Salt transport in artificial snow on sea ice: laboratory experiments Open
Salt within snowpacks on first-year sea ice affects snow properties by reducing the melting point, which can increase liquid water content and alter snowpack evolution. These changes lead to modifications in dielectric properties, which in…

Impact of surface melt and brine infiltration on fracture toughness of ice shelves Open
Ice shelves are heterogeneous composites of firn, meteoric ice, refrozen melt and brine-saturated ice. The properties and distribution of these elements control ice shelf response to stress and susceptibility to fracturing. Here, we quanti…

The Undrained Response of Westerly Granite Subjected to Cyclical Changes in Load Open
When subjected to changes in applied stress, the pore space of rocks elastically deforms, producing changes in internal pore pressure when the pore fluid is unable to flow in or out of the stressed volume. The magnitude of this effect depe…

Learning from Supervision with Semantic and Episodic Memory: A Reflective Approach to Agent Adaptation Open
We investigate how agents built on pretrained large language models can learn target classification functions from labeled examples without parameter updates. While conventional approaches like fine-tuning are often costly, inflexible, and…

Multi‐porous extension of anisotropic poroelasticity: Linkage with micromechanics Open
We attempt to formalise the relationship between the poroelasticity theory and the effective medium theory of micromechanics. The assumptions of these two approaches vary, but both can be linked by considering the undrained response of a m…

Multi‐porous extension of anisotropic poroelasticity: Consolidation and related coefficients Open
We propose the generalization of the anisotropic poroelasticity theory. At a large scale, a medium is viewed as quasi‐static, which is the original assumption of Biot. At a smaller scale, we distinguish different sets of pores or fractures…

Big City Bias: Evaluating the Impact of Metropolitan Size on Computational Job Market Abilities of Language Models Open
Large language models (LLMs) have emerged as a useful technology for job matching, for both candidates and employers. Job matching is often based on a particular geographic location, such as a city or region. However, LLMs have known biase…
