description: We have studied the magnetic properties of free cobalt clusters in two semi-independent Stern-Gerlach deflection experiments at temperatures between 60 and 307 K. We find that clusters consisting of 13 to 200 cobalt atoms exhibit behavior that is entirely consistent with superparamagnetism, though complicated by finite-system fluctuations in cluster temperature. By fitting the data to the Langevin function, we report magnetic moments per atom for each cobalt cluster size and compare the results of our two measurements and all those performed previously. In addition to a gradual decrease in moment per atom with increasing size, there are oscillations that appear to be caused by geometrical shell structure. We discuss our observations in light of the two competing models for Langevin-like magnetization behavior in free clusters, superparamagnetism and adiabatic magnetization, and conclude that the evidence strongly supports the superparamagnetic model.

Coronal mass ejections, which are explosions of solar material and energy into space, pose a potential threat to satellite and electrical grid infrastructures, yet little is known about the solar corona. Various questions exist, relating to the origins of these mass ejections as well as the mechanisms involved in coronal heating. The corona and coronal mass ejections are measured by satellite and ground-based coronagraphs, instruments that produce a false eclipse of the Sun in order to separate the extremely faint coronal signature from the bright solar disk. Earth’s atmosphere and the presence of aerosols limit the usefulness of images obtained from ground-based coronagraphs compared to satellite observations. We have developed image processing algorithms to remove aerosols from a new high-speed detector in real time. Two images, a mean and a median image, were first generated from a time series of images containing real aerosols. Then a thresholding algorithm was applied to all of the images within the time series. If the pixel values exceeded the mean and/or median image value, they were replaced with the value in that mean or median image. Both techniques were successful in removing aerosols from imagery. Due to signal-to-noise advantages gained by utilizing the mean image instead of the median image, the mean is the preferred method. Processing ∼1 second of imagery (150 frames per second) required ∼180 seconds on a dual-core 2.33 GHz CPU. Further optimization will promote real-time aerosol removal in solar observation.

description: We investigate the entanglement properties of a finite size 1+1 dimensional Ising spin chain, and show how these properties scale and can be utilized to reconstruct the ground state wave function. Even at the critical point, few terms in a Schmidt decomposition contribute to the exact ground state, and to physical properties such as the entropy. Nevertheless the entanglement here is prominent due to the lower-lying states in the Schmidt decomposition.

description: We develop an estimator for the high-dimensional covariance matrix of a locally stationary process with a smoothly varying trend and use this statistic to derive consistent predictors in nonstationary time series. In contrast to the currently available methods for this problem the predictor developed here does not rely on fitting an autoregressive model and does not require a vanishing trend. The finite sample properties of the new methodology are illustrated by means of a simulation study and a financial indices study. Supplementary materials for this article are available online.

Road weather

Each year, adverse weather along roadways results in over 7,000 fatalities, 673,000 injuries, nearly $9.5 billion in congestion delays, and costs shipping companies $3.5 billion. Currently, decision support systems recommend road surface treatments for snow removal operations by incorporating output from pavement temperature models. However, current pavement temperature models issue point forecasts that fail to describe the conditions between the points. A forecast from a gridded pavement model is a possible solution to this problem. To produce this forecast, the sensitivity of the pavement temperature when stratified by different materials (i.e., concrete and asphalt) and their thicknesses must be assessed. This analysis used eight Road Weather Information System (RWIS) stations in the greater Denver, Colorado metropolitan area and four RWIS sites at Denver International Airport. Uniform radiation was assumed using a cross-referencing method between five-minute daily weather observations and satellite-surface composite maps. Sixteen total case studies were selected for day and night with diverse weather conditions. Concrete roads generally averaged 3.2° C warmer than asphalt roads and therefore will have to be modeled separately. Elevated (e.g., overpass) and non-elevated surfaces were also compared, and elevated roads tended to be 3.3° C cooler than non-elevated; therefore, a condition protocol for the elevated site will subtract 3° C from the standard forecast. This work lays the foundation for additional analyses with a more robust data set to confirm initial results observed from these data, the results of which may be used to develop and tune gridded pavement model forecasts.

description: We study the relationship between shockwave geometries and the gravitational memory effect in four-dimensional asymptotically flat spacetime. In particular, we show the 't Hooft commutation relations of shockwave operators are equivalent to the commutation relation between soft and Goldstone modes parametrizing a sector of the gravitational phase space. We demonstrate this equivalence via a diffeomorphism that takes a shockwave metric to a metric whose transverse traceless component is the gravitational memory. The shockwave momentum in 't Hooft's analysis is related to the soft graviton mode, which is responsible for the memory effect, while the shift in the shockwave position is related to the Goldstone mode. This equivalence opens new directions to utilize the gravitational memory effect to explore the observational implications of shockwave geometries in flat space.

description: Using the extended J, H and K magnitudes provided by the 2MASS data archive, we consider the position of brightest cluster galaxies (BCGs) in the observed relations between inferred supermassive black hole (SMBH) mass and the host galaxy properties, as well as their position in the stellar velocity dispersion and luminosity (sigma-L) relation, compared to E and S0 galaxies. We find that SMBH masses (M) derived from near-infrared (NIR) magnitudes do not exceed 10e9.5Msol and that these masses agree well with the predictions made from sigma. In the NIR, there is no evidence that BCGs leave the sigma-L relation defined by less luminous galaxies. The higher SMBH masses predicted from V-band luminosities (M~10e10.5Msol) are attributed to the presence of extended envelopes around the BCGs, however, this will need to be confirmed using deeper multiwavelength imaging.

Extrinsic higher-order topological corner states in AB-stacked transition-metal dichalcogenides

description: Higher-order topological insulators (HOTIs) are a novel type of topological phases which supports $d$-dimensional topological boundary states in $D$-dimensional systems with $D-d>1$. In this work, we theoretically predict that interlayer couplings in AB-stacked bilayer transition-metal dichalcogenides (TMDs) lead to the emergence of extrinsic second-order topological phases, where corner states are induced by the band inversion of zigzag edge bands. We find that the systems feature a quantized multiband Berry phase defined for a zigzag nanoribbon geometry, unveiling the nontrivial topological properties of its two zigzag edges. With detailed investigation into the bilayer TMDs under different geometries, we find two types of boundary-obstructed corner states arising from different corner terminations of either the same type of or heterogeneous zigzag edges. The topological nature of these corner states and their degeneracy is further analyzed with both the crystalline symmetries of different geometries, and a topological phase transition of the Berry phase induced by a layer-dependent onsite energy.

description: In this paper we propose a regularization approach for network modeling of German power derivative market. To deal with the large portfolio, we combine high-dimensional variable selection techniques with dynamic network analysis. The estimated sparse interconnectedness of the full German power derivative market, clearly identify the significant channels of relevant potential risk spillovers. Our empirical findings show the importance of interdependence between different contract types, and identify the main risk contributors. We further observe strong pairwise interconnections between the neighboring contracts especially for the spot contracts trading in the peak hours, its implications for regulators and investors are also discussed. The network analysis of the full German power derivative market helps us to complement a full picture of system risk, and have a better understanding of the German power market functioning and environment.

description: We investigate the effect of uniaxial heterostrain on the interacting phase diagram of magic-angle twisted bilayer graphene. Using both self-consistent Hartree-Fock and density-matrix renormalization group calculations, we find that small strain values ($ε\sim 0.1 - 0.2 \%$) drive a zero-temperature phase transition between the symmetry-broken Kramers intervalley-coherent insulator and a nematic semi-metal. The critical strain lies within the range of experimentally observed strain values, and we therefore predict that strain is at least partly responsible for the sample-dependent experimental observations.

description: The use of carbon nanoparticles and graphene in composite materials has created a foundational shift in enhancing performance across mechanical, thermal, and electrical properties. Such applications are vital in the aerospace industry. However, there has not been such a focus on the material use for reducing radar cross section (RCS). Historically, RCS is minimized by designing sharp geometric shapes to deflect or dissipate the incoming electromagnetic waves away from the receiving antenna. However, these designs are not always optimized for aerodynamics. The goal of this research is to understand the application of composite materials and specifically carbon nanotubes (CNTs) to reduce RCS.

Using modeling and simulation software to design the experiment, it was found that using CNT composite materials can reduce the RCS by up to 74.1% for a flat plate, single point waveform across 0.1 GHz to 9 GHz. For a flat plate with a 360 degree horizontal waveform, CNTs have been measured to decrease the maximum RCS by 86.7% at 2.3 GHz. Lastly, for a model of an Airbus A380 with a 360 degree spherical waveform, the RCS has been measured to reduce the maximum by 79% at 2.8 GHz.

description: We introduce a simple yet effective early fusion method for crop yield prediction that handles multiple input modalities with different temporal and spatial resolutions. We use high-resolution crop yield maps as ground truth data to train crop and machine learning model agnostic methods at the sub-field level. We use Sentinel-2 satellite imagery as the primary modality for input data with other complementary modalities, including weather, soil, and DEM data. The proposed method uses input modalities available with global coverage, making the framework globally scalable. We explicitly highlight the importance of input modalities for crop yield prediction and emphasize that the best-performing combination of input modalities depends on region, crop, and chosen model.

description: It is demonstrated within the dibaryon-induced model for $NN$ interaction that $pp$ scattering in $P$ waves is governed mainly by the production of the intermediate dibaryon resonances. Two dibaryon resonances with a mass of about 2200 MeV discovered recently by the ANKE-COSY Collaboration are shown to determine both elastic $pp$ phase shifts and inelasticities in the $^3P_0$ and $^3P_2$-$^3F_2$ channels from zero energy up to $T_p=0.7$-$0.9$ GeV. It is also demonstrated clearly that the $^3P_0$ dibaryon plays a decisive role in near-threshold neutral pion production in $pp$ collisions which is poorly understood to date. The missing dibaryon contribution is found to be the very possible reason for the failure of traditional approaches to explain near-threshold $π^0$ production.

We consider a compact and low-cost setup based on a two-crystal scheme with Type-I phase matching. We study the effect of the pump coherence time over the entangled state visibility and over the violation of Bell's inequality, as a function of the crystals length. The full density matrix is reconstructed by quantum tomography. The proposed theoretical model is verified using a purification protocol based on a compensation crystal.

Our surface transportation infrastructure and the public who use it are becoming increasingly vulnerable to severe weather conditions. Statistics show that 24% of all United States highway crashes are weather-related and each year, nearly 7,400 people are killed and over 673,000 people are injured in these crashes. The National Highway Traffic Safety Administration (NHTSA) estimates the average cost per crash in 2000 to be $14,100 (Pisano et al. 2008). Weather-related crashes are defined by the Federal Highway Administration (FHWA) Road Weather Management program as those that occur in the presence of rain, sleet, snow, fog, wet pavement, snowy/slushy pavement, and/or icy pavement. Current methods to mitigate the impacts of these severe conditions include advisory information disseminated to travelers via local media, control options such as closing roads, and treatment operations that include snow removal. Decision support systems geared for a diverse group of end-users are becoming more widely implemented to combat the forces of nature. These systems can integrate atmospheric variables such as numerical weather prediction models and road pavement temperature with the resources available to a given municipality to produce a recommended course of action to ensure safety and efficiency. In addition, a connected system of vehicles that monitor road conditions and communicate with one another, in order to provide alerts of hazardous conditions ahead, promises to be a vital component of these systems. Decision support systems and connected vehicle technology represent the newest emerging technologies that will impact the future of intelligent transportation systems.

description: We use an improved wavelet analysis technique to reconstruct the $(U,V,W)$ velocity distribution for $\sim 250000$ stars from Gaia DR2, residing in the solar neighborhood of $200$~pc. The 2D wavelet transforms for three bivariate distributions $(U,V)$, $(U,W)$, and $(V,W)$ were investigated. Though most of currently known (low-velocity) stellar moving groups are densely overlapped in these diagrams, our analysis allowed to detect and disentangle about twenty statistically significant 3D groups of stars with high velocities. Most of them appear new. We also discuss the issue of correct noise thresholding in the wavelet transform and highlight the importance of using a global rather than local statistic for that. Using of a local significance measure may lead to an overstated statistical confidence for individual patterns due to the effect of multiple testing.

Using molecular dynamics simulations of a model glass-former we identify clusters of cooperatively jumping particles. We find string-like clusters whose size is power-law distributed not only close to T_c but for ALL temperatures below T_c, indicating self-organized criticality which we interpret as a freezing in of critical behavior.

description: We study two-point functions of symmetric traceless local operators in the bulk of de Sitter spacetime. We derive the Källén-Lehmann spectral decomposition for any spin and show that unitarity implies its spectral densities are nonnegative. In addition, we recover the Källén-Lehmann decomposition in Minkowski space by taking the flat space limit. Using harmonic analysis and the Wick rotation to Euclidean Anti de Sitter, we derive an inversion formula to compute the spectral densities. Using the inversion formula, we relate the analytic structure of the spectral densities to the late-time boundary operator content. We apply our technical tools to study two-point functions of composite operators in free and weakly coupled theories. In the weakly coupled case, we show how the Källén-Lehmann decomposition is useful to find the anomalous dimensions of the late-time boundary operators. We also derive the Källén-Lehmann representation of two-point functions of spinning primary operators of a Conformal Field Theory on de Sitter.

description: The ionizing radiation of massive stars sculpts the surrounding neutral gas into pillar-like structures. Direct signatures of star formation through outflows and jets are observed in these structures, typically at their tips. Recent numerical simulations have suggested that this star formation could potentially be triggered by photoionising radiation, driving compressive modes of turbulence in the pillars. In this study we use recent high-resolution ALMA observations of $^{12}\mathrm{CO}$, $^{13}\mathrm{CO}$, and $\mathrm{C}^{18} \mathrm{O}, \; J = 2-1$ emission to test this hypothesis for pillars in the Carina Nebula. We analyse column density and intensity-weighted velocity maps, and subtract any large-scale bulk motions in the plane of the sky to isolate the turbulent motions. We then reconstruct the dominant turbulence driving mode in the pillars, by computing the turbulence driving parameter $b$, characterised by the relation $σ_{ρ/ρ_0} = b \mathcal{M}$ between the standard deviation of the density contrast $σ_{ρ/ρ_0}$ (with gas density $ρ$ and its average $ρ_0$) and the turbulent Mach number $\mathcal{M}$. We find values of \mbox{$b\sim0.7$--$1.0$} for most of the pillars, suggesting that predominantly compressive modes of turbulence are driven in the pillars by the ionising radiation from nearby massive stars. We find that this range of $b$ values can produce star formation rates in the pillars that are a factor $\sim 3$ greater than with $b \sim 0.5$, a typical average value of $b$ for spiral-arm molecular clouds. Our results provide further evidence for the potential triggering of star formation in pillars through compressive turbulent motions.

Our surface transportation infrastructure and the public who use it are becoming increasingly vulnerable to severe weather conditions. Statistics show that 24% of all United States highway crashes are weather-related and each year, nearly 7,400 people are killed and over 673,000 people are injured in these crashes. The National Highway Traffic Safety Administration (NHTSA) estimates the average cost per crash in 2000 to be $14,100 (Pisano et al. 2008). Weather-related crashes are defined by the Federal Highway Administration (FHWA) Road Weather Management program as those that occur in the presence of rain, sleet, snow, fog, wet pavement, snowy/slushy pavement, and/or icy pavement. Current methods to mitigate the impacts of these severe conditions include advisory information disseminated to travelers via local media, control options such as closing roads, and treatment operations that include snow removal. Decision support systems geared for a diverse group of end-users are becoming more widely implemented to combat the forces of nature. These systems can integrate atmospheric variables such as numerical weather prediction models and road pavement temperature with the resources available to a given municipality to produce a recommended course of action to ensure safety and efficiency. In addition, a connected system of vehicles that monitor road conditions and communicate with one another, in order to provide alerts of hazardous conditions ahead, promises to be a vital component of these systems. Decision support systems and connected vehicle technology represent the newest emerging technologies that will impact the future of intelligent transportation systems.

description: We present commissioning data from the OSIRIS integral field spectrograph (IFS) on the Keck II 10 m telescope that demonstrate the utility of adaptive optics IFS spectroscopy in studying faint close-in sub-stellar companions in the haloes of bright stars. Our R~2000 J- and H-band spectra of the sub-stellar companion to the 1-10 Myr-old GQ Lup complement existing K-band spectra and photometry, and improve on the original estimate of its spectral type. We find that GQ Lup B is somewhat hotter (M6-L0) than reported in the discovery paper by Neuhauser and collaborators (M9-L4), mainly due to the surface-gravity sensitivity of the K-band spectral classification indices used by the discoverers. Spectroscopic features characteristic of low surface gravity objects, such as lack of alkali absorption and a triangular H-band continuum, are indeed prominent in our spectrum of GQ Lup B. The peculiar shape of the H-band continuum and the difference between the two spectral type estimates is well explained in the context of the diminishing strength of H2 collision induced absorption with decreasing surface gravity, as recently proposed for young ultra-cool dwarfs by Kirkpatrick and collaborators. Using our updated spectroscopic classification of GQ Lup B and a re-evaluation of the age and heliocentric distance of the primary, we perform a comparative analysis of the available sub-stellar evolutionary models to estimate the mass of the companion. We find that the mass of GQ Lup B is 0.010-0.040 Msun. Hence, it is unlikely to be a wide-orbit counterpart to the known radial-velocity extrasolar planets, whose masses are < 0.015 Msun. Instead, GQ Lup A/B is probably a member of a growing family of very low mass ratio widely separated binaries discovered through high-contrast imaging.

description: Recently, attention has turned to the issue of the ensemble dependence of fluctuation induced forces. As a noteworthy example, in $O(n)$ systems the statistical mechanics underlying such forces can be shown to differ in the constant $\vec{M}$ magnetic canonical ensemble (CE) from those in the widely-studied constant $\vec{h}$ grand canonical ensemble (GCE). Here, the counterpart of the Casimir force in the GCE is the \textit{Helmholtz} force in the CE. Given the difference between the two ensembles for finite systems, it is reasonable to anticipate that these forces will have, in general, different behavior for the same geometry and boundary conditions. Here we present some exact results for both the Casimir and the Helmholtz force in the case of the one-dimensional Ising model subject to periodic and antiperiodic boundary conditions and compare their behavior. We note that the Ising model has recently being solved in Phys.Rev. E {\bf 106} L042103(2022), using a combinatorial approach, for the case of fixed value $M$ of its order parameter. Here we derive exact result for the partition function of the one-dimensional Ising model of $N$ spins and fixed value $M$ using the transfer matrix method (TMM); earlier results obtained via the TMM were limited to $M=0$ and $N$ even. As a byproduct, we derive several specific integral representations of the hypergeometric function of Gauss. Using those results, we rigorously derive that the free energies of the CE and grand GCE are related to each other via Legendre transformation in the thermodynamic limit, and establish the leading finite-size corrections for the canonical case, which turn out to be much more pronounced than the corresponding ones in the case of the GCE.
