Various outcomes of cholinesterase inhibitor treatment influence survival of patients with Alzheimer’s disease.

Objectives: Various outcomes of cholinesterase inhibitor (ChEI) therapy have been observed in Alzheimer’s disease (AD). It is not clear whether the duration of treatment, type of ChEI, or dose affect mortality. We aimed to investigate the association between ChEI therapy and patient survival. Methods: The Swedish Alzheimer Treatment Study (SATS) is a prospective, observational, multicentre study t

Theory of Inversion of Dispersive Bi-Isotropic Slab Parameters using TEM-Pulses

A new method of reconstructing the causal susceptibility kernels of a homogeneous, temporally dispersive, bi-isotropic medium from generic scattering data at normal incidence is presented. This inverse problem is shown to be well posed in the space of continuous functions furnished with the maximum norm, C[0, T]. A numerical example is given.

Saving Youth from Idleness and Poverty: Vocational Education as a Way towards Discipline and Livelihood in Argentina (1880–1920) and China (1917–1937)

During the second half of the 19th century, both China and Argentina experienced accelerated economic, political, and social changes. To become a 'modern' nation was an integral part of both countries' efforts to deal with these transformations. Education played a key role in this nation-building process: it was expected to shape the national citizen and, thereby, the nation. However, with regard

The Influence of Nitric Oxide on the Occurrence of Autoignition in the End Gas of Spark Ignition Engines

Full-cycle simulations of a spark ignition engine running on a primary reference fuel have been performed using a two-zone model. A detailed kinetic mechanism is taken into account in each of the zones, while the propagating flame front is calculated from a Wiebe function. The initial conditions for the unburned gas zone were calculated as a mixture of fresh gas and rest gas. The composition of th

Forerunners in bi-gyrotropic materials

Forerunners (precursors) in linear, temporally dispersive, bi-gyrotropic materials are investigated using time-domain techniques. Bi-gyrotropic materials are characterized by twelve constitutive parameters (integral kernels). Specifically, the four susceptibility dyadics are all gyrotropic with a common gyrotropic axis. Pulse propagation along this axis is analyzed using dispersive (noncoupling) w
