A temperature‐compensated linear GaAs HBT power amplifier for small‐cell applications in −25 to 125∘C$^\circ \rm C$ lunar environment

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 ...

Intracranial mesenchymal tumors with FET‐CREB fusion are composed of at least two epigenetic subgroups distinct from meningioma and extracranial sarcomas

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.

Reconstructing craton‐scale tectonic events via in situ Rb‐Sr geochronology of poly‐phased vein mineralization

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.

The impact of oncogenic mutations of the viral Src kinase on the structure and stability of the SH3 domain

Acta Crystallographica Section D, Volume 77, Issue 6, Page 854-866, June 2021., 2021
The crystal structures of three viral Src kinase (v‐Src) SH3‐domain variants have been determined in order to obtain insights into the roles of these oncogenic mutations in the function of v‐Src.Src kinase belongs to the family of Src‐related nonreceptor tyrosine kinases.

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
