description: We investigate the scattering of classical and quantum particles in impulsive backgrounds fields. These fields model short outbursts of radiation propagating with the speed of light. The singular nature of the problem will be accounted for by the use of Colombeau's generalized function which however give rise to ambiguities. It is the aim of the paper to show that these ambiguities can be overcome by implementing additional physical conditions, which in the non-singular case would be satisfied automatically. As example we discuss the scattering of classical, Klein-Gordon and Dirac particles in impulsive electromagnetic fields.

description: We show that the Wang-Swendsen-Kotecký algorithm for antiferromagnetic $q$-state Potts models is nonergodic at zero temperature for $q=3$ on periodic $3m \times 3n$ lattices where $m,n$ are relatively prime. For $q \ge 4$ and/or other lattice sizes or boundary conditions, the ergodicity at zero temperature is an open question.

The Jets and and Supercritical Accretion Disk in SS433
Creators: name: Fabrika, Sergei
Publisher: name: arXiv
Year: 2006
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: (abridged) The review describes observations of SS433. The main difference between SS433 and other X-ray binaries is the supercritical regime for the gas accretion onto the relativistic star (most likely a black hole), which has lead to the formation of collimated relativistic jets. The properties of the jets are determined by their interaction with the disk wind. The precession of the disk and jets, as well as the eclipsing in the binary system, make SS433 a unique laboratory for studies of mechanisms for the microquasar phenomenon. Essentially all photometric and spectroscopic properties of SS433 are determined by the accretion disk and its orientation, but the disk itself is not observed, being located beneath the photosphere of the dense wind. Observational manifestations of the wind and of gas flows in the system are described. Little is known about the structure of the central regions where the hot bases of the jets are located. The available X-ray, UV, and optical observations point towards the picture where the bases of the jets are surrounded by cocoons of hot gas reradiating emission from the inner regions of the jet channel. Direct investigations of this channel in the supercritical accretion disk of SS433 are not possible; however, a similar object oriented face-on would likely be an extremely bright X-ray source, such as ultra-luminous X-ray sources observed in other galaxies.

description: Representation theory provides a suitable framework to count and classify invariants in tensor models. We show that there are two natural ways of counting invariants, one for arbitrary rank of the gauge group and a second, which is only valid for large N. We construct bases of invariant operators based on the counting, and compute correlators of their elements. The basis associated with finite N diagonalizes the two-point function of the theory and it is analogous to the restricted Schur basis used in matrix models. We comment on future lines of investigation.

description: This paper develops new solution procedures for the order picker routing problem in U-shaped order picking zones with a movable depot, which has so far only been solved using simple heuristics. The paper presents the first exact solution approach, based on combinatorial Benders decomposition, as well as a heuristic approach based on dynamic programming that extends the idea of the venerable sweep algorithm. In a computational study, we demonstrate that the exact approach can solve small instances well, while the heuristic dynamic programming approach is fast and exhibits an average optimality gap close to zero in all test instances. Moreover, we investigate the influence of various storage assignment policies from the literature and compare them to a newly derived policy that is shown to be advantageous under certain circumstances. Secondly, we investigate the effects of having a movable depot compared to a fixed one and the influence of the effort to move the depot.

description: This paper investigates the possibility of improving radio interferometric images using an algorithm inspired by an optical method known as "lucky imaging", which would give more weight to the best-calibrated visibilities used to make a given image. A fundamental relationship between the statistics of interferometric calibration solution residuals and those of the image-plane pixels is derived in this paper. This relationship allows us to understand and describe the statistical properties of the residual image. In this framework, the noise-map can be described as the Fourier transform of the covariance between residual visibilities in a new differential Fourier plane. Image-plane artefacts can be seen as one realisation of the pixel covariance distribution, which can be estimated from the antenna gain statistics. Based on this relationship, we propose a means of improving images made with calibrated visibilities using weighting schemes. This improvement would occur after calibration, but before imaging - it is thus ideally used between major iterations of self-calibration loops. Applying the weighting scheme to simulated data improves the noise level in the final image at negligible computational cost.

description: Property of charged fermion states is investigated in the quenched U(1) chiral Wilson-Yukawa model. Fitting the charged fermion propagator with a single hyperbolic cosine does not yield reliable results. On the other hand the behavior of the propagator including large lattice size dependence is well described by the large Wilson-Yukawa coupling expansion, providing strong evidence that no charged fermion state exists as an asymptotic particle in this model.

description: Student housing satisfaction through research studies has been found to be influenced by many indicators. As more provisions are being put in place to increase the availability of student housing within the urban context, it is also important to understand the dynamics behind this phenomenon. In this way, significant contributions are made in both the practical and academic domains. The study therefore investigated the main predictors influencing housing satisfaction among international students in Leibniz University of Hannover, living in state managed accommodation. With a growing international student population in the city, understanding these factors is crucial for urban development planning and enhancing the quality of student life. The research study employed a combination of descriptive analysis, correlation and regression analyses to identify the housing attributes significantly impacting students' overall satisfaction. The findings from the correlation analysis revealed that 12 indicators (safety, infrastructure quality, environmentally friendly, staff performance, housing sustainability, recreational quality, amenities, management response, privacy level, air quality, recommendation and continue stay) were the most significant predictors of student housing satisfaction. The research contributes to existing literature by providing empirical evidence on the specific factors/variables that affect international students' housing satisfaction in Hannover. The results highlight the importance of safety, quality infrastructure, neighbourhood quality and recreational facilities in student housing policies. The study also highlights the need for environmentally sustainable practices in housing development. This thesis offers valuable insights for university authorities, urban planners, and housing providers, emphasizing the need to focus on key areas to improve international students' housing experiences. It also calls for the need to strategically investigate the housing experiences of students and to involve them in decision making processes. The findings inform targeted strategies and policy recommendations to enhance student housing satisfaction. This ultimately contributes to the well-being of students, as well as improves urban living among residents in the city of Hannover.
3D simulations of rising magnetic flux tubes in a compressible rotating interior: The effect of magnetic tension

description: Context: Long-term variability in solar cycles represents a challenging constraint for theoretical models. Mean-field Babcock-Leighton dynamos that consider non-instantaneous rising flux tubes have been shown to exhibit long-term variability in their magnetic cycle. However a relation that parameterizes the rise-time of non-axisymmetric magnetic flux tubes in terms of stellar parameters is still missing. Aims: We aim to find a general parameterization of the rise-time of magnetic flux tubes for solar-like stars. Methods: By considering the influence of magnetic tension on the rise of non-axisymmetric flux tubes, we predict the existence of a control parameter referred as $Γ_{α_1}^{α_2}$. This parameter is a measure of the balance between rotational effects and magnetic effects (buoyancy and tension) acting on the magnetic flux tube. We carry out two series of numerical experiments (one for axisymmetric rise and one for non-axisymmetric rise) and demonstrate that $Γ_{α_1}^{α_2}$ indeed controls the rise-time of magnetic flux tubes. Results: We find that the rise-time follows a power law of $Γ_{α_1}^{α_2}$ with an exponent that depends on the azimuthal wavenumber of the magnetic flux loop. Conclusions: Compressibility does not impact the rise of magnetic flux tubes, while non-axisymmetry does. In the case of non-axisymmetric rise, the tension force modifies the force balance acting on the magnetic flux tube. We identified the three independent parameters required to predict the rise-time of magnetic flux tubes, that is, the stellar rotation rate, the magnetic flux density of the flux tube, and its azimuthal wavenumber. We combined these into one single relation that is valid for any solar-like star. We suggest using this generalized relation to constrain the rise-time of magnetic flux tubes in Babcock-Leighton dynamo models.

description: This study investigates the long-term effects of mRNA vaccines on immune memory and public health outcomes in Ghana between 2020 and 2024, addressing a critical gap in understanding the durability of vaccine-induced immunity amid evolving COVID-19 variants. As global attention turns toward sustainable vaccination strategies, the importance of evaluating immunological persistence and socio-behavioral influences becomes imperative, especially in low- and middle-income settings. The research employed a quantitative-descriptive design using secondary data from 10,880 participants drawn from national health registries. Statistical methods including paired t-tests, Pearson correlations, and multiple regression analyses were applied to evaluate antibody decline, vaccine uptake trends, misinformation exposure, and hospitalization rates. Findings revealed a significant drop in average antibody titers from 1,625 to 830 AU/mL within 12 months (p < 0.001), especially among immunocompromised and rural populations. A strong negative correlation (r = -0.952) between vaccine coverage and hospitalizations affirmed the public health impact, while a Chi-square test (χ² = 146.29, p < 0.001) linked high misinformation exposure to increased hesitancy. The regression model (R² = 0.814) demonstrated that vaccine coverage (β = -0.72), booster uptake (β = -0.65), and misinformation (β = 0.61) significantly predicted new case trends. Overall correlation with public health indicators was r = -0.88. These results suggest mRNA vaccines remain effective but require ongoing booster strategies and behavioral interventions. The findings underscore the need for policy shifts towards tailored booster schedules, digital health campaigns, and equitable vaccine distribution to enhance immune memory and pandemic resilience in Ghana.

The observations for the Antlia project consist of Washington wide-field images taken with the MOSAIC camera mounted at the prime focus of the CTIO 4-m Blanco telescope. Our preliminary results correspond to the identification and classification of dwarf galaxies in the central cluster region, extending the list of Ferguson & Sandage (1990). The final aim of our project is to study the luminosity function, morphology and structural parameters of dwarf galaxies in the Antlia cluster with a more complete sample.

description: We discuss information-theoretic properties of low-energy photons and gravitons in the S-matrix. Given an incoming n-particle momentum eigenstate, we demonstrate that unobserved soft photons decohere nearly all outgoing momentum superpositions of charged particles, while the universality of gravity implies that soft gravitons decohere nearly all outgoing momentum superpositions of all the hard particles. Using this decoherence, we compute the entanglement entropy of the soft bosons and show that it is infrared-finite when the leading divergences are re-summed a la Bloch and Nordsieck.

description: Colloidal particles at complex fluid interfaces and within films assemble to form ordered structures with high degrees of symmetry via interactions that include capillarity, elasticity, and other fields like electrostatic charge. Here we study microparticle interactions within free-standing smectic-A films, in which the elasticity arising from the director field distortion and capillary interactions arising from interface deformation compete to direct the assembly of motile particles. New colloidal assemblies and patterns, ranging from 1D chains to 2D aggregates, sensitive to the initial wetting conditions of particles at the smectic film, are reported. This work paves the way to exploiting LC interfaces as a means to direct spontaneously formed, reconfigurable, and optically active materials.

description: An idealized multigrid algorithm for the computation of propagators of staggered fermions is investigated. Exemplified in four-dimensional $SU(2)$ gauge fields, it is shown that the idealized algorithm preserves criticality under coarsening. The same is not true when the coarse grid operator is defined by the Galerkin prescription. Relaxation times in computations of propagators are small, and critical slowing is strongly reduced (or eliminated) in the idealized algorithm. Unfortunately, this algorithm is not practical for production runs, but the investigations presented here answer important questions of principle.

description: The spin polarization of electrons from multiphoton ionization of Xe by 395 nm circularly polarized laser pulses at $6\cdot10^{13}$ W/cm$^2$ has been measured. At this photon energy of 3.14 eV the above threshold ionization peaks connected to Xe$^+$ ions in the ground state ($J=3/2$, ionization potential $I_p=12.1$ eV) and the first exicted state ($J=1/2$, $I_p=13.4$ eV) are clearly separated in the electron energy distribution. These two combs of ATI peaks show opposite spin polarizations. The magnitude of the spin polarization is a factor of two higher for the $J=1/2$ than for the $J=3/2$ final ionic state. In turn the data show that the ionization probability is strongly dependent on the sign of the magnetic quantum number.

description: In the next several years we will see an increasing number of divestment campaigns spring up among student bodies nationwide. Given this trend, I believe it would be helpful to those interested in divestment at U.Va and other institutions to first examine the discussion that has followed the campaign so far. What is divestment? Is it well argued? Does it make economic sense? Should we divest? If so, what steps should we take? Frequent campaign failures indicate that the divestment argument needs some reworking. The ultimate objectives of this paper are 1) a new argument that elucidates more compelling incentives for U.Va to take action against fossil fuels and 2) a financially responsible reinvestment strategy that reflects the greater values of our university.

description: We present the orbital solution for the newly discovered transient Be X-ray binary Swift J0243.6+6124 based on the data from gamma-ray burst monitor onboard Fermi obtained during the Oct 2017 outburst. We model the Doppler induced and intrinsic spin variations of the neutron star assuming that the later is driven by accretion torque and discuss the implications of the observed spin variations for the parameters of the neutron star and the binary. In particular we conclude that the neutron star must be strongly magnetized, and estimate the distance to the source at $\sim$5 kpc.

description: A sample of 109 type Ia supernovae (SNe Ia) with recession velocity < 30,000 km s^{-1}, is compiled from published SNe Ia light curves to explore the expansion rate of the local Universe. Based on the color parameter delta C_{12} and the decline rate delta m_{15}, we found that the average absorption to reddening ratio for SN Ia host galaxies to be R_{UBVI} = 4.37+/-0.25, 3.33+/-0.11, 2.30+/-0.11, 1.18+/-0.11, which are systematically lower than the standard values in the Milky Way. We investigated the correlations of the intrinsic luminosity with light curve decline rate, color index, and supernova environmental parameters. In particular, we found SNe Ia in E/S0 galaxies to be brighter close to the central region than those in the outer region, which may suggest a possible metallicity effect on SN luminosity. The dependence of SN luminosity on galactic environment disappears after corrections for the extinction and delta C_{12}. The Hubble diagrams constructed using 73 Hubble flow SNe Ia yield a 1-sigma scatter of <0.12 mag in BVI bands and ~0.16 mag in U band. The luminosity difference between normal SNe Ia and peculiar objects (including SN 1991bg-like and 1991T-like events) has now been reduced to within 0.15 mag via delta C_{12} correction. We use the same precepts to correct the nearby SNe Ia with Cepheid distances and found that the fully corrected absolute magnitudes of SNe Ia are: M_{B} = -19.33+/-0.06 mag, M_{V} = -19.27+/-0.05 mag. We deduced a value for the Hubble constant of H_{0} = 72 +/- 6 (total) km s^{-1} Mpc^{-1}.

description: How cells correct deviations from a mean cell size at mitosis remains uncertain. Classical cell-size homeostasis models are the sizer, timer, and adder [1]. Sizers postulate that cells divide at some threshold size; timers, that cells grow for a set time; and adders, that cells add a constant volume before division. Here, we show that a size-based probabilistic model of cell-size control at the G2/M transition (P(Div)) can generate realistic cell-size homeostasis in silico. In fission yeast cells, Cyclin BCdc13 scales with size, and we propose that this increases the likelihood of mitotic entry, while molecular noise in its expression adds a probabilistic component to the model. Varying Cdc13 expression levels exogenously using a newly developed tetracycline inducible promoter shows that both the level and variability of its expression influence cell size at division. Our results demonstrate that as cells grow larger, their probability of dividing increases, and this is sufficient to generate cell-size homeostasis. Size-correlated Cdc13 expression forms part of the molecular circuitry of this system.

description: Renormalization of Landau level energies in graphene in strong magnetic field due to Coulomb interaction is studied theoretically, and calculations are compared with two experiments on carrier-density dependent scanning tunneling spectroscopy. An approximate preservation of the square-root dependence of the energies of Landau levels on their numbers and magnetic field in the presence of the interaction is examined. Many-body calculations of the renormalized Fermi velocity with the statically screened interaction taken in the random-phase approximation show good agreement with both experiments. The crucial role of the screening in achieving quantitative agreement is found. The main contribution to the observed rapid logarithmic growth of the renormalized Fermi velocity on approach to the charge neutrality point turned out to be caused not by mere exchange interaction effects, but by weakening of the screening at decreasing carrier density. The importance of a self-consistent treatment of the screening is also demonstrated.

description: As part of the European Data Strategy towards establishing a Single EU Market for data, the European Commission is working on common European data spaces including a Green Deal Data Space (GDDS) that covers issues such as climate change, circular economy, pollution, biodiversity and deforestation. The successful development of the EU GDDS will depend on the availability of FAIR (findable, accessible, interoperable and reusable) data sources, including FAIR volunteered geographic information and citizen science data.

Active citizen engagement in science is now one of the European Research Area priority actions, as defined in the Pact for Research and Innovation (R&I) in Europe. The Open Science Policy of the European Commission recognises Citizen Science as one of its eight policy ambitions, stating that “the general public should be able to make significant contributions and be recognised as valid European science knowledge producers”.

This document is the Deliverable 2.3 for the AD4GD project. It presents the results achieved in the context of Task 2.2 “Identification of CitSci data including complementary socioeconomic and INSPIRE data” as part of Work Package 2 “In-situ networks, CitSci and Socioeconomic Data”. The reader should consider that a follow-up version of this document will be released on month 30 of the project as Deliverable 2.4.

This document offers a review of the current state of play with citizen science data in regard to FAIR compliance. It highlights citizen science initiatives that successfully apply open standards and tools to collect and share data that closely align with FAIR data principles and is a potential candidate for the inclusion into the EU GDDS. It examines platforms and tools that can support citizen science projects and discusses gaps that still exist to achieve citizen science data FAIRness.

description: Purpose: Exposure to ionizing radiation causes damage to the genomic integrity and stability of the cell. Though a large number of molecules have been studied for their radioprotective capability, no single agent is available today that meets all the requirements of a good radiprotector. In this study, we have investigated a combination of Resveratrol (RSV) and 3,3′-Diindolyl methane (DIM) for its efficacy for radioprotection. It is our hypothesis that this combination that possesses less toxicity than synthetic compounds, free radical scavenging potential, and the capacity to interfere with the several of the signaling cascades that trigger damage to cell by ionizing radiation may possess good radioprotective capability. Materials and methods: Mice were pre-treated with a combination of RSV and DIM and the 30-day mortality assay, endogenous antioxidant levels in intestinal mucosa, metaphase chromosomal aberrations, and micronuclei formation were assessed after exposed to ionizing radiation. Results: The dose modifying factor (DRF) obtained for RSV, DIM, and the combination is 1.15, 1.17, and 1.3, respectively. Pre-treatment of mice with the combination results in significant (***p = .001) protection of the endogenous antioxidant levels, chromosomal aberrations, micronuclei formation, after exposure to ionizing radiation. Conclusions: Our findings suggest that pre-treatment with the combination of RSV and DIM protects effectively from the ionizing radiation-induced damage at the molecular, cellular, and tissue levels by counteracting both the direct and indirect effects.

description: The phenotypic adjustments of Mycobacterium tuberculosis are commonly inferred from the analysis of transcript abundance. While mechanisms of transcriptional regulation have been extensively analysed in mycobacteria, little is known about mechanisms that shape the transcriptome by regulating RNA decay rates. The aim of the present study is to identify the core components of the RNA degradosome of M. tuberculosis and to analyse their function in RNA metabolism. Using an approach involving cross-linking to 4-thiouridine-labelled RNA, we mapped the mycobacterial RNA-bound proteome and identified degradosome-related enzymes polynucleotide phosphorylase (PNPase), ATP-dependent RNA helicase (RhlE), ribonuclease E (RNase E) and ribonuclease J (RNase J) as major components. We then carried out affinity purification of eGFP-tagged recombinant constructs to identify protein-protein interactions. This identified further interactions with cold-shock proteins and novel KH-domain proteins. Engineering and transcriptional profiling of strains with a reduced level of expression of core degradosome ribonucleases provided evidence of important pleiotropic roles of the enzymes in mycobacterial RNA metabolism highlighting their potential vulnerability as drug targets.

description: Pelletization of the loose rice straw is an attractive option to produce renewable fuels. In this paper, we focus on the problem of how to improve this pelletization process, especially to reduce energy consumption and improve product quality. In detail, we first pretreat rice straw, and then investigate the densification characteristics of the pretreated materials. Pretreatment methods of the materials include hydrothermal treatment and adding a certain proportion of economic additives, such as rapeseed meal and waste engine oil respectively. In addition, the pretreated rice straw was pelletized by using a biomass densification platform, meanwhile energy consumption and pellet quality were tested. Experimental results indicate that the hydrothermal pretreatment played an important role in reducing energy consumption and improving the product quality, and waste engine oil has a better effect than the rapeseed meal. We also observe that the obtained pellet quality reaches the standard of middle-grade coal, and the proposed pretreatment method realizes the comprehensive utilization of waste agricultural resources.
