of the Stockholm County in Sweden and simulate the spread of MRSA within this population. Our model captures the spatial and temporal heterogeneity caused by human behavior and by the dynamics of mobility within wards and hospitals. We estimate that in this population the epidemic threshold is at about 0.008. We also identify that these heterogeneous contact patterns cause the emergence of super-spreader patients and a polynomial growth of the epidemic curve. We finally study the effect of standard intervention control strategies and identify that screening is more effective than improved hygienic in order to cause smaller or null outbreaks.

description: Presolar grains constitute remnants of stars that existed before the formation of the solar system. In addition to providing direct information on the materials from which the solar system formed, these grains provide ground-truth information for models of stellar evolution and nucleosynthesis. Here we report the in-situ identification of two unique presolar graphite grains from the primitive meteorite LaPaz Icefield 031117. Based on these two graphite grains, we estimate a bulk presolar graphite abundance of 5(-3)(+7) ppm in this meteorite. One of the grains (LAP-141) is characterized by an enrichment in 12C and depletions in 33,34S, and contains a small iron sulfide subgrain, representing the first unambiguous identification of presolar iron sulfide. The other grain (LAP-149) is extremely 13C-rich and 15N-poor, with one of the lowest 12C/13C ratios observed among presolar grains. Comparison of its isotopic compositions with new stellar nucleosynthesis and dust condensation models indicates an origin in the ejecta of a low-mass CO nova. Grain LAP-149 is the first putative nova grain that quantitatively best matches nova model predictions, providing the first strong evidence for graphite condensation in nova ejecta. Our discovery confirms that CO nova graphite and presolar iron sulfide contributed to the original building blocks of the solar system.

description: Using a photonic reformatter to eliminate the effects of conventional modal noise could greatly improve the stability of a high resolution spectrograph. However the regimes where this advantage becomes clear are not yet defined. Here we will look at where modal noise becomes a problem in conventional high resolution spectroscopy and what impact photonic spectrographs could have. We will theoretically derive achievable radial velocity measurements to compare photonic instruments and conventional ones. We will discuss the theoretical and experimental investigations that will need to be undertaken to optimize and prove the photonic reformatting concept.

Influencia de Algunos Parámetros sobre la Selectividad durante el Secado Convectivo de una Mezcla Ternaria

description: Se realizó un estudio experimental de algunos parámetros que tienen influencia sobre la selectividad durante el secado convectivo de una mezcla ternaria líquida y contenida en un sólido poroso. La mezcla ternaria agua-etanol-etil acetato contenida en un lecho de esferas de vidrio de 0.5 cm de diámetro se utilizó como un modelo físico de la representación de unaestructura sólida porosa. Se realizaron experimentos conteniendo carbohidratos disueltos. Se determinó la curva de selectividad cero del etanol. Los experimentos se realizarón bajo un régimen de secado moderado. El incremento de la temperatura del líquido hace que el proceso sea menos selectivo debido a que se inducen velocidades de evaporación mayores. La selectividad del proceso es influenciada en menor grado por el aumento de la velocidad del gas. Cuando se agrega un carbohidrato se observó que se forma una película en las superficies del líquido y el sólido teniendo ésta influencia sobre la evaporación de los solventes y consecuentemente sobre la selectividad. Los experimentos rnuestran que a pesar de las bajas velocidades de evaporación el sólido inerte ejerce influencia no sólo en la transferencia de masa sino que también en la transferencia de calor, haciéndose el proceso menos selectivo en presencia del sólido. Los cálculos de las selectivìdades instantaneas revelan que el sistema agua-etanol-etil acetato presenta un posible azeotropo dinámico cuando la evaporación es en un gas puro. Se realizaron experimentos a concentraciones alrededor del punto azeotrópico calculado para localizar la posición del azeotropo revelando que el comportamiento es similar al esperado en el punto azeotrópico.

description: Hydrogen intercalation in solids is common, complicated, and very difficult to monitor. In a new approach to the problem, we have studied the profile of hydrogen diffusion in single-crystal nanobeams and plates of VO2, exploiting the fact that hydrogen doping in this material leads to visible darkening near room temperature connected with the metal-insulator transition at 65 °C. We observe hydrogen diffusion along the rutile c-axis but not perpendicular to it, making this a highly one-dimensional diffusion system. We obtain an activated diffusion coefficient, ~0.01 e^(-0.6 eV/k_B T) cm2sec-1, applicable in metallic phase. In addition, we observe dramatic supercooling of the hydrogen-induced metallic phase and spontaneous segregation of the hydrogen into stripes implying that the diffusion process is highly nonlinear, even in the absence of defects. Similar complications may occur in hydrogen motion in other materials but are not revealed by conventional measurement techniques.

description: Wet particle separation is widely used in mineral processing and plastic recycling to separate mixtures of particulate materials into further usable fractions due to density differences. This work presents efforts aiming to numerically analyze the wet separation of particles with different densities. In the current study the discrete element method (DEM) is used for the solid phase while the smoothed particle hydrodynamics (SPH) is used for modeling of the liquid phase. The two phases are coupled by the use of a volume averaging technique. In the current study, simulations of spherical particle separation were performed. In these simulations, a set of generated particles with two different densities is dropped into a rectangular container filled with liquid. The results of simulations with two different mixtures of particles demonstrated how separation depends on the densities of particles.

description: Life insurance plays a crucial role in financial planning, providing individuals with security and risk protection. This study explores consumer awareness and perception towards LIC’s individual life insurance plans in Coimbatore City. The research aims to assess the level of awareness among consumers, evaluate their perceptions, and identify key factors influencing their decision-making. A structured questionnaire was used to collect data from LIC policyholders and potential customers in Coimbatore. Statistical analyses, including descriptive statistics, chi-square tests, ANOVA, and regression analysis, were conducted to derive insights. The findings indicate that while many consumers recognize LIC as a trusted insurance provider, gaps exist in their understanding of specific policies, benefits, and terms. Consumer perception is significantly influenced by factors such as brand trust, policy features, premium affordability, and agent recommendations. The study also highlights the most preferred LIC plans and suggests strategies to enhance consumer awareness and satisfaction. The results provide valuable insights for LIC and insurance marketers to develop targeted awareness campaigns and improve policyholder engagement.

description: There is a current surge of interest in using synthetic biology for biotechnology applications. Metabolic engineers, for example, are interested in synthetic biology for its modular and well characterized transcriptional “parts”, such as synthetic gene promoters and terminators, which enable fine tuning in metabolic pathway optimization. Likewise, emerging gene editing methods, such as CRISPR-Cas9, are enabling quicker and more precise genomic integrations. Using both of these advances, there is an increase in the throughput for which altered pathway conditions can be screened. While some advances are being made, there are still several technological gaps, especially for eukaryotic yeast hosts. Therefore, this dissertation work focused on developing engineering methodologies for the yeast Saccharomyces cerevisiae to expand capacity in each of these areas. There were three main areas explored in this work. First, we developed a method for synthetic promoter design which establishes de novo upstream activating sequences (UAS) capable of regulating gene expression by growth phase. These UAS elements, discovered through a transcriptome mining approach, show an over 30-fold activation of a core promoter with completely synthetic designs. Secondly, we improved synthetic terminator design, whereby both minimal synthetic terminators and larger native terminators were improved by adjusting nucleosome occupancy in adjacent sequence space. Using this methodology, de novo synthetic terminators were designed for increased termination efficiency. Lastly, we developed a method for guide RNA expression in yeast organisms using T7 RNA polymerase in vivo. This method allowed guide RNA expression to be exportable across yeast hosts and enabled more complex regulation designs, such as dCas9 logic gates. Together, these approaches improved synthetic promoter design, synthetic terminator design, and guide RNA expression regulation in ways that both complement current ongoing research in S. cerevisiae and enable a generalized approach to be established for other yeast organisms.

In ecology, unconstrained and constrained ordination are popular methods to analyze and visualize multivariate data, with principal components analysis (PCA) and redundancy analysis (RDA) as prototype methods. Constraints give more insight and power by focusing on the response of the variables to particular external predictors or experimental factors, after optional adjustment for covariates. In chemometrics, analysis of variance - simultaneous component analysis (ASCA) was proposed decades later, with particular emphasis on the multivariate main and interaction effects in factorial experiments. This paper shows the similarities and differences between ASCA, its extensions, and (partial) RDA, alias reduced-rank regression. ASCA and RDA (understood as a sequence of partial RDAs, just as ASCA uses a sequence of PCAs) are shown to be mathematically identical for equireplicated designed experiments. Differences appear with unequal replication. As a corollary we show that, with equal replication, a particularly attractive form of ASCA, which displays a main effect together with an interaction, is a special case of principal response curve analysis. RDA is a least-squares method and uses the optimal weights in the dimension reduction of the treatment effects, whereas ASCA extensions for unbalanced data use alternative, sub-optimal weights.

description: Previous studies have discovered a population of small granules with diameters less than 800 km showing differing physical properties. High resolution simulations and observations of the solar granulation, in combination with automated segmentation and tracking algorithms, allow us to study the evolution of the structural and physical properties of these granules and surrounding vortex motions with high temporal and spatial accuracy. We focus on the dynamics of granules (lifetime, fragmentation, size, position, intensity, vertical velocity) over time and the influence of strong vortex motions. Of special interest are the dynamics of small granules compared to regular-sized granules. We developed a temporal tracking algorithm based on our developed segmentation algorithm for solar granulation. This was applied to radiation hydrodynamics simulations and high resolution observations of the quiet Sun by SUNRISE/IMaX. The dynamics of small granules differ in regard to their diameter, intensity and depth evolution compared to regular granules. The tracked granules in the simulation and observations reveal similar dynamics (lifetime, evolution of size, vertical velocity and intensity). The fragmentation analysis shows that the majority of granules in simulations do not fragment, while the opposite was found in observations. Strong vortex motions were detected at the location of small granules. Regions of strong vertical vorticity show high intensities and downflow velocities, and live up to several minutes. The analysis of granules separated according to their diameter in different groups reveals strongly differing behaviors. The largest discrepancies can be found within the groups of small, medium-sized and large granules and have to be analyzed independently. The predominant location of vortex motions on and close to small granules indicates a strong influence on the dynamics of granules.
Quantum nonlinear dynamics of optomechanical systems in the strong coupling regime

description: With an increasing coupling between light and mechanics, nonlinearities begin to play an important role in optomechanics. We solve the quantum dynamics of an optomechanical system in the multi-photon strong coupling regime retaining nonlinear terms. This is achieved by performing a Schrieffer-Wolff transformation on the Hamiltonian including driving terms. The approach is valid away from the red- and blue-sideband drive. We show that the mechanical resonator displays self-sustained oscillations in regimes where the linearized model predicts instabilities, and that the amplitude of these oscillations is limited by the nonlinear terms. Related oscillations of the photon number are present due to frequency mixing of the shifted mechanical and cavity frequencies. This leads to additional peaks in the cavity's power spectral density. Furthermore, we show that it is possible to create phonon states with sub-Poissonian statistics when the system is red-detuned. This result is valid even with strong driving and with initial coherent states.

description: Ausgehend von einem akuten, sich absehbar weiterhin zuspitzenden Lehrer:innenmangel hat die Ständige Wissenschaftliche Kommission (SWK) der Kultusministerkonferenz (KMK) ein Positionspapier veröffentlicht, in welchem eine Reihe von Empfehlungen vorgestellt werden, um eine flächendeckende Absicherung des Unterrichts in Deutschland zu gewährleisten. (Nicht nur) aus einer Perspektive der beruflichen Bildung stellen sich diese Vorschläge als weitgehend kontraproduktiv dar. Im vorliegenden Aufsatz wird zentral analysiert, auf welche Belege die SWK ihre Empfehlungen abstützt und wie sie diese genau begründet. Dabei wird offengelegt, dass einige Empfehlungen überhaupt nicht wissenschaftlich hinterlegt sind und sich dort, wo Belege eingebracht werden, häufig Fragen bezüglich deren Einschlägigkeit und Tragfähigkeit aufwerfen. Insgesamt zeigt sich, dass die Empfehlungen der Ständigen Wissenschaftlichen Kommission der KMK zum Umgang mit dem akuten Lehrkräftemangel die Problemlage kaum ursächlich und nur einseitig (bezogen auf das Lehrpersonal) beleuchten und ohne wissenschaftliche Fundierung überwiegend Maßnahmen empfehlen, die in ihrer Umsetzung geringes Ressourcenpotenzial, jedoch großes Konfliktpotenzial aufweisen. Dem gegenübergestellt werden Überlegungen zur Studien- und Arbeitsmotivation von Lehrkräften und ein Blick auf die Bildungsfinanzierung geworfen, um aufzuzeigen, wo mögliche Ursachen des Lehrkräftemangels liegen, was das mit Berufsorientierungen und -wahrnehmungen zu tun hat und wie man hier möglicherweise konstruktiv und nachhaltig weiterkommen könnte.

description: History in an academic setting is a story mostly told through the written word. But what happens when the story you are trying to tell has you reading in between the lines? In the history of science, women’s contributions were often hidden by a gendered division of labor keeping them from receiving the credit they deserved. The lack of credit left their roles forgotten, which becomes a challenge when understanding the true extent of women’s hidden roles in science. This thesis aims to explore how the gendered division of labor came about in the European history of science which prevented women from receiving recognition for their work. Following a discussion on the history of the division of labor and women in early modern science, as well as the Matthew Effect and Matilda Effect, two case studies are presented on Sophie and Tycho Brahe and Caroline and William Herschel to defend the argument. Additionally, this project was exhibited in the form of a screendance titled I Have a Sister, created with the intention of offering a performative public history example of this analysis to a broader audience.

Medievalism, Hierarchy, and the “Crusader Persona” in 21st Century Christian Nationalism

subject: Alt-Right
subject: Conservatism

description: Christian nationalist sentiment is a product of cultural, political, and economic insecurity. This insecurity arises when the societal status quo shifts and threatens to subvert the “typical” dynamics of power. Confronted with this subversion (or its prospect), traditionally privileged groups seek to preserve the integrity of a system of hierarchies atop which they sit. To do so, they repress progressivism and ostracize societal “others,” whom they perceive as a threat to usurp their own privileged position. Twenty-first century Christian nationalism—especially in the U.S.—employs “weaponized nostalgia” to accomplish this goal. Christian nationalists both inspire mobilization and justify their ideology by likening it to a mythologized version of the past, in which their worldview was still the zeitgeist. This is why Christian nationalists are so drawn to medievalism—it offers a tangible cultural ideal, and its popular portrayals have primed Christian nationalists to believe that the Middle Ages upheld the power dynamics they value. This is done in a manner that is both subconsciously influenced by pop culture medieval fantasy, and that is purposely divorced from the historical context of the “real” Middle Ages so as to better fit the Christian nationalist agenda.

Interplay of Infrared Divergences and Gauge-Dependence of the Effective Potential

description: The perturbative effective potential suffers infrared (IR) divergences in gauges with massless Goldstones in their minima (like Landau or Fermi gauges) but the problem can be fixed by a suitable resummation of the Goldstone propagators. When the potential minimum is generated radiatively, gauge-independence of the potential at the minimum also requires resummation and we demonstrate that the resummation that solves the IR problem also cures the gauge-dependence issue, showing this explicitly in the Abelian Higgs model in Fermi gauge. In the process we find an IR divergence (in the location of the minimum) specific to Fermi gauge and not appreciated in recent literature. We show that physical observables can still be computed in this gauge and we further show how to get rid of this divergence by a field redefinition. All these results generalize to the Standard Model case.

description: Information extraction systems often produce hundreds to thousands of strings on a specific topic. We present a method that facilitates better consumption of these strings, in an exploratory setting in which a user wants to both get a broad overview of what's available, and a chance to dive deeper on some aspects. The system works by grouping similar items together and arranging the remaining items into a hierarchical navigable DAG structure. We apply the method to medical information extraction.

Subjects: subject: Computer Vision and Pattern Recognition (cs.CV)
subject: FOS: Computer and information sciences

description: Monocular depth estimation is an interesting and challenging problem as there is no analytic mapping known between an intensity image and its depth map. Recently there has been a lot of data accumulated through depth-sensing cameras, in parallel to that researchers started to tackle this task using various learning algorithms. In this paper, a deep sparse coding method is proposed for monocular depth estimation along with an approach for deterministic dictionary initialization.

description: For drones, as safety-critical systems, there is an increasing need for onboard detect & avoid (DAA) technology i) to see, sense or detect conflicting traffic or imminent non-cooperative threats due to their high mobility with multiple degrees of freedom and the complexity of deployed unstructured environments, and subsequently ii) to take the appropriate actions to avoid collisions depending upon the level of autonomy. The safe and efficient integration of UAV traffic management (UTM) systems with air traffic management (ATM) systems, using intelligent autonomous approaches, is an emerging requirement where the number of diverse UAV applications is increasing on a large scale in dense air traffic environments for completing swarms of multiple complex missions flexibly and simultaneously. Significant progress over the past few years has been made in detecting UAVs present in aerospace, identifying them, and determining their existing flight path. This study makes greater use of electronic conspicuity (EC) information made available by PilotAware Ltd in developing an advanced collision management methodology -- Drone Aware Collision Management (DACM) -- capable of determining and executing a variety of time-optimal evasive collision avoidance (CA) manoeuvres using a reactive geometric conflict detection and resolution (CDR) technique. The merits of the DACM methodology have been demonstrated through extensive simulations and real-world field tests in avoiding mid-air collisions (MAC) between UAVs and manned aeroplanes. The results show that the proposed methodology can be employed successfully in avoiding collisions while limiting the deviation from the original trajectory in highly dynamic aerospace without requiring sophisticated sensors and prior training.
