description: Soft gluon exponentiation in non-abelian gauge theories can be described in terms of webs. So far this description has been restricted to amplitudes with two hard partons, where webs were defined as the colour-connected subset of diagrams. Here we generalise the concept of webs to the multi-leg case, where the hard interaction involves non-trivial colour flow. Using the replica trick from statistical physics we solve the combinatorial problem of non-abelian exponentiation to all orders. In particular, we derive an algorithm for computing the colour factor associated with any given diagram in the exponent. The emerging result is exponentiation of a sum of webs, where each web is a linear combination of a subset of diagrams that are mutually related by permuting the eikonal gluon attachments to each hard parton. These linear combinations are responsible for partial cancellation of subdivergences, conforming with the renormalization of a multi-leg eikonal vertex. We also discuss the generalisation of exponentiation properties to beyond the eikonal approximation.

description: The recent discovery of gravitational waves by the LIGO-Virgo collaboration created renewed interest in the investigation of alternative gravitational wave detector designs, such as small scale resonant detectors. In this article, it is shown how proposed small scale detectors can be tested by generating dynamical gravitational fields with appropriate distributions of moving masses. A series of interesting experiments will be possible with this setup. In particular, small scale detectors can be tested very early in the development phase and tests can be used to progress quickly in their development. This could contribute to the emerging field of gravitational wave astronomy.
Mass Transfer, Transiting Stream and Magnetopause in Close-in Exoplanetary Systems with Applications to WASP-12

description: We study mass transfer by Roche lobe overflow in close-in exoplanetary systems. The planet's atmospheric gas passes through the inner Lagrangian point and flows along a narrow stream, accelerating to 100-$200\kms$ velocity before forming an accretion disk. We show that the cylinder-shaped accretion stream can have an area (projected in the plane of the sky) comparable to that of the planet and a significant optical depth to spectral line absorption. Such a "transiting cylinder" may produce an earlier ingress of the planet transit, as suggested by recent HST observations of the WASP-12 system. The asymmetric disk produced by the accretion stream may also lead to time-dependent obscuration of the star light and apparent earlier ingress. We also consider the interaction of the stellar wind with the planetary magnetosphere. Since the wind speed is subsonic/sub-Alfvenic and comparable to the orbital velocity of the planet, the head of the magnetopause lies eastward relative to the substellar line (the line joining the planet and the star). The gas around the magnetopause may, if sufficiently compressed, give rise to asymmetric ingress/egress during the planet transit, although more works are needed to evaluate this possibility.

Organized cell movement is a major mechanism underlying facial morphogenesis
Creators: name: Danescu, Adrian
Publisher: name: University of British Columbia
Year: 2019

description: The mechanisms of embryonic facial morphogenesis are poorly understood because direct visualization of the growing embryo is challenging. We refined an organ culture method to visualize the individual cells within the frontonasal mass at high resolution. The fate of the frontonasal mass is to form the premaxilla, nasal septum and facial midline. During normal development the frontonasal mass begins as wide prominence but then the nasal pits relocate to the midline, causing dramatic medio-lateral narrowing. We confirmed that in vitro, the frontonasal mass narrowed over a 48h period, similar to in vivo. Removing the eyes, brain and most of the surrounding face did not impede facial narrowing suggesting intrinsic rather than extrinsic mechanisms were involved. Indeed, blocking the cytoskeletal rearrangements with the Rho GTPase inhibitor, Y27632 (ROCKi) completely inhibited narrowing. Organ cultures were stained with Hoechst dye and imaged using confocal microscopy. Nuclei were imaged for 4-6 hours at 10 minute intervals. Manual cell tracking was carried out across the frontonasal mass. At 10X magnification, striking patterns of order, disorder and then order in vectors of movement were observed. In ROCKi treated cultures there was disorder for the entire culture period. Clustering the vectors according to similarity of the angle revealed large groups of cells were moving in a similar manner in the controls but in the ROCKi treated cultures, clusters were poorly defined and smaller in size. In order to assess symmetry and patterns of divergence and convergence the vector data was interpolated over an evenly spaced grid. The controls had a high degree of right-left symmetry whereas the ROCKi-treated cultures lacked symmetry. We also examined the data to look for sources or sinks in the cell movements. Divergence and convergence bands were located in the mediolateral axis with branches at the lateral edges. The change in direction from convergence to divergence and then back to convergence was rapid, often switching within 20 minutes. This rapid cycling is on the same scale as GTPase switching. Our data suggest that orchestrated mesenchymal cell behaviors, mediated by Rho GTPases are involved in convergent-extension in the face.

description: Scorpius-Centaurus OB2 association (Sco-Cen) is the nearest region of massive star formation that represents a local laboratory to study a wide variety of topics, from young circumstellar disks and planets in the making to the insight into the initial mass function due to its proximity. A precision astrometry from Gaia helps to significantly extend its membership lists. However, age determination of young and low-mass stars from evolutionary models remains nontrivial.
 We analysed Sco-Cen with Chronostar, a novel Bayesian technique for kinematic age determination that performs an iterative search for members in the 6D position-kinematic space. Membership selection is based purely on the kinematics. Our Sco-Cen model consists of 8 kinematically distinct components comprising nearly 9000 stars. Each of the components has an independently-fit kinematic age that is consistent with the isochronal age from the literature.

description: We describe using DBSCAN and HDBSCAN clustering algorithms applied to a list of preliminary selected pairs of stars, with parameters expected to be found within stellar streams and comoving groups. To test our approach, we construct a model population of background stars, and use pair-constructing and clustering algorithm on it. Transitioning from stars to pairs highlights the comoving and dense structures, which makes them much more apparent targets for clustering algorithm. Modelling shows that these apparent overdensities in pairs do not appear in the uniform background model.

Analytic properties of high energy production amplitudes in N=4 SUSY

Publisher: name: arXiv
Year: 2010
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: We investigate analytic properties of the six point planar amplitude in N=4 SUSY at the multi-Regge kinematics for final state particles. For inelastic processes the Steinmann relations play an important role because they give a possibility to fix the phase structure of the Regge pole and Mandelstam cut contributions. These contributions have the Moebius invariant form in the transverse momentum subspace. The analyticity and factorization constraints allow us to reproduce the two-loop correction to the 6-point BDS amplitude in N=4 SUSY obtained earlier in the leading logarithmic approximation with the use of the s-channel unitarity. The exponentiation hypothesis for the remainder function in the multi-Regge kinematics is also investigated. The 6-point amplitude in LLA can be completely reproduced from the BDS ansatz with the use of the analyticity and Regge factorization.

description: In this paper we report an investigation on the ferromagnetic state and the nature of ferromagnetic transition of nanoparticles of $\mathrm{La_{0.67}Ca_{0.33}MnO_3}$ using magnetic measurements and neutron diffraction. The investigation was made on nanoparticles with crystal size down to $15$ nm. The neutron data show that even down to a size of $15$ nm the nanoparticles show finite spontaneous magnetization ($M_S$) although the value is much reduced compared to the bulk sample. We observed a non-monotonic variation of the ferromagnetic to paramagnetic transition temperature $T_C$ with size $d$ and found that $T_C$ initially enhances on size reduction, but for $d < 50$ nm it decreases again. The initial enhancement in $T_C$ was related to an increase in the bandwidth that occured due to a compaction of the Mn-O bond length and a straightening of the Mn-O-Mn bond angle, as determined form the neutron data. The size reduction also changes the nature of the ferromagnetic to paramagnetic transition from first order to second order with critical exponents approaching mean field values. This was explained as arising from a truncation of the coherence length by the finite sample size.

Manner demonstratives in Barayin (Chadic)
Creators: name: Lovestrand, Joseph
Publisher: name: Zenodo
Year: 2020
Subjects: Linguistics, Syntax, Semantics, Barayin, Chadic

description: This study examines the primary functions of a manner demonstrative teyi in a 28,000-word corpus of Barayin—a Chadic language spoken by 6,000 people in the Guera region of Chad (Lovestrand 2012). Nikitina & Treis (2020) define manner demonstratives as “deictic expressions that identify a way of carrying out an event or the extent to which a property holds”. The manner demonstrative teyi ‘like this’ occurs 295 times in the Barayin corpus. In its core function, teyi refers to a manner or property that is in the immediate (discourse) context or indicated by gesture. The function of the manner demonstrative in Barayin differs from Wan and Kambaata in that manner demonstratives in Barayin are not regularly used in cataphoric reference to reported speech. Rather, the adnominal demonstrative gi is used. Manner demonstratives in Barayin frequently have other extended uses such as an “approximate use” (König 2017) adding vagueness, e.g. ‘or so’. Syntactically, manner demonstratives in Barayin have a similar distribution to adverbs, as in Kambaata. Nikitina & Treis hypothesize that syntactic properties can partially predict meaning extension of manner demonstratives, and the properties of manner demonstratives in Barayin support their hypothesis since the extended uses of Barayin manner demonstratives partially overlap with the uses of manner demonstratives in Kambaata (adverb), but not Wan (sentence-final marker).

Diese wurde mittels statischer Lichtstreuung, Trans-missionselektronenmikroskopie (TEM), thermogravimetrischer Analyse, rheologischer Messung und Oberflächenspan-nungsmessung charakterisiert. Zudem wurden Tintenstrahldrucktests und eine Analyse der thermischen Leitfähigkeit des gedruckten Materials durchgeführt. Das Ergebnis der Untersuchung ist ein Material, das den Tintenstrahldruck von Kom-positen mit einem Keramikgehalt von 50 Vol% und einer thermischen Leitfähigkeit von 1,2 W/(m·K) ermöglicht.

description: In this paper we examine the cosmological consequences of fourth order Galileon gravity. We carry out detailed investigations of the underlying dynamics and demonstrate the stability of one de Sitter phase. The stable de Sitter phase contains a Galileon field $π$ which is an increasing function of time (\dotπ>0). Using the required suppression of the fifth force, supernovae, BAO and CMB data, we constrain parameters of the model. We find that the $π$ matter coupling parameter $β$ is constrained to small numerical values such that $β$<0.02. We also show that the parameters of the third and fourth order in the action (c_3,c_4) are not independent and with reasonable assumptions, we obtain constraints on them. We investigate the growth history of the model and find that the sub-horizon approximation is not allowed for this model. We demonstrate strong scale dependence of linear perturbations in the fourth order Galileon gravity.

description: After impact onto a smooth dry surface, a drop of viscous liquid initially spreads in the form of a thick lamella. If the drop splashes, it first emits a thin fluid sheet that can ultimately break up into droplets causing the splash. Ambient gas is crucial for creating this thin sheet. The time for sheet ejection, $t_{ejt}$, depends on impact velocity, liquid viscosity, gas pressure and molecular weight. A central air bubble is trapped below the drop at pressures even below that necessary for this sheet formation. In addition, air bubbles are entrained underneath the spreading lamella when the ejected sheet is present. Air entrainment ceases at a lamella velocity that is independent of drop impact velocity as well as ambient gas pressure.

description: In this paper we present a new method to estimate a foreground cleaned Cosmic Microwave Background (CMB) map at a resolution of $1^\circ$ by minimizing the non-Gaussian properties of the cleaned map which arise dominantly due to diffuse foreground emission components from the Milky Way. We employ simple kurtosis statistic as the measure of non-Gaussian properties and perform a linear combination of 5 frequency maps provided by Wilkinson Microwave Anisotropy Probe (WMAP) in its 7 year data release in such a way that the cleaned map has a minimum kurtosis which leads to a non-Gaussianity minimized, foreground cleaned CMB map. We validate the method by performing Monte-Carlo simulations. To minimize any residual foreground contamination from the cleaned map we flag out region near the galactic plane based upon results from simulations. Outside the masked region our new estimate of CMB map matches well with the WMAP's ILC map. A simple pseudo-$C_l$ based CMB TT power spectrum derived from the non-gaussianity minimized map reproduces the earlier results of WMAP's power spectrum. {\it An important advantage of the method is that it does not introduce any negative bias in angular power spectrum in low multipole regime, unlike usual ILC method.} Comparing our results with the previously published results we argue that CMB results are robust with respect to specific foreground removal algorithms employed.

description: Sparse methods for supervised learning aim at finding good linear predictors from as few variables as possible, i.e., with small cardinality of their supports. This combinatorial selection problem is often turned into a convex optimization problem by replacing the cardinality function by its convex envelope (tightest convex lower bound), in this case the L1-norm. In this paper, we investigate more general set-functions than the cardinality, that may incorporate prior knowledge or structural constraints which are common in many applications: namely, we show that for nondecreasing submodular set-functions, the corresponding convex envelope can be obtained from its \lova extension, a common tool in submodular analysis. This defines a family of polyhedral norms, for which we provide generic algorithmic tools (subgradients and proximal operators) and theoretical results (conditions for support recovery or high-dimensional inference). By selecting specific submodular functions, we can give a new interpretation to known norms, such as those based on rank-statistics or grouped norms with potentially overlapping groups; we also define new norms, in particular ones that can be used as non-factorial priors for supervised learning.
‘Native Europeans’ and European Memories. The building of a European consciousness among young people

description: Since its constitution the European Union has sought to promote a European identity and with it a shared European memory, through a process of transnationalization of ideas and values, to be placed at the basis of the European society to be constituted, according to the idea of the United States of Europe. The essay focuses on the processes leading to the formation of European Memories among young people, using focus groups as technique. The generation that is the subject of this research can be defined as “native Europeans”, since these individuals were born at the turn of 2004, the year in which the European Union assumed its current composition and welcomed almost all the European states. As the research shows, although there is more than one obstacle to the development of European memories, both transnational practices and school education can help it to take root. Keywords: Europe, Young People, European Memories. Fin dalla sua costituzione l’Unione europea ha cercato di promuovere un’identità e delle memorie condivise tra i suoi cittadini; ciò è avvenuto in larga parte attraverso il processo di transnazionalizzazione delle idee e dei valori fondanti europei, in parte minore grazie a specifiche azioni promosse dalla UE. Il saggio si concentra sui processi che portano alla formazione di memorie europee tra i giovani, utilizzando come tecnica di rilevazione il focus group. In particolare, oggetto della ricerca è la formazione di memorie europee tra i cosiddetti "nativi europei", ovvero quei giovani nati agli inizi degli anni Duemila, durante i quali l'Unione Europea ha assunto la sua attuale composizione. I risultati della ricerca mostrano come, nonostante vi sia più di un ostacolo, sia le pratiche transnazionali sia, in particolare, l'educazione scolastica rappresentino dei fattori decisivi nell'incoraggiare questo processo di maturazione di memorie europee tra i giovani. Parole chiave: Europa, Giovani, Memorie europee.

description: Ainu language is traditionally considered as a language isolate. Two main categories of attempts linked Ainu with (1) Altaic or Eurasiatic languages, and (2) Austronesian or Austroasiatic languages. However, these hypotheses have not been widely accepted. The present study argues that Ainu is genealogically connected with the Na-Dene languages in North America. Evidence is presented in three aspects: (1) the existence of many possible cognate etymologies that distributed in body parts, animal-related nouns, artificial objects, and other basic word categories; (2) homologous semantic networks of cognate words and word stems that indicate deep linguistic and cultural intertwines; and (3) regular sound correspondences that are tentatively summarized between Ainu and Na-Dene languages. The position of Ainu in the Dene-Yeniseian and the Dene-Caucasian hypotheses is also discussed. The Ainu-Dene connection, if true, will add an important link between New World and Old World languages, and will shed light on the early migrations of peoples in Beringia and Eurasia.

description: The neutron star spin down imposes a balance between the energy and angular momentum (E/L) losses of a pulsar. This translates into constraints on the region of emission. The E/L balance may be cogent in discriminating among the models of gamma-ray production. Hence, models which require the release of the entire luminosity at the polar caps should be excluded. Also models where the radiative zone is well inside the speed of light radius have some difficulties. It is argued that a local unbalance of E/L should generate a global instability of the magnetosphere, possibly quenching the emission at the polar caps.

Dalla sacralità nazionale alla sacralità europea
Creators: name: Orsingher, Enrico
Publisher: name: De Europa

description: The Isonzo, the Tagliamento and the Piave are three rivers which played an important role in the events of the Italian front during World War I. For this reason, all three were declared “Sacred River of the Homeland”. This expression is one which now resonates in the collective imaginary, largely thanks to the road signs which are placed at the entrance of bridges spanning the rivers, at times directly beneath the name of the river itself. In 2017, some municipalities in the area of the Isonzo replaced the well-known label with a more European phrasing, redefining the river as a “Sacred River of the European Peoples”. This initiative sparked a controversy which transformed the memory of the sacredness of these Italian rivers into a political battleground, and which even saw a number of the signs vandalized. Through a systematic classification and analysis of all of the road signs placed along the course of the three rivers which directly refer to them, this article examines the multiscalarity of the different memorial labels, in order to understand if they are intrinsically doomed to be in competition with one another or if they can in fact coexist. This study also represents an opportunity for highlighting the underlying rationales and dynamics of the road sign as a highly specific medium, and its role in the transmission and reception of memorial messages. Keywords River – Sacredness – Memorial Multiscalarity – World War I – Road Sign Tre fiumi italiani – l'Isonzo, il Tagliamento e il Piave – hanno avuto un ruolo di primaria importanza nell'evolvere degli eventi sul fronte italo-austriaco della prima guerra mondiale e, per questo, sono stati dichiarati fiumi “sacri alla Patria”. Tale espressione è entrata nell'immaginario collettivo grazie anche ai segnali di localizzazione territoriale i quali, posti nei pressi dei ponti, a volte riportano la dicitura sotto il nome del fiume. Nel 2017, alcuni comuni isontini riformulano la celebre espressione in senso europeista, definendo l'Isonzo “fiume sacro ai popoli d'Europa”. L'iniziativa genera una tensione memoriale che, oltre a trasformare la memoria della sacralità dei fiumi in un terreno di scontro politico, sfocia in gesti iconoclastici nei confronti della cartellonistica. Attraverso una catalogazione sistematica e l'esame di tutti i segnali di localizzazione territoriale presenti lungo i tre fiumi, il presente articolo propone un'analisi della multiscalarità di referenze memoriali, al fine di capire se queste siano sempre per loro natura destinate a entrare in concorrenza o se possano, al contrario, coesistere. Questo studio rappresenta anche un'occasione per mettere in luce le logiche e le dinamiche proprie a un medium così particolare, in termini di trasmissione e ricezione del messaggio memoriale.

Interference in complex quantum systems : from localization in high-dimensional lattices to surface spin echo with molecules
Creators: name: Cantin, Joshua Tyler
Publisher: name: University of British Columbia
Year: 2019

description: This thesis considers (1) novel manifestations and applications of quantum interference in complex systems and (2) development of new approaches to study complex quantum systems. First, I examine a general model of particles with long-range hopping amplitudes. For at least 30 years, it has been widely accepted that these particles do not undergo Anderson localization in 3D lattices. We show that these particles do undergo Anderson localization in 3D lattices if their hopping amplitudes are isotropic. In contrast, particles with anisotropic long-range hopping appear to follow the widely held expectations. We show these results by demonstrating that cooperative shielding extends to 3D cubic lattices with isotropic long-range hopping, but not with anisotropic long-range hopping and by computing the scaling behaviour of participation ratios and energy level statistics. Secondly, I develop a fully quantum mechanical model of molecular surface spin-echo experiments, which study surface properties and dynamics by scattering molecules off the sample surface. This model, based on the transfer matrix method, incorporates molecular hyperfine degrees of freedom, allows for the efficient calculation of the experimental signal given a molecule-surface scattering matrix, and permits us to begin addressing the inverse scattering problem. This fully quantum model is required to properly describe these experiments as the semi-classical methods used to describe experiments using helium-3 atoms do not take magnetic-field induced momentum changes into account. We apply our method to the case of ortho-hydrogen and then apply Bayesian optimization to determine the molecule-surface scattering matrix elements from a calculated signal, for a scattering matrix defined by three parameters. Our work sets the stage for Bayesian optimization to solve the inverse scattering problem for these experiments. Finally, I propose using Bayesian model calibration to improve the convergence of Monte Carlo calculations in regions where the sign problem or critical slowing down are an issue. Specifically, Bayesian model calibration would correct poorly converged Monte Carlo calculations with the information from a small number of well-converged Monte Carlo calculations. As a simple proof of principle demonstration, we apply Bayesian model calibration to a diagrammatic Monte Carlo calculation of the scattering length of a spherical potential barrier.

description: In this paper we investigate the LHC potential for discovering doubly-charged vector bileptons considering the measurable process $p,p$ $\rightarrow$ $e^{\mp}e^{\mp}μ^{\pm}μ^{\pm} X$. We perform the study using four different bilepton masses and three different exotics quark masses. Minimal LHC integrated luminosities needed for discovering and for setting limits on bilepton masses are obtained for both 7 TeV and 14 TeV center-of-mass energies. We find that these spectacular signatures can be observed at the LHC in the next years up to a bilepton mass of order of 1 TeV.
