Managing Data Sovereignty: An Organizational Competence for Successful Open Value Creation

ABSTRACTManaging big data benefits organizations via efficient and effective data‐driven decision making, productivity gains, customization potential, or innovation opportunities. Data‐driven innovation opportunities are particularly valuable in open value creation (OVC), that is, the collaboration of independent stakeholders who open their boundaries to share data and knowledge to jointly create value they could not have achieved in isolation. At the same time, however, incumbents often struggle with the implementation of data sharing in the broader stakeholder ecosystem. In this exploratory study, based on an abductive qualitative study with 27 expert interviews and three industry roundtables with 19 experts, we explore how the concept of organizational data sovereignty could serve as an organizational competency to address the data challenges for OVC. Using the strategy‐as‐practice framework, we define organizational data sovereignty as the self‐determined and intentional exercise of control over an organization's data assets and show which data sovereignty practices, in line with practitioner and praxis conditions, support inter‐organizational sharing and management of big data in OVC. Specifically, we identify key practices for implementing data sovereignty, such as constituting the special value of data and establishing a consistent value assessment for data. When designed and applied in the right organizational framework that allows for openness, agility, and interdisciplinarity, they enable industrial enterprises to realize the potential of OVC.

Contemporary Implication of Marxist Ecological View of Nature

This paper discusses the implication of Marxist ecological view of nature in the contemporary context, analyzes the current situation and challenges of the global ecological crisis, and deeply expounds the theoretical connotation of Marxist ecological view of nature and its response to contemporary problems. With the acceleration of industrialization and the continuous growth of population, the global ecological crisis has become increasingly prominent, which poses a serious threat to the sustainable development of human society. Marxist ecological view of nature emphasizes the dialectical unity of man and nature, the integrity of the ecosystem, and the importance of the construction of ecological civilization. Sex. It holds that the root of the ecological crisis lies in the excessive exploitation and utilization of natural resources by the capitalist mode of production, and that the fundamental way to solve the ecological crisis lies in changing the capitalist mode of production and realizing the ideals of socialism and communism. In contemporary practice, Marxist ecological view of nature provides important theoretical guidance and ideological weapons for countries to deal with ecological and environmental problems. By comparing and analyzing the current situation of international construction of ecological civilization, this paper reveals the uniqueness of Marxist ecological view of nature in the global construction of ecological civilization. Special advantages and value.

MORPHOLOGICAL CHARACTERS IN PROGRESS FOR FIELD PEAS (Pisum sativum L.)

Since ancient times, the field pea has stood out, on the one hand, for its special nutritional value, and, on the other hand, for the favorable impact it leaves on the environment through cultivation. Currently, more and more performing varieties are obtained and with increased adaptability in different environmental conditions. Recently, the plant is also recommended for the establishment of green, protective crops, including in horticulture. It is believed that by growing peas, there is also a conservation of CO2, as a response to the need to reduce the phenomenon of global warming. The new pea variety Avatar thus has a number of improved morphological characters, which proves that pea breeding is making visible progress. Among these new morphological characters, the height of the plant was 80 cm, with the dominant weight of 11 g. The plant had 15 nodes of which the last 6 formed pods. Pod mass was 8 g/plant and contained 22 grains/plant. Pea grains had a mass of 5 g/plant, a diameter of 7 mm, and an absolute mass (BMB) of 260 g. The correlations obtained between these characters showed generally positive trends. Considering the gain of these morphological characters in progress, it is recommended to increase the proportion of the plant in the structure of crops within the farm.

Changes in quality characteristics and inactivation of Salmonella in cake, including oleogel used as a fat replacer, baked with two different methods.

This is the first study to assess the impact of substitution of shortening (50%) with sunflower-beeswax oleogel in cake formulations on the inactivation kinetics of Salmonella spp. and the quality attributes of cakes baked in conventional (CO) and microwave (MWO) ovens. Four distinct cake samples were examined in the study: Cake samples containing oleogel prepared in two different ovens (Oleo-Cake-CO and Oleo-Cake-MWO) and control cake samples baked in two different ovens (Cont-Cake-CO and Cont-Cake-MWO). The control-batter and oleogel-batter demonstrated shear thinning behavior (pseudoplastic, n<1), with a good fit to the Power Law model, but viscosity and viscoelastic moduli decreased when the oleogel was used in place of shortening in cake recipes. In addition, the Cont-Cake-MWO had the greatest special volume value (2.31±0.04mL/g), whereas the Oleo-Cake-CO had the lowest (1.65±0.02mL/g) (p<0.05). Furthermore, compared to the samples baked with CO, lower water activity and moisture values (p<0.05) were observed in the samples baked in MWO due to their higher cooking loss values (p<0.05). In all baking techniques, the addition of oleogel to the cake formula, used as a fat substitute, resulted in higher values for cohesiveness, hardness, springiness, and chewiness (p<0.05). As a result, the inactivation of Salmonella in cakes slightly reduced with using oleogel as a fat substitute (p>0.05), whereas it affected some quality properties of cakes baked with both heat treatments.

On factorization hierarchy of equations for banana Feynman integrals

We present a review of the relations between various equations for maximal cut banana Feynman diagrams, i.e. integrals with propagators substituted with δ-functions. We consider both equal and generic masses. There are three types of equation to consider: those in coordinate space, their Fourier transform and Picard-Fuchs equations originating from the parametric representation. First we review the properties of the corresponding differential operators themselves, mainly their factorization properties at the equal mass locus and their form at special values of the dimension. Then we study the relation between the Fourier transform of the coordinate space equations and the Picard-Fuchs equations and show that they are related by factorization as well. The equations in question are the counterparts of the Virasoro constraints in the much-better studied theory of eigenvalue matrix models and are the first step towards building a full-fledged theory of Feynman integrals, which will reveal their hidden integrable structure.

Ramanujan-Berndt-type integrals of order four and series associated with Jacobi elliptic functions

In this paper, we evaluate in closed forms two families of infinite integrals containing hyperbolic and trigonometric cosine functions in their integrands. We call them Ramanujan-Berndt-type integrals of order four since they initiated the study of similar integrals. We establish explicit evaluations of twelve classes of hyperbolic sums by special values of the Gamma function by two completely different approaches, which extend those sums considered by Xu, Yang, Zhao and the second author previously. We discover the first by refining two results of Ramanujan concerning some q-series. For the second we compare both the Fourier series expansions and the Maclaurin series expansions of a few Jacobi elliptic functions. Furthermore, by contour integrations we convert two families of Ramanujan-Berndt-type integrals of order four to the above hyperbolic sums, all of which can be evaluated in closed forms. We then discover explicit formulas for one of the two families. Moreover, we provide many examples which enable us to formulate a conjectural explicit formula for the other family of the Ramanujan-Berndt-type integrals at the end, and obtain some results on Barnes' multiple zeta function.

On the Finkelberg–Ginzburg Mirabolic Monodromy Conjecture

Abstract We compute the monodromy of the mirabolic $\mathcal{D}$-module for all values of the parameters $(\vartheta ,c)$ in rank 1 and outside an explicit codimension 2 set of values in ranks 2 and higher. This shows in particular that the Finkelberg–Ginzburg conjecture, which is known to hold for generic values of $(\vartheta ,c)$, fails at special values even in rank 1. Our main tools are Opdam’s shift operators and intertwiners for the extended affine Weyl group, which allow for the resolution of resonances outside the codimension two set.

Insights into the Influence of Tensile and Compressive Strain on the Microstructure and Corrosion Performance of 304 L Stainless Steel

The effects of tensile and compressive strain, originating from U-bent deformation, on the corrosion behavior of 304 L stainless steel were studied via analyses of the material’s microstructure and electrochemistry in a 3.5% NaCl solution. In contrast with the as-received 304 L steel with the largest grain size, the deformed 304 L material with a small grain size had the lowest number of Σ3 grain boundaries and an overall low fraction, with special low-Σ values (≤29). Moreover, the dislocation density increased to 1.13 × 1016/m2 and 1.4 × 1016/m2 for the tensile and compressive 304 L steel testing, respectively. The decrease in Epit and increase in ipit suggested that there was a decrease in anti-corrosion properties due to tensile and compressive deformation. This might be attributed to the higher plastic strain found in deformed 304 L steel, which can induce the rupture of passive film and have a harmful influence on corrosion resistance. In particular, the compressive 304 L steel with the highest content of deformed grains (42.12%) promoted the formation of microgalvanic cells, thereby facilitating the nucleation of pits. Then, these pits grew to a large size through grain shedding. Subsequently, massive chloride ions were generated during metal dissolution and diffused along grain boundaries, which promoted the initiation and propagation of intergranular corrosion cracks.

Hilbert Poincaré series and kernels for products of L-functions

We study Hilbert Poincaré series associated to general seed functions and construct Cohen’s kernels and double Eisenstein series as series of Hilbert Poincaré series. Then we calculate the Rankin–Cohen brackets of Hilbert Poincaré series and Hilbert modular forms and extend Zagier’s kernel formula to totally real number fields. Finally, we show that the Rankin–Cohen brackets of two different types of Eisenstein series are special values of double Eisenstein series up to a constant.

Dilatonic dynamics of baryonic crystals, branes, and spheres

We systematically analyze the impact of dilatonic dynamics on Skyrme spheres, crystals, and branes. The effects of the dilatonic model parameters, encompassing different underlying near-conformal dynamics, on the macroscopic properties of skyrmions such as their mass and radius are discussed. For spheres and crystals we identify special values of the ratio of the decay constants for which the second order differential equations reduce to a solvable first order system. Additionally, in the case of the crystals, the dilaton presence spatially separates the baryon and isospin charge distributions. For branes, we show how the dilaton smooths out their configurations. Our results are expected to have wide implications from the study of near-conformal dynamics stemming from QCD-like theories to phenomenological investigations of nuclear matter in extreme regimes.

G. BERKELEY &amp; F. MATHEWS “LOGOS” ONTOLOGY

The purpose of article’s study is to discover Logos phenomenon which is present in the nature of thinking using an empirical method in the value system of F. Mathews &amp; G. Berkeley from the point of view of modern ethics, historical experience, modern psychology and culture of ecology. “Logos” is considered as a segment of the field of thinking, a certain event in the field of meaning.The meaning of “Logos” as an event in the ontology of F. Mathews is considered from a metaphysical point of view and acquires a special semantic value in the context of G. Berkeley philosophy. In the space-time continuum, “Logos” exists in a moving field of meanings and is opposed to “Nonthought.” In the course of history, the manifestation of “Logos” was absorbed by everyday life and mediocrity, but F. Mathews and G. Berkeley are trying to prevent the disappearance of “Logos” by creating an “Ecological Model of Thinking”, revealing perception from internal semantic structures towards natural phenomena. An ecological model of thinking can prevent the formation of a “perceptual dead zone” where human genius is devalued by self-centered mediocrity. The phenomenon of the integrity of the "Logos" is an ethical expression of intuitive perception.The causes and consequences of "ontological inertia" are also revealed.

Construction of electric dyadic Green’s functions in free space based on elliptic cylindrical coordinate system

Abstract A set of vector wave functions is defined in the elliptic cylindrical coordinate system. These vector wave functions can not only describe the propagation characteristics of electromagnetic waves in the elliptic cylindrical coordinate system but also meet the requirements of the electromagnetic field equation. By studying the orthogonality of these vector wave functions, the free space magnetic dyadic Green function is derived by the Ohm-Rayleigh method. The free space electric dyadic Green function is derived from the magnetic dyadic Green function. The special electromagnetic field boundary value problem is transformed into a Green function problem by the electric dyadic Green function. The distribution of the electromagnetic field on the boundary can be obtained by solving the Green function, and then the characteristics of the electromagnetic field can be analyzed. The core of this method is to transform the electromagnetic field problem into a Green function problem, thus simplifying the solving process. This method enriches the electromagnetic field theory and provides a new way to solve the practical electromagnetic field problem.

SPANNING TREES IN $\mathbb {Z}$ -COVERS OF A FINITE GRAPH AND MAHLER MEASURES

Abstract Using the special value at $u=1$ of Artin–Ihara L-functions, we associate to every $\mathbb {Z}$ -cover of a finite connected graph a polynomial, which we call the Ihara polynomial. We show that the number of spanning trees for the finite intermediate graphs of such a cover can be expressed in terms of the Pierce–Lehmer sequence associated to a factor of the Ihara polynomial. This allows us to express the asymptotic growth of the number of spanning trees in terms of the Mahler measure of this polynomial. Specialising to the situation where the base graph is a bouquet or the dumbbell graph gives us back previous results in the literature for circulant and I-graphs (including the generalised Petersen graphs). We also express the p-adic valuation of the number of spanning trees of the finite intermediate graphs in terms of the p-adic Mahler measure of the Ihara polynomial. When applied to a particular $\mathbb {Z}$ -cover, our result gives us back Lengyel’s calculation of the p-adic valuations of Fibonacci numbers.

Fourier coefficients of Jacobi Poincaré series and applications

We define Jacobi Poincaré series over Cayley numbers and explicitly compute its Fourier coefficients. As an application, we obtain an estimate for the Fourier coefficients of a Jacobi cusp form. We also evaluate certain Petersson scalar products involving Jacobi cusp forms and Poincaré series. This evaluation yields certain special values of shifted convolution of Dirichlet series of Rankin-Selberg type associated to Jacobi cusp forms in consideration.

The extended Adomian decomposition method and its application to the rotating shallow water system for the numerical pulsrodon solutions

The rotating shallow water system is an important physical model, which has been widely used in many scientific areas, such as fluids, hydrodynamics, geophysics, oceanic and atmospheric dynamics. In this paper, we extend the application of the Adomian decomposition method from the single equation to the coupled system to investigate the numerical solutions of the rotating shallow water system with an underlying circular paraboloidal basin. By introducing some special initial values, we obtain interesting approximate pulsrodon solutions corresponding to pulsating elliptic warm-core rings, which take the form of realistic series solutions. Numerical results reveal that the numerical pulsrodon solutions can quickly converge to the exact solutions derived by Rogers and An, which fully shows the efficiency and accuracy of the proposed method. Note that the method proposed can be effectively used to construct numerical solutions of many nonlinear mathematical physics equations. The results obtained provide some potential theoretical guidance for experts to study the related phenomena in geography, oceanic and atmospheric science.

Proton Therapy in Uveal Melanoma

Background/Objectives: Uveal melanoma is the most common primary intraocular malignancy in adults. Treatment options for localized, early-stage disease include enucleation, brachytherapy, and proton beam therapy. This review aims to evaluate the role of proton therapy in the definitive management of uveal melanoma, focusing on its physics, radiobiology, treatment techniques, and associated outcomes. Methods: This narrative review synthesizes current literature on proton therapy for uveal melanoma, emphasizing case selection, treatment efficacy, and side effects. Results: Proton therapy offers significant advantages for thicker uveal melanomas (over 8 mm) due to its unique physical properties, including a rapid dose fall-off that protects critical structures like the retina and optic nerve. Proton therapy may have benefits in tumor control for ocular melanomas given its increased relative biological effectiveness relative to photon therapy for these typically more radioresistant melanomas. Proton therapy may also hold special value for uveal melanomas in close proximity to the optic nerve, as patients are at high risk of visual toxicities with brachytherapy. The review discusses the efficacy of proton therapy across small, medium, and large tumors, along with strategies for improving patient survival through combined systemic therapy. Additionally, the potential of ocular reirradiation with proton therapy is addressed. Conclusions: Proton therapy is an effective treatment for uveal melanoma. It offers advantages over brachytherapy for large tumors, tumors that are close to the optic nerve or insertion of extra-ocular muscles.

Effects of Urbanization on Community Composition and Conditions of Birds in Wetland Ecosystems

Urbanization in wetlands has negatively impacted bird species diversity and populations. It is important to be able to predict the consequences for avian biodiversity and to identify wetlands of special value to the maintenance of local wetland communities. This study involved conducting point counts across four permanent urban wetlands at the University of Florida and three retention ponds in the Gainesville, FL vicinity to observe patterns in wetland bird species diversity and populations. This study also utilized data from the Florida Museum of Natural History (FLMNH) to explore differences in phenotypes of wetland bird specimens. The local wetlands showed trends where specific species thrived in one type of area versus the other. Egrets were frequently observed in larger wetlands, and double-crested cormorants were observed more frequently in smaller ones. Additionally, retention ponds showed promise as a conservation method, dependent on their depth and size. The largest retention pond attracted many bird species in great numbers, showing promise for methods to negate negative the impact of human activity and climate change. Characterization for data collected at the FLMNH on both weight and species analyzed across numerous regional locations showed a negative trend between specimen weight and time progression.

Innovative approache for the nonlinear atangana conformable Klein-Gordon equation unveiling traveling wave patterns

The aim of current work is to establish novel traveling wave solutions of the nonlinear Atangana conformable Klein - Gordon equation using a new extended direct algebraic technique. The Klein - Gordon equation is the relativistic state of the Schrödinger equation with a second - order time derivative and zero spin. Complex wave variable transformation is used to convert Atangana conformable nonlinear differential equation into an ordinary differential equation. Using the proposed technique based on Maple software structure, various types of solutions, such as, generalized trigonometric, generalized hyperbolic, and exponential functions, are established. When special parameteric values are considered for this method, solitary wave solutions can be obtained through other methods, such as the (G′G)-expansion method, the modified Kudryashov method, the sub-equation method, and so forth. A physical explanation is provided for the solutions under consideration to enhance comprehension of the physical phenomena resulting from the obtained solutions, provided that the physical parameters are set appropriately using 3D, 2D, and contour simulations. The results demonstrated that the new extended direct algebraic method provides a more potent mathematical tool for solving numerous more nonlinear partial differential equations with the aid of symbolic computation.

THE CONCEPT OF THE SYSTEM OF LEGAL PROTECTION OF OBJECTS WILDLIFE AS A RESULT OF INTELLECTUAL ACTIVITY

The problems of the legal regime of the results of creative activity related to wildlife and humans have acquired special scientific significance and practical value in many countries, including Russia and Kazakhstan. Therefore, research on the development of concepts for the adaptation of the intellectual property law system as a sub-branch of civil law, the definition of the legal regime of new wildlife objects resulting from intellectual activity, and their integration into the already existing legal system, have a strategic level of state tasks aimed at achieving a balance of public and private interests, especially in the field of biomedical technologies and genomic experiments that create very significant risks not only for the living humanity, but also for future generations. Taking into account the above, this article presents the results of a scientific analysis conducted in order to develop a theoretical concept for building a system of legal protection of wildlife objects as the results of intellectual activity and to make proposals for improving legislation in the field of intellectual property law. Based on the results of the study, it is proposed to modernize the system of law in the field of intellectual property in terms of objects of wildlife, including new objects in addition to existing breeding achievements, namely: strains of microorganisms, genetically modified organisms, biomedical cell products, genomes, and other results of intellectual activity created using human and animal biomaterials, including birds, fish and other representatives of fauna, and provide them with an independent legal regime. The revision of the last object "other results ..." allows you to leave the list of wildlife objects open in order, if necessary, to introduce another innovative object into the intellectual property system, providing it with an appropriate legal regime, without additional changes to the law.
