Scale invariance in the spectral action
, 2006 The arbitrary mass scale in the spectral action for the Dirac operator is made dynamical by introducing a dilaton field. We evaluate all the low-energy terms in the spectral action and determine the dilaton couplings.

Single‐molecule DNA flow‐stretch assays for high‐throughput DNA–protein interaction studies
FEBS Open Bio, EarlyView.We describe an optimised single‐molecule DNA flow‐stretch assay that visualises DNA–protein interactions in real time. Linear DNA fragments are tethered to a surface and stretched by buffer flow for fluorescence imaging. Using λ and φX174 DNA, this protocol enhances reproducibility and accessibility, providing a versatile approach for studying diverse ...

Only-phase Popov action: thermodynamic derivation and superconducting electrodynamics
We provide a thermodynamic derivation of the only-phase Popov action functional, which is often adopted to study the low-energy effective hydrodynamics of a generic nonrelativistic superfluid.

Physical determination of the action
, 2015 Mein Ziel ist eine Begründung der Physik aus der Operationalisierung ihrer Grundmaße. Wir beginnen mit der klassischen und relativistischen Kinematik. Dann greifen wir einen programmatischen Entwurf von Heinrich Hertz auf und gelangen über die Quantifizierung von Energie und Impuls zu den Bewegungsgleichungen und dem Wirkungsfunktional.

FEBS Open Bio, EarlyView.This protocol paper outlines methods to establish the success of a time‐resolved serial crystallographic experiment, by means of statistical analysis of timepoint data in reciprocal space and models in real space. We show how to amplify the signal from excited states to visualise structural changes in successful experiments.

ACTION RESEARCH AS A TOOL OF DIDACTICS OF PHYSICS
, 2019 Este es un análisis del significado de la investigación acción como estrategia para el desarrollo de la didáctica de la física. Mostramos los pros y los contras a la hora de implementarla en el diseño de la didáctica de la Física, entendida esta última ...

FEBS Open Bio, EarlyView.Matrix metalloproteinase‐9 (MMP9) drives ovarian cancer progression. Using MMP9‐null cells (M9‐KO) created from ovarian cancer cells, we found MMP9 loss did not block Epidermal Growth Factor (EGF)‐driven E‐cadherin dissolution or EMT but delayed and reduced EGF‐driven membrane protrusions. Transient MMP9 re‐expression drove membrane protrusion.

COST P21 "The physics of droplets"
, 2006 During the last five years, microfluidic technology has emerged. The applications are very fruitful in many domains: biotechnology, food science, reprographics, microelectronics and nanoscience, cleaning, cooling, tribology etc.

FEBS Open Bio, EarlyView.14‐day casting‐induced immobilization reduced gastrocnemius muscle mass and increased non‐heme iron and ferritin heavy chain levels. Despite iron accumulation, transferrin receptor 1 and iron regulatory protein 2 were paradoxically upregulated. Lipid peroxidation was elevated without compensatory antioxidant responses.

Framing Human Action in Physics: Valid Reconstruction, Invalid Reduction
, 2022 We propose framing human action in physics before reaching to biology and social sciences, rearranging the order of their usual deployment. As an example, consider efforts to model altruism that start in a frame of psychological or social attributes such
