As of my last knowledge update in October 2021, I don't have information on "Jahar Saha." It's possible that it could refer to a person, concept, event, or something else that became relevant after this date or is less widely known. If you can provide more context or details, I may be able to help you better.

Los Alamos National Laboratory (LANL) is a federal research facility located in Los Alamos, New Mexico, primarily known for its role in the development of nuclear weapons during the Manhattan Project in World War II. Established in 1943, the laboratory has since evolved into a major center for scientific research and development, focusing on a wide range of fields including nuclear science, materials science, energy, bioscience, and environmental science.

Lou Bloomfield is a prominent physicist and professor at the University of Virginia, known for his work in the field of physics education and his contributions to various areas of physics research. He has authored several textbooks and resources aimed at improving understanding of physics concepts, particularly for students. In addition to his academic work, Bloomfield is known for engaging presentations and efforts to popularize physics through public lectures and outreach.

The Bernoulli umbra refers to a specific family of orthogonal polynomials known as Bernoulli polynomials, which are closely related to the study of number theory and combinatorics.

The lower shoreface is a geological term used in sedimentology and coastal processes to describe a specific zone of the coastal environment, particularly the area of the seabed that lies just below the surf zone and extends down to the offshore area. This zone typically ranges from about 3 to 10 meters (roughly 10 to 30 feet) in depth, depending on local conditions, including wave energy, sediment supply, and coastal topography.

Lucilla de Arcangelis is not widely known in prominent historical, cultural, or public contexts as of my last update in October 2021. It's possible that she is a less well-known figure, or she could be a character in a work of fiction, an artist, or someone who has gained recognition after my knowledge cutoff.

Lucy Campbell is a mathematician known for her work in the field of mathematics education, particularly in the context of teaching and learning in higher education. She has been involved in research related to pedagogy, curriculum development, and the effective use of technology in mathematics education.

Ludwig Stickelberger is known primarily for his contributions to mathematics, particularly in number theory and algebra. One of his notable contributions involves the "Stickelberger theorem," which relates to class numbers and the theory of algebraic numbers. In a broader context, Stickelberger's work often intersects with areas such as algebraic invariants and modular forms, and he has made significant contributions to the understanding of various algebraic structures.

Luigi Cremona (1830–1903) was an influential Italian mathematician, particularly known for his contributions to projective geometry. He played a key role in the development of the discipline in the late 19th century and is recognized for introducing several important concepts and methods, including the use of what are now called Cremona transformations, which are transformations in projective space.

Luigi Di Lella does not appear to be a widely recognized figure or concept in popular culture, academia, or current events, at least up until my last training data in October 2023. It's possible that he may be a private individual, a lesser-known figure in a specific field, or a fictional character.

Luis Nunes Vicente is a notable figure in the field of artificial intelligence and computer science, primarily recognized for his contributions to machine learning, natural language processing, and multimodal AI research. He is often associated with academic initiatives and collaborative projects that explore the development of advanced AI systems.

Luminosity distance is a key concept in cosmology used to relate the observed brightness of an astronomical object to its intrinsic brightness (or luminosity) while taking into account the expansion of the universe. It is defined as the distance to an object based on how much its light is spread out by the cosmic expansion and the geometry of space.

Lung compliance refers to the ability of the lungs to expand and contract in response to changes in pressure. It is a measure of the distensibility of the lung tissue and the thoracic cavity. Specifically, lung compliance is defined as the change in lung volume per unit change in pressure, typically measured in liters per centimeter of water pressure (L/cm H2O).

A Lyot filter is an optical device used in spectroscopy and imaging that employs polarization and interference to selectively transmit specific wavelengths of light while blocking others. It is named after the French physicist A.A. Lyot, who developed the technique. The basic principle behind a Lyot filter involves the use of multiple optical elements, including polarizers and birefringent crystals. These components work together to create interference effects, which enhance the transmission of certain wavelengths and suppress others.

Mabel Augusta Chase was an influential American ornithologist recognized for her contributions to the study of birds. She was particularly known for her work in the early 20th century, which included research on bird behavior and conservation. Chase also played a significant role in advancing the field of ornithology, particularly regarding the North American avifauna. In addition to her research, Mabel Augusta Chase was a member of several scientific societies and contributed to various publications within the field.

Machair is a unique type of coastal grassland found primarily in parts of Scotland and Ireland, particularly in the Hebrides and other western coastal regions. It is characterized by its fertile, sandy soil, which has been enriched by the decaying seaweed and the action of ocean waves. Machair ecosystems thrive in areas where the soil is kept moist and is often found close to the shoreline.

Madeleine Barnothy Forro is a Hungarian-American scientist renowned for her work in the field of biophysics and molecular biology. Her research has significantly contributed to the understanding of the structure and function of biological molecules.

Madhava's sine table is an ancient mathematical table created by the Indian mathematician Madhava of Sangamagrama, who lived during the late 14th and early 15th centuries. It is known for being one of the first systematic tabulations of sine values for various angles. Madhava's methodology involved calculating the sine of angles as a series expansion, similar to what we now understand as Taylor or Maclaurin series.

As of my last update in October 2021, there is no widely recognized mathematician by the name of Maggie Miller who has made significant contributions to the field that are commonly documented in public discourse. It is possible that she could be an emerging mathematician or someone who has gained recognition after that time.

Magnetic circular dichroism (MCD) is a spectroscopic technique that measures the difference in absorption of left-handed and right-handed circularly polarized light in the presence of a magnetic field. This phenomenon is commonly observed in materials that have unpaired electrons and is particularly relevant in the study of transition metal complexes, rare earth elements, and paramagnetic species.
