AI-appar Vad skulle du vilja fråga Julius Caesar, Virginia Woolf, Adolf Hitler? På senare tid har flera AI- tjänster dykt upp som tillåter användaren att samtala med avlidna kändisar. Så inleds ett nytt kapitel i den både uråldriga och fåfänga drömmen om att kommunicera med de döda.

In this article we compute lossy Bloch waves in two-dimensional photonic crystals with dispersion and material loss. For given frequencies these waves are determined from non-linear eigenvalue problems in the wave vector. We applied two numerical methods to a demanding test case, a photonic crystal with embedded quantum dots that exhibits very strong and anamolous dispersion. The first method is b

Meshless methods are a promising new field in computational electromagnetics. Instead of relying on an explicit mesh topology, a numerical solution is computed on an unstructured set of collocation nodes. This allows to model fine geometrical details with high accuracy and facilitates the adaptation of node distributions for optimization or refinement purposes. The radial point interpolation metho

When and where it is convenient to start working on raising awareness on gender issues? Our answer is that high school is definitely a good start, mainly if we think that outreach activities can have a role in the transition to an environment for learning, teaching and researching in physics that is equally attractive and supportive to all genders, at each stage of their education and career path.

Inherited resistance to activated protein C (APC-resistance) and protein S deficiency are associated with functional impairment of the protein C anticoagulant system, resulting in lifelong hypercoagulability andincreased risk of thrombosis. APC-resistance is the most common genetic cause of thrombosis being present in 20% to 60% of thrombosis patients.A linkage study was performed in a large throm

For two-component composites, we address the inverse problem of estimating the structural parameters and decrease measurement errors in bulk property measurements. A measurement of the effective permittivity at one frequency gives microstructural information about the composite that is used in cross-property bounds to estimate the effective permittivity at other frequencies. We use this informatio

Rörelsekvalité är en faktor som anses vara viktig att utvärdera hos patienter med främre korsbandsskada. Däremot har det inte varit helt klarlagt hur rörelsekvaliteten ska utvärderas. Denna avhandling utvärderar postural orientering som ett kliniskt mått på rörelsekvalitet

Alteration in postural orientation (i.e., the ability to align body segments in relation to each other) can occur due to pain or injury and is suggested to be a risk factor for traumatic knee injuries and early onset and progression of knee osteoarthritis. However, clinical and biomechanical assessment of postural orientation is time-consuming, thus new and faster methods are needed in order to be

BACKGROUND: Cryptogenic stroke is a heterogeneous condition, with a wide spectrum of possible underlying causes for which the optimal secondary prevention may differ substantially. Attempting a correct etiological diagnosis to reduce the stroke recurrence should be the fundamental goal of modern stroke management.METHODS: Prospective observational international multicenter study of cryptogenic str

Introduction: Over the past two decades, there has been a shift from concealing diagnoses of sex development from impacted people to the broad principle of age-appropriate disclosure. This change is consistent with children’s rights and with general shifts towards giving children medical information and involving patients in medical decision-making. The present paper examines how health profession

The purpose of this project was to study the impact of three different protein systems on the physicochemical stability of alcohol-containing emulsions. Egg yolk plasma, sodium caseinate and whey protein isolate (WPI) were used for that purpose. For this reason, the solubility of the three protein systems in the presence of different levels of ethanol was first determined. Oil–in–water emulsions (

A wide variety of photoinduced electronic coherences are shown to be robust with respect to dephasing in ensembles of quasi-homodimers assembled with sub-nm ligands from colloidal 3 nm CdSe quantum dots (QDs) with controlled 9% size dispersion, both in solution and in solid-state. Coherence periods ranging from 40 to 300 fs are consistently characterized by multidimensional electronic spectroscopy

Risk matrices are tables with rows representing consequences, and columns representing frequencies. The risk matrix is considered a simple and convenient tool for visualizing risk. However, it has faced critique from the scientific community. Though risk matrices are extensively applied in practice for visualizing results from coarse risk analyses, there is limited research regarding guidance on i

The Covid-19 pandemic has changed our lives. The first and unexpected lockdown in Italy has seriously upset people daily routine, working organisation, socialisation and interactions with colleagues and relatives. To overcome the physical isolation and collect impressions, the “How are you?” online questionnaire was created and shared as a conversation among friends. Text mining techniques have be
