Physics of Selective Targeting of Cancer Cells by Magnetoelectric Nanoparticles: Exploring the Role of Conductivity and Capacitance in Tumor‐Specific Attraction

open access: yesAdvanced Theory and Simulations, EarlyView.
Magnetoelectric nanoparticles exploit cancer cells' electrical vulnerabilities—altered membrane charge and higher capacitance—to achieve tumor‐specific targeting without bioreagents. MATLAB simulations reveal how electromagnetic forces create targeting specificity, while external magnetic fields enhance precision. This may enable wirelessly controlled,

Optically Switchable Fluorescence Enhancement at Critical Interparticle Distances

open access: yesAdvanced Theory and Simulations, EarlyView.
In this work, we present the results of a complete FDTD (Finite Difference Time Domain) model specifically tailored for the precise determination of critical interparticle distances yielding observable fluorescence enhancement. We further report an optical switch applied on a metal nanoparticle to actively control the radiative decay rate of a closely ...

REMARKS ON MIURA-ORI, A JAPANESE FOLDING METHOD

open access: yesJournal of Industrial Design and Engineering Graphics, 2009
Miura-ori is a Japanese folding technique named after Prof. Koryo Miura, the University of Tokyo. It is used for solar panels because it can be unfolded into its rectangular shape by pulling on one corner only.

Discrete mathematics, discrete physics and numerical methods

open access: yesLe Matematiche, 2007
Discrete mathematics has been neglected for a long time. It has been put in the shade by the striking success of continuous mathematics in the last two centuries, mainly because continuous models in physics proved very reliable, but also because of the greater difficulty in dealing with it.

Non‐Invasive Diagnosis of Chronic Myocardial Infarction via Composite In‐Silico‐Human Data Learning

open access: yesAdvanced Science, EarlyView.
This study presents a non‐invasive machine learning model to identify infarct regions in the left ventricle using cardiac strain data. By combining rodent‐based simulated data with limited human data, the model achieves high accuracy in predicting infarct size and location without the need for gadolinium contrast agents, offering a promising ...

Prediction of Microstructural Representativity From A Single Image

open access: yesAdvanced Science, EarlyView.
Accurately estimating the reliability of phase fraction measurements from limited microstructural data remains a key challenge and is rarely reported for this reason. ImageRep addresses the problem by adapting the Two‐Point Correlation function to assess representativity from a single image.

Split‐Aperture Xolography – Linear Volumetric Photoactivation with Short Axial Dimension and Low out of Focus Excitation

open access: yesAdvanced Science, EarlyView.
Stepwise excitation of dual‐color responsive molecules in a novel intersecting half‐cone geometry provides excellent spatial resolution while retaining the high efficiency and thus speed of the overall process. The approach provides volumetric methods with an enhanced performance at the nanoscale.

Interference Pattern Caused by Bilateral Bone Conduction Stimulation Impairs Sound Localization

open access: yesAdvanced Science, EarlyView.
This work explores how crosstalk‐induced wave interference affects bone conduction (BC) sound localization. Using a theoretical model, cadaveric vibrometry, and psychoacoustic tests, atypical BC lateralization patterns are revealed that contradict air conduction (AC) principles.
