description: The recently-synthesized iridate $β$-Li$_2$IrO$_3$ has been proposed as a candidate to display novel magnetic behavior stabilized by frustration effects from bond-dependent, anisotropic interactions (Kitaev model) on a three-dimensional "hyperhoneycomb" lattice. Here we report a combined study using neutron powder diffraction and magnetic resonant x-ray diffraction to solve the complete magnetic structure. We find a complex, incommensurate magnetic order with non-coplanar and counter-rotating Ir moments, which surprisingly shares many of its features with the related structural polytype "stripyhoneycomb" $γ$-Li$_2$IrO$_3$, where dominant Kitaev interactions have been invoked to explain the stability of the observed magnetic structure. The similarities of behavior between those two structural polytypes, which have different global lattice topologies but the same local connectivity, is strongly suggestive that the same magnetic interactions and the same underlying mechanism governs the stability of the magnetic order in both materials, indicating that both $β$- and $γ$-Li$_2$IrO$_3$ are strong candidates to realize dominant Kitaev interactions in a solid state material.

surgical factors

description: Currently, there is limited data addressing surgical factors that contribute to unplanned intubations (UIs). The American College of Surgeons (ACS) National Surgical Quality Improvement Program (NSQIP) defines UIs as a circumstance that requires the unanticipated placement of an endotracheal tube or similar device, such as the laryngeal mask airway (LMA) or nasotracheal tube with ventilatory support, intraoperatively or within 30 days following surgery. Research shows that UIs are associated with elevated rates of patient mortality. This project’s primary aim was to provide a secondary analysis of the NSQIP dataset to determine correlation between UIs and specific surgical factors based on current literature. Data from the NSQIP dataset were examined between 2017 and 2019 to provide the most recent information while minimizing the influence of COVID-related effects. Choice of variables was based on findings from the literature review. This study should serve as a guide for future, more extensive investigations to guide practice.

description: Man-made artificial graphene has attracted significant attention in the past few years due to the possibilities to construct designer Dirac fermions with unexpected topological properties and applications in nanoelectronics. Here we use a first-principles approach within density-functional theory to study molecular graphene similar to the experiment by Gomes~{\em et al.}, Nature {\bf 483}, 306 (2012). The system comprises carbon monoxide molecules arranged on a copper (111) surface in such a way that a hexagonal lattice is obtained with the characteristic electronic properties of graphene. Our results show in detail how carbon monoxide molecules modify the copper surface (and regions beneath) and create a hexagonal lattice of accumulated electrons between the adsorbate molecules. We also demonstrate how the properties of the formed Dirac fermions change as the CO density is tuned, and provide a direct comparison with experimental scanning tunneling microscope images.

description: This paper develops a method for forecasting a nonstationary time series, such as GDP, using a set of high-dimensional panel data as predictors. To this end, we use what is known as a factor augmented regression [FAR] model that contains a small number of estimated factors as predictors; the factors are estimated using time series data on a large number of potential predictors. The validity of this method for forecasting has been established when all the variables are stationary and also when they are all nonstationary, but not when they consist of a mixture of stationary and nonstationary ones. This paper fills this gap. More specifically, we develop a method for constructing an asymptotically valid prediction interval using the FAR model when the predictors include a mixture of stationary and nonstationary factors; we refer to this as mixture-FAR model. This topic is important because typically time series data on a large number of economic variables is likely to contain a mixture of stationary and nonstationary variables. In a simulation study, we observed that the mixture-FAR performed better than its competitor that requires all the variables to be nonstationary. As an empirical illustration, we evaluated the aforementioned methods for forecasting the nonstationary variables, GDP and Industrial Production [IP], using the quarterly panel data on US macroeconomic variables, known as FRED-D. We observed that the mixture-FAR model proposed in this paper performed better than its aforementioned competitors.

description: Analysis of radio signals from cosmic-ray induced air showers has been shown to be a reliable method to extract shower parameters such as primary energy and depth of shower maximum. The required detailed air shower simulations take 1 to 3 days of CPU time per shower for a few hundred antennas. With nearly $60,000$ antennas envisioned to be used for air shower studies at the Square Kilometre Array (SKA), simulating all of these would come at unreasonable costs. We present an interpolation algorithm to reconstruct the full pulse time series at any position in the radio footprint, from a set of antennas simulated on a polar grid. Relying on Fourier series representations and cubic splines, it significantly improves on existing linear methods. We show that simulating about 200 antennas is sufficient for high-precision analysis in the SKA era, including e.g. interferometry which relies on accurate pulse shapes and timings. We therefore propose the interpolation algorithm and its implementation as a useful extension of radio simulation codes, to limit computational effort while retaining accuracy.

description: A method of determining the temperature of the nonradiative reservoir in a microcavity exciton-polariton system is developed. A general relation for the homogeneous polariton linewidth is theoretically derived and experimentally used in the method. In experiments with a GaAs microcavity under nonresonant pulsed excitation, the reservoir temperature dynamics is extracted from the polariton linewidth. Within the first nanosecond the reservoir temperature greatly exceeds the lattice temperature and determines the dynamics of the major processes in the system. It is shown that, for nonresonant pulsed excitation of GaAs microcavities, the polariton Bose-Einstein condensation is typically governed by polariton-phonon scattering, while interparticle scattering leads to condensate depopulation.

description: This paper explores the impact of the Yang-Mills charge parameter and the exponent term on a $4$D black hole solution in the Einstein Power-Yang-Mills theory. Through an investigation of the massless scalar quasinormal mode spectrum, black hole shadow, and emission rate, we have determined that the effects of these two parameters are opposite. Specifically, the Yang-Mills charge parameter causes an increase in the real quasinormal frequencies with a correspondingly smaller damping rate. It also results in a smaller black hole shadow and a lower evaporation rate.

description: We provide a taxonomic and compositional characterization of Multiple Asteroid Systems (MASs) located in the main belt (MB) using visible and near-infrared (0.45-2.5 um) spectral data of 42 MB MASs. The mineralogical analysis is applied to determine meteorite analogs for the MASs, which, in turn, are applied to the MAS density measurements of Marchis et al. (2012) to estimate the system porosity. The macroporosities are used to evaluate the primary MAS formation hypotheses. The visible observing campaign includes 25 MASs obtained using the SOAR telescope with the Goodman High Throughput Spectrometer. The infrared observing campaign includes 34 MASs obtained using the NASA IRTF with the SpeX spectragraph. The MASs are classified using the Bus-DeMeo taxonomic system. We perform a NIR spectral band parameter analysis using a new analysis routine, the Spectral Analysis Routine for Asteroids (SARA). The SARA routine determines band centers, areas, and depths by utilizing the diagnostic absorption features near 1- and 2-um. The band parameter analysis provides the Gaffey subtype for the S-type MASs; the relative abundance olivine-to-pyroxene ratio; and olivine and pyroxene modal abundances for S-complex and V-type MASs. This mineralogical information is applied to determine meteorite analogs. We determine the H, L, and LL meteorite analogs for 15 MASs with ordinary chondrite-like (OC) mineralogies. We observe an excess (10/15) of LL-like mineralogies. Of the MASs with LL-like mineralogies, seven are consistent with Flora family membership, supporting the hypothesis that the Flora family is a source of LL-like NEAs and LL chondrites on Earth. Using the measured densities of the meteorite analog and the MAS densities from Marchis et al. (2012), we estimate the macroporosity for 13 MASs and find that all estimated macroporosities are in agreement with formation hypotheses.

description: The end-to-end lookup latency of a hierarchical index -- such as a B-tree or a learned index -- is determined by its structure such as the number of layers, the kinds of branching functions appearing in each layer, the amount of data we must fetch from layers, etc. Our primary observation is that by optimizing those structural parameters (or designs) specifically to a target system's I/O characteristics (e.g., latency, bandwidth), we can offer a faster lookup compared to the ones that are not optimized. Can we develop a systematic method for finding those optimal design parameters? Ideally, the method must have the potential to generate almost any existing index or a novel combination of them for the fastest possible lookup. In this work, we present new data and an I/O-aware index builder (called AirIndex) that can find high-speed hierarchical index designs in a principled way. Specifically, AirIndex minimizes an objective function expressing the end-to-end latency in terms of various designs -- the number of layers, types of layers, and more -- for given data and a storage profile, using a graph-based optimization method purpose-built to address the computational challenges rising from the inter-dependencies among index layers and the exponentially many candidate parameters in a large search space. Our empirical studies confirm that AirIndex can find optimal index designs, build optimal indexes within the times comparable to existing methods, and deliver up to 4.1x faster lookup than a lightweight B-tree library (LMDB), 3.3x--46.3x faster than state-of-the-art learned indexes (RMI/CDFShop, PGM-Index, ALEX/APEX, PLEX), and 2.0 faster than Data Calculator's suggestion on various dataset and storage settings.

description: A city (or an urban cluster) is not an isolated spatial unit, but a combination of areas with closely linked socio-economic activities. However, so far, we lack a consistent and quantitative approach to define multi-level urban clusters through these socio-economic connections. Here, using granular population distribution and flow data from China, we propose a bottom-up aggregation approach to quantify urban clusters at multiple spatial scales. We reveal six 'phases' (i.e., levels) in the population density-flow diagram, each of which corresponds to a spatial configuration of urban clusters from large to small. Besides, our results show that Zipf's law appears only after the fifth level, confirming the spatially dependent nature of urban laws. Our approach does not need pre-defined administrative boundaries and can be applied effectively on a global scale.

description: Harmonic oscillator model-space truncations introduce systematic errors to the calculation of binding energies and other observables. We identify the relevant infrared scaling variable and give values for this nucleus-dependent quantity. We consider isotopes of oxygen computed with the coupled-cluster method from chiral nucleon-nucleon interactions at next-to-next-to-leading order and show that the infrared component of the error is sufficiently understood to permit controlled extrapolations. By employing oscillator spaces with relatively large frequencies, well above the energy minimum, the ultraviolet corrections can be suppressed while infrared extrapolations over tens of MeVs are accurate for ground-state energies. However, robust uncertainty quantification for extrapolated quantities that fully accounts for systematic errors is not yet developed.

description: In the aftermath of the covid-19 pandemic, the prevention of further decline in aggregate employment and turning it around are high on the agenda of policymakers. To this end, it is imperative to have a disaggregated model of employment, given the unequal effects of covid-19 on employment in different sectors of the economy. In this paper we develop a multivariate time series model of employment in 19 sectors of the Australian economy. We provide the predictions of this model conditional on various scenarios that are based on the most recent quantitative information about sectoral employment in Australia. We estimate that the drop in total employment in the second quarter of 2020 will be in between 7 and 13 percentage points, compared to the second quarter of 2019. We also use this model to determine the long-run effect of a 1% increase in economic activity in any chosen sector on aggregate employment. Our findings point to manufacturing and construction sectors as those that might generate the largest positive spillovers for the rest of the economy. Moreover, we provide an interactive web-based app as well as an interactive spreadsheet that produce our model's 5-year forecasts based on any user-specified scenario for the current and following three quarters. As the covid-19 pandemic evolves and some restrictions are safely lifted or other restrictions become necessary, the sectoral employment multipliers together with the interactive tools produced here will provide useful information for policymakers.

description: Fundamental to quantitative characterization of the B cell receptor repertoire is clonal diversity - the number of distinct somatically recombined receptors present in the repertoire and their relative abundances, defining the search space available for immune response. This study synthesizes flow cytometry and immunosequencing to study memory and naive B cells from the peripheral blood of three adults. A combinatorial experimental design was employed, constituting a sample abundance probe robust to amplification stochasticity, a crucial quantitative advance over previous sequencing studies of diversity. These data are leveraged to interrogate repertoire diversity, motivating an extension of a canonical diversity model in ecology and corpus linguistics. Maximum likelihood diversity estimates are provided for memory and naive B cell repertoires. Both evince domination by rare clones and regimes of power law scaling in abundance. Memory clones have more disparate repertoire abundances than naive clones, and most naive clones undergo no proliferation prior to antigen recognition.

description: High-precision timing of millisecond pulsars (MSPs) over years to decades is a promising technique for direct detection of gravitational waves at nanohertz frequencies. Time-variable, multi-path scattering in the interstellar medium is a significant source of noise for this detector, particularly as timing precision approaches 10 ns or better for MSPs in the pulsar timing array. For many MSPs the scattering delay above 1 GHz is at the limit of detectability; therefore, we study it at lower frequencies. Using the LOFAR (LOw-Frequency ARray) radio telescope we have analyzed short (5-20 min) observations of three MSPs in order to estimate the scattering delay at 110-190 MHz, where the number of scintles is large and, hence, the statistical uncertainty in the scattering delay is small. We used cyclic spectroscopy, still relatively novel in radio astronomy, on baseband-sampled data to achieve unprecedented frequency resolution while retaining adequate pulse phase resolution. We detected scintillation structure in the spectra of the MSPs PSR B1257+12, PSR J1810+1744, and PSR J2317+1439 with diffractive bandwidths of $6\pm 3$, $2.0\pm 0.3$, and $\sim 7$ kHz, respectively, where the estimate for PSR J2317+1439 is reliable to about a factor of 2. For the brightest of the three pulsars, PSR J1810+1744, we found that the diffractive bandwidth has a power-law behavior $Δν_d \propto ν^α$, where $ν$ is the observing frequency and $α= 4.5\pm 0.5$, consistent with a Kolmogorov inhomogeneity spectrum. We conclude that this technique holds promise for monitoring the scattering delay of MSPs with LOFAR and other high-sensitivity, low-frequency arrays like SKA-Low.

description: The stationary properties of the Bose-Hubbard model under squeezed dissipation are investigated. The dissipative model does not possess a $U(1)$ symmetry, but parity is conserved: $\langle a_j \rangle \to -\langle a_j \rangle$. We find that $\langle a_j \rangle = 0$ always holds, so no symmetry breaking occurs. Without the onsite repulsion, the linear case is known to be critical. At the critical point the system freezes to an EPR state with infinite two mode entanglement. We show here that the correlations are rapidly destroyed whenever the repulsion is switched on. Then, the system approaches a thermal state with an effective temperature defined in terms of the squeezing parameter in the dissipators. We characterize this transition by means of a Gutzwiller {\it ansatz} and the Gaussian Hartree-Fock-Bogoliubov approximation.

description: Human sensing is significantly improving our lifestyle in many fields such as elderly healthcare and public safety. Research has demonstrated that human activity can alter the passive radio frequency (PRF) spectrum, which represents the passive reception of RF signals in the surrounding environment without actively transmitting a target signal. This paper proposes a novel passive human sensing method that utilizes PRF spectrum alteration as a biometrics modality for human authentication, localization, and activity recognition. The proposed method uses software-defined radio (SDR) technology to acquire the PRF in the frequency band sensitive to human signature. Additionally, the PRF spectrum signatures are classified and regressed by five machine learning (ML) algorithms based on different human sensing tasks. The proposed Sensing Humans among Passive Radio Frequency (SHAPR) method was tested in several environments and scenarios, including a laboratory, a living room, a classroom, and a vehicle, to verify its extensiveness. The experimental results show that the SHAPR method achieved more than 95% accuracy in the four scenarios for the three human sensing tasks, with a localization error of less than 0.8 m. These results indicate that the SHAPR technique can be considered a new human signature modality with high accuracy, robustness, and general applicability.

description: Increasing attention is currently given to carbyne, the sp1 hybridized one-dimensional carbon allotrope, because of its predicted outstanding mechanical, optical, and electrical properties. Although recently substantial progress has been reported on confined carbyne synthesized inside double-walled carbon nanotubes (DWCNTs), its formation mechanism and precursors for growth remain elusive. Here, we show a rational design of isotope engineered ultra-clean DWCNTs as tailored hosts to trace the growth of carbyne, which allows to identify the precursor and unravel the formation mechanism of carbyne during high-vacuum annealing at high-temperatures. Using this approach, ultra-clean DWCNTs with 80.4% 13C-enriched inner walls and outer tubes of naturally abundant served to unambiguously prove that only the carbonaceous materials inside the DWCNTs can act as precursors. The exchange of C atoms between inner and outer tubes happens without any growth of carbyne. After applying a secondary oxidation step, it is possible to produce the carbonaceous precursors from the partially oxidized DWCNTs. In this manner, not only carbyne with a record of ~28.8% 13C enrichment is grown, but concomitant healing, reorganization and regrowth of the DWCNTs occurs. This work enables to identify the precursor and trace the growth mechanism of confined carbyne with engineered properties. This is a crucial step, towards accessing the full application potential of confined carbyne hybrids by tailoring not only the isotopic fillers, but also the inner and outer tubes of the DWCNT hosts.

description: The motion of S2, one of the stars closest to the Galactic Centre, has been measured accurately and used to study the compact object at the centre of the Milky Way. It is commonly accepted that this object is a supermassive black hole but the nature of its environment is open to discussion. Here, we investigate the possibility that dark matter in the form of an ultralight scalar field ``cloud'' clusters around Sgr~A*. We use the available data for S2 to perform a Markov Chain Monte Carlo analysis and find the best-fit estimates for a scalar cloud structure. Our results show no substantial evidence for such structures. When the cloud size is of the order of the size of the orbit of S2, we are able to constrain its mass to be smaller than $0.1\%$ of the central mass, setting a strong bound on the presence of new fields in the galactic centre.

description: Obstructive sleep apnea (OSA) is a sleep-related breathing disorder commonly undiagnosed during preoperative evaluation in surgical patients. Kaiser Permanente (KP) has identified the preoperative screening of surgical patients for OSA as an area for improvement. Patients with OSA are at increased risk for cardiovascular, pulmonary, and endocrine disease. In addition, failure to diagnose patients with OSA is associated with increased perioperative complications. The literature review supports using the STOP-Bang questionnaire for the preoperative screening of patients for OSA. The purpose of this pilot project is to develop an educational module that highlights the diagnostic accuracy of the STOP-Bang questionnaire, clinical implications of OSA and will outline the best practices in the anesthetic management of patients with OSA. Anesthesia providers were invited to complete the educational module. A pre-module and post-module chart audit was conducted to monitor the rate of STOP-Bang questionnaire completion and adherence to clinical practice guidelines. While there were minimal differences in midazolam and narcotic administration, there was an increase in the number of STOP-Bang questionnaires completed post-intervention. A larger sample size is needed to evaluate the effect of this educational module on the perioperative management of OSA patients.
RAPPRESENTAZIONI LINGUISTICHE DEL TRIVENETO: MARGINALIT�, STEREOTIPI E ALTRI RIMEDI DEL CINEMA CONTEMPORANEO

description: Il decentramento produttivo che ha allontanato molta della cinematografia italiana da Roma ha rideterminato gli spazi del filmico, delle sue narrazioni e della lingua con cui allo spettatore vengono consegnate. La nascita di numerose film commission regionali e i finanziamenti stanziati da alcune regioni italiane per uno sviluppo culturale che passi anche attraverso il cinema hanno riaperto gli universi del grande schermo alla localit� e micro-realt� provinciali, ricordando un mondo quasi alle origini della parola filmata. Quest?ultima, per la sua specifica natura diamesica e nella continua ricerca della mediet� linguistica, riscopre oggi usi dialettali che non si riconoscono soltanto nel contorno di una stereotipia comica o ambientalistica, e che invece accolgono significati simbolici spesso difficili, a tratti critici e non sempre assimilabili agli italiani regionali di pi� larga diffusione nel territorio filmato. Il presente lavoro si � posto dunque l?obiettivo di interrogare, limitatamente all?area del Triveneto, la produzione filmica nel periodo compreso tra il 2010 e il 2015 per cercare di capire cosa abbia accolto, delle proprie identit� linguistiche, una regione cos� poco rappresentata e rappresentativa di s� stessa all?interno del cinema italiano. Lo sguardo del cinema a Nord-Est si � caratterizzato, infatti, negli anni passati, per una forte stereotipia e dicotomia nelle rappresentazioni filmiche e nella lingua in esse filmata: Venezia � stata la citt� pi� vista dal cinema (forse la pi� amata) eppure, allo stesso tempo, anche la pi� negata. La rappresentazione regionale limitata a una singola citt� ha inoltre avuto non poche conseguenze sulla lingua che il cinema ha trasmesso: la koin� veneziana � stata la sola lingua che il cinema abbia accolto e si � cos� affermata, nella comune opinione, quale dialetto egemone di un territorio che, contrariamente, conosce molteplici variet� dialettali. Infine, al dialetto o, sarebbe meglio dire, all?italiano regionale del Veneto il cinema ha assegnato spesso ruoli di contorno, tratti tipizzati di quella che � divenuta una maschera: i veneti potevano essere soltanto servi, cameriere, carabinieri o soldati, ancora meglio se ingenui. Attraverso l?analisi linguistica di otto pellicole , la ricerca si � pertanto concentrata a trovare le risposte a una pluralit� di domande: a quali espedienti ricorre oggi la lingua filmata per ottenere il maggior grado di verosimiglianza con l?oralit�; qual � l?italiano che trasmette e quale il dialetto; se quest?ultimo sia ancora legato alla koin� veneziana della tradizione o se invece si possa parlare di dialetti del Triveneto presenti nel cinema; quali i ruoli o i valori simbolici che i diversi codici assumono all?interno di quella tavolozza a tratti distorcente, a tratti mimetica che � la realt� dello schermo.

description: We show that less than 10% of the barrier area dominates the electron tunneling in state-of-art Al/AlOx/Al Josephson junctions. They have been studied by transmission electron microscopy, specifically using atomic resolution annular dark field (ADF) scanning transmission electron microscopy (STEM) imaging. The direct observation of the local barrier thickness shows a Gaussian distribution of the barrier thickness variation along the junction, from ~1 nm to ~2 nm in the three junctions we studied. We have investigated how the thickness distribution varies with oxygen pressure (po) and oxidation time (to) and we find, in agreement with resistance measurements on similar junctions, that an increased to gives a thicker barrier than an increased po.

description: We investigate the altermagnetic properties of strongly-correlated transition metal oxides considering the family of the quasi two-dimensional A2BO4 and three-dimensional ABO3. As a test study, we analyze the Mott insulators Ca2RuO4 and YVO3. In both cases, the orbital physics is extremely relevant in the t2g subsector with the presence of an orbital-selective Mott physics in the first case and of a robust orbital-order in the second case. Using first-principles calculations, we show the presence of an orbital-selective altermagnetism in the case of Ca2RuO4. In the case of YVO3, we study the altermagnetism as a function of the magnetic ordering and of the Coulomb repulsion U. We find that the altermagnetism is present in all magnetic orders with the symmetries of the Brillouin zone depending on the magnetic order. Finally, the Coulomb repulsion enhances the non-relativistic spin-splitting making the strongly-correlated systems an exciting playground for the study of the altermagnetism.

description: This chapter surveys work dedicated to macroeconomic analysis using an agent- based modeling approach. After a short review of the origins and general characteristics of this approach a systemic comparison of the structure and modeling assumptions of a set of important (families of) agent-based macroeconomic models is provided. The comparison highlights substantial similarities between the different models, thereby identifying what could be considered an emerging common core of macroeconomic agent-based modeling. In the second part of the chapter agent-based macroeconomic research in different domains of economic policy is reviewed.

description: We investigate the effects of inhomogeneities on spin entanglement in many-electron systems from an ab-initio approach. The key quantity in our approach is the local spin entanglement length, which is derived from the local concurrence of the electronic system. Although the concurrence for an interacting systems is a highly nonlocal functional of the density, it does have a simple, albeit approximate expression in terms of Kohn-Sham orbitals. We show that the electron localization function -- well known in quantum chemistry as a descriptor of atomic shells and molecular bonds -- can be reinterpreted in terms of the ratio of the local entanglement length of the inhomogeneous system to the entanglement length of a homogenous system at the same density. We find that the spin entanglement is remarkably enhanced in atomic shells and molecular bonds.
