Mem
Mem (also spelled Meem or Mim) is the thirteenth letter of the Semitic abjads, including Phoenician Mēm 
, Hebrew Mēm מ, Aramaic Mem 
, Syriac Mīm ܡܡ, and Arabic Mīm م. Its value is [m].
The Phoenician letter gave rise to the Greek Mu (Μ), Etruscan 
, Latin M, and Cyrillic М.
Origins
Mem is believed to derive from the Egyptian hieroglyphic symbol for water,
which had been simplified by the Phoenicians and named after their word for water, mem (
), ultimately coming from Proto-Semitic *maʾ-/*may-.
Hebrew Mem
Hebrew spelling: מֵם
Hebrew pronunciation
Mem represents a bilabial nasal [m].
Variations on written form/pronunciation
In Hebrew, Mem, like Kaph, Nun, Pe, and Tzadi, has a final form, used at the end of words: its shape changes from מ to ם.
Significance
In gematria, Mem represents the number 40 in both the Standard and Mispar Gadol Methods of Gematria; However, (mem sofit) final mem's value is 40 in the Standard Method and 600 in the Mispar Gadol method. The Standard Method adds the values of Tav and Resh (400+200) to denote the value of mem sofit.

In Computational complexity theory, computing efficiency, Combinatorial optimization, Supercomputing, computational cost (Algorithmic efficiency) and other computational metrics, MEMS is a measurement unit for the number of memory accesses used or needed by a process, function, instruction set, algorithm or data structure.
Example usage: "A typical search tree in a (10 x 10 Sudoku or Latin square) requires a node of about 75 mems (memory accesses) for processing, to check validity. Therefore the total running time on a modern processor would be roughly the time needed to perform 7020200000000000000♠2×1020 mems." (Donald Knuth, 2011, The Art of Computer Programming, Volume 4A, p. 6).
Reducing MEMS as a speed and efficiency enhancement is not a linear benefit, as it trades off increases in ordinary operations costs.
PFOR Compression
This optimization technique also is called PForDelta
Although lossless compression methods like Rice, Golomb and PFOR are most often associated with signal processing codecs, the ability to optimize binary integers also adds relevance in reducing MEMS tradeoffs vs. operations. (See Golomb coding for details).
Trench
A trench is a type of excavation or depression in the ground that is generally deeper than it is wide (as opposed to a wider gully or ditch), and narrow compared to its length (as opposed to a simple hole).
In geology, trenches are created as a result of erosion by rivers or by geological movement of tectonic plates. In the civil engineering field of construction or maintenance of infrastructure, trenches are created to install underground infrastructure or utilities (such as gas mains, water mains or telephone lines), or later to search for these installations. Trenches have often been dug for military defensive purposes. In archaeology, the "trench method" is used for searching and excavating ancient ruins or to dig into strata of sedimented material.
Types and uses
Geology
Some trenches are created as a result of erosion by running water or by glaciers (which may have long since disappeared). Others, such as rift valleys or more commonly oceanic trenches, are created by geological movement of tectonic plates. Some oceanic trenches include the Mariana Trench and the Aleutian Trench. The former geoform is relatively deep (approximately 10 kilometres (6.2 mi)), linear and narrow, and is formed by plate subduction when plates converge.
Trenches (band)
Trenches is a Christian metal band, formed by Haste the Day vocalist, Jimmy Ryan. The band announced their hiatus in 2010 before getting back together in early 2012.
Background
Jimmy Ryan, a member of Haste the Day, at the time, decided to depart the band, when they were in Indianapolis, Indiana on December 30, 2005, doing a concert, where he is a native of the city. The group was formed, when Ryan selected Joel David Lauver to be a guitarist, keyboardist, and vocalist, Eli Larch Chastain to be a guitarist, Bill Scott to be a bassist, and Phil Hook to be their drummer.
Their first concert occurred in the city of Noblesville, Indiana, on November 24, 2007. The bands national debut was during a performance at the Cornerstone Festival, the subsequent year. Trenches was to perform, in 2009, at the same festival, yet they were replaced on the line-up listing.
Since then, Hook and Chastain have left the band, and drummer, Zach Frizzell, joined the band. The band is currently working on a new album, titled, Reckoner.
Trenches (web series)
Trenches was an American science fiction web series directed and produced by Shane Felux, creator of Star Wars: Revelations. The show premiered on Sony Pictures Entertainment owned Crackle on February 16, 2010. The show was written by Dawn Cowings and Sarah Yaworsky, and Aaron Mathias, Mercy Malick, Lev Gorn, Hong Chau, Daz Crawford, and Scott Nankivel star. New episodes were streamed on Monday, Wednesday, and Friday through March 5, 2010. Trenches was originally produced in 2007 for Disney's Stage 9, a web video venture company, but has since been licensed to Crackle.
Plot
Locked in a grueling war on a backwater planet, two enemies find themselves abandoned by their own. They must put aside their differences and work together if they are to survive. They better do it quickly - they are not alone on this rock.
