Preview control for linear parameter‐varying discrete‐time systems using a linear fractional representation
Authors: Li Li , Lu Yanrong , Ye Hui 
Published: October 2024

AbstractIn order to create a mixed tracking controller for discrete‐time linear parameter‐varying (LPV) systems, this work introduces a unique control strategy employing a linear fractional representation (LFR). Under the premise that the reference signal can be previewable, a design strategy for a controller with preview compensations is suggested. First, a preview tracking control issue is changed into a regulator problem by adding two additional linked auxiliary parameters into the initial system state/input, which further creates more enhanced error systems incorporating future information of reference signals. The suggested conditions then depend on utilizing slack variables with decision matrices related to the LFR approach in order to give innovative preview controller designs. We also construct reduced conservative synthesis situations by taking into account parameter‐dependent Lyapunov functions and full‐block multipliers. In order to create state‐feedback and output‐feedback preview tracking controllers, design requirements are characterized as linear matrix inequalities. Two simulation studies are completed as the last step to highlight how successful the suggested control strategy is.

AbstractOver the past 10 years, nanotechnology has emerged as a very promising technique for a wide range of biomedical applications. Green synthesized metal and metal oxide nanoparticles (NPs) are cheap, easy to produce in large quantities, and safe for the environment. Currently, efforts are being made to dope ZnO in order to improve its optical, electrical, and ferromagnetic qualities as well as its crystallographic quality. Actually, doping is one of the simplest methods for enhancing an NP's physicochemical characteristics because it involves introducing impure ions into the crystal lattice of the particle. In this study, the biosynthesis of zinc oxide NPs (ZnONPs) and metal‐doped (Mg2+ and Ag+) ZnONPs was carried out by using aqueous and water‐alcoholic extracts of Cynara scolymus L. leaves, Carthamus tinctorius L. flowers, and Rheum ribes L. (RrL) plant, which are rich in phytochemical content. Plant extracts act as a natural reducing, capping, and stabilizing agent in the production. The produced NPs were characterized using a variety of methods, such as ultraviolet‐visible spectroscopy, Fourier transform infrared (FTIR) spectroscopy, dynamic light scattering (DLS), and scanning electron microscopy (SEM). The produced metal‐doped and undoped ZnONPs exhibited characteristic absorption peaks between 365 and 383 nm due to their surface plasmon resonance bands. SEM analysis revealed that the NPs were oval, nearly spherical, and spherical. In the FTIR spectra, the Zn–O bonding peak ranges from 400 to 700 cm−1. The peaks obtained in the range of 407–562 cm−1 clearly represent the Zn–O bond. In addition, the FTIR results showed that there were notable amounts of phenol and flavonoid compounds in both the prepared extract and ZnONPs. According to DLS analysis results, the size distribution of produced NPs is between 120 and 786 nm. The antibacterial properties of green produced NPs on Gram‐positive (Staphylococcus aureus RN4220) and Gram‐negative (Escherichia coli DH10B) bacterial strains were investigated by agar well diffusion method. In studies investigating the anticancer activities of biosynthesized NPs, mouse fibroblast cells (L929) were used as healthy cells and human cervical cancer cells (HeLa) were used as cancer cells. Only the produced Ag‐ZnONPs showed potent dose‐dependent antibacterial activity (at concentrations higher than 100 µg/mL) against Gram‐positive and Gram‐negative bacteria. RrL‐ZnONP‐600 and RrL‐ZnONP‐800 NPs produced with water–ethanol extract of RrL plant and calcined at 600 and 800°C were effective at high concentrations in healthy cells and at low concentrations in HeLa cancer cells, showing that they have the potential to be anticancer agents. The study's findings highlight the potential of green synthesis techniques in the production of medicinal nanomaterials for the treatment of cancer and other biological uses.

AbstractAconiti Lateralis Radix praeparata (also known as Fuzi in Chinese) has been extensively used in clinic. However, the toxicity issues limit the therapeutic range of Fuzi. Thus, a rapid and sensitive HPLC‐MS/MS method was developed to simultaneously quantify and compare six active/toxic constituents in decocting extracts from four different processed Fuzi products and in rat plasma after oral administration of its decocting extracts. The selectivity, linearity, sensitivity, precisions, accuracy, matrix effects, extraction recoveries, and stability were validated. The comparative analysis of six alkaloids in decocting extracts between the four kinds of Fuzi products were conducted by the validated HPLC‐MS/MS. Principal component analysis (PCA) and orthogonal partial least‐squares discriminate analysis (OPLS‐DA) were adopted to compare the differences of decocting extracts from the different processed Fuzi products. Besides, selecting Heishunpian (HSP) as the representative of the processed Fuzi products, we investigated the pharmacokinetic behaviors of these major alkaloids after oral administration. The developed HPLC‐MS/MS method to simultaneously analyze these aconitine‐type alkaloids in decocting extracts, and its pharmacokinetic behavior after oral administration may pave a way for quality control of Fuzi and monitoring the safety and rationality of clinical prescriptions.

ABSTRACTBackgroundRhabdomyosarcoma (RMS) is a rare malignant soft tissue sarcoma (STS), accounting for almost 50% of pediatric STSs. Due to its heterogeneity, RMS presents challenges in diagnosis and treatment, with prognosis varying depending on multiple factors. Tumors localized in the other site (OTH)—including the paraspinal, perianal, thoracic, abdominal, pelvic, and perineal regions—are generally classified as unfavorable. This study assesses the clinical features and prognoses of RMS in OTH locations depending on its site of origin.MethodsAn explorative analysis of RMS cases from the SEER 17 database 2000–2020 was conducted. Patients of all ages with histologically confirmed RMS as primary malignant disease classified under OTH, were included. OTH was categorized in four granular site classifications. Overall survival (OS) and disease‐specific survival (DSS) were analyzed using Kaplan–Meier estimators. Factors independently influencing survival, including a site classification model presented in this study, were identified through Cox regression analysis.ResultsOut of 4168 patients with RMS, 990 cases of RMS with the OTH site met the inclusion criteria. The median age was 16 years. The predominant histological subtypes were embryonal (33.0%) and alveolar (25.5%). Most tumors were ≥ 5 cm (median 9 cm) and located primarily in the pelvic region (41.5%). The 3‐, 5‐, and 10‐year OS rates were 45.4% ± 3.332 (95% CI), 40.7 ± 3.332, and 38.6% ± 3.332, respectively, while DSS rates were 43.3% ± 3.136 (95% CI), 38.3% ± 3.136, and 35.1% ± 3.332. In the multivariate analysis age, histological type, site in a granular categorization, stage, regional lymph node examination, and regional lymph node involvement (pathologically proven) were independently associated with survival. Through both univariate and multivariate analyses, an OTH favorable group could be established. The OTH favorable group consists of the anal region, gallbladder and biliary tract, and breast.ConclusionRMS in OTH shows significant differences in prognosis, putting the current categorization as unfavorable into question and making a more detailed classification necessary. Furthermore, pathological regional lymph node assessment is specifically in the OTH localization recommended.

AbstractBackgroundProvisional single stenting strategy (PSS) is a default strategy for percutaneous coronary intervention (PCI) of unprotected left main distal bifurcation lesions (ULMD). Previous study reported that a bifurcation angle change (BAC) between end diastole and systole was associated with outcomes after PCI with double stent strategy (DSS) for ULMD. However, there are no data comparing outcomes after PCI with PSS versus DSS according the degree of BAC.ObjectivesWe evaluated outcomes after PCI with PSS versus DSS for true ULMD with small and large BAC.MethodsWe identified 566 patients with true ULMD underwent PCI in three high‐volume centers. We calculated the BAC in ULMD between end‐diastole and systole before stenting with 2‐dimensional quantitative coronary angiographic assessment. We defined small (BAC < 7.0°) and large BAC (≥7.0°) group. We compared clinical outcomes after PCI with PSS versus DSS in each cohort after propensity score adjustment. The primary endpoint was target‐lesion failure (TLF), which was defined as a composite of cardiac death, target lesion revascularization, and myocardial infarction.ResultsIn small BAC cohort, TLF rate was significantly lower in DSS group than in PSS group (12.5% vs. 20.1%, adjusted HR 0.45; 95% CI, 0.26–0.79; p = 0.006). In contrast, in large BAC cohort, TLF rate was significantly higher in DSS group than in PSS group (54.9% vs. 29.0%, adjusted HR 2.25; 95% CI, 1.50–3.38; p < 0.001).ConclusionsThe TLF rate after PCI with DSS was significantly lower in true ULMD with small BAC compared to PSS even after propensity score adjustment. In contrast, it was significantly higher in those with large BAC.

Published: October 2024

AbstractBackground and ObjectiveThis study aimed to assess the potential of incorporating ultrasonication treatment into the soaking process before germination as a method to enhance the nutritional profile of amaranth. While ultrasound has been used to expedite germination in various grains, its impact on germinated grains from a food science perspective remains underexplored. The research focused on the effects of ultrasonication on the composition, functional, and rheological properties of amaranth grains post‐germination.FindingsThe study revealed that germination alone significantly increased γ‐aminobutyric acid (GABA), protein content, phenolic acids, amino acids, and total dietary fiber while reducing phytic acid and rheological parameters. Incorporating ultrasonication during soaking further elevated amino acids, GABA, protein, and phenolic acid levels. Notably, ultrasonication increased protein content by 25%, antioxidants by 35%, and dietary fiber by 20%, and attributed to cell wall breakdown and enhanced enzymatic activity during germination. Phytic acid levels decreased by up to 95% with prolonged ultrasonication, enhancing nutritional quality. Additionally, GABA levels revealed a significant rise, with an 82% and 87% increase in the Annapurna and Durga varieties, respectively. The study also found that ultrasonication led to reduced starch content, decreased pasting properties, and increased sugar content in the grains. Muffins made with ultrasonicated amaranth showed lower water activity levels, indicating better shelf stability, though specific volume decreased due to starch breakdown and increased amylase activity.ConclusionThe study demonstrates that ultrasonication combined with germination is an effective method for enhancing the nutritional and functional properties of amaranth grains. This method significantly boosts health‐promoting components like GABA, proteins, and antioxidants while also affecting key baking quality parameters.Significance and NoveltyThis research introduces a novel application of ultrasonication to improve the physiochemical, antioxidant, functional, and rheological properties of amaranth grains. The findings suggested a promising strategy for developing nutrient‐rich, functional food ingredients, addressing the growing demand for healthier food products.

Published: October 2024

AbstractSulfur/carbon copolymers have emerged as promising alternatives for conventional crystalline sulfur cathodes for lithium‐sulfur batteries. Among these, sulfur‐n‐1,3‐diisopropenylbenzene (S/DIB) copolymers, which present a 3D network of DIB molecules interconnected via sulfur chains, have particularly shown a good performance and, therefore, have been under intensive experimental and theoretical investigations. However, their structural complexity and flexibility have hindered a clear understanding of their structural evolution during redox reactions at an atomistic level. Here, by performing state‐of‐the‐art ab initio molecular dynamics‐based Raman spectroscopy simulations, we investigate the spectral fingerprints of S/DIB copolymers arising from local structures during consecutive reactions with lithium. We discuss in detail Raman spectral changes in particular frequency ranges which are common in S/DIB copolymers having short sulfur chains and those consisting of longer ones. We also highlight those distinctive spectroscopic fingerprints specific to local S/DIB structures containing only short or long sulfur chains. This distinction could serve to help distinguish between them experimentally during discharge. Our theoretically predicted results are in a good agreement with experimental Raman measurements on coin cells at different discharge stages. This work represents, for the first time, an attempt to compute Raman fingerprints of sulfur/carbon copolymer cathodes during battery operation including quantum‐chemical and finite‐temperature effects, and provides a guideline for Raman spectral changes of arbitrary electrodes during discharge.
A C3‐Symmetric Structurally Twisted Molecular Architecture: Mechano‐/Fluorochromic Behavior and Selective Multiphase Detection of Pd(II)

Published: October 2024

AbstractTriaminoguanidinium (TG)‐based C3‐symmetric‐like molecular architectures with diverse donors and acceptors are well established as organic molecular materials for promising stimuli‐responsive and metal sensing‐based applications. However, the mechanofluorochromic (MFC) response was unremarkable upon applying external mechanical stress. Even though some show MFC features, there was no optical shift under ambient light. In this paper, we developed a novel C3‐symmetric molecule, TAC3, containing the TG core linked with conformationally twisted thiophene‐linked anthracenyl terminals. Three conformationally deformed hands in TAC3 respond against external mechanical stimuli with a redshifted absorption and emission, easily detectable through the naked eye. Although MFC features were reported before for such C3‐symmetric molecules, the change in absorbance was not identified. In addition, TAC3 could selectively detect Pd2+ through extreme emission quenching (green to black). The mechanochromism and sensing outcomes are elucidated by the experimental and theoretical support. Compared to the previous reports, the notable 2 : 3 (metal: ligand) binding due to geometric restriction creating a specific pocket size for Pd+2 is unusual for this system. The onsite application on Pd2+ detection and measurable MFC features are demonstrated to validate the potential of this C3‐symmetric molecule in advanced optoelectronic applications such as security writing and Pd2+ ion detection.
Variation in Community Structure and Abundance of Fish in Simple Structured Shallow Sandy Habitats
Authors: Veneranta Lari , Westerbom Mats 
Published: October 2024

ABSTRACTSandy beaches and their surf zones characterise many of the world's open coastlines. They are important breeding, nursery and feeding areas for many species of fish. Despite the commonness and importance of sandy beach surf zones, the dynamics, space occupancy and diversity patterns of residing fish is in many places poorly understood. The aim of this study was to (1) characterise the fish community structure in 11 simple structured sandy surf zones of the northern Baltic Sea and (2) relate variation in fish abundance and community structure to a set of chosen abiotic variables. Using beach seine, weekly or biweekly sampling was conducted at fixed sites at 10 occasions throughout a summer season. A total of 60,006 fish individuals belonging to 20 species were recorded. Changes in abundance and community structure were mainly driven by the variation of only five species reflecting species‐specific recruitment patterns and different spatial responses to abiotic variables. Dominating groups were Gasterosteidae, Ammodytidae and Gobiidae that together formed 86% of the total adult fish catches. Larval numbers were completely dominated by Gobiidae. Multivariate analyses indicated species‐specific responses to measured environmental variables, most important being a combination of wave exposure, beach slope, bottom roughness, and temperature. The present study shows that changes in fish abundance on simple structured sandy sublittoral beaches in the northern Baltic Sea are large over the course of a breeding season. It also reveals that variation in adult and juvenile fish are driven by a set of abiotic factors that influence on the fish assemblage structure through mainly species‐specific, rather than through generic responses. Unravelling the degree to which the sandy shore fish community vary in the northern Baltic Sea will help in managing coastal environments that are increasingly being threatened by many anthropogenic stressors.

ABSTRACTThis paper describes the application of a physically based agrohydrological model (named FLOWS), coupled with a kinematic wave approach model (named KWV) for water and solute runoff routing, for interpreting the fate of water and nutrients coming from cultivated fields to surface drainage network located in ‘Piana del Sassu’ in the Arborea plain, a hydraulically reclaimed area with shallow groundwater. Modelling was supported by a large complex database on soil, groundwater and surface drainage water, which was used for establishing the boundary conditions for simulations, as well as for calibrating and validating the model. The model FLOWS provided the water and nutrient fluxes to the surface water, which were passed to the KWV model for their routing along the elementary fields in the experimental area and from these to the ditches and finally to the drainage channel. The modelling approach effectively predicted the water and solute distribution along the soil profile, as well as the losses of water and nutrients to the surface water. The results showed a significant amount of water and dissolved nutrients to flow quickly from the soil uppermost layer to the surface drainage network during both the irrigation season and during rainfall events. During irrigation applications, losses were mostly due to rainfall intensity exceeding the maximum infiltration velocity of the shallow soil layer in the case of sprinkler irrigation and to subsurface lateral drainage in the case of exceeding irrigation water provided by drip irrigation. This makes the Sassu plain a significant contributor of nutrients (nitrate and phosphorus) to the surface water. Consequently, even though the agricultural activities might not be an important issue for the groundwater vulnerability, the management of water and nutrients should be significantly improved to avoid ecohydrological threats to the important coastal water bodies present in the area.
