Investigation of tantalum films growth for coplanar resonators with internal quality factors above ten million
Alpha-tantalum on silicon is a promising platform for high-coherence superconducting quantum circuits. However, the growth mechanism of alpha-tantalum on silicon remains poorly understood. We present a comprehensive study on alpha-tantalum films growth on various substrate. The decisive role of a substrate material Debye temperature on phase selection mechanism in tantalum films growth is experimentally confirmed, contradicting the prior assumptions on substrate temperature influence. Crucially…

"The TSA has an important job to do. Their actions at airports have been very poor. This creates lots of loss to travelers – waste. And their actions show a disrespect for people and the risks that exist. The security theater is not what we need. We need evidence based security measure while maintaining a focus on the value stream of people flying."

Magnetic force microscopy versus scanning quantum-vortex microscopy: Probing pinning landscape in granular niobium films
We provide an overview of the methodology and fundamental principles associated with newly developed experimental technique -- scanning quantum-vortex microscopy [Hovhannisyan et al., Commun. Mater., vol. 6, 42 (2025)]. This approach appears promising for experimental studies of vortex pinning phenomena in superconducting films and nanodevices. In particular, we studied the magnetic properties of magnetron-sputtered niobium (Nb) films by low-temperature magnetic force microscopy. As the tempera…

HiPrFlame-An ab initio based real-fluid modeling approach for high-pressure combustion-I. Rationale, methodology, and application to laminar premixed flames
High-pressure combustion is central to modern propulsion and power-generation systems, where operating pressures often exceed the critical point of working fluids, resulting in pronounced real-fluid effects that fundamentally alter thermodynamic and transport properties.

Low-temperature-compatible iron garnet films grown by liquid phase epitaxy
Single-crystalline yttrium iron garnet (YIG) thin films (< 100 nm) form the backbone of magnonics, owing to the record-low losses affecting their magnetization dynamics. However, thin epitaxial YIG has mostly been investigated under ambient temperatures, limited by the paramagnetic losses occurring at low temperatures due to the gadolinium gallium garnet (GGG) substrates required for epitaxial growth. Driven by a growing interest in magnonic devices that can operate in cryogenic conditions and …

Non-convergence of the principal eigenvalue of elliptic operators for large advection
This paper investigates the limit of the principal eigenvalue $λ(s)$ as $s\to+\infty$ for the following elliptic equation \begin{align*} -Δφ(x)-2s\mathbf{v}\cdot\nablaφ(x)+c(x)φ(x)=λ(s)φ(x), \quad x\in Ω \end{align*} in a bounded domain $Ω\subset \mathbb{R}^d (d\geq 1)$ with the Neumann boundary condition. Previous studies have shown that under certain conditions on $\mathbf{v}$, $λ(s)$ converges as $s\to\infty$ (including cases where $\lim\limits_{s \to\infty }λ(s)=\pm\infty$). …

Reviving Cultural Heritage: A Novel Approach for Comprehensive Historical Document Restoration
Historical documents represent an invaluable cultural heritage, yet have undergone significant degradation over time through tears, water erosion, and oxidation. Existing Historical Document Restoration (HDR) methods primarily focus on single modality or limited-size restoration, failing to meet practical needs. To fill this gap, we present a full-page HDR dataset (FPHDR) and a novel automated HDR solution (AutoHDR). Specifically, FPHDR comprises 1,633 real and 6,543 synthetic images with chara…

Here’s a mind-blowing experiment that you can try at home:
Gather some children’s blocks and place them on a table.
Take one block and slowly push it over the table’s edge, inch by inch, until it’s on the brink of falling.
If you possess patience and a steady hand, you should be able to balance it so that exactly half of it hangs off the edge.
Nudge it any farther, and gravity wins.
Now take two blocks and start over.
Stacking one on top of the other, how…
