LTE (telecommunication)

LTE (Long-Term Evolution, commonly marketed as 4G LTE) is a standard for wireless communication of high-speed data for mobile phones and data terminals. It is based on the GSM/EDGE and UMTS/HSPA network technologies, increasing the capacity and speed using a different radio interface together with core network improvements. The standard is developed by the 3GPP (3rd Generation Partnership Project) and is specified in its Release 8 document series, with minor enhancements described in Release 9.

LTE is the natural upgrade path for carriers with both GSM/UMTS networks and CDMA2000 networks. The different LTE frequencies and bands used in different countries will mean that only multi-band phones will be able to use LTE in all countries where it is supported.

Although marketed as a 4G wireless service, LTE (as specified in the 3GPP Release 8 and 9 document series) does not satisfy the technical requirements the 3GPP consortium has adopted for its new LTE Advanced standard. The requirements were originally set forth by the ITU-R organization in its IMT Advanced specification. However, due to marketing pressures and the significant advancements that WiMAX, Evolved HSPA and LTE bring to the original 3G technologies, ITU later decided that LTE together with the aforementioned technologies can be called 4G technologies. The LTE Advanced standard formally satisfies the ITU-R requirements to be considered IMT-Advanced. To differentiate LTE Advanced and WiMAX-Advanced from current 4G technologies, ITU has defined them as "True 4G".

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.
