O Miguel Sousa Tavares estš cada vez mais idiota.
Os "helicópteros bons" que demos Š Ucrânia eram os Kamov, que não voavam porque não tinham autorização de voo porque não tinham quem lhes fizesse manutenção, pelo menos um estava mesmo avariado, e da última vez que soube deles (jš foi hš algum tempo; as coisas podem ter mudado entretanto) continuavam em Portugal porque a Ucrânia os aceitou e agradeceu mas diz que para jš não tinha como pô-los em condições.

Miguel Sousa Tavares: “Os helicópteros bons que tínhamos demos à Ucrânia, para ajudar à guerra, e agora não os temos para combater os fogos”
O cronista do Expresso fala dos fogos que têm assolado o país e remata: “Não sei o que é que o PSD e Luís Montenegro vão festejar no Pontal”, na festa desta quinta-feira que marca o final das férias políticas. Trump é omnipresente no episódio desta semana

Ich fordere übrigens überhaupt nicht, nach Australien zu Fuß zu laufen oder zu schwimmen, ich möchte nur ein so gut ausgebautes Schienennetz, das zudem auch mit sinnvollen und schnellen Verbindungen gefahren wird, daß sich Strecken von 1000km sinnvoll mit der Bahn zurücklegen lassen.

Average solar active region: I. Intensities, velocities, and the photospheric magnetic field
Context: Solar active regions (ARs) are key manifestations of the Sun's magnetic activity, displaying diverse spatial and temporal characteristics. Their formation and evolution play a crucial role in understanding the solar dynamo and space weather. While individual ARs exhibit significant variability, ensemble averaging offers a method to extract their typical properties and evolution. Aims: This study aims to construct an average bipolar AR using ensemble averaging of observational data. By …

The Potential Danger to Satellites due to Ejecta from a 2032 Lunar Impact by Asteroid 2024 YR4
On 2032 December 22 the 60 m diameter asteroid 2024 YR4 has a 4% chance of impacting the Moon. Such an impact would release 6.5 MT TNT equivalent energy and produce a ~1 km diameter crater. We estimate that up to 10^8 kg of lunar material could be liberated in such an impact by exceeding lunar escape speed. Depending on the actual impact location on the Moon as much as 10% of this material may accrete to the Earth on timescales of a few days. The lunar ejecta-associated particle fluence at 0.1 …

Digital Transformation of Urban Planning in Australia: Influencing Factors and Key Challenges
Over the past two decades, several governments in developing and developed countries have started their journey toward digital transformation. However, the pace and maturity of digital technologies and strategies are different between public services. Current literature indicates that research on the digital transformation of urban planning is still developing. Therefore, the aim of this study is to understand the influencing factors and key challenges for the digital transformation of urban pl…

Ultra-High-Energy Transient Source Search using IceCube Neutrinos and Pierre Auger Photon Candidates
The origins of ultra-high-energy particles remain one of the most profound mysteries in astrophysics. If nearby transient sources of ultra-high-energy particles exist, we might expect correlated emission of neutrinos and photons, arriving in close temporal and spatial coincidence. The IceCube Neutrino Observatory, located at the South Pole, is sensitive to neutrinos from TeV to EeV energies, while the Pierre Auger Observatory, in Argentina, detects cosmic rays and has the capability of observin…

Acting and Planning with Hierarchical Operational Models on a Mobile Robot: A Study with RAE+UPOM
Robotic task execution faces challenges due to the inconsistency between symbolic planner models and the rich control structures actually running on the robot. In this paper, we present the first physical deployment of an integrated actor-planner system that shares hierarchical operational models for both acting and planning, interleaving the Reactive Acting Engine (RAE) with an anytime UCT-like Monte Carlo planner (UPOM). We implement RAE+UPOM on a mobile manipulator in a real-world deployment…

SETI Post-Detection Futures: Directions for Technosignature Research and Readiness
This white paper highlights the work that is needed to anticipate the challenges and societal impacts of a possible technosignature detection. We recommend practical steps to strengthen NASA's astrobiology agenda, guided by the existing interdisciplinary framework of the SETI PostDetection Hub (est. 2022) at the University of St Andrews (Elliot et al. 2023), which emphasizes comprehensive preparedness across science, society, governance, and communication. NASA can significantly enhance readine…

Rotation Periods of Candidate Single Late-M Dwarfs in TESS
Recent studies suggest that the angular momentum evolution of late-M and brown dwarfs differs from the well-known spin-down evolution of hotter stars. Characterizing the distribution of rotation periods of these objects in the solar neighborhood can help elucidate this evolutionary pathway just above, at, and below the hydrogen burning limit. In this paper, we examine 399 candidate single late-M dwarfs with $G - G_{RP} \geq 1.4$ mag ($\gtrsim$M6) using TESS light curves. To determine rotation p…

FAUST XXVII: The circumbinary disk and the outflow of the L 1551 IRS 5 binary system
Using continuum and $\text{C}^{18}\text{O}\:(2-1)$ line data obtained from the large ALMA program FAUST, we studied the structure of the protostellar binary system L1551 IRS5 at scales between 30 and 3,000 au to constrain its properties, from the circumstellar and circumbinary disks up to the envelope and outflow scales, which exhibits complex and entangled structures at the scales of its inner and outer envelopes, presumably caused by the influence of the central binary. Assuming a dust-to-gas…
