description: Observations of light isotopes in cosmic rays provide valuable information on their origin and propagation in the Galaxy. Using the data collected by the AMS-01 experiment in the range ~0.2-1.5 GeV/nucleon, we compare the measurements on 1H, 2H, 3He, and 4He with calculations for interstellar propagation and solar modulation. These data are described well by a diffusive-reacceleration model with parameters that match the B/C ratio data, indicating that He and heavier nuclei such as C-N-O experience similar propagation histories. Close comparisons are made within the astrophysical constraints provided by the B/C ratio data and within the nuclear uncertainties arising from errors in the production cross-section data. The astrophysical uncertainties are expected to be dramatically reduced by the data upcoming from AMS-02, so that the nuclear uncertainties will likely represent the most serious limitation on the reliability of the model predictions. On the other hand, we find that secondary-to-secondary ratios such as 2H/3He, 6Li/7Li or 10B/11B are barely sensitive to the key propagation parameters and can represent a useful diagnostic test for the consistency of the calculations.

description: Recently, Dvali, Gomez, and Mukhanov have investigated a classical lambda phi^4 model with external source and without mass and they have clarified that there are underlying renormalization group structure, including the phenomenon of the dimensional transmutation, at purely classical level. Especially when the coupling lambda is negative, the classical beta function shows the property of asymptotic freedom as in QCD. In this paper, we investigate the lambda phi^4 model with mass, and clarify the role of the mass. The obtained classical beta function is identical with that of the massless lambda phi^4 model up to the corrections of the ratio of the IR cutoff to UV cutoff, and describes the renormalization flow same as the massless theory. We also found that the dynamically generated scale of massive theory is larger than that of massless theory, which could be due to the screening effect of the mass term.

description: An updated and annotated catalogue of the vascular plants reported for the Arezzo administrative province (eastern Tuscany, Italy) is presented. The study tries to fill the gaps existing in the data at the sub-regional administrative scale, addressing relevant taxonomic and distribution issues, important not only at local level. The catalogue was compiled by gathering all the botanical information from various source types (old and recent floras, vegetation data, taxonomic studies, floristic and chromosome number reports, herbarium data, landscape studies, original field observations). More than 32,000 records were critically examined, georeferenced and stored in a floristic database. For many controversial taxa, considerations and case-by-case comments are reported in explanatory notes. A distribution map of report locations and a map of floristic information intensity (number of records per location) are provided. The total number of taxa registered is 2082, of which four Lycophytes, 42 Ferns and fern allies, 47 Gymnosperms and 1989 Angiosperms. In the total list, 1759 taxa were confirmed after 1950, 126 recorded before 1950, 116 considered inquirendae and 81 excludendae. Amongst the taxa confirmed after 1950, 1518 are native, 13 cryptogenic and 228 alien, of which 104 considered cultivated and 29 invasive for the Arezzo province. Data were analysed in relation to number of families, consistence of native and alien flora, chorological and general conservation aspects.

description: Quantum gravity is extended to include purely virtual "cloud sectors", which allow us to define a complete set of point-dependent observables, including a gauge invariant metric and gauge invariant matter fields, and calculate their off-shell correlation functions perturbatively. The ordinary on-shell correlation functions and the $S$ matrix elements are unaffected. Each extra sector is made of a cloud field, its anticommuting partner, a "cloud-fixing" function and a cloud Faddeev-Popov determinant. The additional fields are purely virtual, to ensure that no ghosts propagate. The extension is unitary. In particular, the off-shell, diagrammatic version of the optical theorem holds. The one-loop two-point functions of dressed scalars, vectors and gravitons are calculated. Their absorptive parts are positive, cloud independent and gauge independent, while they are unphysical if non purely virtual clouds are used. We illustrate the differences between our approach to the problem of finding a complete set of observables in quantum gravity and other approaches available in the literature.

Description. Massive sponge with 13 cm long x 16 wide coverage, it presents lobes 1–2 cm high and 1.3–1.9 cm in diameter. Color in life is orange-brown or purple-brown (Figure 7A). Surface is irregular and smooth, but when observed under the microscope there are notable groups of spicules that protrude from it (Figure 7B). The sponge is of compressible and elastic consistency. The skeleton is formed by a tangential reticulate ectosome containing fibers of multiple mycalostyles. The choanosome contains tracts formed by mycalostyles that arise from the base of the sponge and come to exceed the surface assimilating small brushes. Spicules are mycalostyles, isochelae, sigma and anisochelae in two size categories, toxa and raphides (Figure 7C–I).
Ecological notes. The species was found covering large rocks and calcareous algae up to 16 m depth.
Distribution and previous records. The species was described by Carballo & Cruz-Barraza in 2010 from the Mexican Pacific coast, and has also been reported from Punta Amapala in El Salvador (Trejo & Segovia 2024). Here we extend its distribution in the country to Los Cóbanos (Table 12).
Remarks. Our specimens coincide with the original description in skeletal arrangement and spicule composition, above all, on the presence of anisochela in two categories and palmate isochelae (Carballo & Cruz-Barraza 2010), this last characteristic was determinant for the identification of M. ramulosa above all Mycale species reported for the Eastern Tropical Pacific. Color in life of the specimens was brownish orange and brownish purple, and they were found with massive and incrusting morphologies.

description: The Giardino Inglese of the Reggia di Caserta is among the most important and ancient gardens in Italy. A survey of vegetation was carried out, and a collection catalogue was produced using updated nomenclature and Angiosperm Phylogeny Group (APG) IV criteria classification. The data from survey were georeferenced in a GIS environment. For each species, the conservation status at world level as per International Union for Conservation of Nature (IUCN) and Botanic Gardens Conservation International (BGCI), the phytosanitary status, and the number of individuals were evaluated. Two synthetic indices were created that allow the evaluation of collection’s erosion risk (ER). In the analysis, each species is placed in a specific quadrant indicating its level of erosion risk, and a priority score (PS) allows the evaluation of the priorities of any conservations interventions. The collection consists of 235 species, and approximately 65% of these are reported in IUCN Red List. 1671 individuals were registered. The database and the ER assessment allows the future development of tools for the management of the site. The Giardino Inglese is a garden of collections and a conservation basin for historical and monumental specimens of many species, some of which are subject to protection.

description: A new high symmetry Mn12 oxocarboxylate cluster [Mn12O12(CN-o-C6H4CO2)12(CH3CO2)4(H2O)4]*8CH2Cl2 (1) with mixed carboxylate ligands is reported. It was synthesized by the standard carboxylate substitution method. 1 crystallizes in the tetragonal space group I41/a. Complex 1 contains a [Mn12O12] core with eight CN-o-C6H4CO2 ligands in the axial positions, four CH3CO2 and four CN-o-C6H4CO2 those in equatorial positions. Four H2O molecules are bonded to four Mn atoms in an alternating up, down, up, down arrangement indicating 1:1:1:1 isomer. The Mn12 molecules in 1 are self-assembled by complementary hydrogen C-H...N bonds formed with participation of the axial o-cyanobenzoate ligands of the adjacent Mn12 clusters. The lattice solvent molecules (CH2Cl2) are weakly interacted with Mn12 units that results in solvent loss immediately after removal of the crystals from the mother liquor. The electronic structure and the intramolecular exchange parameters have been calculated. Mn 3d bands of 1 are rather broad and center of gravity of the bands shifts down from Fermi level. The overlap between Mn 3d bands and 2p ones of the oxygen atoms from carboxylate bridges is higher than in the parent Mn12-acetate cluster. These changes in electronic structure provide significant difference in the exchange interactions in comparison to Mn12-acetate. The magnetic properties have been studied on a dried (solvent-free) polycrystalline sample of 1. The dc magnetic susceptibility measurements in the 2-300 K temperature range support a high-spin ground state (S = 10).

description: In the field of monitored quantum circuits, it has remained an open question whether finite-time protocols for preparing long-range entangled states lead to phases of matter which are stable to gate imperfections, which can convert projective into weak measurements. Here we show that in certain cases, long-range entanglement persists in the presence of weak measurements, and gives rise to novel forms of quantum criticality. We demonstrate this explicitly for preparing the two-dimensional Greenberger-Horne-Zeilinger cat state and the three-dimensional toric code as minimal instances. In contrast to the monitored random unitary circuits, In contrast to random monitored circuits, our circuit of gates and measurements is deterministic; the only randomness is in the measurement outcomes. We show how the randomness in these weak measurements allows us to track the solvable Nishimori line of the random-bond Ising model, rigorously establishing the stability of the glassy long-range entangled states in two and three spatial dimensions. Away from this exactly solvable construction, we use hybrid tensor network and Monte Carlo simulations to obtain a nonzero Edwards-Anderson order parameter as an indicator of long-range entanglement in the two-dimensional scenario. We argue that our protocol admits a natural implementation in existing quantum computing architectures, requiring only a depth-3 circuit on IBM's heavy-hexagon transmon chips.

description: In the race to build scalable quantum computers, minimizing the resource consumption of their full stack to achieve a target performance becomes crucial. It mandates a synergy of fundamental physics and engineering: the former for the microscopic aspects of computing performance, and the latter for the macroscopic resource consumption. For this we propose a holistic methodology dubbed Metric-Noise-Resource (MNR) able to quantify and optimize all aspects of the full-stack quantum computer, bringing together concepts from quantum physics (e.g., noise on the qubits), quantum information (e.g., computing architecture and type of error correction), and enabling technologies (e.g., cryogenics, control electronics, and wiring). This holistic approach allows us to define and study resource efficiencies as ratios between performance and resource cost. As a proof of concept, we use MNR to minimize the power consumption of a full-stack quantum computer, performing noisy or fault-tolerant computing with a target performance for the task of interest. Comparing this with a classical processor performing the same task, we identify a quantum energy advantage in regimes of parameters distinct from the commonly considered quantum computational advantage. This provides a previously overlooked practical argument for building quantum computers. While our illustration uses highly idealized parameters inspired by superconducting qubits with concatenated error correction, the methodology is universal -- it applies to other qubits and error-correcting codes -- and provides experimenters with guidelines to build energy-efficient quantum processors. In some regimes of high energy consumption, it can reduce this consumption by orders of magnitudes. Overall, our methodology lays the theoretical foundation for resource-efficient quantum technologies.

description: We present a detailed report of a measurement of the neutron $β$-asymmetry parameter $A_0$, the parity-violating angular correlation between the neutron spin and the decay electron momentum, performed with polarized ultracold neutrons (UCN). UCN were extracted from a pulsed spallation solid deuterium source and polarized via transport through a 7-T magnetic field. The polarized UCN were then transported through an adiabatic-fast-passage spin-flipper field region, prior to storage in a cylindrical decay volume situated within a 1-T $2 \times 2π$ solenoidal spectrometer. The asymmetry was extracted from measurements of the decay electrons in multiwire proportional chamber and plastic scintillator detector packages located on both ends of the spectrometer. From an analysis of data acquired during runs in 2008 and 2009, we report $A_0 = -0.11966 \pm 0.00089_{-0.00140} ^{+0.00123}$, from which we extract a value for the ratio of the weak axial-vector and vector coupling constants of the nucleon, $λ= g_A/g_V = -1.27590 \pm 0.00239_{-0.00377}^{+0.00331}$. Complete details of the analysis are presented.

description: Previous works have suggested that arbuscular mycorrhizal (AM) fungi can enhance the quality of plant products and fruits. Therefore, the aim of the present study was to investigate the effects of AM fungi on Cucumis melo plant growth, yield, fitness and fruit quality. Inoculated and uninoculated plants of two melon cultivars (Baggio and Expò) were grown in field under common agronomic practices. In addition, a greenhouse test was run on cv. Expò in order to assess the effects of AM inoculation on shoot, leaf and flower development in semi-controlled conditions. In comparison to controls, AM plants flowered earlier, produced more flowers and their pulp contained more sugars and carotenoids. The symbiosis also improved seed size and weight, as well as their germination and root elongation in the first stages of growth in field. Concluding, AM inoculation significantly improved fruit quality in field, under commercial production conditions, also leading to the development of seeds with higher germination rate and increasing plant fitness.

description: After finding a solution for the Hayward regular black hole (HRBH) in massive gravity, we embed the (3+1)-dimensional HRBHs both in massless and in massive gravities into (5+2)- and (6+3)-dimensional Minkowski spacetimes, respectively. Here, massive gravity denotes that a graviton acquires a mass holographically by broken momentum conservation in the HRBH. The original HRBH has no holographically added gravitons, which we call massless. Making use of newly found embedding coordinates, we obtain desired Unruh temperatures and compare them with the Hawking and local fiducial temperatures, showing that the Unruh effect for a uniformly accelerated observer in a higher dimensional flat spacetime is equal to the Hawking effect for a fiducial observer in a black hole spacetime. We also obtain freely falling temperatures of the HRBHs in massless and massive gravities seen by freely falling observers, which remain finite even at the event horizons while becoming the Hawking temperatures in asymptotic infinity.

description: Motivated by recent experiments measuring the spin transport in ultracold unitary atomic Fermi gases (Sommer et al., 2011; Sommer et al., 2011), we explore the theory of spin and heat transport in a three-dimensional spin-polarized atomic Fermi gas. We develop estimates of spin and thermal diffusivities and discuss magnetocaloric effects, namely the the spin Seebeck and spin Peltier effects. We estimate these transport coefficients using a Boltzmann kinetic equation in the classical regime and present experimentally accessible signatures of the spin Seebeck effect. We study an exactly solvable model that illustrates the role of momentum-dependent scattering in the magnetocaloric effects.

description: In order to achieve good performance and generalisability, medical image segmentation models should be trained on sizeable datasets with sufficient variability. Due to ethics and governance restrictions, and the costs associated with labelling data, scientific development is often stifled, with models trained and tested on limited data. Data augmentation is often used to artificially increase the variability in the data distribution and improve model generalisability. Recent works have explored deep generative models for image synthesis, as such an approach would enable the generation of an effectively infinite amount of varied data, addressing the generalisability and data access problems. However, many proposed solutions limit the user's control over what is generated. In this work, we propose brainSPADE, a model which combines a synthetic diffusion-based label generator with a semantic image generator. Our model can produce fully synthetic brain labels on-demand, with or without pathology of interest, and then generate a corresponding MRI image of an arbitrary guided style. Experiments show that brainSPADE synthetic data can be used to train segmentation models with performance comparable to that of models trained on real data.

description: Near the event horizon of a black hole, the effective theory is two dimensional conformal theory. Here we show that the holographic modes characterising this underlying conformal symmetry and the basic definition of entropy $S$ in statistical mechanics lead the equipartition law of energy. We also show that $S$ is proportional to the gravity action which suggests the emergent nature of gravity. This is further bolstered by expressing the generalised Smarr formula as a thermodynamic relation, $S = E/ 2T$, where $T$ is the Hawking temperature and $E$ is shown to be the Komar energy.

description: We study the autonomous systems of quadratic differential equations of the form $\dot{x}_i(t)=\mathbf{x}(t)^T \mathbf{A}_i \mathbf{x}(t) + \mathbf{v}_i^T \mathbf{x}(t)$ with $\mathbf{x}(t) = (x_1(t),x_2(t),\dots,x_i(t),\dots)$ which, in general, cannot be solved exactly. In the present paper, we present a subclass of analytically solvable quadratic systems, whose solution is realized through a multi-dimensional generalization of the inversion which transforms a quadratic system into a linear system. We provide a constructive algorithm which, on one hand, decides whether the system of differential equations is analytically solvable with the inversion transformation and, on the other hand, provides the solution. The presented results apply for arbitrary, finite number of variables.

description: We propose to build and operate a detector based on the emulsion film technology for the measurement of the gravitational acceleration on antimatter, to be performed by the AEgIS experiment (AD6) at CERN. The goal of AEgIS is to test the weak equivalence principle with a precision of 1% on the gravitational acceleration g by measuring the vertical position of the anni- hilation vertex of antihydrogen atoms after their free fall in a horizontal vacuum pipe. With the emulsion technology developed at the University of Bern we propose to improve the performance of AEgIS by exploiting the superior position resolution of emulsion films over other particle de- tectors. The idea is to use a new type of emulsion films, especially developed for applications in vacuum, to yield a spatial resolution of the order of one micron in the measurement of the sag of the antihydrogen atoms in the gravitational field. This is an order of magnitude better than what was planned in the original AEgIS proposal.

description: Multi-Object Tracking (MOT) is one of the most fundamental computer vision tasks that contributes to various video analysis applications. Despite the recent promising progress, current MOT research is still limited to a fixed sampling frame rate of the input stream. In fact, we empirically found that the accuracy of all recent state-of-the-art trackers drops dramatically when the input frame rate changes. For a more intelligent tracking solution, we shift the attention of our research work to the problem of Frame Rate Agnostic MOT (FraMOT), which takes frame rate insensitivity into consideration. In this paper, we propose a Frame Rate Agnostic MOT framework with a Periodic training Scheme (FAPS) to tackle the FraMOT problem for the first time. Specifically, we propose a Frame Rate Agnostic Association Module (FAAM) that infers and encodes the frame rate information to aid identity matching across multi-frame-rate inputs, improving the capability of the learned model in handling complex motion-appearance relations in FraMOT. Moreover, the association gap between training and inference is enlarged in FraMOT because those post-processing steps not included in training make a larger difference in lower frame rate scenarios. To address it, we propose Periodic Training Scheme (PTS) to reflect all post-processing steps in training via tracking pattern matching and fusion. Along with the proposed approaches, we make the first attempt to establish an evaluation method for this new task of FraMOT in two different modes, i.e., known frame rate and unknown frame rate, aiming to handle a more complex situation. The quantitative experiments on the challenging MOT17/20 dataset (FraMOT version) have clearly demonstrated that the proposed approaches can handle different frame rates better and thus improve the robustness against complicated scenarios.

On the structure of even $K$-groups of rings of algebraic integers

Subjects: subject: Number Theory (math.NT)
subject: FOS: Mathematics

description: In this paper, we describe the higher even $K$-groups of the ring of integers of a number field in terms of class groups of an appropriate extension of the number field in question. This is a natural extension of the previous collective works of Browkin, Keune and Kolster, where they considered the case of $K_2$. We then revisit the Kummer's criterion of totally real fields as generalized by Greenberg and Kida. In particular, we give an algebraic $K$-theoretical formulation of this criterion which we will prove using the algebraic $K$-theoretical results developed here.

description: We propose a new model of slow-roll inflation in string cosmology, based on warped throat supergravity solutions displaying `walking' dynamics, i.e. the coupling constant of the dual gauge theory slowly varies over a range of energy scales. The features of the throat geometry are sourced by a rich field content, given by the dilaton and RR and NS fluxes. By considering the motion of a D3-brane probe in this geometry, we are able to analytically calculate the brane potential in a physically interesting regime. This potential has an inflection point: in its proximity we realize a model of inflation lasting sixty e-foldings, and whose robust predictions are in agreement with current observations. We are also able to interpret some of the most interesting aspects of this scenario in terms of the properties of the QFT dual theory.

Local Projections

description: We study the transmission of monetary policy shocks using daily consumption, corporate sales and employment series. We find that the economy responds at both short and long lags that are variable in economically significant ways. Consumption reacts in one week, reaches a local trough in one quarter, recovers, and declines again after three quarters. Sales follow a similar pattern, but the initial drop, while delayed (one month), is deeper. In contrast, employment falls monotonically for five quarters albeit with a smaller impact reaction. We show that these short lags are masked by time aggregation at lower —quarterly— frequencies.
Effective material parameter retrieval for thin sheets: theory and application to graphene, thin silver films, and single-layer metamaterials

description: An important tool in the field of metamaterials is the extraction of effective material parameters from simulated or measured scattering parameters of a sample. Here we discuss a retrieval method for thin-film structures that can be approximated by a two-dimensional scattering sheet. We determine the effective sheet conductivity from the scattering parameters and we point out the importance of the magnetic sheet current to avoid an overdetermined inversion problem. Subsequently, we present two applications of the sheet retrieval method. First, we determine the effective sheet conductivity of thin silver films and we compare the resulting conductivities with the sheet conductivity of graphene. Second, we apply the method to a cut-wire metamaterial with an electric dipole resonance. The method is valid for thin-film structures such as two-dimensional metamaterials and frequency-selective surfaces and can be easily generalized for anisotropic or chiral media.

description: We construct exact solutions, which represent regular charged rotating Kaluza-Klein multi-black holes in the five-dimensional pure Einstein-Maxwell theory. Quantization conditions between the mass, the angular momentum, and charges appear from the regularity condition of horizon. We also obtain multi-black string solutions by taking some limits in the solutions. We extend the black hole solutions to the five-dimensional Einstein-Maxwell-Chern-Simons theory with an arbitrary Chern-Simons coupling constant.

description: Recent studies have utilized sparse classifications to predict categorical variables from high-dimensional brain activity signals to expose human's intentions and mental states, selecting the relevant features automatically in the model training process. However, existing sparse classification models will likely be prone to the performance degradation which is caused by noise inherent in the brain recordings. To address this issue, we aim to propose a new robust and sparse classification algorithm in this study. To this end, we introduce the correntropy learning framework into the automatic relevance determination based sparse classification model, proposing a new correntropy-based robust sparse logistic regression algorithm. To demonstrate the superior brain activity decoding performance of the proposed algorithm, we evaluate it on a synthetic dataset, an electroencephalogram (EEG) dataset, and a functional magnetic resonance imaging (fMRI) dataset. The extensive experimental results confirm that not only the proposed method can achieve higher classification accuracy in a noisy and high-dimensional classification task, but also it would select those more informative features for the decoding scenarios. Integrating the correntropy learning approach with the automatic relevance determination technique will significantly improve the robustness with respect to the noise, leading to more adequate robust sparse brain decoding algorithm. It provides a more powerful approach in the real-world brain activity decoding and the brain-computer interfaces.
Competency and performance measures for organizations in the construction industry

Organizations operating in the construction industry seek to understand how to successfully identify and manage competencies, given the significant influence they have on performance. Thus, organizations need to explore new approaches for assessing and enhancing their competencies to improve their performance. This paper presents a review of past studies and identifies the most common organizational competency and performance measures. A focus group was conducted to evaluate and verify the list of identified competency and performance measures. The contributions of this paper are threefold. First, this paper addresses the lack of studies on organizational-level competencies specifically for the construction domain. Second, this paper identifies, categorizes, and ranks organizational competency and performance measures. Third, the categorization of competency and performance measures, verified by the focus group, provides organizations with a systematic method to evaluate their competencies and improve their performance.

description: We review recent progress in the electronic structure study of intrinsic magnetic topological insulators (MnBi$_2$Te$_4$)(Bi$_2$Te$_3$)$_n$ ($n=0,1,2,3$) family. Specifically, we focus on the ubiquitously (nearly) gapless behavior of the topological surface state Dirac cone observed by photoemission spectroscopy, even though a large Dirac gap is expected because of surface ferromagnetic order. The dichotomy between experiment and theory concerning this gap behavior is perhaps the most critical and puzzling question in this frontier. We discuss various proposals accounting for the lack of magnetic effect on the topological surface state Dirac cone, which are mainly categorized into two pictures, magnetic reconfiguration, and topological surface state redistribution. Band engineering towards opening a magnetic gap of topological surface states provides great opportunities to realize quantized topological transport and axion electrodynamics at higher temperatures.
