description: We present a detailed synchrotron x-ray scattering study of the charge-density-wave (CDW) order in simple tetragonal HgBa$_2$CuO$_{4+δ}$ (Hg1201). Resonant soft x-ray scattering measurements reveal that short-range order appears at a temperature that is distinctly lower than the pseudogap temperature and in excellent agreement with a prior transient reflectivity result. Despite considerable structural differences between Hg1201 and YBa$_2$Cu$_3$O$_{6+δ}$, the CDW correlations exhibit similar doping dependencies, and we demonstrate a universal relationship between the CDW wave vector and the size of the reconstructed Fermi pocket observed in quantum oscillation experiments. The CDW correlations in Hg1201 vanish already below optimal doping, once the correlation length is comparable to the CDW modulation period, and they appear to be limited by the disorder potential from unit cells hosting two interstitial oxygen atoms. A complementary hard x-ray diffraction measurement, performed on an underdoped Hg1201 sample in magnetic fields along the crystallographic $c$ axis of up to 16 T, provides information about the form factor of the CDW order. As expected from the single-CuO$_2$-layer structure of Hg1201, the CDW correlations vanish at half-integer values of $L$ and appear to be peaked at integer $L$. We conclude that the atomic displacements associated with the short-range CDW order are mainly planar, within the CuO$_2$ layers.

Morphological description.
The fur color is dark brown to cinnamon, grayish dorsally, and pale brown ventrally, showing slight contrast between both sides (Fig. 7). The ears are wider than long and joined at the forehead. Antitragus is well developed, with a broad base. The tragus is small, wide, and square in shape. Snout elongated, with smooth upper lips. Gular-thoracic gland present in males.
Skull elongated, with variations in the posterior portion of the braincase; in some specimens, the posterior region is more elevated, while in others, it is flatter (Fig. 7). Similarly, the sagittal crest in some specimens is notably well-developed. In contrast, it is less perceptible to others. The lambdoidal crest is developed and evident. The basisphenoid pits are deep. Palate arched. The upper incisors are fused at the bases and divergent at the tips. Some skull measurements are presented in Table 1.
Identification.
 Externally, the forearm <65 mm, and the short ears (averaging <34 mm in both sexes) differentiate this species from the largest members of Eumops (E. chimaera, Gregorin, Moras, Acosta, Vasconcellos, Poma, dos Santos & Paca, 2016, E. dabbenei O. Thomas, 1914, E. perotis (Schinz, 1821), and Eumops trumbulli O. Thomas, 1901), while the small, wide, square-shaped tragus, besides the pale brown pelage coloration, separates it from Eumops auripendulus (G. Schaw, 1800), which presents a pointed tragus and a blackish pelage (Eger 2008).

description: Recent findings suggest Mars may have been a clement environment for the emergence of life, and may even have compared favorably to Earth in this regard. These findings have revived interest in the hypothesis that prebiotically important molecules or even nascent life may have formed on Mars and been transferred to Earth. UV light plays a key role in prebiotic chemistry. Characterizing the early Martian surface UV environment is key to understanding how Mars compares to Earth as a venue for prebiotic chemistry. Here, we present two-stream multi-layer calculations of the UV surface radiance on Mars at 3.9 Ga, to constrain the surface UV environment as a function of atmospheric state. We explore a wide range of atmospheric pressures, temperatures and compositions, corresponding to the diversity of Martian atmospheric states consistent with available constraints. We include the effects of clouds and dust. We calculate dose rates to quantify the effect of different atmospheric states on UV-sensitive prebiotic chemistry. We find that for normative clear-sky CO2-H2O atmospheres, the UV environment on young Mars is comparable to young Earth. This similarity is robust to moderate cloud cover: thick clouds ($τ$>100) are required to significantly affect the Martian UV environment, because cloud absorption is degenerate with atmospheric CO2. On the other hand, absorption from SO2, H2S, and dust is nondegenerate with CO2, meaning if they can build up to high levels, surface UV fluence will be suppressed. These absorbers have spectrally variable absorption, meaning that their presence affects prebiotic pathways in different ways. In particular, high SO2 environments may admit UV fluence that favors pathways conducive to abiogenesis over pathways unfavorable to it. However, better measurements of the spectral quantum yields of these pathways are required to evaluate this hypothesis definitively.

description: Future experiments seeking to measure the neutron electric dipole moment (nEDM) require stable and homogeneous magnetic fields. Normally these experiments use a coil internal to a passively magnetically shielded volume to generate the magnetic field. The stability of the magnetic field generated by the coil within the magnetically shielded volume may be influenced by a number of factors. The factor studied here is the dependence of the internally generated field on the magnetic permeability $μ$ of the shield material. We provide measurements of the temperature-dependence of the permeability of the material used in a set of prototype magnetic shields, using experimental parameters nearer to those of nEDM experiments than previously reported in the literature. Our measurements imply a range of $\frac{1}μ\frac{dμ}{dT}$ from 0-2.7\%/K. Assuming typical nEDM experiment coil and shield parameters gives $\fracμ{B_0}\frac{dB_0}{dμ}=0.01$, resulting in a temperature dependence of the magnetic field in a typical nEDM experiment of $\frac{dB_0}{dT}=0-270$~pT/K for $B_0=1~μ$T. The results are useful for estimating the necessary level of temperature control in nEDM experiments.

description: One proposed method for spacecraft to reach nearby stars is by accelerating sails using either solar radiation pressure or directed energy. This idea constitutes the thesis behind the Breakthrough Starshot project, which aims to accelerate a gram-mass spacecraft up to one-fifth the speed of light towards Proxima Centauri. For such a case, the combination of the sail's low mass and relativistic velocity render previous treatments formally incorrect, including that of Einstein himself in his seminal 1905 paper introducing special relativity. To address this, we present formulae for a sail's acceleration, first in response to a single photon and then extended to an ensemble. We show how the sail's motion in response to an ensemble of incident photons is equivalent to that of a single photon of energy equal to that of the ensemble. We use this 'principle of ensemble equivalence' for both perfect and imperfect mirrors, enabling a simple analytic prediction of the sail's velocity curve. Using our results and adopting putative parameters for Starshot, we estimate that previous relativistic treatments underestimate the spacecraft's terminal velocity by ~50m/s for the same incident energy, sufficient to miss a target by several Earth radii. Additionally, we use a simple model to predict the sail's temperature and diffraction beam losses during the laser firing period, allowing us to estimate that for firing times of a few minutes and operating temperatures below 300C (573K), Starshot will require a sail of which absorbs less than 1 in 260,000 photons.

description: SN Hun248 was classified as a nonterminal eruption (a SN "impostor") from a directly identified and highly variable cool hypergiant star. The 2014 outburst achieved peak luminosity equivalent to that of the historic eruption of luminous blue variable (LBV) Eta Car, and exhibited a multipeaked optical light curve that rapidly faded after ~100 days. We report ultraviolet (UV) through optical observations of SN Hunt248 with the Hubble Space Telescope (HST) about 1 yr after the outburst, and mid-infrared observations with the Spitzer Space Telescope before the burst and in decline. The HST data reveal a source that is a factor of ~10 dimmer in apparent brightness than the faintest available measurement of the precursor star. The UV-optical spectral energy distribution (SED) requires a strong Balmer continuum, consistent with a hot B4-B5 photosphere attenuated by grey circumstellar extinction. Substantial mid-infrared excess of the source is consistent with thermal emission from hot dust with a mass of 10^{-6} - 10^{-5} MSun and a geometric extent that is comparable to the expansion radius of the ejecta from the 2014 event. SED modeling indicates that the dust consists of relatively large grains (>0.3 um), which could be related to the grey circumstellar extinction that we infer for the UV-optical counterpart. Revised analysis of the precursor photometry is also consistent with grey extinction by circumstellar dust, and suggests that the initial mass of the star could be twice as large as previously estimated (nearly ~60 MSun). Reanalysis of the earlier outburst data shows that the peak luminosity and outflow velocity of the eruption are consistent with a trend exhibited by stellar merger candidates, prompting speculation that SN Hunt248 may also have stemmed from a massive stellar merger or common-envelope ejection.

description: We investigate the static interquark potential for the three-quark system in SU(3) lattice gauge theory at zero temperature by using Monte Carlo simulations. We extract the potential from the correlation function of the three Polyakov loops, which are computed by employing the multilevel algorithm. We obtain remarkably clean results of the three-quark potential for O(200) sets of the three-quark configurations of various sizes and geometries including not only the cases that three quarks are put at the vertices of acute, right, and obtuse triangles, but also the extreme cases such that three quarks are put in line. We find several new interesting features of the three-quark potential and then discuss its possible functional form.

description: We present a dispersive analysis of the decay amplitude for $η'\toηππ$ that is based on the fundamental principles of analyticity and unitarity. In this framework, final-state interactions are fully taken into account. Our dispersive representation relies only on input for the $ππ$ and $πη$ scattering phase shifts. Isospin symmetry allows us to describe both the charged and neutral decay channel in terms of the same function. The dispersion relation contains subtraction constants that cannot be fixed by unitarity. We determine these parameters by a fit to Dalitz-plot data from the VES and BES-III experiments. We study the prediction of a low-energy theorem and compare the dispersive fit to variants of chiral perturbation theory.

description:
Shifts in the hydrological cycle, such as the location and magnitude of seasonal precipitation, are changing as a result of current climate change. The Eocene, as the warmest epoch during the Cenozoic, is increasingly used as a test of our understanding of how broad-scale features of the climate system respond to greenhouse gas forcing. Here we demonstrate an attempt to reconstruct hydrology of northwest Europe by assessing the riverine input into the Anglo-Paris Basin (an adjacent basin to the Paleo North Sea) during the Lutetian. Marginal seas, like the Anglo-Paris Basin, are well-placed to track seasonal atmospheric variations as well as changes in fluvial discharge.

For our reconstruction we measured stable oxygen (δ18O) and clumped isotopes (∆47) in combination with spatially-resolved Ba/Ca ratios in pristinely preserved bivalve shells (Venericor planicosta). The combined isotope systems were used for the calculation of temperature as well as to identify salinity changes. Barium was simultaneously employed as proxy for terrigenous input. To further evaluate the terrigenous origin of the elevated barium that is frequently observed within these samples, we also measured spatially-resolved strontium isotopic ratios (87Sr/86Sr) by LA-MC-ICP-MS.

The Ba/Ca record displays an invariant background with large, reoccurring peaks, indicating episodic enhanced riverine input into the basin. The periodic freshwater discharge is also visible within the isotope record that shows a variable δ18OSW (+2 to -4‰), pointing to major changes in salinity. These periods are preferentially linked to warmer temperature, therefore representing a primary wet season during summer times.

description: Results are presented of direct numerical simulations of incompressible, homogeneous magnetohydrodynamic turbulence without a mean magnetic field, subject to different mechanical forcing functions commonly used in the literature. Specifically, the forces are negative damping (which uses the large-scale velocity field as a forcing function), a nonhelical random force, and a nonhelical static sinusoidal force (analogous to helical ABC forcing). The time evolution of the three ideal invariants (energy, magnetic helicity and cross helicity), the time-averaged energy spectra, the energy ratios and the dissipation ratios are examined. All three forcing functions produce qualitatively similar steady states with regards to the time evolution of the energy and magnetic helicity. However, differences in the cross helicity evolution are observed, particularly in the case of the static sinusoidal method of energy injection. Indeed, an ensemble of sinusoidally-forced simulations with identical parameters shows significant variations in the cross helicity over long time periods, casting some doubt on the validity of the principle of ergodicity in systems in which the injection of helicity cannot be controlled. Cross helicity can unexpectedly enter the system through the forcing function and must be carefully monitored.

GEO Infrastructure, Open Data and Open Knowledge Workshop, 2023
Creators: name: Group on Earth Observations
Publisher: name: GEO Knowledge Hub
Year: 2023

description: This Knowledge Resource corresponds to the session "GEO Infrastructure" during Open Knowledge Workshop 2023, Geneva, Switzerland.
The GEO Infrastructure needs to evolve to respond to the evolution of user needs and the emergence of new initiatives, platforms, and communities. Throughout the entire workshop, these aspects, whether technical (space and in situ data, data cubes, EO applications, clouds, licenses) or community-related (capacity development, national GEOs, youth engagement), have been discussed and reported back to the audience for discussion, also including a focus on Regional nodes. Moreover, this new GEO infrastructure will pave the way for the transition from open data to open knowledge that GEO has started with the GEO Knowledge Hub and the adoption of the Statement on Open Knowledge.
Objectives
Engage a discussion about the evolution of the GEO infrastructure, and how to integrate the various new components discussed in previous sessions.

description: We present a general purpose Monte Carlo program for the calculation of the radiative muon decay $μ\to e\,ν\barνγ$ and the radiative decays $τ\to e\, ν\barνγ$ and $τ\toμ\,ν\barνγ$ at next-to-leading order in the Fermi theory. The full dependence on the lepton masses and polarization of the initial-sate lepton are kept. We study the branching ratios for these processes and show that fully-differential next-to-leading order corrections are important for addressing a tension between BaBar's recent measurement of the branching ratio $\mathcal{B}(τ\to e\, ν\barνγ)$ and the Standard Model prediction. In addition, we study various distributions of the process $μ\to e\,ν\barνγ$ and obtain precise predictions for the irreducible background to $μ\to e γ$ searches, tailored to the geometry of the MEG detector.

description: Investigation of the resonances $X(4140)$ and $X(4274)$, which were recently confirmed by the LHCb Collaboration [1], is carried out by treating them as the color triplet and sextet $[cs][\bar{c}\bar {s}]$ diquark-antidiquark states with the spin-parity $J^{P}=1^{+}$, respectively. We calculate the masses and meson-current couplings of these tetraquarks in the context of QCD two-point sum rule method by taking into account the quark, gluon and mixed vacuum condensates up to eight dimensions. We also study the vertices $X(4140)J/ψϕ$ and $X(4274)J/ψϕ$, and evaluate corresponding strong couplings $g_{X(4140)J/ψϕ}$ and $ g_{X(4274)J/ψϕ}$ by means of QCD light-cone sum rule method, and a technique of the soft-meson approximation. In turn, these couplings contain a required information to determine the width of the $X(4140)\to J/ψϕ$ and $X(4274) \to J/ψϕ$ decay channels. We compare our results for the masses and decay widths of the $X(4140)$ and $X(4274)$ resonances with the LHCb data, and alternative theoretical predictions.

Morphological description.
Dorsal pelage with a uniform chocolate brown color and shorter at the shoulders (2–3 mm). Ventral fur is slightly bicolored, with the basal portion of hairs chocolate brown and the tips varying between dark brownish and black shade.
Skull with an inflated rostrum and a rounded braincase. Infraorbital foramen opens laterally in frontal view. Upper incisors spatulated. Occipital complex with a rectangular shape (Fig. 10). Canines projected anteriorly. The nasal process in males is well-developed. Basioccipital pits moderately depth. Lambdoidal and sagittal crests well-developed. Mastoid process oriented ventrally in posterior view. The mandible has a developed angular process and a pair of bilobed incisors. Some skull measurements are shown in Table 2.
* This variable was incorrectly measured: Loureiro et al. (2018 b) measured from the base of the tympanic bullae and not from the base of the condyle.
Identification.
 The unicolored dorsal pelage, the infraorbital foramen opens laterally in frontal view, the upper incisors spatulated, and the rectangular-shaped occipital complex differentiate the individuals of this species from their morphologically closest related congeners: Molossus coibensis J. A. Allen, 1904, M. currentium O. Thomas, 1901, and M. molossus (Pallas, 1766) (Gregorin et al. 2011; Loureiro et al. 2018 a, 2018 b).

Stacking machine learning classifiers to identify Higgs bosons at the LHC

description: Machine learning (ML) algorithms have been employed in the problem of classifying signal and background events with high accuracy in particle physics. In this paper, we compare the performance of a widespread ML technique, namely, \emph{stacked generalization}, against the results of two state-of-art algorithms: (1) a deep neural network (DNN) in the task of discovering a new neutral Higgs boson and (2) a scalable machine learning system for tree boosting, in the Standard Model Higgs to tau leptons channel, both at the 8 TeV LHC. In a cut-and-count analysis, \emph{stacking} three algorithms performed around 16\% worse than DNN but demanding far less computation efforts, however, the same \emph{stacking} outperforms boosted decision trees. Using the stacked classifiers in a multivariate statistical analysis (MVA), on the other hand, significantly enhances the statistical significance compared to cut-and-count in both Higgs processes, suggesting that combining an ensemble of simpler and faster ML algorithms with MVA tools is a better approach than building a complex state-of-art algorithm for cut-and-count.

description: Models in which dark matter particles communicate with the visible sector through a pseudoscalar mediator are well-motivated both from a theoretical and from a phenomenological standpoint. With direct detection bounds being typically subleading in such scenarios, the main constraints stem either from collider searches for dark matter, or from indirect detection experiments. However, LHC searches for the mediator particles themselves can not only compete with -- or even supersede -- the reach of direct collider dark matter probes, but they can also test scenarios in which traditional monojet searches become irrelevant, especially when the mediator cannot decay on-shell into dark matter particles or its decay is suppressed. In this work we perform a detailed analysis of a pseudoscalar-mediated dark matter simplified model, taking into account a large set of collider constraints and concentrating on the parameter space regions favoured by cosmological and astrophysical data. We find that mediator masses above 100-200~GeV are essentially excluded by LHC searches in the case of large couplings to the top quark, while forthcoming collider and astrophysical measurements will further constrain the available parameter space.

description: We study what happens to the Nucleon, Delta and Omega baryons in the hadronic gas and the quark-gluon plasma, with particular interest in parity doubling and its emergence as the plasma is heated. This is done using simulations of lattice QCD, employing the FASTSUM anisotropic Nf=2+1 ensembles, with four temperatures below and four above the deconfinement transition temperature. Below Tc we find that the positive-parity groundstate masses are largely temperature independent, whereas the negative-parity ones are reduced considerably as the temperature increases. This may be of interest for heavy-ion phenomenology. Close to the transition, the masses are nearly degenerate, in line with the expectation from chiral symmetry restoration. Above Tc we find a clear signal of parity doubling in all three channels, with the effect of the heavier s quark visible.
