Supercritical subsurface fluids open a window into the world
Researchers have built on past studies and introduced new methods to explore the nature and role of subsurface fluids, including water, in the instances and behaviors of earthquakes and volcanoes. Their study suggests that water, even heavy rainfall, can play a role in or even trigger seismic events. This could potentially lead to better early warning systems.

Geometry over finite local rings: Rigidity and Isospectrality
We study the simplicial order complexes obtained from free modules over finite local rings. These complexes arise naturally as geodesic spheres in Bruhat-Tits buildings over non-archimedean local fields. We establish two forms of rigidity, showing that their automorphism groups arise from the underlying algebraic group, and that they are determined by sparse induced subgraphs. We compute the spectra of these subgraphs and show that they form excellent expanders, which results in expansion for g…

Bäume können beim Klimaschutz helfen, denn sie speichern Kohlendioxid. 🌲 Wälder schützen auch den Boden und fördern die Artenvielfalt. Aber Bäume wachsen langsam. Warum haben wir keine Zeit zu verlieren? Im Artikel ist erklärt, wie Treibhausgase wirken und wie wichtig Aufforstung ist.

Wiederaufforstung ist wichtig für den Klimaschutz (vereinfachte Sprache)
Wiederaufforstung kann ein wichtiger Baustein im Kampf gegen den Klimawandel sein. Wie Bäume CO2 binden und warum es wichtig ist, dass sie alt werden.

FAC-FACodec: Controllable Zero-Shot Foreign Accent Conversion with Factorized Speech Codec
Previous accent conversion (AC) methods, including foreign accent conversion (FAC), lack explicit control over the degree of modification. Because accent modification can alter the perceived speaker identity, balancing conversion strength and identity preservation is crucial. We present an AC framework that provides an explicit, user-controllable parameter for accent modification. The method targets pronunciation while preserving suprasegmental cues such as intonation and phoneme durations. Res…

Signal Protocol and Post-Quantum Ratchets
We are excited to announce a significant advancement in the security of the Signal Protocol: the introduction of the Sparse Post Quantum Ratchet (SPQR). This new ratchet enhances the Signal Protocol’s resilience against future quantum computing threats while maintaining our existing security guar...

Subcritical transition and multistability in liquid metal magnetoconvection with sidewalls
The motionless conducting state of liquid metal convection with an applied vertical magnetic field confined in a vessel with insulating side walls becomes linearly unstable to wall modes through a supercritical pitchfork bifurcation. Nevertheless, we show that the transition proceeds subcritically, with stable finite-amplitude solutions with different symmetries existing at parameter values beneath this linear stability threshold. Under increased thermal driving, the branch born from the linear…

A supercharacter analog of vanishing-off subgroups and generalized Camina pair
Vanishing-off subgroups, generalized Camina pair and other related subgroups have played a significant role in the study of group structure. The primary goal of this paper is to study their analogs in the setting of supercharacter theory. We establish several properties of these subgroups which includes connections with supercharacter theory products.

Modeling and Managing Temporal Obligations in GUCON Using SPARQL-star and RDF-star
In the digital age, data frequently crosses organizational and jurisdictional boundaries, making effective governance essential. Usage control policies have emerged as a key paradigm for regulating data usage, safeguarding privacy, protecting intellectual property, and ensuring compliance with regulations. A central mechanism for usage control is the handling of obligations, which arise as a side effect of using and sharing data. Effective monitoring of obligations requires capturing usage trac…
