Anomalies and D-branes in the Dabholkar-Park background

open access: yesJournal of High Energy Physics
We consider D-branes in the Dabholkar-Park (DP) background, a 9d orientifold theory obtained by gauging symmetry in the type IIB string theory compactified on a circle.

Charged chiral fermions from M5-branes

open access: yesJournal 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

open access: yesJournal 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 ...

Efficient Removal of Cd(II) and PB(II) Ions Using Innovatively Functionalized Poly(2,5‐Dihydro‐2,5‐Dimethoxyfuran) for Water Treatment Applications

open access: yesJournal of Applied Polymer Science, EarlyView.
Synthesis and surface functionalization of pDHMF for enhanced Cd(II) and Pb(II) adsorption from water. ABSTRACT In this work, a novel polymeric adsorbent was synthesized via the cationic polymerization of cis, trans‐2,5‐dihydro‐2,5‐dimethoxyfuran (DHMF), a renewable monomer derived from biomass. To improve its adsorption performance, synthesized poly(2,

Currents, charges and algebras in exceptional generalised geometry

open access: yesJournal of High Energy Physics, 2021
A classical E d(d)-invariant Hamiltonian formulation of world-volume theories of half-BPS p-branes in type IIb and eleven-dimensional supergravity is proposed, extending known results to d ≤ 6. It consists of a Hamiltonian, characterised by a generalised

Geometrical interpretation of D-branes in gauged WZW models [PDF]

open access: yes, 2001
We show that one can construct D-branes in parafermionic and WZW theories (and their orbifolds) which have very natural geometrical interpretations, and yet are not automatically included in the standard Cardy construction of D-branes in rational ...

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

open access: yesAnimal 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

Dual Functions of Dietary Rubber Seed Oil Supplementation: Enriching N‐3 Polyunsaturated Fatty Acids and Enhancing Antioxidant Capacity in Pekin Ducks

open access: yesAnimal Research and One Health, EarlyView.
Dietary RSO supplementation improved growth performance, simultaneously enriched n‐3 polyunsaturated fatty acids (n‐3 PUFA), and enhanced antioxidant capacity in Pekin ducks, which suggested that RSO has the potential to be a novel n‐3 PUFA source and an antioxidant for Pekin ducks to generate animal functional foods.

Cosmic branes and asymptotic structure

open access: yesJournal of High Energy Physics, 2019
Superrotations of asymptotically flat spacetimes in four dimensions can be interpreted in terms of including cosmic strings within the phase space of allowed solutions.
