The administration of bone mesenchymal stem cells (BMSCs) could reverse experimental colitis, and the predominant mechanism in tissue repair seems to be related their paracrine activity. BMSCs derived extracellular vesicles (BMSC-EVs), including mcirovesicles exosomes, containing diverse proteins, mRNAs micro-RNAs, mediating various biological functions, might a main for cell injured communication. We aimed investigate potential alleviating effects BMSC-EVs 2,4,6-trinitrobenzene sulfonic...
With the increasing demand for location awareness, indoor positioning has gradually become one of research hotspots. In recent years field generally introduced dilution precision (DOP) in satellite navigation to optimization base station (BS) configuration, but practice, distribution DOP and errors is far from same. This paper analyzes applicability time difference arrival (TDOA) systems various aspects. Then, according ultrawideband (UWB) ranging error model, TDOA time-difference...
Nowadays, urban noise emerges as a distinct threat to people’s physiological and psychological health. Previous works mainly focus on the measurement mapping of by using Wireless Acoustic Sensor Networks (WASNs) further propose some methods that can effectively reduce pollution in environments. In addition, research combination environmental acoustic events recognition are rapidly progressing. real-life application, there still exists challenges hardware design with enough computational...
Delay, cost, and loss are low in Low Earth Orbit (LEO) satellite networks, which play a pivotal role channel allocation global mobile communication system. Due to nonuniform distribution of users, the existing schemes cannot adapt load differences between beams. On basis resource pool, this paper proposes network architecture LEO that utilizes centralized pool designs combination fixed preallocation dynamic scheduling. The scheduling can allocate or recycle free channels according service...
Accumulating evidence has established the use of mesenchymal stem cells (MSCs) as candidate for immunosuppressive therapy. Experimental studies have suggested that MSCs exert their immunomodulatory effects through induction regulatory T (Tregs) in vitro and vivo. However, interactions between Tregs inflammatory bowel disease (IBD) whether can be used treatment IBD remains to elucidated. In this study, we aimed investigate Tregs. were isolated identified by flow cytometry. The transduced with...
In recent years, the public’s demand for location services has increased significantly. As outdoor positioning matured, indoor become a focus area researchers. Various methods have emerged. Pedestrian dead reckoning (PDR) research hotspot since it does not require infrastructure. An integral equation is used in PDR positioning; thus, errors accumulate during long‐term operation. To eliminate accumulated localisation, this paper proposes localisation system applied to complex scenarios with...
Mesenchymal stem cells (MSCs) inhibit the immune response in vitro and prevent induction of disease certain experimental models. As a result, MSC‑mediated therapy is rapidly growing field research. However, efficacy MSCs treatment inflammatory bowel (IBD) has remained to be determined. In present study, rats with 2,4,6‑trinitrobenzene sulfonic acid (TNBS)‑induced colitis were injected prepared (1x106) into tail vein. Two weeks following intravenous MSC administration, concentration tumor...
Abstract Low earth orbit (LEO) satellite communication networks require huge load capacity and information processing speed to carry global traffic. Inter-satellite links the on-board are key technologies achieve this goal, but new network architecture leads great challenges on routing. This paper designs a hybrid inter-satellite link with same-orbit laser different-orbit microwave increase adopts CPU centralized scheduling improve utilization of computing resources. Then, establishes...
This paper proposes an improved MUSIC algorithm with high-speed parallel optimization for FPGA. Although is a high-performance, classic DOA method, it needs estimation and eigenstructure decomposition of covariance matrix, which time-consuming high computation cost not suitable FPGA implementations. In this paper, the authors present without matrix. offers far lower compared to at expense little performance decrease. With preprocessing focusing on correlation matrices spectral peak search,...
Low Earth orbit (LEO) satellite systems provide terrestrial users with services that are not limited by geographical location. However, the conflict between existing allocation schemes and business variability beams is becoming increasingly prominent. Beam hopping technology allows for a more flexible versatile approach to resource allocation. This paper proposes beam pattern optimization scheme jointly considers interference threshold distance service priority, reducing inter-beam...
The demand for an indoor localization system is increasing, and related research also becoming more universal. Previous works on systems mainly focus the acoustic signals in Line of Sight (LOS) scenario to obtain accurate information, but their effectiveness Nonline (NLOS) remains comparatively untouched. These are usually less efficient as often bring diffraction, refraction, scattering, energy decays, so NLOS environments. So needs adjusting accordingly a complex based identification...
The ultrawideband (UWB) indoor positioning system has poor accuracy and stability in the environment with complex structure, which is affected by non-line-of-sigh (NLOS), multi-path effect, physical measurement other factors. Therefore, this paper proposes a UWB base station (BS) selection method based on time difference of arrival (TDOA) fingerprint. Firstly, TDOA information BS reference point are collected off-line phase. Secondly, on-line phase, improved reversal resonating strength...
With the popularization of smartphones, technology moving human behavior recognition utilizing smartphones has drawn wide attention scholars.
