Visible‐Light Photocatalyzed Selective Synthesis of 1,2‐ or 1,3‐Dithianes From Thietanes: An Experimental and Theoretical Study

Advanced Synthesis &Catalysis, EarlyView.
Although this article formally presents a regioselective photochemical ring enlargement of thietanes into 1,2‐ or 1,3‐dithianes, time‐dependent density functional theory calculations have revealed that 1,3‐dithianes are in fact formed thought photoinduced hydrogen atom transfers from 1,2‐dithianes initially resulting from the ring enlargement using ...

The global B − L symmetry in the flavor-unified SU(N) theories

Journal of High Energy Physics
We study the origin of the global B − L symmetry in a class of flavor-unified theories with gauge groups of SU(N ≥ 6). In particular, we focus on the SU(8) theory which can minimally embed three-generational SM fermions non-trivially.

Predicting the flavour and SUSY flavour structure from grand unified theories

, 2016
Grand Unified Theories (GUTs) offer an attractive framework for flavour models, since they feature relations between quarks and leptons. Combining them with Supersymmetry (SUSY) and flavour symmetries, we derive predictions for the flavour and SUSY flavour structure from various GUT models and discuss how the double missing partner mechanism (DMPM ...

Can gauge theories of flavour be accessible at the LHC? [PDF]

Proceedings of The European Physical Society Conference on High Energy Physics — PoS(EPS-HEP2017), 2018
Horizontal gauge symmetries between fermion families and their spontaneous breaking can be at the origin of the inter-family mass hierarchies. The corresponding gauge bosons must have flavor changing couplings to fermions and generically the very stringent limits on their masses arise from flavour changing phenomena and CP-violation.

DKK3 Initially Preserves Acinar Integrity Through MEK‐Fos Signaling, but Later Switches to an Oncogenic Role in Pancreatic Cancer

Advanced Science, EarlyView.
In pancreatic cancer, the protein DKK3 is found to play a complex role: it initially slows early tumor growth but later promotes tumor aggressiveness. DKK3 expression evolves during progression and drives cancer severity by orchestrating cellular and molecular signaling pathways.

The gauge coupling evolutions of an SU(8) theory with the maximally symmetry breaking pattern

Journal of High Energy Physics
We study the renormalizable group equations (RGEs) of the extended strong and weak gauge couplings in an SU(8) theory, where three-generational SM fermions are non-trivially embedded.
