Constructing urban habitat networks can effectively improve the stability of regional ecosystems, increase energy flow and gene exchange in landscape patches, and play a crucial role in urban biodiversity conservation. With urban area of Shenyang City as the study area, we identified the source of bird habitats from three dimensions: morphology-quality-neighborhood. From the three dimensions of environmental elements, architectural index, and anthropogenic interference, we superimposed 12 resistance factors to construct resistance surfaces.

Black phosphorus nanoribbons (BPNRs) with a tunable bandgap and intriguing electronic and optical properties hold strong potential for logic applications. However, efficiently producing high-quality BPNRs with precise control over their size and structure remains a great challenge. Here we achieved high-quality, narrow and clean BPNRs with nearly atomically smooth edges and well-defined edge orientation at high yield (up to ~95%) through the sonochemical exfoliation of the synthesized bulk BP crystals with a slightly enlarged lattice parameter along the armchair direction.

Skin autofluorescence (SAF) detection technology represents a noninvasive, convenient, and cost-effective optical detection approach. It can be employed for the differentiation of various diseases, including metabolic diseases and dermatitis, as well as for monitoring the treatment efficacy. Distinct from diffuse reflection signals, the autofluorescence signals of biological tissues are relatively weak, making them challenging to be captured by photoelectric sensors.

Dark excitonic states play a pivotal role in controlling the radiative dynamics of low-dimensional luminescent materials. In this work, we investigate dark states of an emerging zero-dimensional (0D) organic-inorganic hybrid metal halide that diverge markedly from traditional inorganic and organic semiconductors. Our studies reveal that when the dark states dominate the emission, the 0D material exhibits an anomalous giant magneto-blueshift of approximately 9 meV at 7 T.

Exploring the internal relationship between the structure and properties of AIE-active iridium complexes and their applications have been great significance. It is imperative to acknowledge that the precise control of nanoparticle morphology and particle size of organic molecules in solutions remains elusive, while comprehending the luminescent mechanisms of self-assembled aggregates continues to present a challenge. The previously work proposed that solvent-induced amphiphilic molecules could enhance the self-assembly properties of iridium complexes, but the influence of ligands' hydrophilic-lipophilic interactions on the AIE characteristics of iridium complexes remained unclear.

Enhancing crop production and yield is necessary to feed an increasing population, but cadmium (Cd) accumulation in crops poses a serious threat to human health. It is found that a trend during domestication is for the co-selection of improved tomato yield and reduced Cd accumulation. A genome-wide association study (GWAS) of 506 tomato accessions identifies a natural allele, LCT1, which confers low Cd accumulation in the shoots and fruits of tomato.

Plant growth is inseparable from the presence of mineral nutrients such as nitrogen (N), phosphorus (P), and potassium (K), but the mechanism by which horticultural plants such as tomatoes respond to mineral elements is poorly understood. Here, we collected 28 phenotypic datasets, including 5 agronomic traits and 4 pigment accumulation traits, under full nutrition and nitrogen/phosphorus/potassium-deficiency conditions, most of which showed abundant variation. Phenotyping analysis suggested that the yellowing of leaves under low-nitrogen treatment was caused by an increase in the carotenoid content and a decrease in the chlorophyll content.

With the increasing development of 6th-generation (6G) air-to-ground (A2G) communications, the combination of millimeter-wave (mmWave) and multiple-input multiple-output (MIMO) technologies can offer unprecedented bandwidth and capacity for unmanned aerial vehicle (UAV) communications. The introduction of new technologies will also make the UAV channel characteristics more complex and variable, posing higher requirements for UAV channel modeling. This paper presents a novel predictive channel modeling method based on Transformer architecture by integrating data-driven approaches with UAV air-to-ground channel modeling.

Heparin cofactor II (HCII) is a critical anticoagulant protein that inactivates thrombin. In our previous mouse studies, we demonstrated that GalNAc-HCII, a small interfering RNA (siRNA) targeting HCII conjugated with N-acetylgalactosamine (GalNAc), exhibited promising therapeutic effects in hemophilia A mouse models. Further evaluation in large animal models, especially with FVIII inhibitors, is essential before GalNAc-HCII can proceed to clinical trials.
