G-quadruplexes constitute a class of nucleic acid structures defined by stacked guanine tetrads (or G-tetrads) with guanine bases from neighboring tetrads stacking with one another within the G-tetrad core. Individual G-quadruplexes can also stack with one another at their G-tetrad interface leading to higher-order structures as observed in telomeric repeat-containing DNA and RNA. In this study...

Soil organic carbon (SOC) and nitrogen (N) fractions greatly affect soil health quality. This study explored the effects of wheat straw incorporation on Chinese rice paddy fields with four treatments: (1) a control (CK), (2) mineral NPK fertilizer (NPK), (3) moderate (3 t ha?1) plus (MSNPK), (4) high (6 (HSNPK). In total, 0–5, 5–10, 10–20, 20–30 cm depths were sampled from in China. Compared CK...

We present the first characterization of circumgalactic medium Ly$\alpha$ emitters (LAEs), using a sample 96 $z\approx3.3$ LAEs detected with VLT/MUSE in fields centered on 8 bright background quasars. The have low luminosities ($\sim 10^{42}\,\text{erg}\,\text{s}^{-1}$) and star formation rates (SFRs) $\sim 1~\text{M}_\odot\,\text{yr}^{-1}$, which for main sequence galaxies corresponds to stel...

Background: Soil microorganisms play key roles in nutrient cycling and are distributed throughout the soil profile. Currently, there is little information about the characteristics of the microbial communities along the soil depth because most studies focus on microorganisms inhabiting the soil surface. To better understand the functions and composition of microbial communities and the biogeoch...

Objective: Soil temperature serves as a key variable in hydrological investigations to determine soil moisture content as well as hydrological balance in watersheds. The ingoing research aims to shed lights on potential of artificial neural networks (ANNs) and Neuro-Fuzzy inference system (ANFIS) to simulate soil temperature at 5-100 cm depths. To satisfy this end, climatic and...

It is shown that the minimum possible number of edges in an n-superconcentrator of depth 3 is Θ(n log log n), whereas the minimum possible number of edges in an n-superconcentrator of depth 2 is Ω(n(log n) 3/2) (and is O(n(log n) 2)).
