Data preservation is a mandatory specification for any present and future experimental facility and it is a cost-effective way of doing fundamental research by exploiting unique data sets in the ...light of the continuously increasing theoretical understanding. This document summarizes the status of data preservation in high energy physics. The paradigms and the methodological advances are discussed from a perspective of more than ten years of experience with a structured effort at international level. The status and the scientific return related to the preservation of data accumulated at large collider experiments are presented, together with an account of ongoing efforts to ensure long-term analysis capabilities for ongoing and future experiments. Transverse projects aimed at generic solutions, most of which are specifically inspired by open science and FAIR principles, are presented as well. A prospective and an action plan are also indicated.
A convective scheme 1D simulation was used to study the coupled transport of H\++\-, H\+v\2\-v\\++\-, and H\+v\3\-v\\++\- ions in hydrogen for high E/N reduced electric fields. Results show that, for ...a weakly dissociated gas, H\+v\3\-v\\++\- ions are dominant for E/N values up to about 2 kTd. (Original abstract-amended)
Accurate measurements are reported of the radiative heat transfer between parallel surfaces of uncoated and doped tin oxide coated glass. The infrared properties of the tin oxide coated glass are ...calculated by a novel approach by fitting a three parameter Drude model to reflectance measurements at a specified angle, and over a restricted range of wavelengths. Estimates of the radiative heat transfer between uncoated and coated glass surfaces are calculated from a consideration of the directional spectral emittances and the blackbody spectrum. This procedure gives results that are in more consistent agreement with experimental measurements than results obtained by considering the hemispherical total, or directional total emittances.
The heat flow through a 1 mx1 m sample of vacuum glazing has been measured in two independent ways. One measurement method uses a guarded hot box to make a direct determination of overall ...heat-transmission coefficient under standard test conditions. The other method uses a small-area guarded hot plate (specially designed for this purpose) to measure the local radiative and (negligible) gas conductance between the glass sheets. This instrument is also used to validate calculations of the heat flow through the support pillars. The overall heat flow is then obtained by combining the contributions from these processes with those due to heat flow through the conducting edge seal. The results obtained with the two methods are in very good agreement for the same external conditions. These results provide the first independent validation of estimates of heat flow through vacuum glazing based on the five separate processes that contribute to this heat transfer.
In this study, the authors examined relations among adult attachment orientations, maladaptive problem coping styles, and a composite measure of current distress within a sample of 55 undergraduates ...(17 men, 38 women). Results indicated that each adult attachment orientation and each problem coping style measure was related in expected directions to students' distress. In addition, problem coping styles largely mediated the impact of insecure adult attachment orientations on distress. Implications of our findings to advancing an attachment theory‐informed perspective on college student coping, distress, and intervention are discussed.
We have reviewed the records of 37 patients with pathologically staged IIIA Hodgkin's disease, treated from 1970 to 1982. Twenty patients were staged IIIA1 and 17 staged IIIA2. Treatment consisted of ...total nodal irradiation in 33 patients (eight of whom received adjuvant MOPP), and mantle plus para-aortic irradiation in four patients (all of whom received adjuvant MOPP). Five-year relapse-free survival (RFS) in patients without splenic involvement was 77% versus 49% for those with splenic involvement (p = 0.43). Five-year RFS in patients treated with irradiation and chemotherapy (RT/CT) was 76% vs. 47% for patients treated with irradiation alone (p = 0.12). RFS was not influenced by sex, mediastinal involvement by tumor, or anatomic substage. Overall survival (corrected for deaths due to intercurrent disease) for the entire group of patients was 92% at 5 years and 87% at 10 years. Sex, mediastinal or splenic involvement by tumor, therapy (RT vs. RT/CT), or anatomic substage did not significantly influence survival. We currently recommend RT/CT only for those patients with extensive splenic involvement and/or Stage IIIA2 disease. We feel that the poor prognosis of these patients justifies the use of RT/CT and its risk of second malignancies.
In this chapter of the High Energy Physics Software Foundation Community Whitepaper, we discuss the current state of infrastructure, best practices, and ongoing developments in the area of data and ...software preservation in high energy physics. A re-framing of the motivation for preservation to enable re-use is presented. A series of research and development goals in software and other cyberinfrastructure that will aid in the enabling of reuse of particle physics analyses and production software are presented and discussed.
