Era of uncertain events: Swedish foreign trade in 2010–2023
Authors: Hilmola Olli-Pekka , Fjellström Daniella , Hilletofth Per
Published: November 2024

International trade has experienced since Global Financial Crisis (GFC) numerous uncertainties and risks. There are some countries that have successfully navigated in this challenging environment, like Sweden. In this research, we analyze the changes in trade between 2010–2023. For imports, the role of Russia, United Kingdom (UK) and Denmark has declined, while the importance of the Netherlands, Norway, and Poland show increase. For exports, a diminishing role of UK and Russia could be detected, while the role of the USA, Poland, Germany and China has increased. Our interpretation is that these trade changes are due to global geopolitical, i.e. macro-level shifts. Both Brexit (2016 onwards) and Russian invasion of Ukraine (2014 onwards) show long-term trade effects. Prior both UK and Russia held high importance; however, in the recent years, especially exports to USA have played more important role, and it is providing growth and surplus. Despite the export growth to Poland, Germany, and China, the trade to these countries remains to show trade deficit. We also analyze the impact of trade changes on maritime trade. Although, the overall handling at sea ports has declined, but container based trade demonstrates clear growth. Direct container connections to UK and Russia have declined substantially in the observation period as Chinese show significant increase.
Intelligent sliding mode fault-tolerant control for aircraft engines with actuator dynamics and faults based on adaptive dynamic programming
Authors: Xiao L.F. , Tan Y.S. , Du Y.B , Zhang X.L
Published: November 2024

The fault-tolerant control issue of aircraft engines with actuator dynamics and faults is investigated in this paper. By proposing a novel intelligent sliding mode fault-tolerant control (ISMFTC) method, which combines an adaptive dynamic programming (ADP) sliding surface with Grey Wolf Optimizer (GWO) for controller parameter optimisation, the goal is to achieve quality steady-state and dynamic performance in aircraft engines while maintaining strong fault-tolerance properties. Firstly, by considering not only actuator dynamics but also actuator faults, an uncertain nonlinear cascaded model of aircraft engines is developed according to characteristic of aircraft engines and their actuators. Secondly, an ADP-based sliding surface is proposed for considered aircraft engine uncertain nonlinear cascaded system. It can obtain a certain sense of optimised performance, and could be solved by ADP strategy off-line as well. Thirdly, fault-tolerant controller is obtained on the basis of sliding mode theory and adaptive fault estimation law, namely, ADP-based ISMFTC controller. Meanwhile, GWO is integrated into the investigation of ADP-based ISMFTC controller, optimised designable control parameters are obtained subsequently. Besides, robustness analysis is elaborated according to Lyapunov theory, fault estimation error is bounded and states of closed-loop system are uniformly ultimately bounded. Simulation on a twin-shaft turbofan aircraft engine, indicates the effect of proposed ADP-based ISMFTC method.
Exact planetary waves and jet streams
Authors: Pizzo Nick , Salmon Rick
Published: November 2024

We investigate exact nonlinear waves on surfaces locally approximating the rotating sphere for two-dimensional inviscid incompressible flow. Our first system corresponds to a

$\beta$

-plane approximation at the equator, and the second to a

$\gamma$

approximation, with the latter describing flow near the poles. We find exact wave solutions in the Lagrangian reference frame that cannot be written down in closed form in the Eulerian reference frame. The wave particle trajectories, contours of potential vorticity and Lagrangian mean velocity take relatively simple forms. The waves possess a non-trivial Lagrangian mean flow that depends on the amplitude of the waves and on a particle label that characterizes values of constant potential vorticity. The mean flow arises due to potential vorticity conservation on fluid particles. Solutions over the entire space are generated by assuming that the flow far from the origin is zonal and there is a region of uniform potential vorticity between this zonal flow and the waves. In the

$\gamma$

approximation, a class of waves is found that, based on analogous solutions on the plane, we call Ptolemaic vortex waves. The mean flow of some of these waves, which we can describe in highly nonlinear scenarios due to the exact nature of the solutions, resembles polar jet streams. Several illustrative solutions are used as initial conditions in the fully spherical rotating Navier–Stokes equations, where integration is performed via the numerical scheme presented in Salmon & Pizzo (Atmosphere, vol. 14, issue 4, 2023, 747). The potential vorticity contours found from these numerical experiments vary between stable permanent progressive form and fully turbulent flows generated by wave breaking.
On the strong stability of ergodic iterations
Authors: Györfi László , Lovas Attila , Rásonyi Miklós
Published: November 2024

We revisit processes generated by iterated random functions driven by a stationary and ergodic sequence. Such a process is called strongly stable if a random initialization exists for which the process is stationary and ergodic, and for any other initialization the difference of the two processes converges to zero almost surely. Under some mild conditions on the corresponding recursive map, without any condition on the driving sequence we show the strong stability of iterations. Several applications are surveyed such as generalized autoregression and queuing. Furthermore, new results are deduced for Langevin-type iterations with dependent noise and for multitype branching processes.
WISE J152614.95-111326.4, an unusual variable star
Authors: Koen Chris , Kniazev Alexei Y.
Published: November 2024

New time series photometry of WISE J152614.95-111326.4, an eclipsing binary candidate, has been obtained. Full cycles of variation were covered in five filters, ranging from B to z. Archival time series photometry is also available from several sources. The phased light curve shape changes from a double wave form in the red, to a single wave at shorter wavelengths. Analysis of the spectral energy distribution and SALT spectra shows the presence of a cool (

$\sim$

7 250–7 900 K) white dwarf and an M6 star. The light curves can be explained by a hot spot on the opposing hemisphere of the white dwarf. The star may be in a pre-cataclysmic variable phase with a very low rate of mass flow from the red dwarf to the white dwarf, such that no flickering is evident. Evidence in favour of this hypothesis is that the period of the system (2.25 h) is in the cataclysmic variable period gap. It is speculated that a weak magnetic field associated with the white dwarf funnels accreted material onto a magnetic pole. Amplitudes of the W1 and W2 WISE light curves are anomalously large. The possibility is discussed that variability in this spectral region is primarily driven by electron cyclotron radiation.
Explanatory Stabilization in Situations of Evidential Uncertainty
Authors: Schindler Samuel
Published: November 2024

In this article I issue a challenge to what I call the Independence Thesis of Theory Assessment (ITTA). According to ITTA, the evidence for (or against) a theory must be assessed independently from the theory explaining the evidence. I argue that ITTA is undermined by cases of evidential uncertainty, in which scientists have been guided by the explanatory power of their theories in the assessment of the evidence. Instead, I argue, these cases speak in favor of a model of theory assessment in which explanatory power may indeed contribute to the stabilization of the evidential basis.
Internalist and Integrationist Theories of (Global) Justice
Authors: KNIESS JOHANNES
Published: November 2024

The global justice debate has increasingly moved toward the analysis of concrete issues in global politics, such as trade, migration, or climate change. This raises a methodological question: should the demands of justice in these domains be theorized independently or in conjunction with one another? Integrationists have championed the latter approach, arguing that it is better suited to guide our practical judgments. In contrast, internalists maintain that each domain is governed by its own set of principles. This paper defends the plausibility of the internalist approach against integrationist challenges. By examining different interpretations of internalism, it first seeks to provide a clearer overview of the methodological dispute. It then analyzes various arguments for integrationism, showing that their implications are more limited than their proponents believe. Finally, it focuses on the question of practical guidance, highlighting the value of idealized domain-specific theorizing in guiding transitions toward just arrangements.
Weight loss maintenance in primary health care: a randomised controlled trial
Authors: de Freitas Patrícia Pinheiro , Lopes Mariana Souza , Lopes Aline Critine Souza
Published: November 2024

This study evaluates the maintenance of a clinically meaningful weight loss (≥ 5 %) after 12 and 36 months of participation in an intervention to promote fruit and vegetable (FV) consumption. A randomised controlled trial was conducted in a primary health care service. For 7 months, participants in the control group (CG) and in the intervention group (IG) performed guided physical exercise three times/week; the IG also participated in collective activities to promote FV consumption. This study selected participants (n 267) who showed clinically meaningful weight loss after nutritional intervention. Sociodemographic, health and body weight data were collected in a face-to-face interview at baseline (T0) and after intervention (T1). Participants were reassessed after 12 (T2) and 36 months (T3) by telephone interview, and the self-reported weight was corrected. The outcome measures weight changes at three time points: M1, comparing T2 with T1; M2, comparing T3 with T2; and M3, comparing T3 with T1. The generalised estimating equation, adjusted for individual characteristics, was used. Participants in the CG showed an increase of 4·2 kg (P < 0·001) at M1 and 4·6 kg (P < 0·001) at M3, while IG individuals showed an increase of 3·6 kg (P < 0·001) at M1 and 3·8 kg (P < 0·001) at M3. The between-group analyses show the effect of nutritional intervention on the maintenance of weight loss at M2 (P = 0·033). Although CG and IG participants increased in weight, the nutritional intervention was associated with maintenance over the long term. This reveals the importance of the promotion of FV consumption for body weight maintenance.
New record and phylogenetic assessment of Apopharynx bolodes (Braun, 1902) (Digenea: Psilostomidae), a parasite of Eurasian Coot Fulica atra Linnaeus, 1758 (Aves: Rallidae)
Authors: Vlasenkov S.A. , Akimova L.N. , Sokolov S.G.
Published: November 2024

Phylogenetic studies of aberrant species are of considerable scientific interest because their taxonomic rank in traditional systems based on morphological characters is not infrequently overestimated. Apopharynx bolodes (Braun, 1902) is one of the few psilostomid digeneans devoid of the pharynx. This is considered a sufficient basis for assigning it and similar species to the subfamily Apopharynginae. We found A. bolodes in Fulica atra Linnaeus, 1758 from Belarus, described it morphologically, and genotyped it by the 28S rRNA gene and the ITS2 region. It is the first molecular data on A. bolodes and the first record of this digenean species in Belarus. The phylogenetic analysis based on partial sequences of the 28S rRNA gene showed that A. bolodes is closely related to the Sphaeridiotrema spp. (Sphaeridiotrematinae). However, this phylogenetic inference has not received yet support with data on the ITS2 region.
Narrowing gender gap in the research on echinococcosis and editorial contribution of women in parasitology journals
Authors: Kaveh R. , Ashrafhesari N. , Mousavi S.M. , Fasihi Harandi M.
Published: November 2024

Gender equity and authorship diversity are believed to be the essential parts of building a dynamic scientific atmosphere. The purpose of the present study was to determine the status of gender equity in research on echinococcosis and the editorial diversity in major parasitology journals over the past four decades. All articles were retrieved from major databases from the years 1980, 2000, 2010, 2015, and 2020. Journals belonging to the four quartiles of parasitology journals listed in the Journal Citation Report were selected, and the gender and region of each editorial member were identified. Among the 3583 first authors of the articles published in all selected years, 2236 (62.4%) were men, whereas 1040 (29%) were women. There was a significant increase in women’s contributions as the first author, from 6.8% in 1980 to 35.8% in 2020 (P < .001). A greater gender gap was found for the senior authors, showing 2391 (66.7%) men and 837 (23.4%) women. The gender gap has been narrowed in most of the six regions of the world, particularly for the Western Pacific region, where the gender inequity had almost diminished in 2020; i.e. the man-woman ratios of the first and last authors from this region were 2.25 and 1.75 in 1980, reaching 1.04 and 0.97, in 2020, respectively. Our findings also indicated that articles authored by men received 2.5 to 3.1 times more citations than women authors. Gender distribution of the editors-in-chief, associate editors, and editorial board members across all quartiles showed that 78.7%, 69.5%, and 72.7% were men, respectively, and mostly affiliated with the European and American regions. Findings of the present study showed that gender inequity is still present and women researchers continue to be the minority in the field of parasitology, particularly in the research on echinococcosis.
Even more happiness in hell
Authors: Lembke Martin
Published: November 2024

Published in 1892, St. George Jackson Mivart’s remarkably original article ‘Happiness in Hell’ was placed on the Index Librorum Prohibitorum almost immediately. In his article, Mivart proposed a solution to the problem of hell whose core contention is that hell is horrible only from a heavenly point of view. From a this-worldly point of view, by contrast, hell is a place of breathtaking felicity. In my opinion, this proposal has some striking merits, at least if it is updated and developed in certain respects. The purpose of this article is to reconstruct it, to reassess it, and to put it back on the table of eschatological ideas.
Can pantheism explain the existence of the universe?
Authors: Oberle Thomas
Published: November 2024

Many traditional theists maintain that God is the ultimate explanation of the universe, for why anything exists at all. For the traditional theist, only a being who is fundamental and transcendent can provide an ultimate ground and explanation of the universe. This requirement that God transcend the universe in order to ultimately explain it poses a challenge for pantheism, the view that God is numerically identical with the universe. If God is identical with the universe, and God is supposed to be the ultimate explanation of the universe, the result is an instance of circular explanation. And circular explanations are allegedly illegitimate. In this article, I develop two explanatory models in an attempt to show that pantheism is consistent with non-circular explanations of the universe. All else being equal, I argue that pantheism is not explanatorily deficient in comparison to traditional theism.
Alexander and empire: a commentary on a new testimony to Onesicritus (Sen. Ben. 7.2.5)
Authors: Degen Julian
Published: November 2024

This article is a commentary on a recently discovered testimony to Onesicritus, in which the writer speaks about his role as participant in the expedition of Alexander. It will be argued that the ideological backdrop of the testimony was Alexander’s claim to universalism, which was intended to be a response to the ancient Near Eastern discourse on empire. Alexander adopted ideological concepts of successful rulership used by the Achaemenids in order to stabilize control in Asia. For this purpose, he claimed to have carried his conquest to the Ocean, which implied universalism. That claim was the main theme in Onesicritus’ account and established the literary atmosphere in which the writer determined his role during the navigation of the Indian Ocean.
Gauging the effectiveness of a mobile application for learning English phrasal verbs
Authors: Alhujaylan Hailah
Published: November 2024

This study used a mixed-methods approach to evaluate the efficacy of mobile-assisted language learning (MALL) in teaching English phrasal verbs (PVs) in a 12-week study. The participants were 122 EFL college students divided equally into an experimental and a control group. The experimental group was assigned PV learning on an iOS-based application (henceforth referred to as “app”) for eight weeks; the control group learned the same PVs through paper-based material. Pre-tests, post-tests, and weekly class tests were conducted, and one-way ANOVAs were performed to evaluate the differences between the two groups using their pre-test and post-test scores, with repeated measures ANOVA used to analyse the learning gains in weekly tests. The results revealed that the experimental group significantly outperformed the control group in the post-test (F = 6.09, p = .015, Cohen’s d = 0.45) and weekly tests (F = 31.68, p = .000). A Likert-scale-based e-questionnaire consisting of 19 items was administered to the experimental group to obtain their perceptions of the app’s usefulness for learning English PVs. The overall results suggest that MALL, particularly with this specific mobile app, may enhance students’ ability to understand and use English PVs, a key aspect of vocabulary skills. The findings can be used to encourage instructors to employ MALL for teaching the English lexicon for better learning outcomes in EFL settings.
Whiteness, Curriculum, and the Infrastructures of Victorian Studies
Authors: Hsu Sophia
Published: November 2024

This essay makes a case for viewing curriculum and the historical assemblages of slavery, racialization, and migration as infrastructures of Victorian literary studies. It does so by taking the recent curricular revision that the English department at Lehman College, a public, Hispanic-Serving Institution in the Bronx, New York, underwent as its starting point. I reflect on how this curricular overhaul, which was catalyzed by student activism, helped me see not only how curriculum has operated as an infrastructure of whiteness in my department and English studies at large but also how disentangling Victorian studies from its white Anglo assumptions will require reconceptualizing the methodological, epistemological, and historical foundations of the field.
Riding Jane Eyre's Stagecoach Rhythm in Jane Re's New York Subway
Authors: Kim Jungah
Published: November 2024

In the Victorian era, innovations in infrastructure, notably the revolutionary stagecoach, redefined women's travel experiences and offered them a means to break free from domesticity. While the rapid pace of the stagecoach initially unsettles individuals like Jane Eyre in Charlotte Brontë's Jane Eyre (1847), she accustoms herself to its motion to evade perilous situations. Bearing in mind the cadence of the stagecoach, I suggest that Patricia Park's modern retelling of Jane Eyre, Re Jane (2015), adapts the rhythm of the coach by recasting it as the motion of the New York City subway. Revising in this way, Park incorporates positive racial representation through the subway and its passengers. By re-creating the rhythm of the coach through the subway train, Park considers two historical ideas: the New York City subway was built by racial and ethnic minorities such as Irish immigrants and African Americans, and the subway also softly calls back to the beginnings of the American transcontinental railroad that erased the visibility of Chinese immigrant laborers. This essay contends that the transportation systems in nineteenth-century England and twenty-first-century New York created changes that liberated women from the rooted domestic ideologies of their respective periods.
Climate Period. Punctuation as Infrastructure
Authors: Leckie Barbara
Published: November 2024

This paper considers fossil fuel infrastructure alongside the punctuation infrastructure of writing. It focuses, in particular, on the period—as both punctuation and time frame—to ask how one demarcates the Victorian period in the context of climate change impacts that exceed it. The paper itself traverses different temporal periods and different forms of punctuation to make its point that infrastructure, while often unnoticed, shapes both ideas and action.
Heredity's Aesthetic Infrastructures
Authors: Wong Amy R.
Published: November 2024

This essay traces a disjointed aesthetics of hereditary units in Thomas Hardy's Jude the Obscure (1895) and Chinese filmmaker Wang Xiaoshuai's So Long, My Son (2019) and argues that shared social and economic conditions of Victorian Britain and postsocialist China prompt similar ruptures of social realism's totalizing aspirations. The novel and the film are mutually concerned with tragedies of biopolitical management and doomed lineages, but at the same time they both employ an aesthetics of leapings and projections—also featured in Hardy's 1917 poem “Heredity”—that argues for the value of an individual life based on a radical divestment from personhood itself, in favor of the gene's mindless jumps through unmapped space and time.
Sultana Dreams of Infrastructure
Authors: Wickes Briony , Williams Rhys
Published: November 2024

This article examines Rokeya Hossain's “Sultana's Dream” (1905), a short story that pictures a solar-powered utopia governed by women, as a key site for thinking through the entanglements of sovereignty, gender, colonization, and environmental relations as they are articulated through infrastructure. To read infrastructurally in this way, we attend to socio-historical contexts of nineteenth-century Bengali society and to the Victorian imperial roots of early solar inventions, alongside the more modular aesthetics and meaning-making affordances of solar energy. Such a mode of reading makes infrastructure legible as an essential political ground for the maintenance or transformation of socio-ecological relations and reveals the irreducible political, material, and poetic qualities of infrastructures themselves. Texts like “Sultana's Dream” make such configurations visible and open to interrogation, and demonstrate the ways that solar, as infrastructure, energizes new social and political forms—even those yet undreamed.

Objectives

The primary aims of this multicenter, prospective observational study were to investigate spiritual well-being, resilience, and psychosocial distress in an Italian sample of glioblastoma patients undergoing radiochemotherapy. The secondary aim was to explore the influence of demographic, clinical, and psychological characteristics on survival.

Methods

The assessment was conducted only once, within the first week of radiochemotherapy treatment. Spiritual well-being was evaluated by the Functional Assessment of Chronic Illness Therapy-Spiritual Well-being (FACIT-Sp-12), and religious/spiritual beliefs and practices were evaluated by the System of Belief Inventory. Resilience was evaluated by the Connor−Davidson Resilience Scale (CD-RISC). Psychosocial distress was evaluated the by Distress Thermometer and Hospital Anxiety Depression Scale. We conducted an univariable analysis of overall survival (OS) using data from the most recent follow-up available, considering demographic and clinical variables that could influence survival. Follow-up was defined as either the time of death or the latest follow-up visit recorded.

Results

We recruited 104 patients, and the median follow-up time was 18.3 months. “Distressed” patients had lower scores than “not distressed” patients on the FACIT-Sp-12 and CD-RISC. While OS was not significant according to the FACIT-Sp-12 threshold, the Kaplan−Meier log-rank test was 0.05 according to the CD-RISC threshold. Among demographic variables, age showed significant associations with OS (p = 0.011). Resilience showed significant associations with OS (p = 0.025).

Significance of results

Data showed that high spiritual well-being was associated with high resilience and an absence of psychosocial distress in our sample of glioblastoma patients undergoing radiochemotherapy. Patients with greater resilience survived longer than those with lesser resilience. Profiling spiritual well-being and resilience in glioblastoma patients undergoing radiochemotherapy can be seen as a resource to identify novel characteristics to improve clinical take-in-charge of glioblastoma patients.
Longitudinal Fluvial Dispersion of Coarse Particles: Insights From Field Observations and Model Simulations
Authors: Yadav Anshul , Hassan Marwan A. , McDowell Conor , Bradley D. Nathan , Sen Sumit
Published: November 2024

In this study, we use field observations augmented with model simulations to examine gravel dispersion over nine years (2007–2015) in Halfmoon Creek. The observations of flow, entrainment, and dispersion were used to develop a forward model utilizing the Einstein‐Hubbell‐Sayre (EHS) compound Poisson process. The observed mean virtual velocity of the tracer population slows down with cumulative excess energy after the 2010 large event. The forward model deviates from the observations in representation of tails, overpredicts mean displacements, and shows a narrower spatial distribution. The heavy‐tailed resting times indicate prolonged immobilization of some grains, suggesting the preferential movement of other most mobile grains. As such, 34% of most mobile grains constitute 50% of the total entrainments. The consideration of preferential movement explains the longitudinal spread but still overpredicts the displacement after the 2010 event. The model was then explored to consider additional transport‐related mechanisms causing deviations, such as reduction in virtual velocity, entrainment probability, and morphological trapping of meander bends, which helps to adequately recreate the observed dispersive behavior. The available historical flow records used for simulating dispersive behavior over multiple decades reveal an abrupt increase in displacements for exceptionally large events, suggesting the exhumation of deeply buried grains back in transport. The simulation results highlight the need for tracer studies with large sample sizes and improved recovery rates for longer time frames experiencing floods of widely varying magnitudes. Such models, inspired by Einstein's stochastic theory can be valuable for various river research applications.

Published: November 2024

Drylands are critical in regulating global carbon sequestration, but the resiliency of these semi‐arid shrub, grassland and forest systems is under threat from global warming and intensifying water stress. We used synergistic satellite optical‐Infrared (IR) and microwave remote sensing observations to quantify plant‐to‐stand level vegetation water potentials and seasonal changes in dryland water stress in the southwestern U.S. Machine‐learning was employed to re‐construct global satellite microwave vegetation optical depth (VOD) retrievals to 500‐m resolution. The re‐constructed results were able to delineate diverse vegetation conditions undetectable from the original 25‐km VOD record, and showed overall favorable correspondence with in situ plant water potential measurements (R from 0.60 to 0.78). The VOD water potential estimates effectively tracked plant water storage changes from hydro‐climate variability over diverse sub‐regions. The re‐constructed VOD record improves satellite capabilities for monitoring the storage and movement of water across the soil‐vegetation‐atmosphere continuum in heterogeneous drylands.
Long‐Term Temperature Impacts of the Hunga Volcanic Eruption in the Stratosphere and Above
Authors: Randel William J. , Wang Xinyue , Starr Jon , Garcia Rolando R. , Kinnison Douglas
Published: November 2024

Global average upper atmosphere temperature changes linked with the Hunga volcanic eruption (January 2022) are analyzed based on satellite measurements and compared with chemistry‐climate model simulations. Results show stratospheric cooling of −0.5 to −1.0 K in the middle and upper stratosphere during 2022 through middle 2023, followed by stronger cooling (−1.0 to −2.0 K) in the mesosphere after middle 2023. The cooling patterns follow the upward propagating water vapor (H2O) anomalies from Hunga, and similar behavior is found between observations and model simulations. While the stratospheric cooling is mainly due to radiative cooling from enhanced H2O, the mesospheric temperature changes result from ozone losses in the mesosphere, which are in‐turn driven by HOx radicals from Hunga H2O. Comparisons with the multi‐decade climate record show that Hunga impacts on stratospheric temperatures have similar magnitude, but opposite sign, to temperature effects from the large El Chichón (1982) and Pinatubo (1991) volcanic eruptions.
Bottom Stress and Drag on a Shallow Coral Reef

Published: November 2024

Coral reef roughness produces turbulent boundary layers and bottom stresses that are important for reef metabolism monitoring and reef circulation modeling. However, there is some uncertainty as to whether field methods for estimating bottom stress are applicable in shallow canopy environments as found on coral reefs. Friction velocities () and drag coefficients () were estimated using five independent methods and compared across 14 sites on a shallow forereef (2–9 m deep) in Palau with large and spatially variable coral roughness elements (0.4–1 m tall). The methods included the following: (a) momentum balance closure, (b) log‐fitting to velocity profiles, (c) Reynolds stresses, (d) turbulence dissipation, and (e) roughness characterization from digital elevation models (DEMs). Both velocity profiles and point turbulence measurements indicated good agreement with log‐layer scaling, suggesting that measurements were taken within a well‐developed turbulent boundary layer and that canopy effects were minimal. However, estimated from the DEMs, momentum budget and log‐profile fitting were consistently larger than those estimated from direct turbulence measurements. Near‐bed Reynolds stresses only contributed about 1/3 of the total bottom stress and drag produced by the reef. Thus, effects of topographical heterogeneity that induce mean velocity fluxes, dispersive stresses, and form drag are expected to be important. This decoupling of total drag and local turbulence implies that both rates of mass transfer as well as values of fluxes inferred from concentration measurements may be proportional to smaller, turbulence‐derived values of rather than to those based on larger‐scale flow structure.
Stratospheric Transit Time Distributions Derived From Satellite Water Vapor Measurements
Authors: Randel William J. , Podglajen Aurelien , Wu Fei
Published: November 2024

Stratospheric transit time distributions (age‐of‐air spectra) are estimated using time series of satellite water vapor (H2O) measurements from the Microwave Limb Sounder over 2004 to 2021 assuming stationary transport. Latitude‐altitude dependent spectra are derived from correlations of interannual H2O anomalies with respect to the tropical tropopause source region, fitted with an inverse Gaussian distribution function. The reconstructions accurately capture interannual H2O variability in the “tropical pipe” and near‐global lower stratosphere, regions of relatively fast transport (∼1–2 years) in the Brewer‐Dobson circulation. The calculations provide novel observational estimates of the corresponding “short transit‐time” part of the age spectrum in these regions, including the mode. However, the H2O results do not constrain the longer transit‐time “tail” of the age spectra, and the mean age of air and spectral widths are systematically underestimated compared to other data. We compare observational results with parallel calculations applied to the WACCM chemistry‐climate model and the CLaMS chemistry‐transport model, and additionally evaluate the method in CLaMS by comparing with spectra from idealized pulse tracers. Because the age spectra accurately capture H2O interannual variations originating from the tropical tropopause, they can be used to identify “other” sources of variability in the lower stratosphere, and we use these calculations to quantify H2O anomalies in the Southern Hemisphere linked to the Australian New Years fires in early 2020 and the Hunga volcanic eruption in 2022.
Intensified Western Pacific Convection Increases the Probability of Hot Extremes in the Middle East During the Boreal Spring
Authors: Xia Ming , Yang Song , Wei Wei , Fan Hanjie , Lin Shuheng , Deng Kaiqiang
Published: November 2024

Under global warming, the convective heating over the western Pacific (WP) has exhibited a significantly intensifying trend during the boreal spring, while the surface air temperatures in the Middle East (ME) have increased more rapidly than those in other tropical regions. Are these climate phenomena of the two regions physically connected? If yes, what are the responsible dynamical mechanisms involved? Utilizing the ERA5 reanalysis data and model simulations, this study reveals a significant seesaw variation in the convection and temperature trends between WP and ME. When convective heating intensifies over the WP, the ME tends to be drier and hotter during the spring, and vice versa. A further investigation indicates that the enhanced WP convective heating can induce anticyclonic circulation anomalies in the upper and middle troposphere over the Iranian and Tibetan plateaus. These anomalous high pressures extend westward, exhibiting a barotropic structure, which leads to stronger sinking motions, reduced cloud cover, and increased surface solar radiation over the ME. Consequently, these conditions result in drier and hotter soils and an increase in heatwave days in the ME. This study provides useful information for enhancing our understanding of the role of tropical WP climate change in influencing the upstream climate conditions with a focus on the ME.
Estimating Primary Magmas From Mars With PRIMARSMELT: Implications for the Petrogenesis of Some Martian Rocks and the Thermal Evolution of Mars
Authors: Hernández‐Montenegro Juan David , Asimow Paul D. , Herzberg Claude T.
Published: November 2024

Primary magmas form by partial melting in the mantle of a terrestrial planet and represent the starting material for building its crust. The compositions of primary magmas are critical for understanding the thermal history of planetary interiors, as they can be used to estimate mantle potential temperatures (TP) and track changes in the conditions of mantle partial melting over time. Here, we introduce PRIMARSMELT, a new member of the PRIMELT software family, calibrated to estimate the composition of Martian primary magmas and their formation conditions. We applied PRIMARSMELT to a comprehensive database of basaltic compositions from Mars. Our results are consistent with their petrology, requiring olivine addition to restore fractionated compositions to their primary parents and olivine subtraction from cumulate rocks. Individual primary magma solutions provide insights into the petrogenesis of specific Martian meteorites, with implications for the near‐primary nature of some primitive meteorites and the relationship between lithologies A and B in meteorite EETA 79001. Taken together, our results suggest nearly constant or potentially increasing mantle potential temperatures throughout the geological history of Mars. The average TP for young shergottite meteorites is ∼1,442 ± 40°C, similar to ambient mantle temperatures inferred from geophysical models. In contrast, older basaltic rocks record potential temperatures as low as ∼1,320 ± 48°C for igneous clasts in meteorites NWA 7034/7533. We suggest that, rather than plume‐related magmatism, shergottite meteorites record ambient mantle temperatures, with the thermal evolution trend possibly resulting from inefficient heat loss, as expected for a planet in stagnant‐lid mode.

In many regions of the world with complex seismic activity, the availability of seismic stations is limited. This motivated us to develop a probabilistic method for single‐station earthquake location. Single station location methods may provide an efficient and cost‐effective way to monitor small‐magnitude seismic events over large areas of the world. This method relies on the outputs of two neural networks, which predict the initial spatial location of specific areas (convolutional) used in the prior probability and seismic phase recognition (combination of convolutional and Long Short Term Memory) used in the likelihood function. These estimates and a 3D travel time likelihood function are used in a Bayesian framework. In this model, the initial spatial location is expressed as a Multivariate Gaussian Mixture Model, and the likelihood function refines the localization using the arrival time difference between S and P waves in a 3D space. The likelihood function uses a Fast Marching Eikonal method with a 3D velocity structure. We tested this method on the Ridgecrest 2019 seismic sequence (Mw = 7.1) and on West Texas and found promising results for locating with a single station. Our approach demonstrates that using a Bayesian model with strong priors obtained through deep learning algorithms is effective. Our model can predict epicenter and depth with mean errors of 7.55 km in longitude, 13.54 km in latitude and 0.630 km in depth at the two different locations studied. This method demonstrates the effectiveness of combining deep learning for initial estimations with probabilistic 3D location refinement.

Objectives

To examine the association of novel furosemide versus thiazide diuretic exposure with changes in serum sodium, potassium, and chloride levels among infants with grade 2/3 bronchopulmonary dysplasia (BPD).

Study Design

Retrospective cohort study of infants admitted to a level IV neonatal intensive care unit (NICU) with grade 2/3 BPD. We measured within-subject change in serum sodium, potassium, and chloride before and after diuretic initiation using multivariable regression to adjust for differences in dosing and clinical covariates.

Results

We identified 94 infants contributing 137 novel diuretic exposures. No significant difference was noted in the association between chlorothiazide versus furosemide and serum sodium, potassium, or chloride change in multivariable modeling.

Conclusions

Changes in serum electrolytes were similar for chlorothiazide and furosemide, questioning the perception that chlorothiazide leads to less electrolyte derangement among preterm infants with grade 2/3 BPD.

MEMS gyroscopes are well known for their outstanding advantages in Cost Size Weight and Power (CSWaP), which have inspired great research attention in recent years. A higher signal-to-noise ratio (SNR) for MEMS gyroscopes operating at larger vibrating amplitudes provides improved measuring resolution and ARW performance. However, the increment of amplitude causes strong nonlinear effects of MEMS gyroscopes due to their micron size, which has negative influences on the performance. This paper carries out detailed research on a general nonlinear mechanism on the sensors using parallel-plate capacitive transducers, which is called the gain nonlinearity in electrostatic actuation. The theoretical model established in this paper demonstrates the actuation gain nonlinearity causes the control-force coupling and brings extra angle-dependent bias with the 4th component for the whole-angle gyroscopes, which are verified by the experiments carried out on a micro-shell resonator gyroscope (MSRG). Furthermore, a real-time correction method is proposed to restore a linear response of the electrostatic actuation, which is realized by the gain modification with an online parameter estimation based on the harmonic-component relationship of capacitive detection. This real-time correction method could reduce the 4th component of the angle-dependent bias by over 95% from 0.003°/s to less than 0.0001°/s even under different temperatures. After the correction of actuation gain nonlinearity, the bias instability (BI) of whole-angle MSRG is improved by about 3.5 times from 0.101°/h to 0.029°/h and the scale factor nonlinearity (SFN) is reduced by almost one order of magnitude from 2.02 ppm to 0.21 ppm.

Polycomb repressive complex 2 (PRC2) catalyzes the writing of the tri-methylated histone H3 at Lys27 (H3K27me3) epigenetic marker and suppresses the expression of genes, including tumor suppressors. The function of the complex can be partially antagonized by the SWI/SNF chromatin-remodeling complex. Previous studies have suggested that PRC2 is important for the proliferation of tumors with SWI/SNF loss-of-function mutations. In the present study, we have developed an EED-directed allosteric inhibitor of PRC2 termed BR0063, which exhibits anti-proliferative properties in a subset of solid tumor cell lines harboring mutations of the SWI/SNF subunits, SMARCA4 or ARID1A. Tumor cells sensitive to BR0063 exhibited several distinct phenotypes, including cell senescence, which was mediated by the up-regulation of CDKN2A/p16. Further experiments revealed that the expression of p16 was suppressed in the BR0063-resistant cells via DNA hypermethylation in the CpG island (CGI) promoter region, rather than via PRC2 occupancy. The expression of TET1, which is required for DNA demethylation, was found to be inversely correlated with p16 CGI methylation, and this may serve as a biomarker for the prediction of resistance to PRC2 inhibitors in SWI/SNF LOF tumors.

Dysfunction of zinc finger protein 652 (ZNF652) is associated with various malignant tumors. However, the role of ZNF652 in lung cancer (LC) is poorly understood. Here, we identified that ZNF652 was downregulated in human LC tissues and cell lines. Low ZNF652 expression was associated with poor survival in LC patients. Overexpression of ZNF652 inhibited cell viability, proliferation, migration, and invasion of LC cells, whereas ZNF652 knockdown promoted these malignant phenotypes. Using RNA-seq analysis revealed that ZNF652 overexpression resulted in obvious alterations of various biological processes, especially cell cycle and cellular senescence. Subsequently, we confirmed that ZNF652 overexpression arrested the cell cycle at the G1 phase, increased ROS-mediated DNA damage, induced LC cell senescence, and enhanced cisplatin-induced apoptosis in LC cells. Mechanistically, ZNF652 directly bound to the promoter of cyclin D3 (CCND3), inhibited its transcription, thereby arresting the cell cycle at the G1 phase. Ectopic expression of cyclin D3 rescued the decreased cell viability and cell cycle arrest induced by ZNF652. In vivo studies further showed that ZNF652 overexpression suppressed the tumorigenic potential of LC. Collectively, our findings reveal that ZNF652 exerts a tumor suppressor role in lung cancer by inducing cell cycle arrest and cellular senescence via transcriptionally downregulating cyclin D3. Thus, ZNF652 may be a prognostic predictive factor for LC patients.

Published: November 2024

Background

There is extensive evidence that rapid infant weight gain increases the risk of childhood obesity, but this is normally based on childhood body mass index (BMI) only and whether or not this is because infants with rapid weight gain accrue greater fat mass is unknown.

Objective

The primary objective of our study was to test whether the proportion of infant weight gain due to concurrent increases in fat mass is greater in infants with rapid weight gain as compared to those with normal growth.

Methods

Body composition was assessed by (1) air-displacement plethysmography (ADP) at 0 and 6 months in 342 infants from Australia, India, and South Africa and (2) deuterium dilution (DD) at 3 and 24 months in 555 infants from Brazil, Pakistan, South Africa, and Sri Lanka. Weight gain and length growth were each categorized as slow, normal, or rapid using cut-offs of <−0.67 or >+0.67 Z-scores. Regression was used to estimate and contrast the percentages of weight change due to fat mass change.

Results

Approximately 40% of the average weight gain between 0 and 6 months and 20% of the average weight gain between 3 and 24 months was due to increase in fat mass. In both samples, compared to the normal group, the proportion of weight gain due to fat mass was higher on average among infants with rapid weight gain and lower among infants with slow weight gain, with considerable individual variability. Conversely, slow and rapid length growth was not associated with differential gains in fat mass.

Conclusions

Pediatricians should monitor infant growth with the understanding that, while crossing upward through the weight centiles generally is accompanied by greater adiposity gains (not just higher BMI), upward crossing through the length centiles is not.
