Spatial interference from well-separated condensates [PDF]
, 2010 We use magnetic levitation and a variable-separation dual optical plug to obtain clear spatial interference between two condensates axially separated by up to 0.25 mm -- the largest separation observed with this kind of interferometer.

Atmosphere, 2022 Observations of the atmospheric sources and sinks of carbon dioxide (CO2) and methane (CH4) in the pan-Arctic domain are extremely scarce, limiting our knowledge of carbon turnover in this climatically sensitive environment and the fate of the enormous ...

Hilbert Schemes, Separated Variables, and D-Branes [PDF]
, 1999 We explain Sklyanin's separation of variables in geometrical terms and construct it for Hitchin and Mukai integrable systems. We construct Hilbert schemes of points on $T^{*}\Sigma$ for $\Sigma = {\IC}, {\IC}^{*}$ or elliptic curve, and on ${\bf C}^{2}/{\

Ways of Intensification of Grass Seed Production [PDF]
Журнал інженерних наук, 2023 The main reason that restrains the development of seed production of perennial grasses is losses during harvesting, which depend on the agrotechnical properties of plants and the imperfection of existing means.

Effectiveness evaluation of energy crops production as a biofuel sources
Науковий вісник Львівського національного університету ветеринарної медицини та біотехнологій імені С.З. Гжицького. Серія: Сільськогосподарські науки, 2019 Energy crops are grown for energy purposes. Traditionally energy crops are corn and sugarcane which are grown for industrial scale ethanol, rapeseed for producing biodiesel, annual and perennial grasses, for example cane, miscanthus, cereal straw, as ...

A nanofabricated, monolithic, path-separated electron interferometer [PDF]
, 2016 We report a self-aligned, monolithic electron interferometer, consisting of two 45 nm thick silicon layers separated by 20 $\mu$m. This interferometer was fabricated from a single crystal silicon cantilever on a transmission electron microscope grid by ...
