background and purpose: the identification of genetics risk factors of human diseases is very important. this study is conducted to model the allele frequencies (afs) of alzheimer’s disease. materials and methods: in this study, several candidate probability distributions are fitted on a data set of alzheimer’s disease genetic risk factor. unknown parameters of the considered distributions are ...

In this communication, a preliminary analysis of the solution of microwave imaging problems for ground penetrating radar applications has been proposed. Such a task has been fulfilled by exploiting the theory of compressive sensing in a linearized multiview-multistatic single-frequency framework.

The design of broadcasting networks operating in a single frequency way is challenging due to the difficulty of predicting the performance in a frequency selective channel, caused by natural multipath and echoes coming from different transmitters. In this paper we resort to the use of frame error rate prediction metrics (also known as effective SNR metrics) to characterize the performance gain ...

A solution for multifrequency plane waves propagating through a dissipative and nonlinear medium is presented. It originates from the well-known Bessel function series ratio for a pure sinusiodal wave, introduced by Cole and Mendousse. The solution is exact. The only limitation, inherited from the single-frequency solution, is the slow convergence of the series when the nonlinearity is very lar...

A novel and compact Er-Yb: glass laser was developed with single-frequency output power 10 mW in a wavelength range from 1531 to 1547 nm. The laser output was efficiently frequency doubled at 770.1 nm in a single-pass periodically poled lithium niobate waveguide and a second harmonic power in excess of 15 W was achieved, with an internal conversion efficiency of 220% W 1. This frequency-doubled...

For a Nd:YVO4 crystal, a strong thermal lens astigmatism is observed by using a probe beam technique. By orienting the c-axis of the Nd:YVO4 crystal in the tangential plane of the ring resonator, we find the two astigmatisms introduced by the ring cavity and thermal lens can be mutually compensated. Such compensation improves the stability, beam quality, and conversion efficiency of the laser. ...

Abstract Exploiting the fundamental features of quantum mechanics, an entanglement-based network offers a promising platform for many dramatic applications such as multi-user cryptography. Nevertheless, implementation large-scale in real-world scenarios remains challenging owing to multiple scattering events complex environment, particularly those frequency-sensitive scatterings that disturb co...
