To date, there are few studies on loneliness interventions in lower-resource settings. Based on participatory action research methods that are theoretically informed by the social relationship expectations framework, we developed a loneliness intervention called amanane using the photovoice method with older Myanmar migrants in northern Thailand. The aim of our study was to test the feasibility and preliminary effectiveness of photovoice as an intervention for lonely older adults. Over 6 weeks, we coproduced 5 weekly workshops, individual interviews, and a photo exhibition with an older Myanmar migrant cofacilitator and nine participants (57–82 years old). The workshops focused on older people's care provisions. The qualitative evaluation entailed group discussions, interviews, and videos. Results indicated a perfect completion rate and high acceptability. Participants reported a reduction in loneliness due to opening up to each other through photography, feeling united despite cultural differences, and feeling valued by visitors attending the photo exhibition. Overall, photovoice may be a promising intervention for lonely older adults and has the potential to be tested in larger trials across diverse settings.","PeriodicalId":8250,"journal":{"name":"Annals of the New York Academy of Sciences","volume":"1544 1","pages":"65-77"},"PeriodicalIF":4.1,"publicationDate":"2025-01-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/nyas.15270","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143050929","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, vegetation itself plays a fundamental role in shaping Earth's climate by regulating the energy, water, and biogeochemical cycles across terrestrial landscapes. It exerts influence by consuming water resources through transpiration and interception, lowering atmospheric CO2 concentration, altering surface roughness, and controlling net radiation and its partitioning into sensible and latent heat fluxes. This influence propagates through the atmosphere, from microclimate scales to the entire atmospheric boundary layer, subsequently impacting large-scale circulation and the global transport of heat and moisture. Understanding the feedbacks between vegetation and atmosphere across multiple scales is crucial for predicting the influence of land use and land cover changes, and for accurately representing these processes in climate models. This review discusses the biophysical and biogeochemical mechanisms through which vegetation modulates climate across spatial and temporal scales. Particularly, we evaluate the influence of vegetation on circulation patterns, precipitation, and temperature, considering both long-term trends and extreme events, such as droughts and heatwaves. Our goal is to highlight the state of science and review recent studies that may help advance our collective understanding of vegetation feedbacks and the role they play in climate.","PeriodicalId":8250,"journal":{"name":"Annals of the New York Academy of Sciences","volume":"1544 1","pages":"27-41"},"PeriodicalIF":4.1,"publicationDate":"2025-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/nyas.15286","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143026452","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, CNNs struggle with long-term dependencies in sequential EEG data. Models like long short-term memory and transformers improve performance but still face challenges of computational efficiency and long sequences. Mamba, a state space model–based method, excels in modeling long sequences. To overcome the limitations of existing EEG decoding models and exploit Mamba's potential in EEG analysis, we propose MI-Mamba, a model integrating CNN with Mamba for motor imagery (MI) data decoding. MI-Mamba processes multi-channel EEG signals through a single convolutional layer to capture spatial features in the local temporal domain, followed by a Mamba module that processes global temporal features. A fully connected, layer-based classifier is used to derive classification results. Evaluated on two public MI datasets, MI-Mamba achieves 80.59% accuracy in the four-class MI task of the BCI Competition IV 2a dataset and 84.42% in the two-class task of the BCI Competition IV 2b dataset, while reducing parameter count by nearly six times compared to the most advanced previous models.

This study delves into the cognitive and neural bases of math avoidance behavior in HMA through the lens of reward processing. In Experiment 1, participants reported their satisfaction level in response to the reward provided after solving an arithmetic problem. In Experiment 2, participants weighed the economic benefits against the cognitive costs of solving a calculation problem. This decision-making process was framed in terms of either retaining or losing some monetary reward, creating positive or negative contexts, respectively. Experiment 1 showed that HMA participants were more punishment-sensitive and less satisfied with incorrect answers. Experiment 2 revealed that HMA individuals were less willing to tackle math challenges when their satisfaction dipped after errors. HMAs exhibited increased math avoidance and a notably reduced P3 amplitude in negative contexts, a response unique to the HMA group. HMAs also displayed an elevated feedback-related negativity amplitude in both contexts. This study suggests a potential impairment in reward processing in negative contexts and under negative appraisal among those with high math anxiety.","PeriodicalId":8250,"journal":{"name":"Annals of the New York Academy of Sciences","volume":"1544 1","pages":"92-105"},"PeriodicalIF":4.1,"publicationDate":"2025-01-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142975526","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This scoping review aimed to identify and describe DTTs used in fortification programs. We searched peer-reviewed and gray literature and conducted 17 stakeholder surveys. We then mapped DTTs identified against the fortification and nutrition data value chains. Of 11,741 articles identified, 158 met the inclusion criteria. From the included articles and stakeholder surveys, 125 DTTs were identified across three categories: software and tooling (n = 58), data and information lifecycle (n = 50), and hardware and infrastructure (n = 17). Gaps were identified in processing, post-harvest storage, aggregation, and transport nodes of the fortification value chain, and data prioritization, translation/dissemination, and decision-making nodes of the nutrition data value chain. DTTs have the potential to address challenges faced by fortification stakeholders to generate and use data to improve program decision making and nutritional impact.

First, we examine overall trends in healing Acomys tissues, including the cellular stress response, the ability to activate and maintain cell cycle progression, and the expression of certain features in reproductive adults that are normally associated with embryos. Second, we focus on specific cell types that exhibit precisely regulated proliferation to restore missing tissue. While Acomys utilize many of the same cell types involved in scar formation, these cells exhibit divergent activation profiles during regenerative healing. Considered together, current lines of evidence support sustained deployment of proregenerative pathways in conjunction with transient activation of fibrotic pathways to facilitate regeneration and improve tissue repair in Acomys.","PeriodicalId":8250,"journal":{"name":"Annals of the New York Academy of Sciences","volume":"1544 1","pages":"5-26"},"PeriodicalIF":4.1,"publicationDate":"2025-01-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142975180","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These features are concatenated to form a new feature called LMGC, which serves as input data for the four branches of FUSION-ANN. The network performs AE signal recognition and classification through forward propagation in each branch, utilizing multi-level feature fusion. We evaluate FUSION-ANN's performance on the ORION-AE benchmark dataset, which contains AE signals from various loading conditions simulating loosening phenomena in aeronautics, automotive, and civil engineering structures. Our results demonstrate an impressive average accuracy of 98% in AE signal classification. Additionally, FUSION-ANN boasts high training efficiency, robustness, and accuracy, making it suitable for reliable AE signal analysis. However, given the current limitations, we aim to conduct more comprehensive investigations in the future. Our plan includes further testing of the network's performance across various categories of AE signals to assess its generality.

This study aims to analyze the impact of many uncertainty factors on the projected greenhouse gas (GHG) emissions by 2050 for major emitting countries following their net-zero pathways, and their aggregate impact on global GHG emissions. Global emission projections range from 23 to 40 gigatons of CO2 equivalent (GtCO2eq), with a median of 31 GtCO2eq. Our full range corresponds to about 40–75% of 2015 emission levels, which is much wider than the range of 30–45% reported by various integrated assessment models. The main factors contributing to this divergence are the uncertainty in the gas coverage of net-zero targets and uncertainty in the socioeconomic baseline. Countries with net-zero GHG targets by 2050 have a small range of 2050 emissions, while countries with net-zero targets beyond 2050 and unclear coverage, such as China, India, and Indonesia, have a large range of emissions by 2050.","PeriodicalId":8250,"journal":{"name":"Annals of the New York Academy of Sciences","volume":"1544 1","pages":"209-222"},"PeriodicalIF":4.1,"publicationDate":"2025-01-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/nyas.15285","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142962716","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To do so, we consider multiple gender-related factors and the role of the social environment, particularly societal ideologies about what gender is and how it should be expressed. We provide examples of how this expanded conceptualization can contribute to an improved understanding of loneliness by focusing on the impact of gender nonconformity, gendered life experiences, and couple relationships. We highlight the need for more research and evidence to fill existing gaps in understanding. We conclude that the field can move forward by considering the role of biological sex, gender identity, gender expression, gender roles, gender relational experiences, and sexual orientation, as well as the social norms against which these are experienced. To truly examine the role of gender in loneliness, we need to consider the normative context where some, but not others, are minoritized and marginalized, as well as move beyond binary notions of gender to include those with nonbinary, transgender, and intersex identities.","PeriodicalId":8250,"journal":{"name":"Annals of the New York Academy of Sciences","volume":"1544 1","pages":"55-64"},"PeriodicalIF":4.1,"publicationDate":"2025-01-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/nyas.15283","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142929353","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Casque function is debated but appears central to aerial jousting, where birds (typically males) collide casques at high speeds in a mid-flight display that is audible for more than 100 m. We characterized the structural relationship between the skull and casque anatomy using X-ray microtomography and quantitative trabecular network analysis to examine how the casque sustains extreme impact. The casque comprises a keratin veneer (rhamphotheca, ∼8× thicker than beak keratin), which slots over the internal bony casque like a tight-fitting sheath. The bony casque's central cavity contains a network of trabeculae—heavily aligned and predominantly rod-like, among the thickest described in vertebrates—forming a massive rostrocaudal strut spanning the casque's length, bridging rostral (impact), and caudal (braincase) surfaces. Quantitative network characterizations indicate no differences between male and female trabecular architectures. This suggests that females may also joust or that casques play other roles. Our results argue that the casque's impact loading demands and shapes a high-safety-factor construction that involves extreme trabecular morphologies among vertebrates, architectures that also have the potential for informing the design of collision-resistant materials.","PeriodicalId":8250,"journal":{"name":"Annals of the New York Academy of Sciences","volume":"1544 1","pages":"78-91"},"PeriodicalIF":4.1,"publicationDate":"2025-01-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/nyas.15254","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142935354","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
