Data about upper limb kinematics to test the efficacy of Action Observation Treatment
<p>The dataset contains the upper-limb kinematics collected in 40 participants before and after a short-term immobilization of the right arm. Three reach-to-grasp movements were required, targeting an object placed a) frontally at the level of the shoulders (A_low), b) frontally above the head (A_high), or c) laterally at the level of the shoulders (L_low). These movements were intended to test different degrees of freedom of the shoulder joint.</p> <p>Half of the participants underwent a virtual-reality action observation treatment (see Rizzolatti et al, Neuroscience and Biobehabioral Reviews, 2021), while the control group underwent a non-motor VR stimulation.</p>

Interferometric Observations of Water Fountain Candidates
<p>Located between the AGB and PN phases of low- and intermediate-mass stars, “Water Fountains” (WFs) may provide significant clues on the shaping process of PNe. For example, WFs are considered the first manifestation of collimated mass-loss in evolved stars, given their high-velocity H2O masers. There are 15 WFs known up to date, and several others are considered candidates. They are identified by H2O maser emission with a velocity spread broader than that of the OH maser emission (typically between 10-30 km/s), the latter indicating the expansion velocity of the circumstellar envelopes of AGB stars. We aim to ascertain the WF nature of these candidates and investigate the spatial distribution of their H2O masers through interferometric observations. An increase in the number of WFs will help us to study and constrain their properties as a group.</p>

Vesicles clustering around Wdr35-/- cilia lack electron dense decorations although electron-dense clathrin coated vesicles are still observed budding from the mutant plasma membrane (Figure 7- source data 1)
<p>Intraflagellar transport (IFT) is a highly conserved mechanism for motor-driven transport of cargo within cilia, but how this cargo is selectively transported to cilia is unclear. WDR35/IFT121 is a component of the IFT-A complex best known for its role in ciliary retrograde transport. In the absence of WDR35, small mutant cilia form but fail to enrich in diverse classes of ciliary membrane proteins. In <i>Wdr35 </i>mouse mutants, the non-core IFT-A components are degraded and core components accumulate at the ciliary base. We reveal deep sequence homology of WDR35 and other IFT-A subunits to α and ß' COPI coatomer subunits, and demonstrate an accumulation of 'coat-less' vesicles which fail to fuse with <i>Wdr35 </i>mutant cilia. We determine that recombinant non-core IFT-As can bind directly to<u> </u>lipids and provide the first <i>in-situ</i> evidence of a novel coat function for WDR35, likely with other IFT-A proteins, in delivering ciliary membrane cargo necessary for cilia elongation.</p>

Pulsation-driven mass loss observed in action from ground and space
<p>It is believed that pulsation plays a substantial role in the mass loss mechanism operating in Be stars, acting on top of rotation to lift material off the photosphere to feed the circumstellar disks. The causal relation between the combination of different non-radial pulsation modes and mass ejection is already well established. The next step forward will be given when the ejecta, which are the building blocks of the disks, are studied to determine their mass and angular content. To address this question, one must combine observations that probe the photospheric changes (photometry and spectroscopy of photospheric lines) with observations that track the ejecta proper (spectroscopy of emission lines). We are analyzing TESS data for what is by far the largest sample of Be stars observed from space to study their pulsational properties and circumstellar variability. This effort is aided by years of ground-based photometry, archival spectroscopy, and, most importantly, a campaign that is acquiring time-series Echelle spectra simultaneous with TESS observations. With the contemporaneous spectra, we are measuring changes in the photosphere and the evolution of the circumstellar environment at the same time, and establishing links between stellar and circumstellar variability. We find dramatic changes in the spectral features that probe the very inner regions of the disk on timescales of hours and days, which are correlated with signals seen by TESS when stars are actively ejecting material. Studying the star-disk interface in this way is of fundamental importance in understanding the elusive mass ejection mechanism of Be stars.</p>

PENELLOPE - UVES spectra of targets in the Lupus and Chamaeleon regions observed in 2021
<p>Spectra of the targets in the Chamaeleon I and Lupus regions observed with the VLT/UVES spectrograph in June-July 2021. These spectra are part of the PENELLOPE Large Program and are obtained close in time to the HST/ULLYSES spectra of the same targets. </p> <p>Here one can find the 1D flux-calibrated and telluric corrected spectra. Each object is observed simultaneously in three arms, blue, redu, redl, and the spectrum of each arm is saved in one file. The units of the spectra are: Flux [10**-16 erg/s/cm2/AA]; Wavelength [AA]. Each object is typically observed 3 times, the spectra are thus labelled as ep1, ep2, ep3.</p> <p>Data are public, we ask to ask to the authors of this release, who contributed to the observation preparation and data reduction, whether they want to be included in any publication using these data. The data reduction procedure is presented in Manara et al. (2021). Please quote this paper in any related publication. Please contact Carlo Manara for estimates of the stellar and accretion properties of these targets based on the corresponding X-Shooter data, and Antonio Frasca for stellar properties based on this data. </p> <p>For questions or comments please contact Carlo Manara, cmanara@eso.org</p>
