Microplastic pollution research has suffered from inadequate data and tools for spectral (Raman infrared) classification. Spectral matching often are not accurate microplastics identification cost-prohibitive. Lack of accuracy stems the diversity microplastic pollutants, which represented in libraries. Here, we propose a viable software solution: Open Specy. Specy is on web (www.openspecy.org) an R package. free allows users to view, process, identify, share their spectra community library....
The ubiquitous pollution of the environment with microplastics, a diverse suite contaminants, is growing concern for science and currently receives considerable public, political, academic attention. potential impact microplastics in has prompted great deal research recent years. Many methods have been developed to answer different questions about microplastic pollution, from sources, transport, fate environment, effects on humans wildlife. These are often insufficiently described, making...
This report is the second part of a comprehensive two-part series aimed at reviewing an extensive and diverse toolkit novel methods to explore brain health function. While first focused on neurophotonic tools mostly applicable animal studies, here, we highlight optical spectroscopy imaging relevant noninvasive human studies. We outline current state-of-the-art technologies software advances, most recent impact these neuroscience clinical applications, identify areas where innovation needed,...
Neonatal congenital heart disease (CHD) is associated with altered cerebral hemodynamics and increased risk of brain injury. Two novel noninvasive techniques, magnetic resonance imaging (MRI) diffuse optical correlation spectroscopies (diffuse spectroscopy (DOS), (DCS)), were employed to quantify blood flow ( CBF) oxygen metabolism CMRO 2 ) 32 anesthetized CHD neonates at rest during hypercapnia. Cerebral venous saturation S v O CBF measured simultaneously MRI in the superior sagittal sinus,...
Life for many of the world's marine fish begins at ocean surface. Ocean conditions dictate food availability and govern survivorship, yet little is known about habitat preferences larval during this highly vulnerable life-history stage. Here we show that surface slicks, a ubiquitous coastal convergence feature, are important nurseries from habitats ecosystem scales. Slicks had higher densities phytoplankton (1.7-fold), zooplankton (larval prey; 3.7-fold), (8.1-fold) than nearby ambient...
Polymeric differences of plastic debris were assessed across four compartments the Main Hawaiian Islands (sea surface, windward beaches, leeward and seafloor) to better describe sources fate. Plastic pieces (n = 4671) collected from 11 three sea surface tows, seafloor dives. Fourier transform infrared spectroscopy identified polymers 3551 pieces. Significant (p < 0.05) in concentration, types, polymer composition, weathering found among compartments. Windward beaches had 1-2 orders magnitude...
Diffuse correlation spectroscopy (DCS) is a novel optical technique that appears to be an excellent tool for assessing cerebral blood flow in continuous and non-invasive manner at the bedside. We present new clinical validation of DCS methodology by demonstrating strong agreement between indices relative based on phase-encoded velocity mapping magnetic resonance imaging (VENC MRI) jugular veins superior vena cava. Data were acquired from 46 children with single ventricle cardiac lesions...
Pelagic Pacific sea turtles eat relatively large quantities of plastic (median 5 g in gut). Using Fourier transform infrared spectroscopy, we identified the polymers ingested by 37 olive ridley, 9 green, and 4 loggerhead caught as bycatch Hawaii- American Samoa-based longline fisheries. Unidentifiable samples were analyzed using high-temperature size exclusion chromatography with multiple detectors and/or X-ray photoelectron spectroscopy. Regardless species differences dive depths foraging...
We study aging in a colloidal suspension consisting of micron-sized particles liquid. This system is made glassy by increasing the particle concentration. observe samples composed two sizes, with size ratio 1:2.1 and volume fraction 1:6, using fast laser scanning confocal microscopy. technique yields real-time, three-dimensional movies deep inside glass. Specifically, we look at how size, motion, structural organization relate to overall Particles move spatially heterogeneous cooperative...
