Picture Bride
The term picture bride refers to the practice in the early 20th century of immigrant workers (chiefly Japan ese, Okinawan, and Korean) in Hawaii and the West Coast of the United States and Canada selecting brides from their native countries via a matchmaker, who paired bride and groom using only photographs and family recommendations of the possible candidates. This is an abbreviated form of the traditional matchmaking process and is similar in a number of ways to the concept of the mail-order bride.

William Thomson, Baron Kelvin
William Thomson, Baron Kelvin, OM, GCVO, PC, PRS, FRSE (26 June 1824 – 17 December 1907) was a British[1] mathematical physicist and engineer who was born in Belfast in 1824. At the University of Glasgow he did important work in the mathematical analysis of electricity and formulation of the first and second laws of thermodynamics, and did much to unify the emerging discipline of physics in it

Mir-137
In molecular biology, miR-137 (or microRNA-137) is a short non-coding RNA molecule that functions to regulate the expression levels of other genes by various mechanisms. miR-137 is located on human chromosome 1p22 and has been implicated to act as a tumor suppressor in several cancer types including colorectal cancer, squamous cell carcinoma and melanoma via cell cycle control. Recent genome-wide association studies (GWAS) have provided evidence to suggest that single nucleotide polymorphisms in the vicinity of the MIR137 gene are statistically associated with schizophrenia and other psychiatric disorders. miR-137 is shown to regulate neural stem cell proliferation and differentiation in mouse embryonic stem cells, and neuronal maturation, including regulation of dendrite length, branch points, end points, and spine density in mouse adult hippocampal neuroprogenitor-derived and mouse fetal hippocampus neurons. Decreased spine density has also been observed in the dorsolateral cortex of patients with schizophrenia. miR-137 belongs to the miR-137 clan (a clan is group of two or more RNA families that have arisen from a single evolutionary origin, as derived from their related structure and function). The miR-137 clan contains two members: miR-137 and miR-234; the total number of RNA domains in the clan is 112.

Liberal Socialism
Liberal socialism is a socialist political philosophy that incorporates liberal principles. Liberal socialism does not have the goal of completely abolishing capitalism and replacing it with socialism, but it instead supports a mixed economy that includes both private property and social ownership in capital goods. Although liberal socialism unequivocally favors a mixed market economy, it identifies legalistic and artificial monopolies to be the fault of capitalism and opposes an entirely unregulated economy. It considers both liberty and equality to be compatible and mutually dependent on each other. Principles that can be described as liberal socialist are based on the works of philosophers such as John Stuart Mill, Eduard Bernstein, John Dewey, Carlo Rosselli, Norberto Bobbio, Chantal Mouffe and Karl Polanyi. Other important liberal socialist figures include Guido Calogero, Piero Gobetti, Leonard Hobhouse, John Maynard Keynes and R. H. Tawney. To Polanyi, liberal socialism's goal was overcoming exploitative aspects of capitalism by expropriation of landlords and opening to all the opportunity to own land. Liberal socialism has been particularly prominent in British and Italian politics. Liberal socialism’s seminal ideas can be traced to John Stuart Mill, who theorised that capitalist societies should experience a gradual process of socialisation through worker-controlled enterprises, coexisting with private enterprises. Mill rejected centralised models of socialism that could discourage competition and creativity, but he argued that representation is essential in a free government and democracy could not subsist if economic opportunities were not well distributed, therefore conceiving democracy not just as form of representative government, but as an entire social organisation.

High Entropy Alloys
High-entropy alloys (HEAs) are alloys that are formed by mixing equal or relatively large proportions of (usually) five or more elements. Prior to the synthesis of these substances, typical metal alloys comprised one or two major components with smaller amounts of other elements. For example, additional elements can be added to iron to improve its properties, thereby creating an iron based alloy, but typically in fairly low proportions, such as the proportions of carbon, manganese, and the like in various steels. Hence, high entropy alloys are a novel class of materials. The term “high-entropy alloys” was coined because the entropy increase of mixing is substantially higher when there is a larger number of elements in the mix, and their proportions are more nearly equal. These alloys are currently the focus of significant attention in materials science and engineering because they have potentially desirable properties. Furthermore, research indicates that some HEAs have considerably better strength-to-weight ratios, with a higher degree of fracture resistance, tensile strength, as well as corrosion and oxidation resistance than conventional alloys. Although HEAs have been studied since the 1980s, research substantially accelerated in the 2010s.

Glossolalia
Glossolalia or speaking in tongues is a phenomenon in which people speak words that are apparently in languages unknown to the speaker. One definition used by linguists is the fluid vocalizing of speech-like syllables that lack any readily comprehended meaning, in some cases as part of religious practice in which it is believed to be a divine language unknown to the speaker. Glossolalia is practiced in Pentecostal and charismatic Christianity as well as in other religions. Sometimes a distinction is made between "glossolalia" and "xenolalia" or "xenoglossy", which specifically designates when the language being spoken is a natural language previously unknown to the speaker. This distinction is not universally made, and the New Testament of the Bible mentions the phenomenon in at least one passage in reference to speaking in languages known to others but not to the speakers.
