description: This paper introduces ELUA, the Ecological Laboratory for Urban Agriculture, a collaboration among landscape architects, architects and computer scientists who specialize in artificial intelligence, robotics and computer vision. ELUA has two gantry robots, one indoors and the other outside on the rooftop of a 6-story campus building. Each robot can seed, water, weed, and prune in its garden. To support responsive landscape research, ELUA also includes sensor arrays, an AI-powered camera, and an extensive network infrastructure. This project demonstrates a way to integrate artificial intelligence into an evolving urban ecosystem, and encourages landscape architects to develop an adaptive design framework where design becomes a long-term engagement with the environment.

description: In this paper, we investigate synchronization in a small-world network of coupled nonlinear oscillators. This network is constructed by introducing random shortcuts in a nearest-neighbors ring. The local stability of the synchronous state is closely related with the support of the eigenvalue distribution of the Laplacian matrix of the network. We introduce, for the first time, analytical expressions for the first three moments of the eigenvalue distribution of the Laplacian matrix as a function of the probability of shortcuts and the connectivity of the underlying nearest-neighbor coupled ring. We apply these expressions to estimate the spectral support of the Laplacian matrix in order to predict synchronization in small-world networks. We verify the efficiency of our predictions with numerical simulations.

description: The statistics of the temperature anisotropies in the primordial cosmic microwave background radiation field provide a wealth of information for cosmology and for estimating cosmological parameters. An even more acute inference should stem from the study of maps of the polarization state of the CMB radiation. Measuring the extremely weak CMB polarization signal requires very sensitive instruments. The full-sky maps of both temperature and polarization anisotropies of the CMB to be delivered by the upcoming Planck Surveyor satellite experiment are hence being awaited with excitement. Multiscale methods, such as isotropic wavelets, steerable wavelets, or curvelets, have been proposed in the past to analyze the CMB temperature map. In this paper, we contribute to enlarging the set of available transforms for polarized data on the sphere. We describe a set of new multiscale decompositions for polarized data on the sphere, including decimated and undecimated Q-U or E-B wavelet transforms and Q-U or E-B curvelets. The proposed transforms are invertible and so allow for applications in data restoration and denoising.

The generation efficiency has been optimized by tuning the optical retardation of the q-plate with temperature. The measured OAM $m=\pm2$ eigenmodes generation efficiency from an input TEM$_{00}$ beam was of 97%. Mode sorting of the two input OAM $m=\pm2$ eigenmodes was achieved with an efficiency of 81% and an extinction-ratio (or cross-talk) larger than 4.5:1.

description: When human listeners try to guess the spatial position of a speech source, they are influenced by the speaker's production level, regardless of the intensity level reaching their ears. Because the perception of distance is a very difficult task, they rely on their own experience, which tells them that a whispering talker is close to them, and that a shouting talker is far away. This study aims to test if similar results could be obtained for prosodic variations produced by a human speaker in an everyday life environment. It consists in a localization task, during which blindfolded subjects had to estimate the incoming voice direction, speaker orientation and distance of a trained female speaker, who uttered single words, following instructions concerning intensity and social-affect to be performed. This protocol was implemented in two experiments. First, a complex pretext task was used in order to distract the subjects from the strange behavior of the speaker. On the contrary, during the second experiment, the subjects were fully aware of the prosodic variations, which allowed them to adapt their perception. Results show the importance of the pretext task, and suggest that the perception of the speaker's orientation can be influenced by voice intensity.

description: The accretion of matter onto a massive black hole is believed to feed the relativistic plasma jets found in many active galactic nuclei (AGN). Although some AGN accelerate particles to energies exceeding 10^12 electron Volts (eV) and are bright sources of very-high-energy (VHE) gamma-ray emission, it is not yet known where the VHE emission originates. Here we report on radio and VHE observations of the radio galaxy M87, revealing a period of extremely strong VHE gamma-ray flares accompanied by a strong increase of the radio flux from its nucleus. These results imply that charged particles are accelerated to very high energies in the immediate vicinity of the black hole.

description: In this paper, we study the dynamics of a viral spreading process in random geometric graphs (RGG). The spreading of the viral process we consider in this paper is closely related with the eigenvalues of the adjacency matrix of the graph. We deduce new explicit expressions for all the moments of the eigenvalue distribution of the adjacency matrix as a function of the spatial density of nodes and the radius of connection. We apply these expressions to study the behavior of the viral infection in an RGG. Based on our results, we deduce an analytical condition that can be used to design RGG's in order to tame an initial viral infection. Numerical simulations are in accordance with our analytical predictions.

description: Words Into Action requires evidence of disaster risk reduction (DRR) approaches and solid communication of that evidence through effective engagement with everyone in the science-policy-society ecosystem: policy makers, scientists and researchers, the private and non-profit sectors, the media, and ordinary people. Through our Disasters Avoided project, we are demonstrating the benefits of proactive DRR for everyone, including through the effective use of Earth observations, so that no one is left behind. Examples profiled here are wildland fires in Australia, cyclones in Bangladesh, and earthquakes across the east coast of the U.S.A. They show the importance of compiling, verifying, and sharing compelling good news of potential disasters which could have happened, but did not, because action was proactively taken based on knowledge and sound Earth observations data—as well as work remaining. We hope that these examples will inspire continuing action, based on repeated words, across all parts of society, including collaborative activities between Earth scientists and policy makers.

An evaluation of the "O skutecznym rad sposbie" of Stanislas Konarski

description: While the rest of eighteenth century Europe, with the exception of England, was subject to- autocratic rule, Poland enjoyed a rare privilege—that of electing the sovereign . In other respects, however, she was not to be envied. Politically she was no longer of consequence except as a pawn in the hands of foreign interests. Her great nobles and lesser gentry alike were content to bask in the remembered glory of past ages; clergymen were, for the most part, lazy, corrupt and ignorant; yeomen had been reduced to serfdom; there was no army to speak of; the towns were in decline; wars had depleted the treasury and commerce and trade hardly existed. Worst of all was a general apathy combined with devotionalism rather than religious fervour, and the spurious belief that God was on the side of Poland and would take care of her whether the Poles helped themselves or not. For some time, however, thinking men had worried about this state of affairs and many wrote down their ideas on the subject. It remained for a Piarist father, Stanislas Konarski, to attack the very root of the evil—bad forms of government in general, and the iniquitous unanimity principle in particular. His four-volume work, "0 Skutecznym Rad Sposobie" ("On Effective Counsels in Government"), which appeared in the 1760's, not only subjected the problem to minute analysis, but also offered a "prescription" for Poland's ills: but by the time the nation was ready to act on Konarski's ideas it had only a scant four years of freedom left. The fruits of his work were seen only after the First Partition.

description: Ageing of organic glasses to the equilibrium liquid state is studied by measuring the dielectric loss utilizing a microregulator where temperature is controlled by means of a Peltier element. Compared to conventional equipment the new device adds almost two orders of magnitude to the span of observable ageing times. Data for five organic glass-forming liquids are presented. The existence of an "inner clock" is confirmed by a model-free test showing that the ageing of structure is controlled by the same material time that controls the dielectric properties. At long times relaxation is not stretched, but simple exponential, and there is no "expansion gap" between the limits of the relaxation rates following up and down jumps to the same temperature.

description: The functioning of animal as well as human societies fundamentally relies on cooperation. Yet, defection is often favorable for the selfish individual, and social dilemmas arise. Selection by individuals' fitness, usually the basic driving force of evolution, quickly eliminates cooperators. However, evolution is also governed by fluctuations that can be of greater importance than fitness differences, and can render evolution effectively neutral. Here, we investigate the effects of selection versus fluctuations in social dilemmas. By studying the mean extinction times of cooperators and defectors, a variable sensitive to fluctuations, we are able to identify and quantify an emerging 'edge of neutral evolution' that delineates regimes of neutral and Darwinian evolution. Our results reveal that cooperation is significantly maintained in the neutral regimes. In contrast, the classical predictions of evolutionary game theory, where defectors beat cooperators, are recovered in the Darwinian regimes. Our studies demonstrate that fluctuations can provide a surprisingly simple way to partly resolve social dilemmas. Our methods are generally applicable to estimate the role of random drift in evolutionary dynamics.

description: Alkali atoms do not stably embed in liquid helium-4 because the interatomic attractive potential is unable to overcome the short-range Pauli repulsion of the s electrons and the surface tension cost of the surrounding bubble. Similarly, small alkali complexes reside on the surface of helium nanodroplets instead of inside. However, as the size of the metal cluster increases, its van der Waals attraction to the helium matrix grows faster than the repulsive energies and above a certain size it should become favorable for clusters to submerge in the liquid. Based on an evaluation of the relevant energy terms, we characterize the bubble dimensions and estimate the critical submersion sizes. The latter range from N~20 for Li_N and Na_N to N>100 for Rb_N in helium-4 and from N~5 for Li_N and Na_N to N~20 for Cs_N in helium-3. These results are discussed in the context of nanodroplet pick-up experiments with alkali atoms

title: Novel crop rotations to enhance the provision of multiple ecosystem services underpinning arable production
Creators: name: Degani, Erika
Publisher: name: University of Reading
Year: 2019

description: Given the challenges posed to agriculture by future climatic changes, the need to increase production due to a growing population and at the same time, reduce environmental impacts and preserve biodiversity, it is vital that more sustainable and resilient food production systems are in place. Ecological intensification is an approach proposed to partially replace external inputs (i.e. synthetic fertiliser and pesticides) with the provision of biodiversity derived ecosystem services, to either maintain or increase food production. One promising management practice is crop diversification, both temporally and spatially, which has the potential to improve the provision of multiple ecosystem services underpinning agricultural production and to confer resilience to food production systems. Studies conducted over three years, compared the ability of three 4-year crop rotations, along a diversity gradient (simple, moderate and diverse), to enhance the provision of multiple ecosystem services and increase resilience. The ability of each rotation to increase soil ecosystem services (soil fertility), pollination service, resilience under abiotic stresses and provide food resources for pollinators was assessed. Experiments were conducted at the University of Reading’s Crop Research Unit, Sonning, Berkshire, UK in a free draining sandy/silty loam overlaying coarse red-brown sand of the Sonning series. Berkshire has a temperate climate with annual mean temperatures ranging between 6.7 °C and 14.5°C. More diverse crop rotations resulted in higher nutrient cycling and consequently higher nutrient availability (mineral nitrogen) to the crops. However, this presented a trade-off with soil carbon storage in the short term. Increased crop diversity resulted in higher yield stability with reduced external inputs, under varying climatic conditions, with yield increases of 1 t/ha on average, and improved system resilience, but it did not increase the provision of soil fertility and pest regulation under abiotic stresses (heat and drought). Increased diversity and insect pollination had a positive impact on oilseed rape yield components and higher diversity also led to a more stable provision of nectar resources throughout the pollinator flight season, attracting more bumblebees than less diverse rotations. The results presented here suggest that crop diversification is likely to be an important tool in the ecological intensification of agriculture. However, it will need to be combined with other strategies, both at local (e.g. reduced tillage practices and flower strips) and at a landscape (e.g. diversification of flowering crops) level, if ecological intensification is to be implemented broadly and successfully. Results also highlight the urgent need for future long-term research on the potential benefits of crop diversification.
Strongly correlated metal interfaces in the Gutzwiller approximation

description: We study the effect of spatial inhomogeneity on the physics of a strongly correlated electron system exhibiting a metallic phase and a Mott insulating phase, represented by the simple Hubbard model. In three dimensions, we consider various geometries, including vacuum-metal-vacuum, a junction between a weakly and a strongly correlated metal, and finally the double junctions metal-Mott insulator-metal and metal-strongly correlated metal- metal. We applied to these problems the self-consistent Gutzwiller technique recently developed in our group, whose approximate nature is compensated by an extreme flexibility,ability to treat very large systems, and physical transparency. The main general result is a clear characterization of the position dependent metallic quasiparticle spectral weight. Its behavior at interfaces reveals the ubiquitous presence of exponential decays and crossovers, with decay lengths of clear physical significance. The decay length of metallic strength in a weakly-strongly correlated metal interface is due to poor screening in the strongly correlated side. The decay length of metallic strength from a metal into a Mott insulator (or into vacuum) is due to tunneling. In both cases, the decay length is a bulk property, and diverges with a critical exponent ($\sim 1/2$ in the present approximation, mean field in character) as the (continuous, paramagnetic) Mott transition is approached.

description: Optical flow estimation is crucial for autonomous navigation and localization of unmanned aerial vehicles (UAV). On micro and nano UAVs, real-time calculation of the optical flow is run on low power and resource-constrained microcontroller units (MCUs). Thus, lightweight algorithms for optical flow have been proposed targeting real-time execution on traditional single-core MCUs. This paper introduces an efficient parallelization strategy for optical flow computation targeting new-generation multicore low power RISC-V based microcontroller units. Our approach enables higher frame rates at lower clock speeds. It has been implemented and evaluated on the eight-core cluster of a commercial octa-core MCU (GAP8) reaching a parallelization speedup factor of 7.21 allowing for a frame rate of 500 frames per second when running on a 50 MHz clock frequency. The proposed parallel algorithm significantly boosts the camera frame rate on micro unmanned aerial vehicles, which enables higher flight speeds: the maximum flight speed can be doubled, while using less than a third of the clock frequency of previous single-core implementations.

description: In this paper, a cooperative localization algorithm is proposed that considers the existence of obstacles in mobilityassisted wireless sensor networks (WSNs). In this scheme, a mobile anchor (MA) node cooperates with static sensor nodes and moves actively to refine location performance. The localization accuracy of the proposed algorithm can be improved further by changing the transmission range of mobile anchor node. The algorithm takes advantage of cooperation betweenMAs and static sensors while, at the same time, taking into account the relay node availability to make the best use of beacon signals. For achieving high localization accuracy and coverage, a novel convex position estimation algorithm is proposed, which can effectively solve the localization problem when infeasible points occur because of the effects of radio irregularity and obstacles. This method is the only range-free based convex method to solve the localization problem when the feasible set of localization inequalities is empty. Simulation results demonstrate the effectiveness of this algorithm.

A multifrequency study of giant radio sources III. Dynamical age vs. spectral age of the lobes of selected sources

description: The dynamical ages of the opposite lobes of selected giant radio sources are estimated using the DYNAGE algorithm of Machalski et al., and compared with their spectral ages estimated and studied by Jamrozy et al. in Paper II. As expected, the DYNAGE fits give slightly different dynamical ages and other model's parameters for the opposite lobes modelled independently each other, e.g. the age ratios are found between ~1.1 to ~1.4. Demanding similar values of the jet power and the radio core density for the same source, we look for a self-consistent solution for the opposite lobes, which results in different density profiles along them found by the fit. We also show that a departure from the equipartition conditions assumed in the model, justified by X-ray observations of the lobes of some nearby radio galaxies, and a relevant variation of the magnetic-field strengths may provide an equalisation of the lobes' ages. A comparison of the dynamical and spectral ages shows that a ratio of the dynamical age to the spectral age of the lobes of investigated giant radio galaxies is between ~1 and ~5, i.e. is similar to that found for smaller radio galaxies (e.g. Parma et al. 1999). Supplementing possible causes for this effect already discussed in the literature, like uncertainty of assumed parameters of the model, an influence of a possible departure from the energy equipartition assumption, etc. Arguments are given to suggest that DYNAGE can better take account of radiative effects at lower frequencies than the spectral-ageing analysis.The DYNAGE algorithm is especially effective for sources at high redshifts, for which an intrinsic spectral curvature is shifted to low frequencies.

Un cratere porta traccia di formazioni geologiche più recenti dell’ultima glaciazione. L’acqua su Marte avrebbe meno di 200.000 anni. Lo dice uno studio dell’Università di Göteborg che per capire meglio i fenomeni di dilavamento marziani è andata a studiare le frane e i calanchi delle isole Svalbard
Momentum dependence of the spin susceptibility in two dimensions: nonanalytic corrections in the Cooper channel

description: We consider the effect of rescattering of pairs of quasiparticles in the Cooper channel resulting in the strong renormalization of second-order corrections to the spin susceptibility in a two-dimensional electron system. We use the Fourier expansion of the scattering potential in the vicinity of the Fermi surface to find that each harmonic becomes renormalized independently. Since some of those harmonics are negative, the first derivative of the spin susceptibility is bound to be negative at small momenta, in contrast to the lowest order perturbation theory result, which predicts a positive slope. We present in detail an effective method to calculate diagrammatically corrections to the spin susceptibility to infinite order.
