The Problem of the Observer in Physics

open access: yes, 2010
This paper has been withdrawn by the author. In this short paper I present a new approach to the problem of measurement, based on the difference between language (reality) and meta-language (meta-reality). This way, it will be shown as the measurement is a meta-sentence on a real event.

Metastatic niche shaped by host factors influences disseminated cancer cell fate

open access: yesFEBS Letters, EarlyView.
Metastasis is shaped not only by cancer cells but also by the environments they encounter. This review explores how factors such as aging, diet, the microbiome, lifestyle, and environmental exposures remodel organ‐specific niches in the lung, liver, bone, and brain, influencing where metastatic cells survive, remain dormant, or grow, and ultimately ...

A Physical-State Feedforward Observer with Disturbance-Adaptive Constraint Control for Active Suspension Electro-Hydraulic Actuators

open access: yesActuators
The high-performance control of active suspension electro-hydraulic actuators (ASEHA) is limited by a timing mismatch: the primary internal physical state (load pressure) responds to disturbances almost instantaneously, whereas the tracking error used ...

Invisible but not inaccessible—Revealing transient oligomers formed by intrinsically disordered proteins with solution NMR and complementary methods

open access: yesFEBS Letters, EarlyView.
Transient oligomers formed by intrinsically disordered proteins may be ‘invisible’ to direct detection yet remain accessible to solution NMR through equilibrium‐exchange measurements and pressure‐jump experiments. Complementary methods report on mass, stoichiometry, selected distance distributions, morphology, and internal packing.

Membrane composition and thermodynamic identity as boundaries of life for synthetic cell research

open access: yesFEBS Letters, EarlyView.
What makes a cell a cell? The boundary of a living cell is not just a wall. Read as a Markov blanket, the membrane separates internal from external states, generating identity and non‐equilibrium order. Can this identity be rebuilt from scratch in a synthetic cell?

The diffuse gamma-ray sky of a Milky Way analog: Local diversity and global constraints

open access: yesAstronomy & Astrophysics
Diffuse gamma-ray emission is a key tracer of cosmic rays (CRs) in galaxies, encoding information about their transport, energetics, and interaction with the interstellar medium.

Metastasis on pause: How dormant tumor cells stay hidden within the tumor microenvironment and evade immune surveillance

open access: yesMolecular Oncology, EarlyView.
Dormant cancer cells can hide in distant organs for years, evading treatment and the immune system. This review highlights how signals from the surrounding tissue and immune environment keep these cells inactive or trigger their reawakening. Understanding these mechanisms may help develop therapies to eliminate or control dormant cells and prevent ...

Super-Twisting Sliding Mode Observer With Physics Informed Neural Network Compensation for Ultra-Low-Speed Sensor Less PMSM Drives for Electric Vehicle Applications

open access: yesIEEE Access
Ultra-low-speed sensor less control of Permanent Magnet Synchronous Motor (PMSM) drives remains a challenging problem because of weak back-EMF signals, parameter uncertainties, inverter nonlinearities, and external disturbances. Conventional Sliding Mode

Finding novel vulnerabilities of hypomorphic BRCA1 alleles

open access: yesMolecular Oncology, EarlyView.
Synthetic lethality screens performed to identify novel vulnerabilities often model complete gene loss, thereby overlooking patient‐derived hypomorphic mutations. In this study, we have performed genome‐wide CRISPR screens on BRCA1 hypomorphic mutations, showing BRCA1I26A behaves like wild‐type, while BRCA1R1699Q mimics deficiency. Furthermore, we have
