International audienceThe research findings provide evidence that time-oriented data visualizations can contribute to faster information processing, bet-ter understanding and improved recall. Thus, they are used in many application domains – medicine, law enforcement, traffic and navigation control to name but a few. Simultaneously, human's time perception varies depending inter alia on culture, language, personal experience and situational factors. Although, the differences caused by the aforemen-tioned aspects were acknowledged and addressed in the Human Com-puter Interaction (HCI) field for decades their impact on time-oriented data visualizations was largely neglected. To fill this gap, we investigate the influence of time spatializations (or-ganization of time along axes) on the response time and accuracy of inferences based on time-oriented data visualizations. Moreover, we ex-amine users' preferences toward different time arrangements. Our find-ings show that user-adapted organization of time along axes can speed up the decision-making process and increase the user experience

New measurement of double beta decays of Mo to excited states of Ru with the CUPID-Mo experiment
The CUPID-Mo experiment, located at Laboratoire Souterrain de Modane (France), was a demonstrator experiment for CUPID. It consisted of an array of 20 LiMoO (LMO) calorimeters each equipped with a Ge light detector (LD) for particle identification. In this work, we present the result of a search for two-neutrino and neutrinoless double beta decays of Mo to the first 0 and excited states of Ru using the full CUPID-Mo exposure (2.71 kgyr of LMO). We measure the half-life of decay to the state as . The bolometric technique enables measurement of the electron energies as well as the gamma rays from nuclear de-excitation and this allows us to set new limits on the two-neutrino decay to the state of T^{2\nu \rightarrow 2_1^+}_{1/2}>4.4\times 10^{21} \ \mathrm{yr} \ \text{(90 % c.i.)} and on the neutrinoless modes of T_{1/2}^{0\nu\rightarrow 2_1^+}>2.1\times10^{23} \ \mathrm{yr}\ \text{(90 % c.i.)}, T_{1/2}^{0\nu\rightarrow 0_1^+}>1.2\times10^{23} \ \mathrm{yr}\ \text{(90 % c.i.)}. Information on the electrons spectral shape is obtained which allows us to make the first comparison of the single state (SSD) and higher state (HSD) decay models for the excited state of Ru
Final results on the decay half-life limit of Mo from the CUPID-Mo experiment
The CUPID-Mo experiment to search for 0 decay in Mo has been recently completed after about 1.5 years of operation at Laboratoire Souterrain de Modane (France). It served as a demonstrator for CUPID, a next generation 0 decay experiment. CUPID-Mo was comprised of 20 enriched LiMoO scintillating calorimeters, each with a mass of 0.2 kg, operated at 20 mK. We present here the final analysis with the full exposure of CUPID-Mo (Mo exposure of 1.47 kgyr) used to search for lepton number violation via 0 decay. We report on various analysis improvements since the previous result on a subset of data, reprocessing all data with these new techniques. We observe zero events in the region of interest and set a new limit on the Mo 0 decay half-life of year (stat.+syst.) at 90% C.I. Under the light Majorana neutrino exchange mechanism this corresponds to an effective Majorana neutrino mass of \left < (0.28-- eV, dependent upon the nuclear matrix element utilized
The background model of the CUPID-Mo experiment
International audienceCUPID-Mo, located in the Laboratoire Souterrain de Modane (France), was a demonstrator for the next generation decay experiment, CUPID. It consisted of an array of 20 enriched LiMoO bolometers and 20 Ge light detectors and has demonstrated that the technology of scintillating bolometers with particle identification capabilities is mature. Furthermore, CUPID-Mo can inform and validate the background prediction for CUPID. In this paper, we present a detailed model of the CUPID-Mo backgrounds. This model is able to describe well the features of the experimental data and enables studies of the decay and other processes with high precision. We also measure the radio-purity of the LiMoO crystals which are found to be sufficient for the CUPID goals. Finally, we also obtain a background index in the region of interest of 3.7(stat)(syst)counts/E/mol/yr, the lowest in a bolometric decay experiment
