Published: May 2024

AbstractPower bed fusion of metals using a laser beam (PBF-LB/M) offers unique possibilities to manufacture functionally graded materials (FGM) consisting of different alloys. These so-called multi-material parts enable their material properties to be tailored to local material requirements. In this paper, a new methodical approach for the production of metal FGM with transition zones oriented in different directions and manufacturing sequences of the different materials is investigated. Existing approaches for the manufacturing of these transition zones were enhanced with graded parameter variations, spatial laser movement modulation techniques (wobbling), and geometric approximations using a step structure. For the validation of the approach and the characterization of the transition zones, the manufactured samples were investigated and characterized using optical microscopy and hardness profile measurements. Furthermore, the density of the transition zones was analyzed by image data processing. The feasibility of the presented methods is shown and the production of defect-free transition zones with controlled expansions for functionally graded materials via PBF-LB/M achieved
A model-based boosting approach to risk factors for physical intimate partner violence against women and girls in Mexico
Authors: Torres Munguía Juan Armando 
Published: May 2024

AbstractThe goal of this study was to identify and describe the extent to which a comprehensive set of risk factors from the ecological model are associated with physical intimate partner violence (IPV) victimization in Mexico. To achieve this goal, a structured additive probit model is applied to a dataset of 35,000 observations and 42 theoretical correlates from 10 data sources. Due to the model's high dimensionality, the boosting algorithm is used for estimating and simultaneously performing variable selection and model choice. The findings indicate that age at sexual initiation and marriage, sexual and professional autonomy, social connectedness, household overcrowding, housework division, women's political participation, and geographical space are associated with physical IPV. The findings provide evidence of risk factors that were previously unknown in Mexico or were solely based on theoretical grounds without empirical testing. Specifically, this paper makes three key contributions. First, by examining the individual and relationship levels, it was possible to identify high-risk population subgroups that are often overlooked, such as women who experienced sexual initiation during childhood and women living in overcrowded families. Second, the inclusion of community factors enabled the identification of the importance of promoting women's political participation. Finally, the introduction of several emerging indicators allowed to examine the experiences faced by women in various aspects of life, such as decision-making power, social networks, and the division of housework.

Published: May 2024

AbstractThe speech multi-feature MMN (Mismatch Negativity) offers a means to explore the neurocognitive background of the processing of multiple speech features in a short time, by capturing the time-locked electrophysiological activity of the brain known as event-related brain potentials (ERPs). Originating from Näätänen et al. (Clin Neurophysiol 115:140–144, 2004) pioneering work, this paradigm introduces several infrequent deviant stimuli alongside standard ones, each differing in various speech features. In this study, we aimed to refine the multi-feature MMN paradigm used previously to encompass both segmental and suprasegmental (prosodic) features of speech. In the experiment, a two-syllable long pseudoword was presented as a standard, and the deviant stimuli included alterations in consonants (deviation by place or place and mode of articulation), vowels (deviation by place or mode of articulation), and stress pattern in the first syllable of the pseudoword. Results indicated the emergence of MMN components across all segmental and prosodic contrasts, with the expected fronto-central amplitude distribution. Subsequent analyses revealed subtle differences in MMN responses to the deviants, suggesting varying sensitivity to phonetic contrasts. Furthermore, individual differences in MMN amplitudes were noted, partially attributable to participants’ musical and language backgrounds. These findings underscore the utility of the multi-feature MMN paradigm for rapid and efficient investigation of the neurocognitive mechanisms underlying speech processing. Moreover, the paradigm demonstrated the potential to be used in further research to study the speech processing abilities in various populations.
Quality of Life and its sociodemographic determinants: a population-based study from rural Punjab, India
Authors: Kasaudhan Sapana , Saraswathy Kallur Nava , Chaudhary Vineet 
Published: May 2024

Abstract
Background
Quality of Life (QoL) is an individual’s subjective perception of well-being within their cultural context. While most QoL studies focus on individuals with certain health conditions, factors such as sex, marital status, education, and family structure can influence QoL beyond age and health conditions. Considering the limited studies on QoL in the general Indian population, especially from rural areas, the present study aims to explore the QoL and sociodemographic factors affecting QoL among community-dwelling adults in rural Punjab.

Methods
This community-based cross-sectional study was conducted among 931 individuals of both sexes (59.6% female) aged 20–75 years residing in rural areas of Mansa, Punjab, India. Sociodemographic data were collected using an interview schedule, and QoL was measured using the WHOQOL-BREF.

Results
The overall mean QoL score was found to be 67.44 ± 14.7. The most affected QoL was in the physical domain (mean = 60.203 ± 13.49), followed by psychological (mean = 65.67 ± 18.3), social-relationship (mean = 69.88 ± 26.43), and environmental domains (mean = 74.05 ± 20.58). Adjusted logistic regression analysis revealed female sex, advanced age (age group ≥ 60 years), illiteracy, and unmarried status to be positively associated and family size of 6–10 members to be negatively associated with poor QoL.

Conclusion
The study suggests that females, elderlies, illiterates, and unmarried individuals may be at a higher risk of poor QoL. Further, education and a bigger family size appear to increase subjective well-being among participants.

Abstract
Background
This scoping review aimed to characterise near-death experiences in the setting of cardiac arrest, a phenomenon that is poorly understood and may have clinical consequences.

Method
PubMed/MEDLINE was searched to 23 July 2023 for prospective studies describing near-death experiences in cardiac arrest. PRISMA-ScR guidelines were adhered to. Qualitative and quantitative data were synthesised. Meta-analysis was precluded due to data heterogeneity.

Results
60 records were identified, of which 11 studies involving interviews were included from various countries. Sample size ranged from 28–344, and proportion of female patients (when reported) was 0–50%, with mean age (when reported) ranging 54–64 years. Comorbidities and reasons for cardiac arrest were heterogeneously reported. Incidence of near-death experiences in the included studies varied from 6.3% to 39.3%; with variation between in-hospital (6.3–39.3%) versus out-of-hospital (18.9–21.2%) cardiac arrest. Individual variables regarding patient characteristics demonstrated statistically significant association with propensity for near-death experiences. Reported content of near-death experiences tended to reflect the language of the questionnaires used, rather than the true language used by individual study participants. Three studies conducted follow-up, and all suggested a positive life attitude change, however one found significantly higher 30-day all-cause mortality in patients with near-death experiences versus those without, in non-controlled analysis.

Conclusions
From prospective studies that have investigated the phenomenon, near-death experiences may occur in as frequent as over one-third of patients with cardiac arrest. Lasting effects may follow these events, however these could also be confounded by clinical characteristics.
China’s privacy protection strategy and its geopolitical implications
Authors: Zhang Chi 
Published: May 2024

AbstractHow has China’s privacy protection strategy been developed, with its broad scope and stringent requirements for data localization and cross-border data flows? What are the broader geopolitical implications of its divergence from Western models of data privacy? This paper argues that China's privacy protection strategy, characterized by its comprehensive regulatory framework and government access to data, is redefining the contours of global data governance and creating new geopolitical fault lines. Drawing on official documents, laws, regulations, and a case study, this paper highlights the evolution of the regulatory framework in response to emerging challenges posed by technological innovations and the wider geopolitical environment. This paper contributes to the broader discussion regarding the implications of China's privacy protection approach, highlighting potential normative clashes with countries that favor a more open digital economy. China's efforts in developing its own privacy protection strategy have also resulted in the formulation of global standards for data privacy.
A pilot survey on knowledge, attitudes, and practices of smallholder dairy owners towards the importance of colostrum feeding to newborn calf in Humbo District of Wolaita Zone, Southern Ethiopia
Authors: Gebremeskel Haben Fesseha , Mesfin Henok , Kebede Isayas Asefa 
Published: May 2024

Abstract
Background
Colostrum is the secretion produced by the mammary gland of mammals and it is passively transferred immunity that protects neonates from infectious diseases.

Methods
A cross-sectional study was conducted from December 2021 to June 2022 to assess the community’s knowledge, attitude, and practice of smallholder dairy owners towards the importance of colostrum feeding to newborn calves in Humbo districts. A structured questionnaire was provided for 400 randomly selected smallholder dairy owners for face-to-face interviews.

Results
The results showed that females (21.6%), college and university levels (20.2%), farmers (15.4%), and single individuals (17.6%) had better knowledge compared to the respective status of respondents on colostrum feeding practices. Also, there was an association between sex, occupation, marital status, and knowledge of colostrum-feeding practices. Similarly, 32.5% of respondents with an elementary background practice the separation of calves from the dam soon after birth to prevent transmission of infection. There was an association between the educational background of the respondents and the perception of the respondents regarding colostrum feeding to newborn calves. Nearly, 30% of respondents had an elementary education background waiting for their calf to get up on its own and suckle from their dam. Likewise, 26.1%, 31.5%, and 23.8% of illiterate, elementary, college, and university graduate respondents, respectively, provide calves with 10 to 12% of their birth weight as colostrum within the first 8 h of calf’s life. Besides, the majority of the respondents (27.5%) believed that colostrum was the best food for calves’ growth, and the level of circulating antibodies in the calf's blood has a direct influence on its disease resistance.

Conclusion
The study revealed that smallholder dairy owners have different perceptions concerning knowledge, practice, and attitude on the importance and time of feeding colostrum to neonates during the early life of postpartum. Thus, awareness creation and training programs should be provided for smallholder dairy farmers as well as the use of colostrum feeding, and its role in the prevention of neonatal and preweaning calf mortality and morbidity.
Dynamic feature-based deep reinforcement learning for flow control of circular cylinder with sparse surface pressure sensing
Authors: Wang Qiulei , Yan Lei , Hu Gang , Chen Wenli , Rabault Jean , Noack Bernd R. 
Published: May 2024

This study proposes a self-learning algorithm for closed-loop cylinder wake control targeting lower drag and lower lift fluctuations with the additional challenge of sparse sensor information, taking deep reinforcement learning (DRL) as the starting point. The DRL performance is significantly improved by lifting the sensor signals to dynamic features (DFs), which predict future flow states. The resulting DF-based DRL (DF-DRL) automatically learns a feedback control in the plant without a dynamic model. Results show that the drag coefficient of the DF-DRL model is 25 % less than the vanilla model based on direct sensor feedback. More importantly, using only one surface pressure sensor, DF-DRL can reduce the drag coefficient to a state-of-the-art performance of approximately 8 % at Reynolds number

$(Re) = 100$

and significantly mitigates lift coefficient fluctuations. Hence, DF-DRL allows the deployment of sparse sensing of the flow without degrading the control performance. This method also exhibits strong robustness in flow control under more complex flow scenarios, reducing the drag coefficient by 32.2 % and 46.55 % at

$Re =500$

and 1000, respectively. Additionally, the drag coefficient decreases by 28.6 % in a three-dimensional turbulent flow at

$Re =10\,000$

. Since surface pressure information is more straightforward to measure in realistic scenarios than flow velocity information, this study provides a valuable reference for experimentally designing the active flow control of a circular cylinder based on wall pressure signals, which is an essential step toward further developing intelligent control in a realistic multi-input multi-output system.
Effect of age of first exposure on L2 contextual lexical semantic learning: an ERP investigation
Authors: Xu Shuang , Wang Hailing , Li Shouxin , Ouyang Guang 
Published: May 2024

AbstractAge of first exposure (AoFE) is an important factor that influences the quality of L2 acquisition. This study aims to investigate the AoFE effect on the contextual learning of L2 novel words at the neural level, as measured by the N400 component from event-related potentials (ERPs). Eighty-eight participants were recruited for the experiment of L2 pseudoword learning, which includes a learning session and a testing session. The participants’ EEG data were recorded from the testing session, and the N400 effect was derived from target words that were either congruous or incongruous with the context. The linear mixed model and multiple regression model revealed a positive AoFE effect on the N400 effect in discourses that were designed for testing retrieval of episodic and semantic memory even after accounting for the variance contributed by several confounding factors. In addition to AoFE, the effects of total L2 exposure, L2 proficiency and personality on the L2 novel word learning performance indicated by the N400 effect were also confirmed in the statistical results.

Published: May 2024

AbstractThis cross-sectional study employs structural equation modelling (sEM) to explore both direct and indirect effects of parental level of education and child individual factors on the length-for-age outcomes in children aged 6–24 months assisted by the Bolsa Família Program in the State of Alagoas. A total of 1448 children were analysed by the sEM technique. A negative standardised direct effect (sDE) of the children’s younger age (sDE: −0·06; P = 0·017), the use of bottle feeding (sDE: −0·11; P < 0·001) and lack of a minimum acceptable diet (sDE: −0·09; P < 0·001) on the length-for-age indicator was found. Being female (SDE: 0·08; P = 0·001), a higher birth weight (SDE: 0·33; P < 0·001), being ever breastfed (sdE: 0·07; P = 0·004) and a higher level of parental education (SDE: 0·09; P < 0·001) showed a positive SDE effect on the child’s length-for-age. The model also demonstrated a negative standardised indirect effect (SIE) of the sweet beverage consumption (SIE: −0·08; P = 0·003) and a positive effect of being ever breastfed (SIE: 0·06; P = 0·017) on the child’s length-for-age through parental level of education as a mediator. This research underscores the crucial role of proper feeding practices and provides valuable insights for the development of targeted interventions, policies and programmes to improve nutritional well-being and promote adequate linear growth and development among young children facing similar challenges.

Published: May 2024

AbstractAptrootia khaoyaiensis Polyiam & Lücking is described as new to science from dry dipterocarp forest in central Thailand, based on morphological assessment and sequence data of the mitochondrial small subunit (mtSSU). The new species is characterized by a corticolous habit, a corticate thallus, ascomata typically immersed in the thallus, with a brown to blackish ostiolar region, an inspersed hamathecium, and dark brown, muriform ascospores occurring 1–2 per ascus. Phylogenetic analyses support placement of the new species in Aptrootia; it is morphologically close to A. elatior but differs in the smaller ascospores and the inspersed hamathecium.

Published: May 2024

AbstractBackgroundEpidemiological data offer conflicting views of the natural course of binge-eating disorder (BED), with large retrospective studies suggesting a protracted course and small prospective studies suggesting a briefer duration. We thus examined changes in BED diagnostic status in a prospective, community-based study that was larger and more representative with respect to sex, age of onset, and body mass index (BMI) than prior multi-year prospective studies.MethodsProbands and relatives with current DSM-IV BED (n = 156) from a family study of BED (‘baseline’) were selected for follow-up at 2.5 and 5 years. Probands were required to have BMI > 25 (women) or >27 (men). Diagnostic interviews and questionnaires were administered at all timepoints.ResultsOf participants with follow-up data (n = 137), 78.1% were female, and 11.7% and 88.3% reported identifying as Black and White, respectively. At baseline, their mean age was 47.2 years, and mean BMI was 36.1. At 2.5 (and 5) years, 61.3% (45.7%), 23.4% (32.6%), and 15.3% (21.7%) of assessed participants exhibited full, sub-threshold, and no BED, respectively. No participants displayed anorexia or bulimia nervosa at follow-up timepoints. Median time to remission (i.e. no BED) exceeded 60 months, and median time to relapse (i.e. sub-threshold or full BED) after remission was 30 months. Two classes of machine learning methods did not consistently outperform random guessing at predicting time to remission from baseline demographic and clinical variables.ConclusionsAmong community-based adults with higher BMI, BED improves with time, but full remission often takes many years, and relapse is common.

Published: May 2024

AbstractDetermining how gas hydrate distribution evolved along continental margins in the past is essential to understanding its evolution in the future. Moreover, hydrate decomposition has been linked to several catastrophic events, including some of the largest submarine landslides on Earth and the massive release of greenhouse gases into the ocean. Offshore Romania, the presence of a second bottom‐simulating reflector (BSR) provides an opportunity to gain valuable insights into hydrate dynamics since the Last Glacial Period (LGP). We conducted transient modeling of hydrate thermodynamic stability by merging in‐situ observations with indirect assessments of sea‐bottom temperature, thermal conductivity, salinity, sedimentation rate, and sea‐level variations. We reveal a strong correlation between the BSRs and the base of the Gas Hydrate Stability Zone (GHSZ) during both the present and LGP periods. The gradual evolution of the GHSZ over the past 34 ka presented here supports a conceptual model that excludes catastrophic environmental scenarios.
