Robust model predictive tracking control for the wheeled mobile robot with boundary uncertain based on linear matrix inequalities
Authors: Gao Xing , Su Xin , An Aimin , Zhang Haochen
Published: March 2023

In this study, a robust model predictive controller is designed for the trajectory tracking problem of non‐holonomic constrained wheeled mobile robot based on an elliptic invariant set approach. The controller is based on a time‐varying error model of robot kinematics and uses linear matrix inequalities to solve the robust tracking problem taking uncertainties into account. The uncertainties are modelled by linear fractional transform form to contain both parameter perturbations and external disturbances. The control strategy consists of a feedforward term that drives the centre of the ellipse to the reference point and a feedback term that converges the uncertain system state error to the equilibrium point. The strategy stabilises the nominal system and ensures that all states of the uncertain system remain within the ellipsoid at each step, thus achieving robust stability of the uncertain system. Finally, the robustness of the algorithm and its resistance to disturbances are verified by simulation and experiment.
Controller parameter tuning for gain‐scheduled vehicle yaw‐rate control: Virtual reference feedback tuning approach
Authors: Yahagi Shuichi , Suzuki Motoya
Published: March 2023

In control theory, a controller parameter‐tuning method called virtual reference feedback tuning (VRFT) is proposed. VRFT can tune a feedback controller using single experimental data. If VRFT can be applied to a vehicle, the yaw‐rate controller can be adequately tuned without the need for a vehicle model. Therefore, this study expands the results of VRFT to realize the desired yaw‐rate control of autonomous vehicles. The key point of the proposed method is to realize the auto‐tuning of the gain‐schedule proportional–integral (PI) controller based on the vehicle velocity. In this study, the validity of the proposed method using a vehicle dynamics block set is verified.
Distributed fault‐tolerant control for high‐speed trains based on adaptive terminal sliding mode control
Authors: Guo Youxing , Sun Pengfei , Wang Qingyuan , Chen Mo , Wang Xiaowen , Feng Xiaoyun
Published: March 2023

Here, a distributed multi‐body dynamics model of high‐speed train (HST) with actuator faults is established. Based on this detail model, a non‐singular terminal sliding mode control method is designed for HST distributed fault‐tolerant control, and the stability of the proposed controller is proved strictly. Considering the high uncertainty of the distributed dynamics model, a radial basis function neural network is introduced to approximate the system uncertainties. Then a universal fuzzy system is proposed to eliminate the chattering problem from sliding mode controller in train control, which further improves the comfort of the train. Finally, numerical simulations are carried out using data from CRH380B train, and model reference adaptive control (MRAC) and adaptive sliding mode control are also tested under the same condition for performance comparison. The results confirm the effectiveness of the proposed controller. Compared with existing MRAC, the root mean square of the speed and position tracking error are reduced by 23.4% and 52%, respectively.

The drilling shut in affects the production year by year. The formation pressure decreases greatly during the drilling shut in process, which affects the development situation. In order to reduce the impact of drilling shut in on production, control the decline of formation pressure, and explore the management methods and methods of drilling shut in. In order to reduce the impact of drilling shut in on production and control the decline of formation pressure, we explore the management methods of drilling shut in.
Analysis of development status and adjustment method of a block
Authors: Han Hongzhi
Published: March 2023

Since a certain block was put into development, it has always put improving the injection production relationship and improving the ultimate recovery factor in the first place. Through a series of infill adjustment, supplement and extended drilling, the injection production relationship of single sand body has been gradually improved. In high water cut period, the remaining oil distribution has been quantified through joint multidisciplinary research, and the fluid production structure has been adjusted by combining the oil well injection, hole filling, drilling and other measures, Hard and stable production in high water cut stage is realized. However, due to the small scale of sand body development and fault development, the contradiction between single sand body injection and production is still prominent. From the perspective of development effect of Gaotaizi old area, compared with Xingnan development area, the degree of recovery at the same water bearing stage is obviously low, and the development effect is poor. At present, the comprehensive water cut has reached 92.77%, and the recovery percentage is only 28.05%. The research shall be based on the results of fine reservoir description, guided by the results of multidisciplinary research, and focus on the comprehensive analysis and sorting of the injection production relationship of single sand body through the re understanding of geology, so as to find the adjustment potential of supplement and injection conversion. Through the adjustment of the injection production system, increase the water injection well points, expand the swept volume, improve the degree of water drive control, so as to increase the formation pressure and improve the development effect of the block.

Published: March 2023

A continuous adductor canal block (cACB) for pain control in total knee arthroplasty (TKA) is always performed by an anesthesiologist. A surgeon-performed cACB during surgery is somewhat questionable in terms of feasibility, reproducibility, and efficacy. This study was divided into two phases. In Phase 1 study, an experimental dissection of 16 cadaveric knees to expose the saphenous nerve and related muscles around the adductor canal was conducted. The extent of dye after injection via a catheter inserted into the adductor canal at the time of TKA was evaluated. In Phase II, a randomized controlled trial study comparing clinical outcomes between surgeon-performed (Group 1) and anesthesiologist-performed cACB (Group 2) during TKA in 63 patients was evaluated. The visual analogue scale (VAS) at rest and during movement at several time points and functional outcomes during hospitalization were compared. The Phase I study demonstrated surgeon-performed cACB during surgery feasible and reproducible with consistent dye extension into the adductor canal after injection via a catheter. In the Phase II study, 29 patients of Group 1 and 30 patients of Group 2 completed the evaluation with no differences in baseline parameters. The VAS during movement at 24 and 36 hours, quadriceps strength, time up and go test, and knee motion at different time points, and total morphine consumption showed no differences between both groups. There were no procedure-related complications. The surgeon-performed cACB during surgery was feasible and reproducible with similar VAS scores and functional outcomes during hospitalization to anesthesiologist cACB. Level of evidence is Level I, prospective randomized trial.

Published: March 2023

Background Research is needed to identify how clinical decision support (CDS) systems can support communication about and engagement with tobacco use treatment in pediatric settings for parents who smoke. We developed a CDS system that identifies parents who smoke, delivers motivational messages to start treatment, connects parents to treatment, and supports pediatrician–parent discussion.

Objective The objective of this study is to assess the performance of this system in clinical practice, including receipt of motivational messages and tobacco use treatment acceptance rates.

Methods The system was evaluated at one large pediatric practice through a single-arm pilot study from June to November 2021. We collected data on the performance of the CDS system for all parents. Additionally, we surveyed a sample of parents immediately after the clinical encounter who used the system and reported smoking. Measures were: (1) the parent remembered the motivational message, (2) the pediatrician reinforced the message, and (3) treatment acceptance rates. Treatments included nicotine replacement therapy, quitline referral (phone counseling), and/or SmokefreeTXT referral (text message counseling). We described survey response rates overall and with 95% confidence intervals (CIs).

Results During the entire study period, 8,488 parents completed use of the CDS: 9.3% (n = 786) reported smoking and 48.2% (n = 379) accepted at least one treatment. A total of 102 parents who smoke who used the system were approached to survey 100 parents (98% response rate). Most parents self-identified as female (84%), aged 25 to 34 years (56%), and Black/African American (94%), and had children with Medicaid insurance (95%). Of parents surveyed, 54% accepted at least one treatment option. Most parents recalled the motivational message (79%; 95% CI: 71–87%), and 31% (95% CI: 19–44%) reported that the pediatrician reinforced the motivational message.

Conclusion A CDS system to support parental tobacco use treatment in pediatric primary care enhanced motivational messaging about smoking cessation and evidence-based treatment initiation.

Published: March 2023

Background The initial clinical status after aneurysm rupture, whether primary or secondary, determines the final outcome. The most common cause of patient deterioration is a high Hunt and Hess (HH) score, which correlates closely with a high mortality rate. Poor-grade aneurysmal subarachnoid hemorrhage (SAH) is determined as an HH score 4 or 5. The aim of this study was to evaluate the clinical characteristics of poor graded aneurysmal SAH at our institution.

Patients and Methods During the 5-year period, 415 patients with intracranial aneurysm were admitted to our institution. Patients with poor-grade aneurysmal SAH accounted 31.08% (n = 132) of the total number of ruptured aneurysms. Interventional treatment was predominantly in the form of surgery, whereas conservative treatment included medication and external ventricular drainage. Final outcome was assessed with a modified Rankin score (mRs). Statistical analysis was performed using SPSS version 23.0 with a significance level set to 5% (α = 0.05).

Results The majority of patients (57.6%) were in the age range from 51 to 69 years. Twenty-five patients (18.9%) had an HH score of 4, whereas 107 patients (81.1%) had an HH score of 5. Depending on the location, the majority of patients (n = 43) had an aneurysm on the medial cerebral artery (MCA). The final aneurysm occlusion was performed in 71 patients, of whom 94.36% were treated surgically. A positive outcome (mRs 0–4) was found in 49.25% of patients who underwent primarily surgical, treatment with a mortality of 42.3%. Although the outcome was better in patients with an HH score 4, both groups benefited from surgical treatment.

Conclusion Poor-grade aneurismal SAH is a condition of the middle and older age, with most patients with an HH 5 score and deep comatose state. There was better outcome in patients with an HH score of 4 compared to an HH score of 5 and both groups benefited from surgical treatment, which resulted in a positive outcome in almost 50% of surgically treated patients.
Cathodoluminescence studies of point defects in aluminum nitride
Authors: Lu Zhengqian , Wang Yuning , Wang Chuang , Wang Fang , Xu Ke , Liu Yuhuai
Published: March 2023

There is near-ultraviolet and yellow light absorption in AlN crystal. The defect of this absorption hampers the transmittance of ultraviolet light, which, in turn, limits the application of aluminum nitride substrate in deep ultraviolet electronic devices. In this paper, the sources of absorption defects are determined through the first principle simulation method and the cathodoluminescence test of four samples with different growth modes on two substrates. The peak positions of the two AlN grown by metal–organic chemical vapor deposition were observed at 370 and 480 nm; two AlN samples grown by hydride vapor phase epitaxy only observed luminescence near 370 nm. Through the characterization of sample components by x-ray photoelectron spectroscopy, it is speculated that O impurity component and Al vacancy in AlN crystal form donor–acceptor pairs, which are the source of 370 nm luminescence; with the increase in O concentration, a composite defect with Al vacancy is formed, which is the source of 480 nm luminescence. This is very important for further research on eliminating impurity absorption in an AlN epitaxial layer.

Published: March 2023

Magnetic interfaces and the phenomena arising from them drive both the design of modern spintronics and fundamental research. Recently, it was revealed that through designing magnetic frustration in configurationally complex entropy stabilized oxides, exchange bias can occur in structurally single crystal films. This eliminates the need for complex heterostructures and nanocomposites in the design and control of magnetic response phenomena. In this work, we demonstrate through hole doping of a high entropy perovskite oxide that tuning of magnetic responses can be achieved. With detailed magnetometry, we show magnetic coupling exhibiting a variety of magnetic responses including exchange bias and antiferromagnetic spin reversal in the entropy stabilized ABO3 perovskite oxide La1−xSrx(Cr0.2Mn0.2Fe0.2Co0.2Ni0.2)O3 family. We find that manipulation of the A-site charge state can be used to balance magnetic phase compositions and coupling responses. This allows for the creation of highly tunable exchange bias responses. In the low Sr doping regime, a spin frustrated region arising at the antiferromagnetic phase boundary is shown to directly couple to the antiferromagnetic moments of the film and emerges as the dominant mechanism, leading to a vertical shift of magnetization loops in response to field biasing. At higher concentrations, direct coupling of antiferromagnetic and ferromagnetic regions is observed. This tunability of magnetic coupling is discussed within the context of these three competing magnetic phases, revealing critical features in designing exchange bias through exploiting spin frustration and disorder in high entropy oxides.
Partial replacement of maize with cassava root–moringa leaf and vegetable oil concentrates in broiler finisher diets
Authors: Havea Tigris , Diarra Siaka , Pym Robert A. E.
Published: March 2023

Context Roots and leaves have potential as feed ingredients for poultry, but antinutritional factors (ANFs), high fibre and low energy may limit their efficient utilisation. There is need to improve processing methods and diet formulation for maximum utilisation of these readily available resources and reduce feed cost. Aim To investigate the replacement of maize with cassava root, moringa leaf meal and vegetable oil blend in finisher broiler diets. Methods In total, 160 male broiler chickens aged 30 days were weighed and allotted randomly to 20 deep litter pens containing eight birds of similar individual weight (1500 g ± 16.11). Four broiler finisher iso-energetic and iso-nitrogenous diets were formulated for the experiment. Diet 1 was based on maize and in Diets 2, 3 and 4, 15%, 30% and 45% of maize was replaced respectively, by a concentrate of cassava root meal, moringa leaf meal and vegetable oil combination (CMOC). Each diet was given to five pens in a completely randomised design for a period of 12 days. Key results There were no significant differences in the growth parameters of birds among treatments. Except for drumsticks of birds on the 30% CMOC diet, there were no significant effects of diet on carcass components or digestive organ weights (P > 0.05). Gizzard pH was higher in the control birds than in the test groups. Feed cost per kilogram of carcass weight was significantly (P < 0.05) lower with the dietary inclusion of CMOC. Conclusion Replacing up to 30% of the maize with CMOC is beneficial and replacement up to 45% is not detrimental. However, the economic benefits of maize replacement with CMOC need to be re-evaluated with ingredient costings less affected by the present COVID-19 pandemic. Implications Maximum utilisation of cassava root and moringa leaf meal in the diet will reduce cost and improve income of small- to medium-holder broiler producers.
Digital agriculture in Europe and in France: which organisations can boost adoption levels?
Authors: Bellon-Maurel Véronique , Piot-Lepetit Isabelle , Lachia Nina , Tisseyre Bruno
Published: March 2023

This paper presents the way the digital transformation of the agricultural sector is implemented in Europe and in France. It describes the main European and national strategies, the structure of research and innovation initiatives, and the investment in capacity building to foster innovation, adoption and use. More specifically, the French research and innovation ecosystem on digital agriculture is described. The actors involved come from different organisations, such as research and higher educational institutes, government agencies, agricultural technology (AgTech) companies, farmer unions etc., and work together by means of associations (e.g. Robagri), networks (e.g. RMT Naexus, DigiFermes, Fermes Leader), or living labs (e.g. Occitanum) on both digital technology assessment and co-design. Additionally, support is devoted to capacity building (e.g. Le Mas numérique, Mobilab) and a better understanding of the drivers of adoption and use of digital technologies (e.g. FrOCDA). Among these various organisations, #DigitAg, the Digital Agriculture Convergence Lab, has been created to foster interdisciplinary research on digital agriculture. All these initiatives aim to use digital technologies to support the European Green Deal, Farm-to-Fork and Biodiversity strategies as well as the French orientation towards more agroecological practices for safer and more sustainable food systems. Even though this organisational ecosystem is developing fast, the objective of encouraging the coevolution of both digital and green transformations is not without challenges that still need to be overcome, either through new research, innovations, initiatives or collaborations between the actors involved.
Our shared global responsibility: Safeguarding crop diversity for future generations
Authors: Dempewolf Hannes , Krishnan Sarada , Guarino Luigi
Published: March 2023

The resilience and sustainability of food systems depend on crop diversity. It is used by breeders to produce new and better varieties, and by farmers to respond to new challenges or demands and to spread risk. However, crop diversity can only be used if it has been conserved, can be identified as the solution for a given problem, and is available. As the ways in which crop diversity is used in research and breeding change and expand, the global conservation system for crop diversity must keep pace; it must provide not only the biological materials themselves, but also the relevant information presented in a comprehensive and coherent way—all while ensuring equitable access and benefit sharing. Here we explore the evolving priorities for global efforts to safeguard and make available the diversity of the world's crops through ex situ genetic resource collections. We suggest that collections held by academic institutions and other holders that are not standard gene banks should be better integrated in global efforts and decision-making to conserve genetic resources. We conclude with key actions that we suggest should be taken to ensure that crop diversity collections of all types are able to fulfill their role to foster more diverse, equitable, resilient, and sustainable food systems globally.

Published: March 2023

Two-dimensional (2D) ferromagnetic crystals with fascinating optical and electrical properties are crucial for nanotechnology and have a wide variety of applications in spintronics. However, low Curie temperatures of most 2D ferromagnetic crystals seriously hinder their practical applications, thus searching for intrinsic room-temperature 2D ferromagnetic crystals is of great importance for development of information technology. Fortunately, progresses have been achieved in the last few years. Here we review recent advances in the field of intrinsic room-temperature 2D ferromagnetic crystals and introduce their applications in spintronic devices based on van der Waals heterostructures. Finally, the remaining challenge and future perspective on the development direction of intrinsic room-temperature 2D ferromagnetic crystals for 2D spintronics and van der Waals spintronics are briefly summarized.
Study of the intermediate mass ratio black hole binary merger up to 1000:1 with numerical relativity
Authors: Lousto Carlos O , Healy James
Published: March 2023

We explicitly demonstrate that current numerical relativity techniques are able to accurately evolve black hole binaries with mass ratios of the order of 1000:1. This proof of principle is relevant for future third generation gravitational wave detectors and space mission LISA, as by purely numerical methods we would be able to accurately compute gravitational waves from the last stages of black hole mergers, as directly predicted by general relativity. We perform a sequence of simulations in the intermediate to small mass ratio regime,

. We compare these headon full numerical evolutions with the corresponding semianalytic point particle perturbative results finding an impressive agreement for the total gravitational radiated energy and linear momentum as well as for the waveform spectra. We display numerical convergence of the results and identify the minimal numerical resolutions required to accurately solve for these very low amplitude gravitational waves. This work represents a first step towards the considerable challenge of applying numerical-relativity waveforms to interpreting gravitational-wave observations by LISA and next-generation ground-based gravitational-wave detectors.

Published: March 2023

A method is described where 3D electronic devices are fabricated using a hybrid printing approach which combines several steps: Top illumination stereolithography; laser induced forward transfer (LIFT) printing of conductive materials; placement of active and passive components and their electrical interconnection by a non-contact, metal LIFT process. By applying this approach, free-form 3D functional electronic structures could be manufactured by a single hybrid tool. The adhesion of LIFT printed metal droplets onto various organic substrates of interest for device fabrication was investigated. The results suggest two possible approaches for improved adhesion by either printing at elevated surface temperature or surface roughening by laser pre-treatment. The resulting track resistivities were found to be in the range of ×5–10 higher than bulk copper resistivity. We present several exemplary printed devices with different complexities and functionalities as demonstrators of the proposed hybrid technology.
Novel Fiducial Fiber Scanning Measurement Method Based on a Polar Coordinate System for LAMOST
Authors: Zhang Zhen , Chen Guifeng , Liu Wenqi , Zhu Mengjie , Wang Menghao , Gu Yonggang , Zhai Chao
Published: March 2023

The multiobject fiber-fed spectrograph is the core scientific instrument for large-scale spectroscopic surveys. For closed-loop control of fiber positioning, fiber metrology systems are implemented in numerous fiber-fed spectrographs. The position accuracy of the fiducial fiber in the focal plate directly affects the performance of the fiber metrology system. However, there are currently no suitable methods and devices for measuring the fiducial fibers with high accuracy in the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST). To solve this problem, this study proposed a novel online scanning measurement method for fiducial fibers in which a scanning camera was set up in front of the focal plate, and the rotation and translation movements of the focal plate were combined to set a polar coordinate measurement system. First, the pole and polar axis of the polar coordinate frame were determined, and the compensation values of the polar radius and angle of the polar coordinate of the fiducial fibers were solved in the field of view of the scanning camera. A prototype measurement platform was set up to verify the feasibility and scientific validity of the method. Experiment results show that the polar radius accuracy of the proposed method met the measurement requirements. The X–Y measurement accuracy can be further improved when a higher-precision rotary stage is adopted. Thus, the difficulties in online accurate measurement for fiducial fibers can be tackled by the proposed method with good operability in LAMOST.
Production and decay of polarized hyperon-antihyperon pairs*

Published: March 2023

Polarized hyperon-antihyperon pairs shed light on various unresolved puzzles in contemporary physics: How the strong interaction confines quarks into hadrons, how accurately the Standard Model describes microcosmos and even why our universe consists of so much more matter than antimatter. Thanks to their weak, parity violating decays, hyperons reveal their spin properties. This can be exploited e.g. the decomposition of the electromagnetic structure of hyperons, precision tests of flavour symmetry and searches for CP violation. At the BESIII experiment at BEPC-II, Beijing, China, hyperon-antihyperon pairs can be produced in abundance. Recently collected large data samples have triggered the development of new methods that provide unprecedented precision and a plethora of new results have emerged. When applied at future high-intensity facilities like PANDA and STCF, precision physics will be taken to a new level which can contribute to the solution to the aforementioned puzzles.
Examination of machine learning for assessing physical effects: Learning the relativistic continuum mass table with kernel ridge regression*
Authors: Du Xiao-Kai , Guo Peng , Wu Xin-Hui , Zhang Shuang-Quan
Published: March 2023

The kernel ridge regression (KRR) method and its extension with odd-even effects (KRRoe) are used to learn the nuclear mass table obtained by the relativistic continuum Hartree-Bogoliubov theory. With respect to the binding energies of 9035 nuclei, the KRR method achieves a root-mean-square deviation of 0.96 MeV, and the KRRoe method remarkably reduces the deviation to 0.17 MeV. By investigating the shell effects, one-nucleon and two-nucleon separation energies, odd-even mass differences, and empirical proton-neutron interactions extracted from the learned binding energies, the ability of the machine learning tool to grasp the known physics is discussed. It is found that the shell effects, evolutions of nucleon separation energies, and empirical proton-neutron interactions are well reproduced by both the KRR and KRRoe methods, although the odd-even mass differences can only be reproduced by the KRRoe method.

In this work, we study the doubly charmed dibaryon states with the

(

) configuration. The mass spectra of doubly charmed dibaryon states are obtained systematically within the chromomagnetic interaction model. In addition to the mass spectrum analysis, we illustrate their two-body strong decay behaviours. Our results suggest that there may be narrow states or even stable states that cannot decay through the strong interaction. We hope that our results will provide valuable information for further experimental searches for doubly charmed dibaryon states.
Microhardness and tensile strength of electrochemically synthesized nickel-cobalt binary alloy sheets exfoliated from a dumbbell-shaped titanium cathode

Published: March 2023

Nanocrystalline nickel–cobalt (Ni–Co) binary alloy sheets were fabricated through electroforming in an acidic aqueous bath using exfoliation from a metallic titanium cathode. Cobalt content in Ni–Co alloy sheets ranged from 28.8 at% to 72.0 at% depending on experimental parameters, such as cathodic overpotential and bath composition. The surface roughness (R
a) of the electroformed alloy sheets significantly decreased down to 1.5 μm as saccharin sodium dihydrate was added as an additive to the acidic aqueous solution bath. X-ray diffraction profiles and transmission electron microscopy images indicated that the electroformed Ni–Co alloy sheets have a nanocrystalline structure (grain size ≈ 30 nm). The lattice constant of the electroformed Ni–Co alloy sheets increased with an increase in cobalt content (i.e. solute atom concentration). The mechanical properties were significantly improved because of the synergistic effects of crystal grain refinement and solid solution strengthening. The microhardness and tensile strength of the electroformed Ni–Co alloy sheets reached 609 kgf mm−2 and 1757 MPa (X
Co = 49.9 at%), respectively. The tensile strength of the electroformed Ni–Co alloy sheets in this study significantly exceeded that of solidified Ni–Co alloys (approximately 370 MPa). Therefore, this study offers a technique to enhance the mechanical properties of electroformed Ni–Co alloy sheets.
