Transcriptional network analysis of PTEN‐protein‐deficient prostate tumors reveals robust stromal reprogramming and signs of senescent paracrine communication

Molecular Oncology, EarlyView.
Combining PTEN protein assessment and transcriptomic profiling of prostate tumors, we uncovered a network enriched in senescence and extracellular matrix (ECM) programs associated with PTEN loss and conserved in a mouse model. We show that PTEN‐deficient cells trigger paracrine remodeling of the surrounding stroma and this information could help ...

Experimental study on enhancing the foam spray range of compressed air foam nozzle

Journal of Safety Science and Resilience
As the core equipment in power systems, ultra-high voltage (UHV) transformers pose a high fire risk. The compressed-air foam spray nozzle is a novel end-release device that, due to its high efficiency and excellent suppression effect on oil-based fires ...

Power system monitoring and source control of the Space Station Freedom DC power system testbed [PDF]

Unlike a terrestrial electric utility which can purchase power from a neighboring utility, the Space Station Freedom (SSF) has strictly limited energy resources; as a result, source control, system monitoring, system protection, and load management are ...

UPS system: How can future technology and topology improve the energy efficiency in data centers? [PDF]

, 2014
A Data Center can consist of a large group of networked servers and associated power distribution, networking, and cooling equipment. All these applications consume enormous amounts of energy which result in a significant increase in energy inefficiency ...

Identification of serum protein biomarkers for pre‐cancerous lesions associated with pancreatic ductal adenocarcinoma

Molecular Oncology, EarlyView.
This work identified serum proteins associated with pancreatic epithelial neoplasms (PanINs) and early‐stage PDAC. Proteomics screens assessed genetically engineered mice with abundant PanINs, KPC mice (Lox‐STOP‐Lox‐KrasG12D/+ Lox‐STOP‐Lox‐Trp53R172H/+ Pdx1‐Cre) before PDAC development and also early‐stage PDAC patients (n = 31), compared to benign ...

Effect of oil immersion on the horizontal flame spread over transformer insulating paperboard with different sizes

Case Studies in Thermal Engineering
Transformer oil and insulating paperboard are widely used in oil-immersed transformers and may be ignited in the event of device failure. The present study aims to investigate the effect of oil immersion on the horizontal flame spread over the ...

Analysis of Distribution Network Protection Based on Distributed Power Sources

IOP Conference Series: Materials Science and Engineering, 2018
After a distributed power supply is connected to a distribution network, the distribution network changes from a single-supply radiant network to a network. When a fault occurs in the distribution network, the size and direction of the short - circuit current will change, giving rise to conventional relay protection. Normal operation brings a series of

Network divergence analysis identifies adaptive gene modules and two orthogonal vulnerability axes in pancreatic cancer

Molecular Oncology, EarlyView.
Tumors contain diverse cellular states whose behavior is shaped by context‐dependent gene coordination. By comparing gene–gene relationships across biological contexts, we identify adaptive transcriptional modules that reorganize into distinct vulnerability axes.
