Time division duplex systems, in a convenient way, facilitates the implementation of asymmetrical links required to efficiently handle the increasingly asymmetric traffic offered by current and future wireless applications. If boundaries between uplink and downlink time-slots are not synchronized among cells, e.g. when different asymmetries are required in different cells, inter-base station (I...

background: the impact of positive intramammary lymph node (im ln) on the prognosis of patients with breast cancer has been debated for years; likewise, the standard management of patients with positive im ln remains unclear, especially when it is identified by preoperative imaging or by sentinel lymph node biopsy. the present study aims at reviewing the level of concurrent involvement of im ln...

The article presents a new scalable iterative method for linear programming called the “apex method”. key feature of this is constructing path close to optimal on surface feasible region from certain starting point exact solution problem. refers minimum length according Euclidean metric. apex based predictor—corrector framework and proceeds in two stages: quest (predictor) target (corrector). s...
