Multicolored aurora in Iceland, by Marco Migliardi on behalf of Associazione Astronomica Cortina, Italy
<p>First place in the 2021 IAU OAE Astrophotography Contest, category Aurorae (still images)</p> <p>Aurorae are the result of ionisation and excitation processes in Earth's upper atmosphere, caused by charged particles from the solar wind or from coronal mass ejections. The different colours in an aurora display indicate the species of atmospheric atoms and molecules involved. The most common colour is a bright green, which, together with deep red, originates from atomic oxygen. Blue, purple and pink hues are much rarer and originate from molecular nitrogen. The reflection of the aurora in the water indicates the brightness of intense aurorae at higher latitudes.</p> <p>Credit: Marco Migliardi on behalf of Associazione Astronomica Cortina/IAU OAE.</p>
Dataset - Experimental study of frost detectability on planetary surfaces using multicolor photometry and polarimetry
<p>This dataset contains the polarimetric measurements performed for the paper "Experimental study of frost detectability on planetary surfaces using multicolor photometry and polarimetry" (Spadaccia et al., 2023 published on Icarus). The experimental work is aimed at measuring the changes of polarimetric and photomatric signal of a regolith when frost is deposited on top, at different temperatures and different wavelengths (450, 550, 750 nm).<br> <br> The .txt files are divided on regolith simulant (CR or MGS-1) and polarimetric phase angle (5 or 16°). The reflectance is measured at phase angle 50 or 61°. Each .txt file contains the averaged information of 5 experiments for CR at temperature T=-150°C, three experiments for MGS-1 at T=-130°C ("cold") and three experiments with MGS-1 at T=-120°C. </p> <p>The columns in the .txt files contain information on:</p> <p>#time[s] #temperatures[°C] #stdv_temperatures[°C] #Qblue #stdvQblue #Rblue #stdvRblue #Qgreen #stdvQgreen #Rgreen #stdvRgreen #Qred #stdvQred #Rred #stdvRred</p> <p>Where "Q" is the measurement of Q/I, "stdv" means standard deviation of the different experiments, "R" is the reflectance measured with the monochromatic camera, "blue", "green" and "red" are the three wavelengths of the incident light (450, 550, 750 nm). </p>

Images of apples for the use of the Viola-Jones method. Data set no. 1 - multicolor.
<p>The database contains pictures of apples made at different angles, from different sides and containing different varieties. In this way, two bases of apple images were created (each database contains over 1,100 images). This set is data set no. 1 - multicolor: processed images in multicolor. The photos were prepared for the best possible detection process in the Viola-Jones method. These photo bases with apples can be used to teach machines to recognize specific varieties and count apples.</p> <p>Please note that these are not raw data, but images processed for use in the algorithm in the Viola-Jones method.</p> <p> </p>
Chromophore carbonyl twisting in fluorescent biosensors encodes direct readout of protein conformations with multicolor switching
<p>Fluorescent labeling of proteins is a powerful tool for probing structure-function relationships with many biosensing applications. Structure-based rules for systematically designing fluorescent biosensors require understanding ligand-mediated fluorescent response mechanisms which can be challenging to establish. We installed thiol-reactive derivatives of the naphthalene-based fluorophore Prodan into bacterial periplasmic glucose-binding proteins. Glucose binding elicited paired color exchanges in the excited and ground states of these conjugates. X-ray structures and mutagenesis studies established that glucose-mediated color switching arises from steric interactions that couple protein conformational changes to twisting of the Prodan carbonyl relative to its naphthalene plane. Mutations of residues contacting the carbonyl can optimize color switching by altering fluorophore conformational equilibria in the apo and glucose-bound proteins. A commonly accepted view is that Prodan derivatives report on protein conformations via solvatochromic effects due to changes in the dielectric of their local environment. Here we show that instead Prodan carbonyl twisting controls color switching. These insights enable structure-based biosensor design by coupling ligand-mediated protein conformational changes to internal chromophore twists through specific steric interactions between fluorophore and protein.</p>
