description: An algebraic description of basic discrete symmetries (space reversal P, time reversal T and their combination PT) is studied. Discrete subgroups of orthogonal groups of multidimensional spaces over the fields of real and complex numbers are considered in terms of fundamental automorphisms of Clifford algebras. In accordance with a division ring structure, a complete classification of automorphisms groups is established for the Clifford algebras over the field of real numbers. The correspondence between eight double coverings (Dabrowski groups) of the orthogonal group and eight types of the real Clifford algebras is defined with the use of isomorphisms between the automorphism groups and finite groups. Over the field of complex numbers there is a correspondence between two nonisomorphic double coverings of the complex orthogonal group and two types of complex Clifford algebras. It is shown that these correspondences associate with a well-known Atiyah-Bott-Shapiro periodicity. Generalized Brauer-Wall groups are introduced on the extended sets of the Clifford algebras. The structure of the inequality between the two Clifford-Lipschitz groups with mutually opposite signatures is elucidated. The physically important case of the two different double coverings of the Lorentz groups is considered in details.

description: The experimental program for the study of the rare kaon decays, K -> pnn, is summarized. A review of recent results is provided along with a discussion of prospects for the future of this program. The primary focus of the world-wide kaon program is the two golden modes: K+ -> pnn and KL -> pnn. The first step in an ambitious program to precisely measure both branching ratios has been successfully completed with the observation of two K+ -> pnn events by E787. The E949 experiment is poised to reach an order of magnitude further in sensitivity and to observe ~10 Standard Model events, and the CKM experiment should observe ~100 SM events by the end of this decade. Limits on the neutral analog KL -> pnn have been set by KTeV and within the next couple of years will be pushed by E391a. Measurements of the branching ratio should be made within the next 10 years by KOPIO, with a goal of ~50 events, and at the JHF, with a goal of up to 1000 events.

description: Digital Transformation, the articulation of a company’s vision on how to use information and data supported by technology to enhance its market position and to create customer value, has an impact on organizations business processes, products and services. Achieving the state of digital transformation also referred to as digitalization, is rapidly becoming an imperative for organizations. In this transformation many organizations adapt the practice of running their IT in two speeds, one focused on predictability and one focused on exploration. Governing these two different paces in one organization is complex. Organizations are seeking methods to govern and manage this complexity and advance towards full digital transformation. This case study performs a literature analysis of existing documentation involving bimodal IT. Based on existing research a distinction is made of the different archetypes that can occur in a bimodal IT environment. This distinction is enhanced with specific practices being identified for governing the different archetypes. Recommendations are identified for both organizations seeking to deploy a form of Bimodal IT or seeking to move forward. Also, suggestions for further research are given.

description: This research investigates the concepts and perceptions of ‘social mobility’, which can simply be described as the movement of people or a group of people within or between the social strata of the society (Sorokin, 1959), in a rarely studied context of rural-urban migration, marginalization and cultural heritage in the state of Rajasthan, India. The case study is focused on the ‘Manganiyar’ and ‘Langa’ desert tribes of Rajasthan, who belong to the traditional classes of the Rajasthani Folk music.

Additionally, it aims to understand how the cultural heritage of these tribes, help improve or not improve, the tribes’ positive movement on the ladder of social mobility, otherwise simply known as ‘upward mobility’.

Primarily, this study explores the perceptions of social and cultural mobility India, where marginalization and social stratification is still very prominent, even after 68 years of Independence. By contextualizing the age-old system of social hierarchies in India from the perspective of social mobility in lower classes of the society, this research aims to increase the understanding between policy, power, privilege and social inequality.

The research used qualitative research methods such as interviews of the migrants and qualitative data review of government policies and programs for folk artists. The results of this research show trends towards higher horizontal social mobility and also a significant positive impact on the vertical social mobility for the migrants i.e. the Manganiyar and Langa tribes that are engaged in non-traditional jobs. On the contrary, the migrants engaged in traditional jobs sometimes experience vertical social mobility after migration, but there is no upward mobility thereafter. The antithesis is found to be true in specific circumstances where indicators of social mobility are bent heavily towards income and prominence within the traditional job itself.

description: We analyze a system of globally coupled logistic maps with asynchronous updating. We show that its dynamics differs considerably from that of the synchronous case. For growing values of the coupling intensity, an inverse bifurcation cascade replaces the structure of clusters and ordering in the phase diagram. We present numerical simulations and an analytical description based on an effective single-element dynamics affected by internal fluctuations. Both of them show how global coupling is able to suppress the complexity of the single-element evolution. We find that, in contrast to systems with synchronous update, internal fluctuations satisfy the law of large numbers.

We exclusively reconstruct one neutral B meson in the semileptonic B^0 \to D^{*-}\ell^+νdecay mode and identify the flavor of the accompanying B meson from its decay products. From the distribution of the time intervals between the two flavor-tagged B meson decay points, we obtain Delta m_d = (0.494 +- 0.012 +- 0.015) ps^{-1}, where the first error is statistical and the second error is systematic.

Investigations of anisotropic flow using multi-particle azimuthal correlations in pp, p-Pb, Xe-Xe, and Pb-Pb collisions at the LHC
Creators: name: ALICE Collaboration

Year: 2019
Subjects: subject: Nuclear Experiment (nucl-ex)

description: Measurements of anisotropic flow coefficients ($v_n$) and their cross-correlations using two- and multi-particle cumulant methods are reported in collisions of pp at $\sqrt{s} = 13$ TeV, p-Pb at $\sqrt{s_{_{\rm NN}}} = 5.02$ TeV, Xe-Xe at $\sqrt{s_{_{\rm NN}}} = 5.44$ TeV, and Pb-Pb at $\sqrt{s_{_{\rm NN}}} = 5.02$ TeV recorded with the ALICE detector. The multiplicity dependence of $v_n$ is studied in a very wide range from 20 to 3000 particles produced in the mid-rapidity region $|η|<0.8$ for the transverse momentum range $0.2 < p_{\rm T} < 3.0$ GeV/$c$. An ordering of the coefficients $v_2 > v_3 > v_4$ is found in pp and p-Pb collisions, similar to that seen in large collision systems, while a weak $v_2$ multiplicity dependence is observed relative to nucleus-nucleus collisions in the same multiplicity range. Using a novel subevent method, $v_{2}$ measured with four-particle cumulants is found to be compatible with that from six-particle cumulants in pp and p-Pb collisions. The magnitude of the correlation between $v_n^2$ and $v_m^2$, evaluated with the symmetric cumulants SC$(m,n)$ is observed to be positive at all multiplicities for $v_2$ and $v_4$, while for $v_2$ and $v_3$ it is negative and changes sign for multiplicities below 100, which may indicate a different $v_n$ fluctuation pattern in this multiplicity range. The observed long-range multi-particle azimuthal correlations in high multiplicity pp and p-Pb collisions can neither be described by PYTHIA 8 nor by IP-Glasma+MUSIC+UrQMD model calculations, and hence provide new insights into the understanding of collective effects in small collision systems.

Involutive Bases of Polynomial Ideals

description: In this paper we consider an algorithmic technique more general than that proposed by Zharkov and Blinkov for the involutive analysis of polynomial ideals. It is based on a new concept of involutive monomial division which is defined for a monomial set. Such a division provides for each monomial the self-consistent separation of the whole set of variables into two disjoint subsets. They are called multiplicative and non-multiplicative. Given an admissible ordering, this separation is applied to polynomials in terms of their leading monomials. As special cases of the separation we consider those introduced by Janet, Thomas and Pommaret for the purpose of algebraic analysis of partial differential equations. Given involutive division, we define an involutive reduction and an involutive normal form. Then we introduce, in terms of the latter, the concept of involutivity for polynomial systems. We prove that an involutive system is a special, generally redundant, form of a Groebner basis. An algorithm for construction of involutive bases is proposed. It is shown that involutive divisions satisfying certain conditions, for example, those of Janet and Thomas, provide an algorithmic construction of an involutive basis for any polynomial ideal. Some optimization in computation of involutive bases is also analyzed. In particular, we incorporate Buchberger's chain criterion to avoid unnecessary reductions. The implementation for Pommaret division has been done in Reduce.

description: Recent work on single bubble sonoluminescence (SBSL) has shown that many features of this phenomenon, especially the dependence of SBSL intensity and stability on experimental parameters, can be explained within a hydrodynamic approach. More specifically, many important properties can already be derived from an analysis of bubble wall dynamics. This dynamics is conveniently described by the Rayleigh-Plesset (RP) equation. In this work we derive analytical approximations for RP dynamics and subsequent analytical laws for parameter dependences. These results include (i) an expression for the onset threshold of SL, (ii) an analytical explanation of the transition from diffusively unstable to stable equilibria for the bubble ambient radius (unstable and stable sonoluminescence), and (iii) a detailed understanding of the resonance structure of the RP equation. It is found that the threshold for SL emission is shifted to larger bubble radii and larger driving pressures if surface tension is enlarged, whereas even a considerable change in liquid viscosity leaves this threshold virtually unaltered. As an enhanced viscosity stabilizes the bubbles against surface oscillations, we conclude that the ideal liquid for violently collapsing, surface stable SL bubbles should have small surface tension and large viscosity, although too large viscosity (>40 times the viscosity of water) will again preclude collapses.

description: With the expected increase of e-commerce activity, we can expect the share of delivery vehicles in cities to rise as well. On the one hand, this puts great pressure on cities and surrounding areas as emissions rise and space becomes scarce. On the other hand, people are adjusting their travel behaviour such that the increase in e-commerce affects not only last-mile delivery but also private passenger traffic. This paper presents an integrated approach of modelling last-mile deliveries using an agent-based travel demand model. It is intended to account for reciprocal effects between online shopping behaviour and last-mile deliveries. The package orders are generated by agents in the study area and distributed among the package centres. For each package centre, the tour for each delivery agent is created. The presented model allows for the simultaneous simulation of private trips and last-mile deliveries and thus realistic delivery conditions: the model can detect e.g. if an agent or another household member is at home to receive their order. We have applied the model to the city of Karlsruhe, Germany, and describe first results of that simulation. Application of the model allows for a detailed analysis e.g. of delivery success rates both in terms of time and space. The presented modelling framework provides insight into effects of last-mile deliveries on a transportation system and can be availed to analyse policy measures or alternative delivery strategies.

description: We point out that the physics at the extreme IR---cosmology---might provide tests of the physics of the extreme UV---the Weak Gravity Conjecture. The current discrepancies in the determination of $H_0$ may hint at a modification of $Λ$CDM. An extension which may fit better comprises of an early contribution to dark energy which `decays' into relativistic matter. On the other hand the discourse on WGC to date suggests that fields which support cosmic acceleration may produce relativistic matter after they traverse a $\sim$ Planckian distance in field space. We explain how this offers a simple realization of the requisite cosmic phenomenology. Thus if the resolution of $H_0$ discrepancies is really early dark energy that ends with a shower of relativistic matter and the current ideas on WGC are indicative, this may be a rare opportunity to link the two extreme limits of quantum field theory.

description: Numerous accidents at tailing disposal sites have occurred due to dam failure and geotechnical instability. The uncontrolled spreading of pollution into the surrounding environment, illustrates over and over again the need for safe and effective management of these kinds of sites. Safe and effective management measures can only be implemented on the basis of a thorough understanding of the physical, chemical and biological processes taking place at the tailing facilities. After implementation of the necessary measures, ongoing monitoring can verify the proper functioning of the rehabilitated tailing disposal sites. Assessment and evaluation of historic tailing facilities has shown a need for improved monitoring concepts and techniques. In this paper the authors present a new monitoring technique which meets the needs for safe and effective monitoring and can be applied within a smart monitoring concept.[All papers were considered for technical and language appropriateness by the organizing committee.]

description: The outward-pointing principal null direction of the Schwarzschild Riemann tensor is null hypersurface-forming. If the Schwarzschild mass spontaneously jumps across one such hypersurface then the hypersurface is the history of an outgoing light-like shell. The outward-- pointing principal null direction of the Kerr Riemann tensor is asymptotically (in the neighbourhood of future null infinity) null hypersurface-forming. If the Kerr parameters of mass and angular momentum spontaneously jump across one such asymptotic hypersurface then the asymptotic hypersurface is shown to be the history of an outgoing light-like shell and a wire singularity-free spherical impulsive gravitational wave.

description: Mercury's magnetosphere is known to be affected by enhanced ram pressures and magnetic fields inside interplanetary coronal mass ejections (ICMEs). Here we report detailed observations of an ICME compressing Mercury's dayside magnetosphere to the surface. A fast CME launched from the Sun on November 29 2013 impacted first MESSENGER, which was orbiting Mercury, on November 30 and later STEREO-A near 1 AU on December 1. Following the ICME impact, MESSENGER remained in the solar wind as the spacecraft traveled inwards and northwards towards Mercury's surface until it reached and passed its closest approach to the planet (at 371 km altitude) without crossing into the magnetosphere. The magnetospheric crossing finally occurred 1 minute before reaching the planet's nightside at 400 km altitude and 84$^\circ$N latitude, indicating the lack of dayside magnetosphere on this orbit. In addition, the peak magnetic field measured by MESSENGER at this time was 40% above the values measured in the orbits just prior to and after the ICME, a consequence of the magnetospheric compression. Using both a proxy method at Mercury and measurements at STEREO-A, we show that the extremely high ram pressure associated with this ICME was more than high enough to collapse Mercury's weak magnetosphere. As a consequence, the ICME plasma likely interacted with Mercury's surface, evidenced by enhanced sodium ions in the exosphere. The collapse of Mercury's dayside magnetosphere has important implications for the habitability of close-in exoplanets around M dwarf stars, as such events may significantly contribute to planetary atmospheric loss in these systems.

description: Athalia bolivari Dusmet, 1896
A junior subjective synonym of Athalia circularis circularis (Klug, 1815), synonymy by Benson (1962).
Types. Athalia Bolivari (sic!) Dusmet, 1896: 146. Syntype (s) ♂, “Coruña” Lectotype, ♂, hereby designated (MNCN _Ent 82342, MNCN Cat. Tipos Nº 2268, Fig. 08, see also http://dx.doi.org/10.6084/m9.figshare.746925). Type locality: Spain: Coruña.
Discussion. Benson (1962: 365) synonymized A. bolivari with A. circularis. Fitton (1978: IV 5) listed the taxon as valid. Most likely the name was simply wrong formatted and should appear in this paper under circularis as a synonym. Aksoy et al. (1998) mentioned without further explanation larvae of A. bolivari on Capsella bursapastoris. The systematics of Athalia require further investigation. It is not unlikely that several species are currently confused under the name circularis. The type specimen is obviously a melanistic specimen. It is not quite clear if the type locality concerns the city itself, or the province A Coruña.

description: We studied the thermal conduction through a quantum point contact (QPC), defined in GaAs-AlGaAs heterostructure, in the presence of a transverse magnetic field. A shift in the position of thermo-voltage peak is observed with increasing field. The position of the thermo-voltage peak follows the Cutler-Mott relation in the small field regime (B < 0.5 T); it starts diverging from the Cutler-Mott relation in the moderate field regime, where a cubic magnetic field term dominates over the trivial quadratic term; eventually the shift saturates in the large field regime (B > 3.0 T). Our results suggest that additional calibration is necessary when using QPC as thermometry, especially when the transverse magnetic field is applied.

description: In an effort to understand rooting morphology and the long-term potential for upward migration of solutes from tailings of varying geochemical conditions into evapotranspirative cover systems, test pit investigations were conducted in cover systems of varying thicknesses and age in the Southwestern USA. Study results indicate that rooting density is typically uniform throughout the cover system profile and does not exhibit the exponential decay with depth common in undisturbed reference areas. Root propagation was observed into tailings with pH > 4.5. Increased salinity or decreased pH conditions in the cover system were generally limited to the bottom 15 cm of the cover system, directly above the cover/tailing contact. The extent of upward migration and accumulation of solutes in the cover soils varied depending on the tailing geochemical conditions and the cover system depth. In general, cover soils < 30 cm in depth showed greater salinization than cover soils > 60 cm. Increasing tailing acidity generally resulted in decreased pH and increased EC above the tailing/cover contact; covers above tailings with pH > 4 typically did not show accumulation of solutes.

description: Einige Aminosäurederivate des Typs RR'N-CHR"-COOH reagieren mit MoO3 in siedender wässriger Lösung zu Komplexen der Zusammensetzung A. Im Falle des Dimethylaminoessigesters konnte dabei als Zwischenprodukt auch C1 abgefangen werden. Die Verbindungen der Substanzklasse A zeigen das Verhalten der Photochromie. MoCl5 reagiert in wäßrigem System mit Derivaten des Glycins in unübersichtlicher Weise; den dabei entstehenden Verbindungen werden die Strukturformeln D bis H zugeordnet. Es gelang nicht, durch Einsatz silylierter Aminosäuren kovalente Mo-N-Bindungen aufzubauen.
description: Some derivatives of amino acids of the type RR'N-CHR"-COOH react with MoO3 in boiling aqueous solution resulting in complexes of the composition A. In the case of the ethylester of dimethylamino acetic acid it was possible to catch C1 as an intermediate. Compounds of the Type A are sensitive to insolation (photochromatic effects). MoCl5 reacts in aqueous medium with derivatives of glycine in an unmethodical way. We suggest the isolated compounds to have the formulae D to H. Attempts to prepare a Mo-N covalent bond by means of silylated amino acids have not been successful.

description: We present data on multiple production of jets with transverse energies near 20 GeV in p-pbar collisions at Root(s) = 1.8 TeV. QCD calculations in the parton-shower approximation of PYTHIA and HERWIG and the next-to-leading order approximation of JETRAD are compared to the data for one, two, three, and four jet inclusive production. Transverse energy spectra and multiple jet angular and summed transverse-energy distributions are adequately described by the shower approximation while next-to-leading order calculations describe the data poorly.

description: Dieser Aufsatz behandelt Entwurf, Konstruktion, Kenndaten und Betrieb eines Apparates zur Entmagnetisierung mittels Wechselfeldern. Parameter von Solenoiden mit innerem Halbmesser von 12,0 bis 22,2 cm weisen darauf hin, daß Wechselfelder von einigen Tausend Orsted zu erreichen sind mit Benutzung von Leitern großen Querschnitts, weil für die Konstruktion solcher Solenoide der Ohmsche Widerstand maßgebend ist. Gleichförmigkeit des Feldes, Kerngröße, die entwickelte Hochspannung und Temperaturanstieg begrenzen die Möglichkeit der Parameterwahl und erschweren die technische Lösung. Ausführlich wird beschrieben ein Solenoid mit 12,0 cm Kern, das Wechselfelder mit Spitzenwerten von 2000 Orsted entwickeln kann.
Dieses Solenoid ermöglicht die Untersuchung von bestimmter Fossilmagnetisierung in Gesteinen mittels zweier Autotransformatoren, die eine Abminderung des Wechselfeldes erlauben. Der Durchmesser des Solenoidkernes ist groß genug, um das Einsetzen einer Kippeinrichtung zu gestatten, die allgemein benutzt wird, um die Orientation der Gesteinsprobe zu ändern und dadurch die remanente anhysteretische Magnetisierung zu verhindern. Die Einzelteile des Entmagnetisierungsapparates werden der Reihe nach besprochen.
description: This paper deals with the conception, construction, characteristics and operation of an alternating field demagnetizing unit. The parameters of solenoids having internal diameters ranging from 4.7 to 8.7 inches (12,0 to 22,2 cm) show that, in order to obtain alternating fields of some thousands of Orsted, it is necessary to use a conducting wire having a large section because the resistance is the main factor influencing the construction of such solenoids. The uniformity of the field, the size of the core, the high tension created and the increase in temperature narrow the range for the choice of these parameters and increase the technical difficulties in their construction. A solenoid (core = 12,0 cm) capable of creating altemating fields of 2000 Orsted (peak to peak) is described in detail.
With the help of two autotransformers allowing a decrease of the alternating field, this solenoid is used to study paleomagnetic properties of rocks and the behaviour (experimental psychology) of small animals (Bartley white rats, baby rabbits and cats) in alternating fields of relatively high intensity. The diameter of the solenoid core is sufficiently large to allow the insertion of a tumbler used to change the orientation of the rock sample in order to minimize the acquisition of anhysteretic remanent magnetisation. The essential parts of the demagnetizing apparatus are investigated one after the other.

description: The Hubble constant $H_{0}$ and matter density $Ω_{m}$ of the Universe are measured using the latest $γ$-ray attenuation results from Fermi-LAT and Cherenkov telescopes. This methodology is based upon the fact that the extragalactic background light supplies opacity for very high energy photons via photon-photon interaction. The amount of $γ$-ray attenuation along the line of sight depends on the expansion rate and matter content of the Universe. This novel strategy results in a value of $H_{0}=67.4_{-6.2}^{+6.0}$~km~s$^{-1}$~Mpc$^{-1}$ and $Ω_{m}=0.14_{-0.07}^{+0.06}$. These estimates are independent and complementary to those based on the distance ladder, cosmic microwave background (CMB), clustering with weak lensing, and strong lensing data. We also produce a joint likelihood analysis of our results from $γ$ rays and these from more mature methodologies, excluding the CMB, yielding a combined value of $H_{0}=66.6\pm 1.6$~km~s$^{-1}$~Mpc$^{-1}$ and $Ω_{m}=0.29\pm 0.02$.

Noise-induced Input Dependence in a Convective Unstable Dynamical System

Year: 1998
Subjects: subject: Chaotic Dynamics (nlin.CD)

description: Unidirectionally coupled dynamical system is studied by focusing on the input (or boundary) dependence. Due to convective instability, noise at an up-flow is spatially amplified to form an oscillation. The response, given by the down-flow dynamics, shows both analogue and digital changes, where the former is represented by oscillation frequency and the latter by different type of dynamics. The underlying universal mechanism for these changes is clarified by the spatial change of the co-moving Lyapunov exponent, with which the condition for the input dependence is formulated. The mechanism has a remarkable dependence on the noise strength, and works only within its medium range. Relevance of our mechanism to intra-cellular signal dynamics is discussed, by making our dynamics correspond to the auto-catalytic biochemical reaction for the chemical concentration, and the input to the external signal, and the noise to the concentration fluctuation of chemicals.
