description: The properties of the ferromagnetic frustrated spin-S one-dimensional Heisenberg model in the vicinity of the transition point from the ferromagnetic to the singlet ground state is studied using the perturbation theory (PT) in small parameter characterizing the deviation from the transition point. The critical exponents defining the behavior of the ground state energy and spin correlation functions are determined using scaling estimates of infrared divergencies of the PT. It is shown that the quantum fluctuations for $s=1/2$ are sufficiently strong to change the classical critical exponents, while for spin systems with $s\geq 1$ the critical exponents remain classical. The dimerization in the singlet phase near the transition point is discussed.

description: A critical dark matter halo mass ($M_{\rm crit}$) for Population III (Pop III) stars can be defined as the typical minimum halo mass that hosts sufficient cold dense gas required for the formation of the first stars. The presence of Lyman-Werner (UV) radiation, which can dissociate molecular hydrogen, and the baryon-dark matter streaming velocity both delay the formation of Pop III stars by increasing $M_{\rm crit}$. In this work, we constrain $M_{\rm crit}$ as a function of Lyman-Werner flux (including self-shielding), baryon-dark matter streaming, and redshift using cosmological simulations with a large sample of halos utilizing the adaptive mesh refinement (AMR) code ENZO. We provide a fit for $M_{\rm crit}$ as a function of these quantities which we expect to be particularly useful for semi-analytical models of early galaxy formation. In addition, we find: (i) the measured redshift dependence of $M_{\rm crit}$ in the absence of radiation or streaming is $(1+z)^{-1.58}$, consistent with a constant virial temperature; (ii) increasing the UV background increases $M_{\rm crit}$ while steepening the redshift dependence, up to $(1+z)^{-5.7}$; (iii) baryon-dark matter streaming boosts $M_{\rm crit}$ but flattens the dependence on redshift; (iv) the combination of the two effects is not simply multiplicative.

description: A primary cause of failure of the highly active antiretroviral therapy (HAART) used to control the infection of human immunodeficiency virus type 1 (HIV-1) is the rapid emergence of strains that are resistant to one or more of the active agents used in typical multidrug regimens. Mutations of genes coding for inhibitor targets, such as protease, reverse transcriptase, and gp41, result in a reduced response to treatment from patients infected by resistant strains. The magnitude reached by the AIDS pandemic and the daunting problem of drug resistance elevate the need for new therapeutic agents with alternative mechanisms of action.   In the life cycle of HIV-1, the processes of genome recognition, dimerization, and packaging provide very attractive opportunities for the development of novel anti-retroviral strategies. These essential functions are mediated by the interactions between the nucleocapsid (NC) domain of the Gag polyprotein and a highly conserved region of genomic RNA, known as the packaging signal, or Psi-RNA. Located in the 5'-untranslated leader (5'-UTR), the ~120 nucleotides comprising Psi-RNA have been shown to fold into relatively stable secondary structures identified as stem-loop 1 through 4 (SL1-4), which serve as possible binding sites for NC during viral replication. The characteristics and structural determinants of these protein-RNA interactions have been extensively investigated to elucidate the role played by the different elements and enable the identification of viable targets.   Different strategies have been proposed to disrupt the mechanism of genome recognition, dimerization, and packaging by targeting key structures involved in these processes. We have employed an approach based on electrospray ionization (ESI) and Fourier transform ion cyclotron resonance mass spectrometry (FTICRMS) to investigate ligand-RNA interactions and evaluate the stability of NC-hairpin complexes in the presence of ligands. Furthermore, we have explored the possibility of employing tandem mass spectrometry to map the actual binding sites of small molecule ligands on individual stemloop domains of Psi-RNA. This approach was also extended to determine the effects of these ligands on the chaperone activity presented by NC.  Finally, we have taken advantage of the high mass limits and resolution of ESI-FTICRMS to study the binding interactions of a peptide library with the complete Psi-RNA. These biophysical studies have provided an ideal platform to screen possible therapeutics, as well as identifying new viral targets, which could lead to the development of antiretroviral agents that are capable of interfering with these key steps in the viral life cycle.

description: Reentrance, the return of a system from an ordered phase to a previously encountered less-ordered one as a controlled parameter is continuously varied, is a recurring theme found in disparate physical systems, from condensed matter to black holes. While diverse in its many incarnations and generally unsuspected, the cause of reentrance at the microscopic level is often not investigated thoroughly. Here, through detailed characterization and theoretical modeling, we uncover the microscopic mechanism behind reentrance in the strongly frustrated pyrochlore antiferromagnet Er$_2$Sn$_2$O$_7$. Taking advantage of the recent advance in rare earth stannate single crystal synthesis, we use heat capacity measurements to expose that Er$_2$Sn$_2$O$_7$ exhibits multiple instances of reentrance in its magnetic field $B$ vs. temperature $T$ phase diagram for magnetic fields along three cubic high symmetry directions. Through classical Monte Carlo simulations, mean field theory and classical linear spin-wave expansions, we argue that the origins of the multiple occurrences of reentrance observed in Er$_2$Sn$_2$O$_7$ are linked to soft modes. Depending on the field direction, these arise either from a direct $T=0$ competition between the field-evolved ground states, or from a field-induced enhancement of the competition with a distinct zero-field antiferromagnetic phase. In both scenarios, the phase competition enhances thermal fluctuations which entropically stabilize a specific ordered phase. This results in an increased transition temperature for certain field values and thus the reentrant behavior. Our work represents a detailed examination into the mechanisms responsible for reentrance in a frustrated magnet and may serve as a template for the interpretation of reentrant phenomena in other physical systems.

Based on this formulation, we proposed a new gauge-invariant definition of the magnetic monopole current which guarantees the magnetic charge quantization. We also demonstrated the magnetic monopole dominance in the string tension in SU(2) Yang-Mills theory on a lattice. Our formulation enables one to reproduce in the gauge-invariant way remarkable results obtained so far only in the Maximally Abelian gauge.

description: Following an explicit example, we present the chain of steps required for an event-by-event description of hadron production in high energy hadronic and nuclear collisions. We start from incoming nuclei, described in the Color Glass Condensate effective theory, whose collision creates the gluon fields of the glasma. Individual gluons are then sampled from the gluon fields' Husimi (smeared Wigner) distributions, and clustered using a new spacetime based algorithm. Clusters are fed into the Herwig event generator, which performs the hadronization, conserving energy and momentum. We discuss the physical implications of smearing and problems with the quasi particle picture for the studied processes. We compute spectra of charged hadrons and identified particles and their azimuthal momentum anisotropies, and address systematic uncertainties on observables, resulting from the general lack of detailed knowledge of the hadronization mechanism.

description: We study the distribution 1/sigma dsigma/dQt, where Qt is the modulus of the transverse momentum vector, obtained by summing over all hadrons, in the current hemisphere of the DIS Breit frame. We resum the large logarithms in the small Qt region, to next-to--leading logarithmic accuracy, including the non-global logarithms involved. We point out that this observable is simply related to the Drell-Yan vector boson and predicted Higgs Qt spectra at hadron colliders. Comparing our predictions to existing HERA data thus ought to be a valuable source of information on the role or absence of small-x (BFKL) effects, neglected in conventional resummations of such quantities.

The H alpha Galaxy Survey. III. Constraints on supernova progenitors from spatial correlations with H alpha emission

Subjects: subject: Astrophysics (astro-ph)

description: Aims: We attempt to constrain progenitors of the different types of supernovae from their spatial distributions relative to star formation regions in their host galaxies, as traced by H alpha + NII line emission. Methods: We analyse 63 supernovae which have occurred within galaxies from our H alpha survey of the local Universe. Three statistical tests are used, based on pixel statistics, H alpha radial growth curves, and total galaxy emission-line fluxes. Results: Many more type II supernovae come from regions of low or zero emission line flux than would be expected if the latter accurately traces high-mass star formation. We interpret this excess as a 40% `Runaway' fraction in the progenitor stars. Supernovae of types Ib and Ic do appear to trace star formation activity, with a much higher fraction coming from the centres of bright star formation regions than is the case for the type II supernovae. Type Ia supernovae overall show a weak correlation with locations of current star formation, but there is evidence that a significant minority, up to about 40%, may be linked to the young stellar population. The radial distribution of all core-collapse supernovae (types Ib, Ic and II) closely follows that of the line emission and hence star formation in the their host galaxies, apart from a central deficiency which is less marked for supernovae of types Ib and Ic than for those of type II. Core-collapse supernova rates overall are consistent with being proportional to galaxy total luminosities and star formation rates; however, within this total the type Ib and Ic supernovae show a moderate bias towards more luminous host galaxies, and type II supernovae a slight bias towards lower-luminosity hosts.

description: The application of developmentally appropriate pain assessment and pain management techniques in the prehospital emergency setting continues to fall behind other areas of health care. To date only limited research has been conducted to improve these techniques in the prehospital setting. The goals of the current study were two-fold:  1) To assess paramedic knowledge regarding pediatric pain management, and 2) To pilot test an educational intervention designed to a) teach paramedics about pediatric pain physiology, developmental aspects of pediatric pain, and pediatric pain assessment and management strategies, and b) teach paramedics how to use developmentally appropriate self-report and observational pain scales with children of different ages. Paramedics from two counties in Delaware participated in the study. Baseline measures of pain management practices, knowledge about pain management, and comfort and confidence in treating pediatric patients were collected during mandatory continuing education sessions; similar post-study measures were collected 15 months after baseline.  Paramedics in the experimental group received the educational intervention while paramedics in the control did not receive the intervention. Paramedics from each group were asked to complete an electronic report after each pediatric ambulance incident specifying any pain assessment or interventions they conducted.  Results revealed that paramedics who participated in the educational intervention were over two times more likely to assess pediatric pain compared to the control group.  The educational intervention also led to an increased frequency of pain treatment among experimental group paramedics. There were no group differences in paramedic comfort or confidence at both pre- and post-study measurements.  Pediatric pain knowledge significantly decreased from baseline to post-study measurement in the control group while experimental group knowledge increased slightly over time.  Prehospital pediatric pain assessment and management is an important and understudied aspect of pediatric medical care. This study is an important first step in the investigation of strategies to improve prehospital pediatric pain management. The results of this study indicate that an educational intervention, including appropriate assessment tools, is an effective means to improving paramedic patient care skills related to pain assessment and management. Study findings have important implications for paramedic training and continuing education.

description: This work quantifies the impacts of urban development on groundwater storage and groundwater-surface water interactions using intensive data analysis and mathematical modeling.  The monthly water balance for the period 2000-2009 for 65 Baltimore area watersheds was calculated using remote sensing data and the dense network of instrumented sites in this region. This analysis included estimation of spatially-distributed anthropogenic fluxes (water supply pipe leakage, lawn irrigation, and infiltration and inflow (I&I) of groundwater and stormwater into wastewater pipes) as well as natural fluxes of precipitation, streamflow, and evapotranspiration.  Inflow fluxes of water supply pipe leakage and lawn irrigation were significant but small compared to precipitation, but I&I was approximately equal to gaged streamflow.  Building on knowledge of the altered water balance, an integrated hydrologic model of the Baltimore metropolitan region was developed to quantify the impact of urban development on groundwater storage.  The three-dimensional groundwater-surface water-land surface model ParFlow.CLM was implemented and a methodology to incorporate urban and hydrogeologic input datasets was developed.  Using the model, the impacts of reduced vegetative cover, impervious surfaces, I&I, and other anthropogenic discharge and recharge fluxes were isolated.  Removal of I&I led to the largest change in storage, and removal of impervious surface cover had the smallest effect.  To investigate the relationship between pre-event water proportion, storage, and streamflow at small watershed scales spanning a gradient of urbanization, chemical hydrograph separation, hillslope numerical experiments, and simple dynamical systems analysis were utilized.  From analysis of high-frequency specific conductance data, the pre-event water proportion of stormflow was found to be greatest for storms with higher total precipitation.  Using the simple dynamical systems approach, watersheds with larger percentages of impervious surfaces were found to have the largest sensitivity of streamflow to changes in storage.  HydroGeoSphere, a three-dimensional groundwater-surface water flow and transport model, was implemented in an idealized hillslope and showed that the relationship between streamflow and storage was clockwise hysteretic.  Overall this work demonstrates the importance of infrastructure leakage on urban hydrologic systems and shows that pre-event water contributions of stormflow are primarily related to precipitation and not initial storage in urban watersheds.

description: In this paper, we analyze time series measurements of PSR B0943+10 and fit them with a non-radial oscillation model. The model we apply was first developed for total intensity measurements in an earlier paper, and expanded to encompass linear polarization in a companion paper to this one. We use PSR B0943+10 for the initial tests of our model because it has a simple geometry, it has been exhaustively studied in the literature, and its behavior is well-documented. As prelude to quantitative fitting, we have reanalyzed previously published archival data of PSR B0943+10 and uncovered subtle but significant behavior that is difficult to explain in the framework of the drifting spark model. Our fits of a non-radial oscillation model are able to successfully reproduce the observed behavior in this pulsar.

description: Trade-offs between feasible absorption and scattering cross sections of obstacles confined to an arbitrarily shaped volume are formulated as a multi-objective optimization problem solvable by Lagrangian-dual methods. Solutions to this optimization problem yield a Pareto-optimal set, the shape of which reveals the feasibility of achieving simultaneously extremal absorption and scattering. Two forms of the trade-off problems are considered involving both loss and reactive material parameters. Numerical comparisons between the derived multi-objective bounds and several classes of realized structures are made. Additionally, low-frequency (electrically small, long wavelength) limits are examined for certain special cases.

description: In this paper, we study the drying of water-saturated porous polydimethylsiloxane (PDMS) elastomers with closed porosity in which the evaporation of water is possible only via the diffusion across the PDMS. Starting from water/PDMS emulsions, we fabricate soft macroporous samples with different pore diameter distributions and average diameters ranging from 10 to 300 $μ$m. In these materials, the drying may lead either to a collapsed state with low porosity or to the cavitation and reopening of a fraction of the pores. Using optical microscopy and porosity measurements, we showed the importance of the pore diameters and interactions on the result of drying. At pore diameters lower than 30 $μ$m, the majority of pores remain collapsed. We attribute the permanence of the collapse of most small pores to a low probability of cavitation and to the adhesion of the pore walls. Pores with diameters larger than 100 $μ$m tend to reopen after the water they contain cavitates. The behavior of pores with diameters ranging from 30 to 100 $μ$m depends on the porosity and drying temperature. We also visualize collective cavitation upon drying of sponges initially saturated with a sodium chloride solution. In this case, the cavitation in the largest pores leads to reopening of small pores in a neighboring zone of the sample. To our knowledge, our results present the first experimental proof of the pore-size-dependent and cooperative nature of the response of soft sponges with closed porosity to drying.
PATHWAYS FROM FAMILY CHAOS TO CHILDREN'S DISRUPTIVE BEAHVIOR: EXAMINING THE MEDIATING ROLES OF MATERNAL HARSH DISCIPLINE PRACTICES AND CHILDREN'S SOCIAL INFORMATION PROCESSING

description: The current study attempted to test a meditational model suggesting that maternal harsh discipline practices and children's social information processing mediate the relation between family chaos and children's disruptive behavior. Participants included 97 preschool children and their caregivers. Parents completed two questionnaires and children participated in assessments to measure social information processing. Results of the current study suggest that children from chaotic home environments are more likely to experience maternal harsh discipline practices. However, results did not support the overall meditational model. None of the variables significantly predicted child behavior problems. It is likely that measurement issues, including poor reliability of measures as well as a single method of assessment for many of the variables, contributed to the insignificant findings.

description: Pathological laughing and crying (PLC), which includes laughing and/or crying that is either of abnormal intensity, prolonged duration, or difficult to control, has been described as causing embarrassment and hindering communication with others. The current project explored PLC in individuals with multiple sclerosis (MS), a debilitating disorder of the central nervous system that commonly begins in young adulthood. Although normal laughter and crying are poor barometers of mood, both are integral to communication. Accordingly, it was hypothesized that PLC is not simply a reflection of underlying mood, and that it is associated with loneliness and communication problems. Seventy eight participants with self-identified MS completed internet surveys in conjunction with an informant, and an additional 29 individuals with MS completed the survey without an informant. All participants provided demographic information and independently rated the individual with MS based on overall medical complaints, general physical functioning, cognitive functioning, mood, communication, and PLC. A Principle components analysis indicated that self-reported PLC symptoms and mood symptoms were best represented as distinct factors. Three hierarchical regression models were used to test the effect of PLC on communication, and three logistic models tested the effects of PLC on whether loneliness was identified as a primary concern from among a list of medical complaints. All analyses statistically controlled for physical functioning, mood, and cognition. Both types of regression were conducted three times, once using the patient's responses, once using the informant's responses, and once using a combination of their responses. All regression analyses indicated that PLC is a significant contributor to loneliness and impaired communication. It is concluded that PLC poses a significant risk for loneliness and impairment in communication. Physicians attending to PLC may improve the quality of their patients' lives through patient education and treatment.
The Actualization Threshold Model: A Unified Framework Resolving Quantum Anomalies, Galactic Rotation, and Cosmic Expansion Without Dark Matter or Dark Energy
Creators: name: Mc Kelllar, Emil Arthur
Publisher: name: Zenodo
Year: 2025

description: This unified theoretical paper introduces the Actualization Threshold Model (AF), a deterministic framework for the emergence of particles, fields, and spacetime from Planck-scale energy fluctuations. AF integrates relativistic energy, quantum uncertainty, directional suppression by the cosmic gravitational wave background (CGWB), and local curvature to define when quantum fluctuations become real.

The model is validated against twelve known anomalies, including meson decays, neutrino emissions, muon drift, Josephson junctions, planetary drift, smooth galaxy formation, CMB interference patterns, and cosmic expansion. AF replaces the need for both dark matter and dark energy by providing a single, testable function rooted in physical thresholds.

All predictions are compared against peer-reviewed data. No tuning or exotic matter is used. The model's predictive power spans subatomic to cosmological scales and introduces a physically motivated explanation for the structure and behavior of the universe.

description: Properties of type III and type IIIb bursts in the frequency band of 8-80 MHz observed by the radio telescopes Ukrainian Radio Interferometer of NASU-2 (URAN-2) (Poltava) and Giant Ukrainian Radio Telescope (GURT) (Kharkiv) during the Parker Solar Probe (PSP) perihelion in April 2019 are discussed. These correspond of those that were observed by PSP at frequencies <19 MHz. We analyze dependences of drift rates and durations on frequency for these bursts. We show that drift rate dependences on frequency agree well with those derived from the Newkirk corona if source velocities are between 0.17 and 0.2 c for both type IIIb bursts and type III bursts under the assumption that the first ones are fundamentals and the second ones are their harmonics. However, all observational dependences are flatter in comparison with the dependences for a Newkirk corona. We assume that this can be related with coronal temperature decreasing at heliocentric distances from 1.35 to 6.5 solar radii. Duration dependencies of type IIIb and type III bursts on frequency in the range of 10-70 MHz are also obtained. We note that the durations and drift rates of type III bursts as well as their dependences on frequency differ essentially from those for type IIIb bursts.

Plasma Turbulence in the Local Bubble

description: Turbulence in the Local Bubble could play an important role in the thermodynamics of the gas that is there. The best astronomical technique for measuring turbulence in astrophysical plasmas is radio scintillation. Measurements of the level of scattering to the nearby pulsar B0950+08 by Philips and Clegg in 1992 showed a markedly lower value for the line-of-sight averaged turbulent intensity parameter $$ than is observed for other pulsars, consistent with radio wave propagation through a highly rarefied plasma. In this paper, we discuss the observational progress that has been made since that time. At present, there are four pulsars (B0950+08, B1133+16, J0437-4715, and B0809+74) whose lines of sight seem to lie mainly within the local bubble. The mean densities and line of sight components of the interstellar magnetic field along these lines of sight are smaller than nominal values for pulsars, but not by as much expected. Three of the four pulsars also have measurements of interstellar scintillation. The value of the parameter $$ is smaller than normal for two of them, but is completely nominal for the third. This inconclusive status of affairs could be improved by measurements and analysis of ``arcs'' in ``secondary spectra'' of pulsars.

description: Comet-centaur 29P/Schwassmann-Wachmann 1 was observed in CO+ emission and contin-uum during 2007-2009 using the 6-m Big Telescope Alt-azimuth at the Special Astrophysical Observatory of the Russian Academy of Sciences. We analysed the morphology of the CO+ and dust coma. The distributions of dust and CO+ ions in the coma are not similar and vary depending on the level of comet activity. CO+ ions are more concentrated towards the nucleus than the dust continuum. The column density of the CO+ was derived and found to vary from 3.7*10^9 to 4.3*10^10 ions cm^-2. The production rate of CO+ was estimated to be from (7.01)*10^24 to (1.15)*10^26 ions s^-1. We discuss possible mechanisms for the ionization of cometary material and show that impact ionization by solar wind particles is probably the main ionization mechanism at large heliocentric distances.

description: We consider the azimuthal and $P_T$ dependence of hadrons produced in unpolarized Semi-Inclusive Deep Inelastic Scattering (SIDIS) processes, within the factorized QCD parton model. It is shown that at small $P_T$ values, $P_T \lsim 1$ GeV/c, lowest order contributions, coupled to unintegrated (Transverse Momentum Dependent) quark distribution and fragmentation functions, describe all data. At larger $P_T$ values, $P_T \gsim 1$ GeV/c, the usual pQCD higher order collinear contributions dominate. Having explained the full $P_T$ range of available data, we give new detailed predictions concerning the azimuthal and $P_T$ dependence of hadrons which could be measured in ongoing or planned experiments by HERMES, COMPASS and JLab collaborations.

description: Genus Asterolepis Eichwald, 1840 sensu Agassiz (1844)
 TYPE SPECIES. — Asterolepis ornata Eichwald, 1840 (Eichwald 1840b), sensu Agassiz (1844); East Baltic area, Main Devonian Field, Gauja Formation, Middle Devonian (late Givetian).
REMARKS
 Eichwald first proposed the name Asterolepis ornata in a November, 1839, letter to H. G. Bronn of Stuttgart. The letter was published sometime after April of the following year (Eichwald 1840b) in the annual journal at which Bronn served as co-editor, Neues Jahrbuch für Mineralogie, Geognosie, Geologie und Petrekaften-Kunde. This reference has been mis- cited (e.g., Lyarskaja 1981; Upeniece 2011) as a publication of Neues Jahrbuch für Mineralogie, Geognosie, Geologie und Paläontologie, a title change for the journal that only occurred after Bronn’s death in 1862 and then continued through to 1942. In an earlier 1840 publication (published in April), Eichwald (1840a: 79) mentions, though misspells, “Astrolepis” but makes no formal proposal of the name and does not use the name of the type species, A. ornata. His casual use of the name “Astrolepis” here is likely due to his previously written, though not yet published, proposal of A. ornata in his letter to Bronn. The quirk of publication schedules means that the earlier Eichwald (1840a) publication, in Bulletin scientifique de l’Académie impériale des Sciences de Saint Petersbourg, is the first published occurrence of “Astrolepis,” though not of the type species name. This understanding reveals that the original spelling of Asterolepis is actually “Astrolepis.” However, considering the subsequent spelling’s prevailing (though not exclusive; see Murphy et al. 1976) usage and its common attribution to the publication containing the original spelling (e.g., Traquair 1888; Woodward 1891; Rohon 1899; Gross 1931, 1933; Karatajūte-Talimaa 1963; Lyarskaja 1981; Janvier & Villarroel 2000; Moloshnikov 2008; Newman & Den Blaauwen 2018), the International Code of Zoological Nomenclature (Article 33.3.1) supports Asterolepis as a correct spelling.

Investigation of entanglement measures across the magnetization process of a highly frustrated spin-1/2 Heisenberg octahedral chain as a new paradigm of the localized-magnon approach

description: The bipartite entanglement across the magnetization process of a highly frustrated spin-1/2 Heisenberg octahedral chain is examined within the concept of localized magnons, which enables a simple calculation of the concurrence measuring a strength of the pairwise entanglement between nearest-neighbor and next-nearest-neighbor spins from square plaquettes. A full exact diagonalization of the finite-size Heisenberg octahedral chain with up to 4 unit cells (20 spins) evidences an extraordinary high precision of the localized-magnon theory in predicting measures of the bipartite entanglement at sufficiently low temperatures. While the monomer-tetramer phase emergent at low enough magnetic fields exhibits presence (absence) of the bipartite entanglement between the nearest-neighbor (next-nearest-neighbor) spins, the magnon-crystal phase emergent below the saturation field contrarily displays identical bipartite entanglement between the nearest-neighbor and next-nearest-neighbor spins. The presented results verify a new paradigm of the localized-magnon approach concerned with a simple calculation of entanglement measures.

Quasi-universal relations for generalized Skyrme stars

description: First proposed in 2013 by Yagi and Yunes, the quasi-universal \emph{I-Love-Q relations} consist of a set of relations between the moment of inertia, the spin-induced quadrupole moment and the electric quadrupolar tidal deformability of neutron stars which are independent of the Equation of State (EoS) within an accuracy of $\sim1\%$. In this work, we show that these relations hold for different Skyrme-based nuclear matter EoS and also for the star-like solutions of different Einstein-BPS-Skyrme-models, some of which do not even present a barotropic equation of state. Further, other quasi-universal relations are analyzed, and together with recent GW observations, we use them to select the generalized Skyrme model that better reproduces observations. Our results reaffirm both the universality of the \emph{I-Love-Q} relations and the suitability of generalized Skyrme models to describe nuclear matter inside neutron stars.
