Crystals of the one-dimensional organic-inorganic lead iodide-based compound catena-poly[bis-(piperazine-1,4-diium) [[tetra-iodido-plumbate(II)]-μ-iodido] iodide monohydrate], (C4N2H12)2[PbI5]I·H2O, were obtained by slow evaporation at room temperature of a solution containing lead iodide and piperazine in a 1:2 molar ratio. Inorganic lead iodide chains, organic (C4N2H12)(2+) cations, water mol...

In this paper, we study inextensible ows in three dimensional Lie groups with a bi-invariant metric. The necessary and sucient conditions for inextensible curve ow are expressed as a partial dierential equation involving the curvatures. Also, we give some results for special cases of Lie groups.

This paper presents a model to demonstrate that, when di¤erences-of-opinion over individual securities have a common component, the valuation of the aggregate market can be higher than its fundamental, even if all investors agree on the market fundamental. Using analyst forecast dispersion to measure disagreement, I …nd empirical evidence that individual stock disagreements co-move and the comm...

An electromagnetic truncated Gaussian pulse propagates through a waveguide with piecewise diierent dielectric constants. The waveguide contains a barrier, namely a region of a lower dielectric constant compared to the neighboring regions. This setup yields a purely imaginary wave vector in the region of the barrier ('electromagnetic tunneling'). We exactly calculate the time-dependent Green's f...

OBJECTIVE To determine the effects of timing of onset of overweight (OW) on childhood anthropometric adiposity levels using long-term serial data from the Fels Longitudinal Study. CLASSIFICATION OW was defined as body mass index (BMI; kg/m(2)) >25, and the age at first measurement of BMI >25 was the age of onset of OW. Early onset of OW (early-OW) and late onset of OW (late-OW) were defined a...

The generalized integral transform technique (GITT) is applied to solve the one-dimensional advection±dispersion equation (ADE) in heterogeneous porous media coupled with either linear or nonlinear sorption and decay. When both sorption and decay are linear, analytical solutions are obtained using the GITT for one-dimensional ADEs with spatially and temporally variable ̄ow and dispersion coeci...

Non-directed diffuse optical wireless (OW) channels are mainly impaired by multipath propagation, which results in pulse spread and intersymbol interference (ISI). Ambient light noise, however, is also a notable impairment in indoor systems, and can degrade the system performance. In this paper, we present and investigate a new geometry that uses a line strip spot -diffusing transmitter in conj...
