Liouville Gravity from Einstein Gravity [PDF]

open access: yes, 2009
We show that Liouville gravity arises as the limit of pure Einstein gravity in 2+epsilon dimensions as epsilon goes to zero, provided Newton's constant scales with epsilon. Our procedure - spherical reduction, dualization, limit, dualizing back - passes several consistency tests: geometric properties, interactions with matter and the Bekenstein-Hawking

Methods for Calculating Empires in Quasicrystals

open access: yesCrystals, 2017
This paper reviews the empire problem for quasiperiodic tilings and the existing methods for generating the empires of the vertex configurations in quasicrystals, while introducing a new and more efficient method based on the cut-and-project technique ...

SL(2,C) Scheme Processing of Singularities in Quantum Computing and Genetics

open access: yesAxioms, 2023
Revealing the time structure of physical or biological objects is usually performed thanks to the tools of signal processing such as the fast Fourier transform, Ramanujan sum signal processing, and many other techniques.

Quasicrystal Tilings in Three Dimensions and Their Empires

open access: yesCrystals, 2018
The projection method for constructing quasiperiodic tilings from a higher dimensional lattice provides a useful context for computing a quasicrystal’s vertex configurations, frequencies, and empires (forced tiles).

Flavour-kinematics duality for Goldstone modes

open access: yesJournal of High Energy Physics, 2022
Three scalar effective field theories have special properties in terms of non-linear symmetries, soft limits and on-shell constructability that arise from their Goldstone nature: the non-linear σ-model, multi-DBI theory and the special Galileon.

(2+1) gravity for higher genus in the polygon model

open access: yes, 2004
We construct explicitly a (12g − 12)-dimensional space P of unconstrained and independent initial data for ’t Hooft’s polygon model of (2+1) gravity for vacuum spacetimes with compact genus-g spacelike slices, for any g ≥ 2.

Effective action for non-geometric fluxes duality covariant actions

open access: yesJournal of High Energy Physics, 2017
The (heterotic) double field theories and the exceptional field theories are manifestly duality covariant formulations, describing low-energy limit of various super-string and M-theory compactifications.

Promiscuous stimulation of HSP70 ATPase activity by parasite‐derived J‐domains

open access: yesFEBS Open Bio, EarlyView.
The malaria parasite Plasmodium falciparum exports three highly homologous yet functionally divergent J‐domain proteins into human erythrocytes. Here, we show that J‐domains isolated from all three proteins effectively stimulate the ATPase activity of both endogenous host and exported parasite HSP70 chaperones.

Gravity and lymphodynamics

open access: yesPhysiological Reports, 2022
AbstractThe lymphatic system is compromised in different groups of patients. To recognize pathology, we must know what is healthy. We use Near‐Infrared Fluorescence (NIRF) to assess peripheral lymphatic function in humans. We have shown that external factors such as exercise, hyperthermia, and pharmacological mediators influence the function of ...
