Understanding the formation of topological defects in ferroelectric materials can provide access to their unusual physics, invaluable for possible applications of domain engineering in nanoelectronics. The present study shows the spontaneous formation of center-type topological defects in lead zirconate titanate (PZT) films, characterized by a strong in-plane radial electromechanical response on r

We experimentally investigate the properties of one-dimensional quantum rings that form near the surface of nanowire quantum dots. In agreement with theoretical predictions, we observe the appearance of forbidden gaps in the evolution of states in a magnetic field as the symmetry of a quantum ring is reduced. For a twofold symmetry, our experiments confirm that orbital states are grouped pairwise.

The goal of paleoproteomics is to characterize proteins from specimens that have been subjected to the degrading and obscuring effects of time, thus obtaining biological information about tissues or organisms both unobservable in the present and unobtainable through morphological study. Although the description of sequences from Tyrannosaurus rex and Brachylophosaurus canadensis suggested that pro

We have performed a systematic study for the nuclear structure of superheavy nuclei with a special emphasis on the nuclei with possible central depletion of proton and neutron density in the mass region A â 300 using the Relativistic Hartree-Bogoliubov (RHB) framework. It has been observed that in the case of neutron density distribution, the occurrence of central depletion is related to the occup

Public acceptability is important for sustainable land use zoning policy to be successfully implemented. This study examined the effectiveness of tailoring messages with cultural worldviews to induce positive attitudes and improve public acceptability of sustainable land use zoning policy in a post-conflict setting. A total of 538 participants were randomly divided into three groups. Two were trea

Members of the Actinobacteria, including mycobacteria and streptomycetes, exhibit a distinctive mode of polar growth, with cell wall synthesis occurring in zones at cell poles and directed by the essential cell polarity determinant DivIVA. Streptomyces coelicolor modulates polar growth via the Ser/Thr protein kinase AfsK, which phosphorylates DivIVA. Here, we show that the phosphoprotein phosphata

Superconducting devices, based on the Cooper pairing of electrons, play an important role in existing and emergent technologies, ranging from radiation detectors1,2 to quantum computers3. Their performance is limited by spurious quasiparticle excitations formed from broken Cooper pairs4–12. Efforts to achieve ultra-low quasiparticle densities have reached time-averaged numbers of excitations on th

In 2018, NATO carried out Trident Juncture, its largest military exercise since the Cold War. The event was promoted on social media featuring Lasse Matberg as “the face of NATO”. Matberg is an Instagram influencer, model and lieutenant in the Royal Norwegian Navy, with an impressive physique and Viking looks. He frequently appears on NATOs social media accounts and lends his own platform to share

Governmental policies and business models are considered key elements for a transition to a circular economy. In current literature, there is a lack of understanding on how these two elements interact and how this understanding is used to accelerate the realisation of a circular economy. We shed light on this issue by conducting a systematic review of the literature in combination with a literatur

Whereas bureaucracy and vertical pyramid-like organization structures have been criticized for decades, most organizations still work as complex hybrids rather than full-fledged post-bureaucratic organizations. The hierarchical decision-structure and the accompanying top-down oriented vertical communication chain is still highly alive in conjunction with an aspiration for post-bureaucratic princip

Research in the field of socio-economic analysis of antibiotic resistance is limited and needs to be developed. Such analyzes include calculating in-creased care costs and societal costs. According to the Swedish Public Health Authority’s calculations of future costs for antibiotic resistance, the number of cases detected in Sweden with notifiable resistance types will quadruple from 15.500 cases

The Swedish government is at present investing heavily in making Sweden competitive in AI (Artificial Intelligence). As a part of that effort, Lund University has been commissioned with providing a series of MOOCs (Massive Open Online Courses) on different topics regarding AI, including several topics dealing with Humans and AI. As a comprehensive university, Lund University has an advantage in be

Med stöd av diskursanalys belyser artikeln hur en sjukhusledning, medsjukhuschef, verksamhetschefer och smittskyddsläkare, hanterar antibiotikaresistenspå sjukhus. En framträdande diskurs handlar om att påverkabeteendet hos personal och patienter för att skapa renhet och engageramedarbetarna. Fraser som ”Rena händer är viktigast.” och ”Tvätta dina händer.”ingår i diskursen. Den andra, rumsliga dis

Empirical evidences in the library and the historian’s search tools: Union catalogues, bibliographies, databases, and the omission of Melchior Hofmann’s works from the Swedish national bibliographyThe article considers the connection between historians’ interpretations of the past and the search tools (catalogues, bibliographies, and databases) they use to access empirical source material in libra

Background: Strong evidence suggests that suicide attempters who repeatsuicide (re-attempters) may differ from those with a single attempt (singleattempters) in various clinical and sociodemographic factors. Furthermore, thereis some evidence that re-attempters may be characterized by higher levels ofneuroticism, a well-known risk factor for completed suicide compared to singleattempters.Purpose:

Background and purpose - Vitamin E infused highly cross-linked polyethylene (VEPE) was introduced in order to enhance oxidative resistance in highly cross-linked polyethylene cups in total hip arthroplasty (THA). We have, with a follow-up of 5 years, evaluated wear characteristics of 2 identically designed cemented cups with the only difference being the material, VEPE or ultra-high molecular weig
