PECULIARITIES OF THE PROPAGANDA TRANSFORMATION AS AN INSTRUMENT OF INFLUENCE IN THE METAMODERN SOCIETY

The article reveals the substantive characteristics of the transformation of propaganda as an instrument of influence, and also shows its both destructive and constructive role in the metamodern society. The importance of considering propaganda in a neutral context is determined, which allows us to describe it as an important form of directed communications aimed at changing public opinion in favor of a specific task or intention. The author reveals the positive function of propaganda as a technique of social unification, strengthening faith and ensuring social harmony. At the same time, its destructive potential as a means of manipulation and disinformation is revealed. The stages of transformation of the content, methods and forms of propaganda from antiquity to the present are described. The influence of communication means on the nature of propaganda is shown. If in the twentieth century the main instruments of propaganda were radio, cinema and television, in the twenty-first century they have become social networks. The article identifies the peculiarities of propaganda in the metamodern society, which is characterized by indirect methods of influence based on the mechanisms of seduction and soft power and includes appeals to either rational interests or irrational needs for spectacular or emotional communication. The deterritorialization of ideas and narratives in the modern digital environment creates favorable conditions for concealing propaganda and promoting it more quickly. The author identifies such mechanisms of modern propaganda as temptation, performance, reformatting of contexts, false intertextuality, and personalization of messages. While classical propaganda was vertical in nature, in the metamodern society, horizontal ties through which propaganda narratives are promoted are becoming more important. The increasing dependence of the authorities on the desires of citizens in modern democracies causes propaganda to be built on the basis of public expectations, which leads to the prevalence of populism in political decisions. The author describes the phenomenon of post-truth as a product of modern propaganda, which shapes public opinion not by using facts but by relying on emotional reactions of people. The author proves the importance of controlling the methods and strategies of propaganda in the metamodern society.

Quo vadis, OHADA Private International Law?

Abstract Twenty-eight years after the creation of the Organization for the Harmonization of Business Law in Africa (OHADA), private international law remains a “Cinderella subject” in western and central Africa. Indeed, there are no coherent sets of rules regarding the law applicable to contractual obligations, international jurisdiction, as well as the recognition and enforcement of foreign judgments under OHADA law. This article contends that the main reason behind the lesser importance given to private international law in the OHADA region can be found in OHADA’s unification technique itself: OHADA unifies (and does not merely harmonize) business law. Its Uniform Acts are directly applicable and overriding in all the Member States; therefore, one could (erroneously) think that courts would never have to grapple with difficult questions as to which Member State’s law would apply to a dispute falling within the scope of a Uniform Act, as the laws of all the Member States would yield the same results. This article demonstrates that the Uniform Acts are incomplete either because they contain gaps or because they sometimes refer to the national legislations of the Member States. Thus, the unification of the substantive rules does not eliminate the need for the existence and the unification of conflict-of-laws rules. Moreover, this article provides a tour d’horizon of the existing seldom private international law rules under OHADA law. Additionally, it suggests new avenues for the development of a future OHADA legislation on the law applicable to contractual obligations, international jurisdiction, as well as the recognition and enforcement of foreign judgments.

Portal vein reconstruction using side-to-side unification technique for infant-to-infant deceased donor whole liver transplantation.

Backgrounds/AimsInfant-to-infant whole liver transplantation (I2I-WLT) has been rarely performed in Korea. We analyze clinical sequences of our 7 cases of I2I-WLT and present evolution of surgical techniques to prevent PV stenosis.MethodsA total of 7 cases of I2I-WLT were performed at our institution during last 13 years, which represented 0.1% of our LT volume. Patient perioperative profiles and clinical sequences were analyzed with focusing on portal vein (PV) complications.ResultsDonor ages were 6-17 months and graft weights were 140-525 g. Recipient ages were 7-16 months and body weights were 6-10.1 kg and Primary diagnoses were biliary atresia in 6 and progressive familial intrahepatic cholestasis in 1. The first case underwent PV stenting 2 months after I2I-WLT, and underwent retransplantation 6 years later. The second case underwent intraoperative PV stenting, but died 32 days later. The third case underwent repeated PV dilatation. The fourth, fifth and seventh cases experienced no surgical complications, and PV reconstruction was performed using a side-to-side unification venoplasty technique. The sixth case had poor development of the PV system, so customized PV venoplasty was performed, but PV occlusion requiring PV stenting occurred. Early retransplantation was performed, but scanty PV flow was detected despite no obvious PV stenosis, resulting in graft failure. Serious PV complications developed in 4, but none experienced after adoption of side-to-side unification venoplasty.ConclusionsAs PV size in infant donors and recipients is very small, PV reconstruction in I2I-WLT requires specialized surgical techniques of side-to-side unification venoplasty.

A novel hyper-chaotic image encryption with sparse-representation based compression

This digital era uses lots of images in communication, which are confidential and large in volume. The transmission channel thus arises the question of security as well as transmission load. To date, several works are there to solve this issue. However, they fail to provide a single unit that gives these two facilities in a unified way. This paper presents a novel technique of unification of image compression and encryption in a single module via sparse-representation of image frames and hyper-chaotic encryption techniques. In this work, we have proposed a method to estimates the sparse vectors of a given image using a regularized trained over-complete dictionary and encrypt the non-zero coefficients of the sparse vectors using key-streams generated by a hyper-chaotic system. This sparse coding based encryption technique provides a higher compression ratio (CR) compared to some recently proposed techniques on one side and increases security level on the other side. Moreover, the security is strengthened by using this key-sequence in different steps in the encryption scheme. Thus the compressed-encrypted outputs are stronger than simple chaotic encryption against any intruder. The efficiency and authenticity of the proposed algorithm are verified through several quality-index e.g. entropy, CR, etc. The resistivity of the proposed algorithm toward the known or chosen-plaintext attack is also analyzed. The results of the key sensitivity test, and cropping attack test also ensure the authors’ claim. The comparison of the proposed technique with some recently published works justifies the reliability of this work.

On Solving Nominal Disunification Constraints

This paper proposes an extension of first-order disunification problems by taking into account binding operators according to the nominal approach. In this approach, bindings are implemented through atom abstraction, and renaming of atoms is implemented via atom permutations. In the nominal setting, unification problems consist of equational questions (s≈α?t) considered under freshness constraints (a#?t) that restrict solutions by forbidding free occurrences of atoms in the instantiation of variables. In addition to equational and freshness constraints, nominal disunification problems include also nominal disunification constraints (s≉α?t), and their solutions consist of a substitution and additional freshness constraints such that under these constraints the instantiation of the equations, disequations and freshness constraints with the substitution hold. By re-using nominal unification techniques, this paper shows how to decide whether two nominal terms can be made different modulo α-equivalence. This is done by extending previous results on first-order disunification, and defining the notion of solutions with exceptions in the nominal syntax. A discussion on the semantics of disunification constraints is also given.

Flow over a non-uniform sheet with non-uniform stretching (shrinking) and porous velocities

Viscous flow over a porous and stretching (shrinking) surface of an arbitrary shape is investigated in this article. New dimensions of the modeled problem are explored through the existing mathematical analogies in such a way that it generalizes the classical simulations. The latest principles provide a framework for unification, and the consolidated approach modifies the classical formulations. A realistic model is presented with new features in order to explain variety of previous observations on the said problems. As a result, new and upgraded version of the problem is appeared for all such models. A set of new, unusual, and generalized transformations is formed for the velocity components and similarity variables. The modified transformations are equipped with generalized stretching (shrinking), porous velocities, and surface geometry. The boundary layer governing equations are reduced into a set of ordinary differential equations (ODEs) by using the unification procedure and technique. The set of ODEs has two unknown functions f and g. The modeled equations have five different parameters, which help us to reduce the problem into all previous formulations. The problem is solved analytically and numerically. The current simulation and its solutions are also compared with existing models for specific value of the parameters, and excellent agreement is found between the solutions.

ГИДРАВЛИЧЕСКИЕ ЭКСКАВАТОРЫ И КРАНЫ С МОДУЛЬНЫМИ МЕХАНИЗМАМИ ПРИВОДА

The problem of limiting the standard-size range of drive mechanisms for hydraulic excavators and self-propelled jib cranes with a wide unification of their elements is considered. This approach allows to increase the serialization of products to reduce costs in the design and production, increases the durability of machines and reduces the time of development of new equipment.The analysis of the production of domestic excavators and cranes is carried out. It is presented in a tabular version and a sequence of logical steps to provide a systematic approach to the development of rational designs of hydraulic excavators and cranes. The analysis showed that it is advisable to carry out unification on the modular principle of the formation of some units and, first of all, of slewing mechanisms of these machines. The technique of unification of turning mechanisms and winches of excavators and cranes based on unified planetary hydromechanical block modules is proposed. Creating hydraulic excavators and cranes with unified planetary hydromechanical mechanisms allows you to reduce operating costs and improve the quality of drive mechanisms for excavators and cranes, reducing the cost and complexity of manufacturing. Unification on a modular principle and the subsequent cooperation of parts, assemblies and units allows expanding opportunities to increase production volumes, provides interspecific unification of their basic elements.

Refined surgical techniques to improve the patency of cryopreserved iliac artery homografts for middle hepatic vein reconstruction during living donor liver transplantation.

PurposeA cryopreserved iliac artery homograft (IAH) has not been considered suitable for middle hepatic vein (MHV) reconstruction during living donor liver transplantation (LDLT), primarily due to the low patency from its small diameter. We revised our surgical techniques for MHV reconstruction using an IAH to improve its patency.MethodsThis study analyzed the causes of early conduit occlusion and developed revised techniques to address this that had clinical application.ResultsThe potential risk factors for early conduit occlusion were the small IAH size, small graft in the segment V vein (V5) and segment VIII vein (V8) opening, and small recipient MHV-left hepatic vein stump. These factors were reflected to our revised surgical methods which included endarterectomy of the atherosclerotic plaque, unification of the internal and external iliac artery branches for large V5, and branch-patch arterioplasty for large V8. IAH endarterectomy, branch unification technique, and branch-patch arterioplasty were applied to 8, 5, and 5 patients, respectively and resulted in 1-month occlusion rates of 37.5%, 20.0%, and 40.0%, respectively. The overall patency rates of the IAH-MHV conduits in our 18 patients were 66.7% at 1 month, 38.9% at 3 months, and 33.3% at 1 year.ConclusionOur refined MHV reconstruction using an IAH improved short-term MHV conduit patency, but did not effectively prevent early conduit occlusion, particularly with a small- or medium-sized IAH. Individualized reconstruction designs during LDLT operation are needed when an IAH is used for a modified right liver graft.

Block Unification Scheme for Elliptic, Telegraph, and Sine-Gordon Partial Differential Equations

In this paper, we use the method of lines to convert elliptic and hyperbolic partial differential equations (PDEs) into systems of boundary value problems and initial value problems in ordinary differential equations (ODEs) by replacing the appropriate derivatives with central difference methods. The resulting system of ODEs is then solved using an extended block Numerov-type method (EBNUM) via a block unification technique. The accuracy and speed advantages of the EBNUM over the finite difference method (FDM) are established numerically.

Feature logic for web resources customization: Design and implementation

Users preferences heterogeneity in distributed systems often forces resources suppliers to offer customizable-resources in order to fulfill different customer needs. In this paper we present the formalization and implementation of a Feature Logic based approach that allows customizable-resources description, selection, and composition. In our approach, resources and requests are both specified in a logical framework by feature terms. The feature terms unification technique allows reasoning on these specifications in order to select and possibly compose the resources that are candidate to satisfy a client request.

Fuzzy unification and first order probabilistic logic

The notion of unification for fuzzy sets in fuzzy logic programming is explored in this article from the standpoint of a theoretical framework based on first-order probabilistic modal logic. The fundamental difference between the latter perspective and other approaches described in the literature lies in the characterization of fuzzy sets, which are construed in the logical framework as derived entities having a probabilistic deep structure. The analysis reveals that a few semantic unification techniques are sound even in this probabilistic approach, provided that some specific conditions are enforced. In addition, the approach helps to clarify some important aspects of the informal interpretation for the unification process, including a rationale for the applicability requisites of computational techniques. In the discussion, the reference model adopted for the notion of fuzzy unification is that of evidential logic programming, that is, the one underlying the programming language FRIL.5 © 2002 Wiley Periodicals, Inc.

Material’s Volumetric-Flow Rate (MVR) as a Unification Parameter in Asphalt Rheology and Quality Control / Quality Assurance Tool for High Temperature Performance Grading

Abstract Rheological data of unmodified and polymer-modified asphalts are conventionally obtained from dynamic mechanical characterization and expressed in terms of sets of curves showing the variation of viscoelastic properties with frequency. Using the conventional melt flow indexer, the material’s volumetric-flow rate MVR (in cm3 / 10 minutes) through a predefined die under conditions of constant temperature and stress when obtained for the same asphalts, shows a direct relationship with the dynamic data. The MVR value helps in unifying the sets of dynamic data curves of |G*|, G” and |G* |/sin δ versus frequency in the case of unmodified asphalts, polymer-modified asphalts and asphalt mastics. The unification technique has a sound theoretical basis and the unified curves have far-reaching implications. Since MVR is so simple to determine quite accurately on a relatively inexpensive, easy-to-use flow measurement device (FMD), this parameter can be generated on paving sites or at refineries, if needed, rather than in research laboratories as is the case with the fundamental rheological parameters. The MVR can then be used as an excellent indicator of the fundamental rheological parameters through the use of the unified curves. The MVR can be utilized to accurately determine the currently used high temperature performance grade specification of paving asphalt. On account of the simplicity in obtaining this specification value from the MVR, it may be routinely used for quality control / quality assurance purposes. It can also be used as a rapid product development / formulation tool.

Validating the generality and predictive ability of unified rheological curves for unmodified paving asphalts

Fundamental rheological properties of unmodified paving asphalts have been shown to form unified curves when the material’s volumetric flow rate MVR (in cm 3/10 min) is used as a normalizing factor. The generality of the unification technique is shown by analyzing rheological data for a wide variety of unmodified core asphalts under different temperature conditions. Based on a broad spectrum of covered data, it is concluded that the unified curves are applicable to all unmodified paving asphalts. The predictive ability of the unified curves is then checked and found to give reasonably reliable information. Thus, using a simple parameter like MVR which is determined quite accurately on a relatively inexpensive, easy-to-use flow measurement device (FMD), all fundamental rheological parameters of unmodified paving asphalts can be calculated from the unified curves without the actual data generation of viscoelastic properties through the dynamic shear rheometer.

A new unified model for submicron MOSFETs

A new unified analytical model for submicron MOSFETs, valid for all regions of operation (including deep subthreshold), is presented in this paper. It accounts for the changes in the subthreshold slope with respect to the applied drain voltage. A new unification technique is proposed, which preserves the continuity of the drain current and its derivatives with respect to the applied terminal voltages at the various operating region boundaries. It passes the benchmark tests of Tsividis and Suyama (IEEE J. Sol. St. Circ., 29 (1994) 210–216) adequately, and thus, is suitable for analog circuit computer-aided design work. Also, the simulated results match well with the experimental results for deep submicron channel length devices.

Stochastic cocycles over ?2-graded*-algebras

The correspondence between fermionic evolution and stochastic cocycles over ℤ2-graded von Neumann*-algebras is proved to be parallel to the one in the boson case. To show this, the technique of unification of bosonic and fermionic quantum stochastic calculus is applied.

Towards characterizing quantum stochastic fermionic evolutions

The generalization to the case of Z 2-graded von Neumann algebras of evolutions satisfying a quantum stochastic differential equation with bounded coefficients and driven by fermionic noise is presented. It is proved that the correspondence between fermionic evolutions and stochastic cocycles in this case is parallel to the one in the boson case [11]. Use of the unification technique [14] allows us to benefit from working in the boson Fock space.

On phase-locked motions associated with strong resonance

This paper is concerned with the stability and bifurcation behaviour of a nonlinear autonomous system in the vicinity of a compound critical point characterized by two pairs of pure imaginary eigenvalues of the Jacobian. Attention is focused on the local dynamics of the system near-to-resonance. The methodology developed earlier for the bifurcation analysis into periodic and quasi-periodic motions (unification technique coupled with the intrinsic harmonic balancing) is extended to consider the stability and bifurcations of resonant cases. A set of simplified rate equations characterizing the local dynamics of the system is derived. These equations differ from those associated with nonresonant cases in that they are phase-coupled. Furthermore, the stability conditions of the phase-locked periodic bifurcation solutions are presented. All the results are expressed in explicit forms.

Sensitivity analysis of certain dynamic bifurcations

Control systems and other dynamic systems may lose stability at critical points from which bifurcations take place. However, due to the existence of small disturbances or imperfections, the dynamic behaviour of a system—in particular, the stability conditions—may change drastically. This paper is concerned with the imperfection sensitivity of dynamic bifurcations (degenerate or generalized Hopf bifurcations) arising in nonlinear autonomous systems. The analysis is carried out via the unification technique coupled with the intrinsic harmonic balancing procedure. It has been observed that the sensitivity properties associated with dynamic bifurcations are inherently different from those associated with static bifurcations. However, some similarities concerning the sensitivity curves do exist. A nonlinear feedback control system is analyzed to demonstrate the applicability of the analytic results.

An application of program unification to priority queue vectorization

In this experimental study, we apply the technique of program unification to priority queues. We examine the performance of a variety of unified priority queue implementations on a Cray Y-MP. The scope of the study is restricted to determining if different implementations of priority queues exhibit markedly different performance characteristics under program unification. We found this to be true. In a larger view, this result has interesting consequences in the application of program unification to discrete event simulations on vector or SIMD machines. We find the heap to be a promising data structure in the program unification paradigm.
