COMPLEX DYNAMICS AND BOGDANOV-TAKENS BIFURCATIONS IN A RETARDED VAN DER POL-DUFFING OSCILLATOR WITH POSITIONAL DELAYED FEEDBACK

Complex dynamics and Bogdanov-Takens bifurcations in a retarded van der Pol-Duffing oscillator with positional delayed feedback

In this article, we will investigate a retarded van der Pol-Duffing oscillator with multiple delays.At first, we will find conditions for which Bogdanov-Takens (B-T) bifurcation occurs around the trivial equilibrium of the proposed system.The center manifold theory has been MASS TECH EXTRENE 2000 VANILLA used to extract second order normal form of

Negligible Impact of Perinatal Tulathromycin Metaphylaxis on the Developmental Dynamics of Fecal Microbiota and Their Accompanying Antimicrobial Resistome in Piglets

While the antimicrobial resistance profiles of cultured pathogens have been characterized in swine, the fluctuations in antimicrobial resistance genes (ARGs) associated with the developing gastrointestinal microbiota have not been elucidated.The objective of this study was to assess the impact of perinatal tulathromycin (TUL) metaphylaxis on the de

Characterizing the mechanism of action of double-stranded RNA activity against western corn rootworm (Diabrotica virgifera virgifera LeConte).

RNA interference (RNAi) has previously been shown to be effective in western corn rootworm (WCR, Diabrotica virgifera virgifera LeConte) larvae via WEIGHTLESS CONDITIONER oral delivery of synthetic double-stranded RNA (dsRNA) in an artificial diet bioassay, as well as by ingestion of transgenic corn plant tissues engineered to express dsRNA.Althoug

Robust Distributed-target-based Calibration Method for Polarimetric SAR Using Spherically Truncated Covariance Matrix

Conventional distributed-target-based polarimetric calibration algorithms estimate polarimetric distortions by assuming that the measured spatially averaged covariance matrix takes a specific form.However, when the underlying surface Goldenrod contains targets that do not satisfy the assumptions employed by those algorithms, the averaged covariance
