Real-time AI-assisted quality control during nasopharyngolaryngoscopy: a randomized controlled trial [PDF]

open access: yesnpj Digital Medicine
Nasopharyngolaryngoscopy (NPL) is widely used to examine the nasopharyngolaryngeal anatomical sites. The quality of NPL depends on the endoscopist’s performance, and incomplete examinations may contribute to missed findings in practice.

N-Acetylneuraminate Pyruvate Lyase Promotes Cell Adaptation to Glucose Deprivation by Regulating Intracellular ATP Levels [PDF]

open access: yesCurrent Issues in Molecular Biology
N-acetylneuraminate pyruvate lyase (NPL) is a key enzyme in sialic acid catabolism that links sialylation to cellular metabolism, but its role in cancer cell metabolic adaptation is poorly defined.

MetaLigand provides a prior-knowledge-guided framework for predicting non-peptide ligand mediated cell-cell communication [PDF]

open access: yesCell Reports: Methods
Summary: Non-peptide ligands (NPLs), including lipids, amino acids, carbohydrates, and non-peptide neurotransmitters and hormones, play a critical role in ligand-receptor-mediated cell-cell communication, driving diverse physiological and pathological ...

Remote Measurements of Industrial CO2 Emissions Using a Ground-Based Differential Absorption Lidar in the 2 µm Wavelength Region

open access: yesRemote Sensing, 2023
Carbon dioxide (CO2) is a known greenhouse gas and one of the largest contributors to global warming in the Earth’s atmosphere. The remote detection and measurement of CO2 from industrial emissions are not routinely carried out and are typically ...

Comparing ultrastable lasers at 7 × 10−17 fractional frequency instability through a 2220 km optical fibre network

open access: yesNature Communications, 2022
Precision measurement plays an important role in frequency metrology and optical communications. Here the authors compare two geographically separate ultrastable lasers at 7 × 10−17 fractional frequency instability over a 2220 km optical fibre link and ...

Towards an Ultra-High-Speed Combustion Pyrometer

open access: yesInternational Journal of Turbomachinery, Propulsion and Power, 2020
Measuring reliably the correct temperature of a sooty flame in an internal combustion engine is important to optimise its efficiency; however, conventional contact thermometers, such as thermocouples, are not adequate in this context, due to drift ...

Non-Performing Exposures delle banche: diktat impazienti e soluzioni nazionali vs gestione paziente e Asset Management Companies a livello europeo [PDF]

open access: yesRisk Management Magazine, 2020
In Europa e in Italia sono stati registrati significativi progressi dalle banche in materia di Non Performing Exposures (NPE: past due, unlikely to pay – UTP e non performing loans – NPL). Nell’Euroarea gli NPL hanno toccato il picco nel 2013 (in Italia

An integrated discrete event simulation and particle swarm optimisation model for optimising efficiency of cancer diagnosis pathways

open access: yesHealthcare Analytics, 2022
The National Health Service (NHS) constitution sets out minimum standards for rights of access of patients to NHS services. The ‘Faster Diagnosis Standard’ (FDS) states that 75% of patients should be told whether they have a diagnosis of cancer or not ...
