In markup languages and the digital humanities, overlap occurs when a document has two or more structures that interact in a non-hierarchical manner. A document with overlapping markup cannot be represented as a tree. This is also known as concurrent markup. Overlap happens, for instance, in poetry, where there may be a metrical structure of feet and lines; a linguistic structure of sentences and quotations; and a physical structure of volumes and pages and editorial annotations.

Carpets of Middle-Eastern origin, either from Anatolia, Persia, Armenia, Azerbaijan, the Levant, the Mamluk state of Egypt or Northern Africa, were used as decorative features in Western European paintings from the 14th century onwards. More depictions of Oriental carpets in Renaissance painting survive than actual carpets contemporary with these paintings. Few Middle-Eastern carpets produced before the 17th century remain, though the number of these known has increased in recent decades. Therefore, comparative art-historical research has from its onset in the late 19th century relied on carpets represented in datable European paintings.

The Rule 110 cellular automaton (often simply Rule 110) is an elementary cellular automaton with interesting behavior on the boundary between stability and chaos. In this respect, it is similar to Conway's Game of Life. Like Life, Rule 110 is known to be Turing complete. This implies that, in principle, any calculation or computer program can be simulated using this automaton.

Yuri Alekseyevich Gagarin  (9 March 1934 – 27 March 1968) was a Soviet Air Forces pilot and cosmonaut who became the first human to journey into outer space, achieving a major milestone in the Space Race; his capsule Vostok 1 completed one orbit of Earth on 12 April 1961. Gagarin became an international celebrity and was awarded many medals and titles, including Hero of the Soviet Union, his nation's highest honour.

Born in the village of Klushino near Gzhatsk (a town later renamed after him), in his youth Gagarin was a foundryman at a steel plant in Lyubertsy. He later joined the Soviet Air Forces as a pilot and was stationed at the Luostari Air Base, near the Norwegian border, before his selection for the Soviet space programme with five other cosmonauts. Following his spaceflight, Gagarin became deputy training director of the Cosmonaut Training Centre, which was later named after him. He was also elected as a deputy of the Soviet of the Union in 1962 and then to the Soviet of Nationalities, respectively the lower and upper chambers of the Supreme Soviet.

Vostok 1 was Gagarin's only spaceflight but he served as the backup crew to the Soyuz 1 mission, which ended in a fatal crash, killing his friend and fellow cosmonaut Vladimir Komarov. Fearing for his life, Soviet officials permanently banned Gagarin from further spaceflights. After completing training at the Zhukovsky Air Force Engineering Academy on 17 February 1968, he was allowed to fly regular aircraft. Gagarin died five weeks later when the MiG-15 training jet he was piloting with his flight instructor Vladimir Seryogin crashed near the town of Kirzhach.

SuperH (or SH) is a 32-bit reduced instruction set computing (RISC) instruction set architecture (ISA) developed by Hitachi and currently produced by Renesas. It is implemented by microcontrollers and microprocessors for embedded systems.

At the time of introduction, SuperH was notable for having fixed-length 16-bit instructions in spite of its 32-bit architecture. This was a novel approach; at the time, RISC processors always used an instruction size that was the same as the internal data width, typically 32-bits. Using smaller instructions had consequences, the register file was smaller and instructions were generally two-operand format. But for the market the SuperH was aimed at, this was a small price to pay for the improved memory and processor cache efficiency.

Later versions of the design, starting with SH-5, included both 16- and 32-bit instructions, with the 16-bit versions mapping onto the 32-bit version inside the CPU. This allowed the machine code to continue using the shorter instructions to save memory, while not demanding the amount of instruction decoding logic needed if they were completely separate instructions. This concept is now known as a compressed instruction set and is also used by other companies, the most notable example being ARM for its Thumb instruction set.

As of 2015, many of the original patents for the SuperH architecture are expiring and the SH-2 CPU has been reimplemented as open source hardware under the name J2.

🔗 Television 🔗 Star Trek

Star Trek: Phase II was the initial working title for what officially became titled Star Trek II, an unproduced American science fiction television series created by Gene Roddenberry as a sequel to (and continuation of) the original Star Trek, which had run from 1966 to 1969. The plans for the series were first developed after several failed attempts to create a feature film based on the property, coupled with plans for a Paramount Television Service (PTS) as a fourth broadcast television network in the United States.

Both PTS and the Star Trek revival were announced in early June 1977, with PTS to debut as one evening of programming each Saturday night and to gradually expand to other nights; a strategy successfully employed by the Fox Broadcasting Company a decade later. Star Trek: Phase II was to be the flagship show, and be broadcast at 8pm EST, followed by a movie of the week starting at 9pm. The initial order was for a two-hour pilot, followed by 13 hour-long episodes.

With the exception of Leonard Nimoy as Mr. Spock, who had ongoing disputes with Roddenberry and Paramount, the entire regular and recurring cast of The Original Series were contracted to return, notably William Shatner as Captain Kirk. Three new and younger regular characters were created, science officer Lt. Xon, navigator Lt. Ilia, and ship's executive officer Willard Decker. Xon, Decker and Ilia were later influential in the development of characters on Star Trek: The Next Generation, and two of the scripts written for Phase II would be re-developed for use in that series.

Behind the cameras, Roddenberry recruited Trek-novices Harold Livingston and Robert Goodwin as producers. Veterans of The Original Series were few, and included costume designer William Ware Theiss and illustrator Mike Minor. Art director Matt Jefferies was otherwise employed and brought in as a "technical advisor" and to update the design of the starship USS Enterprise. Special effects (on set) were to be by Jim Rugg. Science fiction novelist Alan Dean Foster received the assignment to write the story outline for the two-hour pilot, but, with a looming production deadline and unable to find a suitable writer to develop this story into a teleplay, Harold Livingston took on the writing job himself. Of the remaining 12 script assignments handed out, about half were to veterans of The Original Series.

Pre-production began in earnest, with the emphasis on what would be the standing sets of the Enterprise, which differed radically in layout, design and detailing from those for The Original Series. Many costumes and props, too, were designed. Ultimately, Paramount's plans for its network and Star Trek's TV return faltered, as the low anticipated advertising revenues for the Paramount Television Service indicated that it was not viable, and the Paramount Pictures parent company Gulf and Western's chairman, Charles Bluhdorn, refused to back the plan, resulting in the eventual exit of Paramount chief executive officer Barry Diller. In August 1977 Paramount president Michael Eisner announced—internally—that the two-hour pilot script was to be the long sought-after feature film story. However, In order to prevent negative publicity, the "cancellation" of the series and network was not immediately disclosed and development of the series and its scripts continued for a further five months, during which time tests were filmed on the incomplete Enterprise sets in widescreen format - a clear indication that whatever Star Trek would be, it would not be a TV movie.

On March 28, 1978, any illusions that Star Trek would be returning to television were ended when Paramount announced that instead of a series it would be producing what became the big budget film titled Star Trek: The Motion Picture (1979), which was itself a massive reworking of the "In Thy Image" two-hour pilot script.

Preproduction work on the series did not entirely go to waste. The standing Enterprise sets would be extensively reworked for the film (and its eventual sequels), and an unfinished admiral's office set's walls became part of the Enterprise cargo deck. However, the visual effects people hired for the feature film decided that the miniatures under construction were not up to the standards of a post-Star Wars feature, and all were scrapped. Director Robert Collins, who had been hired to direct the pilot, and promised he was to direct the feature, was replaced by Robert Wise.

The concept of a "Paramount Network" led by a flagship Star Trek series finally came to fruition in January 1995 when Paramount launched the United Paramount Network (UPN) and the Star Trek: Voyager series.

The axial twist theory (a.k.a. axial twist hypothesis) is a proposed scientific theory to explain a range of unusual aspects of the body plan of vertebrates (including humans). It states that the rostral part of the head is "turned around" regarding the rest of the body. This end-part consists of the face (eyes, nose, and mouth) as well as part of the brain (cerebrum and thalamus). According to the theory, the vertebrate body has a left-handed chirality.

The axial twist theory competes with a number of other proposals that focus on more limited, specific aspects, most of which explain contralateral forebrain organization, the phenomenon that the left side of the brain mainly controls the right side of the body and vice versa. None of the proposed theories explaining this phenomenon, including axial twist theory, have gained general recognition. The genetic basis underlying the proposed developmental twist is not yet understood.

The axial twist theory would explain various anatomical phenomena, and addresses how and when the proposed twist between the end of the head and the rest of the body develops. It also addresses the possible evolutionary history. One prediction of the theory was the aurofacial asymmetry, which was then found empirically, albeit by one of the authors of the original theory.

Phenomena the theory can explain include:

• Contralateral organization of the brain
• Left-sided orientation of the heart
• Asymmetric position of the gastrointestinal tract, the liver, and the pancreas
• Optic chiasm
• Chiasm of the trochlear nerve
• Non-crossed olfactory tract
• Aurofacial asymmetry
• Yakovlevian torque
• Asymmetry of the thoracal vertebra

According to the axial twist developmental model, the anterior part of the head turns against the rest of the body, except for the inner organs. Due to this twist, the forebrain and face are turned around such that left and right, but also anterior and posterior are flipped in the adult vertebrate.

Zombie Zero is an attack vector where a cyber attacker utilized malware that was clandestinely embedded in new barcode readers which were manufactured overseas.

It remains unknown if this attack was promulgated by organized crime or a nation state. Clearly there was significant planning and investment in order to design the malware, and then embed it into the hardware within the barcode scanner. Internet of things (IoT) devices may be similarly preinstalled with malware that can capture the network passwords and then open a backdoor to attackers. Given the high volume of these devices manufactured overseas high caution is to be exercised before placing these devices on corporate or government networks.
