We derive short-distance constraints for the hadronic light-by-light contribution (HLbL) to the anomalous magnetic moment of the muon in the kinematic region where the three virtual momenta are all large. We include the external soft photon via an external field leading to a well-defined Operator Product Expansion. We establish that the perturbative quark loop gives the leading contribution in a w

This thesis is concerned with spoken dialogue and the dynamic negotiation of meaning in English conversation. It serves two aims, one theoretical and the other practical. The theoretical aim is to further our understanding of the kinds of properties that influence the meaning of constructions in spoken dialogue and the role of underlying socio-cognitive processes. The practical aim is to compile a

The internal microstructure of injection-molded dogbone specimens of talc-filled isotactic polypropylene has been investigated using a home laboratory scanning wide-angle X-ray scattering setup, yielding two-dimensional maps of molecular orientation and ordering for cross-sections parallel and perpendicular to the flow direction with unprecedented details. In addition to demonstrating a high degre

The Learning with Errors problem (LWE) is one of the main candidates for post-quantum cryptography. At Asiacrypt 2017, coded-BKW with sieving, an algorithm combining the Blum-Kalai-Wasserman algorithm (BKW) with lattice sieving techniques, was proposed. In this paper, we improve that algorithm by using different reduction factors in different steps of the sieving part of the algorithm. In the Rege

Removing obstacles to e-commerce in the Single Market and ensuring effectivetaxation in the context of the digital economy has been high on the political agendaboth in the European Union and beyond. Recently the VAT rules on cross-border ecommerce have gone through a thorough modernisation with a package of newprovisions in the EU VAT legislation coming into effect as of 2019 and 2021. Furthermeas

An improved solution of the non-linear and ill-posed inverse problem of electro-cardiography is presented. The hearts activity is modeled by three di®erent equivalent cardiac sources: 1 moving dipole, 2 and 5 fixed location rotating dipoles. For this purpose a three dimensional volume conductor model of the human body is constructed based on a classical anatomic atlas. This is excited by each one

The introduction of high efficiency and multifunctional equipment for road survey increase not only the quality but also the possibility of integration of different source of data to increase the value of the information. The present research work, starting from a common data source, the Automatic Road Analyzer (ARAN) of the University of Catania, shown as data surveyed with ARAN can be used to de

Debate article on how to view the Kalmar Union as a state, and on how to view political-territorial entities in late medieval Europe in general.

Träd+radio är ett hörspel om trädens underjordiska rotsystem, om att lyssna på radio, om den stränga filosofen Simone Weil, om att finna den största njutningen i smärtan, våldet och lydnaden, om att förvandlas till ett träd och om en dröm om undergången.

Large-scale land acquisitions (LSLA) in resource-rich countries came to global attention after the food and financial crises of 2008. Previous research has assessed the magnitude of these land investments in terms of land areas acquired. In this study, we analyze the trends in the evolution of LSLA by framing the latter as virtual land trade network with land transactions occurring between 2000 an

Virtual reality möter scenkonst, spel och installation i ett omslutande verk där det inte finns någon skillnad mellan minne och fiktion. Över 20 medverkande konstnärer tolkar olika drömmar – tillsammans visar de drömmens potential att visa oss en annan värld och föreställa oss förändring.I The Dreambox kan vi göra individuella drömmar till kollektiva minnen. Verket består av flera rum där publiken

Text tonsatt av Cecilia Franke (medlem av Föreningen Svenska Tonsättare), uruppförande i Hellvi kyrka, Gotland. Blandad kör, piano, violin och cello.

HYPOTHESIS: The clinical and physiological features of patients with short segments of columnar-lined esophagus (CLE) with and without intestinal metaplasia (IM) are distinct.DESIGN: Retrospective case series.SETTING: University tertiary referral center.PATIENTS: Sixty-five consecutive patients with a 2-cm or shorter length of endoscopically visible CLE.INTERVENTIONS: The type of CLE and the prese

BACKGROUND: This study evaluates the efficiency and safety of two methods of chest drainage after uncomplicated oesophagectomy.METHODS: A prospective randomized study between active suction drainage and passive chest drainage was carried out in 101 patients who underwent gastric pull-up oesophagectomy.RESULTS: No difference in the prevalence of pneumothorax during treatment was noted between the a

Public transport is an important part of the transition to a more sustainable future. The increasingly market-oriented public transport companies today market themselves with a wealth of messages in multiple channels such as direct mail, websites and apps. This communication is part of the influence that the (potential) traveler is exposed to, yet little research and testing is carried out in orde

This case study on the dark side of communication and place branding explores the Amazon corporation’s highly-publicized competitive search for a city to become their second headquarters (dubbed HQ2). In 2017 Amazon sent an open Request for Proposals (RFP) to cities in North America defining what constitutes an ‘ideal’ headquarters. In addition to offering capital and incentives, Amazon’s ideal ci
