Decomposition methods for multi-horizon stochastic programming
Authors: Zhang Hongyu , Grossmann Ignacio E. , Tomasgard Asgeir 
Published: May 2024

AbstractMulti-horizon stochastic programming includes short-term and long-term uncertainty in investment planning problems more efficiently than traditional multi-stage stochastic programming. In this paper, we exploit the block separable structure of multi-horizon stochastic linear programming, and establish that it can be decomposed by Benders decomposition and Lagrangean decomposition. In addition, we propose parallel Lagrangean decomposition with primal reduction that, (1) solves the scenario subproblems in parallel, (2) reduces the primal problem by keeping one copy for each scenario group at each stage, and (3) solves the reduced primal problem in parallel. We apply the parallel Lagrangean decomposition with primal reduction, Lagrangean decomposition and Benders decomposition to solve a stochastic energy system investment planning problem. The computational results show that: (a) the Lagrangean type decomposition algorithms have better convergence at the first iterations to Benders decomposition, and (b) parallel Lagrangean decomposition with primal reduction is very efficient for solving multi-horizon stochastic programming problems. Based on the computational results, the choice of algorithms for multi-horizon stochastic programming is discussed.

AbstractPollen, particularly from the Ambrosia genus, plays a pivotal role in triggering allergic rhinoconjunctivitis symptoms. This review delves into the global background of Ambrosia, focusing on its origins, invasive potential, and spread to South America. The ecological niche for Ambrosia species is explored, emphasizing its stability globally but exhibiting unique and dynamic features in South America. Information on Ambrosia pollen concentration in South America is summarized, revealing varying levels across countries. The establishment of new aerobiology stations, as highlighted in the latest findings, contributes valuable data for understanding allergen risk management in the region. The health perspective addresses the rise in allergic diseases due to climate change, emphasizing the need for continuous monitoring, especially in South America. Agricultural damage inflicted by Ambrosia is discussed, emphasizing its invasive potential, high seed production, and negative impact on crops, forage quality, and livestock. The review also positions Ambrosia as a marker of climate change, discussing the effects of global warming on pollen seasons, concentrations, and allergenic characteristics. The importance of expanding aerobiology stations in South America is underscored, requiring collaborative efforts from government, scientific societies, and academic institutions. The review concludes by advocating for increased monitoring to address potential challenges posed by Ambrosia, offering a basis for tailored interventions and future research in South American regions.

AbstractAgroforestry systems promise a high multifunctionality providing cash and subsistence yields as well as other ecosystem services. Such land systems may be particularly promising for smallholders in tropical landscapes due to high labour intensity and productivity on limited land. Focusing on Madagascar, we here describe the history of agroforestry in the country and review the current literature on agroforestry outcomes as well as factors promoting and hindering agroforest establishment and maintenance. From this, we discuss the potential future of agroforestry in Madagascar. Historically, many crops farmed today in agroforestry systems were originally introduced as plantation crops, mostly in the nineteenth century. Since then, people co-opted these crops into mixed agroforestry systems, often focusing on clove, vanilla, coffee, or cocoa in combination with fruit trees or, for clove, with livestock. Other crops are also integrated, but shares are comparatively low. Overall, 27.4% of Malagasy exports are crops typically farmed in agroforestry systems, providing income for at least 500,000 farmers. Outcomes of agroforestry for biodiversity and ecosystem services are commonly researched, showing benefits over annual crops and monocultures. Social-economic outcomes, including yields, are more scarcely researched, but findings point towards financial benefits for smallholder farmers and a sense of community and collective memory. However, findings emphasize that research gaps remain in terms of geographic and crop coverage, also for ecological outcomes. Looking to the future, we highlight the need to overcome hurdles such as land tenure insecurity, financial barriers to implementation, and unstable value chains to scale agroforestry in Madagascar to the benefit of multifunctional land systems and human wellbeing.
Beyond access: (re)designing archival guides for changing landscapes
Authors: Jones Mike , Taylor Rebe 
Published: May 2024

AbstractIn 2013, the authors of this article and their colleague Gavan McCarthy publishedStories in Stone: an annotated history and guide to the collections of Ernest Westlake (1855–1922).The guide provided contextual information and digital access to the entire paper archives relating to the three large stone collections formed by Westlake during his lifetime: French and English geological specimens housed in the Oxford University Museum of Natural History from 1924, and a collection of Tasmanian Aboriginal stone tools stored in the Pitt Rivers Museum since 1923. The Tasmanian collections, formed by Westlake from 1908 to 1910, are highly significant to the Palawa (or Pakana or Tasmanian Aboriginal) community because they include objects made by ancestors, and words spoken by ancestors to Westlake and recorded in his field notebooks.Stories in Stonewas created to improve access to Westlake’s Tasmanian collections for the Palawa community with whom author Rebe Taylor had worked closely since 1999. Nonetheless, the structural and technical design ofStories in Stonewas not Palawa-led. It was driven by Australian and international archiving standards; by stipulations set out by the collecting institutions; and by the stories of collecting and subsequent scholarship on the collections. In 2023,Stories in Stoneis offline, and the authors are planning a relaunch. This time they aim to reach beyond their original aim of providing archival accesstothe Palawa community, and workwithPalawa community to co-designhowthat access is delivered. This consultative work will be done at the University of Tasmania, where Palawa advisors and other Indigenous scholars have been integral to developing international Indigenous data sovereignty principals. This article precedes those formal discussions and thus offers a timely reflection on the original aims and design ofStories in Stoneas well as an extensive analysis of broader changes in the management and dissemination of First Nations collections and culture. Such changes include: international human rights frameworks; movements supporting data and archival sovereignty; co-designed archival technologies; and increased focus on archives asprocessnot merelyproduct. These developments will lay the foundations for the next version ofStories in Stone, which aims to go beyond access, scholarship, and standards by helping to facilitate First Nations’ aspirations for dignity, sovereignty, and self-determination.
The Media and Sexual Violence Among Adolescents: Findings from a Qualitative Study of Educators Across Vietnam

Published: May 2024

AbstractGrowing access to technology and media has presented new avenues of influence on youth attitudes and norms regarding sexuality and sexual violence, as well as new technological pathways through which to perpetrate sexual violence. The aim of this research was to understand contextual influences on and needs for scale-up of sexual violence prevention programming in the media-violence context of Vietnam. We conducted 45 interviews with high school teachers (n = 15), university lecturers (n = 15), and affiliates from youth-focused community service organizations (n = 15) from across Vietnam. Additionally, we conducted four sector-specific focus groups with a sub-sample of interview participants (k = 4, n = 22). Media and technology were brought up consistently in relation to sexual violence prevention and sexual health information. Key informants noted that, in Vietnam, generational differences in acceptability of sex and lack of comprehensive sexuality education intersect with new technological opportunities for exposure to sexual information and media. This creates a complex landscape that can promote sexual violence through priming processes, instigate mimicry of violent media, and presents new opportunities for the perpetration of sexual violence though technology. Development of comprehensive sexual education, including violence prevention education, is imperative, with consideration of age-specific needs for Vietnamese youth.

AbstractA 73-year-old male was admitted because of recurrent syncope. He was diagnosed with transient bradycardia caused by a 2:1 atrioventricular block, and he underwent cardiac computed tomography (CT) using 320 detector-row CT to screen for coronary artery disease. Significant coronary artery stenosis was not detected, but diffuse late iodinate enhancement was found on the epi-myocardium and endo-myocardium of the interventricular septum, and endo-myocardium of the anterior and lateral left ventricular (LV) myocardium (LVM) on CT. The ejection fraction and global longitudinal strain (LS) of LVM were 53.97% and − 9.87% on CT. Apical sparing was present, meaning the LS of LV apical segments were preserved compared with basal segments on CT. Pathological findings of LVM demonstrated loss of myocardial cells and extra-cellular amyloid deposition on the direct fast scarlet staining. He was finally diagnosed with transthyretin amyloidosis.
The Interplay of Cognitive Load, Learners’ Resources and Self-regulation
Authors: Seufert Tina , Hamm Verena , Vogt Andrea , Riemer Valentin 
Published: May 2024

AbstractSelf-regulated learning depends on task difficulty and on learners’ resources and cognitive load, as described by an inverted U-shaped relationship in Seufert’s (2018) model: for easy tasks, resources are high and load is low, so there is no need to regulate, whereas for difficult tasks, load is too high and resources are too low to regulate. Only at moderate task difficulty do learners regulate, as resources and load are in equilibrium. The purpose of this study is to validate this model, i.e., the inverted U-shaped relationship between task difficulty and self-regulatory activities, as well as learner resources and cognitive load as mediators. In the within-subject study, 67 participants reported their cognitive and metacognitive strategy use for four exams of varying difficulty. For each exam task difficulty, cognitive load, and available resources (such as prior knowledge, interest, etc.) were assessed. Multilevel analysis revealed an inverted U-shaped relationship between task difficulty and the use of cognitive strategies. For metacognitive strategies, only a linear relationship was found. Increasing cognitive load mediated these relationship patterns. For learner resources we found a competitive mediation, indicating that further mediators could be relevant. In future investigations a broader range of task difficulty should be examined.
Trans-to-cis isomerization of a platinum(II) complex with two triphosphine ligands via coordination with gold(I) ions

Published: May 2024

AbstractThe reaction of a square-planar platinum(II) complex containing two bis(2-diphenylphosphinoethyl)phenylphosphine (triphos), [Pt(triphos)2](NO3)2, with [Au(tu)2]Cl (tu = thiourea) gave a new trinuclear AuI2PtII complex, [Pt(triphos)2{Au(tu)}2]Cl2(NO3)2, through Au-P coordination. While the [Pt(triphos)2]2+ unit in [Pt(triphos)2](NO3)2 adopted the trans-meso configuration, only the cis-racemic isomer was observed for [Pt(triphos)2{Au(tu)}2]Cl2(NO3)2. 31P NMR spectroscopy indicated rapid equilibrium among the possible isomers of [Pt(triphos)2]2+, which facilitated the trans-to-cis transformation at the PtII center in this system. Additionally, we observed that this structural transformation led to an increase in the emission intensity.
On polling directions for randomized direct-search approaches: application to beam angle optimization in intensity-modulated proton therapy
Authors: Rocha H. , Dias J. 
Published: May 2024

Abstract
Deterministic direct-search methods have been successfully used to address real-world challenging optimization problems, including the beam angle optimization (BAO) problem in radiation therapy treatment planning. BAO is a highly non-convex optimization problem typically treated as the optimization of an expensive multi-modal black-box function which results in a computationally time consuming procedure. For the recently available modalities of radiation therapy with protons (instead of photons) further efficiency in terms of computational time is required despite the success of the different strategies developed to accelerate BAO approaches. Introducing randomization into otherwise deterministic direct-search approaches has been shown to lead to excellent computational performance, particularly when considering a reduced number (as low as two) of random poll directions at each iteration. In this study several randomized direct-search strategies are tested considering different sets of polling directions. Results obtained using a prostate and a head-and-neck cancer cases confirmed the high-quality results obtained by deterministic direct-search methods. Randomized strategies using a reduced number of polling directions showed difficulties for the higher dimensional search space (head-and-neck) and, despite the excellent mean results for the prostate cancer case, outliers were observed, a result that is often ignored in the literature. While, for general global optimization problems, mean results (or obtaining the global optimum once) might be enough for assessing the performance of the randomized method, in real-world problems one should not disregard the worst-case scenario and beware of the possibility of poor results since, many times, it is only possible to run the optimization problem once. This is even more important in healthcare applications where the mean patient does not exist and the best treatment possible must be assured for every patient.

Abstract
In Germany, a comprehensive reimbursement policy for extracorporeal membrane oxygenation (ECMO) results in the highest per capita use worldwide, although benefits remain controversial. Public ECMO data is unstructured and poorly accessible to healthcare professionals, researchers, and policymakers. In addition, there are no uniform policies for ECMO allocation which confronts medical personnel with ethical considerations during health crises such as respiratory virus outbreaks.Retrospective information on adult and pediatric ECMO support performed in German hospitals was extracted from publicly available reimbursement data and hospital quality reports and processed to create the web-based ECMO Dashboard built on Open-Source software. Patient-level and hospital-level data were merged resulting in a solid base for ECMO use analysis and ECMO demand forecasting with high spatial granularity at the level of 413 county and city districts in Germany.The ECMO Dashboard (https://www.ecmo-dash.de/), an innovative visual platform, presents the retrospective utilization patterns of ECMO support in Germany. It features interactive maps, comprehensive charts, and tables, providing insights at the hospital, district, and national levels. This tool also highlights the high prevalence of ECMO support in Germany and emphasizes districts with ECMO surplus – where patients from other regions are treated, or deficit – origins from which ECMO patients are transferred to other regions. The dashboard will evolve iteratively to provide stakeholders with vital information for informed and transparent resource allocation and decision-making.Accessible public routine data could support evidence-informed, forward-looking resource management policies, which are urgently needed to increase the quality and prepare the critical care infrastructure for future pandemics.
A Stepwise Cosimulation Framework for Modeling Critical Elements in Copper Porphyry Deposits
Authors: Nasretdinova Milena , Madani Nasser , Maleki Mohammad 
Published: May 2024

AbstractThe increased attention given to batteries has given rise to apprehensions regarding their availability; they have thus been categorized as essential commodities. Cobalt (Co), copper (Cu), lithium (Li), nickel (Ni), and molybdenum (Mo) are frequently selected as the primary metallic elements in lithium-ion batteries. The principal aim of this study was to develop a computational algorithm that integrates geostatistical methods and machine learning techniques to assess the resources of critical battery elements within a copper porphyry deposit. By employing a hierarchical/stepwise cosimulation methodology, the algorithm detailed in this research paper successfully represents both soft and hard boundaries in the simulation results. The methodology is evaluated using several global and local statistical studies. The findings indicate that the proposed algorithm outperforms the conventional approach in estimating these five elements, specifically when utilizing a stepwise estimation strategy known as cascade modeling. The proposed algorithm is also validated against true values by using a jackknife method, and it is shown that the method is precise and unbiased in the prediction of critical battery elements.
Pinning Group Consensus of Multi-agent Systems Under DoS Attacks
Authors: Lang Qian , Xu Jing , Zhang Huiwen , Wang Zhengxin 
Published: May 2024

AbstractIn this paper, group consensus is investigated for a class of nonlinear multi-agent systems suffered from the DoS attacks. Firstly, a first-order nonlinear multi-agent system is constructed, which is divided into M subsystems and each subsystem has an unique leader. Then a protocol is proposed and a Lyapunov function candidate is chosen. By means of the stability theory, a sufficient criterion, which involves the duration of DoS attacks, coupling strength and control gain, is obtained for achieving group consensus in first-order system. That is, the nodes in each subsystem can track the leader of that group. Furthermore, the result is extended to nonlinear second-order multi-agent systems and the controller is also improved to obtain sufficient conditions for group consensus. Additionally, the lower bounds of the coupling strength and average interval of DoS attacks can be determined from the obtained sufficient conditions. Finally, several numerical simulations are presented to explain the effectiveness of the proposed controllers and the derived theoretical results.
An unjustly neglected theory of semantic reference
Authors: Smit J. P. 
Published: May 2024

AbstractThere is a simple, intuitive theory of the semantic reference of proper names that has been unjustly neglected. This is the view that semantic reference is conventionalized speakers reference, i.e. the view that a name semantically refers to an object if, and only if, there exists a convention to use the name to speaker-refer to that object. The theory can be found in works dealing primarily with other issues (e.g. Stine in Philos Stud 33:319–337, 1977; Schiffer in Erkenntnis 13:171–206, 1978; Sainsbury in Erkenntnis 80:195–214, 2015; Sainsbury, Thinking about things, Oxford University Press, 2018), yet these authors provide no sustained discussion of it. Devitt (Designation, Columbia University Press, 1981) did formulate a view on which semantic reference is conventionalized speaker’s reference, yet his views are assimilated to causalist views. This is a mistake. While the conventionalized speaker’s reference view captures much of what is plausible in descriptivism and causalism, it remains distinct from both.
Safety’s coordination problems
Authors: Dutant Julien , Rosenkranz Sven 
Published: May 2024

AbstractThe safety conception of knowledge holds that a belief constitutes knowledge iff relevantly similar beliefs—its epistemic counterparts—are true. It promises an instructive account of why certain general principles of knowledge hold. We focus on two such principles that anyone should endorse: the closure principle that knowledge is downward closed under competent conjunction elimination, and the counter-closure principle that knowledge is upward closed under competent conjunction introduction. We argue that anyone endorsing the former must also endorse the latter on pains of an unacceptable form of bootstrapping. We devise new formal models to identify necessary and sufficient conditions for these principles to hold on conceptions that construe knowledge in terms of true counterparts. These conditions state that counterparts of premise and conclusion beliefs are coordinated in certain ways whenever these beliefs stand in the relevant inferential relations. We show that the safety conception faces insuperable problems vindicating these coordination principles, because its epistemic counterpart relation is symmetric. We conclude that it thus proves unable to account for minimal closure properties of knowledge. More generally, our formal results establish parameters within which any conception must operate that construes knowledge in terms of true counterparts.
States’ culpability through time
Authors: Collins Stephanie 
Published: May 2024

AbstractSome contemporary states are morally culpable for historically distant wrongs. But which states for which wrongs? The answer is not obvious, due to secessions, unions, and the formation of new states in the time since the wrongs occurred. This paper develops a framework for answering the question. The argument begins by outlining a picture of states’ agency on which states’ culpability is distinct from the culpability of states’ members. It then outlines, and rejects, a plausible-seeming answer to our question: that culpability transmits from a past state’s action to a present state just if the two states share a numerical identity, for example as determined by international law. I advocate a different answer: culpability transmits from a past action to a present state to the extent that the present state ‘descends from’ the aspects of the past state that underpinned the past action. One potential upshot is that some present-day settler-colonies (such as Australia) are culpable for the centuries-ago invasion of their lands by European powers—even though these states did not perform these invasions and indeed did not exist at the time.
