Exploration and Application of DNA-Binding Proteins to Make a Versatile DNA-Protein Covalent-Linking Patch (D-Pclip): The Case of a Biosensing Element.

DNA-protein complexes are attractive components with broad applications in various research fields, such as DNA aptamer-enzyme complexes as biosensing elements. However, noncovalent DNA-protein complexes often decrease detection sensitivity because they are highly susceptible to environmental conditions. In this study, we developed a versatile DNA-protein covalent-linking patch (D-Pclip) for fabricating covalent and stoichiometric DNA-protein complexes. We comprehensively explored the database to determine the DNA-binding ability of the candidates and selected UdgX as the only uracil-DNA glycosylase known to form covalent bonds with DNA via uracil, with a binding efficiency >90%. We integrated a SpyTag/SpyCatcher protein-coupling system into UdgX to create a universal and convenient D-Pclip. The usability of D-Pclip was shown by preparing a stoichiometric model complex of a hemoglobin (Hb)-binding aptamer and glucose oxidase (GOx) by mixing at 4 °C. The prepared aptamer-GOx complexes detected Hb in a dose-dependent manner within the clinically required detection range in buffer and human serum without any washing procedures. D-Pclip covalently connects any uracil-inserted DNA sequence and any SpyCatcher-fused protein stoichiometrically; therefore, it has a high potential for various applications.

Detecting possible pairs of materials for composites using a material word co-occurrence network.

Composite materials are popular because of their high performance capabilities, but new material development is time-consuming. To accelerate this process, researchers studying material informatics, an academic discipline combining computational science and material science, have developed less time-consuming approaches for predicting possible material combinations. However, these processes remain problematic because some materials are not suited for them. The limitations of specific candidates for new composites may cause potential new material pairs to be overlooked. To solve this problem, we developed a new method to predict possible composite material pairs by considering more materials than previous techniques. We predicted possible material pairs by conducting link predictions of material word co-occurrence networks while assuming that co-occurring material word pairs in scientific papers on composites were reported as composite materials. As a result, we succeeded in predicting the co-occurrence of material words with high specificity. Nodes tended to link to many other words, generating new links in the created co-occurrence material word network; notably, the number of material words co-occurring with graphene increased rapidly. This phenomenon confirmed that graphene is an attractive composite component. We expect our method to contribute to the accelerated development of new composite materials.

Pairing effects on pure rotational energy of nuclei

By applying the angular-momentum projection to the self-consistent axial mean-field solutions with the semi-realistic effective Hamiltonian M3Y-P6, the pairing effects on the pure rotational energy of nuclei, i.e. the rotational energy at a fixed intrinsic state, have been investigated. While it was shown at the Hartree–Fock (HF) level that the individual terms of the Hamiltonian contribute to the rotational energy with ratios insensitive to nuclides except for light or weakly-deformed nuclei, the pair correlations significantly change the contributions, even for the well-deformed heavy nuclei. The contribution of the interaction to the rotational energy is found to correlate well with the degree of proximity between nucleons, which is measured via the expectation value that two nucleons exist at the same position. While the nucleons slightly spread as the angular momentum increases at the HF level, accounting for the positive (negative) contribution of the attractive (repulsive) components of the interaction, the pair correlations reduce or invert the effect.

Spatially-indirect and hybrid exciton–exciton interaction in MoS2 homobilayers

Interlayer excitons in transition-metal dichalcogenide (TMD) bilayers, alongside their interplay with direct excitonic species, are supposed to offer a pathway towards robust nonlinearity, enabling the exploration of many-body quantum effects. We present a theoretical investigation of interaction among various exciton species within these structures where Coulomb attraction and repulsion are subject to reduced screening. For a homobilayer MoS2, we examine both direct, spatially-indirect, and hybridised excitons, considering the effects of direct and exchange interaction of electrons and holes distributed across one or different layers. Similar physics arises in perfectly aligned twisted TMD heterobilayers which support the direct-to-indirect exciton hybridisation. Deriving the exciton–exciton interaction matrix elements, we unveil a distinct non-monotonic dependence of the interaction on transferred momentum, changing sign from repulsive to attractive even for ground-state excitons, and compare our results with existing calculations for monolayers. Our findings demonstrate that for large momenta involved in high-density effects (strongly correlated phases), the interaction is chiefly governed by the prevailing attractive exchange component. At the same time, at small momenta that are more relevant for rarefied systems, we find that the enhancement of the interaction constant for dipolar species compared to intralayer non-dipolar excitons may be hindered by the surrounding medium. We draw comparisons with existing experiments and discuss the implications of our findings on the collective effects in TMD-based systems of excitons and exciton-polaritons.

Elucidating Super-Compressible States in Inner Structure of Vehicular Flow

The article deals with the open questions in the theory of vehicular headway modeling. Specifically, the question of the existence of anomalous constellations in vehicular traffic micro-structure, in which the rate of fluctuations (measured by the stochastic compressibility) exceeds the fluctuation level of systems with non-interacting elements. The solution to this open problem is converted into the mathematical format working with the so-called balance particle systems, where seeking relevant relations is more straightforward and thus significantly easier. Presented research has shown that unit compressibility represents (despite popular opinion) the upper limit only for particle systems, in which there is no attractive interaction between the particles. In the article, the specific system is constructed in which the presence of an attractive force component will cause higher fluctuations than in the Poisson systems of non-interacting elements. This means that traffic constellations with higher compressibility (so-called super-compressible constellations) can be explained either by a discrepancy between the empirical traffic flow and the mathematical model used, or by the presence of attractive forces acting between individual vehicles. Using empirical vehicular data (measured on two parallel freeway lanes under reconstruction), we show that super-compressible states occur even though overtaking is prohibited. This means, therefore, that these super-compressible states arose without a doubt due to the mutual attraction of successive vehicles. In addition, the article shows that the presence of the aforementioned attractive forces appears predominantly in the fast lane, and only in situations where the traffic density is relatively low. At higher densities, the two freeway lanes are markedly synchronized, the opportunity for a sporty style of driving vanishes and the reason for changing lanes disappears. Under these circumstances, the attractive force component vanishes, which finally leads to the transition of the entire traffic system back to standard sub-compressible states.

Use quantum mechanical computational methods to investigate interactions between imidacloprid and boron nitride nanotubes

The study investigates the interaction between a boron nitride nanotube (BNNT) and an imidacloprid (IM) molecule. The structure of the BNNT is detailed, measuring 9.964 Å in diameter and 18.186 Å in length. Six interaction geometries (BNNT_IM_1 to BNNT_IM_6) between BNNT and IM are investigated, with BNNT_IM_6 showing the most thermodynamically stable interaction. The electronic interaction energies are calculated, and BNNT_IM_6 presents the lowest value (−1.89 eV), indicating a favorable interaction. Quantum theory of atoms in molecules (QTAIM) and analysis of noncovalent interactions (NCI) support the findings. BNNT_IM_6, with IM inside the nanotube, shows the highest electron sharing, explaining its superior stability. The chlorine-BNNT interaction was revealed to be a determining attractive component. The attraction/repulsion indices highlight BNNT_IM_1 as having the most attractive interaction, driven mainly by oxygen-BNNT and chlorine-BNNT interactions. The investigation emphasizes the importance of considering multiple factors, including electron density and interaction volume, in evaluating the strength of BNNT-IM interactions. This study model opens a proposal to assess the impact of functional groups, from a physicochemical perspective, of a molecule interacting with a nanotube surface.

Assessment of the level of investment attractiveness of Ukrainian economy using multidimensional average method

In the article it has been estimated the level of investment attractiveness of the Ukrainian economy using multidimensional average method. For this purpose, the structure of national investment attractiveness was identified and five main components that are political, economic, social, scientific, technical, natural and geographical. The political component of national investment attractiveness is characterized by the following indicators: world press freedom index, economic freedom index, political freedom index, and ease of doing business index. The economic component of national investment attractiveness is characterized by the following indicators: GDP per capita, unemployment rate and government debt in GDP. The social component of national investment attractiveness is characterized by the following indicators: literacy rate, Gini coefficient, happiness index. The scientific and technical component of national investment attractiveness is characterized by the following indicators: number of scientists and engineers per million people, number of technological parks in the country, the research and development (R&D) effectiveness index. The natural and geographical components of national investment attractiveness are characterized by the following indicators: size of electricity production, share of renewable resources in region electricity generation, percent of agricultural land in the country. The listed indicators were distributed on stimulants and disincentives and normalized. Results of calculations show that the level of investment attractiveness of the Ukrainian economy is quite low (ICIA = 0.393) and even lower than that in most analyzed countries (by 0.012 compared with Poland, by 0.023 compared with Hungary, by 0.049 compared with Romania, by 0.06 compared with Bulgaria), but it is higher than the level of investment attractiveness of Moldavian economies. The integral coefficient of investment attractiveness in Ukraine is characterized by the highest value of the general coefficient of natural resource component (GCN&G = 0.368). For comparison, in Poland, the value of that indicator equals 0.284, in Slovakia it equals 0.231, in the Czech Republic it equals 0.264. Instead, in accordance with the general coefficients of scientific and technical components, Ukraine is an outsider of Eastern Europe: GCR&D = 0.162 in Ukraine, GCR&D = 0.363 in Moldova, GCR&D = 0.401 in Slovakia, GCR&D = 0.442 in Romania. In addition, general coefficients of economic and social components are quite low (GCE = 0.435 and GСС = 0.412 accordingly) due to several institutional and financial factors, namely imperfect legal framework, low level of trust of major market participants in government, low financial literacy of population, high probability of non-repayment of loans. To raise the investment attractiveness of the Ukrainian economy, it is necessary to create new industries and markets, reform the taxation system, stabilize the banking system, improve the work of insurance companies, create institutions that would be involved in mobilizing investment resources for specific investment projects and programs.

The growth of the cultivation and processing of citrus fruits is accompanied by the formation of a large amount of waste, which contains a number of useful nutrients and can serve as a valuable biological resource for various fields of application. The vitamins, trace elements, dietary fibers present inthe composition allow you to use them as effective functional additives. The specificity of citrus dietary fibers is a large amount of protopectin, which determines their significant sorption properties. The ability of fibers to retain water makes them effective thickeners and attractive components of low-fat emulsion products, such as mayonnaise sauces. The article presents the results of a study of the properties of powders obtained from dried grapefruit and orange peels by grinding and dividing into fractions by sieving through sieves of different diameters. The indicators of the moisture-retaining capacity of grapefruit and orange powders, their blends and mixtures with coconut flour were determined. The stability of low-fat emulsion products obtained with the addition of the indicated additives in the amount of 5% to the recipe was studied.The introduction of grapefruit and orange powder additives into the low-fat mayonnaise sauce recipe will enrich them with dietary fibers, give a piquant taste and aroma, and contribute to the formation of a product with proper rheological properties and consistency.The analysis of research and publications showed that among the hydrocolloids used in the production of low-fat mayonnaise products, a special place is occupied by dietary fibers of citrus fruits with a high index of moisture retention capacity, which is higher than that of fibers from other raw materials, for example, carrots or oats. Considerable attention is paid to orange pulp powder products with a balanced content of soluble and insoluble dietary fibers, which serve as effective additives capable of retaining moisture and forming low-fat products with a thick consistency.The purpose of the article is to study the properties of grapefruit peel powder and its mixtures with other functional additives for low-fat mayonnaise sauces; determination of their moisture retention capacity; production and stability research of low-fat mayonnaise sauces based on them.For different size fractions of dried and crushed grapefruit and orange peel, indicators of moisture retention capacity were determined. It was established that this indicator has a larger value for the smallest fraction. For grapefruit powder with a particle size of less than 0.50 mm, the moisture retention capacity is 808%, and for orange -591%. A mixture of grapefruit and orange powder with different ratios of components was also found to have a high ability to retain water. Properties of mixtures of citrus powder and coconut flour were studied. Made samples of low-fat mayonnaise sauces with the addition of individual and complex functional additives in the amount of 5%.

Clustering Villages in the Mountain Areas in West Java Based on Tourism Potential Using K-Prototype Algorithm

Cluster analysis is a multivariate analysis method used to group objects based on their similar characteristics. In general, in the clustering process only use numerical or categorical data. But, sometimes we also encounter cases that use both numerical and categorical data. Therefore, the algorithm that can be used is K-Prototype. K-Prototype is a development of K-Means that can be used on large data with numerical and categorical types. The basis of K-Prototype development is to measure the distance between the object and its centroid prototype. The number of prototypes depends on the number of clusters formed. In this study, researchers use this algorithm to group mountainous villages in West Java based on their tourism potential, in order to find out the potential that needs to be developed based on five components, namely Attractions, Access, Accommodation, Amenities and Awareness. Based on the Silhouette and McClain Index, the optimal number of clusters is two. Cluster 1 consists of 103 villages and cluster 2 consists of 703 villages. Cluster 1 are villages that are generally better in the Access, Awareness and Amenities, but are still lacking in the Attraction and Accommodation components compared to villages in cluster 2.

Trichological problems at the intersection of dermatology and psychiatry: analysis of opportunities and ways of development

In recent decades of significant development in the world, a new perspective direction of integration of psychosomatic medicine and psychiatry/medical psychology, which is focused on the study of interaction between psyche and skin, is psychodermatology. Among topical psychodermatological problems, special attention is paid to the peculiarities of the psycho-emotional sphere in different types of alopecia, because, even in the light of socio-cultural features, in most societies, hair is an important component of attractiveness, and its pathology can have serious psychological and even psychiatric. Analysis of the state of the problem in this field has proved that the presence of alopecia is a powerful factor that has a negative impact on the mental state and quality of life of the patient. The presence of alopecia is associated with high levels of depression and anxiety, as well as with worse social functioning and lower quality of life. This requires additional research and development of personalized therapeutic and rehabilitation measures for eliminate the negative psychiatric consequences of alopecia

Percepción de la estética dental en adolescentes

Introduction: Facial aesthetics affects not only how people are perceived by society but also how they perceive themselves. The appearance of a person's teeth and smile are the main critical components of facial attractiveness. Objective: To check the perception of adolescents about dental aesthetics using the WHO criteria. Design: Systematic review of studies published from 2002 to 2022. Data sources: PubMed, Eligibility criteria were articles that used: Oral Aesthetics Subjective Impact Scale (OASIS), a visual scale and the Dental Aesthetics Index (DAI).

Metastability of π-π stacking between the closed-shell ions of like charges

Planar cations or anions can form stacks in crystals or solutions, where the surrounding or environment plays a decisive role as demonstrated in previous studies. However, it remains unclear whether these counterintuitive interactions possess any inherent stability or are thoroughly repulsive if the constraint of environment is removed. In this work, we explored the inherent stability of π-π stacking between closed-shell ions of like charges with prototypes derived from experimental studies. The inherent metastability was identified by the characteristic local minima and the transition states preventing their dissociation and verified by ab initio molecular dynamics (AIMD) simulations. The nature of involved interactions was deciphered with the energy decomposition approach based on the block-localized wavefunction method (BLW-ED). Like the conventional neutral π-π stacking interactions, electron correlation is the most attractive energy component. But it is overturned by the Coulombic repulsion between net charges for all modes of dimerization, resulting in the overall repulsive inter-cation or anion interactions. Contributions from van der Waals interactions were also observed in the reduced density gradient analysis. The origin of the metastability was elucidated by examining the contributions of individual physical factors to the well-depths. The inherent metastability originates from the electron correlation, which dramatically increases due to the enhanced overlap between ions from a transition state to its corresponding minimum.

IMPROVING THE APPROACH TO ASSESSING THE ECONOMIC SUSTAINABILITY OF REGIONAL ENTERPRISES

The results of the analysis of existing approaches to the selection of indicators and criteria for assessing the economic sustainability of regional enterprises show that a large number of different indicator systems are used. However, none of the approaches takes into account the innovation component, despite the growing role of the scientific and technical factor in the activities of regional enterprises. It is proved that the innovative attractiveness of enterprises is an important component of investment attractiveness, since investors associate the prospects of investment with innovations and invest in economically sustainable enterprises. Accordingly, the paper considers the innovation attractiveness of regional enterprises from the perspective of ensuring economic sustainability and defines it, unlike existing approaches, as the ability of an economic entity to ensure and maintain a high level of innovation activity over time. This approach involves the development of an innovation strategy and the implementation of innovative projects, contributes to building up the innovation potential, ensures and maintains high efficiency of innovation activities. To analyze the innovation attractiveness of enterprises, the economic sustainability of activities is structured by the following components – financial, social, production and technical, marketing, innovation, and indicators for their evaluation are proposed. It is proved that the number of indicators required to assess the innovation potential that can ensure the economic sustainability of enterprise activity should be limited by their practical applicability, the cost of development and obtaining information. The allocation of the innovation component ensures not only the fulfillment of complex production tasks in a changing environment of functioning of regional enterprises, but also contributes to the overcoming of the economic crisis with minimal consequences for them, since innovative solutions contribute to the optimization of production and use of resources, provide flexibility in terms of the realities of doing business. The proposed set of quantitative indicators, calculated on the basis of financial and statistical reporting data, allows to determine the economic sustainability of regional enterprises, taking into account their innovative attractiveness.
