Published: July 2021

Abstract
Background
Parents are integral in the treatment of pediatric eating disorders. The current study was conducted to further understand the barriers and facilitators that parents experience in accessing specialized, tertiary level eating disorder treatment for children and adolescents. The goals of the study were to understand the processes leading to diagnosis and treatment, perceived barriers and facilitators to accessing care, and parents’ experiences over the course of their child’s eating disorder treatment.

Methods
Ten parents whose children were admitted to a Canadian tertiary level specialized pediatric eating disorders program took part in an exit interview upon their child’s completion of treatment in the program. In-depth semi-structured interviews were combined with a visual timeline. Interpretive induction was performed to generate high-level concepts that emerged from the interviews.

Results
Five high-level concepts were identified: (1) delays in identifying eating disorder symptoms, (2) challenges in accessing eating disorder services, (3) the right treatment at the right time, (4) emotional impact on parents, and (5) parental expertise and involvement.

Conclusions
Several barriers were identified by parents that interfered with treatment, including system-related challenges when accessing specialized eating disorder treatment, concerns about a lack of appropriate mental health support for their child, and difficulties with transitioning between community and tertiary level care. Negative emotions, including guilt and self-blame, were common early in the treatment journey. Themes of parental involvement throughout treatment, and parents taking charge of their child’s recovery, emerged across interviews. The results of this study suggest the importance of early identification of eating disorder symptoms, facilitating smoother transitions between levels of care (e.g., community services and hospital-based eating disorder care), and improving clinical decision-making to ensure children and adolescents with eating disorders receive the most appropriate treatment based on their clinical presentation.

Published: July 2021

Abstract
Background
Accumulating data have suggested that vitamin D receptor (VDR) gene is a pretender gene for vulnerability to Parkinson disease (PD). This study aimed to assess the relationship of VDR gene polymorphisms (FokI and ApaI) with PD. Fifty patients suffering from PD and 50 age- and sex-matched healthy controls were included. Unified Parkinson Disease Rating Scale (UPDRS) was done to assess disease severity. Genetic testing for VDR gene single nucleotide polymorphisms (FokI and ApaI) was done using real time polymerase chain reaction (PCR) technique.

Results
Concerning frequency of genes and alleles for vitamin D receptor gene polymorphisms (FokI and ApaI), no statistically significant difference was found between PD patients and controls. AC genotype was associated with younger age and younger age at onset of disease compared to CC and AA genotypes of ApaI gene polymorphisms. CC genotype was significantly positively correlated with fatigue and urine incontinence. VDR gene polymorphisms were not found to be independent predictors for severity of PD after adjustment for possible confounders.

Conclusion
VDR gene polymorphisms are related to the clinical manifestations rather than etiology or severity of idiopathic PD.

PURPOSE Understanding the distribution of human papilloma virus (HPV) subtypes in limited-resource settings is imperative for cancer prevention strategies in these regions. The objective of our study is to compare the prevalence of cervical HPV genotypes in women across the African diaspora. METHODS This study was approved by the African Caribbean Consortium (AC3). Six member institutions (Benin, Ethiopia, The Bahamas, Tobago, Curacao, and Jamaica) provided independently collected HPV data. Prevalence comparisons across for each nation were performed followed by an assessment of anticipated 9-valent vaccine coverage. Chi-square or Fisher's exact tests were used with significance at P < .05. RESULTS One thousand three hundred fifty high-risk (HR) and 584 low-risk (LR) HPV subtypes were identified in the entire cohort. The most common HR HPV subtype was HPV 16 (17.9%) of infections. The distribution of HR and LR subtypes varied by country. The proportion of HR-HPV subtypes covered by the current 9-valent vaccine was lower in African countries compared with the Caribbean countries (47.9% v 67.9%; P < .01). No significant difference was seen for LR subtypes (8.1% African continent v 5.2% Caribbean; P = .20). Marked variation in the proportion of infections covered by the 9-valent vaccine persisted in individual countries. CONCLUSION Significant variations in HPV prevalence were identified among African and Afro-Caribbean women. A large number of women in these regions are potentially uncovered by current vaccination formulation, particularly low-risk HPV infections.

Published: July 2021

Abstract
Although various lanthanide clusters with different shapes and connections have been synthesised, more rules are still needed to guide their further serial expansion and directed structural modification. Herein, we used the multidentate chelating ligand N′2,N′9-bis((E)-2-hydroxy-3-methoxybenzylidene)-1,10-phenanthroline-2,9-dicarbohydrazide (H4L) to react with Dy(NO3)3·6H2O under EtOH/CH3CN conditions to obtain an example of a nonanuclear dysprosium cluster, i.e., [Dy9(L)2(μ2-OH)(μ3-OH)6(NO3)12(H2O)3]·5CH3CN·H2O (1). The structural framework of cluster 1 contains 2 (L)4− ligands, 1 μ2-OH−, 6 μ3-OH−, 12 NO3−, and 3 H2O. Each ligand (L)4− chelates five Dy(III) ions, and its coordination mode is μ5-η1:η2:η1:η2:η1:η1:η2:η1:η2:η1. Cluster 1 has many different connection modes of NO3−, such as μ5-η2:η2:η2, μ2-η1:η1, and μ2-η1:η2. Notably, we only changed the metal salt to Dy(OAc)3·6H2O and obtained an example of a trinuclear dysprosium cluster, i.e., [Dy3(H2L)(OAc)7]·CH3CN·3H2O (2). The structure of cluster 2 contains three Dy(III) ions, one (H2L)2− ion, one μ3-η2:η2-bridged OAc− and six end-coordinated OAc−. The coordination mode of ligand (H2L)2− is μ3-η1:η1:η2:η1:η1:η1:η2:η1. More notably, we only changed the solvent to MeOH/CH3CN, and under the same reaction conditions, we got an example of a dodeca-nucleus dysprosium cluster, i.e., [Dy12(L)4(μ2-OH)2(OAc)14(H2O)8]·4C2H3O2·2H2O (3). In cluster 3, ligand (L)4− adopts the μ5-η1:η2:η1:η2:η1:η1:η2:η1:η2:η1 coordination mode, and the four ligands (L)4− are connected to each other forming the grid structure. Twelve Dy(III) ions are “embedded” in the chelating sites of the ligand and bridged by multiple OAc− ions. A large cavity is formed in the centre of the ‘well’ in cluster 3. The test results of variable temperature AC magnetic susceptibility show that clusters 1–3 all exhibit single-molecule magnet behaviour. To the best of our knowledge, this study is the first to describe that an out-to-in growth mechanism has been manipulated by anions and solvents to realise the synthesis of a series of completely differently connected dysprosium clusters. In addition, this mechanism is also one of the rare examples of anion and solvent co-induced assembly to form lanthanide clusters with completely different shapes and connections.

Published: July 2021

Abstract
Construction of entangled nanostructures from molecular rings or strands has long attracted chemists, yet synthetic approaches for highly entangled nanostructures remain unexplored to date. Here, we introduce our recent achievements in construction of such nanostructures by utilization of metal–peptide strands. Our folding-and-assembly strategy, that is based on a cooperative processes of peptide self-folding and metal-induced self-assembly, has afforded unprecedented topological nanostructures through threading of multiple metal–peptide rings. Starting from the initial design of the system, we discuss remarkable examples such as polyhedral links, torus knots, and a poly[n]catenane, and state the perspectives in this account review.

Sub-terahertz photonic frequency divider with a large division ratio based on phase locking
Authors: Han Daming , Wei Wei , Liu Zhangweiyi , Xie Weilin , Dong Yi 
Published: July 2021

We present a photonic frequency divider with a large division ratio for microwave signals up to sub-terahertz. A high-operating frequency and a large frequency division ratio have both been achieved by phase-locking a Fabry–Perot frequency comb to the input signal that is to be divided. The input signals ranging from 50.10 GHz to 200.10 GHz are all divided to 2.5 GHz signals, which can be further divided into lower- frequency signals easily. The proposed divider is free of high-speed electrical devices, thanks to the intermediate-frequency detection and feedback control in the phase locking process. Moreover, the phase noise caused by the photonic frequency division is negligible at low offset frequencies, proving that the divider has superior long-term stability. This flexible, cost-efficient, and stable photonic frequency divider is an ideal candidate for frequency division at the remote end of a high-precision frequency transfer system.
Friendships in the field: Methodological recommendations for autoethnographic context
Authors: Ponocná Petra 
Published: July 2021

Abstract
This autobiographically based article aims to consider the practical application of Anderson’s conception of analytic autoethnography under particular circumstances and requirements for its use. It reflects on the friendships that developed between me and my key informants during ethnographic research. In this context I refer to autoethnography as a method that allows researchers to identify aspects of their lives that have relevance beyond the personal and deal analytically with friendships in the field. Moreover, I consider how the researcher can analytically handle friendships in the field using analytic autoethnography, even when he is not a complete member of the community under investigation.
A comparative study and combined application of RSM and ANN in adsorptive removal of diuron using biomass ashes
Authors: Deokar Sunil K. , Gokhale Nachiket A. , Mandavgane Sachin A. 
Published: July 2021

Abstract
Biomass ashes like rice husk ash (RHA), bagasse fly ash (BFA), were used for aqueous phase removal of a pesticide, diuron. Response surface methodology (RSM) and artificial neural network (ANN) were successfully applied to estimate and optimize the conditions for the maximum diuron adsorption using biomass ashes. The effect of operational parameters such as initial concentration (10–30 mg/L); contact time (0.93–16.07 h) and adsorbent dosage (20–308 mg) on adsorption were studied using central composite design (CCD) matrix. Same design was also employed to gain a training set for ANN. The maximum diuron removal of 88.95 and 99.78% was obtained at initial concentration of 15 mg/L, time of 12 h, RHA dosage of 250 mg and at initial concentration of 14 mg/L, time of 13 h, BFA dosage of 60 mg respectively. Estimation of coefficient of determination (R

RHA = 0.976, R

BFA = 0.943) proved ANN (R

BFA = 0.982) fits better. By employing RSM coupled with ANN model, the qualitative and quantitative activity relationship of experimental data was visualized in three dimensional spaces. The current approach will be instrumental in providing quick preliminary estimations in process and product development.

involving n velocities in two spatial and one temporal dimensions, is introduced. Explicit solutions
of the problem are provided by using the inverse scattering method. The model we
propose is a generalization of both the N-wave interaction problem and the

matrix Davey–Stewartson equation. The latter examines the Benney-type
model of interactions between short and long waves. Referring to the two-dimensional
Manakov system, an associated Gelfand–Levitan–Marchenko-type, or
so-called inversion-like, equation is constructed. It is shown that the
presence of the degenerate kernel reads explicit soliton-like solutions of
the dispersive N-wave interaction problem. We also present a discussion on
the uniqueness of the solution of the Cauchy problem on an arbitrary time interval for small initial data.
A survey of Midwest physicians’ experiences with patients in psychiatric distress in the emergency department
Authors: Brodeur Jack , Ley Alyse Folino , Bonnet Michelle 
Published: July 2021

Abstract

Context
Emergency medicine (EM) physicians commonly stabilize patients with acute psychiatric distress, such as suicidal ideation. Research has shown that suicidal ideation is difficult to manage in emergency department (ED) settings and that patients in psychiatric distress are often “boarded” in the ED while awaiting more definitive care.

Objectives
To examine the attitudes and experiences of emergency physicians regarding the care of patients in psychiatric distress. Special attention is given to suicidal ideation due to its prevalence in the United States.

Methods
A 19 question anonymous survey was sent via email to 55 emergency medicine residency directors throughout Michigan, Ohio, Indiana, and Illinois, who were identified using an Internet search of residency programs in the region. The program directors were asked to distribute the survey to their colleagues and residents. The intent of this procedure was to generate as many survey responses as possible, while obscuring the identities of the respondents. Responses were gathered from October 29, 2019 until January 16, 2020. The survey was designed to assess respondents’ self-reported demographic data as well as their experiences with the boarding process, initial examination, final disposition, reevaluation of the patient, physician training and resources, and follow up care. Statistical analysis was performed using a Mann–Whitney U test, significance was set at p<0.01.

Results
In total, 47 EM physicians responded to the survey; however, not all of the respondents completed all 19 questions. Ten of 44 respondents (22.7%) reported that they do not perform the initial psychiatric examination themselves and instead defer to a nurse or social worker. Twenty-two of 44 respondents (50.0%) reported that they defer to a social worker when determining the final disposition of psychiatric patients. Respondents reevaluated patients in psychiatric distress statistically significantly less often (p=0.01) compared with patients with cardiac pathology. Additionally, 15 of 38 respondents (39.5%) reported that they did not feel adequately trained to handle psychiatric emergencies, and 36 of 39 respondents (92.3%) of physicians felt that their facility would benefit from additional mental health resources. Thirty five of 39 respondents (89.7%) reported that their facility did not have a system in place to follow up with suicidal patients upon discharge.

Conclusions
Caring for patients who are acutely suicidal or in psychiatric distress is complex and more research is needed to optimize treatment strategies. The results of this study indicate that EM physicians may regularly defer to nonphysician providers when evaluating and treating patients in psychiatric distress. A perceived lack of training in psychiatry may contribute to this practice. The results of this study are in accord with previous research that indicated a need for additional psychiatry training in EM residencies.
Ecology, physics, process philosophies, Buddhism, Daoism, and language: A case study of William Golding’s The Inheritors and Pincher Martin
Authors: Goatly Andrew 
Published: July 2021

Abstract
Much has been written about the ecological perspectives of Buddhism and Daoism, as examples of philosophies which emphasize process, impermanence, interconnectedness, and compassion for nature. And the interconnectedness of the various elements of the biosphere and the Earth’s crust is the basis of ecological Gaia theory. Some physicists and process philosophers have drawn attention to the inadequacies of European languages to represent the world of quantum reality, radical undifferentiated wholeness and interconnectedness, and the dynamism and uncontrollability of the material world. Notable among these were physicists David Bohm and David Peat, who looked to Blackfoot, an Algonquin language of North America, for a better representation of the natural world as interacting processes.
This article explores some of the commonalities between Buddhism/Daoism, process philosophies, modern physics and ecological theory. It then addresses the question of the affordances different languages and grammars provide for a deep ecological representation in tune with quantum physics and Buddhism/Daoism. The climax of the article starts with the work of Michael Halliday on the local grammar of William Golding’s The Inheritors (Golding, William. 1961 [1955]. The Inheritors. London: Faber), and performs a similar grammatical analysis of two passages from Golding’s later work Pincher Martin (Golding, William. 1956. Pincher Martin. London: Faber). It concludes that the Neanderthal mind style and life style in The Inheritors and the world of the drowning Pincher Martin are represented in a grammatical style more appropriate for a Buddhist/Daoist/quantum physics/deep ecological worldview of human interaction with the natural world.
Evidentiality in science from specialization to popularization: A case study of COVID-19 texts
Authors: Huang Jinyi , Wang Jinjun 
Published: July 2021

AbstractSince the beginning of the COVID-19 pandemic outbreak, medical texts on the pandemic have enjoyed wide popularity, and one of the key issues has always been the accuracy and dependability of the information they contain. The use of evidentiality, a linguistic system which functions to indicate the source and credibility of information, is thus worth exploring in COVID-19 texts. Adopting a synthesized framework within the overall model of systemic functional linguistics, this paper sets out to investigate the lexicogrammar and semantics of evidentiality on the basis of data collected in the form of both specialized and popular texts on COVID-19. Evidentiality in these texts is explored along four dimensions: (i)evidential taxonomy, where specialized texts favor reporting, while popular texts favor belief and inferring; (ii)information source, where specialized texts highlight the voices of authorship, original research, and patients, whereas popular texts highlight the voices of scientists, institutions, countries, and laypeople; (iii)modalization, where specialized texts typically indicate a higher degree of modal responsibility than their popular counterparts; and (iv)engagement, where specialized texts favor dialogic expansion and popular texts favor contraction. It is hoped that these findings will shed light on linguistic variation according to different contextual configurations, as well as clarifying rhetorical conventions in discourse communities of science.
The Global Survey of Scientists: encountering sexual harassment
Authors: White Susan , Ivie Rachel 
Published: July 2021

Abstract
We describe our work on The Global Survey of Scientists and examine men’s and women’s experiences with sexual harassment. We use multivariate models in our analyses to account for possible confounding variables. Our model accounts for gender, discipline, age, employment sector, geographic region, and level of human development. Taking all these factors into consideration, we find that women are 14.4 times more likely than men to indicate having personally encountered sexual harassment at school or work. We take a closer look at potential differences in discipline, employment sector, geographic region, and level of development.
Scale-bridging Microstructural Analysis – A Correlative Approach to Microstructure Quantification Combining Microscopic Images and EBSD Data
Authors: Müller M. , Britz D. , Mücklich F. 
Published: July 2021

AbstractA comprehensive description of complex material structures may require characterization using different methods and observations across several scales. This work will present a correlative approach including light optical microscopy, scanning electron microscopy and electron backscatter diffraction, enabling microstructure quantification which combines microscopic images and electron backscatter diffraction data. The parameters obtained from electron backscatter diffraction such as misorientation parameters or grain and phase boundary data are an ideal source of information, complementing microscopic images. Two case studies performed on bainitic microstructures will be presented to demonstrate practical applications of this approach.
