Forward ion acceleration by laser-driven collisionless filamentary shocks in underdense plasmas
Authors: Kordell P. , Russell B. K. , Campbell P. T. , Krushelnick K. , Maksimchuk A. , Willingale L.
Published: November 2024

We have experimentally investigated the collisionless shock acceleration of ions via the interaction of a relativistic intensity (3 × 1019 W/cm2), 1.053 µm wavelength laser pulse with an underdense plasma. This plasma is formed through the use of a novel cluster jet design that allows for control of the plasma peak density and front scale length without the use of additional plasma-forming laser pulses. When the front density scale length of the target plasma is less than 60 µm, the laser pulse (1 J, 400 fs) is capable of launching an electrostatic shock wave that accelerates a proton beam. This beam is shown to have a narrow divergence angle of 0.8°, a peak flux of 14 × 106 protons/sr with an ion energy exceeding 440 keV. Particle-in-cell simulations indicate this narrow ion beam is produced by converging shocks generated via filamentation of the laser pulse in high-density (near critical) plasma.
A criterion to detect a non-trivial homology of an invariant set of a flow in $\mathbb{R}^3$
Authors: Sánchez-Gabites J. J.
Published: November 2024

Consider a flow in

$\mathbb{R}^3$

and let K be the biggest invariant subset of some compact region of interest

$N \subseteq \mathbb{R}^3$

. The set K is often not computable, but the way the flow crosses the boundary of N can provide indirect information about it. For example, classical tools such as Ważewski’s principle or the Poincaré–Hopf theorem can be used to detect whether K is non-empty or contains rest points, respectively. We present a criterion that can establish whether K has a non-trivial homology by looking at the subset of the boundary of N along which the flow is tangent to N. We prove that the criterion is as sharp as possible with the information it uses as an input. We also show that it is algorithmically checkable.

Published: November 2024

Based on a new cored succession at Winterswijk, evidence is uncovered of the end-Triassic mass-extinction (ETME) event in a subsurface sedimentary succession of the Netherlands. The ETME was one of the most devastating events for the biosphere during the Phanerozoic era. Massive volcanism from the Central Atlantic Magmatic Province initiated the breakup of the supercontinent Pangea and resulted in terrestrial and marine extinction pulses, which drastically altered the course of life on Earth. The newly cored material reveals a sedimentary succession representing a shallow marine setting dominated by laminated black shale and claystone deposits. A high-resolution palynostratigraphic dataset provides evidence for a late Rhaetian vegetation assemblage that displays a stepwise decline of arborescent tree vegetation that is transiently replaced by a community of ferns and fern allies. Geochemical records link this major disturbance in palynofloral biodiversity to a pulse of volcanic activity as evidenced by a negative excursion in stable organic carbon isotopes. Shifts towards drier climate conditions, as inferred from sedimentary elemental composition, suggest continental aridification strongly influenced the terrestrial realm following volcanic pulses. Presence of reworked material suggests unstable soils that were affected by increased erosion rates, inhibiting the re-establishment of conifer tree vegetation. Comparison of our findings with other contemporaneous European Triassic-Jurassic boundary sections confirms the progression of the end-Triassic extinction, which exhibits a two-phased structure. The presence of the ETME in the subsurface of the Netherlands provides further evidence towards our understanding of terrestrial extinction with emphasis on the decline of vegetation.
A MELTING SNOWBALL—DIFFICULTIES IDENTIFYING PARTICULAR CUSTOMARY INTERNATIONAL LAW
Authors: Gutiérrez Álvarez José Rogelio
Published: November 2024

This article discusses the relationship between particular and general customary international law, grappling with academic views affirming that, ordinarily, the emergence of the former is a stage in the consolidation of the latter. It is argued that the higher standard of State consent required for the configuration of bilateral or regional custom suggests otherwise. In addition, it is also contended that a distinctive kind of opinio juris must be present for particular custom to arise: a conviction from the States concerned that their conduct is governed by particular (as opposed to general) customary law.
The privation theory of evil and the evil-God challenge
Authors: Collins John M.
Published: November 2024

Can the best arguments for a privation theory of evil be parodied, with equal plausibility, as arguments for a privation theory of good? The privation theory of evil claims that evil has no positive existence, and it is but a privation of good. The privation theory of good claims the opposite. I approach this topic as one element in the so-called evil-God Challenge. Stephen Law has argued that the epistemic support for belief in an omniscient, omnipotent, and morally perfect God (theism) is on a par with the epistemic support for belief in an omniscient, omnipotent, but completely evil-God (maltheism). In fact, he concludes, the arguments for an evil God are symmetrical with, and isomorphic to, those for a good God. The privation theory of evil has often been used to defend theism against the argument from evil. Thus, part of the evil-God Challenge is to evaluate arguments for the privation theory of evil for their vulnerability to maltheist parody. I consider a broad range of arguments for the privation theory of evil, and I argue that most of them are vulnerable to parodic neutralization. Furthermore, I argue that although the thesis of the convertibility of being and goodness is often held to entail the privation theory of evil, or to be entailed by it (or to be equivalent to it), it is independent of the privation theory. I do find that David Oderberg’s recent argument for the privation theory of evil resists any easy maltheist parody, but I argue that it has a defect. I sketch an argument according to which his good-as-fulfillment account is compatible with a perfectly evil god. My tentative conclusion is that the privation theory of evil enjoys little more plausibility than does the privation theory of good.
‘Block’ing evil’s defeat
Authors: Page Ben
Published: November 2024

There is this view propounded by some theorists which claims that some conceptions of the nature of time are incompatible with the Christian position on the defeat of evil. The aim of this article is twofold. First, to clarify exactly which thesis about time’s nature is taken to be problematic for the defeat of evil. And second, to show that scriptural support for understanding the defeat of evil as requiring that evil not be in the range of the existential quantifier, something implicitly contended by those who put forward this problem, is weak and that these passages can be read in plausible ways which are affirmable by those who endorse the ‘problematic’ thesis.
Scientific models versus power politics: How security expertise reframes solar geoengineering
Authors: Corry Olaf , McLaren Duncan , Kornbech Nikolaj
Published: November 2024

Persistently rising atmospheric greenhouse gas concentrations challenge dominant Liberal hopes that science and multilateralism might deliver rational, global climate outcomes. Emerging Realist climate approaches that take geopolitics and national interests more seriously have yet to explore Morgenthau’s concern that ‘scientism’ – exaggerated faith in scientific rationality to solve political problems – would lead to disastrous underestimations of power and irrationality. Recently, Realists have mooted ‘solar geoengineering’ designs as a ‘lesser evil’ option to deliberately cool the Earth independently of emissions reductions. However, assessments of solar geoengineering prospects barely factor in Realist concerns, focusing instead on idealised scientific modelling of bio-physical effects and Liberal governance scenarios. To explore how geoengineering techno-science would be ‘translated’ into security assessments, geopolitical logics were elicited through interviews and group discussions with (mainly Arctic-oriented) national security professionals. Security experts reframe solar geoengineering in three significant ways: (a) from a climate ‘global public good’ to a source of geopolitical leverage and disruption; (b) from a risk-reduction tool to a potential source of distrust and escalation; and (c) from a knowledge-deficit problem solvable by more research, to a potential disinformation vector. This expands Realist scholarship on climate change and identifies serious risks to ongoing scientific and commercial pursuit of such technologies.
Order as Resilience-Governance of Sameness and Diversity
Authors: Flockhart Trine
Published: November 2024

One of the problems with the problem of world order is that what makes for order within societies is often precisely what makes for disorderly relations between them. I argue in this short essay that many of the problems with the problem of world order arise from assumptions that are widely shared within a discipline where the language of power and interest dominates and where a view of states as “like units” permeates. With more emphasis on values and visions of the good life, and acceptance that the ontological foundation of IR is difference rather than sameness, the debates about the problem of world order would take on a different form. The essay adapts the work of Hedley Bull and introduces the concept of “resilience-governance” to distinguish between resilience as a practice of self-governance taking place within ordering domains and resilience as a practice of “diversity-governance” taking place between ordering domains. The combination of the two allows for a bifocal view into how practices of resilience as self-governance may produce order within individual domains but will at the same time increase diversity and difference between the ordering domains, hence making the practices of resilience as diversity-governance much more challenging.
The International Order of White Sovereignty and the Prospect of Abolition
Authors: Brown Owen R.
Published: November 2024

Discussions of the liberal international order, both inside and outside the academy, tend to take its necessity and desirability for granted. While its specific contours and content are left somewhat open in such debates, the idea that this international order is essential for global peace and stability is left largely unquestioned. What is more, the potential loss or end of this order is often taken to mean a return to anarchy, chaos, and disorder. In this essay, I question the presumed necessity and desirability of the liberal international order that most discussions of it seem to share. By rethinking the international order as processual, emergent, and grounded in the social and political contexts that shape its constitution and operation, I suggest that fears about the crisis of international order are less about international order itself and more about the loss of a specific order. This specific order, I argue, constituted in part through processes of racialization, is not so much a rules-based order of sovereign equality but rather an international order of White sovereignty that secures the domination and rule of some over others, of Whiteness over non-Whiteness. Recognizing the role of White sovereignty in the contemporary international order points toward a need to take seriously calls for abolition. Rather than signifying a return to chaos and disorder, the prospect and promise of abolition represents a call to break free from the constraints of the present order and reach into an as-yet-unimaginable future.
The Politics of Pedagogy: The Problem of Order in the IR Classroom
Authors: Mitzen Jennifer
Published: November 2024

The Hobbesian problem of order has been central to international relations (IR) pedagogy. What are the political implications of this pedagogy? Giving students conceptual tools to understand world politics feels vital in this moment of anxiety about the erosion of the current international order. But some of the deepest threats to international order are rooted in a multiplicity of justice claims. IR's explanatory orientation, and the many biases underlying its anchoring concepts, limit our ability as educators to make sense of those threats in the language of the discipline. How do we teach IR, then, without socializing students into a problematic discipline that only reproduces the existing order? I propose that rather than jettison our disciplinary concepts and frames with their baked-in injustices, we can reorient our teaching about them. Drawing on history and mythology, I focus on the Westphalian myth that anchors IR's central question: Given states, how can international order be produced? I suggest another version of the myth that foregrounds how order and justice, the explanatory and the normative, are entangled all the way down. This revised Westphalian myth urges us to think of recognition of political units—a justice claim—as intrinsic to ordering decisions.
The Origins of Policy Ideas in German Pension Debates
Authors: Röper Nils
Published: November 2024

Understanding the origins of policy ideas can be crucial when trying to explain dynamics of political change and continuity. Paradigmatic changes in the German pension system have been attributed to the import of “foreign” neoliberal policy ideas from transnational organizations and other countries. The literature describes such processes as policy diffusion, transfer, or translation. In contrast, this article argues that foreign pension ideas did not have a substantive influence on local policy innovations and preference-formation processes. Instead, pension policy pioneers developed their ideas predominantly “from within” through bricolage by reconfiguring long-standing domestic schools of thought. Drawing on a wide range of primary and secondary sources, the analysis combines a broad historical perspective with case studies of individual policy makers. This sheds new light on the careers of ideas and why significant actors pick them up at certain points.
Cross-Domain Policy Feedback: The Institutionalization of Collective Bargaining Rights for Health Care Workers
Authors: Brown Trevor E.
Published: November 2024

This article considers a significant but overlooked set of policy developments in the latter half of the twentieth century: the extension of collective bargaining rights to most health care workers, many of whom were formally excluded for three decades under the 1947 Taft-Hartley amendments. Drawing on primary sources including archival records, an exhaustive review of congressional testimony, and rulings from the quasijudicial agency governing private sector industrial relations, this article shows that health care workers did so in two interrelated processes. First, in coordination with the civil rights movement, workers mobilized and used both disruptive and legal social movement tactics. Second, in doing so they drew the state into and revealed its position in the collective bargaining process between workers and health institutions, facilitating what is conceptualized as cross-domain policy feedback. Cross-domain policy feedback occurs when a policy in one domain (e.g., public health spending) influences the politics of a policy in a seemingly separate one (e.g., labor and employment relations). Such effects, this article suggests, are likely to occur when a policy is relatively large in scale, implicates actors with a diverse set of interests, and offers significant ambiguity and discretion in its implementation. Empirically, this article is the first to chart the institutionalization of collective bargaining rights for health care workers, among the largest group of private sector employees in the postindustrial economy. It also offers a new theoretical and conceptual framework through which to study the ways by which public policies reshape political dynamics—an enduring research agenda for students of American politics and policy.
Inflation and the Corruption of Currency in Latin America: Chile, 1970–1973
Authors: Edwards Sebastian
Published: November 2024

In this article I analyze Salvador Allende’s economic program and policies. I argue that the explosion of inflation during his administration (above 1,500% on a six-month annualized measure) was predictable, and I show that the government’s response to it was political. I postulate that runaway inflation generated major disaffection among the middle class and that that unhappiness paved the way to Pinochet’s coup d’état in 1973.
A self-driven ESN-DSS approach for effective COVID-19 time series prediction and modelling
Authors: Wang Weiye , Li Qing , Wang Junsong
Published: November 2024

Since the outbreak of the COVID-19 epidemic, it has posed a great crisis to the health and economy of the world. The objective is to provide a simple deep-learning approach for predicting, modelling, and evaluating the time evolutions of the COVID-19 epidemic. The Dove Swarm Search (DSS) algorithm is integrated with the echo state network (ESN) to optimize the weight. The ESN-DSS model is constructed to predict the evolution of the COVID-19 time series. Specifically, the self-driven ESN-DSS is created to form a closed feedback loop by replacing the input with the output. The prediction results, which involve COVID-19 temporal evolutions of multiple countries worldwide, indicate the excellent prediction performances of our model compared with several artificial intelligence prediction methods from the literature (e.g., recurrent neural network, long short-term memory, gated recurrent units, variational auto encoder) at the same time scale. Moreover, the model parameters of the self-driven ESN-DSS are determined which acts as a significant impact on the prediction performance. As a result, the network parameters are adjusted to improve the prediction accuracy. The prediction results can be used as proposals to help governments and medical institutions formulate pertinent precautionary measures to prevent further spread. In addition, this study is not only limited to COVID-19 time series forecasting but also applicable to other nonlinear time series prediction problems.
Elementary quantum recursion schemes that capture quantum polylogarithmic-time computability of quantum functions
Authors: Yamakami Tomoyuki
Published: November 2024

Quantum computing has been studied over the past four decades based on two computational models of quantum circuits and quantum Turing machines. To capture quantum polynomial-time computability, a new recursion-theoretic approach was taken lately by Yamakami [J. Symb. Logic 80, pp. 1546–1587, 2020] by way of recursion schematic definition, which constitutes six initial quantum functions and three construction schemes of composition, branching, and multi-qubit quantum recursion. By taking a similar approach, we look into quantum polylogarithmic-time computability and further explore the expressing power of elementary schemes designed for such quantum computation. In particular, we introduce an elementary form of the quantum recursion, called the fast quantum recursion, and formulate $EQS$ (elementary quantum schemes) of “elementary” quantum functions. This class $EQS$ captures exactly quantum polylogarithmic-time computability, which forms the complexity class BQPOLYLOGTIME. We also demonstrate the separation of BQPOLYLOGTIME from NLOGTIME and PPOLYLOGTIME. As a natural extension of $EQS$, we further consider an algorithmic procedural scheme that implements the well-known divide-and-conquer strategy. This divide-and-conquer scheme helps compute the parity function, but the scheme cannot be realized within our system $EQS$.
New observations on the quilisma: occurrence, position and function in northern Low Countries sources
Authors: Tienstra Rens
Published: November 2024

The quilisma is a sign found in the earliest surviving notations of Gregorian chant. Since the ‘chant restoration’ of the nineteenth and twentieth centuries, the sign is included once again in all chant books, and poses an inevitable question of interpretation to those studying and performing chant. However, since medieval times, there has been considerable debate whether the sign denotes a particular method of voice production, a particular rhythmic value and/or an element in a melody's modal orientation. Chant manuscripts of the northern Low Countries (the northern half of the modern-day Netherlands), although not well known for their melodic content, point to highly interesting developments in response to a continually changing musical aesthetic. Likewise, these manuscripts offer new insights into the quality of the quilisma: the sign was widely used in the region up to the sixteenth-century Dutch Revolt, and for much longer than in the better-known square notation. Through analytical and comparative study, the sign's occurrence, position, development, relation to other signs and functions are clarified and presented in this article along with insights into its unique notational development.
The insular daily Lady Mass of the thirteenth century: sources, repertory and transmission
Authors: Steiner Katherine Kennedy
Published: November 2024

A new daily ritual, commonly called the Salve Mass or Lady Mass, rapidly grew throughout the British Isles in the High Middle Ages inspiring new festive chants. John Harper's introduction to Mass of the Blessed Virgin Mary establishes the sources of the Lady Mass in its fully developed form in the late Use of Salisbury and earlier related sources. Yet the Marian Mass collections in insular graduals, missals and non-liturgical sources identified in this article exhibit significant local adaptations not assigned in Salisbury Ordinals. I argue that extant Marian Kyries, alleluias and offertories contained in thirteenth-century insular liturgical sources of the Mass of the Virgin Mary are evidence of the daily Lady Mass. A study of chant variants and sources demonstrates the insular circulation of some of these chants outside of sources replicating the Lady Mass at Salisbury. The insular repertory of Marian Mass music, examined here for the first time with concordances in fragmentary and non-liturgical collections, reveals a lively exchange of repertory and compositional techniques between insular monastic and secular churches. This regionally developed, decentralised ritual had an important impact on music composition and transmission in the British Isles in the thirteenth century.
Investigating reformulation in the Canadian food supply between 2017 and 2020 and its impact on food prices
Authors: Ziraldo Emily R , Hu Guanlan , Khan Ayesha , L’Abbé Mary R
Published: November 2024

Objective:

This study examined the relationship between reformulation and food price in Canadian packaged foods and beverages between 2017 and 2020.

Design:

Matched foods and beverages in the University of Toronto Food Label Information and Price 2017 and 2020 databases were analysed (n 5774). Price change by food category and by retailer were compared using Wilcoxon signed-rank tests. The proportion of products with changes in calories and nutrient levels were determined, and mixed-effects models were used to examine the relationship between reformulation and price changes. The Food Standards Australia New Zealand (FSANZ) nutrient profiling model was applied to calculate nutritional quality scores, and mixed-effects models were used to assess if changes in nutritional quality score were associated with price changes.

Setting:

Large grocery retailers by market share in Canada.

Participants:

Foods and beverages available in 2017 and 2020.

Results:

Food price changes differed by retailer and by food category (e.g. increased in Bakery, Snacks, etc; decreased in Beverages, Miscellaneous, etc.). Nutrient reformulation was minimal and bidirectional with the highest proportion of products changing in sodium (17·8 %; 8·4 % increased and 9·4 % decreased). The relationship between nutrient reformulation and price change was insignificant for all nutrients overall and was not consistent across food categories. Average FSANZ score did not change (7·5 in both years). For Legumes and Combination dishes, improvements in nutritional quality were associated with a price decrease and increase, respectively.

Conclusions:

Stronger policies are required to incentivise reformulation in Canada. Results do not provide evidence of reformulation impacting food prices.
An interpretative qualitative case study of a Compassionate Cities initiative in the United Kingdom: Lessons for implementation in other settings
Authors: Nawaratne Sashiprabha Dulanjalee , Dale Jeremy , Mitchell Sarah , MacArtney John I.
Published: November 2024

Objectives

Compassionate Cities are a novel approach to health-promotive palliative care that uses a population-based approach to promote health and encourage its citizens to act with confidence to help others during death, dying, or bereavement. This study aimed to provide a critical account of how the leaders of a Compassionate City adopted the initiative and how they experienced its development and implementation.

Methods

An interpretative qualitative case study was conducted in a newly established Compassionate City in the UK. Data was collected using in-depth interviews, documentary analysis, and non-participatory observations. Reflective thematic analysis was used to analyze the contents of the multiple resources.

Results

Five observations, 4 document analyses, and 11 interviews with members of the Compassionate City steering committee were conducted. We identified 4 themes: right model, right people, in the right place, at the right time; building a network of organizations and individuals; building sustainable community capacity to deal with grief, loss, and bereavement; and, embedding and sustaining the Compassionate City initiative. The study also found that cross-cutting factors such as leadership, visibility of work, evaluation, communication, and funding influenced and shaped the key themes when developing and implementing the Compassionate City.

Significance of results

This study provides broad insight into the key actions taken by the leaders of a Compassionate City aiming to improve the end-of-life experience of its citizens. We highlight the many challenges and complexities faced by the leaders when translating the concepts of Compassionate Cities into practice and identify key elements to consider for the successful implementation of future initiatives.
Timed array architectures and integrated true-time delay elements for wideband millimeter-wave antenna arrays
Authors: Koch Manuel , Schönhärl Stefan , Breun Sascha , Fischer Georg , Weigel Robert
Published: November 2024

Antenna arrays are a main driver of next generation millimeter-wave communication and radar systems as shrinking antenna sizes leverage larger arrays to compensate for reduced link budget. However, conventional phase controlled arrays exhibit a frequency dependent scan angle that appears as loss to a fixed counterpart. Bandwidth limitations introduced by the so-called beam squint effect hinder larger array sizes and data rates thereby generating a demand for timed arrays as a solution. This paper gives a quantified overview of the beam squint phenomenon, different hardware architectures as well as evaluation parameters and common shortcomings of true-time delay (TTD) elements. A broad variety of TTD realizations from literature are compared by their operational principles and performance. Finally, the delay interpolation principle, its non-idealities, and their impact on a hierarchically time delay controlled D-band antenna array are described. Extended content on a previously published, continuously tunable TTD implementation at a center frequency of 144 GHz with a bandwidth of 26 GHz and a delay range of 1.75 ps that requires only 0.53 × 0.3 mm2 of core chip area is presented. Measurement results have been obtained from a demonstrator manufactured in 130 nm BiCMOS technology.
Human-in-the-loop optimization of wearable device parameters using an EMG-based objective function
Authors: Díaz María Alejandra , De Bock Sander , Beckerle Philipp , Babič Jan , Verstraten Tom , De Pauw Kevin
Published: November 2024

Advancements in wearable robots aim to improve user motion, motor control, and overall experience by minimizing energetic cost (EC). However, EC is challenging to measure and it is typically indirectly estimated through respiratory gas analysis. This study introduces a novel EMG-based objective function that captures individuals’ natural energetic expenditure during walking. The objective function combines information from electromyography (EMG) variables such as intensity and muscle synergies. First, we demonstrate the similarity of the proposed objective function, calculated offline, to the EC during walking. Second, we minimize and validate the EMG-based objective function using an online Bayesian optimization algorithm. The walking step frequency is chosen as the parameter to optimize in both offline and online approaches in order to simplify experiments and facilitate comparisons with related research. Compared to existing studies that use EC as the objective function, results demonstrated that the optimization of the presented objective function reduced the number of iterations and, when compared with gradient descent optimization strategies, also reduced convergence time. Moreover, the algorithm effectively converges toward an optimal step frequency near the user’s preferred frequency, positively influencing EC reduction. The good correlation between the estimated objective function and measured EC highlights its consistency and reliability. Thus, the proposed objective function could potentially optimize lower limb exoskeleton assistance and improve user performance and human–robot interaction without the need for challenging respiratory gas measurements.

Redox Sensitive Mineral Magnetic Signatures of Seafloor Massive Sulfide Deposits
Authors: Wang Shishun , Tao Chunhui , Liao Shili , Cai Mingcheng , Wu Tao , Wang Mingxu
Published: November 2024

Seafloor massive sulfide (SMS) deposits in different geological settings can have variable magnetic mineralogy, but the mechanism and implications of their spatiotemporal diversity are poorly understood. Based on seabed shallow drilling and surficial sampling of the Yuhuang hydrothermal field, Southwest Indian Ridge, we investigate here whether ubiquitous oxidative weathering affects the magnetic properties of SMS deposits. Microscopic observation and ferrous iron concentrations reveal that seafloor SMS deposits are extensively oxidized; subseafloor SMS deposits are relatively fresh, but oxidation initiates immediately after sample recovery. Negative frequency dependence of magnetic susceptibility likely due to measurement eddy currents is observed for fresh samples but not for oxidized ones, which suggests that oxidative weathering reduces the electromagnetic detectability of SMS deposits in geophysical investigations. Pyrrhotite (and probably other magnetic iron sulfide minerals), magnetite, and hematite are recognized as dominating magnetic (ferromagnetic, sensu lato) minerals in SMS deposits. Electron and quantum diamond microscope observations reveal pyrrhotite mineralization from high‐temperature reducing hydrothermal fluids, while iron‐oxides are mostly oxidation products of primary sulfides. Oxidative weathering modifies paleomagnetic records of SMS deposits. Bulk magnetic parameters vary systematically with enhanced oxidation degree. Temperature‐dependent magnetic measurements are useful tools for distinguishing the oxidation state of SMS deposits. Overall, these findings explain magnetic mineral variability in SMS deposits, linking mineral magnetic properties with seafloor geophysical investigations. Mineral magnetism can also be a redox state proxy for tracing natural and artificial environmental fluctuations in seafloor hydrothermal fields, inspiring novel interdisciplinary research to understand interactions in the dynamic Earth System.
Dependencies of Simulated Convective Cell and System Growth Biases on Atmospheric Instability and Model Resolution

Published: November 2024

This study evaluates convective cell properties and their relationships with convective and stratiform rainfall within a season‐long convection‐permitting weather research and forecasting simulation over central Argentina using radar, satellite, and radiosonde measurements from the RELAMPAGO‐CACTI field campaign. The simulation slightly underestimates radar‐estimated rainfall over the ∼3.5‐month evaluation period but underestimates stratiform rainfall by 46% and overestimates convective rainfall by 43%. As convective available potential energy (CAPE) increases, the convective rainfall overestimation decreases, but the stratiform rainfall underestimation increases such that the contribution of convective to total rainfall remains constantly high biased by ∼26%. Overestimated convective rainfall arises from the simulation generating 2.6 times more precipitating convective cells (14,299) than observed by radar (5,662) despite similar observed and simulated cell growth processes, with relatively wide cells contributing mostly to excessive convective rainfall. Relatively shallow cells, typically reaching heights of 4–7 km, contribute most to the cell number bias. This cell number bias increases as CAPE decreases, potentially because cells and their updrafts become narrower and more under‐resolved as CAPE decreases. The gross overproduction of precipitating shallow cells leads to overly efficient precipitation and inadequate detrainment of ice aloft, thereby diminishing the formation of robust stratiform rainfall regions. Decreasing model horizontal grid spacing from 3 to 1 or 0.333 km for low (<300 J kg−1) and high CAPE (>1,000 J kg−1) cases results in minimal change to cell number, depth, and convective‐to‐stratiform partitioning biases. This suggests that improving prediction of these convective properties depends on factors beyond solely increasing model resolution.

Published: November 2024

Clarifying the controlling factors of annual variations in evapotranspiration (ET) and its components (transpiration (T) and evaporation (E)) over alpine grasslands of high‐cold regions is vital to understanding the hydrological processes of the terrestrial ecosystem. Therefore, this study investigated the variability of ET and its components over the alpine grasslands of the Tibetan Plateau (TP) and the driving factors underlying these changes during 1961–2013. The results showed that the annual ET over alpine grasslands was 339 mm, of which 59% and 41% were contributed by E and T, respectively. Annual ET, E, and T over the TP grasslands changed insignificantly before 1995, whereas increased dramatically during 1995–2013. Regarding different alpine grassland types, annual ET and its components in seasonal frost regions (SAG) were larger than in permafrost regions (PAG). The increase of ET and its components in PAG was profoundly larger than that in the SAG region during 1995–2013. Water and energy factors controlled the ET of approximately 65% and 31% area of the TP grasslands, respectively. Leaf area index was the major cause of T variability throughout 64% area of TP grasslands, while regions where energy factors were the major force of T change were mainly located in the eastern SAG region. Variability of E on entire TP grasslands (81%) was mainly regulated by available water supply. Our results indicate that as permafrost degradation has the potential to amplify climate warming and precipitation increase, ET over the PAG region was expected to continue increasing faster than the SAG region.

Forest status is crucial for catchment hydrology and water quality but is increasingly disturbed by human activities and climatic factors. Therefore, it is urgently necessary to develop water quality models that can adapt to these changes. This study used a new dynamic Hydrological Predictions for the Environment (HYPE) model to assess the effect of rapid and continuous forest changes on catchment hydrology and nitrogen export. The modified HYPE model was implemented for the 25 years period in the Große Ohe catchment in Germany, which has experienced severe forest dieback and recovery. Due to the stochastic nature of infestation events, data covering the entire process of forest change are rare. The modified HYPE model performed well at different scales for discharge and dissolved inorganic nitrogen (DIN) export. It was able to (a) capture the timing of peak flows and the seasonal DIN concentration dynamics and (b) reflect the initial increase and subsequent decrease trend in discharge and DIN export in accordance with forest dieback and regeneration. The increase in nitrogen export after forest dieback primarily resulted from reduced forest uptake and increased soil nitrogen availability from tree residues. The difference in runoff and nitrogen export increment with or without regeneration highlights the importance of forest regeneration in restoring catchment hydrology and water quality. Additionally, a decrease in DIN export after residue removal implies the impact of sound post‐disturbance management strategies. The dynamic modeling under changing catchment forests can enhance the analysis of catchment water quality and effectively support forest management.

Published: November 2024

Background

Less invasive surfactant administration (LISA) is associated with better outcomes than InSurE (Intubation-Surfactant administration-Extubation). Video-laryngoscopy (VL) facilitates intubation in neonates, however safety and cost-effectiveness of VL-assisted LISA have not been evaluated.

Methods

We compared the outcomes of infants receiving VL-assisted LISA (n = 67) with a historical cohort of infants who received InSurE (n = 52). Secondary aims were to evaluate safety and cost-effectiveness.

Results

VL-assisted LISA was associated with reduced duration of non-invasive ventilation (NIV), reduced duration of oxygen therapy, reduced composite days on NIV and mechanical ventilation (MV), and shorter NICU stay with lower hospital costs for infants ≥29 weeks GA, compared to InSurE. In the VL-assisted LISA group, 66% of the tracheal catheters were placed on the first attempt and 16% of infants displayed desaturation during placement.

Conclusion

In infants ≥29 weeks GA, VL-assisted LISA reduced exposure to NIV, oxygen, NIV and MV combined, length of stay, and cost of care compared to InSurE.

This article presents a Z source (ZS) based switched capacitor multilevel inverter (SC-MLI) with low capacitors charging inrush currents utilizing a modified modulation strategy. The topology generates nine output voltage levels with quadruple voltage gain utilizing eight power switches, five capacitors, two inductors, four discrete diodes, and a single DC source. The voltage gain can be further increased by applying shoot through (ST) states to the frontend ZS-network. Owing to its high voltage gain, the topology is suitable for low voltage renewable energy sources such as photovoltaics (PV), and fuel cells (FC). A modified modulation strategy is presented based on the conventional level shifted sinusoidal pulse width modulation (LS-SPWM). The proposed modulation strategy improves the dc-link utilization at higher modulation index. A detailed mathematical analysis is provided for the gain calculation based on the modified modulation strategy. A comparative study is implemented to verify the merits of the proposed topology. A simulation model is implemented utilizing MATLAB / Simulink to verify the topology characteristics. The power losses and efficiency calculations are presented using Altair PSIM. Furthermore, an experimental prototype is constructed to verify the simulation findings. The topology is tested with different loading conditions at numerous modulation index values and ST duty ratios. Furthermore, step change conditions are implemented to test the topology response. The effect of the ZS network on the switched capacitors charging inrush currents is validated. The proposed topology shows an overall advantage in terms of the output characteristics as well as the hardware requirements.
Estimating the impact of airport wildlife hazards management on realized wildlife strike risk

Published: November 2024

Collisions between wildlife and aircraft, commonly referred to as wildlife strikes or bird strikes, are rare events that pose considerable safety and economic risks to the aviation industry. Given the potentially dramatic consequences of such events, airports scheduled for passenger service are required to conduct wildlife hazard assessments and implement wildlife hazard management plans for the purpose of mitigating wildlife strike risk. The evaluation of such management, however, is complicated by imperfect reporting that mediates the relationship between realized wildlife strike risk and wildlife strike metrics. In this paper, we shed light on such phenomena by investigating the staggered adoption of a federal wildlife hazards management program at joint-use airports across the contiguous United States. This research design allowed us to exploit variation in both management presence across airports, over time as well as variation in the quality of wildlife strike reporting within airports. As hypothesized, we found that wildlife hazards management intervention has a significant impact on the quality of reporting, as evidenced by a substantial increase in the number of civil strikes reported over the management period. Where pre-existing reporting mechanisms were more robust, however, we found that wildlife hazards management had a significant impact on realized wildlife strike risk as evidenced by a decrease in strike-induced economic damages among military aircraft. Overall, we found that the estimated economic benefits of the studied airport wildlife hazards management program were 7 times greater than the costs over the management period. Our results have important implications for the measurement of wildlife strike risk and the management of wildlife hazards at airports, as well as important insights pertaining to the use of observational data for causal inference, particularly in the context of risk management.
