Authors: HYTTINEN TAPANI , MARTINS MIGUEL , MORASCHINI TOMMASO , QUADRELLARO DAVIDE E. 
Published: October 2024

Abstract
For any

$n<\omega $

we construct an infinite

$(n+1)$

-generated Heyting algebra whose n-generated subalgebras are of cardinality

$\leq m_n$

for some positive integer

$m_n$

. From this we conclude that for every

$n<\omega $

there exists a variety of Heyting algebras which contains an infinite

$(n+1)$

-generated algebra, but which contains only finite n-generated algebras. For the case

$n=2$

this provides a negative answer to a question posed by G. Bezhanishvili and R. Grigolia in [4].

Abstract
In the Highlands of Madagascar, where rice is the main staple food, explosive demographic growth has driven the need for the development of upland rice. In that context, a Participatory Plant Breeding (PPB) program conducted by the FOFIFA-Cirad partnership, aims to develop upland rice varieties adapted to farmers’ needs, with superior agronomic performances, and with high grain zinc concentration. In the area, where ferralitic soils with N and P deficiencies prevail, limited fertilizer usage persists due to elevated costs, and upland rice varieties must adapt to these low fertility environments. Thus, this paper aims to identify the adequate selection conditions and methods that allow combining the above-mentioned criteria for selection. So, 56 rice breeding lines, including high-zinc genotypes, were evaluated in field trials with contrasting fertility conditions. A relative selection efficiency analysis demonstrated that selection for yield should be done in moderate fertility environments, while selection for grain zinc concentration could be done across a diverse range of conditions. Through participatory evaluations, we identified that, for this case, grain appreciation was the most important character for deciding whether to select a line, followed by productivity and earliness. We also noted that farmers were more willing to accept a variety if it had higher grain zinc concentration. Finally, we proposed a selection index that combines agronomic, farmers’ and nutritional criteria, with the purpose of selecting lines that fulfill the expectations on these areas. Overall, this paper proposes an adapted methodology for the combination of PPB and biofortification in marginal environments.
Count Otani Kozui’s 1900 northern cruise: A Japanese “explorer tourist” in the Nordic Arctic
Authors: Ingvarsdóttir Kristín 
Published: October 2024

Abstract
In the year 1900, Otani Kozui, along with three travel companions, ventured on a one-month Arctic cruise, visiting the Norwegian fjords, the North Cape, Spitsbergen (Svalbard) and Iceland. The turn of the 20th century was a formative time for early Arctic tourism, and the aura of exploration was still a part of the northern allure. While Otani and his friends were not the first Japanese to cross the Arctic Circle, they were seen among their contemporaries as holding the record for being the first Japanese to cross the 70th parallel, which became a badge of honour in the exclusive Arctic Circle Society that was established in Japan in the early 1930s. As one of Japan’s most important 20th-century explorers, Otani is well known for having collected and studied Buddhist treasures from across Central Asia and the Silk Road. This paper aims to establish the facts surrounding Otani’s Arctic cruise and the Arctic Circle Society, both of which have gone mostly unnoticed by contemporary scholars. The paper also discusses how Otani’s voyage – which contains elements of tourism, study and competition – should be perceived, both in the context of his legacy and the broader historical developments of the era.
Comparing Canada’s 2018 proposed and 2022 final front-of-pack labelling regulations using generic food composition data and a nationally representative dietary intake survey
Authors: Lee Jennifer J , Mulligan Christine , Ahmed Mavra , L’Abbé Mary R 
Published: October 2024

Abstract

Objective:
The objective of the study was to compare the potential dietary impact of proposed and final front-of-pack labelling (FOPL) regulations (published in Canada Gazette I (CG1) and Canada Gazette II (CG2), respectively) by examining the difference in the prevalence of foods that would require a ‘High in’ front-of-pack nutrition symbol and nutrient intakes from those foods consumed by Canadian adults.

Design:
Foods in a generic food composition database (n 3676) were categorised according to the details of FOPL regulations in CGI and CGII, and the differences in the proportion of foods were compared. Using nationally representative dietary survey data, potential intakes of nutrients from foods that would display a ‘High in’ nutrition symbol according to CGI and CGII were compared.

Setting:
Canada

Participants:
Canadian adults (≥ 19 years; n 13 495)

Results:
Compared with CGI, less foods would display a ‘High in’ nutrition symbol (Δ = –6 %) according to CGII (saturated fat = –4 %, sugars = –1 %, sodium = –3 %). Similarly, potential intakes of nutrients-of-concern from foods that would display a ‘High in’ nutrition symbol were reduced according to CGII compared with CGI (saturated fat = –21 %, sugars = –2 %, sodium = –6 %). Potential intakes from foods that would display a ‘High in’ nutrition symbol were also reduced for energy and nutrients-to-encourage, including protein, fibre, calcium and vitamin D.

Conclusions:
Changes to FOPL regulations may have blunted their potential to limit intakes of nutrients-of-concern; however, they likely averted potential unintended consequences on intakes of nutrients-to-encourage for Canadians (e.g. calcium and vitamin D). To ensure policy objectives are met, FOPL regulations must be monitored regularly and evaluated over time.

Abstract

Aims:
This study aimed to assess the operational efficiency of Sub-District or Tambon Health Promoting Hospitals (THPHs) in Thailand’s Eastern Economic Corridor (EEC) and to propose management guidelines for future improvements.

Background:
The current state of Thailand’s public health demonstrates that government policy has prioritized equal access to public health services in all areas. This increases the need for primary public health services, yet resources are limited and cannot be increased to meet the growing demand. The only effective way to address this issue is to develop the efficiency of public health operations.

Methods:
The sample consisted of 104 THPHs in Chachoengsao, a province in Thailand’s EEC. Data for five input and seven output variables were collected between September 18 and November 15, 2023. An online survey was conducted to gather the required data for fiscal year 2022. Data envelopment analysis was used to measure the efficiency of THPHs.

Findings:
The average efficiency index of the 104 THPHs was 0.9066, with about 60% having an efficiency index of 1.00. When classified by size, it was found that the efficiency levels of the THPHs grew with size, considering that the average efficiency index of the small, medium, and large THPHs was 0.8642, 0.9140, and 0.9417, respectively. The proportion of efficient THPHs also increased with size, at 58.14%, 60.00%, and 66.67%, respectively. Regarding efficiency improvement targets, small THPHs had the highest output targets (28.40%), followed by medium THPHs (15.31%) and large THPHs (9.91%). For the inefficient THPHs, some management guidelines were made to improve their future performances.

Published: October 2024

AbstractSocial networks have become a common way for people to communicate with each other and share ideas, thanks to their fast information-sharing features. But fake news spread on social networks can cause many negative consequences by affecting people’s daily lives. However, the literature lacks online and real-time fake news detection systems. This study aims to fill this gap in the literature and to handle the fake news detection problem with a system called FANDC, based on cloud computing, to cope with fake news in seven different categories, and to solve the real-time fake news detection problems. The system was developed using the CRISP-DM methodology with a hybrid approach. BERT algorithm was used in the system running on the cloud to avoid possible cyber threats with the dataset created with approximately 99 million big data from COVID-19-TweetIDs GitHub repository. It was trained in two periods with 100% accuracy during the modeling phase in terms of training accuracy. Experimental results of the FANDC system performed the real-time detection of fake news at 99% accuracy. However, previous studies experimental level success rate in the literature, were around 90%. We hope that the developed system will greatly assist social network users in detecting fake news in real-time.
The impact of hydroclimate-driven periodic runoff on hydropower production and management
Authors: Hao Shuang , Wörman Anders , Brandimarte Luigia 
Published: October 2024

AbstractThis study evaluates the impact of hydroclimate-driven periodic runoff on hydropower operations and production, with a focus on how the forecasted biennial periodicity of runoff time series could affect the efficiency of hydropower generation. Hydrologic stochastic processes are utilized to forecast long-term runoff, and seven hydroclimate scenarios are developed to be input into a production management model, allowing for an analysis of how periodic hydroclimate variations influence hydropower management and output. The results reveal that the biennial alternation between wet and dry years is a key factor affecting hydropower operations in the Dalälven River Basin. Notable differences between wet- and dry-year scenarios were observed in terms of power efficiency, production output, and forecasting accuracy. Operating hydropower systems based on dry-year runoff forecasts in wet years results in a 1.63% decrease in production efficiency and a reduction of 9,104 MWh in power generation. Conversely, applying wet-year forecasts in dry years slightly boosts production efficiency by 0.31% and increases power generation by 7,832 MWh. Scenarios that adhere to biennial periodicity offer the highest forecasting accuracy, particularly when applying dry-year forecasts in dry years in winter and spring, which produce the most precise predictions. In contrast, using dry-year forecasts in wet years results in the lowest forecasting accuracy.

Published: October 2024

AbstractPolyether sulfone sulfamic acid (PES-NHSO3H) was prepared by simple sulfonation of a modified polyether sulfone. The number of acidic sites (SO3H) was determined to be 4.23 mmol H+/g by acid-base titration and 4.29 mmol H+/g by barium sulfate test. PES-NHSO3H was used as an efficient acidic catalytic system for the preparation of functionalized furan-2-ones and 2ʹ,5-dioxo-5 H-spiro[furan-2,3 ʹ -indoline]-3-carboxylate derivatives via the three-component reaction of anilines, aldehydes/1-ethylindoline-2,3-dione, and diethyl acetylene dicarboxylate in high yields (85–97%). The effect of polar and non-polar solvents on the productivity of the reaction was investigated. The catalyst was recovered 11 times without losses in catalytic potential.

Published: October 2024

Context The genotype of laying hens is one of the most important factors influencing their carcass composition and anatomical features. Aims The aim of the present study was to compare two genotypes of laying hens, Lohmann Brown and Lohmann White, after the laying period. Methods The experimental material consisted of 26 carcasses obtained after slaughtering spent laying hens at the age of 83 weeks. Key results The genotype of the birds had a significant (P < 0.05) effect on carcass weight, and the proportion (%) of the breast muscle, leg muscle and gizzard weight. Significant correlations were also found between bodyweight and the weight of the stomach, proventriculus, liver and spleen. The origin of the laying hens also had a significant impact on the length of the sections on intestinal segments, namely, jejunum, ileum and colon. Significant differences in the correlations between bodyweight and length of duodenum, jejunum and rectum were also found. The compared hybrids of laying hens differed significantly in the dimensions of the femur and tibia. Lohmann Brown (LB) hens were characterized by higher greatest length, medial length, smallest breadth of the corpus, and greatest breadth of the distal end of the femur compared with Lohmann White (LW) hens. Dimensions of the tibia greatest length, axial length, smallest breadth of the corpus, greatest breadth of the distal end and greatest depth of the distal end in LB hens were also significantly (P < 0.05) higher than those in LW hens. Conclusions The results showed that the genotype of laying hens tested after the laying period influenced carcass weight and muscle percentage, as well as differentiated the birds in terms of dimensions of individual segments of the digestive tract, femur, and tibia bones. Implications The results of this research may be useful for consumers of laying hen carcasses and people interested in poultry anatomy.
Fluorescence by incoherently pumped polar quantum dot placed in a low-frequency monochromatic field
Authors: Soldatov A V 
Published: October 2024

Abstract
We studied spectral properties of high-frequency fluorescent radiation from a two-level quantum system with broken inversion spatial symmetry, which can be implemented as a model of a one-electron two-level asymmetric polar semiconductor quantum dot whose electric dipole moment operator has permanent unequal diagonal matrix elements. The case of the excitation of this system by incoherent pumping of some sort supplemented with an additional driving monochromatic field, which frequency is much lower than the optical transition frequency of the quantum dot, was considered. An analytical expression for the fluorescence spectrum as a function of the amplitude and frequency of the monochromatic driving field, as well as of the pumping intensity, was derived. We also discussed feasible practical applications of the effects under study in the field of quantum optics and optoelectronics for the generation of high-frequency radiation, possessing stationary equidistant spectrum, and for the control of the radiative properties of such nanodevices as spasers (dipole nanolasers).
Exactly solvable non-unitary time evolution in quantum critical systems I: effect of complex spacetime metrics
Authors: Wen Xueda 
Published: October 2024

Abstract
In this series of works, we study exactly solvable non-unitary time evolutions in one-dimensional quantum critical systems ranging from quantum quenches to time-dependent drivings. In this part I, we are motivated by the recent works of Kontsevich and Segal (2021 arXiv:2105.10161) and Witten (2021 arXiv:2111.06514) on allowable complex spacetime metrics in quantum field theories. In general, such complex spacetime metrics will lead to non-unitary time evolutions. In this work, we study the universal features of such non-unitary time evolutions based on exactly solvable setups. Various physical quantities including the entanglement Hamiltonian and entanglement spectrum, entanglement entropy, and energy density at an arbitrary time can be exactly solved. Due to the damping effect introduced by the complex time, the excitations in the initial state are gradually damped out in time. The non-equilibrium dynamics exhibit universal features that are qualitatively different from the case of real-time evolutions. For instance, for an infinite system after a global quench, the entanglement entropy of the semi-infinite subsystem will grow logarithmically in time, in contrast to the linear growth in a real-time evolution. Moreover, we study numerically the time-dependent driven quantum critical systems with allowable complex spacetime metrics. It is found that the competition between driving and damping leads to a steady state with an interesting entanglement structure.
Fundamentals of Multicomponent High-Entropy Materials
Authors: Cantor Brian 
Published: October 2024

Abstract
Human development has been a continuing attempt to use new materials in ever more sophisticated ways to enhance the quality of human life. For millennia, we have always made things by taking a main material and then mixing it with small alloying additions to achieve the final required properties. But recently, there has been a revolution as we have discovered how to make much more complex mixtures, providing a bewildering number, literally trillions and trillions, of completely new materials, requiring entirely new scientific theories, and massively extending our ability to make useful products. These new materials are called multicomponent or high-entropy materials. This is the first textbook on the fundamentals of these new materials. It concentrates on the main new concepts and theories that have been developed and provides a summary of the state of play for researchers as well as for students and newcomers entering the field. It is written by the scientist who first discovered multicomponent high-entropy materials. It includes contextual chapters on the history and future potential for developing humankind as driven by the discovery of new materials, and core chapters on methods for discovering and manufacturing multicomponent high-entropy materials, their underlying thermodynamic and atomic and electronic structures, their physical, mechanical and chemical properties, and their potential applications.

Published: October 2024

Background:
Extracellular matrix protein 1 (ECM1) can inhibit TGFβ activation, but its antifibrotic action remains largely unknown. This study aims to investigate ECM1 function and its physical interaction with the profibrotic connective tissue growth factor (CTGF) in fibrosis and ductular reaction (DR).

Methods:

Ecm1 knockouts or animals that ectopically expressed this gene were subjected to induction of liver fibrosis and DR by feeding 3,5-diethoxycarbonyl-1,4-dihydrocollidine (DDC) or α-naphthyl-isothiocyanate (ANIT). ECM1 and CTGF were also examined in the livers of patients with alcohol-associated liver disease (ALD) or ethanol-exposed animals that were fed the western diet for 4 months in the WDA model with liver pathology resembing ALD in patients.

Results:
ECM1 bound to CTGF in yeast two-hybrid systems, cultured liver cells, and cholestatic livers damaged by DDC or α-naphthyl-isothiocyanate. This interaction blocked integrin αvβ6-mediated TGFβ activation, thereby reducing fibrotic responses in vitro. ECM1 downregulation was associated with biliary CTGF induction during human ALD progression. In experimental models, Ecm1 loss enhanced susceptibility to DDC-induced cholestasis with upregulation of Ctgf, αvβ6, alpha-smooth muscle actin, procollagen type I, serum transaminase, and total bilirubin levels in germline knockouts, whereas forced expression of this gene significantly attenuated DR and biliary fibrosis after the feeding of DDC or α-naphthyl-isothiocyanate containing diets. Moreover, ectopic Ecm1 inhibited not only alcohol-associated fibrosis but also TGFβ-mediated deregulation of hepatocyte nuclear factor 4α, preventing the production of the fetal p2 promoter-driven isoforms in the WDA model.

Conclusions:
We uncover a novel antifibrotic action by ECM1 that binds CTGF and inhibits integrin αvβ6-mediated TGFβ activation. Targeting its loss has therapeutic potential for the treatment of DR and liver fibrosis in chronic conditions, such as cholangiopathy and ALD.

Published: October 2024

Background:
Food addiction is a chronic psychological disorder resulting from repeated consumption of highly palatable foods, leading to physical and mental harm. It involves individuals who struggle to control their intake of high-energy, high-fat, and high-sugar foods, often experiencing withdrawal reactions and intense cravings that trigger binge eating during stress. Recent research has focused on the impact of food addiction on physical health, nutrition, and mental well-being. This study aims to review and analyze current evidence on food addiction to advance research in China.

Methods:
A total of 941 articles on food addiction published between January 2013 and April 2023 were analyzed using the Web of Science Core Collection. CiteSpace software was utilized to identify research trends, collaborations among disciplines, authors, and institutions, as well as key topics and emerging keywords.

Results:
The number of publications on food addiction has steadily increased over the past decade, with the United States leading in research output (393 articles). The University of Michigan and author Gearhardt AN were prominent contributors. Key research topics included obesity, eating disorders, addiction, and overeating. Emerging themes encompassed obesity psychology, food composition, brain function, and behavioral addiction.

Conclusion:
Global research on food addiction primarily focuses on understanding the psychological and neurological underpinnings, metabolic implications, addictive behaviors, and treatment modalities such as sleeve gastrectomy. Future research aims to develop personalized prevention and intervention strategies for food addiction.
