Turn-key module for neutron scattering with sub-micro-eV resolution [PDF]

open access: yes, 2011
We report the development of a compact turn-key module that boosts the resolution in quasi-elastic neutron scattering by several orders of magnitude down to the low sub-micro-eV range.

Pre‐analytical optimization of cell‐free DNA and extracellular vesicle‐derived DNA for mutation detection in liquid biopsies

open access: yesMolecular Oncology, EarlyView.
Pre‐analytical handling critically determines liquid biopsy performance. This study defines practical best‐practice conditions for cell‐free DNA (cfDNA) and extracellular vesicle–derived DNA (evDNA), showing how processing time, storage conditions, tube type, and plasma input volume affect DNA integrity and mutation detection.

Development of Model ZJ40DBT Desert Fast Moving Trailer Rig

open access: yesShiyou jixie, 2017
At present, the dual-section telescopic structure is widely used in the trailer rig. Due to the low height of the derrick limited by the transportation, the majority of the products are only suitable for 19 m stand operation and do not meet the ...

Power-Efficient Modulation Schemes [PDF]

open access: yes, 2011
Coherent optical fiber communications had a brief period of popularity in the early 1990s, mainly because the optical links of that day were significantly power limited. Coherent detection provided a possibility of optically amplifying the signal to a power level that, after photodetection, made the thermal noise negligible. Two things, however, caused

Interrogating the immune landscape of microsatellite stable RAS‐mutated colon cancer

open access: yesMolecular Oncology, EarlyView.
COLOSSUS project RAS‐mutated MSS colon cancer study explored transcriptomics and immune cell density by immunohistochemistry (IHC), Immunoscore (IS), ISIC/TuLIS scores, mutation counts, and detected different prevalences but similar microenvironment composition across immune markers with clinical relevance for future immunotherapy combination ...

CCDC80 suppresses high‐grade serous ovarian cancer migration via negative regulation of B7‐H3

open access: yesMolecular Oncology, EarlyView.
PAX8 is a lineage‐specific master regulator of transcription in high‐grade serous ovarian cancer (HGSC) progression. We show for the first time that PAX8 facilitates proliferation and metastasis by repressing the cell autonomous tumor suppressor CCDC80 and inducing B7‐H3 expression.

Design of Dual-channel IGBT Driver Power Based on Voltage Negative Feedback Control

open access: yesKongzhi Yu Xinxi Jishu, 2013
A dual-channel IGBT drive power based on voltage negative feedback control is presented. This power circuit provides dualchannel output, 15 V and -10 V, which are used to turn on and turn off the IGBT.
