description: Several extensions of the Standard Model predict the existence of new neutral spin-1 resonances associated to the electroweak symmetry breaking sector. Using the data from ATLAS (with integrated luminosity of L=1.02 fb^{-1}) and CMS (with integrated luminosity of L=1.55 fb^{-1}) on the production of W+W- pairs through the process pp -> l^+ l^{\prime -} \sla{E}_T, we place model independent bounds on these new vector resonances masses, couplings and widths. Our analyses show that the present data excludes new neutral vector resonances with masses up to 1-2.3 TeV depending on their couplings and widths. We also demonstrate how to extend our analysis framework to different models working a specific example.

description: We present colour transformations for the conversion of the Wide-Field Survey Explorer (WISE) W1, W2, and W3 magnitudes to the Johnson-Cousins (BVIc), Sloan Digital Sky Survey (gri), and Two Micron All Sky Survey JHKs photometric systems, for red clump (RC) stars. RC stars were selected from the Third Radial Velocity Experiment (RAVE) Data Release (DR3). The apparent magnitudes were collected by matching the coordinates of this sample with different photometric catalogues. The final sample (355 RC stars) used to obtain metallicity dependent-and free of metallicity- transformations between WISE and Johnson-Cousins, SDSS, 2MASS photometric systems. These transformations combined with known absolute magnitudes at shorter wavelengths can be used in space density determinations for the Galactic (thin and thick) discs at distances larger than the ones evaluated with JHKs photometry alone, hence providing a powerful tool in the analysis of Galactic structure.

description: We study the time-dependent backscattered current produced in a quantum wire when a local barrier is suddenly switched on. Previous investigations are improved by taking into account the finite length of the device. We establish two different regimes in terms of the relationship between the energy scales associated to the voltage and the length of the system. We show how previous results, valid for wires of infinite length, are modified by the finite size of the system. In particular our study reveals a rich pattern of temporal steps within which the current suffers an initial relaxation followed by temporary revivals. By employing both analytical and numerical methods we describe peculiar features of this structure. From this analysis one concludes that our results render a recently proposed approach to the determination of the Luttinger parameter K, more realistic.

description: Introducing a perturbative definition, phase space path integrals can be calculated without slicing. This leads to a short-time expansion of the quantum-mechanical path amplitude, or a high-temperature expansion of the unnormalized density matrix, respectively. We use the proposed formalism to calculate the effective classical Hamiltonian for the harmonic oscillator.

description: The distillability of bipartite entangled state as seen by moving observers has been investigated. It is found that the same initial entanglement for a state parameter $α$ and its "normalized partner" $\sqrt{1-α^2}$ will be degraded as seen by moving observer. It is shown that in the ultra relativistic limit, the state does not have distillable entanglement for any $α$.

description: We report both 23Na and 75As NMR studies on hole-doped Ca1-xNaxFe2As2 superconducting single crystals (x\approx 0.67) with Tc =32 K. Singlet superconductivity is suggested by a sharp drop of the Knight shift 75K below Tc. The spin-lattice relaxation rate 1/T1 does not show the Slichter-Hebel coherence peak, which suggests an unconventional pairing. The penetration depth is estimated to be 0.24 μm at T=2 K. 1/75T1T shows an anisotropic behavior and a prominent low-temperature upturn, which indicates strong low-energy antiferromagnetic spin fluctuations and supports a magnetic origin of superconductivity.

We observe microwave precession in junctions with different thickness of the free magnetization layer. Taking advantage of the ferromagnetic interlayer exchange coupling between the free and reference layer in the MTJ and perpendicular interface anisotropy in thin CoFeB electrode we demonstrate the nanometer scale device that can generate high frequency signal without external magnetic field applied. The amplitude of the oscillation exceeds 10 nV/Hz^0.5 at 1.5 GHz.

description: Recently, X. Qi and J. Hou [Phys. Rev. A 85, 022334 (2012)] provided optimal entanglement witnesses without the spanning property. These witnesses are associated to indecomposable positive linear maps, but it is not checked whether partial transposes of these witnesses are also optimal. We show that partial transposes of these entanglement witnesses have spanning property, and these witnesses are indeed optimal PPTES witnesses (non-decomposable optimal entanglement witnesses).

description: Global, general relativistic magnetohydrodynamic (GRMHD) simulations of nonradiative, magnetized disks are widely used to model accreting black holes. We have performed a convergence study of GRMHD models computed with HARM3D. The models span a factor of 4 in linear resolution, from 96x96x64 to 384x384x256. We consider three diagnostics of convergence: (1) dimensionless shell-averaged quantities such as plasma β; (2) the azimuthal correlation length of fluid variables; and (3) synthetic spectra of the source including synchrotron emission, absorption, and Compton scattering. Shell-averaged temperature is, except for the lowest resolution run, nearly independent of resolution; shell-averaged plasma β decreases steadily with resolution but shows signs of convergence. The azimuthal correlation lengths of density, internal energy, and temperature decrease steadily with resolution but show signs of convergence. In contrast, the azimuthal correlation length of magnetic field decreases nearly linearly with grid size. We argue by analogy with local models, however, that convergence should be achieved with another factor of 2 in resolution. Synthetic spectra are, except for the lowest resolution run, nearly independent of resolution. The convergence behavior is consistent with that of higher physical resolution local model (shearing box) calculations and with the recent nonrelativistic global convergence studies of Hawley et al. (2011).

Identification of a Fundamental Transition in a Turbulently-Supported Interstellar Medium

description: The interstellar medium in star-forming galaxies is a multiphase gas in which turbulent support is at least as important as thermal pressure. Sustaining this configuration requires continuous radiative cooling, such that the overall average cooling rate matches the decay rate of turbulent energy into the medium. Here we carry out a set of numerical simulations of a stratified, turbulently stirred, radiatively cooled medium, which uncover a fundamental transition at a critical one-dimensional turbulent velocity of ~ 35 km/s. At turbulent velocities below ~35 km/s, corresponding to temperatures below 300,000 K, the medium is stable, as the time for gas to cool is roughly constant as a function of temperature. On the other hand, at turbulent velocities above the critical value, the gas is shocked into an unstable regime in which the cooling time increases strongly with temperature, meaning that a substantial fraction of the interstellar medium is unable to cool on a turbulent dissipation timescale. This naturally leads to runaway heating and ejection of gas from any stratified medium with a one-dimensional turbulent velocity above ~35 km/s, a result that has implications for galaxy evolution at all redshifts.

Initial spin periods of neutron stars in supernova remnants

description: We present estimates of initial spin periods, $P_0$, for radio pulsars associated with supernova remnants. By using the published data on 30 objects, we were able to derive a reliable estimate for the initial spin period, assuming standard magneto-dipole spin-down (braking index n=3), in many cases. Our set of estimates is still not sufficient to infer the exact shape of the initial period distribution. However, we show that a gaussian distribution with mean and deviation $\sim 0.1$ s is consistent with our results, while flat, wide distributions and very narrow ones are disfavored.

Symplectic integrators with adaptive time steps

description: In recent decades, there have been many attempts to construct symplectic integrators with variable time steps, with rather disappointing results. In this paper we identify the causes for this lack of performance, and find that they fall into two categories. In the first, the time step is considered a function of time alone, Δ=Δ(t). In this case, backwards error analysis shows that while the algorithms remain symplectic, parametric instabilities arise because of resonance between oscillations of Δ(t) and the orbital motion. In the second category the time step is a function of phase space variables Δ=Δ(q,p). In this case, the system of equations to be solved is analyzed by introducing a new time variable τwith dt=Δ(q,p) dτ. The transformed equations are no longer in Hamiltonian form, and thus are not guaranteed to be stable even when integrated using a method which is symplectic for constant Δ. We analyze two methods for integrating the transformed equations which do, however, preserve the structure of the original equations. The first is an extended phase space method, which has been successfully used in previous studies of adaptive time step symplectic integrators. The second, novel, method is based on a non-canonical mixed-variable generating function. Numerical trials for both of these methods show good results, without parametric instabilities or spurious growth or damping. It is then shown how to adapt the time step to an error estimate found by backward error analysis, in order to optimize the time-stepping scheme. Numerical results are obtained using this formulation and compared with other time-stepping schemes for the extended phase space symplectic method.

Assessing Undergraduate Instructors' Knowledge and Attitudes Towards Preprints

Publisher: name: Zenodo
Year: 2023

description: Preprints, or preliminary versions of scientific papers posted online before formal peer review, have become an important component of scholarly communication workflow in many disciplines. Preprints hold potential for stimulating critical thinking in students. The objective of this research project was to assess undergraduate instructors' knowledge and attitudes surrounding preprints in order to determine how receptive they would be to incorporating this resource into their teaching. To this end, we designed a survey to gather data on instructors' familiarity with preprints, their comfort level in integrating them into teaching, and their desire to utilize preprints in the classroom. The survey was distributed to 123 instructors at the University of Richmond (U of R), 46 of whom completed it. Participants were asked to respond to Likert-scale questions and provide insight into their experiences with using published journal articles, preprints, and peer review in their teaching. We observed that all instructors were comfortable with teaching students about how the peer review process works and the majority were comfortable with incorporating published journal articles into their teaching. Nevertheless, we found that instructors were much less comfortable with incorporating preprints into their teaching and most answered that they had never before used preprints in the classroom. When asked what would motivate them to integrate preprints into their teaching, instructors responded that they were most motivated by strengthening students' critical thinking skills. The majority saw "difficulty finding relevant preprints" to be the largest barrier to using preprints in the classroom. Though instructors were largely unfamiliar with using preprints in educational settings, those most receptive to using them indicated that they would like to receive more resources to help them incorporate preprints into their teaching. Providing instructors with access to curated resources, lesson plans, and rubrics could help address barriers to using preprints in the classroom and create an environment conducive to embracing preprints as valuable teaching tools.

description: In much of the Western world pitches are conceived of as existing in a metaphorical 2-dimensional space along a vertical axis where “high frequency” pitches lie higher and “low frequency” pitches are lower. but this isn’t a universal phenomenon. In some cultures, and even for some children in the Western world, this orientation is reversed. In many parts of the world, pitches exist in other metaphorical spaces (e.g. thick/thin; big/small); metaphorical spaces related to mass (e.g. heavy/light); metaphorical kinship relations (e.g. grandmother/daughter), age metaphors (e.g. old voices/young voices); or very culturally specific senses (e.g. crocodile/those who follow crocodile).This is a non-exhaustive list of many of these pitch metaphors with relevant references to help those who are curious get a sense of the global diversity of pitch metaphors throughout time.

title: Molecular immune responses of lumpfish (Cyclopterus lumpus) to aeromonas salmonicida
Creators: name: Chakraborty, Setu
Publisher: name: Memorial University of Newfoundland

description: Lumpfish (Cyclopterus lumpus) have been utilized to biocontrol sea-lice (e.g., Lepeophtheirus salmonis) infestations in Atlantic salmon (Salmo salar) farms in the North Atlantic region. Aeromonas salmonicida subsp. salmonicida is a Gram-negative facultative intracellular pathogen infecting several fish species, including lumpfish. Here, I established an A. salmonicida systemic infection model in lumpfish. Juvenile lumpfish were intraperitoneally (ip) injected with different doses of A. salmonicida strain J223. A. salmonicida median lethal dose (LD50) was calculated at 102 colony-forming units (CFU)/dose. Samples from blood, head kidney, spleen, and liver were collected at different time points to determine the infection kinetics. Triplicated RNA samples from the head kidney, spleen, and liver of non-infected and infected (104 CFU/dose) lumpfish at 3 and 10 days post-infection (dpi) were utilized for RNA sequencing (RNA-Seq). Analysis of RNA-Seq data suggested that A. salmonicida could induce lethal infection in lumpfish by septic-like shock, suppression of the adaptive immune system, impairment of the DNA repair system, and disruption of cytoskeleton structure. Thus, an effective vaccine for lumpfish against A. salmonicida is highly needed. Here, I evaluated the immune protective effect of A. salmonicida bacterins and outer membrane proteins (OMPs) expressing iron-regulated outer membrane proteins (IROMPs) in lumpfish. However, my results demonstrate that vaccines do not confer protection to lumpfish against A. salmonicida J223. Additionally, I observed that formalin-killed A. salmonicida J223 bacterins do not increase IgM titers in lumpfish serum. Instead, the bacterins downregulate genes encoding IgM, MHC-II, and CD4, which indicates immune suppression and vaccine’s inability to trigger humoral and cell-mediated immune responses. Furthermore, different post-transcriptional factors (e.g., microRNAs (miRNAs)) that significantly determine an organism’s disease state are not explored yet in lumpfish. Therefore, I characterized miRNA encoding genes in lumpfish from three developmental stages (adult, embryos, and larvae) in this study, providing the reference miRNAome for future functional studies. Altogether, 443 unique mature miRNAs were identified in lumpfish. Transcriptomics analysis suggested organ-specific and age-specific expression of miRNAs. This thesis contributes significantly to understanding lumpfish- A. salmonicida interactions and provides guidelines for future host-pathogen interaction and vaccine studies.
Graphene on incommensurate substrates: trigonal warping and emerging Dirac cone replicas with halved group velocity

description: The adhesion of graphene on slightly lattice-mismatched surfaces, for instance of hexagonal boron nitride (hBN) or Ir(111), gives rise to a complex landscape of sublattice symmetry-breaking potentials for the Dirac fermions. Whereas a gap at the Dirac point opens for perfectly lattice-matched graphene on hBN, we show that the small lattice incommensurability prevents the opening of this gap and rather leads to a renormalized Dirac dispersion with a trigonal warping. This warping breaks the effective time reversal symmetry in a single valley. On top of this a new set of massless Dirac fermions is generated, which are characterized by a group velocity that is half the one of pristine graphene.
Quenched Cold Accretion of a Large Scale Metal-Poor Filament due to Virial Shocking in the Halo of a Massive z=0.7 Galaxy

description: Using HST/COS/STIS and HIRES/Keck high-resolution spectra, we have studied a remarkable HI absorbing complex at z=0.672 toward the quasar Q1317+277. The HI absorption has a velocity spread of 1600 km/s, comprises 21 Voigt profile components, and resides at an impact parameter of D=58 kpc from a bright, high mass [log(M_vir/M_sun) ~ 13.7] elliptical galaxy that is deduced to have a 6 Gyr old, solar metallicity stellar population. Ionization models suggest the majority of the structure is cold gas surrounding a shock heated cloud that is kinematically adjacent to a multi-phase group of clouds with detected CIII, CIV and OVI absorption, suggestive of a conductive interface near the shock. The deduced metallicities are consistent with the moderate in situ enrichment relative to the levels observed in the z ~ 3 Ly-alpha forest. We interpret the HI complex as a metal-poor filamentary structure being shock heated as it accretes into the halo of the galaxy. The data support the scenario of an early formation period (z > 4) in which the galaxy was presumably fed by cold-mode gas accretion that was later quenched via virial shocking by the hot halo such that, by intermediate redshift, the cold filamentary accreting gas is continuing to be disrupted by shock heating. Thus, continued filamentary accretion is being mixed into the hot halo, indicating that the star formation of the galaxy will likely remain quenched. To date, the galaxy and the HI absorption complex provide some of the most compelling observational data supporting the theoretical picture in which accretion is virial shocked in the hot coronal halos of high mass galaxies.

description: We review a resistor network approach to the numerical solution of the inverse problem of electrical impedance tomography (EIT). The networks arise in the context of finite volume discretizations of the elliptic equation for the electric potential, on sparse and adaptively refined grids that we call optimal. The name refers to the fact that the grids give spectrally accurate approximations of the Dirichlet to Neumann map, the data in EIT. The fundamental feature of the optimal grids in inversion is that they connect the discrete inverse problem for resistor networks to the continuum EIT problem.

description: We present a first-principles harmonic unification of General Relativity and Quantum Field Theory through the formalism of Sixta+ Theory, replacing the spacetime manifold of Einstein with a dynamically twisting, observer-centered dimensional harmonic structure. In this framework, curvature arises as a projection of twist-phase resonance, and mass-energy is redefined as a harmonic knot of dimensional tension. Quantum fields are no longer treated as external additions to spacetime but emerge from recursive eigenmodes of the Universal Twist Laplacian. We derive the gravitational field equations, quantum coupling constants, and curvature tensors as emergent harmonics within a non-commutative dimensional algebra, unifying both paradigms through a single spectral density function.

description: The exponential growth of data in big data warehouses Presents Significant challenges to data quality, consistency, and integrity. Conventional data validation and quality assurance practices do not scale well, leading to inconsistencies, errors, and inefficiencies. This article presents an AI-based data profiling and quality assurance system that uses machine learning and anomaly detection methods to validate data, perform consistency checks, and minimize errors. The system improves data integrity and reliability by using predictive analytics, rule-based learning, and real-time monitoring to identify and correct differences in an efficient manner. By leveraging AI-driven insights, organizations can automate data governance, lower the cost of operations, and enhance decision-making processes. The process is especially helpful for those sectors that are dependent on high-quality data, like healthcare, finance, and enterprise data management. This research emphasizes the business significance of AI-based data quality assurance, which is demonstrated to possess a revolutionary capability in large-scale data warehousing systems.

Using 132, 20-minute observations, several instances of MSTIDs were detected, all having wavefronts aligned northwest to southeast and mostly propagating toward the southwest, consistent with previous studies of MSTIDs. However, some were also found to move toward the northeast. It was found that both classes of MSTIDs were only found when sporadic-E (Es) layers of moderate peak density (1.53 MHz that was not present when 1.5

description: When ultrafast noncritical cascaded second-harmonic generation of energetic femtosecond pulses occur in a bulk lithium niobate crystal optical Cherenkov waves are formed in the near- to mid-IR. Numerical simulations show that the few-cycle solitons radiate Cherenkov (dispersive) waves in the $λ=2.2-4.5\mic$ range when pumping at $λ_1=1.2-1.8\mic$. The exact phase-matching point depends on the soliton wavelength, and we show that a simple longpass filter can separate the Cherenkov waves from the solitons. The Cherenkov waves are born few-cycle with an excellent Gaussian pulse shape, and the conversion efficiency is up to 25%. Thus, optical Cherenkov waves formed with cascaded nonlinearities could become an efficient source of energetic near- to mid-IR few-cycle pulses.

description: The Internet of Things and Services is a rapidly growing concept that illustrates that the ever increasing amount of physical items of our daily life which become addressable through a network could be made more easily manageable and usable through the use of Services. This surge of exposed resources along with the level of privacy and value of the information they hold, together with the increase of their usage make for an augmentation in the number of the security threats and violation attempts that existing security systems do not appear robust enough to address. In this paper, the authors underline this increase in risk and identify the requirements for resources to be more resilient in this type of environment while keeping an important level of flexibility. In addition, the authors propose an architectural model of Self Managed Security Cell, which leverages on current knowledge in large scale security systems, information management and autonomous systems.
