On the emission-path dependency of the efficiency of ocean alkalinity enhancement
Authors: Schwinger Jörg , Bourgeois Timothée , Rickels Wilfried 
Published: June 2024

Abstract
Ocean alkalinity enhancement (OAE) deliberately modifies the chemistry of the surface ocean to enhance the uptake of atmospheric CO2. The chemical efficiency of OAE (the amount of CO2 sequestered per unit of alkalinity added) depends, among other factors, on the background state of the surface ocean, which will significantly change until the end of this century and beyond. Here, we investigate the consequences of such changes for the long-term efficiency of OAE. We show, using idealized and scenario simulations with an Earth system model, that under doubling (quadrupling) of pre-industrial atmospheric CO2 concentrations, the simulated mean efficiency of OAE increases by about 18% (29%) from 0.76 to 0.90 (0.98). We find that only half of this effect can be explained by changes in the sensitivity of CO2 sequestration to alkalinity addition itself. The remainder is due to the larger portion of anthropogenic emissions taken up by a high-alkalinity ocean. Importantly, both effects are reversed if atmospheric CO2 concentrations were to decline due to large-scale deployment of land-based (or alternative ocean-based) carbon dioxide removal (CDR) methods. By considering an overshoot pathway that relies on large amounts of land-based CDR, we demonstrate that OAE efficiency indeed shows a strong decline after atmospheric CO2 concentrations have peaked. Our results suggest that the assumption of a constant, present-day chemical efficiency of OAE in integrated assessment modeling and carbon credit assignments could lead to economically inefficient OAE implementation pathways.
Constructive plaquette compilation for the parity architecture
Authors: ter Hoeven Roeland , Niehoff Benjamin E , Sudhir Kale Sagar , Lechner Wolfgang 
Published: June 2024

Abstract
Parity compilation is the challenge of laying out the required constraints for the parity mapping in a local way. We present the first constructive compilation algorithm for the parity architecture using plaquettes for arbitrary higher-order optimization problems. This enables adiabatic protocols, where the plaquette layout can natively be implemented, as well as fully parallelized digital circuits. The algorithm builds a rectangular layout of plaquettes, where in each layer of the rectangle at least one constraint is added. The core idea is that each constraint, consisting of any qubits on the boundary of the rectangle and some new qubits, can be decomposed into plaquettes with a deterministic procedure using ancillas. We show how to pick a valid set of constraints and how this decomposition works. We further give ways to optimize the ancilla count and show how to implement optimization problems with additional constraints.
Collective biphoton temporal waveform of photon-pair generated from Doppler-broadened atomic ensemble
Authors: Kim Heewoo , Jeong Hansol , Moon Han Seb 
Published: June 2024

Abstract
Photonic quantum states generated from atomic ensembles will play important roles in future quantum networks and long-distance quantum communication because their advantages, such as universal identity and narrow spectral bandwidth, are essential for quantum nodes and quantum repeaters based on atomic ensembles. In this study, we report the collectively coherent superposition of biphoton wavefunction emitted from different velocity classes in a Doppler-broadened cascade-type atomic ensemble. We experimentally demonstrate that the three times difference of temporal width of both biphoton temporal waveforms varies dependent on the wavelengths of the signal and idler photons from both 6S1/2–6P3/2–6D5/2 and –8S1/2 transitions of 133Cs, corresponding to the idler and signal wavelengths of 852 nm–917 nm and 852 nm–795 nm, respectively. Our results help understand the characteristics of biphoton sources from a warm atomic ensemble and can be applied to long-distance quantum networks and practical quantum repeaters based on atom–photon interactions.
Embedded components design strategy framework for fused deposition modeling system
Authors: Sharum Mohd Afiq , Rajendran Thavinnesh Kumar , Maidin Shajahan , Ismail Shafinaz 
Published: June 2024

Abstract
This paper proposed a framework for 3D printing of embedded objects specifically for the Fused Deposition Modeling (FDM) system. The main problem revolves around the difficulty of the additive manufacturing process to fully manufacture a product that can be used immediately after the printing process, thus creating the need for embedded component design to be utilized in the process. The framework was utilized to reduce components and assemblies to improve product design. To ensure environmental sustainability, the framework emphasizes materials used to make recyclable items. Design Process Flow, Design Knowledge, Key Enabling Technologies, and Design Application were used to create a four-layered design framework to tackle embedded product design challenges. The framework’s robustness and effectiveness were compared using three case studies: electric shaver, remote control and nintendo switch. The framework proposed a blade-interchangeable product for the electric shaver. In the second case study (remote control) the cover’s flexibility with similar sizes makes it reusable. In the third case study (nintendo switch), every part is interchangeable with numerous styles and designs, allowing the user to autonomously change to the desired pattern without external support. With its various features, the framework shows potential in reducing development time, cost, and resources to aid the embedded component design strategy and printing for the FDM process.
Teaching Honesty as a Part of Teaching Dissent
Authors: Stitzlein Sarah M 
Published: June 2024

Abstract
This chapter responds to an uptick in political dissent in recent years, especially among youth and populists. While dissent is a valuable component of ensuring quality life within a democracy, dissent cannot be done well if it does not emphasize truth-telling and truth-seeking as citizens navigate conflicting beliefs, practices, and policies. This chapter showcases how pragmatist classroom inquiry works against populist dichotomous groupings of “the people” versus “the elite,” because they prevent us from functioning smoothly together. Epistemic blind spots result when we are unable to see a situation from a competing perspective and are unwilling to attend to dissenting views raised by “the other side.” Building on philosophies of agonism, it describes how students should learn to engage as adversaries rather than as enemies, even when starting from places of conflict that are common in our world today.
The Form of Memory: Delacroix and the Sketchbook
Authors: Olmsted Jennifer W 
Published: June 2024

Abstract
For most of his career as an artist, Eugène Delacroix used designated sketchbooks during his travels, most famously on his trip to North Africa in 1832. While scholarship on Delacroix’s drawings often privileges their function as preparations for later paintings, closer scrutiny of his travel albums reveals his fascination with the temporal, experiential elements of drawing. In addition to using his sketchbooks as an aide-mémoire for later paintings, this essay proposes, Delacroix sought to fix memory and explore the essence of the fleeting moment within them. By examining the touristic and memorial aspects of his sketchbooks as they evolved over time, this essay shows how Delacroix negotiated the tension between the temporal and the material, between the sketch as physical record of lived experience and the sketch as talismanic performance against the loss of memory and the passing of time.
Early detection and diagnosis of cancer with interpretable machine learning to uncover cancer-specific DNA methylation patterns
Authors: Newsham Izzy , Sendera Marcin , Jammula Sri Ganesh , Samarajiwa Shamith A 
Published: June 2024

Abstract
Cancer, a collection of more than two hundred different diseases, remains a leading cause of morbidity and mortality worldwide. Usually detected at the advanced stages of disease, metastatic cancer accounts for 90% of cancer-associated deaths. Therefore, the early detection of cancer, combined with current therapies, would have a significant impact on survival and treatment of various cancer types. Epigenetic changes such as DNA methylation are some of the early events underlying carcinogenesis. Here, we report on an interpretable machine learning model that can classify 13 cancer types as well as non-cancer tissue samples using only DNA methylome data, with 98.2% accuracy. We utilize the features identified by this model to develop EMethylNET, a robust model consisting of an XGBoost model that provides information to a deep neural network that can generalize to independent data sets. We also demonstrate that the methylation-associated genomic loci detected by the classifier are associated with genes, pathways and networks involved in cancer, providing insights into the epigenomic regulation of carcinogenesis.
Variations in origin level of superior mesenteric artery, inferior mesenteric artery, and coeliac trunk in Indian population
Authors: Singh Mohit Kumar , Tibrewala Sunita , Achhapalia Yash , Chawda Pankti 
Published: June 2024

Abstract

Objective
The abdominal aorta is a continuation of the thoracic aorta and gives off the coeliac trunk, superior mesenteric artery, and inferior mesenteric artery. The focus of our study is to evaluate variations in the origin level in the coeliac trunk, superior mesenteric artery, inferior mesenteric artery, and aortic bifurcation in the Indian population and compare with various demographics.

Methods
The study was retrospective and the local ethics committee approval was taken before starting it. Three hundred patients who were more than 18 years of age and required contrast-enhanced CT studies were included in this. The vertebral origin level of the arteries from the abdominal aorta and aortic bifurcation level was analysed.

Results
The most common origin level of the coeliac trunk for both males and females was T12-L1 disc level. The most common origin level of the superior mesenteric artery was L1 upper level. The most common origin level of the inferior mesenteric artery was L3 upper level. The most common level of aortic bifurcation was L4 middle level. There was no statistical difference between the origin of any arteries in males and females in the Indian population.

Conclusion
As per our study of the Indian population and the published literature, it is realized that there are significant variations in the origins of the coeliac trunk, superior mesenteric artery, inferior mesenteric artery, and abdominal aorta bifurcation in different populations.

Advances in knowledge
This study elaborates on potential anatomical variations in the Indian population, particularly the Mumbai city population. Also, our study compares it to different countries’ data and their results in variations found in abdominal aorta branches.
Emergency umbilical hernia management: scoping review
Authors: Walshaw Josephine , Kuligowska Anna , Smart Neil J , Blencowe Natalie S , Lee Matthew J 
Published: June 2024

Abstract

Background
Umbilical hernias, while frequently asymptomatic, may become acutely symptomatic, strangulated or obstructed, and require emergency treatment. Robust evidence is required for high-quality care in this field. This scoping review aims to elucidate evidence gaps regarding emergency care of umbilical hernias.

Methods
EMBASE, MEDLINE and CENTRAL databases were searched using a predefined strategy until November 2023. Primary research studies reporting on any aspect of emergency umbilical hernia care and published in the English language were eligible for inclusion. Studies were excluded where emergency umbilical hernia care was not the primary focus and subsets of relevant data were unable to be extracted. Two independent reviewers screened abstracts and full texts, resolving disagreements by consensus or a third reviewer. Data were charted according to core concepts addressed by each study and a narrative synthesis was performed.

Results
Searches generated 534 abstracts, from which 32 full texts were assessed and 14 included in the final review. This encompassed 52 042 patients undergoing emergency umbilical hernia care. Most were retrospective cohort designs (11/14), split between single (6/14) and multicentre (8/14) with only one randomized trial. Most multicentre studies were from national databases (7/8). Themes arising included risk assessment (n = 4), timing of surgery (n = 4), investigations (n = 1), repair method (n = 8, four mesh versus suture; four laparoscopic versus open) and operative outcomes (n = 11). The most commonly reported outcomes were mortality (n = 9) and morbidity (n = 7) rates and length of hospital stay (n = 5). No studies included patient-reported outcomes specific to emergency umbilical hernia repair.

Conclusion
This scoping review demonstrates the paucity of high-quality data for this condition. There is a need for randomized trials addressing all aspects of emergency umbilical hernia repair, with patient-reported outcomes.
Anther wall and pollen development in Aspidosperma Mart & Zucc. (Apocynaceae)
Authors: Alves Daniela M , Souto Letícia S , Koch Ingrid 
Published: June 2024

Abstract
Apocynaceae is one of the richest flowering plant families, and the complexity of their reproductive structures and morphological diversity of the flowers has been considered central to understanding its evolutionary success and diversification. However, the diversity of its embryological characters is poorly known, especially in taxa that are early diverging in the family, such as the Aspidospermateae tribe. Moreover, the knowledge gap on early divergent taxa forbids the reconstruction of evolutionary trends in Apocynaceae. Here, we investigated the anther wall and pollen development of five species of Aspidosperma using conventional plant anatomy techniques. We found that the primary conditions for the Aspidosperma species are fibrous endothecium, middle layer, and secretory tapetum having one-layered and uninucleate cells, besides simultaneous cytokinesis. We also found pollen grains 4–6 colporate, alternately with pseudocolporate in all the species, with ridges formed by the thickened inequal deposition of the infratectum layer in the exine that delimits aperture regions. The differentiated deposition of exine confers a distinctive appearance to pollen grains and appears to be associated with the hydration/dehydration process during pollination. Similar deposition patterns have been identified in other genera within the tribe Aspidospermateae, suggesting that it may constitute a synapomorphy for the tribe.
Extreme range in adult body size reveals hidden trade-offs among sexually selected traits

Published: June 2024

Abstract
Sexually selected weapons used to monopolize mating opportunities are predicted to trade-off with traits used in competition for fertilization. Yet, the limited size range typically found among adults of a species often precludes clear comparisons between population-level and individual-level relative trait investment. The jousting weevil, Brentus anchorago (Coleoptera: Brentidae), varies more than 26-fold in body mass, which is among the most extreme adult body size ranges of any solitary terrestrial species. We reveal a trade-off at a population level: hypermetric scaling in male weapons (slope = 1.59) and a closely mirrored reversal in allocation to postcopulatory traits (slope = 0.54). Yet, at the individual level, we find the opposite pattern; males that invest relatively more in weapons for their size class also invest more in postcopulatory traits. Across 36 dung beetle and 41 brentine weevil species, we find the allometric slope explains more trait variation at larger body size ranges; in brentines, population-level scaling patterns become more detectable in species with a larger range in adult body size. Our findings reveal that population-level allometries and individual-level trade-offs can both be important in shaping relative trait allocation; we highlight that the adult body size range is rarely examined but may be integral to gaining a deeper understanding of trade-offs in reproductive allocation.
Unravelling the mechanisms of antibiotic and heavy metal resistance co-selection in environmental bacteria
Authors: Gillieatt Brodie F , Coleman Nicholas V 
Published: June 2024

Abstract
The co-selective pressure of heavy metals is a contributor to the dissemination and persistence of antibiotic resistance genes in environmental reservoirs. The overlapping range of antibiotic and metal contamination and similarities in their resistance mechanisms point to an intertwined evolutionary history. Metal resistance genes are known to be genetically linked to antibiotic resistance genes, with plasmids, transposons, and integrons involved in the assembly and horizontal transfer of the resistance elements. Models of co-selection between metals and antibiotics have been proposed, however, the molecular aspects of these phenomena are in many cases not defined or quantified and the importance of specific metals, environments, bacterial taxa, mobile genetic elements, and other abiotic or biotic conditions are not clear. Co-resistance is often suggested as a dominant mechanism, but interpretations are beset with correlational bias. Proof of principle examples of cross-resistance and co-regulation has been described but more in-depth characterizations are needed, using methodologies that confirm the functional expression of resistance genes and that connect genes with specific bacterial hosts. Here, we comprehensively evaluate the recent evidence for different models of co-selection from pure culture and metagenomic studies in environmental contexts and we highlight outstanding questions.
Cohort Differences in Physical Health and Disability in the United States and Europe
Authors: Gimeno Laura , Goisis Alice , Dowd Jennifer B , Ploubidis George B 
Published: June 2024

Abstract

Objectives
Declines in mortality have historically been associated with improvements in physical health across generations. While life expectancy in most high-income countries continues to increase, there is evidence that younger generations, particularly in the United States, are less healthy than previous generations at the same age. We compared generational trends in physical health in the United States, England, and continental Europe to explore whether other regions have experienced a similar pattern of worsening health across cohorts.

Methods
Using data from nationally representative studies of adults aged ≥50 years from the United States (Health and Retirement Study, n = 26,939), England (English Longitudinal Study of Ageing, n = 14,992) and 11 continental European countries (Survey of Health, Ageing and Retirement in Europe, n = 72,595), we estimated differences in the age-adjusted prevalence of self-reported chronic disease and disability and observer-measured health indicators across pseudo-birth cohorts (born &lt;1925, 1925–1935, 1936–1945, 1946–1954, 1955–1959).

Results
Age-adjusted prevalence of doctor-diagnosed chronic disease increased across successive cohorts in all regions. Trends in disability prevalence were more regionally varied. Still, in both the United States and Europe, we observed a structural break in disability trends, with declines observed in prewar cohorts slowing, stalling, or reversing for cohorts born since 1945.

Discussion
In all regions, we found evidence for worsening health across cohorts, particularly for those born since 1945. While more chronic disease in younger cohorts need not necessarily translate to worse quality of life or higher rates of functional limitation, there is some suggestion that worsening chronic disease morbidity may be spilling over into worsening disability.

Published: June 2024

Abstract

Background
This study addresses the importance of precise referencing in 3-dimensional (3D) plant phenotyping, which is crucial for advancing plant breeding and improving crop production. Traditionally, reference data in plant phenotyping rely on invasive methods. Recent advancements in 3D sensing technologies offer the possibility to collect parameters that cannot be referenced by manual measurements. This work focuses on evaluating a 3D printed sugar beet plant model as a referencing tool.

Results
Fused deposition modeling has turned out to be a suitable 3D printing technique for creating reference objects in 3D plant phenotyping. Production deviations of the created reference model were in a low and acceptable range. We were able to achieve deviations ranging from −10 mm to +5 mm. In parallel, we demonstrated a high-dimensional stability of the reference model, reaching only ±4 mm deformation over the course of 1 year. Detailed print files, assembly descriptions, and benchmark parameters are provided, facilitating replication and benefiting the research community.

Conclusion
Consumer-grade 3D printing was utilized to create a stable and reproducible 3D reference model of a sugar beet plant, addressing challenges in referencing morphological parameters in 3D plant phenotyping. The reference model is applicable in 3 demonstrated use cases: evaluating and comparing 3D sensor systems, investigating the potential accuracy of parameter extraction algorithms, and continuously monitoring these algorithms in practical experiments in greenhouse and field experiments. Using this approach, it is possible to monitor the extraction of a nonverifiable parameter and create reference data. The process serves as a model for developing reference models for other agricultural crops.
