YOLOv8-LCNET: An Improved YOLOv8 Automatic Crater Detection Algorithm and Application in the Chang'e-6 Landing Area.

The Chang'e-6 (CE-6) landing area on the far side of the Moon is located in the southern part of the Apollo basin within the South Pole-Aitken (SPA) basin. The statistical analysis of impact craters in this region is crucial for ensuring a safe landing and supporting geological research. Aiming at existing impact crater identification problems such as complex background, low identification accuracy, and high computational costs, an efficient impact crater automatic detection model named YOLOv8-LCNET (YOLOv8-Lunar Crater Net) based on the YOLOv8 network is proposed.

Integrated Wearable Flexible Hydrogel Patch Sensing System for the Detection of Physiological Markers.

Conventional wearable flexible sensing systems typically comprise three components: a flexible substrate that contacts the skin, a signal processing module, and a signal output module. These components function relatively independently, resulting in a complex system that lacks sufficient integration. Therefore, developing an integrated wearable flexible sensing system by combining the flexible substrate, the signal processing module, and the signal output module not only enhances performance and comfort, but also reduces manufacturing costs and the risk of failure.

The driving effect of polycentric city network on the coordinated development of regional economy in Bohai Rim region of China.

Using social network analysis and spatial Dubin model, this study analyzes the data from the Bohai Rim Economic Zone between 2003 and 2019 and examines the driving effect and mechanism of polycentric urban networks on the regional economic coordination of the Bohai Rim Economic Zone of China from the perspective of combining agglomeration externality and network externality. The results show that: There is a positive correlation between the polycentric degree of the city network in the Bohai Rim Region and its coordinated economic development level; After controlling the classical production factors such as physical capital, non-central cities narrow the gap between their per capital income level and the central cities, and produce positive spatial spillover effects by increasing the relative node centrality in the process of embedding in the polycentric urban network; On the whole, small and medium-sized cities gain node agglomeration growth effect, medium-sized cities play a positive spillover effect, and large cities with node centers play a long wave radiation effect, breaking through geographical proximity-these three factors are interlocked. This research offers pivotal insights for refining the spatial configuration of the Bohai Economic Rim.

Therefore, it is crucial to integrate self-reduction-based adsorption with electrochemical detection.

Water use efficiency in tropical plants based on a set of newly created leaf photosynthesis-related parameters.

Water use efficiency (WUE) quantifies the amount of water expended per unit of dry leaf matter accumulated, reflecting the trade-offs between water consumption and carbon uptake. It is also a critical parameter for understanding plant responses to environmental changes. This study introduced an innovative set of WUE-related parameters, including maximum water use efficiency (WUE) and associated coefficients of water potential, loss, strategic usage, and total usage (WPC, WLC, WSC, and WTC, respectively) in providing a comprehensive evaluation of water use strategies in 48 common tropical plant species during the natural light fluctuations.

Enhanced Anti-inflammatory Effects of Diclofenac Delivered Orally via Polyvinylpyrrolidone K30/Silk Fibroin Nanoparticles in a Murine Model of Carrageenan-Induced Paw Edema.

Diclofenac has a relatively low oral bioavailability (50-60 %) and is quickly metabolized with a half-life of less than 1 h. Therefore, the oral therapeutic effect of diclofenac is not optimal. This research developed polyvinylpyrrolidone K30-functionalized silk fibroin nanoparticles as an effective delivery system for diclofenac (FNPs-PVP-DC).

A new family of thiolate-bridged bimetallic complexes featuring a benzimidazole moiety: synthesis, structure and redox reactivity.

Thiolate-bridged bimetallic complexes have attracted considerable attention owing to their extensive applications in bioinspired catalysis as biological metalloenzymes. Compared with bimetallic complexes supported by common thiolate ligands, those featuring functional groups that may adopt different patterns to coordinate to the metal centers are usually difficult to access, limiting their exploration. The benzimidazole moiety is a multi-faceted functional group; for example, it can act as a biomolecule-responsive ligand for the development of transition metal complexes with anticancer and antitumor properties.

LostNet: A smart way for lost and find.

The rapid population growth in urban areas has led to an increased frequency of lost and unclaimed items in public spaces such as public transportation, restaurants, and other venues. Services like Find My iPhone efficiently track lost electronic devices, but many valuable items remain unmonitored, resulting in delays in reclaiming lost and found items. This research presents a method to streamline the search process by comparing images of lost and recovered items provided by owners with photos taken when items are registered as lost and found.

High-efficiency all-optical switching based on broadband coherent perfect absorption in an atom-cavity system.

We propose an ultrahigh-efficiency and broadband all-optical switching scheme based on coherent perfect absorption (CPA) in linear and nonlinear excitation regimes in a cavity quantum electrodynamics (CQED) system. Two separate atomic transitions are excited simultaneously by two signal fields coupled from two ends of an optical cavity under the collective strong coupling condition. Three polariton eigenstates are produced which can be tuned freely by varying system parameters.

Macroscopic entanglement between ferrimagnetic magnons and atoms via crossed optical cavities.

We consider a two-dimensional opto-magnomechanical (OMM) system including two optical cavity modes, a magnon mode, a phonon mode, and a collection of two-level atoms. We show how the stationary entanglement between two-level atoms and magnons can be achieved. The presence of two optical cavities leads the atom-magnon entanglement to be achieved in a wide parameter regime.
