Dynamics signature of polyamorphic transition and single-crystal crystallization in Ce-Al metallic glass under high pressure

Federico ZONTONE · Hongbo LOU · Yuxin LIU · Zhidan ZENG · y 1 más

We propose to study the atomic relaxation dynamics of the Ce-Al MGs during both compression and decompression from ambient pressure through the polyamorphic transition and eventually close-to-crystallization pressure (~25 GPa) at room temperature. These results will provide critical dynamic information for us to unders...

Disordered iron oxides as adsorbant for heavy metals: structural characterisation and reaction kinetics

Monica DAPIAGGI · Andrea BERNASCONI · Javier GAINZA MARTIN · Giorgia CARIATI · y 1 más

Iron oxides can be used for the removal of heavy metals from contaminated water-based solutions of various origin. They seem to be efficient (particularly when the grain size is in the nano-region), with a good retention behaviour. They can be produced from metallic scrap materials, and be re-used in the steel industry...

Pressure-induced valence changes as origin of magnetism loss in Ce2Pd2In

Jiri PRCHAL · Angelika ROSA · Petr KRÁL · Daniel STAŠKO

The proposed experiment aims to investigate the pressure-evolution of cerium valence in Ce2Pd2In intermetallic compound. Application of pressure was found to result in suppression of long-range magnetic order at pc ≈ 4 GPa accompanied by the Kondo anomaly formation. Pressure was found to result in formation of Ce-atomi...

Development and characterization of a Cre/loxP toolkit for genome engineering in Komagataella phaffii

Lili Song · Li Hua · Yanyan Wu · Xinyu Jiang · y 3 más

The Cre/loxP system is a versatile tool for genome engineering, yet its application in the industrial yeast Komagataella phaffii has been limited primarily to marker recycling. This study reports a comprehensive Cre/loxP toolkit for K. phaffii. The N-terminal SV40 NLS fusion (NLS-Cre) was identified as the optimal expr...

State-specific respiratory signatures for affective and stress recognition: Interpretable respiratory markers, autocorrelation lags, and compact CNN models

Andrei Velichko · Mehmet Tahir Huyut

Respiratory activity is a direct and interpretable physiological channel for wearable stress and affective-state recognition, yet many studies emphasize classification accuracy without identifying which respiratory properties separate different states. This work reframes RESP-based recognition as a joint predictive and...

Just infinite quotients of finitely generated subgroups of PL+[0,1]

Yash Lodha

We show that just infinite quotients of finitely generated subgroups of Richard Thompson's group F are virtually abelian, answering a question of Grigorchuk. We show the same holds for the group of piecewise linear orientation preserving homeomorphisms of the interval, and the group of piecewise projective homeomorphis...

Ferric Iron in serpentinites as proxy for abiotic H2 production

Valerio CERANTOLA · Malaspina NADIA · Olivier MATHON · Francesco RESSICO

Serpentinization is considered as among the most important processes sustaining redox conditions suitable for the synthesis of natural H2 and abiotic CH4. This process is documented at mid ocean ridges but also occur in subduction zones. In the latter context the potential for serpentinization to generate natural H2 an...

The Lp-continuity of wave operators for fractional order Schrödinger operators

M. Burak Erdoğan · Michael Goldberg · William R. Green

We consider fractional Schrödinger operators $H=(-Δ)^α+V(x)$ in $n$ dimensions with real-valued potential $V$ when $n>2α$, $α>1$. We show that the wave operators extend to bounded operators on $L^p(\mathbb R^n)$ for all $1\leq p\leq\infty$ under conditions on the potential that depend on $n$ and $α$ analogously to the...

Extracellular vesicles with unique proteomic signatures from self-organized cardiac spheroids under hydrodynamic stimulation

J.E. Perez · P. Joanne · L. Dec · D. Loew · y 2 más

Cardiac extracellular vesicles (EVs) hold promise as cell-free therapeutics for heart repair. However, robust methods to produce scalable, functional and cardiac-specific EVs at high yield remain a limiting factor in their exploitation. Here, we report an engineered platform that combines 3D cardiac microtissues with h...

Model-robust Inference for Seamless Ii/iii Trials with Covariate Adaptive Randomization

Yi, Kun · Xia, Lucy

Seamless phase II/III trials have become a cornerstone of modern drug development, offering a means to accelerate evaluation while maintaining statistical rigor. However, most existing inference procedures are model-based, designed primarily for continuous outcomes, and often neglect the stratification used in covariat...
