description: Using viscoelastic mass/spring model simulations, we explore tidal evolution and migration of compact binary asteroid systems. We find that after the secondary is captured into a spin-synchronous state, non-principal axis rotation in the secondary can be long-lived. The secondary's long axis can remain approximately aligned along the vector connecting secondary to primary while the secondary rocks back and forth about its long axis. Inward orbital semi-major axis migration can also resonantly excite non-principal axis rotation. By estimating solar radiation forces on triangular surface meshes, we show that the magnitude of the BYORP effect induced torque is sensitive to the secondary's spin state. Non-principal axis rotation within the 1:1 spin-orbit resonance can reduce the BYORP torque or cause frequent reversals in its direction.

Can we construct differently from an experience of the degrading environment as function of the discourse of modernity? The answer is yes!

description: The degrading environment is one of the major discussions of our time. The environmental challenges include acid rains, air pollution, global warming, hazardous waste disposal, ozone depletion, smog, water pollution, overpopulation, rainforest destruction, poverty, and soil erosion. The most affected areas include land, forests, water, the ozone layer, people and the biodiversity. It is because of these challenges that climate change is one of the famous discourses of our time. The main argument in this paper is that the degrading environment, as we know it today, is a consequence of the discourse of modernity. The study, however, creates optimism in the environmental rehabilitating processes because as discourses are constructs, instead of constructing destructively, we can construct constructively. In this paper, I begin with the presentation of some re-appraisals on the environmental degradation state. In another section, I present the environmental degradation question as an anthropocentric issue. In a rather long section, I present the environmental degradation as a function of the discourse of modernity. In a final section, I present my own reflection about the environment, beginning from my personal experience to what I think could be done.

description: We determined astrophysical and dynamical parameters of the open clusters (OCs) NGC 2587, Collinder 268 (Col 268), Melotte 72 (Mel 72), and Pismis 7 from Gaia DR2 photometric/astrometric data and a new technique, fitCMD. fitCMD provides (Z, Age(Gyr)) as (0.025, 0.45) for NGC 2587, (0.0025, 0.5) for Col. 268, (0.011, 1.25) for Mel 72, and (0.008, 1.00) for Pismis 7, respectively. As compared to Gaia DR2 distances, the obtained photometric distances from fitCMD provide somewhat close distances. For NGC 2587 and Mel 72, both distances are in good concordance. Except for NGC 2587, the ages of the remaining OCs are higher than their relaxation times, which suggests that they are dynamically relaxed. NGC 2587 did not undergo dynamical evolution. Mel 72 and Pismis 7 with relatively flat MF slopes indicate signs of a somewhat advanced dynamical evolution, in the sense that they appear to have lost a significant fraction of their low-mass stars to the field. Pismis 7's negative/flat MFs indicates that its high mass stars slightly outnumber its low mass ones. Given its mild dynamical evolution, the high mass stars move towards the central region, while low-mass stars are continually being lost to the field. Col 268 presents small dimensions which suggest a primordial origin. The outer parts of Mel 72 and Pismis 7 - with large cluster radii expand with time, while Mel 72's core contracts because of dynamical relaxation (Figs. 10e--f).

Literatur und Politik. Rezeption von Bertolt Brecht in Polen in den Jahren 1948-1953

description: Die Rezeption des literarischen Schaffens eines wie Bertolt Brecht politisch engagierten Autors hängt von einer bestimmten politischen Situation ab. Obwohl Brecht einer der deutschen Schriftsteller der Nachkriegszeit war, deren Werke am frühesten – in den Jahren 1948 und 1949 in Polen veröffentlicht wurden, musste das polnische Publikum viel länger auf die erste Theaterinszenierung seiner Werke warten. Die damalige Kulturpolitik war ein Hindernis. Die Aufführungen des Berliner Ensembles im Jahr 1952 führten zum Anstieg der Popularität von Brechts Werken in Polen, aber auch zu einer Verschärfung der Kulturpolitik durch die polnischen kommunistischen Behörden. Die politische Vereinbarung zwischen der VRP und der DDR hat hierzu einen wesentlichen Beitrag geleistet. Dieser Artikel beschreibt die erste Phase der Rezeption von Bertolt Brechts Werken in Polen in den Jahren 1948‒1953.

description: We present Floquet fractal topological insulators: photonic topological insulators in a fractal-dimensional lattice consisting of helical waveguides. The helical modulation induces an artificial gauge field and leads to the trivial-to-topological transition. The quasienergy spectrum shows the existence of topological edge states corresponding to real-space Chern number 1. We study the propagation of light along the outer edges of the fractal lattice and find that wavepackets move along the edges without penetrating into the bulk or backscattering even in the presence of disorder. In a similar vein, we find that the inner edges of the fractal lattice also exhibit robust transport when the fractal is of sufficiently high generation. Finally, we find topological edge-states that span the circumference of a hybrid half-fractal half-honeycomb lattice, passing from the edge of the honeycomb lattice to the edge of the fractal structure virtually without scattering, despite the transition from two-dimensions to a fractal dimension. Our system offers a realizable experimental platform to study topological fractals and provides new directions for exploring topological physics.

description: Studium dotyczy zjawiska bajronizmu w badaniach Mariana Zdziechowskiego – wybitnego historyka literatury oraz krytyka literackiego żyjącego na przełomie XIX i XX wieków. Uwagę skupiono na analizie dwutomowej monografii Byron i jego wiek. Zdziechowski w rozumieniu definicji bajronizmu wykracza poza swoją epokę, starając się połączyć ten nurt estetyczny z wymiarem etycznym. Jego zdaniem dążenie do doskonałości stanowi istotę romantycznego bajronizmu. Zwrócono też uwagę na odmienności w ocenie nurtu literackiego w poszczególnych krajach Europy Zachodniej i państwach słowiańskich.

description: The focus of our work is to identify conditions for the presence of an isotropic-nematic phase transition in the context of a generic system with isotropic competing interactions. The comment 0709.4205 criticizes our results by showing that the low temperature fluctuations of a stripe phase in 2d diverge linearly in the thermodynamic limit. The analysis is restricted to the stripe phase and does not apply to the central result of our letter. We show, contrary to what is suggested in the comment, that the model introduced by D. G. Barci and D. A. Stariolo in PRL98, 200604 (2007) undergoes an isotropic-nematic phase transition in the Kosterlitz-Thouless universality class.

description: Crossover and mutation are the two main operators that lead to new solutions in evolutionary approaches. In this article, a new method of performing the crossover phase is presented. The problem of choice is evolutionary decision tree construction. The method aims at finding such individuals that together complement each other. Hence we say that they are diversely specialized. We propose the way of calculating the so-called complementary fitness. In several empirical experiments, we evaluate the efficacy of the method proposed in four variants and compare it to a fitness-rank-based approach. One variant emerges clearly as the best approach, whereas the remaining ones are below the baseline.

Struktura romantycznej gawędy szlacheckiej (w jej odmianie żołnierskiej) poddana jest w artykule analizie jako ta dominująca i zarazem jako kompatybilna z przesłaniem afirmacji istnienia, płynącym z pamiętnika. Dzieło Fredry interpretowane jest w kontekście postawy afirmacji w literaturze, psychologii i filozofii. W konkluzji gawęda i jej afirmujący przeszłość charakter zostaje przypisana założeniowi twórczemu komediopisarza, pozostawiającego przyszłym pokoleniom utwór literacki, mający (jak wszystkie gawędy) jeden cel ‒ pamięć o czasach minionych, o tradycjach i obyczajach, i wreszcie ‒ o polskości utraconej na drodze zaborów, chronionej przed zniszczeniem i zapomnieniem przez generacje nieznające w tamtych czasach wolnej Rzeczpospolitej.

description: In biological systems, expression dynamics to shape a fitted phenotype for function has evolved through mutations to genes, as observed in the evolution of funnel landscape in protein. We study this evolutionary process with a statistical-mechanical model of interacting spins, where the fitted phenotype is represented by a configuration of a given set of "target spins" and interaction matrix J among spins is genotype evolving over generations. The expression dynamics is given by stochastic process with temperature T_S to decrease energy for a given set of J. The evolution of J is also stochastic with temperature T_J, following mutation in J and selection based on a fitness given by configurations of the target spins. Below a certain temperature T_S^{c2}, the highly adapted J evolves, whereasanother phase transition characterised by frustration occurs at T_S^{c1}

description: In high-transition temperature (high-Tc) copper oxides, it is generally believed that antiferromagnetism plays a fundamental role in the superconducting mechanism because superconductivity occurs when mobile electrons or holes are doped into the antiferromagnetic parent compounds. The recent discovery of superconductivity in the rare-earth (R) iron-based oxide systems [RO1-xFxFeAs] has generated enormous interest because these materials are the first noncopper oxide superconductors with Tc exceeding 50 K. The parent (nonsuperconducting) LaOFeAs material is metallic but shows anomalies near 150 K in both resistivity and dc magnetic susceptibility. While optical conductivity and theoretical calculations suggest that LaOFeAs exhibits a spin-density-wave (SDW) instability that is suppressed with doping electrons to form superconductivity, there has been no direct evidence of the SDW order. Here we use neutron scattering to demonstrate that LaOFeAs undergoes an abrupt structural distortion below ~150 K, changing the symmetry from tetragonal (space group P4/nmm) to monoclinic (space group P112/n) at low temperatures, and then followed with the development of long range SDW-type antiferromagnetic order at ~134 K with a small moment but simple magnetic structure. Doping the system with flourine suppresses both the magnetic order and structural distortion in favor of superconductivity. Therefore, much like high-Tc copper oxides, the superconducting regime in these Fe-based materials occurs in close proximity to a long-range ordered antiferromagnetic ground state.

description: Let $(W,S)$ be a finite Coxeter system acting by reflections on an $\mathbb R$-Euclidean space with simple roots $Δ=\{\a_s | s\in S\}$ of the same length and fundamental weights $Δ^*=\{v_s | s\in S\}$. We set $M(e)=\sum_{s\in S}κ_s v_s$, $κ_s>0$, and for $w\in W$ we set $M(w)=w(M(e))$. The permutahedron $Perm(W)$ is the convex hull of the set $\{M(w) | w\in W\}$. Given a Coxeter element $c\in W$, we have defined in a previous work a generalized associahedron $Asso_c(W)$ whose normal fan is the corresponding $c$-Cambrian fan $F_c$ defined by N. Reading. By construction, $Asso_c(W)$ is obtained from $Perm(W)$ by removing some halfspaces according to a rule prescribed by $c$. In this work, we classify the isometry classes of these realizations. More precisely, for $(W,S)$ an irreducible finite Coxeter system and $c,c'$ two Coxeter elements in $W$, we have that $Asso_{c}(W)$ and $Asso_{c'}(W)$ are isometric if and only if $μ(c') = c$ or $μ(c')=w_0c^{-1}w_0$ for $μ$ an automorphism of the Coxeter graph of $W$ such that $κ_s=κ_{μ(s)}$ for all $s\in S$. As a byproduct, we classify the isometric Cambrian fans of $W$.

Large perturbative logarithms in the hard-scattering kernels are identified and resummed using soft-collinear effective theory. We use our results to estimate the branching fractions for $B\to K^*γ$ and $B_s\to ϕγ$ decays at NNLO and compare them with the current experimental data.

description: We estimate the effect of the experimental uncertainty in the measurement of the temperature of the cosmic microwave background (CMB) on the extraction of cosmological parameters from future CMB surveys. We find that even for an ideal experiment limited only by cosmic variance up to l = 2500 for both the temperature and polarisation measurements, the projected cosmological parameter errors are remarkably robust against the uncertainty of 1 mK in the FIRAS instrument's CMB temperature monopole measurement. The maximum degradation in sensitivity is 20%, for the baryon density estimate, relative to the case in which the monopole is known infinitely well. While this degradation is acceptable, we note that reducing the uncertainty in the current temperature measurement by a factor of five will bring it down to the per cent level. We also estimate the effect of the uncertainty in the dipole temperature measurement. Assuming the overall calibration of the data to be dominated by the dipole error of 0.2% from FIRAS, the sensitivity degradation is insignificant and does not exceed 10% in any parameter direction.

Measurement of the Lamb shift in muonium
Creators: name: Fry, Charles Alan
Publisher: name: University of British Columbia
Year: 2010

description: This thesis describes the first measurement of the Lamb shift in n=2 muonium. The muonium atom is a hydrogen-like bound state of two leptons (µ⁺e⁻), both of which are believed to be point-like particles. The point-like nature of the constituent particles simplifies and reduces the uncertainty of the application of quantum electrodynamics (QED) to the calculation of the Lamb shift in the muonium atom. Measurements of the Lamb shift in hydrogen disagree with the predictions of theory by a few standard deviations; however, theoretical predictions also disagree with each other, partly because of difficulties associated with the treatment of the proton structure. Thus a measurement in the muonium system of similar precision to those already made in the hydrogen system will be a valuable test of QED. The present experiment is not intended to test QED. It is an investigation of the methods and techniques necessary to surmount the difficulties presented by the nature of muonium. The available number of muonium atoms is about 10⁺¹º times less than that of hydrogen used by Lamb in his first measurement. The value obtained for the n=2 muonium Lamb shift 1070⁺¹²₋₁₅ MHz. The uncertainty quoted is statistical at the 68% confidence level. Systematic effects were found to contribute to a further 2 MHz uncertainty.

description: NGC 205, a close satellite of the M31 galaxy, is our nearest example of a dwarf elliptical galaxy. Photometric and kinematic observations suggest that NGC 205 is undergoing tidal distortion from its interaction with M31. Despite earlier attempts, the orbit and progenitor properties of NGC 205 are not well known. We perform an optimized search for these unknowns by combining a genetic algorithm with restricted N-body simulations of the interaction. This approach, coupled with photometric and kinematic observations as constraints, allows for an effective exploration of the parameter space. We represent NGC 205 as a static Hernquist potential with embedded massless test particles that serve as tracers of surface brightness. We explore 3 distinct, initially stable configurations of test particles: cold rotating disk, warm rotating disk, and hot, pressure-supported spheroid. Each model reproduces some, but not all, of the observed features of NGC 205, leading us to speculate that a rotating progenitor with substantial pressure support could match all of the observables. Furthermore, plausible combinations of mass and scale length for the pressure-supported spheroid progenitor model reproduce the observed velocity dispersion profile. For all 3 models, orbits that best match the observables place the satellite 11+/-9 kpc behind M31 moving at very large velocities: 300-500 km/s on primarily radial orbits. Given that the observed radial component is only 54 km/s, this implies a large tangential motion for NGC 205, moving from the NW to the SE. These results suggest NGC 205 is not associated with the stellar arc observed to the NE of NGC 205. Furthermore, NGC 205's velocity appears to be near or greater than its escape velocity, signifying that the satellite is likely on its first M31 passage.

Electron Clusters in Inert Gases

Subjects: subject: Atomic and Molecular Clusters (physics.atm-clus)

description: The paper addresses counterintuitive behavior of electrons injected into dense cryogenic media with negative scattering length $a_0$. Instead of expected polaronic effect (formation of density enhancement clusters) which should substantially reduce the electron mobility, an opposite picture is observed: with increasing $|a_0|$ (the trend taking place for inert gases with the growth of atomic number) and the medium density, the electrons remain practically free. An explanation of this behaviour is provided based on consistent accounting for the non-linearity of electron interaction with the gaseous medium in the gas atom number density.
Fermi-Fermi Mixtures in the Strong Attraction Limit

description: The phase diagrams of low density Fermi-Fermi mixtures with equal or unequal masses and equal or unequal populations are described at zero and finite temperatures in the strong attraction limit. In this limit, the Fermi-Fermi mixture can be described by a weakly interacting Bose-Fermi mixture, where the bosons correspond to Feshbach molecules and the fermions correspond to excess atoms. First, we discuss the three and four fermion scattering processes, and use the exact boson-fermion and boson-boson scattering lengths to generate the phase diagrams in terms of the underlying fermion-fermion scattering length. In three dimensions, in addition to the normal and uniform superfluid phases, we find two stable non-uniform states corresponding to (1) phase separation between pure unpaired (excess) and pure paired fermions (molecular bosons); and (2) phase separation between pure excess fermions and a mixture of excess fermions and molecular bosons. Lastly, we also discuss the effects of the trapping potential in the density profiles of condensed and non-condensed molecular bosons, and excess fermions at zero and finite temperatures, and discuss possible implications of our findings to experiments involving mixtures of ultracold fermions.

description: We consider the problem of coarse-graining in the context of finite-volume fluid models. If a variable is defined on a high-resolution grid it may be coarse-grained so that it is defined on a grid of lower resolution. In general this will cause some information about the variable to be lost. In particular, horizontal divergences, gradients or other operators calculated on the coarse grid after projecting may differ from those calculated on the fine grid. In some cases we are able to choose averaging weights for coarse-graining such that the coarse-grid operators will give a result approximating that of the corresponding fine-grid operators applied on the fine grid. In this work we derive general conditions on the averaging weights that allow the divergence and gradient to be preserved. These conditions are applied to a regular triangular mesh with B-grid variable placement in which the fine-grid resolution is some integer multiple $N$ of the coarse-grid resolution. For this case we find particular values for the averaging weights that preserve the divergence, and a set of different averaging weights that preserve the gradient. We observe that the vertical component of the curl is also preserved by the same coarse-graining that preserves divergence. These coarse-grainings are applied to data from FESOM2 simulations and we demonstrate that using the particular coarse-grainings derived herein gives an overall reduction in $L^1$ error when compared with other methods.

description: Sakrament małżeństwa w samej swej nazwie ma proweniencję religijną, jakkolwiek łączy w sobie także sferę profanum – wszystko co ludzkie, codzienne, prozaiczne. W niniejszym artykule podjęto próbę rekonstrukcji składników językowego obrazu góralskiego małżeństwa i roli miłości w podejmowaniu decyzji o założeniu rodziny. Korzystając z założeń metodologicznych JOS, analizie poddano teksty napisane w gwarze podhalańskiej. Na tej podstawie scharakteryzowano małżeństwo jako wynik konwencji społecznej, na mocy której w pary łączyli się ludzie o podobnym statusie majątkowym. Subtelne i czułe relacje towarzyszące zakochaniu oraz małżeńskie sacrum były zdeterminowane przez trudną sytuację życiową. Ślub nie był więc związkiem serc, tylko pragmatyczną decyzją, której celem było zapewnienie godnego bytu nowo powstałej rodzinie.

description: Students will first introduce themselves and set up group norms. The first part of the activity will ask them to address their ideas about where antibiotic resistance comes from. This will be done through a Google form and question of the whole group.

Next, students will engage with the activity through watching short videos and interpreting infographics together. These videos and infographics were chosen because they help tease apart some of the specific misconceptions.

Finally, students will discuss their overall conclusions about where antibiotic resistance comes from (aka…it evolves!) and write their final thoughts on the slide. They will also answer the questions on the Google form with their updated understanding.
Locking of skyrmion cores on a centrosymmetric discrete lattice: onsite versus offsite

description: A magnetic skyrmion crystal (SkX) with a swirling spin configuration, which is one of topological spin crystals as a consequence of an interference between multiple spin density waves, shows a variety of noncoplanar spin patterns depending on a way of superposing the waves. By focusing on a phase degree of freedom among the constituent waves in the SkX, we theoretically investigate a position of the skyrmion core on a discrete lattice, which is relevant with the symmetry of the SkX. The results are obtained for the double exchange (classical Kondo lattice) model on a discrete triangular lattice by the variational calculations. We find that the skyrmion cores in both two SkXs with the skyrmion number of one and two are locked at the interstitial site on the triangular lattice, while it is located at the onsite by introducing a relatively large easy-axis single-ion anisotropy. The variational parameters and the resultant Fermi surfaces in each SkX spin texture are also discussed. The different symmetry of the Fermi surfaces depending on the core position is obtained when the skyrmion crystal is commensurate with the lattice. The different Fermi-surface topology is directly distinguished by an electric probe of angle-resolved photoemission spectroscopy. Furthermore, we show that the SkXs obtained by the variational calculations are also confirmed by numerical simulations on the basis of the kernel polynomial method and the Langevin dynamics for the double exchange model and the simulated annealing for an effective spin model.

Emotions and the Problem of Variability

Publisher: name: Humboldt-Universität zu Berlin
Year: 2020
Subjects: subject: 100 Philosophie

description: In the last decades there has been a great controversy about the scientific status of emotion categories. This controversy stems from the idea that emotions are heterogeneous phenomena, which precludes classifying them under a common kind. In this article, I analyze this claim—which I call the Variability Thesis—and argue that as it stands, it is problematically underdefined. To show this, I examine a recent formulation of the thesis as offered by Scarantino (2015). On one hand, I raise some issues regarding the logical structure of the claim. On the other hand, and most importantly, I show that the Variability Thesis requires a consensus about what counts as a relevant pattern of response in different domains, a consensus that is lacking in the current literature. This makes it difficult to assess what counts as evidence for or against this thesis. As a result, arguments based on the Variability Thesis are unwarranted. This raises serious concerns about some current empirical theories of emotions, but also sheds light on the issue of the scientific status of emotion categories.

description: Colloidal rods immersed in a thermotropic liquid-crystalline solvent are at the basis of so-called hybrid liquid crystals which are characterized by tunable nematic fluidity with symmetries ranging from conventional uniaxial nematic or anti-nematic to orthorhombic [Mundoor et al., Science 360, 768 (2018)]. We provide a theoretical analysis of the elastic moduli of such systems by considering interactions between the individual rods with the embedding solvent through surface-anchoring forces, as well as steric and electrostatic interactions between the rods themselves. For uniaxial systems the presence of colloidal rods generates a marked increase of the splay elasticity which we found to be in quantitative agreement with experimental measurements. For orthorhombic hybrid liquid crystals we provide estimates of all twelve elastic moduli and show that only a small subset of those elastic constants play a relevant role in describing the nemato-elastic properties. The complexity and possibilities related to identifying the elastic moduli in experiments are briefly discussed. The results are expected to be helpful in stimulating future studies on defect-dressed "topological" colloids and the analysis of boundary-driven phenomena where the non-trivial director topology generated by biaxial nematics plays a key role.
