Published: September 2023

AbstractAggression plays a crucial role in deterring predators and securing resources to promote fitness. Nevertheless, studies focussing on female aggression remain scarce. In songbirds, aggression is prevalent during the breeding season, when same-sex individuals compete for limited resources. Additionally, females of some bird species exhibit snake-like hissing behaviour during incubation presumably to lower predation rates and improve fitness. Such behaviours may co-vary, forming a behavioural syndrome that could constrain trait expression. Here, we investigated a resident population of blue tits (Cyanistes caeruleus), to examine the repeatability and covariation of female–female aggression and hissing behaviour, aiming to determine if these constitute a behavioural syndrome. We quantified female–female aggression during simulated territorial intrusions and measured number of hissing calls in response to a simulated predator intrusion into the nest box. We found that both female–female aggression and hissing behaviour were repeatable traits, and that older females approached the intruder less. However, we found no evidence of covariation between female–female aggression and hissing behaviour. Thus, our findings suggest that female–female aggression and hissing behaviour, although both displayed in a nest defence context, are evolutionarily independent traits in the blue tit.

AbstractPreterm birth (PTB) is the leading cause of infant mortality globally. Research has focused on developing predictive models for PTB without prioritizing cost-effective interventions. Physical activity and sleep present unique opportunities for interventions in low- and middle-income populations (LMICs). However, objective measurement of physical activity and sleep remains challenging and self-reported metrics suffer from low-resolution and accuracy. In this study, we use physical activity data collected using a wearable device comprising over 181,944 h of data across N = 1083 patients. Using a new state-of-the art deep learning time-series classification architecture, we develop a ‘clock’ of healthy dynamics during pregnancy by using gestational age (GA) as a surrogate for progression of pregnancy. We also develop novel interpretability algorithms that integrate unsupervised clustering, model error analysis, feature attribution, and automated actigraphy analysis, allowing for model interpretation with respect to sleep, activity, and clinical variables. Our model performs significantly better than 7 other machine learning and AI methods for modeling the progression of pregnancy. We found that deviations from a normal ‘clock’ of physical activity and sleep changes during pregnancy are strongly associated with pregnancy outcomes. When our model underestimates GA, there are 0.52 fewer preterm births than expected (P = 1.01e − 67, permutation test) and when our model overestimates GA, there are 1.44 times (P = 2.82e − 39, permutation test) more preterm births than expected. Model error is negatively correlated with interdaily stability (P = 0.043, Spearman’s), indicating that our model assigns a more advanced GA when an individual’s daily rhythms are less precise. Supporting this, our model attributes higher importance to sleep periods in predicting higher-than-actual GA, relative to lower-than-actual GA (P = 1.01e − 21, Mann-Whitney U). Combining prediction and interpretability allows us to signal when activity behaviors alter the likelihood of preterm birth and advocates for the development of clinical decision support through passive monitoring and exercise habit and sleep recommendations, which can be easily implemented in LMICs.

Published: September 2023

AbstractIn this paper, a novel Resistive Random‐Access Memory (RRAM) read circuit has been designed and verified by simulation based on the RRAM model and parasitic capacitance of the circuit. Simulation results demonstrate the feasibility and effectiveness of the proposed circuit, with accurate reading of RRAM states and fast reading speed in the nanosecond range. The sense margin of the proposed circuit has improved as the array size increases, enhancing its application for advanced node RRAM array manufacture. Compared with conventional circuits, the proposed circuit achieved power consumption reduction of 6% and area reduction of 46.9 um2, resulting in a 97.5% reduction in area, providing an effective solution to address the cost and chip size challenges associated with RRAM industrialization.
Overview of ionosphere clutter suppression for high frequency surface wave radar (HFSWR) system: Observation, approaches, challenges and open issue
Authors: Ji Xiaowei , Wu Xiaochuan , Yang Qiang , Zhang Xin 
Published: September 2023

AbstractA great interest has been directed towards high frequency surface wave radar (HFSWR), because it is applied as long‐range early warning and real‐time measurements of sea surface condition tools in maritime surveillance. However, the unwanted reflection from the ionosphere (ionosphere clutter) damages the consistent detection performance of HFSWR. Target detection and environmental information extraction from radar echoes are primarily determined by the extent to which the medium contaminates the transmitted signals. Although the ionospheric signal corruption mechanisms are complex and various, a number of eliminating contamination approaches have been developed in the last 50 years. The purpose of this paper is providing an overview of the past and current clutter theoretical models and clutter suppression techniques for HFSWR system. The experimental results involved in the complex long‐term ionosphere observation and ionosphere echo analysis are first discussed. Special attention is paid to the correlation between the signal degradation sources and eliminating clutter techniques. Furthermore, the clutter suppression methods are classified based on the design idea. The specific clutter suppression methods as well as its operation principle are briefly introduced. Finally, several research trends and open issues are presented, with emphasis on the need for proactively controlling the radar design cost and generally agreed‐upon standards.

Aims. We aim to understand what drives the IRX–β dust attenuation relation at intermediate redshifts (0.5 < z < 0.8) in star-forming galaxies. We investigate the role of various galaxy properties in shaping this observed relation.
Methods. We used robust [O II]λ3727, [O III]λλ4959,5007, and Hβ line detections of our statistical sample of 1049 galaxies to estimate the gas-phase metallicities. We derived key physical properties that are necessary to study galaxy evolution, such as the stellar masses and the star formation rates, using the spectral energy distribution fitting tool CIGALE. Equivalently, we studied the effect of galaxy morphology (mainly the Sérsic index n and galaxy inclination) on the observed IRX–β scatter. We also investigated the role of the environment in shaping dust attenuation in our sample.
Results. We find a strong correlation with respect to the IRX–β relation on the gas-phase metallicity in our sample, as well as a strong correlation with galaxy compactness characterized by the Sérsic indexes. With higher metallicities, galaxies move along the track of the IRX–β relation towards higher IRX. Correlations are also seen with the stellar masses, specific star formation rates, and the stellar ages of our sources. Metallicity is strongly correlated with the IRX–β scatter, which also results from the presence of older stars and higher masses at higher beta values. Galaxies with higher metallicities show higher IRX and beta values. The correlation with specific dust mass strongly shifts the galaxies away from the IRX–β relation towards lower β values. We find that more compact galaxies go through a greater amount of attenuation than less compact galaxies. There is a subtle variation in the dust attenuation scatter between edge-on and face-on galaxies, but the difference is not statistically significant. Galaxy environments do not significantly affect dust attenuation in our sample of star-forming galaxies at intermediate redshift.

Context.Full-disc observations of the Sun in the Hαline provide information about the solar chromosphere, and in particular, about the filaments, which are dark and elongated features that lie along magnetic field polarity-inversion lines. This makes them important for studies of solar magnetism. Because full-disc Hαobservations have been performed at various sites since the second half of the 19th century, with regular photographic data having started at the beginning of the 20th century, they are an invaluable source of information on past solar magnetism.Aims.We derive accurate information about filaments from historical and modern full-disc Hαobservations.Methods.We consistently processed observations from 15 Hαarchives spanning 1909–2022. The analysed datasets include long-running ones such as those from Meudon and Kodaikanal, but also previously unexplored datasets such as those from Arcetri, Boulder, Larissa, and Upice. Our data processing includes photometric calibration of the data stored on photographic plates, the compensation for limb-darkening, and the orientation of the data to align solar north at the top of the images. We also constructed Carrington maps from the calibrated Hαimages.Results.We find that filament areas, similar to plage areas in Ca IIK data, are affected by the bandwidth of the observation. Thus, a cross calibration of the filament areas derived from different archives is needed. We produced a composite of filament areas from individual archives by scaling all of them to the Meudon series. Our composite butterfly diagram very distinctly shows the common features of filament evolution, that is, the poleward migration as well as a decrease in the mean latitude of filaments as the cycle progresses. We also find that during activity maxima, filaments cover ∼1% of the solar surface on average. The change in the amplitude of cycles in filament areas is weaker than in sunspot and plage areas.Conclusions.Analysis of Hαdata for archives with contemporaneous Ca IIK observations allowed us to identify and verify archive inconsistencies, which also have implications for reconstructions of past solar magnetism and irradiance from Ca IIK data.
Ectopic Spleen in the Pelvis: A Case Report
Authors: Algheryani Abdelhakim , Muftah Younis Sarah 
Published: September 2023

Ectopic spleen is a rare clinical condition characterized by splenic hypermobility caused by elongation or mal-development of the suspensory ligaments leading to the presence of spleen outside of its normal position. It is most commonly presented in children younger than 1 year and in females of childbearing age.A 34-year-old woman underwent magnetic resonance imaging (MRI) after suspicion of uterine fibroids. The patient only complained of a painless lower abdominal mass. MRI revealed the enlarged spleen in the pelvic area, measuring 17 × 4.6 cm, suspended by elongated, dilated, and tortuous pedicle in the absence of the spleen in its normal position. Multiple factors could be attributed to the development of an ectopic spleen. These include the following: (1) congenital anomalies in the development of the dorsal mesogastrium and the absence or malformation of the normal splenic suspensory ligaments, (2) acquired conditions such as splenomegaly and pregnancy. An ectopic spleen can present in a variety of ways clinically. It might pass unnoticed throughout life. However, ectopic spleen should be considered in the differential diagnosis of patients presented with an abdominal mass. Imaging modalities are used to make a final diagnosis. The treatment choice for an ectopic spleen is splenopexy. Splenectomy is only necessary in case of an infarction.
Can a Single Glomerulus Morphology Implicate Successful Therapy?
Authors: Ezwaie Mohamed O. , Elbarasi Sabah M. , Shawish Huda A. 
Published: September 2023

Recurrent gross hematuria of glomerular origin is frequently encountered in clinical practice, and in absence of specific serological marker, renal biopsy is mandatory to address the definitive diagnosis, and set out an appropriate therapeutic protocol. Technical deficiencies associated with practice of renal biopsy are frequently encountered, as inadequate number of glomeruli or poor immunofluorescence staining of kidney biopsy specimen; however, these deficiencies can be offset by detailed electron microscopy analysis of a single abnormal glom.We present a single middle-aged Libyan woman, with a rare glomerular disease, related to abnormal activation of alternative complement pathway, where renal biopsy report was initially not adequate and lacking immunohistochemistry workup. However, electron microscopy reports a characteristic abnormal glomerular deposit, coupled with clinical and biochemical data that guided our therapeutic protocol.In a middle-aged female who presented with recurrent gross hematuria and nephrotic range proteinuria, we should suspect a glomerular pathology. Further to immunoglobulin A nephropathy or lupus nephritis, particularly in presence of complement abnormalities and negative serology for glomerulopathy-related autoantibodies, dense deposit disease and C3 glomerulonephritis that are rare complement mediated glomerulopathy should be considered as a seronegative lupus nephritis-equivalent, in terms of their membranoproliferative features on light microscopy, and when setting out appropriate therapeutic protocol. Patient and family counseling for C3 glomerulopathy is essential because this type of glomerulopathy has a recurrence rate after kidney transplant.

Abstract
Objectives This article (1) develops a Fast Healthcare Interoperability Resources app, Health Dart, that integrates information from Indiana's community health information exchange (HIE), the Indiana Network for Patient Care (INPC), directly with Cerner, an electronic health record (EHR), and (2) evaluates the effect of Health Dart's implementation on HIE use.
Methods Health Dart was implemented in 14 Indiana University Health emergency departments (EDs) using a stepped-wedge study design. We analyzed rates of INPC use in 286,175 ED encounters between October 1, 2019 and December 31, 2020. Logistic regression was used to model the probability of INPC use given the implementation context, such as user interface (UI) enhancements and the coronavirus disease 2019 pandemic.
Results INPC use increased by 131% across all encounters (from 3.6 to 8.3%; p < 0.001) after Health Dart implementation. INPC use increased by 144% (from 3.6 to 8.8%; p < 0.001) more than 2 months postimplementation. After UI enhancements, postimplementation INPC use increased by 123% (from 3.5 to 7.8%) compared to 181% (from 3.6 to 10.1%; p < 0.001) in postimplementation encounters that occurred before UI enhancements. During the pandemic, postimplementation INPC use increased by 135% (from 3.4 to 8.0%; p < 0.001) compared to 178% (from 3.6 to 10%; p < 0.001) in postimplementation encounters that occurred before the pandemic. Statistical significance was determined using 95% confidence intervals (α = 0.05).
Conclusion Direct integration of HIE information into an EHR substantially increased frequency of HIE use, but the effect was weakened by the UI enhancements and pandemic. HIE information integrated into EHRs in the form of problem-oriented dashboards can potentially make information retrieval more efficient and effective for clinicians.
Exploring place branding in the Global South: the case of Johannesburg, South Africa
Authors: Mbinza Zenzile 
Published: September 2023

AbstractThis paper presents two points of discussion. Firstly, the paper contends that through the efforts made by the city of Johannesburg (CoJ, the council) in branding, there is scope to explore cities in the Global South from other perspectives other than the popular obsessions of poverty, informality and violence that currently litter literature on exploring urban issues in these settings especially amongst scholars in the developed world. Secondly, it argues that the CoJ, through its consecutive place brands, has complicated its relationship with different stakeholders including residents and businesses. This is because in comparison to other cities in South Africa and in Africa more generally, the city of Johannesburg has managed to develop strong, recognisable place brands over time. While this is lauded, it leaves room to ruminate about the necessity of place branding in a city that is encumbered by huge socio-economic divides.
The impact of country of origin on consumer purchase decision of luxury vs. fast fashion: case of Saudi female consumers
Authors: Abalkhail Tagreed Saleh 
Published: September 2023

AbstractThe purpose of this paper is to examine the impact of country of origin on purchase decisions of luxury and fast fashion. The countries of origin include the US and European countries like France, Italy, UK, Spain, Germany, and Sweden. Moreover, conspicuous consumption was included in this research as a mediating variable, and brands from the US and Europe were evaluated. A total of 443 women were surveyed. The data were assessed using a structural equation model and a t-test. The results confirm the positive relationship between the country of origin and purchase decision of luxury and fast fashion; conspicuous consumption acted as a mediating variable that affected this relation. The results also confirm the positive relationship between conspicuous consumption and consumer purchase decisions of luxury and fast fashion brands. No difference was found between luxury and fast fashion in terms of the relation to the country of origin and conspicuous consumption. Moreover, US brands were evaluated higher than European ones for both luxury and fast fashion. This study gives insight into the role of country of origin in purchase decisions. In addition, it provides a deep understanding of the term of conspicuous consumption and its relation not only to luxury but also to fast fashion.
Industrial policy environments and the flourishing of African multinational enterprises
Authors: Zoogah Baniyelme D. , Degbey William Y. , Elo Maria 
Published: September 2023

AbstractResearch on African organizations has focused on the influence of environmental factors in organizational effectiveness. However, increasing concerns about challenges in Africa and how they negatively affect organizational outcomes have necessitated leveraging the “positive turn” of organizational scholarship to advance a perspective of how industrial policies can permit Africa-originated multinational enterprises (A-MNEs) to flourish. We propose a multilevel model in which the industrial policy environment comprised of agency and policy development positively impacts A-MNE flourishing, a composite index of human, environmental, and economic flourishing. This relationship is mediated by industrial policies – labor, trade, infrastructure, and resources – and moderated by policy fit, relevance, and timeliness. Overall, we shift the old paradigm of organizational outcomes represented by organizational effectiveness to a new paradigm represented by organizational flourishing. This new paradigm seems more appropriate for Africa, which is bedeviled by unusual challenges that limit effectiveness. We discuss empirical testing of the model and implications for managers.
Finding common ground in uncertain times: assessing the prospect of multilateralism in transatlantic climate change policy
Authors: Wiedekind Jakob , Lemke Christiane 
Published: September 2023

AbstractClimate change policy stands out as a highly salient issue in European and in American public opinion. This article contends that a significant transatlantic consensus supports multilateral action on climate change. Leveraging a broad review of survey data in our time series, the analysis identifies a clear pattern of increasing agreement in public opinion. Yet progress in joint transatlantic climate change action has been rather slow and fragmented. To explain this puzzle, we connect these findings to pitfalls for transatlantic cooperation by weighing partisan polarization and regional differences in the U.S. and country variations in the EU as plausible hurdles to policy consistency. We argue that, beneath broader trends in shared concerns, roadblocks on the national level inhibit the implementation of coherent and effective transatlantic climate change policies.
