Wolbachia are very common, maternally transmitted endosymbionts of insects. They often spread by a mechanism termed cytoplasmic incompatibility (CI) that involves reduced egg hatch when Wolbachia-free ova are fertilized by sperm from Wolbachia-infected males. Because the progeny of Wolbachia-infected females generally do not suffer CI-induced mortality, infected females are often at a reproduct...

The propagation of information, cascading behavior, spread of ideas, viruses and diseases through a network have been studied in different contexts, such as viral marketing (Kempe et al., 2003), the spread of news and opinions (Adar et al., 2004), the spread of technological inovations (Rogers, 1999), and the spread of infectious diseases (Anderson et al., 1992). In such cases, we have a set of...

Monoclonal proliferative lesions may be identified by X chromosome inactivation skewing relative to normal polyclonal tissues. We have quan titatively analyzed X-inactivation patterns throughout polyclonal uterine tissues to develop interpretive criteria for recognition of monoclonal neoplasms. Six fresh tissue samples (two samples each of cervix, endometrium, and myometrium) were collected fro...

The performance of orthogonal frequency-division multiplexing (OFDM) system with multiple-symbol differential detection (MSDD) is analyzed over both timeand frequency-selective Rayleigh fading channels. The optimal decision metrics of timedomain MSDD (TD-MSDD) and frequency-domain MSDD (FD-MSDD) are derived by calculating the exact covariance matrix under the assumption that the guard time is l...

| Non-coherent detectors for initial code synchronization (acquisition) of BPSK direct sequence spread spectrum signals on an AWGN channel are analyzed. In addition to the thermal noise, in many applications such detectors are faced with the \self-noise", due to the partial period correlations. Under the random code sequences assumption, in this paper an exact analysis of the non-coherent corre...

Correctness problems in the iBGP routing, the de-facto standard to spread global routing information in Autonomous Systems, are a well-known issue. Configurations may route cost-suboptimal, inconsistent, or even behave non-convergent and -deterministic. However, even if a lot of studies have shown many exemplary problematic configurations, the exact scope of the problem is largely unknown: Up t...

In this paper, we study the fuzzy Fredholm integral equations of product type. As a special case, type arise, e.g., in spread an infectious disease that does not induce permanent immunity. Because importance and practicality such integrals, prove existence uniqueness solution these with help Banach fixed point theorem. Finally, obtain error estimation between exact iterative method. Examples sh...

Abstract Reaction-diffusion models are used in different areas of chemistry problems. Also, coupled reaction-diffusion systems describing the spatiotemporal dynamics of competition models have been widely applied in many real world problems. In this paper, we consider a coupled fractional system with diffusion and competition terms in ecology, and reaction-diffusion growth model of fractional o...
