On the theory of Uda-Yagi type antenna

Field: Engineering (Physical Sciences)

For Uda-Yagi type antenna the system of integral equations, where the unknown functions are the axial currents arising at antenna dipoles, is received in strict mathematical approach. The method of delta-like generalized function is used, and this system reduces to the system of functional (summatory) equations relative to Fourierpsilas coefficients of the axial currents. The solution of this system makes possible to determine the values of given currents and, based on it, to calculate the radiation characteristic of the antenna For the definite situations the numerous results are presented.
Multiagent framework for lean manufacturing

Field: Computer Science (Physical Sciences)

We have developed the manufacturing agent-based emulation system as an open framework for design and analysis of discrete manufacturing systems. MABES currently supports the transition from traditional to lean manufacturing in two major functions: analysis of alternative agent-based scheduling and control approaches that can be implemented across the extended enterprise; and real-time collaboration of design teams during manufacturing line design and analysis stages. MABES bases its support for these functions on two system paradigms: distributed agents and synchronous collaboration.
Nutrition Label Accuracy And The Theory Of Triadic Influence: The Impact Of Knowledge On Healthy Food Choices In A Predominantly Hispanic Sample

Field: Psychology (Social Sciences)

Unhealthy food choices and the outcomes of those choices are a significant concern in the United States. Multiple governmental agencies recommend using nutrition labels to promote healthier food choices. This study investigated this claim using the theory of triadic influence to examine the efficacious use of nutrition labels on food choices. The theory of triadic influence presents a model of variables that affect food choice, including knowledge pathways on which this study focuses. Within the model, we expected increased scores on two measures of health knowledge to predict nutrition label understanding, which predict healthy food attitudes. Next, we expected that healthier attitudes would predict healthy eating intention, which we anticipated would increase the likelihood of participants to select a healthier food option when participants were presented with two nutrition bars. The study tested the theory using a path model to predict a hypothetical food choice with 612 primarily Hispanic students at the University of Texas at El Paso in 2017. The hypotheses were partially supported. First, we found statistically significant results for both health literacy (Î² = 0.47; SE = 0.04) and nutrition knowledge (Î² = 0.12; SE = 0.04) predicting label understanding. Second, we found statistically significant results for healthy attitudes predicting healthy intention (Î² = 0.31; SE = 0.03). However, we did not find support for the relationship between healthy intention and hypothetical food choice. These findings provide partial support for the theory of triadic influence. We recommend future studies continue to examine the knowledge pathway of the theory of triadic influence, such as using culturally relevant variables related to health knowledge and asking about respondents' frequency of using nutrition labels.
Some Observations on Technology Transfer in Japan

Field: Business, Management and Accounting (Social Sciences)

Abstract : The report draws upon existing literature from Japanese and non- Japanese authors to provide a brief overview of the Japanese technology transfer mechanism. It stresses the totality of that country's commitment to economic growth utilizing the technology transfer tool as a major contributor toward this end. The technical aspects are considered, along with the various secular factors--financial, political, economic, social, cultural--that provide the support upon which the Japanese technology transfer success is based. To a limited extent, the uniqueness and universality of this Japanese experience are discussed.
Development of a Graded Early Warning Index System and Identification of Critical Temperatures for Coal Spontaneous Combustion Using Composite Gas Characteristics

Field: Environmental Science (Physical Sciences)

Conventional single gas alarm method and coal spontaneous combustion three-stage alarm method have become increasingly inadequate to meet complex underground conditions. To address this issue, this study focuses on the coal in the goaf of the Z109 working face in the Donggucheng Mine as the research object. Through program-controlled heating experiments, the production of carbon monoxide and hydrocarbon gases during the coal oxidation process was determined, and the variation characteristics of gas ratios with temperature were further analyzed. The coal spontaneous combustion process was subdivided into seven small stages, and a quantitative composite parameter coal spontaneous combustion grading warning system was formulated. Based on its characteristics, measures to be taken under different warning levels were proposed, and it was determined that 120, 140, and 160 °C are the key temperatures for coal spontaneous combustion prevention and control in the Z109 working face of Donggucheng Mine. By using numerical simulation, the optimal nitrogen injection position for the working face was determined and the on-site fire prevention and extinguishing measures were optimized, providing insights into the establishment of a coal mine spontaneous combustion warning system.
Public debt improves the stability of exchange rates in developing countries? The specific case of news European members (2004 and 2007)

Field: Economics, Econometrics and Finance (Social Sciences)

The aim of this paper is to speak about the current situation in Central and Eastern European countries (CEEC). The majority of them have been entering in European Union in 2004 and 2007. This step has been increasing their international attractiveness and improves their economic growth. However, they must stabilize exchange rate to sustain their foreign direct investment attraction. Two strategies are adopting about the regulation of exchange rate. Bulgarian, Estonia, Latvia, Lithuania Slovenia and Slovakia are entering in Exchange Rate Mechanism 2 (ERM2) to adopt quickly euro currency (it is now the case for Slovenia in 2007, Slovakia in 2009 and Estonia in 2011). Hungary, Poland, Czech Republic and Romania prefer only to stabilize their currency for the moment. Despite the strong economic dynamic of these countries before the Subprime crisis, the impact reveals the incapacity for several of them to improve currencies stabilities. The theoretical approach about Mundell-Fleming trilemma informs the necessity to scarify monetary policy in a context of free financial market and fixed exchange rate. In a reality, the capacity to use fiscal policy appears supplementary indeed more efficient.

Density of hydrobiont populations in the coastal zone of the Barents Sea and in aquaculture

Field: Agricultural and Biological Sciences (Life Sciences)

Objects for obtaining additional food sources and maintaining the quality of the environment in multicultural farms of the northern seas can be kelp ( Laminaria saccharina ), sea urchin ( Strongylocentrotus droebachiensis ), mussel ( Mytilus edulis ), which do not require significant costs during cultivation. The aim of the study was to assess the productive potential of species promising for multiculture based on the density of their populations. The work is based on the materials of expeditionary research of marine communities of the Barents Sea and on the analysis of scientific and practical developments on the cultivation of aquatic organisms in the reservoirs of the High North. Kelp and mussels are characterized by a wide range of variation density and biomass, and individual characteristics. On the Murman coast, in natural kelp beds, the average biomass is 1.4–5.4 kg/m 2 (up to 16 kg/m 2 ), and the average density is 9–104 specimens/m 2 (up to 172 specimens/m 2 ), significantly varying depending on the local conditions of the biotope. The largest biomass values are characteristic of the mussel population at the Kola Bay mouth (4.8–17.8 kg/m 2 ), and the highest population density was noted in the bays of the Eastern Murman (45030–61167 specimens/m 2 ). Mussels with the largest size and weight (from the studied areas) were found in the Pechenga Bay (shell height 4.3±0.1 cm, mussel weight 6.84±0.34 g). The population density parameters of cultivated species in marine benthic communities, which affect the growth of aquatic organisms, can be recommended for use in multicultural farms of kelp, mussels and sea urchins.

Field: Arts and Humanities (Social Sciences)

The aim of this article is to analyse the concept of social rehabilitation developed by Natalia Han-Ilgiewicz, who went down in the history of Polish science as an outstanding and special educator. Her achievements are cited not only by educators: Researchers in juvenile criminology, child psychology and psychiatry also refer to her research in the area of the social maladjustment/derailment of children and adolescents. She was a brilliant methodologist of revalidation work, a talented writer and academic teacher. The article is based on the method of content analysis. Based on selected sources from the literature on the subject, the author explores the concept of social rehabilitation described and practised by Natalia Han-Ilgiewicz and determines its meaning in contemporary social rehabilitation pedagogy.
Universals

Field: Arts and Humanities (Social Sciences)

It seems that the medieval debate on universals has no direct relevance for current philosophical interests and that it must be seen, at best, as an intriguing patchwork of pre-modern curiosities. This article examines the matter, and defends the moderately “continuistic” idea that the appellation “the problem of universals” is not equivocal when applied to the set questions at issue under that name in medieval and in contemporary analytical philosophy. First, it presents the case for discontinuism, and then explains what might be the root of both the medieval and the contemporary “problem of universals.” The article also argues that the main dividing line with respect to this problem runs between realism and nominalism, taken in today's sense. Finally, it outlines one of the most salient medieval approaches to the problem of universals: William of Ockham's nominalism.
EFFECTS OF CHITOSAN/PROCYANIDIN BASED COATINGS ON QUALITY OF FRESH BLUEBERRIES DURING STORAGE

Field: Agricultural and Biological Sciences (Life Sciences)

Introduction. Blueberries are known to be rich in bioactive compounds, including flavonoids, anthocyanins and phenolic acids. Neverthless fresh berry fruit deteriorates rapidly due to water loss, mold growth (?) and ripe decay (1). Edible coatings were used as an alternative way of preservation because of their ability to reduce moisture loss, solute migration, respiration and transpiration rate, to maintain firmness and generally delay senescence (2). Many studies have investigated the effects of chitosan coatings on the quality, safety and antioxidant activity of fruits. .The aim of this work was to evaluate the efficacy of an innovative edible coating, based on chitosan from mushrooms and procyanidins exract from grape seeds, on fresh blueberry quality maintenance. Materials and Methods. Two different coating solutions were prepared, each of them contained 1.5 % (w/w) of glycerol, 0.20% (w/w) of Tween® 20 and 1% (w/w) of lactic acid, solved in distilled water. In the first solution, chitosan from mushroom was added in a quantity of 1% (w/w); the second coating solution was prepared by combining chitosan from mushroom (1% w/w) and procyanidins extract from grape seeds (0.8% w/w). Whole blueberry fruit were dipped in the coating solutions, in two steps, blueberries dipped in distilled water with the same procedure were used as control. After a dehydration period of 90 min at 25° C coated berry samples were placed in plastic trays (PET) closed in micro- perforated bags (PLA) and stored at 4°C for 14 days. On coated blueberry fruits some chemico-phisical characteristics (weight loss, pH, dry matter, colour and firmness), antioxidant activity (ABTS method) and microbial growth were evaluated at 0, 2, 4, 6, 10, 14 days of storage. Results. For weight loss, pH and dry matter no differences were detected, among the control and the differently coated berry samples at each considered storage time. Both coating types induced a general lower lightness and a more blue colour in blueberry samples as compared with control one. Chitosan and chitosan + procyanidins coatings better maintained berry fruits firmness as compared to control ones until 14 days of storage. As expected the use of coating caused a slight increase in the antiradical activity that was the highest in blueberries coated with chitosan + procyanidins. Microbiological analysis results indicate that all the considered samples resulted below the spoilage threshold for total mesophilic bacteria, yeasts, molds, lactic acid bacteria and total coliforms, during the whole period of storage. Conclusions. The used innovative coatings showed a positive effect mainly on maintaining the firmness and increasing the antioxidant activity of blueberry samples. Results from this study demostrated the efficacy of new type of coating ingredients (chitosan and natural procyanidins) to maintain the overall quality of fresh blueberries during storage.
Crosstalk analysis in quantum networks: detection and localization insights with photon counting OTDR

Field: Computer Science (Physical Sciences)

Leveraging pre-existing classical fiber optic infrastructure, particularly optical fibers, and their associated component technologies, is essential for the practical realization of future quantum networks. However, when adapting such infrastructure for quantum communication, optical crosstalk from sub-milliwatt classical-channel power into quantum channels presents a significant challenge in quantum network development, introducing substantial noise that limits the network's performance, scalability, and fidelity. Crosstalk can occur between fibers at multiple points, such as connector interfaces at patch panels, within optical devices due to inadequate optical isolation, and in other fiber-related components. Crosstalk also occurs between channels with different frequencies within a single optical fiber, as Raman scattering converts classical light to photons at frequencies that may interfere with the quantum signal. While Raman scattering in optical fibers has been widely studied, crosstalk occurring between separate fibers at their connection locations, typically at network components such as transparent switches and patch panels, in quantum networks has not received sufficient attention. Here we report a demonstration using photon-counting optical time-domain reflectometry (ν-OTDR) to precisely identify and localize crosstalk between separate channels within the same fiber and between separate fibers. The coexistence of classical and quantum signals in the same network necessitates the use of optical switches for efficient routing and control. Crosstalk characterization of an optical switch reveals a strong dependence on the cross-connect configuration. Higher crosstalk levels were observed in certain specific configurations, while no measurable crosstalk was detected in others. Additionally, we found that crosstalk exhibits a pronounced wavelength dependence, increasing over tenfold at longer wavelengths. These findings demonstrate the value of ν-OTDR in diagnosing and mitigating crosstalk in quantum networks. They highlight the importance of optimizing optical switch configurations and wavelength management to minimize noise, ultimately enhancing the scalability, fidelity, and overall performance of quantum networks. This work establishes a foundational approach to addressing crosstalk, paving the way for more robust and efficient quantum network designs.

Integrated analysis of DNA methylation profile in HLA-G gene and imaging in coronary heart disease

Field: Medicine (Health Sciences)

Abstract Aims Immune endothelial inflammation, underlie coronary heart disease (CHD) related phenotypes, could provide new insight into the pathobiology of the disease. We investigated DNA methylation level of the unique CpG island of HLA-G gene in CHD patients and evaluated the correlation with cardiac computed tomography angiography (CCTA) features. Methods Thirty-two patients that underwent CCTA for suspected CHD were enrolled for this study. Obstructive CHD group included fourteen patients, in which there was a stenosis greater than or equal to 50% in one or more of the major coronary arteries detected; whereas subjects with Calcium (Ca) Score=0, uninjured coronaries and with no obstructive CHD were considered as control subjects (Ctrls) (n=18). For both groups, DNA methylation profile of the whole 5'UTR-CpG island of HLA-G was measured. The plasma soluble HLA-G (sHLA-G) levels were detected in all subjects by specific ELISA assay. Statistical analysis was performed using R software. Results For the first time, our study reported that 1) a significant hypomethylation characterized three specific fragments (B, C and F) of the 5'UTR-CpG island (p=0.05) of HLA-G gene in CHD patients compared to Ctrl group; 2) hypomethylation level of one specific fragment positively correlated with coronary Ca score, a relevant parameter of CCTA (p&lt;0.05) between two groups. Conclusions Our results showed that reduced levels of circulating HLA-G molecules could derive from epigenetic marks inducing hypomethylation of specific regions into 5'UTR-CpG island of HLA-G gene in CHD patients with obstructive coronary stenosis vs non critical stenosis group.

We present an insertion scheme for semistandard decomposition tableaux and give algorithms of decomposing the tensor product of q(n)-crystals. Consequently, we obtain explicit combinatorial descriptions of the shifted Littlewood-Richardson coefficients.
Monetary policy rules in the pre-EMU era: Is there a common rule?

Field: Economics, Econometrics and Finance (Social Sciences)

Despite the great importance and final success of the convergence process that led to the establishment of the European Monetary Union, there is no clear agreement regarding the monetary policy pursued in the member countries during the convergence process. This paper contributes to the literature with an empirical analysis of the period from 1993 to 1998 that encompasses eleven EMU countries. In particular, Taylor type interest rate rules are estimated with monthly national data to find that, despite certain similarities and exceptions, the rule followed by each country is distinct and differs substantially from the standard Taylor rule. However, for most countries, the parameter estimates reflect the principles proclaimed by the monetary policy authorities and, in addition, it is shown that in most cases the estimated rules reproduce the policy setting quite closely.

Identification and characterization of novel cecropins from the Oxysternon conspicillatum neotropic dung beetle

Field: Biochemistry, Genetics and Molecular Biology (Life Sciences)

Dung beetles are exposed to a complex microbiological ecosystem during their life cycle. Characterization of novel host-defense peptides (HDP) is essential to understanding the host innate immune response in insects. It constitutes a promising alternative to look for new therapeutic agents against pathogenic microbes. We identified four new HDP, Oxysterlins 1, 2, 3, and 4 from the transcriptome of the Oxysternon conspicillatum dung beetle. These HDP display a highly conserved signal peptide and a mature peptide, characterized by an overall positive charge (cationic) (pI: 10.23-11.49), a hydrophobic ratio (ΦH: 35-41), and amphipathicity. Oxysterlins 1, 2, and 3 have a linear α-helix structure, whilst Oxysterlin 4 has a mixture of both α-helix and β-sheet structures without disulfide bonds through bioinformatics prediction and circular dichroism. Oxysterlins are part of the cecropin family group in an exclusive clade related to beetle cecropins. They have predominant antimicrobial activity against Gram-negative bacteria, including multidrug resistant strains (3.12-50 μg/mL) measured by plate microdilution. Their kinetics, in a time-killing curve showed concentration-dependent bactericidal activity. Furthermore, these HDP have low toxicity against human erythrocytes (62.5-500 μg/mL) and Vero cells (250-500 μg/mL). This article describes new HDP of the cecropin family from the Oxysternon conspicillatum dung beetle, with antimicrobial activity against multidrug resistant bacteria and low toxicity.
Ion-beam-spurted dimethyl-sulfate-doped PEDOT:PSS composite-layer-aligning liquid crystal with low residual direct-current voltage

Field: Materials Science (Physical Sciences)

Thin ion-beam (IB)-spurted dimethyl sulfate/poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (DMS/PEDOT:PSS) layers with improved electro-optic performance are presented for aligning liquid crystals. IB spurting is effective for enhancing the conductivity of such layers, as well as the anchoring energy of the liquid crystals sandwiched between them. Compared with a commercial twisted-nematic cell assembled with polyimide alignment layers, the same cell assembled with 3.0-keV IB-spurted DMS/PEDOT:PSS alignment layers shows a 38% faster switching and a 93% lower residual direct current. The improved electro-optic performance here is likely due to the enhanced electric field effect and the charge-releasing ability of thin IB-spurted DMS/PEDOT:PSS layers.
