Synchronization of the Frenet-Serret linear system with a chaotic nonlinear system by feedback of states

A synchronization procedure of the generalized type in the sense of Rulkov et al [Phys. Rev. E 51, 980 (1995)] is used to impose a nonlinear Malasoma chaotic motion on the Frenet-Serret system of vectors in the differential geometry of space curves. This could have applications to the mesoscopic motion of biological filamentsComment: 12 pages, 7 figures, accepted at Int. J. Theor. Phy

2-Approximation algorithm for finding a spanning tree with maximum number of leaves

We study the problem of finding a spanning tree with maximum number of leaves. We present a simple 2-approximation algorithm for the problem, improving on the previous best performance ratio of 3 achieved by algorithms of Ravi and Lu. Our algorithm can be implemented to run in linear time using simple data structures. We also study the variant of the problem in which a given subset of vertices are required to be leaves in the tree. We provide a 5/2-approximation algorithm for this version of the proble

A New Era in Asthma Management: Assessment of Asthma Control

Asthma is recognized as a chronic, heterogenous disease characterized by airway inflammation and a history of respiratory symptoms (eg, wheeze, shortness of breath, chest tightness, or cough) that vary over time and in intensity.1 Variations are often triggered by factors such as exercise, allergen or irritant exposure, change in weather, or viral respiratory tract infections. Asthma symptoms and airflow limitation may resolve spontaneously or in response to treatment. Symptoms may be absent for weeks or months, yet airway hyperresponsiveness related to chronic airway inflammation usually persists
