description: Self-consistent model grids of brown dwarfs involve complex physics and chemistry, and are often computed using proprietary computer codes, making it challenging to identify the reasons for discrepancies between model and data as well as between the models produced by different research groups. In the current study, we demonstrate a novel method for analyzing brown dwarf spectra, which combines the use of the Sonora, AMES-Cond and HELIOS model grids with the supervised machine learning method of the random forest. Besides performing atmospheric retrieval, the random forest enables information content analysis of the three model grids as a natural outcome of the method, both individually on each grid and by comparing the grids against one another, via computing large suites of mock retrievals. Our analysis reveals that the different choices made in modelling the alkali line shapes hinder the use of the alkali lines as gravity indicators. Nevertheless, the spectrum longward of 1.2 micron encodes enough information on the surface gravity to allow its inference from retrieval. Temperature may be accurately and precisely inferred independent of the choice of model grid, but not the surface gravity. We apply random forest retrieval to three objects: the benchmark T7.5 brown dwarf GJ 570D; and Epsilon Indi Ba (T1.5 brown dwarf) and Bb (T6 brown dwarf), which are part of a binary system and have measured dynamical masses. For GJ 570D, the inferred effective temperature and surface gravity are consistent with previous studies. For Epsilon Indi Ba and Bb, the inferred surface gravities are broadly consistent with the values informed by the dynamical masses.

description: In this analysis we compare WTP estimates of responses separately modelling choice sets of forced choices from those of unforced choices in order to measure the effect of forced choice in Choice experiment. This comparison is done while still maintain constant task complexity and evaluated in WTP space. We find evidence to suggest that individual WTP are different in forced and unforced choice sets and in joint tests for parameter equality.

description: This paper investigates the relationship between WIC program participation and purchases of WIC related food. Nielsen Homescan data 2008 to 2010 provide unique information with food expenditures including details on household’s demographics and reported WIC participation status. Using scanner data, we assess how participation in the WIC program relates to food expenditures by WIC eligible (but not participating) and by WIC participating households. The research includes a comparison of select food purchases between eligible WIC reporting and eligible WIC not-reporting households during the period of introduction of changes in the WIC food package. Specific foods and food groups of interest for the analysis include whole grain products.

description: Focusing on semiclassical systems, we show that the parametrically long exponential growth of out-of-time order correlators (OTOCs), also known as scrambling, does not necessitate chaos. Indeed, scrambling can simply result from the presence of unstable fixed points in phase space, even in a classically integrable model. We derive a lower bound on the OTOC Lyapunov exponent which depends only on local properties of such fixed points. We present several models for which this bound is tight, i.e. for which scrambling is dominated by the local dynamics around the fixed points. We propose that the notion of scrambling be distinguished from that of chaos.

description: We demonstrate a tunable negative differential resistance controlled by spin blockade in single electron transistors. The single electron transistors containing a few electrons and spin polarized source and drain contacts were formed in GaAs/GaAlAs heterojunctions using metallic gates. Coulomb blockade measurements performed as a function of applied source-drain bias, electron number and magnetic field reveal well defined regimes where a decrease in the current is observed with increasing bias. We establish that the origin of the negative differential regime is the spin-polarized detection of electrons combined with a long spin relaxation time in the dot. These results indicate new functionalities that may be utilized in nano-spintronic devices in which the spin state is electro-statically controlled via the electron occupation number.

description: Testing the equality of two means is a fundamental inference problem. For high-dimensional data, the Hotelling’s T2-test either performs poorly or becomes inapplicable. Several modifications have been proposed to address this issue. However, most of them are based on asymptotic normality of the null distributions of their test statistics which inevitably requires strong assumptions on the covariance. We study this problem thoroughly and propose an L2-norm based test that works under mild conditions and even when there are fewer observations than the dimension. Specially, to cope with general nonnormality of the null distribution we employ the Welch–Satterthwaite χ2-approximation. We derive a sharp upper bound on the approximation error and use it to justify that χ2-approximation is preferred to normal approximation. Simple ratio-consistent estimators for the parameters in the χ2-approximation are given. Importantly, our test can cope with singularity or near singularity of the covariance which is commonly seen in high dimensions and is the main cause of nonnormality. The power of the proposed test is also investigated. Extensive simulation studies and an application show that our test is at least comparable to and often outperforms several competitors in terms of size control, and the powers are comparable when their sizes are.

description: We analyze large gauge invariance in combined nonabelian and thermal QFT and their physical consequences for D=3 effective actions. After briefly reviewing the structure of bundles and large gauge transformations that arise in non-simply connected 3-manifolds and gauge groups, we discuss their connections to Chern-Simons terms and Wilson-Polyakov loops. We then provide an invariant characterization of the ``abelian'' fluxes encountered in explicit computations of finite temperature effective actions. In particular we relate, and provide explicit realizations of, these fluxes to a topological index that measures the obstruction to global diagonalization of the loops around compactified time. We also explore the fate of, and exhibit some everywhere smooth, large transformations for non-vanishing index in various topologies.

description: This study examined the effects of China’s grain subsidy program, the largest food self-sufficiency project in the developing countries, on grain-sown areas within a context of liquidity constraints. A large household level panel was used to evaluate how the subsidy affects the cultivation schedule of farm households through the relaxation of households’ liquidity con¬straints. Results suggest that in general, the grain subsidy program significantly improved farm households’ grain planting areas for liquidity-constrained households. This finding provides a more comprehensive understanding of the effects of China’s grain subsidy than previous studies

description: A nonlinear chain driven by one end may propagate energy in the forbidden band gap by means of nonlinear modes. For harmonic driving at a given frequency, the process ocurs at a threshold amplitude by sudden large energy flow, that we call nonlinear supratransmission. The bifurcation of energy transmission is demonstrated numerically and experimentally on the chain of coupled pendula (sine-Gordon and nonlinear Klein-Gordon equations) and sustained by an extremely simple theory.

description: Measurements of the Hubble constant, and more generally measurements of the expansion rate and distances over the interval $0 < z < 1$, appear to be inconsistent with the predictions of the standard cosmological model ($Λ$CDM) given observations of cosmic microwave background temperature and polarization anisotropies. Here we consider a variety of types of departures from $Λ$CDM that could, in principle, restore concordance among these datasets, and we explain why we find almost all of them unlikely to be successful. We single out the set of solutions that increase the expansion rate in the decade of scale factor expansion just prior to recombination as the least unlikely. These solutions are themselves tightly constrained by their impact on photon diffusion and on the gravitational driving of acoustic oscillations of the modes that begin oscillating during this epoch -- modes that project on to angular scales that are very well measured. We point out that a general feature of such solutions is a residual to fits to $Λ$CDM, like the one observed in Planck power spectra. This residual drives the modestly significant inferences of angular-scale dependence to the matter density and anomalously high lensing power, puzzling aspects of a data set that is otherwise extremely well fit by $Λ$CDM.

description: This paper presents a structured decomposition approach to Fermat’s Last Theorem (FLT), demonstrating that any integer raised to a prime power follows a unique breakdown governed by Pascal’s Triangle and factorial-based terms. This decomposition inherently prevents recombination into two valid power sums, thereby establishing a direct number-theoretic proof of FLT. By showing that the structured decomposition follows a recurrence relation that enforces modular constraints, we provide an elementary obstruction to the existence of integer solutions for  when . This method offers a new perspective on the theorem and provides a potentially original insight into Fermat’s claimed “elegant proof

Using real-time CO₂ monitoring and a custom risk assessment tool, the study assessed Purdue University buildings—including Mackey Arena and two dining courts—as well as a senior living facility with UV disinfection. The research quantified Equivalent Clean Airflow (VECAi) and compared it to ASHRAE 241 targets under Infection Risk Management Mode (IRMM). Most assessed spaces failed to meet VECAi thresholds, highlighting critical ventilation and filtration gaps. The study recommends practical engineering interventions like improved filtration, outdoor airflow, and GUV systems. The risk tool developed serves as a decision-making aid for building compliance with ASHRAE 241.

description: Exceptional field theories yield duality covariant formulations of supergravity. We show that they provide a highly efficient tool to compute the Kaluza-Klein mass spectra associated to compactifications around various background geometries relevant for string theory and holographic applications. This includes geometries with little to no remaining symmetries, hardly accessible to standard methods. As an illustration, we work out the masses of some higher Kaluza-Klein multiplets around warped geometries corresponding to some prominent ${\cal N} = 2$ supersymmetric AdS vacua in maximal supergravity.

description: In the framework of the QCD string approach it is shown that the spin-averaged masses $\bar{M}(nL)$ of all low-lying light mesons are well described using the string tension $σ$ as the only parameter. The Regge slope $α'_L$ and the intercept $α_L(0)$ of the Regge L-trajectory for $\bar{M}(nL)$ are calculated analytically and turn out to be $α'_L = 0.80$ GeV${}^{-2}$ (for $L \leq 4$) and $α_L(0) = -0.34$, in good agreement with the experimental data: $α'_{L {\rm exp}} = 0.81 \pm 0.01$ GeV${}^{-2}$, $α_{L {\rm exp}}(0) = -0.30 \pm 0.02$. To obtain this strong agreement with the data the nonperturbative quark self-energy contributions to the meson masses must be taken into account, which appeared to be large and negative for small values of L, and are even for larger values of L important for a close fit. From the present analysis of the meson spectra the restriction $α_s \leq 0.40$ on the strong coupling is required.

description: With a day-side temperature in excess of 4500K, comparable to a mid-K-type star, KELT-9b is the hottest planet known. Its extreme temperature makes KELT-9b a particularly interesting test bed for investigating the nature and diversity of gas giant planets. We observed the transit of KELT-9b at high spectral resolution (R$\sim$94,600) with the CARMENES instrument on the Calar Alto 3.5-m telescope. Using these data, we detect for the first time ionized calcium (CaII triplet) absorption in the atmosphere of KELT-9b; this is the second time that CaII has been observed in a hot Jupiter. Our observations also reveal prominent H$α$ absorption, confirming the presence of an extended hydrogen envelope around KELT-9b. We compare our detections with an atmospheric model and find that all four lines form between atmospheric temperatures of 6100 K and 8000 K and that the CaII lines form at pressures between 10 and 50 nbar while the H$α$ line forms at a lower pressure ($\sim$6 nbar), higher up in the atmosphere. The altitude that the core of H$α$ line forms is found to be $\sim$1.4 R$_{p}$, well within the planetary Roche lobe ($\sim$1.9 R$_{p}$). Therefore, rather than probing the escaping upper atmosphere directly, the H$α$ line and the other observed Balmer and metal lines serve as atmospheric thermometers enabling us to probe the planet's temperature profile, thus energy budget.

description: Die Geschichte des Museums für Naturkunde Berlin hat eine umfangreiche Bildersammlung hervorgebracht. Sie ist heute Teil der Historischen Arbeitsstelle, dem zentralen Archiv des Museums, welches sich im Laufe des 20. Jahrhunderts formierte. Zunächst waren es vor allem Einzelpersonen, die vor dem Hintergrund von biologiegeschichtlichen Fragestellungen historische Materialien zu katalogisieren begannen. Ihr Handeln hat sich in die „Bilder der Natur“ eingeschrieben und eine Reihe von Ordnungssystemen hervorgebracht, deren jeweilige Charakteristik unterschiedliche Zugangsweisen zu den Bilddokumenten bedingt. Sie folgen dem Prinzip von Liste, Kartei und Datenbank. Eine Beschäftigung mit diesen Medien des Sammelns und Adressierens erlaubt eine Zeitreise sowohl in die Geschichte der Historischen Bild- und Schriftgutsammlungen als auch zu den historiographischen Ansätzen ihrer Akteur:innen. Die hier erstmals vorgestellte Arbeitskartei der Historischen Bildsammlungen verbindet als „boundary object“ Blicke und Gewerke und verdeutlicht die naturkundliche Notwendigkeit einer operablen Verweisstruktur zwischen Sammlungsobjekten, Bildern und Papier. Zudem ist sie auch im Sinne eines „historiographischen Objekts“ wirksam. Die durch die Bilderkartei bestimmten Wege des Suchens, Verweisens und Verknüpfens von Informationen gestalten entscheidend die Formen historischen Erzählens mit. Dieser Aufsatz stellt folglich einen Beitrag zur Historiographie wissenschaftlicher Sammlungen dar. Er perspektiviert Sammlungsgeschichte als Geschichte ihrer Ordnungssysteme.

description: We investigate applying convolutional neural network (CNN) architecture to facilitate aerial hyperspectral scene understanding and present a new hyperspectral dataset-AeroRIT-that is large enough for CNN training. To date the majority of hyperspectral airborne have been confined to various sub-categories of vegetation and roads and this scene introduces two new categories: buildings and cars. To the best of our knowledge, this is the first comprehensive large-scale hyperspectral scene with nearly seven million pixel annotations for identifying cars, roads, and buildings. We compare the performance of three popular architectures - SegNet, U-Net, and Res-U-Net, for scene understanding and object identification via the task of dense semantic segmentation to establish a benchmark for the scene. To further strengthen the network, we add squeeze and excitation blocks for better channel interactions and use self-supervised learning for better encoder initialization. Aerial hyperspectral image analysis has been restricted to small datasets with limited train/test splits capabilities and we believe that AeroRIT will help advance the research in the field with a more complex object distribution to perform well on. The full dataset, with flight lines in radiance and reflectance domain, is available for download at https://github.com/aneesh3108/AeroRIT. This dataset is the first step towards developing robust algorithms for hyperspectral airborne sensing that can robustly perform advanced tasks like vehicle tracking and occlusion handling.

description: Die Geiseltal-Sammlung des Zentralmagazins Naturwissenschaftlicher Sammlungen (ZNS) der Martin-Luther-Universität Halle-Wittenberg stellt eine wertvolle geowissenschaftliche Forschungsressource dar und ist seit 2011 als national wertvolles Kulturgut eingetragen. Die Fossilien bieten einen detaillierten Einblick in die eozäne Tier- und Pflanzenwelt vor 42,5 bis 47,5 Millionen Jahren, aber auch auf den geologischen Ablagerungsraum einer küstennahen Sumpflandschaft. In den kohledominierten Sedimenten des Geiseltals (Sachsen-Anhalt) wurde von Mitte der 1920er Jahre bis zum Ende des 20. Jahrhunderts kommerzieller Braunkohlebergbau mit wissenschaftlichen Ausgrabungen kombiniert. Die seit fast 100 Jahren in Halle (Saale) gelagerte Geiseltal-Sammlung verbindet wissenschaftliches Potential aus geowissenschaftlicher, biologischer, chemischer, museologischer und historischer Sicht. Im Rahmen des deutsch-irischen Dissertationsprojektes „Taphonomy of the Eocene Geiseltal Konservat-Lagerstätte, Germany“ werden die fossilen Wirbeltiere untersucht. In dem vorliegenden Beitrag präsentieren wir Forschungsansätze, um die außergewöhnliche Erhaltung der Fossilien besser zu verstehen. Es wurden hierfür exemplarisch 180 Anuren (Froschlurche) auf ihre Ausrichtung im Sediment sowie auf Skelettvollständigkeit und -artikulation untersucht. In weiteren Untersuchungen ist die chemische Analyse der beprobten, potentiellen Weichteilüberreste und der die Froschlurche einbettenden Sedimentschichten vorgesehen. Dieser Artikel gibt einen historischen Überblick zur Geiseltal-Sammlung und stellt die genannten Untersuchungsmethoden, vorläufige Resultate und die damit einhergehenden Vorzüge der Objektbearbeitung vor.

description: Substantial Government and industry effort has been directed at improving Australia's export performance in recent years and a considerable amount of research has been done into various issues impacting on export performance. There has been very little work done however, at the domestic end of the export chain, focusing on turning export opportunities into realities. While it is well recognised that a number of external factors have a considerable impact on access by Australian exporters to overseas markets, it is hypothesised that domestic arrangements (government and industry regulations, associated compliance costs and inefficient infrastructure) are also a major factor limiting the growth of agricultural exports. Industry surveys and several case study analyses were carried out in five agricultural export industries, with the intent of identifying and measuring domestic impediments to their entry into and development of overseas markets. In general it was found that some regulations comprised an unwarranted impediment, while other impediments identified were the result of 'myths' perpetuated through poor extension, or support services from Government and industry that did not meet exporter needs.
H$_2$ ortho-para spin conversion on inhomogeneous grain surfaces

description: We investigate the evolution of the ortho-to-para ratio of overall (gas + ice) H$_2$ via the nuclear spin conversion on grain surfaces coated with water ice under physical conditions that are relevant to star- and planet-forming regions. We utilize the rate equation model that considers adsorption of gaseous H$_2$ on grain surfaces which have a variety of binding sites with a different potential energy depth, thermal hopping, desorption, and the nuclear spin conversion of adsorbed H$_2$. It is found that the spin conversion efficiency depends on the H$_2$ gas density and the surface temperature. As a general trend, enhanced H$_2$ gas density reduces the efficiency, while the temperature dependence is not monotonic; there is a critical surface temperature at which the efficiency is the maximum. At low temperatures, the exchange of gaseous and icy H$_2$ is inefficient (i.e., adsorbed H$_2$ does not desorb and hinders another gaseous H$_2$ to be adsorbed), while at warm temperatures, the residence time of H$_2$ on surfaces is too short for the spin conversion. Additionally, the spin conversion becomes more efficient with lowering the activation barriers for thermal hopping. We discuss whether the spin conversion on surfaces can dominate over that in the gas-phase in star- and planet-forming regions. Finally, we establish a simple but accurate way to implement the H$_2$ spin conversion on grain surfaces in existing astrochemical models.

description: Pairing Correlations are studied numerically in the hole-doped spin-fermion model for cuprates. Simulations performed on up to 12x12 clusters provide robust indications of D-wave superconductivity away from half-filling. The pairing correlations are the strongest in the direction perpendicular to the dynamic stripe-like inhomogeneities that appear in the ground state at some densities. An optimal doping, where the correlations reach a maximum value, was observed at about 25% doping, in qualitative agreement with hight T_{c} cuprates' experiments. On the other hand, pairing correlations are suppressed by static stripe inhomogeneities.

 Dimensions. d= 4–7 mm, juvenile around 2.5 mm; s=32–48 (+s), juvenile 24.
 Description. Phaceloid corallum; corallites circular in outline; costosepta compact, straight; S1 and some of S2 reach center of calice, where their inner ends may fuse with trabecular or substyliform columella; remaining septa alternate in length and thickness; anastomoses common; wall septothecal.
 Remarks. According to Morycowa & Roniewicz (1990: 168) as well as based on the study of topotypes by the author, Cladophyllia furcifera Roemer has 3 cycles of septa in 6 systems, with the beginning of a fourth one. However, in the Jamaican specimens the number of septa can be slightly larger, corresponding to 4 complete cycles in 6 systems, but otherwise they agree well with Cladophyllia furcifera Roemer, 1888.

description: Tip-extending soft robots that "grow" via pneumatic eversion of their body material have demonstrated applications in exploration of cluttered environments. During growth, the motion and force of the robot tip can be controlled in three degrees of freedom using actuators that direct the tip in combination with extension. However, when reversal of the growth process is attempted by retracting the internal body material from the base, the robot body often responds by buckling rather than inverting the body material, making control of tip motion and force impossible. We present and validate a model to predict when buckling occurs instead of inversion, and we present an electromechanical device that can be added to a tip-extending soft robot to prevent buckling during retraction, restoring the ability of steering actuators to control the robot's motion and force during inversion. Using our retraction device, we demonstrate three previously impossible tasks: exploring different branches of a forking path, reversing growth while applying minimal force on the environment, and bringing back environment samples to the base.

Borexino: A real time liquid scintillator detector for low energy solar neutrino study
Creators: name: Miramonti, Lino
Publisher: name: arXiv
Year: 2002
Subjects: subject: High Energy Physics - Experiment (hep-ex)
subject: FOS: Physical sciences

description: Borexino is a large unsegmented calorimeter featuring 300 tons of liquid scintillator, contained in a 8.5 meter nylon vessel, viewed by 2200 PMTs. The main goal of Borexino is the study, in real time, of low energy solar neutrinos, and in particular, the monoenergetic neutrinos coming from $^7Be$, which is one of the missing links on the solar neutrino problem. The achievement of high radiopurity level, in the order of $10^{-16} g/g$ of U/Th equivalent, necessary to the detection of the low energy component of the solar neutrino flux, was proved in the Borexino prototype: the Counting Test Facility. The detector is located underground in the Laboratori Nazionali del Gran Sasso in the center of Italy at 3500 meter water equivalent depth. In this paper the science and technology of Borexino are reviewed and its main capabilities are presented.
