SpeedAug: Policy Acceleration via Tempo-Enriched Policy and RL Fine-Tuning
Announce Type: replace Abstract: Robotic policy learning for complex real-world manipulation tasks has seen rapid recent progress, enabled in large part by the ability to collect demonstrations through human operation. However, policies trained from such demonstrations often execute tasks far more slowly than the robot's physical capabilities, as demonstration data is collected under practical constraints that favor conservative, success-oriented trajectories over execution speed. Existing...
Scalable Bayesian Inference for Nonlinear Conservation Laws
arXiv:2605.31127v1 Announce Type: new Abstract: Nonlinear conservation laws are at the heart of many of the most important dynamical systems in science and engineering. In practical applications, such systems are often subject to various sources of uncertainty, e.g. due to sparse or noisy measurements. Inferring physical quantities and fields of interest then becomes an ill-posed problem which both classical numerical methods and modern deep learning-based methods struggle to treat...
Wading bird populations in the New York–New Jersey Harbor are in decline
Wading bird populations in the New York–New Jersey Harbor are in decline Stephanie Baum Scientific Editor Robert Egan Associate Editor Urban estuaries can support thriving ecosystems despite bustling human activity. Noting that bird populations can serve as a key indicator of environmental health, researchers recently investigated trends in the New York–New Jersey Harbor, home to the largest breeding population of colonial nesting wading birds (herons, egrets, ibises) in the northeastern...
Hierarchical Forecast Reconciliation for Urban Rail Transit Demand Prediction under Operational Disruptions
Announce Type: new Abstract: Accurate and coherent passenger demand forecasting is essential for Urban Rail Transit (URT) operations. Passenger demand has a hierarchical structure in which origin-destination (OD) flows aggregate to station-level inflows and outflows through conservation constraints. In practice, station-level and OD-level forecasts are often generated independently, producing incoherent predictions that violate these constraints and introduce inconsistencies into operational...
On the Complexity of Offline Reinforcement Learning with $Q^\star$-Approximation and Partial Coverage
Announce Type: replace Abstract: We study offline reinforcement learning under $Q^\star$-approximation and partial coverage, a setting that motivates practical algorithms such as Conservative $Q$-Learning (CQL; Kumar et al., 2020) but has received limited theoretical attention. Our work is inspired by the following open question: "Are $Q^\star$-realizability and Bellman completeness sufficient for sample-efficient offline RL under partial coverage?" We answer in the negative via an...
Reconnecting the last wild landscapes of the Javan leopard
Reconnecting the last wild landscapes of the Javan leopard Lisa Lock Scientific Editor Andrew Zinin Lead Editor Research from the University of Twente shows how the Javan leopard, one of the world's rarest big cats, survives on one of the most crowded islands on Earth. Using camera traps and spatial models, Andhika Chandra Ariyanto, a doctoral researcher at ITC, found that the cat depends on a wide range of prey and on recovering forests as much as on the protected reserves that conservation...
How a Citizen Science Organization Aims to Preserve the Places It Brings Tourists to Study
Deep in the Peruvian Amazon, the Tamshiyacu Tahuayo Regional Conservation Area boasts enormous biodiversity—pink dolphins, rare monkeys, giant river otters, reptiles, and hundreds of birds and different types of plants. It’s also one of the most prominent examples of a government recognizing that environmental conservation doesn’t require keeping people out. That instead, it’s possible for humans to coexist with nature and help protect it.
Ocean conservation needs strong relationships, not just targets
Ocean conservation needs strong relationships, not just targets Lisa Lock Scientific Editor Andrew Zinin Lead Editor With World Oceans Day coming up on June 8, policymakers and researchers will be thinking about the state of the ocean and efforts to protect marine environments. There is no shortage of global objectives and targets to drive those conversations. The United Nations Decade of Ocean Science for Sustainable Development (2021–30) has advanced 10 challenges to drive action.
CERTIFY-ED: A Multi-Layer Verification Framework for Exact Diagonalization of Quantum Many-Body Systems
arXiv:2605.11787v2 Announce Type: replace-cross Abstract: Exact diagonalization (ED) is a workhorse technique in computational quantum many-body physics, but published ED results are rarely accompanied by machine-checkable evidence of their numerical correctness. The community typically relies on the implicit trust chain LAPACK $\to$ user code $\to$ result, with at most informal agreement against another package treated as confirmation. We argue that this practice is inadequate for a method...
Corals have a hormonal clock and it looks surprisingly like ours
Corals have a hormonal clock and it looks surprisingly like ours Gaby Clark Scientific Editor Robert Egan Associate Editor A three-year study has cracked open the hidden biology behind coral reproduction, revealing hormone cycles that echo those of humans and other animals, and a new way to detect reef distress before it's too late. Once a year, on cue, corals across a reef release their eggs and sperm into the sea simultaneously. Coral reproduction is one of nature's most spectacular events.
