Published: November 2022

AbstractWater contamination is a global issue which must be addressed and examined in all water resource policies. In recent decades, Pollution from azo dyes has become a significant cause of concern in the environment. Oxidation procedures are preferred to break down organic molecules found in wastewater. Electrochemical advanced oxidation processes are among the most successful methodologies for pollutant degradation and inspired by the efficiency of the photo electro‐Fenton (PEF). It has been conducted for removals of organic pollutants using anode (Ti), Stainless Steel cathode. Reactive Yellow 186 (RY 186) azo dye in sulphate medium was subjected to this study pH (2–9), dye concentration (0.05–0.25 g/l), Iron dosage (0.01–0.03 g/l), H2O2 (0.1–0.5 g/l) dosage, and current density (0.1–0.5 mA/cm2) of PEF were evaluated. The optimum pH, RY 186 concentration, Iron dosage, H2O2 dosage, and current density were found to be approximately 3, 0.15 g/l, 0.015 g/l, 0.2 g/l, and 0.1 mA/cm2, respectively. It was concluded that acidic pH was required to increase the degradation efficiency of the PEF at optimum conditions and a reaction time of 15 min. The PEF approach was the most effective method for the reasons, hydroxyl radical oxidation and UVA radiation, degradation of up to 99%, and COD removal was 94.82% with optimized parameters. Degradation and COD analysis tracked with high‐performance liquid chromatography and infrared spectroscopy analysis. The results were compared with theoretical zero, first and second‐order models. it was found that the process obeys pseudo‐first‐order kinetic and the studies found to fit the data well (R2 = 0.9824). The cyclic voltammetry technique was employed to investigate the PEF process.

Published: November 2022

AbstractTurn‐taking in dialogue is an essential part of communication and early language experience. The prevalence of utterances and the timing of responses in dialogue were examined at 14 and 36 months of age in 104 mother–child dyads from the Early Head Start Research and Evaluation Project (EHSREP). Mothers varied in their level of depression risk (measured with the Center for Epidemiological Studies‐Depression scale; CES‐D). Although maternal utterance rate did not vary significantly across any factors, the latency of mothers' responses to their children decreased with development (12 ms/month) and was significantly related to that of their own children (i.e., slow‐responding children had slow‐responding mothers). Mothers with higher levels of depressive symptoms were 11% slower in responding to their children than mothers with low depression risk, suggesting that the interactive timing of speech to children may be particularly sensitive to maternal depression, modifying the contingent properties of children's early language experience.

AbstractTo explore the prognostic values of baseline 2‐deoxy‐2‐[18F] fluoro‐D‐glucose (FDG) positron emission tomography/computed tomography (PET/CT) dissemination parameter in angioimmunoblastic T‐cell lymphoma (AITL) and its added values to total metabolic tumour volume (TMTV). Eighty‐one AITL patients with at least two FDG‐avid lesions in baseline PET/CT were retrospectively included. PET parameters including TMTV and the distance between the two lesions that are the furthest apart (Dmax) were obtained. Univariate Cox analysis showed that both Dmax and TMTV were risk factors for progression‐free survival (PFS) and overall survival (OS). Multivariate Cox analysis models of different combinations showed that high Dmax (> 65.7 cm) could independently predict both PFS and OS, while high TMTV (>456.6 cm3) was only significant for OS. A concise PET model based on TMTV and Dmax can effectively risk‐stratify patients. PFS and OS rates were significantly lower in patients with high Dmax and high TMTV than in patients with low Dmax and low TMTV (3‐year PFS rate: 15.0% vs. 48.7%, p = 0.001; 3‐year OS rate: 27.6% vs. 79.0%, p < 0.001). Dmax can directly reflect the disease dissemination characteristic and has a significant prognostic value for FDG‐avid AITL patients. It has the potential to be introduced into new risk stratification models for tailored treatment.

Published: November 2022

AbstractVeno‐occlusive disease/sinusoidal obstruction syndrome (VOD/SOS) is a rare, serious complication following haematopoietic cell transplantation (HCT). This systematic literature review evaluated differences in clinical manifestations of VOD/SOS post‐HCT in adults and children. Medline and Embase were searched up to 4 March 2021 for reports of VOD/SOS post‐HCT; VOD/SOS diagnostic guidelines were included. Publications were evaluated based on inclusion of five cardinal clinical features of VOD/SOS (ascites, hepatomegaly, hyperbilirubinaemia, right upper quadrant [RUQ] pain and weight gain ≥5%). Overall, 204 publications were included. At diagnosis, hyperbilirubinaemia was more common in adults (93%) versus children (82%), weight gain ≥5% and hepatomegaly were more common in children (86%, 89%) versus adults (73%, 76%) and ascites and RUQ pain were similar between age groups. While 40% of cases had all five cardinal features, age was not a substantial determinant of the likelihood of missing any single specific feature. The proportion of cases, where hyperbilirubinaemia was the first recorded feature, was higher in children versus adults; weight gain and RUQ pain appeared first in a greater proportion of adults versus children. VOD/SOS diagnosis can be challenging; features may not present in a distinct sequence. This necessitates continuous vigilance by those involved in patient monitoring post‐HCT.

Published: November 2022

AbstractWe examine the impact of multinationals oil companies' (MOCs) corporate social responsibility (CSR) on enhancing land rights for rural women. A total of 1200 women were sampled across the Niger Delta region of Nigeria. Results from the use of a combined propensity score matching and logit model show that MOCs' CSR using global memorandum of understanding (GMoU) model recorded significant success in various policy mechanisms to improve gender equality in land access. The linkages include joint‐titling modalities, land leasing, land use certificate issuances, and community and territorial land delimitation interventions for both agricultural production and security in Nigeria's oil host communities.
A general theory of de‐internationalization
Authors: Lim Weng Marc , Mandrinos Symeon 
Published: November 2022

AbstractDe‐internationalization is a novel phenomenon that is gaining significant attention because of its proliferation in international business. However, unlike internationalization, literature on de‐internationalization remains opaque and scarce, whereby the acts that characterize de‐internationalization and the characters of those acts have remain largely underexplored. To address this knowledge gap and contribute to the body of knowledge on international business, this article aims to shed light on the acts and characters of acts defining de‐internationalization. To do so, this article adopts a taxonomic method to conceptual development. In doing so, this article explains that (1) the act of de‐internationalization can manifest as a firm's decision to adapt and stay or withdraw and exit an international market (what is happening), which can occur through (2) decoupling or psychic distance (how it is happening) due to (3) a means‐ends or a needs‐ends reason (why it is happening), respectively. Taken collectively, this article makes a seminal contribution by establishing a general theory of de‐internationalization.

Published: November 2022

ObjectivesThe objective of this study is to determine whether machine learning may be used for objective assessment of aesthetic outcomes of auricular reconstructive surgery.MethodsImages of normal and reconstructed auricles were obtained from internet image search engines. Convolutional neural networks were constructed to identify auricles in 2D images in an auto‐segmentation task and to evaluate whether an ear was normal versus reconstructed in a binary classification task. Images were then assigned a percent score for “normal” ear appearance based on confidence of the classification.ResultsImages of 1115 ears (600 normal and 515 reconstructed) were obtained. The auto‐segmentation task identified auricles with 95.30% accuracy compared to manually segmented auricles. The binary classification task achieved 89.22% accuracy in identifying reconstructed ears. When the confidence of the classification was used to assign percent scores to “normal” appearance, the reconstructed ears were classified to a range of 2% (least like normal ears) to 98% (most like normal ears).ConclusionImage‐based analysis using machine learning can offer objective assessment without the bias of the patient or the surgeon. This methodology could be adapted to be used by surgeons to assess quality of operative outcome in clinical and research settings.Level of Evidence4 Laryngoscope, 133:2413–2416, 2023

AbstractBackgroundPharyngocutaneous fistula (PCF) and salivary leaks are well known complications of head and neck surgery. The medical management of PCF has included the use of octreotide without a well‐defined understanding of its therapeutic mechanism. We hypothesized that octreotide induces alterations in the saliva proteome and that these alterations may provide insight into the mechanism of action underlying improved PCF healing. We undertook an exploratory pilot study in healthy controls that involved collecting saliva before and after a subcutaneous injection of octreotide and performing proteomic analysis to determine the effects of octreotide.MethodsFour healthy adult participants provided saliva samples before and after subcutaneous injection of octreotide. A mass‐spectrometry based workflow optimized for the quantitative proteomic analysis of biofluids was then employed to analyze changes in salivary protein abundance after octreotide administration.ResultsThere were 3076 human, 332 Streptococcus mitis, 102 G. haemolyans, and 42 Granulicatella adiacens protein groups quantified in saliva samples. A paired statistical analysis was performed using the generalized linear model (glm) function in edgeR. There were and ~300 proteins that had a p < .05 between the pre‐ and post‐octreotide groups ~50 proteins with an FDR‐corrected p < .05 between pre‐ and post‐groups. These results were visualized using a volcano plot after filtering on proteins quantified by 2 more or unique precursors. Both human and bacterial proteins were among the proteins altered by octreotide treatment. Notably, four isoforms of the human cystatins, belonging to a family of cysteine proteases, that had significantly lower abundance after treatment.ConclusionThis pilot study demonstrated octreotide‐induced downregulation of cystatins. By downregulation of cystatins in the saliva, there is decreased inhibition of cysteine proteases such as Cathepsin S. This results in increased cysteine protease activity that has been linked to enhanced angiogenic response, cell proliferation and migration that have resulted in improved wound healing. These insights provide first steps at furthering our understanding of octreotide's effects on saliva and reports of improved PCF healing.

AbstractObjectivesThe Future Proofing Study (FPS) was established to examine factors associated with the onset and course of mental health conditions during adolescence. This paper describes the design, methods, and baseline characteristics of the FPS cohort.MethodsThe FPS is an Australian school‐based prospective cohort study with an embedded cluster‐randomized controlled trial examining the effects of digital prevention programs on mental health. Data sources include self‐report questionnaires, cognitive functioning, linkage to health and education records, and smartphone sensor data. Participants are assessed annually for 5 years.ResultsThe baseline cohort (N = 6388, M = 13.9 years) is broadly representative of the Australian adolescent population. The clinical profile of participants is comparable to other population estimates. Overall, 15.1% of the cohort met the clinical threshold for depression, 18.6% for anxiety, 31.6% for psychological distress, and 4.9% for suicidal ideation. These rates were significantly higher in adolescents who identified as female, gender diverse, sexuality diverse, or Aboriginal and/or Torres Strait Islander (all ps < 0.05).ConclusionsThis paper provides current and comprehensive data about the status of adolescent mental health in Australia. The FPS cohort is expected to provide significant insights into the risk, protective, and mediating factors associated with development of mental health conditions during adolescence.

Published: November 2022

AbstractHot excitons are usually neglected in optical spectroscopy in two‐dimensional semiconductors for the sake of momentum conservation, as the majority of hot excitons are out of light cones. In this letter, we elaborate on the contribution of hot excitons to optical properties of monolayer Molybdenum diselenide (MoSe2) with photoluminescence (PL) and PL excitation (PLE) spectroscopy. With the excitation‐intensity‐dependent PL, temperature‐dependent PL and PLE experiments combined with the simulations, we experimentally distinguish the influences of the exciton temperature and the lattice temperature in the PL spectrum. It is concluded that the acoustic phonon‐assisted PL accounts for the non‐Lorentzian high energy tail in the PL spectrum, and the hot exciton effect is significant to linear optical properties of transition metal dichalcogenides. Besides, the effective exciton temperature is found to be several tens of Kelvin higher than the lattice temperature at non‐resonant optical excitation. It indicates that the exciton temperature needs to be carefully taken into account when considering the exciton‐related quantum phase phenomena such as exciton condensation. It is experimentally demonstrated that the effective exciton temperature can be tuned by excitation energy.Key points
The acoustic phonon‐assisted photoluminescence (PL) accounts for the non‐Lorentzian high‐energy tail in the PL spectrum.
“Hot” excitons play a significant role in optical properties of two‐dimensional transition metal dichalcogenides.
The effective exciton temperature could be tuned by excitation energy.

AbstractPurposeThe impact of direct‐acting antivirals (DAAs) on extrahepatic complications in chronic hepatitis C (CHC) patients remains poorly described. We estimated the association of DAAs with cardiovascular events and extrahepatic cancers.MethodsThe prospective ANRS CO22 HEPATHER cohort was enriched with individual data until December 2018 from the French Health Insurance Database (SNDS). CHC patients were enrolled between August 2012 and December 2015 in 32 French hepatology centers. A total of 8148 CHC adults were selected. Cardiovascular events (stroke, acute coronary syndrome, pulmonary embolism, heart failure, arrhythmias and conduction disorders [ACD], peripheral arterial disease [PAD]) and extrahepatic solid cancers were derived from the SNDS. Associations between DAAs and extrahepatic events were estimated using marginal structural models, with adjustments for clinical confounders.ResultsAnalyses of 12 905 person‐years of no DAA exposure and 22 326 person‐years following DAA exposure showed a decreased risk of PAD after DAA exposure (hazard ratio [HR], 0.54; 95% CI, 0.33–0.89), a beneficial effect of DAAs on overall cardiovascular outcomes in patients with advanced fibrosis (aHR, 0.58; 95% CI, 0.42–0.79), and an increased risk of ACD (hazard ratio [HR], 1.46; 95% CI, 1.04–2.04), predominant after the first year following DAA initiation. There was no association between DAAs and extrahepatic cancer risk (HR, 1.23; 95% CI, 0.50–3.03).ConclusionsDAAs were not associated with extrahepatic cancer development or reduction. They were associated with a decreased risk of PAD and an increased risk of ACD, supporting long‐term cardiac monitoring after DAA therapy.
Amorphous silicon carbonitride a‐SiCN thin film coatings by remote plasma chemical vapor deposition using organosilicon precursor: Effect of plasma composition

Published: November 2022

AbstractOur study on amorphous hydrogenated silicon carbonitride thin films produced by remote plasma chemical vapor deposition (RP‐CVD) from 1,1,3,3‐tetramethyldisilazane as a single‐source compound using the H2 + N2 upstream‐gas‐mixture for generation of microwave plasma are reviewed. The effect of nitrogen content in the H2 + N2 mixture fed to a plasma on the rate and yield of the RP‐CVD process, chemical structure, surface morphology, and properties of a‐SiCN films deposited at a constant substrate temperature of TS = 300°C is described. The deposited films were characterized in terms of their chemical structure, surface roughness, density, refractive index, hardness, elasticity, resistance to wear, and friction coefficient. Due to their properties, a‐SiCN films appear to be very promising coatings for improving the surface mechanics of engineering materials used in advanced technologies.
Natural resources, renewable energy, and governance: A path towards sustainable development

Published: November 2022

AbstractBased on data for 48 African countries for the period 2000–2020, we analyse the effects of natural resources on renewable energy development and the mediating effects of governance on that relationship. For this purpose, the Ordinary Least Squares method was used to develop a baseline regression model, and the Generalized Method of Moments (GMM) approach was used for the dynamic model regression. Quantile regression was used for robustness checking across the various distributions of renewable energy. First, we find that natural resources enhance renewable energy development in Africa and that the results are robust across alternative specifications of natural resources and governance, except for forest resources, which have a negative effect on renewable energy development. When robustness is checked through a quantile regression analysis, the results show that the positive effect depends on the conditional distribution of natural resources and the type of natural resource under consideration. The negative effect of total natural resources becomes weaker as we move towards higher quantiles. Second, governance interacts with natural resource rents to generate positive effects across different governance specifications and natural resources, except for coal rent. We thereby derive some relevant implications for renewable energy financing in the Global South.

AbstractMetal nanoparticle (NP) sintering is a prime cause of catalyst degradation, limiting its economic lifetime and viability. To date, sintering phenomena are interrogated either at the bulk scale to probe averaged NP properties or at the level of individual NPs to visualize atomic motion. Yet, “mesoscale” strategies which bridge these worlds can chart NP populations at intermediate length scales but remain elusive due to characterization challenges. Here, a multi‐pronged approach is developed to provide complementary information on Pt NP sintering covering multiple length scales. High‐resolution scanning electron microscopy (HRSEM) and Monte Carlo simulation show that the size evolution of individual NPs depends on the number of coalescence events they undergo during their lifetime. In its turn, the probability of coalescence is strongly dependent on the NP's mesoscale environment, where local population heterogeneities generate NP‐rich “hotspots” and NP‐free zones during sintering. Surprisingly, advanced in situ synchrotron X‐ray diffraction shows that not all NPs within the small NP sub‐population are equally prone to sintering, depending on their crystallographic orientation on the support surface. The demonstrated approach shows that mesoscale heterogeneities in the NP population drive sintering and mitigation strategies demand their maximal elimination via advanced catalyst synthesis strategies.
