Abstract Introduction: Achievement of new drugs with minimal side effects is a important goal in the cancer treatment due to irreversible side effects of conventional drugs. Tricalcium phosphates as natural bone components have unique characteristics including excellent biocompatibility, high biosorption and superior bioactivity. This research aimed at investigating the inhibitory effect of tr...

This paper presents several considerations on the hybrid TCP congestion control, in which lossbased schemes like TCP-Reno and delay-based schemes like TCP-Vegas are combined in a smart way. We firstly introduce simple analytical models of loss-based TCP, delay-based TCP and their hybrid. With support of experimental results, effectiveness of the hybrid TCP is proved. Then, we try to develop a m...

The idea of Internet everywhere makes the assumption that an Internet access should be available even in remote areas without network infrastructure. In this case satellite access represents an attractive solution. Nevertheless, experience shows that over satellite links, TCP is limited in terms of data speeds. Many enhancements and solutions, based for instance on tuning TCP parameters or TCP ...

Porous β-tricalcium phosphate (TCP) displays osteoinductivity in certain animals in the absence of osteoinductive agents. We evaluated whether the microstructure may be an important determinant of osteoinduction, and also investigated how bone formation was promoted using β-TCP combined with bone marrow aspirates. We prepared two types of β-TCP, namely, β-TCP A, which possessed interconnected m...

Transmission control protocol (TCP) was initially designed for static networks to provide the consistent data delivery. The enhancement of TCP performance was also achieved with different types of networks with the introduction of new TCP deviations. However, there are still many factors that affect the performance of TCP. Mobility is one of the primary performance-affecting drivers in heteroge...

Among Internet services that have recently been initiated, including data GRID network and storage area network (SAN), the server machines have gigabit-level network interfaces such as Gigabit Ethernet, and directly connect to high-speed network to deliver gigabyte/terabyte data to other hosts. Although these services require a large amount of network bandwidth and disk storage, such services w...

We analyze the performance of TCP and TCP with network coding (TCP/NC) in lossy wireless networks. We build upon the simple framework introduced by Padhye et al. and characterize the throughput behavior of classical TCP as well as TCP/NC as a function of erasure rate, roundtrip time, maximum window size, and duration of the connection. Our analytical results show that network coding masks rando...

The traditional TCP/IP protocol stack is associated with shortcomings related to the context-switching overhead and redundant data copying. The software-based TOE (TCP/ IP Offload Engine), also known as lightweight TCP/IP, was developed to optimize the TCP/IP protocol stack to run on an embedded system. In this paper, we propose the design of a lightweight TCP/IP protocol stack that runs on an ...

Transmission mechanisms that include an available bandwidth estimation algorithm and a packet loss differentiation scheme, in general, exhibit higher TCP performance in wireless networks. TCP New Jersey, known as the best existing scheme in terms of goodput, improves wireless TCP performance using the available bandwidth estimation at the sender and the congestion warning at intermediate router...
