The high-precision measurements of the Hubble parameter make theory cosmic expansion more and confusing, which bolsters idea that new physics may be needed to explain mismatch. Astronomical observations show Universe is expanding exponentially. Free electron Compton scattering (FEC) can produce illusion exponentially Universe: FEC causes photons redshift exponentially, photon beam expands along...
Adjuvant chemotherapy for early breast cancer improves disease-free and overall survival in pre- and postmenopausal women. The importance of maintaining relative dose intensity (RDI) is well-known; however, little information is available from routine clinical practice regarding how well dose intensity is maintained with modern chemotherapy regimens.In a retrospective review of patients undergo...
Ab stract: Ef fec tive ness must be de ter mined for each new tech nol ogy be cause it may have ad van tages and dis ad van tages over what is cur rently of fered. We re viewed the lit er a ture to syn the size in for ma tion on whether telepsychiatry is ef fec tive. Based on the lit er a ture, we sug gest that the ef fec tive ness of telepsychiatry be eval u ated on ac cess to care, qual ity o...
Forward Error Correction (FEC) is seldom used in computer networks, because of perplexity in doing the necessary encoding/decoding in software. We believe this diidence to originate from the fact that error control codes (which FEC is usually based upon) are generally designed and presented stressing their ability to correct errors rather than erasures (i.e. missing data in known locations). Ha...
Silicon has been widely considered as the next generation anode material for lithium-ion batteries, due to its substantially higher capacity compared to conventionally used graphite. However, silicon-based electrodes suffer from problems such as poor capacity retention and low coulombic efficiency. Significant amount of work has been devoted to improve the performance of silicon electrodes. Amo...
This paper reports on the effect of strategic anthelmintic treatments and other determinants on faecal egg counts (FEC) of Trichostrongyles in N'Dama cattle of a west African village. Initially, 527 animals from 13 private N'Dama cattle herds were monitored in a longitudinal study from October 1989 to December 1994. Each herd was stratified by age and animals were sequentially allocated to two ...
BACKGROUND We compared treatment completion rates and safety of docetaxel and cyclophosphamide six- cycle therapy (TC6) with docetaxel followed by 5FU, epirubicin and cyclophosphamide (T-FEC) therapy in Japanese patients with human epidermal growth factor receptor 2 (HER2)-negative breast cancer. MATERIALS AND METHODS We administered TC6 q3w or T-FEC q3w to HER2-negative breast cancer patient...
This paper studies TCP performance improvement in wireless and heterogeneous networks using Forward Error Correction (FEC) technique driven by TCP semantics. In the proposed scheme, called TCP-aware FEC, the amount of redundancy added to a packet at the sender node corresponds to the level of error protection and is computed as a function of TCP congestion window. The TCP-aware FEC becomes stro...
In this paper we investigate the potential gain that can be obtained in DVB-H using application layer forward error correction (AL-FEC) to perform a multi-burst protection of the transmission for improving the reception of streaming services for mobile terminals. Compared to the conventional approach with link layer multi protocol encapsulation FEC (MPE-FEC), this technique allows to increase t...
