Bidirectional wide range and high voltage gain buck‐boost DC‐DC converter for EV chargers empowering V2G‐G2V applications
Authors: Gholami Zahra , Ildarabadi Rahim , Heydari‐Doostabad Hamed , Monfared Mohammad , O'Donnell Terence 
Published: December 2023

AbstractThis paper proposes a new wide range bidirectional buck‐boost dc‐dc converter with improved voltage gain in either forward (discharging) or backward (charging) direction for electric vehicle (EV) applications. The converter has high‐voltage gain ratio with no theoretical limits in the output voltage in both directions, and presents a good balance between the component count, number of conducting components, semiconductor device ratings, having direct connection between input and output terminals, and efficiency which makes it a practical solution for the EV charger levels 1, 2, and 3 power converter unit. The operating principle, steady‐state characteristics including the current and voltage stress of the switches, and comparison with other state of the art dc‐dc bidirectional converters are explained in detail. In order to validate the theoretical analysis, a 500 W, 200 V or 40 V to 180 V laboratory prototype is implemented. The obtained results confirm the applicability of this structure and demonstrate a peak efficiency of 97.2% in the forward and 97.6% in the backward direction modes of operation.

Published: December 2023

AbstractFor a sustainable system to be designed with the lowest possible cost, photovoltaic thermal (PV/T) system efficiency and heat transmission must be increased. The performance of each hybrid PV/T air system was examined using four air PV/T models with various geometric configurations. The examination of the various mathematical models revealed how each geometry configuration affected each system's performance. Air PV/T arrangements with expanded surfaces, like fins, enhance thermoelectric performance. According to the findings, the thermal efficiencies of finned absorber PV/T and finned Tedlar PV/T are, respectively, 80.3 and 77.54%. Additionally, the figures for electrical efficiencies are 11.88 and 11.93%, respectively. For these two types of PV/T systems, the annual energy output has increased and now stands at roughly 3242 and 3316 kWh/m2, respectively. Additionally, compared to other PV/T systems, the finned Tedlar PV/T system offers higher profitability in terms of cost and revenue according to an economic research.

Published: December 2023

Background The timely provision of test results to facilitate early access to treatment is an essential component of sexually transmissible infection (STI) control and contributes to a significant proportion of the workload at sexual health services. We aimed to estimate the time to deliver client results and treatment as well as the health system costs of the nurse-led urgent results management model at the Sydney Sexual Health Centre (SSHC) compared to an alternative ‘ordering clinician’ model. Methods We conducted a retrospective analysis of urgent results managed by the results nurse over 2 weeks in 2019 and an observational study over 2 weeks in 2021, where 10 clinicians managed five of their own urgent results. Additional activity data were gathered to determine the annual health system costs for both models. Results In the nurse-led model 211 of 280 clients required notification; 156 (73.9%) were notified on the day their results became available, and the median time to treatment (n = 137) was 1 day. The annual health system cost for the nurse-led model was A$3 922 143. In the ordering clinician model, 17 (42.5%) clients were notified on the same day, and of the 27 clients treated at SSHC, the median time to treatment increased to 4 days. The annual health system cost for the ordering clinician model was A$4 043 667.28 compared with the nurse-led model, and an additional 33.3 h per week of clinician time was required for the same level of service provision. Conclusions This study highlights the strengths of the nurse-led results model at SSHC, demonstrating improved client outcomes for STI notification and treatment times and health systems savings.
Harvesting pollen with vibrations: towards an integrative understanding of the proximate and ultimate reasons for buzz pollination
Authors: Vallejo-Marin Mario , Russell Avery L 
Published: December 2023

Abstract
Buzz pollination, a type of interaction in which bees use vibrations to extract pollen from certain kinds of flowers, captures a close relationship between thousands of bee and plant species. In the last 120 years, studies of buzz pollination have contributed to our understanding of the natural history of buzz pollination, and basic properties of the vibrations produced by bees and applied to flowers in model systems. Yet, much remains to be done to establish its adaptive significance and the ecological and evolutionary dynamics of buzz pollination across diverse plant and bee systems. Here, we review for bees and plants the proximate (mechanism and ontogeny) and ultimate (adaptive significance and evolution) explanations for buzz pollination, focusing especially on integrating across these levels to synthesize and identify prominent gaps in our knowledge. Throughout, we highlight new technical and modelling approaches and the importance of considering morphology, biomechanics and behaviour in shaping our understanding of the adaptive significance of buzz pollination. We end by discussing the ecological context of buzz pollination and how a multilevel perspective can contribute to explain the proximate and evolutionary reasons for this ancient bee–plant interaction.
Security, Emotions and Radical Right Populism: Beyond a ‘Flaunting of the Low’?
Authors: Hamilton Claire 
Published: December 2023

AbstractThe rise of exclusionary populism is widely regarded as one of the most significant phenomena in today’s political world. Despite this, the relationship between populism and security remains under-explored in the literature, including the affective power of populist security narratives. Against this background, this paper conducts a comparative analysis of radical right populist discourse in response to two recent shocking crimes in France and Ireland. The different expression given to security concerns in the two countries, such as a much less antagonistic ‘flaunting of the low’ in France, is suggestive of a more contingent and institutionally mediated relationship between security and populism than the existing literature would suggest.
Extracellular vesicle proteome unveils cathepsin B connection to Alzheimer’s disease pathogenesis
Authors: Yuyama Kohei , Sun Hui , Fujii Risa , Hemmi Isao , Ueda Koji , Igeta Yukifusa 
Published: December 2023

Abstract
Extracellular vesicles (EVs) are membrane vesicles that are released extracellularly and considered to be implicated in the pathogenesis of neurodegenerative diseases including Alzheimer’s disease. Here, CSF EVs of 16 ATN-classified cases were subjected to quantitative proteome analysis. In these CSF EVs, levels of 11 proteins were significantly altered during the ATN stage transitions (P &lt; 0.05 and fold-change &gt; 2.0). These proteins were thought to be associated with Alzheimer’s disease pathogenesis and represent candidate biomarkers for pathogenic stage classification. Enzyme-linked immunosorbent assay analysis of CSF and plasma EVs revealed altered levels of cathepsin B (CatB) during the ATN transition (seven ATN groups in validation set, n = 136). The CSF and plasma EV CatB levels showed a negative correlation with CSF amyloid-β42 concentrations. This proteomic landscape of CSF EVs in ATN classifications can depict the molecular framework of Alzheimer’s disease progression, and CatB may be considered a promising candidate biomarker and therapeutic target in Alzheimer’s disease amyloid pathology.
Cost-effectiveness of screening for chronic kidney disease: existing evidence and knowledge gaps
Authors: van Mil Dominique , Pouwels Xavier G L V , Heerspink Hiddo J L , Gansevoort Ron T 
Published: December 2023

ABSTRACT
It is well known that the worldwide prevalence of chronic kidney disease (CKD) has risen to over 10% of the general population during the past decades. Patients with CKD are at increased risk of both kidney failure and cardiovascular disease (CVD), posing a substantial health challenge. Therefore, screening for CKD is warranted to identify and treat patients early to prevent progression and complications. In this issue of the Journal, Yeo and colleagues provide an updated systematic review of the cost-effectiveness of screening for CKD in the general adult population. They show that screening for CKD in high-risk populations is cost-effective and that there is limited evidence for screening the general population. It should be noted that most studies they discuss do not consider the benefit of screening to prevent CVD in addition to preventing kidney failure, the treatment effect of novel therapeutic agents such as SGLT2 inhibitors, and the possibility of screening in a home-based setting. These three aspects will likely improve the cost-effectiveness of CKD screening, making it feasible to move towards general population screening for CKD.
The Mayflower and Historical Culture in Britain, 1620–2020
Authors: Downey Edmund , Hulme Tom , Vandrei Martha 
Published: December 2023

Abstract
In 2020 the Anglo-American world marked the 400th anniversary of the trans-Atlantic Mayflower voyage with a programme of activities. Intensive and focused interest in the story of the Mayflower is not a new phenomenon—especially in the United States, where it is the bedrock of the nation’s ‘origin story’. But the tale of the Pilgrims has historically also captured the British imagination. This article outlines a chronology for understanding the cultural importance in Britain of this voyage, from the New England chroniclers to the postcolonial critiques of historians today. In between, it offers a thematic analysis of the different groups which could use the story in their construction of morality and identity, from Romanticists and abolitionists to Anglo-American diplomats and civic boosters. Understanding the afterlife of the voyage in this long perspective, we argue, provides us with a more nuanced understanding of how ideas of history develop and evolve within broader arenas of politics and civil society. We use the concept of historical culture: an approach that is attuned to the interplay between memory, public history, heritage and popular history, and across forms of media (novels, plays, film) and spaces of interaction (cities, politics, movements). As the vogue for commemoration continues to exert power in Britain and beyond, and so does an increasing demand for more critical approaches to historical redress, we thus develop a critical framework that understands the powerful draw of ‘history’—both past and present.
Patients’ perception of orthodontic retainers: a systematic review
Authors: Moda Larissa Barbosa , Bastos Renata Travassos da Rosa Moreira , Flores-Mir Carlos , Normando David 
Published: December 2023

Abstract

Background
Orthodontic retainers are widely used to prevent relapses after orthodontic treatment; however, evidence about patients' perceptions of retainers is lacking.

Objective
To assess patients’ perception of orthodontic retainers.

Search Methods
PubMed, Web of Science, Scopus, LILACS, LIVIVO, Cochrane Library, and gray literature (Google Scholar) were searched without date or language restrictions. A manual search of the reference lists of the included articles was also performed.

Selection criteria
Studies comparing patients’ perceptions of wearing orthodontic retainers were included.

Data collection and analysis
According to the study design, the risk of bias (RoB) assessment was performed using RoB 2.0 or ROBINS-I. The level of evidence was assessed through the GRADE (Grading of Recommendations, Assessment, Development and Evaluation) tool.

Results
Seventeen studies met the eligibility criteria. After the RoB assessment, 12 randomized controlled trials presented a high RoB, and 4 non-randomized controlled trials presented a moderate RoB. The certainty of evidence was classified as very low for the four assessed outcomes. The studies generally reported an initial temporary negative impact of orthodontic retainers. Different esthetic, functional, and ease-of-use advantages are reported using removable and fixed retainers. A quantitative analysis was not performed due to the considerable clinical and methodological heterogeneity among the studies.

Conclusion
The current evidence, although very limited, suggests that orthodontic retainers have an initial negative impact related to discomfort and functional limitations, but they seem to regress over time. There is a preference for thermoplastic over Hawley-type retainers. However, thermoplastic retainers cause different functional difficulties, and bonded retainers present the advantage of affecting speech function less than orthodontic removable retainers, although they can facilitate oral hygiene problems.

Gender-specific treatment effects and outcomes reported in orthodontic research. A cross-sectional empirical study
Authors: Kummer Géraldine , Eliades Theodore , Koletsi Despina 
Published: December 2023

Abstract

Aim
To identify practices of assessment of gender effects in research articles in orthodontics and detect whether there were significant differences in the treatment effects on outcomes according to gender.

Materials and Methods
Four major orthodontic journals were sought over a 3-year period to identify publications which included assessment of gender effects on outcomes in their reporting. Data were extracted on the following characteristics: journal, year of publication, region of authorship, and study design. For the studies including reporting of gender effects, whether a significant effect existed was further documented. Additionally, for these studies, data were extracted on population, sample size per gender, treatment, comparison, outcome type, and nature and whether gender analysis was based on subgroup testing or included as a main effect. Descriptive statistics, cross-tabulations, univariable, and multivariable regression models were utilized as appropriate.

Results
A total of 718 research articles were eligible for inclusion out of a pool of 1,132 screened articles. Of those, 95 reported on any type of analysis on gender effects (95/718; 13.2%). In the 95 studies that reported assessment of gender effects, it was clear that the majority did not detect significant gender-related differences across the documented outcomes (range of frequency distribution for significant gender differences across all outcomes: 0–50%). Twenty-two articles overall (22/95; 23.2%) described a significant gender effect classified by outcome, 12 favoring female and 10 favoring male participants. Patterns of efficacy and adverse outcomes were schemed either favoring female (root resorption: 4/10; 40.0%, periodontal outcomes: 3/11; 27.3%) or male (cephalometric/growth changes following orthodontic treatment: 4/17; 23.5%) patients across the 22 studies with significant effects. Appropriately designed and adequately powered statistical analyses, with gender effect assessment as a main effect in a multivariable regression model was associated with 6.53 times higher odds for identifying significant gender effects (OR = 6.53; 95% CI: 2.15, 19.8; P = .001).

Conclusions
A very small proportion of research studies included gender effect assessment in their analyses. Of those, a quarter described significant effects. Nevertheless, careful analysis planning and strategies should be prioritized to allow for any meaningful interpretation.
Sounding passions and therapeutic performance in Thomas Weelkes’s songs
Authors: Butler Katherine 
Published: December 2023

Abstract
This article explores a group of Thomas Weelkes’s songs where the usually light-hearted, playful and often suggestive fa-la refrain is juxtaposed with melancholic lyrics. The contrasting passions in these texts provide inspiration for typically madrigalian musical expression, often involving chromatic writing for melancholic passages; however, the nonsense syllables in the fa-la refrains function differently. With no semantic text, the expression of these passages depends on the musical setting and the decisions taken by the performers, which might align or jar with prior expectations of fa-la refrains. Such passages are ambiguous and malleable, and the signification of the fa-las might change from stanza to stanza.
Weelkes’s experimentation with how fa-la refrains might communicate a range of passions engages with contemporary debates about the extent to which music’s affective powers were reliant on, amplified by, or independent of text. Moreover, several of Weelkes’s songs enact a therapeutic purging of melancholy attributed to non-verbal or instrumental music. Given Weelkes’s interest in exploring sonic effects which are both onomatopoeic and utilize conventions of musical expression, these songs can be interpreted as not merely representations of the passions but as potential acts of musical therapy.
The interaction mechanism between zein and folic acid in alkaline aqueous solutions: an experimental and molecular simulation study

Published: December 2023

Abstract

Objectives
Folic acid is a vitamin that is not highly soluble in water and is sensitive to the environment. Therefore, it is important to find suitable carriers. This study aimed to exemplify the interaction of folic acid with zein in alkaline aqueous solutions and shed light on how zein can be used as a carrier for folic acid.

Materials and Methods
Zein and folic acid were separately dissolved in NaOH solutions with a PH of 11.5. Zein solution and folic acid solution were combined in specific ratios. Various methods including multi-spectroscopy, dynamic light scattering, and electron microscopy combining with molecular dynamics simulations were used to study the interaction mechanism between zein and folic acid in alkaline aqueous solutions.

Results
Fluorescence spectroscopy showed that the quenching of zein by folic acid was mainly static, and the main driving force behind this interaction was van der Waals forces and hydrogen bonds. The formation of zein–folic acid complexes was confirmed by ultraviolet–visible spectroscopy, Fourier transform infrared spectroscopy, and circular dichroism spectroscopy. The results also showed that the structure of zein changed when it interacted with folic acid. Dynamic light scattering analysis revealed that the addition of folic acid caused proteins to aggregate. The aggregates of the complexes had an irregular shape and were large, as observed by scanning electron microscopy and transmission electron microscopy. Molecular simulation was used to further investigate the interaction mechanisms. According to these findings, the folic acid molecule interacted with zein in a shallow recess near the protein surface. The dominant forces at play in the zein–folic acid interaction were van der Waals forces and electrostatic forces, including hydrogen bonding.

Conclusion
The zein alkali-soluble system is very suitable for folic acid delivery.
Variation in Home Healthcare Use by Dementia Status Among a National Cohort of Older Adults
Authors: Burgdorf Julia G , Ornstein Katherine A , Liu Bian , Leff Bruce , Brody Abraham A , McDonough Catherine , Ritchie Christine S 
Published: December 2023

Abstract

Background
Medicare-funded home healthcare (HHC) delivers skilled nursing, therapy, and related services through visits to the patient’s home. Nearly one-third (31%) of HHC patients have diagnosed dementia, but little is currently known regarding how HHC utilization and care delivery differ for persons living with dementia (PLwD).

Methods
We drew on linked 2012–2018 Health and Retirement Study and Medicare claims for a national cohort of 1 940 community-living older adults. We described differences in HHC admission, length of stay, and referral source by patient dementia status and used weighted, multivariable logistic and negative binomial models to estimate the relationship between dementia and HHC visit type and intensity while adjusting for sociodemographic characteristics, health and functional status, and geographic/community factors.

Results
PLwD had twice the odds of using HHC during a 2-year observation period, compared to those without dementia (odds ratio [OR]: 2.03; p &lt; .001). They were more likely to be referred to HHC without a preceding hospitalization (49.4% vs 32.1%; p &lt; .001) and incurred a greater number of HHC episodes (1.4 vs 1.0; p &lt; .001) and a longer median HHC length of stay (55.8 days vs 40.0 days; p &lt; .001). Among post-acute HHC patients, PLwD had twice the odds of receiving social work services (unadjusted odds ratio [aOR]: 2.15; p = .008) and 3 times the odds of receiving speech-language pathology services (aOR: 2.92; p = .002).

Conclusions
Findings highlight HHC’s importance as a care setting for community-living PLwD and indicate the need to identify care delivery patterns associated with positive outcomes for PLwD and design tailored HHC clinical pathways for this patient subpopulation.

Authors: Desai Pankaja , Halloway Shannon , Krueger Kristin R , Rajan Kumar B , Evans Denis A 
Published: December 2023

Abstract

Background
This study examined the relation between declines in physical and cognitive performance in older people.

Methods
A population-based cohort of 7 483 adults (average age 72 years) were interviewed. Physical performance was assessed with 3 standardized tests and a combination of 4 cognitive tests was used to assess cognitive function. Rate of change in physical and cognitive performance was determined for each interval between interviews. In mixed effects linear regression models adjusted for age, sex, race, and study time, and change in each factor was used to predict change in the other factor. We examined time associations by using changes in the predictor measured at 1, 2, or 3 intervals before the outcome change.

Results
Decline in cognitive function was most strongly predicted by physical decline in the same 3-year interval. The decline in cognitive function was weaker in the 1-time interval after the decline in physical function and was not significant in later intervals. When a decline in cognitive function was used to predict a decline in physical function, the results were similar. The strongest association occurred in the same time interval so that declines in cognitive and physical performance tend to occur together.

Conclusions
Decline in cognition and physical function seem to occur together in a short timeframe. It is important to investigate the reasons for these changes that are short-term to guide the development of interventions.
