Robustness Analysis of Air Route Network Based on Topology Potential and Relative Entropy Methods

open access: yesJournal of Advanced Transportation, Volume 2021, Issue 1, 2021., 2021
Air route network (ARN) is the important carrier of air transport, and its robustness has important influence on the safety and stability of air transport. To analyze the robustness of ARN, in this paper, a topology potential relative entropy (TPRE) model is proposed, based on topology potential (TP) and relative entropy (RE) methods. Firstly, the TPRE

Calcium inhibits promotion by hot dog of 1,2-dimethylhydrazine-induced mucin-depleted foci in rat colon. [PDF]

open access: yesInt J Cancer, 2013
Epidemiology suggests that processed meat is associated with colorectal cancer risk, but few experimental studies support this association. We have shown that a model of cured meat made in a pilot workshop promotes preneoplastic lesions, mucin-depleted ...

Extending the scope of coiled‐coil crystal structure solution by AMPLE through improved ab initio modelling

open access: yesActa Crystallographica Section D, Volume 76, Issue 3, Page 272-284, March 2020., 2020
The solution of coiled‐coil crystal structures may be achieved by AMPLE through the use of ensembled ab initio models in molecular replacement. Improvements in ab initio modelling of elongated helices and oligomeric coiled‐coils allow AMPLE to solve a greater number of coiled‐coil structures and at lower resolution than previously achieved.The phase ...

Human Health Risk Assessment of Heavy Metals in Groundwater in the Luan River Catchment within the North China Plain

open access: yesGeofluids, Volume 2020, Issue 1, 2020., 2020
The Luan River catchment within the North China plain has been famous for the development of its iron mineral resources since the 1950s. At the same time, it is also the main grain‐producing area, known as the granary of eastern Hebei Province. Groundwater plays an important role in this region, and thus, it is imperative for us to improve our ...

The effect of haem in red and processed meat on the endogenous formation of N-nitroso compounds in the upper gastrointestinal tract [PDF]

open access: yes, 2007
Red and processed meat consumption increases the risk of large bowel cancer and it has been demonstrated that haem in red meat stimulates the endogenous production of N-nitroso compounds (NOCs) within the human intestine.
