Retracted: State estimation of Takagi‐Sugeno fuzzy system in networked control system with stochastic time delays under unknown attacks
Authors: Aslam Muhammad Shamrooz 
Published: June 2021

AbstractThis article concerns the event‐triggered fuzzy filter design for Takagi‐Sugeno (T‐S) fuzzy systems subject to deception attacks under the stochastic multiple time‐varying delays. A sequence of random variables, which are mutually independent but obey the Bernoulli distribution, is introduced to account for the randomly occurring communication delays. In order to efficiently utilize limited network communication bandwidth resources, the event‐triggering scheme is adopted. A fuzzy filter with the attacked input signal is presented. Moreover, due to communication delays caused by event‐triggering schemes and transmission, the filter adopts non‐synchronous premise variables with the system. Then, by utilizing a model transformation technique, the fuzzy systems are developed. Furthermore, using the piecewise Lyapunov functional method technique, the resulting criterion provides sufficient conditions to ensure that fuzzy systems under deception attacks are stochastically stable with an H∞ performance. Accordingly, the conditions for the co‐design of the fuzzy filter and event‐triggering schemes are given. Finally, numerical simulation with the industrial process provided to verify the proposed event‐triggered design.

Published: June 2021

SummaryThis article presents a new method of fault detection for the two‐stage chemical reactor system. The process can be carried out effectively in the presence of the time‐delay and the unknown inputs and the parameter uncertainties by using the observer‐based method technique. In order to detect the actuator fault, a novel unknown input observer is employed as the residual generator. Multi‐objective optimization techniques and a new performance index are adopted to ensure the robustness and sensitivity of the fault detection observer. Then the problem of fault detection is reduced to the problem of model matching. Furthermore, sufficient conditions are obtained to guarantee that the error system is asymptotically stable with an performance by means of the Lyapunov function technique. Finally, a two‐stage chemical system is borrowed to demonstrate the effectiveness of the obtained methods.

Published: June 2021

AbstractIt is essential to consider chattering alleviation of Sliding Mode Control (SMC) design along with providing the system convergence regardless of initial states utilizing the fixed‐time stability notion. Unknown states and disturbance are two major issues in practical applications, which can be effectively solved by using sliding mode observers. This paper deals with state and disturbance Observers‐based Chattering‐Free Fixed‐time SMC (OCFFSMC) design for a class of high‐order nonlinear systems with unknown disturbance, while only the first state is measured physically. A new form of the combined observer‐controller is designed to provide estimated data of unknown disturbance and unmeasured states in the control law. The designed disturbance observer‐based sliding mode controller is not only capable of estimating unknown disturbance but also capable of alleviating the chattering problem in the control signal. Based on defining a new form of the sliding surface, a new control law is designed to alleviate chattering problem and achieve trajectory tracking in a fixed time independently of initial conditions. The fixed‐time stability proof of the closed‐loop system is obtained using Lyapunov stability theory. The validity of the proposed control scheme, OCFFSMC, is verified by applying two examples and simulating in Simulink/MATLAB.

Published: June 2021

AbstractGeometrically frustrated materials, such as spin ice or kagome lattice, are known to exhibit exotic Hall effect phenomena due to spin chirality. For the first time, Hall effect mechanism is explored in an artificial honeycomb spin ice of Nd–Sn element using Hall probe and polarized neutron reflectivity measurements. In an interesting observation, a strong enhancement in Hall signal at relatively higher temperature of T ∼ 20 K is detected. The effect is attributed to the planar Hall effect due to magnetic moment configuration in spin ice state in low field application. In the antiferromagnetic state of neodymium at low temperature, applied field induced coupling between atomic Nd moments and conduction electrons in underlying lattice causes distinct increment in Hall resistivity at very modest field of H ∼ 0.015 T. The experimental findings suggest the development of a new research vista to study the planar and the field induced Hall effects in artificial spin ice.

Published: June 2021

AbstractHeterogeneous integrations of functionally and chemically distinct materials have been explored to develop promising building blocks for opto‐electronic device applications. Recently, the Van der Waals (vdW)‐assembly of near atom thickness materials has provided excellent opportunities beyond what has been previously been difficult to realize. However, its up‐to‐date demonstrations remain far from achieving the scalability and versatility demanded for practical device applications, that is, the integration is generally demonstrated with intrinsically layered 2D materials of very small lateral dimensions. Herein, the large centimeter‐scale vdW assembly of two different materials with structurally, chemically, and functionally distinct properties, that is, 2D platinum ditelluride (PtTe2) metallic multilayers and non‐layered 3D semiconducting platinum sulfide (PtS) are reported. Both materials are precisely delaminated from their growth wafers inside water and are subsequently integrated on unconventional substrates of desired functionalities. The large‐area vdW‐assembled 2D/3D PtTe2/PtS hetero‐materials on flexible substrates exhibit an excellent photodetection in a spectral range of visible‐to‐near infrared (NIR) wavelength, which is well preserved under severe mechanical deformation. This study paves the way for exploring large‐area flexible opto‐electronic devices solely based on near atom thickness materials.

AbstractIncreasing reports of herbicide‐resistant Palmer amaranth (Amaranthus palmeri S. Watson) pose a serious management concern for Kansas corn (Zea mays L.) producers. The objectives of this study were to evaluate various herbicide programs, including preemergence (PRE) alone, PRE followed by (fb) early postemergence (EPOST), and PRE fb late POST (LPOST) for control of glyphosate‐ and mesotrione‐resistant (GMR) Palmer amaranth in glyphosate‐ and glufosinate‐resistant corn, and their effect on crop injury, yield, and net economic return. Field experiments were conducted in 2018 and 2019 in grower fields with natural infestations of GMR Palmer amaranth near Seward in Stafford County, KS. Preemergence programs, including dicamba + thiencarbazone‐methyl + atrazine and dicamba + [atrazine, bicyclopyrone, mesotrione, S‐metolachlor (ABMS)] or dicamba + ABMS in mixtures with atrazine, mesotrione, S‐metolachlor, and metribuzin provided 89–93% control of GMR Palmer amaranth 3 wk after PRE. Preemergence fb EPOST programs provided 87–96% control of GMR Palmer amaranth at 2 wk after EPOST through 7 wk after LPOST. In comparison, PRE‐only programs provided 62–82% and PRE fb LPOST programs provided 75–86% control. The various herbicide programs resulted in greater corn grain yield ranging from 9,207 to 10,508 kg ha–1 compared with 6,056 kg ha–1 in the nontreated control. The highest net return ($1,300 ha–1) was achieved from dicamba + ABMS + atrazine applied PRE fb EPOST application of ABMS + atrazine. These results suggest that effective PRE fb EPOST herbicide programs consisting of multiple sites of actions are available and provide effective control of GMR Palmer amaranth in glyphosate‐ and glufosinate‐resistant corn.

Published: June 2021

ABSTRACTThe paper presents the initial study of a unique rock‐art site discovered at the northern tip of the Mainland (Grande Terre) of New Caledonia. On the walls of a cliff‐face at the foot of a karst outcrop near Roche Mauprat, people have carved successive layers of geometric and figurative motifs. The fine, detailed engraving style of some human figures is unlike anything identified to date in the rock‐art of New Caledonia, where petroglyph anthropomorphic motifs are very rare. We present the main themes that have been recorded, including geometrics, groups of dancing figures and sets of traditional houses surrounded by trees. Only one European figure was identified, indicating that the main engraving period was probably pre‐contact and pre‐colonial. The paper discusses the relation of this new rock‐art style to other art forms, and especially the well‐studied Kanak engraved bamboo tradition that flourished during the second half of the nineteenth century in New Caledonia.

AbstractAugmented, mixed, and virtual reality applications and content have surged into the higher education arena, thereby allowing institutions to engage in research and development projects to better understand their efficacy within curricula. However, despite the increasing interest, there remains a lack of robust empirical evidence to justify the mainstream acceptance of this approach as an effective and efficient learning tool. In this study, the impact of a mixed reality application focused on long spinal cord sensory and motor pathways is explored in comparison to an existing resource already embedded within an active curriculum (e.g., anatomy drawing screencasts). To assess the changes in learner gain, a quasi‐randomized control trial with a pre‐ and post‐test methodology was used on a cohort of Year 2 medical students, with both the absolute and normalized gain calculated. Similar patterns of learner gain were observed between the two groups; only the multiple‐choice questionnaires were shown to be answered significantly higher with the screencast group. This study adds important empirical data to the emerging field of immersive technologies and the specific impact on short‐term knowledge gain for neuroanatomy teaching, specifically that of long sensory and motor pathways. Despite the limitations of the study, it provides important additional data to the field and intends to support colleagues across the education landscape in making evidence‐informed decisions about the value of including such resources into their curricula.

Published: June 2021

AbstractThis paper aims at designing, in the discrete‐time setting and using sliding mode techniques, some controllers ensuring the tracking of desired references of lateral and yaw velocities for a ground vehicle with active front steering and rear torque vectoring actuators. The vehicle is described by an enhanced discrete‐time model, recently presented in the literature. These three controllers have been designed considering the modified equivalent control method for perturbation attenuation, the discrete‐time‐like super‐twisting algorithm, and the discrete‐time reaching law. They have been tested with a simulation study using CarSim, where the three controllers are compared under parametric variations, external perturbations, and different sampling periods.

Published: June 2021

AbstractCalcium carbonate (CaCO3), a mineral commonly found in the Earth's crust, is mainly in the forms of calcite and aragonite. Calcite has the most stable type of thermodynamics at room temperature and ambient pressure. It has wide band gap structure and is of great interest for a wide‐range technical and industrial applications due to its physical properties and suitability. In this study, a new method based on the long short‐term memory (LSTM) model of deep learning is proposed to classify the thermoluminescence properties such as fading, cycle of measurement, heating rate, and dose–response of CaCO3. Therefore the thermoluminescence properties of calcite was investigated as a suitable band structure and its coherent data were used to classify the features using a deep learning LSTM model. Experiments were carried out on a dataset consisting of four classes. The accuracy, precision, and sensitivity values of the proposed model obtained were 98.34, 97.90, and 98.56%, respectively. The classification process of the results obtained from the designed model showed good performance.

Published: June 2021

AbstractAmid rising environmental concerns, Industry 4.0 and blockchain technology (BCT) are transforming circular economy (CE) practices and prevailing business models. Recognize the same; this study examines the role of blockchain technology in circular CE practices and their impact on eco‐environmental performance, which influences organizational performance. The study collects data from 404 enterprises located in Chinese and Pakistani territories, involved in cross‐border supply chain operations. Both countries' sample has great relevance due to the China Pakistan Economic Corridor (CPEC), which possesses several positive fallouts in terms of technology spillovers across firms. Using the partial least squares structural equation modeling (PLS‐SEM) modeling framework, this study provides three key findings. First, BCT significantly improves the circular economy practices (circular procurement, circular design, recycling, and remanufacturing). Second, CE practices help improve firms' environmental performance and stimulate their financial performance. Third, higher eco‐environmental performance significantly boosts organizational performance. This study sets out the foundations for participating countries/firms that simultaneously achieve financial and sustainable goals by integrating blockchain technology in circular economy practices.

Published: June 2021

AbstractBackgroundPneumocystis jirovecii pneumonia (PJP) is a life‐threatening infection occurring in patients receiving bendamustine. The poorly defined incidence, particularly when utilizing polymerase chain reaction (PCR)‐based diagnostic techniques, precipitates unclear prophylaxis recommendations. Our objective was to determine the cumulative incidence of PJP diagnosed by single copy target, non‐nested PCR in patients receiving bendamustine.MethodsPatients were evaluated for PJP from initiation of bendamustine through 9 months after the last administration. The cumulative incidence of PJP was estimated using the Aalen–Johansen method. Cox proportional hazard models were used to demonstrate the strength of association between the independent variables and PJP risk.ResultsThis single‐center, retrospective cohort included 486 adult patients receiving bendamustine from 1 January 2006 through 1 August 2019. Most patients received bendamustine‐based combination therapy (n = 461, 94.9%), and 225 (46.3%) patients completed six cycles. Rituximab was the most common concurrent agent (n = 431, 88.7%). The cumulative incidence of PJP was 1.7% (95% CI 0.8%–3.3%, at maximum follow‐up of 2.5 years), after the start of bendamustine (n = 8 PJP events overall). Prior stem cell transplant, prior chemotherapy within 1 year of bendamustine, and lack of concurrent chemotherapy were associated with the development of PJP in univariate analyses. Anti‐Pneumocystis prophylaxis was not significantly associated with a reduction in PJP compared to no prophylaxis (HR 0.37, 95% CI (0.05, 3.04), p = 0.36).ConclusionsOur incidence of PJP below 3.5%, the conventional threshold for prophylaxis implementation, indicates routine anti‐Pneumocystis prophylaxis may not be necessary in this population. Factors indicating a high‐risk population for targeted prophylaxis require further investigation.

Published: June 2021

AbstractThis paper discusses a novel approach for exploiting emotions and situation‐aware software adaptation methods for individualizing some of the touch points of the digital customer journey and thereby optimizing customer experience and effectiveness of e‐commerce applications. Our approach uses emotion recognition, eye‐tracking, and other individual tracking methods as well as customer personas for adapting interactive web applications by accessing a flexible adaptation framework at runtime. The framework allows for individualization at runtime by applying situation‐aware adaptations. Two experimental customer studies were carried out in the e‐commerce domain in order to provide a basis for exploitable emotion‐ and persona‐related situational changes. The results of the studies were used to demonstrate the potential of our situation analytic adaptation approach with examples from a commercial beauty‐products e‐business portal.

AbstractThree new monoterpenoids, named eucomylides A−C (1–3), along with six known compounds (4–9) were isolated from the staminate flowers of Eucommia ulmoides Oliver. The structures were elucidated by extensive analyses of spectroscopic methods, and their absolute configurations were established by time‐dependent density functional theory electronic circular dichroism (TDDFT ECD) calculation. All the compounds along with previously isolated components (10–14) were tested for their anti‐inflammatory effects. Two iridoid glycosides (11 and 12) and a flavonoid glycoside (14) showed potent suppressive effects on nitric oxide (NO) production in RAW 264.7 cells, with IC50 values ranging from 17.11 to 22.26 μM.

Published: June 2021

AbstractAcute ischemic stroke is a feared complication during cardiovascular procedures associated with high morbidity and mortality if not immediately recognized and treated. We conducted a review of cases at our center where patients experienced an acute, procedure‐related ischemic stroke and underwent immediate endovascular stroke treatment by the interventional cardiologists trained in acute endovascular stroke intervention. Baseline demographics, procedural and follow‐up data were collected. Three patients were identified in whom the percutaneous procedure (peripheral arterial intervention, transapical NeoChord [NeoChord Inc, Minnesota, USA] implantation and transcatheter aortic valve implantation, respectively) was complicated by an acute embolic ischemic stroke. In all cases, cerebral vessel re‐canalization was technically successful with thrombolysis in cerebral infarction (TICI) IIB/III flow. Follow‐up computed tomography scans showed no infarct demarcation, oedema or intracranial hemorrhage. One patient survived with no neurological symptoms at 6‐month follow‐up whereas the two other patients died of unrelated intensive care complications and decompensated heart failure. We conclude that endovascular stroke treatment during cardiovascular interventions can be performed by interventional cardiologists with appropriate training. It offers the unique opportunity to treat cerebral embolization in a time‐efficient manner, potentially improving morbidity and mortality of affected patients.
