Modal Geometry Governs Proteoform Dynamics
A central mystery is how a specific proteoform, a distinct molecular variant of a protein, dynamically shapes its own future by evolving into new modes that exist only in potential until realised. Here, Modal Geometric Field (MGF) Theory couples real and abstract proteoform transitions through four axioms. Axioms one-three (invariant) dictate that only first-order transitions occur on the discrete, volume invariant, non symplectic modal manifold. Axiom four (mutable) functorially projects the g…

Cocoon-to-Butterfly Transformation in Protoplanetary Nebula: Detection of a Spherical Halo and a Barrel-shaped Torus in IRAS 06530$-$0213
Protoplanetary nebulae (PPNs) represent a critical evolutionary bridging stage between the asymptotic giant branch (AGB) and planetary nebula (PN) stages. Their dynamical structures provide key insights into late stellar evolution. Here, we report CO and $^{13}$CO imaging observations of the carbon-rich PPN IRAS 06530$-$0213, a source exhibiting the unidentified 21 micron emission band, conducted with the Northern Extended Millimeter Array (NOEMA). The CO maps reveal a spherical halo (diameter …

Mojo: MLIR-Based Performance-Portable HPC Science Kernels on GPUs for the Python Ecosystem
We explore the performance and portability of the novel Mojo language for scientific computing workloads on GPUs. As the first language based on the LLVM's Multi-Level Intermediate Representation (MLIR) compiler infrastructure, Mojo aims to close performance and productivity gaps by combining Python's interoperability and CUDA-like syntax for compile-time portable GPU programming. We target four scientific workloads: a seven-point stencil (memory-bound), BabelStream (memory-bound), miniBUDE (co…

Kollision mit der Erde vor 4,5 Milliarden Jahren: Theia war vorher ein Nachbar
Ein Protoplanet ist vor mehr als vier Milliarden Jahren in die Erde gestürzt und hat den Mond herausgeschlagen. Jetzt ist klar, woher der Protoplanet stammte.

Time-resolved protoplanetary disk physics in DQ Tau with JWST
Accretion variability is ubiquitous in YSOs. While large outbursts may strongly affect the disk, the effects of moderate bursts are less understood. We aim to study the physical response of the disk around the eccentric binary system DQ Tau to its periodic accretion changes. We organized a multi-wavelength campaign centered on four JWST/MIRI spectra. We targeted three periastrons (high accretion state) and one apastron (quiescence). We used optical and near-infrared spectroscopy and photometry …
