Adolph von Menzel (1815–1905), one of the greatest German realistic painters of the nineteenth Century (1), painted his right foot from normal perspective with the great toe extended (Figure 1B). The other toes seem to be relaxed. There are no suggestions of foot deformity like pes cavus. Menzel finished that painting, oil on wood panel, in 1876 (1). He gave no official explanation, why he had ...

The effect of chaotic bath dynamics on the decoherence of a quantum system is examined for the vibrational degrees of freedom of a diatomic molecule in a realistic, constant temperature collisional bath. As an example, the specific case of I(2) in liquid xenon is examined as a function of temperature, and the results compared with an integrable xenon bath. A crossover in behavior is found: The ...

Understanding and mitigating decoherence is a key challenge for quantum science and technology. The main source of decoherence for solid-state spin systems is the uncontrolled spin bath environment. Here, we demonstrate quantum control of a mesoscopic spin bath in diamond at room temperature that is composed of electron spins of substitutional nitrogen impurities. The resulting spin bath dynami...

By exact numerical and master equation approaches, we show that a central spin1/2 can be configured to probe internal bath dynamics. System-bath interactions cause Rabi oscillations in the detector and periodic behavior of fidelity. This period is highly sensitive to the strength of the bath self-interactions, and can be used to calculate the intra-bath coupling.

International Centre for Trade and Sustainable Development The use of genetic resources and associated traditional knowledge (ATK) has been characterized by lack of regulation and unfair benefit sharing. This picture began to change only in 1993, when the Convention on Biological Diversity (CBD) came into force recognizing national sovereignty over genetic resources and the need for benefit sha...

BACKGROUND For bedridden patients unable to perform personal hygiene measures because of acute illness or chronic debilitation, the bed bath, with either the traditional basin or, more recently, disposable baths, has long been a measure for improving hygiene and costs. OBJECTIVE To compare the traditional basin bed bath with a prepackaged disposable bed bath in terms of 4 outcomes: time and q...

A tractable production-externality-based circular city model in which both firms and workers choose location as well as intensity of land use is presented. The equilibrium structure of the city has either (i) no commuting (“mixed-use” form) or (ii) a central business district (CBD) of positive radius and a surrounding residential ring. Regardless of which form prevails, the intra-city variation...
