TL;DR: It is shown that there is no direct link between EELS and LDOS maps, and that EELS can even be blind to hot spots in the gap between coupled nanoparticles.
Abstract: We investigate electron-energy-loss spectroscopy (EELS) on metallic nanoparticles, through simulations, and provide a comprehensive comparison between EELS and the photonic local density of states (LDOS). Most importantly, we show that there is no direct link between EELS and LDOS maps, and that EELS can even be blind to hot spots in the gap between coupled nanoparticles. Although intimately related, the two quantities provide complementary information. This finding is in marked contrast to recently reported results.

TL;DR: In this paper, a distinction between the concepts of purchase affordability (whether a household is able to borrow enough funds to purchase a house) and repayment affordability (the burden imposed on a household of repaying the mortgage) is made, and a new methodology for constructing affordability measures that draws on the value-at-risk concept and takes account of the whole distribution of household income and house prices rather than just the median is presented.

TL;DR: In this paper, a planar optode imaging approach is presented to study the two-dimensional distribution and dynamics of a range of analytes using a color filter of standard commercial single lens reflex cameras to simultaneously record different colors of luminophore emission light using only one excitation light source.
Abstract: A simple, high resolution colormetric planar optode imaging approach is presented. The approach is simple and inexpensive yet versatile, and can be used to study the two-dimensional distribution and dynamics of a range of analytes. The imaging approach utilizes the inbuilt color filter of standard commercial digital single lens reflex cameras to simultaneously record different colors (red, green, and blue) of luminophore emission light using only one excitation light source. Using the ratio between the intensity of the different colors recorded in a single image analyte concentrations can be calculated. The robustness of the approach is documented by obtaining high resolution data of O2 and pH distributions in marine sediments using easy synthesizable sensors. The sensors rely on the platinum(II)octaethylporphyrin (PtOEP) and lipophilic 8-Hydroxy-1,3,6-pyrenetrisulfonic acid trisodium (HPTS) salt derivate for O2 and pH measurements, respectively. The brightness of both indicators is dramatically enhanced by making use of energy transfer from a donor molecule (Macrolex yellow coumarin). Furthermore, the emission from the donor serves as an internal reference for the O2 sensor. The approach relies on semitransparent sensors, facilitating visual inspection of the sediment behind the sensors during measurements. Software for data acquisition and calibration will be available from the authors, whereas all hardware is available from a range of commercial sources. The total cost of the complete measuring system is approximately $3000 US.

TL;DR: It is argued that the neurofilament light subunit can reflect acute axonal damage mediated by inflammatory mechanisms and can imply prognostic value for conversion from clinically isolated syndrome (CIS) to definite MS.
Abstract: Neurodegeneration is the correlate of disease progression in multiple sclerosis (MS) and thus biological biomarkers that sensitively reflect this process are much needed. Neurofilament protein subunits are potential cerebrospinal fluid (CSF) biomarkers for disease progression in MS. We argue that the neurofilament light subunit can reflect acute axonal damage mediated by inflammatory mechanisms and can imply prognostic value for conversion from clinically isolated syndrome (CIS) to definite MS. The neurofilament heavy subunit may rather reflect chronic irreversible damage and has prognostic value for disease progression or disability. The neurofilament intermediate subunit has not yet been studied. Recent studies showing higher neurofilament light or heavy subunit levels to be altered upon treatment regimes indicate their potential clinical value in monitoring treatment or side effects. Future studies should be aimed at the optimisation, standardisation and interlaboratory implementation of the assays and address the predictive value of these biomarkers.

TL;DR: Traditional oil refining processes examined the effect on the content of phorbol esters, a family of compounds known to cause a large number of biological effects such as tumor promotion and inflammation, found almost no effect could be observed with degumming and deodorization, whereas the steps of deacidification and bleaching could reduce the content.
