An epithelial GPR35 isoform supports tumor‐associated transcriptional and metabolic phenotypes
FEBS Letters, EarlyView.GPR35 generates two functionally distinct isoforms with previously unresolved roles. GPR35‐short mediates immune‐cell chemotaxis, while GPR35‐long is enriched in colorectal cancer epithelium, where it supports increased metabolism, proliferation, and tumor‐associated transcriptional programs.

Massless S-matrix bootstraps and RG flows
Journal of High Energy PhysicsWe find complete solutions of S-matrix bootstrap equations for the scatterings of massless particles in (1+1) dimensions with A n symmetries. We show that only three types (minimal, diagonal, and saturated cases) of these S-matrices can generate RG flows

Peripheral lysosomes recruit PLEKHG3 to focal adhesions and restrain protrusion dynamics
FEBS Letters, EarlyView.Proximity‐dependent labeling at the LAMTOR complex revealed the Rho GEF PLEKHG3 as a lysosome‐proximal protein directing the study toward the influence of lysosome positioning on actin dynamics and cell motility. We show that PLEKHG3 colocalizes with lysosomes at focal adhesion sites and observe that forced peripheral dispersion of lysosomes hinders ...

AdS S-matrix for massive vector fields
Journal of High Energy PhysicsWe generalize a recent “AdS S-matrix” formulation for interacting massive scalars on AdS spacetimes to the case of massive vector fields. This method relies on taking the infinite radius limit for scattering processes perturbatively, which is analyzed ...

Epigenetic reprogramming of lineage switching in cancer
FEBS Letters, EarlyView.Cancer cells rarely commit to a single identity. Epigenetic mechanisms and tumor microenvironment cues push epithelial cells toward flexible, hybrid states that can shift into mesenchymal, neuroendocrine, or stem‐like fates, driving metastasis, drug resistance, and tumor heterogeneity. Targeting the epigenetic regulators behind these transitions, using

S-MATRIX FROM THE METAPLECTIC REPRESENTATION
Modern Physics Letters A, 1992 We show how the S-matrix for bosons in an external field can be derived directly from the infinite-dimensional metaplectic representation, in terms of the classical scattering operator.

The S-matrix bootstrap II: two dimensional amplitudes
Journal of High Energy Physics, 2017 We consider constraints on the S-matrix of any gapped, Lorentz invariant quantum field theory in 1 + 1 dimensions due to crossing symmetry and unitarity.

The microbiome in human skin aging
FEBS Letters, EarlyView.Age‐related skin changes encompass the well‐known visible phenotypic alterations, together with microbiome dysbiosis and a series of molecular aging hallmarks. These hallmarks characterize not only a fully stablished aged phenotype but also the skin aging process itself.

VIRTUAL BLACK HOLES AND THE S-MATRIX [PDF]
International Journal of Modern Physics D, 2004 A brief review on virtual black holes is presented, with special emphasis on phenomenologically relevant issues like their influence on scattering or on the specific heat of (real) black holes. Regarding theoretical topics, the results important for (the avoidance of) information loss are summarized.After recalling Hawking's Euclidean notion of virtual

On beautiful analytic structure of the S-matrix
New Journal of Physics, 2019 For an exponentially decaying potential, analytic structure of the s -wave S -matrix can be determined up to the slightest detail, including position of all its poles and their residues. Beautiful hidden structures can be revealed by its domain coloring.
