Tri-unification: a separate SU(5) for each fermion family
Journal of High Energy PhysicsIn this paper we discuss SU(5)3 with cyclic symmetry as a possible grand unified theory (GUT). The basic idea of such a tri-unification is that there is a separate SU(5) for each fermion family, with the light Higgs doublet(s) arising from the third ...

FEBS Letters, EarlyView.Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

A new flavour imprint of SU(5)-like grand unification and its LHC signatures
Physics Letters B, 2015 We point out that the hypothesis of an SU(5)-like supersymmetric Grand Unified Theory (GUT) implies a generic relation within the flavour structure of up-type squarks. Contrary to other well-known SU(5) relations between the down-quark and charged lepton

Gauge fields and quantum theory [PDF]
, 1996 This thesis investigates the problems within quantum mechanics for the Bohm model caused by Lorentz invariance and the existence of photons. A model describing the electromagnetic interactions of fermions is produced which does not use photons and avoids

From mice to humans—divergent strategies for intestinal homeostasis and regeneration
FEBS Letters, EarlyView.Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

Universally finite gravitational and gauge theories
Nuclear Physics B, 2015 It is well known that standard gauge theories are renormalizable in D=4 while Einstein gravity is renormalizable in D=2. This is where the research in the field of two derivatives theories is currently standing.

, 2015 If the past exists only in its retelling, I’ll tell you that I picture her with a Greek hook to her nose. She’s maybe a little astigmatic, fond of her library and matters of state. She’s more charming than most but no more murder-prone than her forbears or than having a brother-husband might make anyone.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment
Molecular Oncology, EarlyView.This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Unitarity constraints on large multiplets of arbitrary gauge groups
Nuclear Physics BWe impose partial-wave unitarity on 2→2 tree-level scattering processes to derive constraints on the dimensions of large scalar and fermionic multiplets of arbitrary gauge groups.

Naturally light Higgs doublet in supersymmetric E6 grand unified theory
, 1985 We show how some supersymmetric E6 grand unified theories, which may arise as the low-energy limit of superstring theory, provide a natural solution of the fine-tuning ...
