Respiration is a major vital sign, which can be used for early illness diagnosis and physiological monitoring. Wearable respiratory sensors present an exciting opportunity to monitor human behaviors in real-time, noninvasive, comfortable way. Among them, fiber-shaped triboelectric nanogenerators (FS-TENGs) are attractive their comfort high degree of freedom. However, the single-electrode FS-TENGs cannot respond own tensile strains, coaxial double-electrode show low sensitivity strain due...

Hemispherical (fisheye) photography is a well-established approach for estimating the sky view factor (SVF). High-resolution urban models from LiDAR and oblique airborne photogrammetry can provide continuous SVF estimates over large area, but such data are not always available difficult to acquire. Street panoramas have become widely in areas worldwide: Google View (GSV) maintains global network of excluding China several other countries; Baidu (BSV) Tencent (TSV) focus their panorama...
The development of elastic electronic technology has promoted the application triboelectric nanogenerators (TENGs) in flexible wearable electronics. However, most electronics cannot achieve requirements being extremely stretchable, transparent, and highly conductive at same time. Herein, we report a TENG constructed using double-network polymer ionic conductor sodium alginate/zinc sulfate/poly acrylic-acrylamide (SA–Zn) hydrogel, which exhibited outstanding stretchability (>10,000%), high...

Further, in vitro biodegradation CSF performed through trypsin lysozyme. The results show that lysozyme have...
The rapid development of wearable electronics requires its energy supply part to be flexible, wearable, integratable and sustainable. However, some the units cannot meet these requirements at same time, there is also a capacity limitation storage units, sustainable self-charging power supplies crucial. Here, we report harvesting-storage hybrid textile. textile consists coaxial fiber-shaped polylactic acid/reduced graphene oxide/polypyrrole (PLA-rGO-PPy) triboelectric nanogenerator...
Abstract It is of great importance to explore a creative route improve the degradation efficiency organic pollutants in wastewater.

The power output be...
Virtual geographic environments (VGEs) are extensively used to explore the relationship between humans and environments. Crowd simulation provides a method for VGEs represent crowd behaviors that observed in real world. The social force model (SFM) can simulate interactions among individuals, but it has not sufficiently accounted inter-group intra-group which important components of dynamics. We present group (SGFM), based on an extended SFM, with focuses avoiding different groups coordinate...
The importance of ocean exploration and underwater monitoring is becoming vital, due to the abundant biological, mineral, energy, other resources in ocean. Here, a self-powered cable-based triboelectric nanogenerator (TENG) demonstrated for mechanical motion/triggering, as well searching rescuing sea. Using novel double-layer winding method combined with ferroelectric polarization, cable-structured sensor stable electrical output has been manufactured, which can accurately respond variety...
The continued 'evolution' of Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has led to the emergence Omicron variant after Delta variant, resulting in a significant increase number people with COVID-19. This cases continues have impact on lives. Therefore, more detailed understanding clinical characteristics infection is essential.Using medical charts, we extracted information for 384 patients infected Anyang City, Henan Province, China. Epidemiology and were compared cohort...

Oblique airborne photogrammetry-based three-dimensional (3D) city model (OAP3D) provides a spatially continuous representation of urban landscapes that encompasses buildings, road networks, trees, bushes, water bodies, and topographic features. OAP3D is usually present in the form group unclassified triangular meshes under multi-resolution data structure. Modifying such non-separable landscape constitutes daunting task because manual mesh editing normally required. In this paper, we...

Abstract Optimizing the spatial configuration of diverse best management practices (BMPs) can provide valuable decision‐making support for comprehensive watershed management. Most existing methods focus on selecting BMP types and locations but neglect their implementation time or order in scenarios, which are often investment‐restricted. This study proposes a new simulation‐optimization framework determining plan BMPs by using net present value to calculate economic costs scenarios...

At present, a common drawback of crowd simulation models is that they are mainly simulated in (abstract) 2D environments, which limits the behaviors observed real 3D environments. Therefore, we propose deep reinforcement learning-based model with human-like perceptron and policy for evacuation environments (HDRLM3D). In HDRLM3D, vision-like ray (VLRP) combine it redesigned global (or local) (GOLP) to form perception model. We double-branch feature extraction decision network (DBFED-Net) as...
