A neural network-based controller is trained on data collected from connected human-driven vehicles in order to steer a connected automated vehicle on multi-lane roads. The obtained controller is evaluated using model-based simulations and its performance is compared to that of a traditional nonlinear feedback controller. The comparison of the control laws obtained by the two different approaches provides information about the naturalistic nonlinearities in human steering, and this can benefit the controller development of automated vehicles. The effects of time delay emerging from vehicle-to-everything (V2X) communication, computation, and actuation are also highlighted.

The accuracy of industrial robot kinematics parameters directly affects its absolute positioning accuracy. Based on Modify denavit-Hartenberg (Md-H) kinematics theory, a more accurate calibration method for kinematic parameters of industrial robots is proposed in this paper. It takes the kinematics parameters, deceleration ratio and coupling coefficient of the robot as error parameters to establish the error model. The calibration experiment and accuracy verification experiment are designed by laser tracker. After the introduction of the reduction ratio and the coupling coefficient calibration, the absolute positioning error of the robot in all directions has been greatly improved, and the overall average accuracy of the robot is increased by 91.42% compared with the uncalibrated, and is increased by 81.02% compared with the without introducing the deceleration ratio and coupling coefficient.

Unambiguously layer by layer (LBL) assembly of graphene quantum dots (GQds) and dye (GQds/dye) on TiO2 photoanode is the traditional and straightforward approach in the fabrication of graphene quantum dot-sensitized solar cells (QdSSCs). Unfortunately, limited light absorption and low affinity of GQds to TiO2 surface shadow the advantages of LBL and constrains its practical application. Herein, a new strategy of mixture configuration (GQds+dye) was investigated. A distinctive nanoporous honeycomb hexagonal carbon network of GQds was found with fewer defects single crystalline structure, and an average size of 9.87 nm was produced from cellulose. Experimental results demonstrated that LBL exhibited the highest efficiency of 16.76 % under low illumination but a lower efficiency (1.43%) than the mixture method (2.91%) under standard light. The increased Jsc (5.075 mA/cm2) and high charge collection efficiency (0.96) in the mixture sample indicated enhanced electron collection at TiO2. The less -OH groups on TiO2 provides a good surface intact of GQds and N719. In addition to that, the high surface potential (33.47 mV) of the premixed sample restricted the photogenerated electrons to go into a deep state, reducing back electron transfer. Therefore, mixture assembly of co-sensitization is an effective approach for light-harvesting in QdSSC. © 2021, CC BY.

—Nuclear Magnetic resonance (NMr) spectroscopy is an important bio-engineering tool to determine the metabolic concentrations, molecule structures and so on. The data acquisition time, however, is very long in multi-dimensional NMr. To accelerate data acquisition, non-uniformly sampling is an effective way but may encounter severe spectral distortions and unfaithful quantitative measures when the acceleration factor is high. By modelling the acquired signal as the superimposed exponentials, we proposed a virtual peak (VIP) approach to self-adapt the prior spectral information, such as the resonance frequency and peak lineshape, and then feed these information into the reconstruction. The proposed method is further implemented with cloud computing to facilitate online, open, and easy access. results on simulated and experimental data demonstrate that, compared with the low-rank Hankel matrix method, the new approach reconstructs high-fidelity NMr spectra from highly undersampled data and achieves more accurate quantification. The maximum quantitative errors of distances between nuclear pairs and concentrations of metabolites in mixtures have been reduced by 61.1% and 57.7%, respectively. Copyright © 2021, The Authors.

The article describes the synthesis and application of magnesium ferrite nanoparticles (MgFe2O4 NPs) and engineered MgFe2O4 nanocomposites (NCs) by graphene oxide as green and easy separable magnetic adsorbents in removal of Cr(VI) from environmental pollutant. The statistical study of the adsorption process and optimization was accomplished with central composite design method of response surface methodology (rSM) approach. The optimum conditions, predicted by rSM, were achieved at pH, contact time, initial Cr(VI) concentration and adsorbent dosage of 2, 60 min, 40 mg L−1 and 0.15 g, respectively. The removal of Cr(VI) under optimum situations was 97%, and the achieved result in practice was found to be 99%. Pareto analysis suggests the importance relative order of the factors as: pH > concentration of Cr(VI) > time > adsorbent dosage under optimized situations. The engineered nanocomposite was further analyzed for real groundwater samples, and 92% Cr(VI) remediation was resulted. The study is the first study for efficient Cr(VI) remediation from real groundwater sample using novel engineered nanocomposites and has potential to have societal as well as industrial impact in the form of process or product development. © 2018, Springer International Publishing AG, part of Springer Nature.

This study synthesized a novel borate-based glass matrix and evaluated its radiation attenuation capability. Melt-quenching was used to prepare four glass samples with different concentrations from zinc borate glasses. To increase the glass density and the attenuation performance as a result, neodymium oxide (Nd 2 O 3 ) and barium oxide (BaO) gradually substituted boron oxide (B 2 O 3 ) in the glass network. The well-known narrow beam method was used to experimentally attain the linear attenuation coefficient (LAC), and the results were validated through Phy-X software. There was strong theoretical–experimental data agreement, with less than 7 % deviation at all energy levels. The half value layer (HVL) showed a 56 % drop (from 0.097 to 0.043 cm) at 0.059 MeV and an 18 % drop (from 2.537 to 2.084 cm) at 0.662 MeV, and this difference is all due to the increase in Nd 2 O 3 concentration. The radiation protection efficiency (rPE) results indicate an improvement in the glasses' ability to shield photons with increasing Nd 2 O 3 content since it increased from 23.9 % to 28.3 % at 0.662 MeV and from 18.4 % to 21.4 % at 1.173 MeV as a result of increasing the Nd 2 O 3 content from 2 to 8 mol%.

Lignocellulosic biomass is one of the most promising carbon-containing sources, which has vast potential in various fields. Lignin, as the second-highest constituent in lignocellulosic biomass after cellulose, is an underutilized source due to lesser knowledge on its full potential other than using it as a fuel source. The applications of lignin can be further enhanced when the size of lignin is reduced to nanoscale where the surface area and the properties of lignin are improved. Herein, we reviewed the nanoscale lignin, or lignin nanoparticles (LNP) prepared via facile methods, which can lead to the controllable synthesis of LNP at reduced reaction time and chemical consumption. Furthermore, its applications as nanoreinforcer that can enhance the antibacterial, antiradical, UV protectant, emulsion stabilization and catalysis reaction properties of various nanomaterials were discussed. Additionally, the new potential area on the application of catalysis has been highlighted. This review may inspire future research on LNP dedicated to the highlighted research areas. © 2020 Elsevier B.V.

rumen-protected methionine (rPM) is one of the ways to avoid methionine degradation in the rumen and maximize methionine absorption in the intestinal tract of ruminants. This study aims to investigate the effect of rPM added to the diets of ruminants on rumen fermentation and plasma amino acid concentration by in vivo studies using a meta-analysis approach. Twenty-one studies from a total of 15 articles were identified. This consisted of 46 dietary comparisons between control and rPM-added diets. The database was statistically analyzed by using a mixed model method, in which rPM levels were considered as fixed effects, whereas different studies were treated as random effects. The result showed that rPM addition increased linearly propionic acid (C3) and valeric acid concentration, decreased acetic acid (C2) concentration in the rumen (P<0.05), whereas the rPM did not affect total volatile fatty acid, and the C2 and C3 ratio. Ammonia concentration in the rumen decreased with the increase of rPM in the diet. The addition of rPM increased methionine concentration in plasma linearly and increased homocysteine quadratically (P<0.05), whereas the concentration of cysteine, was not affected (P>0.05). In conclusion, rPM addition can modify rumen fermentation and affect the plasma amino acid, which could give benefit ruminant productivity.
