Effects of sediment deposition and interspecific competition on the growth and ecological stoichiometric characteristics of .

With as the competitor species, we set four sedimentation depths (0, 3, 6, and 12 cm) and four competition treatments (no competition, full competition, aboveground competition, and belowground competition) to assess the growth and stoichiometric traits of , a representative wetland plant in Dongting Lake. The results showed that both sedimentation and competition significantly affected the total biomass of . Moderate sedimentation (3-6 cm) facilitated biomass accumulation, whereas excessive sedimentation (12 cm) suppressed growth.

Cold-season macrophyte-driven microbial modulation reduces nutrient release in eutrophic lake sediments.

Submerged macrophyte restoration can effectively regulate internal nutrient cycling in eutrophic lake sediments, yet how cold-season macrophytes influence sediment microbial processes remain poorly understood. In this study, we conducted a field enclosure experiment combined with metagenomic sequencing using Potamogeton crispus, a cold-season submerged macrophyte, to investigate its effects on nitrogen (N) and phosphorus (P) dynamics across the sediment-water interface. The restoration of P.

Advances in RNA secondary structure prediction and RNA modifications: Methods, data, and applications.

Due to the hierarchical organization of RNA structures and their pivotal roles in fulfilling RNA functions, the formation of RNA secondary structure critically influences many biological processes and has thus been a crucial research topic. This review sets out to explore the computational prediction of RNA secondary structure and its connections to RNA modifications, which have emerged as an active domain in recent years. We first examine the progression of RNA secondary structure prediction methodology, focusing on a set of representative works categorized into thermodynamic, comparative, machine learning, and hybrid approaches.

Restoration of submerged vegetation modulates microbial communities to decrease nitrogen and phosphorus loads in sediment-water systems.

The release of nitrogen and phosphorus from sediments, known as internal nutrient loading, plays a crucial role in determining the eutrophic state of lakes and the timeframe for their ecological recovery. The restoration of submerged macrophytes is considered an effective measure to improve lake eutrophication. However, the impact of submerged macrophytes restoration on the storage and transformation mechanisms of nitrogen and phosphorus in lake sediment-water systems has not yet been systematically studied.

Nutrient enrichment, propagule pressure, and herbivory interactively influence the competitive ability of an invasive alien macrophyte .

Introduction: Freshwater ecosystems are susceptible to invasion by alien macrophytes due to their connectivity and various plant dispersal vectors. These ecosystems often experience anthropogenic nutrient enrichment, favouring invasive species that efficiently exploit these resources. Propagule pressure (reflecting the quantity of introduced individuals) and habitat invasibility are key determinants of invasion success.

Adaptive responses and transgenerational plasticity of a submerged plant to benthivorous fish disturbance.

Submerged macrophytes play a key role in the restoration of shallow eutrophic lakes. However, in some subtropical lakes, benthivorous fishes dominate the fish assemblages and influence the growth of submerged plants. A comprehensive understanding of the direct and indirect effects of benthivorous fishes on submerged plants is important.

Community structure and function of epiphytic bacteria attached to three submerged macrophytes.

In aquatic ecosystems, large amounts of epiphytic bacteria living on the leaf surfaces of submerged macrophytes play important roles in affecting plant growth and biogeochemical cycling. The restoration of different submerged macrophytes has been considered an effective measure to improve eutrophic lakes. However, the community ecology of epiphytic bacteria is far from well understood for different submerged macrophytes.

Prevalence and clinical correlates for depression in women with urinary incontinence: a cross-sectional study.

Introduction And Hypothesis: The coexistence of urinary incontinence (UI) and depression has been intensively examined in women. This study aimed to investigate the prevalence and some clinical correlates of depression in women with UI.

Methods: The National Health and Nutrition Examination Survey (NHANE) 2005-2018 was used in this cross-sectional study, and a total of 7250 UI patients were included.

Conductivity-difference-enhanced DC dielectrophoretic particle separation in a microfluidic chip.

A conductivity-difference-based method for increasing dielectrophoretic (DEP) force for particle separation in a microfluidic chip is presented in this paper. By applying a direct-current (DC) voltage across two immiscible electrolyte solutions with a conductivity difference, an enhanced electric field gradient is generated at the liquid-liquid interface. Theoretical analysis based on equivalent circuit theory found that the gradient of the electric field squared increases with the decrease in the conductivity ratio of the two liquids (main channel to the side channel).

The spatiotemporal characteristics of water quality and phytoplankton community in a shallow eutrophic lake: Implications for submerged vegetation restoration.

One of the most serious consequences of eutrophication in shallow lakes is deterioration of water quality, proliferation of phytoplankton and disappearance of submerged macrophytes. After removing herbivorous and plankti-benthivorous fish, submerged macrophyte restoration was utilized at the entire lake (82.7 km) to combat eutrophication and improve water quality in the shallow subtropical aquaculture of Lake Datong.

Stable and Reversible Photoluminescence from GaN Nanowires in Solution Tuning by Ionic Concentration.

We report response of photoluminescence (PL) from GaN nanowires without protection in solutions. The distinct response is not only toward pH but toward ionic concentration under same pH. The nanowires appear to be highly stable under aqueous solution with high ionic concentration and low pH value down to 1.

Secrecy Enhancing Scheme for Spatial Modulation Using Antenna Selection and Artificial Noise.

In this paper, we present a new secrecy-enhancing scheme for the spatial modulation (SM) system, by considering imperfect channel state information (CSI). In the proposed scheme, two antennas are activated at the same time. One of the activated antennas transmits information symbols along with artificial noise (AN) optimized under the imperfect CSI condition.
