description: Magnetic field is unstable in a medium with time-independent chiral conductivity. Owing to the chiral anomaly, the electromagnetic field and the medium exchange helicity which results in time-evolution of the chiral conductivity. Using the fastest growing momentum and helicity state of the vector potential as an ansatz, the time-evolution of the chiral conductivity and magnetic field is solved analytically. The solution for the hot and cold equations of state shows that the magnetic field does not develop an instability due to he helicity conservation. Moreover, it develops a peak only if a significant part of the \emph{initial} helicity is stored in the medium. The initial helicity determines the height and position of the peak.

description: We perform a thorough analysis of the spectral statistics of experimental molecular resonances, of bosonic erbium $^{166}$Er and $^{168}$Er isotopes, produced as a function of magnetic field($B$) by Frisch et al. [Nature 507, (2014) 475], utilizing some recently derived surmises which interpolate between Poisson and GOE and without unfolding. Supplementing this with an analysis using unfolded spectrum, it is shown that the resonances are close to semi-Poisson distribution. There is an earlier claim of missing resonances by Molina et al. [Phys. Rev. E 92, (2015) 042906]. These two interpretations can be tested by more precise measurements in future experiments.

description: Up to now, the excited charmed and bottom baryon states are still not well studied both experimentally and theoretically. In the present paper, we predict the mass of $Ω_b^*$, the only $L = 0$ baryon state which has not been observed, to be 6069.2 MeV. The spectra of charmed and bottom baryons with the orbital angular momentum $L = 1$ are studied in two popular constituent quark models, the Goldstone boson exchange (GBE) and the one gluon exchange (OGE) hyperfine interaction models, respectively. Inserting the latest experimental data from the "Review of Particle Physics", we find that in the GBE model, there exist some multiplets ($Σ_{c(b)}$, $Ξ'_{c(b)}$ and $Ω_{c(b)}$) which total spins of three quarks in their lowest energy states are 3/2, but in the OGE model there is no such phenomenon. This is the most important difference between the GBE and OGE models. These results can be tested in the near future. We suggest more efforts to study the excited charmed and bottom baryons both theoretically and experimentally, not only for the abundance of baryon spectra, but also for determining which hyperfine interaction model is realized in nature.

description: We present RDCL 3D, a "model agnostic" web framework for the design and composition of NFV services and components. The framework allows editing and validating the descriptors of services and components both textually and graphically and supports the interaction with external orchestrators or with deployment and execution environments. RDCL 3D is open source and designed with a modular approach, allowing developers to "plug in" the support for new models. We describe several advances with respect to the NFV state of the art, which have been implemented with RDCL 3D. We have integrated in the platform the latest ETSI NFV ISG model specifications for which no parsers/validators were available. We have also included in the platform the support for OASIS TOSCA models, reusing existing parsers. Then we have considered the modelling of components in a modular software router (Click), which goes beyond the traditional scope of NFV. We have further developed this approach by combining traditional NFV components (Virtual Network Functions) and Click elements in a single model. Finally, we have considered the support of this solution using the Unikernels virtualization technology.

description: The very nearby Type Ia supernova 2014J in M82 offers a rare opportunity to study the physics of thermonuclear supernovae at extremely late phases ($\gtrsim$800 days). Using the Hubble Space Telescope (HST), we obtained six epochs of high precision photometry for SN 2014J from 277 days to 1181 days past the $B-$band maximum light. The reprocessing of electrons and X-rays emitted by the radioactive decay chain $^{57}$Co$\rightarrow ^{57}$Fe are needed to explain the significant flattening of both the $F606W$-band and the pseudo-bolometric light curves. The flattening confirms previous predictions that the late-time evolution of type Ia supernova luminosities requires additional energy input from the decay of $^{57}$Co (Seitenzahl et al. 2009). By assuming the $F606W$-band luminosity scales with the bolometric luminosity at $\sim$500 days after the $B-$band maximum light, a mass ratio $^{57}$Ni/$^{56}$Ni$\sim$0.065$_{-0.004}^{+0.005}$ is required. This mass ratio is roughly $\sim$3 times the solar ratio and favors a progenitor white dwarf with a mass near the Chandrasekhar limit. A similar fit using the constructed pseudo-bolometric luminosity gives a mass ratio $^{57}$Ni/$^{56}$Ni$\sim$0.066$_{-0.008}^{+0.009}$. Astrometric tests based on the multi-epoch HST ACS/WFC images reveal no significant circumstellar light echoes in between 0.3 pc and 100 pc (Yang et al. 2017) from the supernova.

description: A deformed dielectric microcavity is used as an experimental platform for the analysis of the statistics of chaotic resonances, in the perspective of testing fractal Weyl laws at optical frequencies. In order to surmount the difficulties that arise from reading strongly overlapping spectra, we exploit the mixed nature of the phase space at hand, and only count the high-Q whispering-gallery modes (WGMs) directly. That enables us to draw statistical information on the more lossy chaotic resonances, coupled to the high-Q regular modes via dynamical tunneling. Three different models [classical, Random-Matrix-Theory (RMT) based, semiclassical] to interpret the experimental data are discussed. On the basis of least-squares analysis, theoretical estimates of Ehrenfest time, and independent measurements, we find that a semiclassically modified RMT-based expression best describes the experiment in all its realizations, particularly when the resonator is coupled to visible light, while RMT alone still works quite well in the infrared. In this work we reexamine and substantially extend the results of a short paper published earlier [L. Wang, D. Lippolis, Z.-Y. Li, X.-F. Jiang, Q. Gong, and Y.-F. Xiao, Phys. Rev. E 93, 040201(R) (2016)].

Can the Helium-Enriched Main-Sequence Donor Scenario Hide Enough Hydrogen to Explain Type Ia Supernovae?

description: Hydrodynamical simulations predict that a large amount of hydrogen (>0.1 solar masses) is removed from a hydrogen-rich companion star by the SN explosion in the single-degenerate scenario of Type Ia supernovae (SNe Ia). However, non-detection of hydrogen-rich material in the late-time spectra of SNe Ia suggests that the hydrogen mass stripped from the progenitor system is <0.001-0.058 solar masses. In this letter we include thermohaline mixing into self-consistent binary evolution calculations for the helium-enriched main-sequence (HEMS) donor channel of SNe Ia for the first time. We find that the swept-up hydrogen masses expected in this channel are around 0.10-0.17 solar masses, which is higher than the observational limits, although the companion star is strongly helium-enriched when the SN explodes. This presents a serious challenge to the HEMS donor channel.

description: Two integrable $U(1)$-invariant peakon equations are derived from the NLS hierarchy through the tri-Hamiltonian splitting method. A Lax pair, a recursion operator, a bi-Hamiltonian formulation, and a hierarchy of symmetries and conservation laws are obtained for both peakon equations. These equations are also shown to arise as potential flows in the NLS hierarchy by applying the NLS recursion operator to flows generated by space translations and $U(1)$-phase rotations on a potential variable. Solutions for both equations are derived using a peakon ansatz combined with an oscillatory temporal phase. This yields the first known example of a peakon breather. Spatially periodic counterparts of these solutions are also obtained.

description:
The Atacama Pediplain (AP) is a major element in the Atacama Desert landscape, commonly used as an indicator of climatic and tectonic stability. We choose the El Salado Canyon area (26°S) that longitudinally exposes the AP to study its relationship with the Andean forearc evolution, combining geomorphologic and stratigraphic observation with new geochronological data (40Ar/39Ar biotite ages on ignimbrites, and 21Ne exposure ages on quartz-clasts). The AP alluvial deposition occurred in two episodes of alluvial backfilling spatially and temporally separated from each other (Early Miocene - Mid Miocene in the Precordillera, and Mid Miocene - Early Pliocene in the Central Depression), and both triggered by semiarid to arid conditions restricted to the higher Precordillera. Both episodes occurred despite the regionally recorded Mid Miocene onset of hyperarid conditions, revealing the local control of the upstream humidity in the downstream sedimentation. Clustered exposure ages from the Pliocene reveal the abandonment of the alluvial plains due to the incision of the El Salado Canyon, whereas younger and individual exposure ages from the Early Pleistocene, explained by minor surficial activity, reveal a climatic control on the surfaces after the incision that ended with the increase of the Pleistocene hyperaridity. Therefore, the development of alluvial deposition despite the regional Mid Miocene hyperaridity, and the development of a deep canyon incision after the last recorded Andean uplift, reveals that the AP has been strongly influenced by local conditions that do not allow its use as a general marker of a single climatic or tectonic event.

description: We propose a geometric assumption on nonnegative data matrices such that under this assumption, we are able to provide upper bounds (both deterministic and probabilistic) on the relative error of nonnegative matrix factorization (NMF). The algorithm we propose first uses the geometric assumption to obtain an exact clustering of the columns of the data matrix; subsequently, it employs several rank-one NMFs to obtain the final decomposition. When applied to data matrices generated from our statistical model, we observe that our proposed algorithm produces factor matrices with comparable relative errors vis-à-vis classical NMF algorithms but with much faster speeds. On face image and hyperspectral imaging datasets, we demonstrate that our algorithm provides an excellent initialization for applying other NMF algorithms at a low computational cost. Finally, we show on face and text datasets that the combinations of our algorithm and several classical NMF algorithms outperform other algorithms in terms of clustering performance.

description: Vector boson dark matter (DM) appears in $SU(2)_N$ extension ($N$ stands for neutral) of Standard Model (SM) where an additional global $U(1)_P$ symmetry is assumed and results in a generalized lepton number defined as: $L=P+T_{3N}$. Breaking of $U(1)_P$ leads to the breaking of $L$ to $(-1)^L$, thus stabilizing DM through modified $R=(-1)^{3B+L+2J}$. This model, already discussed in literature, offers several novel features to elaborate upon. For example, $t$-channel annihilation and dominant $s$-channel direct search, along with co-annihilation, helps the DM to evade stringent direct search bounds from LUX and XENON1T after satisfying relic density constraints. On the other hand, the exotic particles of the model can be produced at the Large Hadron Collider (LHC) yielding multilepton final states. Hadronically quiet four lepton signal with large missing energy, in specific, is shown to provide a smoking gun signature of such a framework. We study the details of $E(6) \to SM \otimes SU(2)_N$ breaking patterns (through D-parity odd/even cases) which yield important phenomenological consequences.

description: A pair of type-II Dirac cones in PdTe$_2$ was recently predicted by theories and confirmed in experiments, making PdTe$_2$ the first material that processes both superconductivity and type-II Dirac fermions. In this work, we study the evolution of Dirac cones in PdTe$_2$ under hydrostatic pressure by the first-principles calculations. Our results show that the pair of type-II Dirac points disappears at 6.1 GPa. Interestingly, a new pair of type-I Dirac points from the same two bands emerges at 4.7 GPa. Due to the distinctive band structures compared with those of PtSe$_2$ and PtTe$_2$, the two types of Dirac points can coexist in PdTe$_2$ under proper pressure (4.7-6.1 GPa). The emergence of type-I Dirac cones and the disappearance of type-II Dirac ones are attributed to the increase/decrease of the energy of the states at $Γ$ and $A$ point, which have the anti-bonding/bonding characters of interlayer Te-Te atoms. On the other hand, we find that the superconductivity of PdTe$_2$ slightly decreases with pressure. The pressure-induced different types of Dirac cones combined with superconductivity may open a promising way to investigate the complex interactions between Dirac fermions and superconducting quasi-particles.

For the values of shear modulus that are close enough to zero, so that the effect of the solid on large-scale anisotropies remains within cosmic variance, we find that there is an observable effect of the solid on small-scale anisotropies.

description:
As part of a major German effort towards a national research data infrastructure, the NFDI4Earth (www.nfdi4earth.de) brings together researchers in the Earth System Sciences, their data, tools, and services to address their digital needs. NFDI4Earth is a community-driven process providing researchers with access to FAIR, coherent, and open ESS data, innovative research data management (RDM) and data science methods. It will do so by developing a central infrastructure that provides access to all ESS data sources, and tools via the OneStop4All to access, connect, visualise and generally research these.

The NFDI4Earth aims from early on for an open communication to and active involvement of the ESS community and the interested public, particularly its participants and interest groups. The structure of the NFDI4Earth was already presented on previous editions of this conference series and will therefore only be briefly summarised. The focus of this talk will be on the developments within the NFDI4Earth, its services and products. A lot has happened since its official start in January 2022, e.g., decisions on the software stacks, consideration of the various use cases, development of the knowledge hub and living handbook, starting of various interest groups, start of 14 pilot projects. Most importantly, we will point out where you can (and hopefully will) engage in the further development of the NFDI4Earth services and products because it is your feedback and participation that will allow us to develop the NFDI4Earth as close to the needs and expectations of the community as possible.

description: Plasmon resonances are known to amplify the electromagnetic fields near metallic nanostructures. Therefore, they are considered to provide a promising scheme to generate extreme-ultraviolet harmonics, using low power drivings. During high-order harmonic generation (HHG), the driving and harmonic fields accumulate a phase difference as they propagate through the target. In a typical set-up -a laser focused into a gas jet or cell- the propagation distances amount to several wavelengths, and the cumulative phase-mismatch affects strongly the efficiency and properties of the harmonic emission. In contrast, HHG in metallic nanostructures is considered to overcome this limitations, as the common sources of phase mismatch -optical density and focusing geometry- are negligible for subwavelength propagation distances. Nevertheless, in this letter we demonstrate that phase matching still plays a relevant role in HHG from nanostructures. Our computations attribute this to the non-perturbative character of HHG, that links the phase of the harmonics to the intensity distribution of the driving field. We also show that widely used applications of phase matching control, such as quantum path selection and the increase of contrast in attosecond pulse generation, are also feasible at the nanoscale.

description: We report on the dynamics of the spin-1/2 quasi-one-dimensional frustrated magnet LiCuVO$\mathrm{_4}$ measured by nuclear spin relaxation in high magnetic fields 10--34 T, in which the ground state has spin-density-wave order. The spin fluctuations in the paramagnetic phase exhibit striking anisotropy with respect to the magnetic field. The transverse excitation spectrum probed by $^{51}$V nuclei has an excitation gap, which increases with field. On the other hand, the gapless longitudinal fluctuations sensed by $^7$Li nuclei grow with lowering temperature, but tend to be suppressed with increasing field. Such anisotropic spin dynamics and its field dependence agree with the theoretical predictions and are ascribed to the formation of bound magnon pairs, a remarkable consequence of the frustration between ferromagnetic nearest neighbor and antiferromagnetic next-nearest-neighbor interactions.

description: Cosmic-ray anti-deuterium and anti-helium have long been suggested as probes of dark matter, as their secondary astrophysical production was thought extremely scarce. But how does one actually predict the secondary flux? Anti-nuclei are dominantly produced in pp collisions, where laboratory cross section data is lacking. We make a new attempt at tackling this problem by appealing to a scaling law of nuclear coalescence with the physical volume of the hadronic emission region. The same volume is probed by Hanbury Brown-Twiss (HBT) two-particle correlations. We demonstrate the consistency of the scaling law with systems ranging from central and off-axis AA collisions to pA collisions, spanning 3 orders of magnitude in coalescence yield. Extending the volume scaling to the pp system, HBT data allows us to make a new estimate of coalescence, that we test against preliminary ALICE pp data. For anti-helium the resulting cross section is 1-2 orders of magnitude higher than earlier estimates. The astrophysical secondary flux of anti-helium could be within reach of a five-year exposure of AMS02.

description: In present work, we investigate the spectrum of several low-lying $sscq\bar{q}$ pentaquark configurations employing the constituent quark model, within which the hyperfine interaction between quarks is taken to be mediated by Goldstone boson exchange. Our numerical results show that four $sscq\bar{q}$ configurations with $J^{P}=1/2^{-}$ or $J^{P}=3/2^{-}$ lie at energies very close to the recently observed five $Ω_{c}^{0}$ states by LHCb collaboration, this indicates that the $sscq\bar{q}$ pentaquark configurations may form sizable components of the observed $Ω_{c}^{0}$ resonances.

description: Maternal distress is an influential factor for fetal development, including infant temperament. Infant temperament is important as a potential precursor for the development of child psychopathology. It is important to consider the psychosocial influences and context as it relates to maternal distress, particularly social disadvantage. Although the association of social disadvantage with maternal distress is documented, questions remain about the mechanisms through which risk factors (socioeconomic status area deprivation, subjective social status, perceived discrimination) influence distress and indirectly may influence offspring temperamental development

description: We extend the Cisinski-Moerdijk-Weiss theory of $\infty$-operads to the equivariant setting to obtain a notion of $G$-$\infty$-operads that encode "equivariant operads with norm maps" up to homotopy. At the root of this work is the identification of a suitable category of $G$-trees together with a notion of $G$-inner horns capable of encoding the compositions of norm maps. Additionally, we follow Blumberg and Hill by constructing suitable variants associated to each of the indexing systems featured in their work.

description: Numerical evidence suggests that for only about $2\%$ of pairs $p,p+2$ of twin primes, $p+2$ has more primitive roots than does $p$. If this occurs, we say that $p$ is exceptional (there are only two exceptional pairs with $5 \leq p \leq 10{,}000$). Assuming the Bateman-Horn conjecture, we prove that at least $0.47\%$ of twin prime pairs are exceptional and at least $65.13\%$ are not exceptional. We also conjecture a precise formula for the proportion of exceptional twin primes.

description: We study transient charges formed in methane clusters following ionization by intense near-infrared laser pulses. Cluster ionization by 400 fs ($I=1 \times 10^{14}$ W/cm$^2$) pulses is highly efficient, resulting in the observation of a dominant C$^{3+}$ ion contribution. The C$^{4+}$ ion yield is very small, but is strongly enhanced by applying a time-delayed weak near-infrared pulse. We conclude that most of the valence electrons are removed from their atoms during the laser-cluster interaction, and that electrons from the nanoplasma recombine with ions and populate Rydberg states when the cluster expands, leading to a \textit{decrease} of the average charge state of individual ions. Furthermore, we find clear bound-state signatures in the electron kinetic energy spectrum, which we attribute to Auger decay taking place in expanding clusters. Such nonradiative processes lead to an \textit{increase} of the final average ion charge state that is measured in experiments. Our results suggest that it is crucial to include both recombination and nonradiative decay processes for the understanding of recorded ion charge spectra.

description:
Palaeontology is unique among scientific disciplines in that it thrives on the exchange of information across diverse communities, both academic and non-academic. However, palaeontological research does not always best serve these communities.  A practice that is prevalent in palaeontology is "parachute science", referring to the practice whereby researchers drop into, collect data and leave without the involvement or interaction with the local community. Put simply, these parachuting palaeontologists are benefitting from the resources of a country and often, the efforts of local people, without giving anything back. Lack of paleontological and scientific involvement with communities in the Global South may be a remnant of colonial-era palaeontology. The history of natural science is inseparable from the history of European colonialism when local specimens were brought to the homeland of the colonisers to be reposited and studied in museums for the sake of the "greater scientific good". The culture of theft and plunder, a legacy of colonialism perpertuates in palaeontology, even now. The drive for discovering the next new extraordinary fossil can be linked to several ethical and legal issues, where fossils are excavated without record and smuggled across borders to finally end up in collections across the world.
On induced action for conformal higher spins in curved background

description: We continue the investigation of the structure of the action for a tower of conformal higher spin fields in non-trivial 4d background metric recently discussed in arXiv:1609.09381. The action is defined as an induced one from path integral of a conformal scalar field in curved background coupled to higher spin fields. We analyse in detail the dependence of the quadratic part of the induced action on the spin 1 and spin 3 fields, determining the presence of a curvature-dependent mixed spin 1 - spin 3 term. One consequence is that the pure spin 3 kinetic term cannot be gauge-invariant on its own beyond the leading term in small curvature expansion. We also compute the non-zero contribution of the 1-3 mixing term to the conformal anomaly c-coefficient. One is thus to determine all such mixing terms before addressing the question of possible vanishing of the total c-coefficient in the conformal higher spin theory.

Parity solitons in nonresonantly driven-dissipative condensate channels

description: We study analytically and numerically the condensation of a driven-dissipative exciton-polariton system using symmetric nonresonant pumping geometries. We show that the lowest condensation threshold solution carries a definite parity as a consequence of the symmetric excitation profile. At higher pump intensities competition between the two parities can result in critical quenching of one and saturation of the other. Using long pump channels, we show that the competition of the condensate parities gives rise to a different type of topologically stable defect propagating indefinitely along the condensate. The defects display repulsive interactions and are characterized by a sustained wavepacket carrying a pair of opposite parity domain walls in the condensate channel.
How to break the density-anisotropy degeneracy in spherical stellar systems

Publisher: name: arXiv
Year: 2017
Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)

description: We present a new non-parametric Jeans code, GravSphere, that recovers the density $ρ(r)$ and velocity anisotropy $β(r)$ of spherical stellar systems, assuming only that they are in a steady-state. Using a large suite of mock data, we confirm that with only line-of-sight velocity data, GravSphere provides a good estimate of the density at the projected stellar half mass radius, $ρ(R_{1/2})$, but is not able to measure $ρ(r)$ or $β(r)$, even with 10,000 tracer stars. We then test three popular methods for breaking this $ρ-β$ degeneracy: using multiple populations with different $R_{1/2}$; using higher order `Virial Shape Parameters' (VSPs); and including proper motion data. We find that two populations provide an excellent recovery of $ρ(r)$ in-between their respective $R_{1/2}$. However, even with a total of $\sim 7,000$ tracers, we are not able to well-constrain $β(r)$ for either population. By contrast, using 1000 tracers with higher order VSPs we are able to measure $ρ(r)$ over the range $0.5 < r/R_{1/2} < 2$ and broadly constrain $β(r)$. Including proper motion data for all stars gives an even better performance, with $ρ$ and $β$ well-measured over the range $0.25 < r/R_{1/2} < 4$. Finally, we test GravSphere on a triaxial mock galaxy that has axis ratios typical of a merger remnant, $[1:0.8:0.6]$. In this case, GravSphere can become slightly biased. However, we find that when this occurs the data are poorly fit, allowing us to detect when such departures from spherical symmetry become problematic.

Pseudogap and Fermi surface in the presence of spin-vortex checkerboard for 1/8-doped lanthanum cuprates

description: Lanthanum family of high-temperature cuprate superconductors is known to exhibit both spin and charge electronic modulations around doping level 1/8. We assume that these modulations have the character of two-dimensional spin-vortex checkerboard and investigate whether this assumption is consistent with the Fermi surface and the pseudogap measured by angle-resolved photo-emission spectroscopy. We also explore the possibility of observing quantum oscillations of transport coefficients in such a background. These investigations are based on a model of non-interacting spin-1/2 fermions hopping on a square lattice and coupled through spins to a magnetic field imitating spin-vortex checkerboard. The main results of this article include (i) calculation of Fermi surface containing Fermi arcs at the positions in the Brillouin zone largely consistent with experiments; (ii) identification of factors complicating the observations of quantum oscillations in the presence of spin modulations; and (iii) investigation of the symmetries of the resulting electronic energy bands, which, in particular, indicates that each band is double-degenerate and, in addition, has at least one conical point, where it touches another double-degenerate band. We discuss possible implications these cones may have for the transport properties and the pseudogap.

description: Die Versorgungsepidemiologie steht vor einem Paradoxon: Obwohl Behandlungsleistungen erheblich ausgebaut und häufiger genutzt werden, kann dennoch kein Absinken der Prävalenzen psychischer Störungen und Symptome verzeichnet werden.
 Im vorliegenden Beitrag werden drei Erklärungsansätze zur Frage diskutiert, inwiefern und warum die Prävalenzen psychischer Störungen trotz erheblicher Investitionen in ihre Versorgung nicht sinken:
 1. Mangelhafte Prävention und Versorgung (zu wenig Prävention, viele Behandlungsbedürftige nicht in Kontakt mit dem Versorgungssystem, Versorgungsleistungen weisen Qualitätsmängel auf, insbesondere mangelnde Vernetzung) 2. Wachsende Morbidität und vermehrter Behandlungsbedarf (Nehmen Risikofaktoren zu und Schutzfaktoren ab? Nimmt (bei gleichbleibenden Prävalenzen) der Behandlungsbedarf zu?) 3. Psychologischer Kulturwandel im Sinne eines verstärkten Bewusstseins für mentale Prozesse (Chancen und Risiken zunehmender »Psychologisierung«, Gesundheitskompetenz versus Übersensibilisierung).
 Diese Erklärungsansätze unterscheiden sich wesentlich in ihren Prämissen und Implikationen. Folgerungen für Gesundheitspolitik und gesellschaftliche Entwicklungsbedarfe werden genannt, und es wird die Frage diskutiert, ob das Mental-Health-System noch weiter ausgebaut werden sollte.
