subject: Tree improvement (incl. selection and breeding)

description: Juniperus sabina is an interesting species for forest restoration and ornamental purposes. Theseeds of this plant have several types of dormancies; therefore, seed propagation is difficult and timeconsuming. The production of cuttings can be an alternative way to produce plants more quickly. Themain objective of this experiment was to determine the best propagation conditions (indole butyricacid dose, substrate, and season) for this species using stem cuttings. Rooting performance of thecuttings was evaluated based on the rooting percentage (%), root biomass, and specific root length(SRL). In addition, we examined the internal composition (auxin and peroxidase content) in treatedstem cuttings. Cuttings were pretreated with five doses of indole butyric acid (IBA; 0 (control), 1000,2000, 4000, and 8000 ppm) and were rooted in four substrates (perlite, perlite-cocopeat, pumice, andmixed substrate) during the four seasons (winter, spring, summer, and autumn). The best treatments,with more than 60% rooting, were applied in spring, and IBA at 1000 ppm in perlite–cocopeatsubstrate obtained 62% rooting. The highest rooting percentage correlated with the highest rootbiomass production and the lowest SRL. IBA pretreatment decreased the concentration of peroxidasein spring (coinciding with maximum rooting), representing an indicator of rooting performance.Based on these results, we recommend a new protocol for Juniperus sabina production: (i) preparecuttings in spring, (ii) treat cutting bases with 1000 ppm IBA, and (iii) plant cuttings in a substrate ofperlite–cocopeat (1:1).
title: Integral abutment bridge design with thin-walled prestressed precast bridge girders

description: Bridge construction has always been part of structural engineering, and has been evolving throughout the years. New construction technologies have been discovered to better use materials and construction techniques. Precast concrete is one of these evolving techniques that are being utilized more and more nowadays. The motivation behind this project is the use of prestressed precast concrete as a realistic replacement to composite construction of bridges. An existing composite overpass bridge, between the Austrian states of Upper Austria and Salzburg, is taken as a starting point to find out if it is possible to build a bridge with an equivalent bending stiffness with use of thin-walled prestressed precast bridge girders. These bridge girders allow the slenderness of the bridge to stay almost unchanged while decreasing the heavy weights having to be moved around during the construction of the bridge. The structural analysis of the bridge was carried out by first analyzing a 2-dimensional model to better approximate the prestress needed on each construction phase. Additionally a 3-D analysis was performed on a more accurate model to give the final internal forces with help of the software RFEM from Dlubal and with an excel spreadsheet programed to find the internal stresses on the girders of the structure. This research illustrates the plausibility of using prestressed precast concrete as a technique in order to build an overpass bridge with a span of ca. 47 m. The design was achieved by modeling the construction of the bridge in 5 construction phases. These phases help illustrate the internal forces at different points on the girders and the bridge's slab due to self weight as well as the prestressing loads being applied on the built in tendons. The research performed for this project is an addition to ongoing research on prestressed precast bridge construction at the Vienna University of Technology, but it already shows great potential to use prestress precast concrete

description: The cluster multipole (CMP) expansion for magnetic structures provides a scheme to systematically generate candidate magnetic structures specifically including noncollinear magnetic configurations adapted to the crystal symmetry of a given material. A comparison with the experimental data collected on MAGNDATA shows that the most stable magnetic configurations in nature are linear combinations of only few CMPs. Furthermore, a high-throughput calculation for all candidate magnetic structures is performed in the framework of spin-density functional theory (SDFT). We benchmark the predictive power of CMP+SDFT with $2935$ calculations, which show that (i) the CMP expansion administers an exhaustive list of candidate magnetic structures, (ii) CMP+SDFT can narrow down the possible magnetic configurations to a handful of computed configurations, and (iii) SDFT reproduces the experimental magnetic configurations with an accuracy of $\pm0.5\,μ_\text{B}$. For a subset the impact of on-site Coulomb repulsion $U$ is investigated by means of $1545$ CMP+SDFT+U calculations revealing no further improvement on the predictive power.

Tailored scaffolding for meta-cognitive skills during analogical problem solving
Creators: name: Muldner, Katarzyna
Publisher: name: University of British Columbia
Year: 2011

description: Although examples play a key role in cognitive skill acquisition, research demonstrates that learning outcomes are heavily influenced by the meta-cognitive skills students bring to bear while using examples. This dissertation involves the design, implementation and evaluation of the Example Analogy (EA)-Coach, an Intelligent Tutoring System that provides adaptive support for meta-cognitive skills during a specific type of example-based learning known as analogical problem solving (APS, using examples to aid problem solving). To encourage the targeted meta-cognitive skills, the EA-Coach provides multiple levels of scaffolding, including an innovate example-selection mechanism that aims to choose examples with the best potential to trigger learning and enable problem solving for a given student. To find such examples, a key factor that needs to be taken into account is problem/example similarity, because it impacts the APS process. However, full understanding has yet to be reached on how various levels of similarity between a problem and an example influence students' APS behaviours and subsequent outcomes. Here, we provide a novel classification of problem/example differences and hypotheses regarding their impact on APS. In particular, we propose that certain differences between a problem and an example may actually be beneficial in helping students learn from APS, because they promote the necessary meta-cognitive skills. However, given the great variance in terms of knowledge and meta-cognitive skills that exists between students, a key challenge with our approach is how to select examples that provide enough scaffolding for different learners. Our solution to this challenge involves a two-step decision-theoretic process. First, the EA-Coach student model, which corresponds to a dynamic Bayesian network, is used to predict how a candidate example will help a student solve the problem and learn from doing so. Second, the model's prediction is quantified via a utility function, which assigns an expected utility to the candidate example. This process allows the framework to present to the student the example with the highest expected utility for enabling learning and problem solving. We evaluated this approach via a controlled laboratory study, which demonstrated the EA-Coach's pedagogical effectiveness for supporting problem solving and triggering meta-cognitive skills needed for learning during APS.

The work takes up a series of issues pertaining to the monetary interpretation of Friedman and Simons. The authors find that espousal of a monetary rule involves, foremost, confidence in the extrapolability of long-term statistical trends, particularly with respect to velocity. The initial formulation of the monetary hypothesis of the Great Depression is linked to an entirely overlooked original contribution by William Foster and Waddill Catchings. Their contribution these authors essentially anticipates views set forth by Friedman and Simons, and already included the formulation of the monetary growth-rate rule. JEL: B31, E40

description: We study Landau-Zener macroscopic quantum transitions in ferromagnetic metal nanoparticles containing on the order of 100 atoms. The model that we consider is described by an effective giant-spin Hamiltonian, with a coupling to a random transverse magnetic field mimicking the effect of quasiparticle excitations and structural disorder on the gap structure of the spin collective modes. We find different types of time evolutions depending on the interplay between the disorder in the transverse field and the initial conditions of the system. In the absence of disorder, if the system starts from a low-energy state, there is one main coherent quantum tunneling event where the initial-state amplitude is completely depleted in favor of a few discrete states, with nearby spin quantum numbers; when starting from the highest excited state, we observe complete inversion of the magnetization through a peculiar ``backward cascade evolution''. In the random case, the disorder-averaged transition probability for a low-energy initial state becomes a smooth distribution, which is nevertheless still sharply peaked around one of the transitions present in the disorder-free case. On the other hand, the coherent backward cascade phenomenon turns into a damped cascade with frustrated magnetic inversion.

description: The effect of a stochastic displacement field on a statistically independent point process is analyzed. Stochastic displacement fields can be divided into two large classes: spatially correlated and uncorrelated. For both cases exact transformation equations for the two-point correlation function and the power spectrum of the point process are found, and a detailed study of them with important paradigmatic examples is done. The results are general and in any dimension. A particular attention is devoted to the kind of large scale correlations that can be introduced by the displacement field, and to the realizability of arbitrary ``superhomogeneous'' point processes.

description: Accurate modeling of opinion dynamics has the potential to help us understand polarization and what makes effective political discourse possible or impossible. Here, we use physics-based methods to model the evolution of political opinions within a continuously distributed population. We utilize a network-free system of determining political influence and a local-attraction, distal-repulsion dynamic for reaction to perceived content. Our approach allows for the incorporation of intergroup bias such that messages from trusted in-group sources enjoy greater leeway than out-group ones. We are able to extrapolate these nonlinear microscopic dynamics to macroscopic population distributions by using probabilistic functions representing biased environments. The framework we put forward can reproduce real-world political distributions and experimentally observed dynamics, and is amenable to further refinement as more data becomes available.

description: Scalar field models with non-standard kinetic terms have been proposed in the context of k-inflation, of Born-Infeld lagrangians, of phantom energy and, more in general, of low-energy string theory. In general, scalar fields are expected to couple to matter inducing a new interaction. In this paper I derive the cosmological perturbation equations and the Yukawa correction to gravity for such general models. I find three interesting results: first, when the field behaves as phantom energy (equation of state less than -1) then the coupling strength is negative, inducing a long-range repulsive force; second, the dark energy field might cluster on astrophysical scales; third, applying the formalism to a Brans-Dicke theory with general kinetic term it is shown that its Newtonian effects depend on a single parameter that generalizes the Brans-Dicke constant.

description: We present the results of a detailed analysis of the XMM-Newton observation of the galaxy cluster Abell 3921. The X-ray morphology of the cluster is elliptical, with the centroid offset from the brightest cluster galaxy by 17 arcsec, and with a pronounced extension toward the NW. Subtraction of a 2D beta model fit to the main cluster emission reveals a large scale, irregular residual structure in the direction of the extension, containing both diffuse emission from the intra cluster medium, and extended emission from the second and third-brightest cluster galaxies (BG2 and BG3). The greatest concentration of galaxies in the subcluster lies at the extreme northern edge of the residual. The cluster exhibits a remarkable temperature structure, in particular a bar of significantly hotter gas, oriented SE-NW and stretching from the centre of the cluster towards BG2 and BG3. Our detailed study of the morphological and thermal structure points to an off-axis merger between a main cluster and a less massive galaxy cluster infalling from the SE. From comparison of the temperature map with numerical simulations, and with independent calculations based on simple physical assumptions, we conclude that the merging event is ~0.5 Gyr old. The cluster is thus perhaps the best X-ray observed candidate so far of an intermediate mass ratio, moderate impact parameter merger.

Multiphoton interaction phase shifts in attosecond science

Year: 2020
Subjects: subject: Atomic Physics (physics.atom-ph)

description: Ab initio simulations of a range of interferometric experiments are used to identify a strong dependence on multiphoton phase shifts in above-threshold ionization. A simple rule of thumb for interaction phase shifts is derived to explain both the conservation of photoelectron yield and its absolute CEP-dependence. For instance, it is found that interferometric above-threshold ionization experiments are shifted by $π/4$ relative to RABBIT experiments, and that there is no RABBIT-term in a laser-assisted photoionization experiment with odd and even harmonics. Thus, our work helps to resolve the issues of interpretation of quantum dynamics in attosecond and free-electron laser sciences.

Alla semplicità del provvedimento non h a, tuttavia, corrisposto uguale chiarezza delle sue implicazioni.

description: Boundary obstructed topological insulators are an unusual class of higher-order topological insulators with topological characteristics determined by the so-called Wannier bands. Boundary obstructed phases can harbor hinge/corner modes, but these modes can often be destabilized by a phase transition on the boundary instead of the bulk. While there has been much work on the stability of topological insulators in the presence disorder, the topology of a disordered Wannier band, and disorder-induced Wannier transitions have not been extensively studied. In this work, we focus on the simplest example of a Wannier topological insulator: a mirror-symmetric $π$-flux ladder in 1D. We find that the Wannier topology is robust to disorder, and derive a real-space renormalization group procedure to understand a new type of strong disorder-induced transition between non-trivial and trivial Wannier topological phases. We also establish a connection between the Wannier topology of the ladder and the energy band topology of a related system with a physical boundary cut, something which has generally been conjectured for clean models, but has not been studied in the presence of disorder.

description: A Közös Agrárpolitika keretein belül nyújtott mezőgazdasági támogatások jelentős hatást fejtenek ki a gazdálkodási gyakorlatra, amely befolyásolja az ágazat által előállított közjavak mennyiségét. Mivel az eddigi tanulmányok azt bizonyítják, hogy jelenleg a mezőgazdaság a társadalmi elvárásoknál kevesebb közjót termel, ezért az ágazat közjótermelő képessége is egyre inkább az érdeklődés homlokterébe kerül. Cikkünkben a közjavak különféle meghatározásainak áttekintésén túlmenően rendszerezzük a mezőgazdasághoz kötődő környezeti és társadalmi közjavak tekintetében megfogalmazott véleményeket és bemutatjuk e közjavak értékelésének problémáit. Az alapvető problémát az okozza, hogy ezeknek a javaknak nincsen piaca, és ezáltal nincsen áruk sem. Megoldást a mesterséges piacok kialakítása jelenthet, melyre közgazdasági szempontból több lehetőség kínálkozik a környezetvédelmi előírások, környezetvédelmi adók, értékesíthető engedélyek rendszerén keresztül az agrár-környezetvédelmi kifizetésekig. A közjavak optimális szinten történő előállításához a különböző eszközök együttes alkalmazása szükséges, azonban ennek előfeltétele az előállított közjavak mennyiségére vonatkozó mérési módszerek kidolgozása. -------------- Agricultural subsidies provided through the framework of the Common Agricultural Policy have a remarkable influence on farming activities which determine the quantity of public goods produced by agriculture. Recent studies argue that the social demand for public goods is undersupplied by agriculture. Investigating the ability of agriculture to provide public goods is therefore gaining increasing attention. In our article we give an overview of the definition of public goods, the types of environmental and social public goods provided by agriculture and the problems of their evaluation. The main problem is that these goods have no market and as a result of this they lack prices. One solution would be to create an artificial market for them by introducing environmental standards, environmental taxes, tradable permits and agri-environmental payments. To guarantee the optimal provision of public goods a combination of the above mentioned tools is needed. However, the pre-requisite of this is the development of reliable measurement methods for these goods.

Számításokkal igazoltuk, hogy a zöldenergia-felhasználás arányainak növeléséhez a kisméretű tejtermelő tehenészetek is képesek hozzájárulni. A napenergia hasznosításával a tehenészetek villamosenergia-igényének 100%-át lehetséges fizikailag fedezni. Kutatásunkban arra a gazdasági kérdésre keressük a választ, hogy érdemes-e, és ha igen, akkor mekkora méretű napelemes rendszert telepítenie egy hazai tehenészetnek. Eredményeink alapján a napelemes rendszer beruházása megtérül, azonban a kockázati tényezők elemzésére kiemelt figyelmet szükséges fordítani. A napelemes rendszerek 15 éves üzemelési idejük alatt a hazai 10-100 tehénből álló gazdaságoknál összesen mintegy 1,4 milliárd Ft költségmegtakarítást eredményezhetnek, ami jelentősen növelhetné a 10-100 állománylétszámú tehenészetek versenyképességét. -------------- The characteristics of dairy farms have been studied in this paper and a solution has been sought for photovoltaic energy use on small dairy farms (10-100 cows). The calculations in this study show that the small dairy farms can really produce green energy. Solar energy can meet 100 per cent of energy needs of these farms. This solar system project is profitable. During 15 years of use of solar systems about HUF 1.4 billion could be realised in cost savings. This amount of money could increase the competitiveness of the dairy farms with 10-100 cows.

MAXI

description: The Monitor of All-sky X-ray Image (MAXI) experiment is mounted to the Japanese Experiment Module on the International Space Station (ISS) and uses several wide field-of-view X-ray detectors to monitor astronomical X-ray sources for variability, scanning the sky every 92-minute ISS orbit. As a result of this investigation, we present "MAXI Analyzer", a fully automated online data retrieval and command-line processing algorithm (soon publicly available). "MAXI Analyzer" provides the user with science-ready, cleaned data products in the 2--20 keV energy band from the Gas Slit Camera. These can then be used to calculate hardness ratio curves, long-term light curves and ultimately help in constraining stellar wind parameters from *any* X-ray binary system. We have tested this software on over 12 years of Vela X-1 data to probe its long-term absorption variability and compare to existing theoretical model predictions. Also, we show how MAXI's resolution allows orbital classification according to observed pattterns in flux variation. The goal (in progress) is to infer NH based on a theoretical spectrum and the MAXI response. These observations can further be complemented with detailed pointed observations by XMM-Newton and in the future Athena.

description: Machine reading comprehension (MRC) is a challenging task in natural language processing that makes computers understanding natural language texts and answer questions based on those texts. There are many techniques for solving this problems, and word representation is a very important technique that impact most to the accuracy of machine reading comprehension problem in the popular languages like English and Chinese. However, few studies on MRC have been conducted in low-resource languages such as Vietnamese. In this paper, we conduct several experiments on neural network-based model to understand the impact of word representation to the Vietnamese multiple-choice machine reading comprehension. Our experiments include using the Co-match model on six different Vietnamese word embeddings and the BERT model for multiple-choice reading comprehension. On the ViMMRC corpus, the accuracy of BERT model is 61.28% on test set.

description: Il presente lavoro valuta l'importanza della domanda privata di obbligazioni, soprattutto nel contesto italiano, nella preparazionee e gestione di interventi da parte delle autorità monetarie. La corretta identificazione e la quantificazione dei fattori che determinano la domanda di obbligazioni da parte dell'economia permette, tra le altre cose, per fare previsioni con maggiore precisione e validità, per distinguere più facilmente variazioni momentanee da cambiamenti profondi e di adeguare gli obiettivi di politica monetaria e le linee di azione con maggiore sicurezza. L'analisi mira a fornire un anticipo teorico rispetto alle stime tradizionali della domanda di obbligazioni (ancora in uso nei paesi anglosassoni). La prima parte, che presenta le stime annuali della domanda, collega il momento della decisione sul risparmio totale per la scelta tra le attività finanziarie diverse. La seconda parte, che presenta le stime trimestrali, promuove il dibattito sul tasso di interesse, che unisce le due principali teorie esistenti, quelli di I. Fisher e K. Wicksell. The present work evaluates the importance of the private demand for bonds, especially in the Italian context, in the preparation and and management of interventions by the monetary authorities. The correct identification and quantification of the factors that determine the demand for bonds by the economy allows, among other things, to make predictions with greater precision and validity, to more easily distinguish momentary variations from deeper changes and to adjust monetary policy objectives and lines of action with greater security. The analysis seeks to provide a theoretical advance with respect to traditional estimates of the demand for bonds (still used in Anglo-Saxon countries). The first part, which presents the annual estimates of the demand, connects the time of the decision on the total savings when choosing between different financial assets. The second part, which presents the quarterly estimates, furthers the discussion on the interest rate, combining the two main existing theories, those of I. Fisher and K. Wicksell. JEL: G12, E52, E58

description: We consider the $N$-components 3-dimensional massive Gross-Neveu model compactified in one spatial direction, the system being constrained to a slab of thickness $L$. We derive a closed formula for the renormalized $L$-dependent four-point function at vanishing external momenta in the large-N limit (the effective coupling constant), using bag-model boundary conditions. For values of the fixed coupling constant in absence of boundaries $λ\geq λ_c \simeq 19.16$, we obtain small-distance asymptotic freedom (for $L \to 0$) and a singularity for a length $L^{(c)}$ such that $2.07 m^{-1} < L^{(c)} \lesssim 2.82 m^{-1}$, $m$ being the fermionic mass. Taking for $m$ an average of the masses of the quarks composing the proton, we obtain a "confining" length $L^{(c)}_p$ which is comparable with an estimated proton diameter.

Noisy distributed sensing in the Bayesian regime

description: We consider non-local sensing of scalar signals with specific spatial dependence in the Bayesian regime. We design schemes that allow one to achieve optimal scaling and are immune to noise sources with a different spatial dependence than the signal. This is achieved by using a sensor array of spatially separated sensors and constructing a multi-dimensional decoherence free subspace. While in the Fisher regime with sharp prior and multiple measurements only the spectral range $Δ$ is important, in single-shot sensing with broad prior the number of available energy levels $L$ is crucial. We study the influence of $L$ and $Δ$ also in intermediate scenarios, and show that these quantities can be optimized separately in our setting. This provides us with a flexible scheme that can be adapted to different situations, and is by construction insensitive to given noise sources.

Subjects: subject: Exchange rate system, financial arrangements, EEC, European integration, trade, adjustment rules
subject: E42, F36, F33

description: The Jamaica Agreement essentially grants every country the freedom to determine its own exchange rate system, thus confirming a situation characterised by a wide variety of national arrangements. This situation has given rise to considerable uncertainty as regards trade and capital movements. The present work argues that greater stability in financial arrangements among the EEC countries would reduce uncertainty and contribute to harmonious economic development in the European area. Specifically, the author makes proposals for the adoption of a three-pronged approach to lessening uncertainty in trade and payments and to strengthening the European integration process. The proposals include establishing rules for exchange rate adjustments, harmonising national economic policies and creating a parallel currency, the Europa. JEL: E42, F36, F33

Realistic materials and illumination environments
Creators: name: Ghosh, Abhijeet
Publisher: name: University of British Columbia
Year: 2011

description: Throughout its history, the field of computer graphics has been striving towards increased realism. This goal has traditionally been described by the notion of photo-realism, and more recently and in many cases the more ambitious goal of perceptual realism. Photo-realistic image synthesis involves many algorithms describing the phenomena of light transport in a scene as well as its interaction with various materials. On the other hand, research in perceptual realism typically involves various tone mapping algorithms for display devices as well as algorithms that mimic the natural response of the human visual system in order to recreate the visual experience of a real scene. An important aspect of realistic rendering is the accurate modeling of the scene elements such as light sources and material reflectance properties. This dissertation proposes a set of new techniques for efficient acquisition of material properties as well as new algorithms for high quality rendering with acquired data. Here, we are mostly concerned with the acquisition and rendering of local illumination effects. In particular, we propose a new optical setup for efficient acquisition of the bidirectional reflectance distribution function (BRDF) with basis illumination and various Monte Carlo strategies for efficient sampling of direct illumination. The dissertation also looks into the display end of the image synthesis pipeline and proposes algorithms for displaying scenes on high dynamic range (HDR) displays for visual realism, and for tying the room illumination with the viewing environment for a sense of presence and immersion in a virtual environment. Here, we develop real-time rendering algorithms for driving the HDR displays as well as for active control of room illumination based on dynamic scene content. Thus, we propose contributions to the acquisition, rendering, and display end of the image synthesis pipeline while targeting real-time rendering applications, as well as high quality off-line rendering with realistic materials and illumination environments.

description: The work deals with the reform of the International monetary system, the end result of four years of laborious negotiations. The author agrees with the majority of commentators that relatively little has been accomplished. He differs from them, however, in two major respects. The first regards the evaluation of the limited results. The second regards the direction in which, under the circumstances, efforts could have been more profitably directed. General comments are provided on both of these points. Then, proposals which concern chiefly the monetary system, but also cover the international financial system, are outlined. JEL: E42, F33

A New Family of Light Beams and Mirror Shapes for Future LIGO Interferometers

description: Advanced LIGO's present baseline design uses arm cavities with Gaussian light beams supported by spherical mirrors. Because Gaussian beams have large intensity gradients in regions of high intensity, they average poorly over fluctuating bumps and valleys on the mirror surfaces, caused by random thermal fluctuations (thermoelastic noise). Flat-topped light beams (mesa beams) are being considered as an alternative because they average over the thermoelastic fluctuations much more effectively. However, the proposed mesa beams are supported by nearly flat mirrors, which experience a very serious tilt instability. In this paper we propose an alternative configuration in which mesa-shaped beams are supported by nearly concentric spheres, which experience only a weak tilt instability. The tilt instability is analyzed for these mirrors in a companion paper by Savov and Vyatchanin. We also propose a one-parameter family of light beams and mirrors in which, as the parameter alpha varies continuously from 0 to pi, the beams and supporting mirrors get deformed continuously from the nearly flat-mirrored mesa configuration ("FM") at alpha=0, to the nearly concentric-mirrored mesa configuration ("CM") at alpha=pi. The FM and CM configurations at the endpoints are close to optically unstable, and as alpha moves away from 0 or pi, the optical stability improves.
