Published: August 2023

SummaryThis paper presents a PI‐type adaptive iterative learning control (PI‐AILC) method for nonlinear processes, which targets enhancing system tracking capabilities by adapting setpoints of the PI controller. First, the proposed method employs compact form dynamic linearization technology to obtain a local linear representation of unknown nonlinear systems. Subsequently, the iterative learning controller gain is adaptively updated using the local linear expression to ensure the optimality of the setpoints. Finally, a pre‐learning mechanism for offline data is introduced to augment the efficiency of the iterative mechanism further. The proof of strict convergence for PI‐AILC is established. Experimental results substantiate the efficacy of PI‐AILC.

Published: August 2023

AbstractAn efficient copper‐catalyzed tandem reaction of 1,3‐dibenzylimidazolidine‐2,4‐diones with ortho halo‐benzaldehyde compounds toward chromeno fused imidazolidinone has been developed. This protocol proceeds via one‐pot sequential intramolecular O‐arylation (C−O bond formation) and oxidative acylation (C−C bond formation). The synthetic method has the advantages of easily available starting materials, good functional tolerance, and wide substrate scope, which make this protocol more sustainable and practical. Experimental outcomes demonstrate that radical pathway might be involved in these transformations.
CNTs/Graphene Oxide‐Nickel Phosphate Nanocomposite‐Based Electrochemical Sensor for Detecting H2O2 in Human Serum

Published: August 2023

AbstractMonitoring H2O2 levels in human serum is vital as it is a biomarker for oxidative stress‐induced diseases and neurodegenerative disorders. Thus, an efficient electrochemical sensor is developed for detecting H2O2 in real human serum samples. The sensor is fabricated by modifying the GC surface with two consecutive thin layers namely carbon nanotubes (CNTs), and graphene oxide‐nickel phosphate composite (GRO‐NIPO). Under optimized conditions, the H2O2 sensor in human serum shows excellent catalytic effect in the concentration range (7 nM to 600 μM) with low detection limit 0.55 nM in the low range (7 nM to 1 μM). The combined effect of the catalytic activity of GRO‐NIPO nanocomposite and the large conductive surface area of CNTs improve the sensor's performance. The negative reduction potential of H2O2 at −570 mV improves the anti‐interference ability of the H2O2 sensor toward common interfering species in biological fluids. The layered modified electrode offers good sensitivity and low detection limit for H2O2 compared to other modified electrodes and some methods cited in the literature. Besides, the H2O2 sensor exhibits stable response over four weeks, excellent selectivity, reproducibility, repeatability, and steadiness. The reliability test of the sensor in serum sample shows good recovery of H2O2.

AbstractCharge ordering (CO) phenomena have been widely debated in strongly‐correlated electron systems mainly regarding their role in high‐temperature superconductivity. Here, the structural and charge distribution in NdNiO2 thin films prepared with and without capping layers, and characterized by the absence and presence of CO are elucidated. The microstructural and spectroscopic analysis is done by scanning transmission electron microscopy‐electron energy loss spectroscopy (STEM‐EELS) and hard X‐ray photoemission spectroscopy (HAXPES). Capped samples show Ni1+, with an out‐of‐plane (o‐o‐p) lattice parameter of around 3.30 Å indicating good stabilization of the infinite‐layer structure. Bulk‐sensitive HAXPES on Ni‐2p shows weak satellite features indicating large charge‐transfer energy. The uncapped samples evidence an increase of the o‐o‐p parameter up to 3.65 Å on the thin film top with a valence toward Ni2+ in this region. Here, 4D‐STEM demonstrates (303)‐oriented stripes which emerge from partially occupied apical oxygen. Those stripes form quasi‐2D coherent domains viewed as rods in the reciprocal space with Δqz ≈ 0.24 reciprocal lattice units (r.l.u.) extension located at Q = () and () r.l.u. The stripes associated with oxygen re‐intercalation concomitant with hole doping suggest a possible link to the previously reported CO in infinite‐layer nickelate thin films.
Unintended effects of broadband grants on bank branches
Authors: Kim Minhae 
Published: August 2023

AbstractThe Community Connect Grant (CCG) Program was created in 2002 to provide financial assistance for the provision of broadband service in rural areas. Although it aimed to strengthen the rural economy, it is possible that an increase in internet usage due to the program could have induced bank branch closures, which could have had unintended effects on the economy. This paper discusses the mechanism by which the program affects bank branches and estimates the magnitude of its effects using an event study model and find that receiving benefits from this program decreases the number of bank branches.

Die Lösung dieser Herausforderungen wird der Branche mit den bisher über Jahrzehnte praktizierten Verfahren und Prozessen nicht gelingen. Umso wichtiger ist es, den Weg für die Einführung von Bauen 4.0 zu ebnen. Im vorliegenden Beitrag wird erläutert, was sich hinter dem Begriff Bauen 4.0 verbirgt und welche Rahmenbedingungen die Umsetzung aktuell erschweren. Darauf aufbauend werden mit dem Schwerpunkt der für ausführende Bauunternehmen wichtigen Produktions‐ und Bauphase von Infrastrukturprojekten Empfehlungen, Maßnahmen und erste Ansätze zur Umsetzung präsentiert.
Deduction of the bond law from test on short RC tie in service conditions
Authors: Debernardi Pier Giorgio , Taliano Maurizio 
Published: August 2023

AbstractBond between ordinary steel bars and concrete plays a fundamental role in the behavior of the reinforced concrete. It is associated to the slip between steel and surrounding concrete and determines the variation in the steel and concrete stresses of cracked RC members. The need to formulate simple constitutive bond laws has led the international standards, such as fib Model Code 2010, to adopt an average bond stress versus slip relationship obtained from an extensive experimental campaign based on pull‐out tests. However, in pull‐out tests bond is substantially influenced by the state of stress, deformation and cracking of the concrete. Moreover, in‐service conditions of RC members, in order to study the cracking behavior or the tension stiffening, an ascending distribution of the bond stress is usually considered as it corresponds to an ascending distribution of the slip from the zero slip section to the cracked section and in the literature the bond law is applied as it is. In particular, at the cracked section, the bond stress is maximum. But, this distribution of the bond stress is not confirmed by the experimental results available in the literature concerning the behavior of an RC tie with a length equal to the crack spacing, where close to the cracked sections a descending distribution of the bond stress is observed while the distribution of the slip remains ascending, with null bond stress at the cracked section. The modeling proposed here does not claim to be exhaustive due to the limited albeit accurate experimental data. However, it does indicate the opportunity to abandon bond laws based on experimental works that do not represent the real situation or are far from it.

Abstract

Objective
The Tennessee River basin and its cascade of reservoirs are home to some of the most diverse freshwater fish assemblages in the world. This unique system is threatened by the ongoing invasion of Silver Carp Hypophthalmichthys molitrix and Bighead Carp H. nobilis, hereafter referred to together as “bigheaded carps.” Bigheaded carps may directly compete for food resources with native clupeid species such as Gizzard Shad Dorosoma cepedianum, and this potential interaction could have damaging ecological and economic consequences. High relative abundances of Gizzard Shad are crucial to the Tennessee River food web and associated fisheries because of their role as a forage base for piscivorous species.

Methods
We analyzed a collection of annual gillnetting and electrofishing data spanning from 1990 to 2017 to test whether Gizzard Shad relative abundances have changed in Tennessee River reservoirs since the arrival of bigheaded carps.

Result
Our analyses indicated that Gizzard Shad abundances have been declining but were already declining prior to the arrival of bigheaded carps in the Tennessee River.

Conclusion
At this stage in the invasion, we could not attribute a cause-and-effect relationship to the inverse correlation between Gizzard Shad and bigheaded carps, but we advise continued monitoring of indicators of harmful interactions.
Negotiating Polycentric Power Dynamics in China through Digital Multimodal Composing

Published: August 2023

AbstractDigital multimodal composing (DMC) has been receiving increasing attention in the research on English as an additional language (EAL) instruction in higher education. While this approach responds to students' changing writing practices in the digital world, it can create tension with mandated curricula and high‐stakes testing regimes that prioritize print‐based essay writing as in China. However, little research has explored the possibility of negotiating the tension and bridging DMC and print‐based writing through instructional design. This article reports an instrumental case study that investigates a university instructor's pedagogical approach of using DMC in an academic literacy classroom in China. Through qualitative inductive analysis and multimodal analysis, this study identifies five centers of polycentric power relations and explores how and why the instructor designed, implemented, and evaluated the DMC project to leverage students' digital literacy interests, meet the goals of the national English curriculum, and prepare students for the standardized tests. We argue that she served as a digital literacy broker who not only harnessed students' passion for digital communication but also fulfilled the requirements of different centers.

AbstractNatural killer (NK) cells are gaining popularity in the field of cancer immunotherapy. The present study was designed to investigate the effect of a natural flavonol compound limocitrin in increasing cytotoxicity of a permanent NK leukemia cell line KHYG‐1 against an aggressive leukemia cell line K562. The findings revealed that limocitrin increased the expressions of cytolytic molecules perforin, granzymes A and B, and granulysin in KHYG‐1 cells by inducing phosphorylation of transcription factor CREB, leading to increased lysis of K562 cells. Mechanistically, limocitrin was found to increase the expressions of t‐Bid, cleaved caspase 3, and cleaved PARP to induce K562 cell apoptosis. Moreover, limocitrin reduced the expressions of SET and Ape1 to inhibit DNA repair mechanism, leading to caspase‐independent K562 cell death. At the molecular level, limocitrin was found to increase the phosphorylation of ERK, p38, and JNK to increase granzyme B expression in KHYG‐1 cells. Taken together, the study indicates that limocitrin increases cytotoxicity of NK cells against a range of cancer cells.

ABSTRACTObjectivesThe association between pregestational diabetes mellitus (PDM) and risk of congenital heart disease (CHD) is well recognized; however, the importance of glycemic control and other coexisting risk factors during pregnancy is less clear. We sought to determine the relative risk (RR) of major CHD (mCHD) among offspring from pregnancies complicated by PDM and the effect of first‐trimester glycemic control on mCHD risk.MethodsWe determined the incidence of mCHD (requiring surgery within 1 year of birth or resulting in pregnancy termination or fetal demise) among registered births in Alberta, Canada. Linkage of diabetes status, maximum hemoglobin A1c (HbA1c) at < 16 weeks' gestation and other covariates was performed using data from the Alberta Perinatal Health Program registry. Risk of mCHD according to HbA1c was estimated as an adjusted RR (aRR), calculated using log‐binomial modeling.ResultsOf 1412 cases of mCHD in 594 773 (2.37/1000) births in the study period, mCHD was present in 48/7497 with PDM (6.4/1000; RR, 2.8 (95% CI, 2.1–3.7); P < 0.0001). In the entire cohort, increased maternal age (aRR, 1.03 (95% CI, 1.02–1.04); P < 0.0001) and multiple gestation (aRR, 1.37 (95% CI, 1.1–1.8); P = 0.02) were also associated with mCHD risk, whereas maternal prepregnancy weight > 91 kg was not. The stratified risk for mCHD associated with HbA1c ≤ 6.1%, > 6.1–8.0% and > 8.0% was 4.2/1000, 6.8/1000 and 17.1/1000 PDM/gestational diabetes mellitus births, respectively; the aRR of mCHD associated with PDM and HbA1c > 8.0% was 8.5 (95% CI, 5.0–14.4) compared to those without diabetes and 5.5 (95% CI, 1.6–19.4) compared to PDM with normal HbA1c (≤ 6.1%).ConclusionsPDM is associated with a RR of 2.8 for mCHD, increasing to 8.5 in those with HbA1c > 8%. These data should facilitate refinement of referral indications for high‐risk pregnancy screening. © 2023 The Authors.

AbstractAn outbreak of α‐mannosidosis in a bovine herd from Buenos Aires province is reported. Postmortem examination, histology, lectin histochemistry and electron microscopy were performed on five calves born with nervous signs. Hair samples from dams and calves were genetically analysed. The α‐mannosidase gene including exon 7 was amplified and sequenced. At postmortem examination, no gross changes were evident. Histologically, cytoplasmic neuronal vacuolation in the brain and cerebellum of the five calves, staining moderately to intensively, with lectin histochemistry was evident. Ultrastructurally, vacuoles containing finely granulated material in the cytoplasm of neurons, myelin degeneration and axonal swelling were seen in the brain. Genetic analysis revealed a heterozygous carrier state for 961T→C transition in the exon 7 of α‐mannosidosis gene of four cows, and a recessive homozygous state for 961T→C transition in the same genes in the calves analysed. This highlights the importance of identifying and removing animals carrying the α‐mannosidosis mutated gene.

Published: August 2023

AbstractA 3‐month‐old Warmblood colt was referred for evaluation of coughing and dysphagia. An asymmetrical, short defect of the soft palate and secondary aspiration pneumonia was diagnosed and surgically treated with a standing laryngeal tie‐forward procedure. Intraoperative endoscopy was used to guide the procedure and confirm appropriate epiglottic positioning. By 4 days post‐operatively, the dysphagia resolved. Upper respiratory tract endoscopy performed 2 days post‐operatively confirmed maintenance of the intraoperative laryngohyoid positioning. When contacted 2 years post‐operatively, the owner reported being satisfied with the outcome of surgery. Clinical signs of dysphagia had resolved in 4 days and pneumonia within 2 months of surgery. This report demonstrates that small cleft palate defects can be treated successfully in foals using a standing laryngeal tie‐forward. When used in appropriate cases, the technique provides a valid alternative to primary closure, which mitigates the need for general anaesthesia in a potentially high‐risk population.
The Quebrada Negra wetland study: An approach to understand plant diversity, hydrology, and hydrogeology of high‐Andean wetlands

Published: August 2023

AbstractHigh‐Andean peatlands are high‐altitude wetland ecosystems found throughout the arid central Andes of South America. They form through the establishment of specialized grasses and cushion sedges that are well‐adapted to cold temperatures, in areas where groundwater emerges. The Silala River is a groundwater‐fed high‐Andean fluvial system, which emerges in various springs that generate wetlands, the Cajones and Orientales (Bolivia), the river's headwater sources, and the Quebrada Negra (Chile) being the most important. This article reviews detailed monitoring undertaken in the undisturbed Quebrada Negra wetland to provide insights into wetland processes, and to compare its functioning to that of the Bolivian wetlands, which were channelized a century ago. Vegetation composition was found to be similar among the three wetlands, and their spatiotemporal vegetation cover distribution showed strong seasonal and interannual variability. The channelized Bolivian wetlands have the highest annual actual evapotranspiration values (~700 mm, due to their higher vegetation vigor), as estimated using remote sensing, ~10% greater than that obtained in the undisturbed Quebrada Negra wetland. For the Quebrada Negra wetland, groundwater monitoring revealed that hydraulic head contours are consistent with the topography, although water sources to the wetland are complex to identify. While significant groundwater inflows arise at the wetland edges, upwelling and downwelling conditions are observed at various locations within the wetland, similar to other high‐Andean wetlands. The observations suggest that while the underlying groundwater discharge sustains the saturated conditions of the wetland, the spatial variability of groundwater inputs results in a negligible impact of channelization on wetland evapotranspiration.This article is categorized under:

AbstractThe study aimed to evaluate metabolic parameters, nutrient intake, and absorption of two diets formulated for Dasypus novemcinctus armadillos under human care. Were studied two diets: D1—a diet with dry dog food, ground beef, and boiled chicken egg with shells; D2—a diet with the same ingredients as D1, with added banana and papaya. Both are mixed in water. The parameters analyzed were body weight (BW), weight gain (WG), maintenance energy requirement (MER), Lee index, biometrics, body condition score, glucose, triglycerides, total cholesterol, and cholesterol fractions for eight male armadillos. Dietary intake (DI) and efficiency, nutrient intake, metabolizable energy, and digestibility coefficient for the diets were evaluated in six male armadillos. The diet that included fruits showed higher BW, WG, MER, Lee index, and better glucose metabolism. Both diets promoted increases in WG and Lee Index, as well as improvements in glucose metabolism. The diet without fruit improved the lipid profile of the animals. D2 presented the highest DI, better dietary efficiency, and higher energy intake but also a lower crude fiber intake. However, it showed the best utilization of gross fiber and all other nutrients. In conclusion, the diets constituted an adequate nutritional option for captive armadillos and can be used in malnutrition and pathological processes recovery. Although both diets were adequate, the nonfruit diet was preferable due to the improved lipid profile.
