Downconversion Master Slave OCT With a Bidirectional Sweeping Laser

Journal of Biophotonics, EarlyView.
ABSTRACT This paper explores the challenges of signal processing when using optical coherence tomography (OCT) imaging instruments driven by asymmetric MHz bidirectional sweeping lasers. A downconversion master–slave (DMS) method is proposed as a viable alternative to the traditional OCT protocol.

Metasurfaces in Adaptive Optics: A New Opportunity in Optical Wavefront Sensing

Laser &Photonics Reviews, EarlyView.
Wavefront sensing constitutes a critical component of adaptive optics systems, aimed at quantitatively measuring distorted wavefronts and enabling closed‐loop correction in optical setups. Metasurfaces, as planar optical elements composed of nanoscale structures, provide exceptional freedom in modulating multiple dimensions of the light field.

Association of the long fluoroscopy time with factors in contemporary primary percutaneous coronary interventions.

PLoS ONE, 2020
BACKGROUND:Since the long fluoroscopy time in primary PCI for ST-segment elevation myocardial infarction (STEMI) could be an indicator of delayed reperfusion, it should be important to recognize which types of lesions require longer fluoroscopy-time in ...

Influence of Viscosity Ratio on the Mechanical, Morphological, and Rheological Properties of Thermoplastic Dynamic Vulcanizates from Devulcanized Tire Rubber and Polypropylene

Macromolecular Materials and Engineering, EarlyView.
This study explores how polypropylene viscosity influences the structure and performance of thermoplastic dynamic vulcanizates made with devulcanized tire rubber. Higher matrix viscosity results in better dispersion of the rubber phase, forming smaller domains and enhancing mechanical properties. The findings support more efficient recycling strategies

Chemical Ionization Mass Spectrometry: Fundamental Principles, Diverse Applications, and the Latest Technological Frontiers

Mass Spectrometry Reviews, EarlyView.
ABSTRACT The review examines the evolution of chemical ionization mass spectrometry (CI‐MS), a technique developed in 1966 by Field and Munson. CI is a soft‐ionization method that produces more intense molecular ions with less fragmentation than electron ionization (EI).

Mechanical chest-compression devices: current and future roles [PDF]

, 2010
Purpose of review: It is recognised that the quality of CPR is an important predictor of outcome from cardiac arrest yet studies consistently demonstrate that the quality of CPR performed in real life is frequently sub-optimal.

Robust Confidence Intervals for Process Capability Index Based on Cost and Loss Functions With Bootstrap Enhancement

Quality and Reliability Engineering International, EarlyView.
ABSTRACT Process capability indices (PCIs) are commonly used to evaluate a process's performance in relation to the standards. Greater PCIs do not necessarily translate into lower rejection rates, even though they do indicate a higher level of process quality. Thus, a loss‐ and cost‐based PCI is a better way to measure process capability.
