The impact of visual working memory capacity on the filtering efficiency of emotional face distractors.

2018

Emotional faces can serve as distractors for visual working memory (VWM) tasks. An event-related potential called contralateral delay activity (CDA) can measure the filtering efficiency of face distractors. Previous studies have investigated the influence of VWM capacity on filtering efficiency of simple neutral distractors but not of face distractors. We measured the CDA indicative of emotional face filtering during a VWM task related to facial identity. VWM capacity was measured in a separate colour change detection task, and participants were divided to high- and low-capacity groups. The high-capacity group was able to filter out distractors similarly irrespective of its facial emotion. …

Superconductivity near a magnetic domain wall

2018

We study the equilibrium properties of a ferromagnetic insulator/superconductor structure near a magnetic domain wall. We show how the domain wall size is affected by the superconductivity in such structures. Moreover, we calculate several physical quantities altered due to the magnetic domain wall, such as the spin current density and local density of states, as well as the resulting tunneling conductance into a structure with a magnetic domain wall.

MoMo: enabling hybrid museums

2005

Present-day museums are not mere passive institutions for the preservation of a society's cultural heritage. They have become instead learning environments, research centres and even tourist attractions. The paper introduces the notion of a hybrid museum (HM) in which wireless personal digital devices (PDAs) are used to tailor digital contents to the visitor to enrich both the learning and entertainment experience. The paper describes a fully functional hybrid museum infrastructure (MoMo) implemented with the.NET compact framework running on the PocketPC platform. Several research challenges that had to be faced during the implementation of the system such as the exploration of large sets o…

Code Contracts ja ComTest-yksikkötestausgenerointi .NET-kielissä

2015

Opetuksen tehostamiseen suunnattu työkalu ComTest osaa luoda yksikkötestejä koodin kommentteihin kirjoitettujen ohjeiden perusteella. Sopimuspohjaisessa suunnittelussa olion metodeille asetetaan ehtoja, joiden on oltava voimassa ennen operaation suorittamista tai sen jälkeen. Tällaiset ehdot voidaan automaattisesti kirjoittaa osaksi koodin kommentteja. Code Contracts on laajennos .NET-kieliin, jonka avulla sopimuspohjainen suunnittelu saadaan osaksi sovelluskehitystä. Tutkimuksessa selvitetään, miten ComTest ja Code Contracts liittyvät toisiinsa. ComTest, a tool mainly directed to make teaching more efficient, is able to create Unit Tests based on directions written in the code comments. In…

Due note etimologiche circostanziali circa il Ms.II.D.54 (BNN) attribuito a Baffi

2019

Within the investigations on the attribution of some manuscripts to the famous philologist P. Baffi and now kept at the National Library of Naples (BNN), this brief contribution investigates in detail some of the passages contained in Ms.II.D.54 (f. 234r et f. 325r), in order to understand its meaning and to evaluate and validate its attributing hypotheses.

Cave bear occupation in Schwabenreith Cave, Austria, during the early last glacial: constraints from 230 Th/U‐dated speleothems

2019

The cave bear was a prominent member of the Upper Pleistocene fauna in Eurasia. While breakthroughs were recently achieved with respect to its phylogeny using ancient DNA techniques, it is still challenging to date cave bear fossils beyond the radiocarbon age range. Without an accurate and precise chronological framework, however, key questions regarding the palaeoecology cannot be addressed, such as the extent to which large climate swings during the last glacial affected the habitat and possibly even conditioned the final extinction of this mammal. Key to constraining the age of cave bear fossils older than the lower limit of radiocarbon dating is to date interlayered speleothems using 23…

The impact of quantitative easing on UK bank lending: Why banks do not lend to businesses?

2021

Abstract The growing proportion of UK bank lending to the financial sector reached a peak in 2007 just before the onset of the Global Financial Crisis (GFC). This marks a trend in the dwindling amount of bank lending to private sector non-financial corporations (PNFCs), which was exacerbated with the Great Recession. Many central banks aimed to revive bank lending with quantitative easing (QE) and unconventional monetary policy. We propose an agent based computational economics (ACE) model which combines the main factors in the economic environment of QE and Basel regulatory framework to analyse why UK banks do not prioritize lending to non-financial businesses. The lower bond yields caused…

The 3D structure of fabric and its relationship to liquid and vapor transport

2004

Polymeric carrier fabrics are commonly used in many industrial processes including manufacture of paper and board. Apart from acting as a carrier for the compressible porous material during the manufacturing process, the synthetic woven fabrics comprising mainly of poly ethylene terypthalate (PET) yarns, impart valuable product attributes, i.e. softness, bulk, absorbency, etc. in consumer products. The three-dimensional structure of the fabrics plays a critical role in deciding the manufacturing and energy efficiency as well as product end-use properties. X-ray micro computed tomography (X-CT) provides a non-intrusive technique to visualize and analyze the three-dimensional structure of por…

Use of Density Functional Based Tight Binding Methods in Vibrational Circular Dichroism.

2018

Vibrational circular dichroism (VCD) is a spectroscopic technique used to resolve the absolute configuration of chiral systems. Obtaining a theoretical VCD spectrum requires computing atomic polar and axial tensors on top of the computationally demanding construction of the force constant matrix. In this study we evaluated a VCD model in which all necessary quantities are obtained with density functional based tight binding (DFTB) theory. The analyzed DFTB parametrizations fail at providing accurate vibrational frequencies and electric dipole gradients but yield reasonable normal modes at a fraction of the computational cost of density functional theory (DFT). Thus, by applying DFTB in comp…
