Abstract
In this report, the galvanic corrosion inhibition between Cu and Ru metal films is studied, based on bonding orbital theory, using pyridinecarboxylic acid groups which show different affinities depending on the electron configuration of each metal resulting from a π-backbonding. The sp2 carbon atoms adjacent to nitrogen in the pyridine ring provide π-acceptor which forms a complex with filled d-orbital of native oxides on Cu and Ru metal film. The difference in the d-orbital electron density of each metal oxide leads to different π-backbonding strength, resulting in dense or sparse adsorption on native metal oxides. The dense adsorption layer is formed on native Cu oxide film due to the full-filled d-orbital electrons, which effectively suppresses anodic reaction in Cu film. On the other hand, only a sparse adsorption layer is formed on native Ru oxide due to its relatively weak affinity between partially filled d-orbital and pyridine groups. The adsorption behavior is investigated through interfacial interaction analysis and electrochemical interaction evaluation. Based on this finding, the galvanic corrosion behavior between Cu and Ru during chemical mechanical planarization (CMP) processing has been controlled.

Published: August 2021

Abstract
Dissociation of a ligand isoniazid from a protein catalase was investigated using all-atom Molecular Dynamics (MD) simulations. Random Acceleration MD (τ-RAMD) was used where a random artificial force applied to the ligand facilitates its dissociation. We have suggested an approach to extrapolate such obtained dissociation times to the zero-force limit that was never attempted before, thus allowing direct comparison with experimentally measured values. We have found that our calculated dissociation time was equal to 36.1 seconds with statistically significant values distributed in the interval 0.2-72.0 s, that quantitatively matches the experimental value of 50 ± 8 seconds despite the extrapolation over nine orders of magnitude in time.

Published: August 2021

Abstract
This study is on the effect of stock market volatility on some selected macroeconomic performance indicators in Nigeria. The first objective was the identification of the determinants of stock market volatility in Nigeria. The second objective was the investigation of the effects of stock market volatility on some selected macroeconomic performance indicators in Nigeria. The third objective was the examination of the causal relationship between stock market volatility and selected macro-economic performance indicators in Nigeria from 1981-2019. The study used secondary data sourced from central bank of Nigeria and World Bank databank. The variables that turned out to be significant determinants of stock market volatility using the ECM are exchange rate, total savings, consumer price index, foreign direct investment and inflation.The results from the findings reveal the presence of long run relationship between the variables. This was shown using the Johansen co-integration test which helped to check for long run relationship between the variables. The results further reveal that causality exists between the variables.This study therefore recommends that the government of Nigeria should make consensus effort towards the revitalization and improvement in the overall efficiency of the significant determinants of stock market volatility in Nigeria, because if this improves the Nigerian stock market it can boost the growth of the overall economy.
“To be seen” – Older Adults and Their Relatives’ Care Experiences Given By a Geriatric Mobile Team (GerMOT)

Published: August 2021

Abstract
Background: The proportion of older people in the population has increased globally and has thus become a challenge in health and social care. There is good evidence that care based on comprehensive geriatric assessment (CGA) is superior to the usual care found in acute hospital settings; however, the evidence is scarcer in community-dwelling older people.This study is a secondary outcome of a randomized controlled trial of community-dwelling older people in which the intervention group (IG) received CGA-based care by a geriatric mobile geriatric team (GerMoT). The aim of this study is to obtain a better understanding, from the patients’ perspective, the experience of being a part of the IG for both the participants and their relatives.Methods: Qualitative semistructured interviews of twenty-two community dwelling participants and eleven of their relatives were conducted using content analysis for interpretation.Results: The main finding expressed by the participants and their relatives was in the form of feelings related to safety and security and being recognized. The participants found the care easily accessible, and that contacts could be taken according to needs by health care professionals who knew them. This is in accordance with person-centred care as recommended by the World Health Organisation (WHO) for older people in need of integrated care. Other positive aspects were recurrent health examinations and being given the time needed when seeking health care. Not all participants were positive as some found the information about the intervention to be unclear especially regarding whom to contact when in different situations. Conclusions: CGA-based care of community-dwelling older people shows promising results as the participants in GerMoT found the care was giving a feeling of security and safety. They found the care easily accessible and that it was provided by health care professionals who knew them as a person and knew their health care problems. They found this to be in contrast to the usual care provided, but GerMoT care did not fulfill some people’s expectations.

Published: August 2021

Abstract
This research examines the ability of soft computing approaches (i.e. Linear Regression (LR), Gaussian Process regression (GP), Adaptive neuro-fuzzy inference system (ANFIS),Support Vector Machine (SVM) and deep neural network (DNN)) to predict the undrained shear strength (SU) of soil mixed waste crushed tires. Data set consisting of 72 different samples were used and obtained from the laboratory experiments. Out of 72 experimental observations randomly separated 50 observations were selected for model development whereas residual 22 were selected for the validation of the developed models. Input data set consist of vertical stress, percentage of the crushed tire, percentage of clay, size of clay, specific gravity of tires, Liquid limit, Plastic limit and Specific gravity of clay samples were considered as inputs whereas undrained shear strength of stabilized soil using waste crushed tires material (SU) was considered as output. Five most popular goodness fit assessment parameters were used for the comparison among developed models. Results suggest that DNN based model works superior to other developed models for the prediction of SU the soil samples mixed with tires waste material with coefficient of correlation values as 0.9975, 0.9736, Root mean square error values as 2.4198, 7.5319, Mean absolute error values as 1.8407, 6.1870, Scatter index values as 0.0311, 0.0959 and Nash Sutcliffe model efficiency values as 0.9943, 0.9387 for training and testing stage respectively. Sensitivity analyses offer that specific gravity of tires, size of clay and vertical stress were the most influencing variables in the prediction SU the soil samples mixed with tires waste material.

Published: August 2021

Abstract
Background: Since the COVID-19 outbreak, few studies have investigated the positive psychological consequences on young people. This study examined resilience, positive experiences, and coping strategies reported by Australian adolescents during COVID-19. Methods: Self-report surveys were administered online to a sample of 760 Australian adolescents aged 12-18 years. Quantitative and qualitative methods were used to assess resilience, positive experiences, and coping strategies. Regression analyses were conducted to explore the relationship between resilience and demographics and mental illness history, as well as between resilience and positive experiences. Results: Overall, adolescents were somewhat resilient (M = 20.93, SD = 8.29). They reported positive experiences during COVID-19, including increased empathy, compassion, gratitude, and connection with others, and reported using a range of active coping strategies. Having a mental illness history and identification as female or non-binary gender were associated with lower resilience (Bs > 2.82, ps < .001). Further, resilience was associated with decreased psychological distress (OR = 0.89, p < .001) and with increased positive experiences (ORs > 1.03, ps < .001). Conclusions: Our results indicate that Australian adolescents commonly reported positive experiences and used active coping strategies during COVID-19. Some young people demonstrated higher levels of resilience and were able to make the most out of an unpredictable situation that severely disrupted their daily routine. Resilience-building programs for adolescents may be effective in increasing adaptability after adversity (e.g., climate change, bushfires, pandemics).

Published: August 2021

Abstract
Introduction/AimAnkyloglossia, or ‘tongue-tie’, is a common congenital anomaly in which a short lingual frenulum or genioglossus muscle restricts tongue movement. Ankyloglossia can be graded from 1 (most severe) to 4 (least severe). The effects of ankyloglossia can include breastfeeding and articulation issues; however, many infants will have no symptoms or developmental problems. The surgical intervention for ankyloglossia is frenotomy. This can be performed in the outpatient setting in small infants. Ankyloglossia referrals in neonates and small infants necessitate an urgent referral to the ear nose and throat (ENT) clinic in order to facilitate breast feeding and weight gain. We sought to analyse the ankyloglossia service in a district general hospital setting from referral to outpatient clinic. MethodsWe retrospectively analysed a consecutive cohort of babies referred to the Ear Nose and Throat service for consideration of frenotomy over an 18 month period, We analysed data from referral including demographics and clinical information, we recorded information from the clinical consultation and procedure details if frenotomy was performed.ResultsBetween 1 January 2019 and 31 January 2021 referrals were made for consideration of frenotomy, all appointments were seen within 2 weeks. 55.3% of referrals were sent from public health nurses, 25.5% from primary care, 10.6% from lactation consultants and 8.5% from paediatric consultants. Of 47 referrals, a frenotomy was performed in 30 babies. All frenotomies were performed without complications.ConclusionInformation on ankyloglossia is varied and available information is conflicting, without any clear standardised guideline or treatment algorithm. Referral indications can be unclear and result in unnecessary clinic appointments in an already heavily burdened service. Frenotomy can be performed safely by a trained clinician in an outpatient setting with minimal equipment.

Published: August 2021

Abstract
Estimates of mutation rates for various regions of the mitochondrial genome (mtGenome) vary widely, depending on whether they are inferred using a phylogenetic approach or obtained directly from pedigrees. Traditionally, only the control region, or small portions of the coding region have been targeted for analysis due to the cost and effort required to produce whole mtGenome Sanger profiles. Here, we report one of the first pedigree derived mutation rates for the entire human mtGenome. The entire mtGenome from 225 individuals originating from Norfolk Island was analysed to estimate the population mutation rate and compared against published mutation rates. These individuals were from 45 maternal lineages spanning 345 generational events. Mutation rates for various portions of the mtGenome were calculated. Nine mutations (including two transitions and seven cases of heteroplasmy) were observed, resulting in a rate of 0.063 mutations/site/million years (95% confidence interval: 0.033 – 0.118). These mutation rates are approximately 17 times higher than estimates derived from phylogenetic analysis with heteroplasmy detected in 13 samples (n=225, 5.8% individuals). Providing one of the first pedigree derived estimates for the entire mtGenome, this study provides a better understanding of mtGenome evolution and has relevance to many research fields, including medicine, anthropology and forensics.
Ground-Truth based Performance Assessment of Landslide Susceptibility Mapping: A Case Study after Elazig Earthquake (24 Jan 2020, Mw 6.8), Turkey
Authors: Karakas Gizem , Kocaman Sultan , Gokceoglu Candan 
Published: August 2021

Abstract
Quality assessment for landslide susceptibility maps (LSMs) is essential to increase their usability. Ground-truth based quality assessment is crucial for performance evaluation of LSM production methods. Landslides triggered by earthquakes can be employed for this purpose as they occur frequently throughout the active seismic regions of the world. After an earthquake occurred in Elazig, Turkey on 24 Jan 2020 (Mw 6.8), several landslides were activated in the mountainous parts. Here, the performances of two state-of-the-art machine learning methods, i.e., random forest (RF) and multi-layer perceptron (MLP), were investigated using the activated landslides. The landslide inventory was derived by using pre- and post-event aerial photogrammetric datasets; whereas only the pre-event datasets were utilized for LSM production. The inventory includes activity classes of inactive (L1) and active mass movements (L2), areas having new active zones occurred after 2018 inside the existing landslide (L3), and new activity after 2018 (L4). The L1 and L2 type landslides were used in model training, while L3 and L4 type landslides triggered by the earthquake were used for validation. The area under curve (AUC) values and volumetric change maps obtained from the pre- and post-event datasets were also used for the performance assessment. Furthermore, only a part of the study area was used for model training while the LSMs were produced for the whole area. The results demonstrated that RF exhibited higher classification accuracy (AUC = 0.93) than MLP (AUC = 0.87); and accurate LSMs could be produced by using a sub-part of the basin for training.

Published: August 2021

Abstract
Luminescent inorganic lead halide perovskite nanoparticles lack stability in aqueous solutions, which limits their application to optical sensors. Here, hybrid CsPbBr3-loaded MIP nanogels were developed with enhanced stability in aqueous media. Multifunctional MIP nanogels with antioxidant function and hydrophobic cavities were synthesized from HEMA derivatives in the presence of roxithromycin as a template. The CsPbBr3 nanoparticles were loaded into pre-synthesized MIP nanogels via in-situ synthesis with a size distribution of 200 nm. The developed CsPbBr3-nanogel exhibit excellent stability to air/moisture and enhanced stability toward an aqueous solvent. The developed CsPbBr3-loaded MIP nanogels showed a selective and sensitive detection of ROX with a limit of detection calculated to be 1.7 × 10− 5 µg/mL (20.6 pM). The developed CsPbBr3-loaded MIP antioxidant-nanogels were evaluated on practical application for quantitative determination of ROX antibiotic in animal-derived food products with excellent analytical performance. The detection of ROX in animal-derived food products showed good recovery results making them an ideal candidate for sensing ROX.
Emulating interacting waveguide quantum electrodynamics with wire metamaterials

Published: August 2021

Abstract
Arrays of atoms coupled to photons, propagating in a waveguide, are now actively studied due to their prospects for generation and detection of quantum light. Quantum simulators based on waveguides with long-range couplings were also predicted to manifest unusual many-body quantum states. However, quantum tomography for large arrays with N > 20 atoms remains elusive since it requires independent access to every atom. Here, we present a novel concept for analogue quantum simulations by mapping the setup of waveguide quantum electrodynamics to the classical problem of an electromagnetic wave, propagating in a wire metamaterial. By experimentally measuring the near electromagnetic field we emulate the localization arising from polariton-polariton interactions in the quantum problem. Our results demonstrate the potential of wire metamaterials to visualize quantum light-matter coupling in a table-top experiment and may be applied to emulate other exotic quantum effects, such as quantum chaos, and self-induced topological states.

Abstract
We aimed to investigate the stress-reactive rumination response to social stress and its association with social anxiety and trait rumination. From previous investigations we know that people with a certain vulnerability to rumination show increased stress-reactive rumination. However, up to date the possible influence of social anxiety to this relationship is still unclear. Therefore, we reanalyzed the data of two of our previous studies assessing healthy low and high trait ruminators and depressed patients performing the Trier Social Stress Test (TSST). We measured cortical oxygenation using functional Near-Infrared Spectroscopy (fNIRS) as well as different behavioral outcome measures (subjective stress levels, negative affect, state rumination). On a behavioral level, we found an influence of both, social anxiety and trait rumination, on state rumination, even when correcting for the other factor, respectively, implying two potentially independent factors of influence. On a neural level, we observed reduced activation in socially anxious subjects in the right inferior frontal gyrus (IFG), as well as time-dependent changes in the left IFG and in the right dorsolateral prefrontal cortex. Results indicate a specific role of social anxiety, at least on a behavioral level, and therefore implicate a crucial factor to be considered in the treatment of depression.
Malignancy and Immune Disorders in Patients With Hereditary Angioedema
Authors: Stepaniuk Peter , Kanani Amin 
Published: August 2021

Abstract
Background
With the advent of new therapies, patients with hereditary angioedema (HAE) are living longer lives. Although complement dysregulation has been linked to various disease states, it is currently not known if HAE patients are at an increased risk of developing malignancy or autoimmune conditions.
Case Presentation
: We reviewed the charts of 49 HAE patients and identified 6 patients who had a co-existing malignancy diagnosis (two with breast cancer, one with melanoma, one with pancreatic cancer, one with renal cancer and one with cervical dysplasia) and 6 patients who had a diagnosis of a co-existing immune disorder (two with rheumatoid arthritis, two with ulcerative colitis, one with chronic urticaria with hypothyroidism and one with Sjogren’s syndrome). Nearly all malignancy cases occurred in older HAE patients (> 50 years) and malignancy was diagnosed before HAE in 3 of the patients.
Conclusions
Our case series has identified multiple hereditary angioedema (HAE) patients with co-existing malignancy and immune disorders. Based on these findings, we would advocate that physicians managing HAE patients should maintain a high index of suspicion for these conditions.

Abstract
Ants are among the most successful organisms on earth. It has been suggested that forming symbioses with nutrient-supplementing microbes may have contributed to their success, by allowing ants to invade otherwise inaccessible niches. However, it is unclear whether ants have repeatedly evolved symbioses to overcome the same nutrient limitations. Here, we address this question by comparing the independently evolved symbioses in Camponotus, Cardiocondyla, Formica and Plagiolepis ants. Our analysis reveals the only metabolic function consistently retained in all of the symbiont genomes is the capacity to synthesise tyrosine, which is essential for insect cuticles. We also reveal that in certain multi-queen lineages, only a fraction of queens carry the symbiont, suggesting ants differ in their colony-level reliance on symbiont-derived nutrients. Our results suggest symbioses can arise to solve common problems, but hosts may differ in their dependence on symbionts, highlighting the evolutionary forces influencing the persistence of long-term endosymbiotic mutualisms.
