description: We study unsteady internal flows in a sessile droplet of capillary size evaporating in constant contact line mode on a heated substrate. Three-dimensional simulations of internal flows in evaporating droplets of ethanol and silicone oil have been carried out. For describing the Marangoni flows we find it necessary to account for the diffusion of vapor in air, the thermal conduction in all three phases and thermal radiation. The equations have been solved numerically by finite element method using ANSYS Fluent. As a result of the simulations, the nonstationary behavior of Bénard-Marangoni (BM) instabilities is obtained. At the first stage, a flower structure of BM cells near the triple line emerge. For smaller contact angles, the cells grow in size and occupy the central region of the droplet surface. Being closely connected with recent experimental and theoretical studies, the results obtained help to analyze and resolve the associated issues.

General Elections

description: The upcoming Papua New Guinea (PNG) national general elections, scheduled to run from April through July 2022, are worrying, due to concerns not only about the health of Papua New Guineans but also the health of PNG’s democracy. In PNG, elections — held every five years — are one of the only occasions when citizens actively engage with the state on a nationwide scale. It is a period of high activity and mobility. In the midst of the pandemic, there are certain electiontime behaviours that make them likely superspreader events. Drawing from the experiences of two recent byelections in Goroka and Port Moresby North West, this In Brief examines some of the risks and implications associated with conducting elections during the time of COVID-19 as well as some of the negative aspects of PNG elections that might reoccur in 2022.

description: Abstract

This study focused on the effect of external debt burden on human development index among the West African Monetary Zone countries. It sought to assess the significance of external debt burden, and to suggest measures that could enhance its effectiveness and human development in West African Monetary Zone. To achieve the objective of the research, some macroeconomic and human development indicators, using the ex-post facto research design was applied. The population and the sample size of the study comprised of six (6) ECOWAS countries that make up the West African Monetary Zone. The data were collated, analyzed and tested using descriptive statistics, country-specific and the panel data ARDL analysis techniques. From the analysis, it was revealed that external debt service payment and external debt both significantly affect human development index though adversely in the Gambia, Ghana, Guinea, Liberia, Nigeria and Sierra Leone. This implies that education, health and per capital income which are the components of the Human Development Index (HDI) deteriorates as the level of revenue that goes to debt servicing gets higher. This also happens as more debts are contracted especially above the size of most West African Monetary Zone member economies.  Based on the findings, the study recommended that the external debt thresholds should be considered by the Ghanaian economy when formulating their external debt management policies, thereby reducing their reliance on external debt funds. Domestically generated revenue, especially tax revenue, should be revamped and galvanized, in such a way that tax avoidance and evasion would be reduced drastically, to bridge the resulting gap in expenditure. Also, to mitigate the adverse effect of external debt and its corresponding payment obligation, the Nigerian government should sort for loans with favourable terms and conditions after a rigorous evaluation, not on exigency, to reduce the cost of the debt. A well-developed capital market will reduce the rate of external borrowing.

description: We consider the use of probabilistic neural networks for fluid flow {surrogate modeling} and data recovery. This framework is constructed by assuming that the target variables are sampled from a Gaussian distribution conditioned on the inputs. Consequently, the overall formulation sets up a procedure to predict the hyperparameters of this distribution which are then used to compute an objective function given training data. We demonstrate that this framework has the ability to provide for prediction confidence intervals based on the assumption of a probabilistic posterior, given an appropriate model architecture and adequate training data. The applicability of the present framework to cases with noisy measurements and limited observations is also assessed. To demonstrate the capabilities of this framework, we consider canonical regression problems of fluid dynamics from the viewpoint of reduced-order modeling and spatial data recovery for four canonical data sets. The examples considered in this study arise from (1) the shallow water equations, (2) a two-dimensional cylinder flow, (3) the wake of NACA0012 airfoil with a Gurney flap, and (4) the NOAA sea surface temperature data set. The present results indicate that the probabilistic neural network not only produces a machine-learning-based fluid flow {surrogate} model but also systematically quantifies the uncertainty therein to assist with model interpretability.

description: We investigate a general structure theory for a vertex operator algebra. We discuss the center and blocks, the Jacobson radical and solvable radical and local vertex operator algebras. The main consequence of our structure theory is that if the vertex operator algebra satisfies some mild conditions then it is necessarily semilocal, i.e. a direct sum of local vertex operator algebras.

description: HEALPix -- the Hierarchical Equal Area iso-Latitude Pixelization -- is a versatile data structure with an associated library of computational algorithms and visualization software that supports fast scientific applications executable directly on very large volumes of astronomical data and large area surveys in the form of discretized spherical maps. Originally developed to address the data processing and analysis needs of the present generation of cosmic microwave background (CMB) experiments (e.g. BOOMERanG, WMAP), HEALPix can be expanded to meet many of the profound challenges that will arise in confrontation with the observational output of future missions and experiments, including e.g. Planck, Herschel, SAFIR, and the Beyond Einstein CMB polarization probe. In this paper we consider the requirements and constraints to be met in order to implement a sufficient framework for the efficient discretization and fast analysis/synthesis of functions defined on the sphere, and summarise how they are satisfied by HEALPix.

description: Im Rahmen der vorliegenden Arbeit werden Silizium Teilchendetektoren zur Überprüfung ihrer Verwendbarkeit in einem großen Teilchenphysik Experiment einem Strahltest am Super Proton Synchrotron des CERN unterzogen. Zuerst erfolgt eine Zusammenfassung der Wirkungsweise der Detektoren, dem Aufbau des Auslesesystems und des Experiments sowie des Verhaltens der Detektoren bei Auftreten von Strahlenschäden. Zur Auswertung der Daten dieses Strahltests wird des Weiteren Software zur Datenauswertung um Anpassungsmodule, Berechnungsmodule für Signal-Rauschabstand und die Ausgabe der Daten erweitert sowie einige bestehende Komponenten angepasst. Da aus früheren Messungen Fertigungsfehler an den Detektoren vermutet werden und das Verhalten nach der Aufnahme einer erhöhten Strahlendosis im laufenden Betrieb für die Charakterisierung der Detektoren relevant ist, erfolgte danach eine Bestrahlung der Detektoren an einer Co60 Gammaquelle sowie darauffolgend ein erneuter Strahltest. Im letzten Schritt erfolgt die Interpretation der Ergebnisse in Bezug auf die Leistungsfähigkeit der Detektoren, der Effekte der Bestrahlung auf diese sowie der Effekte der Bestrahlung auf auftretende Fehler und ein Vergleich mit parallel ausgeführten elektrischen Messungen.
description: In this diploma thesis the usability of particle detectors for their use in a large particle physics experiment is verified. For this verification they are used during a beamtest at the super proton synchrotron at CERN. First there is a description of the mode of operation and interactions of particles with the detectors, the readout system as well as the experiment and the characeristic damages of silicon particle detectors under irradiation. To analyze the data, software will be extended by fitting modules, calculation modules for signal to noise (SNR) ratio and new reporting modules. Additionally existing components will be modified to be able to analyze the data. Because there has been a speculation about errors accounted for by the fabrication process and because the behaviour of the detectors after irradiation is essential for characterisation of particle detectors, the detectors have been irradiated at an Co60 gamma source. This irradiation was followed by another beamtest. At the end there is an interpretation of the results according to the performance and effects of the irradiation as well as an interpretation according to the suspected manufactoring errors. Results also will be compared to electrical measurements that have been performed parallel to this thesis.

description: The Belle experiment located at Tsukuba (Japan) was designed to ingestive CP violations during quark mixing processes. After a decade of successful operation the Belle detector is going to be upgraded. The upgrade includes an increase of luminosity from 2.11×10 (34) to about 8×10 (35) cm (-2)×s (-1). In order to cope with a 40 t detector (VXD) has been redesigned. The inner part of the VXD consists of two layers of silicon pixel detectors (PXD). Together with the silicon vertex detector (SVD) comprising of four layers of double sided silicon strip detectors (DSSD), the new BELLE II VXD will be able to perform high precision vertex measurements. The most time consuming task of this work was to continue the development of the control software (TuxDAQ) and the design of an online data quality monitoring application (TuxOA) for the SVD system. Both applications has been successfully tested during a beam test at DESY, Germany. Parts of both software systems will be implemented into the future SVD slow control system. The DESY beam test was the first integration test of SVD and PXD subsystems. During the measurements, several noise problems occurred. The impact of the noisy data and the effects on the analysis are discussed in this work. During the beam test at DESY the data was taken from four rectangular DSSDs at several temperatures. The DSSDs are samples taken from the barrel part of each layer of the SVD. The results were evaluated with TuxOA

description: Sebbene il concetto di un livello generale dei prezzi è di qualche utilità limitata a studi puramente statistici e descrittivi , è pericoloso e ingannevole nel campo delle analisi teoriche che mirano a spiegare variazioni di prezzo . Qualsiasi analisi fruttuosa deve distinguere tra i vari tipi di mercati e merci in quanto, nel breve e lungo termine, i meccanismi di formazione dei prezzi e variazione dipendono dagli stessi. In questo lavoro , l'autore dedica particolare attenzione alla dicotomia tra materie prime e merci . Un'altra dicotomia è introdotta con riferimento al mercato del lavoro . La base logica per la doppia dicotomia è data dal grado di flessibilità , rispetto alla domanda , di prezzi e redditi . Although the concept of a general price level is of some limited use in purely statistical and descriptive studies, it is dangerous and deceptive in the field of theoretical analyses which aim at explaining price variations. Any fruitful analysis must distinguish between various types of markets and goods since, in the short and long run, the mechanisms of price formation and variation are dependent on such. In this work, the author devotes special attention to the dichotomy of raw materials and manufactures, a regards goods. Another dichotomy is introduced with reference to the labour market. The logical basis for the double dichotomy is given by the degree of flexibility, in relation to demand, of prices and earnings. JEL: E31

description: L' articolo esamina il funzionamento del sistema finanziario attuale, segnalando la sua funzione più importante , vale a dire l'offerta di liquidità e il suo impatto sulla vasta gamma di variabili finanziarie internazionali. Liquidità e rischio sono concetti strettamente correlati. Come Keynes e Hicks hanno insegnato , una definizione significativa di liquidità non può essere data senza fare riferimento al rischio. L'autore fornisce alcune considerazioni per aiutare a far luce sulle azioni politiche che potrebbero essere necessarie per mitigare i problemi e le difficoltà connesse con l'attuale impostazione monetaria internazionale . The article looks at how the present financial system works, signalling out its most crucial function, namely the provision of liquidity and its impact on the broad spectrum of international financial variables. Liquidity and risk are closely interrelated concepts. As Keynes and Hicks taught, a meaningful definition of liquidity cannot be given without reference to risk itself. The author provides some considerations to help shed light on the policy actions that may be required to mitigate the problems and difficulties associated with the current international monetary setting.

Tuttavia, i dati relativi interni ed esterni relativi ai beni di investimento diretto in cinque paesi oltre questo periodo di 10 anni rivelano alcuni spunti interessanti This note suggests that patterns of international direct investment in manufacturing industry not only tend to follow those of commodity trade, but that, over the years 1965-1975, the intra-industry component of such investment had tended to increase. However, there are only a few countries in the world which are both substantial inward and outward direct investors. Nevertheless, data on outward and inward direct investment assets in five countries over this 10 year period reveal some interesting insights. JEL: F21

description: The no-boundary proposal is a theory of the initial conditions of the universe formulated in semi-classical gravity, and relying on the existence of regular (complex) solutions of the equations of motion. We show by explicit computation that regular no-boundary solutions are modified, but not destroyed, upon inclusion of expected quantum gravity corrections that involve higher powers of the Riemann tensor as well as covariant derivatives thereof. We illustrate our results with examples drawn from string theory. Our findings provide a crucial self-consistency test of the no-boundary framework.

Altitude Effect in Cherenkov Light Flashes of Low Energy Gamma-ray-induced Atmospheric Showers

description: At present the ground-based Very High Energy (VHE) gamma-ray astronomy is racing to complete construction of a number of modern gamma-ray detectors, i.e. CANGAROO III, MAGIC, H.E.S.S., and VERITAS. They should be fully operational in a year's time. After much debate, the further development of this gamma-ray astronomy in the foreseeable future must be widely anticipated to proceed with the designing and building of a new instrumentation, which is primarily intended for the further drastic reduction of the energy threshold in gamma-ray observations down to about 10 GeV. On the ground one can hardly reach such low energy thresholds without considerably larger, up to 30 m diameter, optical telescopes, which might be able to collect sufficient amount of Cherenkov light from the atmospheric gamma-ray showers of that low energy. If not taken off the ground entirely (like GLAST), then it seems to be profitable to mount future low energy Cherenkov telescopes at higher altitudes in the atmosphere in order that they will be able to detect substantially more unabsorbed Cherenkov light from a shower. There are a few sites up on the high mountains of roughly 5 km height worldwide, which can be used for such a venture. However, one has to remember that actual time profile, and in particular a two-dimensional distribution (image) of Cherenkov light flash from atmospheric gamma-ray showers, undergo a rapid change after an increase in the observational level. This paper briefly describes the results of a topological analysis of Cherenkov light images calculated at both conventional and desirable altitudes of 2.2 and 5 km above the sea, respectively. A discussion on major upgrades of image topology at high altitude is also given.

description: We study the impact of using fluid-structure interactions (FSI) to simulate blood flow in a large stenosed artery. We compare typical flow configurations using Navier-Stokes in a rigid geometry setting to a fully coupled FSI model. The relevance of vascular elasticity is investigated with respect to several questions of clinical importance. Namely, we study the effect of using FSI on the wall shear stress distribution, on the Fractional Flow Reserve and on the damping effect of a stenosis on the pressure amplitude during the pulsatory cycle. The coupled problem is described in a monolithic variational formulation based on Arbitrary Lagrangian Eulerian (ALE) coordinates. For comparison, we perform pure Navier-Stokes simulations on a prestressed geometry to give a good matching of both configurations. A series of numerical simulations that cover important hemodynamical factors are presented and discussed.

description: Diese Arbeit gibt eine kurze Zusammenfassung der wichtigsten Konvergenzbegriffe der Maßtheorie. Dabei werden im ersten Teil die Konvergenz fast überall, die fast gleichmäßige Konvergenz, die Konvergenz nach Maß bzw. lokal nach Maß und die Konvergenz der p-fach integrierbaren Funktionen untersucht und verglichen. Im zweiten Teil der Arbeit wird die schwache Konvergenz in der möglichst allgemeinen Umgebung topologischer Räume untersucht, an die - im Gegensatz zur meisten Literatur - keine weiteren Anforderungen gestellt werden. Dazu werden zunächst Baire-, Borel- und Radonmaße eingeführt und deren wichtigsten Eigenschaften gezeigt und verglichen. Dies beinhaltet unter anderem die Fortsetzung von additiven regulären Mengenfunktionen zu Radon- bzw. zu tau-additiven Maßen auf der gesamten Borel'schen Sigma-Algebra. Weiters wird gezeigt, in welchem Zusammenhang lineare Funktionale auf dem Raum der stetigen und beschränkten Funktionen mit Baire-, Radon bzw. tau-additiven Maßen stehen. Dazu wird das Daniell-Integral verwendet, das in dieser Arbeit ebenfalls konstruiert wird. Außerdem wird demonstiert, dass durch die Verwendung des Daniell-Integrals der Darstellungssatz von Riesz als Nebenprodukt in sehr kurzer und kompakter Form bewiesen werden kann.
description: This diploma thesis gives a short summary of the main modes of convergence in measure theory. These include in the first part convergence almost everywhere, almost uniform convergence, convergence in measure and locally in measure and the convergence in Lebesgue-spaces. The second part deals with measures on topological spaces, where the weak convergence of nets of Baire-measures is examined. There is no further assumption about the underlying topological space. To do so, first Baire-, Borel- and Radon measures are introduced and their basic properties are shown and compared. Also, constructing and using the Daniell-Integral, the relationship of linear functionals to these measures is examined.

Sie ermöglichen die Handlungsplanung, -überwachung und -kontrolle. Wie das Gehirn lernt und welche Aspekte das Lernen zudem beeinflussen, werden aus neurowissenschaftlicher, psychologischer sowie pädagogischer Sichtweise erläutert. Im Theorieteil werden zunächst die Funktionsweise des Gehirns sowie die Entwicklung und Bedeutung der Exekutiven Funktionen genauer beschrieben. Die vorliegende Masterarbeit zielt darauf ab, das Training mit aufmerksamkeitsgestörten Kindern und deren Wirksamkeit auf Exekutive Funktionen hin zu untersuchen. An diesem Training haben sechs Kinder mit Lernschwierigkeiten aus der 2.Klasse teilgenommen. Die Forschungsarbeit beruht hauptsächlich auf qualitativen Methoden in Form einer Einzelfallstudie unter Einbezug quantitativer Screeningverfahren. Die erhobenen Daten zeigen, dass eine deutliche Verbesserung der Aufmerksamkeit möglich ist. Unter bestimmten Voraussetzungen können auch positive Effekte auf die Exekutiven Funktionen erzielt werden. Faktoren, die die Exekutiven Funktionen und deren Transfer fördern bzw. hemmen, werden aufgezeigt. Einige Methoden und Techniken stellen sich als besonders wirksam heraus, sind universell einsetzbar und für den weiteren Einsatz in der Schulpraxis besonders geeignet.

description: We revisit the cellular dynamical mean-field theory (CDMFT) for the single band Hubbard model on the square lattice at half filling, reaching real-space cluster sizes of up to 9 x 9 sites. Using benchmarks against direct lattice diagrammatic Monte Carlo at high temperature, we show that the self-energy obtained from a cluster center focused extrapolation converges faster with the cluster size than the periodization schemes previously introduced in the literature. The same benchmark also shows that the cluster spin susceptibility can be extrapolated to the exact result at large cluster size, even though its spatial extension is larger than the cluster size.

description: Accurate measuring the location and orientation of individual particles in a beam monitoring system is of particular interest to researchers in multiple disciplines. Among feasible methods, gaseous drift chambers with hybrid pixel sensors have the great potential to realize long-term stable measurement with considerable precision. In this paper, we introduce deep learning to analyze patterns in the beam projection image to facilitate three-dimensional reconstruction of particle tracks. We propose an end-to-end neural network based on segmentation and fitting for feature extraction and regression. Two segmentation branches, named binary segmentation and semantic segmentation, perform initial track determination and pixel-track association. Then pixels are assigned to multiple tracks, and a weighted least squares fitting is implemented with full back-propagation. Besides, we introduce a center-angle measure to judge the precision of location and orientation by combining two separate factors. The initial position resolution achieves 8.8 $μm$ for the single track and 11.4 $μm$ (15.2 $μm$) for the 1-3 tracks (1-5 tracks), and the angle resolution achieves 0.15$^{\circ}$ and 0.21$^{\circ}$ (0.29$^{\circ}$) respectively. These results show a significant improvement in accuracy and multi-track compatibility compared to traditional methods.

description: Il tema degli effetti dei controlli diretti sul credito bancario ha assunto sempre maggiore rilevanza nel corso del tempo , gli interventi si sono progressivamente evoluti dall essere uno strumento temporaneo di politica monetaria ad un elemento stabile del quadro istituzionale degli ultimi anni . Mentre i vincoli al portfolio di investimenti sono stati notevolmente facilitati dal 1978 , i limiti sui prestiti bancari sono aumentati in importanza come uno degli strumenti per la regolamentazione del credito totale interno . Il presente documento individua i principali effetti collaterali di limiti di credito e fornisce i dati necessari per valutare la loro dimensione effettiva . E poi illustra come alcuni paesi stranieri che esercitano il controllo diretto sul credito hanno introdotto politiche progettate per ridurre i loro inconvenienti .. The theme of the effects of direct controls on bank lending has taken on increasing relevance over time, as interventions have gradually evolved from being a temporary instrument of monetary policy to a stable element of the institutional framework of recent years. While portfolio constraints have been significantly eased since 1978, limits on bank loans have increased in importance as one of the tools for regulating total domestic credit. The present paper identifies the main side effects of credit limits and provides the necessary data to assess their effective size. It then illustrates how some foreign countries who exercise direct control over credit have introduced policies designed to mitigate their drawbacks. JEL: E51, E52, G21

Elastic moduli fluctuations predict wave attenuation rates in glasses

description: The disorder-induced attenuation of elastic waves is central to the universal low-temperature properties of glasses. Recent literature offers conflicting views on both the scaling of the wave attenuation rate $Γ(ω)$ in the low-frequency limit ($ω\!\to\!0$), and on its dependence on glass history and properties. A theoretical framework -- termed Fluctuating Elasticity Theory (FET) -- predicts low-frequency Rayleigh scattering scaling in $d$ spatial dimensions, $Γ(ω)\!\sim\!γ\,ω^{d+1}$, where $γ\!=\!γ(V_{\rm c})$ quantifies the coarse-grained spatial fluctuations of elastic moduli, involving a correlation volume $V_{\rm c}$ that remains debated. Here, using extensive computer simulations, we show that $Γ(ω)\!\sim\!γ\,ω^3$ is asymptotically satisfied in two dimensions ($d\!=\!2$) once $γ$ is interpreted in terms of ensemble -- rather than spatial -- averages, where $V_{\rm c}$ is replaced by the system size. In so doing, we also establish that the finite-size ensemble-statistics of elastic moduli is anomalous and related to the universal $ω^4$ density of states of soft quasilocalized modes. These results not only strongly support FET, but also constitute a strict benchmark for the statistics produced by coarse-graining approaches to the spatial distribution of elastic moduli.

description: Magneto-optical imaging of thick stress-free lead samples reveals two distinct topologies of the intermediate state. Flux tubes are formed upon magnetic field penetration (closed topology) and laminar patterns appear upon flux exit (open topology). Two-dimensional distributions of shielding currents were obtained by applying an efficient inversion scheme. Quantitative analysis of the magnetic induction distribution and correlation with magnetization measurements indicate that observed topological differences between the two phases are responsible for experimentally observable magnetic hysteresis.

title: Mapped Tent Pitching method for hyperbolic conservation laws
Creators: name: Wintersteiger, Christoph
Publisher: name: TU Wien
Year: 2015
Subjects: subject: space-time methods
subject: Discontinuous Galerkin
subject: entropy-viscosity

description: This thesis introduces a novel discretization technique for solving hyperbolic conservation laws, called Mapped Tent Pitching (MTP) scheme. A tent pitching algorithm creates space-time domains, called tents, by vertically erecting canopies over spatial vertex patches. The structure of such a tent pitched space-time mesh is exploited by the MTP scheme to map these tents to a reference domain with a space-time tensor product structure. These domains are spatially discretized with a high order discontinuous Galerkin method, combined with a time stepping method. To obtain a robust method an entropy viscosity regularization is applied. This MTP scheme is implemented as part of this thesis based on the finite element library Netgen/NGSolve and tested with challenging problems like the Euler equations.
Elasticity, community & hope: understandings from participatory theatre performance
Creators: name: Smith, Anne Louise
Publisher: name: University of British Columbia
Year: 2011

description: This performative inquiry begins with a research project I conducted in the summer of 2004, a six week “participatory theatre laboratory’ with eight undergraduate students in the Theatre Program of the Department of Theatre, Film & Creative Writing, at the University of British Columbia. Integral to the laboratory were six participatory theatre performances with day camps in the Greater Vancouver area. Seven youth leader participants from three of these performances and two student actors were interviewed six to eight weeks later to discover what they remembered of their experience with ParticipAction Theatre. Their responses cover a wide range of interests, focusing predominantly on the value of involvement. My conceptual explorations encompass the late twentieth century movement towards audience involvement in theatre performance, theatre for education and social change, performance studies, and the relation of the artist, as mystic, to the community. Community is a contested term: I borrow from the Amerindian1 understanding of community to ground my own interpretation. I perform this inquiry as an ongoing journey of discovery, using stories from the Tricksters’ Theatre tours, my initial work in participatory performance, to propel the journey between stopping places of reflection. Elasticity, community, and hope, are three concepts that have risen through my exploration of the experience of participatory theatre. Elasticity bespeaks the dynamic of inter-relationships between people when they perform together. I identify what participants have reported as a ‘feeling of community’ when performing together to be an “excess” of performance” (Kershaw, 1 999, p. 64). This dissertation explores how participatory theatre performance can generate these “excesses” and theorizes an elastic connection between performing together and feeling a sense of community. The value of feeling community is that it may reveal an emergent culture of hope in situations where people perform together. 1 I choose to use the designation “Amerindian” following Olive P. Dickason’s rational that it is more specific than “Native” “Indian”, or “Aboriginal” (Dickason, 2002, p. xiv-xv).

In questa nota, l'autore mette in discussione il modello di Thirlwall, mostrando che, insieme con l'evidenza empirica non è in grado di discriminare tra la domanda e l'offerta approcci alla crescita orientata. In a recent article A.P. Thirlwall derived what he termed a “fundamental law” which he argued explains the disparate post-war growth rates of advanced countries. In this note, the author takes issue with Thirlwall’s model, showing that together with the empirical evidence it is not capable of discriminating between the demand and the supply orientated approaches to growth.

description: We present a calculation of the next-to-leading order QCD corrections for the scattering of Dark Matter particles off nucleons in the framework of simplified models with s- and t-channel mediators. These results are matched to the Wilson coefficients and operators of an effective field theory that is generally used for the presentation of experimental results on spin-independent and spin-dependent direct detection rates. Detailed phenomenological studies illustrate the complementary reach of collider searches for Dark Matter and the direct detection experiments CRESST and XENON. In the case of cancellation effects in the tree-level contributions, one-loop corrections can have a particularly large impact on exclusion limits in the case of combined s+t-channel models.
