Joint Brain Parametric T1-Map Segmentation and RF Inhomogeneity Calibration by Ping-Feng Chen, R. Grant Steen, Anthony Yezzi, Hamid Krim

“…This method assumes the average T1 value of white matter is the same across transverse slices in the central brain region, and JSRIC is able to rectify the flip angles to generate calibrated T1-Maps. In order to generate an accurate T1-Map, the determination of optimal flip-angles and the registration of flip-angle images are examined. …”

A new RS steganalysis algorithm of detecting UnderMP3Cover by Jian ZHANG, Rangding WANG, Diqun YAN

“…A new RS steganalysis algorithm to attack UnderMP3Cover was proposed.By analyzing the error caused by the RS algorithm,the choice of resolution function,the initial bias and the fitting method were modified,the flip operator was also selected in the experiment.Experimental results demonstrate that the proposed method can estimate the length of embedded message effectively and the average error reduces to 2%,which is better than the existing algorithms.…”

Bifurcation and Chaotic Behavior of a Discrete-Time SIS Model by Junhong Li, Ning Cui

“…It is verified that there exist some dynamical behaviors in this model, such as transcritical bifurcation, flip bifurcation, Hopf bifurcation, and chaos. The numerical simulations, including bifurcation diagrams and computation of Lyapunov exponents, not only show the consistence with the theoretical analysis but also exhibit the rich and complex dynamical behaviors.…”

Retour critique sur la mobilisation du concept de ‎résilience en lien avec l’adaptation des systèmes urbains au changement climatique by Béatrice Quenault

“…It interrogates firstly the real reasons of the actual successfulness of the concept of resilience, then it breaks off with the dominant flip-side approach of vulnerability and resilience which both are considered as the reverse polarity (negative versus positive) of the same medal and finally, it argues the idea more and more communally admitted that resilience represents a new paradigm of both risks management and urban sustainable planning in link with climate change.…”

Critical bifurcation surfaces of 3D discrete dynamics by Michael Sonis

“…It is proven that 3D domain of asymptotic stability (attraction) of the fixed point for a given 3D discrete dynamics is bounded by three critical bifurcation surfaces: the divergence, flip and flutter surfaces. The analytical construction of these surfaces is achieved with the help of classical Routh–Hurvitz conditions of asymptotic stability. …”
