description: We formulate the work output and efficiency for linear irreversible heat engines working between a finite-sized hot heat source and an infinite-sized cold heat reservoir until the total system reaches the final thermal equilibrium state with a uniform temperature. We prove that when the heat engines operate at the maximum power under the tight-coupling condition without heat leakage the work output is just half of the exergy, which is known as the maximum available work extracted from a heat source. As a consequence, the corresponding efficiency is also half of its quasistatic counterpart.

description: We study the factorization and resummation of the transverse momentum spectrum of the color sextet and antitriplet scalars produced at the LHC based on soft-collinear effective theory. Compared to Z boson and Higgs production, a soft function is required to account for the soft gluon emission from the final-state colored scalar. The soft function is calculated at the next-to-leading order, and the resummation is performed at the approximate next-to-next-to-leading logarithmic accuracy. The non-perturbative effects and PDF uncertainties are also discussed.

description: Aim: We aim to compute the mass and velocity anisotropy profiles of Abell 2142 and, from there, the pseudo phase--space density profile $Q(r)$ and the density slope - velocity anisotropy $β- γ$ relation, and then to compare them with theoretical expectations. Methods: The mass profiles were obtained by using three techniques based on member galaxy kinematics, namely the caustic method, the method of Dispersion - Kurtosis, and MAMPOSSt. Through the inversion of the Jeans equation, it was possible to compute the velocity anisotropy profiles. Results: The mass profiles, as well as the virial values of mass and radius, computed with the different techniques agree with one another and with the estimates coming from X-ray and weak lensing studies. A concordance mass profile is obtained by averaging the lensing, X-ray, and kinematics determinations. The cluster mass profile is well fitted by an NFW profile with $c=4.0 \pm 0.5$. The population of red and blue galaxies appear to have a different velocity anisotropy configuration, since red galaxies are almost isotropic, while blue galaxies are radially anisotropic, with a weak dependence on radius. The $Q(r)$ profile for the red galaxy population agrees with the theoretical results found in cosmological simulations, suggesting that any bias, relative to the dark matter particles, in velocity dispersion of the red component is independent of radius. The $β- γ$ relation for red galaxies matches the theoretical relation only in the inner region. The deviations might be due to the use of galaxies as tracers of the gravitational potential, unlike the non--collisional tracer used in the theoretical relation.

description: After a short discussion of various random Bogoliubov-de Gennes (BdG) model operators and the associated physics, the Aizenman-Molchanov method is applied to prove Anderson localization in the weak disorder regime for the spectrum in the central gap. This allows to construct random BdG operators which have localized states in an interval centered at zero energy. Furthermore, techniques for the calculation of Chern numbers are reviewed and applied to two non-trivial BdG operators, the p+ip wave and d+id wave superconductors.

description: Firms frequently innovate by recombining knowledge components. Through bringing together diverse scientific or technological concepts, firms can reassemble these extant knowledge components into novel and useful innovations. At the same time, many of the mechanisms firms use to recombine knowledge components carry substantial agency costs. When firms conduct research and development, diversify, hold slack resources, or locate near close competitors, they become vulnerable to misappropriation of investor resources due to opportunistic actions by agents. Using patent citation data from semiconductor firms, we study how firms, which consistently produce high-quality innovations, balance the need for knowledge recombination with the need to protect investors from opportunism. Our results indicate that, consistent with an agency lens, innovative firms operate under a significant debt load. Consistent with the knowledge recombination perspective, however, innovative firms typically engage in multiple activities that lead to innovation via knowledge recombination.

description: This is part one of our study of models of jets with distributed electron acceleration. We present here our assumptions, basic equations, and their solutions for the steady-state electron distribution. We assume the shape of the rate of electron acceleration and the dependencies of its normalization and the magnetic field strength on the height along the jet. Our focus is on the hard spectral state of black-hole binaries, for which we take into account that their typical radio spectra are flat. This appears to require a constant dissipation rate per unit logarithmic length and conservation of the magnetic energy flux. Our electron kinetic equation includes adiabatic and radiative losses and advection, and our photon radiative transfer equation includes synchrotron absorption and emission and Compton emission. Apart from the self-Compton process, we take into account Compton scattering of stellar and accretion photons and absorption of very-high energy gamma-rays by pair production on soft photons. We present a general solution of the kinetic equation with advection and radiative and adiabatic losses and an analytic solution in the case of dominant synchrotron losses in conical jets. In the following paper, we present detailed spectra resulting from our equations as applied to Cyg X-1.

description: In response to national calls to better align physics laboratory courses with the way physicists engage in research, we have developed an epistemology and expectations survey to assess how students perceive the nature of physics experiments in the contexts of laboratory courses and the professional research laboratory. The Colorado Learning Attitudes about Science Survey for Experimental Physics (E-CLASS) evaluates students' epistemology at the beginning and end of a semester. Students respond to paired questions about how they personally perceive doing experiments in laboratory courses and how they perceive an experimental physicist might respond regarding their research. Also, at the end of the semester, the E-CLASS assesses a third dimension of laboratory instruction, students' reflections on their course's expectations for earning a good grade. By basing survey statements on widely embraced learning goals and common critiques of teaching labs, the E-CLASS serves as an assessment tool for lab courses across the undergraduate curriculum and as a tool for physics education research. We present the development, evidence of validation, and initial formative assessment results from a sample that includes 45 classes at 20 institutions. We also discuss feedback from instructors and reflect on the challenges of large-scale online administration and distribution of results.

Orbital motions and the conservation-law/preferred-frame $α_3$ parameter

description: We analytically calculate some orbital effects induced by the Lorentz-invariance/momentum-conservation PPN parameter $α_3$ in a gravitationally bound binary system made of a compact primary orbited by a test particle. We neither restrict ourselves to any particular orbital configuration nor to specific orientations of the primary's spin axis $\boldsymbol{\hatψ}$. We use our results to put preliminary upper bounds on $α_3$ in the weak-field regime by using the latest data from Solar System's planetary dynamics. By linearly combining the supplementary perihelion precessions $Δ\dot\varpi$ of the Earth, Mars and Saturn, determined with the EPM2011 ephemerides, we infer $|α_3|\lesssim 6\times 10^{-10}$. Our result is about 3 orders of magnitude better than the previous weak-field constraints existing in the literature, and of the same order of magnitude of the bound expected from the future BepiColombo mission to Mercury. It is, by construction, independent of the other preferred-frame PPN parameters $α_1,α_2$, both preliminarily constrained down to a $\approx 10^{-6}$ level. The wide pulsar-white dwarf binary PSR J0407+1607 yields a preliminary upper bound on the strong-field version $\hatα_3$ of the Lorentz-invariance/momentum-conservation PPN parameter of the order of $3\times 10^{-17}$. It relies upon certain assumptions on the unknown values of the pulsar's spin axis orientation $\boldsymbol{\hatψ}$, the orbital node $Ω$ and the inclination $I$. Neither the pulsar's proper motion, still undetected, nor a possible value of the pulsar's mass $m_{\rm p}$ up to two solar masses substantially affect our result.

Moreover, some of the known expander-based counterexamples to the original Baum-Connes conjecture become confirming examples for our reformulated conjecture.

title: An assemblage of Picenian bronze objects »from Tarragona« in the Episcopal Museum of Vic (Barcelona / E)

description: Die vorliegende Arbeit befasst sich mit einem Ensemble aus Bronzen, das zu Beginn des 20. Jahrhunderts ins Bischöfliche Museum von Vic einging. Das anfängliche Interesse der Studie war die Zuschreibung der Sammlung zu einem Fund aus der Nähe von Tarragona. Das Ensemble ist auffällig, da es zu einer Gruppe von Schmuck und Tracht vom adriatischen Typ gehört, dessen Chronologie sich zwischen Mitte des 7. und Mitte des 6. Jahrhunderts v. Chr. erstreckt (Phase Picenum IV). Das Fehlen von Daten über die Entdeckung, die Seltenheit von Objekten adriatischen Ursprungs im westlichen Mittelmeer sowie die unterschiedliche Zusammensetzung im Vergleich zu den restlichen zeitgleichen Depots veranlasst zu einer Diskussion und Kritik des Ensembles. Dieses Beispiel weist auf die Notwendigkeit hin, museale Sammlungen zu überprüfen, um neue Infor ma tionen zu erhalten und Problematiken zu beleuchten. In diesem Falle geht es um die ersten italischen Importe im Westen als Vorarbeit für die erforderliche Analyse der italischen Fibeln. Die Studie kommt zu dem Schluss, dass das Depot aus dem Bischöflichen Museum von Vic als ein geschlossenes Ensemble auf dem internationalen Antiquariatsmarkt erworben wurde. Diese Art von Gruppierung entspricht einer gängigen Strategie und Geschäftspraxis für den Verkauf von Materialen aus dem Picenum während des ersten Viertels des 20. Jahrhunderts.
description: The present paper deals with an assemblage of bronze finds, which entered the Episcopal Museum of Vic at the beginning of the 20th century. The original interest of the study was the ascribing of the collection to a find from the neighbourhood of Tarragona. The assemblage is conspicuous, as it belongs to a group of jewellery and costume of the Adriatic type dating chronologically to between the mid-7th and mid-6th century B.C. (Picenum phase IV). The lack of data concerning the discovery, the rarity of objects of Adriatic origins in the western Mediterranean, as well as the different composition in comparison with the other contemporary hoards led to a discussion and critique of the assemblage. This example indicates the necessity of checking museums’ collections, in order to gather information and to illustrate problems. In this case we are dealing with the first Italian imports in the West as preparatory work for the appropriate analysis of the Italian fibulae. The study comes to the conclusion that the depot from the Episcopal Museum of Vic was purchased as a complete assemblage on the international antique market. This type of grouping corresponds to normal strategy and business practice for the selling of finds from the Picenum during the first quarter of the 20th century.

description: Despite the advantages of using seashells in concrete, predictive models have not yet been proposed for this type of concrete. To fill this gap, the present study utilized three distinctive machine learning models (i.e. Artificial neural network (ANN), Multivariate Adaptive Regression Spline (MARS), and M5P Model Tree) to investigate the compressive and tensile strength of seashell containing concrete using records collected from the technical literature. The results indicate that the ANN model outperforms the other developed models with R2 equal to 0.939 and 0.903 for the test dataset of compressive and tensile strength, respectively. Although the developed MARS and M5P models resulted in lower accuracy, they produced reliable predictions. Thus, the proposed models can be used successfully to estimate the mechanical properties of seashell-containing concrete. Also, sensitivity analysis of the best model follows experimental results highlighting the higher impact of cement, water and curing time parameters in all two types of strength. In terms of seashell content, the results confirmed that adding high amounts of the seashell to the concrete decreases its strength, while small amounts can be used without any significant adverse effect on strength parameters.

description: We reconsider perturbative unitarity violation in the standard model Higgs inflation model. We show that the Cutkosky cutting rule implied by perturbative unitarity is fulfilled at one-loop. This is a strong indication that unitarity is restored order by order in perturbation theory. We then resum certain one-loop diagrams and show that the relevant dressed amplitude fulfills the Cutkosky rule exactly. This is an example of the self-healing mechanism. The original Higgs inflation model is thus consistent and does not require any new physics beyond the standard model at least up to the Planck scale.

description: Für die Umwandlung einer rotatorischen in eine translatorische Bewegung gibt es eine Vielzahl von Linearantrieben. Planetenwälzgewindetriebe (PWG) gehören zu den am besten geeigneten Antrieben für Anwendungen, die eine sehr hohe Tragfähigkeit bei maximaler Übersetzung erfordern. Kinematik und Kinetik von Planetenwälzgewindetrieben sind bisher nur punktuell zu wenigen Lastpunkten und Geometrien untersucht. Aufgrund der stark unterschiedlichen Bewegung und Freiheitsgrade der Planeten sind Erkenntnisse über Rollengewindetriebe (RGT) und Planetenrollengewindetriebe (PRGT) kaum übertragbar. Im Rahmen dieser Arbeit wird das Systemwissen über den PWG erweitert und die Auswirkungen verschiedenster Einflussfaktoren aus Anwendung und Geometrie untersucht. Einer der Schwerpunkte der Analyse ist die freie Bewegung der mit einer hohen Anzahl von Freiheitsgraden ausgestattet Planeten. Basierend auf dem Stand der Technik werden Mehrkörpersimulationen erstellt und mit Hilfe von Experimenten validiert. Mit den Simulationen wird der Einfluss verschiedenster Faktoren, wie Vorspannung und Radialspiel, auf den PWG untersucht. Nach der Analyse der Kinematik, Kinetik und der Kräfte zwischen den Körpern werden die Wälzkontakte selbst analysiert, um den Einfluss von Faktoren der Anwendung und der Geometrie zu bewerten. Schließlich werden ausgewählte Faktoren in Experimenten validiert und die Ergebnisse im Vergleich zum Stand der Technik bewertet. Die Analyse der Auswirkungen der Faktoren bis hin zu den Kontakten ermöglicht z.B. die Optimierung der Lebensdauer durch die entsprechende Einstellung der Radialluft und der Vorspannung. Darüber hinaus wird die Bedeutung der Überprüfung der Stabilität von Kräften, Bewegungen, Kontaktkräften und Kontaktpunkten für den PWG nachgewiesen - insbesondere wegen des hohen nichtlinearen Verhaltens.
Mechanism of uniaxial magnetocrystalline anisotropy in transition metal alloys

description: Magnetocrystalline anisotropy in transition metal alloys (FePt, CoPt, FePd, MnAl, MnGa, and FeCo) was studied using first-principles calculations to elucidate its specific mechanism. The tight-binding linear muffin-tin orbital method in the local spin-density approximation was employed to calculate the electronic structure of each compound, and the anisotropy energy was evaluated using the magnetic force theorem and the second-order perturbation theory in terms of spin-orbit interactions. We systematically describe the mechanism of uniaxial magnetocrystalline anisotropy in real materials and present the conditions under which the anisotropy energy can be increased. The large magnetocrystalline anisotropy energy in FePt and CoPt arises from the strong spin-orbit interaction of Pt. In contrast, even though the spin-orbit interaction in MnAl, MnGa, and FeCo is weak, the anisotropy energies of these compounds are comparable to that of FePd. We found that MnAl, MnGa, and FeCo have an electronic structure that is efficient in inducing the magnetocrystalline anisotropy in terms of the selection rule of spin-orbit interaction.

Year: 2024

description: Questo articolo studia se e come un approccio "business-like" sia associato all'evoluzione della filantropia nel tempo in un campione di fondazioni bancarie italiane (FOB). I dati vengono raccolti tramite un questionario indirizzato ai presidenti e agli amministratori delle fondazioni bancarie in due periodi distinti a distanza di cinque anni. I risultati mostrano una correlazione positiva e significativa tra l'implementazione degli strumenti di pianificazione e controllo e una più ampia adozione della filantropia strategica come percepita dai soggetti apicali all'interno delle fondazioni. Inoltre, gli amministratori che apportano competenze manageriali specifiche e ai quali viene proposta un percorso di formazione al momento della nomina hanno maggiore probabilità di percepire miglioramenti nell'azione filantropica. Ulteriori analisi mostrano come al variare della composizione della governance (in particolare quando si procede a sostituire il presidente) l'associazione tra i sistemi di pianificazione e controllo e la filantropia strategica diventa negativa, confermando così il forte ruolo di leadership esercitato dal presidente all'interno delle FOB.

description: The discovery of a 125.5 GeV Higgs with standard model-like couplings and naturalness considerations motivate gauge extensions of the MSSM. We analyse two variants of such an extension and carry out a phenomenological study of regions of the parameter space satisfying current direct and indirect constraints, employing state-of-the art two-loop RGE evolution and GMSB boundary conditions. We find that due to the appearance of non-decoupled D-terms it is possible to obtain a 125.5 GeV Higgs with stops below 2 TeV, while the uncolored sparticles could still lie within reach of the LHC. We compare the contributions of the stop sector and the non-decoupled D-terms to the Higgs mass, and study their effect on the Higgs couplings. We further investigate the nature of the next-to lightest supersymmetric particle, in light of the GMSB motivated searches currently being pursued by ATLAS and CMS.

description: Weak-measurement-based experiments [Kocsis et al., Science 332 (2011) 1170] have shown that, at least for pure states, the average evolution of independent photons in Young's two-slit experiment is in compliance with the trajectories prescribed by the Bohmian formulation of quantum mechanics. But, what happens if the same experiment is repeated assuming that the wave function associated with each particle is different, i.e., in the case of mixed (incoherent) states? This question is investigated here by means of two alternative numerical simulations of Young's experiment, purposely devised to be easily implemented and tested in the laboratory. Contrary to what could be expected a priori, it is found that even for conditions of maximal mixedness or incoherence (total lack of interference fringes), experimental data will render a puzzling and challenging outcome: the average particle trajectories will still display features analogous to those for pure states, i.e., independently of how mixedness arises, the associated dynamics is influenced by both slits at the same time. Physically this simply means that weak measurements are not able to discriminate how mixedness arises in the experiment, since they only provide information about the averaged system dynamics.

description: The aim of this work is to describe the structure of a web application to support EU-funded INFN projects in the process of time tracking and reporting. The system has been designed in the early 2010s, following the growth of the EU-funded projects and the need for a framework to handle consistent reports according to the EU guidelines. One objective of this project is to guarantee and certify a valid distribution of hours declared on EU projects by INFN personnel in consistency with the official INFN clocking system, the scientific project management system and, overall, any signed agreements between the INFN and the founding bodies. The system allows the project participants to declare the hours worked on their projects, detailing their distribution across days, work packages and tasks. Interfaces are provided for Project Managers and Financial Officers to manage a project and monitor its trend. This activity is also supported by the INFN Business Intelligence Service, integrated with this system, to provide comprehensive reports for the upper management.

description: We consider stochastic electro-mechanical dynamics of an overdamped power system in the vicinity of the saddle-node bifurcation associated with the loss of global stability such as voltage collapse or phase angle instability. Fluctuations of the system state vector are driven by random variations of loads and intermittent renewable generation. In the vicinity of collapse the power system experiences so-called phenomenon of critical slowing-down characterized by slowing and simultaneous amplification of the system state vector fluctuations. In generic case of a co-dimension 1 bifurcation corresponding to the threshold of instability it is possible to extract a single mode of the system state vector responsible for this phenomenon. We characterize stochastic fluctuations of the system state vector using the formal perturbative expansion over the lowest (real) eigenvalue of the system power flow Jacobian and verify the resulting expressions for correlation functions of the state vector by direct numerical simulations. We conclude that the onset of critical slowing-down is a good marker of approach to the threshold of global instability. It can be straightforwardly detected from the analysis of single-node autostructure and autocorrelation functions of system state variables and thus does not require full observability of the grid.

description: A magnetic domain wall (DW) behaves as a massive particle with elasticity. Sliding and oscillation of the DW have been observed experimentally, whereas vibration of a width in the DW, "breathing mode", has not been measured so far. We theoretically propose how to observe the breathing mode by the Josephson junction having a ferromagnetic layer between superconducting electrodes. The current-voltage (I-V) curve is calculated by an equivalent circuit of the resistively shunted junction model. The breathing mode is identified by stepwise structures in the I-V curve, which appear at the voltages V=n(hbar/2e)omega with the fundamental constant hbar/e, integer number n, and the frequency of the breathing mode omega.

Transformation devices: carpets in space and space-time

description: Here we extend the theory of space-time or event cloaking into that based on the carpet or ground-plane reflective surface. Further, by recasting and generalizing a scalar acoustic wave model into a new mathematically covariant form, we also show how transformation theories for optics and acoustics can be combined into a single prescription. The single prescription, however, still respects the fundamental differences between electromagnetic and acoustic waves, which then provide us with an existence test for any desired transformation device -- are the required material properties (the required constitutive parameters) physically permitted by the wave theory being designed for? Whilst electromagnetism is a flexible theory permitting almost any transformation device (T-device) design, we show that the acoustic model used here is more restricted.

description: Belidae   Another small and evidently relict family, the Belidae number only about 375 species classified in 38 genera and occur predominantly in the southern hemisphere. They are divided into two subfamilies, Belinae and Oxycoryninae, with rather different distributions and habits. The Belinae, with about 155 species in 25 genera, are restricted to the southern hemisphere, occurring mainly in the Australian region (140 species in 21 genera) but a few also in South America. The Oxycoryninae, with 13 genera and about 200 species, have a worldwide but highly fragmented distribution (Marvaldi et al. 2006). The larvae of Belinae are woodborers in stems and logs, the more primitive Pachyurini and Agnesiotidini (fig. 3) mostly in conifers (Araucariaceae, Podocarpaceae and Cupressaceae) but the Belini in angiosperms, especially acacias in Australia. Oxycoryninae (fig. 4) develop mostly in reproductive plant organs, of gymnosperms (araucarias and cycads) as well as of angiosperms, but also in stems or under bark (see Marvaldi et al. 2006). In Belidae and remaining weevil families, the female rostrum is transformed into a proper oviposition tool by the fusion of labrum and clypeus and the development of more advanced mandibles with long pharyngeal processes, enabling their eggs to be deposited inside firm plant tissues and their larvae to develop truly endophytically.
 The unification of Belinae and Oxycoryninae into a single family is not universally adopted (e.g., Crowson 1955, Thompson 1992, Zimmerman 1994a, Zherikhin & Gratshev 1995), although the close relationship of these two groups has long been recognised and is well supported in phylogenetic analyses (Kuschel 1995, Marvaldi & Morrone 2000, Marvaldi et al. 2002). The Aglycyderini, too, are sometimes treated as a separate subfamily (e.g., May 1993, Kuschel 1995, 2003) or even family (e.g., Thompson 1992, Zimmerman 1994a), but recent phylogenetic analyses (Marvaldi 2005a, Marvaldi et al. 2006) place them firmly inside Oxycoryninae. With phylogenetic analyses recently conducted on all the genera of both Belinae (Kuschel & Leschen 2003) and Oxycoryninae (Marvaldi et al. 2006), the Belidae are the only weevil family for which comprehensive generic phylogenies are available.

description: This article addresses the issue of the closure of the algebra of constraints for generic (cosmological) perturbations when taking into account simultaneously the two main corrections of effective loop quantum cosmology, namely the holonomy and the inverse-volume terms. Previous works on either the holonomy or the inverse volume case are reviewed and generalized. In the inverse-volume case, we point out new possibilities. An anomaly-free solution including both corrections is found for perturbations, and the corresponding equations of motion are derived.

description: Supersymmetric models with a small neutralino-chargino mass difference, and as a result metastable charginos, have been a popular topic of investigation in collider phenomenology, e.g. in anomaly-mediated models of supersymmetry breaking. Recently, the absence of any supersymmetric signal at the 8 TeV LHC data has led to significant interest in the so-called Natural SUSY models with light higgsinos. These models also have a naturally small neutralino-chargino mass difference. However, we show here that when relevant indirect constraints from results at the LHC and elsewhere are applied, this possibility is heavily constrained within the Minimal Supersymmetric Standard Model (MSSM): massive metastable higgsinos are not a signature of Natural SUSY.
