Authors: Zaman Wajid , Ullah Fazal , Park SeonJoo 
Published: April 2023

AbstractThe foliar epidermal anatomical characteristics of the two endemic Apiaceae species of Korea Bupleurum latissimum Nakai and Dystaenia takesimana (Nakai) Kitag. were investigated. The taxonomically important characteristics of these two species were identified and described to help understand their classical taxonomy. Scanning electron microscopy (SEM) was used to observe the anatomical characteristics of the studied species in detail. The comparative foliar epidermal anatomical characteristics were observed in the present research for the two‐endemic species. Some of the most important foliar epidermal anatomical characteristics were observed to distinguish them, including the epidermal cell shape and size, stomata type, and trichomes shape and size. SEM provided sufficient evidence to distinguish the study species. The foliar epidermal anatomical characteristics provide sufficient information to differentiate these two species from their closely related taxa.Research Highlights
Apiaceae species endemic to Ulleungdo and Dokdo Islands exhibit unique foliar epidermal anatomical characteristics that can be used for taxonomic identification and classification.
This study contributes to the documentation of the plant diversity of Ulleungdo and Dokdo Islands, and highlights the need for further research on the biogeography and conservation of these endemic plant species.

Published: April 2023

AbstractBackgroundDetection of appropriate indicators is valuable for preventing incidental osteoporotic fractures. We statistically evaluated the significance of serum cystatin C‐to‐creatinine ratio (CysC/Cr) as a surrogate marker for incident major osteoporotic fractures (MOF) prediction.MethodsEligible patients with simultaneous measurement of CysC/Cr and bone mineral density in the lumbar spine and proximal femur were selected, and their fracture histories until 5 years after baseline were observed in the retrospective area cohort data. Patients who were followed up until termination or the first osteoporotic fracture were included, and loss of follow‐up or death was excluded. Candidate risk factors for osteoporotic fractures were tested for risk ratios using a cox regression analysis. Receiver operating characteristic tests were performed on factors with significantly higher risk ratios and evaluated with Kaplan‐Meier survival analysis to determine the hazard ratios of the factors.ResultsA total of 175 patients of whom 28 had incident MOF, 38 men, and 137 women, were enrolled. The mean age was 70.2 years. A significantly higher risk ratio was shown in the presence of prevalent MOF, hyper fall‐ability, lifestyle‐related diseases, chronic kidney diseases ≥ Grade3a, and higher CysC/Cr. All parameters had cutoff indices and showed significantly higher hazard ratios.ConclusionsThese results suggested that CysC/Cr may be a predictive marker of incident osteoporotic fractures. It might work as a screening tool for MOF risk.
Event‐based extreme precipitation variability analysis over a part of the Hindu Kush Himalayan region
Authors: Malla Mani Kanta , Arya Dhyan Singh 
Published: April 2023

AbstractExtreme precipitation is a primary driver of flood hazards causing damage to humans and infrastructure. Analysis of extreme precipitation without considering temporally compounding events underestimates the severity of the hazard. Especially mountainous regions such as the Hindu Kush Himalayan region are highly vulnerable to multiday extreme precipitation events. However, analysis of such events and their time distribution patterns are still unknown, and a comprehensive assessment is needed. To this, the concept of event‐based extreme precipitation, which accounts for the preceding and succeeding precipitation, is employed for the Upper Indus basin using three reference gridded datasets, namely, Indian Meteorological Department (IMD), Multi‐Source Weighted Ensemble Precipitation (MSWEP) and Himalayan Adaption, Water and Resilience (HI‐AWARE). Four different types of time distribution patterns were identified based on the occurrence of extreme precipitation during an event. We identified that the time distribution pattern with the peak on the right side is predominant among the four types. Subsequently, trend analysis on the characteristics, namely amount, frequency, duration and concentration ratio for all four events, display negative trends with IMD and MSWEP datasets, whereas HI‐AWARE displays positive trends in the northwestern part of the catchment. Further, the 100‐year return level of the amount of multiday extreme precipitation is computed along with the traditional method of single‐day extremes considering nonstationarity. The differences between the return values obtained using the traditional method and the event‐based extreme precipitation concept were distinct and substantial (>50 mm for three datasets). The findings clearly show that the analysis of multiday events is much more essential than single‐day extreme events, particularly for events like floods. Moreover, the results of the study were found to be conflicting among reference datasets, demonstrating the importance of identifying the suitability of reference datasets in extreme event analysis.

Published: April 2023

AbstractThe present study focuses on the growth and detailed investigation of temperature‐dependent phonon properties of BixRe1−xSe2 (x = 0.0,0.1,0.5) ternary alloys. Here, we have grown BixRe1−xSe2 (x = 0.0,0.1,0.5) ternary alloy crystals by the direct vapour transport (DVT) method and achieved high‐quality single crystals. The surface morphological validations of the crystals were determined by HRTEM analysis. The crystallinity of the samples was identified from the SAED pattern. The structural analysis was carried out with aid of powder X‐ray diffraction. The shift of the dominant peak towards higher 2θ shows the substitution of the Bi atom at Re sites. Further Raman spectra of the DVT‐grown crystals were recorded in the temperature range of 93 to 333 K. The temperature‐dependent Raman spectroscopy of the sample showed a steady redshift and peak broadening of Eg and two Ag peaks as the temperature varies from 93 to 333 K. Quantitative parameters such as peak position at 0 K (ω0) and first‐order temperature coefficient (χ) for Raman modes (Eg and two Ag) are calculated. The results were compared with theoretical models of the three‐ and four‐phonon processes and it was found that the three‐phonon process was responsible for the redshift in this case.

Mixtures of Acid‐ and Base‐Functionalized Microparticles for One‐Pot Cascade Reaction
Authors: Chen Chen , Wong Chin Ken , Gröschel André H. 
Published: April 2023

AbstractThis study reports on the synthesis of surface‐protected acid and base microparticles via surfactant‐free emulsion polymerization. The protective layer allows to form particle mixtures with both colloidal catalysts that show excellent performance in a well‐established model cascade reaction involving an acid‐catalyzed deacetalization and a subsequent base‐catalyzed Knoevenagel condensation. Compared to nanoreactors that contain both catalysts, the colloidal mixture shows comparable reaction kinetics despite the local separation of both catalysts onto separate particles. Since the synthesis of individual microparticles requires less steps, is scalable, and more versatile in terms of catalyst variation, colloidal mixtures are certainly an alternative to multifunctional nanoreactors, making them attractive for practical applications.

Published: April 2023

AbstractAs a germane marketing tool, advertising has shrift to social media platform. What role of social media advertising plays in the omni‐channel supply chain needs to conduct a thorough examination. Therefore, this paper investigates a model in which a manufacturer supplies product to two competitive retailers to compare channel payoffs when considering social media advertising in four different scenarios. Specifically, the demand function fully considers the impact of exponential propagation of social media advertising. The conclusions could provide decision basis for enterprises and platform managers on social media channel selection, social media advertising pricing and cooperation form selection.

Published: April 2023

ScopeContinuous ultraviolet (UV) exposure causes skin photoaging, wrinkle formation, and skin barrier damage. In this study, the protective effect of mixed probiotics (MP) against photoaging in UVB‐irradiated Hs68 fibroblasts and SKH‐1 hairless mice is investigated.Methods and resultsThe mice are irradiated with UVB for 8 weeks to induce photoaging, and MP (15 and 50 mg day−1) is orally administered once a day. Skin parameters are measured in the dorsal skin and wrinkle formation factors are analyzed in skin replicas. To evaluate the mitogen‐activated protein kinase (MAPK) signaling pathway, western blotting and qRT‐PCR are performed. MP (50 mg day−1) significantly improves skin moisture, transepidermal water loss, erythema, and skin thickness. MP also effectively suppresses wrinkle formation by regulating the transcriptional expression of matrix metalloproteinases (MMPs) and tissue inhibitors of MMPs. MP also reduces inflammatory cytokine levels and phosphorylation of extracellular signaling regulatory kinase, Jun N‐terminal kinase, and p38 protein. Furthermore, the intestinal microbiome of the MP groups is significantly different compared with that of the UVB group, and the relative abundance of Lactobacillus and Akkermansia is significantly increased.ConclusionCollectively, these findings suggest that MP modulates the gut microbiome and ameliorates UVB‐induced photoaging by downregulating the MAPK pathway.

An asymptotic preserving scheme for the shallow‐water equations with Manning friction using viscous correction of the HLL scheme
Authors: Bulteau Solène , Berthon Christophe , Bessemoulin‐Chatard Marianne 
Published: April 2023

AbstractThe aim of this article is to propose a numerical scheme for the shallow‐water equations with a Manning's friction source term able to preserve the diffusive regime, namely the behavior of the solutions in long time and stiff friction limit. Because of the non‐usual rescaling of the friction parameter, a strongly nonlinear derivative operator is involved in the diffusive limit and the development of a numerical scheme possessing this property is not straightforward. The scheme presented here is based on a perturbed HLL scheme with additional viscous terms.

Published: April 2023

AbstractIn this paper, a hybrid numerical scheme based on combining exponential time differencing (ETD) and local radial basis function collocation method was constructed. Model problems with different boundary conditions were considered, and the resulting linear system was carefully analyzed. The relation between the number of points employed in the local radial basis function collocation method and the condition number of the coefficient matrix was given. For application, three typical differential equations were investigated, that is, the Allen–Cahn equation for checking the maximum‐preserving property, the combustion equation for checking the monotonicity‐preserving property, and the Gray–Scott system for checking the robustness of the proposed scheme. Numerical examples show the effectiveness of the proposed method.

Published: April 2023

AbstractObjectiveFrom diagnosis and beyond, a paediatric brain tumour and its treatment impact the child and their family in a myriad of ways. While it is considered best practice to offer ongoing psychosocial support for all family members, there is little scholarly investigation of both families' experiences and the practical implications of offering such care. We aimed to explore families' experiences of paediatric brain tumour and their associated psychosocial health service needs.MethodsFamilies receiving care at the Queensland Children's Hospital in Brisbane, Australia, for a child (0–18 years) who had been diagnosed with a brain tumour between 2019 and 2022 were invited to be interviewed about their experiences. Using qualitative description, we analysed these interviews to identify families' unmet psychosocial health service needs and their suggestions for improvement.ResultsTwenty‐three clinically and socially diverse families were represented. While parents/carers expressed gratitude for the care their child had received, most also described unmet needs for the broader family. We identified three primary needs to be addressed: (1) parents want accessible psychological/emotional support for themselves; (2) parents/carers want additional guidance to navigate the hospital setting to reduce uncertainty and loss of control; and (3) parents want support to minimise treatment‐associated trauma for their child.ConclusionsOur findings evidence the need for improved family‐centred psychosocial care within paediatric brain tumour care in Queensland, Australia. We propose a counselling and care coordination intervention to support parents/carers to care for themselves, their child, and their family through an extremely challenging experience.

AbstractBackgroundThe COVID‐19 pandemic has spread across the world, leading to government measures associated with a negative impact on mental health. The aim of this study was to evaluate the impact of the pandemic on depression, anxiety and resilience in Dutch people with cystic fibrosis (PwCF) or primary ciliary dyskinesia (PwPCD) and their caregivers.MethodsAdolescents (12–17 years) and caregivers of children (0–17 years) with CF, and adolescents, adults and caregivers of children with PCD completed questionnaires on depression, anxiety and resilience between September 2020 and February 2021. The psychosocial impact of COVID‐19 was measured by the Exposure and Family Impact Survey (CEFIS) Part 2. Mixed model analyses compared depression and anxiety results to participants' prepandemic scores.ResultsOne hundred ten participants (10 PwCF, 31 PwPCD, 52 CF caregivers, 17 PCD caregivers) completed questionnaires during the pandemic. Prepandemic outcomes were available for 87 participants. The prevalence of symptoms of depression and anxiety (PHQ‐9 or GAD‐7 scores ≥5) in PwCF and PwPCD and their caregivers before and during the pandemic was high, with an increase in depression in PwCF (2.75; 95% confidence interval: 0.82–4.68) and increase in anxiety in CF caregivers (1.03; 0.09–1.96) during the pandemic. Resilience was within the normal range for all groups, CEFIS scores corresponded to a low to normal impact.ConclusionPwCF and PwPCD and their caregivers were at risk of elevated depression and anxiety symptoms both before and during the pandemic, which emphasizes the importance of mental health screening and psychological care in CF and PCD.

AbstractBackgroundRadon may have a role in obstructive lung disease outside its known carcinogenicity. Little is known about radon's effects on asthma morbidity.ObjectiveTo determine the effect of radon on fractional exhaled nitric oxide (FENO), asthma symptom‐days, and lung function in inner‐city asthmatic school children.MethodsTwo hundred ninety‐nine school‐aged asthmatic children enrolled in the School Inner‐City Asthma Study (SICAS‐1) were followed. One and two‐month averaged radon was assessed using a spatiotemporal model predicting zip code‐specific monthly exposures. FENO and spirometry were measured twice during the academic year. Asthma symptoms were assessed four times during the academic year. The interaction between indoor radon exposure (Bq/m3) and seasonality predicting log‐transformed FENO, forced expiratory volume in 1 s (FEV1) % predicted, forced vital capacity (FVC) % predicted, FEV1/FVC, and asthma symptom‐days was evaluated.ResultsParticipants with high radon exposure had greater change in FENO from warm to cold periods compared to low radon exposure (interaction p = 0.0013). Participants with >50th percentile radon exposure experience significant FENO increase from warm to cold weather ( = 0.29 [95% confidence interval [CI]: 0.04–0.54], p = 0.0240). We report a positive association between radon 1‐month moving average (incidence rate ratio [IRR] = 1.01, p = 0.0273) and 2‐month moving average (IRR = 1.01, p = 0.0286) with maximum asthma symptom‐days (n = 299, obs = 1167).ConclusionsIn asthmatic children, radon may be associated with increased asthma morbidity, suggesting radon may be a modifiable environmental risk factor for airway inflammation.

Regional collaboration for the sustainable development goals: Experiences from developing a multi‐actor platform in Sweden
Authors: Krantz Venus , Gustafsson Sara 
Published: April 2023

AbstractThe 2030 Agenda and its integrative and indivisible sustainable development goals (SDGs) challenge traditional ways of governing. Hence, collaboration across sectors, actors, and levels is fundamental in SDG localisation, where subnational levels (actors at regional and local levels) play key roles in forwarding societal transformation. The paper sheds light on the complexity of collaboration by exploring the early stages of developing multi‐actor collaboration for SDG implementation at a county level in Sweden. The analyses depart from interviews and observations. One of the main conclusions is that it is important to discuss the involved organisations' understanding and ambitions more in‐depth early on in such collaboration processes. To be able to do so, the actors need to have the capacity to see beyond their traditional roles. Moreover, the study indicates that leadership is essential in this context, but this leadership needs to be based on neutrality, which, in practise, is a challenge.
The four main elements of dynamic complexity
Authors: Yasarcan Hakan 
Published: April 2023

AbstractAccumulation processes, feedback loops, nonlinearities, and delays are the four main elements of dynamic complexity. Knowing about and understanding these elements is necessary in conceptualizing and constructing dynamic feedback models. Therefore, the elements are major topics when teaching system dynamics. This short note aims to explain the relations of these elements with each other in the hope of providing a perspective that can help improve the understanding of students of system dynamics. We also suggest an order of presentation of these elements in teaching based on the relations between them. © 2023 System Dynamics Society.
