Reflection (Demis Roussos album)

Reflection is an album released in 1984 by Demis Roussos.

After having collaborated several times since the days of Aphrodite's Child, Reflection was the last album on which Roussos and Vangelis collaborated. Another member from that band, guitarist Argyris 'Silver' Koulouris, also appears on this album. Vangelis’ habitual collaborators, jazz saxophonist Dick Morrissey, and vocalists Carol Kenyon and Tessa Niles also appear.

Reflection (computer programming)

In computer science, reflection is the ability of a computer program to examine (see type introspection) and modify its own structure and behavior (specifically the values, meta-data, properties and functions) at runtime.

Historical background

The earliest computers were programmed in their native assembly language, which were inherently reflective as these original architectures could be programmed by defining instructions as data and using self-modifying code. As programming moved to higher-level languages such as C, this reflective ability disappeared (outside of malware) until programming languages with reflection built into their type systems appeared.

Brian Cantwell Smith's 1982 doctoral dissertation introduced the notion of computational reflection in programming languages, and the notion of the meta-circular interpreter as a component of 3-Lisp.

Uses

Reflection can be used for observing and modifying program execution at runtime. A reflection-oriented program component can monitor the execution of an enclosure of code and can modify itself according to a desired goal related to that enclosure. This is typically accomplished by dynamically assigning program code at runtime.

Surgical suture

Surgical suture (commonly called stitches) is a medical device used to hold body tissues together after an injury or surgery. Application generally involves using a needle with an attached length of thread. A number of different shapes, sizes, and thread materials have been developed over its millennia of history. Surgeons, physicians, dentists, podiatrists, eye doctors, registered nurses and other trained nursing personnel, medics, and clinical pharmacists typically engage in suturing. Surgical knots are used to secure the sutures.

History

Through many millennia, various suture materials were used, debated, and remained largely unchanged. Needles were made of bone or metals such as silver, copper, and aluminium bronze wire. Sutures were made of plant materials (flax, hemp and cotton) or animal material (hair, tendons, arteries, muscle strips and nerves, silk, and catgut).

The earliest reports of surgical suture date to 3000 BC in ancient Egypt, and the oldest known suture is in a mummy from 1100 BC. A detailed description of a wound suture and the suture materials used in it is by the Indian sage and physician Sushruta, written in 500 BC. The Greek father of medicine, Hippocrates, described suture techniques, as did the later Roman Aulus Cornelius Celsus. The 2nd-century Roman physician Galen described gut sutures. In the 10th century the manufacturing process involved harvesting sheep intestines, the so-called catgut suture, and was similar to that of strings for violins, guitar, and tennis racquets.

Sabre

Sabre I

The first Sabre was a former knife thrower named Paul Richarde until he was selected by Modred to oppose Black Knight. Paul Richarde was given an armor, an animated gargoyle. and Mordred's Ebony Dagger (the weapon with which Mordred had killed the first Black Knight). He was defeated by Black Knight after his horse Aragorn kicked the dagger from Le Sabre's hand.

Sabre II

The second Sabre is a mutant super villain. His first appearance was in X-Men #106. Young and reckless, Sabre was chosen by Mystique to join her new Brotherhood of Mutants, though never actually participated in any missions. He had the mutant ability of super speed, and took the name of the deceased Super Sabre. It is unknown if he continues to serve Mystique behind the scenes, or if he even retains his powers after Decimation. Hyper-accelerated metabolism augments his natural speed, reflexes, coordination, endurance, and the healing properties of his body.
