International Adoption
International adoption (also referred to as intercountry adoption or transnational adoption) is a type of adoption in which an individual or couple becomes the legal and permanent parent(s) of a child who is a national of a different country. In general, prospective adoptive parents must meet the legal adoption requirements of their country of residence and those of the country whose nationality the child holds. International adoption is not the same thing as transcultural or interracial adoption. However, the fact is that a family will often become a transcultural or interracial family upon the adoption of a child internationally. The laws of countries vary in their willingness to allow international adoptions. Some countries have established rules and procedures for international adoptions, while other countries expressly forbid it. Various countries, notably many African nations, have extended residency requirements for adoptive parents that, in effect, rule out most international adoptions.

Relevance (Law)
Relevance, in the common law of evidence, is the tendency of a given item of evidence to prove or disprove one of the legal elements of the case, or to have probative value to make one of the elements of the case likelier or not. Probative is a term used in law to signify "tending to prove." Probative evidence "seeks the truth". Generally in law, evidence that is not probative (doesn't tend to prove the proposition for which it is proffered) is inadmissible and the rules of evidence permit it to be excluded from a proceeding or stricken from the record "if objected to by opposing counsel." A balancing test may come into the picture if the value of the evidence needs to be weighed versus its prejudicial nature.

Fundamental Interaction
In physics, the fundamental interactions, also known as fundamental forces, are the interactions that do not appear to be reducible to more basic interactions. There are four fundamental interactions known to exist: the gravitational and electromagnetic interactions, which produce significant long-range forces whose effects can be seen directly in everyday life, and the strong and weak interactions, which produce forces at minuscule, subatomic distances and govern nuclear interactions. Some scientists hypothesize that a fifth force might exist, but these hypotheses remain speculative. Each of the known fundamental interactions can be described mathematically as a field. The gravitational force is attributed to the curvature of spacetime, described by Einstein's general theory of relativity. The other three are discrete quantum fields, and their interactions are mediated by elementary particles described by the Standard Model of particle physics. Within the Standard Model, the strong interaction is carried by a particle called the gluon, and is responsible for quarks binding together to form hadrons, such as protons and neutrons. As a residual effect, it creates the nuclear force that binds the latter particles to form atomic nuclei. The weak interaction is carried by particles called W and Z bosons, and also acts on the nucleus of atoms, mediating radioactive decay. The electromagnetic force, carried by the photon, creates electric and magnetic fields, which are responsible for the attraction between orbital electrons and atomic nuclei which holds atoms together, as well as chemical bonding and electromagnetic waves, including visible light, and forms the basis for electrical technology. Although the electromagnetic force is far stronger than gravity, it tends to cancel itself out within large objects, so over large (astronomical) distances gravity tends to be the dominant force, and is responsible for holding together the large scale structures in the universe, such as planets, stars, and galaxies. Many theoretical physicists believe these fundamental forces to be related and to become unified into a single force at very high energies on a minuscule scale, the Planck scale, but particle accelerators cannot produce the enormous energies required to experimentally probe this. Devising a common theoretical framework that would explain the relation between the forces in a single theory is perhaps the greatest goal of today's theoretical physicists. The weak and electromagnetic forces have already been unified with the electroweak theory of Sheldon Glashow, Abdus Salam, and Steven Weinberg for which they received the 1979 Nobel Prize in physics. Some physicists seek to unite the electroweak and strong fields within what is called a Grand Unified Theory (GUT). An even bigger challenge is to find a way to quantize the gravitational field, resulting in a theory of quantum gravity (QG) which would unite gravity in a common theoretical framework with the other three forces. Some theories, notably string theory, seek both QG and GUT within one framework, unifying all four fundamental interactions along with mass generation within a theory of everything (ToE).

Doctor of Osteopathic Medicine
Doctor of Osteopathic Medicine (DO or D.O., or in Australia DO USA) is a medical degree conferred by the 38 osteopathic medical schools in the United States. DO and Doctor of Medicine (MD) degrees are equivalent: a DO graduate may become licensed as a physician and thus have full medical and surgical practicing rights in all 50 US states. (As of 2021), there were 168,701 osteopathic physicians and medical students in DO programs across the United States. Osteopathic medicine emerged historically from osteopathy, but has become a distinct profession. (As of 2014), more than 28% of all US medical students were DO students. The curricula at DO-granting medical schools are equivalent to those at MD-granting medical schools, which focus the first two years on the biomedical and clinical sciences, then two years on core clinical training in the clinical specialties. One notable difference between DO and MD training is that DOs spend an additional 300–500 hours to study a set of hands-on manipulation (OMT) of the human musculoskeletal system along with learning conventional Western medicine and surgery like their MD peers. Upon completing osteopathic medical school, a DO graduate may enter an internship or residency training program, which may be followed by fellowship training. DO graduates attend the same graduate medical education programs as their MD counterparts.
