Central spin decoherence caused by nuclear spin baths is often a critical issue in various quantum computing schemes, and it has also been used for sensing single-nuclear spins. Recent theoretical studies suggest that central spin decoherence can act as a probe of many-body physics in spin baths; however, identification and detection of many-body correlations of nuclear spins in nanoscale syste...

The biosorption potential of three fungal waste-biomasses (Acremonium strictum, Acremonium sp. and Penicillium sp.) from pharmaceutical companies was compared with that of a selected biomass (Cunninghamella elegans), already proven to be very effective in dye biosorption. Among the waste-biomasses, A. strictum was the most efficient (decolorization percentage up to 90% within 30 min) with regar...

One hundred and three patients with an acute first episode of posterior anal fissure were randomised to receive a three week trial of lignocaine ointment (n = 33) versus hydrocortisone ointment (n = 35) or warm sitz baths combined with an intake of unprocessed bran (n =35). Seven patients were withdrawn owing to failure to adhere to the trial protocol. After one and two weeks of treatment sympt...

The performance characteristics of a heat rectifier and a heat pump are studied in a non-Markovian framework. The device is constructed from a molecule connected to a hot and cold reservoir. The heat baths are modelled using the stochastic surrogate Hamiltonian method. The molecule is modelled by an asymmetric double-well potential. Each well is semi-locally connected to a heat bath composed of...

Dr Thomas Stockmann, the protagonist of Ibsen's play, An Enemy of the People, discovers a serious health threat in the Baths of his Norwegian town. The Baths have been marketed as a health resort to lure visitors. Dr Stockmann alerts officials about the problem and assumes that they will close the Baths until it is corrected. He is met with fierce resistance, however. His brother, the town's ma...

BACKGROUND Despite advances in the treatment of depression, one-third of depressed patients fail to respond to conventional antidepressant medication. There is a need for more effective treatments with fewer side effects. The primary aim of this study was to determine whether hyperthermic baths reduce depressive symptoms in adults with depressive disorder. METHODS Randomized, two-arm placebo-...

We study entropy production in nanoscale devices, which are coupled to finite heat baths. This situation is of growing experimental relevance, but most theoretical approaches rely on a formulation the second law valid only for infinite fix this problem by pointing out that already Clausius' paper from 1865 contains an adequate baths, can be also rigorously derived microscopic quantum descriptio...
