Physics – Expanding Climate Stripes
• Physics 18, 119
In bringing attention to climate change, this year’s Show Your Stripes Day includes new stripe patterns depicting temperature changes in the ocean and atmosphere, as well as in future-climate scenarios.
Climate science and the case of the missing moisture
Simpson and colleagues found expected moisture missing over all of the world’s arid and semi-arid regions, an area covering about 20% of Earth’s land, including the US Southwest, South Africa, Somalia, Central Australia, and parts of Asia….

Analysis of gamma spectrometry
The spectrum of the black disperse dye sample is shown on Fig. 3. The highest average concentrations of 238U, 226Ra, 232Th, and 40K in disperse dyes were 19.14 ± 5.17, 27.15 ± 6.23, 8.03 ± 2.26, and…

Few-fermion resonant tunneling and underbarrier trapping in asymmetric potentials
Model
In classical physics, a particle cannot penetrate a potential barrier if its energy is lower than the barrier’s potential energy. However, quantum mechanics introduces the concept of tunneling, allowing a particle to pass through the…
