Oph-IRS 48 is a young stellar object located in the constellation of Ophiuchus, often identified as a protostar. It is part of a group of stars in the Ophiuchus molecular cloud complex. This region is significant for astronomical research because it provides insights into star formation processes.

The "hundred-year wave" typically refers to a concept in hydrology and civil engineering related to the statistical analysis of water level fluctuations, particularly in the context of floods. It denotes a flood event with a probability of occurring once every hundred years, also known as the "100-year flood." This measure is used to help design infrastructure, such as bridges, dams, and levees, to withstand extreme weather events.

A hybrid functional is a type of exchange-correlation functional used in density functional theory (DFT) calculations to describe the electronic structure of many-body systems, particularly atoms, molecules, and solids. In DFT, the total energy of a system is expressed as a functional of the electron density, and the exchange-correlation functional is a key component that accounts for the complex interactions between electrons.

A hydraulic manifold is a crucial component in hydraulic systems, designed to manage the flow and distribution of hydraulic fluid. It serves as a central hub that connects various hydraulic components, such as pumps, cylinders, motors, and valves, allowing for efficient control of fluid movement within the system. ### Key Functions of a Hydraulic Manifold: 1. **Fluid Distribution**: It directs hydraulic fluid to different parts of the hydraulic system according to the operational requirements.

A high-altitude balloon is a type of balloon that is designed to carry scientific instruments, technology, or payloads to the upper atmosphere, typically reaching altitudes above 20 kilometers (about 12 miles). These balloons are often filled with lighter-than-air gases, such as helium or hydrogen, allowing them to ascend to high altitudes. **Key features and uses of high-altitude balloons include:** 1.

Xu Guangqi (1562–1633) was a notable Chinese scholar, politician, and scientist during the late Ming Dynasty. He is best known for his contributions to the introduction of Western science and technology in China. Xu was a key figure in the Ming Dynasty's efforts to assimilate Western knowledge, particularly through his collaboration with the Italian Jesuit missionary Matteo Ricci. Xu Guangqi was particularly interested in agricultural science and is credited with promoting the adoption of new agricultural techniques and tools.

Zinc finger protein 839 (ZNF839) is a member of the zinc finger protein family, which plays diverse roles in cellular processes, including DNA binding, transcription regulation, and protein-protein interactions. Zinc finger proteins are characterized by the presence of one or more zinc finger motifs, which are small protein structural motifs that coordinate zinc ions to stabilize their folds.

The Association for Women in Mathematics (AWM) is a non-profit organization dedicated to promoting the participation of women and girls in mathematics. Founded in 1971, AWM advocates for the advancement of women in the field of mathematics through a variety of initiatives, including educational programs, mentorship, networking opportunities, and support for research. AWM organizes meetings, conferences, and workshops that emphasize collaboration and provide a platform for women mathematicians to share their work and experiences.
