Published: October 2024

AbstractSome training paradigms can improve performance specific to the trained portion of the visual field. Similarly, experience with both pathological and simulated central vision loss can result in compensatory improvement in performance specific to a spared retinal location. The mechanisms underlying these improvements are still debated. Modifications in the capacity to allocate attention to trained locations might explain some of the changes in performance after learning, especially given similarities between behavioral improvements due to training and improvements due to changes in attention. Using a gaze-contingent simulated scotoma paradigm which simulates central vision loss, we tested whether training to use peripheral vision influenced three aspects of visual attention: habitual attention, dynamic exogenous attention, and dynamic endogenous attention. After training, performance improvements were consistent with increased habitual attention to the trained location. Conversely, measures of dynamic shifts of attention (exogenous and endogenous attention) improved similarly in both trained and untrained locations. The lack of retinotopic specificity in dynamic attention improvements suggests that retinotopically specific perceptual improvements following simulated central vision loss are not mediated by dynamic attention changes. On the other hand, habitual attention did change retinotopically, leaving the possibility open that this aspect of attention may drive some retinotopically specific training effects. This work constrains the range of mechanisms that could underlie performance improvements after peripheral vision training, suggesting that habitual attention and dynamic attention are affected independently.

Abstract
Secondary bunch rots caused by Aspergillus species belonging to the section Nigri, commonly called black aspergilli, pose a serious threat to grapes yield and quality. Due to their ability to produce ochratoxin A (OTA), they are considered the primary source of contamination of this mycotoxin in grapes. In this study, a three-year survey was realized to assess the occurrence of black aspergilli in grapes harvested in the Umbria region, a very important grapevine cultivation area in central Italy, by fungal isolation and phylogenetic analysis. In addition, the influence of growing season, vineyard location, farming system and grapes growth stages on black aspergilli distribution was examined. Phylogenetic analysis of the 208 obtained isolates showed the presence of three black aspergilli species: Aspergillus tubingensis, Aspergillus welwitschiae and Aspergillus uvarum. Interestingly, A. carbonarius, one of the most important OTA producers, was not detected in the surveyed years. A. tubingensis, whose ability to produce OTA is controversial, was always the most isolated species followed by A. welwistichiae (OTA producer). The species A. uvarum (unable to produce OTA) was detected only in one surveyed year with a low incidence. A. tubingensis was always the species with the highest incidence, regardless of location, and farming system. Growth stage appeared to influence the incidence of the three species, that, in the case of A tubingensis, was lower during setting in comparison to berries pea-size and berries harvest-ripe. Finally, in the setting and berries pea-size stages, a stereomicroscope analysis, showed that flower debris was the substrate from which black aspergilli mainly developed prior to colonizing berries and bunches.
Governance, institutional quality and economic complexity in selected African countries

Published: October 2024

Abstract
New economic thinking speculates that the diversification and sophistication of economic capabilities/structures is key in explaining why African countries lag in development behind the rest of the world. We question the extent to which non-traditional growth factors such as governance and institutional quality are related to economic complexity for 35 African countries. We estimate panel GMM regressions using 8 different measures of governance/institutional quality for both linear and kinked regressions using annual data collected between 1996 and 2021. The baseline estimates reveal a positive linear relationship between most measures of governance and institutional quality and economic complexity. Our sensitivity analysis further show that institutions/governance have stronger relationship with economic complexity in the post-global financial crisis era. Moreover, nonlinear or kinked relationships emerge once the data is segregated into different income and resource abundant groups. Altogether, our findings of a nonlinear relationship between institutions/governance and economic complexity are novel to the literature and offer unique insights on how African policymakers can use governance/institutions for improving the complexity of production processes.

AbstractThe engineering of biochars with desired morphologies and pore structures is a far-reaching objective towards sustainable pore-dependent environmental technologies, such as water and soil remediation or catalysis. We hereby report a series of experiments that allow the direct following of the shape and porosity of single biochar particles during pyrolysis. Particles ~ 1–2 mm in diameter of unwashed and water-washed raw walnut shells were continuously 3D imaged during pyrolysis to 575 ℃ at a 10 K min−1 in Ar to obtain time- and temperature-resolved x-ray micro computed tomographies to a 0.82 μm resolution. Results showed visual evidence of a 30% and 70% v/v particle shrinkage for unwashed and washed samples, respectively. Particle swelling between 200 and 300 ℃ in the unwashed sample provided evidence of the softening of native biopolymers associated with lignin in untreated biomass. A purpose-defined parameter Λ shows the temperature-dependence of pore re-distribution towards the center of the particle to be linear for both samples. Λ was found to be $$3.2\times {10}^{-4}{K}^{-1}$$

in the washed sample, approximately 3.5 times faster than in the unwashed one. Such linear dependence is significantly slower than an exponential Arrhenius-like trend thereby providing a qualitative measure of the heat and mass transport phenomena limiting the chemical reactions in the porous medium. This evidence is key to resolving the pathways to the thermochemical decomposition of biomass leading to preparation of precision-engineered biochars.

Addressing ethical challenges in automated vehicles: bridging the gap with hybrid AI and augmented utilitarianism
Authors: Gros Chloe , Kester Leon , Martens Marieke , Werkhoven Peter 
Published: October 2024

AbstractIn the realm of automated vehicles (AVs), the focus is predominantly on the potential of sub-symbolic deep-learning-based artificial intelligence (AI) systems. Our study questions the suitability of this data-driven approach for AVs, particularly in embodying societal values in their behaviour. Through a systematic examination of sub-symbolic and symbolic AI, we identify key issues for AVs, including adaptability, safety, reliability, trust, fairness, transparency, and control. Deep learning systems’ lack of adaptability and inherent complexities pose significant safety concerns and hinder meaningful human control. This limitation prevents humans from effectively updating AI decision-making processes to better reflect ethical values. Furthermore, deep learning systems are prone to biases and unfairness, leading to incidents that are difficult to explain and rectify. In contrast, symbolic, model-based approaches offer a structured framework for encoding ethical goals and principles within AV systems, thus enabling meaningful human control. However, they also face challenges, such as inefficiencies in handling large amounts of unstructured data for low-level tasks and maintaining explicit knowledge bases. Therefore, we advocate for hybrid AI, combining symbolic and sub-symbolic models with symbolic goal functions. We propose Augmented Utilitarianism (AU) as an ethical framework for developing these goal functions, aiming to minimise harm by integrating principles from consequentialism, deontology, and virtue ethics, while incorporating the perspective of the experiencer. Our methodology for eliciting moral attributes to construct an explicit ethical goal function engages collective societal values through iterative refinement, contributing to the development of safer, more reliable, and ethically aligned automated driving systems.
Tail risk driven by investment losses and exogenous shocks
Authors: Man Xinyue , Tang Qihe 
Published: October 2024

AbstractConsider a company whose business carries the potential for investment losses and is additionally vulnerable to exogenous shocks. The unpredictability of the shocks makes it challenging for both the company and the regulator to accurately assess their impact, potentially leading to an underestimation of solvency capital when employing traditional approaches. In this paper, we utilize a stylized model to conduct an extreme value analysis of the tail risk of the company under a Fréchet-type and a Gumbel-type shock. Our main results explicitly demonstrate the different roles of investment risk and shock risk in driving large losses. Furthermore, we derive asymptotic estimates for the value at risk and expected shortfall of the total loss. Numerical studies are conducted to examine the accuracy of the obtained estimates.
Central Banks as Regulators and (also) Operators of Instant Payments Schemes: Confronting the Criticisms of “Needless Intervention” and “Unfair Competition”
Authors: Ragazzo Carlos , Caminha Lucas 
Published: October 2024

Abstract
We argue it is efficient/desirable for central banks to operate retail Instant Payments (IP) schemes and infrastructure, considering that (i) payment service providers (PSPs) face a problem of collective action, which limits their capacity to deliver a cheap, fast, open-architecture and interoperable IP scheme; and (ii) this problem may be overcome by a central bank (economically neutral actor) with a dual role of regulator and operator of IP schemes, especially by mandating participation of large PSPs and ensuring that the low cost of infrastructure is passed on to consumers. We corroborate with data from Brazil’s Pix and India’s UPI, where the efficiencies of central bank-led IP schemes also led to social gains through financial inclusion.
Geometric properties of disintegration of measures
Authors: POSSOBON RENATA , RODRIGUES CHRISTIAN S. 
Published: October 2024

Abstract
In this paper, we study a connection between disintegration of measures and geometric properties of probability spaces. We prove a disintegration theorem, addressing disintegration from the perspective of an optimal transport problem. We look at the disintegration of transport plans, which are used to define and study disintegration maps. Using these objects, we study the regularity and absolute continuity of disintegration of measures. In particular, we exhibit conditions for which the disintegration map is weakly continuous and one can obtain a path of measures given by this map. We show a rigidity condition for the disintegration of measures to be given into absolutely continuous measures.

Abstract
Hypertension and depression are increasingly common noncommunicable diseases in Ghana and worldwide, yet both are poorly controlled. We sought to understand how healthcare workers in rural Ghana conceptualize the interaction between hypertension and depression, and how care for these two conditions might best be integrated. We conducted a qualitative descriptive study involving in-depth interviews with 34 healthcare workers in the Kassena-Nankana districts of the Upper East Region of Ghana. We used conventional content analysis to systematically review interview transcripts, code the data content and analyze codes for salient themes. Respondents detailed three discrete conceptual models. Most emphasized depression as causing hypertension: through both emotional distress and unhealthy behavior. Others posited a bidirectional relationship, where cardiovascular morbidity worsened mood, or described a single set of underlying causes for both conditions. Nearly all proposed health interventions targeted their favored root cause of these disorders. In this representative rural Ghanaian community, healthcare workers widely agreed that cardiovascular disease and mental illness are physiologically linked and warrant an integrated care response, but held diverse views regarding precisely how and why. There was widespread support for a single primary care intervention to treat both conditions through counseling and medication.
The Massacre of Corpus Thursday: A Historical Approach Through Images
Authors: del Castillo Troncoso Alberto 
Published: October 2024

AbstractThis article examines one of the most violent episodes in Mexico’s recent history—the Corpus Thursday massacre orchestrated by the Mexican government against young students on June 10, 1971. The event marked the beginning of a period known as the guerra sucia (dirty war), marked by the systematic repression of students and dissenting political groups by government forces. The present work advocates for “making history with photographs,” urging readers to explore the historical moment through the narratives presented by three distinct historical actors: the press, independent photographers, and the perspective of power from governmental organizations.
Erythrocyte membrane and breast milk fatty acid profile in lactating mothers: relationship with infant erythrocyte membrane fatty acid profile

Published: October 2024

AbstractDuring the first thousand days of life, fetus and infant’s nutrition depends on mother’s diet. Polyunsaturated fatty acids (PUFA) are important substrates in infant neurogenesis. We related erythrocyte membrane (EM) and breast milk fatty acids (FA) profile in lactating mothers with the EM FA profile in exclusively breastfed infants and evaluated maternal fat consumption. We conducted an observational, cross-sectional analytical study. During the 2016–2019 period, milk and blood samples from adult mothers 90 days post-partum and infant’s blood were analysed, and FA were determined by GC. A frequency of consumption survey of fatty acids precursor foods and sources was conducted. The sample included forty-five mother–infant EM and forty-five milk samples donated by the same mothers. A low percentage of DHA (0·14 (0·12–0·2)) was found in milk, consistent with mother’s low consumption of DHA-rich foods. A significant positive correlation between infant’s EM DHA percentage and milk DHA percentage (r = 0·39; P value 0·008), as well as between infant’s EM ω-3 fatty acids sum and milk DHA percentage (r = 0·39; P value 0·008), was found. When milk had a DHA percentage greater than or equal to 0·20 %, infants had a significant increase in DHA in their EM. Mother’s consumption of DHA precursors and sources was NS. The relation between the DHA percentage distribution found in maternal milk, and the DHA percentage distribution found in infant’s and mother’s EM was proven in this population. Dietary fatty acid intake is associated with the maternal milk lipid distribution and with mothers’ and infant’s EM fatty acids percentage.

RésuméGilles Deleuze est, parmi les penseurs français contemporains, celui ayant démontré la plus grande sensibilité à l’égard de la culture québécoise en intégrant quelques-unes de ses forces révolutionnaires dans son œuvre. C'est ce qu'illustre la première partie de l'article en faisant référence à des figures culturelles marquantes discutées par Deleuze : Jack Kérouac, Pierre Perrault, Michèle Lalonde, Norman McLaren et Alexis le Trotteur. L'article explore ensuite la réception de Deleuze au Québec dans et à l'extérieur des milieux universitaires en montrant que la pensée deleuzienne a pris part à la contre-culture avant d'acquérir une visibilité au sein des départements de philosophie.
“A Not Unworthy Record”?: Sir Ponnambalam Arunachalam's 1901 Census of Ceylon and the Transforming of Dynamic Nominalism
Authors: Schubert Andi 
Published: October 2024

AbstractDrawing inspiration from Ian Hacking's claim that new modes of description generate new possibilities for action, this essay explores the impact of changes to the mode of description through the 1901 Census in Ceylon. It begins by exploring the modes of description used in the censuses prior to 1901 to demonstrate that in Ceylon, the census was yet to emerge as the critical tool of colonial governance claimed by dominant scholarship around colonial census taking. This leads to an exploration of how the changes that Sir Ponnambalam Arunachalam, the first Ceylonese Census superintendent, made to the Census Ordinance, Census Manual, and Census Report impacted the function of the census as a mode of description. It then explores the possibilities for action generated by these changes in the mode of description, paying particular attention to the ways in which the census shaped elite, indigenous activism leading to the first major reforms of the colonial governance structure in Ceylon, including the introduction of limited franchise. Thus, Ceylon's 1901 Census affords a unique opportunity to examine the impact that shifts in modes of description have on possibilities for action.
Role of BT shunt in tetralogy of Fallot
Authors: Rasool Faiz , Qureshi Amna Zafer , Khan Asim , Kazmi Tehmina , Shah Salman Ahmad 
Published: October 2024

AbstractIntroduction:Modified Blalock-Taussig shunt (BT shunt) is a palliative operation used for cyanotic heart diseases with decreased pulmonary blood supply. The definitive management of tetralogy of Fallot (TOF) is total corrective surgery, but these patients can be palliated with BT shunt. In the modern world, the BT shunt is getting out of favour in patients with TOF. In this article, we will share our 5-year experience at our institute, which also shows a decreasing trend.Patients and methods:It is a retrospective study. Files of all the patients admitted in our department from January 2019 to December 2023 were reviewed. Age, weight, hospital stay, inotropic support duration, mechanical ventilation duration, and outcomes were studied.Results:From January 2019 to December 2023, 173 patients underwent BT shunt for TOF. The mean age was 31 months, and the mean weight was 9.3 kg. The overall mortality for BT shunt was 15% after BT shunt. Hypercyanotic spell not controlled by medical management was the most common indication for BT shunt in our setup. Most of the patients with hypercyanotic spells were also candidates for total correction but due to the emergency, BT shunt was performed.Conclusion:The role of BT shunt in patients with TOF is decreasing due to PDA/RVOT stenting, it is likely that the BT shunt in TOF will become a thing of the past in the future even in developing countries like ours.
Bias‐Eliminating Techniques in the Computation of Power Spectra for Characterizing Gravity Waves: Interleaved Methods and Error Analyses
Authors: Jandreau Jackson , Chu Xinzhao 
Published: October 2024

AbstractObservational data inherently contain noise which manifests as uncertainties in the measured parameters and creates positive biases or noise floors in second‐order products like variances, fluxes, and spectra. Historical methods estimate and subsequently subtract noise floors, but struggle with accuracy. Gardner and Chu (2020, doi.org/10.1364/AO.400375) proposed an interleaved data processing method, which inherently eliminates biases from variances and fluxes, and suggested that the method could also eliminate noise floors of power spectra. We investigate the interleaved method for spectral analysis of atmospheric waves through theoretical studies, forward modeling, and demonstration with lidar data. Our work shows that calculating the cross‐power spectral density (CPSD) from two interleaved subsamples does reduce the spectral noise floor significantly. However, only the Co‐PSD (the real part of CPSD) eliminates the noise floor completely, while taking the absolute magnitude of CPSD adds a reduced noise floor back to the spectrum when the sample number is finite. This reduced noise floor can be further minimized through averaging over more observations, completely different from traditional spectrum calculations whose noise floor cannot be reduced by incorporating more samples. We demonstrate the first application of the interleaved method to spectral data, successfully eliminating the noise floor using the Co‐PSD in a forward model and in lidar observations of the vertical wavenumber of gravity waves at McMurdo, Antarctica. This high accuracy is gained by sacrificing precision due to photon‐count splitting, requiring additional observations to counter this effect. We provide quantitative assessment of accuracy and precision as well as application recommendations.
Predicting the Probability of Abrupt Changes to Wave‐Generated Seafloor Sand Ripples
Authors: Penko A. M. , Kearney W. S. 
Published: October 2024

AbstractA new, non‐dimensional ripple reset parameter and a stochastic point process model is used to estimate the likelihood of propagating ocean waves to form ripples on sandy seabeds. The ripple reset parameter is a function only of water depth, significant wave height, and mean grain size. Ripple formation is estimated by the magnitude of an intensity function based on a time series of the ripple reset parameter. The point process model is trained with a time series of observed waves and ripple change, and is then applied to predict the probability that a ripple field with a different geometry will form within a given time interval from another time series of wave data. The model is trained and tested with four field deployments at three field sites to determine its skill in predicting the ripple formation (a) at one field site over one time period after being trained with observations from the same site over a different time period, and (b) at one field site after being trained with observations from another field site. Results show that while the model is sufficient at predicting ripple formation in both scenarios, it is sensitive to the quality and quantity of the training data. Increasing the amount of training data greatly improves model performance. Employing a stochastic model based on a simple ripple reset parameter reduces tunable model parameters and provides a prediction of the probability for ripple formation given only a water depth, grain size, and time series of wave heights.
