We present international evidence on the marriage market implications of cohort size growth, and set out a theoretical model of how marriage markets adjust to imbalances. Since men marry younger women, secular growth in cohort size in the second phase of the demographic transition worsens the position of women. This e¤ect has been substantial in many Asian countries earlier, and continues to be...

In this paper we present some classes of high-order semi-Lagrangian schemes for solving the periodic one-dimensional Vlasov-Poisson system in phase-space on uniform grids. We prove that the distribution function f(t, x, v) and the electric field E(t, x) converge in the L2 norm with a rate of O ( ∆t + h + hm+1 ∆t ) , where m is the degree of the polynomial reconstruction, and ∆t and h are respec...

A new method for measuring the quantities influenced by bin-to-bin and inside bin correlations is presented. This method is essential for large multiplicity and/or high density of particles in phase space. The method was applied to the two particle correlation functions of e + e − →W + W − events.

The technique of thermal wave thermography combines advantages of both conventional thermal wave measurement and thermography using a commercial IR camera. This technique allows for shorter imaging time and depth profiling. Non-uniformity of heating area and optical surface structures can be suppressed in phase images. Several examples show the potential applications of thermal wave thermograph...

The modulation of the vertical flux of kinetic energy to the stratosphere by the pressure-work effect at 100 mb is compared with variations in the hemispheric kinetic cnergy, the horizontal momentum and heat transports a t “low” latitudes, and the tropical zonal wind and temperature for the lower stratosphere. It is deduced that the variation of the vertical flux of geopotential is in phase wit...

Three different topics in phase-field modelling of solidification are discussed, with particular emphasis on the limitations of the currently available modelling approaches. First, thin-interface limits of two-sided phasefield models are examined, and it is shown that the antitrapping current is in general not sufficient to remove all thin-interface effects. Second, orientation-field models for...

Formerly neglected, typical food products nowadays support a higher involvement of an increasing number of farmers as well as they seem to be in phase with consumers’ expectations. Since directives 2081/92 and 2082/92 European Union had set up PDO and PGI labels as means of valorisation with benefits to typical food products. This paper aims firstly at considering typical food products with res...

A new multiphase sinusoidal oscillator is presented. The circuit realization uses the four-terminal floating nullor(FTFN)to generate arbitrary n current sinusoidal signals equally spaced in phase. The proposed circuit consists of n CCCIIs, n grounded capacitors and 2n grounded resistors. The oscillation condition and oscillation frequency are independently controlled. The former depends on the ...

the microstructure of dual phase steels can be considered as a matrix of ferrite phase reinforced by martensite particles. recent measurements show that the mechanical properties of the ferrite phase are changed with the distance from the martensite grains. in this paper, a new method has been proposed to consider this phenomenon in finite element modeling of dual phase steels microstructure. i...

the early cytokines production in response to live logarithmic and stationary phase promastigotes of leishmania major was examined on the peripheral blood cells of the healthy individuals. whole blood cultures were stimulated by either logarithmic or stationary phase promastigotes. ifn- and il-10 productions were assessed by specific sandwich elisa. the results showed that the logarithmic prom...
