Boiling oceans and compressional tectonics on emerging ocean worlds - Nature Astronomy
Several moons in the outer Solar System have oceans encased beneath an ice shell. If the ice shell thins, ocean pressure decreases. Modelling shows that on Mimas, Enceladus, and Miranda, the ocean can boil. On larger bodies, instead, compressional forces form tectonic features.

Aerodynamic performance and robustness of a nature-inspired concept for a micro-scale wind turbine
We present direct numerical simulations of a novel concept for a micro-scale wind turbine, inspired in the mechanics of the auto-rotation of winged seeds. In this nature-inspired concept the turbine blades have two degrees of freedom: the pitch and the elevation (or coning) angles. These allow the blade to vary its attitude with respect to the incoming velocity seen by the blade (i.e., the tip-speed ratio, $λ$). In order to validate this new concept, we perform numerical simulations of the cou…

Sometimes you have a #dream that leaves you pondering. This time the middle segment involved freeing a certain harmless creature. It wasn't imprisoned in a physical jail but rather barred from leaving by another stronger creature. I've said that I'll keep said guardian busy for half an hour, so the victim could escape. The guardian turned out demonic in nature, and turned into an iron C-shaped bracket that tightened against my right side painfully. So my fight was mostly an attempt to get it off me, or at least stop it from tightening even more.

Utilizing such curved spacetime analogues as quantum batteries, we explore how the black hole scrambling affects charging via controlled quenches of preset scrambling parameters.

We study the optimal dynamic pricing of an expiring ticket or voucher, sold by a time-sensitive seller to strategic buyers who arrive stochastically with private values. The expiring nature creates a conflict: the seller's urgency to sell before expiration drives price reductions, which in turn incentivize buyers to wait. We seek the seller's optimal pricing policy that resolves this tension. The main analytical challenge is that buyer type is two-dimensional (valuation and arrival time), which…

The quantum XY chain with boundary fields: finite-size gap and phase behavior
We present a detailed study of the finite-size one-dimensional quantum XY chain in a transverse field in the presence of boundary fields coupled with the order-parameter spin operator. We consider fields located at the chain boundaries that have the same strength and that are oppositely aligned. We derive exact expressions for the gap $Δ$ as a function of the model parameters for large values of the chain length $L$. These results allow us to characterize the nature of the ordered phases of th…

Emergent Isotropic-Nematic Transition in 3D Semiflexible Active Polymers
Active semiflexible filament collectives, ranging from motor-driven cytoskeletal filaments to slender organisms such as cyanobacteria and worm aggregates, abound in nature, yet how activity and flexibility jointly govern their organization, especially Isotropic-nematic (I-N) transition, remains poorly understood. Using large-scale Brownian dynamics simulations of 3D active semiflexible polymers with varying flexibility degrees, we show that tangential active forces systematically shift the I-N …

Sonnet 109 - CIX
O! never say that I was false of heart,
Though absence seem'd my flame to qualify,
As easy might I from my self depart
As from my soul which in thy breast doth lie:
That is my home of love: if I have ranged,
Like him that travels, I return again;
Just to the time, not with the time exchanged,
So that myself bring water for my stain.
Never believe though in my nature reigned,
All frailties that besiege all kinds …

Death of the Novel(ty): Beyond n-Gram Novelty as a Metric for Textual Creativity

Death of the Novel(ty): Beyond n-Gram Novelty as a Metric for Textual Creativity
N-gram novelty is widely used to evaluate language models' ability to generate text outside of their training data. More recently, it has also been adopted as a metric for measuring textual creativity. However, theoretical work on creativity suggests that this approach may be inadequate, as it does not account for creativity's dual nature: novelty (how original the text is) and appropriateness (how sensical and pragmatic it is). We investigate the relationship between this notion of creativity …

Dark-fringe interferometer with dynamic phase control for Mössbauer science
Interference is a powerful tool for measuring and control. In Mössbauer science, interference effects are essential to most applications, due to the coherent scattering nature. However, Mössbauer interferometry remains challenging, due to stability requirements imposed by the short x-ray wavelength. Here, we put forward a ``dark fringe'' interferometer with vanishing transmission in the empty state, thereby facilitating sensitive measurements. The relative interferometer phase can dynamically…

Not My Agent, Not My Boundary? Elicitation of Personal Privacy Boundaries in AI-Delegated Information Sharing
Aligning AI systems with human privacy preferences requires understanding individuals' nuanced disclosure behaviors beyond general norms. Yet eliciting such boundaries remains challenging due to the context-dependent nature of privacy decisions and the complex trade-offs involved. We present an AI-powered elicitation approach that probes individuals' privacy boundaries through a discriminative task. We conducted a between-subjects study that systematically varied communication roles and delegat…

World-Env: Leveraging World Model as a Virtual Environment for VLA Post-Training
Vision-Language-Action (VLA) models trained via imitation learning suffer from significant performance degradation in data-scarce scenarios due to their reliance on large-scale demonstration datasets. Although reinforcement learning (RL)-based post-training has proven effective in addressing data scarcity, its application to VLA models is hindered by the non-resettable nature of real-world environments. This limitation is particularly critical in high-risk domains such as industrial automation,…

Design Exploration of AI-assisted Personal Affective Physicalization
Personal Affective Physicalization is the process by which individuals express emotions through tangible forms to record, reflect on, and communicate. Yet such physical data representations can be challenging to design due to the abstract nature of emotions. Given the shown potential of AI in detecting emotion and assisting design, we explore opportunities in AI-assisted design of personal affective physicalization using a Research-through-Design method. We developed PhEmotion, a tool for embed…

Most National Park Service sites will be “closed completely to public access”
during a government shutdown, according to the service’s contingency plan.
“Areas that by their nature are physically accessible to the public will face significantly reduced visitor services,”
according to the plan, which was published in March 2024.
It adds that the public will be asked not to visit national parks for the duration of a shutdown.

What Travelers Need to Know About the Possible Government Shutdown
A federal work stoppage could bring longer lines at the airport, national park closures, and significant losses in tourism revenue.

As you know, an important part of every nature education trail is a sudden "no entry" sign past the second kilometre.

Zero-Effort Image-to-Music Generation: An Interpretable RAG-based VLM Approach
Recently, Image-to-Music (I2M) generation has garnered significant attention, with potential applications in fields such as gaming, advertising, and multi-modal art creation. However, due to the ambiguous and subjective nature of I2M tasks, most end-to-end methods lack interpretability, leaving users puzzled about the generation results. Even methods based on emotion mapping face controversy, as emotion represents only a singular aspect of art. Additionally, most learning-based methods require …

Solar and Wind Power Forecasting: A Comparative Review of LSTM, Random Forest, and XGBoost Models
Rising global energy demand from population growth raises concerns about the sustainability of fossil fuels. Consequently, the energy sector has increasingly transitioned to renewable energy sources like solar and wind, which are naturally abundant. However, the periodic and unpredictable nature of these resources pose significant challenges for power system reliability. Accurate forecasting is essential to ensure grid stability and optimize energy management. But due to the high variability in…

Stochastic analysis of ultra-high energy cosmic ray interactions
Photonuclear interactions between ultra-high-energy cosmic ray (UHECR) nuclei and surrounding photon fields are key to understanding the connection between the compositions observed at Earth and those emitted from the sources. These interactions can completely disintegrate a nucleus of iron over trajectory lengths of a few and up to hundreds of megaparsecs, depending on the energy of the UHECR. The stochastic nature of these interactions means that it is not possible to describe them determinis…

Dynamic Dual-level Defense Routing for Continual Adversarial Training
As adversarial attacks continue to evolve, defense models face the risk of recurrent vulnerabilities, underscoring the importance of continuous adversarial training (CAT). Existing CAT approaches typically balance decision boundaries by either data replay or optimization strategy to constrain shared model parameters. However, due to the diverse and aggressive nature of adversarial examples, these methods suffer from catastrophic forgetting of previous defense knowledge after continual learning.…

Leveraging Quantum Computing For Recourse-Based Energy Management Under PV Generation Uncertainty
The integration of distributed energy resources, particularly photovoltaic (PV) systems and electric vehicles (EVs), introduces significant uncertainty and complexity into modern energy systems. This paper explores a novel approach to address these challenges by formulating a stochastic optimization problem that models the uncertain nature of PV power generation and the flexibility of bi-directional EV charging. The problem is structured as a two-stage stochastic program with recourse, enabling…

Event-Driven Control via Sparsity-Promoting Regularization: A Rollout Approach with Performance Guarantees
This paper presents a controller design method aiming to balance control performance and actuation frequency. In this framework, actuation timings are determined in an event-driven manner, resulting in intermittent control actions. Control performance is measured by an infinite-horizon average cost, and input sparsity is promoted through actuation-rate regularization. Since the formulated optimal control problem has a combinatorial nature, we employ a rollout algorithm to find a suboptimal solu…
