description: We use resonant inelastic x-ray scattering (RIXS) at the Cu L$_3$ edge to measure the charge and spin excitations in the "half-stuffed" Cu--O planes of the cuprate antiferromagnet Ba$_2$Cu$_3$O$_4$Cl$_2$. The RIXS line shape reveals distinct contributions to the $dd$ excitations from the two structurally inequivalent Cu sites, which have different out-of-plane coordinations. The low-energy response exhibits magnetic excitations. We find a spin-wave branch whose dispersion follows the symmetry of a CuO$_2$ sublattice, similar to the case of the "fully-stuffed" planes of tetragonal CuO (T-CuO). Its bandwidth is closer to that of a typical cuprate material, such as Sr$_2$CuO$_2$Cl$_2$, than it is to that of T-CuO. We interpret this result as arising from the absence of the effective four-spin inter-sublattice interactions that act to reduce the bandwidth in T-CuO.

description: We define a policy system to be a collection of hardware, software, communication technologies, persons, procedures, protocols, and standards driven by and for the purpose of advancing a public organization’s mission in regard to policy analysis, planning, and program evaluation decisions. While policy systems already exist in practice, we believe that they have not been identified and studied as a separate, distinguishable area of information systems. They have components and patterns of use that could benefit governments of all levels in carrying out policy making. We propose principles for building policy systems, identify their components, discuss how they address the complexities of policy making, illustrate them with several examples including our own policy system built for a local government agency, and distinguish them from related systems such as management information systems, decision support systems, and collaboratories.
Deploying a Pilot Spectrum Connection Service over GARR/GEANT: Lessons Learned
Creators: name: Vuagnin, Gloria
Publisher: name: Zenodo
Year: 2023

description: Several National Research and Education Networks (NRENs) are currently implementing new generations of optical networks based on partially disaggregated designs. These systems have the capability to transparently transport any optical signal, which opens up the possibility of deploying Spectrum Connection Services (SCS) that can provide ultra high-capacity connections. GARR and GEANT have recently built a pilot SCS between the High Energy Physics Data Centre at CERN in Switzerland and the Italian Tier 1 at CNAF in Bologna. The service has been tested over a distance of 1000km and supports two wavelengths of 400G capacity, this is the first time such a multi-domain spectrum service has been provided to a big-science user.In this presentation, we will discuss the results of this pilot project and highlight its underlying benefits. We will also share our architectural considerations, tips, and tricks for deploying this type of service. Specifically, we will discuss the potential for cost saving when deploying an SCS. Additionally, we will explore the lower latency that can be achieved through router and transponder bypass.

description: We study the effect of the shape anisotropy on the magnetic domain configurations of a ferromagnetic semiconductor (Ga,Mn)As/GaAs(001) epitaxial wire as a function of temperature. Using magnetoresistance measurements, we deduce the magnetic configurations and estimate the relative strength of the shape anisotropy compared with the intrinsic anisotropies. Since the intrinsic anisotropy is found to show a stronger temperature dependence than the shape anisotropy, the effect of the shape anisotropy on the magnetic domain configuration is relatively enhanced with increasing temperature. This information about the shape anisotropy provides a practical means of designing nanostructured spin electronic devices using (Ga,Mn)As.

description: We report calculations indicating the presence of a surface magnetic moment for Rh(001), motivated by the detection of a finite moment by magnetic linear dichroism experiments. We show that, while the density functional with the local density or generalized gradient approximations (LDA and GGA) for exchange and correlation yields a non-magnetic ground state, the application of the GGA plus on-site Coulomb interaction U method predicts surface magnetism, thus offering a solution to the long-standing discrepancy between experiment and theory. The calculated moment on the outermost Rh atom increases with the strength of the effective on-site parameter Ueff=U-J, for Ueff>=1.2 eV, and is as large as 1.24 mu_B for Ueff=2.5 eV.

description: Solar energy generation requires efficient monitoring and management in moving towards technologies for net-zero energy buildings. This paper presents a dependable control system based on the Internet of Things (IoT) to control and manage the energy flow of renewable energy collected by solar panels within a microgrid. Data for optimal control include not only measurements from local sensors but also meteorological information retrieved in real-time from online sources. For system fault tolerance across the whole distributed control system featuring multiple controllers, dependable controllers are developed to control and optimise the tracking performance of photovoltaic arrays to maximally capture solar radiation and maintain system resilience and reliability in real time despite failures of one or more redundant controllers due to a problem with communication, hardware or cybersecurity. Experimental results have been obtained to evaluate the validity of the proposed approach.

description: Homicides in the United States, which disproportionately involve firearms, remain more common than in most other developed nations, despite the substantial decline in lethal violence observed in America during the 1990’s. Can police patrols that are dedicated to reducing illegal gun carrying help reduce gun violence? Based on an article published by the Brookings Institution (Cohen & Ludwig 2003), this brief reports on an evaluation of a 1998 Pittsburgh policing patrol program focused on illegal gun carrying in high-crime areas during the highest-risk periods. The results of this evaluation are consistent with the idea that additional police patrols targeted against illegal gun carrying may yield substantial reductions in gun violence. The Pittsburgh policing program focused on illegally carried firearms in two of the city’s highest crime areas during the peak crime periods of 8pm to midnight, Wednesday through Saturday. The additional five-officer, three-vehicle targeted patrols represented a 25 to 50 percent increase in patrol officers in these high-crime communities. The analysis suggests that the patrols contributed to as much as a 71% decline in hospital-treated assault-related gunshot injuries. No citizen complaints were filed against the Pittsburgh police as a result of the new directed-patrol program. If our evaluation results are correct, directed police patrols against illegal gun carrying may be a very cost-effective way to reduce gun violence. The $35,000 cost of supporting the additional police patrols may yield benefits to the citizens of Pittsburgh from fewer gunshot injuries that are worth as much as $25 million.

description: In heavy ion collisions resonances can create strong non-Gaussian effects in the 2-pion correlation data. Hence, the commonly used Gaussian fit parameters do not fully characterize these correlators. We suggest a different set of HBT parameters which does not presuppose a particular shape of the correlator and allows to extract additional (non-Gaussian) information. Within a simple model for an expanding source including resonance decays it is shown that this additional information provides a clean distinction between scenarios with and without transverse flow.

description: For a renormalizability proof of perturbative models in the Epstein--Glaser scheme with string-localized quantum fields, one needs to know what freedom one has in the definition of time-ordered products of the interaction Lagrangian. This paper provides a first step in that direction. The basic issue is the presence of an open set of $n$-tuples of strings which cannot be chronologically ordered. We resolve it by showing that almost all such string configurations can be dissected into finitely many pieces which can indeed be chronologically ordered. This fixes the time-ordered products of linear field factors outside a nullset of string configurations. (The extension across the nullset, as well as the definition of time-ordered products of Wick monomials, will be discussed elsewhere.)

description: This paper provides geographic information system (GIS) methods and empirical models to forecast point demand for home-delivered goods. A point forecast consists of stops on a street network, including demand at each stop. The purpose of the forecast is to support a network optimization model, based on the traveling salesman problem, to locate one or more new facilities in a region. We illustrate our approach with a case study of home-delivered meals (meals on wheels) in Allegheny County, Pennsylvania.

description: Hundreds of candidate hybrid pulsators of intermediate type A-F were revealed by the recent space missions. Hybrid pulsators allow to study the full stellar interiors, where p- and g-modes are simultaneously excited. The true hybrid stars must be identified since other processes, due to stellar multiplicity or rotation, might explain the presence of (some) low frequencies observed in their periodograms. We measured the radial velocities of 50 candidate Delta Sct - Gamma Dor hybrid stars from the Kepler mission with the Hermes/Ace spectrographs over a span of months to years. We aim to derive the fraction of binary and multiple systems and to provide an independent and homogeneous determination of the atmospheric properties and vsini for all targets. The objective is to identify the physical cause of the low frequencies. We computed 1-D cross-correlation functions (CCFs) in order to find the best parameters in terms of the number of components, spectral type and vsini for each target. Radial velocities were measured from spectrum synthesis and by using a 2-D cross-correlation technique in the case of double- and triple-lined systems. Fundamental parameters were determined by fitting (composite) synthetic spectra to the normalised median spectra corrected for the appropriate Doppler shifts. We report on the analysis of 478 high-resolution Hermes and 41 Ace spectra of A/F-type candidate hybrid pulsators from the Kepler field. We determined their radial velocities, projected rotational velocities, atmospheric properties and classified our targets based on the shape of the CCFs and the temporal behaviour of the radial velocities. We derived orbital solutions for seven new systems. Three long-period preliminary orbital solutions are confirmed by a photometric time-delay analysis. Finally, we determined a global multiplicity fraction of 27% in our sample of candidate hybrid stars.

Extensive numerical calculations are presented in a diagram depicting the drift velocity as a function of a wide range of the driving parameter values. We also present some theoretical considerations which explain some features of the mentioned diagram. In particular, we proof the existence of regions in the driving parameter space with bounded particle motion possessing zero current. Moreover, we present an explicit analytical expression for the drift velocity in the adiabatic limit.

description: I show that off-shell effects, like antisymmetrization and Be-7 distortions, can significantly influence the energy dependence of the nonresonant Be7(p,gamma)B8 astrophysical S factor at higher energies. The proper treatment of these effects results in a vitrually flat E1 component of the S factor at E_cm = 0.3-1.5 MeV energies in the present eight-body model. The energy dependence of the nonresonant S factor, predicted by the present model, is in agreement with the low-energy direct capture data and the existing high-energy Coulomb dissociation data. Irrespective of whether or not the present energy dependence is correct, off-shell effects can cause 15--20% changes in the value of S(0) extrapolated from high-energy (E_cm > 0.7 MeV) data.

description: This essay develops and links two models of ownership: first a composition model of the dimensions comprising ownership in firms, and a content model specifying the societal, firm, and individual factors that give rise to workers’ motivation to participate in ownership and employers’ motivation to share ownership. Ownership comprises financial participation, including control over residual assets, access to marginal revenues, participation in decision making, and access to financial information; along with sociopsychological factors including social standing, social responsibility, and psychological ownership. Firm ownership, across financial and sociopsychological facets, is increasingly parcelled out among financial investors, managers and workers. This new distribution of ownership is particularly characteristic of high technology and start up firms, due to the mobility of highly skilled workers, and their consequent power in the employment relationship. We specify how societal factors, firm characteristics, and worker qualities impact the motivation to own and the motivation to share ownership. By focusing on the shifting power balance of highly mobile workers, this treatment of emerging ownership practices provides a theoretical basis for understanding the employment relationship in start ups and high technological firms.

description: We describe a device (adapter) for off-axis guiding and photometric calibration of wide-angle spectrographs operating in the prime focus of the 6-m telescope of the Special Astrophysical Observatory of the Russian Academy of Sciences. To compensate coma in off-axis star images an achromatic lens corrector is used, which ensures maintaining image quality (FWHM) at a level of about 1'' within 15' from the optical axis. The device has two 54'-diameter movable guiding fields, which can move in 10' x 4'.5 rectangular areas. The device can perform automatic search for guiding stars, use them to control the variations of atmospheric transmittance, and focus the telescope during exposure. The limiting magnitude of potential guiding stars is mR ~17 mag. The calibration path whose optical arrangement meets the telecentrism condition allows the spectrograph to be illuminated both by a source of line spectrum (a He-Ne-Ar filled lamp) and by a source of continuum spectrum. The latter is usually represented either by a halogen lamp or a set of light-emitting diodes, which provide illumination of approximately uniform intensity over the wavelength interval from 350 to 900 nm. The adapter is used for observations with SCORPIO-2 multimode focal reducer.

description: This study aims to describe the longitudinal trajectory of opioid prescribing at the practice level and assess associated factors, including Health Boards and socioeconomic status. This drug utilization research used practice-level dispensing data from 2016 to 2018. Practice-level prescription opioids dispensed were quantified by the defined daily doses (DDDs) per 1000 registrants. Group-based trajectory models were used to identify groups of practices with similar trajectories based on the difference in monthly opioid utilization. Characteristics of registrants were associated with the trajectory by a conditional logistic regression and the prescription opioids dispensed by a random-effect regression model. Of the 798 practices, 29.5% increased opioid prescription by an additional 100 DDDs/1000 registrants/month during 2017 and 2018. Practice in southwest Scotland tended to be categorized into the group with increasing opioid utilization. Deprived socioeconomic status was associated with increasing opioid utilization (odds ratio: 2.2; 95% confidence interval: 1.5, 3.2) or higher annual opioid utilization (coefficient: 358.2; 95% confidence interval: 327.6, 388.8). Increasing opioid utilization over time was related to deprived socioeconomic status associated with chronic pain conditions and inequality in pain services. Further strategies to balance inequality are needed, which needs further investigation.

description: The Coronavirus (COVID-19) pandemic and the ensuing policy responses disrupted how consumers in the United States acquired food away from home, and little is known about how they continued to access these goods. This report summarizes national-level trends in dollars U.S. consumers spent from December 2019–February 2020 through April–June 2022 at quick- and full-service restaurants by service mode (on-premise, drive-thru, delivery, and carry-out) and acquisition and ordering method. Results show that while on-premises (eating inside a restaurant) spending fell at quick- and full-service restaurants, spending at full-service restaurants remained much lower than pre-pandemic spending levels. USDA, Economic Research Service researchers found that consumers quickly adapted to other service modes, like delivery or drive-thru, and this offset many of the losses observed in spending at quick-service restaurants. The authors also observed that consumers increased spending via cell phone apps for carry-out and delivery orders at both types of restaurants relative to pre-pandemic spending. In short, while consumers’ restaurant spending largely returned to pre-pandemic levels, many of the ways that consumers interacted with quick- and full-service restaurants immediately following the onset of the pandemic remained.
description: The authors relied on proprietary data from The NPD Group, a U.S.-based market research provider that gathered information each month from consumer surveys on FAFH acquisition habits that span December 2019–February 2020 through April–June 2022, the most recent available data. The authors examined estimates of changes in spending for QSRs and FSRs by service mode and acquisition methods. The authors also used the U.S. Bureau of Labor Statistics Consumer Price Index to provide estimates in real terms (i.e., inflation adjusted), rather than nominal.

description: The physician market is being transformed in dramatic ways. One of the most notable areas of change has been tremendous growth in physician networks, such as independent practice associations (IPAs). As of August 1996, there were approximately 4,000 IPAs with an average of 300 physicians each, up from approximately 1,500 in 1990. Physician networks are made up of otherwise independent physicians that join together to market themselves collectively to health insurers, and in some cases, directly to employers. Normally, independent competitors are not allowed to set prices jointly. The key question here is whether these networks represent an efficient response to the changing structure of health care markets or strategic attempts to increase market power.

Delta functions on symmetric group algebras are replaced by the corresponding objects (canonical trace functions) for Hecke algebras. The role of the Schur-Weyl duality between unitary groups and symmetric groups is now played by q-deformed Schur-Weyl duality of quantum groups. The appearance of Euler characters of configuration spaces of Riemann surfaces in the expansion persists. We discuss the geometrical meaning of these formulae.

description: Black phosphorus (BP) is an emerging two-dimensional semiconducting material with great potential for nanoelectronic and nanophotonic applications, especially owing to its unique anisotropic electrical and optical properties. Many theoretical studies have predicted the anisotropic optical properties of BP, but the direct experimental quantification remains challenging. The difficulties stem from the ease of BP's degradation when exposed to air in ambient conditions, and from the indirect nature of conventional approaches that are subject to large measurement uncertainties. This work reports a direct investigation of the birefringent optical constants of micrometer-thick BP samples with picosecond (ps) interferometry, over the wavelength range from 780 to 890 nm. In this ps-interferometry approach, an ultrathin (5 nm) platinum layer for launching acoustic waves naturally protects the BP flake from degradation. The birefringent optical constants of BP for light polarization along the two primary crystalline orientations, zigzag and armchair, are directly obtained via fitting the attenuated Brillouin scattering signals. A bi-exponential model is further proposed to analyze the BS signals for a random incident light polarization. The BP experimental results and the associated measurement sensitivity analysis demonstrate the reliability and accuracy of the ps-interferometry approach for capturing the polarization-dependent optical properties of birefringent materials.

description: Observations of energetic neutral atoms (ENAs) are a fruitful tool for remote diagnosis of the plasma in the heliosphere and its vicinity. So far, instruments detecting ENAs from the heliosphere were configured for observations of hydrogen atoms. Here, we estimate emissions of ENAs of the heavy chemical elements helium, oxygen, nitrogen, and neon. A large portion of the heliospheric ENAs is created in the inner heliosheath from neutralized interstellar pick-up ions (PUIs). We modeled this process and calculated full-sky intensities of ENAs for energies 0.2-130 keV/nuc. We found that the largest fluxes among considered species are expected for helium, smaller for oxygen and nitrogen, and smallest for neon. The obtained intensities are 50-10^6 times smaller than the hydrogen ENA intensities observed by IBEX. The detection of heavy ENAs will be possible if a future ENA detector is equipped with the capability to measure the masses of observed atoms. Because of different reaction cross-sections among the different species, observations of heavy ENAs can allow for a better understanding of global structure of the heliosphere as well as the transport and energization of PUIs in the heliosphere.

description: Online communities, which have become an integral part of the day-to-day life of people and organizations, exhibit much diversity in both size and activity level; some communities grow to a massive scale and thrive, whereas others remain small, and even wither. In spite of the important role of these proliferating communities, there is limited empirical evidence that identifies the dominant factors underlying their dynamics. Using data collected from seven large online platforms, we observe a universal relationship between online community size and its activity: First, three distinct activity regimes exist, one of low-activity and two of high-activity. Further, we find a sharp activity phase transition at a critical community size that marks the shift between the first and the second regime. Essentially, it is around this critical size that sustainable interactive communities emerge. Finally, above a higher characteristic size, community activity reaches and remains at a constant and high level to form the third regime. We propose that the sharp activity phase transition and the regime structure stem from the branching property of online interactions. Branching results in the emergence of multiplicative growth of the interactions above certain community sizes.

description: We consider the problem of stability of anti-de Sitter spacetime in five dimensions under small purely gravitational perturbations satisfying the cohomogeneity-two biaxial Bianchi IX ansatz. In analogy to spherically symmetric scalar perturbations, we observe numerically a black hole formation on the time-scale $\mathcal{O}(\varepsilon^{-2})$, where $\varepsilon$ is the size of the perturbation.

description: We investigate the possibility to control localization properties of the asymptotic state of an open quantum system with a tunable synthetic dissipation. The control mechanism relies on the matching between properties of dissipative operators, acting on neighboring sites and specified by a single control parameter, and the spatial phase structure of eigenstates of the system Hamiltonian. As a result, the latter coincide (or near coincide) with the dark states of the operators. In a disorder-free Hamiltonian with a flat band, one can either obtain a localized asymptotic state or populate whole flat and/or dispersive bands, depending on the value of the control parameter. In a disordered Anderson system, the asymptotic state can be localized anywhere in the spectrum of the Hamiltonian. The dissipative control is robust with respect to an additional local dephasing.

description: In the present Letter we present an analytical and numerical solution of the self-consistent mode-coupling equations for the problem of heat conductivity in one-dimensional systems. Such a solution leads us to propose a different scenario to accomodate the known results obtained so far for this problem. More precisely, we conjecture that the universality class is determined by the leading order of the nonlinear interaction potential. Moreover, our analysis allows us determining the memory kernel, whose expression puts on a more firm basis the previously conjectured connection between anomalous heat conductivity and anomalous diffusion.

description: An ever increasing number of configuration parameters are provided to system users. But many users have used one configuration setting across different workloads, leaving untapped the performance potential of systems. A good configuration setting can greatly improve the performance of a deployed system under certain workloads. But with tens or hundreds of parameters, it becomes a highly costly task to decide which configuration setting leads to the best performance. While such task requires the strong expertise in both the system and the application, users commonly lack such expertise. To help users tap the performance potential of systems, we present BestConfig, a system for automatically finding a best configuration setting within a resource limit for a deployed system under a given application workload. BestConfig is designed with an extensible architecture to automate the configuration tuning for general systems. To tune system configurations within a resource limit, we propose the divide-and-diverge sampling method and the recursive bound-and-search algorithm. BestConfig can improve the throughput of Tomcat by 75%, that of Cassandra by 63%, that of MySQL by 430%, and reduce the running time of Hive join job by about 50% and that of Spark join job by about 80%, solely by configuration adjustment.

description: The construction sector is one of the most significant contributors to global CO₂ emissions, accounting for approximately 37% of energy- and processing-related carbon dioxide emissions worldwide (UNEP, 2022). As the industry seeks to reduce its environmental impact, bio-based materials are emerging as a promising solution for more sustainable construction sector. Certification plays a critical role in this transformation, providing a robust framework for validating the sustainability, performance, and environmental credentials of these innovative bio-based materials.This informative event organised by the EU-research project 3-CO and BioReCer, was held on 25 February 2025, at 13:00 CEST. Itexplored the broad landscape of bio-based materials and their diverse applications. The webinar will cover crucial aspects of sustainable construction, including:

The importance of certification for bio-based products,Sustainable building design, conception, and planning,Material recommendations,Building passports as tools for capturing and communicating building data, material composition, and environmental performance,Circularity indicators and their role in assessing a building’s sustainability, including the new ISO 59040 standard for Product Circularity Data Sheets, which emphasises circular concepts such as design for disassembly.Different assessment methods for sustainability of buildings and for constructions, including the Quality Seal for Sustainable Buildings (QNG), e.g., CO₂-footprint for buildings.This is the presentation held by Hein van Tuijl, head of EPEA Benelux. EPEA has been at the forefront of developint the revised ISO 59040 trying to establish effective cirularity indicators in products and certification.
Peer Effects in Sexual Initiation: Separating Demand and Supply Mechanisms

description: Most work on social interactions studies a single, composite effect of interactions within a group. Yet in the case of sexual initiation there are two distinct social mechanisms— peer-group norms and partner availability—with separate effects and different potential interventions. Here I develop an equilibrium search and matching model for first sexual partners that specifies distinct roles for these two mechanisms as part of demand and supply. I estimate the model using a national sample of high school students, with data over time on individual virginity status. The results indicate that peer-group norms have a large effect on the timing of sexual initiation for both boys and girls. Changes in opposite-gender search behavior (i.e., partner availability) also have a large impact on initiation rates for boys, but not for girls.
Kinetics of heat flux avalanches at the first order transition in La(Fe-Mn-Si)$_{13}$-H$_{1.65}$ compounds

description: We study heat flux avalanches occurring at the first order transition in La(Fe-Mn-Si)$_{13}$-H$_{1.65}$ magnetocaloric material. As the transition is associated to the phase boundaries motion that gives rise to the latent heat, we develop a non equilibrium thermodynamic model. By comparing the model with experimental calorimetry data available for Mn=0.18, we find the values of the intrinsic kinetic parameter $R_L$, expressing the damping for the moving boundary interface, at different magnetic fields. We conclude that by increasing field, thus approaching the critical point, the avalanches increase in number and their kinetics is slowed down.

description: Spathulina sicula Rondani, 1856
ORIGINAL DESCRIPTION: 1856: 113.
 TYPE LOCALITY: “ in Sicilia [Sicily (Italy)]” (Rondani 1871c: 168).
 TYPE MATERIAL: 1 ♀, holotype (very dirty) (MZUF: Box 33): Spathulina Rnd. / sicula Rnd., Sicil. / 1729.
 CURRENT STATUS: valid species (Foote 1984: 124, Belcari et al. 1995b: 11, Norrbom et al. 1999: 208).
 REMARKS: Rondani’s (1856: 113) key for the genus Spathulina Rondani, 1856 lists Spathulina sicula as its type species, but he did not provide a detailed description, type locality, number or sex of the specimens. In his redescription Rondani (1871c: 168) specified having a single female: “ Foeminam unicam in Sicilia captam a Ghiliani, olim Clar. Spinola mihi transmisit [Mr. Spinola formerly sent to me a single female collected in Sicilia by Ghiliani]”. We consider the single MZUF female as the holotype (I.C.Z.N. 1999: Articles 72.4.1.1 and 73.1.2).
