Abstract

The search for particle-like dark matter with meV-to-GeV masses has developed rapidly in the past few years. We summarize the science case for these searches, the recent progress, and the exciting upcoming opportunities. Funding for Research and Development and a portfolio of small dark matter projects will allow the community to capitalize on the substantial recent advances in theory and experiment and probe vast regions of unexplored dark-matter parameter space in the coming decade., Comment: Contribution to Snowmass 2021. v2: includes endorsers and minor changes

Abstract

In this work, we combine Density Functional Theory data with a Thermodynamic and a kinetic model to determine the total concentration of hydrogen implanted in the sub-surface of tungsten exposed to a hydrogen flux. The sub-surface hydrogen concentration is calculated given a flux of hydrogen, a temperature of implantation, and the energy of the incoming hydrogen ions as independent variables. This global model is built step by step; an equilibrium between atomic hydrogen within bulk tungsten and a molecular hydrogen gas phase is first considered, and the calculated solubility is compared with experimental results. Subsequently, a kinetic model is used to determine the chemical potential for hydrogen in the sub-surface of tungsten. Combining both these models, two regimes are established in which hydrogen is preferentially trapped at either interstitial sites or in vacancies. We deduce from our model that the existence of these two regimes is driven by the temperature of the implanted tungsten sample; above a threshold or transition temperature is the interstitial regime, below is the vacancy regime in which super-saturated layers form within tenths of angstrom below the surface. A simple analytical expression is derived for the coexistence of the two regimes depending on the implantation temperature, the incident energy and the flux of the hydrogen ions which we use to plot the corresponding phase diagram.

31. Concepciones sobre el futuro y su enseñanza en maestros en formación inicial. Un estudio comparativo entre España e Italia

Author

Pérez-Rodríguez, N, De Alba-Fernández, N, Navarro-Medina, Zecca, L, Pérez-Rodríguez, N., De Alba-Fernández, N., Zecca, L., Pérez-Rodríguez, N, De Alba-Fernández, N, Navarro-Medina, Zecca, L, Pérez-Rodríguez, N., De Alba-Fernández, N., and Zecca, L.

Abstract

Research is presented which focuses on the conceptions of pre-service teachers about the future and its teaching. A review is made of some of the most interesting contributions in this field at international level. The study sample is composed of 114 students from two universities, one in Italy and one in Spain. Their answers to open-ended questions in a questionnaire are analysedqualitatively based on a system of categories. The results show broad agreement with the literature on this issue, although they introduce several nuances and show slight differences between the two countries. In conclusion, based on the results, some training strategies are proposed that could have an impact on the improvement of initial teacher training in this area.

Consecutive patients with early-to-moderate open-angle glaucoma (OAG) or ocular hypertension, who underwent XEN45 surgery, either alone or combined with phacoemulsification, and had at least a valid 12-month post-operative visit, were included in the study. Primary needling was performed by using a 30-gauge needle without viscoelastic. Subjects were divided in two groups: Eyes who underwent XEN+primary-needling (needling) and those who underwent XEN without primary-needling (no-needling). The primary end-point was the mean change in IOP from baseline to the last follow-up visit.Results: Sixty-three eyes, 19 (30.2%) in the needling group and 44 (69.8%) in the no-needling one, were included in the study. There were not significant differences in mean IOP lowering between needling and no-needling groups at month-12 (mean difference − 2.5± 5.3 mm Hg, p=0.0926). No significant differences in mean reduction of ocular-hypotensive medications were observed between needling and no-needling groups, p=0.8690. At month-12, 50 (80.6%) had blebs considered as functioning, with no difference between groups, p = 0.5631. At month-12, 59 (93.7%) eyes were classified as success, with no significant differences between needling (17/19) and no-needling (42/44) groups, p=0.3754. Secondary needling was performed in 8 (12.7%) eyes, without differences between groups (p=0.6333).Conclusion: Primary needling, at the time of surgery, was a safe procedure in OAG patients who underwent a XEN implant, although it was not associated with a lower postoperative IOP or less ocular hypotensive medications.Keywords: open-angle glaucoma, MIGS, XEN, primary needling
