Published: January 2024

AbstractNowadays, human biometrics are widely used in authentication systems. In reaction to violent attacks, cancelable biometric patterns are developed from the original templates to increase the security level of biometric characteristics. This study proposes a solution for a cancelable biometrical recognition system (CBRS) based on the created Hénon chaotic-map idea, which increases key space and hence privacy. The suggested CBRS system ensures that the original biometric traits are updated and encrypted before they are saved in the database, protecting them from unwanted cyber-attacks. It makes efficient encryption of face biometric templates possible. The extraction of biometric characteristics is the first step in this design. Following that, the obtained biometric characteristics are encrypted using the suggested model, which causes pixel confusion and diffusion by developing a Henon chaotic map with variable block sizes at different modes of operation. Various face biometrics datasets were used to test the proposed approach. Various metrics, including security and statistical analyses, demonstrate the effectiveness of the approach, including histogram analysis, correlation coefficient analysis, maximum deviation factor analysis, irregular deviation factor analysis, number of pixels change rate analysis, unified average changing intensity analysis, time analysis, and key space analysis. Furthermore, the performance of the proposed approach was assessed using the receiver operating characteristic curve, which was constructed to assess the system's performance. Results of the analysis show that the suggested technique is very effective, resilient, and dependable, as evidenced by its great performance across diverse recognition databases when compared to traditional and modern algorithms, hence improving the security and reliability of biometric-based access management. The proposed method yields an average AROC of around 1, a correlation coefficient of about 0.00013, and an entropy close to one.

AbstractMicrobial fuel cells (MFCs), hailed as a promising technology, hold the potential to combat various wastewater pollutants while simultaneously converting their chemical energy into electricity through biocatalysts. This study explores the applicability of a dual compartment MFC (DC-MFC) under varying conditions, targeting the removal of chemical oxygen demand (COD) from landfill leachate and electricity generation. In this setup, anaerobic sludge from a wastewater treatment plant serves as the inoculum in the anode compartment of the MFC, with a Nafion117 membrane acting as the separator between MFC units. The cathode compartments are filled with distilled water and continually aerated for 24 h to enhance air supply. The study assesses the MFC’s performance across different COD concentrations, focusing on COD removal, power generation, and Coulombic efficiency. The findings reveal that COD removal efficiency is notably enhanced at higher concentrations of organic matter. Specifically, at a COD concentration of 3325.0 mg L−1, the MFC exhibited the highest COD removal efficiency (89%) and maximum power density (339.41 mWm−2), accompanied by a Coulombic efficiency of 25.5%. However, as the initial substrate concentration increased to 3825 mg L−1, the efficiency decreased to 72%, with a Coulombic efficiency of 13.56% and a power density of 262.34 mWm−2. Optical density levels increased due to bacterial growth at ambient temperature and neutral pH, reflecting the dynamic microbial response within the system.

AbstractThe paper describes a theoretical framework for the study of teachers’ promotion of self-regulated learning in the classroom. The Self-Regulated Learning Teacher Promotion Framework (SRL-TPF) utilizes the ICAP theory to assess the affordances of the learning environment for the indirect promotion of SRL, proposes new variables in the investigation of the direct promotion of SRL, and examines how these two ways to promote SRL are related. The SRL-TPF was used to examine the direct and indirect promotion of SRL in filmed observations of 23 Australian classrooms. The results revealed a paucity in the design of Constructive and Interactive lesson tasks that support the indirect promotion of SRL and a preference for the direct support of SRL through implicit strategy instruction and the provision of metacognitive reflection and support. There were important teacher differences in both the direct and indirect promotion of SRL, but the teachers who were more likely to design Constructive and Interactive lesson tasks did not necessarily promote SRL directly and vice versa. The research contributes to a better understanding of the relationship between teaching what to learn (subject content) and how to learn (SRL knowledge and strategies).
Assessment of functional diversity of heterotrophic microbial communities in polluted environments through community level physiological profiles
Authors: Lukhele Thabile , Msagati Titus A. M. 
Published: January 2024

AbstractThe community level physiological profiles (CLPP) of bacterial communities inhabiting polluted environments (acid mine drainage water and sediments, soils contaminated with tannery waste and oil refinery effluents) were assessed using the Biolog Ecoplates™ in comparison to non-contaminated sites (water and sediments from a recreational lake and soil from anopen space). Although the polluted sites were characterized by typically high metal concentrations, CLPP fingerprints of the different bacterial communities from these sites were indicative of versatile metabolic potentials. These microbial communities could differentially utilize all the different groups of carbon substrates. However, the rates of utilization were significantly lower, and the number of utilized substrates were fewer than those of microbial communities from non-contaminated sites. This was confirmed by cluster analysis in which the dendrogram showed two clusters of microbial communities from contaminated environments and another for those from non-contaminated sites. Nonetheless, the indices of diversity calculated did not show a reduction of diversity or evenness in the microbial communities from contaminated sites. This study confirms the usefulness of the CCLP method in untangling the functional diversity of microbial diversity in contaminated environments.
Quantifying the effects of sensory stress on trophic cascades
Authors: Ng Gabriel , Baskett Marissa L. , Gaylord Brian 
Published: January 2024

AbstractPredators mediate the strength of trophic cascades indirectly by decreasing the number of prey consuming a basal resource and by altering prey responses that dictate prey foraging. The strength of these indirect effects further depends on abiotic factors. For example, attributes of the environment, such as turbulent flows in aquatic habitats that disrupt spatial information available from chemical cues, can impose “sensory stresses” that impair the ability of predators or prey to detect each other. The multi-faceted impacts of sensory stress on both the predators and prey create challenges in predicting the overall effect on the trophic cascade. Here, we explore how sensory stress affects the strength of trophic cascades using a tri-trophic dynamical model that incorporates the sensory environment and anti-predatory responses. We explore two crucial parameters that govern outcomes of the model. First, we allow predation rates to either strengthen or weaken depending on whether prey or predators are more sensitive to sensory stress, respectively. Second, we explore scenarios where anti-predatory responses can either drive a strong or weak reduction in prey foraging. We find that sensory stress usually weakens trophic cascades except in scenarios where predators are relatively unaffected by sensory stress and the loss of anti-predatory responses does not affect prey foraging. The model finally suggests that “hydra effects” can manifest, whereby an increase in prey population occurs despite an increase in per capita predation. This last feature emerges due to the interaction between logistic growth of the basal resource and anti-predatory responses reducing the over-consumption of the basal resource.
When a yarmulke Stands for All Jews: Navigating Shifting Signs from Synagogue to School in Luxembourg
Authors: Badder Anastasia 
Published: January 2024

AbstractIn the lives of students in Luxembourg’s Liberal Jewish complementary school, flexibility and mobility are highly valued as key characteristics of modern living. Complementary school students feel they easily meet these criteria—they are multilingual, cosmopolitan, and their approach to Jewish life is flexible, and equally importantly, they look, dress, and comport themselves “like everyone else.” These factors are understood to facilitate multiple movements and belongings in the contemporary world. The students directly contrast their ways of being with those of more observant Jews whom they refer to as “religious”; the material, embodied, and visible nature of observant Jewish life is perceived to be an impediment to participation and success in the secular sphere. However, when Jewishness appears in these students’ secular school classrooms, it is most often represented by Orthodox-presenting men—often a man in a yarmulke. Further, these men and their yarmulkes are taken to represent all Jews, framed as a homogeneous group of religious adherents. For many complementary school students, these experiences can be jarring—they suddenly find themselves on the “wrong” side of the religious–secular divide and grouped together with those from whom they could not feel more distant. Drawing on ethnographic fieldwork and a material approach to religion, this article argues that the yarmulke comes to point to different levels and modes of observance and identities and enable different possible belongings in the secular public sphere as it travels across contexts that include different definitions of and attitudes toward religion and Jewishness.

Published: January 2024

AbstractCentella asiatica (CA) is one of the most popular traditional herbal medicines worldwide. It has been used for centuries in many countries, especially for curing skin damage, and is now applied to treat various human diseases. There are various types of triterpenoids from Centella asiatica, with four pentacyclic triterpenoids with the main properties being shown by four pentacyclic triterpenoids: asiaticoside, madecassoside, asiatic acid, and madecassic acid. These terpenoids have similar structures, however each has a slightly different properties. Asiaticoside, madecassoside, asiatic acid, and madecassic acid are synthesized through the isoprenoid pathway known as mevalonate pathway to produce hydrophobic triterpenoid structures (aglycone) which contain hydrophilic sugar chains (glycone). Furthermore, asiaticoside and madecassoside are distinguished by a glycone, and asiatic acid and madecassic acid are distinguished by a aglycone. These pentacyclic triterpenoids have a wide spectrum of beneficial effects and have been used as anti-inflammatories, skin wound treatments, scar treatments, and cosmetics agents. This review aimed to provide a description of the four compounds, of their structure, pharmacological properties, applications in the treatment of various diseases, known mechanisms of action, and commentary on industrial applications.

Abstract
Background
Blood transfusion reactions may have a negative impact on organ function. It is unknown whether this association holds true for acute kidney injury (AKI). Therefore, we conducted a cohort study to assess the association between transfusion reactions and the incidence of AKI and major adverse kidney events.

Methods
In this retrospective cohort study, we included patients who received transfusion of blood products during hospitalization at the Hospital Civil of Guadalajara. We analyzed them according to the development of transfusion reactions, and the aim was to assess the association between transfusion reactions and AKI during long-term follow-up.

Results
From 2017 to 2021, 81,635 patients received a blood product transfusion, and 516 were included in our study. The most common transfusion was red blood cell packaging (50.4%), fresh frozen plasma (28.7%) and platelets (20.9%); of the 516 patients, 129 (25%) had transfusion reactions. Patients who had transfusion reactions were older and had more comorbidities. The most common type of transfusion reaction was allergic reaction (70.5%), followed by febrile nonhemolytic reaction (11.6%) and anaphylactoid reaction (8.5%). Most cases were considered mild. Acute kidney injury was more prevalent among those who had transfusion reactions (14.7%) than among those who did not (7.8%), p =  < 0.01; those with AKI had a higher frequency of diabetes, vasopressors, and insulin use. Transfusion reactions were independently associated with the development of AKI (RR 2.1, p =  < 0.02). Major adverse kidney events were more common in those with transfusion reactions. The mortality rate was similar between subgroups.

Conclusion
In our retrospective cohort of patients who received blood product transfusions, 25% experienced transfusion reactions, and this event was associated with a twofold increase in the probability of developing AKI and some of the major adverse kidney events during long follow-up.

Equivalence and Insurance
Authors: van den Hurk Arthur 
Published: January 2024

AbstractThe concept of equivalence is present in various forms in the Solvency II framework, the EU prudential regulatory framework for insurance and reinsurance. While equivalence in Solvency II does not grant, or should not be equated to, market access for market participants that make use of the equivalence instruments within Solvency II, equivalence plays an important role in insurance, in particular in the solvency capital calculation at group level, in group supervision and for the recognition of reinsurance under Solvency II. The conclusion can be drawn that equivalence is an essential building block of the current framework. The application of equivalence in the framework and in practice is discussed in this contribution, and while the application might be complex, it is indispensable. At the same time, other mechanisms, either within the Solvency II framework or more broadly at international level, influence the current state and might affect the evolution of equivalence going forward. While, inherently, there is a political component to equivalence as well, the instruments remain firmly based in (detailed) Solvency II rules and are applied accordingly in practice.
The chemical impact of oil fluids in the morphology and thermal properties of the polyamide 11 used in flexible lines

Published: January 2024

AbstractAs the polyamide 11 (PA11) present in flexible pipes for oil prospection is used, it also reacts with the fluid components in the oil so that not only the morphology of the polymer changes but also its properties. To see the extent of these chemical modifications and how they changed the original material, different techniques were employed, such as ATR-FTIR, DSC, TGA, and Melt-flow index (MFI), while the original sample was cut in half to measure if the direct contact with the fluid had a huge chemical influence. The results indicate that the degree of chemical changes in the PA11 part that was in direct contact with the fluid was higher, translated into the appearance of different molecules in the FTIR spectra (such as ethers, carbonates, and alkenes). These changes were also consistent with higher degradation of this half, leading to a region of higher crystallinity, which impacted the overall thermal properties of the polymer.
A Pipe Dream Perspective on Totally Symmetric Self-Complementary Plane Partitions
Authors: Huang Daoji , Striker Jessica 
Published: January 2024

Abstract
We characterize totally symmetric self-complementary plane partitions (TSSCPP) as bounded compatible sequences satisfying a Yamanouchi-like condition. As such, they are in bijection with certain pipe dreams. Using this characterization and the recent bijection of Gao–Huang between reduced pipe dreams and reduced bumpless pipe dreams, we give a bijection between alternating sign matrices and TSSCPP in the reduced, 1432-avoiding case. We also give a different bijection in the 1432- and 2143-avoiding case that preserves natural poset structures on the associated pipe dreams and bumpless pipe dreams.
Judicial Guardians: Court-Curbing Bills, the Supreme Court, and Judicial Review
Authors: Hager Lisa , Uribe-McGuire Alicia 
Published: January 2024

AbstractPrevious studies show that Supreme Court justices defer to congressional preferences by striking down fewer Acts of Congress to restore the judiciary’s institutional legitimacy following the introduction of court-curbing bills. This assumes the Supreme Court acts as a guardian of the entire judiciary, but prior work has not explicitly tested this. We create a theory of “guardian” behavior and test the likelihood that the Court engages in this behavior following the introduction of court-curbing bills. We find that the Supreme Court actively corrects lower court instances of judicial review, a stronger response than previously suggested.
Musical convergence and divergence in occupied İstanbul, 1918–1923
Authors: MacArthur-Seal Daniel-Joseph 
Published: January 2024

AbstractThe Allied occupation of İstanbul after World War I had a transformative impact on the city’s musical entertainment sector. The arrival of large numbers of military personnel created additional demand for music halls, cabarets, cafe-chantants, and concert venues. Servicemen’s musical preferences were catered for by resident İstanbulites and others who found refuge in the city, creating opportunities for musicians and entertainment entrepreneurs to benefit from new and existing patrons. This buoyant market was further harnessed for charitable causes directed at new categories of people in need. The distinct political climate introduced with occupation also made its mark on musical performance, with nationalist and socialist groups using concerts to promote messages of salvation. The end of the occupation led to the dispersal of these musicians to new locations, such as the new Republican capital of Ankara, which attracted talents intent on staying in Turkey, and Athens and Thessaloniki, which received Greek Orthodox musicians fleeing the new Turkish nationalist regime, and still further afield. Using British, French, and Ottoman government documents, memoirs, and newspapers, the article investigates this process of musical convergence and divergence and analyses the local and global impact of the aural encounters of this overlooked period in İstanbul’s cultural history.
Protein structures unravel the signatures and patterns of deep time evolution
Authors: Harish Ajith 
Published: January 2024

Abstract
The formulation and testing of hypotheses using ‘big biology data’ often lie at the interface of computational biology and structural biology. The Protein Data Bank (PDB), which was established about 50 years ago, catalogs three-dimensional (3D) shapes of organic macromolecules and showcases a structural view of biology. The comparative analysis of the structures of homologs, particularly of proteins, from different species has significantly improved the in-depth analyses of molecular and cell biological questions. In addition, computational tools that were developed to analyze the ‘protein universe’ are providing the means for efficient resolution of longstanding debates in cell and molecular evolution. In celebrating the golden jubilee of the PDB, much has been written about the transformative impact of PDB on a broad range of fields of scientific inquiry and how structural biology transformed the study of the fundamental processes of life. Yet, the transforming influence of PDB on one field of inquiry of fundamental interest—the reconstruction of the distant biological past—has gone almost unnoticed. Here, I discuss the recent advances to highlight how insights and tools of structural biology are bearing on the data required for the empirical resolution of vigorously debated and apparently contradicting hypotheses in evolutionary biology. Specifically, I show that evolutionary characters defined by protein structure are superior compared to conventional sequence characters for reliable, data-driven resolution of competing hypotheses about the origins of the major clades of life and evolutionary relationship among those clades. Since the better quality data unequivocally support two primary domains of life, it is imperative that the primary classification of life be revised accordingly.
