Colored noise in oscillators. Phase-amplitude analysis and a method to avoid the Ito-Stratonovich dilemma

We investigate the effect of time-correlated noise on the phase fluctuations of nonlinear oscillators. The analysis is based on a methodology that transforms a system subject to colored noise, modeled as an Ornstein-Uhlenbeck process, into an equivalent system subject to white Gaussian noise. A description in terms of phase and amplitude deviation is given for the transformed system. Using stochastic averaging technique, the equations are reduced to a phase model that can be analyzed to characterize phase noise. We find that phase noise is a drift-diffusion process, with a noise-induced frequency shift related to the variance and to the correlation time of colored noise. The proposed approach improves the accuracy of previous phase reduced models

Draft Genome Sequence of the Serratia rubidaea CIP 103234T Reference Strain, a Human-Opportunistic Pathogen.

We provide here the first genome sequence of a Serratia rubidaea isolate, a human-opportunistic pathogen. This reference sequence will permit a comparison of this species with others of the Serratia genus

Lighting the female fuse: group fusion, devoted actors, and female suicide bombers

This thesis intends to revise and update devoted actor theory (DAT) by introducing a neglected dataset—female suicide bombers. DAT provides one such theoretical framework for understanding extremist group behavior and, to a lesser extent, suicidal bombing. DAT is largely satisfying: its claims and conclusions address relevant issues and provide compelling answers to critical questions. However, it is not without its analytical and empirical gaps. Crucially, DAT does not explicitly account for the narratives and characteristic motives of female suicide bombers—which often differ in logic, content, and tone from those of their male counterparts. In addition, DAT assumes that people who are fused with extreme groups are willing to self-sacrifice for their group, but the theory does not account for how this fusion process transpires. Therefore, I propose two amendments to DAT that not only address theoretical issues, which arise partially from the lack of female terrorist accounts, but also creates a narrative that bridges the gap that would explain how an individual progresses from bonding to a group to making the decision to die for it. Accordingly, I also propose to theorize a psychosocial process that links the way in which individuals, specifically females, become fused to a group and edge closer to the most extreme of extremist decisions: to annihilate their bodies and selves, while at the same time annihilating or wreaking havoc upon the lives of others whom they have deemed enemies of themselves or their group
