On the Efficacy of Ocean Formation with a Primordial Hydrogen Atmosphere
It has been suggested that Earth's present water budget formed from oxidation reactions between its initial hydrogen-rich primordial atmosphere and its magma ocean. Here we examine this hypothesis by building a comprehensive atmosphere-magma ocean model. We find that water formation is unlikely for two reasons. First, any water formed from oxidation reactions in the magma ocean would quickly outgass because of the water-poor atmosphere above. Second, the top boundary layer of the magma ocean be…

Stairway to Success: Zero-Shot Floor-Aware Object-Goal Navigation via LLM-Driven Coarse-to-Fine Exploration
Object-Goal Navigation (OGN) remains challenging in real-world, multi-floor environments and under open-vocabulary object descriptions. We observe that most episodes in widely used benchmarks such as HM3D and MP3D involve multi-floor buildings, with many requiring explicit floor transitions. However, existing methods are often limited to single-floor settings or predefined object categories. To address these limitations, we tackle two key challenges: (1) efficient cross-level planning and (2) z…

MLOps with Microservices: A Case Study on the Maritime Domain
This case study describes challenges and lessons learned on building Ocean Guard: a Machine Learning-Enabled System (MLES) for anomaly detection in the maritime domain. First, the paper presents the system's specification, and architecture. Ocean Guard was designed with a microservices' architecture to enable multiple teams to work on the project in parallel. Then, the paper discusses how the developers adapted contract-based design to MLOps for achieving that goal. As a MLES, Ocean Guard emplo…

Ultra-lightweight multi-functional gyroid-based metamaterial for simultaneous sound insulation, vibration suppression, and impact mitigation in all directions
Multi-functional materials are increasingly essential in many applications due to their ability to serve multiple purposes, simultaneously. Metamaterials can offer tailored functionality based on carefully designed tessellating basic building blocks, or unit cells, in space. These unit cells are most commonly designed for a single objective, for example, to mitigate an impact, insulate sound, or dampen vibrations. However, a metamaterial that can mitigate impact, attenuate elastic vibrations, i…

What is Past is Prologue:
#Paleoclimate constraints on #ECS Equilibrium #ClimateSensitivity #GreenhouseGas sensitivity of Earth's #Climate
First of 3 papers this summer.
My career trajectory has been building towards using past climate archives to narrow the possibilities of future climate. But it is HARD. And computationally expensive.
The next two papers of this project will rule out some high and low sensitivity simulations using Past Climate (Proxy) archives and Data Assimilation. Those should be out in preprint in the next couple of months.
We hope this project (first to constrain earth climate sensitivity using coupled atmosphere-ocean earth system models) will be streamlined in the future and applied widely.
