AbstractIn this manuscript, based on the most widespread fixed point theories in literature. The existence of solutions to the system of nonlinear fractional differential equations with Caputo Hadmard fractional operator in a bounded domain is verified by using Mönoch’s fixed point theorem, The stability of the coupled system is also investigated via Ulam-Hyer technique. Finally, an applied numerical example is presented to illustrate the theoretical results obtained.
On the analysis of fractional calculus operators with bivariate Mittag Leffler function in the kernel

Published: February 2024

AbstractBivariate Mittag-Leffler (ML) functions are a substantial generalization of the univariate ML functions, which are widely recognized for their significance in fractional calculus. In the present paper, our initial focus is to investigate the fractional calculus properties of the integral and derivative operators with kernels including the Bivariate ML functions. Further, certain fractional Cauchy-type problems including these operators are considered. Also the numerical approximations of the Caputo type derivative operator are investigated. The theoretical results are justified by applications on examples. Furthermore, the theory of applying the same operators with respect to arbitrary monotonic functions is analyzed in this research.
Controlled-environment agriculture for an urbanised world? A comparative analysis of the innovation systems in London, Nairobi and Singapore

Published: February 2024

AbstractMultiple crises and challenges in the food sector are driving a rising need for innovative food production methods that could provide a growing urban population with high-quality, sustainable and healthy food while strengthening the resilience of food systems. Controlled-environment agriculture (CEA) in urban areas has been proposed as one possible pathway to address these demands. Despite its various potential benefits, CEA is still in a conceptual or experimental stage and there has been less research that focuses on the specificities of urban areas where it could be implemented. Using the Urban Food Production Innovation System (UFoPrInS) concept, this paper analyses the urban contexts and enabling and impeding factors for implementing CEA in three contrasting locations: London, Nairobi and Singapore. Based on document analysis and semi-structured expert interviews, our findings show that Singapore is a favourable location because public policies support the implementation of CEA to reduce food import dependency and enhance the resilience of food supply. In London, high food import dependency is increasingly seen as problematic, but the implementation of CEA has been hampered by other policy priorities. In Nairobi, where over half of the population lives in informal settlements without adequate food, water and sanitation, CEA is unlikely to make an economically efficient contribution to food security. We conclude that the implementation of CEA might be suitable in locations with ample capital and knowledge, stable political, social, and infrastructure conditions, and limited space, where value can be linked to hospitality and tourism, supported by positive pricing for resource savings.

AbstractThis paper recovers implicit quiescent optical solitons for the Lakshmanan–Porsezian–Daniel equation that is studied with nonlinear chromatic dispersion and power-law of self-phase modulation. The Lie symmetry analysis has made this retrieval possible. An interesting observation has been made with the results that was not recoverable from the prequel paper.
The Incalculability of the Generated Text
Authors: Kuchtová Alžbeta 
Published: February 2024

AbstractIn this paper, I explore Derrida’s concept of exteriorization in relation to texts generated by machine learning. I first discuss Heidegger’s view of machine creation and then present Derrida’s criticism of Heidegger. I explain the concept of iterability, which is the central notion on which Derrida’s criticism is based. The thesis defended in the paper is that Derrida’s account of iterability provides a helpful framework for understanding the phenomenon of machine learning–generated literature. His account of textuality highlights the incalculability and mechanical elements characteristic of all texts, including machine-generated texts. By applying Derrida’s concept to the phenomenon of machine creation, we can deconstruct the distinction between human and non-human creation. As I propose in the conclusion to this paper, this provides a basis on which to consider potential positive uses of machine learning.
Semi-conductive carbon from industrial tea waste biomass for a p-n junction
Authors: Akgül Gökçen , Tomakin Murat , Erkaya Hasan Hüseyin 
Published: February 2024

AbstractSome semiconducting carbonaceous material was developed from industrial tea waste biomass by catalytic pyrolysis and heteroatom doping; then, a p-n junction was realized on an n-type Si substrate. I-V characteristics of the structures revealed that each structure had a different reverse saturation current, ideality factor, cut-in voltage and series resistance. The variations in the characteristics are attributed to the amorphous and non-uniform nature of the carbonaceous material. Due to the high resistivity of the carbonaceous material, a significant amount of series resistance was present in the characteristics, resulting in very small levels of current that would inhibit the practical use of the structure as a semiconductor diode in electronic circuits.
Bridging the gap: enhancing socio-ecological resilience by breaking the debt cycle among small-scale hilsa fishers in Bangladesh

Published: February 2024

AbstractThis study examines the plight of hilsa fishers in Bangladesh, grappling with challenges such as poor market access, scant capital, and shrinking fish stocks. This situation led to the seasonal dadon loan system, which provides immediate financial aid but often traps many fishers in a relentless debt cycle. We adopted a socio-ecological systems (SES) framework to examine the interconnected social and ecological dynamics of the hilsa fishery industry. Using a blend of quantitative surveys and qualitative interviews, we assessed the impact of the dadon loan system on small-scale fishers across four fishing locales in Bangladesh. The results indicate that the dadon loan system is a temporary financial prop for fishers but perpetuates debt cycles and curbs long-term financial security. Factors such as restricted access to formal credit, high fishing costs, and inadequate government support drive this system. This study identifies potential alternatives, such as government-backed loans, community finance schemes, and the promotion of alternative livelihoods, which could reduce reliance on the dadon loan system and improve fishers’ socioeconomic conditions. Implementing these strategies may dismantle the debt cycle, boost fishers’ welfare, and strengthen the socio-ecological resilience of fishing communities.

Published: February 2024

Abstract
Background
Many studies have covered the prevalence of obesity in different populations. However, studies on the prevalence and predictors of obesity among medical staff are lacking. The aim of our study is to investigate the prevalence of obesity among medical staff and to identify the related predictors.

Methods
Using a snowballing recruitment strategy in the form of an electronic questionnaire, a cross-sectional survey was conducted among 1201 medical staff from cooperative hospitals between January and March 2022. We designed a questionnaire to investigate the participants’ demographic, lifestyle, diet, physical activity, and work status.

Results
The overall prevalence of obesity was 8.5%, with males (13.7%) having a greater incidence than females (5.7%) (p < 0.001). Multiple logistic regression analyses showed that alcohol drinking (OR, 2.34; 95% CI 1.23–4.42, p = 0.01), sugar-sweetened beverages consumed > 3/week (OR, 2.50; 95% CI 1.02–6.15, p = 0.046), and working a night shift > 1/week (OR, 2.17; 95% CI 1.02–4.61, p = 0.043) were independent predictive factors for obesity in men. For women, having midnight snack having midnight snack (OR, 2.93;95% CI 1.24–6.96, p = 0.015), good sleep quality (OR, 4.47; 95% CI 1.10–21.70, p = 0.038), and working a night shift > 1/week (OR, 3.62; 95% CI 1.73–7.57, p = 0.001) were independently associated with obesity.

Conclusions
Obesity presented a low prevalence among medical staff. Alcohol drinking, drinking sugar-sweetened beverages > 3/week, and night shift > 1/week predicted a higher risk of obesity in males. In females, having midnight snack, good sleep quality, and night shift > 1/week were independently associated with obesity.

Abstract
Introduction
Central precocious puberty (CPP) is characterized by the early onset of puberty and is associated with the critical processes involved in the pubertal switch. The puberty-related gene pool in the human genome is considerably large though few have been described in CPP. Within those genes, the genomic imprinting features of the MKRN3 and DLK1 genes add additional complexity to the understanding of the pathologic pathways. This study aimed to investigate the molecular etiology in the CPP cohort.

Methods
Eighteen familial CPP cases were investigated by Sanger sequencing for five CPP-related genes; DLK1, KISS1, KISS1R, MKRN3, and PROKR2. Segregation analysis was performed in all patients with pathogenic variants. Using an ELISA test, the functional pathogenicity of novel variants was also investigated in conjunction with serum delta-like 1 homolog (DLK1) concentrations.

Results
In three probands, a known variant in the MKRN3 gene (c.982C>T/p.(Arg328Cys)) and two novel variants in the DLK1 gene (c.357C>G/p.(Tyr119Ter) and c.67+78C>T) were identified. All three were inherited from the paternal allele. The individuals carrying the DLK1 variants had low detectable DLK1 levels in their serum.

Conclusions
The frequencies were 5.5% (1/18) for MKRN3 11% (2/18) for DLK1, and none for either KISS1, KISS1R, and PROKR2. Low serum DLK1 levels in affected individuals supported the relationship between here described novel DLK1 gene variants with CPP. Nonsense nature of c.357C>G/p.(Tyr119Ter) and an alteration in the evolutionarily conserved nucleotide c.67+78C>T suggested the disruptive nature of the variant's compatibility with CPP.

Published: February 2024

AbstractCompared with traditional piezoelectric ultrasonic devices, optoacoustic devices have unique advantages such as a simple preparation process, anti-electromagnetic interference, and wireless long-distance power supply. However, current optoacoustic devices remain limited due to a low damage threshold and energy conversion efficiency, which seriously hinder their widespread applications. In this study, using a self-healing polydimethylsiloxane (PDMS, Fe-Hpdca-PDMS) and carbon nanotube composite, a flexible optoacoustic patch is developed, which possesses the self-healing capability at room temperature, and can even recover from damage induced by cutting or laser irradiation. Moreover, this patch can generate high-intensity ultrasound (> 25 MPa) without the focusing structure. The laser damage threshold is greater than 183.44 mJ cm−2, and the optoacoustic energy conversion efficiency reaches a major achievement at 10.66 × 10−3, compared with other carbon-based nanomaterials and PDMS composites. This patch is also been successfully examined in the application of acoustic flow, thrombolysis, and wireless energy harvesting. All findings in this study provides new insight into designing and fabricating of novel ultrasound devices for biomedical applications.
Enhanced High-Temperature Cycling Stability of Garnet-Based All Solid-State Lithium Battery Using a Multi-Functional Catholyte Buffer Layer

Published: February 2024

AbstractThe pursuit of safer and high-performance lithium-ion batteries (LIBs) has triggered extensive research activities on solid-state batteries, while challenges related to the unstable electrode–electrolyte interface hinder their practical implementation. Polymer has been used extensively to improve the cathode-electrolyte interface in garnet-based all-solid-state LIBs (ASSLBs), while it introduces new concerns about thermal stability. In this study, we propose the incorporation of a multi-functional flame-retardant triphenyl phosphate additive into poly(ethylene oxide), acting as a thin buffer layer between LiNi0.8Co0.1Mn0.1O2 (NCM811) cathode and garnet electrolyte. Through electrochemical stability tests, cycling performance evaluations, interfacial thermal stability analysis and flammability tests, improved thermal stability (capacity retention of 98.5% after 100 cycles at 60 °C, and 89.6% after 50 cycles at 80 °C) and safety characteristics (safe and stable cycling up to 100 °C) are demonstrated. Based on various materials characterizations, the mechanism for the improved thermal stability of the interface is proposed. The results highlight the potential of multi-functional flame-retardant additives to address the challenges associated with the electrode–electrolyte interface in ASSLBs at high temperature. Efficient thermal modification in ASSLBs operating at elevated temperatures is also essential for enabling large-scale energy storage with safety being the primary concern.
The effects of product and process innovation on employment: a meta-regression analysis
Authors: Arenas Díaz Guillermo , Guerrero Alex J. , Heijs Joost 
Published: February 2024

AbstractThe fast emergence of intensive robotization in combination with artificial intelligence implies a reappearance of the debate about the effects of innovation on the labor market. Many empirical studies have explored this phenomenon at the micro level, especially since the surge of innovation surveys, which use worldwide standardized indicators at the firm level. Most empirical studies suggest a robust, positive labor effect generated by new products, while the impact of process innovations on employment seems to be ambiguous. This paper offers a meta-regression analysis to seek some logical explanations for the results reflected in studies that apply the model proposed by Harrison et al. Our meta-regression suggests that the effect of sales growth due to new products on employment seems to be homogeneous and positive by different types of sub-samples. However, the labor effect of process innovation on employment depends on different circumstances. Its magnitude seems to be more negative for developing countries, manufacturing sectors, and periods of crisis. On the other hand, the magnitude tends to be positive for samples with the methodological approach (using instrumental variables), control variables, and high-tech sectors. The exercise is repeated, splitting the sample between developing and developed countries.
Inspiring self-regulated learning in everyday classrooms: teachers’ professional competences and promotion of self-regulated learning
Authors: Karlen Yves , Hertel Silke 
Published: February 2024

AbstractToday’s success metrics extend beyond traditional literacy and numeracy to encompass strategic learning with a growth mindset, equipping individuals with the attitude and skills to navigate and surmount new challenges. In a digital era, where information is readily available and knowledge constantly evolves, the value placed on learners is not merely based on their current knowledge but on their courage and capability to continually engage cognitive, metacognitive, motivational, social, and emotional resources for lifelong learning. In this dynamic landscape, self-regulated learning (SRL) skills are crucial, empowering students of all ages to take control of their learning journey. SRL, the goal-directed process of monitoring and regulating one’s learning activities, has been shown to significantly influence academic outcomes. Although teachers acknowledge SRL’s relevance, it remains underrepresented in everyday teaching practices, impacting not just student learning but also the training and experiences of preservice teachers in the classroom. This gap perpetuates misconceptions about SRL and hinders its integration into educational settings. Therefore, this special issue first introduces the INSPIRE model of teachers’ multiple roles as instructors, navigators, strategists, promoters, innovators, role models, and encouragers in supporting students to become self-regulated learners and describes teachers’ professional competences to fulfil these roles. Second, it dedicates four articles to exploring teachers’ professional competences in SRL and its promotion in everyday school. The articles address particular aspects of the INSPIRE model and highlight the importance of teachers equipped with the necessary training and competences to guide students in becoming self-regulated learners. Linking the research areas of teachers’ professional competences in SRL and teachers’ promotion of SRL in the classroom this special issue offers a comprehensive approach to SRL in everyday school and opens up perspectives for the transfer into practice.
Post-operative Patellar Tilt More than 10° Can Affect Certain Components of Knee Society Score After Total Knee Arthroplasty at 2-Year Follow-Up

Published: February 2024

Abstract
Introduction
The effect of post-operative patella tilt on functional outcomes after total knee arthroplasty remains unclear. Our study aimed to analyze the relationship of post-operative patellar tilt with functional outcome scores after total knee arthroplasty.

Materials and Methods
Patient data were retrieved from our institution’s prospectively maintained total knee arthroplasty. Three hundred three patients who underwent unilateral TKA from Jan 2012 to March 2017 were included in the study. After excluding patients with incomplete and lost follow-up data, 213 patients were analyzed. Radiographs of pre-operative and post-operative skyline views were used for patella tilt and patella displacement measurement at pre-op, post-op 1 year, and post-op 2 years. Three functional outcome scoring systems, SF-36, KSS, and WOMAC, were applied for function evaluation at different post-operative time points. Patients were divided into three subgroups according to the patella tilt, which includes less than 5°, 5.1–10°, and more than 10°. Statistical analysis was done to identify the relationship between patella tilt and functional outcomes.

Results
Mean post-operative patella tilt was significantly lower than the mean pre-operative patella tilt (3.35 ± 3.91 vs. 5.65 ± 4.41, p < 0.001). There was no significant difference in patella displacement among pre- and post-operative status. KSS functional score was significantly poor at post-op 1 year and KSS objective score at post-op 2 years in patients with more than 10° patella tilt. SF-36 and WOMAC were not significantly different among the groups. There was no significant difference in post-operative function between non-resurfaced and resurfaced patella patients evaluated with three scoring systems.

Conclusion
We have found significantly less post-operative patella tilt after TKA than pre-operative patella tilt with or without patella resurfacing. Increased post-operative patella tilt of more than 10° can affect specific functional outcomes. Patella resurfacing does not affect the post-operative functional outcome compared to non-resurfacing of the patella post-op 2 years.

Abstract
Introduction
HbC is a common structural hemoglobinopathy especially in West Africa. Prevalence and regional distribution of HbC in Saudi Arabia are widely undocumented. Patients with homozygous HbC disease may have mild hemolytic anemia whereas combination with hemoglobin S (HbS) leads to a clinically severe phenotype.

Aim
The current epidemiological study, considered the largest from Saudi Arabia, aimed to evaluate the regional prevalence of the HbC variant among the couples participating in the premarital screening program from 2011 to 2018.

Methods
Data from the PMSGC program were obtained for premarital screening and genetic counseling. The collected data were then entered into the SEHA platform, a centralized electronic repository for the 13 designated regions in Saudi Arabia. Hemoglobin electrophoresis samples are analyzed using either HPLC, capillary electrophoresis, or a combination of both methods to confirm the presence of abnormal hemoglobin bands.

Results
This study included 1,871,184 individuals from 2011 to 2018. Of those, 49.8% were males and 50.2% were females. 112,618 (6.0%) had an abnormal test. Total number of Hb C cases were 778 (0.04%). HbC trait (HbAC) was detected in 764 participants while homozygous HbC (HbCC) and combined heterozygous (HbSC) were found in 9 and 5 cases, respectively. The regions near the Red Sea have higher rates than the central and eastern regions.

Conclusion
HbC is a rare variant in Saudi Arabia with varying regional frequencies. HbC variant is more common in Mecca and Madina regions. The geographic area of HbC distribution differs from the areas with high prevalence of HbS, which explains why HbSC disease cases are overwhelmingly rare.
