Nonperturbative bounds on scattering of massive scalar particles in d ≥ 2
Journal of High Energy Physics, 2022 We study two-to-two scattering amplitudes of a scalar particle of mass m. For simplicity, we assume the presence of ℤ2 symmetry and that the particle is ℤ2 odd.

Exotic tensor gauge theory and duality [PDF]
, 2002 Gauge fields in exotic representations of the Lorentz group in D dimensions - i.e. ones which are tensors of mixed symmetry corresponding to Young tableaux with arbitrary numbers of rows and columns - naturally arise through massive string modes and in ...

Towards metric-like higher spin gauge theories in three dimensions [PDF]
, 2012 We consider the coupling of a symmetric spin-3 gauge field φμνρ to three-dimensional gravity in a second-order metric-like formulation. The action that corresponds to an SL(3,R)×SL(3,R)?> Chern–Simons theory in the frame-like formulation is identified to

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 ...

E 8 instantons on type-A ALE spaces and supersymmetric field theories
Journal of High Energy Physics, 2017 We consider the 6d superconformal field theory realized on M5-branes probing the E 8 end-of-the-world brane on the deformed and resolved ℂ 2/ℤ k singularity.

On the Trace Anomaly as a Measure of Degrees of Freedom [PDF]
, 2000 Recent conjectures of the c-theorem in four and higher dimensions have suggested that the coefficient of the Euler characteristic in the trace anomaly could measure the degrees of freedom in field theory and decrease along the renormalization-group flow.

Topological couplings in higher derivative extensions of supersymmetric three-form gauge theories [PDF]
Journal of High Energy Physics, 2018 A bstractWe consider a topological coupling between a pseudo-scalar field and a 3- form gauge field in N=1$$ \mathcal{N}=1 $$ supersymmetric higher derivative 3-form gauge theories in four spacetime dimensions.

Emerging role of ARHGAP29 in melanoma cell phenotype switching
Molecular Oncology, EarlyView.This study gives first insights into the role of ARHGAP29 in malignant melanoma. ARHGAP29 was revealed to be connected to tumor cell plasticity, promoting a mesenchymal‐like, invasive phenotype and driving tumor progression. Further, it modulates cell spreading by influencing RhoA/ROCK signaling and affects SMAD2 activity. Rho GTPase‐activating protein

Topological dualities in the Ising model
, 2021 We relate two classical dualities in low-dimensional quantum field theory: Kramers-Wannier duality of the Ising and related lattice models in $2$ dimensions, with electromagnetic duality for finite gauge theories in $3$ dimensions.
