Journal of Field Robotics, EarlyView.ABSTRACT Time‐correlated single‐photon counting (TCSPC) lidar enables high‐resolution 3D imaging at kilometer range. While previous works have covered long range TCSPC 3D imaging from either stationary or airborne platforms, this is, to the best of our knowledge, the first attempt that use a moving ground vehicle. Fusing measurements taken at different

Annals of Applied Biology, EarlyView.We investigated the role of vision in host‐seeking behaviour by Philaenus spumarius, the main European vector of Xylella fastidiosa, through an integrated anatomical, optical, physiological, and behavioural study. Our data highlight that the spittlebug uses visual cues, including polarized light, which may aid in detecting the polarized reflections ...

Re-testing the JET-X Flight Module No. 2 at the PANTER facility
, 2014 The Joint European X-ray Telescope (JET-X) was the core instrument of the Russian Spectrum-X-gamma space observatory. It consisted of two identical soft X-ray (0.3 - 10 keV) telescopes with focusing optical modules having a measured angular resolution of

Multiwavelength Study of a Hyperluminous X-Ray Source near NGC 6099: A Strong IMBH Candidate
The Astrophysical JournalWe report on the intriguing properties of a variable X-ray source projected at the outskirts of the elliptical galaxy NGC 6099 ( d ≈ 139 Mpc). If truly located near NGC 6099, this is a hyperluminous X-ray source that reached an X-ray luminosity L _X ...

Emerging Techniques in Minimally Invasive Surgery in Hematologic Malignancies
European Journal of Haematology, EarlyView.ABSTRACT Hematologic malignancies represent the most common cancers in children. While the mainstays of treatment are chemotherapy and potentially hematopoietic stem cell transplant, minimally invasive surgery (MIS) has a role in the diagnosis and management of complications related both to disease and therapy as well as common pediatric surgical ...

X-Ray and Optical Polarization Aligned with the Radio Jet Ejecta in GX 339–4
The Astrophysical Journal LettersWe present the first X-ray polarization measurements of GX 339–4. IXPE observed this source twice during its 2023–2024 outburst, once in the soft-intermediate state and again during a soft state.
