Published: August 2022

AbstractIntroductionDental implant abutments play an important role in the health and aesthetics of soft and hard tissues around implants.PurposeTo compare mechanical properties and marginal fit of prefabricated and customized dental implant abutments and provide references to evaluate the relationship between abutment choice and clinical indications.MethodsTitanium abutments were randomly divided into prefabricated and customized abutments. Static and dynamic loads were applied according to ISO14801:2016. Mechanical properties, including fracture strength, fatigue strength, rotational torque value, and torque loss rate, were measured. The biological properties of the implant abutments were assessed using an internal marginal fit. The samples were sliced, and the internal marginal fit was examined using a scanning electron microscope before and after cyclic loading. The length of the tight contact was calculated at the level of the conical connection, lower internal connection, and screw threads. Microleakage was evaluated by immersing the samples in 1% methylene blue and measuring the absorbance.ResultsThe fracture strengths of the prefabricated abutments were greater than those of the customized abutments before and after cyclic loading. The average fatigue strengths of the prefabricated and customized abutments were 350 and 300 N, respectively. The removal torque loss of the customized abutments was significantly greater than that of the prefabricated abutments. Significant differences were found in conical connection before loading, while the screw threads showed substantial differences between the two groups after loading. Microleakage in the customized abutments was significantly higher than that in the prefabricated abutments before and after loading.ConclusionsPrefabricated abutments showed superior mechanical and biological properties compared with customized abutments in vitro, suggesting a greater risk of mechanical and biological complications occurring with the use of customized abutments. This study provides a reference for the clinical selection of implant abutments.
Recommendation system using a deep learning and graph analysis approach

Published: August 2022

AbstractWhen a user connects to the Internet to fulfill his needs, he often encounters a huge amount of related information. Recommender systems are the techniques for massively filtering information and offering the items that users find them satisfying and interesting. The advances in machine learning methods, especially deep learning, have led to great achievements in recommender systems, although these systems still suffer from challenges such as cold‐start and sparsity problems. To solve these problems, context information such as user communication network is usually used. In this article, we have proposed a novel recommendation method based on matrix factorization and graph analysis methods, namely Louvain for community detection and HITS for finding the most important node within the trust network. In addition, we leverage deep autoencoders to initialize users and items latent factors, and the Node2vec deep embedding method gathers users' latent factors from the user trust graph. The proposed method is implemented on Ciao and Epinions standard datasets. The experimental results and comparisons demonstrate that the proposed approach is superior to the existing state‐of‐the‐art recommendation methods. Our approach outperforms other comparative methods and achieves great improvements, that is, 15.56% RMSE improvement for Epinions and 18.41% RMSE improvement for Ciao.

AbstractObjectivesHypothalamic dysfunction leads to glucose metabolic imbalance; however, the mechanisms still need clarification. Our current study was to explore the role of hypothalamicHnscrin glucose metabolism.Materials and MethodsUsingHnscrknockout or htNSC‐specificHnscroverexpression mice, we evaluated the effects ofHnscron glucose metabolism through GTTs, ITTs, serum indicator measurements, etc. Immunofluorescence staining and Western blotting were performed to test inflammation levels and insulin signalling in hypothalamus. Conditioned medium intervene were used to investigate the effects of htNSCs on neuronal cell line. We also detected the glucose metabolism of mice with htNSCs implantation.ResultsHnscrexpression decreased in the hypothalamus after high‐fat diet feed.Hnscr‐null mice displayed aggravated systematic insulin resistance, while mice with htNSC‐specificHnscroverexpression had the opposite phenotype. Notably,Hnscr‐null mice had increased NF‐κB signal in htNSCs, along with enhanced inflammation and damaged insulin signal in neurons located in arcuate nucleus of hypothalamus. The secretions, including sEVs, ofHnscr‐deficient htNSCs mediated the detrimental effects on the CNS cell line. Locally implantation withHnscr‐depleted htNSCs disrupted glucose homeostasis.ConclusionsThis study demonstrated that decreased Hnscr in htNSCs led to systematic glucose imbalance through activating NF‐κB signal and dampening insulin signal in hypothalamic neurons.
Aneurysmal bone cysts as a diagnostic consideration in juvenile patients: Considerations from humans and animals
Authors: Stewart Holly L. 
Published: August 2022

SummaryAneurysmal bone cysts are benign, locally aggressive bone lesions observed in both human and veterinary species, most frequently in a juvenile population. These lesions are now accepted to have a neoplastic aetiology, cause local pain and may result in secondary pathologic fractures. Advanced imaging modalities, such as computed tomography and magnetic resonance imaging, are helpful in characterisation and diagnosis; however, biopsy and histopathology are required to definitively diagnose these lesions. Surgical excision of aneurysmal bone cysts is the most frequently reported treatment method; however, numerous other surgical and medical management strategies are reported across the human and veterinary literature. The limited number of published equine studies on aneurysmal bone cysts suggests that horses may have unique considerations in terms of location and associated morbidity that warrant further discussion.
An analysis and prediction model based on complex network time series
Authors: Zhang Wenting 
Published: August 2022

AbstractAt present, mainstream research on complex network evolution involves measuring the developing characteristics of network structure at the macro level. Few studies have focused on the internal mechanism of network structure change and the prediction of network structure evolution at the micro‐level. However, for some special complex network time series, the traditional analysis and research methods at the macro level are invalid, and the micro‐level analysis method needs to be adopted. Based on the evolution characteristics of nodes and edges in complex networks, this paper constructs a time series network analysis and prediction algorithm to explore the structural evolution trends of complex network time series and make a prediction. Based on the enterprise supply–demand relationship data, this paper constructs the enterprise supply–demand network time series. Then, we use the method proposed in this paper to analyse and predict the complex network time series and verify the rationality and feasibility of the proposed method.
Contrasting temperature effects on the velocity of early‐ versus late‐stage vegetation green‐up in the Northern Hemisphere
Authors: Hong Songbai , Zhang Yichen , Yao Yitong , Meng Fandong , Zhao Qian , Zhang Yao 
Published: August 2022

AbstractGlobal vegetation greening has been widely confirmed in previous studies, yet the changes in the velocity of green‐up in each month of green‐up period (GUP) remains unclear. Here, we defined the velocity of vegetation green‐up as VNDVI (the monthly increase of Normalized Difference Vegetation Index [NDVI] during GUP) and further explored its response to climate change in middle‐high‐latitude Northern Hemisphere. We found that in early GUP, VNDVI generally showed positive trends from 1982 to 2015, whereas in late GUP, it showed negative trends in most areas. Such contrasting trends were mainly due to a positive temperature effect on VNDVI in early GUP, but this effect turned negative in late GUP. The increase of soil moisture also in part explained the accelerated vegetation green‐up, especially in the arid and semi‐arid ecosystems of inland areas. Our analyses also indicate that the first month of the GUP was the key stage impacting vegetation greenness in summer. Future warming may continuously speed up the early growth of vegetation, altering the seasonal trajectory of vegetation and its feedbacks to the Earth system.

Published: August 2022

AbstractThe nuclear envelope (NE) provides a permeable barrier that separates the eukaryotic genome from the cytoplasm. NE is a double membrane composed of inner and outer nuclear membranes. Ish1 is a stress‐responsive NE protein in the fission yeast, Schizosaccharomyces pombe. Les1 is another NE protein that shares several similar domains with Ish1, but the relationship between them remains unknown. In this study, using fluorescence and electron microscopy, we found that most regions of these proteins were localized within the NE lumen. We also found that Ish1 interacted with Les1 via its C‐terminal region in the NE lumen and that the NE localization of Ish1 depended on the C‐terminal region of Les1. Ish1 and Les1 were co‐localized at the NE in interphase cells, but when the nucleus divided at the end of mitosis (closed mitosis), they showed distinguishable localization at the midzone membrane domain. These results suggest the regulated interaction between Ish1 and Les1 in the NE lumen, although this interaction does not appear to be essential for cell survival.
A COMPARISON OF LIVING STANDARDS ACROSS THE UNITED STATES OF AMERICA
Authors: Falcettoni Elena , Nygaard Vegard M. 
Published: August 2022

AbstractWe use an expected utility model to examine how living standards, or welfare, vary across the United States and how each state's welfare has evolved over time, accounting for cross‐state variations in mortality, consumption, education, leisure, and inequality. We find considerable cross‐state heterogeneity in welfare levels. This is robust to allowing for endogenous interstate migration and to computing welfare conditional on education, gender, and race. Although states experienced heterogeneous welfare growth rates between 1999 and 2015 (1.68–3.73% per year), there is no evidence of convergence in welfare levels, including during the subperiods preceding and following the Great Recession.
Does the emotional design of scaffolds enhance learning and motivational outcomes in game‐based learning?

Published: August 2022

AbstractBackgroundIn recent years, the importance of emotions in learning has been increasingly recognized. Applying emotional design to induce positive emotions has been considered a means to enhance the instructional effectiveness of digital learning environments. However, only a few studies have examined the specific effects of emotional design in game‐based learning.ObjectivesThis quasi‐experimental study utilized a value‐added research approach to investigate whether emotional design applied to scaffolding in a game‐based learning environment improves learning and motivational outcomes more than emotionally neutral scaffolding.MethodsA total of 138 participants, mean age of 11.5 (SD = 0.73) participated in the study. A total of 68 participants played the base version of a fraction learning game (Number Trace), where scaffolding was provided with emotionally neutral mathematical notations, and 70 participants played the value‐added version of the game using emotionally designed animated scaffolding agents. Pre‐and post‐tests were used to measure conceptual fraction knowledge and self‐reported measures of situational interest and situational self‐efficacy to evaluate motivational outcomes.Results and ConclusionsOur results indicate that the emotional design applied to scaffolds can improve the educational value of a game‐based learning environment by enhancing players' situational interest and situational self‐efficacy. However, although the intervention improved the participants' conceptual fraction knowledge, there was no significant difference between the scaffolding conditions in participants' learning outcomes.TakeawaysThe results suggest that emotional design can increase the educational impact of game‐based learning by promoting the development of interest, as well as improving self‐efficacy.

Published: August 2022

AbstractThe small cyprinid genus Prolabeops Schultz, 1941 is restricted to the Nyong and Sanaga River systems in Cameroon. In the past, the genus had been suggested to be either a member of the Labeoninae, Torinae or the Smiliogastrinae mainly on the basis of morphological similarities, and it is nowadays considered as incertae sedis within the Cypriniformes. This study provides the first attempt to reveal the phylogenetic position of Prolabeops using molecular data. For this purpose, the authors sequenced a large fraction of the mitochondrial genome (c. 13,600 bp), including all mitochondrial protein coding genes, of two Prolabeops melanhypopterus specimens and an additional four Enteromius specimens. The large‐scale phylogenetic analysis was based on an alignment including all mitochondrial protein coding genes of 902 specimens representing c. 899 cypriniform species. Prolabeops was clearly recovered within the African Smiliogastrinae, forming a weakly supported clade together with Enteromius jae, Enteromius hulstaerti and Barboides gracilis. The study data underline the urgent need of a thorough taxonomic revision of the small African barbs collectively placed in the genus Enteromius.
Aggregation bias and its drivers in large‐scale flood loss estimation: A Massachusetts case study
Authors: Pollack Adam B. , Sue Wing Ian , Nolte Christoph 
Published: August 2022

AbstractLarge‐scale estimations of flood losses are often based on spatially aggregated inputs. This makes risk assessments vulnerable to aggregation bias, a well‐studied, sometimes substantial outcome in analyses that model fine‐grained spatial phenomena at coarse spatial units. To evaluate this potential in the context of large‐scale flood risk assessments, we use data from a high‐resolution flood hazard model and structure inventory for over 1.3 million properties in Massachusetts and examine how prominent data aggregation approaches affect the magnitude and spatial distribution of flood loss estimates. All considered aggregation approaches rely on aggregate structure inventories but differ in whether flood hazard is also aggregated. We find that aggregating only structure inventories slightly underestimates overall losses (−10% bias), and when flood hazard data is spatially aggregated to even relatively small spatial units (census block), statewide aggregation bias can reach +366%. All aggregation‐based procedures fail to capture the spatial covariation of inputs distributions in the upper tails that disproportionately generate total expected losses. Our findings are robust to several key assumptions, add important context to published risk assessments and highlight opportunities to improve flood loss estimation uncertainty quantification.
Synthesising existing research on complicated grief in intellectual disability: findings from a systematic review

Published: August 2022

AbstractBackgroundComplicated grief has been identified as a phenomenon in the general population, and there is an increasing body of research investigating complicated grief in people with intellectual disability. The aim of this study is to synthesise this existing knowledge from research published between 1999 and 2022.MethodsA structured systematic review using PRISMA guidelines was conducted, which searched three commonly used databases (Medline, PsycINFO and CINAHL) for research on the topic of bereavement and intellectual disability. The articles identified in this search were screened to identify those that addressed the issue of ‘complicated grief’, with all abstracts and subsequent full texts reviewed by two researchers.ResultsIn total, 179 abstracts were initially identified, with 34 articles eligible for full text screening and 18 papers reaching criteria for inclusion. Data relating to the studies' objectives were extracted under the headings of definition, defining principles, signs and symptoms, risk factors and treatments for complicated grief in intellectual disability. Thematic analysis of the extracted data was performed to identify key themes.ConclusionsThis review highlights that people with intellectual disability are likely to experience complicated grief reactions and that complicated grief is both underestimated and a clinically significant condition for people with intellectual disability. Future research should work to clarify diagnostic criteria and identify appropriate interventions.
Out of Bounds: Do SPF Respondents Have Anchored Inflation Expectations?
Authors: BINDER CAROLA , JANSON WESLEY , VERBRUGGE RANDAL 
Published: August 2022

AbstractSince the Federal Open Market Committee announced a 2% inflation target in 2012, the median long‐run inflation forecast of professional forecasters has been near target. We show, however, that most individual forecasters' long‐run inflation expectations fluctuate substantially, with sizeable departures from target. We propose a new “bounds anchoring” indicator based on deviations of individuals' long‐run forecasts from target. This indicator sheds new light on gradual changes in expectations since the 2012 announcement. We find that bounds anchoring gradually strengthened in the years following the target announcement, but that this trend has recently started to reverse.
The Time‐Varying Response of Hours Worked to a Productivity Shock
Authors: LI HUACHEN 
Published: August 2022

AbstractThis paper revisits the dynamic response of hours worked to a total factor productivity (TFP) shock. I estimate a structural vector autoregression that includes time‐varying parameters and stochastic volatility. The estimation produces structural parameters that are consistent with the long‐run identification. The impulse response functions of hours worked to a TFP shock are negative on impact and at the business cycle horizons. This is evidence that Galí (1999) would interpret as supporting new Keynesian theory. My results also show that TFP shocks are the dominant source of variation in average labor productivity. Structural changes in the U.S. economy play an important role in the TFP–hours worked relationship.
Fostering telecompetence: A descriptive evaluation of clinical psychology predoctoral internship and postdoctoral fellowship implementation of telehealth education
Authors: Perle Jonathan G. , Perle Alexandria R. , Scarisbrick David M. , Mahoney James J. 
Published: August 2022

AbstractPurposeTelehealth education within clinical psychology predoctoral internships and postdoctoral fellowships has become a frequent recommendation designed to prepare future providers with evidence‐informed telehealth skills that can be applied to rural populations. Unfortunately, the availability of telehealth training among internships and fellowships, as well as areas for growth, remains unclear. Thus, the current study evaluated graduate clinical psychology internship and fellowship integration of telehealth training components before and after the onset of COVID‐19.MethodsIndividuals representing 74 internships and 29 fellowships completed author‐created REDCap‐hosted demographic and telehealth training surveys.FindingsBefore COVID‐19, 2 internships and 4 fellowships reported implementing telehealth education, with a majority of materials for both types of programs being optional educational targets and generally encompassing 0‐15 hours of student education. After the onset of COVID‐19, 72 internships and 27 fellowships indicated implementing telehealth education, with a majority indicating materials as mandatory and encompassing between 0 and 50+ hours. Despite increases, 73.6% of internship programs and 62.1% of fellowship programs noted a desire for their students to receive additional telehealth education in the future. Integrated educational foci are discussed.ConclusionsThe current study demonstrated positive trends in the development of telehealth education among internships and fellowships. Nevertheless, some programs can likely benefit from additional integration of telehealth components, as well as more formal programming built around field‐supported competencies and models. While work is required to further clarify field offerings, the current study provided a preliminary evaluation of internship and fellowship telehealth educational offerings.
For the future and from afar: Psychological distance and inventory decision‐making
Authors: Kirshner Samuel N. , Moritz Brent B. 
Published: August 2022

Determining inventory ahead of knowing customer demand is a crucial decision for many businesses. Although it is possible to select the ideal order quantity given the costs of over and undersupplying demand, prior research demonstrates that decision‐makers consistently make suboptimal inventory choices. Drawing on construal level theory and psychological distance, this paper explores how differences in the spatial distance (suppliers that are geographically near or far) and temporal distance (short or long lead time from order to receipt) impact newsvendor decision‐making. Across four experiments ( N = 663), we find that a far psychological distance increases order quantities, which improves performance for high‐margin products but results in added costs for low‐margin goods. Given that spatial and temporal distances occur naturally in supply chains, our research shows that psychological distance is a cognitive explanation for biased inventory ordering and can be applied to improve decision‐making.
