  • Narrow-band acceleration of gold ions to GeV energies from ultra-thin foils

    Experimental results Figure 1a shows a schematic of the experimental setup at Vulcan, the details of which can be found in the Methods section. Figure 1e, f, g shows the Au ion spectra obtained using Thomson parabola spectrometers (TPS) directed along three observation lines, from the interaction with a 15 nm (black) and a 30 nm (red)…

  • Diversifying crop rotation increases food production, reduces net greenhouse gas emissions and improves soil health

    The field experiment was established in October 2016 at the Luancheng Agro-Ecosystem Station of the Chinese Academy of Sciences (37°50′ N, 114°40′ E; altitude, 50.1 m) in Luancheng County, Hebei Province (Fig. S5a), which represents the agricultural production and climate conditions of the North China Plain. The experimental area experiences a warm, temperate zone, semi-humid, monsoon climate…

  • Electrical tuning of branched flow of light

    Theory of branched flow of light in liquid crystal film According to the Ericksen-Leslie theory, the optical properties of liquid crystals can be characterized by the spatial distribution of molecules’ orientation vector (or the “director”) \(\hat{{{{{{{{\bf{n}}}}}}}}}({{{{{{{\bf{r}}}}}}}})\)31,32. This unit vector determines the local average molecular orientation. Due to the optical birefringence, a uniform NLC system supports…

  • TESOS: an integrated approach for uniform mesoscale imaging

    The Transparent Embedding Solvent System, an innovative imaging method, integrates tissue clearing and section-reconstruction imaging, ensuring consistent sub-micron resolution. This technique is adaptable and compatible with various imaging platforms and specimens. Recently, there has been a profound interest in gaining deeper insights into large biological samples to unravel structural and functional intricacies. 3D large-volume optical…

  • A naturally occurring variant of SHLP2 is a protective factor in Parkinson’s disease

    Human cohorts Health Retirement Study (HRS) Participants Data are from the Health and Retirement Study (HRS), a nationally representative sample of older Americans over age 50 [19, 20] in the contiguous United States. The present analysis was limited to participants who self-reported their race as white/Caucasian, verified by principal components analysis of ancestry markers, in…
