Abstract Osteoporosis poses substantial challenges for biomaterials implantation. New approaches to improve bone‐implant integration should resolve the fundamental dilemma of inflammation—proper inflammation is required at early stages but be suppressed later better healing, especially under osteoporosis. However, precisely switching on and off around implants in vivo remains unachieved. To address this challenge, a “bridge‐burning” coating material that comprises macrophage‐activating...
Hair loss affects over 50 million people worldwide with limited therapeutic options. Despite evidence highlighting the vital role of local immune cells in regulating life cycle hair follicles (HFs), accurate regulation immunocytes to directly promote growth remains unachieved. Here, inspired by physiological feedback skin immunity suppress microbe-triggered inflammation, an oligosaccharide biomaterial "unmasked" specific activity is developed recruit regulatory T (T
A 28 GHz millimeter-wave (mm-wave) propagation measurement campaign was performed to predict the multiple-input multiple-output (MIMO) channel performance in a tunnel environment. Two kinds of polarization configurations were studied this paper. In order overcome serious path loss (PL) mm-wave propagation, high gain directional horn antenna used measurements The results and simulation at same specific locations are compared. result comparison indicates that model matches well. Then MIMO...
SPARQL is a highly powerful query language for an ever-growing number of Linked Data resources and Knowledge Graphs. Using it requires certain familiarity with the entities in domain to be queried as well expertise language's syntax semantics, none which average human web users can assumed possess. To overcome this limitation, automatically translating natural questions queries has been vibrant field research. However, date, vast success deep learning methods not yet fully propagated...
This study studies the multiple‐input–multiple‐output (MIMO) performance in a tunnel scenario for millimetre‐wave (mm‐wave) band. We simulated and measured channel impulse response at 28 GHz grids of transmitters receivers to feasibility mm‐wave MIMO system metro communication environment.

This letter investigates the channel propagation characterization in a short tunnel through time-domain measurement at 28-GHz frequency band. The statistic parameters of channel, such as root-mean-square delay spread (RMS-DS), K-factor, and shadowing are studied, results reveal that align better to normal distribution. RMS-DS is positively correlated with but negatively K-factor. We also deduced K-factor shadowing. From angular measurements, it inferred signal around 0° 180° directions,...
The global pandemic of COVID-19 highlights the importance vaccination, which remains most efficient measure against many diseases. Despite progress in vaccine design, concerns with suboptimal antigen immunogenicity and delivery efficiency prevail. Self-adjuvant carriers–vehicles that can simultaneously deliver antigens act as adjuvants–may improve efficacies these aspects. Here, we developed a self-adjuvant carrier based on an acetyl glucomannan (acGM), activate toll-like receptor 2 (TLR2)...
