... For all fishes, hatching is a short but crucial event and the conditions under which it occurs considerably influence the success of the larvae. For coral reef fish, hatching is even more important because it marks the beginning of the dispersal phase. The timing of hatching dictates the conditions that the larvae will encounter, potentially influencing their survival and dispersal. Despite this importance, very few studies looked at hatching of marine fishes in the natural environment because of important technical constrains. In this study we directly examined the temporal pattern of hatching during the night. Using remote night vision cameras and infrared lights to avoid disturbances, we successfully document in situ hatching events of three coral reef fish species, all benthic brooders (Abudefduf saxatilis, Stegastes partitus, and Elacatinus lori). Hatching timing, rate and duration were computed from the observations and highlight different hatching strategies used by the fish species. The analysis of the fish behaviors shows that the males display parental cares beyond the incubation period of the eggs and increase activity during the hatching events. With this study, we can relate the hatching events to the environmental context, giving us a better understanding of the factors influencing the beginning of the larval phase. These observations highlight the benefit of in situ studies to better understand the characteristics and potential consequences of hatching. This dataset contains video examples of the hatching events for the three species and the data extracted from the videos for the analysis of the hatching rates and the paternal care behaviors.

... Study aim: to test reliability and sensitivity of the CALM scale for evaluation of responses to large body balance perturbations in the mediolateral direction. Design: analysis was conducted on data from 46 healthy university students of both genders. Task The task aim was to recover the body balance after unpredictable perturbations, trying to maintain the initial Romberg posture. Perturbations were applied through varying displacements of the support base on a custom made moveable platform. Support base displacements were made in the mediolateral direction, in three modalities: rotation, translation and the combined translation-rotation. Displacements were made in both directions in three speeds (20, 30 and 40º (cm)/s). Combination of modality, direction and perturbation velocity factors resulted in 18 distinct perturbations, making each perturbation unique in the protocol. The sequence of perturbations was pseudorandomized among all possibilities of variation of postural perturbation. Statistical analysis Reliability: Intra and inter-rater analyzes were performed by means of Cohen’s kappa. CALM scale scores and corresponding kinematic data were correlated by the Spearman's correlation. Analysis was performed through pairwise comparisons, using the Mann-Whitney U test for group-related comparisons in each perturbation mode by velocity, and the Wilcoxon matched pairs test for effects of perturbation mode (rotation X translation X combined; three velocities averaged), and velocity (low X high; separately for each perturbation mode). Statistically significant effects are reported only. Highlights Scale for evaluation of compensatory arm and leg movements to balance perturbation Large magnitude unpredictable balance perturbations in the mediolateral direction Patterns of compensatory movements are rated as a function of their stability High reliability and sensitivity to perturbation magnitude and training Instrument potentially able to predict probability of falls in at-risk individuals

... This dataset contains unprocessed data of two different setups of multi-stable VEH. The HG-C1400 (Panasonic Inc.) laser displacement meter was used to detect the displacement of the suspended magnet, and the tripod was used to fix the laser sensor. The laser sensor is powered by a DC-DC power supply. The quad-stable VEH was attached to a vibrating table, preferably horizontally settled to eliminate the effects of gravity. Sinusoidal excitation and frequency sweep tests (From 5Hz to 20Hz) were performed. The vibration test standard refers to IEC60068-2-6.

... Contains data and software from the publication: "Presynaptic Mitochondria Volumes and Complexity of Subsynaptic Distribution Increase During Development at a High-fidelity Synapse" currently under review. The preprint to this data set has been published on bioRxiv (https://doi.org/10.1101/689653). In this study, we created a helper-dependent adenoviral vector (HdAd) to co-express cytoplasmic EGFP and a genetically encoded peroxidase marker (mito-APEX2) at the calyx of Held, an excellent model for deciphering regulatory mechanisms of presynaptic function. ABSTRACT: The calyx of Held, a large glutamatergic presynaptic terminal in the auditory brainstem undergoes developmental changes to support the high action-potential firing rates required for auditory information encoding. In addition, calyx terminals are morphologically diverse which impacts vesicle release properties and synaptic plasticity. Mitochondria influence synaptic plasticity through calcium buffering and are crucial for providing the energy required for synaptic transmission. Therefore, it has been postulated that mitochondrial levels increase during development and contribute to the morphological-functional diversity in the mature calyx. However, the developmental profile of mitochondrial volumes and subsynaptic distribution at the calyx of Held remains unclear. To provide insight on this, we developed a helper-dependent adenoviral vector (HdAd) that expresses the genetically encoded peroxidase marker for mitochondria, mito-APEX, at the mouse calyx of Held. We developed protocols to detect labeled mitochondria for use serial block face SEM (SBF-SEM) to carry out semi-automated segmentation of mitochondria, high-throughput whole terminal reconstruction and presynaptic ultrastructure in mice of either sex. Subsequently, we measured mitochondrial volumes and subsynaptic distributions at the immature postnatal day 7 (P7) and the mature (P21) calyx. We found an increase of mitochondria volumes in terminals and axons from P7 to P21 but did not observe differences between stalk and swelling subcompartments in the mature calyx. Based on these findings, we propose that mitochondrial volumes developmentally increase to support high firing rates but have limited contribution to morphological-functional diversity at the calyx. Data are sorted by the figures they appear in. Media (movies and 3D models) and custom-written software are located in separate folders.

... The experimental data of crushing test in miniature web girder is here presented. This experimental data includes the force displacement data, video and setup images. The web girder was made by additive manufacturing in stainless steel 316L. The experimental test is a reproduction in reduced scale of an large-scale crushing test of a web girder structure made by ASIS in the nineties. The force displacement of the large-scale reference test was also included. True strain-stress curves obtained from tensile tests in additively manufactured samples are also included.
