Carbon nanodots with a controlled N structure by a solvothermal method for generation of reactive oxygen species under visible light
Authors: Saita Satoshi , Kawasaki Hideya 
Published: December 2022

AbstractCarbon nanodots can function as photosensitizers that have the ability to generate reactive oxygen species such as singlet oxygen, hydroxy (OH) radicals, and superoxide ions. However, most of these can only be generated upon ultraviolet light excitation. Additionally, the mechanism of reactive oxygen species generation by carbon nanodots remains unclear. The development of carbon nanodots that can photosensitize under visible light irradiation is desirable for applications such as photodynamic therapy and pollutant decomposition under visible light. Here, we report novel carbon nanodot‐based photosensitizers that generate reactive oxygen species under visible light; they were synthesized using a solvothermal method with two solvents (formamide and water) and amidol as the carbon source. Carbon nanodots from the solvothermal synthesis in formamide showed blue fluorescence, while those obtained in water showed green fluorescence. The photo‐excited blue‐fluorescent carbon nanodots produced OH radicals, superoxide ions, and singlet oxygen, and therefore could function as both type I and type II photosensitizers. In addition, photo‐excited green‐fluorescent carbon nanodots generated only singlet oxygen, therefore functioning as type II photosensitizers. It is proposed that the two photosensitizers have different origins of reactive oxygen species generation: the enrichment of graphitic N for blue‐fluorescent carbon nanodots and molecular fluorophores for green‐fluorescent carbon nanodots.
Scholarly rumors: Citation analysis of vast misinformation regarding parental alienation theory
Authors: Bernet William , Xu Shenmeng 
Published: December 2022

AbstractMisinformation is widespread in political discourse, mental health literature, and hard science. This article describes recurrent publication of the same misinformation regarding parental alienation (PA), that is, variations of the statement: “PA theory assumes that the favored parent has caused PA in the child simply because the child refuses to have a relationship with the rejected parent, without identifying or proving alienating behaviors by the favored parent.” Ninety‐four examples of the same misinformation were identified and subjected to citation analysis using Gephi software, which displays the links between citing material and cited material. The recurrent misinformation reported here is not trivial; these statements are significant misrepresentations of PA theory. Plausible explanations for this trail of misinformation are the psychological mindset of the authors (i.e., confirmation bias) and the authors' writing skills (e.g., sloppy research practices such as persistent use of secondary sources for their information). The authors of this article recommend that publications containing significant misinformation should be corrected or retracted.

Authors: Sánchez‐Obando Jhon W. , Duque‐Méndez Néstor D. 
Published: December 2022

AbstractThere are access restrictions to the technologies of the Fourth Industrial Revolution for rural schools in Colombia. These schools, with few students and teachers geographically dispersed, do not benefit from the possibilities of these technologies in the classroom. These educational institutions are governed by the “Escuela Nueva” model that defines several specific methodological moments. The objective of this study was to design a strategy based on augmented reality (AR) for didactic intervention in the classroom, which allows students to interact with educational resources and break down barriers both related to access to technology and related to the role in learning processes. Educational activities were defined, and a mobile application based on AR was developed for schools in Samaná‐Colombia, integrated with the pedagogical moments of the educational model and at the same time strengthening AMID skills (information literacy and digital media) in the teaching work. Instruments were applied seeking to know the benefits in the classroom and the perception of students and teachers. The results show, preliminarily, that the use of AR in learning activities in this rural school makes it possible to bring students and teachers closer to these technologies, generating motivation and improving the effectiveness of the process, additionally is well accepted in the academic community. Experiments show that if they are included harmoniously in the pedagogical model, it does not interfere, nor is it a distraction for other academic activities. The Contribution paper to empirically validate AR in education generate learning in students of armed conflict zones.
Cold Bent Laminated Glass Application – Numerical Research

Published: December 2022

AbstractIn curvilinear and free‐form glass facade constructions, more and more cold bent laminated glass is applied. The high optical quality of cold bent glass allows for continuously smooth curved and high transparent facades. Moreover, a high performance and economical design is achieved using spatial load‐bearing behaviour. The bending in such curved glass facades is obtained by mechanical fixings upon a curved substructure at the installation on site or by lamination bending with stiff interlayers. These techniques shape the glazing but induce permanent bending stresses as well as shear stresses in the laminated glass, which significantly depend on the interlayer's material behaviour as a function of time and temperature. For the application of cold bent laminated glass in facades numerous factors must be considered ‐ achievable bending radii, glazing dimensions and geometry, load‐bearing capacities, bending forces as well as required supports. These aspects are significantly influenced by the material stiffness of the interlayer type and the glass structure. For this reason, the curved bending process with mechanical line fixings was numerically investigated. The focus lays on the influence of the stiffness of the polymer interlayer and the corresponding suitability for uniaxial cold bent laminated glass applications in different geometries. In the present paper, technical design information is introduced based on numerical simulations to assist designers in understanding the principles of uniaxial cold bent laminated glass with different glazing parameters. In conclusion, constructive recommendations for application in curvilinear glass facades are given.
Forced carbonation – A new method to determine the degree of recarbonation of calcium silicate units
Authors: Walther Hartmut B. 
Published: December 2022

AbstractRebound effects in building materials reduce the CO2 content of the atmosphere. This reabsorption of CO2 during service life and recycling is called recarbonation. In contrast to concrete, detailed knowledge about the CO2 cycles of autoclaved aerated concrete and calcium silicate units is missing. Moreover, standards concerning adequate sampling methods as well as suitable calculation methods do not exist yet.Autoclaved aerated concrete is a highly porous material and recarbonizes evenly. Hence, samples for examination can be drilled out. In contrast, calcium silicate displays lower porosity and decreased CO2 permeability. Therefore, its recarbonation starts on the surface and penetrates inwards. The units are inhomogeneously recarbonized. Consequently, bulk samples – not drill samples – must be taken.In addition, calcium silicate contains considerable amounts of CaO bound in silicates. For this reason, the degree of recarbonation must not be calculated on the basis of the total CaO and CO2 content. The newly developed calculations are based on the maximum CO2 uptake determined using forced carbonation. It is carried out under defined temperature, humidity and CO2 conditions in a climate chamber. Thanks to this method, the degree of recarbonation of calcium silicate can be determined more precisely.

Synthesis of Thioesters from Aldehydes via N‐Heterocyclic Carbene (NHC) Catalyzed Radical Relay
Authors: Man Yunquan , Zeng Xiaojun , Xu Bo 
Published: December 2022

AbstractWe have developed an efficient N‐heterocyclic carbene (NHC)‐catalyzed thioesterification of aldehydes using N‐thiosuccinimides as the thiolation reagent. This organocatalyzed transition involves the generation of sulfur radicals by single electron transfer of the Breslow enolate (generated from aldehyde and NHC catalyst) with N‐thiosuccinimides. This method offers facile access to various highly functionalized thioesters and exhibits good chemical yields and functional group tolerance.

AbstractThe reliable self‐assembly of microporous metal‐phosphonate materials remains a longstanding challenge. This stems from, generally, more coordination modes for the functional group allowing more dense structures, and stronger bonding driving less crystalline products. Here, a novel orthogonalized aryl‐phosphonate linker, 1,3,5‐tris(4’‐phosphono‐2’,6’‐dimethylphenyl) benzene (H6L3) has been used to direct formation of open frameworks. The peripheral aryl rings of H6L3 are orthogonalized relative to the central aromatic ring giving a tri‐cleft conformation of the linker in which small aromatic molecules can readily associate. When coordinated to magnesium ions, a series of porous crystalline metal‐organic, and hydrogen‐bonded metal‐organic frameworks (MOFs, HMOFs) are formed (CALF‐41 (Mg), HCALF‐42 (Mg), ‐43 (Mg)). While most metal‐organic frameworks are tailored based on choice of metal and linker, here, the network structures are highly dependent on the inclusion and structure of the guest aromatic compounds. Larger guests, and a higher stoichiometry of metal, result in increased solvation of the metal ion, resulting in networks with connectivities increasingly involving hydrogen‐bonds rather than direct phosphonate coordination. Upon thermal activation and aromatic template removal, the materials exhibit surface areas ranging from 400–600 m2/g. Self‐assembly in the absence of aromatic guests yields mixtures of phases, frequently co‐producing a dense 3‐fold interpenetrated structure (1). Interestingly, a series of both more porous (530–900 m2/g), and more robust solids is formed by complexing with trivalent metal ions (Al, Ga, In) with aromatic guest; however, these are only attainable as microcrystalline powders. The polyprotic nature of phosphonate linkers enables structural analogy to the divalent analogues and these are identified as CALF‐41 analogues. Finally, insights to the structural transformations during metal ion desolvation in this family are gained by considering a pair of structurally related Co materials, whose hydrogen‐bonded (HCALF‐44 (Co)) and desolvated (CALF‐44 (Co)) coordination bonded networks were fully structurally characterized.

AbstractAimsAcute decompensated heart failure (ADHF) presents with pulmonary congestion, which is caused by an increased pulmonary arterial wedge pressure (PAWP). PAWP is strongly associated with prognosis, but its quantitative evaluation is often difficult. Our prior work demonstrated that a deep learning approach based on chest radiographs can calculate estimated PAWP (ePAWP) in patients with cardiovascular disease. Therefore, the present study aimed to assess the prognostic value of ePAWP and compare it with other indices of haemodynamic congestion.Methods and resultsWe conducted a post hoc analysis of a single‐centre, prospective, observational heart failure registry and analysed data from 534 patients admitted for ADHF between January 2018 and December 2019. The deep learning approach was used to calculate ePAWP from chest radiographs at admission and discharge. Patients were divided into three groups based on the ePAWP tertiles at discharge, as follows: first tertile group (ePAWP ≤ 11.2 mm Hg, n = 178), second tertile group (11.2 < ePAWP < 13.5 mm Hg, n = 170), and third tertile group (ePAWP ≥ 13.5 mm Hg, n = 186). The third tertile group had a higher prevalence of atrial fibrillation and lower systolic blood pressure at admission; a lower platelet count and higher total bilirubin at both admission and discharge; and a higher left atrial diameter, peak early diastolic transmitral flow velocity, right ventricular end‐diastolic diameter, and maximal inferior vena cava diameter at discharge. During the median follow‐up period of 289 days, 223 (41.7%) patients reached the primary endpoint (a composite of all‐cause mortality or rehospitalization for heart failure). Kaplan–Meier analysis revealed a significantly higher composite event rate in the third tertile group (log‐rank test, P = 0.006). Even when adjusted for clinically relevant factors, a higher ePAWP at discharge and a smaller decrease in ePAWP from admission to discharge were significantly associated with higher event rates [ePAWP at discharge: hazard ratio, 1.10; 95% confidence interval (CI), 1.02–1.19; P = 0.010; and size of ePAWP decrease: hazard ratio, 0.94; 95% CI, 0.89–0.99; P = 0.038].ConclusionsOur study suggests that ePAWP calculated by a deep learning approach may be useful for identifying and monitoring pulmonary congestion during hospitalization for ADHF.
Deep learning based seismic response prediction of hysteretic systems having degradation and pinching
Authors: Kim Taeyong , Kwon Oh‐Sung , Song Junho 
Published: December 2022

AbstractThe response of a hysteretic system is determined not only by the instantaneous external force but also by the loading history; thereby, a nonlinear time history analysis is needed for the accurate prediction of dynamic responses. The authors recently developed deep neural network (DNN) models for near‐real‐time seismic response predictions of hysteretic systems (Kim et al., 2019). The DNN models outperform existing regression‐based prediction methods for the idealized hysteretic systems used for the training. Structural systems often show complex hysteretic behavior such as degradation (in stiffness or strength) and pinching effects. In this paper, we develop DNN models for hysteretic systems having degradation and pinching. First, a new Bouc‐Wen class model, termed a modified Bouc‐Wen‐Baber‐Noori (m‐BWBN) model, is proposed to introduce the yield strength as an explicit model parameter. The feasible parameter domains are also specified to promote the practical use of the m‐BWBN model. Second, a seismic demand database is constructed by nonlinear time history analyses using the m‐BWBN model and many ground motions. Third, we propose a new DNN architecture and detailed training methodologies to learn the effects of the complex hysteretic characteristics on the peak seismic responses. Numerical examples of reinforced concrete structures are introduced to test the prediction performance and applicability of the proposed DNN model.

Abstract
Atmospheric micro-/nanominerals play an important role in the adsorption, enrichment, and migration of organochlorine pesticides (OCPs). In the present study, the correlations between OCPs and minerals in outdoor atmospheric dustfall were investigated, and the correlations were used to speculate the source of p,p′-(dicofol+dichlorobenzophenone [DBP]), which is the sum of p,p′-dicofol and p,p′-DBP. Atmospheric dustfall samples were collected from 53 sites in the Chengdu–Deyang–Mianyang economic region in the Sichuan basin. In this region, 24 OCPs were analyzed by gas chromatography–tandem mass spectrometry. The average concentration of 24 OCPs was 51.2 ± 27.4 ng/g. The results showed that the concentration of Σ24OCPs in urban areas was higher than that in suburban areas (p &lt; 0.05). Minerals in atmospheric dustfall were semiquantitatively analyzed by X-ray diffraction. The primary minerals were quartz, calcite, and gypsum. A Spearman correlation analysis of OCPs and minerals showed that low-volatility OCPs could be adsorbed by minerals in atmospheric dustfall. A density functional theory simulation verified that p,p′-(dicofol+DBP) in atmospheric dustfall was primarily derived from the p,p′-dicofol adsorbed by gypsum. Isomeric ratio results suggested that the samples had weathered lindane and chlordane profiles and confirmed that residents in the Sichuan basin used technical dichlorodiphenyltrichloroethane. Finally, the OCPs were evaluated to determine the potential risk of cancer in adults and children from OCP exposure. Exposure to OCPs via atmospheric dustfall was safe for adults. The cancer risk for children exposed to OCPs was slightly lower than the threshold value (10–6) under a high dust ingestion rate, which poses a concern.

AbstractSpecific subfields within the hippocampus have shown vulnerability to chronic stress, highlighting the importance of looking regionally within the hippocampus to understand the role of psychosocial factors in the development of neurodegenerative diseases. A systematic review on psychosocial factors and hippocampal subfield volumes was performed and showed inconsistent results, highlighting the need for future studies to explore this relationship. The current study aimed to explore the association of psychosocial factors with hippocampal (subfield) volumes, using high‐field 7T MRI. Data were from the Memory Depression and Aging (Medea)‐7T study, which included 333 participants without dementia. Hippocampal subfields were automatically segmented from T2‐weighted images using ASHS software. Generalized linear models accounting for correlated outcomes were used to assess the association between subfields (i.e., entorhinal cortex, subiculum, Cornu Ammonis [CA]1, CA2, CA3, dentate gyrus, and tail) and each psychosocial factor (i.e., depressive symptoms, anxiety symptoms, childhood maltreatment, recent stressful life events, and social support), adjusted for age, sex, and intracranial volume. Neither depression nor anxiety was associated with specific hippocampal (subfield) volumes. A trend for lower total hippocampal volume was found in those reporting childhood maltreatment, and a trend for higher total hippocampal volume was found in those who experienced a recent stressful life event. Among subfields, low social support was associated with lower volume in the CA3 (B = −0.43, 95% CI: −0.72; −0.15). This study suggests possible differential effects among hippocampal (subfield) volumes and psychosocial factors.

AbstractLong‐term sperm storage by females in various regions of the oviduct is documented across many invertebrate and vertebrate species. Although, many reports emphasize on the histology, histochemistry and ultrastructural features of sperm storage, very little is known about the mechanisms underlying the sperm storage. The current review documents the occurrence of sperm storage by females in a wide array of invertebrate and vertebrate species. This review also provides an insight on the presence of various molecular factors of the sperm storage tubules presumably responsible for the prolonged sperm storage with an emphasis on a model reptile, the Indian garden lizard, Calotes versicolor which contains a unique approximately 55‐kDa protein in its utero‐vaginal lavage and found to inhibit washed epididymal sperm motility in a concentration and time‐dependent manner in a reversible fashion.
