How well do forecast models represent observed long‐lived Rossby wave packets during southern hemisphere summer?
Authors: Pérez‐Fernández Iago , Barreiro Marcelo 
Published: May 2023

AbstractRossby wave packets (RWPs), are atmospheric perturbations linked to the occurrence of extreme weather events such as heatwaves, extratropical cyclone development and other equally destructive phenomena. Under certain circumstances, these packets can last from several days to 2–3 weeks in the atmosphere. Therefore, forecast models should be able to correctly predict their formation and development to enhance extreme weather events prediction from 10 to 30 days in advance. In this study, we assess whether the NCEP and IAP‐CAS sub‐seasonal forecast models can predict the evolution of observed RWPs that last more than 8 days (long‐lived RWPs or LLRWPs) during southern hemisphere summer. Results show that the NCEP (IAP‐CAS) model forecasts LLRWPs that appear eastward (westward) from the observed LLRWPs. Both models forecasted LLRWPs that rapidly lose energy after the 6th–7th lead day of simulation, which could limit LLRWPs prediction to the synoptic time scale. Additionally, both models better forecast LLRWPs when the packets manifest in the eastern Pacific. Southern Annular mode (SAM) and El Niño Southern‐Oscillation (ENSO) do not seem to exert a large influence in the representation of LLRWPs. Nevertheless, during the best LLRWPs forecasts, the observed circulation anomalies signal the manifestation of negative SAM events. In contrast, both forecast models struggle at forecasting LLRWPs when a blocking situation develops to the South of Australia. Lastly, an inactive Madden Julian Oscillation (MJO) seems to favor the development of accurate LLRWPs forecasts, whereas during phases 3, 5 in the NCEP model and 3, 8 for IAP‐CAS, the models struggle at forecasting LLRWPs.

AbstractZur Verbesserung der Dauerhaftigkeit bietet es sich bei einigen Bauteilen an, konventionelle Betonstahlbewehrung durch Bewehrungselemente aus faserverstärktem Kunststoff (FVK) zu ersetzen. Hierbei sind in der Vergangenheit im wesentlichen Bewehrungselemente mit Glas‐ oder Carbonfasern eingesetzt worden. An der FH Kiel wurde in den letzten zwei Jahren das Tragverhalten von Betonbauteilen mit Basaltfaserstabbewehrung untersucht und konkrete Anwendungen entwickelt. Der Beitrag fasst die Erkenntnisse zusammen.
Exposing the confounding in experimental designs to understand and evaluate them, and formulating linear mixed models for analyzing the data from a designed experiment
Authors: Brien Christopher James , Sermarini Renata Alcarde , Demétrio Clarice Garcia Borges 
Published: May 2023

AbstractComparative experiments involve the allocation of treatments to units, ideally by randomization. This necessarily confounds treatment information with unit information, which we distinguish from the other forms of information blending, in particular aliasing and marginality. We outline a factor‐allocation paradigm for describing experimental designs with the aim of (i) exhibiting the confounding in a design, using analysis‐of‐variance‐like tables, so as to understand and evaluate the design and (ii) formulating a linear mixed model based on the factor allocation that the design involves. The approach exhibits the dispersal of treatments information between units sources, allows designers a choice in the strategy that they adopt for including block‐treatment interactions, clarifies differences between experiments, accommodates systematic allocation of factors, and provides a consolidated analysis of nonorthogonal designs. It provides insights into the process of designing experiments and issues that commonly arise with designs. The paradigm has pedagogical advantages and is implemented using the R package dae.
The academic landscape of sustainability in management literature: Towards a more interdisciplinary research agenda
Authors: Vinayavekhin Sukrit , Li Feng , Banerjee Aneesh , Caputo Andrea 
Published: May 2023

AbstractSustainability research is vast and complex, making it difficult to grasp the big picture. To help researchers understand the field better, we created a comprehensive knowledge map of sustainability in management literature by utilising citation‐based clustering and text mining techniques to analyse 25,737 sustainability‐related papers across 22 academic disciplines, as categorised by the Chartered Association of Business Schools (ABS)'s Academic Journal Guide. We identify 23 research streams, with the top three being corporate social responsibility, operations & supply chain and tourism. Each research stream has varying degrees of definition coverage, levels of analysis, levels of interdisciplinarity and connections to the 17 United Nations' Sustainable Development Goals (SDGs). Goals #9, #10, #12 and #13 receive more attention than Goals #3, #14 and #15. Our findings suggest a need for more interdisciplinary collaboration between researchers, and we propose four research directions to achieve this.
Human‐virtual crowd interaction: Towards understanding the effects of crowd avoidance proximity in an immersive virtual environment
Authors: Trivedi Hritik , Mousas Christos 
Published: May 2023

SummaryThis paper focuses on understanding how study participants interact and perceive a virtual crowd in an immersive virtual environment. Specifically, our within‐group exploratory study investigated how avoidance proximity variations (i.e., low, medium, and high avoidance proximity [defined as avoidance radius]) assigned to crowd agents impacted participants' interaction with the virtual crowd. During the study, we instructed our participants to walk in a virtual environment. At the same time, we had a virtual crowd scripted to walk toward the start position of the participant following a straight path. During the participants' walking task, we collected movement data (i.e., trajectory length and completion time) and immediately after each experimental condition, we asked participants to self‐report their experience (i.e., co‐presence, behavioral independence, crowd realism, crowd interaction realism, perceived politeness, and emotional reactivity). Based on the collected data, we found that when we exposed our participants to the high avoidance proximity condition, they: (1) followed longer paths, (2) spent more time reaching the target goal, (3) rated the virtual crowd less polite, (4) rated the virtual crowd and their interaction with the virtual crowd less realistic, (5) rated the behavior independence of the virtual crowd lower, and (6) self‐reported higher emotional reactivity. We discuss our findings and suggestions for further research on human‐virtual crowd interaction.

Published: May 2023

AbstractThis work describes a unique and environmentally friendly approach for creating three‐dimensional (3D) organic‐inorganic flower shaped hybrid nanostructures called “nanoflower (NF)” by using Umbilicaria decussate (U. decussate) extract and copper ions (Cu2+). U. decussate species were collected from certain place in Antarctic and Turkey and extraction of each species were completed in methanol and water. The U. decussate extracts were used as organic components and Cu2+ acted as inorganic components for formation of U. decussate extracts based hybrid NFs. We rationally used these NFs as novel nanobiocatalyst and antimicrobial agents. These NFs exhibited peroxidase mimic, dye degradation and antimicrobial properties. The NFs were characterized with various techniques. For instance, the morphologies of the NFs were monitored by scanning electron microscope (SEM), presence of elements in the NFs were presented using Energy Dispersive X‐Ray Analysis (EDX). Fourier‐transform infrared spectroscopy (FT‐IR) was used to elucidate corresponding bending and stretching of bonds in the NFs. The NFs acted as effective Fenton agents in the presence of hydrogen peroxide, and we demonstrated their peroxidase‐like activity against guaiacol, dye degradation property towards malachite green and antimicrobial activity for Aeromonas hydrophila, Aeromonas sobria, Escherichia coli, Salmonella enterica and Staphylococcus aureus.
Studies of NO Reduction with Ammonia Over Copper Species Deposited on MCM‐41 Nanospheres ‐ Experimental Evidence of Reaction Mechanism
Authors: Jankowska Aleksandra , Bobowska Aleksandra , Gil Barbara , Chmielarz Lucjan 
Published: May 2023

AbstractNanospheres of MCM‐41 were modified with copper by template ion‐exchange (TIE) and cocondensation methods. In the samples modified by TIE, dispersion of copper was significantly improved by their post‐treatment in ammonia solutions. Highly dispersed copper species were significantly more active in low‐temperature NH3‐SCR than CuO aggregates. Copper dispersed on silica MCM‐41 catalytically operated at lower temperatures than copper deposited on silica‐alumina MCM‐41. The studies of reaction mechanism showed that ammonia and NOx species compete for these same adsorption sites (copper cations) and NH3 can remove NOx from such sites. Dispersed copper species are more active in NO to NO2 oxidation than CuO aggregates. Accumulation of oxidised NOx species in the absence of ammonia was more privileged on CuO aggregates. It is postulated that the main reaction pathway in the low‐temperature range is reaction of ammonia bounded to copper with NOx from gas phase or loosely bounded to the catalyst surface.

AbstractBackgroundPsychological distress is associated with worsening symptoms during the active treatment period and lower quality of life in women with early‐stage breast cancer. Many studies have indicated risk for heightened psychological distress across the breast cancer trajectory.PurposeThe aim of this review is to examine the literature for instruments used to measure psychological distress among women with breast cancer during chemotherapy.MethodsThis study used the Arksey and O’Malley framework of scoping reviews. Two databases, PubMed & CINAHL, were searched for peer‐reviewed original articles that were published within the last ten years, included participants with a diagnosis of breast cancer stages I to III, and receiving chemotherapy, English text articles, and studies that report psychological distress measures.FindingsThe initial screening yielded 529 relevant studies. After applying the exclusion criteria, a total of 17 studies concerning the assessment of psychological distress during chemotherapy were retained for the analysis of variables and measures of psychological distress. The instruments used to measure psychological distress varied, with a total of 21 measures. The most frequently utilized measure was the Hospital Anxiety and Depression Scale (n = 5), followed by the Impact of Event Scale (n = 2), the Distress Thermometer (n = 2), and the Perceived Stress Scale (n = 2).ConclusionThis review identified the gaps related to inconsistencies in the operationalization and instruments used to measure psychological distress among breast cancer survivors during chemotherapy. Standardization of measures assessing psychological distress, along with conceptual clarity, is essential for measuring distress in research and clinical practice.
Photoelectrochemical Reactive Oxygen Species Generation for Organic Conversion
Authors: Miao Jiaming , Guo Hu , Zhang Kan 
Published: May 2023

AbstractPhotoelectrochemical (PEC) cells, which integrate the advantages of electrochemistry and photochemistry, are making a great contribution to the synthesis of high‐value‐added chemicals and biomass reforming. However, oxidation of organic substrates by directly capturing photo‐generated holes at the solid/liquid interface faces the challenge of inefficient mass transfer and low selectivity. Recently, reactive oxygen species (ROSs) mediated PEC organic conversion has attracted much attention due to its high selectivity, homogeneous nature and controllability. This Concept will review representative applications of PEC organic conversion mediated by ROSs, and put forward perspectives and outlooks for the generation of ROSs.
Fgf, Hh, and pax2a differentially regulate expression of pax5 and pou3f3b in vestibular and auditory maculae in the zebrafish otic vesicle
Authors: Tan Amy L. , Christensen Sydney E. , Baker Allison K. , Riley Bruce B. 
Published: May 2023

AbstractBackgroundThe vertebrate inner ear contains distinct sensory epithelia specialized for auditory or vestibular function. In zebrafish, the first sensory epithelia form at opposite ends of the otic vesicle and are functionally distinct: the anterior utricular macula is essential for vestibular function whereas the posterior saccular macula is critical for hearing. Mechanisms distinguishing these maculae are not clear. Here, we examined the effects of manipulating Fgf or Hh on expression of pax5 and pou3f3b, unique markers of utricular and saccular identity. We also examined the roles of pax2a and atoh1a/b, early regulators of sensory specification.Resultsfgf3 and fgf8a were uniquely required for pax5 and pou3f3b, respectively. Elevating Fgf or blocking Hh expanded expression of pax5 but repressed pou3f3b, while blocking Fgf had the opposite effect. Blocking sensory specification did not affect pax5 or pou3f3b, but both markers were lost in pax2a−/− mutants. Maintenance of pax2a expression requires Fgf, Hh and Pax2a itself.ConclusionSpecification of utricular identity requires high Fgf and is repressed by Hh, whereas saccular identity requires Hh plus low Fgf. pax2a acts downstream of Fgf and Hh to maintain both fates. Comparison with mouse suggests this may reflect a broadly conserved developmental mechanism.

AbstractVery little is known about factors determining the assemblage structure of megadiverse polyphagous‐herbivore scarab chafers in the tropics (Coleoptera: Scarabaeidae). Here, we examined the composition of Sri Lankan chafer assemblages and investigated whether it is influenced more by the general ecoclimatic situation, macrohabitat, or indetermined stochastic biotic and abiotic factors of each locality. We also explored the influence of the latter on separate lineages and general body size. Based on dedicated field surveys conducted during the dry and wet seasons, we examined 4847 chafer individuals of 105 species sampled using multiple UV‐light traps in 11 localities covering different forest types and altitudinal zones. Assemblages were assessed for compositional similarity, species diversity, and abundance within four major eco‐spatial partitions: forest types, elevational zones, localities, and macrohabitats. Our results revealed that assemblages were shaped mainly by locality stochastics (i.e., multi‐factor ensemble of all biotic and abiotic environmental conditions at local scale), and to a minor extent by ecoclimatic conditions. Macrohabitat had little effect on the assemblage composition. This was true for the entire chafer assemblage as well as for all single lineages or different body size classes. However, in medium and large species the contrasts between localities were less pronounced, which was not the case for individual lineages of the assemblage. Contrasts of assemblage similarity between localities were much more evident than those for forest types and elevation zones. Significant correlation between species composition and geographic distance was found only for the assemblage of small‐bodied specimens. Seasonal change (dry–wet) in species composition was minor and only measurable in a few localities. The strong turnover between examined localities corroborates with the high degree of endemism in many phytophagous chafers, particularly in Sericini. Connected with their hypothetic poor habitat specificity and polyphagy, this might also explain why so many chafer crop pests in the Asian tropics are endemics.

AbstractBackground and AimsUpper limb disabilities are one of the most common disabilities among different groups of people who always need rehabilitation. One of the important methods in helping to carry out efficient rehabilitation processes and exercises is the use of games. The aim of this study is to identify the parameters necessary to design a successful rehabilitation game and the outcomes of using these games in upper limb disabilities rehabilitation.MethodsThis scoping review was conducted by searching the Web of Science, PubMed, and Scopus. The eligibility criteria were: any form of game‐based upper limb rehabilitation, published in a peer‐reviewed journal, published in English, and not include articles that did not focus upper limb disabilities rehabilitation games, review, meta‐analysis, or conference papers. Analysis of collected data was done using descriptive statistics (frequency and percentage).ResultsThe search strategy retrieved 537 relevant articles. Finally, after removing irrelevant and repetitive articles, 21 articles were included in this study. Among the six categories of diseases or complications of upper limb disabilities, games were mostly designed for stroke patients. Smart wearables, robots and telerehabilitation were three technologies that were used for rehabilitation along with games. Sports and shooters were the most used games for upper limb disability rehabilitation. Among 99 necessary parameters for designing and implementing a successful rehabilitation game in ten categories. “Increasing the patient's motivation to perform rehabilitation exercises”, “Game difficulty levels”, “Enjoying and the attractiveness of the game for patients”, and “Providing positive or negative audiovisual feedback” were the most important parameters. “Improvement in musculoskeletal performance” and “Increasing users' enjoyment/joy of therapeutic exercises and their motivation to perform these exercises” were the most important positive outcomes, and “Mild discomfort such as nausea and dizziness when using games” was the only negative outcome.ConclusionsThe successful design of a game according to the parameters identified in the present study can lead to an increase in the positive outcomes of using games in the rehabilitation of disabilities. The study results indicate that upper limb therapeutic exercise augmented with virtual reality games may be highly effective in enhancing motor rehabilitation outcomes.
Public health concerns surrounding the cVDPV2 outbreak in Africa: Strategies for prevention and control with a special focus on Nigeria
Authors: Adesola Ridwan O. , Idris Ibrahim , Opuni Emmanuel 
Published: May 2023

AbstractBackground and AimPoliovirus is a global health issue that affects children in different parts of the world. Despite the efforts of national, international, and nongovernmental organizations to eradicate the disease, it is re‐emerging in Africa due to poor sanitation, vaccine hesitancy, new ways of transmission, and poor surveillance among others. Circulating vaccine‐derived poliovirus type 2 (cVDPV2) is a major step in eradicating poliovirus and preventing outbreaks in developing countries. Strengthening African healthcare systems, increasing surveillance, hygiene and sanitation, and proper mass vaccination to achieve herd immunity are required in the fight against polio disease. This paper discusses the outbreak of cVDPV2, public health challenges, and recommendations in Africa with a special emphasis on Nigeria.MethodsWe searched for articles documenting the incidence of cVDPV2 in Nigeria and other African countries on Pubmed, Google Scholar, and Scopus.ResultsA total of 68 distinct cVDPV2 genetic emergences were found across 34 nations between April 2016 to December 2020, and in Nigeria, three cVDPV2 emergences were found. Also, 1596 instances of acute flaccid paralysis linked to cVDPV2 outbreaks were reported in four areas of the World Health Organization where Africa contributed 962 cases out of 1596 cases. Available data indicate that Africa has the most cVDPV2 cases and is associated with various challenges like the unidentified virus source, poor sanitation system, and inability to achieve herd immunity of the cVDPV2 vaccine.ConclusionCollaborative efforts of stakeholders are crucial in combating infectious diseases, especially those transmitted via environments such as water and air, like poliovirus. Therefore, a collaboration between environmental health workers, veterinarians, community health workers, laboratory scientists, policymakers, and other professionals is required.
Relating relational networks: An initial experimental analysis

Published: May 2023

AbstractStudying relating of relational networks is a complex and challenging task. The main objective of the present study was to demonstrate relating within and across relational networks based on same/opposite and bigger/smaller contextual cues and establish antecedent control. After nonarbitrary pretraining of the contextual cues, two nonsense stimulus classes were established based on comparative relations. Participants were trained to select stimuli from an array of options based on a symbolic rule that established a relation between two stimuli: one of Network 1 and one of Network 2. Training involved relating Network 1 to Network 2, and testing assessed relating Network 2 to Network 1. Seven of eight participants reached the mastery criterion in training and responded accordingly in test. In a final stage, reinforcing and punishing consequences were varied systematically in the presence of two novel stimuli and antecedent control was observed for all 7 participants. Experiment 2 replicated the results of Experiment 1 but using contextual cues taken from natural language, and Experiment 3 sought to understand the effects of pretraining relational responding using natural language. The mastery criteria were reached by four of seven participants in Experiment 2 and by all eight participants in Experiment 3. Future studies could develop and refine the methods employed here in analyzing the relating of relational networks, thus allowing for an increasingly sophisticated behavior‐analytic account of human language and cognition.

Published: May 2023

AbstractWe study the two‐dimensional stochastic time‐fractional Sine–Gordon equation (2D ST‐FS‐G) and provide a solution for it. We use the new clique polynomial method to obtain a numerical solution to the 2D TFS‐G equation. In this technique, the clique polynomial is considered as a basic function for operational matrices. By converting the 2D ST‐FS‐G equation to algebraic equations, a solution is obtained for the desired equation, which clearly shows that this approach is suitable and accurate for dealing with the equation. We further present the error boundary for the obtained approximation of the desired three‐variable function based on the clique polynomial. Finally, we compare some numerical results obtained with the exact ones by a few practical examples.
