description: Previous studies indicate that faint and bright early-type galaxies (ETGs) present different coefficients and dispersion for their Kormendy relation (KR). A recently published paper states that the intrinsic dispersion of the KR depends on the magnitude range within which the galaxies are contained, therefore, we investigate here whether the magnitude range has also an influence over the values of the coefficients of the KR; $α$ (zero point) and $β$ (slope). We perform numerical simulations and analysis of these coefficients for 4 samples of galaxies, which contain an approximate total of 9400 ETGs in a relatively ample magnitude range ($$ $\sim 6 mag$). The analysis of the results makes us conclude that the values of the KR coefficients depend on the width of the magnitude range and the brightness of galaxies within the magnitude range. This dependence is due to the fact that the distribution of galaxies in the $\log (r_{e}) - _{e}$ plane depends on luminosity and that this distribution is not symmetrical, that is, the geometric shape of the distribution of galaxies in the $\log (r_{e}) - _{e}$ plane plays an important role in the determination of the values of the coefficients of the KR.

Subjects: subject: Soft Condensed Matter (cond-mat.soft)

description: Particles that interact via a square-shoulder potential, consisting of an impenetrable hard core with an adjacent, repulsive, step-like corona, are able to self-organize in a surprisingly rich variety of rather unconventional ordered structures. Using optimization strategies that are based on ideas of genetic algorithms we encounter, as we systematically increase the pressure, the following archetypes of aggregates: low-symmetry cluster and columnar phases, followed by lamellar particle arrangements, until at high pressure values compact, high-symmetry lattices emerge. These structures are characterized in the NPT ensemble as configurations of minimum Gibbs free energy. Based on simple considerations, i.e., basically minimizing the number of overlapping coronae while maximizing at the same time the density, the sequence of emerging structures can easily be understood.

Comparing pertinent effects of antiferromagnetic fluctuations in the two and three dimensional Hubbard model

description: We use the dynamical vertex approximation (D$Γ$A) with a Moriyaesque $% λ$ correction for studying the impact of antiferromagnetic fluctuations on the spectral function of the Hubbard model in two and three dimensions. Our results show the suppression of the quasiparticle weight in three dimensions and dramatically stronger impact of spin fluctuations in two dimensions where the pseudogap is formed at low enough temperatures. Even in the presence of the Hubbard subbands, the origin of the pseudogap at weak-to-intermediate coupling is in the splitting of the quasiparticle peak. At stronger coupling (closer to the insulating phase) the splitting of Hubbard subbands is expected instead. The $\mathbf{k}$-dependence of the self energy appears to be also much more pronounced in two dimensions as can be observed in the $\mathbf{k}$-resolved D$Γ$A spectra, experimentally accessible by angular resolved photoemission spectroscopy in layered correlated systems.

Can the $π^+χ_{c1}$ resonance structures be $D^*\bar{D}^*$ and $D_1\bar{D}$ molecules?

description: We use QCD sum rules to study the recently observed resonance-like structures in the $π^+χ_{c1}$ mass distribution, $Z_1^+(4050)$ and $Z_2^+(4250)$, considered as $D^{*+}\bar{D}^{*0}$ and $D_1^+\bar{D}^0+ D^+\bar{D}_1^0$ molecules with the quantum number $J^P=0^+$ and $J^P=1^-$ respectively. We consider the contributions of condensates up to dimension eight and work at leading order in $α_s$. We obtain $m_{D^*D^*}=(4.15\pm0.12) \GeV$, around 100 MeV above the $D^*D^*$ threshold, and $m_{D_1D}=(4.19\pm 0.22) \GeV$, around 100 MeV below the $D_1D$ threshold. We conclude that the $D^{*+}\bar{D}^{*0}$ state is probably a virtual state that is not related with the $Z_1^+(4050)$ resonance-like structure. In the case of the $D_1D$ molecular state, considering the errors, its mass is consistent with both $Z_1^+(4050)$ and $Z_2^+(4250)$ resonance-like structures. Therefore, we conclude that no definite conclusion can be drawn for this state from the present analysis.

description: The thermal multihadron production observed in different high energy collisions poses two basic problems: (1) why do even elementary collisions with comparatively few secondaries (e+e- annihilation) show thermal behaviour, and 2) why is there in such interactions a suppression of strange particle production? We show that the recently proposed mechanism of thermal hadron production through Hawking-Unruh radiation can naturally account for both. The event horizon of colour confinement leads to thermal behaviour, but the resulting temperature depends on the strange quark content of the produced hadrons, causing a deviation from full equilibrium and hence a suppression of strange particle production. We apply the resulting formalism to multihadron production in e+e- annihilation over a wide energy range and make a comprehensive analysis of the data in the conventional statistical hadronization model and the modified Hawking-Unruh formulation. We show that this formulation provides a very good description of the measured hadronic abundances, fully determined in terms of the string tension and the bare strange quark mass; it contains no adjustable parameters.

Proper Motions and Brightness Variations of Nonthermal X-ray Filaments in the Cassiopeia A Supernova Remnant

description: We present Chandra ACIS X-ray observations of the Galactic supernova remnant Cassiopeia A taken in December 2007. Combining these data with previous archival Chandra observations taken in 2000, 2002, and 2004, we estimate the remnant's forward shock velocity at various points around the outermost shell to range between 4200 and 5200 +/- 500 km/s. Using these results together with previous analyses of Cas A's X-ray emission, we present a model for the evolution of Cas A and find that it's expansion is well fit by a rho_ej ~ r^{-(7-9)} ejecta profile running into a circumstellar wind. We further find that while the position of the reverse shock in this model is consistent with that measured in the X-rays, in order to match the forward shock velocity and radius we had to assume that ~ 30% of the explosion energy has gone into accelerating cosmic rays at the forward shock. The new X-ray images also show that brightness variations can occur for some forward shock filaments like that seen for several nonthermal filaments seen projected in the interior of the remnant. Spectral fits to exterior forward shock filaments and interior nonthermal filaments show that they exhibit similar spectra. This together with similar flux variations suggests that interior nonthermal filaments might be simply forward shock filaments seen in projection and not located at the reverse shock as has been recently proposed.

description: The rapid experimental progress in the field of superconducting nanocircuits gives rise to an increasing quest for advanced quantum-control techniques for these macroscopically coherent systems. Here we demonstrate theoretically that stimulated Raman adiabatic passage (STIRAP), a well-established method in quantum optics, should be possible with the quantronium setup of a Cooper-pair box. We find the parameters which optimize the procedure and show how the scheme appears to be robust against decoherence and should be realizable even with the existing technology.

description: A time series of soft X-ray emission observed on 1974-2007 years (GOES) is analyzed. We show that in the periods of high solar activity 1977-1981, 1988-1992, 1999-2003 the energy statistics of soft X-ray solar flares for class M and C is well described by a FARIMA time series with Pareto innovations. The model is characterized by two effects. One of them is a long-range dependence (long-term memory), and another corresponds to heavy-tailed distributions. Their parameters are statistically stable enough during the periods. However, when the solar activity tends to minimum, they change essentially. We discuss possible causes of this evolution and suggest a statistical model for predicting the flare energy statistics.

Seismic response of retaining structures
Creators: name: Salgado, Francisco Manuel Goncalves Alves
Publisher: name: University of British Columbia
Year: 2010

description: A simple method of analyses which allows both the earthquake induced forces and displacements of retaining structures to be computed is presented. The method considers both the weight of the wall and the flexibility and strength of both the backfill and foundation soil. A single degree of freedom perfect elastic-plastic model is used and the equation of motion is integrated to yield the time histories of wall force and displacement. The method is applied to a gravity retaining wall structure subjected to three different acceleration time histories. The results indicate that: (1) the dynamic displacements will be small for walls having the usual factor of safety against sliding > 1.5; (2) the maximum dynamic force on the wall increases as the factor of safety against sliding increases and can be greater than the Mononobe-Okabe value when sliding is prevented from occurring.
The circumbinary rings of GG Carinae: indications of disc eccentricity growth in the B[e] supergiant's atomic emission lines

description: B[e] supergiants have unusual circumstellar environments which may include thin, concentric rings displaying atomic line emission. GG Carinae is a B[e] supergiant binary which exhibits such a geometry in its circumbinary environment. We study atomic emission lines arising from GG Carinae's circumbinary disc in FEROS spectra collected between 1998 and 2015. We find that semi-forbidden Fe\,II] and permitted Ca\,II emission are formed in the same thin circumbinary ring previously reported to have forbidden [O\,I] and [Ca\,II] emission. We find that there are two circumbinary rings orbiting with projected velocities of $84.6\pm1.0$\,km\,s$^{-1}$ and $27.3\pm0.6$\,km\,s$^{-1}$. Deprojecting these velocities from the line-of-sight, and using updated binary masses presented by \cite{Porter2021GGPhotometry}, we find that the radii of the circumbinary rings are $2.8^{+0.9}_{-1.1}$\,AU and $27^{+9}_{-10}$\,AU for the inner ring and outer ring respectively. We find evidence of subtle dynamical change in the inner circumbinary ring over the 17 years spanned by the data, manifesting in variability in the ratio of the intensity of the blueshifted peak to the redshifted peak of its emission lines and the central velocity becoming more blueshifted. We perform smoothed-particle hydrodynamic simulations of the system which suggest that these observed changes are consistent with pumping of the eccentricity of a radially thin circumbinary ring by the inner binary. We find a systemic velocity of the GG Carinae system of $-23.2 \pm 0.4$\,km\,s$^{-1}$.

description: We consider the semiclassical quantization of sine-Gordon solitons on the circle with periodic and anti-periodic boundary conditions. The 1-loop quantum corrections to the mass of the solitons are determined using zeta function regularization in the integral representation. We compare the semiclassical results with exact numerical calculations in the literature and find excellent agreement even outside the plain semiclassical regime.

description: There is growing evidence that digital peer-support networks can have a positive influence on behaviour change and wellbeing outcomes for people who harm themselves and others. However, making and sustaining such networks are subject to ethical and pragmatic challenges, particularly for perpetrators of domestic violence whom pose unique risks when brought together. In this work we report on a ten-month study where we worked with six support workers and eighteen perpetrators in the design and deployment of Fragments of the Past; a socio-material system that connects audio messages with tangible artefacts. We share how crafting digitally-augmented artefacts - 'fragments' - of experiences of desisting from violence can translate messages for motivation and rapport between peers, without subjecting the process to risks inherent with direct inter-personal communication. These insights provide the basis for practical considerations for future network design with challenging populations.

On the scarcity of redshifted OH and millimetre-band molecular absorption
Creators: name: Curran, S. J.
Publisher: name: arXiv
Year: 2021
Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)
subject: FOS: Physical sciences

description: Despite much searching, redshifted decimetre and millimetre-band absorption by molecular gas remains very rare, limited to just six systems at z > 0.05. Detection of these transitions can yield precise diagnostics of the conditions of the star forming gas in the earlier Universe, the hydroxyl (OH) radical being of particular interest as in the 18-cm ground state there are four different transitions located close to HI 21-cm and thus detectable with the Square Kilometre Array and its pathfinders. The four transitions of OH have very different dependences on the fundamental constants, thus having much potential in testing for any evolution in these over large look-back times. By collating the photometry in a uniform manner, we confirm our previous hypothesis that the normalised OH absorption strength is correlated with the optical--near-infrared red colour of the sight-line. Applying this to the published searches, we find that all, but one (J0414+054), have simply not been searched sufficiently deeply. We suggest that this is due to the standard selection of sources with reliable optical redshifts introducing a bias against those with enough dust with which to shield the molecular gas. For the single source searched to sufficient depth, we have reason to suspect that the high degree of reddening arises from another system along the sight-line, thus not being inconsistent with our hypothesis. We also show that the same optical redshift bias can account for the scarcity of millimetre-band absorption.

Role of "Intrinsic Charm" in Semi-Leptonic B-Meson Decays

description: We discuss the role of so-called "intrinsic-charm" operators in semi-leptonic B-meson decays, which appear first at order 1/m_b^3 in the heavy quark expansion. We show by explicit calculation that -- at scales mu <= m_c -- the contributions from "intrinsic-charm" effects can be absorbed into short-distance coefficient functions multiplying, for instance, the Darwin term. Then, the only remnant of "intrinsic charm" are logarithms of the form ln(m_c^2/m_b^2), which can be resummed by using renormalization-group techniques. As long as the dynamics at the charm-quark scale is perturbative, alpha_s(m_c) << 1, this implies that no additional non-perturbative matrix elements aside from the Darwin and the spin-orbit term have to be introduced at order 1/m_b^3. Hence, no sources for additional hadronic uncertainties have to be taken into account. Similar arguments may be made for higher orders in the 1/m_b expansion.

description: En se basant sur les données d’un testing mené en France, ce policy brief montre comment l’organisation du recrutement affecte la discrimination ethnique à l’embauche. Notre échantillon est constitué de grandes entreprises multi-établissements, au sein desquelles nous distinguons deux types d’organisation du recrutement : le recrutement effectué par un service RH centralisé au niveau de l’entreprise et le recrutement effectué uniquement au niveau de l’établissement, généralement par des managers. Nos résultats indiquent que le passage par un service centralisé diminue de façon significative le niveau de discrimination dans les suites données aux candidatures : par rapport au recrutement organisé localement, on observe une diminution de l’écart du taux de rappel entre les candidats ayant des noms à consonance « hexagonale » et ceux ayant un nom à consonance “maghrébine”. Cette étude montre qu’agir sur l’organisation des recrutements dans les grandes entreprises peut être envisagé comme un outil relativement efficace de lutte contre les discriminations à l’embauche lors de la première étape du recrutement.
description: Based on an original correspondence study in France, this policy brief assesses how the organization of recruitment in large companies affects ethnic discrimination. We consider large multi-establishment companies and distinguish two types of organization of recruitment: hiring carried out by a human resources department at a centralized level of the company and hiring conducted only at the level of the establishment concerned by the position, generally by managers in charge of recruitment. Our results indicate that access to a centralized HR department in the selection of applications has an important effect on the level of discrimination, i.e., this type of organization of recruitment results in a significant decrease in the probability that applicants with native-sounding names are solely selected. This study shows that acting on the organization of recruitment in large companies can be seen as an efficient tool against hiring discrimination at the first stage of recruitment.

Περιλαμβάνουν χώρους υποδοχής, όπως αίθουσες υποδοχής (ρεσεψιόν), χώρους παραμονής, εστίασης, αναψυχής και διανυκτέρευσης πελατών. Τα ξενοδοχεία υπόκεινται σε ελέγχους από τον Ε.Ο.Τ. που αφορούν τη σκοπιμότητα-καταλληλότητα του οικοπέδου, την έγκριση των αρχιτεκτονικών σχεδίων και την άδεια λειτουργίας των μονάδων, χορηγούμενη επίσης από τον Ε.Ο.Τ. Καινοτομία ονομάζεται το σύνολο των κοινωνικών και οικονομικών αλλαγών που συντελούνται στις ξενοδοχειακές επιχειρήσεις, με στόχο τη βελτίωση της ποιότητας των προϊόντων και υπηρεσιών τους, αλλά και της φήμης προς τους πελάτες τους. Με λίγα λόγια, όταν εφαρμόζεται η καινοτομική διαδικασία μέσα σε μια επιχείρηση, εισέρχονται και δημιουργούνται μέσα σε αυτή νέες μέθοδοι, αντιλήψεις, ιδέες, τεχνικές και συστήματα. Οι καινοτομίες που εφαρμόζονται από ξενοδοχείο σε ξενοδοχείο και από εταιρεία σε εταιρεία είναι διαφορετικές μεταξύ τους. Επιπλέον, τα ξενοδοχεία συνηθίζουν να προάγουν καινοτομίες, με στόχο να αυξήσουν την αποδοτικότητά τους, να αποδείξουν πως έχουν δυνατότητες να κάνουν καινούρια πράγματα, αλλά και για να εξελίξουν περαιτέρω το ανθρώπινο δυναμικό τους. Ένα ξενοδοχείο χρειάζεται να ξεκινήσει να καινοτομεί, με το να δημιουργεί νέα προϊόντα . Τα ξενοδοχεία μπορούν να αποκτήσουν καινούρια προϊόντα και υπηρεσίες μέσα από εξαγορές, δηλαδή με το να αγοράζουν μία επιχείρηση ή με το να παράγουν το προϊόν κάποιου άλλου. Ανταγωνισμός γενικά ονομάζεται ο αγώνας ανάμεσα σε οργανισμούς, επιχειρήσεις και χώρες, με σκοπό την επίλυση των στόχων τους. Υπάρχουν τέσσερα διαγνωστικά τμήματα σε μια ανάλυση ανταγωνιστών, που είναι οι μελλοντικοί στόχοι, η τρέχουσα στρατηγική, οι υποθέσεις και οι ικανότητες. Σε ένα ανταγωνιστικό περιβάλλον, η κίνηση της μιας επιχείρησης εξαρτάται από τις κινήσεις των υπόλοιπων 11 επιχειρήσεων. Για την ενίσχυση του ανταγωνισμού μεταξύ των ξενοδοχειακών επιχειρήσεων μέσα από την καινοτομία , απαιτείται η ύπαρξη κατάλληλου προσωπικού μέσα σε αυτές, ενός καλώς διαμορφωμένου χώρου, αλλά και η ιδανική οργάνωσή τους. Κρίνεται ιδιαίτερα σημαντικό για τις επιχειρήσεις να αναπτύσσουν νέα προϊόντα και υπηρεσίες ολοένα και περισσότερο, εξαιτίας του μικρού κύκλου ζωής που αυτά έχουν. Ο τρόπος με τον οποίο μπορούν τα ξενοδοχεία να ενισχύσουν την ανταγωνιστικότητά τους μέσα από την καινοτομία, είναι να διαθέτουν εξειδικευμένους υπαλλήλους , ένα κατάλληλα εκπαιδευμένο προσωπικό και να προχωράνε κάθε φορά σε καινοτομίες, οι οποίες και να ανταποκρίνονται στις απαιτήσεις των πελατών τους.

description: A laboratory scale study was undertaken to investigate the possibility of removing "enhanced" amounts of phosphorus from municipal wastewater using solely biological means. The system consisted of an anaerobic-aerobic treatment sequence. Several modifications were studied to observe their effect on the capability of the system to remove phosphorus. These included temperature changes and the addition of a sludge conditioning reactor to minimize nitrate input to the anaerobic reactor and thus eliminating the possible interference with the release of phosphorus in this reactor and the subsequent uptake in the aerobic reactor. Parameters such as COD, MLSS, DO, ORP, nitrates, nitrites, TKN, pH, alkalinity, and heavy metals were monitored throughout the study in addition to the determination of orthophosphates and total phosphates. The results show that nitrification activity, once established in the aerobic reactor, was extremely difficult to curtail due to the small scale effects. The denitrification of the return sludge in the sludge conditioning reactor did not in itself result in the manifestation of "enhanced" phosphorus removal by the system. It is hypothesized that excellent phosphorus removal (up to 98%) can be obtained using essentially an anaerobic-aerobic treatment scheme only when the system is operated at exceptionally long sludge ages (approximately 86 days in this study).

description: We give examples over arbitrary fields of rings of invariants that are not finitely generated. The group involved can be as small as three copies of the additive group, as in Mukai's examples over the complex numbers. The failure of finite generation comes from certain elliptic fibrations or abelian surface fibrations having positive Mordell-Weil rank. Our work suggests a generalization of the Morrison-Kawamata cone conjecture from Calabi-Yau varieties to klt Calabi-Yau pairs. We prove the conjecture in dimension 2 in the case of minimal rational elliptic surfaces.

description: We analyze the production and subsequent decay of the neutral Higgs bosons of the MSSM into electrically neutral quark pairs qq'=bs,tc of different flavors at the LHC and compare with the direct FCNC production mechanisms. The cross-sections are computed in the unconstrained MSSM with minimal flavor-mixing sources and taking into account the stringent bounds from radiative B-meson decays. We extend the results previously found for these FCNC processes, which are singularly uncommon in the SM. Specifically, we report here on the SUSY-EW contribution of the Higgs-mediated FCNC cross-section into bs and tc final states and the SUSY-QCD and SUSY-EW contributions to bs-production. In this way, the complete map of MSSM predictions for the qq'-pairs produced at the LHC becomes available. The upshot is that the most favorable channels are: 1) the Higgs boson FCNC decays into bs, and 2) the direct production of tc pairs, both of them at the 1 pb level and mediated by SUSY-QCD effects. If, however, the latter are suppressed, we find a small SUSY-EW yield for the tc-production through Higgs decays but, at the same time, a cross-section of 0.1-1 pb for bs-production, which implies a significant number (10^4-10^5) of bs-pairs per 100 inverse femtobarn of integrated luminosity.

description: DNNs are becoming less and less over-parametrised due to recent advances in efficient model design, through careful hand-crafted or NAS-based methods. Relying on the fact that not all inputs require the same amount of computation to yield a confident prediction, adaptive inference is gaining attention as a prominent approach for pushing the limits of efficient deployment. Particularly, early-exit networks comprise an emerging direction for tailoring the computation depth of each input sample at runtime, offering complementary performance gains to other efficiency optimisations. In this paper, we decompose the design methodology of early-exit networks to its key components and survey the recent advances in each one of them. We also position early-exiting against other efficient inference solutions and provide our insights on the current challenges and most promising future directions for research in the field.

Improving durability of bridge decks by transverse prestressing
Creators: name: Poston, R. W.
Publisher: name: The University of Texas at Austin
Year: 1984
Subjects: subject: Bridges--Floors

description: The principal objective of the study was to examine the concept of improving bridge deck design by the application of transverse prestressing and to specifically examine the improvement of durability due to protection from chloride-induced corrosion. The secondary objective was to provide structural design related recommendations for proper use of modern prestressing systems to ensure effective distribution of transverse prestress throughout deck slabs. To fulfill these objectives, the research was divided into three areas. The first area was the durability phase, in which the primary emphasis was the experimental investigation of prestressed concrete specimens exposed to an aggressive chloride environment. The second area was the structural phase in which both experimental and analytical studies were conducted to investigate the structural aspects of transverse prestressing. The final phase was the formulation of design recommendations for transverse prestressing which incorporated the findings from the structural and durability studies. The results from the durability study indicate that current specifications for the design of reinforced concrete decks which implicitly permit crack widths under service loads of 0.011 in. are inadequate for protection of steel reinforcement from chloride-induced corrosion. Transverse prestressing is effective in reducing corrosion because it permits a "crack-free" slab under service loads. However, to reduce the risk of corrosion from long-time exposure to an aggressive chloride-containing environment, a minimum concrete cover of about 2.5 in. over steel reinforcement and a maximum water-cement ratio of 0.45 in the concrete is needed. In addition, special attention must be given to the prestressing system to ensure full encapsulation and thus prevent penetration of aggressive corrosion-producing substances. The results from the structural study indicate that diaphragms have a significant effect on the distribution of stress in transversely prestressed bridge decks. To overcome the effects of diaphragms on transverse stress distribution, either the diaphragm can be prestressed or additional transverse prestressing in the deck slab over diaphragm regions can be used. The results from the design recommendation study indicate that transverse prestressing represents a viable and economical alternative for improving the durability of bridge decks. The proposed design recommendations should provide for a corrosion- and frost-resistant crack-free deck slab. The simplified procedures which were developed for determining slab and diaphragm forces required to overcome restraining effects should ensure effective distribution of transverse prestress throughout deck slabs

The shape of a diagram will depend on the authors’ and/or scribes’ intentions and proficiency, as well as on the expectations of their audience(s). It will also depend on whether and to what level diagrams are meant to convey plain transmission/reproduction and/or innovation in the content or in the purpose of the work. One of the ways in which these transformations can be approached is by scanning the path the “archetypal” shape took trough the hands of different copyists, at different times and in different places, deriving a tentative “visual stemmatology” from it.

description: X-ray Quasi-Periodic Eruptions (QPEs) are a recently discovered phenomenon associated with supermassive black holes at the centers of galaxies. They are high amplitude soft X-ray flares that recur on timescales of hours, but what causes these flares remains uncertain. In the two years since their original discovery, four known QPE-hosting galaxies have been found, with varying properties and levels of activity. We have conducted a blind algorithm-assisted search of the XMM-Newton Source Catalog and found a fifth QPE candidate, XMMSL1 J024916.6-041244. This is a star-forming galaxy hosting a relatively low-mass nuclear black hole, and has previously been identified as a Tidal Disruption Event candidate. An XMM-Newton pointed observation of the source in 2006 exhibited nearly two QPE-like flares in soft X-rays, and, unlike in other QPE sources, there are hints of corresponding dips in the UV light curves. Afterwards, a series of Swift observations observed the rapid dimming of the source; thereafter, in August 2021, we triggered a second XMM-Newton observation, which revealed that the source is detected, but the QPEs are no longer present. Here we report on (I) the strategy we used to systematically search through XMM-Newton archival data; (II) the properties of J0249 and its QPE flares; and (III) the relative behaviors and properties of the QPE sample to date, now 5 members large.

description: We consider a class of multi-component hybrid inflation models whose evolution may be analytically solved under the slow-roll approximation. We call it multi-brid inflation (or $n$-brid inflation where $n$ stands for the number of inflaton fields). As an explicit example, we consider a two-brid inflation model, in which the inflaton potentials are of exponential type and a waterfall field that terminates inflation has the standard quartic potential with two minima. Using the $δN$ formalism, we derive an expression for the curvature perturbation valid to full nonlinear order. Then we give an explicit expression for the curvature perturbation to second order in the inflaton perturbation. We find that the final form of the curvature perturbation depends crucially on how the inflation ends. Using this expression, we present closed analytical expressions for the spectrum of the curvature perturbation ${\cal P}_{S}(k)$, the spectral index $n_S$, the tensor to scalar ratio $r$, and the non-Gaussian parameter $f_{NL}^{\rm local}$, in terms of the model parameters. We find that a wide range of the parameter space $(n_S, r, f_{NL}^{\rm local})$ can be covered by varying the model parameters within a physically reasonable range. In particular, for plausible values of the model parameters, we may have large non-Gaussianity $f_{NL}^{\rm local}\sim 10$--100. This is in sharp contrast to the case of single-field hybrid inflation in which these parameters are tightly constrained.

description: A programmable quantum current generator based on the application of Ohm's law to quantum voltage and resistance standards has demonstrated a realization of the ampere from the elementary charge with a $10^{-8}$ relative uncertainty [J. Brun-Picard et al. PRX 6, 041051, 2016]. Here, we report on improvements of the device leading to a noise reduction of the generated quantized current. The improved quantum current generator is used to calibrate different ammeters with lower measurement uncertainties. Besides, measurements of its quantized current using a calibrated Ultrastable Low-Noise Current Amplifier (ULCA) have shown that the realizations of the ampere at PTB (Physikalisch-Technische Bundesanstalt) and LNE (Laboratoire national de métrologie et d'essais) in the range $\pm50$ $μ$A agreed to -3.7 parts in $10^{7}$ with a combined standard uncertainty of 3.1 parts in $10^{7}$ (coverage factor $k_\mathrm{c}=1$).

description: The COVID-19 pandemic induced demand and supply shocks simultaneously and caused major disruptions
in global trade flows and supply chains. To help better understand the ongoing economic impact of the
COVID-19 pandemic, this paper provides a qualitative analysis of selected manufacturing and services
industries that have been significantly affected by the pandemic. It discusses industry trends through 2020
and the first three quarters of 2021 to the extent the information and data are available, the issues in
related global supply chains if applicable, as well as the implications on the road to recovery. This paper
primarily pulls data from international organizations and industry associations, supplemented with
information from major media reports. This collection of industry-based analyses complements the other
working paper simultaneously produced by Erika Bethmann, Emma Blair, Chang Hong, Lin Jones, Chris
Montgomery, Huyen Nguyen— “Regional Macroeconomic and Trade Trends During the COVID-19
Pandemic,” which provides a collection of region-based macroeconomic and trade analyses. Together,
these two papers aim to provide a set of background information and data for future modeling work on
the impact of the COVID-19 pandemic.
