Some recent results for SU(3)$$ SU(3) $$ and octonions within the geometric algebra approach to the fundamental forces of nature
Anthony Lasenby
Jan 09, 2023
Different ways of representing the group S U ( 3 ) $$ SU(3) $$ within a Geometric Algebra approach are explored. As part of this, we consider characteristic multivectors for S U ( 3 ) $$ SU(3) $$ and how these are linked with...
SU(2)^2xU(1)-invariant G_2-instantons on the AC limit of the C7 family
We construct SU(2)^2xU(1)-invariant G_2-instantons on the asymptotically conical limit of the C7 family of G_2-metrics. The construction uses a dynamical systems approach involving perturbations of an abelian solution and a...

Phenomenology of a SU(2) triplet Higgs.
Vera Agustin Sabio
Feb 15, 2010
We study the Renormalization Group (RG) evolution of the couplings in
a model with a real SU(2) triplet in the Higgs sector. Insisting that the
model remain valid up to 1 TeV we show that it is possible for there to
be no light...

Investigating X chromosome non-disjunction in <em>Drosophila melanogaster su(var)3-9</em> mutants
Meiotic recombination is a highly regulated process necessary for promoting proper chromosome disjunction during the first meiotic division. Notably, reduced levels of meiotic recombination are observed in heterochromatic...

Exact properties of an integrated correlator in N = 4 SU( N ) SYM
Abstract: We present a novel expression for an integrated correlation function of four superconformal primaries in SU(N) N = 4 supersymmetric Yang-Mills (N = 4 SYM) theory. This integrated correlator, which is based on...
Single-photon-multi-layer-interference lithography for high-aspect-ratio and three-dimensional SU-8 micro-/nanostructures.
We report microstructures of SU-8 photo-sensitive polymer with high-aspect-ratio, which is defined as the ratio of height to in-plane feature size. The highest aspect ratio achieved in this work exceeds 250. A multi-layer and...
Non-Lorentzian SU(1, n) Spacetime Symmetry In Various Dimensions
We discuss non-Lorentzian Lagrangian field theories in $2n-1$ dimensions that
admit an $SU(1,n)$ spacetime symmetry which includes a scaling transformation.
These can be obtained by a conformal compactification of a...
Evidence for a non-supersymmetric 5d CFT from deformations of 5d SU(2) SYM
We study supersymmetry breaking deformations of the $\mathcal{N}=1$ 5d fixed
point known as $E_1$, the UV completion of $SU(2)$ super-Yang-Mills. The phases
of the non-supersymmetric theory can be characterized by Chern-Simons...

Abstract: We study supersymmetry breaking deformations of the N = 1 5d fixed point known as E1, the UV completion of SU(2) super-Yang-Mills. The phases of the non- supersymmetric theory can be characterized by Chern-Simons terms...

Neuroscience out of control
A major challenge in systems neuroscience is to understand how the dynamics of neural circuits give rise to behaviour. Analysis of complex dynamical systems is also at the heart of control engineering, where it is central to the...
Lesions of abdominal connectives reveal a conserved organization of the calling song central pattern generator (CPG) network in different cricket species
Abstract: Although crickets move their front wings for sound production, the abdominal ganglia house the network of the singing central pattern generator. We compared the effects of specific lesions to the connectives of the...
Genomic mapping of Suppressor of Hairy-wing binding sites in Drosophila.

Mar 27, 2020
BACKGROUND: Insulator elements are proposed to play a key role in the organization of the regulatory architecture of the genome. In Drosophila, one of the best studied is the gypsy retrotransposon insulator, which is bound by...
Optimal anticipatory control as a theory of motor preparation
Across a range of motor and cognitive tasks, cortical activity can be accurately described by low-dimensional dynamics unfolding from specific initial conditions on every trial. These "preparatory states" largely determine the...
Anomaly interplay in U(2) gauge theories
We discuss anomaly cancellation in $U(2)$ gauge theories in four dimensions.
For a $U(2)$ gauge theory defined with a spin structure, the vanishing of the
bordism group $\Omega_5^{\text{Spin}}(BU(2))$ implies that there can be...
Family focused interventions that address parental domestic violence and abuse, mental ill-health, and substance misuse in combination

Sep 02, 2022
Parental domestic violence and abuse (DVA), mental ill-health (MH), and substance misuse (SU) are three public health issues that tend to cluster within families, risking negative impacts for both parents and children. Despite...
Anomaly interplay in U(2) gauge theories
Abstract: We discuss anomaly cancellation in U(2) gauge theories in four dimensions. For a U(2) gauge theory defined with a spin structure, the vanishing of the bordism group Ω5Spin (BU(2)) implies that there can be no global...
Mesenchymal stem cells and management of COVID-19 pneumonia.
Su M Metcalfe

Human coronavirus, hCoV-19, is highly pathogenic with severe pneumonia associated with rapid virus replication. Arising in Wuhan China December 2019, the current COVID-19 epidemic has rapidly grown with person-to-person...
Global anomalies in the Standard Model(s) and beyond
Abstract: We analyse global anomalies and related constraints in the Standard Model (SM) and various Beyond the Standard Model (BSM) theories. We begin by considering four distinct, but equally valid, versions of the SM, in...
Five-Dimensional Path Integrals for Six-Dimensional Conformal Field
Theories
In this paper we derive Ward-Takahashi identities from the path integral of
supersymmetric five-dimensional field theories with an $SU(1,3)$ spacetime
symmetry in the presence of instantons. We explicitly show how $SU(1,3)$...
