Copper–Collagen Interactions Regulate the Mechanical and Invasive Properties of Tumor Spheroids
Ionic copper is investigated as a modulator of tumor spheroid growth and invasiveness in a 3D microfluidic glioblastoma model. Copper exposure alters metabolic activity, cytoskeletal organization, protrusion dynamics, and EMT‐related phenotypes in a dose‐ and timing‐dependent manner, revealing how copper bioavailability shapes tumor aggressiveness ...

Respiratory Organ‐on‐a‐Chip for Disease Modeling: From Architecture to Functional Integration
Respiratory organ‐on‐a‐chip (ROC) models capture key mechanical and cellular cues of the human respiratory system, enabling quantitative dissection of disease mechanisms. This review links ROC architectures to disease modeling, functional integration, and commercialization, and proposes a decision framework that aligns model complexity with mechanistic

Isolated photon cross section and resummation of the logarithms of the cone radius
The cone isolation criterion used in large-pt photon experiments generates logarithms of the cone radius in the theoretical cross sections. When a small radius is used, unitarity is violated as the inclusive cross section is smaller than the isolated one.

This study relies on the development of a new sensor that can detect two closely related proteins involved in Alzheimer's disease at the same time. Unlike traditional methods, it works in natural conditions and does not require sample pretreatment. The device is highly sensitive and was successfully tested on patient samples, offering promises for ...

Towards numerical two-loop integrand reduction
We present a method for the integrand-level reduction of two-loop helicity amplitudes in both d = 4 – 2ϵ and d = 4 dimensions. The amplitude is expressed in terms of a set of Feynman integrals and their coefficients that depend on the external kinematics.

Strain Engineering of Magnetoresistance and Magnetic Anisotropy in CrSBr
Biaxial compressive strain significantly enhances magnetoresistance and critical saturation fields in thin flakes of the 2D magnet CrSBr, along all three crystallographic axes. First‐principles calculations link these effects to strain‐induced increases in exchange interactions and magnetic anisotropy.

Order-v 2 relativistic corrections to heavy-quark fragmentation into P-wave quarkonium states
Within the framework of nonrelativistic QCD (NRQCD) factorization, and based on the Collins-Soper operator definition of fragmentation functions, we present a systematic calculation of the fragmentation functions for a heavy quark fragmenting into color ...

Transient Charging of Mixed Ionic‐Electronic Conductors by Anomalous Diffusion
This article explores charge transport in mixed ionic‐electronic conductors (MIECs) through electrochemical impedance spectroscopy and transient current analysis. Focusing on PEDOT:PSS, WO3, and n‐doped PBDF, it uncovers the impact of anomalous diffusion via fractional modeling. The study reveals key correlations that deepen understanding and guide the

New high order relations between physical observables in perturbative QCD
We exploit the fact that within massless perturbative QCD the same Green's function determines the hadronic contribution to the ø decay width and the moments of the e + e \Gamma cross section.

Kelvin Probe Force Microscopy in Bionanotechnology: Current Advances and Future Perspectives
Kelvin probe force microscopy (KPFM) enables the nanoscale mapping of electrostatic surface potentials. While widely applied in materials science, its use in biological systems remains emerging. This review presents recent advances in KPFM applied to biological samples and provides a critical perspective on current limitations and future directions for
