Space diagonalIn geometry, a space diagonal (also interior diagonal or body diagonal) of a polyhedron is a line connecting two vertices that are not on the same face. Space diagonals contrast with face diagonals, which connect vertices on the same face (but not on the same edge) as each other. For example, a pyramid has no space diagonals, while a cube (shown at right) or more generally a parallelepiped has four space diagonals. An axial diagonal is a space diagonal that passes through the center of a polyhedron.
Stiefel–Whitney classIn mathematics, in particular in algebraic topology and differential geometry, the Stiefel–Whitney classes are a set of topological invariants of a real vector bundle that describe the obstructions to constructing everywhere independent sets of sections of the vector bundle. Stiefel–Whitney classes are indexed from 0 to n, where n is the rank of the vector bundle. If the Stiefel–Whitney class of index i is nonzero, then there cannot exist everywhere linearly independent sections of the vector bundle.
Electronic health recordAn electronic health record (EHR) is the systematized collection of patient and population electronically stored health information in a digital format. These records can be shared across different health care settings. Records are shared through network-connected, enterprise-wide information systems or other information networks and exchanges. EHRs may include a range of data, including demographics, medical history, medication and allergies, immunization status, laboratory test results, radiology images, vital signs, personal statistics like age and weight, and billing information.
DALL-EDALL-E (stylized as DALL·E) and DALL-E 2 are s developed by OpenAI using deep learning methodologies to generate s from natural language descriptions, called "prompts". DALL-E was revealed by OpenAI in a blog post in January 2021, and uses a version of GPT-3 modified to generate images. In April 2022, OpenAI announced DALL-E 2, a successor designed to generate more realistic images at higher resolutions that "can combine concepts, attributes, and styles". OpenAI has not released source code for either model.
Green politicsGreen politics, or ecopolitics, is a political ideology that aims to foster an ecologically sustainable society often, but not always, rooted in environmentalism, nonviolence, social justice and grassroots democracy. It began taking shape in the western world in the 1970s; since then green parties have developed and established themselves in many countries around the globe and have achieved some electoral success. The political term green was used initially in relation to die Grünen (German for "the Greens"), a green party formed in the late 1970s.
Green partyA green party is a formally organized political party based on the principles of green politics, such as social justice, environmentalism and nonviolence. Green party platforms typically embrace social democratic economic policies and form coalitions with other left-wing parties. Green parties exist in nearly 90 countries around the world, many of which are members of Global Greens. There are distinctions between "green" parties and "Green" parties. Any party, faction, or politician may be labeled "green" if it emphasizes environmental causes.
Red–green allianceIn politics, a red–green alliance or red–green coalition is an alliance of "red" (often social-democratic or democratic socialist) parties with "green" (often green and/or occasionally agrarian) parties. The alliance is often based on common left political views, especially a shared distrust of corporate or capitalist institutions. While the "red" social-democratic parties tend to focus on the effects of capitalism on the working class, the "green" environmentalist parties tend to focus on the environmental effects of capitalism.
GreenGreen is the color between cyan and yellow on the visible spectrum. It is evoked by light which has a dominant wavelength of roughly 495570 nm. In subtractive color systems, used in painting and color printing, it is created by a combination of yellow and cyan; in the RGB color model, used on television and computer screens, it is one of the additive primary colors, along with red and blue, which are mixed in different combinations to create all other colors.
