One of the leading ideas for the beginning of the Universe is the Hartle-Hawking ‘No-Boundary Proposal.’ Since the Cobordism Conjecture claims that any spacetime allows for a dynamical boundary, we suggest that one may equally well consider a ‘

Abstract We study bubble of nothing decays and their reverse processes, the creation of vacua through ‘bubbles of something’, in models of the Universe based on string theory. From the four-dimensional perspective, the corresponding gravitational

According to the ‘Cosmological Central Dogma’, de Sitter space can be viewed as a quantum mechanical system with a finite number of degrees of freedom, set by the horizon area. We use this assumption together with the Wheeler-DeWitt (WDW) equatio

Vasopressin, endothelin and adrenomedullin are vasoactive peptides that regulate vascular tone and might play a role in hypertensive diseases. Recently, laboratory assays have been developed to measure stable fragments of vasopressin, endothelin and

Functional decline in older adults can lead to an increased need of assistance or even moving to a nursing home. Utilising home automation, power and wearable sensors, the system developed by the author continuously keeps track of the functional stat

BACKGROUND: In hemodialysis patients, elevated plasma troponin concentrations are a common finding that has even increased with the advent of newly developed sensitive assays. However, the interpretation and relevance of this is still under debate. M

Vektorräume dienen als Anschauungsraum für viele Aspekte unserer Wirklichkeit. Während additive Ausprägungen abstrakter Vektorräume zum Curriculum der mathematischen Ausbildung gehören, sind nicht-additive Ausprägungen eher unbekannt. Dabei k
Eltern nehmen im Zusammenhang mit WhatsApp, YouTube und Co. meist nur die negativen Schlagzeilen wahr und möchten ihr Kind am liebsten davon fernhalten. Doch ein Verbot dieser Angebote ist nicht die beste Option, denn das Smartphone ist aus dem Allt

Background/Aims: Serum- and glucocorticoid-inducible kinase 1 (SGK1) stimulates the epithelial sodium channel (ENaC), renal outer medullary K+ channel 1, Na+/K+-ATPase and presumably the Na+-Cl– cotransporter (NCC). SGK1-deficient mice (sgk–/–)
