Lipids, EarlyView.ABSTRACT Background: Post‐transplant diabetes mellitus (PTDM) is a common complication following liver transplant (LT) and is associated with adverse outcomes. The triacylglycerol‐glucose product (TyG) and the triacylglycerol‐to‐high‐density lipoprotein (HDL) cholesterol ratio (TAG/HDL‐c) are indices that can serve as triacylglycerol‐based proxies for ...

Dynamic Safe Transmit Power MAC protocol in Wireless Adhoc MAC protocol
TENCON 2011 - 2011 IEEE Region 10 Conference, 2011Adhoc Wireless network's performance is always measured by the number of packets successfully transmitted corresponding to power consumption of the nodes. This indirectly quantifies the battery's life. In multihop wireless networks, every node acts as intermediate node to forward packets to other nodes.

Adaptability in the B-MAC+ Protocol
2008 IEEE International Symposium on Parallel and Distributed Processing with Applications, 2008In order to obtain maximum energetic efficiency, wireless sensor networks must be able to tailor their mode of operation at every level of the software infrastructure. At the MAC level, adaptability can greatly improve the performance of the system by tuning the parameters of operation of the protocol on the base of the communication pattern of the ...

CRMA MAC protocol: A simulative analysis
Computer Communications, 1993This paper reports on an extended simulation analysis of the Cyclic Reservation Multiple Access (CRMA) Media Access Control (MAC) protocol. The analysis is divided into two parts. In the first part we study CRMA in underload conditions, i.e. when the offered load is lower than the medium capacity. In the second part we study CRMA in overload conditions,

Performance Evaluation of MAC Protocols
1996When a new system is designed, different alternatives offering the same functionality have to be compared with respect to performance, reliability, modularity, robustness, hardware and software complexity, development costs etc. In particular when no implementations are available, modelling is often the only way of evaluating and comparing the ...

MAC Protocol Engine for Sensor Networks
GLOBECOM 2009 - 2009 IEEE Global Telecommunications Conference, 2009We present a novel approach for Medium Access Control (MAC) protocol design based on protocol engine. Current way of designing MAC protocols for a specific application is based on two steps: First the application specifications (such as network topology and packet generation rate), the requirements for energy consumption, delay and reliability, and the

MAC-ASA: A New MAC Protocol for WMNs
2007 16th International Conference on Computer Communications and Networks, 2007This paper presents a novel medium access control (MAC) protocol intended to provide multi-hop wireless mesh networks with a higher throughput. The proposed MAC-ASA (medium access control with anticipated scheduling and agreement) protocol uses a modified version of the 802.11 CSMA/CA contention handling procedure integrated with a dynamic (time ...

Computer Networks and ISDN Systems, 1994
Abstract In this paper we describe the S++ protocol, a new protocol designed for Gbit/s LANs. The S++ protocol has evolved from our experience with an earlier protocol, called S, which was implemented as part of a Gbit/s LAN project. Our experience with S enabled us to identify ways by which the performance could be significantly improved while ...
