This activity reduces cellular apoptosis and promotes endothelial cell proliferation. Following cellular uptake, Ru@ACEI catalyzes the decomposition of peroxides into water and oxygen, thereby suppressing the NLRP3/Caspase-3/Caspase-9 apoptosis pathway. The consequent improvement in endothelial cell survival helps reverse local hyperinflammation in diabetic wounds.Conclusion: Collectively, these findings demonstrate that the Ru@ACEI nanosystem accelerates diabetic wound healing by mitigating the inflammatory microenvironment and downregulating the expression of pro-inflammatory factors, offering a promising therapeutic strategy for managing chronic diabetic wounds.Keywords: diabetic wound, nanoenzyme, apoptosis, ROS-scavenge, anti-inflammatory microenvironmen
MODELING OF HOPPER DISCHARGE
No full textHoppers are widely used in many engineering processes. The discharging of granular mate- rials from a hopper is a critical topic of industrial importance, and the discharge flow rate from hoppers is the focus of the current work. Many parameters influence the discharge rate including: the hopper outlet width, the angle of the hopper wall, the particle size, and particle friction, and so on. Due to the expensive of examining a large variety of particle types and hopper conditions, computational simulation has been widely studied in an effort to establish an alternative method of determining critical factors impacting hopper flow.
In this thesis, the process of hopper discharge has been simulated by the Discrete Element Method (DEM), which is one of the most popular methods for granular flow simulation. To validate against existing experiments, all conditions were matched as closely as possible to those in the experiment. The particles used in our simulation are spheroids with diameters of 0.77 cm. The angles of the hoppers examined range from 0◦ to 90◦, while the opening sizes vary from 2.9 cm to 4.3 cm. Computationally, the friction coefficient has been adjusted several times and finally is set to 0.5 in the simulation in order to fit the experimental resultsas closely as possible. As a quantitative test of the simulation fidelity we compare the hopper empty time t – which is related to the hopper discharge rate – for these different hopper angles and hopper opening size. As a secondary test of the fit, the survival time τ, the normal force profile, the velocity profile, and the probability of jamming Ps are also computed and compared to existing experimental data from collaborators at Duke University. Ultimately, the goal of the work is to establish the degree of model fidelity necessary in order to closely mimic the experimental results obtained
A Fast Single Image Haze Removal Algorithm Using Color Attenuation Prior
No full textSingle image haze removal has been a challenging problem due to its ill-posed nature. In this paper, we propose a simple but powerful color attenuation prior for haze removal from a single input hazy image. By creating a linear model for modeling the scene depth of the hazy image under this novel prior and learning the parameters of the model with a supervised learning method, the depth information can be well recovered. With the depth map of the hazy image, we can easily estimate the transmission and restore the scene radiance via the atmospheric scattering model, and thus effectively remove the haze from a single image. Experimental results show that the proposed approach outperforms state-of-the-art haze removal algorithms in terms of both efficiency and the dehazing effect
Preparation of High-Precision Dimension Seamless Thick-Walled Pipe by New Cold Rolling Process
No full textIn this study, the cold rolling test on the quenched-tempered hot working die steel pipe with an outer diameter/thickness ratio of no greater than 3 was performed. The evolutionary trend of microstructure was examined by a combination of the microscope, SEM, and EBSD tests. The effect of feed rate on the inner wall roughness of rolled pipe was analyzed by means of white light interference. According to the experimental results, the maximum normal pressure per unit area increases from 1046.7 MPa to 1113.2 MPa with the rise in feed rate from 1 mm/stroke to 6 mm/stroke. Meanwhile, the inner wall roughness of the pipe declines from 0.285 μm to 0.146 μm after rolling. When the feed rate reaches 2 mm/stroke, the maximum normal pressure per unit area is 1058.4 MPa, which causes a significant plastic deformation to the inner wall of the pipe, and the average roughness below 0.2 μm. The microstructure of the pipe is dominated by tempered sorbite whether before or after rolling, and the grain size before rolling is 16.22 μm on average. After cold rolling, the longitudinal structure is deformed along the direction of rolling, in which the average grain size is 24.31 μm. With the increase in deformation work-hardening behavior in the rolling process, the tensile strength improves from 1134 MPa to 1178 MPa, the yield strength increases from 985 MPa to 1125 MPa, and the room temperature impact energy diminishes from 58 J to 52.5 J. After vacuum tempering at 600 °C, it is difficult to eliminate the deformed band microstructure along the rolling direction completely. However, the grain size is reduced after cold rolling, no coarsening occurs, and the impact toughness increases from 52.5 J to 60.5 J. With the recovery of the original microstructure, the mechanical properties are restored to the before rolling level
Contour Moments Based Manipulation of Composite Rigid-Deformable Objects With Finite Time Model Estimation and Shape/Position Control
No full textThe robotic manipulation of composite rigid-deformable objects (i.e., those with mixed nonhomogeneous stiffness properties) is a challenging problem with clear practical applications that, despite the recent progress in the field, it has not been sufficiently studied in the literature. To deal with this issue, in this article, we propose a new visual servoing method that has the capability to manipulate this broad class of objects (which varies from soft to rigid) with the same adaptive strategy. To quantify the object's infinite-dimensional configuration, our new approach computes a compact feedback vector of 2-D contour moments features. A sliding mode control scheme is then designed to simultaneously ensure the finite-time convergence of both the feedback shape error and the model estimation error. The stability of the proposed framework (including the boundedness of all the signals) is rigorously proved with Lyapunov theory. Detailed simulations and experiments are presented to validate the effectiveness of the proposed approach. To the best of the author's knowledge, this is the first time that contour moments along with finite-time control have been used to solve this difficult manipulation problem.Green Open Access added to TU Delft Institutional Repository 'You share, we take care!' - Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Learning & Autonomous Contro
Petal-assisted artificial pollination method enhanced the fruit setting ratios in tea plant (Camellia sinensis)
No full textPollination methods play an important role in developing F1 populations. Our study presents an improved method of petal-assisted artificial pollination in tea plants. The field operation using this method exhibited high efficiency in which more than 500 pistillate flowers per day can be pollinated per capita, and the pollen amount from only one staminate flower was sufficient to pollinate more than five pistillate flowers. Additionally, we surveyed the fruit-setting ratio in three F1 groups, which were established using this method and the influence of rainfall on the fruit-setting ratio. The results indicate that the fruit-setting ratio was superior among the tested F1 population with an average value of 12.90%, and a significant negative correlation was observed between rainfall and fruit-setting ratio. By analyzing the growth states of each F1 population, both a high germination rate and survival rate were observed. Furthermore, the purity for 184 individuals in the F1 population of 'Jiaming 1' × 'Longjing 43' (J × L) were analyzed with 32 selected simple sequence repeats (SSRs). The purposes of this paper are (1) to demonstrate that this method is beneficial to establish high purity F1 populations and (2) to identify the number of SSR markers that are suitable for identification. The parentage analysis detected nine false-hybrid individuals, and the rate of false-hybrid was only 4.89% at 95% confidence, demonstrating that a low false-hybrid rate can be achieved using the method. Furthermore, one to two SSR markers randomly selected from each linkage group or chromosome were recommended as a sufficient quantity for SSR identification
Validation of the plasma-wall self-organization model for density limit in ECRH-assisted start-up of Ohmic discharges on J-TEXT
No full textA recently developed plasma-wall self-organization (PWSO) model predicts a
significantly enhanced density limit, which may be attainable in tokamaks with
ECRH-assisted ohmic startup and sufficiently high initial neutral density.
Experiments have been conducted on J-TEXT to validate such a density limit
scenario based on this model. Experimental results demonstrate that increasing
the pre-filled gas pressure or ECRH power during the startup phase can
effectively enhance plasma purity and raise the density limit at the flat-top.
Despite the dominant carbon fraction in the wall material, some discharges
approach the edge of the density-free regime of the 1D model of PWSO.Comment: 17 pages, 8 figure

Differential and angle-integrated cross sections for the Ca-40(n, alpha)Ar-37 reaction from 4.0 to 6.5 MeV
No full textDifferential cross sections for the (40) Ca(n,) , and reactions are measured at neutron energies of 4.0, 4.5, 5.0, 5.5, 6.0 and 6.5MeV using a double-section gridded ionization chamber and two CaF2 samples. Monoenergetic neutrons were produced through the (2) H(d, n)(3) He reaction with a deuterium gas target. A BF3 neutron counter was utilized to normalize the neutron flux among different measurements. The absolute value of neutron flux was calibrated using a U-238 sample. Angle-integrated cross sections for the (40) Ca(n,) , and reactions are obtained from the integration of the differential data. Model calculations are performed using the TALYS-1.6 code and general agreement is achieved between measurements and calculations. Then the total Ca-40(n,)Ar-37 cross sections are derived from the angle-integrated cross sections combined with the code calculations. Present results are compared with existing measurements and evaluations.Physics, NuclearPhysics, Particles & FieldsSCI(E)[email protected]
