E-UTRA

e-UTRA is the air interface of 3GPP's Long Term Evolution (LTE) upgrade path for mobile networks. It is an acronym for evolved UMTS Terrestrial Radio Access, also referred to as the 3GPP work item on the Long Term Evolution (LTE) also known as the Evolved Universal Terrestrial Radio Access (E-UTRA) in early drafts of the 3GPP LTE specification. E-UTRAN is the initialism of Evolved UMTS Terrestrial Radio Access Network and is the combination of E-UTRA, UEs and EnodeBs.

It is a radio access network standard meant to be a replacement of the UMTS and HSDPA/HSUPA technologies specified in 3GPP releases 5 and beyond. Unlike HSPA, LTE's E-UTRA is an entirely new air interface system, unrelated to and incompatible with W-CDMA. It provides higher data rates, lower latency and is optimized for packet data. It uses OFDMA radio-access for the downlink and SC-FDMA on the uplink. Trials started in 2008.

Features

EUTRAN has the following features:

Leukotriene E4

Leukotriene E4 (LTE4) is a cysteinyl leukotriene involved in inflammation. It is known to be produced by several types of white blood cells, including eosinophils, mast cells, tissue macrophages, and basophils, and recently was also found to be produced by platelets adhering to neutrophils. It is formed from the sequential conversion of LTC4 to LTD4 and then to LTE4, which is the final and most stable cysteinyl leukotriene. Compared to the short half lives of LTC4 and LTD4, LTE4 is relatively stable and accumulates in breath condensation, in plasma, and in urine, making it the dominant cysteinyl leukotriene detected in biologic fluids. Therefore, measurements of LTE4, especially in the urine, are commonly monitored in clinical research studies.

Increased production and excretion of LTE4 has been linked to several respiratory diseases, and urinary LTE4 levels are increased during severe asthma attacks and are especially high in people with aspirin-induced asthma, also known as Samter’s Triad or aspirin-exacerbated respiratory disease (AERD).

Liquid Tension Experiment 2

Liquid Tension Experiment 2 is the second and final studio album by instrumental rock/progressive metal supergroup Liquid Tension Experiment, released on June 15, 1999 through Magna Carta Records. The album reached No. 8 on the Billboard Top Internet Albums chart and No. 40 on Billboard's Heatseekers.

Overview

Each song is described by the band in detail within the liner notes. Bassist Tony Levin almost exclusively used a Chapman Stick to record the album's bass parts. The only 'real' bass guitar appears on the faux-accordion/reggae section of "Another Dimension"; Levin also used a fretless bass for the intro to "Biaxident", which takes its name from Biaxin, a medicine that guitarist John Petrucci was taking during the recording sessions to combat severe headaches, as well as being a play on "by accident".

In the middle of the recording sessions, Petrucci had to leave the studio when he got word that his pregnant wife had gone into labor. This left the other three band members to carry on recording by themselves. This is how "When the Water Breaks" got its name, for it was the song the band were working on when Petrucci got the news. The song contains a baby sound effect (a "baby soundscape", according to keyboardist Jordan Rudess) to mark the particular section the band had been writing upon Petrucci's departure.
