Association of Skeletal Muscle, Body Fat and Frailty With Prolonged Length of Hospital Stay Following Colectomy for Adenocarcinoma: A Pilot Case-Control Study. [PDF]

open access: yesHealth Care Sci
ABSTRACT Physical fitness is well‐known to be associated with health outcomes. This pilot study examined the impact of different measures of fitness on length of stay following colectomy. A case‐control study was designed to evaluate the effect of skeletal muscle mass, body fat, and frailty measures on post‐operative length of stay (LOS).

Comparing Delay-Constrained ALOHA and CSMA: A Learning-Based Low-Complexity Approximate Approach

open access: yesIEEE Open Journal of the Communications Society, 2021
Supporting delay-constrained traffic becomes more and more critical in multimedia communication systems, tactile Internet, networked control systems, and cyber-physical systems, etc. In delay-constrained traffic, each packet has a hard deadline.

Experimental Demonstration of Delay-Bounded Wireless Network Based on Precise Time Synchronization

open access: yesIEEE Access, 2022
Low latency and reliable information transfer are highly demanded in fifth generation (5G) and beyond 5G wireless communications. A novel delay-bounded wireless media access control (MAC) protocol called Carrier Sense Multiple Access with Arbitration ...

On the fairness of large CSMA networks [PDF]

open access: yesIEEE Journal on Selected Areas in Communications, 2009
We characterize the fairness of decentralized medium access control protocols based on CSMA/CA, in large multi-hop wireless networks. In particular, we show that the widely observed unfairness of these protocols in small network topologies does not always persist in large topologies. In regular networks, this unfairness is essentially due to the unfair

Asymptotic performance characteristics of CSMA and CSMA ← CD → CSMA/CD networks [PDF]

open access: yesMathematical Problems in Engineering, 1996
This paper presents analytical formulae for performance evaluation of CSMA and CSMA/CD networks with a finite number of buffered users. The asymptotic theory developed in [1] is extended to local area networks so as to investigate the resulting steady state throughput, time delay, probability of blocking, and local stability of each equilibrium.

Distributed CSMA with pairwise coding [PDF]

open access: yes2013 Proceedings IEEE INFOCOM, 2013
We consider distributed strategies for joint routing, scheduling, and network coding to maximize throughput in wireless networks. Network coding allows for an increase in network throughput under certain routing conditions. We previously developed a centralized control policy to jointly optimize for routing and scheduling combined with a simple network

Creating a Functional Biomimetic Cartilage Implant Using Hydrogels Based on Methacrylated Chondroitin Sulfate and Hyaluronic Acid

open access: yesGels, 2022
The load-bearing function of articular cartilage tissue contrasts with the poor load-bearing capacity of most soft hydrogels used for its regeneration. The present study explores whether a hydrogel based on the methacrylated natural polymers chondroitin ...
