description: This article discusses applications of Bayesian machine learning for quantum molecular dynamics. One particular formulation of quantum dynamics advocated here is in the form of a machine learning simulator of the Schrödinger equation. If combined with the Bayesian statistics, such a simulator allows one to obtain not only the quantum predictions but also the error bars of the dynamical results associated with uncertainties of inputs (such as the potential energy surface or non-adiabatic couplings) into the nuclear Schrödinger equation. Instead of viewing atoms as undergoing dynamics on a given potential energy surface, Bayesian machine learning allows one to formulate the problem as the Schrödinger equation with a non-parametric distribution of potential energy surfaces that becomes conditioned by the desired dynamical properties (such as the experimental measurements). Machine learning models of the Schrödinger equation solutions can identify the sensitivity of the dynamical properties to different parts of the potential surface, the collision energy, angular momentum, external field parameters and basis sets used for the calculations. This can be used to inform the design of efficient quantum dynamics calculations. Machine learning models can also be used to correlate rigorous results with approximate calculations, providing accurate interpolation of exact results. Finally, there is evidence that it is possible to build Bayesian machine learning models capable of physically extrapolating the solutions of the Schrödinger equation. This is particularly valuable as such models could complement common discovery tools to explore physical properties at Hamiltonian parameters not accessible by rigorous quantum calculations or experiments, and potentially be used to accelerate the numerical integration of the nuclear Schrödinger equation.

description: Zosterops poliogastra erlangeri Neumann
 Zosterops poliogastra erlangeri Neumann, 1908: 60 (Gadat in Gofa).
 Now Zosterops poliogastrus poliogastrus Heuglin, 1861. See Moreau, 1967: 331–332, Fry et al., 2000: 316–317, and van Balen, 2008: 473.
 LECTOTYPE: AMNH 699580, adult male, collected at Gadat, Gamu-Gofa (5 Gofa), Ethiopia, on 31 January 1901, by Oscar Neumann (no. 733). From the Rothschild Collection.
 COMMENTS: In the original description, Neumann listed as his type a male in the Rothschild Collection collected at Gadat on 31 January 1901. There were two such specimens, but Hartert (1920: 432), in listing types in the Rothschild Collection, gave Neumann’s unique field number of the type, thereby designating it the lectotype. Neumann (1908: 60) gave the range of erlangeri as Shoa, Harar, Arussi mountains and the Omo Region. Paralectotypes in AMNH are: AMNH 699578 (Neumann no. 583), male, collected at Gardula, on 13 January 1901; AMNH 699579 (729), male, collected at Gadat, Gamu-Gofa, 31 January 1901; AMNH 699581 (404), female, Alata, Sidamo, 13 December 1900; AMNH 699582 (397), male, Habela, Sidamo, 12 December 1900. Earlier, these specimens were all listed as Z. p. poliogastrus by Neumann (1906: 241–242).
Gadat is shown on the map in Neumann (1902c) at ca. 06.20N, 36.50E.

description: Die Frage, inwieweit sich Historiker literarischer Techniken bedienen und ob die Erklärungs- und Überzeugungskraft ihrer Darstellungen auf vorgegebenen narrativen Strukturen basiert, ist von Geschichtstheoretikern und Historiographiehistorikern der letzten Jahrzehnte viel diskutiert worden. Entsprechend hat sich die Untersuchung historiographischer Werke mit literaturwissenschaftlichen Methoden zu einem komplexen und zunehmend verwirrenden Feld entwickelt. Es gibt freilich keinen Grund zu glauben, narrative Strukturen seien in der Archäologie von geringerer Bedeutung. Trotzdem sind narratologische Überlegungen erst in den letzten Jahren auch auf die Geschichte der Archäologie angewendet worden. Der Nutzen dieser Ansätze lässt sich besonders gut am Beispiel archäologischer Wanderungserzählungen aufzeigen. Weil diese Darstellungen in der Regel weite Zeiträume abdecken und verschiedene historische Akteure und Räume zusammenfassen, greifen Archäologen auf spezifische Erzählstrategien zurück, um ihre Fakten zu sortieren und in mehr oder weniger kohärente Geschichten zu transformieren.

description: In diesem Artikel frage ich nach der theoretischen und methodologischen Tragweite einer Kombination von Begriffsgeschichte und Pierre Bourdieus Habitus- und Feldtheorie. Der Ansatz wird am Beispiel eines Definitionsversuchs völkischen Denkens in der deutschen Prähistorie ausgelotet. In dieser theoretischen Perspektive sind Denkhaltungen auf der semantischen Ebene mit historischen Ereignissen und Prozessen im sozialen Raum, das heißt in diesem Fall im wissenschaftlichen Feld, verknüpft. Auf der einen Seite kann dadurch gezeigt werden, dass völkische Elemente zur Entwicklung der prähistorischen Archäologie als selbständiges Forschungsfeld gehörten. Auf der anderen Seite wird deutlich, dass rassistisches und völkisches Denken das Resultat einer Heteronomisierung der Prähistorie war, die sich während des NS-Regimes massiv verstärkte, als deutsche Prähistoriker versuchten, mit Hilfe einer Zusammenarbeit mit NS-Politikern ihren Forschungsbereich akademisch zu etablieren.

description: The production of the initial state of the QGP in very high-energy $AA$ collisions is discussed within the framework of perturbative QCD and saturation. The next-to-leading order computation of the transverse energy of minijets is reviewed. Saturation of parton production, conjectured to occur at a dynamically determinable perturbative scale, leads to estimates of the initial densities. The final state multiplicities are predicted by assuming an isentropic hydrodynamical further evolution. Comparison with RHIC data is shown.

description: Apoptosis of granulosa cells (GCs) induced by hyperandrogen plays a key role in the pathogenesis of polycystic ovary syndrome (PCOS). However, the mechanism of androgen-induced apoptosis of GCs has not been clarified to date. Recent studies have reported that PDCD4 expression is higher in PCOS patients and might be a key factor in PCOS progression. In this study, we aimed to investigate the role of PDCD4 in regulating apoptosis of human GCs and whether hyperandrogen regulate PDCD4 expression through DNA methylation. Overexpression of PDCD4 in human ovarian granulosa cell line KGN cells promoted cells apoptosis. Meanwhile, expression of caspase-3 and caspase-9 were significantly elevated. High concentration of testosterone treatment resulted in up-regulation of PDCD4 and a significant increase of apoptosis in KGN cells. In addition, knockdown of PDCD4 in KGN cells treated with high concentration of testosterone abolished the hyperandrogen-induced apoptosis. Furthermore, high concentration of testosterone down-regulated DNMT1, DNMT3A and DNMT3B expression and the methylation level in the promoter region of PDCD4 was decreased. In conclusion, PDCD4 can promote apoptosis of human ovarian GCs. The mechanism of hyperandrogen-induced apoptosis may be mediated by PDCD4. Furthermore, the up-regulation of PDCD4 induced by hyperandrogen may through demethylation of its promoter regions.

description: We revisit the problem of plane monochromatic gravitational waves impinging upon a Schwarzschild black hole using complex angular momentum techniques. By extending our previous study concerning scalar and electromagnetic waves [A. Folacci and M. Ould El Hadj, Phys.\, Rev.\, D {\bf 99}, 104079, (2019), arXiv:1901.03965], we provide complex angular momentum representations and Regge pole approximations of the helicity-preserving and helicity-reversing scattering amplitudes and of the total differential scattering cross section. We show, in particular, that for high frequencies (i.e., in the short-wavelength regime), a small number of Regge poles permits us to describe numerically with very good agreement the black hole glory and the orbiting oscillations and we then provide a semiclassical approximation that unifies these two phenomena.

Measuring the delay time distribution of binary neutron stars. I. Through Scaling Relations of the Host Galaxies of Gravitational Wave Events

Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)

subject: FOS: Physical sciences

description: The delay time distribution of (DTD) of binary neutron stars (BNS) remains poorly constrained, mainly by the small known population of Galactic binaries, the properties of short gamma-ray burst host galaxies, and inferences from $r$-process enrichment. In the new era of BNS merger detections through gravitational waves (GW), a new route to the DTD is the demographics of the host galaxies, localized through associated electromagnetic counterparts. This approach takes advantage of the correlation between star formation history (SFH) and galaxy mass, such that the convolution of the SFH and DTD impacts the BNS merger rate as a function of galaxy mass. Here we quantify this approach for a power law DTD governed by two parameters: the power law index ($Γ$) and a minimum delay time ($t_{\rm min}$). Under the reasonable assumption that EM counterparts are likely only detectable in the local universe, accessible by the current generation of GW detectors, we study how many host galaxies at $z\sim 0$ are required to constrain the DTD parameters. We find that the DTD is mainly imprinted in the statistics of massive galaxies (stellar mass of $M_*\gtrsim 10^{10.5}$ M$_\odot$, comparable to the host galaxy of GW170817). Taking account of relevant uncertainties we find that $\mathcal{O}(10^3)$ host galaxies are required to constrain the DTD; for a fixed value of $t_{\rm min}$, as done in previous analyses of the DTD, $\mathcal{O}(10^2)$ host galaxies will suffice. Such a sample might become available within the next two decades, prior to the advent of third-generation GW detectors.

Resistivity near a nematic quantum critical point: Impact of acoustic phonons

Publisher: name: arXiv

Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)

description: We revisit the issue of the resistivity of a two-dimensional electronic system tuned to a nematic quantum critical point (QCP), focusing on the non-trivial impact of the coupling to the acoustic phonons. Due to the unavoidable linear coupling between the electronic nematic order parameter and the lattice strain fields, long-range nematic interactions mediated by the phonons emerge in the problem. By solving the semi-classical Boltzmann equation in the presence of scattering by impurities and nematic fluctuations, we determine the temperature-dependence of the resistivity as the nematic QCP is approached. One of the main effects of the nemato-elastic coupling is to smooth the electronic non-equilibrium distribution function, making it approach the simple cosine angular dependence even when the impurity scattering is not too strong. We find that at temperatures lower than a temperature scale set by the nemato-elastic coupling, the resistivity shows the $T^2$ behavior characteristic of a Fermi liquid. This is in contrast to the $T^{4/3}$ low-temperature behavior expected for a lattice-free nematic quantum critical point. More importantly, we show that the effective resistivity exponent $α_\text{eff}(T)$ in $ρ(T)-ρ_0\sim T^{α_\text{eff}(T)}$ displays a pronounced temperature dependence, implying that a nematic QCP cannot generally be characterized by a simple resistivity exponent. We discuss the implications of our results to the interpretation of experimental data, particularly in the nematic superconductor FeSe$_{1-x}$S$_x$.

description: We derive the random-phase approximation for spin excitations in general multi-band Hubbard models, starting from a collinear ferromagnetic Hartree-Fock ground state. The results are compared with those of a recently introduced variational many-body approach to spin-waves in itinerant ferromagnets. As we exemplify for Hubbard models with one and two bands, the two approaches lead to qualitatively different results. The discrepancies can be traced back to the fact that the Hartree-Fock theory fails to describe properly the local moments which naturally arise in a correlated-electron theory.

description: We have numerically investigated whether or not a mean-field theory of spin textures generate fictitious flux in the doped two dimensional $t-J$-model. First we consider the properties of uniform systems and then we extend the investigation to include models of striped phases where a fictitious flux is generated in the domain wall providing a possible source for lowering the kinetic energy of the holes. We have compared the energetics of uniform systems with stripes directed along the (10)- and (11)-directions of the lattice, finding that phase-separation generically turns out to be energetically favorable. In addition to the numerical calculations, we present topological arguments relating flux and staggered flux to geometric properties of the spin texture. The calculation is based on a projection of the electron operators of the $t-J$ model into a spin texture with spinless fermions.

description: In the field of cavity optomechanics, proposals for quantum nondemolition (QND) measurements of phonon number provide a promising avenue by which one can study the quantum nature of nanoscale mechanical resonators. Here we investigate these QND measurements for an optomechanical system whereby quadratic coupling arises due to shared symmetries between a single optical resonance and a mechanical mode. We establish a relaxed limit on the amount of linear coupling that can exist in this type of system while still allowing for QND measurements of mechanical Fock states. The ability to perform optomechanical QND measurements of this nature would allow one to probe the decoherence of these mesoscopic states, providing an experimental test bed for quantum collapse theories.
The Power Spectra of Polarized, Dusty Filaments

description: We develop an analytic model for the power spectra of polarized filamentary structures as a way to study the Galactic polarization foreground to the Cosmic Microwave Background. Our approach is akin to the cosmological halo-model framework, and reproduces the main features of the Planck 353 GHz power spectra. We model the foreground as randomly-oriented, three-dimensional, spheroidal filaments, accounting for their projection onto the sky. The main tunable parameters are the distribution of filament sizes, the filament physical aspect ratio, and the dispersion of the filament axis around the local magnetic field direction. The abundance and properties of filaments as a function of size determine the slopes of the foreground power spectra, as we show via scaling arguments. The filament aspect ratio determines the ratio of $B$-mode power to $E$-mode power, and specifically reproduces the Planck-observed dust ratio of one-half when the short axis is roughly one-fourth the length of the long axis. Filament misalignment to the local magnetic field determines the $TE$ cross-correlation, and to reproduce Planck measurements, we need a (three-dimensional) misalignment angle with a root mean squared dispersion of about 50 degrees. These parameters are not sensitive to the particular filament density profile. By artificially skewing the distribution of the misalignment angle, this model can reproduce the Planck-observed (and parity-violating) $TB$ correlation. The skewing of the misalignment angle necessary to explain $TB$ will cause a yet-unobserved, positive $EB$ dust correlation, a possible target for future experiments.

description: Based on concepts drawn from the ekpyrotic scenario and M-theory, we elaborate our recent proposal of a cyclic model of the Universe. In this model, the Universe undergoes an endless sequence of cosmic epochs which begin with the Universe expanding from a `big bang' and end with the Universe contracting to a `big crunch.' Matching from `big crunch' to `big bang' is performed according to the prescription recently proposed with Khoury, Ovrut and Seiberg. The expansion part of the cycle includes a period of radiation and matter domination followed by an extended period of cosmic acceleration at low energies. The cosmic acceleration is crucial in establishing the flat and vacuous initial conditions required for ekpyrosis and for removing the entropy, black holes, and other debris produced in the preceding cycle. By restoring the Universe to the same vacuum state before each big crunch, the acceleration insures that the cycle can repeat and that the cyclic solution is an attractor.

description: Ptilotis forresti Ingram
 Ptilotis forresti Ingram, 1906: 116 (Alexandria).
 Now Lichenostomus virescens forresti (Ingram, 1906). See Schodde and Mason, 1999: 234– 235, Christidis and Boles, 2008: 185–191, and Higgins et al., 2008: 598.
 SYNTYPES: AMNH 694789, AMNH 694- 790, adults, collected at Alexandria, 19.00S, 136.42E (Times Atlas), Northern Territory, Australia, in July 1905, by Wilfred Stalker. From the Mathews Collection (nos. 3207 and 3206, respectively) via the Rothschild Collection.
 COMMENTS: No type was designated in the original description, where Ingram said that he had two specimens and that a Gould specimen in BMNH agreed ‘‘fairly well’’ with the two Alexandria specimens. Hartert (1919a: 177) listed as type the specimen, now AMNH 694790, bearing the Rothschild type label and two additional labels. One of the latter is a small tag printed ‘‘MUS. BRIT.’’ and ‘‘SEEBOHM COLL.,’’ both marked out, and bearing the name Ptilotis sonora, with sonora marked out and forresti written in and with ‘‘TYPE’’ written on the reverse. The other label on this specimen is a Mathews Collection label with the place and date of collection filled in and marked ‘‘Type’’ by Mathews. The number ‘‘773’’ on this label refers to the number of this form in Mathews (1908). Despite the fact that this was the specimen that Ingram intended as his type and the specimen Hartert intended to fix as the lectotype, the information given by Hartert (1919a: 177) is ambiguous and applies as well to the second specimen of the type series, now AMNH 694789 (Mathews no. 3207), also collected in July 1905 at Alexandria by Stalker; an AMNH type label has been added to it. The third specimen in the type series is the Gould specimen in BMNH, Reg. no. 1881.5.1.557 5, which Warren and Harrison (1971: 188) listed as a syntype of forresti.
By the time Ingram (1907) reported on the entire collection, he had discovered a third specimen, now AMNH 694791; it has no Mathews catalog number, was not cataloged by Mathews at the same place as the others, and has no date on the original label, only ‘‘Alexandria’’ and ‘‘Stalker.’’ The date of July 05 has been added on the Rothschild label. It was not part of the type series.

Ferromagnetism and its stability from the one-magnon spectrum in twisted bilayer graphene

description: We study ferromagnetism and its stability in twisted bilayer graphene. We work with a Hubbard-like interaction that corresponds to the screened Coulomb interaction in a well-defined limit where the Thomas-Fermi screening length $l_\text{TF}$ is much larger than monolayer graphene's lattice spacing $l_g \ll l_\text{TF}$ and much smaller than the Moiré super lattice's spacing $ l_\text{TF} \ll l_{\text{Moiré}}$. We show that in the perfectly flat band "chiral" limit and at filling fractions $\pm 3/4$, the saturated ferromagnetic (spin and valley polarized) states are ideal ground states candidates in the large band-gap limit. By assuming a large enough substrate (hBN) induced sub-lattice potential, the same argument can be applied to filling fractions $\pm 1/4$. We estimate the regime of stability of the ferromagnetic phase around the chiral limit by studying the exactly calculated spectrum of one-magnon excitations. The instability of the ferromagnetic state is signaled by a negative magnon excitation energy. This approach allows us to deform the results of the idealized chiral model (by increasing the bandwidth and/or modified interactions) towards more realistic systems. Furthermore, we use the low energy part of the exact one-magnon spectrum to calculate the spin-stiffness of the Goldstone modes throughout the ferromagnetic phase. The calculated value of spin-stiffness can determine the excitation energy of charged skyrmions.

description: Magnetization studies have been carried out on superconducting MgB$_2$ (T$_c$=37K) in the temperature range of 2-50K and in magnetic field up to 5 Tesla. From these measurements, values of the lower critical field H$_c1$(0), upper critical field H$_c2$(0) at zero K are estimated to be ~300 Oe and ~12.5 Tesla, respectively, which yield a value of ~26 for the Ginzburg-Landau parameter, k. Magnetization hysteresis loops have been obtained at various temperatures from which the magnetization critical current density is estimated using Bean's critical state model.

description: Im vorliegenden Aufsatz beobachte ich, dass sich die Geschichtsschreibung der Geistes- und Sozialwissenschaften unterscheidet von jener der Naturwissenschaften und schlage eine dreifach gegliederte Typologie dieser spezifischen Entwicklung vor. Im Anschluss frage ich nach den Ursprüngen der genannten Ansätze und untersuche drei Hypothesen: a) die Geistes- und Sozialwissenschaften unterscheiden sich so sehr von den ‚exakten‘ Wissenschaften, dass es unmöglich ist, sie mit Konzepten und Methoden verstehen zu wollen, die aus der Geschichtsschreibung der Naturwissenschaften hervorgegangen sind. b) die Untersuchungsobjekte ändern sich weniger als die Betrachtungsweisen. Nicht unterschiedliche Objekte sondern unterschiedliche Identitäten und Ziele der Historiker/innen bedingen also die abweichenden Geschichtsschreibungen. c) Weder die Untersuchungsobjekte noch die Historiker/innen in den beiden Bereichen differieren voneinander, sondern ihre je spezifische Beziehung zueinander ist ausschlaggebend für die profunden Unterschiede.

 Ptilotis sonora murchisoni Mathews, 1912a: 405 (West Australia (East Murchison)).
 Now Lichenostomus virescens forresti (Ingram, 1906). See Salomonsen, 1967: 375, Schodde and Mason, 1999: 234–235, Christidis and Boles, 2008: 185–191, and Higgins et al., 2008: 598.
 HOLOTYPE: AMNH 694751, adult male, collected at ‘‘ Lake Way,’’ East Murchison, Western Australia, Australia, on 3 July 1909, by F.L. W[hitlock]. From the Mathews Collection (no. 3191) via the Rothschild Collection.
 COMMENTS: Mathews cited his catalog number of the holotype in the original description and gave the range of the form as ‘‘Mid Westralia.’’ There are six paratypes in AMNH, all collected by Whitlock: Borewell, East Murchison, AMNH 694749 (Mathews no. 3195), male, AMNH 694650 (3194), female, 11 August 1909; Lake Way, East Murchison, AMNH 694752 (3192), male, AMNH 694753 (3193), female, 16 July 1909; East Murchison, AMNH 694754 (3916), male, 28 October 1909, AMNH 694755 (3915), female, 4 November 1909.
During the early days of July 1909, Whitlock (1910: 185–186) was collecting around Lake Violet, 26.39S, 120.16E (Johnstone and Storr, 2004: 509), the name given to the northern part of the double lake, the southern part of which is known as Lake Way.

description: It is shown that the desire for smooth and comfortable driving is directly responsible for the occurrence of complex spatio-temporal structures (``synchronized traffic'') in highway traffic. This desire goes beyond the avoidance of accidents which so far has been the main focus of microscopic modeling and which is mainly responsible for the other two phases observed empirically, free flow and wide moving jams. These features have been incorporated into a microscopic model based on stochastic cellular automata and the results of computer simulations are compared with empirical data. The simple structure of the model allows for very fast implementations of realistic networks. The level of agreement with the empirical findings opens new perspectives for reliable traffic forecasts.

A model-independent characterisation of strong gravitational lensing by observables
Creators: name: Wagner, Jenny
Publisher: name: arXiv
Year: 2019
Subjects: subject: Cosmology and Nongalactic Astrophysics (astro-ph.CO)
subject: FOS: Physical sciences

description: When light from a distant source object, like a galaxy or a supernova, travels towards us, it is deflected by massive objects that lie on its path. When the mass density of the deflecting object exceeds a certain threshold, multiple, highly distorted images of the source are observed. This strong gravitational lensing effect has so far been treated as a model-fitting problem. Using the observed multiple images as constraints yields a self-consistent model of the deflecting mass density and the source object. As several models meet the constraints equally well, we develop a lens characterisation that separates data-based information from model assumptions. The observed multiple images allow us to determine local properties of the deflecting mass distribution on any mass scale from one simple set of equations. Their solution is unique and free of model-dependent degeneracies. The reconstruction of source objects can be performed completely model-independently, enabling us to study galaxy evolution without a lens-model bias. Our approach reduces the lens and source description to its data-based evidence that all models agree upon, simplifies an automated treatment of large datasets, and allows for an extrapolation to a global description resembling model-based descriptions.
