Abstract	Spatiotemporal fusion (STF) is considered as a promising way to produce remote sensing images at fine scales in both space and time by blending two types of satellite images. The learning-based STF approaches with deep convolutional neural networks can provide the unified framework to address both gradual and abrupt changes. This paper intends to develop an enhanced learning-based STF using multiscale attention-aware two-stream convolutional neural networks (MACNN). With a coarse image at the prediction date and two pairs of coarse and fine images at other dates as inputs, it employs a multiscale module to characterize different sizes of objects and a spatial and channel attention module to emphasize important information in feature learning. Two experiments on real Landsat and MODIS images are conducted to demonstrate the effectiveness of the proposed MACNN and it outperforms four existing STF methods in both visual and quantitative.

Abstract	Thermal conductivity plays a significant role in controlling thermal cracking of cement-based materials. In this study, the thermal conductivity of cement paste at an early age was measured by the hot plate method. The test results showed that the thermal conductivity of cement paste decreased with the increase of water/cement ratio and curing age. Meanwhile, a multiphase model for the thermal conductivity of cement paste was proposed and used to study the influence of saturation and curing temperature on the thermal conductivity of cement paste. To determine the parameters involved in this model, the thermal conductivity of each phase in cement paste was calculated by the molecular dynamic simulation method, and the hydration of cement was simulated by the Virtual Cement and Concrete Testing Laboratory. The inversion results showed that the relative error between experimental and simulation results lay between 1.1% and 6.5%. The thermal conductivity of paste in the saturated condition was 14.9-32.3% higher than that in the dry state. With the curing temperature increasing from 10 °C to 60 °C, the thermal conductivity of cement paste decreased by 3.9-4.9% depending on the water/cement ratio.

Abstract	Background: In various surgical specialties, preoperative surgical warm-up has been demonstrated to affect a surgeon's performance and the perioperative outcomes for patients. However, the influence of warm-up activities on video-assisted thoracoscopic surgery lobectomy (VATSL) remains largely unexplored. This study aims to investigate the potential effects of preoperative surgical warm-up on VATSL. Methods: A cohort of 364 patients diagnosed with lung cancer through pathology and undergoing VATSL at the Thoracic Surgery Department of Xuzhou Medical University from January 2018 to September 2022 were included. Patients were categorized into two groups: the warm-up group, comprising 172 patients undergoing their first VATSL of the day, and the warm-up effect group, consisting of 192 patients undergoing their second VATSL on the same day. Propensity score matching was employed to compare operation times and postoperative complications between the two groups, resulting in 159 matched cases in each group. Results: There were no statistically significant differences in operation time (154.5 ± 54.9 vs. 147.2 ± 54.4 min, p = 0.239) and postoperative complications (including pulmonary infection, atelectasis, long-term pulmonary air leakage requiring incision suture in the operating room, and postoperative pleural effusion) (14:22 cases, p = 0.157) between the warm-up and warm-up effect groups. Conclusion: The findings suggest that preoperative surgical warm-up does not significantly affect the perioperative outcomes of VATSL.

Abstract	Factorization machines (FMs) are widely used in recommender systems due to their adaptability and ability to learn from sparse data. However, for the ubiquitous non-interactive features in sparse data, existing FMs can only estimate the parameters corresponding to these features via the inner product of their embeddings. Undeniably, they cannot learn the direct interactions of these features, which limits the model's expressive power. To this end, we first present MixFM, inspired by Mixup, to generate auxiliary training data to boost FMs. Unlike existing augmentation strategies that require labor costs and expertise to collect additional information such as position and fields, these augmented data are only by the convex combination of the raw ones without any professional knowledge support. More importantly, if non-interactive features exist in parent samples to be mixed respectively, MixFM will establish their direct interactions. Second, considering that MixFM may generate redundant or even detrimental instances, we further put forward a novel Factorization Machine powered by Saliency-guided Mixup (denoted as SMFM). Guided by the customized saliency, SMFM can generate more informative neighbor data. Through theoretical analysis, we prove that the proposed methods minimize the upper bound of the generalization error, which positively enhances FMs. Finally, extensive experiments on seven datasets confirm that our approaches are superior to baselines. Notably, the results also show that "poisoning" mixed data benefits the FM variants.

Abstract	The impact protection applications of polycarbonate (PC) products are gradually increasing. Due to the high sensitivity of PC to notches, research on notch impacts has become very important. In this paper, the impact performance of PC with two different molecular weights under different notch states was investigated. Three notch size factors, namely notch tip radius, notch angle, and notch center depth, were selected to design orthogonal experiments and research impact toughness. Subsequently, a single-factor study was conducted on the impact radius at the tip of the notch, which was the most important factor affecting the impact performance. Research shows that the brittle-ductile-transition tip radius of high-molecular-weight PC is 0.15 mm, and it has a higher impact toughness than low-molecular-weight PC during the brittle fracture process. The brittle-ductile-transition tip radius of lower molecular weight is 0.25 mm, while low-molecular-weight PC has a higher impact toughness during the ductile fracture process. The brittle and ductile fracture mechanisms of PC with different molecular weights were analyzed by observing the stress changes and cross-sectional morphology.

Article: Subsistence, Environment, and Society in the Taihu Lake Area during the Neolithic Era from a Dietary Perspective

Abstract	The Taihu Lake region is an important area where China’s rice agriculture originated and where early Chinese civilisation formed. Knowing how this ecologically sensitive area’s Neolithic residents adapted to environmental changes and utilised natural resources is key to understanding the origins of their agricultural practices and civilisation. Focusing on food resources, we systematically organised data from archaeobotanical and zooarchaeological research, human bone stable isotopic analyses, and fatty acid and proteome residue analyses on the Taihu Lake area’s Neolithic findings to explore the interrelationships between subsistence, the environment, and society through qualitative and quantitative analysis supported by paleoenvironmental and archaeological evidence. The results showed that during the Neolithic era (7.0–4.3 ka BP), under a suitable climate with stable freshwater wetland environments, 38 varieties of edible animals and plants were available to humans in the Taihu Lake area. Despite agriculture being an important food source, rice cultivation and husbandry developed at different paces. Paddy rice cultivation began in wetlands and had always dominated the subsistence economy, as although gathering was universal and diverse, it produced a relatively low volume of food. In contrast, husbandry did not provide sufficient meat throughout the 2000 years of the Majiabang and Songze Cultures. Thus, fishing for freshwater organisms and hunting for wild mammals were the main meat sources before the domestication of pigs became the primary source of meat during the Liangzhu Cultural period. With the available wetland ecological resources and paddy rice farming (the sole crop), the Taihu Lake area transformed into an agricultural society in which rice cultivation dominated the Songze Culture’s subsistence economy, which was also the first to exhibit social complexity. Then, finally, early civilisation developed in the Liangzhu Cultural period. This study contributes to understanding the unique evolutionary path of early Chinese civilisation and has important implications on sustainable resource utilisation for constructing ecological civilisations in present-day societies.

Abstract	Vitamin B12 (VB12) is a micronutrient that is essential for DNA synthesis and cellular energy production. We recently demonstrated that VB12 oral supplementation coordinates ileal epithelial cells (iECs) and gut microbiota functions to resist pathogen colonization in mice, but it remains unclear whether VB12 directly modulates the cellular homeostasis of iECs derived from humans. Here, we integrated transcriptomic, metabolomic, and epigenomic analyses to identify VB12-dependent molecular and metabolic pathways in human iEC microtissue cultures. RNA sequencing (RNA-seq) revealed that VB12 notably activated genes involved in fatty acid metabolism and epithelial cell proliferation while suppressing inflammatory responses in human iECs. Untargeted metabolite profiling demonstrated that VB12 facilitated the biosynthesis of amino acids and methyl groups, particularly S-adenosylmethionine (SAM), and supported the function of the mitochondrial carnitine shuttle and TCA cycle. Further, genome-wide DNA methylation analysis illuminated a critical role of VB12 in sustaining cellular methylation programs, leading to differential CpG methylation of genes associated with intestinal barrier function and cell proliferation. Together, these findings suggest an essential involvement of VB12 in directing the fatty acid and mitochondrial metabolisms and reconfiguring the epigenome of human iECs to potentially support cellular oxygen utilization and cell proliferation.

Abstract	Population distribution is the most direct indicator used to describe human activities. Grid-based population distribution maps overcome the drawbacks of statistical data and are thus more suitable for integrated analysis with environmental data. However, current modeling methods seeking to improve accuracy ignore the role of many existing products, resulting in the ineffective use of advantageous information from different gridded population maps. In this study, the multisource map fusion method is developed and combined with population mapping to simply and efficiently achieve improved results accuracy by understanding the uncertainty of different gridded products. Three areas in China with significant environmental differences were used as case studies to validate the results. The case studies use representative Granger-Ramanathan (GR), variance weighted (VW), and random forest (RF) algorithms to implement multisource map fusion for three existing population maps – GPW4, LandScan, and WorldPop. The results of the experiments indicate that fusing multisource population maps can produce a more accurate product than input maps. Compared with the highest accuracy input data, the maximum reduction percentages for the RMSE and MAE of fused maps at the grid scale are 13.66% and 20.39% in the Beijing, Tianjin, and Hebei Region (BTHR); 15.47% and 18.29% in Guangdong Province; and 5.05% and 6.15% in Guizhou Province. This study provides new strategies for producing high-accuracy population distribution maps, and its inexpensive features make it especially suitable for developing countries to produce wide-range gridded population maps that are more accurate than existing products using a few surveys.

Abstract	Ferns are important plants both to ecosystems and humans, while the organic tissues of ferns might be hard to find due to the taphonomical condition. Thus, phytoliths in ferns might provide helpful information while other proxies were absent. In this study, we surveyed the production and morphology of phytoliths in 25 fern species belonging to 15 families. The results showed that more than half of the studied species were non-phytoliths producers, while in phytoliths producers, the production rate could reach 712,995 grains/g of dry material. We confirmed and found that Irregular anticlinal, Prismatic elongate, Elongate sinuate, Spheroidal cavate granulate, Silicified epidermis granulate, Amoeboid branchiate and Prismatic cubic might be the potential diagnostic phytoliths types for ferns.
