Dear Sirs, As a health economist, I read with interest the article by Mahan et al. which calculates the monetary burden of deep-vein thrombosis (DVT) in the absence of pulmonary embolism (PE) (1). Mahan et al. multiply numbers of incident and recurrent DVT cases by average costs per incident or recurrent case. That approach requires estimates of incidence and recurrence derived from population-...

The formalism for a linear-response many-body treatment of the electronic contributions to thermal transport is developed for multilayered nanostructures. By properly determining the local heat-current operator, it is possible to show that the Jonson-Mahan theorem for the bulk can be extended to inhomogeneous problems, so the various thermal-transport coefficient integrands are related by power...

Representation aiding (and similar approaches that share the general orientation) has a great deal of utility, predictive ability, and explanatory power. Marino and Mahan (2005) discuss principles that are critical to the RA approach (configurality, emergent features, and mappings) in a reasonable fashion. However, the application of these principles is far from reasonable. The authors explicit...

Thermoelectric phenomena in photoexcited graphene have been the topic of several theoretical and experimental studies because their potential usefulness optoelectronic applications. However, available descriptions thermoelectric effect terms Seebeck coefficient do not take into account role electron density. In this work, we adopt concept effective [G.D. Mahan, J. Appl. Phys. 87, 7326 (2000)] e...

member of the encyclopedia of the world of islam. many historians have researched about abbasides' rebellion, repeatedly, as one of the most important events of the early islam. however,there are no convincing replies for numerous questions about this subject yet. and there are still a lot for the researchers to find out about in this regard. in this article, by introducing one of the grea...

Pasteurella multocida is the causative agent of infectious diseases of economic importance such as fowl cholera, bovine hemorrhagic septicemia, and porcine atrophic rhinitis. However, knowledge of the molecular mechanisms and determinants that P. multocida requires for virulence and pathogenicity is still limited. To address this issue, we developed a genetic expression system, based on the in ...

The thermoelectric figure of merit (ZT) in narrow conduction bands of different material dimensionalities is investigated for different carrier scattering models. When the bandwidth is zero, the transport distribution function (TDF) is finite, not infinite as previously speculated by Mahan and Sofo [Proc. Natl. Acad. Sci. U.S.A. 93, 7436 (1996)], even though the carrier density of states goes t...

Temperature-dependent radiative recombination of free excitons involving one or two LO phonons in GaN is investigated in detail. It is found that both phonon sidebands possess asymmetric lineshapes and their energy spacings from the zero-phonon line strongly deviate from the characteristic energy of LO phonons as the temperature increases. Furthermore, the deviation rates of oneand two-phonon s...
