Abstract
Sentiment analysis is becoming a very popular research technique. It can effectively identify hidden emotional trends in social networks to understand people’s opinions and feelings. This research therefore focuses on analyzing the sentiments of the public on the social media platform, YouTube, about the Thailand-China high-speed train project and the Laos-China Railway, a mega-project that is important to the country and a huge investment to develop transportation infrastructure. It affects both the economic and social dimensions of Thai people and is also an important route to connect the rail systems of ASEAN countries as part of the Belt and Road Initiative. We gathered public Thai reviews from YouTube using the Data Application Program Interface. This dataset was used to train six sentiment classifiers using machine learning and deep learning algorithms. The performance of all six models by means of precision, recall, F1-score and accuracy are compared to find the most suitable model architecture for sentiment classification. The results show that the transformer model with the WangchanBERTa language model yields best accuracy, 94.57%. We found that the use of a Thai language-specific model that was trained from a large variety of data sources plays a major role in the model performance and significantly increases the accuracy of sentiment prediction. The promising performance of this sentiment classification model also suggests that it can be used as a tool for government agencies to plan, make strategic decisions, and improve communication with the public for better understanding of their projects. Furthermore, the model can be integrated with any online platform to monitor people's sentiments on other public matters. Regular monitoring of public opinions could help the policy makers in designing public policies to address the citizens’ problems and concerns as well as planning development strategies for the country.
Identifying Neighborhood Effects on Geohazard Adaptation in Mountainous Rural Areas of China: A Spatial Econometric Model
Authors: Peng Li , Tan Jing 
Published: December 2023

AbstractIn mountainous rural settlements facing the threat of geohazards, local adaptation is a self-organizing process influenced by individual and group behaviors. Encouraging a wide range of local populations to embrace geohazard adaptation strategies emerges as a potent means of mitigating disaster risks. The purpose of this study was to investigate whether neighbors influence individuals’ adaptation decisions, as well as to unravel the mechanisms through which neighborhood effects exert their influence. We employed a spatial Durbin model and a series of robustness checks to confirm the results. The dataset used in this research came from a face-to-face survey involving 516 respondents residing in 32 rural settlements highly susceptible to geohazards. Our empirical results reveal that neighborhood effects are an important determinant of adaptation to geohazards. That is, a farmer’s adaptation decision is influenced by the adaptation choices of his/her neighbors. Furthermore, when neighbors adopt adaptation strategies, the focal individuals may also want to adapt, both because they learn from their neighbors’ choices (social learning) and because they tend to abide by the majority’s choice (social norms). Incorporating neighborhood effects into geohazard adaptation studies offers a new perspective for promoting disaster risk reduction decision making.

AbstractHelical hierarchy found in biomolecules like cellulose, chitin, and collagen underpins the remarkable mechanical strength and vibrant colors observed in living organisms. This study advances the integration of helical/chiral assembly and 3D printing technology, providing precise spatial control over chiral nano/microstructures of rod-shaped colloidal nanoparticles in intricate geometries. We designed reactive chiral inks based on cellulose nanocrystal (CNC) suspensions and acrylamide monomers, enabling the chiral assembly at nano/microscale, beyond the resolution seen in printed materials. We employed a range of complementary techniques including Orthogonal Superposition rheometry and in situ rheo-optic measurements under steady shear rate conditions. These techniques help us to understand the nature of the nonlinear flow behavior of the chiral inks, and directly probe the flow-induced microstructural dynamics and phase transitions at constant shear rates, as well as their post-flow relaxation. Furthermore, we analyzed the photo-curing process to identify key parameters affecting gelation kinetics and structural integrity of the printed object within the supporting bath. These insights into the interplay between the chiral inks self-assembly dynamics, 3D printing flow kinematics and photo-polymerization kinetics provide a roadmap to direct the out-of-equilibrium arrangement of CNC particles in the 3D printed filaments, ranging from uniform nematic to 3D concentric chiral structures with controlled pitch length, as well as random orientation of chiral domains. Our biomimetic approach can pave the way for the creation of materials with superior mechanical properties or programable photonic responses that arise from 3D nano/microstructure and can be translated into larger scale 3D printed designs.

Influence of concrete type on rigid pavement behavior under static loads
Authors: Salama Magdy I. , Elayat Amal , Reda Mahmoud , Elsamak Galal 
Published: December 2023

AbstractIt is thought that rigid pavements are more expensive than flexible pavements. However, when taking into account the element of durability, it was found that rigid pavements are less expensive than flexible pavements and have a service life up to 20 years. The flexible pavements are more suitable for the areas with weak subsoil and poor drainage, but it has a negative impact on the environment. This research presents an experimental and numerical study to explore the behavior of rigid pavement made of different types of concrete under the influence of static loads. The recent experimental study consists of six slabs with dimensions of 600 × 600 × 60 mm made of different types of concrete. Such types are normal-strength concrete (NSC), high-strength concrete (HSC) and strain hardening cementitious composites (SHCC). Based on the findings of this study, it is evident that the slab constructed with SHCC exhibits a 76.6% greater bearing capacity compared to the NSC slab. Regarding cost-effectiveness, the HSC slab was identified as the most economically advantageous option. A point to be noted is that the numerical model using the Abaqus program succeeded in modeling the experimental tested slabs.

AbstractThe LUXE experiment is a new experiment in planning in Hamburg, which will study quantum electrodynamics at the strong-field frontier. LUXE intends to measure the positron production rate in this unprecedented regime using, among others, a silicon tracking detector. The large number of expected positrons traversing the sensitive detector layers results in an extremely challenging combinatorial problem, which can become computationally expensive for classical computers. This paper investigates the potential future use of gate-based quantum computers for pattern recognition in track reconstruction. Approaches based on a quadratic unconstrained binary optimisation and a quantum graph neural network are investigated in classical simulations of quantum devices and compared with a classical track reconstruction algorithm. In addition, a proof-of-principle study is performed using quantum hardware.
Anatomical and cytological studies on the cotton leaf worm spodoptera littoralis (Boisd.) larva infected with some bio-insecticides

Published: December 2023

AbstractThis study was conducted to investigate the effect of recommended LC50 concentration of three commercial bio insecticides; (Protecto® (Bacillus thuringiensis kurstaki), Viruset® (Spodoptera littoralis NPV), Profect® (Btk & SpliNPV) on fat body and internal organs of the spodoptera littoralis larva treated with these bio insecticides. The treated larvae were dissected and examined under the converted microscope and transmission electron microscope. Results showed that the three compounds have significant effect on fat bodies and internal organs of larva. The greatest effect was observed by the profect compound followed by protecto and viruset. The combination of bacteria and virus increased the amount of fat body compared with suing virus and bacteria individually. Thus, our findings indicated that the combination of bacteria and virus increased the efficiency of each other.
Violent conflict and the child quantity–quality tradeoff
Authors: Karki Nepal Apsara , Halla Martin , Stillman Steven 
Published: December 2023

Abstract
We show that the exposure to war-related violence increases the quantity of children temporarily, with permanent negative consequences for the quality of the current and previous cohorts. Our empirical evidence is based on Nepal, which experienced a 10 year long civil conflict of varying intensity. We exploit that villages affected by the conflict had the same trend in fertility as non-affected villages prior to the onset of conflict and employ a difference-in-differences estimator. We find that women in affected villages increased their fertility during the conflict by 19%, while child height-for-age declined by 10%. Supporting evidence suggests that the temporary fertility increase was the main pathway leading to reduced child height, as opposed to direct impacts of the conflict.

Abstract
In ultra-short laser pulses, small changes in dispersion properties before the final focusing mirror can lead to severe pulse distortions around the focus and therefore to very different pulse properties at the point of laser–matter interaction, yielding unexpected interaction results. The mapping between far- and near-field laser properties intricately depends on the spatial and angular dispersion properties as well as the focal geometry. For a focused Gaussian laser pulse under the influence of angular, spatial and group-delay dispersion, we derive analytical expressions for its pulse-front tilt, duration and width from a fully analytic expression for its electric field in the time–space domain obtained with scalar diffraction theory. This expression is not only valid in and near the focus but also along the entire propagation distance from the focusing mirror to the focus. Expressions relating angular, spatial and group-delay dispersion before focusing at an off-axis parabola, where they are well measurable, to the respective values in the pulse’s focus are obtained by a ray tracing approach. Together, these formulas are used to show in example setups that the pulse-front tilts of lasers with small initial dispersion can become several tens of degrees larger in the vicinity of the focus while being small directly in the focus. The formulas derived here provide the analytical foundation for observations previously made in numerical experiments. By numerically simulating Gaussian pulse propagation and measuring properties of the pulse at distances several Rayleigh lengths off the focus, we verify the analytic expressions.
“Basically, it’s a History of the Russian State”: Russocentrism, Etatism, and the Ukrainian Question in Stalin’s Editing of the 1937 Short History of the USSR
Authors: Brandenberger David 
Published: December 2023

AbstractJoseph Stalin and the Soviet party leadership launched a major propaganda campaign in 1931 that called for a new approach to Soviet history, not only for scholars and pedagogues but for society as a whole. A veritable “search for a usable past,” this initiative was to bolster the authority and legitimacy of the state and rally the population together in patriotic unity by connecting the prerevolutionary past to the Stalinist present. When this new historical line was finally unveiled in 1937, it challenged earlier Soviet sloganeering on subjects like nationalism, imperialism, and colonialism. This article examines how Stalin attempted to reconcile his new “usable past” with these other ideological priorities, focusing on a case study of the so-called Ukrainian question within the context of the USSR’s broader reevaluation of tsarist-era imperialism and colonial policy.
The “Shop Girl” and White Nationalism: White Working-class Women and Femininity in Johannesburg Department Stores, 1930s–1970s
Authors: Kenny Bridget 
Published: December 2023

AbstractBased on media stories and union campaigns, this paper tracks the discourses from the 1930s to the 1970s around the ‘shop girl’ in Johannesburg. It argues that the shop girl was a figure of white femininity that complicates the now extensive literature on white women in South Africa through its reproduction of the enduring tension of class difference. Through archival research and interviews, the paper shows how the ‘shop girl’ contributed to an ideology of white nationalism, focused more traditionally around motherhood and domesticity. The embodied labor of white women workers in Johannesburg both relied on their femininity and ensured that the affective labor of service work was a site of contradiction and contestation with white middle class women consumers. Class difference could therefore be contained within the semiotics of white nationhood through the site of consumption and retailing.
Scholars Come for the Archbishop: the Afterlife of Archbishop Wulfstan of York, 1023–2023
Authors: Rabin Andrew 
Published: December 2023

ABSTRACTThe purpose of this article is to provide a synoptic view of what Patrick Wormald has aptly called the ‘rather odd’ history of Wulfstan scholarship. In doing so, it will also consider how our understanding of Wulfstan and his writings has been shaped by the historical reliance on stylistic analysis, both as an objective instrument to reconstruct his canon and as a methodological practice subject to personal biases, ideological trends and historical circumstances. Beginning with a discussion of ways that the study of Wulfstan’s style has framed our understanding of both his canon and authorial identity, this article then traces the evolution of Wulfstan scholarship from the sixteenth century to the present. It will conclude with a brief discussion of one of Wulfstan’s least-studied works, the homily On Various Misfortunes (Be mistlican belimpan), to suggest some possible avenues for future study.
Reliable strategies for implementing model-based navigation on fixed-wing drones
Authors: Laupré Gabriel , Pirlet Lucas , Skaloud Jan 
Published: December 2023

AbstractA relatively novel approach of autonomous navigation employing platform dynamics as the primary process model raises new implementational challenges. These are related to: (i) potential numerical instabilities during longer flights; (ii) the quality of model self-calibration and its applicability to different flights; (iii) the establishment of a global estimation methodology when handling different initialisation flight phases; and (iv) the possibility of reducing computational load through model simplification. We propose a unified strategy for handling different flight phases with a combination of factorisation and a partial Schmidt–Kalman approach. We then investigate the stability of the in-air initialisation and the suitability of reusing pre-calibrated model parameters with their correlations. Without GNSS updates, we suggest setting a subset of the state vector as ‘considered’ states within the filter to remove their estimation from the remaining observations. We support all propositions with new empirical evidence: first in model-parameter self-calibration via optimal smoothing and second through applying our methods on three test flights with dissimilar durations and geometries. Our experiments demonstrate a significant improvement in autonomous navigation quality for twelve different scenarios.
Effect of tomato, tomato-derived products and lycopene on metabolic inflammation: from epidemiological data to molecular mechanisms

Published: December 2023

Abstract
The goal of this narrative review is to summarise the current knowledge and limitations related to the anti-inflammatory effects of tomato, tomato-derived products and lycopene in the context of metabolic inflammation associated to cardiometabolic diseases. The potential of tomato and tomato-derived product supplementation is supported by animal and in vitro studies. In addition, intervention studies provide arguments in favour of a limitation of metabolic inflammation. This is also the case for observational studies depicting inverse association between plasma lycopene levels and inflammation. Nevertheless, current data of intervention studies are mixed concerning the anti-inflammatory effect of tomato and tomato-derived products and are not in favour of an anti-inflammatory effect of pure lycopene in humans. From epidemiological to mechanistic studies, this review aims to identify limitations of the current knowledge and gaps that remain to be filled to improve our comprehension in contrasted anti-inflammatory effects of tomato, tomato-derived products and pure lycopene.
The Spiritualist Ear
Authors: Spinner Codee 
Published: December 2023

AbstractDuring the nineteenth century, many heard the afterlife before they could see it. These clairaudient forays took place in the context of spiritualism, a religious movement that facilitated communication between the living and the dead. Although the senses were important to spiritualism, sound was especially crucial for developing cosmologies of the afterlife. Sound can have powerful affective effects, especially in the realm of religion. In the case of spiritualism, however, notions of sound are complicated because of the inclusion of clairaudient and acousmatic sounds. This article analyzes spiritualist soundscapes in terms of acoustemologies, using personal narratives and instructional materials to demonstrate how spiritualists developed a sense of space through sound. Not only does my analysis demonstrate the importance of sound to these spiritual communities, but it also shows that spiritualist conceptions of sound require a special understanding of the nature of sound.

AbstractLarge wildfires are increasing across numerous regions of the globe. While the West has remained a primary focus of wildfire research and resources in the U.S., recent signals suggest that wildfire risk is increasing in the eastern U.S. as well. We conducted an in‐depth assessment of large (>200 ha) wildfire regime characteristics (size, number, total hectares burned, seasonality, probability of occurrence, and ignition source) over a 36‐year period across the Eastern Temperate Forests of the U.S. to quantify geographic patterns in large‐wildfire regime and identify changing spatio‐temporal large wildfire patterns. We found increases in large wildfire size, occurrence, number, and total hectares burned in the southern and eastern regions of the Eastern Temperate Forests. In contrast, large wildfires declined or were minimal in northern ecoregions. We demonstrate increasing large wildfires across some of the most populated regions of the United States.

AbstractFlood exposure has been linked to shifts in population sizes and composition. Traditionally, these changes have been observed at a local level providing insight to local dynamics but not general trends, or at a coarse resolution that does not capture localized shifts. Using historic flood data between 2000-2023 across the Contiguous United States (CONUS), we identify the relationships between flood exposure and population change. We demonstrate that observed declines in population are statistically associated with higher levels of historic flood exposure, which may be subsequently coupled with future population projections. Several locations have already begun to see population responses to observed flood exposure and are forecasted to have decreased future growth rates as a result. Finally, we find that exposure to high frequency flooding (5 and 20-year return periods) results in 2-7% lower growth rates than baseline projections. This is exacerbated in areas with relatively high exposure to frequent flooding where growth is expected to decline over the next 30 years.
