Pacemaker neurons exert control over neuronal circuit function by their intrinsic ability to generate rhythmic bursts of action potential. Recent work has identified rhythmic gut contractions in human, mice and hydra to be dependent on both neurons and the resident microbiota. However, little is known about the evolutionary origin of these neurons and their interaction with microbes. In this study, we identified and functionally characterized prototypical ANO/SCN/TRPM ion channel expressing pacemaker cells in the basal metazoan Hydra by using a combination of single-cell transcriptomics, immunochemistry, and functional experiments. Unexpectedly, these prototypical pacemaker neurons express a rich set of immune-related genes mediating their interaction with the microbial environment. Functional experiments validated a model of the evolutionary emergence of pacemaker cells as neurons using components of innate immunity to interact with the microbial environment and ion channels to generate rhythmic contractions.

In the current data article, we present detailed characteristics of voids in carbon/epoxy composite laminates as well as the original image stacks, obtained via X-ray micro-Computed Tomography (micro-CT) . Five different lay-ups are produced with altering the recommended cure cycle in order to intentionally induce voids in the material. For each lay-up, an image stack (consisting of tomographic slices) and a dataset are provided. The image slices are in 8-bit TIF format. The datasets (spreadsheets) include the volume, size parameters, shape parameters, orientation, and location of all the detected voids in the specimen. The segmentation of the images and quantification of voids are performed in VoxTex, an in-house software for processing of micro-CT results. The data is linked to a Data in Brief article "Mehdikhani et al., A dataset of voids’ characteristics in multidirectional carbon fiber/epoxy composite laminates, obtained using X-ray micro-computed tomography, DIB 27 (2019) 104686" and linked to the article "Mehdikhani et al. Detailed characterization of voids in multidirectional carbon fiber/epoxy composite laminates using X-ray micro-computed tomography. Comp Part A 125 (2019) 105532".

The dataset provides a chaos game representation (CGR) of SARS-CoV-2 virus nucleotide sequences. The dataset is composed of 100 virus instances of SARS-CoV-2. In addition, the dataset also provides a CGR representation of 11540 viruses from the Virus-Host DB dataset and the other three Riboviria viruses from NCBI.

The models of doing for school mathematics varies and mainly based on etymological sense of meaning according to words or phrases in a sentence. The students positioned their thinking based on word understanding of a proof problem. They also relate between presented information and formula in doing proof. When facing visual representations, the students tend to prove by algebra. The visual representations to be imagined merely as a tool for arranging a formal proof, i.e. when so many algebra symbols in proving, including formula and the procedures. For algebraic or analytic or symbolic-illustrative representation, the mathematics proof is just symbolic manipulation than the meaning. In doing proof, a meaning of word or the combination construct a pattern of proof changed to mathematics statement. For example, a word 'to test' has multi-example pattern. While, 'to judge' shows logical pattern. The etymological sense is a learning understanding of doing proof. There s an intersection of the etymological and the understanding. Data presented in Etymological-Understanding axis. The intersections moved from information (or data) toward pattern in proof problem. There are two other intersection, i.e. meaning and experience. That is an easy way to prove much of mathematics problems. When facing to the difficult proof problem, a set of the intersection have an action role in doing proof to an intervention of the etymological sense of meaning. That is a real learning activities, specifically in doing proof. . There is also an intersection of doing proof between word meaning and logic. That is a new culture in doing mathematics proof, a belief of the learning. The data embedded in a four quadrant of Monophonic-Context axis and Velocity-Viscosity axes (Fig. 2). The students' experience also appear in thinking, drawing (a step to a proof), testing, and developing their performances. The etymological sense of word or phrase meaning brings the students to a broader or more rational (not common sense) ways to prove. The proof trajectories growth cross mathematics content knowledge. That is psychological context addressed by students' belief and determined using the empirical proof. The fitted of the empirical data mapping its model as an entropy value indicated 'creative proof', i.e. in illustrating, describing mathematics representations, making a rational (or consistence) relation, and generating a proof. The models of proof show the differences representation. When the students ask to 'try', then they elaborate a proof by cases. . But, to 'determine' made more algebra thinking. Finally, there are performance levels in doing proof etymologically. Nine performances aroused as variables of etymological sense of meaning. That is a measure of teaching and learning of doing proof. That is an exploring of the etymological toward more proof representation. That is way to assess doing proof through meaning of word. .

This dataset contains records of an experimental research project on energetic expenditure during walking and carrying burdens in a sample of humans, of both sexes, aged from 23 to 50 years old. The dataset also contains some anthropometrical and body composition data of the subjects. Metabolic rates were also recorded during the different tests, performed at the BioEnergy and Motion Lab (LabBioEM) of National Research Center on Human Evolution (CENIEH, Spain) in 2015. Main outcomes and findings of the experimental project were published in several works (Prado-Nóvoa et al., 2019; Vidal-Cordasco et al., 2017; Zorrilla-Revilla et al., 2017). The list of references and the description of recorded variables are included in the data and document files.

There is a detailed Readme.pdf in the files for the informations about the dataset. The main purpose is providing a dataset for the vibration behavior of a robot manipulator system under the control input of model-associative vibration control (MAVC) prodecure. Velocity profile is shown as [∗,𝑡𝑐𝑜𝑛,𝑡𝑑𝑒𝑐,𝑡𝑚] in study. In the case studies for both simulations and experiments, the parameters are varied as follows; 𝑡𝑐𝑜𝑛 can be valued as 0, 𝑡1ℎ or 2𝑡1ℎ, 𝑡𝑑𝑒𝑐 can be valued as 𝑡1ℎ,2𝑡1ℎ,3𝑡1ℎ,4𝑡1ℎ or 5𝑡1ℎ and 𝑡𝑚 can be valued as 1 or 1.5 seconds for corresponded 90 or 135 angular displacements. Thus thirty different velocity profiles are produced with aim to performed on system. Cases are invastigated with and without performing the MAVC procedure. Than the robot manipulator is examined for both unloaded and loaded cases, therefore total one hundred twenty cases are occured. More details can be found in related study.
