description: We report on a search for gravitational waves from the coalescence of compact binaries during the third and fourth LIGO science runs. The search focused on gravitational waves generated during the inspiral phase of the binary evolution. In our analysis, we considered three categories of compact binary systems, ordered by mass: (i) primordial black hole binaries with masses in the range 0.35 M(sun) < m1, m2 < 1.0 M(sun), (ii) binary neutron stars with masses in the range 1.0 M(sun) < m1, m2 < 3.0 M(sun), and (iii) binary black holes with masses in the range 3.0 M(sun)< m1, m2 < m_(max) with the additional constraint m1+ m2 < m_(max), where m_(max) was set to 40.0 M(sun) and 80.0 M(sun) in the third and fourth science runs, respectively. Although the detectors could probe to distances as far as tens of Mpc, no gravitational-wave signals were identified in the 1364 hours of data we analyzed. Assuming a binary population with a Gaussian distribution around 0.75-0.75 M(sun), 1.4-1.4 M(sun), and 5.0-5.0 M(sun), we derived 90%-confidence upper limit rates of 4.9 yr^(-1) L10^(-1) for primordial black hole binaries, 1.2 yr^(-1) L10^(-1) for binary neutron stars, and 0.5 yr^(-1) L10^(-1) for stellar mass binary black holes, where L10 is 10^(10) times the blue light luminosity of the Sun.

description: There is evidence for the existence of massive planets at orbital radii of several hundred AU from their parent stars where the timescale for planet formation by core accretion is longer than the disc lifetime. These planets could have formed close to their star and then migrated outwards. We consider how the transfer of angular momentum by viscous disc interactions from a massive inner planet could cause significant outward migration of a smaller outer planet. We find that it is in principle possible for planets to migrate to large radii. We note, however, a number of effects which may render the process somewhat problematic.

CURRENT STATUS: valid species (Pont 1986b: 63).
REMARKS: Rondani (1866a: 135) proposed Azelia zetterstedtii for Aricia triquetra (Wiedemann, 1817) sensu Zetterstedt (1845: 1590), which he considered a new species. Rondani referred to Zetterstedt’s redescription of Azelia triquetra, which was based on an unspecified number of specimens, and to a single specimen received from Mr. Staeger. Therefore, the type material is in the collections of Zetterstedt (MZLU) and Rondani (MZUF). We found 13 syntypes in this study.

description: We present X-ray, broad band optical and low frequency radio observations of the bright type IIP supernova SN 2004et. The \cxo observed the supernova at three epochs, and the optical coverage spans a period of $\sim$ 470 days since explosion. The X-ray emission softens with time, and we characterise the X-ray luminosity evolution as $\Lx \propto t^{-0.4}$. We use the observed X-ray luminosity to estimate a mass-loss rate for the progenitor star of $\sim \ee{2}{-6} M_\odot \mathrm{yr}^{-1}$. The optical light curve shows a pronounced plateau lasting for about 110 days. Temporal evolution of photospheric radius and color temperature during the plateau phase is determined by making black body fits. We estimate the ejected mass of $^{56}$Ni to be 0.06 $\pm$ 0.03 M$_\odot$. Using the expressions of Litvinova & Nadëzhin (1985) we estimate an explosion energy of (0.98 $\pm$ 0.25) $\times 10^{51}$ erg. We also present a single epoch radio observation of SN 2004et. We compare this with the predictions of the model proposed by Chevalier et al. (2006). These multi-wavelength studies suggest a main sequence progenitor mass of $\sim$ 20 M$_\odot$ for SN 2004et.

description: The evaluation of the electron-ion bremsstrahlung cross section exact to all orders in the Coulomb potential is computationally expensive due to the appearance of hypergeometric functions. Therefore tabulations are widely used. Here, we provide an approximate formula for the non-relativistic dipole process valid for all applicable relative velocities and photon energies. Its validity spans from the Born- to the classical regime and from soft-photon emission to the kinematic endpoint. The error remains below 3% (and widely below 1%) except at an isolated region of hard-photon emission at the quantum-to-classical crossover. We use the formula to obtain the thermally averaged emission spectrum and cooling function in a Maxwellian plasma and demonstrate that they are accurate to better than 2%.

REMARKS: Rondani (1848b: 78) described both sexes of Musca consanguinea from an unspecified number of specimens collected in South America by V. Ghiliani. Costa (1866: 34) listed two MZUN specimens numbered “708”. We found three syntypes in this study. Although Rondani (1848b: 63) only gave the type locality as “ Brasile ”, Papavero (1973: 343) gave a more accurate type locality based on a note in Spinola (1853) that said all specimens collected by Ghiliani in 1846 were collected in Belem, Pará, Brazil.

description: Energy case study: Effects of Arctic sea ice on energy production in mid-latitudes. Winter 2016-17 event identified as relevant by stakeholders in the energy sector The APPLICATE project releases its first case study that contributes to understanding the linkages between the Arctic and mid-latitudes. The document is mainly addressed to policy makers, although it can also be of interest for big energy associations (e.g., EWEA, IRENA, AREA) and global networks of Transmission System Operators (e.g., ENTSO-E), among others. This work has been the result of a joint effort between climate scientists, social scientists and science communication specialists taking part in the consortium and has counted with the collaboration of partners from the European H2020 project Sub-seasonal to seasonal predictions for energy (S2S4E). The case study describes a cold spell in winter 2016-17 that some energy producers, interviewed in S2S4E, identified as a relevant event affecting their businesses. The cold spell was accompanied by record-breaking low precipitation and wind speed over parts of western Europe, increasing energy demand and reducing renewable power generation, which contributed to an energy-security risk situation in France. In this first case study, the APPLICATE project explores potential linkages of the event highlighted by energy producers with Arctic changes in sea ice. Once these linkages are well-established and understood, future forecasts of extremely low sea ice extent (that also relate with forecasts of electricity demand and power generation) could be potentially valuable for assessing the risk for European energy systems.
A minimalist pilot-wave model for quantum electrodynamics

description: We present a way to construct a pilot-wave model for quantum electrodynamics. The idea is to introduce beables corresponding only to the bosonic degrees of freedom and not to the fermionic degrees of freedom of the quantum state. We show that this is sufficient to reproduce the quantum predictions. The beables will be field beables corresponding to the electromagnetic field and they will be introduced in a similar way to that of Bohm's model for the free electromagnetic field. Our approach is analogous to the situation in non-relativistic quantum theory, where Bell treated spin not as a beable but only as a property of the wavefunction. After presenting this model we also discuss a simple way for introducing additional beables that represent the fermionic degrees of freedom.

description: Space debris is a major problem in space exploration. International bodies continuously monitor a large database of orbiting objects and emit warnings in the form of conjunction data messages. An important question for satellite operators is to estimate when fresh information will arrive so that they can react timely but sparingly with satellite maneuvers. We propose a statistical learning model of the message arrival process, allowing us to answer two important questions: (1) Will there be any new message in the next specified time interval? (2) When exactly and with what uncertainty will the next message arrive? The average prediction error for question (2) of our Bayesian Poisson process model is smaller than the baseline in more than 4 hours in a test set of 50k close encounter events.

title: Hyperbolically embedded subgroups in terms of Fine graphs
Creators: name: Rashid, Farhan
Publisher: name: Memorial University of Newfoundland
Year: 2020

description: Since the 1980s, mathematicians have been studying hyperbolic groups, and hyperbolic geometry has been considered one of the most useful tools in geometric group theory. In the 2000s, a generalization of hyperbolic groups was introduced by Dahmani, Guiraldel and Osin, known as hyperbolically embedded subgroups. This notion has several applications in group theory and low dimensional topology. In this thesis, we introduce an alternative definition of hyperbolic embedded subgroup modelled on a characterization of a relatively hyperbolic group by Bowditch [2] and prove that our notion is equivalent to the original definition.

description: We show that color-breaking vacua may develop at high temperature in the Mini-Split Supersymmetry (SUSY) scenario. This can lead to a nontrivial cosmological history of the Universe, including strong first order phase transitions and domain wall production. Given the typical PeV energy scale associated with Mini-Split SUSY models, a stochastic gravitational wave background at frequencies around 1 kHz is expected. We study the potential for detection of such a signal in future gravitational wave experiments.

description: In this note, we extend our previous work [Phys. Lett. B 644, 7 (2007), astro-ph/0609597], and compare eleven interacting dark energy models with different couplings to the observational $H(z)$ data. However, none of these models is better than the simplest $Λ$CDM model. This implies that either more exotic couplings are needed in the cosmological models with interaction between dark energy and dust matter, or {\em there is no interaction at all}. We consider that this result is disadvantageous to the interacting dark energy models studied extensively in the literature.

description: ‘Intellectual property is the oil of the 21st century’, said Mark Getty, founder of the photo agency Getty Images. The agency no longer belongs to him, although he and executive director Jonathan Klein continue to hold shares in the company. In August 2012, the photo agency was sold to the US private equity company Carlyle for 3.3 billion dollars. This issue of the Junge Akademie Magazin takes up the subject of visualization in the dossier. How are things portrayed in science when they are too small to see? How do natural scientists construct the world of particles in general and for didactic reasons? How do they combine measured data in order to create a picture of the internal workings of a galaxy? Are there good and bad ways of handling pictures, for instance in medieval studies? Where are the limits of visualisation in life and in art? The way scientists visualise data can influence their future research, both in terms of content and in their career. Whether in the media, in academia, or in art – visuals are in demand more than ever. At the same time they are under pressure: with photo agencies, pricier agencies have had competition for years; so-called microstock agencies sell amateur photos in the cent range. Photo agencies double as archives, and archives do not always quote the correct sources: the history of an image and its use today can be decontextualised and thus lead to false conclusions – another subject in our focus. Finally: what role does digitalisation play in all of this? The internet is widely regarded as a large archive, but in his guest article, JA alumnus Oliver Grau asks whether contemporary culture and media art might be threatened by loss. On behalf of the editorial team, I hope you enjoy reading our magazine! Evelyn Runge

No entanto, a pastagem pelo gado dificulta a regeneração natural do estrato arbóreo, sobretudo nas áreas onde as condições climáticas e o solo são mais desfavoráveis. O consumo de sementes por animais domésticos e selvagens, os stresses abióticos (seca, temperaturas estivais elevadas e solos pobres) e a falta de condições pontuais do solo adequadas à germinação das sementes constituem grandes impedimentos ao seu estabelecimento e sobrevivência.

description: Musca frontalis Rondani, 1868
ORIGINAL DESCRIPTION: 1868a: 51.
TYPE LOCALITY: “Paris” (Robineau-Desvoidy 1830: 396) [type locality for Musca aurifacies Robineau-Desvoidy, 1830].
TYPE MATERIAL: see Remarks.
CURRENT STATUS: junior synonym of Musca domestica Linnaeus, 1758 (Pont 1986b: 91, Thompson & Pont 1994: 77); junior primary homonym of Musca frontalis Latreille, 1802 (Evenhuis & Pape 2020).
REMARKS: Rondani (1868a: 51) considered the males of Musca aurifacies Robineau-Desvoidy, 1830 and the females of Musca campestris Robineau-Desvoidy, 1830 as belonging to the same species but, instead of applying the Principle of Priority, incorrectly proposed the substitute name Musca frontalis. It is considered as a synonym of M. aurifacies Robineau-Desvoidy, 1830 by Bezzi & Stein (1907: 602) and of Musca domestica Linnaeus, 1758 by Pont (1986b: 91) and Thompson & Pont (1994: 77) but never as a valid species. The type material for M. frontalis will be the same as for the name it was proposed to replace, i. e., Musca aurifacies. There is no type of Musca aurifacies in the MNHN where the Robineau-Desvoidy’s collection is preserved (Muséum national d’Histoire naturelle 2020).

description: Various microswimmers move along circles rather than straight lines due to their swimming mechanisms, body shapes or hydrodynamic effects. Here, we adopt the concepts of stochastic thermodynamics to analyze circle swimmers confined in a two-dimensional plane, and study the trade-off relations between various physical quantities such as precision, energy cost and rotational speed. Based on these findings, we predict principles and strategies for designing microswimmers of special optimized functions under limited energy resource conditions, which will bring new experimental inspiration for designing smart motors.

description: We investigate the phenomenology of new abelian gauge bosons, which we denote as $X$ bosons, that suffer a mixed anomaly with the Standard Model, but are made self-consistent by the Green-Schwarz mechanism. A distinguishing aspect of the resulting effective theory is the decay of $X$ bosons into Standard Model gauge bosons, $X\to ZZ, WW, γZ$. We compute the production cross-section of the $X$ boson from vector boson fusion at the Large Hadron Collider. We study the $pp\to X\to ZZ\to 4l$ signal, and analyze the prospects of discovery. We argue that such a discovery could indirectly probe high energies, even up to the string scale.

description: We investigate magnetic instabilities in charge-neutral twisted bilayer graphene close to so-called "magic angles" using a combination of real-space Hartree-Fock and dynamical mean-field theories. In view of the large size of the unit cell close to magic angles, we examine a previously proposed rescaling that permits to mimic the same underlying flat minibands at larger twist angles. We find that localized magnetic states emerge for values of the Coulomb interaction $U$ that are significantly smaller than what would be required to render an isolated layer antiferromagnetic. However, this effect is overestimated in the rescaled system, hinting at a complex interplay of flatness of the minibands close to the Fermi level and the spatial extent of the corresponding localized states. Our findings shed new light on perspectives for experimental realization of magnetic states in charge-neutral twisted bilayer graphene.

On factorisation schemes for the electron parton distribution functions in QED

Publisher: name: arXiv
Year: 2021
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: The electron, positron, and photon Parton Distribution Functions (PDFs) of the unpolarised electron have recently been computed at the next-to-leading logarithmic accuracy in QED, by adopting the $\overline{\rm MS}$ factorisation scheme. We present here analogous results, obtained by working in a different framework that is inspired by the so-called DIS scheme. We derive analytical solutions relevant to the large-$z$ region, where we show that the behaviour of the PDFs depends in a dramatic way on whether running-$α$ effects are included to all orders, as opposed to being truncated to some fixed order. By means of suitable initial and evolution conditions, next-to-leading logarithmic accurate PDFs are obtained whose large-$z$ functional forms are identical to those of their leading logarithmic counterparts.

description: We present the implementation of updated stellar evolution recipes in the codes \texttt{Nbody6++GPU, MOCCA} and \texttt{McLuster}. We test them through numerical simulations of star clusters containing $1.1\times 10^5$ stars (with $2.0\times 10^4$ in primordial hard binaries) performing high-resolution direct $N$-body (\texttt{Nbody6++GPU}) and Monte-Carlo (\texttt{MOCCA}) simulations to an age of 10~Gyr. We compare models implementing either delayed or core-collapse supernovae mechanisms, a different mass ratio distribution for binaries, and white dwarf natal kicks enabled/disabled. Compared to \texttt{Nbody6++GPU}, the \texttt{MOCCA} models appear to be denser, with a larger scatter in the remnant masses, and a lower binary fraction on average. The \texttt{MOCCA} models produce more black holes (BHs) and helium white dwarfs (WDs), whilst \texttt{Nbody6++GPU} models are characterised by a much larger amount of WD-WD binaries. The remnant kick velocity and escape speed distributions are similar for the BHs and neutron stars (NSs), and some NSs formed via electron-capture supernovae, accretion-induced collapse or merger-induced collapse escape the cluster in all simulations. The escape speed distributions for the WDs, on the other hand, are very dissimilar. We categorise the stellar evolution recipes available in \texttt{Nbody6++GPU}, \texttt{MOCCA} and \texttt{Mcluster} into four levels: the one implemented in previous \texttt{Nbody6++GPU} and \texttt{MOCCA} versions (\texttt{level A}), state-of-the-art prescriptions (\texttt{level B}), some in a testing phase (\texttt{level C}), and those that will be added in future versions of our codes.

Derivatives of embedding functors I: the stable case

description: For smooth manifolds $M$ and $N$, let $\Ebar(M, N)$ be the homotopy fiber of the map $\Emb(M, N)\longrightarrow \Imm(M, N)$. Consider the functor from the category of Euclidean spaces to the category of spectra, defined by the formula $V\mapsto Σ^\infty\Ebar(M, N\times V)$. In this paper, we describe the Taylor polynomials of this functor, in the sense of M. Weiss' orthogonal calculus, in the case when $N$ is a nice open submanifold of a Euclidean space. This leads to a description of the derivatives of this functor when $N$ is a tame stably parallelizable manifold (we believe that the parallelizability assumption is not essential). Our construction involves a certain space of rooted forests (or, equivalently, a space of partitions) with leaves marked by points in $M$, and a certain ``homotopy bundle of spectra'' over this space of trees. The $n$-th derivative is then described as the ``spectrum of restricted sections'' of this bundle. This is the first in a series of two papers. In the second part, we will give an analogous description of the derivatives of the functor $\Ebar(M, N\times V)$, involving a similar construction with certain spaces of connected graphs (instead of forests) with points marked in $M$.

description: We report the observation of a new $D_{sJ}$ meson produced in $B^{+} \to \bar{D}^{0} D_{sJ} \to \bar{D}^{0} D^{0} K^{+}$. This state has a mass of $M=2708 \pm 9 ^{+11}_{-10} \rm{MeV}/{\it c}^{2}$, a width $Γ= 108 \pm 23 ^{+36}_{-31} ~\rm{MeV}/ {\it c}^{2}$ and a $1^{-}$ spin-parity. The results are based on an analysis of 449 million $B\bar{B}$ events collected at the $Υ(4S)$ resonance with the Belle detector at the KEKB asymmetric-energy $e^{+} e^{-}$ collider.

Halo-model signatures from 380,000 SDSS Luminous Red Galaxies with photometric redshifts

description: We analyze the small-scale clustering in "MegaZ-LRG", a large photometric-redshift catalogue of Luminous Red Galaxies extracted from the imaging dataset of the Sloan Digital Sky Survey. MegaZ-LRG, presented in a companion paper, spans the redshift range 0.4 < z < 0.7 with an r.m.s. redshift error dz ~ 0.03(1+z), covering 5,914 deg^2 to map out a total cosmic volume 2.5 h^-3 Gpc^3. In this study we use 380,000 photometric redshifts to measure significant deviations from the canonical power-law fit to the angular correlation function in a series of narrow redshift slices, in which we construct volume-limited samples. These deviations are direct signatures of the manner in which these galaxies populate the underlying network of dark matter haloes. We cleanly delineate the separate contributions of the "1-halo" and "2-halo" clustering terms and fit our measurements by parameterizing the halo occupation distribution N(M) of the galaxies. Our results are successfully fit by a "central" galaxy contribution with a "soft" transition from zero to one galaxies, combined with a power-law "satellite" galaxy component, the slope of which is a strong function of galaxy luminosity. The large majority of galaxies are classified as central objects of their host dark matter haloes rather than satellites in more massive systems. The effective halo mass of MegaZ-LRG galaxies lies in the range log_10 (M_eff / h^-1 M_sol) = 13.61 - 13.8 (increasing with redshift, assuming large-scale normalization sigma_8 = 0.8) for corresponding number densities in the range n_g = 5.03 - 0.56 x 10^-4 h^3 Mpc^-3. Our results confirm the usefulness of the halo model for gaining physical insight into the patterns of galaxy clustering.

description: The first limit on the branching ratio of the electric charge-nonconserving invisible muon decay $Br(μ^+ \to invisible) < 5.2 \times 10^{-3}$ is obtained from the recently reported results on new determination of the Fermi constant from muon decays. The results of a feasibility study of a new proposed experiment for a sensitive search for this decay mode at the level of a few parts in 10^{11} are presented. Constrains on the $τ\to invisible$ decay rate are discussed. These leptonic charge-nonconserving processes may hold in four-dimensional world in models with infinite extra dimensions, thus making their searches complementary to collider experiments probing new physics.

The effect of foliar applications of sprays made from kelp (macrocystis integrifolia) on growth of phaseolus vulgaris : b possible role of algal phytohormone-like substances
Creators: name: Radley, Reed Alan
Publisher: name: University of British Columbia
Year: 2010

description: The effects of two applications of foliar sprays made from kelp (Macrocystis intearifolia Bory) on growth of beans (Phaseolus vulgaris L.) under three moisture regimes were investigated. Date of kelp harvest had little effect on plants grown in water excess or deficit conditions, although means for kelp collected in spring tended to be higher. On soils maintained near field capacity, spray made from kelp collected in July resulted in increases in some bean yield components beyond the effects of kelp collected in spring or fall. The effect of storage of liquefied kelp at room temperature was also investigated and found to be soil moisture dependent. Leaf and root weights of plants grown in field capacity and dry soil respectively were lower for plants treated with kelp aged for 118 days compared to plants treated with kelp stored for longer or shorter durations. In wet soil conditions, the effect of sprays on plant height was reduced by storage of the liquefied kelp. Kelp extracts were fractionated by solvent partition. The butanolic fraction was shown to increase significantly many yield variables under wet soil conditions. This fraction had cytokinin-like activity in two bioassay systems, and contained substances co-eluting with isopentenyl adenine and zeatin in column, thin layer, and gas-liquid chromatography systems. Non-significant increases for some plant yield components resulting from application of unfractionated kelp paralleled these increases. A kelp fraction with undefined constituents increased some yield variables of plants grown in field capacity soil, as did a fraction with auxin and gibberellin-like activities in bioassay. The presence of inhibitors in the kelp was indicated by significantly lower pod yields under dry soil conditions, and a reduction in cytokinin-like bioassay activity when increasing amounts of kelp were assayed. The possibility that phytohormone deficits resulting from root stress are ameliorated by some components of the kelp spray is discussed.
