Escrevivência as a Theory of Diasporic Narrative Heritage
Authors: Mullaney William 
Published: October 2024

AbstractThis article studies a theoretical term for diasporic cultural production proposed by the contemporary Black Brazilian writer Conceição Evaristo—escrevivência. Evaristo’s first novel, Becos da Memória ([2006] 2017)—semiautobiographical remembrances of a midcentury favela community during its eviction—exemplifies escrevivência as a theory of the transmission of a culture of resistance to imposed dispossession. The term has been cited in a proliferation of antiracist critiques and studies on marginal subjects in Brazil. My argument is that escrevivência is crucial for Brazilian decolonial thought, given the temporally recursive frame it enunciates, which opens the present and future to prior articulations of Black culture in Brazil. I make three approaches to Becos within escrevivência’s temporal frame, examining literary anteriority (the influence of Carolina Maria de Jesus’s works), narrated marginality (polyphony, embodiment, domestic labor, minor literature), and cultural heritage (the instantiation and circulation of Black language).

AbstractThe present systematic review and meta-analysis sought to evaluate the effects of conjugated linoleic acid (CLA) supplementation on cardiovascular risk factors in patients at risk of CVD. Relevant studies were obtained by searching the PubMed, SCOPUS and Web of Science databases (from inception to January 2023). Weighted mean differences (WMD) and 95% CI were pooled using a random-effects model. Heterogeneity, sensitivity analysis and publication bias were reported using standard methods. A pooled analysis of 14 randomised controlled trials (RCT) with 17 effect sizes revealed that CLA supplementation led to significant reductions in body weight (WMD: −0·72 kg, 95% CI: −1·11, −0·33, P < 0·001), BMI (WMD: −0·22 kg/m2, 95% CI: −0·44, −0·00, P = 0·037) and body fat percentage (BFP) (WMD: −1·32 %, 95% CI: −2·24, −0·40, P = 0·005). However, there was no effect on lipid profile and blood pressure in comparison with the control group. In conclusion, CLA supplementation may yield a small but significant beneficial effect on anthropometric indices in patients at risk of CVD. Moreover, CLA seems not to have adverse effects on lipid profiles and blood pressure in patients at risk of CVD. It should be noted that the favourable effects of CLA supplementation on anthropometric variables were small and may not reach clinical importance.
Derived functors and Hilbert polynomials over regular local rings
Authors: Puthenpurakal Tony J. 
Published: October 2024

AbstractLet $(A,\mathfrak{m})$ be a regular local ring of dimension $d \geq 1$, I an $\mathfrak{m}$-primary ideal. Let N be a nonzero finitely generated A-module. Consider the functions
\begin{equation*}
t^I(N, n) = \sum_{i = 0}^{d}\ell(\text{Tor}^A_i(N, A/I^n)) \ \text{and}\ e^I(N, n) = \sum_{i = 0}^{d}\ell(\text{Ext}_A^i(N, A/I^n))
\end{equation*}of polynomial type and let their degrees be $t^I(N) $ and $e^I(N)$. We prove that $t^I(N) = e^I(N) = \max\{\dim N, d -1 \}$. A crucial ingredient in the proof is that $D^b(A)_f$, the bounded derived category of A with finite length cohomology, has no proper thick subcategories.

Published: October 2024

AbstractMastomys natalensis and M. coucha are commensal rodent species endemic to Africa. A recent taxonomic revision within Mastomys leaves the parasite–host list of M. natalensis questionable and that of M. coucha incomplete. The current study aimed to develop a better understanding of the ectoparasite diversity associated with the 2 distinct but closely related rodent species and to explore the influence of host and habitat type on ectoparasite infestations. Between 2014 and 2020, 590 rodents were trapped in 3 habitat types (village, agriculture and natural) across a wildlife-human/domestic animal interface. In total 48 epifaunistic species (45 ectoparasitic and 3 predatory) represented by 29 genera from 4 taxonomic groups (fleas, lice, mites and ticks) were recorded. Only 50% of the epifauna were shared between the 2 rodent species, with mites the most speciose taxon in both host species. The abundance of epifaunistic individuals, and also those of mites and fleas, were significantly higher on male M. natalensis, while ticks were significantly higher on reproductively active M. natalensis. For both rodent species, infestations by most epifaunistic taxa (on M. natalensis) and some taxa (on M. coucha) were significantly lower in the village as opposed to the less disturbed agricultural and natural habitat types. The study highlights the importance of host life history, even in closely related rodent species, in shaping parasite profiles and a loss of parasite diversity in more extreme anthropogenic habitats.
The City, the Neighborhood, and the Street: Toward a Global Urban Labor History?
Authors: Vergara Ángela 
Published: October 2024

AbstractLabor scholars have increasingly recognized the need to look beyond the workplace and explore where and how workers lived, socialized, shopped, or protested. The six books reviewed in this essay contribute to understanding how modern cities shaped the process of working-class formation as well as workers’ identity, experiences, and economic and material conditions. From different standpoints, these urban and labor histories of Paris, Mexico City, Miami, Port Said, Montevideo, and Santiago, Chile, demonstrate the impact of urban modernization, industrial capitalism, and migration on working families. By bringing together books from different regions and historiographical traditions, this essay also reflects on the possibilities and challenges of writing a global labor urban history.
Higher left ventricular stroke volume is associated with aortic dilatation in repaired tetralogy of Fallot patients
Authors: Kawasaki Yuki , Takajo Daiji , Gupta Pooja , Aggarwal Sanjeev 
Published: October 2024

AbstractAortic root dilation has been reported commonly after repair of tetralogy of Fallot. However, the rate and risk factors of progression of the dilation are not fully understood. This is a single-centre, retrospective study to assess the rate and factors associated with progressive dilatation of the aortic root in repaired tetralogy of Fallot patients using cardiac MRI. The presence of the significant aortic dilation and the progression of dilation between initial and follow-up cardiac MRI were examined. The study cohort comprised 72 patients with repaired tetralogy of Fallot. The median age at the initial cardiac MRI scan was 19.6 (interquartile range: 14.6–31) years, and the median follow-up interval was 4.3 (2.9–5.7) years. Median dimension of ascending aorta at initial and follow-up cardiac MRI was 27.0 (22.3–31.0) mm and 29.2 (25.0–32.1) mm, respectively. Significant aortic dilation (the percentage predicted ascending aorta ≥150%) was observed in 11 (15.2%) patients at the initial cardiac MRI and 24 (33.3%) at the follow-up cardiac MRI. The significant aortic dilation at follow-up cardiac MRI was associated with increased indexed left ventricular stroke volume (odds ratio 1.062, p = 0.023). Thirteen patients demonstrated the significant progressive dilation of aorta between initial and follow-up cardiac MRI. The progressive dilation was associated with left ventricular ejection fraction at initial cardiac MRI (odds ratio 1.135, p = 0.048). In patients with repaired tetralogy of Fallot, aortic dilation is common and progresses over time. Cardiac MRI is a valuable tool for identifying individuals at risk for progressive aortic dilation.

Abstract

Objective:
This study aimed to assess the association between emotional attitudes towards diabetes, eating behaviour styles and glycaemic control in outpatients with type 2 diabetes.

Design:
Observational study.

Setting:
Endocrinology Division of Hospital de Clínicas de Porto Alegre, Brazil.

Participants:
Ninety-one outpatients diagnosed with type 2 diabetes. Baseline assessments included data on clinical parameters, lifestyle factors, laboratory results, eating behaviour styles and emotional attitudes. All patients received nutritional counseling following diabetes recommendations. A follow-up visit was scheduled approximately 90 days later to evaluate changes in weight, medication dosages and glycated Hb (HbA1c) values. Patients were categorised based on their emotional attitude scores towards diabetes (positive or negative), and their characteristics were compared using appropriate statistical tests.

Results:
At baseline, no differences were observed in the proportion of patients with good glycaemic control, eating behaviour styles and emotional attitudes. However, patients with a positive attitude towards the disease exhibited a significantly better response in glycaemic control compared with the reference group (OR = 3·47; 95 % CI = 1·12, 10·75), after adjusting for diabetes duration, sex and medication effect score. However, when BMI was included in the model, the association did not reach statistical significance. Therefore, these results should be interpreted with caution.

Conclusions:
Patients with a positive attitude towards diabetes showed a greater reduction in HbA1c levels following nutritional counseling. However, baseline BMI could be a potential confounding factor.

Published: October 2024

AbstractObjectivesPatient dignity is a key concern during end-of-life care. Dignity Therapy is a person-centered intervention that has been found to support patient dignity interviews focused on narrating patients’ life stories and legacies. However, mechanisms that may affect utility of the Dignity Therapy have been little studied. In this study, we evaluate whether the extent to which patients are more communal in their interviews acts as a mechanism for increased patient dignity.MethodsWe analyzed the written transcripts from Dignity Therapy interviews with 203 patients with cancer over the age of 55 receiving outpatient palliative care (M = 65.80 years; SD = 7.45 years, Range = 55–88 years; 66% women). Interviews followed core questions asking patients about their life story and legacy. We used content-coding to evaluate the level of communion narrated in each interview, and mediation analyses to determine whether communion affected dignity impact.ResultsMediation analyses indicated that the extent to which patients narrated communion in their interview had a significant direct effect on post-test Dignity Impact. Communion partially mediated the effect of pre-test on post-test Dignity Impact. For both the life story and legacy segments of the session, narrating communion had a direct effect on post-test Dignity Impact.Significance of resultsNarrating communion serves as a mechanism for enhancing patient dignity during Dignity Therapy. Providers may consider explicitly guiding patients to engage in, elaborate on, communal narration to enhance therapeutic utility. In addition, encouraging patients with advanced illness to positively reflect on relationships in life may improve patient dignity outcomes in palliative and end-of-life care.

Published: October 2024

AbstractThe rate of rocket launches is accelerating, driven by the rapid global development of the space industry. Rocket launches emit gases and particulates into the stratosphere, where they impact the ozone layer via radiative and chemical processes. We create a three‐dimensional per‐vehicle inventory of stratospheric emissions, accounting for flight profiles and all major fuel types in active use (solid, kerosene, cryogenic and hypergolic). In 2019, stratospheric (15–50 km) rocket launch emissions were 5.82 Gg , 6.38 Gg O, 0.28 Gg black carbon, 0.22 Gg nitrogen oxides, 0.50 Gg reactive chlorine and 0.91 Gg particulate alumina. The geographic locations of launch sites are preserved in the inventory, which covers all active launch sites in 2019. We also report the emissions data from contemporary vehicles that were not launched in 2019, so that users have freedom to construct their own launch activity scenarios. A subset of the inventory—stratospheric emissions for successful launches in 2019—is freely available and formatted for direct use in global chemistry‐climate or Earth system models.
Advancing Subseasonal Surface Air Temperature and Heat Wave Prediction Skill in China by Incorporating Scale Interaction in a Deep Learning Model

Published: October 2024

AbstractAccurate subseasonal predictions of high surface air temperature (SAT) and heat wave events 10–30 days in advance are crucial for mitigating the risks of extreme weather; however, they pose a challenge for current operational models. In this study, we trained a convolutional neural network (CNN)‐based deep learning model to exploit the modulations in China's SAT by precursor signals across different timescales to improve predictions of future SAT and heat wave events. This CNN model demonstrated superior capability in capturing the evolution of SAT anomalies and the occurrence of heat wave events with forecast lead times beyond 20 days, compared with that of the operational models of the China Meteorological Administration and European Centre for Medium‐Range Weather Forecasts. Explainability analysis highlighted that subseasonal SAT predictability in China is driven primarily by large‐scale intraseasonal perturbations from both lower‐ and higher‐latitude regions of Eurasia and interannual variability.
Paleomagnetic Field Variability and Revised Chronostratigraphy of Bering Sea (IODP Expedition 323) Deep‐Sea Sediments During MIS 6–7 (130–144 ka)
Authors: Lund Steve , Mortazavi Emily , Stoner Joe , Okada Makoto 
Published: October 2024

AbstractWe have developed replicate paleomagnetic secular variation (PSV) records for MIS 6–7 (130–244 ka) from IODP Ex. 3 23 Sites 1,343, 1,344, and 1,345 (Bering Sea). We can correlate the PSV at all three sites and identify 90 inclination features and 64 declination features. We have developed relative paleointensity records for all three sites by normalizing the demagnetized natural remanence to magnetic susceptibility. Paleointensity highs/lows can be tied to the PISO‐1500 global oxygen‐isotope‐dated paleointensity record. This provides a significant increase in chronostratigraphic resolution for these sites. Only one excursion is recorded in the MIS 6–7 sediments of the Bering Sea—the Iceland Basin Excursion (∼196 ± 3 ka). Replicate records of the inclinations and declinations both flip quickly to reversed polarity directions, stay there for several hundred years and then flip quickly back to normal polarity directions. However, the inclination flips occur without significant declinations changes and visa versa. A statistical PSV study was carried out by averaging the data in 3 ky and 9 ky windows. There is a distinctive bimodal pattern to the angular dispersions with most time spent with low angular dispersion values (∼10°–15°), but there is an interval of more than 30 ky (185–220 ka) with angular dispersions averaging two to three times higher amplitudes (∼25°–35°). This interval also has low paleointensities and the Iceland Basin Excursion. This same, coupled pattern of high angular dispersion, low paleointensity, and excursions is noted synchronously in the central North Atlantic Ocean and may indicate a global pattern to the geomagnetic field.
Examining Tropical Convection Features at Storm‐Resolving Scales Over the Maritime Continent Region

Published: October 2024

AbstractGlobal Storm Resolving Models (GSRMs) provide a way to understand weather and climate events across scales for better‐informed climate impacts. In this work, we apply the recently developed and validated CAM (Community Atmosphere Model)—MPAS (Model for Prediction Across Scales) modeling framework, based on the open‐source Community Earth System Model (CESM2), to examine the tropical convection features at the storm resolving scale over the Maritime Continent region at 3 km horizontal spacing. We target two global numerical experiments during the winter season of 2018 for comparison with observation in the region. We focus on the investigation of the representations of the convective systems, precipitation statistics, and tropical cyclone behaviors. We found that regional‐refined experiments show more accurate precipitation distributions, diurnal cycles, and better agreement with observations for tropical cyclone features in terms of intensity and strength statistics. We expect the exploration of this work will further advance the development and use of the storm‐resolving model in precipitation predictions across scales.
The Global Atmospheric Energy Cycle in TaiESM1: Present and Future

Published: October 2024

AbstractThe Lorenz Energy Cycle (LEC) in the Taiwan Earth System Model Version 1 (TaiESM1) historical simulation is calculated and compared with ERA5 to evaluate the model performance from the thermodynamic aspect. The future change of LEC is accessed by comparing the SSP5‐8.5 and historical simulations in TaiESM1. TaiESM1 reasonably simulates the global mean, seasonal cycle, and spatial patterns of the energy reservoirs with larger values in the mean energy components and smaller in the eddy energy components. The energy cycle in TaiESM1 is about 35%–45% stronger than ERA5, except from December to February. The impact of global warming on the LEC is different at the vertical levels. The influence of meridional temperature gradient change is the dominant factor in the intensity of the energy cycle, and the change in static stability only contributes to the lower troposphere. Lifting the tropopause in the tropics increases the meridional temperature gradient and produces more zonal mean potential energy (PM) in the upper troposphere. PM is the primary driver of the LEC and leads to a more active energy cycle in the upper troposphere. As the tropical tropospheric depth increases and the mid‐latitude eddy activities become more active, more (less) energy is stored in the upper (lower) troposphere, and the energy conversion processes tend to become stronger (weaker) in the upper (lower) troposphere.
Characterization of Medusavirus encoded histones reveals nucleosome-like structures and a unique linker histone

Published: October 2024

AbstractThe organization of DNA into nucleosomes is a ubiquitous and ancestral feature that was once thought to be exclusive to the eukaryotic domain of life. Intriguingly, several representatives of the Nucleocytoplasmic Large DNA Viruses (NCLDV) encode histone-like proteins that in Melbournevirus were shown to form nucleosome-like particles. Medusavirus medusae (MM), a distantly related giant virus, encodes all four core histone proteins and, unique amongst most giant viruses, a putative acidic protein with two domains resembling eukaryotic linker histone H1. Here, we report the structure of nucleosomes assembled with MM histones and highlight similarities and differences with eukaryotic and Melbournevirus nucleosomes. Our structure provides insight into how variations in histone tail and loop lengths are accommodated within the context of the nucleosome. We show that MM-histones assemble into tri-nucleosome arrays, and that the putative linker histone H1 does not function in chromatin compaction. These findings expand our limited understanding of chromatin organization by virus-encoded histones.
Global influence of soil texture on ecosystem water limitation

AbstractLow soil moisture and high vapour pressure deficit (VPD) cause plant water stress and lead to a variety of drought responses, including a reduction in transpiration and photosynthesis1,2. When soils dry below critical soil moisture thresholds, ecosystems transition from energy to water limitation as stomata close to alleviate water stress3,4. However, the mechanisms behind these thresholds remain poorly defined at the ecosystem scale. Here, by analysing observations of critical soil moisture thresholds globally, we show the prominent role of soil texture in modulating the onset of ecosystem water limitation through the soil hydraulic conductivity curve, whose steepness increases with sand fraction. This clarifies how ecosystem sensitivity to VPD versus soil moisture is shaped by soil texture, with ecosystems in sandy soils being relatively more sensitive to soil drying, whereas ecosystems in clayey soils are relatively more sensitive to VPD. For the same reason, plants in sandy soils have limited potential to adjust to water limitations, which has an impact on how climate change affects terrestrial ecosystems. In summary, although vegetation–atmosphere exchanges are driven by atmospheric conditions and mediated by plant adjustments, their fate is ultimately dependent on the soil.
