Unraveling the Molecular Mechanisms of Glioma Recurrence: A Study Integrating Single‐Cell and Spatial Transcriptomics

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Glioma recurrence severely impacts patient prognosis, with current treatments showing limited efficacy. Traditional methods struggle to analyze recurrence mechanisms due to challenges in assessing tumor heterogeneity, spatial dynamics, and gene networks.

First Observation of Ionospheric Plasma Bubble Signatures by Ca+ Lidar at Low Latitude

Geophysical Research Letters
Ionospheric plasma bubbles refer to density depletion structures in the ionosphere, which are usually seen in the electron density profiles observed by radar, and have never been observed in the density profiles of metallic ions.

Fermionic and Bosonic Stabilizing Effects for Type I and Type II Dimension Bubbles

, 2004
We consider two types of "dimension bubbles", which are viewed as 4d nontopological solitons that emerge from a 5d theory with a compact extra dimension. The size of the extra dimension varies rapidly within the domain wall of the soliton.

Homogeneous nucleation of quark-gluon plasma, finite size effects and long-lived metastable objects [PDF]

, 1998
The general formalism of homogeneous nucleation theory is applied to study the hadronization pattern of the ultra-relativistic quark-gluon plasma (QGP) undergoing a first order phase transition.

Innovative Processing of Compacted Waste Aluminum Alloy Powders via Controlled Remelting and Solidification

Advanced Engineering Materials, EarlyView.
This study demonstrates an efficient recycling route for out‐of‐spec AlSi10Mg atomized powders through compaction and arc remelting followed by suction casting. By correlating compaction load, cooling rate, and resulting microstructure, we show that intermediate pressures (50–80 kN) and rapid cooling refine dendrites, reduce porosity, and enhance ...

Packaging of Macroscopic Material Payloads: Needs, Challenges, Concepts, and Future Directions

Advanced Engineering Materials, EarlyView.
This review introduces a unified framework that decomposes any macroscopic packaging system into the payload, packaging material, and packaging strategy and combines them into a conceptual packaging equation: packaging strategy = payload + packaging material.

Multi-instrument observations of ionospheric super plasma bubbles in the European longitude sector during the 23–24 April 2023 severe geomagnetic storm

Journal of Space Weather and Space Climate
This study’s objective is to better specify the rare occurrence of super equatorial plasma bubbles in particular to the European longitude sector, detailing their spatio-temporal evolution, and better understanding pre-conditions for their development ...

Thermodynamic Pathways of Nonequilibrium Solidification in Wire‐Arc Additive Manufacturing Fe‐Based Multicomponent Alloy Structures

Advanced Engineering Materials, EarlyView.
Geometry‐driven thermal behavior in wire‐arc additive manufacturing (WAAM) influences microstructural evolution during nonequilibrium solidification of a chemically complex Fe–Cr–Nb–W–Mo–C nanocomposite system. By comparing different deposits configurations, distinct entropy–cooling rate correlations, segregation, and carbide evolution are revealed ...

Bubble evolution and fuzz formation in plasma-facing materials: from ridges to tendrils

Nuclear Fusion
Fuzz formation in plasma-facing materials remains insufficiently understood. We correlate subsurface helium-bubble evolution with surface morphological transitions in tungsten–rhenium (25 atomic %) exposed to high-flux, 90 eV He plasma at ∼1173 K ...

Occurrence of Equatorial Plasma Bubbles during Intense Magnetic Storms

International Journal of Geophysics, 2011
An important issue in low-latitude ionospheric space weather is how magnetic storms affect the generation of equatorial plasma bubbles. In this study, we present the measurements of the ion density and velocity in the evening equatorial ionosphere by the
