Abstract
The rich performance characteristics of lithium-ion batteries make them extensively used for both primary and secondary applications. The Battery Management System plays a vital role in the measurement of health indicating factors such as state of health, state of power, Internal resistance, temperature, and rate of reactions. From this, it gives useful information about battery degradation. In this paper, a review is made for studying various key topics such as (i) different generations of BMS and their functions associated with monitoring, analysing, and predicting, (ii) battery electrode materials and their potential advantages and disadvantages. Various types of cathode materials such as Lithium Manganese Oxide (LMO), Lithium-Ion Phosphate (LFP). Nickel Cobalt Manganese (NCM), are discussed with respect to the features terminal voltage, safety, long life, and thermal stability. Similarly, the anode materials graphite, graphene, LTO and, silicon is also taking part in battery performance and the health indicating factors such as irreversibility, specific capacity, SEI layer, structural deformation, lithium diffusion rate, ionic conductivity are considered for the discussion. It is stated that the columbic efficiency of these materials is 95.4%. (iii) The battery degradation happens in every stage of the battery life cycle. The battery life cycle refers to the designing of battery materials, manufacturing, production state, and usage in primary and secondary applications. The various factors such as external factors and aging factors (internal side reaction and storage degradation) are studied in terms of various degradation modes are studied. The results for the cell voltage variation under various temperature is tested and dependent-characteristics are analysed using contour graphical analysis. Under high temperature the voltage drop is accelerated more and it is indicated in green region of the contour plot. In addition, it is observed that, the temperature from 32°C - 34°C, the change in cell voltage variation is minimum.

Abstract
The Floating Solar Photovoltaic (FSPV) systems are expected to perform relatively at a higher efficiency level as compared to ground mounted PV systems. The major factor affecting the operating efficiency of a solar panel is the operating temperature of the PV panel which is relatively lower as compared to ground mounted PV system. To accomplish this, an experiment setup of FSPV system has been developed which consists of solar panels operating at different heights above water surface. The findings indicate that FSPV modules can reduce the module temperature by up to 4°C – 7°C. The performance of FSPV has been analysed under diurnal conditions. The performance has been assessed in terms of power output by utilising module parameters. The results highlight the power output from solar panel under varying heights help to optimize the operating heights of the solar panels over the water bodies to achieve maximum power output. Therefore, it is also advised for FSPV to raise the PV modules to their optimal height. The FSPV systems at 500 mm height provided 1.8-3.78% higher power output than ground mounted PV systems, maximum of all the panels above water.

Published: July 2024

Abstract
This paper introduces a novel approach for harnessing Switched Reluctance Motors (SRMs) in Solar Assisted Hybrid Electric Vehicles. Given the inherent limitations of low output voltage from photovoltaic (PV) systems, an innovative solution is presented using a high gain KY converter to boost the PV output. The stability of the converter’s output is ensured through the implementation of a Proportional Integral (PI) controller, which then feeds the 8/6 SRM via a (n+1) diode (n+1) semiconductor configuration. Precise control of the SRM’s speed is achieved using a PI controller, which optimizes its operation. The excess energy generated by the PV system is intelligently diverted towards battery charging. This energy storage system is linked to the DC bus through a bidirectional battery converter. Control over the bidirectional battery converter’s operation is maintained with the aid of a PI controller, allowing surplus energy from the PV system to be stored in the battery. This stored energy can subsequently be released and supplied to the SRM drive when required. The effectiveness of this proposed methodology is rigorously evaluated through MATLAB simulations, yielding tangible results that verify its performance.

Abstract
The pursuit of sustainable energy solutions has led to increased interest in harnessing solar power through photovoltaic systems. To optimize the energy conversion and storage process, this study presents the development and performance evaluation of a low-cost N-Channel MOSFET PID Solar Charge Controller specifically designed for a Floating Solar Photovoltaic system. The controller employs a PID algorithm to regulate the PWM (Pulse Width Modulation) signal, effectively managing the charging of a lead-acid battery. In this experimental study, it was observed that the N-Channel MOSFET-based PWM Charge Controller performs comparably to its P-Channel counterpart, indicating its suitability for solar energy applications. The output current is controlled by a PID algorithm that can pin out the target current by 100%. Furthermore, the use of the N-Channel MOSFET not only maintains performance but also reduces the overall cost of constructing the PWM Charge Controller. The findings of this research carry significant implications for the field of solar energy management. The study offers a practical, cost-effective solution for solar charge regulation, particularly in Floating Solar Photovoltaic systems. By encouraging the adoption of low-cost N-Channel MOSFET controllers, this work contributes to the promotion of sustainable energy solutions and cost-effective implementations in the renewable energy sector.

Published: July 2024

Abstract
The Matrix Converter (MC), also acknowledged as an AC/AC converter, represents a singular one-stage converter that consolidates the multiple conversion stages and intermediary energy storage components inherent in direct converters into a unified power conversion process. This novel design enables the establishment of a variable output voltage system characterized by unrestricted frequency adaptability. MC employs a set of controlled bidirectional switches as their primary power components. The current investigation focuses on the modelling and simulation of MCs, specifically addressing 1-Φ to 1-Φ, 2-Φ to 1-Φ, 3-Φ to 1-Φ, and 3-Φ to 3-Φ configurations. The simulation is executed using MATLAB/Simulink, yielding comprehensive outcomes for diverse MC setups.
Authoring Asceticism in Late Roman Gaul, ca. 400–430
Authors: Ungvary David 
Published: July 2024

Abstract
This chapter pivots from analysis of poetry specifically to outline an emergent conversation over best Christian literary practices among participants in the monastic movement of southern Gaul, and to examine the ascetic textual communities that formed around competing literary programs and procedures. Investigation focuses on innovations in ascetic reading, writing, and education developed by regional monastic experts and impresarios—Sulpicius Severus, John Cassian, and Eucherius of Lyon—whose theories and practices of literature stood in various degrees of tense relation with traditional aristocratic versions. Interpretations of their experiments in monastic literacy illuminate important facets of Gaul’s nascent ascetic culture. As ascetic leaders strived to define their own religious authority, they were particularly anxious to determine the nature of ascetic intellectualism and fix their communities’ distance from literary “worldliness.” Driven by these concerns, authorities from these groups produced competing diagnoses of, and remedies for, Christian society’s concerning relation to classicizing composition and the reading of secular texts.
Announcing Renunciation
Authors: Ungvary David 
Published: July 2024

Abstract
This chapter offers an account of Sidonius Apollinaris’s renunciation of verse composition upon his entry into the episcopacy in ca. 470. It explores why he continued to write verse during his episcopal tenure and what his late poetic exercises might have signified to his Gallo-Roman audience. To help explain Sidonius’s fraught relationship to poetry, readings probe his connections to the monks of Lérins and their ascetic literary program, developed through correspondence within the Gallic episcopacy. The chapter concludes with treatment of the last texts in Sidonius’s corpus, a series of prosimetric letters from the late 470s that seem to contravene the bishop’s disavowal of verse writing. By virtue of these final poems, the chapter suggests, Sidonius raised anew the question of whether a classical lyrical mode of self-presentation could be converted to a pious practice of ascetic self-reflection.

Published: July 2024

Abstract

Background
Epigenetic ageing is among the most promising ageing biomarkers and may be a useful marker of physical function decline, beyond chronological age. This study investigated whether epigenetic age acceleration (AA) is associated with the change in frailty scores over 7 years and the 7-year risk of incident frailty and persistent Activities of Daily Living (ADL) disability among 560 Australians (50.7% females) aged ≥70 years.

Methods
Seven AA indices, including GrimAge, GrimAge2, FitAge and DunedinPACE, were estimated from baseline peripheral-blood DNA-methylation. Frailty was assessed using both the 67-item deficit-accumulation frailty index (FI) and Fried phenotype (Fried). Persistent ADL disability was defined as loss of ability to perform one or more basic ADLs for at least 6 months. Linear mixed models and Cox proportional-hazard regression models were used as appropriate.

Results
Accelerated GrimAge, GrimAge2, FitAge and DunedinPACE at baseline were associated with increasing FI scores per year (adjusted-Beta ranged from 0.0015 to 0.0021, P &lt; 0.05), and accelerated GrimAge and GrimAge2 were associated with an increased risk of incident FI-defined frailty (adjusted-HRs 1.43 and 1.39, respectively, P &lt; 0.05). The association between DunedinPACE and the change in FI scores was stronger in females (adjusted-Beta 0.0029, P 0.001 than in males (adjusted-Beta 0.0002, P 0.81). DunedinPACE, but not the other AA measures, was also associated with worsening Fried scores (adjusted-Beta 0.0175, P 0.04). No associations were observed with persistent ADL disability.

Conclusion
Epigenetic AA in later life is associated with increasing frailty scores per year and the risk of incident FI-defined frailty.
Cocoa extract induces browning of white adipocytes and improves glucose intolerance in mice fed a high-fat diet
Authors: Yonemoto Eito , Ihara Risa , Tanaka Emi , Mitani Takakazu 
Published: July 2024

ABSTRACT
Cocoa extract (CE) offers several health benefits, such as antiobesity and improved glucose intolerance. However, the mechanisms remain unclear. Adipose tissue includes white adipose tissue (WAT) and brown adipose tissue. Brown adipose tissue leads to body fat reduction by metabolizing lipids to heat via uncoupling protein 1 (UCP1). The conversion of white adipocytes into brown-like adipocytes (beige adipocytes) is called browning, and it contributes to the anti-obesity effect and improved glucose tolerance. This study aimed to evaluate the effect of CE on glucose tolerance in terms of browning. We found that dietary supplementation with CE improved glucose intolerance in mice fed a high-fat diet, and it increased the expression levels of Ucp1 and browning-associated gene in inguinal WAT. Furthermore, in primary adipocytes of mice, CE induced Ucp1 expression through β3-adrenergic receptor stimulation. These results suggest that dietary CE improves glucose intolerance by inducing browning in WAT.

Abstract

Background
Monilethrix is a rare hereditary hair disorder that is characterized by a beaded hair shaft structure and increased hair fragility. Patients may also present with keratosis pilaris and nail changes. Research has identified three genes responsible for autosomal dominant monilethrix (KRT81, KRT83, KRT86) and one responsible for the autosomal recessive form (DSG4).

Objectives
To investigate the genetic basis of autosomal dominant monilethrix in families with no pathogenic variants in any of the known monilethrix genes, and to understand the mechanistic basis of variant pathogenicity using a cellular model.

Methods
Nine affected individuals from four unrelated families were included. A clinical diagnosis of monilethrix was assigned based on clinical examination and/or trichoscopy. Exome sequencing was performed in six individuals to identify pathogenic variants; Sanger sequencing was used for co-segregation and haplotype analyses. Cell culture experiments [immunoblotting, immunofluorescence and reverse transcription quantitative real-time polymerase chain reaction (RT-qPCR) analyses] were used to confirm variant pathogenicity, to determine the expression and subcellular localization of proteins, and to identify possible nonsense-mediated mRNA decay.

Results
In six affected individuals with clinically suggested monilethrix, exome sequencing led to the identification of the nonsense variant c.1081G&gt;T; p.(Glu361*) in KRT31, which was subsequently identified in other affected members of these families by Sanger sequencing. This variant led to the abolition of both the last three amino acids of the 2B subdomain and the complete C-terminal tail domain of keratin 31. Immunoblotting demonstrated that when co-expressed with its binding partner keratin 85, the truncated keratin 31 was still expressed, albeit less abundantly than the wildtype protein. Immunofluorescence revealed that p.(Glu361*) keratin 31 had an altered cytoskeletal localization and formed vesicular-like structures in the cell cytoplasm near the cell membrane. RT-qPCR analysis did not generate evidence for nonsense-mediated decay of the mutant transcript.

Conclusions
This study is the first to identify pathogenic variants in KRT31 as a cause of autosomal dominant monilethrix. This highlights the importance of hair keratin proteins in hair biology, and will increase the molecular diagnostic yield for rare ectodermal phenotypes of hair and nail tissues.

Authors: Luebke Marie C , Neuner Joan M , Balza Joanna , Davidson Emily R W , Hokanson James A , Marowski Sarah , Corey O’Connor Robert , Schmitt Emily , Winn Aaron N , Flynn Kathryn E 
Published: July 2024

Abstract

Background
While nearly 50% of adult women report at least one episode of urinary incontinence (UI), most never receive treatment.

Objective
To better integrate primary and specialty UI care, we conducted (i) an environmental scan to assess the availability of key pathway resources in primary care, (ii) interviews with primary care providers to understand barriers to care, and (iii) a pilot UI care pathway intervention.

Methods
Environmental scan: Clinic managers from all primary care clinics within a Midwestern healthcare system were invited to participate in an interview covering the availability of clinic resources. Provider interviews: Primary care providers were invited to participate in an interview covering current practices and perceived barriers to UI care. Pilot UI care pathway: Patients who screened positive for UI were provided resources for first-line behavioral management. Pilot patients completed questionnaires at baseline, 8 weeks, and 6 months.

Results
While many clinics had point-of-care urinalysis (17/21, 81%), most did not have a working bladder ultrasound (14/21, 67%) or on-site pelvic floor physical therapy (18/21, 86%). Providers (n = 5) described barriers to completing almost every step of diagnosis and treatment for UI. The most persistent barrier was lack of time. Patients (n = 15) reported several self-treatment strategies including avoiding bladder irritants (7/15, 47%) and performing Kegel exercises (4/15, 27%). Five patients (33%) requested follow-up care. At 6 months, patients reported small improvements in UI symptoms.

Conclusion
Promising results from a novel UI care pathway pilot indicate that streamlining UI care may assist primary care providers in the first-line treatment of UI.

Abstract
Switchgrass is a potential crop for bioenergy or carbon capture schemes, but further yield improvements through selective breeding are needed to encourage commercialization. To identify promising switchgrass germplasm for future breeding efforts, we conducted multisite and multitrait genomic prediction with a diversity panel of 630 genotypes from 4 switchgrass subpopulations (Gulf, Midwest, Coastal, and Texas), which were measured for spaced plant biomass yield across 10 sites. Our study focused on the use of genomic prediction to share information among traits and environments. Specifically, we evaluated the predictive ability of cross-validation (CV) schemes using only genetic data and the training set (cross-validation 1: CV1), a subset of the sites (cross-validation 2: CV2), and/or with 2 yield surrogates (flowering time and fall plant height). We found that genotype-by-environment interactions were largely due to the north–south distribution of sites. The genetic correlations between the yield surrogates and the biomass yield were generally positive (mean height r = 0.85; mean flowering time r = 0.45) and did not vary due to subpopulation or growing region (North, Middle, or South). Genomic prediction models had CV predictive abilities of −0.02 for individuals using only genetic data (CV1), but 0.55, 0.69, 0.76, 0.81, and 0.84 for individuals with biomass performance data from 1, 2, 3, 4, and 5 sites included in the training data (CV2), respectively. To simulate a resource-limited breeding program, we determined the predictive ability of models provided with the following: 1 site observation of flowering time (0.39); 1 site observation of flowering time and fall height (0.51); 1 site observation of fall height (0.52); 1 site observation of biomass (0.55); and 5 site observations of biomass yield (0.84). The ability to share information at a regional scale is very encouraging, but further research is required to accurately translate spaced plant biomass to commercial-scale sward biomass performance.

Abstract
The Period genes (Per) play essential roles in modulating the molecular circadian clock timing in a broad range of species, which regulates the physiological and cellular rhythms through the transcription-translation feedback loop. While the Period gene paralogs are widely observed among vertebrates, the evolutionary history and the functional diversification of Per genes across vertebrates are not well known. In this study, we comprehensively investigated the evolution of Per genes at the copy number and sequence levels, including de novo binding motif discovery by comparative genomics. We also determined the lineage-specific transcriptome landscape across tissues and developmental stages and phenotypic effects in public RNA-seq data sets of model species. We observed multiple lineage-specific gain and loss events Per genes, though no simple association was observed between ecological factors and Per gene numbers in each species. Among salmonid fish species, the per3 gene has been lost in the majority, whereas those retaining the per3 gene exhibit not a signature of relaxed selective constraint but rather a signature of intensified selection. We also determined the signature of adaptive diversification of the CRY-binding region in Per1 and Per3, which modulates the circadian rhythm. We also discovered putative regulatory sequences, which are lineage-specific, suggesting that these cis-regulatory elements may have evolved rapidly and divergently across different lineages. Collectively, our findings revealed the evolution of Per genes and their fine-tuned contribution to the plastic and precise regulation of circadian rhythms in various vertebrate taxa.
