Bronchiolar adenoma (BA) is a benign lung tumor characterized by nodular proliferation of bilayered bronchiolar-type epithelium with continuous basal cell layer. The genetic characteristics BA are not well understood. However, mutations commonly associated adenocarcinoma, such as BRAF V600E, epidermal growth factor receptor (EGFR) mutations, and ALK rearrangements, have recently been identified in this context. This report describes case 43-year-old male who presented mixed ground-glass...

This paper studies the achievable rate and power allocation to improve uplink (UL) spectrum efficiency in a Long-Term Evolution Advanced (LTE-A) cooperative cellular network with deployment of Type-II in-band decode-and-forward (DF) relay stations (RSs). The physical-layer UL transmission technology is based on single-carrier frequency-division multiple access (SC-FDMA) frequency-domain equalization (FDE). Different from downlink (DL) orthogonal FDMA system, signals all subcarriers SC-FDMA...

Quality of service multicast routing is an important research topic in networks. Research has sought to obtain a tree at the lowest cost that satisfies bandwidth, delay and jitter constraints.

A novel method for measuring the modulation efficiency of electrooptic phase modulators is proposed based on fiber-dispersion-induced signal fading. The fiber dispersion spectrally alters relative phasing modulated and leads to fading recovered electrical signal, from which obtained in case a given dispersion. frequency-dependent index half-wave voltage are experimentally measured commercial modulator, agree well with results using conventional technique.

In WCDMA, uplink radio resources are shared by multiple users and the resource management (RRM) is done at UTRAN (UMTS Terrestrial Radio Access Network). this paper, link system performance of WCDMA evaluated using different techniques such as retransmissions with incremental redundancy (IR), short frame durations fast scheduling. It seen that efficiency can be improved IR, while traffic delays reduced cell throughput enhanced scheduling durations.
