description: We develop estimators of agreement and disagreement between correlated cosmological data sets. These account for data correlations when computing the significance of both tensions and excess confirmation while remaining statistically optimal. We discuss and thoroughly characterize different approaches commenting on the ones that have the best behavior in practical applications. We complement the calculation of their statistical distribution within the Gaussian model with one estimator that takes non-Gaussianities fully into account. To illustrate the use of our techniques, we apply these estimators to supernovae measurements of the distance-redshift relation, absolutely calibrated by the local distance ladder. The suite of best estimators that we discuss finds results that are in excellent agreement between estimators and find no indications of significant internal inconsistencies in this data set above the $1\%$ probability threshold. This shows the robustness of local determinations of the Hubble constant to features in the distance-redshift relation.

description: To estimate comprehensive cost of rheumatoid arthritis (RA) patients to society and individual stakeholders, including patients/employees, employers, family members/caregivers, and government. Administrative claims databases covering privately insured and Medicare and Medicaid beneficiaries in the US were used to compute the excess payer and beneficiary-paid costs per patient with RA compared with matched controls. Similarly, per-person excess costs for caregivers and uninsured patients with RA were estimated. Costs were estimated for other burdens, including costs of work-loss to employers, adaptations to home and work environments, lost on-the-job productivity, informal and hired care/household help, and job turnover costs. Intangible costs associated with quality-of-life deterioration were estimated based on legal system jury awards, whereas costs for premature mortality were based on lifetime earnings data. Per-capita cost estimates were weighted by the relevant population to estimate societal costs. Because data were incomplete, several assumptions were required; these assumptions could lead to an over- or under-estimation of cost burdens. Annual excess health care costs of RA patients were $8.4 billion, and costs of other RA consequences were $10.9 billion. These costs translate to a total annual cost of $19.3 billion. From a stakeholder perspective, 33% of the total cost was allocated to employers, 28% to patients, 20% to the government, and 19% to caregivers. Adding intangible costs of quality-of-life deterioration ($10.3 billion) and premature mortality ($9.6 billion), total annual societal costs of RA (direct, indirect, and intangible) increased to $39.2 billion. Societal costs of RA in the US are $19.3 billion and $39.2 billion (in 2005 dollars) without and with intangible costs, respectively. This study was one of the first to attempt to quantify the comprehensive burdens of RA. Despite several assumptions made in areas in which few data exist, the findings generate useful insights into the full burden of RA.

description: The dynamic feedback problem in regional agricultural production response or planning models can be divided into two parts. One part is intertemporal dynamic feedback which involves the time-dating relationship between production response and price as a lagged phenomenon. The other part of the problem involves changing the aggregation of subgroups over time. This paper suggests including a first order Markov transition probability within the model to handle the problem of aggregate changes over time. Because the model is intertemporal, it also accounts for the interrelationship among time horizons in the addition to the interrelationship among subgroups in the model. Including progressive income tax, which affects production and consumption, normally would require integer programming to handle the nonconvexity. However, this is handled here by stepwise approximation and is uniquely connected to the dynamic system of aggregation in the model.

description: This article describes nonequilibrium techniques for the calculation of free energies of solids using molecular dynamics (MD) simulations. These methods provide an alternative to standard equilibrium thermodynamic integration methods and often present superior efficiency. Here we describe the implementation in the LAMMPS (Large-scale Atomic/Molecular Massively Parallel Simulator) code of two specific nonequilibrium processes that allow the calculation of the free-energy difference between two different system Hamiltonians as well as the free-energy temperature dependence of a given Hamiltonian, respectively. The theory behind the methods is summarized, and we describe (including fragments of LAMMPS scripts) how the process parameters should be selected to obtain the best-possible efficiency in the calculations of free energies using nonequilibrium MD simulations. As an example of the application of the methods we present results related to polymorphic transitions for a classical potential model of iron.

description: A low mass-to-light ratio for the stellar component of spiral galaxies (M/L<1 in the I-band) is advocated by various dynamical arguments and by recent cosmological simulations of the formation of these systems. We discuss this possibility by means of chemo-photometric models for galactic discs, adopting different Initial Mass Functions. We show that a number of "bottom--light" IMFs (namely, with less mass locked in low-mass stars than the standard Salpeter IMF), suggested independently in recent literature, do imply M/L ratios as low as mentioned above, at least for late type spirals (Sbc/Sc). This conclusion still holds when the bulge contribution to mass and light is included. We also predict the typical stellar M/L ratio, and correspondingly the zero-point of the Tully-Fisher relation, to vary considerably with Hubble type (about 0.5-0.7 mag in the red bands, from Sa to Sc type). For some of the bottom-light IMFs considered, the efficiency of metal production tends to exceed what is typically estimated for spiral galaxies. Suitable tuning of the IMF mass limits, post-supernova fallback of metals onto black holes or metal outflows must then be invoked, to reproduce the observed chemical properties of disc galaxies. In the appendix we provide M/L-colour relations to estimate the stellar M/L ratio of a galaxy on the base of its colours, for several IMFs.

description: Over the last few years, there has been a rising trend towards the field of distributed testing where the implementation under test (IUT) has physical distributed ports. However, running several testers in such ports can lead to a number of coordination and synchronisation issues between these remote testers. We suggest in previous works to cope with these problems by enhancing the test architecture with some timing constraints. In this paper, we introduce a new algorithm to generate local timed test sequences so as to describe the behaviour of the test at each port. We aim through this algorithm to reduce the number of messages exchanged among the testers. Moreover, we illustrate our approach through a case study using MapReduce architecture with several worker components. These systems commonly encounter failures as a result of several circumstances, such as hardware faults, power outages, or network connection delays. To this end, we set the temporal properties in the specification of these systems. Then, we apply our algorithm to derive the related timed local test sequences. Furthermore, we explain how to apply our approach in the case of MapReduce testing to identify faulty workers, in order to reschedule their tasks to a healthy worker.
Abundance of beryllium in the Sun and stars: The role of non-local thermodynamic equilibrium effects

description: Earlier studies have suggested that deviations from the local thermodynamic equilibrium (LTE) play a minor role in the formation of Be II 313 nm resonance lines in solar and stellar atmospheres. Recent improvements in the atomic data allow a more complete model atom of Be to be constructed and the validity of these claims to be reassessed using more up-to-date atomic physics. The main goal of this study therefore is to refocus on the role of non-local thermodynamic equilibrium (NLTE) effects in the formation of Be II 313.04 and 313.11 nm resonance lines in solar and stellar atmospheres. For this, we constructed a model atom of Be using new atomic data that recently became available. The model atom contains 98 levels and 383 radiative transitions of Be I and Be II and uses the most up-to-date collision rates with electrons and hydrogen. This makes it the most complete model atom used to determine 1D NLTE solar Be abundance and to study the role of NLTE effects in the formation of Be II 313 nm resonance lines. We find that deviations from LTE have a significant influence on the strength of the Be II 313 nm line in solar and stellar atmospheres. For the Sun, we obtained the 1D NLTE Be abundance of A(Be)_NLTE = 1.32+/-0.05, which is in excellent agreement with the meteoritic value of A(Be)=1.31+/-0.04. Importantly, we find that NLTE effects become significant in FGK stars. Moreover, there is a pronounced variation in 1D NLTE-LTE abundance corrections with the effective temperature and metallicity. Therefore, contrary to our previous understanding, the obtained results indicate that NLTE effects play an important role in Be line formation in stellar atmospheres and have to be properly taken into account in Be abundance studies, especially in metal-poor stars.

description: Raman light-scattering experiments in the antiferromagnetic phase of the Cu_2Te_2O_5(Br_(1-x)Cl_x)_2 compounds are analyzed in terms of a dimerized spin model for the tetrahedral Cu-clusters. It is shown that the longitudinal magnetic excitation in the pure Br system hybridizes with a localized singlet excitation due to the presence of a Dzyaloshinskii-Moriya anisotropy term. The drastic change of the magnetic scattering intensities observed when a proportion of Br is replaced by Cl ions, is proposed to be caused by a change of the magnetic order parameter. Instead of being parallel/antiparallel with each other, the spins in the two pairs of spin-1/2 order perpendicular to each other, when the composition x is larger than about 0.25.

description: Short Range Correlations (SRCs) have been identified as being responsible for the high momentum tail of the nucleon momentum distribution, n(k). Hard, short-range interactions of nucleon pairs generate the high momentum tail and imprint a universal character on n(k) for all nuclei at large momentum. Triple coincidence experiments have shown a strong dominance of np pairs, but these measurements involve large final state interactions. This paper presents the results from Jefferson Lab experiment E08014 which measured inclusive electron scattering cross-section from Ca isotopes. By comparing the inclusive cross section from 48Ca to 40Ca in a kinematic region dominated by SRCs we provide a new way to study the isospin structure of SRCs.

description: The group of lambda Bootis type stars comprises late B- to early F-type, Population I objects which are basically metal weak, in particular the Fe group elements, but with the clear exception of C, N, O and S. One of the theories to explain the abundance pattern of these stars involves circumstellar or interstellar matter around the objects. Hence, we have compiled all available data from the literature of well established members of the lambda Bootis group redward of 7000A in order to find evidence for matter around these objects. Furthermore, we present unpublished ISO as well as submillimeter continuum and CO (2-1) line measurements to complete the data set. In total, measurements for 34 (26 with data redward of 20 mu m) well established lambda Bootis stars are available. There is evidence for an infrared excesses in six stars (HD 31295, HD 74873, HD 110411, HD 125162, HD 198160/1 and HD 210111) and two are doubtful cases (HD 11413 and HD 192640) resulting in a percentage of 23% (excluding the two doubtful cases). Dust models for these objects show fractional dust luminosities comparable to the Vega-type stars and slightly higher dust temperatures. ISO-SWS spectroscopy for HD 125162 and HD 192640 resulted in the detection of pure stellar HI lines ruling out an active accretion disk (as found for several Herbig Ae/Be stars) around these objects. The submillimeter measurements gave only upper limits for the line and continuum fluxes.

description: We report on high-resolution interferometer observations of the 12CO(J=1-0) emission in the central 5 kpc region of the Seyfert 2 galaxy NGC 4501. The observations were made using the Nobeyama Millimeter Array during a long-term CO line survey of Virgo spirals. The major features are: (1) a nuclear concentration with a radius of r~5'' (390 pc), which is resolved into double peaks, and (2) spiral arms which extend out from the nuclear region. The nuclear component has a mass of 1.3x10^8 Mo, which corresponds to ~3.5% of the dynamical mass, and shows a slight non-circular motion. The double peaks are separated by ~4''.7. (370 pc), and located on the root of optical spiral arms in a HST image. The gas arms are associated with the spiral dust lanes, and are linked to the central double peaks. The non-circular motions along the molecular arms indicate the fact that the gas is driven by the density wave, rather than the stochastic processes. We calculated the gas cloud orbits in a stellar spiral potential, and explained the observed CO spiral arms and non-circular motions. We suggest that the central gas condensation arises from spiral-driven gas transfer. We estimated and compared the effect of two possible mechanisms of angular-momentum transfer: galactic shock, and gravitational torques. We discuss that the galactic shock is dominant.

description: Modern music retrieval systems often rely on fixed representations of user preferences, limiting their ability to capture users' diverse and uncertain retrieval needs. To address this limitation, we introduce Diff4Steer, a novel generative retrieval framework that employs lightweight diffusion models to synthesize diverse seed embeddings from user queries that represent potential directions for music exploration. Unlike deterministic methods that map user query to a single point in embedding space, Diff4Steer provides a statistical prior on the target modality (audio) for retrieval, effectively capturing the uncertainty and multi-faceted nature of user preferences. Furthermore, Diff4Steer can be steered by image or text inputs, enabling more flexible and controllable music discovery combined with nearest neighbor search. Our framework outperforms deterministic regression methods and LLM-based generative retrieval baseline in terms of retrieval and ranking metrics, demonstrating its effectiveness in capturing user preferences, leading to more diverse and relevant recommendations. Listening examples are available at tinyurl.com/diff4steer.

description: We produce the first set of radiation hydrodynamics simulations of binary AGNs at parsec-scale separation in scale-model simulations. We use SPH for hydrodynamics, and raytracing to calculate optical depths and radiation pressure from the two AGNs. We confirm that, without radiation pressure, the sign of gravitational torque is sensitive to the binary parameters, although in one of our two orbital configurations the binary should coalesce in a time-scale of $<10^9$ yr. However, radiation pressure quickly destroys the 'minitori' around each SMBH, drastically reducing gravitational torques and accretion, and greatly increasing the coalescence time-scale. Our simulations suggest a new 'minitorus' duty cycle with a time-scale of ~10 binary periods (~$10^6$ yr when scaling our models to a total binary mass of $2\times10^7\,M_\odot$). The growth and blow-out phases of the 'minitori' are of similar time-scales, and thus we expect about half of observed binary SMBHs to be active, in at least one component. The 'minitorus' structure provides asymmetries that could be observed by infrared interferometry.

description: Forecast the return on investment (ROI) for advances in biologic therapies in years 2015 and 2030, based upon impact on disease prevalence, morbidity, and mortality for asthma, diabetes, and colorectal cancer. A deterministic, spreadsheet-based, forecasting model was developed based on trends in demographics and disease epidemiology. ‘Return’ was defined as reductions in disease burden (prevalence, morbidity, mortality) translated into monetary terms; ‘investment’ was defined as the incremental costs of biologic therapy advances. Data on disease prevalence, morbidity, mortality, and associated costs were obtained from government survey statistics or published literature. Expected impact of advances in biologic therapies was based on expert opinion. Gains in quality-adjusted life years (QALYs) were valued at $100,000 per QALY. The base case analysis, in which reductions in disease prevalence and mortality predicted by the expert panel are not considered, shows the resulting ROIs remain positive for asthma and diabetes but fall below $1 for colorectal cancer. Analysis involving expert panel predictions indicated positive ROI results for all three diseases at both time points, ranging from $207 for each incremental dollar spent on biologic therapies to treat asthma in 2030, to $4 for each incremental dollar spent on biologic therapies to treat colorectal cancer in 2015. If QALYs are not considered, the resulting ROIs remain positive for all three diseases at both time points. Society may expect substantial returns from investments in innovative biologic therapies. These benefits are most likely to be realized in an environment of appropriate use of new molecules. The potential variance between forecasted (from expert opinion) and actual future health outcomes could be significant. Similarly, the forecasted growth in use of biologic therapies relied upon unvalidated market forecasts.

description: Ecosystems around the world are changing due to interacting local and global stressors. These changes are likely to affect ecosystem services - the benefits that ecosystems contribute to human wellbeing - but the complexity of social-ecological processes underpinning these services limits our understanding change. In this thesis, I examine changes in ecosystem services associated with climate-impacted tropical coral reefs and implications for the wellbeing of coastal communities. I draw on empirical data from the Seychelles, where two mass bleaching events (1998, 2016) have affected benthic and fish community composition. I first provide an overview of coral reef ecosystem services research and use empirical interview data from tourism and fishery key informants to understand the social-ecological aspects of services at the level of the service provider. This reveals the complexity of service providers underpinning locally valued services and benefits, but also the advantages of dis-aggregating service providers and their traits to understand how services are likely to respond to environmental change. Shifting from conceptualisations of change to lived experiences of change, I then explore how changes in ecosystem services are perceived by coral reef fishers. Changes have been perceived, though perceptions differ according to fishers’ characteristics, and have implications for the material, relational and subjective dimensions of fishers’ wellbeing. Finally, I draw on a social wellbeing approach to examine how the marine environment, and changes therein, affect fishers’ understanding of and ability to live well. This reveals tensions in fishers’ ability to pursue wellbeing, shaped by the social-ecological context in which changes to nearshore environments occur. These findings have implications for how changes in ecosystem services are investigated and highlight the need for multiple disciplinary perspectives to better understand the consequences of environmental change for human wellbeing.

description: The identification and modeling of the terrain from point cloud data is an important component of Terrestrial Remote Sensing (TRS) applications. The main focus in terrain modeling is capturing details of complex geological features of landforms. Traditional terrain modeling approaches rely on the user to exert control over terrain features. However, relying on the user input to manually develop the digital terrain becomes intractable when considering the amount of data generated by new remote sensing systems capable of producing massive aerial and ground-based point clouds from scanned environments. This article provides a novel terrain modeling technique capable of automatically generating accurate and physically realistic Digital Terrain Models (DTM) from a variety of point cloud data. The proposed method runs efficiently on large-scale point cloud data with real-time performance over large segments of terrestrial landforms. Moreover, generated digital models are designed to effectively render within a Virtual Reality (VR) environment in real time. The paper concludes with an in-depth discussion of possible research directions and outstanding technical and scientific challenges to improve the proposed approach.

description: Arrup doii (Takakuwa, 1940)
This species was described from ‘Keizyo’ [= Seoul], Korea, and then recorded from Honshu by Chamberlin & Wang (1952) and Shinohara (1957) and from Taiwan by Wang (1959).
 The original description provided by Takakuwa (1940) is inadequate, as the diagnosis of this species was mainly based on the "hairy" surface of the mandibles. However, small scale­like or digitiform cuticular processes (similar to dense hair) on the ventral side of mandibles is a common feature among several mecistocephalids and is probably widely distributed in other centipedes. Presently, it is not possible to assess whether A. doii is actually a distinct species, as no other clearly distinctive character emerges from the original description.
In any case, records from Japan and Taiwan are unwarranted, as they were based most probably on the presence of ‘hairy’ mandibles.

description: Data on Figshare is the Online Only Supplemental Data for Effects of High-Intensity Interval Training on Physical and Cognitive Function in Middle-Aged Male Mice.Abstract: Declining functional capacity, both physical and cognitive, is a consequence of aging. However, exercise is a promising intervention to mitigate normal age-related decline. While many studies have been done elucidating the benefits of exercise per se, less well-studied is the effect of high intensity interval training (HIIT) on a middle-aged population. Our primary purpose was to assess the effect of three months of HIIT on physical and cognitive performance in middle-aged (17-month-old) male C57BL/6J mice, compared to sedentary controls. We hypothesized that exercised mice would be resistant to any decline in cognitive and physical ability, both measured pre- and post-intervention. To measure physical function, we used the well-validated CFAB (comprehensive functional assessment battery) scoring system comprised of determinants including voluntary wheel running, inverted cling, grip test, treadmill max speed, and rotarod. We measured cognition with open field, novel object recognition, y-maze, and puzzle box. Further measures of sarcopenia/frailty included body composition (MRI) and in vivo contractile physiology (plantar flexor torque). Training resulted in significant aerobic capacity improvements for the HIIT group, increasing treadmill time by 28%, while the SED group demonstrated a 41.4% decline in treadmill time. However, no significant differences in cognitive function were determined. Contrary to our previous research in other age groups, the current study found little effect of HIIT on body composition. We note that at 17 months old, mice did not experience any evidence of cognitive deterioration in either group over the three-month period, thus explaining the lack of exercise effect. We found that HIIT had less influence on either physical or cognitive function than we expected—which may be because function in this age group is stable. Future work will investigate older adult cognitive response to HITT at ages where there is well-documented cognitive decline.

description: The behaviour of matrix string theory in the background of a type IIA pp wave at small string coupling, g_s << 1, is determined by the combination M g_s where M is a dimensionless parameter proportional to the strength of the Ramond-Ramond background. For M g_s << 1, the matrix string theory is conventional; only the degrees of freedom in the Cartan subalgebra contribute, and the theory reduces to copies of the perturbative string. For M g_s >> 1, the theory admits degenerate vacua representing fundamental strings blown up into fuzzy spheres with nonzero lightcone momenta. We determine the spectrum of small fluctuations around these vacua. Around such a vacuum all N-squared degrees of freedom are excited with comparable energies. The spectrum of masses has a spacing which is independent of the radius of the fuzzy sphere, in agreement with expected behaviour of continuum giant gravitons. Furthermore, for fuzzy spheres characterized by reducible representations of SU(2) and vanishing Wilson lines, the boundary conditions on the field are characterized by a set of continuous angles which shows that generically the blown up strings do not ``close''.

description: Quasi-periodic oscillations (QPOs) are often present in the X-ray flux from accreting stellar-mass black holes (BHs). If they are due to relativistic (Lense-Thirring) precession of an inner accretion flow which is misaligned with the disc, the iron emission line caused by irradiation of the disc by the inner flow will rock systematically between red and blue shifted during each QPO cycle. Here we conduct phase-resolved spectroscopy of a $\sim2.2$ Hz type-C QPO from the BH X-ray binary GRS 1915+105, observed simultaneously with NICER and NuSTAR. We apply a tomographic model in order to constrain the QPO phase-dependent illumination profile of the disc. We detect the predicted QPO phase-dependent shifts of the iron line centroid energy, with our best fit featuring an asymmetric illumination profile ($>2σ$ confidence). The observed line energy shifts can alternatively be explained by the spiral density waves of the accretion-ejection instability model. However we additionally measure a significant ($>3σ$) modulation in reflection fraction, strongly favouring a geometric QPO origin. We infer that the disc is misaligned with previously observed jet ejections, which is consistent with the model of a truncated disc with an inner precessing hot flow. However our inferred disc inner radius is small ($r_\text{in}{\sim} 1.4 GM/c^2$). For this disc inner radius, Lense-Thirring precession cannot reproduce the observed QPO frequency. In fact, this disc inner radius is incompatible with the predictions of all well-studied QPO models in the literature.

description: Liquid water is one of the key elements in the search for possible life outside of the Earth and has a wide range of consequences on various chemical and geological processes. The InSight probe landed on Mars with a special equipment dedicated to examine geophysical characteristics and internal heat flow of the planet and some meteorological instruments also included in the payload. We examine the annual and daily variations of near-surface relative humidity and surface temperature calculated from the General Circulation Model (GCM) at Elysium Planitia, the landing site of InSight and search for possible ideal times for deliquescence. We inspect three different hygroscopic salts, but find that out of the three only calcium-perchlorate could liquify at the environment of InSight. We find that nighttime ideal periods could occur in a limited window between approximately Ls 90 and 150 at the late evening hours centered around 9 PM. In our daily studies we find no instances where the whole night could be ideal for deliquescence. This is mostly due to the temperatures dropping below eutectic level leading to a 0.5 - 2 hour long presumed ideal period before midnight. On multiple occasions the temperature is just a few degrees below the necessary limit while relative humidity is high enough, therefore the precise temperature measurements of InSight could be critical in determining ideal periods for deliquescence.
On default priors for robust Bayesian estimation with divergences

description: This paper presents objective priors for robust Bayesian estimation against outliers based on divergences. The minimum $γ$-divergence estimator is well-known to work well estimation against heavy contamination. The robust Bayesian methods by using quasi-posterior distributions based on divergences have been also proposed in recent years. In objective Bayesian framework, the selection of default prior distributions under such quasi-posterior distributions is an important problem. In this study, we provide some properties of reference and moment matching priors under the quasi-posterior distribution based on the $γ$-divergence. In particular, we show that the proposed priors are approximately robust under the condition on the contamination distribution without assuming any conditions on the contamination ratio. Some simulation studies are also presented.

description: We have investigated the two open clusters NGC 6192 and NGC 6451 for which widely different reddening values and thus ages and distances can be found in the literature via Stroemgren uvby photometry. Our measurements allow to disentangle the apparent discrepancies from the literature and to derive new accurate values. From appropriate calibrations we find that the overall abundance for NGC 6192 is about solar whereas a subsolar value for NGC 6451 was estimated. From two previous reported photometrically candidate CP stars, one within NGC 6192 shows Stroemgren indices typical for a B8Si star whereas the other object of NGC 6451 is most probably a foreground G-type star.

description: We use time-resolved (TR) measurements based on the polar magneto-optical Kerr effect (MOKE) to study the magnetization dynamics excited by spin orbit torques in Py (Permalloy)/Pt and Ta/CoFeB bilayers. The analysis reveals that the field-like (FL) spin orbit torque (SOT) dominates the amplitude of the first oscillation cycle of the magnetization precession and the damping-like (DL) torque determines the final steady-state magnetization. In our bilayer samples, we have extracted the effective fields, hFL and hDL, of the two SOTs from the time-resolved magnetization oscillation spectrum. The extracted values are in good agreement with those extracted from time-integrated DCMOKE measurements, suggesting that the SOTs do not change at high frequencies. We also find that the amplitude ratio of the first oscillation to steady state is linearly proportional to the ratio hFL/hDL. The first oscillation amplitude is inversely proportional to, whereas the steady state value is independent of, the applied external field along the current direction.
