description: We use the SU(2) 't Hooft-Polyakov monopole configuration, and its BPS version, to test the integral equations of the Yang-Mills theory. Those integral equations involve two (complex) parameters which do not appear in the differential Yang-Mills equations, and if they are considered to be arbitrary it then implies that non-abelian gauge theories (but not abelian ones) possess an infinity of integral equations. For static monopole configurations only one of those parameters is relevant. We expand the integral Yang-Mills equation in a power series of that parameter and show that the 't Hooft-Polyakov monopole and its BPS version satisfy the integral equations obtained in first and second order of that expansion. Our results points to the importance of exploring the physical consequences of such an infinity of integral equations on the global properties of the Yang-Mills theory.

description: We study galaxy shapes in the Illustris cosmological hydrodynamic simulation. We find that massive galaxies have a higher probability of being prolate. For galaxies with stellar mass larger than $10^{11}\rm M_{\odot}$, 35 out of total 839 galaxies are prolate. For 21 galaxies with stellar mass larger than $10^{12}\rm M_{\odot}$, 9 are prolate, 4 are triaxial while the others are close to being oblate. There are almost no prolate galaxies with stellar mass smaller than $3\times10^{11}\rm M_{\odot}$. We check the merger history of the prolate galaxies, and find that they are formed by major dry mergers. All the prolate galaxies have at least one such merger, with most having mass ratios between $1:1$ and $1:3$. The gas fraction (gas mass to total baryon mass) of the progenitors is 0-3 percent for nearly all these mergers, except for one whose second progenitor contains $\sim 15\%$ gas mass, while its main progenitor still contains less than $5\%$. For the 35 massive prolate galaxies that we find, 18 of them have minor axis rotation, and their angular momenta mostly come from the spin angular momenta of the progenitors (usually that of the main progenitor). We analyse the merger orbits of these prolate galaxies and find that most of them experienced a nearly radial merger orbit. Oblate galaxies with major dry mergers can have either radial or circular merger orbits. We further discuss various properties of these prolate galaxies, such as spin parameter $λ_{\rm R}$, spherical anisotropy parameter $β$, dark matter fraction, as well as inner density slopes for the stellar, dark matter and total mass distributions.

description: One-dimensional chain of pointwise particles harmonically coupled with nearest neighbors and placed in six-order polynomial on-site potentials is considered. Power of the energy source in the form of single ac driven particles is calculated numerically for different amplitudes $A$ and frequencies $ω$ within the linear phonon band. The results for the on-site potentials with hard and soft nonlinearity types are compared. For the hard-type nonlinearity, it is shown that when the driving frequency is close to (far from) the {\em upper} edge of the phonon band, the power of the energy source normalized to $A^2$ increases (decreases) with increasing $A$. In contrast, for the soft-type nonlinearity, the normalized power of the energy source increases (decreases) with increasing $A$ when the driving frequency is close to (far from) the {\em lower} edge of the phonon band. Our further demonstrations indicate that, in the case of hard (soft) anharmonicity, the chain can support movable discrete breathers (DBs) with frequencies above (below) the phonon band. It is the energy source quasi-periodically emitting moving DBs in the regime with driving frequency close to the DBs frequency, that induces the increase of the power. Therefore, our results here support the mechanism that the moving DBs can assist energy transfer from the ac driven particle to the chain.

Chaotic orbits obeying one isolating integral in a four dimensional map

description: We have recently presented strong evidence that chaotic orbits that obey one isolating integral besides energy exist in a toy Hamiltonian model with three degrees of freedom and are bounded by regular orbits that isolate them from the Arnold web. The interval covered by those numerical experiments was equivalent to about one million Hubble times in a galactic context. Here we use a four dimensional map to confirm our previous results and to extend that interval fifty times. We show that, at least within that interval, features found in lower dimension Hamiltonian systems and maps are also present in our study, e.g., within the phase space occupied by a chaotic orbit that obeys one integral there are subspaces where that orbit does not enter and are, instead, occupied by regular orbits that, if tori, bound other chaotic orbits obeying one integral and, if cantori, produce stickiness. We argue that the validity of our results might exceed the time intervals covered by the numerical experiments.

description: We consider a six dimensional space-time, in which two of the dimensions are compactified by a flux. Matter can be localized on a codimension one brane coupled to the bulk gauge field and wrapped around an axis of symmetry of the internal space. By studying the linear perturbations around this background, we show that the gravitational interaction between sources on the brane is described by Einstein 4d gravity at large distances. Our model provides a consistent setup for the study of gravity in the rugby (or football) compactification, without having to deal with the complications of a delta-like, codimension two brane. To our knowledge, this is the first complete study of gravity in a realistic brane model with two extra dimensions, in which the mechanism of stabilization of the extra space is consistently taken into account.

Comparison of damping mechanisms for transverse waves in solar coronal loops

Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)

description: We present a method to assess the plausibility of alternative mechanisms to explain the damping of magnetohydrodynamic (MHD) transverse waves in solar coronal loops. The considered mechanisms are resonant absorption of kink waves in the Alfvén continuum, phase-mixing of Alfvén waves, and wave leakage. Our methods make use of Bayesian inference and model comparison techniques. We first infer the values for the physical parameters that control the wave damping, under the assumption of a particular mechanism, for typically observed damping time-scales. Then, the computation of marginal likelihoods and Bayes factors enable us to quantify the relative plausibility between the alternative mechanisms. We find that, in general, the evidence is not large enough to support a single particular damping mechanism as the most plausible one. Resonant absorption and wave leakage offer the most probable explanations in strong damping regimes, while phase mixing is the best candidate for weak/moderate damping. When applied to a selection of 89 observed transverse loop oscillations, with their corresponding measurements of damping times scales and taking into account data uncertainties, we find that only in a few cases positive evidence for a given damping mechanism is available.

description: The interest in historical floristic data has been increasing during recent years because of their potential to give insight covering historical periods for which few other data are available. The recent discovery of a historical flora referred to an area of Sardinia (Italy) named Sassarese, for which a relatively updated flora was known, was an opportunity to verify the potentiality of historical data and to provide information for interpreting biodiversity history identifying possible shifts in the flora related to land use changes. Comparing the two floras, we found that 60% of segetal/crop relative species and 20% of freshwater habitat species disappeared and that the introduction of seven alien species has to be dated back. The trends detected may be helpful for future management choices, which should consider the possibility of recovering habitats and activities that encourage the return of disappeared species, perhaps even thinking about restoration projects.

description: We develop a formalism for calculating the distribution of the axial quadrupole operator in the laboratory frame within the rotationally invariant framework of the configuration-interaction shell model. The calculation is carried out using a finite-temperature auxiliary-field quantum Monte Carlo method. We apply this formalism to isotope chains of even-mass samarium and neodymium nuclei, and show that the quadrupole distribution provides a model-independent signature of nuclear deformation. Two technical advances are described that greatly facilitate the calculations. The first is to exploit the rotational invariance of the underlying Hamiltonian to reduce the statistical fluctuations in the Monte Carlo calculations. The second is to determine quadruple invariants from the distribution of the axial quadrupole operator. This allows us to extract effective values of the intrinsic quadrupole shape parameters without invoking an intrinsic frame or a mean-field approximation.

description: Retinal ganglion cell axons are heavily myelinated (98%) and myelin damage in the optic nerve (ON) severely affects vision. Understanding the molecular mechanism of oligodendrocyte progenitor cell (OPC) differentiation into mature oligodendrocytes will be essential for developing new therapeutic approaches for ON demyelinating diseases. To this end, we developed a new method for isolation and culture of ON-derived oligodendrocyte lineage cells and used it to study OPC differentiation. A critical aspect of cellular differentiation is macroautophagy/autophagy, a catabolic process that allows for cell remodeling by degradation of excess or damaged cellular molecules and organelles. Knockdown of ATG9A and BECN1 (pro-autophagic proteins involved in the early stages of autophagosome formation) led to a significant reduction in proliferation and survival of OPCs. We also found that autophagy flux (a measure of autophagic degradation activity) is significantly increased during progression of oligodendrocyte differentiation. Additionally, we demonstrate a significant change in mitochondrial dynamics during oligodendrocyte differentiation, which is associated with a significant increase in programmed mitophagy (selective autophagic clearance of mitochondria). This process is mediated by the mitophagy receptor BNIP3L (BCL2/adenovirus E1B interacting protein 3-like). BNIP3L-mediated mitophagy plays a crucial role in the regulation of mitochondrial network formation, mitochondrial function and the viability of newly differentiated oligodendrocytes. Our studies provide novel evidence that proper mitochondrial dynamics is required for establishment of functional mitochondria in mature oligodendrocytes. These findings are significant because targeting BNIP3L-mediated programmed mitophagy may provide a novel therapeutic approach for stimulating myelin repair in ON demyelinating diseases.

This approach includes the local correlations of dynamical mean field theory and long-range correlations beyond. It allows for example to describe (para-)magnons and weak localization effects in strongly correlated systems. As a first application, we study the interplay between nonlocal antiferromagnetic correlations and the strong local correlations emerging in the vicinity of a Mott-Hubbard transition.

The Effect of Judicial Independence on Courts: Evidence from the American States

description: This paper provides new evidence on the relationship between judicial independence and the quality of state courts. The paper examines two state-level factors that affect judicial independence: i) state judicial retention policies and ii) stability of the state constitution. The paper shows that these two factors are largely determined by a combination of statelevel initial conditions and lagged state-level political variables. Using initial conditions and lagged political variables as instruments, the paper finds that increasing judicial independence by changing judicial retention policy away from partisan elections would increase the quality of state courts by roughly one and a half standard deviations. Similarly, increasing independence by decreasing the state constitution amendment rate from the 75th percentile to the 25th percentile would increase the quality of courts by roughly three quarters of a standard deviation.

description: We use the covariant current formalism to derive the general form of the 2-photon correlation function for fully chaotic sources. Motivated by the recent discussion in the literature we concentrate on the effects from the photon spin on the correlator. We show that for locally thermalized expanding sources, like those expected to be created in relativistic heavy ion collisions, the only change relative to 2-pion interferometry is a statistical factor 1/2 for the overall strength of the correlation which results from the experimental averaging over the photon spin.

description: We extend the ordinary 3D electromagnetic duality to the noncommutative (NC) space-time through a Seiberg-Witten map to second order in the noncommutativity parameter (theta), defining a new scalar field model. There are similarities with the 4D NC duality, these are exploited to clarify properties of both cases. Up to second order in theta, we find that duality interchanges the 2-form theta with its 1-form Hodge dual *theta times the gauge coupling constant, i.e., theta --> *theta g^2 (similar to the 4D NC electromagnetic duality). We directly prove that this property is false in the third order expansion in both 3D and 4D space-times, unless the slowly varying fields limit is imposed. Outside this limit, starting from the third order expansion, theta cannot be rescaled to attain an S-duality. In addition to possible applications on effective models, the 3D space-time is useful for studying general properties of NC theories. In particular, in this dimension, we deduce an expression that significantly simplifies the Seiberg-Witten mapped Lagrangian to all orders in theta.

General considerations on the illumination of galactic nebulae

Publisher: name: arXiv
Year: 2000
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: The interpretation of observations over different wavelength domains, which now exist over a large fraction of the sky, will be used to determine relationships between a nebula and its' illuminating source. The illuminating source of a high latitude nebula must be behind the cloud and e.g. at close angular distance. It is either a point source behind the nebula or the average radiation field created by all the background stars. In the latter case it is possible to estimate the maximum surface brightness a nebula can reach. Illumination by the galactic plane is always negligible in up to date observations. The red color of some nebulae, when they are not HII regions, is more likely to be due to large column densities than to an emission process. Concerning interstellar grain properties, the same data will be used to support the well known property that grains scatter starlight in forward direction.

 CURRENT STATUS: junior synonym of Thelaira nigripes (Fabricius, 1794) (Herting & Dely-Draskovits 1993: 390).
 REMARKS: Rondani (1862d: 175) proposed Telaira intuenda for Thelaira nigripes (Fabricius, 1794) sensu Walker (1853: 96), which he considered a new species. Rondani referred to Walker’s redescription of Telaira nigripes, which was based on an unspecified number of specimens, and to an unspecified number of specimens of both sexes he had collected and also received from G. Passerini: “ Semel marem … legi, … Foeminas paucas … observavi [once I collected the male, … I observed a few females]”. Therefore, the type material should be in the collections of Walker (NHMUK) and Rondani. We found five syntypes under the name Telaira intuenda in this study. No specimen under the name Telaira nigripes is present in the NHMUK (N. Wyatt, pers. comm., September 2019). Rondani described this nominal species under the generic name Telaira, which is an “unjustified emendation of Thelaira Robineau-Desvoidy, 1830 ” (O’Hara et al. 2011: 176).

description: Excerpts from the report: Over the last decade or so, egg production has not kept pace with population growth mainly because the demand for eggs has been declining. At the same time, egg production has been limited because of relatively more attractive economic opportunities for people in other lines of agriculture and in nonfarm pursuits. The 24 percent increase in population between 1947-49 and 1961 has been accompanied by only an 11 percent rise in farm egg output, despite declining prices for eggs and rising per capita incomes. All regions did not share equally in the larger egg production. Output expanded at several times the national rate in the South Atlantic and Western regions and declined significantly in the North Central Region. These changes brought about a substantial shift in the regional distribution of egg production in the United States.

description: Objectives This paper uses a sample of convicted offenders from Pennsylvania to estimate the effect of incarceration on post-release criminality. Methods To do so, we capitalize on a feature of the criminal justice system in Pennsylvania—the county-level randomization of cases to judges. We begin by identifying five counties in which there is substantial variation across judges in the uses of incarceration, but no evidence indicating that the randomization process had failed. The estimated effect of incarceration on rearrest is based on comparison of the rearrest rates of the caseloads of judges with different proclivities for the use of incarceration. Results Using judge as an instrumental variable, we estimate a series of confidence intervals for the effect of incarceration on one year, two year, five year, and ten year rearrest rates. Conclusions On the whole, there is little evidence in our data that incarceration impacts rearrest.

description: The entropic force exerted by the Brownian fluctuations of a grafted semiflexible polymer upon a rigid smooth wall are calculated both analytically and by Monte Carlo simulations. Such forces are thought to play an important role for several cellular phenomena, in particular, the physics of actin-polymerization-driven cell motility and movement of bacteria like Listeria. In the stiff limit, where the persistence length of the polymer is larger than its contour length, we find that the entropic force shows scaling behavior. We identify the characteristic length scales and the explicit form of the scaling functions. In certain asymptotic regimes we give simple analytical expressions which describe the full results to a very high numerical accuracy. Depending on the constraints imposed on the transverse fluctuations of the filament there are characteristic differences in the functional form of the entropic forces; in a two-dimensional geometry the entropic force exhibits a marked peak.

description: Digital piracy is a significant problem for the creative industries. Still, while there have been many academic studies showing that piracy hurts sales, there have been far fewer studies analyzing the effectiveness of anti-piracy measures in reversing this effect. This study attempts to address this question by analyzing how the HADOPI “three strikes” law in France affected digital music sales on the iTunes music store.

To do this, we obtained a panel of iTunes sales data from the four major music labels (Universal Music, Warner Music, EMI Music and Sony Music) across a broad set of countries. We then applied a difference-in-difference approach, using sales trends in a control group of European countries to simulate the counterfactual of what music sales in France would have been if HADOPI had not been passed. Our results suggest that increased consumer awareness of HADOPI caused iTunes song and album sales to increase by 22.5% and 25% respectively relative to changes in the control group.

In terms of robustness, we find that these sales changes are similar for each of the four major music labels, suggesting that our results are not peculiar to any particular label. We also find that the observed sales increase is much larger in genres that, prior to HADOPI, experienced high piracy levels (e.g., Rap and Hip Hop) than for less pirated genres (e.g., Christian music, classical, and jazz). This strengthens the causal interpretation of our results since if HADOPI is causing pirates to become legitimate purchases, its effects should be stronger for heavily pirated music than it is for other music genres.

description: Combining targeted therapeutic agents is an attractive cancer treatment strategy associated with high efficacy and low toxicity. DNA-dependent protein kinase catalytic subunit (DNA-PKcs) is an essential factor in DNA damage repair. Studies from us and others have revealed that DNA-PKcs also plays an important role in normal mitosis progression. Histone deacetylase (HDACs) inhibitors commonly lead to mitotic aberration and have been approved for treating various cancers in the clinic. We showed that DNA-PKcs depletion or kinase activity inhibition increases cancer cells’ sensitivity to HDACs inhibitors in vitro and in vivo. DNA-PKcs deficiency significantly enhances HDACs inhibitors (HDACi)-induced mitotic arrest and is followed by apoptotic cell death. Mechanistically, we found that DNA-PKcs binds to HDAC6 and facilitates its acetylase activity. HDACi is more likely to impair HDAC6-induced deacetylation of HSP90 and abrogate HSP90’s chaperone function on Aurora A, a critical mitotic kinase that regulates centrosome separation and mitotic spindle assembly in DNA-PKcs-deficient cells. Our current work indicates crosstalk between DNA-PKcs and HDACs signaling pathways, and highlights that the combined targeting of DNA-PKcs and HDACs can be used in cancer therapy.

Remark on the effective potential of the gravitational perturbation in the black hole background projected on the brane

description: The polar perturbation is examined when the spacetime is expressed by a 4d metric induced from higher-dimensional Schwarzschild geometry. Since the spacetime background is not a vacuum solution of 4d Einstein equation, the various general principles are used to understand the behavior of the energy-momentum tensor under the perturbation. It is found that although the general principles fix many components, they cannot fix two components of the energy-momentum tensor. Choosing two components suitably, we derive the effective potential which has a correct 4d limit.

description: We perform Landau-Zener-Stuckelberg-Majorana (LZSM) spectroscopy on a system with strong spin-orbit interaction (SOI), realized as a single hole confined in a gated double quantum dot. In analogy to the electron systems, at magnetic field B=0 and high modulation frequencies we observe the photon-assisted tunneling (PAT) between dots, which smoothly evolves into the typical LZSM funnel-shaped interference pattern as the frequency is decreased. In contrast to electrons, the SOI enables an additional, efficient spin-flipping interdot tunneling channel, introducing a distinct interference pattern at finite B. Magneto-transport spectra at low-frequency LZSM driving show the two channels to be equally coherent. High-frequency LZSM driving reveals complex photon-assisted tunneling pathways, both spin-conserving and spin-flipping, which form closed loops at critical magnetic fields. In one such loop an arbitrary hole spin state is inverted, opening the way toward its all-electrical manipulation.

description: Imprinting of cholesteric textures in a polymer network is a method of preserving a macroscopically chiral phase in a system with no molecular chirality. By modifying the elastics properties of the network, the resulting stored helical twist can be manipulated within a wide range since the imprinting efficiency depends on the balance between the elastics constants and twisting power at network formation. One spectacular property of phase chirality imprinting is the created ability of the network to adsorb preferentially one stereo-component from a racemic mixture. In this paper we explore this property of chirality transfer from a macroscopic to the molecular scale. In particular, we focus on the competition between the phase chirality and the local nematic order. We demonstrate that it is possible to control the subsequent release of chiral solvent component from the imprinting network and the reversibility of the stereo-selective swelling by racemic solvents.

description: In this contribution, Godfrey highlights the importance of the digital revolution in expanding access to historical documents. Through projects such as the Digital Panopticon, digitisation has not only aided academic research but also enabled citizen investigation. Using a number of life history examples, the author illustrates the value of data democratisation, but also warns of issues that arise when autobiographies contradict official records. Godfrey ends by noting that, whilst invaluable – particularly given the closure of physical archives during the pandemic – digital archives should be an addition, not a substitute, for archival study.

description: We report on the observation of gate-tunable proximity-induced superconductivity and multiple Andreev reflections (MAR) in a bulk-insulating BiSbTeSe$_2$ topological insulator nanoribbon (TINR) Josephson junction (JJ) with superconducting Nb contacts. We observe a gate-tunable critical current ($I_C$) for gate voltages ($V_g$) above the charge neutrality point ($V_{CNP}$), with $I_C$ as large as 430 nA. We also observe MAR peaks in the differential conductance ($dI/dV$) versus DC voltage ($V_{dc}$) across the junction corresponding to sub-harmonic peaks (at $V_{dc} = V_n = 2Δ_{Nb}/en$, where $Δ_{Nb}$ is the superconducting gap of the Nb contacts and $n$ is the sub-harmonic order). The sub-harmonic order, $n$, exhibits a $V_g$-dependence and reaches $n = 13$ for $V_g = 40$ V, indicating the high transparency of the Nb contacts to TINR. Our observations pave the way toward exploring the possibilities of using TINR in topologically protected devices that may host exotic physics such as Majorana fermions.
Meson and Quark Degrees of Freedom and the Radius of the Deuteron

description: The existing experimental data for the deuteron charge radius are discussed. The data of elastic electron scattering are inconsistent with the value obtained in a recent atomic physics experiment. Theoretical predictions based on a nonrelativistic description of the deuteron with realistic nucleon-nucleon potentials and with a rather complete set of meson-exchange contributions to the charge operator are presented. Corrections arising from the quark-gluon substructure of the nucleon are explored in a nonrelativistic quark model; the quark-gluon corrections, not accounted for by meson exchange, are small. Our prediction for the deuteron charge radius favors the value of a recent atomic physics experiment.

 CURRENT STATUS: junior synonym of Exorista (Podotachina) grandis (Zetterstedt, 1844) (Herting & Dely-Draskovits 1993: 123).
 REMARKS: Rondani (1859b: 185) described both sexes of Thricolyga major, without specifying the exact number of male specimens and not giving a range of lengths: “ Mares non frequenter legi … foeminam unicam [I infrequently collected males … I saw a single female]” he had collected and also received from S. Bertolini. We found six syntypes in this study. Rondani described this nominal species under the generic name “ Thricolyga ”, which is an “incorrect original spelling of Tricoliga Rondani, 1856 ” (O’Hara et al. 2011: 179).
