Wavelengths and estimated intensities for 1791 lines of neutral ytterbium in the region 2155 to 31 308 Å are reported. The Zeeman effect has been investigated for 249 of these lines. Analysis of the data has resulted in classification of 787 lines as transitions between 102 even and 77 odd levels. Even levels have been assigned to the electron configurations 4 6 (the ground state), 4 6, 4 6, 4 6 6, 4 6 , 4 5 , and 4 566. Odd levels have been assigned to 4 6, 4 6, and 4 56 . Many odd levels are still unassigned, but the majority undoubtedly belong to the configuration 4 5 6.

The continuous evolution of information technology underscores the growing emphasis on data security. In the realm of medical imaging, various diagnostic images represent the privacy of individuals, and the potential repercussions of their unauthorized disclosure are substantial. Therefore, this study introduces a novel chaotic system (TLCMCML) and employs it to propose a multi-image medical image encryption algorithm.

The hydroxysilylene (HSiOH) molecule has been spectroscopically identified in the gas phase for the first time. This highly reactive species was produced in a twin electric discharge jet using separate precursor streams of 16O2/18O2 and Si2H6/Si2D6, both diluted in high pressure argon. The strongest and most stable laser induced fluorescence (LIF) signals were obtained by applying an electric discharge to each of the precursor streams and then merging the discharge products just prior to expansion into vacuum.

Background: Occupational noise has been associated with numerous adverse health outcomes. However, limited evidence exists regarding its association with obesity. We aim to investigate the effect of occupational noise exposure on the risk of overweight/obesity among workers, providing scientific evidence for the prevention and management of overweight/obesity in the occupational population.

We describe an agent-based model purposed for social learning, which was developed by stakeholders, with the technical assistance of professional modelers, to facilitate stakeholder involvement in modeling issues related to the development of an adaptive environmental management plan for the Texas Gulf Coast (USA) estuaries. Stakeholders developed the model during six workshops that spanned a three-year period, and used the model to simulate the population dynamics (recruitment, growth, movement, and mortality) of blue crabs () in the Aransas and Copano Bays in response to various freshwater inflow and harvest scenarios. Results of scenarios representing normal, low, and high harvest levels indicated little effect on blue crab abundances, but harvests increased ≈75 % when harvest level was doubled and decreased ≈50 % harvest level was halved.

However, the increasing prevalence of physical inactivity combined with high screen time use among adolescents is a growing concern. Parents play an important role in shaping adolescents' physical activity and screen time levels through active participation and involvement.
