description: This paper investigated the potential of a multivariate Transformer model to forecast the temporal trajectory of the Fraction of Absorbed Photosynthetically Active Radiation (FAPAR) for short (1 month) and long horizon (more than 1 month) periods at the regional level in Europe and North Africa. The input data covers the period from 2002 to 2022 and includes remote sensing and weather data for modelling FAPAR predictions. The model was evaluated using a leave one year out cross-validation and compared with the climatological benchmark. Results show that the transformer model outperforms the benchmark model for one month forecasting horizon, after which the climatological benchmark is better. The RMSE values of the transformer model ranged from 0.02 to 0.04 FAPAR units for the first 2 months of predictions. Overall, the tested Transformer model is a valid method for FAPAR forecasting, especially when combined with weather data and used for short-term predictions.

description: Arguments are made in favor of broadening the scope of the various approaches to splitting spacetime into a single common framework in which measured quantities, derivative operations, and adapted coordinate systems are clearly understood in terms of associated test observer families. This ``relativity of splitting formalisms" for fully nonlinear gravitational theory has been tagged with the name "gravitoelectromagnetism" because of the well known analogy between its linearization and electromagnetism, and it allows relationships between the various approaches to be better understood and makes it easier to extrapolate familiarity with one approach to the others. This is important since particular problems or particular features of those problems in gravitational theory are better suited to different approaches, and the present barriers between the proponents of each individual approach sometimes prevent the best match from occurring.

description: We propose a new non-perturbative method for studying UV complete unitary quantum field theories (QFTs) with a mass gap in general number of spacetime dimensions. The method relies on unitarity formulated as positive semi-definiteness of the matrix of inner products between asymptotic states (in and out) and states created by the action of local operators on the vacuum. The corresponding matrix elements involve scattering amplitudes, form factors and spectral densities of local operators. We test this method in two-dimensional QFTs by setting up a linear optimization problem that gives a lower bound on the central charge of the UV CFT associated to a QFT with a given mass spectrum of stable particles (and couplings between them). Some of our numerical bounds are saturated by known form factors in integrable theories like the sine-Gordon, E8 and O(N) models.

Planetesimal disk evolution driven by planetesimal-planetesimal gravitational scattering
Creators: name: Rafikov, Roman R.
Publisher: name: arXiv
Year: 2002
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We investigate the process of an inhomogeneous planetesimal disk evolution caused by the planetesimal-planetesimal gravitational scattering. We develop a rather general approach based on the kinetic theory which self-consistently describes the evolution in time and space of both the disk surface density and its kinematic properties -- dispersions of eccentricity and inclination. The gravitational scattering of planetesimals is assumed to be in the dispersion-dominated regime which considerably simplifies analytical treatment. The resultant equations are of advection-diffusion type. Distance dependent scattering coefficients entering these equations are calculated analytically under the assumption of two-body scattering in the leading order in Coulomb logarithm. They are essentially nonlocal in nature. Our approach allows one to explore the dynamics of nonuniform planetesimal disks with arbitrary mass and random velocity distributions. It can also naturally include other physical mechanisms which are important for the evolution of such disks -- gas drag, migration, and so on.

description: We report in this paper spectroscopic and photometric analysis of eight massive stars observed during Campaign 8 of the Kepler/K2 mission from January to March 2016. Spectroscopic data were obtained on these stars at OPD/LNA, Brazil, and their stellar parameters determined using SME. Periodic analyses of the light curves were performed through CLEANEST and PERIOD04 algorithms. Mass, luminosity, and radius of our stars were estimated employing CESAM+POSC grids. Three of our stars show significant periodicity. K2 ID 220679442 and K2 ID 220532854 have periods linked to the stellar rotation. K2 ID 220532854 has prominent silicon lines (Si II 4128-4131), a characteristic presented in the peculiar class of Ap magnetic main sequence stars. However, in our spectral analysis, this object was found to be an evolved, luminous giant star. K2 ID 220466722 was revealed to be a $δ$ Scuti variable, and 40 individual frequencies were determined for this star. No significant periodicity was found in the light curves for the remaining stars analyzed in this work, besides the instrumental one.

description: This paper reports on the availability, collection and transportation costs of agricultural crop residue for cellulosic ethanol processing in the state of Washington using Geographic Information Systems. The GIS Network Analyst extension toolset is employed to map and spatially analyze the crop residue available within given distances/haul zones for 12 eastern counties. Using census feature classification codes, driving speed limits were assigned to all road segments to calculate haul times to a specific biorefinery location. The feedstock farm gate cost, transportation costs, resource availability and geographic distribution were incorporated to derive feedstock supply curves. To better understand how variation in transportation costs affects the feedstock delivered costs, a sensitivity analysis is conducted incorporating a range of diesel prices.

description: We present a stability analysis of the two-dimensional t-t' Hubbard model for various values of the next-nearest-neighbor hopping t', and electron concentrations close to the Van Hove filling by means of the flow equation method. For t' > -t/3 a d_{x^2-y^2}-wave Pomeranchuk instability dominates (apart from antiferromagnetism at small t'). At t' < -t/3 the leading instabilities are a g-wave Pomeranchuk instability and p-wave particle-hole instability in the triplet channel at temperatures T < 0.15t, and an s^*-magnetic phase for T > 0.15t; upon increasing the electron concentration the triplet analog of the flux phase occurs at low temperatures. Other weaker instabilities are found also.

description: For efficient photovoltaic conversion, it is important to understand how quantum entropy-related quantities evolve during the photovoltaic process. In this study, using a double quantum dot (DQD) photocell model, we explored the dynamic quantum entropy-related parameters during the photovoltaic output. The findings demonstrate that the dynamic photovoltaic performance is compatible with quantum entropy-related parameters with varying tunneling coupling strengths, but at varied ambient temperatures, an opposing relationship is discovered between them. Hence, some thermodynamic criteria may be used to evaluate the photovoltaic process in this proposed photocell model. This work's merits include expanding our understanding of photoelectric conversion from a thermodynamic perspective as well as perhaps suggesting a new thermodynamic approach to efficient photoelectric conversion for DQD photocells.

description: Ethanol production booms in the Midwest in 2007. Regulations require ethanol be included as a fuel additive in many areas as of 2006, though consumer willingness to adopt ethanol blends voluntarily is uncertain and benchmark ethanol and oil prices fluctuate. In this context, we jointly simulate consumer demand for ethanol and ethanol transportation costs. Results demonstrate a non-linear relationship between benchmark prices and transportation costs that depends critically on (1) the prevalence of additive ethanol use in a state and (2) the proximity of local prices to parity in energy equivalent terms.

description: We report on a study of the effect upon electrical transport of spinwave scattering from charged quasiparticles in nu=1 quantum Hall ferromagnets (QHFs), including both Heisenberg (single layer) and easy-plane (bilayer) cases. We derive a quantum Langevin equation to describe the resulting diffusive motion of the charged particle and use this to calculate the contribution to low temperature conductivity from a density of charged particles. This conductivity has a power law dependence upon temperature. The contribution is small at low temperatures increasing to a large value at relatively modest temperatures. We comment upon high temperature transport and upon the contribution of scattering to the width of the zero bias peak in inter-layer tunneling conductance.

In this paper we continue developing the SoV program for higher-rank spin chains and demonstrate how to derive the measure for the su(3) case. Our results are a natural consequence of factorisability of the wave function and functional orthogonality relations following from the interplay between Baxter equations for Q-functions and their dual.

description: This study re-examines the perceived importance of 36 carrier selection variables to both motor carriers and shippers. The ranking discrepancies identified indicate that shippers and carriers classify most, but not all motor carrier selection variables similarly. Fortunately, motor carrier perceptions have improved since the original 2007 study. To enhance shipper satisfaction, carriers must emphasize the more important selection variables. Carriers now realize the importance of providing information and services through a comprehensive, Web-enhanced electronic data interchange (EDI). Currently carriers need to key on offering more flexible rates and respond effectively to emergency or unexpected situations.

description: The Minneapolis Upper Harbor is almost 1800 miles upriver from the Gulf of Mexico. To go the last 20 miles from St Paul to the head of navigation at the Minneapolis Upper Harbor, tows are limited to two barges and have to go through 3 small locks to pass the St Anthony Falls. In contrast, below St Paul tows consist of 15 barges and the distances between the 26 large locks on the Upper Mississippi River average over 35 miles. The Upper Harbor has a small number of private shippers but the largest land parcel is the 42 acres that contains the public barge terminal (Upper Harbor Terminal) owned by the City of Minneapolis. A number of proposals contemplate closing the Minneapolis Upper Harbor so that the Mississippi River Corridor area above the St. Anthony Fall Locks and Dams can be converted to housing, light industry, and recreational uses, which proponents consider the “highest and best use” for prime waterfront land. Depending on the ultimate mix land of uses, it is assumed that tax revenues and economic activity will dramatically increase. These proposals generally assume that that the barge traffic of relatively low value freight (such as cement, aggregate, construction materials and scrap) is of little economic consequence and can be relocated at little cost to the community. However, this study demonstrates that displacing many of these movements will cause monetary and environmental costs that previously had not been studied or quantified. There would still be a need to move materials such as sand and gravel, cement, steel products, and other construction materials into Minneapolis; and scrap metals from Minneapolis. Truck movements of grain, fertilizer and other commodities from and to northwest of Minneapolis would need to be rerouted to downstream harbors. This study estimates the monetary and public externality costs imposed by the 'modal shift', from barge to truck, that would occur if barge traffic to and from above the St. Anthony Dams was eliminated. These include haulage costs, differences in fuel consumption, changes in air emissions, highway congestion impacts, highway accident impacts, and changes in highway maintenance requirements. Coefficients from the FHWA Highway Cost Allocation Study (HCAS) are used to monetize the estimated public costs. Results from the "most likely" scenario indicate an addition of 66,000 truckloads traveling 1.2 million miles in the metro area each year. Increases in transport costs to shippers or customers exceed $4 million annually, while public cost increases, estimated with the HCAS coefficients, exceed $1 million annually

description: In nonperturbative regimes, the superfluid instability in the two-dimensional Hubbard model can be described by an emergent BCS theory with small effective pairing constants. We compute the effective couplings using a controlled bold-line diagrammatic Monte Carlo approach, which stochastically sums all skeleton Feynman diagrams dressed in the one- and two-particle channels to high expansion orders, and map out the resulting superfluid ground-state phase diagram in a range of next-nearest-neighbor hopping $0 \leq t^{\prime} \leq 0.3t$, interaction strength $0 \leq U \leq 3t$, and lattice filling $0 \leq n \leq 2$. The phase diagram is dramatically transformed in the hole-doped region and becomes particularly rich at larger doping and $t'$. At $t'=0.3$, the weak-coupling picture with the dominant triplet pairing sharply peaked at $n \approx 0.73$ due to the Van Hove singularity is replaced by a plateau of the singlet $d_{x^2-y^2}$ paring, while for $U \gtrsim 3t$ the effective couplings are consistent with the $d_{x^2-y^2}$ high-temperature superconductivity in the hole-doped region near cuprates' optimal doping.

With ANT as theoretical basis, this paper analyzed formation of family farms in the joint action of endogenous and exogenous forces. Besides, it analyzed Fengsheng Tobacco Family Farm of Guyue Town in Zhucheng City of Shandong Province and Li Chunfeng’s Family Farm in Songjiang District of Shanghai. Research indicates that different regional environments bring about different actors and also different formation paths for family farms.

description: Remaining competitive in future conflicts with technologically-advanced competitors requires us to accelerate our research and development in artificial intelligence (AI) for wargaming. More importantly, leveraging machine learning for intelligent combat behavior development will be key to one day achieving superhuman performance in this domain--elevating the quality and accelerating the speed of our decisions in future wars. Although deep reinforcement learning (RL) continues to show promising results in intelligent agent behavior development in games, it has yet to perform at or above the human level in the long-horizon, complex tasks typically found in combat modeling and simulation. Capitalizing on the proven potential of RL and recent successes of hierarchical reinforcement learning (HRL), our research is investigating and extending the use of HRL to create intelligent agents capable of performing effectively in these large and complex simulation environments. Our ultimate goal is to develop an agent capable of superhuman performance that could then serve as an AI advisor to military planners and decision-makers. This papers covers our ongoing approach and the first three of our five research areas aimed at managing the exponential growth of computations that have thus far limited the use of AI in combat simulations: (1) developing an HRL training framework and agent architecture for combat units; (2) developing a multi-model framework for agent decision-making; (3) developing dimension-invariant observation abstractions of the state space to manage the exponential growth of computations; (4) developing an intrinsic rewards engine to enable long-term planning; and (5) implementing this framework into a higher-fidelity combat simulation.

Constraining a causal dissipative cosmological model

description: In this paper a cosmological solution of polynomial type $H \approx ( t + const.)^{-1}$ for the causal thermodynamical approach of Isarel-Stewart, found in \cite{MCruz:2017, Cruz2017}, is constrained using the joint of the latest measurements of the Hubble parameter (OHD) and Type Ia Supernovae (SNIa). Since the expansion described by this solution does not present a transition from a decelerated phase to an accelerated one, both phases can be well modeled connecting both phases by requiring the continuity of the Hubble parameter at $z=z_{t}$, the accelerated-decelerated transition redshift. Our best fit constrains the main free parameters of the model to be $A_1= 1.58^{+0.08}_{-0.07}$ ($A_2=0.84^{+0.02}_{-0.02}$) for the accelerated (decelerated) phase. For both phases we obtain $q=-0.37^{+0.03}_{-0.03}$ ($0.19^{+0.03}_{-0.03}$) and $ω_{eff} = -0.58^{+0.02}_{-0.02}$ ($-0.21^{+0.02}_{-0.02}$) for the deceleration parameter and the effective equation of state, respectively. Comparing our model and LCDM statistically through the Akaike information criterion and the Bayesian information criterion we obtain that the LCDM model is preferred by the OHD+SNIa data. Finally, it is shown that the constrained parameters values satisfy the criterion for a consistent fluid description of a dissipative dark matter component, but with a high value of the speed of sound within the fluid, which is a drawback for a consistent description of the structure formation. We briefly discuss the possibilities to overcome this problem with a non-linear generalization of the causal linear thermodynamics of bulk viscosity and also with the inclusion of some form of dark energy.

Planetesimal disk evolution driven by embryo-planetesimal gravitational scattering

Publisher: name: arXiv
Year: 2002
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: The process of gravitational scattering of planetesimals by a massive protoplanetary embryo is explored theoretically. We propose a method to describe the evolution of the disk surface density, eccentricity, and inclination caused by the embryo-planetesimal interaction. It relies on the analytical treatment of the scattering in two extreme regimes of the planetesimal epicyclic velocities: shear-dominated (dynamically ``cold'') and dispersion-dominated (dynamically ``hot''). In the former, planetesimal scattering can be treated as a deterministic process. In the latter, scattering is mostly weak because of the large relative velocities of interacting bodies. This allows one to use the Fokker-Planck approximation and the two-body approximation to explore the disk evolution. We compare the results obtained by this method with the outcomes of the direct numerical integrations of planetesimal orbits and they agree quite well. In the intermediate velocity regime an approximate treatment of the disk evolution is proposed based on interpolation between the two extreme regimes. We also calculate the rate of embryo's mass growth in an inhomogeneous planetesimal disk and demonstrate that it is in agreement with both the simulations and earlier calculations. Finally we discuss the question of the direction of the embryo-planetesimal interaction in the dispersion-dominated regime and demonstrate that it is repulsive. This means that the embryo always forms a gap in the disk around it, which is in contrast with the results of other authors. The machinery developed here will be applied to realistic protoplanetary systems in future papers.

description: The volume of production and marketing of China’s conventional aquatic products is increasing. Compared with price of livestock and poultry products, price of conventional aquatic products is relatively low. Differentiated brand marketing for China’s conventional aquatic products is a key approach for increasing market demand for conventional aquatic products and increasing value of conventional aquatic products. The differentiated brand marketing is an inevitable trend of market development and also a powerful arm for market competition. China’s conventional aquatic products can take differentiated brand marketing strategies such as brand orientation, brand concept, brand culture, and place name brand, to better keep market competitive edge and increase economic benefits.

description: According to the group of intergovernmental experts on Climate Change (GIEC), climate changes will generate an increase in the number of atypical climate events throughout the world, such as droughts and floods. These climate anomalies could have disastrous consequences for countries that experience problems accessing drinking water or whose economy depends on local agriculture. Some recent studies even assert that drought is one of the causes of civil war. The most emblematic case is Darfur, as the present consensus is that drought was one of the factors of civil war, although the conflict also had an ethnic component. In our study, we show that the link between precipitation, temperature and civil war found in the literature may be due to planetary impacts not linked to climate variations. The problem is due to the impossibility of distinguishing the effects of annual climate variations from other planetary phenomena such as large-scale political changes like the end of Cold War or global macro-economic variations like financial crises. When we consider this type of factors, precipitation and temperature variations have a much lower and non-significant effect on the risk of civil war. The use of the Palmer index, a local drought measure which describes the impact of the lack of water on social conflicts, shows in a more satisfactory way than precipitation and temperature measures that the drought effect on civil war is low but positive.

description: Particular aspects of problems ranging from dielectric breakdown to metal insu- lator transition can be studied using electrical o elastic networks. We present an expression for the mean breakdown strength of such networks.First, we intro- duce a method to evaluate the redistribution of current due to the removal of a finite number of elements from a hyper-cubic network of conducatances.It is used to determine the reduction of breakdown strength due to a fracture of size $κ$.Numerical analysis is used to show that the analogous reduction due to random removal of elements from electrical and elastic networks follow a similar form.One possible application, namely the use of bone density as a diagnostic tools for osteorosporosis,is discussed.

description: Machine learning has the potential to accelerate materials discovery by accurately predicting materials properties at a low computational cost. However, the model inputs remain a key stumbling block. Current methods typically use descriptors constructed from knowledge of either the full crystal structure -- therefore only applicable to materials with already characterised structures -- or structure-agnostic fixed-length representations hand-engineered from the stoichiometry. We develop a machine learning approach that takes only the stoichiometry as input and automatically learns appropriate and systematically improvable descriptors from data. Our key insight is to treat the stoichiometric formula as a dense weighted graph between elements. Compared to the state of the art for structure-agnostic methods, our approach achieves lower errors with less data.
