Optically detected magnetic resonance of nitrogen-vacancy centers in microdiamonds inside nanopolycrystalline diamond anvil cell
We demonstrated optically detected magnetic resonance (ODMR) of nitrogen-vacancy (NV) centers in microdiamonds inside a diamond anvil cell pressurized with nanopolycrystalline diamond (NPD) anvils. NPD exhibits high optical transparency, superior hardness, and low thermal conductivity, making it suitable for optical and spectroscopic measurements under high-pressure and high-temperature conditions. We observed the ODMR signal from an ensemble of NV centers under high pressures, reaching up to 2…

Attosecond-resolved probing of recolliding electron wave packets in liquids and aqueous solutions
High-harmonic spectroscopy (HHS) in liquids promises real-time access to ultrafast electronic dynamics in the native environment of chemical and biological processes. While electron recollision has been established as the dominant mechanism of high-harmonic generation (HHG) in liquids, resolving the underlying electron dynamics has remained elusive. Here we demonstrate attosecond-resolved measurements of recolliding electron wave packets, extending HHS from neat liquids to aqueous solutions. Us…

Yo lo de que RTVE retransmita San Fermín... Pues lo veo del siglo XIX la verdad. Hablan de respeto al animal, de adorarlo y todas esas falacias, porque el respeto torturando hasta la muerte al toro por puro placer, empleando descargas eléctricas y varas para moverlos, hacerlos correr y dejarlos sin comer unos días para que corran mšs... No se, igual es que el respeto significa una cosa u otra según seas taurino o no.

Using Psychophysiological Insights to Evaluate the Impact of Loot Boxes on Arousal
This study investigates the psychophysiological effects of loot box interactions in video games and their potential similarities to those recorded during gambling interactions. Using electrodermal activity (EDA) measurements, the research examines player arousal during loot box interactions and explores the relationship between Internet Gaming Disorder (IGD) severity and loot box interactions from a psychophysiological perspective. The study employs a custom-designed game to control experimenta…

Quantitative imaging of 478-keV prompt gamma rays from boron neutron capture reactions
The accurate imaging and quantitative measurement of 478-keV prompt gamma rays are critical for advancing boron neutron capture therapy (BNCT), a promising cancer treatment. Although numerical simulations have indicated that such measurements are feasible, their practical application has proven challenging. This study introduces a gamma-ray imaging detector designed specifically for precise BNCT measurements. Using boron-rich phantom samples, we successfully imaged 478-keV gamma rays and establ…

Full-field rheo-optical analysis of wormlike and networked micellar structures under uniaxial extensional flow
The present study proposes a novel full-field extensional rheo-optical technique to investigate the relationship between the rheological properties and internal structural deformation of complex fluids under uniaxial extensional flow. Macroscopic viscoelasticity from rheological measurements and microscopic birefringence from optical measurements are integrated to evaluate the microstructural deformation and orientation of the fluids under extensional stress. The proposed technique integrates a…

Magneto-cubic and magneto-linear dependence observed in an in-plane anomalous Hall magnet
The Hall effect, particularly that arising from in-plane magnetic field, has recently emerged as a sensitive probe of quantum geometric properties in solids. Especially in trigonal systems, in-plane anomalous Hall effect (AHE) can be explicitly induced by nontrivial off-diagonal coupling between the magnetic field and the Hall vector on the principal plane. Here we elucidate multipolar dependence of the off-diagonal coupling in the in-plane AHE, by systematically measuring on the (001) principa…

Long-Term Variability in Physiological-Arousal Relationships for Robust Emotion Estimation
Estimating emotional states from physiological signals is a central topic in affective computing and psychophysiology. While many emotion estimation systems implicitly assume a stable relationship between physiological features and subjective affect, this assumption has rarely been tested over long timeframes. This study investigates whether such relationships remain consistent across several months within individuals. We developed a custom measurement system and constructed a longitudinal data…
