description: The discovery of a 125 GeV Higgs boson at the LHC marked a breakthrough in particle physics. The relative lightness of the new particle inspires the consideration of a high luminosity Circular Electron Positron Collider (CEPC) as a Higgs Factory to study the Higgs boson in a clean environment. At the CEPC, the beamstrahlung might represent one of the most important sources of beam-induced backgrounds that will impact the detector. It will introduce additional backgrounds to the CEPC detector through the subsequent electron-positron pair production and the hadronic process. Therefore its impacts should be carefully evaluated. In this paper, the beamstrahlung-induced backgrounds are first estimated with analytical methods and are further evaluated in detail with Monte Carlo simulation. The detector occupancy due to the beamstrahlung at the location where the first vertex detector layer may be placed is found to be well below 0.5%. Radiation levels characterised as non-ionising energy loss (NIEL) and total ionising dose (TID) are estimated to be ~ $10^{11} 1 $ MeV $ n_{eq}/cm^2/$yr and ~ 300 kRad/yr, respectively.

Subjects: subject: 330 Economics

description: The Fourth Industrial Revolution is changing the world. IT-based technologies start to have an increasing impact on the chemical industry. Incumbents need to smart-up in order to stay competitive. Especially small and medium-sized enterprises (SMEs) are facing a tough challenge as they lack resources and expertise in implementing Industry 4.0. In this paper, the smart-up ecosystem is introduced: a conceptual model that offers SMEs guidance on how they can move, step by step, from an uninformed situation into smart business. Based on initial experiences using the model in practice, some critical points along this smartification journey are highlighted.

description: This article describes two spatially explicit models created to allow experimentation with different societal responses to the COVID-19 pandemic. We outline the work to date on modeling spatially explicit infective diseases and show that there are gaps that remain important to fill. We demonstrate how geographical regions, rather than a single, national approach, are likely to lead to better outcomes for the population. We provide a full account of how our models function, and how they can be used to explore many different aspects of contagion, including: experimenting with different lockdown measures, with connectivity between places, with the tracing of disease clusters, and the use of improved contact tracing and isolation. We provide comprehensive results showing the use of these models in given scenarios, and conclude that explicitly regionalized models for mitigation provide significant advantages over a “one-size-fits-all” approach. We have made our models, and their data, publicly available for others to use in their own locales, with the hope of providing the tools needed for geographers to have a voice during this difficult time.

description: We report ALMA Band 3 observations of CO(6-5), CO(7-6), and [CI](2-1) in B14-65666 (``Big Three Dragons''), one of the brightest Lyman-Break Galaxies at $z>7$ in the rest-frame ultraviolet continuum, far-infrared continuum, and emission lines of [OIII] 88 $μ$m and [CII] 158 $μ$m. CO(6-5), CO(7-6), and [CI](2-1), whose $3σ$ upper limits on the luminosities are approximately 40 times fainter than the [CII] luminosity, are all not detected. The $L_{\rm [CII]}$/$L_{\rm CO(6-5)}$ and $L_{\rm [CII]}$/$L_{\rm CO(7-6)}$ ratios are higher than the typical ratios obtained in dusty star-forming galaxies or quasar host galaxies at similar redshifts, and they may suggest a lower gas density in the photodissociated region in B14-65666. By using the (1) [CII] luminosity, (2) dust mass-to-gas mass ratio, and (3) a dynamical mass estimate, we find that the molecular gas mass ($M_{\rm{mol}}$) is $(0.05-11)\times10^{10}$ $M_{\rm \odot}$. This value is consistent with the upper limit inferred from the nondetection of mid-$J$ CO and [CI](2-1). Despite the large uncertauinty in $M_{\rm mol}$, we estimate a molecular gas-to-stellar mass ratio ($μ_{\rm{gas}}$) of $0.65-140$ and a gas depletion time ($τ_{\rm dep}$) of $2.5-550$ Myr; these values are broadly consistent with those of other high-redshift galaxies. B14-65666 could be an ancestor of a passive galaxy at $z\gtrsim4$ if no gas is fueled from outside the galaxy.

description: Considering that the communication devices (CD) segment only makes up just 7% of the yearly electrical and electronic equipment (EEE) waste, this means that there are no specific CD related sustainable measures, but just EEE generalized solutions. As such, this paper aims at exploring the critical factors for improving the sustainability as well as for the possible implementation of Circular Economy (CE) strategies for the CD segment along their entire supply chain. A wide range of factors pertaining to sustainability in the supply chain especially regarding the electrical and electronic equipment (EEE) market was gotten by means of an elaborate literature analysis. The factors are then compared to the present practices of the revenue leading telecommunications company in Europe, Deutsche Telekom AG (DTAG). From the literature review, we discovered a range of solutions a CD provider such as DTAG can use to improve the sustainability of its CD portfolio over the entire life cycle. These included ensuring that not only the communication company, but all the various suppliers follow sustainable practices such as Green Supply Chain Management or Closed Loop Supply Chain practices, and that they abide to the set of legislations and standardizations already in place for EEE such as REACH, RoHS, ISO 14004 and EPR. Good sustainable practice is also important, including the swapping of the present technologies for more sustainable ones and ensuring that SDGs are meet in the long run. Most of these methods and practices are already being implemented by the DTAG as part of their global strategy. In addition to an insight on the various concepts this industry should follow to ensure adequate implementation of CE, the study further provides suggestions as to strategies which could improve the sustainability of CDs.

description: The Shapley Supercluster Survey is a multi-wavelength survey covering an area of ~23 deg^2 (~260 Mpc^2 at z=0.048) around the supercluster core, including nine Abell and two poor clusters, having redshifts in the range 0.045-0.050. The survey aims to investigate the role of the cluster-scale mass assembly on the evolution of galaxies, mapping the effects of the environment from the cores of the clusters to their outskirts and along the filaments. The optical (ugri) imaging acquired with OmegaCAM on the VLT Survey Telescope is essential to achieve the project goals providing accurate multi-band photometry for the galaxy population down to m*+6. We describe the methodology adopted to construct the optical catalogues and to separate extended and point-like sources. The catalogues reach average 5sigma limiting magnitudes within a 3\arcsec diameter aperture of ugri=[24.4,24.6,24.1,23.3] and are 93% complete down to ugri=[23.8,23.8,23.5,22.0] mag, corresponding to ~m*_r+8.5. The data are highly uniform in terms of observing conditions and all acquired with seeing less than 1.1 arcsec full width at half-maximum. The median seeing in r-band is 0.6 arcsec, corresponding to 0.56 kpc h^{-1}_{70} at z=0.048. While the observations in the u, g and r bands are still ongoing, the i-band observations have been completed, and we present the i-band catalogue over the whole survey area. The latter is released and it will be regularly updated, through the use of the Virtual Observatory tools. This includes 734,319 sources down to i=22.0 mag and it is the first optical homogeneous catalogue at such a depth, covering the central region of the Shapley supercluster.

Evidence of boosted 13CO/12CO ratio in early-type galaxies in dense environments

description: We present observations of $^{13}$CO(1-0) in 17 Combined Array for Research in Millimeter Astronomy (CARMA) Atlas3D early-type galaxies (ETGs), obtained simultaneously with $^{12}$CO(1-0) observations. The $^{13}$CO in six ETGs is sufficiently bright to create images. In these 6 sources, we do not detect any significant radial gradient in the $^{13}$CO/$^{12}$CO ratio between the nucleus and the outlying molecular gas. Using the $^{12}$CO channel maps as 3D masks to stack the $^{13}$CO emission, we are able to detect 15/17 galaxies to $>3σ$ (and 12/17 to at least 5$σ$) significance in a spatially integrated manner. Overall, ETGs show a wide distribution of $^{13}$CO/$^{12}$CO ratios, but Virgo cluster and group galaxies preferentially show a $^{13}$CO/$^{12}$CO ratio about 2 times larger than field galaxies, although this could also be due to a mass dependence, or the CO spatial extent ($R_{\rm CO}/R_{\rm e}$). ETGs whose gas has a morphologically-settled appearance also show boosted $^{13}$CO/$^{12}$CO ratios. We hypothesize that this variation could be caused by (i) the extra enrichment of gas from molecular reprocessing occurring in low-mass stars (boosting the abundance of $^{13}$C to $^{12}$C in the absence of external gas accretion), (ii) much higher pressure being exerted on the midplane gas (by the intracluster medium) in the cluster environment than in isolated galaxies, or (iii) all but the densest molecular gas clumps being stripped as the galaxies fall into the cluster. Further observations of $^{13}$CO in dense environments, particularly of spirals, as well as studies of other isotopologues, should be able to distinguish between these hypotheses.

description: In many organisms, cell division is driven by the constriction of a cytokinetic ring, which consists of actin filaments and crosslinking proteins. While it has long been believed that the constriction is driven by motor proteins, it has recently been discovered that passive crosslinkers that do not turn over fuel are able to generate enough force to constrict actin filament rings. To study the ring constriction dynamics, we develop a model that includes the driving force of crosslinker condensation and the opposing forces of friction and filament bending. We analyze the constriction force as a function of ring topology and crosslinker concentration, and predict forces that are sufficient to constrict an unadorned plasma membrane. Our model also predicts that actin-filament sliding arises from an interplay between filament rotation and crosslinker hopping, producing frictional forces that are low compared to those of crosslinker-mediated microtubule sliding.

description: Image registration is the process of bringing different images into a common coordinate system - a technique widely used in various applications of computer vision, such as remote sensing, image retrieval, and, most commonly, medical imaging. Deep learning based techniques have been applied successfully to tackle various complex medical image processing problems, including medical image registration. Over the years, several image registration techniques have been proposed using deep learning. Deformable image registration techniques such as Voxelmorph have been successful in capturing finer changes and providing smoother deformations. However, Voxelmorph, as well as ICNet and FIRE, do not explicitly encode global dependencies (i.e. the overall anatomical view of the supplied image) and, therefore, cannot track large deformations. In order to tackle the aforementioned problems, this paper extends the Voxelmorph approach in three different ways. To improve the performance in case of small as well as large deformations, supervision of the model at different resolutions has been integrated using a multi-scale UNet. To support the network to learn and encode the minute structural co-relations of the given image-pairs, a self-constructing graph network (SCGNet) has been used as the latent of the multi-scale UNet - which can improve the learning process of the model and help the model to generalise better. And finally, to make the deformations inverse-consistent, cycle consistency loss has been employed. On the task of registration of brain MRIs, the proposed method achieved significant improvements over ANTs and VoxelMorph, obtaining a Dice score of 0.8013 \pm 0.0243 for intramodal and 0.6211 \pm 0.0309 for intermodal, while VoxelMorph achieved 0.7747 \pm 0.0260 and 0.6071 \pm 0.0510, respectively

description: We present a family of high order trapezoidal rule-based quadratures for a class of singular integrals, where the integrand has a point singularity. The singular part of the integrand is expanded in a Taylor series involving terms of increasing smoothness. The quadratures are based on the trapezoidal rule, with the quadrature weights for Cartesian nodes close to the singularity judiciously corrected based on the expansion. High order accuracy can be achieved by utilizing a sufficient number of correction nodes around the singularity to approximate the terms in the series expansion. The derived quadratures are applied to the Implicit Boundary Integral formulation of surface integrals involving the Laplace layer kernels.

description: We present a new zoom-in hydrodynamical simulation, "Erisbh", which follows the cosmological evolution and feedback effects of a supermassive black hole at the center of a Milky Way-type galaxy. ErisBH shares the same initial conditions, resolution, recipes of gas cooling, star formation and feedback, as the close Milky Way-analog "Eris", but it also includes prescriptions for the formation, growth and feedback of supermassive black holes. We find that the galaxy's central black hole grows mainly through mergers with other black holes coming from infalling satellite galaxies. The growth by gas accretion is minimal because very little gas reaches the sub-kiloparsec scales. The final black hole is, at z=0, about 2.6 million solar masses and it sits closely to the position of SgrA* on the MBH-MBulge and MBH-sigma planes, in a location consistent with what observed for pseudobulges. Given the limited growth due to gas accretion, we argue that the mass of the central black hole should be above 10^5 solar masses already at z~8. The effect of AGN feedback on the host galaxy is limited to the very central few hundreds of parsecs. Despite being weak, AGN feedback seems to be responsible for the limited growth of the central bulge with respect to the original Eris, which results in a significantly flatter rotation curve in the inner few kiloparsecs. Moreover, the disk of ErisBH is more prone to instabilities, as its bulge is smaller and its disk larger then Eris. As a result, the disk of ErisBH undergoes a stronger dynamical evolution relative to Eris and around z=0.3 a weak bar grows into a strong bar of a few disk scale lengths in size. The bar triggers a burst of star formation in the inner few hundred parsecs, provides a modest amount of new fuel to the central black hole, and causes the bulge of ErisBH to have, by z=0, a box/peanut morphology.(Abridged)

description: The $Λ$ baryon spectrum is studied within the SU(3) flavor symmetry in a constituent quark model. We found that it is rather difficult to accommodate some negative-parity $Λ$ resonances as single $q^2s$ ($q = u,\,d$ quarks) states in the conventional three-quark picture. The ground $q^3s\bar q$ pentaquark mass spectrum is evaluated and a possible interpretation is proposed in the work: the observed $Λ(1405)1/2^{-}$, $Λ(1670)1/2^{-}$ and $Λ(1800)1/2^{-}$ are three-state mixtures of two $p$-wave $q^2s$ states and one ground $q^3s\bar q$ pentaquark state, so are the $Λ(1520)3/2^{-}$, $Λ(1690)3/2^{-}$ and $Λ(2050)3/2^{-}$ resonances.

description: The task of this European research project (PostMinQuake) is to identify mechanisms, relevant parameters and dependencies causing post-mining seismicity for several European coal regions. When closing an underground coalmine, the mine water raises by stopping mine water pumping, which can lead to micro seismic events due to the final change of the geomechanical stress-regime. The consortium partners (FZN-THGA, GFZ, BRGM, INERIS, CMI, SUT, SRK, IGN, Green Gas, DIAMO) will collect and analyse information from the coal basins Gardanne (France) and Upper Silesia (Czech Republic and Poland). In Germany, we will focus in the Ruhr Basin and Ibbenbüren (North-West Germany), which are places with centuries of hard coal mining history and where mining ceased in 2018. In order to detect the processes that cause micro-seismicity, we are gathering information in the basins regarding geology; mining methods and monitoring protocols; and post-mining situation and seismicity. This information will be analysed to identify similar approaches to develop a synthesis of good practices, compulsory and desired improvements, as well as an post-mining seismicity map for post-mining seismicity diagnosis. We also aim to develop a Ground Motion Prediction Equation, and the elaboration of criteria of hazard rating. The final guideline could help the mining industry and decision-making bodies to manage the risks of post-mining micro seismicity, also of interest in old petroleum reservoirs when used to storage H2 or even for geothermal energy.

title: Mineral inclusions in detrital garnet – An excellent petrogenetic tool

description: Cold and deep subduction is a characteristic feature of modern-style plate tectonics (MSPT) and a prerequisite for the formation of low-temperature/high-pressure (LT/HP) and ultrahigh-pressure (UHP) rocks. Although having strong implications for processes like the movement of materials between surface and mantle, mantle convection, thermal regimes, or the crustal growth rate, the onset of MSPT is poorly understood and controversially debated. One argument for an early onset are local occurrences of Paleoproterozoic retrogressed rocks suggested to have initially formed at LT/HP conditions (e.g., Weller & St-Onge, 2017, Nature Geoscience 10, 305-311). In contrast, a major argument for a late onset is the absence of mineralogical indicators for LT/HP and UHP metamorphism, like glaucophane and coesite, from the pre-Neoproterozoic crystalline rock record (e.g., Stern, 2005, Geology 33, 557-560). A limiting factor for the exploration of LT/HP and UHP rocks through time is the decreasing preservation of crystalline rocks with increasing age. Thus, the sedimentary record represents an important archive that preserves information on ancient continental crust lost due to erosion (e.g., Dhuime et al., 2017, Sedimentary Geology 357, 16-32). Nevertheless, reconstructing metamorphic conditions from a sedimentary perspective is challenging, mainly because we face sand-sized mineral grains that lost their paragenetic context. Here we present a selection of case studies that highlight the applicability of mineral inclusion assemblages in detrital garnet as an excellent petrogenetic indicator. This technique enables to partially reconstruct the paragenetic context and to screen the underexplored sedimentary record for mineralogical evidence supporting the operation of MSPT in deep time.

Dynamical Quantum Phase Transitions in the Kitaev Honeycomb Model

description: The notion of a dynamical quantum phase transition (DQPT) was recently introduced in [Heyl et al., Phys. Rev. Lett. 110, 135704 (2013)] as the non-analytic behavior of the Loschmidt echo at critical times in the thermodynamic limit. In this work the quench dynamics in the ground state sector of the two-dimensional Kitaev honeycomb model are studied regarding the occurrence of DQPTs. For general two-dimensional systems of BCS-type it is demonstrated how the zeros of the Loschmidt echo coalesce to areas in the thermodynamic limit, implying that DQPTs occur as discontinuities in the second derivative. In the Kitaev honeycomb model DQPTs appear after quenches across a phase boundary or within the massless phase. In the 1d limit of the Kitaev honeycomb model it becomes clear that the discontinuity in the higher derivative is intimately related to the higher dimensionality of the non-degenerate model. Moreover, there is a strong connection between the stationary value of the rate function of the Loschmidt echo after long times and the occurrence of DQPTs in this model.

description: Properties of random mixed states of order $N$ distributed uniformly with respect to the Hilbert-Schmidt measure are investigated. We show that for large $N$, due to the concentration of measure, the trace distance between two random states tends to a fixed number ${\tilde D}=1/4+1/π$, which yields the Helstrom bound on their distinguishability. To arrive at this result we apply free random calculus and derive the symmetrized Marchenko--Pastur distribution, which is shown to describe numerical data for the model of two coupled quantum kicked tops. Asymptotic values for the fidelity, Bures and transmission distances between two random states are obtained. Analogous results for quantum relative entropy and Chernoff quantity provide other bounds on the distinguishablity of both states in a multiple measurement setup due to the quantum Sanov theorem.
