Published: December 2024

ABSTRACTThe development of emotion regulation is integral to children's socioemotional adjustment. Respiratory sinus arrhythmia (RSA) reflects parasympathetic regulation of cardiac arousal and is thought to be an indicator of emotion regulation. However, it is unclear how RSA is associated with positive maternal behaviors and infant emotional recovery in real time over the course of a recovery period following a social stressor. Mothers and their 5‐ to 6‐month‐old infants (N = 143) completed the Still Face paradigm. Using a series of autoregressive latent trajectory models, the current study aimed to elucidate the associations among observed maternal warmth, infant RSA, and observed infant negative affect across a 5‐min observation. The hypotheses were that trajectories of maternal warmth would predict trajectories of infant RSA and negative affect, and that trajectories of RSA would be associated with the infants' observed negative affect. Change in maternal warmth was associated with infant negative affect and RSA at the end of the reunion and change in RSA was associated with ultimate levels of negative affect. The results provide partial support for our hypothesis that maternal warmth supports infant physiological, and in turn, emotional recovery.

ABSTRACTParenting that is warm and supportive has been consistently linked to better emotion regulation in children, but less is known about this association in adolescents. Adolescence is thought to be an important period for emotion regulation development given that it coincides with the emergence of mental health issues. Respiratory sinus arrhythmia (RSA) is a measure of parasympathetic regulation linked to emotion and behavior regulation. Despite the well‐documented links between parenting practices and emotion regulation, and between RSA and emotion regulation, few studies have focused on the association between positive parenting and adolescent RSA or included both mothers and fathers. The current study analyzed the influence of warm parenting throughout adolescence (ages 10–16) on basal RSA at age 17 in 229 Mexican‐origin youths. Latent‐growth curve models were used to analyze associations between maternal and paternal warmth and baseline RSA. Changes in maternal, but not paternal, warmth from age 10 to 16 were related to youths’ basal RSA at age 17. Specifically, youths who perceived increasing (or less decreasing) maternal warmth across adolescence had higher basal RSA. This finding suggests that positive maternal parenting experiences during adolescence “get under the skin” to enhance parasympathetic functioning that supports youths’ emotion regulation capacities.

Published: December 2024

ABSTRACTAuditory evoked potential‐age (AEP‐age) is proposed to index auditory maturation and has been found to predict language skills in children with and without a language disorder. However, reporting average effects using linear regression does not fully capitalize on the potential of AEP‐age to estimate individual differences in young children. This study used a quantile regression approach to examine the predictive utility of AEP‐age for 105 typical and neurodiverse 7–10‐year‐old children (61 males; 44 females; largely monolingual English) with varying language skills without creating subgroups. Although linear regression did not find an association between AEP‐age and language skills, the quantile model added specificity by revealing differential associations. AEP‐age was only related to language skills for children at around the median point of the language continuum, but, not for those at the lowest or highest end of the language distribution. Overall, the quantile regression methodology provides us with the flexibility of understanding how AEP‐age is related to different language abilities.

ABSTRACTMethadone and buprenorphine are commonly prescribed during pregnancy to maintain recovery and prevent symptoms of withdrawal in women with opioid use disorder. Infants prenatally exposed to medications for opioid use disorder (MOUD), however, commonly show signs of neonatal opioid withdrawal syndrome (NOWS), which can include feeding‐related issues like hyperphagia. To investigate the effects of prenatal MOUD exposure on feeding behavior, female Sprague‐Dawley rats were implanted with osmotic minipumps filled with methadone, buprenorphine, or saline and subsequently mated. On postnatal day (PND) 1, buprenorphine‐ and methadone‐exposed offspring weighed less than saline‐exposed subjects. Throughout early postnatal development (PND2, 7, and 12), this reduction in weight persisted in buprenorphine, but not methadone, offspring. RNAscope in situ hybridization was then used to measure expression of genes in the nucleus accumbens (NAc) previously associated with hyperphagia in NOWS infants, including proopiomelanocortin (Pomc), neuropeptide Y2 receptors (Npy2r), and dopamine type 2 receptors (Drd2). Distinct developmental expression patterns were noted across the postnatal period, with few effects of MOUD; however, significantly lower Pomc expression was observed in methadone‐exposed but not buprenorphine‐exposed offspring. These findings demonstrate differential effects of methadone and buprenorphine on offspring development and gene expression, highlighting differences in offspring outcomes associated with these two MOUDs.

AbstractThe vibration caused by blasting excavation of rock mass frequently poses a threat to the stability of adjacent tunnels. Previous research is limited by the simplification of a rock mass as a homogeneous elastic medium, without considering the wave attenuation caused by viscoelasticity and wave separation induced by rock discontinuities, as well as plane waves while neglecting geometric attenuation of near‐field nonplane blast waves. This paper establishes a theoretical model of cylindrical P‐wave propagation across a fault to an adjacent existing tunnel. Based on the time‐domain recursive method, vibration equations and peak particle velocity on the adjacent existing tunnel wall caused by a cylindrical wave passing through a fault are derived. The rock mass and fault are assumed to satisfy Kelvin viscoelastic bodies, and contact interfaces between fault and rock mass follow a nonlinear hyperbolic deformation model in the normal direction and a linear model in the tangential direction. The results show that tunnel vibration caused by the blast cylindrical P‐wave is primarily induced by transmitted P‐waves. With the increase of the fault dip angle, vibration on the upper side of the adjacent existing tunnel gradually decreases, while vibration on the lower side increases. The closer the vibration to the upper and lower sides, the stronger the shear effect on the tunnel wall, and the closer the vibration to the middle, the stronger the pressure effect on the tunnel wall. Larger fault thickness and higher initial blast wave frequency result in weaker vibration of the adjacent tunnel. The deeper the burial depth, the stronger the vibration of the adjacent tunnel wall. Findings of this study provide insight into the dynamic response of rock construction and safety evaluation in engineering service.
Repeated fuel treatments fall short of fire‐adapted regeneration objectives in a Sierra Nevada mixed conifer forest, USA

AbstractFire exclusion over the last two centuries has driven a significant fire deficit in the forests of western North America, leading to widespread changes in the composition and structure of these historically fire‐adapted ecosystems. Fuel treatments have been increasingly applied over the last few decades to mitigate fire hazard, yet it is unclear whether these fuel‐focused treatments restore the fire‐adapted conditions and species that will allow forests to persist into the future. A vital prerequisite of restoring fire‐adaptedness is ongoing establishment of fire‐tolerant tree species, and both the type and reoccurrence of fuel treatments are likely to strongly influence stand trajectories. Here, we leveraged a long‐term study of repeated fuel treatments in a Sierra Nevada mixed‐conifer forest to examine the regeneration response of six native tree species to the repeated application of common fuel treatments: prescribed fire, mechanical, mechanical plus fire, and untreated controls. Our objectives were to (1) quantify differences in forest structure and composition following the repeated application of alternative fuel treatments that may influence the establishment environment and then (2) identify the stand structure and climate conditions influencing seedling dynamics. We found that both treatment type and intensity are highly influential in shifting forests toward more fire‐adapted conditions and determining species‐specific regeneration dynamics. Specifically, the conifer species tracked here increased in either colonization or persistence potential following repeated applications of fire, indicating fire may be most effective for restoring regeneration conditions broadly across species. Fire alone, however, was not enough to promote fire‐adapted composition, with concurrent mechanical treatments creating more favorable conditions for promoting colonization and increasing abundances of fire‐tolerant ponderosa pine. Yet, even with repeated fuel treatment application, establishment of fire‐intolerant species far exceeded that of fire‐tolerant species over this 20‐year study period. Moreover, increasing growing season water stress negatively impacted seedling dynamics across all species regardless of treatment type and intensity, an important consideration for ongoing management under heightened climatic stress. While repeated treatments are waypoints in restoring fire‐adapted conditions, more intense treatments via gap‐creation or hotter prescribed fires targeting removal of fire‐intolerant species will be necessary to sustain recruitment of fire‐tolerant species.

AbstractAs natural populations continue to decline globally, direct forms of intervention are increasingly necessary to prevent extinction. One type of intervention, known as demographic rescue, occurs when individuals are added directly to a population to increase abundance and ultimately prevent population extinction. However, the role of infectious disease in demographic rescue remains unknown. To examine the effects of pathogens on demographic rescue, we used a host–pathogen system with the aquatic crustacean Daphnia dentifera as the host and the fungus Metschnikowia bicuspidata as the pathogen. We constructed a randomized 3 × 2 factorial experiment with three rescue treatments (none, low, high) and two pathogen treatments (unexposed, exposed), where the pathogen was introduced via infected individuals during rescue events. We found that adding more individuals to demographically depressed populations increased abundance over the short term; highly supplemented populations initially had 62% more individuals than populations that had no introduced individuals. However, by the end of the experiment, populations that did not have any individuals introduced averaged 640% higher abundance than populations where infected individuals had been added. Thus, the introduction of infected individuals can result in worse demographic outcomes for populations than if no rescue is attempted.
Strong Acid‐Free Homogeneous Catalytic Systems for the Ester Products Synthesis by Alkenes Alkoxycarbonylation: Recent Advances
Authors: Sevostyanova Nadezhda T. , Batashev Sergey A. 
Published: December 2024

AbstractAlkoxycarbonylation represents a method for the ester products synthesis from available reagents – unsaturated compounds, alcohols, and CO. The beginning of research on this reaction was laid in W. Reppe’ works in 1953. In early works, halides and carbonyls of Co, Ni, Rh, and Ir were used as catalysts, and alkoxycarbonylation was often complicated by the unsaturated compounds hydroformylation or alcohol carbonylation. In recent decades, in the presence of the most active and selective Pd‐phosphine systems with strong protonic acids, the products are typically only isomeric esters, which corresponds to the creating waste‐free production principles. At present, a large‐capacity synthesis process for methyl methacrylate, dubbed Alpha, is in operation, with the initial stage being ethylene methoxycarbonylation. In light of these developments, there is a growing interest among chemists and technologists in alkenes alkoxycarbonylation. The use of strong protonic acids as co‐catalysts is essential for the formation of active catalytic complexes. However, these acids are highly corrosive and can cause the alkenes isomerisation. This review is devoted to the analysis of acid‐free homogeneous Pd‐, Ru‐, Co‐, and Ni‐catalysts employed in alkenes alkoxycarbonylation over the past 15 years. As a result, polymers, monomers and other valuable linear and branched esters were obtained.

Published: December 2024

ABSTRACTThis research investigated the combined effect of nano‐silicon dioxide (NSD) and steel fibers (SF) on the structural behavior of reinforced concrete beams. Eight specimens were tested: four without SF and four with SF, with varying NSD percentages (1%, 2%, and 3%) replacing cement. The study examined the mechanical properties of concrete and structural behavior outputs, including load‐deflection, ductility, and damage patterns. Results indicate that NSD significantly enhances compressive strength, with increases of 8.7%, 25.2%, and 32.5% for 1%, 2%, and 3% NSD, respectively. Combined with SF, there are additional improvements in tensile and flexural strengths, leading to higher load capacity and reduced deflection. Beams with 1% steel fibers showed a 30% higher load capacity compared with those without fibers. The ACI code was found to underestimate the load capacity of beams with NSD and SF, indicating the need for updated equations. While NSD increased concrete brittleness, SF enhanced ductility and energy absorption. Future research should focus on optimizing NSD and SF dosages, studying long‐term durability, and validating findings through large‐scale tests.
Enhanced Modeling and Control of Organic Rankine Cycle Systems via AM‐LSTM Networks Based Nonlinear MPC
Authors: Sun Yang , Du Ming , Qi Xiao 
Published: December 2024

ABSTRACTThe organic Rankine cycle (ORC) serves as an effective means of converting low‐grade heat sources into power, playing a pivotal role in environmentally friendly production and energy recovery. However, the inherent complexity, strong and unidentified nonlinearity, and control constraints pose significant challenges to designing an optimal controller for ORC systems. To address these issues, this research introduces a novel modeling and control framework for ORC systems. Leveraging an attention mechanism‐based long short‐term memory (AM‐LSTM) network, the dynamic characteristics of ORC systems, which are subject to non‐Gaussian disturbances, are accurately modeled. A performance metric based on survival information potential (SIP) is developed to optimize the network parameters. Furthermore, a multi‐objective optimization approach that integrates nonlinear model predictive control (NMPC) with the multiverse optimizer (MVO) algorithm is implemented to ensure effective control under varying operating conditions and constraints. Through extensive simulations, the proposed framework demonstrates superior accuracy, robustness, and control performance for ORC systems.

Published: December 2024

ABSTRACTEnsuring a stable supply and demand of food represents a pivotal challenge for sustainable development. This study seeks to delineate the spatiotemporal distribution and circulation patterns of supply and demand for staple crops, identify the major producing and consuming zones in China, and investigate the drivers underpinning efficient coordination of food supply and demand. Results indicate that between 2000 and 2020, China's food supply and demand expanded by 73.8% and 36.62%, respectively, achieving a supply surplus. However, the most significant threats to supply–demand coordination are the extensive use of feed and industrial crops, compounded by the import vulnerabilities arising from global supply chain uncertainties. In terms of major producing and consuming zones, Northeast China plays a vital role in the national food supply, contributing 71% of domestic soybeans, 55% of its maize, and 34% of its rice. Climatic conditions and self‐sufficiency rates are key determinants of provincial supply and demand for staple crops. Provinces such as Sichuan, Hubei, Anhui, and Shandong represent balanced producing–consuming zones for these staple crops. To enhance food supply–demand coordination, tailored and adaptive measures for different provinces are imperative. This study offers theoretical insights to understand the trends of food supply and demand and further contributes to adaptive strategies to address climate change for sustainable food systems.
Authentication of Coffea arabica: Comparative Multispectral Discrimination by NIR and UV–Vis Spectroscopy Aided by Artificial Neural Networks and Data Fusion

Published: December 2024

ABSTRACTCoffea arabica L. (Arabica) is considered the highest quality coffee species and provides the majority of the worldwide production. Among its groups are rare and expensive coffees; consequently, Arabica is subject to fraudulent practices. Currently, a selection of methods allow to precisely discriminate between the primary commercial coffee species (Arabica and Robusta). However, Arabica coffees offer a very restricted genetic diversity, and the authentication of its groups by spectroscopy has not yet been demonstrated to be feasible. This study aimed to step beyond the current state‐of‐the‐art, evaluating the possibility of a multispectral approach to discriminate shelf‐ready coffee beans of the most significant Arabica groups, Typica and Bourbon. Spectral analysis was performed by a benchtop near‐infrared (NIR; 1000–2500 nm), a benchtop ultraviolet–visible (UV–Vis; 200–1000 nm), and a handheld Vis‐NIR (350–2500 nm) spectrometer, hyphenated with nonlinear classification techniques, including artificial neural networks (ANNs). Additionally, low‐level (LLDF) and mid‐level (MLDF) data fusion as well as variable selection (VS) methods were evaluated in their predictive performance. This study successfully demonstrates that closely related Arabica groups are discriminable from each other using a rapid multispectral approach, including direct on‐site analysis. The NIR region provided precise classification of the Arabica coffees (94%–98% accuracy), the Vis‐NIR (88%–93 %), and the UV–Vis (82%–93 %) region showed also good discrimination but left room for improvement. However, an LLDF of the Vis‐NIR and the UV–Vis region in combination with VS proved to be a potent tool to further refine the authentication of coffee groups and showed very good classification accuracies (91%–97%).

Published: December 2024

ABSTRACTIncreasing food sustainability and health benefits is essential to meet the demands of a growing global population while minimizing environmental impact. This study used a green two‐in‐one post pH‐driven processing strategy to develop a sustainable and healthy plant‐based milk alternative. It achieved both extraction and encapsulation in one step by directly incorporating the health‐promoting curcumin from turmeric into soymilk. A high processing efficiency was observed, 94.2% ± 1.6%, with a high extraction efficiency of 96.4% ± 0.5%. Using raw turmeric instead of a purified curcumin significantly enhanced the sustainability in the use of raw materials, for example, reducing the CO2‐eq emissions by 22 times and energy use by 10 times, even with a very small percentage of curcumin (∼0.03 wt%) in the formulation. This strategy underscores the importance of using raw materials and minimizing processing steps to develop more sustainable foods. Additionally, the incorporation of curcumin was found to impart a yellow color to soymilk. No significant changes were observed in other physicochemical properties like particle size, zeta potential, and melting behavior, as most curcumin molecules were encapsulated within the lipid phase of soymilk. The curcumin‐infused soymilk powders also maintained excellent storage stability for 1 month under freezing temperature.

Published: December 2024

AbstractWe use data from the Living Standards Measurement Study—Integrated Surveys on Agriculture and the World Bank Enterprise Survey from seven African countries, to identify agricultural midstream firms and assess their access to credit, comparing them to nonagricultural midstream firms. We find that the agricultural midstream firms are larger and more productive, and are less likely to report barriers to accessing credit, although overall access levels remain low. These findings help build our understanding about the financial needs of micro‐, small‐, and medium‐size enterprises in the agricultural midstream and suggest that more targeted data collection could further this research agenda.
