A novel method for the absolute fluorescence yield measurement by AIRFLY

One of the goals of the AIRFLY (AIR FLuorescence Yield) experiment is to measure the absolute fluorescence yield induced by electrons in air to better than 10% precision. We introduce a new technique for measurement of the absolute fluorescence yield of the 337 nm line that has the advantage of reducing the systematic uncertainty due to the detector calibration. The principle is to compare the measured fluorescence yield to a well known process - the Cerenkov emission. Preliminary measurements taken in the BFT (Beam Test Facility) in Frascati, Italy with 350 MeV electrons are presented. Beam tests in the Argonne Wakefield Accelerator at the Argonne National Laboratory, USA with 14 MeV electrons have also shown that this technique can be applied at lower energies.Comment: presented at the 5th Fluorescence Workshop, El Escorial - Madrid, Spain, 16 - 20 September 200

Identification of the unfavored N=7 superdeformed band in Hg191

A new superdeformed band has been identified in Hg191 bringing the total number of bands observed in this nucleus to four. The new band has properties similar to those of a superdeformed band reported recently in Hg193. Both bands are believed to be built on the unfavored signature of the j15/2 intruder configuration. Comparisons between the data and cranked Woods-Saxon calculations highlight the strengths and weaknesses of theory in describing high-N orbitals at large deformation

New features of superdeformed bands in Hg194

Two new features of superdeformed (SD) bands in the A190 region emerge from a study of Hg194 with the Gammasphere detector array. A decrease of the dynamic moment of inertia is observed for rotational frequencies Latin small letter h with strokeω0.4 MeV, confirming long standing expectations based on mean field calculations with pairing. Evidence for a small staggering in the SD transition energies is also observed, suggesting the presence of terms with fourfold symmetry in the SD Hamiltonian

Editorial Statement About JCCAP’s 2023 Special Issue on Informant Discrepancies in Youth Mental Health Assessments: Observations, Guidelines, and Future Directions Grounded in 60 Years of Research

Issue 1 of the 2011 Volume of the Journal of Clinical Child and Adolescent Psychology (JCCAP) included a Special Section about the use of multi-informant approaches to measure child and adolescent (i.e., hereafter referred to collectively as “youth”) mental health (De Los Reyes, 2011). Researchers collect reports from multiple informants or sources (e.g., parent and peer, youth and teacher) to estimate a given youth’s mental health. The 2011 JCCAP Special Section focused on the most common outcome of these approaches, namely the significant discrepancies that arise when comparing estimates from any two informant’s reports (i.e., informant discrepancies). These discrepancies appear in assessments conducted across the lifespan (Achenbach, 2020). That said, JCCAP dedicated space to understanding informant discrepancies, because they have been a focus of scholarship in youth mental health for over 60 years (e.g., Achenbach et al., 1987; De Los Reyes & Kazdin, 2005; Glennon & Weisz, 1978; Kazdin et al., 1983; Kraemer et al., 2003; Lapouse & Monk, 1958; Quay et al., 1966; Richters, 1992; Rutter et al., 1970; van der Ende et al., 2012). Thus, we have a thorough understanding of the areas of research for which they reliably appear when clinically assessing youth. For instance, intervention researchers observe informant discrepancies in estimates of intervention effects within randomized controlled trials (e.g., Casey & Berman, 1985; Weisz et al., 2017). Service providers observe informant discrepancies when working with individual clients, most notably when making decisions about treatment planning (e.g., Hawley & Weisz, 2003; Hoffman & Chu, 2015). Scholars in developmental psychopathology observe these discrepancies when seeking to understand risk and protective factors linked to youth mental health concerns (e.g., Hawker & Boulton, 2000; Hou et al., 2020; Ivanova et al., 2022). Thus, the 2011 JCCAP Special Section posed a question: Might these informant discrepancies contain data relevant to understanding youth mental health? Suppose none of the work in youth mental health is immune from these discrepancies. In that case, the answer to this question strikes at the core of what we produce―from the interventions we develop and implement, to the developmental psychopathology research that informs intervention development

Ocorrência de poliúria-polidpsia em eqüinos estabulados - descrição de dois casos de polidipsia psicogênica Incidence of two cases of polyuria-polydipsia in confined horses

Dois eqüinos da raça Brasileira de Hipismo, machos, quatro anos de idade, apresentando sinais de poliúria-polidipsia, foram submetidos a completa avaliação clínica e a exames de sangue e urina. Não foram observadas alterações clínicas, hematológicas ou bioquímicas, a não ser um decréscimo na gravidade específica da urina de ambos os animais (1,009 e 1,008). Realizou-se um teste de privação de água de 24 horas e durante esse período a gravidade especifica da urina subiu gradualmente até atingir a normalidade (1,028 e 1,026, respectivamente). O comportamento anormal ocorreu por confinamento excessivo. Os resultados clínicos e de laboratório e o teste de privação de água indicam o diagnóstico de polidipsia psicogênica.<br>Two four-year-old male Brasileiro de Hipismo breed horses presenting signs of polyuria-polydipsia, were submitted to a complete clinical evaluation as well as having blood and urine samples collected for laboratory analysis. No clinical, hematological or biochemical abnormalities were observed, but a significant decrease in urine specific gravity was detected in both horses. One of the horses presented 1,009 and the other 1,008. A 24-hour water deprivation test was carried out and, during this period, the urine specific gravity gradually increased reaching the normal values of 1,028 and 1,026. The abnormal behavior occured as a consequence of an excessive confinement. The clinical and laboratory results associated to the 24-hour water deprivation test indicated a diagnosis of psychogenic polydipsia
