Charged chiral fermions from M5-branes

Journal of High Energy Physics, 2018
We study M5-branes wrapped on a multi-centred Taub-NUT space. Reducing to String Theory on the S 1 fibration leads to D4-branes intersecting with D6-branes.

D 3 ¯ $$ \overline{\textrm{D}3} $$ -branes and gaugino condensation

Journal of High Energy Physics, 2023
Anti-D3 branes at the bottom of warped throats, commonly used to uplift the cosmological constant in String-Theory de Sitter proposals, source a plethora of supersymmetry-breaking fluxes, that can interact nontrivially with other ingredients of the flux ...

GRAVITY ON NONCOMMUTATIVE D-BRANES [PDF]

International Journal of Modern Physics A, 2003
The effective action for the low energy scattering of two gravitons with a D-brane in the presence of a constant antisymmetric B field in bosonic string theory is calculated and the modification to the standard D-brane action to first order in α′ is obtained.

The Landau-Ginzburg to Calabi-Yau Dictionary for D-Branes [PDF]

, 2006
Based on work by Orlov, we give a precise recipe for mapping between B-type D-branes in a Landau-Ginzburg orbifold model (or Gepner model) and the corresponding large-radius Calabi-Yau manifold.

Exploring the Application of Waxes and Their Mixtures Oleogels in Ice Cream

Journal of the American Oil Chemists' Society, EarlyView.
ABSTRACT The objective of this work was to produce ice cream using waxes oleogels, aiming to improve its nutritional value while maintaining its physical‐chemistry characteristics. Five ice cream formulations were manufactured using (1) milk fat, (2) canola oil, and (3–5) canola oil‐oleogels. The oleogels were produced with beeswax (BEW), carnauba wax (

D-branes in topological membranes [PDF]

Nuclear Physics B, 2004
It is shown how two-dimensional states corresponding to D-branes arise in orbifolds of topologically massive gauge and gravity theories. Brane vertex operators naturally appear in induced worldsheet actions when the three-dimensional gauge theory is minimally coupled to external charged matter and the orbifold relations are carefully taken into account.

Matrix factorisations and D-branes on K3

, 2006
D-branes on K3 are analysed from three different points of view. For deformations of hypersurfaces in weighted projected space we use geometrical methods as well as matrix factorisation techniques.

One-loop vacuum amplitude for D-branes in constant electromagnetic field [PDF]

, 1996
Following Polchinski's approach we calculate the one-loop vacuum amplitude for two parallel D-branes connected by open bosonic (neutral or charged)string in a constant uniform electromagnetic (EM) field. For neutral string, external EM field contribution

Effects of Replacing Alfalfa Hay With Barley Silage in High‐Concentrate Diets: Chewing Behavior, Ruminal Fermentation, Total‐Tract Digestibility, and Milk Production of Dairy Cows in Mid‐Lactation Phase

Animal Research and One Health, EarlyView.
We assessed lactation productivity in dairy cows when replacing alfalfa hay with barley silage. A 50% replacement increased feed intake, whereas total replacement improved nutrient conversion to milk. Barley silage can effectively replace alfalfa hay, enhancing sustainability and resilience in dairy production amid forage quality constraints and market
