Polynomial time algorithm for solving k-coverage problem in wireless sensor networks by Qi WANG, Zheng’an XIAO, Huaixing WANG

“…How to solve the k-coverage problem,which was divided into worst-case and best-case,inside the two-dimensional target area in wireless sensor networks was explored,and a polynomial time algorithm for solving this problem was put forward.In this algorithm,a series of definitions and theorems were proposed based on the geometric graph of growing disks,and the k-coverage problem was transformed into one of finding a series of adjacent borders.The simulation results show that the algorithm could compute the optimal k-breach path and k-support path in polynomial time,so as to avoid or select the network coverage reasonably.…”

His bundle pacing – a new word in technology of pacing and treatment of heart failure by Ya.V. Skybchyk, Ye.V. Zhytyns’kiy, О.М. Grytsay, V.О. Kuts, О.J. Zharinov

“…Despite certain temporary limitations – lack of results of the large randomized trials, necessity of the special surgeon's experience in implantation of the electrode, there are reasons to consider His bundle pacing as a promising alternative to the existing methods of treatment of bradyarrhythmias (e.g. classic right ventricular pacing, cardiac resynchronization therapy), particularly in patients with a predicted high (> 40 %) percentage of right ventricular pacing and decreased left ventricular systolic function.…”
