... This repository contains the FAST algorithm graphical user interface and some sample image used in the following work: - Salvi M., Cerrato V., Buffo A., and Molinari F., "Automated Segmentation of Brain Cells for Clonal Analyses in Fluorescence Microscopy Images", J Neurosci Methods 2019 (DOI: 10.1016/j.jneumeth.2019.108348) ABSTRACT The understanding of how cell diversity within and across distinct brain regions is ontogenetically achieved is a pivotal topic in neuroscience. Clonal analyses based on multicolor cell labeling represent a powerful tool to tackle this issue and disclose lineage relationships, but produce enormous sets of fluorescence images, leading to time consuming analyses that may be biased by the operator’s subjectivity. Thus, time-efficient automated software are needed to analyze images easily, accurately and without subjective bias. In this paper, we present a fully automated method, named FAST (‘Fluorescent cell Analysis Segmentation Tool’), for the segmentation of neural cells labeled by multicolor combinations of fluorophores and for their classification into clones. The proposed method was tested on 77 high-magnification fluorescence images of adult mouse cerebellar tissues acquired using a confocal microscope. Automatic results were compared with manual annotations and two open-source software designed for cell detection in microscopic imaging. The algorithm showed very good performance in the cellular detection and in the assignment of the clonal identity. To the best of our knowledge, FAST is the first fully automated technique for the analysis of cellular clones based on combinatorial expression of fluorescent proteins. The proposed approach allows to perform clonal analyses easily, accurately and objectively, overcoming those biases and errors that may result from manual annotations. Moreover, it can be broadly applied to the quantification and colocalization within cells of fluorescent markers, therefore representing a versatile and powerful tool for automated quantitative analyses in fluorescence microscopy.
Improve the interfacial adhesion, corrosion resistance and combustion properties of aluminum powder by modification of nickel and dopamine
Contributors: Li Liang, Xiaode Guo, Xin Liao, Zhipeng Chang
... To improve the interface incompatibility, poor corrosion resistance, and limited combustion efficiency of aluminum powder for propellant applications. The surface of the naked aluminum was coated with a layer of dense nickel of about 100 nm by replacement method. A polydopamine film was then deposited by self-polymerization. The double-layer structure and chemical composition were investigated. The polydopamine content of composite particles was 2.3% by thermal analysis. And its heat release around 1050 C reached 4137 J g-1, which was much higher than that of aluminum of 1644 J g-1. The surface energies was used to calculate the theoretical adhesion work of aluminum and composite particles to propellant binder. The adhesion work after modification was increased from 62.33 mN m-1 to 74.89 mN m-1. No matter in the weak acid/alkaline or neutral environment, the composite particles exhibited excellent stability at 50 C. In addition, the combustion test revealed that the composite particles had higher combustion efficiency, smaller condensed phase product size, and stronger ignition ability. All the conclusions indicate after modification by nickel and dopamine, the comprehensive performance of aluminum is improved, and it may be used as an energy component in propellants or other energetic fields.

Data for: Lean combustion analysis using a corona discharge igniter in an optical engine fueled with methane and a hydrogen-methane blend
Contributors: Valentino Cruccolini
... Since the amount of data that has been acquired, processed and presented in the paper is non-negligible, the Authors decided to share, as an example, only two combustion points data. Both these points are related to a lambda 1.4 air-CH4 mixture: one ignited by a conventional spark igniter, and one by an RF corona igniter. They have been acquired in the Internal Combustion Engine Lab of the University of Perugia, Department of Engineering. Authors agree to share further data upon request. ------------------------------------------------------------------------------------------------------- The shared data have been converted into an open-access format for sharing purposes: a .csv file for indicating analysis (only in-cylinder pressure is shown) and a .mp4 file (flame images). The .csv files contain the in-cylinder pressure traces in 103 columns: the first one is related to the crank angle degree value (one row each 0.1 CAD), the second one to the average pressure trace, and each of the following 101 is related to the in-cylinder pressure of a single combustion event. The .mp4 files contain the flame images related to one of the 101 combustion pressure traces reported in the corresponding .csv file. The temporal resolution is 0.3 CAD/frame, and the .mp4 speed, during the conversion, was set to 20 fps.

... Abolition of contractile activity in in vitro neuromuscular junctions within multi-nodal microfluidic chips using alpha-Bungarotoxin. Chips seeded as described above were allowed to mature for 21 days after seeding. Chips were selected for high contractile activity of myotubes that had visual contact with axons (more than 1 contraction per minute over 5 minutes with at least 1 contraction in each minute, the day prior to the experiment). Video of pre-experiment activity was recorded for 1 min followed by counting of the total number of contractions in 10 min. The cells were allowed to recover for 1 h at 37°C, 5% CO2 before addition of 1:100 of α-BTX at a final concentration of 1.25μM or of 0.75μl sterile PBS and incubation of 10 min at 37°C, 5% CO2. The α-BTX was only added to the central well containing the myotubes, which was fluidically isolated by hydrostatic pressure throughout the incubation. Another 1 min video of activity after intervention was recorded before counting the total number of contractions in 10 min. Cells were fixed immediately after the final count. For quantitative analysis the experiment was repeated with 10 min video being recorded as baseline followed by 1 h recovery at 37°C, 5% CO2 and treatment. Another 10 min video was recorded after treatment, and blinded quantification was carried out for both.

... A swirling fluidized bed reactor design for the preparation of supported nanoparticles is reported. It uses a DC plasma torch that decomposes and vaporizes salt precursors; the cationic part condenses as metal nanoparticles on a powder support. Any fluidizable granular material can be used as support, as long as it withstands the temperatures of the plasma torch. The torch is located at the center of the reactor axis and the powder is fluidized using a cyclonic action (swirl) to minimize the space where the grains could come into direct contact with the plasma zone. The reactor was tested for the production of silver nanoparticles (AgNPs) supported on silica-alumina, using silver nitrate as precursor.
