, 2017 We discuss new-type grand unified theories based on grand unified groups broken to their special subgroups as well as their regular subgroups. In the framework, when we construct four-dimensional (4D) chiral gauge theories, i.e., the Standard Model (SM),

Molecular bases of circadian magnesium rhythms across eukaryotes
FEBS Letters, EarlyView.Circadian rhythms in intracellular [Mg2+] exist across eukaryotic kingdoms. Central roles for Mg2+ in metabolism suggest that Mg2+ rhythms could regulate daily cellular energy and metabolism. In this Perspective paper, we propose that ancestral prokaryotic transport proteins could be responsible for mediating Mg2+ rhythms and posit a feedback model ...

Nuclear Physics B, 2021 We consider a non-supersymmetric E6 Grand Unified Theory (GUT) with intermediate trinification symmetry SU(3)C×SU(3)L×SU(3)R×D (D denoted as D-parity for discrete left-right symmetry) and study the effect of one-loop threshold corrections arising due to ...

FEBS Letters, EarlyView.This perspective highlights emerging insights into how the circadian transcription factor CLOCK:BMAL1 regulates chromatin architecture, cooperates with other transcription factors, and coordinates enhancer dynamics. We propose an updated framework for how circadian transcription factors operate within dynamic and multifactorial chromatin landscapes ...

Top-Down Approach to Unified Supergravity Models
, 1994 We introduce a new approach for studying unified supergravity models. In this approach all the parameters of the grand unified theory (GUT) are fixed by imposing the corresponding number of low energy observables.

, 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.

Disordered but rhythmic—the role of intrinsic protein disorder in eukaryotic circadian timing
FEBS Letters, EarlyView.Unstructured domains known as intrinsically disordered regions (IDRs) are present in nearly every part of the eukaryotic core circadian oscillator. IDRs enable many diverse inter‐ and intramolecular interactions that support clock function. IDR conformations are highly tunable by post‐translational modifications and environmental conditions, which ...

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 ...

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

An Exceptional SSM from E6 Orbifold GUTs with intermediate LR symmetry
, 2010 We propose a class of E6-based local orbifold Grand Unified Theories (GUTs) which yield an exceptional supersymmetric standard model as their low energy theory including leptoquark and unhiggs exotics and a Z' at the TeV scale. Unification is achieved in
