Mesh

A mesh is a barrier made of connected strands of metal, fiber, or other flexible/ductile materials. A mesh is similar to a web or a net in that it has many attached or woven strands.

Types of mesh

Partition of an interval

In mathematics, a partition of an interval [a, b] on the real line is a finite sequence x = ( x_i ) of real numbers such that

In other terms, a partition of a compact interval I is a strictly increasing sequence of numbers (belonging to the interval I itself) starting from the initial point of I and arriving at the final point of I.

Every interval of the form [x_i, x_i+1] is referred to as a sub-interval of the partition x.

Refinement of a partition

Another partition of the given interval, Q, is defined as a refinement of the partition, P, when it contains all the points of P and possibly some other points as well; the partition Q is said to be “finer” than P. Given two partitions, P and Q, one can always form their common refinement, denoted P ∨ Q, which consists of all the points of P and Q, re-numbered in order.

Norm of a partition

The norm (or mesh) of the partition

is the length of the longest of these subintervals, that is

Applications

Partitions are used in the theory of the Riemann integral, the Riemann–Stieltjes integral and the regulated integral. Specifically, as finer partitions of a given interval are considered, their mesh approaches zero and the Riemann sum based on a given partition approaches the Riemann integral.

Meš

The cuneiform MEŠ, or meš is a plural form attached at the end of Mesopotamian cuneiform words as a suffix. As part of a name (PN, personal name, or other), or major class being referenced, in capital letters (a sumerogram form), it is typically separated from other capital letter sumerograms with a period. The name of the group can follow, in lower case letters, for example: (men-massu, Amarna letter EA 365), LÚ.MEŠ–ma-as-sà-meš, (and using a secondary suffix meš, not being typical).

The MEŠ cuneiform is a vertical stroke, followed by three or four angled smaller wedge-strokes. The strokes can also be "not angled", but 45 degree wedges, smaller, or large. For example, Amarna letter EA 161, Aziru to Pharaoh, shows a series of six preparation items listed sequentially. The following wedges (on the meš or sumerogram .MEŠ wedges, are large, and the scribe has a scribing base line, that follows the vertical stroke, a baseline on which the wedges are placed sequentially. EA 161 shows the baseline 'remainder', extending beyond the last 3rd, or 4th wedge.

Squid

Squid are cephalopods of the order Teuthida, which comprises around 304 species. Like all other cephalopods, squid have a distinct head, bilateral symmetry, a mantle, and arms. Squid, like cuttlefish, have eight arms arranged in pairs and two, usually longer, tentacles. Squid are strong swimmers and certain species can "fly" for short distances out of the water.

Taxonomy

Squid are members of the class Cephalopoda, subclass Coleoidea, order Teuthida, which has two major suborders, Myopsina and Oegopsina (including giant squid such as Architeuthis dux). Teuthida is the largest cephalopod order with around 300 species classified into 29 families.

The order Teuthida is a member of the superorder Decapodiformes (from the Greek for "ten legs"). Two other orders of decapodiform cephalopods are also called squid, although they are taxonomically distinct from Teuthida and differ recognizably in their gross anatomical features. They are the bobtail squid of order Sepiolida and the ram's horn squid of the monotypic order Spirulida. The vampire squid, however, is more closely related to the octopuses than to any squid.

Squid (Marvel Comics)

Squid is the name of four Marvel Comics villains.

Fictional character biography

Namor foe

The first villain called The Squid battled Namor in the 1940s.

Scungili family

The second Squid was a gangster and youngest member of the Scungili Crime Family who battled Spider-Woman.

The School

The third Squid is the leader of The School (which also consisted of Crab, Minnow, Mussels, Seahorse, and Seaweed) who had fought Namorita.

Don Callahan

The fourth villain to take up the name was Don Callahan. After his mother died, Don had a hard time relating to his father "Big Mike" Callahan. He eventually fell into the wrong crowd and ended up transformed into a mouthless squid-like creature. In his first outing as a supervillain, Squid and his girlfriend Ms. Fortune battled Spider-Man on a rooftop. Spider-Man defeated them.

After their failure, the ones responsible for Squid's creation attacked him and Ms. Fortune (who barely survived). She broke up with Squid. Squid was later hired by an unnamed Upper West Side crime boss to eliminate the local businessmen that won't sell their properties to him. Squid later dragged a cigar store owner named "Old Man" Frenzetti into the sewers and later killed him. He later confronted his father at a bar and then stormed out as Peter Parker entered. Squid later came up through the sink pipes of Miguel Vargas' coffee shop in an attempt to kill him. Miguel escaped as Mike Callahan attacked him with a baseball bat. Squid broke the bat, but was blindsided by Spider-Man. Both Spider-Man and Mike managed to calm Squid down with Mike telling his son his apology for the way he treated him. After a long talk in the night, Squid was presumably taken away by the police.
