African Swine Fever (ASF) is one of the most challenging swine diseases that has a significant impact on global pig farming from both sanitary and economic perspectives. The virus causes mortality rates of up to 95‒100% when it enters a population of domestic pigs, and the absence of treatment and vaccines makes controlling and eradication of ASF a challenging task. Therefore, rapid outbreak detection and strict sanitary measures are crucial tools in combating the disease. Free-range pig farming systems can increase the risk of ASF spreading as pigs have more access to the environment and other animals. This can lead to the disease rapidly spreading, especially if infected wild boars come into contact with domestic pigs. To prevent the spread of ASF, it is necessary to implement comprehensive measures, including increasing the level of biosecurity on pig farms and strict compliance with the rules for animal transportation.

Published: January 2024

Background: Sodium-dependent glucose cotransporter 2 (SGLT2) mediates glucose reabsorption in the renal proximal tubules, and SGLT2 inhibitors are used as therapeutic agents for treating type 2 diabetes mellitus. This study aimed to elucidate the effects and mechanisms of SGLT2 inhibition on hepatic glucose metabolism in both serum deprivation and serum supplementation states.Methods: Huh7 cells were treated with the SGLT2 inhibitors empagliflozin and dapagliflozin to examine the effect of SGLT2 on hepatic glucose uptake. To examine the modulation of glucose metabolism by SGLT2 inhibition under serum deprivation and serum supplementation conditions, HepG2 cells were transfected with SGLT2 small interfering RNA (siRNA), cultured in serum-free Dulbecco’s modified Eagle’s medium for 16 hours, and then cultured in media supplemented with or without 10% fetal bovine serum for 8 hours.Results: SGLT2 inhibitors dose-dependently decreased hepatic glucose uptake. Serum deprivation increased the expression levels of the gluconeogenesis genes peroxisome proliferator-activated receptor gamma co-activator 1 alpha (PGC-1α), glucose 6-phosphatase (G6pase), and phosphoenolpyruvate carboxykinase (PEPCK), and their expression levels during serum deprivation were further increased in cells transfected with SGLT2 siRNA. SGLT2 inhibition by siRNA during serum deprivation induces nuclear localization of the transcription factor forkhead box class O 1 (FOXO1), decreases nuclear phosphorylated-AKT (p-AKT), and p-FOXO1 protein expression, and increases phosphorylated-adenosine monophosphate-activated protein kinase (p-AMPK) protein expression. However, treatment with the AMPK inhibitor, compound C, reversed the reduction in the protein expression levels of nuclear p- AKT and p-FOXO1 and decreased the protein expression levels of p-AMPK and PEPCK in cells transfected with SGLT2 siRNA during serum deprivation.Conclusion: These data show that SGLT2 mediates glucose uptake in hepatocytes and that SGLT2 inhibition during serum deprivation increases gluconeogenesis via the AMPK/AKT/FOXO1 signaling pathway.

Published: January 2024

Inflacija je kao ekonomska pojava trajnog rasta opće razine cijena prisutna od davne povijesti, od pojave novca kao sredstva plaćanja. U današnjim gospodarskim sustavima smatra se pravilom, a ne iznimkom. Završetak Drugog svjetskog rata u Europi potaknuo je ideju o osnivanju zajednice europskih zemalja koje bi imale i zajedničku valutu. Ideja je brzo realizirana i zemlje su se počele ujedinjavati u Europsku uniju, a ugovorom o osnivanju određeno je da će Europska unija biti monetarna unija. Ubrzo nakon osnivanja Europske unije, članice počinju uvoditi euro kao zajedničku valutu. Ulaskom Republike Hrvatske u Europsku uniju, pred Republiku Hrvatsku stavljena je mogućnosti uvođenja zajedničke valute. Euro je zamijenio hrvatsku kunu kao službenu valutu u Republici Hrvatskoj 1. siječnja 2023. godine. Uvođenje eura izazvalo je negodovanje dijela javnosti, a strah je jednim dijelom bio izazvan brigom da bi zamjena valuta mogla povećati inflaciju. U radu se analizira učinak uvođenja eura u Republici Hrvatskoj na kretanje neto plaća, kretanje cijena dobara i usluga, kretanje nezaposlenosti i kretanje inflacije.

Exact Jacobi elliptic solutions of some models for the interaction of long and short waves
Authors: Brewer Bruce , Daniels Jake , Nguyen Nghiem V.
Published: January 2024

Some systems were recently put forth by Nguyen et al. as models for studying the interaction of long and short waves in dispersive media. These systems were shown to possess synchronized Jacobi elliptic solutions as well as synchronized solitary wave solutions under certain constraints, i.e., vector solutions, where the two components are proportional to one another. In this paper, the exact periodic traveling wave solutions to these systems in general were found to be given by Jacobi elliptic functions. Moreover, these cnoidal wave solutions are unique. Thus, the explicit synchronized solutions under some conditions obtained by Nguyen et al. are also indeed unique.
Ultra-high-dimensional feature screening of binary categorical response data based on Jensen-Shannon divergence
Authors: Jiang Qingqing , Deng Guangming
Published: January 2024

Currently, most of the ultra-high-dimensional feature screening methods for categorical data are based on the correlation between covariates and response variables, using some statistics as the screening index to screen important covariates. Thus, with the increasing number of data types and model availability limitations, there may be a potential problem with the existence of a class of unimportant covariates that are also highly correlated with the response variable due to their high correlation with the other covariates. To address this issue, in this paper, we establish a model-free feature screening procedure for binary categorical response variables from the perspective of the contribution of features to classification. The idea is to introduce the Jensen-Shannon divergence to measure the difference between the conditional probability distributions of the covariates when the response variables take on different values. The larger the value of the Jensen-Shannon divergence, the stronger the covariate's contribution to the classification of the response variable, and the more important the covariate is. We propose two kinds of model-free ultra-high-dimensional feature screening methods for binary response data. Meanwhile, the methods are suitable for continuous or categorical covariates. When the numbers of covariate categories are the same, the feature screening is based on traditional Jensen-Shannon divergence. When the numbers of covariate categories are different, the Jensen-Shannon divergence is adjusted using the logarithmic factor of the number of categories. We theoretically prove that the proposed methods have sure screening and ranking consistency properties, and through simulations and real data analysis, we demonstrate that, in feature screening, the approaches proposed in this paper have the advantages of effectiveness, stability, and less computing time compared with an existing method.
Adaptive prescribed performance control for wave equations with dynamic boundary and multiple parametric uncertainties
Authors: Xu Zaihua , Li Jian
Published: January 2024

In modern engineering, the dynamics of many practical problems can be described by hyperbolic distributed parameter systems. This paper is devoted to the adaptive prescribed performance control for a class of typical uncertain hyperbolic distributed parameter systems, since uncertainties are inevitable in practice. The systems in question simultaneously have unknown in-domain spatially varying damping coefficient and unknown boundary constant damping coefficient. Moreover, dynamic boundary condition is considered in the present paper. These characteristics make the control problem in the paper essentially different from those in the related works. To solve the problem, using adaptive technique based projection operator, backstepping method developed for ODEs and Lyapunov stability theories, a powerful adaptive prescribed performance control scheme is proposed to successfully guarantee that all states of the resulting closed-loop system are bounded, furthermore, the original system state converges to an arbitrary prescribed small neighborhood of the origin. Compared with the existing results, the developed control schemes can not only effectively handle the serious uncertainties, but also overcome the technical difficulties in the infinite-dimensional backstepping control design method caused by the dynamic boundary condition and guarantee prescribed performance.
Forecasting stock prices using a novel filtering-combination technique: Application to the Pakistan stock exchange
Authors: Iftikhar Hasnain , Khan Murad , Turpo-Chaparro Josué E. , Rodrigues Paulo Canas , López-Gonzales Javier Linkolk
Published: January 2024

Traders and investors find predicting stock market values an intriguing subject to study in stock exchange markets. Accurate projections lead to high financial revenues and protect investors from market risks. This research proposes a unique filtering-combination approach to increase forecast accuracy. The first step is to filter the original series of stock market prices into two new series, consisting of a nonlinear trend series in the long run and a stochastic component of a series, using the Hodrick-Prescott filter. Next, all possible filtered combination models are considered to get the forecasts of each filtered series with linear and nonlinear time series forecasting models. Then, the forecast results of each filtered series are combined to extract the final forecasts. The proposed filtering-combination technique is applied to Pakistan's daily stock market price index data from January 2, 2013 to February 17, 2023. To assess the proposed forecasting methodology's performance in terms of model consistency, efficiency and accuracy, we analyze models in different data set ratios and calculate four mean errors, correlation coefficients and directional mean accuracy. Last, the authors recommend testing the proposed filtering-combination approach for additional complicated financial time series data in the future to achieve highly accurate, efficient and consistent forecasts.

Fake face identity is a serious, potentially fatal issue that affects every industry from the banking and finance industry to the military and mission-critical applications. This is where the proposed system offers artificial intelligence (AI)-based supported fake face detection. The models were trained on an extensive dataset of real and fake face images, incorporating steps like sampling, preprocessing, pooling, normalization, vectorization, batch processing and model training, testing-, and classification via output activation. The proposed work performs the comparative analysis of the three fusion models, which can be integrated with Generative Adversarial Networks (GAN) based on the performance evaluation. The Model-3, which contains the combination of DenseNet-201+ResNet-102+Xception, offers the highest accuracy of 0.9797, and the Model-2 with the combination of DenseNet-201+ResNet-50+Inception V3 offers the lowest loss value of 0.1146; both are suitable for the GAN integration. Additionally, the Model-1 performs admirably, with an accuracy of 0.9542 and a loss value of 0.1416. A second dataset was also tested where the proposed Model-3 provided maximum accuracy of 86.42% with a minimum loss of 0.4054.

Authors: Shao Liangjing , Chen Benshuang , Zhang Ziqun , Zhang Zhen , Chen Xinrong
Published: January 2024

Recently, artificial intelligence generated content (AIGC) has been receiving increased attention and is growing exponentially. AIGC is generated based on the intentional information extracted from human-provided instructions by generative artificial intelligence (AI) models. AIGC quickly and automatically generates large amounts of high-quality content. Currently, there is a shortage of medical resources and complex medical procedures in medicine. Due to its characteristics, AIGC can help alleviate these problems. As a result, the application of AIGC in medicine has gained increased attention in recent years. Therefore, this paper provides a comprehensive review on the recent state of studies involving AIGC in medicine. First, we present an overview of AIGC. Furthermore, based on recent studies, the application of AIGC in medicine is reviewed from two aspects: medical image processing and medical text generation. The basic generative AI models, tasks, target organs, datasets and contribution of studies are considered and summarized. Finally, we also discuss the limitations and challenges faced by AIGC and propose possible solutions with relevant studies. We hope this review can help readers understand the potential of AIGC in medicine and obtain some innovative ideas in this field.

This study is concerned with the characterization of iron nuggets obtained from the reduction of an iron oxide concentrate in a microwave oven using a biomass-based reducing agent. In the experiments, the concentrate of iron ore consisting of hematite and magnetite minerals supplied from Elazig region and containing 67.29% Fe after enrichment, and as a reducing agent, tea plant wastes containing 94.68% C and 0.03% S after carbonization was used. Carbon required for the reduction of iron oxides to iron was stoichiometrically added to the concentrate with a grain size of -45 µm after its basicity ratio was adjusted. The composite pellets produced after the addition of reducing agent and flux (CaO) were subjected to reduction in a household microwave oven at different times. After the process, optimum (Fe3O4+Fe2O3)/C=1/4, basicity ratio (CaO+MgO)/(SiO2+Al2O3) =1.2 results were obtained. It was seen that the metallic part contained 96.6% Fe, 2.4% C after being separated from the slag and that the metallic phase was separated from the slag very easily. As a result of the microstructure investigations, it was found that the product obtained had similar properties to white cast iron properties.

A modified Nzi trap was tested at a residence and at a farm in eastern Ontario, Canada to better capture high-flying tabanids (Diptera) such as Chrysops Meigen. A new upper trap entrance was created to provide a higher and larger opening by reducing the front blue top shelf to half its height. To minimise escape of low-flying tabanids, a vertical inner baffle was added to direct low-flying tabanids up into the cone. Half of the tests of 18 new designs caught 1.5–2.7 times more deer flies than the Nzi trap did, with the other trap designs being as effective as the Nzi trap. The optimal design that maintained equal catches of other biting flies relative to the Nzi trap was one with a phthalogen inner horizontal shelf and a netting inner vertical baffle. This design is defined in the present as the “bi-level Nzi trap.” Chrysops entered the trap mostly through the top (88%; 17 spp.), along with Hybomitra Enderlein (94%; 12 spp.). Tabanus Linnaeus (9 spp.) entered through both entrances. The most abundant Tabanus, T. quinquevittatus Wiedemann, entered mostly through the bottom (70%), whereas Stomoxys calcitrans Linnaeus entered mostly through the top (92%).

Helminth infections are common in animals. However, the impact of a helminth infection on the function of hematopoietic stem cells (HSCs) and other hematopoietic cells has not been comprehensively defined. In this article, we describe the hematopoietic response to infection of mice with Schistosoma mansoni, a parasitic flatworm that causes schistosomiasis. We analyzed the frequency or number of hematopoietic cell types in the bone marrow, spleen, liver, thymus, and blood and observed multiple hematopoietic changes caused by infection. Schistosome infection impaired bone marrow HSC function after serial transplantation. Functional HSCs were present in the infected liver. Infection blocked bone marrow erythropoiesis and augmented spleen erythropoiesis, observations consistent with the anemia and splenomegaly prevalent in schistosomiasis patients. This work defines the hematopoietic response to schistosomiasis, a debilitating disease afflicting more than 200 million people, and identifies impairments in HSC function and erythropoiesis.

We have previously reported that the gut microbiota of healthy infants harbors allergy-protective bacteria taxa that are depleted in infants with cow’s milk allergy (CMA). Few reports have investigated the role of the gut microbiota in promoting allergic responses. In this study we selected a CMA-associated microbiota with increased abundance of Gram-negative bacteria for analysis of its proinflammatory potential. LPS is the major component of the outer membrane of Gram-negative bacteria. Colonization of mice with a global or conditional mutation of the LPS receptor TLR4 with this CMA microbiota induced expression of serum amyloid A1 (Saa1) and other Th17-, B cell–, and Th2-associated genes in the ileal epithelium in a TLR4-dependent manner. In agreement with the gene expression data, mice colonized with the CMA microbiota have expanded populations of Th17 and regulatory T cells and elevated concentrations of fecal IgA. Importantly, we used both antibiotic-treated specific pathogen-free and germ-free rederived mice with a conditional mutation of TLR4 in the CD11c+ compartment to demonstrate that the induction of proinflammatory genes, fecal IgA, and Th17 cells is dependent on TLR4 signaling. Furthermore, metagenomic sequencing revealed that the CMA microbiota has an increased abundance of LPS biosynthesis genes. Taken together, our results show that a microbiota displaying a higher abundance of LPS genes is associated with TLR4-dependent proinflammatory gene expression and a mixed type 2/type 3 response in mice, which may be characteristic of a subset of infants with CMA.

Purpose The locally advanced unresectable intrahepatic cholangiocarcinoma (ICC) has detrimental oncological outcomes. In this study, we aimed to investigate the efficacy of radiotherapy in patients with locally advanced unresectable ICC.Materials and Methods Between 2001 and 2021, 116 patients were identified through medical record who underwent radiotherapy for locally advanced unresectable ICC. The resectability of ICC is determined by the multidisciplinary team at each institution. Overall survival (OS) were analyzed using the Kaplan-Meier method, and prognostic factors were analyzed using the Cox proportional hazards model.Results The median equivalent radiotherapy dose in 2 Gy fractions (EQD2) was 52 Gy (range, 30 to 110 Gy). Forty-seven patients (40.5%) received sequential gemcitabine-cisplatin based chemotherapy (GEM-CIS CTx). Multivariate analysis identified two risk factors, EQD2 of ≥ 60 Gy and application of sequential GEM-CIS CTx for OS. Patients were grouped by these two risk factors: group 1, EQD2 ≥ 60 Gy with sequential GEM-CIS CTx (n=25); group 2, EQD2 < 60 Gy with sequential GEM-CIS CTx or fluoropyrimidine-based concurrent chemoradiotherapy (n=70); and group 3, radiotherapy alone (n=21). Curative resection was more frequently undergone in group 1 than in groups 2 or 3 (28% vs. 8.6% vs. 0%, respectively). Consequently, OS was significantly better in group 1 than in groups 2 and 3 (p < 0.05).Conclusion Combined high-dose radiotherapy with sequential GEM-CIS CTx improved oncologic outcomes in patients with locally advanced unresectable ICC. Further prospective studies are required to validate these findings.
La gourmandise et autres « transgressions minuscules ». Le péché dans le vocabulaire culinaire de Philippe Delerm

Gourmandise and other “minor transgressions”. Sin in Philippe Delerm’s culinary vocabulary

Philippe Delerm’s prose extols the joy that comes from contemplating everyday life. Experienced intensely, it is a source of pleasure and happiness. The pleasures of food are a theme particularly exploited in this writer’s novels. The approach taken in this article is onomasiological in nature. Its aim is to analyse the lexical units that fall within the conceptual field of the term sin, while referring to different types of food and the sensations associated with its consumption. The occurrences have been systematized according to the list of the seven deadly sins established by Evagrius Ponticus.
Les spécialités culinaires lyonnaises – du culturème gastronomique local au culturème gastronomique national

The culinary specialties of Lyon – from the local gastronomic cultureme to the national gastronomic cultureme

The article deals with the question of Lyon specialties as French “gastronomic culturemes”, as well as with the presentation and definition of Lyonnais dishes offered in typical restaurants, known as “Bouchons Lyonnais”. Each culinary specialty name carries a story and expresses a tradition: local, regional or national. We are going to ponder about the context in which Lyon culturemes with a culinary connotation appeared, about the evolution of the terms in use, and finally, about their presence, throughout history, in the French cultural landscape.
Polityka edukacyjna Unii Europejskiej - zarys problemu
Authors: Szewior Krzysztof
Published: January 2024

Problemem badawczym jest polityka edukacyjna Unii Europejskiej. Artykuł szuka odpowiedzi na pytanie, czy UE prowadzi własną politykę edukacyjną, a jeśli tak, to w czym się ona wyraża. Inną grupą zagadnień jest relacja polityki edukacyjnej państw narodowych wobec działań podejmowanych przez instytucje UE. Kolejny obszar analizy odnosi się do problemów szczegółowych i inicjatyw politycznych UE w edukacji i kształceniu, a odnoszących się do przemian społeczno-gopodarczych i procesów europeizacji. Podstawą metodologiczną jest desk research, analiza instytucjonalna i zawartości dokumentów/aktów prawnych UE, a także kontekst polityk publicznych. Praca wykorzystuje pojęcia nauk o polityce i studiów europejskich, polityki publicznej – polityki edukacyjnej. Głównym wnioskiem z badań jest stwierdzenie, że UE prowadzi własną politykę edukacyjną, która koncentruje się na celach i wartościach społeczno-politycznych oraz na transformacji ekologicznej i technologicznej.
Edukacja obywatelska w systemie szkolnictwa włoskiego
Authors: Kamińska Agnieszka Gloria
Published: January 2024

W Republice Włoskiej zarządzanie systemem oświaty zostało podzielone pomiędzy Ministerstwo Edukacji, Szkolnictwa Wyższego i Nauki i jego delegatury w dwudziestu włoskich regionach, a ponadto – częściowo – przez władze regionów, 94 prowincji oraz gmin (o wysoce zróżnicowanym potencjale demograficznym i gospodarczym). Konstytucja Republiki Włoskiej z 1947 r. w art. 34 zobowiązuje władze państwowe oraz regionalne i lokalne (w prowincjach i gminach) do zapewnienia równego dostępu do szkół. Prawo włoskie ustanawia obowiązek szkolny w wymiarze co najmniej ośmiu lat nauczania. Gwarantuje w tym zakresie bezpłatne nauczanie na poziomie podstawowym i ponadpodstawowym. Nakazuje zarazem usunięcie praktyk dyskryminujących. Zdolnej młodzieży ustawy gwarantują wsparcie finansowe i rzeczowe w dostępie do instytucji edukacyjnych do poziomu uczelni wyższych włącznie. Gwarancja ta jest realizowana przez system stypendiów i zasiłków, w czym partycypować mogą też regiony oraz społeczności (i władze) lokalne.

Od roku 2019 w szkołach włoskich, po latach zmiennej uprzednio praktyki, elementem obowiązkowego nauczania jest z mocy ustawy edukacja obywatelska prowadzona w wymiarze co najmniej 33 godzin w danym roku szkolnym. Program tego wyodrębnionego przedmiotu obejmuje cztery główne segmenty tematyczne: a) wiedzę o prawach i obowiązkach człowieka i obywatela, b) wiedzę o instytucjach władzy publicznej na poziomie ogólnopaństwowym, regionalnym i lokalnym, c) wiedzę o środowisku naturalnym i instrumentach jego ochrony, d) wiedzę o instytucjach Unii Europejskiej i o uprawnieniach wynikających z jednolitego obywatelstwa europejskiego. Edukacja obywatelska jako wyodrębniony i poddany ocenom efektów nauczania przedmiot prowadzona być winna we wszystkich szkołach publicznych oraz w obu występujących we Włoszech typach szkół niepublicznych (przy pewnej ich autonomii co do metod nauczania i sekwencji jego treści).
