description: A methodology for computing the massless spectrum of heterotic vacua with Wilson lines is presented. This is applied to a specific class of vacua with holomorphic SU(5)-bundles over torus-fibered Calabi-Yau threefolds with fundamental group Z_2. These vacua lead to low energy theories with the standard model gauge group SU(3)_C x SU(2)_L x U(1)_Yand three families of quark/leptons. The massless spectrum is computed, including the multiplicity of Higgs doublets.

Motion of Planetesimals in the Hill Sphere of the Star Proxima Centauri

description: The motion of planetesimals initially located in the feeding zone of the planet Proxima Centauri c, at distances of 500 AU from the star to the star's Hill sphere radius of 1200 AU was considered. In the analyzed non-gaseous model, the primary ejection of planetesimals from most of the feeding zone of an almost formed planet c to distances greater than 500 AU from the star occurred during the first 10 million years. Only for planetesimals originally located at the edges of the planet's feeding zone, the fraction of planetesimals that first reached 500 AU over the time greater than 10 million years was more than half. Some planetesimals could reach the outer part of the star's Hill sphere over hundreds of millions of years. Most of the planetesimals that first reached 500 AU from Proxima Centauri first reached 1200 AU from the star in less than 1 million years. In the considered model, the disk of planetesimals in the outer part of the star's Hill sphere was rather flat. The results may be of interest for understanding the motion of bodies in other exoplanetary systems, especially those with a single dominant planet. The strongly inclined orbits of bodies in the outer part of Proxima Centauri's Hill sphere can primarily result from bodies that entered the Hill sphere from outside. The radius of Proxima Centauri's Hill sphere is an order of magnitude smaller than the radius of the outer boundary of the Hills cloud in the Solar System and two orders of magnitude smaller than the radius of the Sun's Hill sphere. Therefore, it is difficult to expect the existence of a similarly massive cloud around this star as the Oort cloud around the Sun.

Rapidity distribution of gluons in the classical field model for heavy ion collisions

description: The rapidity distribution of gluons produced in heavy ion collisions is studied by a numerical computation in 2+1-dimensional classical Yang-Mills theory. By assuming that the classical source strength g^2 mu depends on rapidity as g^4 mu^2 ~ exp(+- lambda y) and studying collisions of two nuclei with different g^2 mu we find that the rapidity distribution of produced gluons at central rapidities is very broad. The transverse energy is seen to decrease even more slowly as a function of y than the multiplicity. We discuss these results and the range in y and sqrt(s) where they are applicable in the light of experimental results and other theoretical calculations.

description: Recent progress from Jefferson Lab has significantly improved our understanding of the nucleon spin structure in the high-$x$ region. Results from two experiments in Hall A are presented. The first experiment is a precision measurement of the neutron spin asymmetry, $A_1^n$, in the high-$x$ (valence quark) region. The results show for the first time that $A_1^n$ becomes positive at large $x$, strongly breaking SU(6) (spin-flavor) symmetry. The data trend is in good agreement with SU(6)-breaking valence quark models and with the fits to the previous world data. Combining the $A_1^n$ results with the world $A_1^p$ data, the up and down quark spins distributions in the nucleon were extracted. The results showed that for the proton the valence down quark spin is in the opposite direction from that of the proton, in disagreement with predictions of leading-order perturbative QCD models, which neglect quark orbital angular momentum. In the second experiment, the $Q^2$ dependence of the moments and sum rules of the spin structure in the low to intermediate $Q^2$ region were measured, providing a unique bridge linking the quark-gluon picture of the nucleon and the coherent hadronic picture.

title: The eruptions of Örӕfajökull 1362 (Iceland) and Lanzarote 1730-36 (Canary Islands) : sulphur emissions and volcanology
Creators: name: Sharma, Kirti
Publisher: name: The Open University
Year: 2005

description: This thesis presents new data on the volcanology, erupted volumes, and sulphur emissions of the AD 1362 Örӕfajökull eruption and the AD 1730-36 Lanzarote eruption, and relates these findings to their atmospheric and environmental impacts. The Örӕfajökull eruption was an explosive Plinian event with high eruption columns (~30 Ian) that produced an extensive tephra-fall and a small pyroclastic flow deposit (~2 km3 total volume). In contrast, the Lanzarote eruption was a long-lasting basaltic fissure eruption involving Hawaiian and Strombolian fire fountain activity (eruption plumes 8-16 km high) generating a scoria fall deposit and lava flows (~5 km3 total volume).

Chapter 1 introduces the effects of volcanic gas release, and highlights the importance of SO2. In chapter 2, I provide a critical assessment of the petrologic method used to estimate the sulphur release from a volcanic eruption. The petrologic method uses the difference in sulphur concentrations between melt inclusions and matrix glasses, measured by electron microprobe, scaled to the mass of erupted magma, and corrected for the magma crystal content. I show that it provides estimates for sulphur degassing from non-arc, basaltic, reduced magmas that are similar to independent satellite measurements (TOMS). Using this technique, the AD 1362 Örӕfajökulll eruption is estimated to have released only ~0.6 Mt of SO2 into the stratosphere - supported by lack of an ice core acidity peak. The major environmental hazard resulting from this eruption was large volumes of pumice and ash injected into the upper atmosphere and its subsequent fallout over a wide area (chapter 3). The Lanzarote eruption released at least 45 Mt of SO2. This was determined using a new technique based on the correlation between S and incompatible element (K, P, Ti) ratios (S/I); knowing this ratio the original S content of a degassed liquid can be calculated from its concentration of I. The release of SO2 from the Lanzarote eruption is shown to have caused significant climatic perturbations - as demonstrated in the climate proxy record (chapter 4).

description: We present Keck/HIRES abundance measurements and metal-line kinematic profiles of the damped Lyman alpha systems (DLAs) towards the quasars Q0933+733 (z_abs=1.479) and Q0948+433 (z_abs=1.233). These two DLAs have among the five highest HI column densities at any redshift: N(HI)=4.2E21 cm^{-2}. The metal-line data, presented here for the first time, reveal that these DLAs are noteworthy for several other reasons as well. 1) The Q0933+733 DLA exhibits simple kinematic structure with unusually narrow velocity widths as measured from its unsaturated metal lines (delta v=16 km/s). At 2.6% solar, it has the second lowest metallicity at z<2. 2) The Q0948+433 DLA has among the strongest metal-line transitions of any known DLA. The saturated SiII1808 line implies a high metallicity ([Si/H]> -1) and a significant alpha-enhancement. The strong metal lines of this DLA have made possible the detection of TiII1910, CoII2012, and MgI2026. 3) We find that the relative gas-phase abundances of both DLAs follow the general trend seen at high redshift, e.g., enhanced Zn/Fe and Si/Fe, and sub-solar Mn/Fe, indicating that there is little evolution in the nucleosynthetic patterns of DLAs down to this epoch. 4) Their high HI column densities imply that these DLAs dominate the column density-weighted cosmic mean metallicity, , of the universe at z<1.5. Using the 15 DLAs with measured metallicities in the redshift interval 0.4 = -0.89^{+0.40}_{-0.33}, where the uncertainties are 95% confidence limits.

Cyclical patterns in profits, provisioning and lending of banks and procyclicality of the new Basel capital requirements

description: The proposed risk sensitive minimum requirements of the new Basel capital accord have raised concerns about possible (acceleration of) procyclical behaviour of banking, which might threaten macroeconomic stability. This article analyses the interaction between business cycles and banks over the past two decades for 26 industrial countries. As expected, profits appear to move up and down with the business cycle, allowing for accumulation of capital in boom periods. Provisioning for credit losses rise when the cycle falls, but less so when net income of banks is relatively high, which reduces procyclicality. Lending fluctuates with the business cycle too, but appears to be driven by demand rather than by supply factors such as (shortage of) capital, which contradicts the assumptions underlying capital crunch theory. All in all, over the last decades, distortion caused by procyclical behaviour of banks has been limited, banking crises excepted. JEL Codes: G21, G28, E32

description: Effective Human-Robot Interaction (HRI) is fundamental to seamlessly integrating robotic systems into our daily lives. However, current communication modes require additional technological interfaces, which can be cumbersome and indirect. This paper presents a novel approach, using direct motion-based communication by moving a robot's end effector. Our strategy enables users to communicate with a robot by using four distinct gestures -- two handshakes ('formal' and 'informal') and two letters ('W' and 'S'). As a proof-of-concept, we conducted a user study with 16 participants, capturing subjective experience ratings and objective data for training machine learning classifiers. Our findings show that the four different gestures performed by moving the robot's end effector can be distinguished with close to 100% accuracy. Our research offers implications for the design of future HRI interfaces, suggesting that motion-based interaction can empower human operators to communicate directly with robots, removing the necessity for additional hardware.

The Temperature Dependence of the QCD Running Coupling

Year: 2004
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: We study the running of the QCD coupling with the momentum squared ($Q^2$) and the temperature scales in the high temperature limit ($T > T_{c}$), using a mass dependent renormalization scheme to build the Renormalization Group Equations. The approach used guaranty gauge invariance, through the use of the Hard Thermal Loop approximation, and independence of the vertex chosen to renormalize the coupling. In general, the dependence of the coupling with the temperature is not logarithmical, although in the region $Q^2 \sim T^2$ the logarithm approximation is reasonable. Finally, as known from Debye screening, color charge is screened in the coupling. The number of flavors, however, is anti-screened.

description: This paper aims to analyze the effects of Italian banking consolidation during the nineties on the efficiency of the financial system, on competition in the market for banking and financial services, and on the reallocation of bank ownership. Whereas a review of the recent theoretical and empirical literature shows that none of these aspects has received an unequivocal solution, an analysis of the Italian case indicates that the banking consolidation processes were accompanied by gains in efficiencyand competitiveness. Consolidation did not, however, offset the increasing distortions in the ownership structure of a large part of the Italian banking groups. JEL Codes: G32, G34, G21

description: Using wide-field HST/WFPC2 imaging and extensive Keck/LRIS spectroscopy, we present a detailed study of the galaxy populations in MS2053--04, a massive, X-ray luminous cluster at z=0.5866. Analysis of 149 confirmed cluster members shows that MS2053 is composed of two structures that are gravitationally bound to each other; their respective velocity dispersions are 865 km/s (113 members) and 282 km/s (36 members). MS2053's total dynamical mass is 1.2x10^15 Msun. MS2053 is a classic Butcher-Oemler cluster with a high fraction of blue members (24%) and an even higher fraction of star-forming members (44%), as determined from their [OII] emission. The number fraction of blue/star-forming galaxies is much higher in the infalling structure than in the main cluster. This result is the most direct evidence to date that the Butcher-Oemler effect is linked to galaxy infall. In terms of their colors, luminosities, estimated internal velocity dispersions, and [OII] equivalent widths, the infalling galaxies are indistinguishable from the field population. MS2053's deficit of S0 galaxies combined with its overabundance of blue spirals implies that many of these late-types will evolve into S0 members. The properties of the blue cluster members in both the main cluster and infalling structure indicate they will evolve into low mass, L3.

description: Topological matter and topological optics have been studied in many systems, with promising applications in materials science and photonics technology. These advances motivate the study of the interaction between topological matter and light, as well as topological protection in light-matter interactions. In this work, we study a waveguide-interfaced topological atom array. The light-matter interaction is nontrivially modified by topology, yielding novel optical phenomena. We find topology-enhanced photon absorption from the waveguide for large Purcell factor, i.e., $Γ/Γ_0\gg 1$, where $Γ$ and $Γ_0$ are the atomic decays to waveguide and environment, respectively. To understand this unconventional photon absorption, we propose a multi-channel scattering approach and study the interaction spectra for edge- and bulk-state channels. We find that, by breaking inversion and time-reversal symmetries, optical anisotropy is enabled for reflection process, but the transmission is isotropic. Through a perturbation analysis of the edge-state channel, we show that the anisotropy in the reflection process originates from the waveguide-mediated non-Hermitian interaction. However, the inversion symmetry in the non-Hermitian interaction makes the transmission isotropic. At a topology-protected atomic spacing, the subradiant edge state exhibits huge anisotropy. Due to the interplay between edge- and bulk-state channels, a large topological bandgap enhances nonreciprocal reflection of photons in the waveguide for weakly broken time-reversal symmetry, i.e., $Γ_0/Γ\ll 1$, producing complete photon absorption. We show that our proposal can be implemented in superconducting quantum circuits. The topology-enhanced photon absorption is useful for quantum detection. This work shows the potential to manipulate light with topological quantum matter.

description: Do deep learning models for instance segmentation generalize to novel objects in a systematic way? For classification, such behavior has been questioned. In this study, we aim to understand if certain design decisions such as framework, architecture or pre-training contribute to the semantic understanding of instance segmentation. To answer this question, we consider a special case of robustness and compare pre-trained models on a challenging benchmark for object-centric, out-of-distribution texture. We do not introduce another method in this work. Instead, we take a step back and evaluate a broad range of existing literature. This includes Cascade and Mask R-CNN, Swin Transformer, BMask, YOLACT(++), DETR, BCNet, SOTR and SOLOv2. We find that YOLACT++, SOTR and SOLOv2 are significantly more robust to out-of-distribution texture than other frameworks. In addition, we show that deeper and dynamic architectures improve robustness whereas training schedules, data augmentation and pre-training have only a minor impact. In summary we evaluate 68 models on 61 versions of MS COCO for a total of 4148 evaluations.

description: The PHENIX experiment has measured mid-rapidity transverse momentum spectra (0.4 < p_T < 4.0 GeV/c) of single electrons as a function of centrality in Au+Au collisions at sqrt(s_NN) = 200 GeV. Contributions to the raw spectra from photon conversions and Dalitz decays of light neutral mesons are measured by introducing a thin (1.7% X_0) converter into the PHENIX acceptance and are statistically removed. The subtracted ``non-photonic'' electron spectra are primarily due to the semi-leptonic decays of hadrons containing heavy quarks (charm and bottom). For all centralities, charm production is found to scale with the nuclear overlap function, T_AA. For minimum-bias collisions the charm cross section per binary collision is N_cc^bar/T_AA = 622 +/- 57 (stat.) +/- 160 (sys.) microbarns.

description: The ever-growing corpus of scientific literature presents significant challenges for researchers with respect to discovery, management, and annotation of relevant publications. Traditional platforms like Semantic Scholar, BibSonomy, and Zotero offer tools for literature management, but largely require manual laborious and error-prone input of tags and metadata. Here, we introduce a novel retrieval augmented generation system that leverages chat-based large language models (LLMs) to streamline and enhance the process of publication management. It provides a unified chat-based interface, enabling intuitive interactions with various backends, including Semantic Scholar, BibSonomy, and the Zotero Webscraper. It supports two main use-cases: (1) Explorative Search & Retrieval - leveraging LLMs to search for and retrieve both specific and general scientific publications, while addressing the challenges of content hallucination and data obsolescence; and (2) Cataloguing & Management - aiding in the organization of personal publication libraries, in this case BibSonomy, by automating the addition of metadata and tags, while facilitating manual edits and updates. We compare our system to different LLM models in three different settings, including a user study, and we can show its advantages in different metrics.

description: Natural hazards have a wide range of impacts, including on factors that are normally unpriced because they are not bought and sold in markets. Key examples include impacts on human health, the environment, ecosystem services and other outcomes relevant to social welfare. Economists seek to quantify these impacts in financial-equivalent terms in order to be able to compare them with market impacts and include them in Benefit: Cost Analysis (BCA) of policies and strategies to mitigate risks. Estimating these so-called non-market values can be difficult. This paper reviews the methods available for doing so, presents a comprehensive list of the non-market values that might be affected by natural hazards and reviews the existing literature that estimates non-market values relevant to natural hazards. We find that there are few applications specifically in a natural hazard context. We conclude with a discussion on the limitations of non-market valuation in the natural hazard context.
Hybrid simulation and its application to the gravity load collapse of reinforced concrete frames
Creators: name: Charlet, Arnaud Yves
Publisher: name: University of British Columbia

description: The structural testing method called hybrid simulation is implemented at the University of British Columbia. A tutorial is presented to assist the user on how to perform hybrid simulation of structural systems using the finite element software OpenSees, the software framework for hybrid simulation OpenFresco and an event-driven predictor-corrector scheme ensuring continuous testing. Geographically distributed hybrid simulation is introduced and distributed tests performed between the University of British Columbia and the University of California, Berkeley, are described. A hybrid simulation test setup is developed to investigate and validate the application of hybrid simulation to the gravity load collapse of reinforced concrete frames. A shear-critical reinforced concrete column loaded through three dynamic actuators constitutes the physical substructure while a nonlinear ductile reinforced concrete frame makes up the numerical substructure within the OpenSees environment. A nonlinear transformation method is implemented to allow for an accurate application of the three-degree-of-freedom loading on the specimen through the three-actuator test setup, and a specific predictor-corrector algorithm with variable actuator speed is designed to ensure smooth continuous testing despite the use of an implicit iterative integration scheme. Furthermore, a methodology using an iterative predictor-corrector algorithm with mode-switch is developed to enable the use of force control for the actuators in combination with a displacement-based finite element analysis engine. Results from the hybrid tests are compared with a shaking table test of the same structure, and are shown to exhibit the same general behaviour: shear and axial load failure of the shear-critical column followed by gravity load redistribution. However, the inability of the analytical model to capture the residual drifts observed in the shake table tests resulted in an underprediction of the drift demand on the system.

description: We investigate the ultraviolet-to-optical spectral energy distributions (SEDs) of 17 active galactic nuclei (AGNs) using quasi-simultaneous spectrophotometry spanning 900-9000 Angstrom (rest frame). We employ data from the Far Ultraviolet Spectroscopic Explorer (FUSE), the Hubble Space Telescope (HST), and the 2.1-meter telescope at Kitt Peak National Observatory (KPNO). Taking advantage of the short-wavelength coverage, we are able to study the so-called "big blue bump," the region where the energy output peaks, in detail. Most objects exhibit a spectral break around 1100 Angstrom. Although this result is formally associated with large uncertainty for some objects, there is strong evidence in the data that the far-ultraviolet spectral region is below the extrapolation of the near-ultraviolet-optical slope, indicating a spectral break around 1100 Angstrom. We compare the behavior of our sample to those of non-LTE thin-disk models covering a range in black-hole mass, Eddington ratio, disk inclination, and other parameters. The distribution of ultraviolet-optical spectral indices redward of the break, and far-ultraviolet indices shortward of the break, are in rough agreement with the models. However, we do not see a correlation between the far-ultraviolet spectral index and the black hole mass, as seen in some accretion disk models. We argue that the observed spectral break is intrinsic to AGNs, although intrinsic reddening as well as Comptonization can strongly affect the far-ultraviolet spectral index. We make our data available online in digital format.

Securities and banking: bridges and walls

description: The paper examines the relationship between banking and securities activities in the light of financial market developments (securitisation, institutionalization of investment, emergence of complex financial instruments, conglomeration and consolidation), with particular reference to Europe. The enhanced links between banking and securities businesses have generated increased and new risks to financial institutions. However, banks' stability remains crucial for the stability of the financial system as a whole, because of their unique role as provider of liquidity. The paper also addresses the implications of the banking-securities combination for regulatory and supervisory arrangements. The exporting of prudential requirements traditional in banking (such as capital ratios) into the securities field, and the importing of securities regulation (such as transparency requirements) into the banking sector, can be deemed mutually beneficial. As regards supervision, there is a need to monitor the continued effectiveness of the current framework. This entails strengthening co-operation both at the national level and on a cross-border basis among sectoral supervisors in the micro-prudential field, and between them and central banks in the macro-prudential field.

title: An investigation of the mechanism of information reduction
Creators: name: Edmunds, Robert

description: Contemporary theories of skill acquisition emphasise qualitative changes in processing as expertise is acquired (Anderson 1981; Cheng 1985; Newell 1990; 1998; Lewis 2001). In particular, describing this qualitative change as a switch from calculating the answer to the retrieval of the solutions from memory, is popular (Campitelli and Gobet, 2005; Logan 1988,2002; Nosofsky & Palmeri, 1997; Palmeri, 1997, 1999). Against this background, Haider and Frensch (1996, 1999a, 1999b, 2002) have recently identified some of the quantitative changes that may also occur with practice, changes which they term Information Reduction (IR). They demonstrated that people could 'reduce' to processing task-relevant segments of a stimulus, without instruction to do so. Further they found this effect was not stimulus-specific, transferring to novel item sets. This latter point was particularly troublesome for any theory reliant on the retrieval of exemplars from memory, since such a strategy will become unsuccessful for novel items. The work presented in this thesis further explored the factors that may playa role in IR. Study 1 both replicated the basic effect and also found reduction when the visual regularity of the stimulus was varied. Study 2 realised a new target search task (TST) in which IR also developed, generalising the strategy beyond the original alphabet arithmetic task (AAT). The third study of the thesis investigated further attributes that could inhibit or facilitate reduction. The final study determined the regularity of task-redundancy necessary for IR to take place. The results are discussed in terms of the residual processing of task irrelevant items and the overall part IR must play in skill acquisition.

description: We review the literature regarding the impact of financial innovation on the monetary transmission mechanism and on the way the central bank can achieve its ultimate goal, that is to control the price level. We argue that, although the form of central bank instruments and current methods for implementing monetary policy may change, the goals that the policy makers try achieve by employing these instruments remain valid, and achievable.

description: This paper presents the third extension to the Very Large Baseline Array (VLBA) Calibrator Survey, containing 360 new sources not previously observed with very long baseline interferometry (VLBI). The survey, based on three 24 hour VLBA observing sessions, fills the areas on the sky above declination -45 degrees where the calibrator density is less than one source within a 4 degrees radius disk at any given direction. The positions were derived from astrometric analysis of the group delays determined at 2.3 and 8.6 GHz frequency bands using the Calc/Solve software package. The VCS3 catalogue of source positions, plots of correlated flux density versus the length of projected baseline, contour plots and fits files of naturally weighted CLEAN images as well as calibrated visibility function files are available on the Web at http://gemini.gsfc.nasa.gov/vcs3

description: This study assesses, from the economic perspective, cost-effectiveness of substitution of variable factors, i.e. mineral fertilisers (SE295), with plant protection products (SE300) in the process of crop production of commercial farms in Poland. The analysis was based on the Cobb-Douglas production function model, which was to analyse substitution of the factors. In 2010, the surveyed sample covered 8,583 and in 2011 – 8,378 commercial farms. From the economic perspective, substitution of mineral fertilisation with plant protection products was beneficial for improvement of crop production efficiency of commercial farms. In 2010, this resulted from three times higher (3.01) rate of transformation of the plant protection product factor into plant bioproduct. In 2011, the ratio amounted to 2.65 to the advantage of plant protection products. The higher the difference between the rates, the higher the economic efficiency of substitution between substitutes.

description: World agriculture faces a serious challenge: how to guarantee a relevant quantitative and health standard of food provision to a growing, and probably increasingly more affluent population, at the same time, reducing – or at least not increasing – the pressure on the environment and climate change. Competition for land, freshwater, energy and mineral resources, necessary to produce potassium and phosphorus fertilisers, will be tougher, as well. However, there are some strategies to meet these challenges. Coordinated and consistent actions are necessary, both on the side of demand (changes in diet and consumption patterns, and reduction in food losses) and supply in agri-food markets. In particular, it is necessary to close the existing yield gaps, improve the efficiency in the use of all resources, invest in research and agricultural implementations, and reduce losses across the entire food chains. Individual actions should be taken simultaneously and on a global scale, which, in itself, poses a serious problem. This instantly brings to mind the climate negotiations: almost everyone agrees that multilateral agreements would maximise the overall well-being, but the temptation to “get a free ride” prevails among many countries, as priorities continue to have short-term objectives and effects.
