The Influence of Explosion Relief Vent Layouts on Explosion Overpressures in Large Biomass Storage Vessels

open access: yesChemical Engineering Transactions, 2016
International standards for dust explosion relief design (NFPA 68 2013, EN 14491 2012, VDI 3673) have largely been developed for conventional bulk material handling silos with volumes of less than 10,000 m3, with empirical calculations being used to ...

On optimization of pressure-relief parameters of water jet slots in deep rockburst coal seams

open access: yesYantu gongcheng xuebao, 2023
In order to determine the optimal parameters of pressure relief by high-pressure water jet slotting in deep rockburst coal seams, the principles of pressure relief and impact prevention are analyzed through numerical simulation and theoretical deduction.

Cell surface interactome analysis identifies TSPAN4 as a negative regulator of PD‐L1 in melanoma

open access: yesMolecular Oncology, EarlyView.
Using cell surface proximity biotinylation, we identified tetraspanin TSPAN4 within the PD‐L1 interactome of melanoma cells. TSPAN4 negatively regulates PD‐L1 expression and lateral mobility by limiting its interaction with CMTM6 and promoting PD‐L1 degradation.

Pressure Characteristics of Maxillary and Mandibular Edentulous Impressions: An In-vitro Study

open access: yesRUHS Journal of Health Sciences, 2023
Introduction: One major factor that determines the stability and retention of prosthesis is the amount of pressure produced during final impression. The aim of the present study was to assess the pressure changes created during impression process by ...

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

open access: yesMolecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Hot-spot congestion relief in public-area wireless networks [PDF]

open access: yesProceedings Fourth IEEE Workshop on Mobile Computing Systems and Applications, 2003
Wireless LAN administrators are often called upon to deal with the problem of sporadic user congestion at certain popular spaces ("hot-spots") within the network. To address this problem, we describe and evaluate two new approaches, explicit channel switching and network-directed roaming for providing hot-spot congestion relief while maintaining pre ...

Metformin promotes mitochondrial integrity through AMPK‐signaling in Leber's hereditary optic neuropathy

open access: yesFEBS Open Bio, EarlyView.
Metformin mediates mitochondrial quality control in Leber's hereditary optic neuropathy (LHON) fibroblasts carrying mtDNA mutations. At therapeutic levels, metformin activates AMPK signaling to restore mitochondrial dynamics by promoting fusion and restraining fission, while preserving mitochondrial mass, enhancing autophagy/mitophagy and biogenesis ...
