CMS Pipelines implements the pipeline concept under the VM/CMS operating system. The programs in a pipeline operate on a sequential stream of records. A program writes records that are read by the next program in the pipeline. Any program can be combined with any other because reading and writing is done through a device independent interface.

The Hispanic paradox is an epidemiological finding that Hispanic Americans tend to have health outcomes that "paradoxically" are comparable to, or in some cases better than, those of their U.S. non-Hispanic White counterparts, even though Hispanics have lower average income and education. Low socioeconomic status is almost universally associated with worse population health and higher death rates everywhere in the world. The paradox usually refers in particular to low mortality among Hispanics in the United States relative to non-Hispanic Whites. According to the Center for Disease Control's 2015 Vital Signs report, Hispanics in the United States had a 24% lower risk of mortality, as well as lower risk for nine of the fifteen leading causes of death as compared to Whites.

There are multiple hypotheses which aim to determine the reason for the existence of this paradox. Some attribute the Hispanic paradox to biases created by patterns or selection in migration. One such hypothesis is the Salmon Bias, which suggests that Hispanics tend to return home towards the end of their lives, ultimately rendering an individual "statistically immortal" and thus artificially lowering mortality for Hispanics in the United States. Another hypothesis in this group is that of the Healthy Migrant, which attributes the better health of Hispanics to the assumption that the healthiest and strongest members of a population are most likely to migrate.

Other hypotheses around the Hispanic paradox maintain that the phenomenon is real, and is caused by sociocultural factors which characterize the Hispanic population. Many of these factors can be described under the more broad categories of cultural values, interpersonal context, and community context. Some health researchers attribute the Hispanic paradox to different eating habits, especially the relatively high intake of legumes such as beans and lentils.

A toroidal propeller is a type of propeller that is ring-shaped with each blade forming a closed loop. The propellers are significantly quieter at audible frequency ranges, between 20 Hz and 20 kHz, while generating comparable thrust to traditional propellers. In practice, toroidal propellers reduce noise pollution in both aviation and maritime transport.

An amygdala hijack refers to a personal, emotional response that is immediate, overwhelming, and out of measure with the actual stimulus because it has triggered a much more significant emotional threat. The term was coined by Daniel Goleman in his 1996 book Emotional Intelligence: Why It Can Matter More Than IQ.

🔗 Computing 🔗 Computing/Amiga

The Smart File System (SFS) is a journaling filesystem used on Amiga computers and AmigaOS-derived operating systems (though some support also exists for IBM PC compatibles). It is designed for performance, scalability and integrity, offering improvements over standard Amiga filesystems as well as some special or unique features.

Lanai (Hawaiian: Lānaʻi, Hawaiian: [laːˈnɐʔi, naːˈnɐʔi], lə-NY, lah-NAH-ee, also US: lah-NY, lə-NAH-ee,) is the sixth-largest of the Hawaiian Islands and the smallest publicly accessible inhabited island in the chain. It is colloquially known as the Pineapple Island because of its past as an island-wide pineapple plantation. The island's only settlement of note is the small town of Lanai City. As of 2012, the island is 98% owned by Larry Ellison, cofounder and chairman of Oracle Corporation; the remaining 2% is owned by the state of Hawaii or individual homeowners.

Lanai is a roughly apostrophe-shaped island with a width of 18 miles (29 km) in the longest direction. The land area is 140.5 square miles (364 km²), making it the 43rd largest island in the United States. It is separated from the island of Molokaʻi by the Kalohi Channel to the north, and from Maui by the Auʻau Channel to the east. The United States Census Bureau defines Lanai as Census Tract 316 of Maui County. Its total population rose to 3,367 as of the 2020 United States census, up from 3,193 as of the 2000 census and 3,131 as of the 2010 census. As visible via satellite imagery, many of the island's landmarks are accessible only by dirt roads that require a four-wheel drive vehicle due to the lack of paved roadways.

There is one school, Lanai High and Elementary School, serving the entire island from kindergarten through 12th grade. There is also one hospital, Lanai Community Hospital, with 24 beds, and a community health center providing primary care, dental, behavioral health and selected specialty services in Lanai City. There are no traffic lights on the island.

The "gay bomb" and "halitosis bomb" are formal names for two non-lethal psychochemical weapons that a United States Air Force research laboratory speculated about producing. The theories involve discharging female sex pheromones over enemy forces in order to make them sexually attracted to each other.

In 1994 the Wright Laboratory in Ohio, a predecessor to today's United States Air Force Research Laboratory, produced a three-page proposal on a variety of possible nonlethal chemical weapons, which was later obtained by the Sunshine Project through a Freedom of Information Act request.

Katarina Vilioni (died 1342) was one of the first Europeans known to have resided in China. She was apparently a member of a Genoese trading family that lived in Yangzhou during the mid-14th century.

Vilioni is known through her tombstone, which was rediscovered at Yangzhou in 1951. It suggests that Vilioni died in 1342 and was the daughter of a man named Domenico Vilioni.

🔗 Computer science

The General Purpose Analog Computer (GPAC) is a mathematical model of analog computers first introduced in 1941 by Claude Shannon. This model consists of circuits where several basic units are interconnected in order to compute some function. The GPAC can be implemented in practice through the use of mechanical devices or analog electronics. Although analog computers have fallen almost into oblivion due to emergence of the digital computer, the GPAC has recently been studied as a way to provide evidence for the physical Church–Turing thesis. This is because the GPAC is also known to model a large class of dynamical systems defined with ordinary differential equations, which appear frequently in the context of physics. In particular it was shown in 2007 that (a deterministic variant of) the GPAC is equivalent, in computability terms, to Turing machines, thereby proving the physical Church–Turing thesis for the class of systems modelled by the GPAC. This was recently strengthened to polynomial time equivalence.

The Saturn family of 4-bit (datapath) microprocessors was developed by Hewlett-Packard in the 1980s first for the HP-71B handheld computer and then later for various HP calculators (starting with the HP-18C). It succeeded the Nut family of processors used in earlier calculators. The original Saturn chip was first used in the HP-71B hand-held BASIC-programmable computer, introduced in 1984. Later models of the family powered the popular HP 48 series of calculators. The HP48SX and HP48S were the last models to use genuine Saturn processors manufactured by HP. Later calculator models used Saturn processors manufactured by NEC. The HP 49 series initially used the Saturn CPU as well, until the NEC fab could no longer manufacture the processor for technical reasons in 2003. Therefore, starting with the HP 49g+ model in 2003, the calculators switched to a Samsung S3C2410 processor with an ARM920T core (part of the ARMv4T architecture) which ran an emulator of the Saturn hardware in software. In 2000, the HP 39G and HP 40G were the last calculators introduced based on the actual NEC fabricated Saturn hardware. The last calculators based on the Saturn emulator were the HP 39gs, HP 40gs and HP 50g in 2006, as well as the 2007 revision of the hp 48gII. The HP 50g, the last calculator utilizing this emulator, was discontinued in 2015 when Samsung stopped producing the ARM processor on which it was based.
