Heterotic Weight Lifting [PDF]

open access: yes, 2009
We describe a method for constructing genuinely asymmetric (2,0) heterotic strings out of N=2 minimal models in the fermionic sector, whereas the bosonic sector is only partly build out of N=2 minimal models.

Long‐Term Storage of Meteoric Water in the Variscan Basement: Stable Isotope Constraints (δD–δ18O)

open access: yesTerra Nova, Volume 38, Issue 2, Page 116-123, April 2026.
ABSTRACT F‐Ba‐Pb‐Zn (±Ag) deposits near the unconformity between the Armorican and Aquitaine basins formed by mixing surface waters and brines with fluid ascending from the basement. To better constrain the source of this fluid and the conditions of mixing, we analyzed the hydrogen (δDwater) and oxygen (δ18Owater) isotopic composition of water trapped ...

The embedding structure of unitary N=2 minimal models [PDF]

open access: yes, 1997
We derive the embedding structure of unitary N=2 minimal models and show as a result that these representations have a degeneration of uncharged singular states. This corrects some earlier mistakes made in the literature.

Pre‐Season Total Energy Expenditure and Dietary Intake of Professional Male Soccer Players: A Doubly Labelled Water Study

open access: yesEuropean Journal of Sport Science, Volume 26, Issue 3, March 2026.
ABSTRACT Limited data exist describing how professional footballers meet their energy requirements during pre‐season, a phase characterised by increased training volume and a progressive shift from general conditioning to football‐specific preparation.

Early‐Life Respiratory Emissions of CO₂, CH₄, and N₂O in Pre‐Weaned Dairy‐Bred Calves

open access: yesJournal of Sustainable Agriculture and Environment, Volume 5, Issue 1, March 2026.
ABSTRACT Greenhouse gas (GHG) emissions from livestock are a major contributor to climate change, with cattle known to be the principal contributor through enteric fermentation, manure management, and metabolic processes. This study investigates the emission rates of CO₂, CH₄, and N₂O in pre‐weaned calves aged 12 to 86 days, focusing on the ...

A Temporally Consistent Spatial Gradient in Methane Ebullition From a Eutrophic Lake

open access: yesJournal of Geophysical Research: Biogeosciences, Volume 131, Issue 3, March 2026.
Abstract Gas bubble emission (ebullition) from lake sediment is a prominent source of the greenhouse gas methane (CH4) to the atmosphere, but the stochastic nature of bubble release and thus high variability in space and time makes the estimation of lake CH4 ebullition challenging.
