Revealing accretion onto black holes: X-ray reflection throughout three outbursts of GX 339-4
, 2014 Understanding the dynamics behind black hole state transitions and the changes they reflect in outbursts has become long-standing problem. The X-ray reflection spectrum describes the interaction between the hard X-ray source (the power-law continuum) and

X-ray Spectral Formation in a Converging Fluid Flow: Spherical Accretion into Black Holes [PDF]
, 1997 We study Compton upscattering of low-frequency photons in a converging flow of thermal plasma. The photons escape diffusively and electron scattering is the dominant source of opacity.

MOFs and COFs in Electronics: Bridging the Gap between Intrinsic Properties and Measured Performance
Advanced Functional Materials, EarlyView.Metal‐organic frameworks (MOFs) and covalent organic frameworks (COFs) hold promise for advanced electronics. However, discrepancies in reported electrical conductivities highlight the importance of measurement methodologies. This review explores intrinsic charge transport mechanisms and extrinsic factors influencing performance, and critically ...

Journal of International Dispute Settlement, 2011 In this article, the author discusses various consequences of the softness of soft law. He acknowledges that the concept of soft law is useful for certain endeavours in international law, such as understanding the international law-making process and the politics behind the adoption of legal instruments.
