Comparing the paths of Hedgehog release in artificial and natural settings

open access: yesFEBS Letters, EarlyView.
Hh morphogens require solubilization factors to overcome their tight association with the plasma membrane and signal to distant cells, but the precise functions of these factors are controversial. Here, we use published in vivo observations as the most relevant evidence to test their suggested functions and discuss contradictions and gaps between in ...

Rock burst risk assessment of working face during open-off cut based on acoustic emission monitoring

open access: yesMeikuang Anquan, 2021
Impact risk assessment is a work that must be carried out in driving and stoping stage in mining coal seam with impact risk to ensure the safety of driving and stoping working face.

Testing and evaluating real driving emissions with PEMS

open access: yesCombustion Engines, 2018
Testing of real driving emissions (RDE) with portable emission measuring system (PEMS) in an appropriate road circuit became an obligatory element of new type approval of passenger cars since September 2017. In several projects the Laboratory for Exhaust Emissions Control (AFHB) of the Berne University of Applied Sciences (BFH) performed comparisons on

Assessment of real driving emissions via portable emission measurement system [PDF]

open access: yesIOP Conference Series: Materials Science and Engineering, 2017
The European Commission approved a so-called Real Driving Emission (RDE) test in response to the criticisms to the current driving cycle used at chassis dyno for homologation purpose (NEDC): it is considered outdated and misleading since air pollutants in real driving conditions are considerably higher than the certification thresholds.

Investigation on An Innovative Hydrocarbon Sensor for Real Drive Emissions

open access: yesJournal of Advanced Research in Fluid Mechanics and Thermal Sciences, 2021
European law specifies limit values (and test methods) for pollutant emissions from light duty vehicles and heavy-duty engines including carbon monoxide (CO), hydrocarbons (HC), nitrogen oxide (NOx) and particulates, which are considered dangerous to human health.

Intrapatient tumour heterogeneity and clonal evolution in an autopsy study of metastatic salivary gland cancer

open access: yesMolecular Oncology, EarlyView.
Tumour heterogeneity and clonal evolution of metastatic salivary gland cancer were evaluated in two patients with adenoid carcinoma and one patient with myoepithelial carcinoma. Radiology‐guided autopsy enabled multi‐region sampling (total samples n = 149), followed by whole‐genome sequencing and phylogenetic reconstruction (17 tumour samples, 4–7 per ...

Variations in carbon emissions from vehicles at signalised intersections

open access: yes, 2011
Carbon emissions from road transport make up 20% of the total greenhouse gas emissions in the UK. Therefore, reducing carbon emissions from road transport is significant in reaching carbon reduction targets.

Development of a Real-World Eco-Driving Cycle for Motorcycles

open access: yes, 2022
Climate change is a major issue all around the world. The transportation industry currently accounts for most CO2 emissions. The goal of this research is to develop a real-world eco-driving cycle for internal combustion engine motorcycles that can reduce

Regulation of the lncRNA NEAT1 by p53‐ΔNp63 crosstalk modulates the DNA damage response and therapeutic efficacy in HNSCC

open access: yesMolecular Oncology, EarlyView.
In head and neck squamous cell carcinoma (HNSCC) p53 and p63 exert opposite roles on the transcription regulation of the lncRNA NEAT1. Under basal conditions, p53 levels are low and p63 represses NEAT1 expression. Upon genotoxic stress, p53 is rapidly induced, displacing p63 from the NEAT1 promoter leading to NEAT1 transcriptional activation and ...

Real driving cycles and emissions for urban freight transport

open access: yesFrontiers in Big Data
This paper aims to evaluate the driving style effects, through the construction of driving cycles, on the polluting gases, in the context of urban freight transportation. For this, the method used was the construction of cycles through the Vehicle Specific Power (VSP) parameter, which considers instantaneous vehicle and road parameters better to ...
