Optimized Kalman Filter based State Estimation and Height Control in Hopping Robots
Rotor-based hopping locomotion significantly improves efficiency and operation time as compared to purely flying systems; where most hopping robots use the liftoff states and an assumed ballistic trajectory to determine the hopping height. However, significant aerial phase force (e.g., thrust and drag) can invalidate this assumption and lead to poor estimation performance. To combat this issue, a group has implemented multiple sensors (active and passive optical, inertial, and contact) and sign…

US won't send some weapons pledged to Ukraine following a Pentagon review of military aid
A Pentagon review determined that stocks were too low on some weapons previously pledged to Ukraine,
so pending shipments of some items won’t be sent,
according to a U.S. official who spoke on condition of anonymity to provide information that has not yet been made public.

The Defense Department did not provide details on what specific weapons were being held back.

US won't send some weapons pledged to Ukraine following a Pentagon review of military aid
The U.S. is halting some shipments of weapons to Ukraine amid concerns that its own stockpiles have declined too much

Determining our future savings might be a bit difficult. At our old house I knew the cost of filling an oil tank a couple of times a year. That cost went to zero and my Hydro bill went up. Based on the savings I had a 7.5 year ROI on my upfront geothermal install cost. Now I'm in a new home (10 days today) with only monthly averages for Hydro and Enbridge provided by the real estate listing. But that should be enough data to give me an approximate estimate.

Binarity at LOw Metallicity (BLOeM): Pipeline-Determined Physical Properties of OB Stars
We aim to determine the physical properties of OB stars from the multi-epoch VLT/FLAMES BLOeM spectroscopic survey of the Small Magellanic Cloud. We apply a pipeline designed to analyse large spectroscopic samples of OB stars to the co-added, initial 9 epochs of the BLOeM survey, utilising grids of synthetic model spectra computed with the stellar atmosphere code FASTWIND. 69 OB stars are excluded from the analysis owing to disk emission or significant contamination by secondaries in SB2 binari…

An Offline Reinforcement Learning Algorithm Customized for Multi-Task Fusion in Large-Scale Recommender Systems
As the last critical stage of RSs, Multi-Task Fusion (MTF) is responsible for combining multiple scores outputted by Multi-Task Learning (MTL) into a final score to maximize user satisfaction, which determines the ultimate recommendation results. Recently, to optimize long-term user satisfaction within a recommendation session, Reinforcement Learning (RL) is used for MTF in the industry. However, the offline RL algorithms used for MTF so far have the following severe problems: 1) to avoid out-o…

Exploring the change in scientific readability following the release of ChatGPT
The rise and growing popularity of accessible large language models have raised questions about their impact on various aspects of life, including how scientists write and publish their research. The primary objective of this paper is to analyze a dataset consisting of all abstracts posted on arXiv.org between 2010 and June 7th, 2024, to assess the evolution of their readability and determine whether significant shifts occurred following the release of ChatGPT in November 2022. Four standard re…

Trump’s determination to move fast could slow implementation of his tariff regime.
It also threatens to cost him credibility with businesses he’s counting on to invest in the U.S.
and world leaders whose buy-in he needs to negotiate trade deals.
Still, few expect a different posture from the famously intransigent fool or any second-guessing following the Wednesday ruling from the U.S. Court of International Trade, which briefly halted most of the tariffs

Magnetocrystalline anisotropy of FeNi and FeCo along the Bain path
We theoretically investigate magnetic anisotropy in materials with non-critical elements to determine which symmetry conditions and atomic shell filling favor enhanced magnetic anisotropy. We study the magnetocrystalline anisotropies (MCA) of the equiatomic ferrous compounds FeCo and FeNi using ab initio calculations and analytical approaches via the diatomic pair model. We find that when these materials undergo a Bain transformation, that is, the variation of the a and c lattice parameters adj…
