Geometric Characterization of LEO–GEO Inter‐Satellite Links for Bidirectional Communications

International Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT Incorporating geosynchronous Earth orbit (GEO) and low Earth orbit (LEO) satellites can extend communication services far beyond the reach of terrestrial infrastructure. A key enabler of such architectures is the establishment of inter‐satellite links (ISLs) between LEOs and GEOs to support bidirectional communications.

Astronomical Quantum Optics with Extremely Large Telescopes

, 2006
Modern optics focuses on photonics and quantum optics, studying individual photons, and statistics of photon streams. Those can be complex and carry information beyond that recorded by imaging, spectroscopy, polarimetry, or interferometry. Since [almost]

Cost of Equipping First‐Level Hospitals for Children's Surgical Care in Low‐ and Middle‐Income Countries

World Journal of Surgery, EarlyView.
The Global Initiative for Children's Surgery (GICS) developed the Optimal Resources for Children's Surgical Care (ORECS) recommendations to address disparities in access to high‐quality children's surgery in low‐ and middle‐income countries (LMICs). However, the cost of adequately equipping these hospitals is currently unknown, creating a barrier for ...

Changes in the transition from cannabis use to use disorder by decade of first use: Findings from the Australian National Mental Health and Wellbeing surveys

Addiction, EarlyView.
Abstract Background and aims As cannabis becomes increasingly accessible and products more potent, it is critical that we understand how this may impact the risk of transitioning from cannabis use to cannabis use disorder (CUD). We aimed to examine whether the risk and speed of transition from cannabis use to CUD differ by decade of first cannabis use.

How to Do a Laparoscopic Iliac Lymph Node Biopsy Under Indocyanine Green (ICG) Guidance

ANZ Journal of Surgery, EarlyView.
ABSTRACT Isolated abdominal lymphadenopathy can be difficult to diagnose when lesions are inaccessible to percutaneous biopsy. We describe a laparoscopic common iliac lymph node biopsy performed using indocyanine green (ICG) fluorescence guidance. A 67‐year‐old woman with bilateral lower limb oedema was found to have an FDG‐avid right common iliac ...
