description: We calculate the spectrum of large angle cosmic microwave background (CMB) anisotropies due to quantum fluctuations of the gravitational wave modes in one-bubble open inflation models. We find the bubble-wall fluctuation modes, which had been thought to exist discretely in previous analyses, are actually contained in the continuous spectrum of gravitational wave modes when the gravitational coupling is correctly taken into account. Then we find that the spectrum of the tensor CMB anisotropy can be decomposed into the part due to the wall fluctuation modes and that due to the usual gravitational wave modes in a way which is almost model-independent, even when the gravitational coupling is strong. We also discuss observational constraints on the model parameters. We find that an appreciable portion of the parameter space is excluded but the remaining allowable region is still wide enough to leave the one-bubble scenario viable.

description: The issue of testing CPT invariance at a $B$ factory is considered. We present asymmetries that permit a clean extraction of quantities parametrizing direct and indirect CPT violation, using information from $Υ(4S)$ decay via coherent $B_d\overline{B_d}$ pairs into various final states. Estimates are given of the bounds on CPT violation that could be obtained in present and planned machines.

Rizóbios

description: O nitrogênio é um nutriente que propicia efeitos benéficos na produtividade, na qualidade química e fisiológica das sementes de feijão, sendo que este não pode ser incorporado diretamente aos organismos eucariotos, podendo ser assimilado, principalmente, graças à ação de micro-organismos que possuem a capacidade de realizar a Fixação Biológica de Nitrogênio (FBN). O grupo de bactérias chamado de rizóbios têm alta capacidade de realizar a FBN quando em simbiose com plantas leguminosas, entre elas o Vigna unguiculata (L.) Walp. (feijão caupi). O objetivo do trabalho foi analisar a produtividade de V. unguiculata (L.) Walp. inoculado com Rhizobium tropici para uso na agricultura familiar, de forma a utilizar o cultivo em simbiose como alternativa sustentável de produção agrícola para a região, buscando um melhor aproveitamento do solo e da área cultivável. O delineamento estatístico foi o de inteiramente casualizado com 4 tratamentos e quatro repetições. Cada parcela totalizou uma área de 6 m2 – 3m x 2m. O inoculante utilizado foi da estirpe BR322/520/534 de Rhizobium tropici e a variedade de feijão caupi utilizada foi a BR3-Tracuateua purificada. Os tratamentos utilizados foram: T1 - Sem PK e sem inoculação (Controle); T2 - Com PK e sem inoculação; T3 - Com PK e Com inoculação e; T4 - Sem PK e com inoculação. As variáveis analisadas foram: Número de Vagens (NV), Massa Seca das Vagens (MSV) e Massa Seca da Parte Aérea (MSPA). Evidenciou-se a eficiência da inoculação em todos os tratamentos analisados, considerando todas as variáveis analisadas, propiciando maior produtividade de grãos, sendo esta estatisticamente igual com ou sem uso de adubação com PK, obtendo aumento, em relação à testemunha, de 122,27% no tratamento T4 (com inoculação e sem adubação).

description: It has been shown that injecting noise into the neural network weights during the training process leads to a better generalization of the resulting model. Noise injection in the distributed setup is a straightforward technique and it represents a promising approach to improve the locally trained models. We investigate the effects of noise injection into the neural networks during a decentralized training process. We show both theoretically and empirically that noise injection has no positive effect in expectation on linear models, though. However for non-linear neural networks we empirically show that noise injection substantially improves model quality helping to reach a generalization ability of a local model close to the serial baseline.

description: Earth system models suffer from various structural and parametric errors in their representation of nonlinear, multi-scale processes, leading to uncertainties in their long-term projections. The effects of many of these errors (particularly those due to fast physics) can be quantified in short-term simulations, e.g., as differences between the predicted and observed states (analysis increments). With the increase in the availability of high-quality observations and simulations, learning nudging from these increments to correct model errors has become an active research area. However, most studies focus on using neural networks, which while powerful, are hard to interpret, are data-hungry, and poorly generalize out-of-distribution. Here, we show the capabilities of Model Error Discovery with Interpretability and Data Assimilation (MEDIDA), a general, data-efficient framework that uses sparsity-promoting equation-discovery techniques to learn model errors from analysis increments. Using two-layer quasi-geostrophic turbulence as the test case, MEDIDA is shown to successfully discover various linear and nonlinear structural/parametric errors when full observations are available. Discovery from spatially sparse observations is found to require highly accurate interpolation schemes. While NNs have shown success as interpolators in recent studies, here, they are found inadequate due to their inability to accurately represent small scales, a phenomenon known as spectral bias. We show that a general remedy, adding a random Fourier feature layer to the NN, resolves this issue enabling MEDIDA to successfully discover model errors from sparse observations. These promising results suggest that with further development, MEDIDA could be scaled up to models of the Earth system and real observations.

description: The increasing availability of hydrological and physiographic spatiotemporal data has boosted machine learning's role in rapid flood mapping. Yet, data scarcity, especially high-resolution DEMs, challenges regions with limited access. This paper examines how DEM type and resolution affect flood prediction accuracy, utilizing a cutting-edge deep learning (DL) method called 1D convolutional neural network (CNN). It utilizes synthetic hydrographs as training input and water depth data obtained from LISFLOOD-FP, a 2D hydrodynamic model, as target data. This study investigates digital surface models (DSMs) and digital terrain models (DTMs) derived from a 1 m LIDAR-based DTM, with resolutions from 15 to 30 m. The methodology is applied and assessed in an established benchmark, the city of Carlisle, UK. The models' performance is then evaluated and compared against an observed flood event using RMSE, Bias, and Fit indices. Leveraging the insights gained from this region, the paper discusses the applicability of the methodology to address the challenges encountered in a data-scarce flood-prone region, exemplified by Pakistan. Results indicated that utilizing a 30 m DTM outperformed a 30 m DSM in terms of flood depth prediction accuracy by about 21% during the flood peak stage, highlighting the superior performance of DTM at lower resolutions. Increasing the resolution of DTM to 15 m resulted in a minimum 50% increase in RMSE and a 20% increase in fit index across all flood stages. The findings emphasize that while a coarser resolution DEM may impact the accuracy of machine learning models, it remains a viable option for rapid flood prediction. However, even a slight improvement in data resolution in data-scarce regions would provide significant added value, ultimately enhancing flood risk management.

description: The amount of textual data has reached a new scale and continues to grow at an unprecedented rate. IBM's SystemT software is a powerful text analytics system, which offers a query-based interface to reveal the valuable information that lies within these mounds of data. However, traditional server architectures are not capable of analyzing the so-called "Big Data" in an efficient way, despite the high memory bandwidth that is available. We show that by using a streaming hardware accelerator implemented in reconfigurable logic, the throughput rates of the SystemT's information extraction queries can be improved by an order of magnitude. We present how such a system can be deployed by extending SystemT's existing compilation flow and by using a multi-threaded communication interface that can efficiently use the bandwidth of the accelerator.

description: In this work, we perform real time simulations for probing the non-Abelian fusion of a pair of Majorana zero modes (MZMs). The nontrivial fusion outcomes can be either a vacuum, or an unpaired fermion, which reflect the underlying non-Abelian statistics. The two possible outcomes can cause different charge variations in the nearby probing quantum dot (QD), while the charge occupation in the dot is detected by a quantum point contact. In particular, we find that gradual fusion and gradual coupling of the MZMs to the QD (in nearly adiabatic switching-on limit) provide a simpler detection scheme than sudden coupling after fusion to infer the coexistence of two fusion outcomes, by measuring the occupation probability of the QD. For the scheme of sudden coupling (after fusion), we propose and analyze continuous weak measurement for the quantum oscillations of the QD occupancy. From the power spectrum of the measurement currents, one can identify the characteristic frequencies and infer thus the coexistence of the fusion outcomes.

description: We show that smooth domain wall spacetimes supported by a scalar field separating two anti-de-Sitter like regions admit a single graviton bound state. Our analysis yields a fully non-linear supergravity treatment of the Randall-Sundrum model. Our solutions describe a pp-wave propagating in the domain wall background spacetime. If the latter is BPS, our solutions retain some supersymmetry. Nevertheless, the Kaluza-Klein modes generate ``pp curvature'' singularities in the bulk located where the horizon of AdS would ordinarily be.

description: In these proceedings we discuss the family of Vector Boson Scattering (VBS) processes, in particular we look at a very recent result from the CMS collaboration where a search was performed for VBS in the four-lepton and two-jet final state using proton-proton collisions at 13 TeV. The electroweak production of two Z bosons in association with two jets was measured with an observed (expected) significance of 2.7 (1.6) standard deviations, using a multivariate classifier. Additionally an expected significance of 1.2 standard deviations was found using matrix elements techniques. In this work we discuss the latter approach in detail.

description: We investigate the effect of heavy flavor contributions to vector boson ($V$ = $γ$, $Z$, $W$) production which is described by the Drell-Yan mechanism. All reactions with bottom and top quarks ($Q_i$ = $b$, $t$) in the final state, like $q_1 + \bar{q}_2\rightarrow V + Q_1 + \bar{Q}_2$ and $g + g\rightarrow V + Q_1 + \bar{Q}_2$, are considered. This study also includes the virtual contributions containing heavy flavor loops which were not taken into account earlier in the literature. Our analysis reveals that the above corrections to the Drell-Yan cross section are very small. Only at energies characteristic for the LHC they are of the same order of magnitude as the order \alphastwo~QCD contributions due to light quark and gluon subprocesses calculated earlier in the literature.

description: We have studied a problem of the tachyon mediated D-brane - D-brane annihilation from the underlying world-volume gauge field theory point of view. The initial state was chosen in the form of two D-branes crossing at a non-zero angle, which is non-supersymmetric configuration generically. This state was not a groundstate of the theory and the problem at hand was a model, where we had rather precise control over the behavior of the theory.Some applications of this model to the D-brane physics and conclusions about stability of several configurations were made. By taking a T-dual picture of this process on a T^2 torus, we derived known conclusion about the instability of a system consisting of D-0 and D-2 branes, and found its decay modes.

description: The main objective of this deliverable is to describe the final status of the 5G EVE facility in terms of architecture, capabilities, network KPIs, and infrastructures.
 This document presents the main features and the related improvements that the 5G EVE facility has recorded during this year (2021). Indeed, whereas with Milestone 8 (MS8), which was reached at the end of 2019, the project provided all the components needed for building the E2E infrastructure, MS9 was achieved in June 2020, followed by MS10 in December, with the integration of these components into the infrastructure. In this way, the project realized the final validation of the E2E facility, for Milestone 11 (MS11), consisting of an E2E network framework based on 5G Stand Alone (SA) mode with R15 capabilities in either FR1 or FR2 frequency bands. The complete infrastructure is summarized in this deliverable, showing that 5G EVE is in advance in terms of features availabilities compared to the current commercial deployments implemented in Europe. At the end of the project activities 5G EVE is then able to propose to the verticals, that used 5G EVE facility, an E2E framework allowing them to test and validate their use-cases, even anticipating their commercial 5G operation.
 More in details, the aim of this deliverable is to describe the main activities that have been carried out to achieve the challenging objective of building and delivering the 5G EVE Pan-European E2E facility. First, the document explains the main architecture design that is adopted for implementing this 5G platform as a support for the verticals experimenting their use-cases, showing the 5G EVE facility potential to deploy services considering also multi-sites framework. Next, the network infrastructure KPIs and the methodology that has been put in place for measuring, collecting, and monitoring them by the vertical partners is described in details. Then, before going through the description of each site facility, a synthesis table of the main features supported by the 5G EVE facility is provided. Last, this deliverable is completed by presenting the final version of the 5G EVE facility in every site in Italy, France, Spain and Greece.

description: A series of novel D–π–A star-shaped molecules with triphenylamine (TPA) fragments as cores, diketopyrrolopyrrole (DPP) fragments as arms, and different conjugate π-bridges those connect TPA and DPP fragments have been designed for small molecules based organic solar cells (OSCs) applications. The optical, electronic, and charge transporting properties have been systematically investigated by means of density functional theory (DFT) and time-dependent DFT (TD-DFT) methods. The parameters such as energetic driving force ΔEL-L, adiabatic ionisation potentials (AIP), and adiabatic electron affinities (AEA) were also calculated at the same level to preliminarily evaluate the performance of the OSCs. The results of frontier molecular orbitals (FMOs) show that the designed molecules provide the best match matched energy levels with typical acceptors PCBM, bisPCBM, and PC70BM except for molecule containing benzo[c][1,2,5]thiadiazole unit because of its low energetic driving force ΔEL-L. It turned out that the FMO energy levels, the band gaps, AIP, AEA, and absorption spectrum can be tuned effectively by the introduction of different groups. Additionally, our results suggest that the designed molecules can act as promising candidates for donor materials and ambipolar charge transport materials for OSCs.
Multiwavelength Properties of Blazars
Creators: name: Urry, C. Megan
Publisher: name: arXiv
Year: 1997
Subjects: subject: Astrophysics (astro-ph)

description: The multiwavelength spectra of blazars appear to be dominated by nonthermal emission from a relativistic jet oriented close to the line of sight. The recent detection of many blazars at gamma-ray energies strongly supports this scenario. High quality multiwavelength monitoring data for the brightest one or two blazars suggest the optical through X-ray continuum is synchrotron emission from an inhomogeneous jet. The gamma-rays are likely due to Compton scattering of lower energy photons, either from within the jet or from the surrounding gas. The physical properties of the jet and the way in which it is produced are still largely a mystery but are probably related in some way to accretion onto a central supermassive black hole. There is little direct observational evidence for accretion disks in blazars, although there is evidence for winds which might emanate from disks.

description: This research study explores the applicability of Deep Reinforcement Learning (DRL) for thermal control based on Computational Fluid Dynamics. To accomplish that, the forced convection on a hot plate prone to a pulsating cooling jet with variable velocity has been investigated. We begin with evaluating the efficiency and viability of a vanilla Deep Q-Network (DQN) method for thermal control. Subsequently, a comprehensive comparison between different variants of DRL is conducted. Soft Double and Duel DQN achieved better thermal control performance among all the variants due to their efficient learning and action prioritization capabilities. Results demonstrate that the soft Double DQN outperforms the hard Double DQN. Moreover, soft Double and Duel can maintain the temperature in the desired threshold for more than 98% of the control cycle. These findings demonstrate the promising potential of DRL in effectively addressing thermal control systems.

description: In recent years, significant progress has been made in imaging techniques. Osteoarticular ultrasound is becoming more and more common practice. The main ultrasound features of gout have been defined. Its potential in the diagnosis and monitoring of gout has been well demonstrated. The recent inclusion of osteoarticular ultrasound in the new ACR / EULAR 2015 classification of gout, without a doubt, means that this imaging technique is a valid tool in the diagnosis of gout. The dual energy scanner (DECT) is also included in the 2015 ACR / EULAR criteria for gout. Its use remains limited in practice because of its low sensitivity.

description: The formulation of the real and virtual photon production rate from strongly interacting matter is presented in the framework of finite temperature field theory. The changes in the hadronic spectral function induced by temperature are discussed within the ambit of the Walecka type model, gauged linear and non-linear sigma models, hidden local symmetry approach and QCD sum rule approach. Possibility of observing the direct thermal photon and lepton pair from quark gluon plasma has been contrasted with those from hot hadronic matter with and without medium effects for various mass variation scenarios. At SPS energies, in-medium effects of different magnitude on the hadronic properties for the Walecka model, Brown-Rho scaling and Nambu scaling scenarios are conspicuously visible through the low invariant mass distribution of dilepton and transverse momentum spectra of photon. However, at RHIC energies the thermal photon (dilepton) spectra originating from Quark Gluon Plasma overshines those from hadronic matter for large transverse momentum (invariant mass) irrespective of the models used for evaluating the finite temperature effects on the hadronic properties. It is thus expected that both at RHIC and LHC energies the formation of Quark Gluon Plasma in the initial stages may indeed turn out to be a realistic scenario.

- Les exemplaires [[worker]] rapportes par M. Alluaud de Diego-Suarez et de Nossi-Be different d'un type de Morondava queje tiens de l'auteur, par la sculpture plus forte, plus rugueuse et les epines du metanotum plus epaisses et plus divergentes. Du reste ils different notablement entre eux a cet egard, c'est pourquoi je ne crois pas devoir nommer cette variete apparemment inconstante.

description: Rapid dissolution and transfer of samples are crucial steps in hyperpolarization methods such as dissolution dynamic nuclear polarization (dDNP) and quantum-rotor-induced polarization (QRIP). Here we introduce a simple and modular dissolution transfer device, and we demonstrate its application for QRIP. This device operates with low pressures and solvent volumes compared to state-of-the-art dDNP setups. On the other hand, transfer times are longer, although sufficient for 13C NMR spectroscopy. Our approach does not require an additional cryostat.

description: Four new integrable evolutions equations with operator Lax pairs are found for an octonion variable. The method uses a scaling ansatz to set up a general polynomial form for the evolution equation and the Lax pair, using KdV and mKdV scaling weights. A condition for linear differential operators to be a Lax pair over octonions is formulated and solved for the unknown coefficients in the polynomials.

description: Establishing a human colony on Mars is one of the most ambitious endeavors of our time. This paper provides a comprehensive assessment of the challenges and solutions related to Mars colonization, emphasizing sustainability, efficiency, and the well-being of colonists. We begin by analyzing the Martian environment, focusing on challenges such as radiation, dust storms, temperature variations, and low atmospheric pressure. The discourse then transitions into technological solutions, exploring innovations in infrastructure, energy production, transportation, and life support systems. Special attention is paid to harnessing in-situ resources and recent advancements like Martian concrete, aeroponics, and algae bioreactors. The human dimension is addressed, from the psychological implications of prolonged isolation to physiological considerations in reduced gravity. Economic considerations encapsulate the cost-benefit analysis of in-situ resource utilization versus Earth transport and the potential incentives for private sector investment. The paper culminates in recommendations for future research, highlighting areas pivotal for refining the blueprint of Mars colonization. This work serves as a foundational guide for researchers, policymakers, and visionaries aiming to make humanity's interplanetary future a reality.

description: Hydrazones are popular building blocks in the development of functional materials because of their simple structure, straightforward synthesis, hydrolytic stability and tunable properties. Although a significant body of experimental information has been accumulated on the hydrazone-based rotary switches, mechanistic studies are still scarce. The effect of different stator units (phenyl-, naphthyl- and quinolinyl) on the on/off state distribution is studied in details at various computational levels in order to select a reliable computational level for a further computational study of the switching mechanism and rotary action of these systems.

description: Angular and energy distributions for leptons and bottom quarks in the process e+e- --> t tbar --> l/b ... have been calculated assuming the most general top-quark couplings. The double distributions depend both on modification of the top-quark production and tbW decay vertices. However, the leptonic angular distribution turned out to be insensitive to non-standard parts of tbW vertex. The method of optimal observables have been used to estimate sensitivity of future measurements at linear e+e- colliders

description: The purpose of this study was to explore how learners with disability at an orphanage can learn in an inclusive setting with learners without disability and how their learning can foster sustainability towards achieving the fourth United Nations Sustainable Development Goal. This research examined inclusive educational strategies by evaluating the operation of teaching and learning through a voluntary sector education project designed to educate children in orphanage homes for children with and without disability in reading and vocational activities. In order to assess the effectiveness of the strategies, stakeholders’ views and experiences of the project were investigated. From the impact evaluation of the project and investigation of all stakeholders’ views of the project, guidelines of good pedagogical practice that can be disseminated to other projects, schools or informal educational institutions were drawn up. In addition to examining the impact of the voluntary sector education project, this research also scrutinized the National Education Policy of Nigeria, with regards to inclusive education strategies for learners with disability. These policy documents were analysed in order to identify features of the education policy which are consistent or inconsistent with SDG 4 targets for learners with disability. Data were collected through a process of triangulation using focus groups, interviews and document analysis. Themes that could help educators, administrators and policy makers understand how to develop educational programs that can achieve the fourth United Nations Sustainable Development Goal for learners with disability were drawn. The findings from this research advocates for learners with and without disability to be educated together in an inclusive setting as a way of achieving SDG 4 for learners with disability. Further research to consider how children with disability who live in remote areas can be educated on how to protect themselves during the COVID-19 pandemic and how indigenous knowledge can be used to achieve SDG 4 for children with disability in the absence of formal education was recommended.

description: As automated vehicles enter public roads, safety in a near-infinite number of driving scenarios becomes one of the major concerns for the widespread adoption of fully autonomous driving. The ability to detect anomalous situations outside of the operational design domain is a key component in self-driving cars, enabling us to mitigate the impact of abnormal ego behaviors and to realize trustworthy driving systems. On-road anomaly detection in egocentric videos remains a challenging problem due to the difficulties introduced by complex and interactive scenarios. We conduct a holistic analysis of common on-road anomaly patterns, from which we propose three unsupervised anomaly detection experts: a scene expert that focuses on frame-level appearances to detect abnormal scenes and unexpected scene motions; an interaction expert that models normal relative motions between two road participants and raises alarms whenever anomalous interactions emerge; and a behavior expert which monitors abnormal behaviors of individual objects by future trajectory prediction. To combine the strengths of all the modules, we propose an expert ensemble (Xen) using a Kalman filter, in which the final anomaly score is absorbed as one of the states and the observations are generated by the experts. Our experiments employ a novel evaluation protocol for realistic model performance, demonstrate superior anomaly detection performance than previous methods, and show that our framework has potential in classifying anomaly types using unsupervised learning on a large-scale on-road anomaly dataset.

description: Multi-step stock index forecasting is vital in finance for informed decision-making. Current forecasting methods on this task frequently produce unsatisfactory results due to the inherent data randomness and instability, thereby underscoring the demand for advanced forecasting models. Given the superiority of capsule network (CapsNet) over CNN in various forecasting and classification tasks, this study investigates the potential of integrating a 1D CapsNet with an LSTM network for multi-step stock index forecasting. To this end, a hybrid 1D-CapsNet-LSTM model is introduced, which utilizes a 1D CapsNet to generate high-level capsules from sequential data and a LSTM network to capture temporal dependencies. To maintain stochastic dependencies over different forecasting horizons, a multi-input multi-output (MIMO) strategy is employed. The model's performance is evaluated on real-world stock market indices, including S&P 500, DJIA, IXIC, and NYSE, and compared to baseline models, including LSTM, RNN, and CNN-LSTM, using metrics such as RMSE, MAE, MAPE, and TIC. The proposed 1D-CapsNet-LSTM model consistently outperforms baseline models in two key aspects. It exhibits significant reductions in forecasting errors compared to baseline models. Furthermore, it displays a slower rate of error increase with lengthening forecast horizons, indicating increased robustness for multi-step forecasting tasks.

- [[worker]]. Differe du type de l'espece, par la taille un peu plus faible (4 - 8 mill.) et surtout par la forme du metanotum dont la face basale est bien plus fortement creusee en selle (voir la figure). Couleur comme chez le type. Chez les [[worker]] moyennes et grandes, le pronotum et le mesonotum sont ordinairement plus ou moins ferrugineux; chez les tres grands exemplaires, les taches de l'abdomen sont parfois petites et presque effacees.

description: We compute the quark-monopole potential for ${\cal N}=4$ super Yang-Mills in the large $N$ limit. We find an attractive potential that falls off as 1/L and is manifestly invariant under $g\to 1/g$. The strength of the potential is less than the quark-antiquark and monopole-antimonopole potentials.

description: We present the first determination of the near-infrared K-band luminosity function of field galaxies from a wide field K-selected redshift survey. The best fit Schechter function parameters are $M^* = -23.12 +5log(h)$, $α= -0.91$, and $ϕ^* = 1.66 \times 10^{-2} h^3 ~ Mpc^{-3}$. We estimate that systematics are no more than 0.1 mag in $M^*$ and 0.1 in $α$, which is comparable to the statistical errors on this measurement.
