Ultralight vector dark matter search using data from the KAGRA O3GK run

Among the various candidates for dark matter (DM), ultralight vector DM can be probed by laser interferometric gravitational wave detectors through the measurement of oscillating length changes in the arm cavities. In this context, KAGRA has a unique feature due to differing compositions of its mirrors, enhancing the signal of vector DM in the length change in the auxiliary channels. Here we present the result of a search for U(1)B−L gauge boson DM using the KAGRA data from auxiliary length channels during the first joint observation run together with GEO600. By applying our search pipeline, which takes into account the stochastic nature of ultralight DM, upper bounds on the coupling strength between the U(1)B−L gauge boson and ordinary matter are obtained for a range of DM masses. While our constraints are less stringent than those derived from previous experiments, this study demonstrates the applicability of our method to the lower-mass vector DM search, which is made difficult in this measurement by the short observation time compared to the auto-correlation time scale of DM

Eye-tracking assistive technology: Is this effective for the developmental age? Evaluation of eye-tracking systems for children and adolescents with cerebral palsy

Objective. The main purpose of this study is to better understand whether eye-tracking technologies might be considered as a valid tool for enhancing communication and facilitating the process of rehabilitation, in order to improve the empowerment of persons in developmental age. Main content. The differences between the performance of subjects with cerebral palsy or similar movement disorders and the performance of subjects without disabilities while executing an eye pointing task has been analysed. Results. show that the performance of users with cerebral palsy had a significant difference in terms of efficiency compared to those without diagnosed body impairments, which showed both lower completion times and no errors during the entire test session. Conclusions. We argue that the issues emerged during the interaction should lead future studies to focus on the analysis of the usability of these systems with respect to users with neurological diseases in developmental age. © 2011 The authors and IOS Press.

Magnetic iron species highly dispersed over silica: use as catalysts for removal of pollutants in water

Fe2O3-SiO2 composites were prepared by impregnation (sample FeIMP) or doping (sample FeDOP) in the structure of porous silica. The dye removal capacity of the materials was investigated through adsorption and oxidation studies of methylene blue and rhodamine B. N2 adsorption/desorption measurements on FeIMP and FeDOP resulted in specific areas of 27 and 235 m2 g−1, respectively. Mössbauer spectroscopy and XRD data detected hematite and maghemite as the iron phases in the samples FeIMP and FeDOP, respectively. Adsorption isotherms and kinetic studies of the dyes were better fitted in DKR model for FeDOP, where the process follows a pseudo-second order with the interparticle diffusion step being the rate-limiting step. On the other hand, FeIMP has better fit in the Langmuir model. Photocatalytic activity was observed in FeDOP under UV irradiation by the presence of reaction-hydroxylated intermediates for MB (m/z = 301) and RhB (m/z = 459). However, the photocatalytic activity was strongly influenced by the adsorption affinity between dye/catalyst. Photogenerated holes are the species responsible for the dye degradation when the adsorption is too strong, while hydroxyl radical action will be favored when the adsorption is not vigorous as detected by ESI-MS.Fil: Freitas, Victor A.
