Research on high-performance, real-time periodic signal detection method based on field-programmable gate arrays (FPGAs).

Long-Time Coherent Integration (LTCI) utilizes digital integration to combine multiple coherent cycles, thereby improving the signal-to-noise ratio (SNR). Our previous work introduced single-bit LTCI, an approach optimized for FPGA implementation, but faced challenges of output saturation at high SNR levels and inherent limitations in SNR gain (SNRG), which are insufficient for certain applications. This paper presents a threshold tracking method that improves the performance of single-bit LTCI in high-SNR scenarios.

Environment and management jointly shape the spatial patterns of plant species diversity of moist grasslands in the mountains of northeastern Yunnan.

Grasslands account for about a quarter of the Earth's land area and are one of the major terrestrial ecosystems, with significant ecological and economic values. The influence of environmental factors and management types on grassland biodiversity has garnered considerable attention. This study investigated how patterns of species richness are influenced by geographical distance, environmental gradients, and management type in the moist mountain grasslands of northeastern Yunnan, China.

Proximal Oblique-Packing of Heptamethine Cyanines through Spiro-Connection Boosts Triplet State Generation in Near-Infrared.

Near-infrared (NIR) triplet dyes are the cornerstones of cutting-edge biomedical and material applications. The difficulty in rational development of triplet dyes increases exponentially as the absorption wavelength shifts deeper into the NIR range. Although classical H-/J-typed packing of NIR dyes has the potential to enhance intersystem crossing (ISC) compared with that in single-chromophore dyes, the triplet state quantum yields remain limited in such strategy.

Integrated ecological-health risk assessment of ofloxacin.

Antibiotics are emerging contaminants of significant concern, while previous research has mostly focused on their ecological or health impacts in isolation. This limited systematic research on its overall risk and the uncertainty relating to the risk evaluation is also unclear. This study addressed this gap by examining both ecological or health impacts by integrating interspecies correlation models, species sensitivity distribution curves, and health risk evaluation.
