Process monitoring and fault diagnosis method combining bagging DPCA‐ICA with moving window Kolmogorov–Smirnov test
Authors: Zhou Siyuan , Zhou Xiaomin , Liu Hongfei 
Published: February 2024

AbstractProcess monitoring and fault diagnosis systems are essential for ensuring the quality and safety of industrial processes. Real industrial process data always has dynamic features, autocorrelation features, and non‐Gaussian distributions, making many multivariate statistical process monitoring (MSPM) methods, such as principal component analysis (PCA), not work well. To solve the problem, a new process monitoring method (named DPCA‐ICA‐moving window Kolmogorov–Smirnov test [MWKS]) is proposed in the paper, which is a combination of DPCA and independent component analysis (ICA) with adaptive weight parameters and introduces a moving window technique and two‐sample K‐S test to obtain the K‐S distance of the commonly used Hotelling's and square predictive error as new monitoring parameters. Experimental results on the Tennessee Eastman chemical process demonstrate the effectiveness and accuracy of the proposed method, which shows it has better performance than existing commonly used methods. The average fault detection rate (FDR) is 93.131%, while the average false alarm rate (FAR) of the proposed method is only 0.1%.

Published: February 2024

Comprehensive SummaryActin filaments play important physiological functions, which have become potential targets of antitumor drugs. Using chemicals to intervene their polymerization‐depolymerization dynamics would generate new strategies for designing antitumor drugs. In this report, an artificial water channel appending acetazolamide moiety, a ligand that can selectively bind to carbonic anhydrase IX, has been prepared. We demonstrated that this conjugate can target colorectal cancer cells overexpressing carbonic anhydrase IX and trigger the depolymerization of actin filaments of the cancer cells by selectively mediating water transmembrane transport. Moreover, the conjugate‐promoted actin depolymerization led to tumor cell apoptosis and its high antitumor activity in vitro and in vivo against colorectal cancer. The method described herein represents a new and general strategy for designing antitumor drugs by using artificial channel‐mediated selective water transport to promote actin depolymerization.

Authors: Conti Ylli , Chiang Naihao , Scarabelli Leonardo 
Published: February 2024

AbstractColloidal metasurfaces are emerging as promising candidates for the development of functional chemical metamaterials, combining the undisputed control over crystallography and surface chemistry achieved by synthetic nanochemistry with the scalability and versatility of colloidal self‐assembly strategies. In light of recent reports of colloidal plasmonic materials displaying high‐performing optical cavities, this Minireview discusses the use of this type of metamaterials in the specific context of non‐linear optical phenomena and non‐linear molecular spectroscopies. Our attention is focused on the opportunities and advantages that colloidal nanoparticles and self‐assembled plasmonic metasurfaces can bring to the table compared to more traditional nanofabrication strategies. Specifically, we believe that future work in this direction will express the full potential of non‐linear molecular spectroscopies to explore the chemical space, with a deeper understanding of plasmon‐molecule dynamics, plasmon‐mediated processes, and surface‐enhanced chemistry.

Published: February 2024

AbstractWith the popularity and development of electronic devices, the demand for lithium batteries is increasing, which also puts high demands on the energy density, cycle life and safety of lithium batteries. Gel electrolytes achieve both of these requirements by curing the electrolytes to reduce the interfacial side reactions of lithium metal batteries. The ionic conductivity of the gel electrolytes prepared by in situ curing reach 8.0×10−4 S cm−1, and the ionic mobility number is 0.53. Meanwhile, the gel electrolytes maintain a stable electrochemical window of 1.0–5.0 V. Benefited with the interfacial regulation of PEGDA gel electrolytes, the gel lithium metal batteries show better cycling stability, and achieved 97 % capacity retention after 200 cycles (0.2 C) with a lower increasing rate of impedance.
Uncovering Energetic Positions of Surface Trap States in α‐Fe2O3 Treated with Cobalt Phosphate (Co−Pi) Using Charge Carrier‐Selective Heterodyne Transient Grating Technique
Authors: Hyun Kim Young , Gyeong Bae Yu , Yong Sohn Woon 
Published: February 2024

AbstractNear‐field heterodyne transient grating (NF‐HD‐TG) responses of hematite (α‐Fe2O3) treated with cobalt phosphate (Co−Pi) were measured with the burn lasers inducing the depletion of the response by the removal of the trapped charge carriers in the target state, which is called charge carrier‐selective heterodyne transient grating (CS‐HD‐TG) spectroscopic technique. We found that two distinct trap states co‐existed in Co−Pi loaded on the surface of α‐Fe2O3. One of them named r‐SS2, of which potential was similar to that of r‐SS1 in the surface of α‐Fe2O3, acted as a recombination centre but could increase the lifetime of the trapped holes by the charge separation. We also revealed that the energetic position of the other (i‐SS2), which has been regarded as the intermediate state for oxygen evolution reaction with low overpotential, was higher than that of i‐SS1 in α‐Fe2O3 but lower than those of r‐SS1 and r‐SS2.

Authors: Rosales Pérez Alicia , Esquivel Escalante Karen 
Published: February 2024

AbstractSonochemistry is the use of ultrasonic waves in an aqueous medium, to generate acoustic cavitation. In this context, sonochemistry emerged as a focal point over the past few decades, starting as a manageable process such as a cleaning technique. Now, it is found in a wide range of applications across various chemical, physical, and biological processes, creating opportunities for analysis between these processes. Sonochemistry is a powerful and eco‐friendly technique often called “green chemistry” for less energy use, toxic reagents, and residues generation. It is increasing the number of applications achieved through the ultrasonic irradiation (USI) method. Sonochemistry has been established as a sustainable and cost‐effective alternative compared to traditional industrial methods. It promotes scientific and social well‐being, offering non‐destructive advantages, including rapid processes, improved process efficiency, enhanced product quality, and, in some cases, the retention of key product characteristics. This versatile technology has significantly contributed to the food industry, materials technology, environmental remediation, and biological research. This review is created with enthusiasm and focus on shedding light on the manifold applications of sonochemistry. It delves into this technique‘s evolution and current applications in cleaning, environmental remediation, microfluidic, biological, and medical fields. The purpose is to show the physicochemical effects and characteristics of acoustic cavitation in different processes across various fields and to demonstrate the extending application reach of sonochemistry. Also to provide insights into the prospects of this versatile technique and demonstrating that sonochemistry is an adapting system able to generate more efficient products or processes.

Published: February 2024

AbstractAlthough biomass‐based alternatives for the manufacturing of bioplastic films are an important aspect of a more sustainable future, their physicochemical properties need to be able to compete with the existing market to establish them as a viable alternative. One important factor that is often neglected is the long‐term stability of renewables‐based functional materials, as they should neither degrade after a day or week, nor last forever. One material showing high potential in this regard, also due to its intrinsic biodegradability and antibacterial properties, is chitosan, which can form stable, self‐standing films. We previously showed that green additives introduce a broad tunability of the chitosan‐based material properties. In this work, we investigate the long‐term stability and related degradation processes of chitosan‐based bioplastics by assessing their physicochemical properties over 400 days. It was found that the film properties change similarly for samples stored in the fridge (4 °C, dark) as at ambient conditions (20 °C, light/dark cycles of the day). Additives with high vapor pressure, such as glycerol, evaporate and degrade, causing both brittleness and discoloration. In contrast, films with the addition of crosslinking additives, such as citric acid, show high stability also over a long time, bearing great preconditions for practical applications. This knowledge serves as a stepping‐stone to utilizing chitosan as an alternative material for renewable‐resourced bioplastic products.

Published: February 2024

SummaryThis article describes a generalized single‐phase multiwinding step‐up transformer‐based multilevel converter with optimized device count. The proposed topology comprises of a single dc source, eight switches (four unidirectional and four bidirectional) and a single high‐frequency multiwinding transformer. Phase disposition pulse width modulation (PDPWM) is used for the level creation. The proposed converter is examined qualitatively and quantitatively using the total number of transformers, PWM control method, switch count, voltage stress, and the number of gate drivers, all of which are favorable. All elements of transformer selection, winding requirements, and comparative study have been thoroughly examined. A thorough Lagrange multiplier method has been applied to minimize the copper losses and optimize the multiwinding transformer (MWT) winding. The proposed converter simulations are performed using the MATLAB/SIMULINK environment. Further, the validation of the result is confirmed by a hardware setup of 0.9 kW.
Current stress optimization of nonagonal MMC for FFTS‐based offshore wind power application

Published: February 2024

SummaryNonagonal Modular Multilevel Converter (MMC) is a new type of three‐port AC‐AC converter suited for applications in FFTS‐based offshore wind power. It can accommodate three AC ports with only nine branches, greatly reducing the cost and size of energy conversion. However, the multiplexing structure of nonagonal MMC inevitably increases the peak branch current resulting in high semiconductor ratings, which weakens its advantage in cost and size. Since the control degrees of freedom are reduced, traditional current attenuation methods are not applicable. To address this issue, in this paper, a parameter adjustment method is proposed for nonagonal MMC to reduce the current stress. By establishing the mathematical model of nonagonal MMC, phase angle difference between ports of nonagonal MMC is proved to be a key influencing factor of peak branch current. By adjusting phase angle difference, the average current stress of nonagonal MMC can be reduced by as great as 66.31%. Finally, the correctness of the conclusions of this paper is verified by RT‐LAB results.
Sensorless control of permanent magnet synchronous motor based on adaptive enhanced extended state observer
Authors: Chen Lijun , Liu Dongliang , Sun Limin , Zhan Chenggen , Zhao Jinyang 
Published: February 2024

SummaryThis article proposes an enhanced adaptive disturbance rejection control strategy for sensorless control of permanent magnet synchronous motor. The traditional fixed bandwidth quadrature phase‐locked loop (Q‐PLL) is insufficient to meet system dynamics in the event of sudden speed changes or motor disturbances, resulting in a significant decrease in control performance. Meanwhile, conventional extended state observers usually rely on a fixed high gain for fast convergence, which raises concerns about their sensitivity to noise. To overcome these challenges, the proposed method introduces a third‐order adaptive cascaded linear extended state observer (ACLESO) in place of the conventional PLL to accurately estimate the speed, phase, and overall disturbances, ensuring timely and accurate estimation of the total disturbance. Then, a speed controller based on linear state error feedback control law (LSEFCL) was designed to enhance the dynamic performance of the system. Based on the stability analysis using the Lyapunov function, finally, extensive experimental tests were carried out to verify the validity of the proposed method.
A new conceptual model for anorexia nervosa: A role for connective tissue?
Authors: Gibson Dennis , Mehler Philip S. 
Published: February 2024

AbstractThe etiology of anorexia nervosa (AN) remains to be fully elucidated, and current theories also fail to account for the direct effect of starvation on the health of the organs and tissues, specifically the connective tissue present in most organs of the body. Individuals with hereditary disorders of connective tissue manifest with clinical symptoms that overlap with AN, as the abnormal connective tissue also contributes to many of the other extra‐articular manifestations of these hereditary disorders. This article hypothesizes that a similar pathophysiology may also contribute to the clinical presentation of AN. Therefore, a better understanding is needed to elucidate: (1) the relationship between abnormal connective tissue and AN, (2) the impact of starvation toward the development of abnormal connective tissue and how this manifests clinically, (3) the etiology of autonomic nervous system changes contributing to the dysautonomia in AN, and (4) how the sensory signals sent from potentially abnormal connective tissue to the central nervous system impact interoception in AN. A conceptual model incorporating abnormal connective tissue is provided.Public SignificanceThe etiology of AN remains poorly understood and current theories fail to account for the direct impact of starvation on the health of the organs and tissues of the body. There is significant clinical overlap between AN and hereditary connective tissue disorders. This paper attempts to provide a new conceptual model for AN in which abnormal connective tissue contributes to the underlying pathogenesis.

Published: February 2024

AbstractIn order to facilitate the synthesis of NHC precursors as well as to incorporate new moieties, the influence of the NHC backbone substitution was investigated within the concept of atropisomeric NHC‐metal complexes. A series of NHC precursors was prepared from new anilines and used to synthesize the corresponding Pd(allyl)Cl(NHC) complexes, most of the time as a mixture of diastereomers (meso and chiral). Chiral HPLC at preparative scale enabled to obtain enantiopure complexes in low to excellent yields. These complexes displayed good activity in the intramolecular α‐arylation of amides and, as a function of the structure of the chiral catalyst, excellent enantioselectivities were reached (up to 96 % ee).
Synthesis and Application of a New Class of Planar and Centrally Chiral Ferrocenyl Amino Alcohol Ligands
Authors: Benson Annette , Cunningham Laura , Guiry Patrick J. 
Published: February 2024

AbstractA family of ferrocenyl amino alcohols (14 examples) has been prepared from the corresponding planar chiral ketones and evaluated as a new class of chiral ligands for asymmetric ethyl‐ and phenylzinc additions to aldehydes. The highly enantioselective synthesis of these ligands is facile, scalable, robust and relies on the use of cheaply available starting materials. Asymmetric ethyl additions proceeded smoothly at ambient temperature, with reaction times as short as 1 hour furnishing the desired products in up to 90 % yield and 99 % ee. The corresponding phenyl additions afforded products in up to 81 % yield and 88 % ee. The observed stereochemical outcome for the addition of diethylzinc was rationalized and the key proposed transition state was supported by an analysis of the X‐ray structures of a series of amino alcohol ligands.

AbstractBeach bar sand bodies are a relatively new type of reservoir in oil exploration where they can be found in the proximity of the source rock. In this study, the genetic type of sand bodies in the Upper Triassic Yanchang Formation in the southwest Ordos Basin is systematically studied through the observation of outcrops, core description, microscopic inspection of thin sections, along with petrophysical properties, mineralogy, and geochemical analysis of trace elements. The results showed that a new sedimentary type of beach bar sand bodies are developed in the Chang 82 submember of the Yanchang Formation, that are generally characterized with a flat bottom and convex top, where the contact interface between the bottom of the single sand body and mudstone is flat, and the bottom lacks erosion and filling structure. Moreover, a variety of wave‐induced sedimentary structures are developed, showing a reverse sedimentary sequence from fine to coarse grains. The structural and compositional maturity of the beach bar sand bodies are higher than that of the river channel sand body. Moreover, reservoir pore type is mainly comprised of intergranular pores, and the porosity and permeability of the samples retrieved from the sand body are much higher than that of the river channel sand body. Finally, the main controlling factors of the formation and preservation of beach bar sands are found to be the lake basin bottom topography, the base level cycle, and the stable paleo‐lake shoreline. During the Chang 82 submember depositional period, a large area where the beach bar sand bodies were deposited parallel to the lake shoreline in the southwest of the basin was created. Such depositional environments had suitable conditions to host large‐scale oil‐bearing reservoirs, as major exploration and development targets in the Ordos Basin in the future.

AbstractThis paper describes and compares the integration of cross‐sector actors' participation into the governance of two local health councils, one located in Salvador de Bahia (Brazil) and the other in the Canary Islands (Spain). Based on the cross‐national comparative research conducted as part of a doctoral thesis, a qualitative design based on secondary data analysis was proposed on the three stages of the organisational integration process of participation. We used information from individual semi‐structured interviews (n = 70), situational observation, focus groups, literature review, and field notes to understand participatory processes of networking between multiple cross‐sector actors and to show how such processes might be associated with innovative practices. For these innovations to be successfully implemented, stakeholders need to acquire adequate competencies in cross‐sector collaboration, enabling them to learn about new organisational practices and to adapt the network of actors to the often unpredictable influences of contextual factors.
A high‐dimensional multinomial logit model
Authors: Nibbering Didier 
Published: February 2024

SummaryThe number of parameters in a standard multinomial logit model increases linearly with the number of choice alternatives and number of explanatory variables. Because many modern applications involve large choice sets with categorical explanatory variables, which enter the model as large sets of binary dummies, the number of parameters in a multinomial logit model is often large. This paper proposes a new method for data‐driven two‐way parameter clustering over outcome categories and explanatory dummy categories in a multinomial logit model. A Bayesian Dirichlet process mixture model encourages parameters to cluster over the categories, which reduces the number of unique model parameters and provides interpretable clusters of categories. In an empirical application, we estimate the holiday preferences of 11 household types over 49 holiday destinations and identify a small number of household segments with different preferences across clusters of holiday destinations.
The molecular circadian rhythms regulating the cell cycle

Published: February 2024

AbstractThe circadian clock controls the expression of a large proportion of protein‐coding genes in mammals and can modulate a wide range of physiological processes. Recent studies have demonstrated that disruption or dysregulation of the circadian clock is involved in the development and progression of several diseases, including cancer. The cell cycle is considered to be the fundamental process related to cancer. Accumulating evidence suggests that the circadian clock can control the expression of a large number of genes related to the cell cycle. This article reviews the mechanism of cell cycle‐related genes whose chromatin regulatory elements are rhythmically occupied by core circadian clock transcription factors, while their RNAs are rhythmically expressed. This article further reviews the identified oscillatory cell cycle‐related genes in higher organisms such as baboons and humans. The potential functions of these identified genes in regulating cell cycle progression are also discussed. Understanding how the molecular clock controls the expression of cell cycle genes will be beneficial for combating and treating cancer.
