Hey! Just a quick snap from today's walk (okay about 4:30h) near #kirchseeon and #ebersberg.
It's been warm but really beautiful. A lot of shade, quite some old trees, lots of green 😊
I'm curious how the photos will turn out. - Now I'm thinking about tomorrow's a…

Robust and Symmetric Magnetic Field Dependency of Superconducting Diode Effect in Asymmetric Dirac Semimetal SQUIDs
The recent demonstration of the superconducting diode effect (SDE) has generated renewed interests in superconducting electronics in which devices such as compact superconducting diodes that can perform signal rectification where low-energy operations are needed. In this article, we present our results of robust and symmetric-in-magnetic-field SDE in asymmetric superconducting quantum interference devices (SQUIDs) realized in high-quality Dirac semimetal Cd3As2 thin film grown by the molecular …

Parameterization and benchmarking of the Modified Marrone-Treanor Model for five-species air
We present updated parameters for five-species air to be used with the Modified Marrone-Treanor (MMT) air dissociation model. The vibrational relaxation and chemical reaction rates are derived from quasiclassical trajectory calculation (QCT) and direct molecular simulation (DMS) using ab initio potential energy surfaces (PESs). The resulting model and parameter set enable efficient computational fluid dynamics (CFD) simulations of high-temperature nonequilibrium five-species air (N2, O2, NO, N …

On the Efficient Discovery of Maximum $k$-Defective Biclique
The problem of identifying the maximum edge biclique in bipartite graphs has attracted considerable attention in bipartite graph analysis, with numerous real-world applications such as fraud detection, community detection, and online recommendation systems. However, real-world graphs may contain noise or incomplete information, leading to overly restrictive conditions when employing the biclique model. To mitigate this, we focus on a new relaxed subgraph model, called the $k$-defective biclique…

Vibrational properties of epitaxial graphene buffer layer on silicon carbide
The vibrational properties of semiconducting graphene buffer layer epitaxially grown on hexagonal silicon carbide are determined using first-principles calculations on a realistic structural model. Despite the important chemical and structural disorder associated with the partial covalent bonding with the substrate, the buffer-layer carbon atoms still display quasidispersive phonons mimicking those of graphene. The related frequency softening and broadening provide a natural interpretation of t…

The Trump administration found
“no viable path” forward
to complete California’s high-speed rail project
following a nearly four-month investigation that jeopardizes
$4 billion in federal funding.
In a 310-page compliance review released Wednesday,
the Department of Transportation cited budget shortfalls,
missed deadlines and a misleading projected ridership to connect San Francisco to Los Angeles via fast rail.
The review targets federal gran…
