Abstract. Long-term monitoring of regulated organic chemicals, such as legacy persistent pollutants (POPs) and polycyclic aromatic hydrocarbons (PAHs), in ambient air provides valuable information about the compounds' environmental fate well temporal spatial trends. This is foundation to evaluate effectiveness national international regulations for priority pollutants. Extracts high-volume samp...

We study the level-set of zero-average Gaussian Free Field on a uniform random d-regular graph above an arbitrary level h∈(−∞,h⋆), where h⋆ is percolation threshold GFF tree Td. prove that w.h.p as number n vertices diverges, has unique giant connected component C1(n) size η(h)n+o(n), η(h) probability root percolates in corresponding This gives positive answer to conjecture [4] for most regular...

Abstract In this paper, we obtain bounds on the Wilson loop expectations in 4D $U(1)$ lattice gauge theory, which quantify effect of topological defects. case a Villain interaction, by extending non-perturbative technique introduced [24], following estimate for large $\gamma $ at low temperatures: |\langle W_\gamma \rangle _{\beta }|\leq \exp \Big (-\frac {C_{GFF}} {2\beta }(1+C \beta e^{- 2\pi...

Ship detection in synthetic aperture radar (SAR) images is a significant and challenging task. However, most existing deep learning-based SAR ship approaches are confined to single-polarization fail leverage dual-polarization characteristics, which increases the difficulty of further improving performance. One problem that requires solution how make full use characteristics excavate polarizatio...

The hydrogenation of furfural is an important process in the synthesis bio-based chemicals. Copper-based catalysts favor to alcohols. Catalytic activity and stability were higher at a Ni-to-Cu atomic ratio 1:1 1.5:0.5 compared 0.5:1.5. Here, we prepared Ni-Cu/Al2O3 derived from layered double hydroxides (LDHs). Catalysts calcined 673 K reduced 773 with nominal Ni/Cu ratios y/x = 1.5/0.5, 1/1 0....
