1. Protoplanetary cores drove chondrule formation 

   Ali-Dib, Mohamad; Walton, Craig (2025)

   MONTHLY NOTICES OF THE ROYAL ASTRONOMICAL SOCIETY

   Chondrules are small spherical objects that formed at high temperatures early in the history of the Solar System. The key compositional characteristics of chondrules may be well explained by high gas pressures in their formation environment. However, such high gas pressures are widely considered astrophysically unreasonable. Here, we propose that chondrules were formed via the processing of dust grains in the dust-rich envelopes of planetary ...

2. Regularity of Unconstrained <i>p</i>-harmonic Maps from Curved Domain and Application to critical <i>p</i>-Laplace Systems 

   Martino, Dorian (2025)

   POTENTIAL ANALYSIS

   Given p >= 2 and a map g:Bn(0,1)-> Sn++, where Sn++ is the group of positively definite matrices, we study critical points of the following functional: v is an element of W1,pBn(0,1);RN integral Bn(0,1)|del v|gpdvolg=integral Bn(0,1)g alpha beta(x)partial derivative alpha v(x),partial derivative beta v(x)p2detg(x)dx. We show that if g is uniformly close to a constant matrix, then v is locally H & ouml;lder-continuous. If g is H & ...

3. Understanding the Structure of Protonated Box Ligands: Insights from Spectroscopy and Computational Studies 

   Gorbachev, Vladimir; van Tetering, Lara; Martens, Jonathan; et al. (2025)

   Helvetica Chimica Acta

   Protonation and tautomerization significantly impact the conformational landscape and non-covalent interactions in bis(oxazoline) (BOX) ligands, which are crucial for their applications in catalysis. These interactions influence properties such as binding affinity and catalytic efficiency. While tautomerization has been reported for neutral BOX ligands, its role in protonated forms remains less understood. Here we report the structural ...

4. Geography for AI sustainability and sustainability for GeoAI 

   Shi, Meilin; Janowicz, Krzysztof; Verstegen, Judith; et al. (2025)

   Cartography and Geographic Information Science

   Recent years have witnessed a boom in the development of multimodal large-scale generative AI models. These computationally intensive AI models, such as GPT-4, and their associated data centers have undergone increasing scrutiny in terms of their energy consumption and carbon emissions. As awareness of the energy costs and carbon footprints of AI models grows, attention has broadened to include other sustainability-related aspects such ...

5. Integrating the Bright and Dark Sides of Aquatic Resource Subsidies-A Synthesis 

   Twining, Cornelia W.; Blanco, Andreu; Dutton, Christopher; et al. (2025)

   Ecology Letters

   Aquatic and terrestrial ecosystems are linked through the reciprocal exchange of materials and organisms. Aquatic-to-terrestrial subsidies are relatively small in most terrestrial ecosystems, but they can provide high contents of limiting resources that increase consumer fitness and ecosystem production. However, they also may carry significant contaminant loads, particularly in anthropogenically impacted watersheds. Global change processes, ...
