The joint evaluated fission and fusion nuclear data library, JEFF-3.3
AbstractThe joint evaluated fission and fusion nuclear data library 3.3 is described. New evaluations for neutron-induced interactions with the major actinides$$^{235}\hbox {U}$$235U,$$^{238}\hbox {U}$$238Uand$$^{239}\hbox {Pu}$$239Pu, on$$^{241}\hbox {Am}$$241Amand$$^{23}\hbox {Na}$$23Na,$$^{59}\hbox {Ni}$$59Ni, Cr, Cu, Zr, Cd, Hf, W, Au, Pb and Bi are presented. It includes new fission yields, prompt fission neutron spectra and average number of neutrons per fission. In addition, new data for radioactive decay, thermal neutron scattering, gamma-ray emission, neutron activation, delayed neutrons and displacement damage are presented. JEFF-3.3 was complemented by files from the TENDL project. The libraries for photon, proton, deuteron, triton, helion and alpha-particle induced reactions are from TENDL-2017. The demands for uncertainty quantification in modeling led to many new covariance data for the evaluations. A comparison between results from model calculations using the JEFF-3.3 library and those from benchmark experiments for criticality, delayed neutron yields, shielding and decay heat, reveals that JEFF-3.3 performes very well for a wide range of nuclear technology applications, in particular nuclear energy.
Celestial Symphony: Harmonizing Worlds
"Celestial Symphony: Harmonizing Worlds" captures a mesmerizing celestial scene where the ethereal dance of stars, planets, and galaxies unfolds against the canvas of the night sky. Radiant hues of blues and purples blend seamlessly, casting a soothing glow that envelops the viewer. The juxtaposition of celestial bodies in varying sizes creates a sense of depth, guiding the gaze towards a radiant nebula at the heart of the composition. This artwork encapsulates the cosmic beauty and unity of the universe, inviting contemplation on the interconnectedness of distant worlds and our place within the cosmos.
Computational Social Science and Sociology
The integration of social science with computer science and engineering fields has produced a new area of study: computational social science. This field applies computational methods to novel sources of digital data such as social media, administrative records, and historical archives to develop theories of human behavior. We review the evolution of this field within sociology via bibliometric analysis and in-depth analysis of the following subfields where this new work is appearing most rapidly: ( a) social network analysis and group formation; ( b) collective behavior and political sociology; ( c) the sociology of knowledge; ( d) cultural sociology, social psychology, and emotions; ( e) the production of culture; ( f) economic sociology and organizations; and ( g) demography and population studies. Our review reveals that sociologists are not only at the center of cutting-edge research that addresses longstanding questions about human behavior but also developing new lines of inquiry about digital spaces as well. We conclude by discussing challenging new obstacles in the field, calling for increased attention to sociological theory, and identifying new areas where computational social science might be further integrated into mainstream sociology.
The Effect of an 8-Week Low- or High-Volume Protocol of the Adductor Strengthening Programme on Hip Adduction Strength in Female Football Players-A Randomized Trial.
The aim of this study was to investigate if an 8-week high-volume protocol of the Adductor Strengthening Programme was more effective than a low-volume protocol in increasing and maintaining isometric hip adduction strength in female football players. We randomized 52 players from the Norwegian women's 1st and 2nd division to a low-volume (220 reps/side) or high-volume (394 reps/side) group. Both groups performed an 8-week protocol of the Adductor Strengthening Programme and a 10-week maintenance protocol with 1 session/week (16 reps/side/session). We measured isometric hip adductor torque (Nm/kg) in a long-lever squeeze test (at 0° and 15° hip abduction) using the ForceFrame at baseline, weeks 4, 6, 8, and 18. Both groups increased their isometric hip adduction strength over the 8-week period (low-volume 0°: 0.13 [95% CI: 0.07-0.20] Nm/kg, 15°: 0.22 [95% CI: 0.07-0.36] Nm/kg; high-volume 0°: 0.13 [95% CI: 0.04-0.22] Nm/kg, 15°: 0.31 [95% CI: 0.18-0.45] Nm/kg), with no between-group difference in either test position (0°: -0.01 [95% CI: -0.11-0.01] Nm/kg; 15°: 0.10 [95% CI: -0.09-0.29] Nm/kg). Also, both groups maintained their strength throughout the 10-week maintenance period, with no between-groups difference in either test position (0°: 0.12 [95% CI: -0.01-0.24] Nm/kg; 15°: 0.06 [95% CI: -0.11-0.23] Nm/kg). Our results indicate that an 8-week high-volume protocol of the Adductor Strengthening Programme was not more effective in increasing isometric adductor strength in female football players than a low-volume protocol. Both groups increased their strength over the 8-week training period and maintained their strength during the 10-week maintenance period. Trial registration: The study protocol was uploaded to Open Science Framework before unblinding and analyzing the data (https://osf.io/7xfw4/).
