Geometric tracking on 𝒮3 based on sliding mode control
Authors: Espíndola Eduardo , Tang Yu 
Published: June 2024

AbstractAttitude tracking on the unit sphere of dimension 3 based on sliding mode is considered in this article. The tangent bundle of Lagrangian dynamics that describes the rotational motion of a rigid body is first equipped with the structure of a Lie group, then a sliding subgroup emerged on it is defined. Next, a sliding‐mode controller is designed for attitude tracking that relies on an intrinsic error defined on the Lie group. Almost global asymptotic stability of the closed loop is demonstrated using the Lyapunov analysis. Comparisons of the proposed geometric sliding mode controller designed on the nonlinear manifold with one designed in the Euclidean space showed that under the same working conditions the former is more energy efficient, more robust to measurement noises, and has a shorter and smoother transient response.
Mountain search and recovery: An unmanned aerial vehicle deployment case study and analysis
Authors: Schomer Nathan L. , Adams Julie A. 
Published: June 2024

AbstractMountain search and rescue (MSAR) seeks to assist people in extreme remote environments. This method of emergency response often relies on crewed aircraft to perform aerial visual search. Many MSAR teams use low‐cost, consumer‐grade unmanned aerial vehicles (UAVs) to augment the crewed aircraft operations. These UAVs are primarily developed for aerial photography and lack many features critical (e.g., probability‐prioritized coverage path planning) to support MSAR operations. As a result, UAVs are underutilized in MSAR. A case study of a recent mountain search and recovery scenario that did not use, but may have benefited from, UAVs is provided. An overview of the mission is augmented with a subject matter expert‐informed analysis of how the mission may have benefited from current UAV technology. Lastly, mission relevant requirements are presented along with a discussion of how future UAV development can seek to bridge the gap between state‐of‐the‐art robotics and MSAR.

Published: June 2024

Abstractα‐Sn, a new elemental topological quantum material, has drawn substantial attention lately. Unique transport properties and intriguing spintronics applications of α‐Sn are demonstrated, resurrecting this material from its notorious “tin pest” infamy. With a diamond cubic crystal structure, group‐IV α‐Sn holds the potential for integrated topological quantum devices on Si. However, directly growing α‐Sn on Si is still challenging due to the ≈20% lattice mismatch. Here, a new method is demonstrated to grow 200 nm‐thick α‐Sn microstructures on a 2 nm‐thick Ge seed layer on Si substrate by physical vapor deposition. In situ Raman spectroscopy reveals that the as‐deposited β‐Sn melts upon rapid thermal annealing at 350–450 °C and solidifies to α‐Sn after cooling back to room temperature, seeded by heterogeneous nucleation on the Ge layer. Cooling condition and HCl etching are tuned to achieve phase‐pure α‐Sn microstructures toward quantum devices. Approximately 1 at.% Ge is alloyed into α‐Sn due to diffusion from the Ge seed layer, which helps stabilize α‐Sn thermodynamically to facilitate device processing. A compressive strain is incorporated into these α‐Sn microstructures, making them 3D topological Dirac semimetals for integrated quantum devices on Si.
Nearest‐neighbor, BERT‐based, scalable clone detection: A practical approach for large‐scale industrial code bases

Published: June 2024

AbstractHidden code clones negatively impact software maintenance, but manually detecting them in large codebases is impractical. Additionally, automated approaches find detection of syntactically‐divergent clones very challenging. While recent deep neural networks (for example BERT‐based artificial neural networks) seem more effective in detecting such clones, their pairwise comparison of every code pair in the target system(s) is inefficient and scales poorly on large codebases. We present SSCD, a BERT‐based clone detection approach that targets high recall of Type 3 and Type 4 clones at a very large scale (in line with our industrial partner's requirements). It computes a representative embedding for each code fragment and finds similar fragments using a nearest neighbor search. Thus, SSCD avoids the pairwise‐comparison bottleneck of other neural network approaches, while also using a parallel, GPU‐accelerated search to tackle scalability. This article describes the approach, proposing and evaluating several refinements to improve Type 3/4 clone detection at scale. It provides a substantial empirical evaluation of the technique, including a speed/efficacy comparison of the approach against SourcererCC and Oreo, the only other neural‐network approach currently capable of scaling to hundreds of millions of LOC. It also includes a large in‐situ evaluation on our industrial collaborator's code base that assesses the original technique, the impact of the proposed refinements and illustrates the impact of incremental, active learning on its efficacy. We find that SSCD is significantly faster and more accurate than SourcererCC and Oreo. SAGA, a GPU‐accelerated traditional clone detection approach, is a little better than SSCD for T1/T2 clones, but substantially worse for T3/T4 clones. Thus, SSCD is both scalable to industrial code sizes, and comparatively more accurate than existing approaches for difficult T3/T4 clone searching. In‐situ evaluation on company datasets shows that SSCD outperforms the baseline approach (CCFinderX) for T3/T4 clones. Whitespace removal and active learning further improve SSCD effectiveness.
Unveiling the aftermath of conflict and herbarium specimens’ loss: Typifications of species described by Pohl within the Neotropical genus Vellozia
Authors: Lopes Jenifer C. , Magri Renato A. , Prado Jefferson 
Published: June 2024

AbstractJohann Emanuel Pohl (1782–1834) was a Bohemian‐born Austrian botanist who, together with Johann Baptist von Spix and Carl Friedrich Philipp von Martius, traveled to Brazil from 1817 to 1821. He described several new plant species from Brazil, including those in the genus Vellozia (Velloziaceae). The material analyzed by Pohl was deposited mainly at herbarium W; however, part of the collection was destroyed by war accidents, including most of the types of Vellozia. Vellozia is a Neotropical genus with its main distribution in the Brazilian vegetation named campos rupestres. Vellozia is among the most abundant and species‐rich vascular‐plant genera in the campos rupestres with 125 recognized species. Pohl described 14 new species of Vellozia. We designate lectotypes for the names V. gardneri (a synonym of V. glauca), V. graminea, V. phalocarpa, V. pusilla, and V. triquetra.
Traumatic nasogastric intubation as a suspected cause of laryngeal obstruction in a horse recovering from emergency laparotomy
Authors: Gavet Morgane , Junot Stéphane 
Published: June 2024

AbstractAn 18‐year‐old mare, admitted for colic, underwent an exploratory laparotomy for right dorsal colon displacement. During recovery from anaesthesia, a severe acute onset laryngeal obstruction occurred at standing, requiring orotracheal re‐intubation, which relieved the obstruction. This was followed by secondary pulmonary oedema, treated with furosemide (2 mg/kg intravenously) and oxygen. At re‐extubation, attempted 30 minutes later, the horse re‐obstructed immediately and collapsed, prompting an emergency tracheostomy. Furosemide (2 mg/kg intravenously) and dexamethasone (0.1 mg/kg intravenously) were also administered. The horse stood up thereafter with a patent airway. In the history, to note, nasogastric intubation was particularly difficult at admission, and was identified as a potential cause of laryngeal trauma that may have precipitated laryngeal obstruction due to severe local inflammation. Dynamic laryngeal collapse probably also played a role due to high inspiratory negative pressure generated at the precise timing of standing, similar to exercise.
Microparticles of arsenic water treatment media and water softener resin observed in treated water at private wells
Authors: Rockafellow‐Baldoni Megan , Spayd Steven E. , Robson Mark G. 
Published: June 2024

AbstractObservation of arsenic water treatment adsorption media in the treated water of several homes with high arsenic private wells led to the hypothesis that treatment media was escaping the treatment systems and entering the plumbing and drinking water. Our research at 62 homes identified that microparticles of arsenic water treatment media and/or water softener resin had escaped the treatment system in 71% of the homes. This is a potential health hazard as ingesting arsenic treatment media or water softener resin may lead to an elevated ingestion exposure to arsenic and other contaminants. Potential causes of media escape from the treatment systems include media observed to be smaller in size than specifications and media breaking into smaller pieces. One interim solution to media escape is installation of a post‐treatment sediment filter. New developments in media durability or treatment system design and maintenance may be needed to prevent media escaping into drinking water.Practitioner Points
Arsenic in private wells is often treated with point‐of‐entry whole house adsorption systems.
Arsenic adsorption treatment media and/or water softener resin was observed in treated water at 44 of 62 homes inspected.
Water treatment media escaping into treated water is a potential hazardous exposure pathway.
Potential causes and solutions are discussed.

AbstractFrom birth, I grew up on Wiradyuri Country, and I am endlessly grateful to my grandfather, Budyaan Wilfred Johnson, for teaching me many things, including the language of our Ancestors. He was a strong cultural leader and a strategic genius who had a long-term vision for the recovery of his people. Despite being jailed for speaking to me in Wiradyuri, he went on to teach me (and my brother Cecil) away from the settler colonial authorities who would incarcerate him and remove us from our family. Today, our language is being used to quietly heal and rebuild the lives of our people so they can once again care for Country and raise strong, healthy, vibrant families.
New Pathway to Adolescent Wellbeing: The Case for Online Special Religious Education in Public Schools
Authors: Khaled Leila 
Published: June 2024

AbstractSpecial Religious Education (SRE) provides an opportunity for students of faith backgrounds to foster their religious identity and spiritual health. However, many students currently have no access to weekly onsite SRE. This research plans on introducing and evaluating a weekly online SRE intervention in public high schools for a minority cohort—Muslim SRE. The theory of practice architectures (TPA) frames the study. This chapter makes a case for online SRE by presenting the study’s underpinnings using relevant literature on adolescent wellbeing, religion, and education. This study intends to inform policymakers and practitioners arguing for contemporary ways to improve and widen access to SRE. Online SRE could reveal a large-scale, cost-effective, and practical educational measure for enhancing the wellbeing of adolescents of faith backgrounds in public schools, even for those considered at-risk (In this chapter, SRE is also referred to as religious education. This is not to be confused with General Religious Education—the inclusive teaching about different religions.).
Education that Makes Life Manageable, Comprehensible, and Meaningful: Experiences of the Monash Access Program, a University Alternative Entry Pathway
Authors: Reimer Kristin Elaine 
Published: June 2024

AbstractAlthough formal education is arguably a powerful force for good, the experience of schooling can feel disempowering and disheartening to some young people. This chapter listens to students who have had negative experiences of schooling and entered university through an alternative pathway. Seven students who graduated from the Monash Access Program (MAP) in four different years share their insights into formal education. MAP is an intentionally relational program, grounded in critical praxis, for mature-aged students who have experienced educational disruptions. By drawing on Antonovsky’s concept ofsense of coherenceto understand the students’ insights, this study shows how MAP helped students to make sense of education as manageable, comprehensible, and meaningful. These students, who have had both educational disadvantage (prior to university) and educational advantage (through MAP), offer their perspectives into education’s role in helping us to live well and to create a world worth living in for all. With this study, after listening to the students, I argue that formal education can provide us with experiences of manageability, comprehensibility, and meaningfulness in order to create a world where we are able to thrive individually and collectively.
Exploring “Living Well” Through Children’s Play
Authors: Kaukko Mervi , Haswell Nick , Wilkinson Jane 
Published: June 2024

AbstractThis chapter considers how “living well in a world worth living in” is imagined, replicated and lived in children’s free play. Drawing primarily on video data collected by 21 young migrant and refugee background primary school students in Finland and Australia, we consider what children’s play can reveal about a just, equitable and fair world in the present and in future, and how schools can support its development by providing the needed cultural-discursive, material-economic, and social-political arrangements for play. Our chapter shows that as children play, they not only create, simulate, and negotiate between themselves an imagined, future-oriented world worth living in for all, but also, through the real collaboration, empathy and care they develop and practise together, they bring that world into being.
Brassica rapa CURLY LEAF is a major H3K27 methyltransferase regulating flowering time
Authors: Poza-Viejo Laura , Payá-Milans Miriam , Wilkinson Mark D. , Piñeiro Manuel , Jarillo José A. , Crevillén Pedro 
Published: June 2024

Abstract
Main conclusion
In Brassica rapa, the epigenetic modifier BraA.CLF orchestrates flowering by modulating H3K27me3 levels at the floral integrator genes FT, SOC1, and SEP3, thereby influencing their expression.

Abstract
CURLY LEAF (CLF) is the catalytic subunit of the plant Polycomb Repressive Complex 2 that mediates the trimethylation of histone H3 lysine 27 (H3K27me3), an epigenetic modification that leads to gene silencing. While the function of CURLY LEAF (CLF) has been extensively studied in Arabidopsis thaliana, its role in Brassica crops is barely known. In this study, we focused on the Brassica rapa homolog of CLF and found that the loss-of-function mutant braA.clf-1 exhibits an accelerated flowering together with pleiotropic phenotypic alterations compared to wild-type plants. In addition, we carried out transcriptomic and H3K27me3 genome-wide analyses to identify the genes regulated by BraA.CLF. Interestingly, we observed that several floral regulatory genes, including the B. rapa homologs of FT, SOC1 and SEP3, show reduced H3K27me3 levels and increased transcript levels compared to wild-type plants, suggesting that they are direct targets of BraA.CLF and key players in regulating flowering time in this crop. In addition, the results obtained will enhance our understanding of the epigenetic mechanisms regulating key developmental traits and will aid to increase crop yield by engineering new Brassica varieties with different flowering time requirements.

Iodine-125 seed inhibits proliferation and promotes apoptosis of cholangiocarcinoma cells by inducing the ROS/p53 axis
Authors: Kang Fuping , Wu Jing , Hong Li , Zhang Peng , Song Jianjun 
Published: June 2024

AbstractWith advances in radioactive particle implantation in clinical practice, Iodine-125 (125I) seed brachytherapy has emerged as a promising treatment for cholangiocarcinoma (CCA), showing good prognosis; however, the underlying molecular mechanism of the therapeutic effect of 125I seed is unclear. To study the effects of 125I seed on the proliferation and apoptosis of CCA cells. CCA cell lines, RBE and HCCC-9810, were treated with reactive oxygen species (ROS) scavenger acetylcysteine (NAC) or the p53 functional inhibitor, pifithrin-α hydrobromide (PFTα). Cell counting kit-8 (CCK-8) assay, 5-bromo-2-deoxy-uridine (BrdU) staining, and terminal deoxynucleotidyl transferase (TdT)-mediated dUTP nick end labeling (TUNEL) assay and flow cytometry assay were performed to test the radiation-sensitivity of 125I seed toward CCA cells at different radiation doses (0.4 mCi and 0.8 mCi). 2,7-dichlorofluorescein diacetate (DCF-DA) assay, real-time quantitative polymerase chain reaction (RT-qPCR), and western blot analysis were performed to assess the effect of 125I seed on the ROS/p53 axis. A dose-dependent inhibitory effect of 125I seeds on the proliferation of CCA cells was observed. The 125I seed promoted apoptosis of CCA cells and induced the activation of the ROS/p53 pathway in a dose-dependent manner. NAC or PFTα treatment effectively reversed the stimulatory effect of 125I seed on the proliferation of CCA cells. NAC or PFTα suppressed apoptosis and p53 protein expression induced by the 125I seed. 125I seed can inhibit cell growth mainly through the apoptotic pathway. The mechanism may involve the activation of p53 and its downstream apoptotic pathway by up-regulating the level of ROS in cells.
Altruistic behavior and international environmental agreements: a differential game approach
Authors: Sacco Armando 
Published: June 2024

AbstractIn the last three decades International Environmental Agreements (IEAs) have been widely analyzed. Classic models predict that only coalitions formed by a few countries can be stable, generating a rich literature devoted to solving the small coalition puzzle. The fundamental idea behind the great part of the literature is that players are selfish: to achieve a large stable coalition it is necessary to design an agreement that includes a credible system of incentives or punishments. The aim of this model is to study the effects, on equilibrium strategies and on the stability of an IEA, of players that do not look only at their own interests, but that take care of the wellness of the other players in coalition. Following the approach of the Paris Agreement in 2015, countries that join the coalition do not decide emissions collectively, but each of them sets their own emissions. The model is the usual two-step game: first the players have to choose whether they want to join the coalition or not, in the second step they solve a Nash differential game to find the optimal emissions. The stability of the coalition is studied in two cases: (i) with the classic internal and external stability, (ii) defining an altruistic stability condition.
Development support as education aid or labor trade? South Korean nurses in West Germany (1965–1976)
Authors: Yu Jinyoung , Seo Jungwook 
Published: June 2024

AbstractOver 10,000 South Korean nurses were sent to West Germany in the 11-year period between 1965 and 1976. It is known that they were dispatched because of South Korea’s need for capital and expertise after the Korean War (1950–1953). To assist in this endeavor, West Germany helped South Korea through development support (educational aid). However, Korean nurses were not simply trainees since they had received a proper education and qualifications. Thus, this “educational aid” could critically be termed little more than “labor trade” because the highly educated nurses were forced to take work with lower wages than their background warranted.
The experience of men with breast cancer: a metasynthesis
Authors: Guarinoni Milena Giovanna , Motta Paolo Carlo 
Published: June 2024

Abstract
Aim
To assess men’s experiences when diagnosed with breast cancer.
Subject and Methods: The breast is a symbol of femininity. Therefore, it is no surprise that studies on women’s experiences with breast cancer predominate in the literature. Because breast cancer accounts for just 1% of all cancers among men, it is often overlooked. Nevertheless, it accounts for proportionately more deaths than penile or testicular cancer. Five major databases were queried in December 2022 to review primary studies with qualitative design.

Results
Of the 206 articles selected and screened, eight met the inclusion criteria. Three highlighting men’s experience with stigmatisation and their need to be taken into consideration, even through information not solely aimed at women, are from a German study conducted between 2018 and 2020. Three from the UK between 2003 and 2007, also emphasise the stigma and the need for more information directed specifically at men. The study from the United States points out that men who receive treatment in women’s care spaces experience feelings of inadequacy. Last, a recent Israeli paper (2021) describes how men conceal the disease to avoid the stigma altogether.

Conclusion
The paper examines the paltry, recent research on men’s emotional experience with breast cancer, which is culturally relegated to women. However, a clear need emerges for more attention to be paid to addressing communications and relations for these male patients as well.
