Dietary patterns and the adenomacarcinoma sequence of colorectal cancer

Abstract: Background Food components of a diet are highly related, so that building up dietary patterns may help understand the relationship between chronic diseases and diet, and identify high risk groups that need preventive advice.

Evaluation Based upon Stochastic Petri Nets of the Maximum Throughput of a Full Duplex Protocol

Abstract: This paper introduces some principles and tools which can be used to evaluate the maximum throughput of a class of computing processes The function of these processes is to manage queues in computer systems (device handlers, communication protocols) Our approach is based upon stochastic Petri net models We show how the theorem on maximum rate (Lavenberg) can be applied to stochastic Petri nets This theoretical result and a general purpose evaluation software tool allows the numerical evaluation of maximum throughput rates As an example, the maximum throughput of a full duplex protocol is computed

Green Opportunistic and Efficient Resource Block Allocation Algorithm for LTE Uplink Networks

Abstract: This work proposes a new radio resource allocation scheme for the green uplink Long-Term Evolution (LTE) networks. The proposed scheme aims at efficiently allocating the resource blocks (RBs) and the transmission power of the user equipment (UE). The allocation of RBs is based on the opportunistic and efficient RB allocation (OEA) algorithm, whose objective is to maximize the aggregate throughput while being subjected to single-carrier frequency-division multiple-access (SC-FDMA) constraints. An evolution of the algorithm, which is called quality-of-service (QoS)-based OEA, providing QoS differentiation, is also presented. It allocates a given maximum number of RBs to each UE, which is set according to the user's QoS requirements. Once the allocation of RBs is completed, the allocation of the UE transmission power is performed. The transmission power considers the UE channel conditions over its whole allocated RBs. Its value is reduced as much as possible and adjusted such that the user's required QoS satisfies throughput demand previously determined by the RB allocation. The proposed radio resource management algorithm has several interesting properties. It maximizes the aggregate throughput, decreases the ratio of inefficiently allocated RBs, cancels the RB's wastage, and increases the energy efficiency without affecting the user's throughput. Furthermore, the OEA algorithms can be implemented in LTE hardware equipment devices on account of their low computational complexity.
