The temperature dependence of the Casimir force between a real metallic plate and a metallic sphere is analyzed on the basis of optical data concerning the dispersion relation of metals such as gold and copper. Realistic permittivities imply, in accordance with basic thermodynamic considerations, that the transverse electric zero mode does not contribute. This results in observable differences ...

The temperature dependence of the Casimir force between a real metallic plate and a metallic sphere is analyzed on the basis of optical data concerning the dispersion relation of metals such as gold and copper. Realistic permittivities imply, together with basic thermodynamic considerations, that the transverse electric zero mode does not contribute. This results in observable differences from ...

In this article we discuss how dispersionbased measurements are affected by multiple-access networks, such as IEEE 802.11-based ad-hoc networks. We study four topics: variable link capacity, movement of wireless nodes, loss rate and timing issues. We show by simulations that the link capacity in a wireless topology is changing due to cross traffic generated from nodes using the same radio frequ...

The structure and dynamics of enigmatic hexa(3,5-di-tert-butylphenyl)ethane was characterized via NMR spectroscopy for the first time. Our variable temperature NMR analysis demonstrates an enthalpy– entropy compensation that results in a vanishingly low dissociation energy (DG d 1⁄4 1.60(6) kcal mol ). An in silico study of increasingly larger all-meta alkyl substituted hexaphenylethane derivat...

The present study explores if EEG spectral parameters can discriminate between healthy elderly controls (HC), Alzheimer's disease (AD) and vascular dementia (VaD) using. We considered EEG data recorded during normal clinical routine with 114 healthy controls (HC), 114 AD, and 114 VaD patients. The spectral features extracted from the EEG were the absolute delta power, decay from lower to higher...

Article history: Received 7 April 2011 Received in revised form 17 September 2011 Accepted 18 September 2011 Is wind direction an adequate marker of air mass history? This review looks at the evolution of methods for assessing the effect of the origin and pathway of air masses on composition change and trends. The composition of air masses and how they evolve and the changing contribution of so...

Atopic dermatitis (AD) is a complex skin disease primarily characterized by psoriasis of the stratum corneum. AD drugs have usually been used in acidic and hydrophilic solvents to supply moisture and prevent lipid defects. Ceramide is a typical treatment agent to regenerate the stratum corneum and relieve symptoms of AD. However, ceramide has limitation on direct use for skin because of its low...

OBJECTIVE Patients with lung emphysema show increased aerosol-derived dimensions of peripheral airspaces and increased aerosol bolus dispersion (AD). To apply these tests in epidemiologic studies, the objective of this pilot study was to investigate whether morphometric changes caused by lung fibrosis can be distinguished from those caused by emphysema. DESIGN This study was designed as a cro...

The Cn parameters are the dispersion coefficients while R is the distance between the two nuclei. The procedures for determining the dispersion coefficients for identical atoms in two spherically symmetric states are known and there has been a lot of activity in calculating the van der Waals coefficients for such atoms 3–9 . When one of the atoms is in a state with nonzero angular momentum the ...
