XUE: Molecular Inventory in the Inner Region of an Extremely Irradiated Protoplanetary Disk
(2023-12-01)We present the first results of the eXtreme UV Environments (XUE) James Webb Space Telescope (JWST) program, which focuses on the characterization of planet-forming disks in massive star-forming regions. These regions are ... -
The XXL Survey: : XXIX. GMRT 610 MHz continuum observations
(2018-12-01)We present the 25 square-degree GMRT-XXL-N 610 MHz radio continuum survey, conducted at 50 cm wavelength with the Giant Metrewave Radio Telescope (GMRT) towards the XXL Northern field (XXL-N). We combined previously published ... -
The X–shooter/ALMA Sample of Quasars in the Epoch of Reionization. II. Black Hole Masses, Eddington Ratios, and the Formation of the First Quasars
(2022-12-20)We present measurements of black hole masses and Eddington ratios (λ Edd) for a sample of 38 bright (M 1450 < −24.4 mag) quasars at 5.8 ≲ z ≲ 7.5, derived from Very Large Telescope/X-shooter near-IR spectroscopy of their ... -
Yangian Symmetry for the Tree Amplituhedron
(2017-06-29)Tree-level scattering amplitudes in planar N=4 super Yang-Mills are known to be Yangian-invariant. It has been shown that integrability allows to obtain a general, explicit method to find such invariants. The uplifting of ... -

The Yasso07 soil carbon model - Testing against repeated soil carbon inventory
(2012-12-15)Forest soils store large amounts of carbon (C), and releases of C from this pool may significantly increase the CO 2 concentration in the atmosphere. Organic matter decomposition in soils has been shown to strongly depend ... -

The yield gap in some beet producing countries
(2012)The efficiency of an arable crop production system can be expressed as the yield gap, defining the difference between the potential and the actual yield; the larger the gap the less efficient the system. One way to assess ... -
The yield gap in some sugar beet producing countries
(2012-07)The efficiency of an arable crop production system can be expressed as the yield gap, the difference between the potential yield and the actual yield. The larger the gap, the less efficient the system. One way to assess ... -
Yield loss of winter oilseed rape in relation to severity of stem canker (Leptosphaeria maculans ) in the UK
(1999)The relationships between yield loss and incidence or severity of stem canker in winter oilseed rape were analysed using data from experiments at Rothamsted in 1991/92, Withington in 1992/93, Boxworth in 1993/94 and ... -
