Location‐Assisted Graph‐Based User Scheduling in Multi‐User MIMO LEO NTN Systems

open access: yesInternational Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT This paper addresses user clustering and scheduling for multi‐user MIMO low Earth orbit nonterrestrial network systems in full frequency reuse. Since the number of on‐ground user terminals is usually much higher than the number of on‐board LEO satellite antennas, user scheduling becomes a fundamental task.

Mobilising Community Engagement in Disaster Risk‐Sensitive Urban Planning: Insights From Grounded Theory and Two‐Mode Social Network Analysis

open access: yesSustainable Development, EarlyView.
ABSTRACT Despite the emphasis in sustainable development goals (SDG) 11, 13, and 17 on collaborative efforts to address climate change‐induced disaster risks through inclusive planning, stakeholders' role in fostering community engagement in risk‐sensitive urban planning (RSUP) remains underexplored.

Upfront payments to venture‐backed startups in technology alliances: Bargaining effects of VC affiliations

open access: yesStrategic Entrepreneurship Journal, EarlyView.
Abstract Research Summary Upfront payments are important financial resources startups seek to negotiate in technology alliances. This study unpacks how venture‐backed startups can benefit from their VC affiliations and obtain better payments. We develop a bargaining framework and argue that VCs can strengthen venture‐backed startups' hand in alliance ...

Crossing and Anticrossing of Exchange‐Coupled Molecular Spin Excitation Energy Levels

open access: yesSmall, EarlyView.
Orientation matters: The excitation energy levels of exchange‐coupled spins of two nickelocene molecules anchored to superconducting electrodes are explored via inelastic electron tunneling spectroscopy. Depending on the tilt angle of the single‐molecule magnetic probe the levels cross or exhibit avoided crossing. Abstract The superconducting Pb tip of

Defect Engineering in Large‐Scale CVD‐Grown Hexagonal Boron Nitride: Formation, Spectroscopy, and Spin Relaxation Dynamics

open access: yesSmall, EarlyView.
The controlled formation of defects in large‐area CVD‐grown hBN using various irradiation methods is demonstrated. Defect type and properties depend on particle type (He+, Ne+, Ar+, neutrons, and electrons), substrate effects, and film thickness.
