MedComm, Volume 4, Issue 3, June 2023., 2023 The reversible and irreversible protein posttranslational modifications, such as acetylation, methylation, phosphorylation, ubiquitination, glycosylation, SUMOylation, and redox modifications, are essential regulators in organisms and cells. This work systematically summarizes the features, regulatory mechanisms, substrates, functions, and related ...

Electronics Letters, Volume 58, Issue 18, Page 684-686, August 2022., 2022 Abstract A two‐stage 920–960 MHz power amplifier (PA) in GaAs heterojunction bipolar transistor (HBT) process is demonstrated for small‐cell communications in the lunar environment. To cope with the temperature fluctuations during lunar days, a novel complementary to absolute temperature (CTAT) biasing scheme is proposed for the PA to achieve an ultra ...

Brain Pathology, Volume 32, Issue 4, July 2022., 2022 We studied the epigenomic landscape of intracranial mesenchymal tumor with FET‐CREB fusion, an emerging CNS tumor entity that occurs primarily in children and young adults. These tumors resolved into two epigenetic subgroups with divergent clinical outcomes that were distinct from meningiomas and all analyzed extracranial sarcomas.

Terra Nova, Volume 33, Issue 5, Page 502-510, October 2021., 2021 Abstract Fault‐ and fracture‐hosted multi‐stage mineral assemblages that formed by fracture reactivation and fluid migration, constitute archives of the tectonic evolution of Precambrian cratons. Complex intergrowth patterns of these mineral records often hinder absolute dating of mineralization events for geological models.

Homogeneous batch micro‐crystallization of proteins from ammonium sulfate
Acta Crystallographica Section D, Volume 77, Issue 2, Page 194-204, February 2021., 2021 This work demonstrates how the precipitating properties of ammonium sulfate can be exploited to drive the transition from vapour‐diffusion conditions to large‐scale batch micro‐crystallization and how the specific ammonium sulfate concentration can further be used to fine‐tune microcrystal size and size distribution.The emergence of X‐ray free‐electron
