Abstract:

In this paper, using Belarus as an example, we study the mechanisms and conditions for establishing a communication regime, as well as a possible “corridor” for its changes. Based on the analysis of communication channels and the conjugation of communication and institutional approaches, it is shown that communication channels do not arise chaotically, but are regulated by the established configuration of institutions that govern the social system. The intensity of intercountry communications is determined by the institutional affinity of the interacting countries and reaches a maximum in the case of their civilizational unity. The mechanisms and conditions for establishing the communication regime of Belarus are explained by the properties of its institutional matrix, as well as the conditions of existence of society on the line of a civilizational fault. It is shown that the main organizing role in the formation of communication flows in Belarus is assumed by the state, which corresponds to the X (non-Western) type of institutional matrix with the dominance of redistributive institutions and presupposes the presence of a strong branch of government coordinating public activity. The role of religion in the formation of the communication regime is analyzed. It is shown that the communication regime of Belarus is characterized by the presence of two civilizationally divided cores associated with the Eastern and Western Christian churches. The possibility of civilizational changes due to intercountry communications (shifting the border of the civilizational schism from the territory of Belarus to its western borders) and phenomena that hinder them are discussed. The conditions imposed on the “corridor” of changes in the communication regime are defined: achieving a balance of institutional changes initiated “from above” and the readiness to accept these changes “from below”.

Abstract:

In this research, a selective mapping (SLM) technique using the Walsh Hadamard (WH) matrix, the Riemann matrix, and the new enhanced Riemann matrix were introduced to reduce the peak to average power ratio (PAPR) of orthogonal frequency division multiplexing based differential chaos shift keying (OFDM-DCSK). Using a new algorithm to reduce the size of the Riemann matrix, which in turn enhances the computational complexity of the SLM system without affecting the performance of PAPR in the main method. The simulation results show that the SLM technique using the Riemann matrix gives better PAPR performance than WH and conventional techniques by gaining about (6.3, 6.15) dB, respectively, for complementary cumulative distribution function (CCDF)=10-3 and the number of candidates U=16. Also, the results show that the SLM technique based enhanced Riemann matrix gives a reduction in computational complexity by reducing the number of candidates U to 4, while maintaining the same PAPR performance.

Abstract:

Advanced mobile communication systems are characterized by a dense deployment of different types of wireless access points. Since these systems are primarily limited by interference, multiple-input multiple-output (MIMO) techniques as well as coordinated transmission and detection schemes are necessary to mitigate this limitation. Thus, mobile communication systems become more complex which requires that also the mathematical tools for their theoretical analysis must evolve. These must be able to take the most important system characteristics into account, such as fading, path loss, and interference. The aim of this thesis is to develop such tools based on large random matrix theory and to demonstrate their usefulness with the help of several practical applications, such as the performance analysis of network MIMO and large-scale MIMO systems, the design of low-complexity polynomial expansion detectors, and the study of random beamforming techniques as well as multi-hop relay and double-scattering channels. The methods developed in this work provide deterministic approximations of the system performance which become arbitrarily tight in the large system regime with an unlimited number of transmitting and receiving devices. This leads in many cases to simple and close approximations of the finite-size system performance and allows one to draw relevant conclusions about the most significant parameters. One can think of these methods as a way to provide a deterministic abstraction of the physical layer which substantially reduces the system complexity. Due to this complexity reduction, it is possible to carry out a system optimization which would be otherwise intractable.

Abstract:

Cette thèse traite d'une routine d'algèbre linéaire largement utilisée pour la résolution des systèmes li- néaires, il s'agit de la factorisation LU. Habituellement, pour calculer une telle décomposition, on utilise l'élimination de Gauss avec pivotage partiel (GEPP). La stabilité numérique de l'élimination de Gauss avec pivotage partiel est caractérisée par un facteur de croissance qui est reste assez petit en pratique. Toutefois, la version parallèle de cet algorithme ne permet pas d'atteindre les bornes inférieures qui ca- ractérisent le coût de communication pour un algorithme donné. En effet, la factorisation d'un bloc de colonnes constitue un goulot d'étranglement en termes de communication. Pour remédier à ce problème, Grigori et al [60] ont développé une factorisation LU qui minimise la communication(CALU) au prix de quelques calculs redondants. En théorie la borne supérieure du facteur de croissance de CALU est plus grande que celle de l'élimination de Gauss avec pivotage partiel, cependant CALU est stable en pratique. Pour améliorer la borne supérieure du facteur de croissance, nous étudions une nouvelle stra- tégie de pivotage utilisant la factorisation QR avec forte révélation de rang. Ainsi nous développons un nouvel algorithme pour la factorisation LU par blocs. La borne supérieure du facteur de croissance de cet algorithme est plus petite que celle de l'élimination de Gauss avec pivotage partiel. Cette stratégie de pivotage est ensuite combinée avec le pivotage basé sur un tournoi pour produire une factorisation LU qui minimise la communication et qui est plus stable que CALU. Pour les systèmes hiérarchiques, plusieurs niveaux de parallélisme sont disponibles. Cependant, aucune des méthodes précédemment ci- tées n'exploite pleinement ces ressources. Nous proposons et étudions alors deux algorithmes récursifs qui utilisent les mêmes principes que CALU mais qui sont plus appropriés pour des architectures à plu- sieurs niveaux de parallélisme. Pour analyser d'une façon précise et réaliste

Abstract:

Thesis: Ph. D., Massachusetts Institute of Technology, Department of Biological Engineering, 2018.<br>Cataloged from PDF version of thesis.<br>Includes bibliographical references.<br>Mucosal barrier tissues are prominent targets for drugs against infection and chronic inflammatory disorders. One such mucosal barrier tissue, the endometrium, undergoes monthly cyclic remodeling via hormone-mediated growth, immune cell recruitment and proteolytic breakdown. Hormone response disruption has been associated with numerous endometrial pathologies, including endometriosis, adenomyosis, and infertility, which impacts upwards of 10% of women during their reproductive years. Currently, our understanding of endometrial biology is limited by the ability to replicate complex 3D physiology in vitro. Our ability to parse disease mechanisms and test efficacy of therapeutic interventions relies on development of reproducible models, adaptable to the limited numbers of cells available from patient biopsies. In this thesis, I address a critical gap in accessible tools to study and control endometrial biology in vitro and do so in a manner that can be translated to other epithelial-stromal mucosal tissues. Using the endometrium as an example mucosal barrier, I first establish design principles for the development of a synthetic, modular extracellular matrix (ECM) hydrogel suitable for 3D functional co-culture of epithelial and stromal cells. This 'one-size- fits-all' matrix features components that can be remodeled by cells and that responds dynamically to sequester local cell-secreted ECM characteristic of each cell type enabling long-term, hormonally responsive co-cultures. Next, I establish methods to expand and cryopreserve primary human endometrial epithelial cells, which maintain barrier and secretory function, further enabling studies using primary cells. Finally, we use data-driven network modeling of secreted proteins to understand how variation in cytokine signaling may alter hormone responsiveness and proteolytic remodeling in primary epithelial-stromal co-cultures. With the ability to create and parse more complex 3D tissue models using primary cells to recapitulate healthy and diseased states, we further enable basic understandings of disease pathologies and subsequent drug discovery efforts aimed at inflammation, wound healing and immune modulation.<br>by Christi Dionne Cook.<br>Ph.

Abstract:

Multiple-antenna systems are capable of providing substantial improvement to wireless communication networks, in terms of data rate and reliability. Without utilizing extra spectrum or power resources, multiple-antenna technology has already been supported in several wireless communication standards, such as LTE, WiFi and WiMax. The surging popularity and enormous prospect of multiple-antenna technology require a better understanding to its fundamental performance over practical environments. Motivated by this, this thesis provides analytical characterizations of several seminal performance measures in advanced multiple-antenna systems. The analytical derivations are mainly based on finite dimension random matrix theory and a collection of novel random matrix theory results are derived. The closed-form probability density function of the output of multiple-input multiple-output (MIMO) block-fading channels is studied. In contrast to the existing results, the proposed expressions are very general, applying for arbitrary number of antennas, arbitrary signal-to-noise ratio and multiple classical fading models. Results are presented assuming two input structures in the system: the independent identical distributed (i.i.d.) Gaussian input and a product form input. When the channel is fed by the i.i.d. Gaussian input, analysis is focused on the channel matrices whose Gramian is unitarily invariant. When the channel is fed by a product form input, analysis is conducted with respect to two capacity-achieving input structures that are dependent upon the relationship between the coherence length and the number of antennas. The mutual information of the systems can be computed numerically from the pdf expression of the output. The computation is relatively easy to handle, avoiding the need of the straight Monte-Carlo computation which is not feasible in large-dimensional networks. The analytical characterization of the output pdf of a single-user MIMO block-fading channels with imperfect channel state information at the receiver is provided. The analysis is carried out under the assumption of a product structure for the input. The model can be thought of as a perturbation of the case where the statistics of the channel are perfectly known. Specifically, the average singular values of the channel are given, while the channel singular vectors are assumed to be isotropically distributed on the unitary groups of dimensions given by the number of transmit and receive antennas. The channel estimate is affected by a Gaussian distributed error, which is modeled as a matrix with i.i.d. Gaussian entries of known covariance. The ergodic capacity of an amplify-and-forward (AF) MIMO relay network over asymmetric channels is investigated. In particular, the source-relay and relay-destination channels undergo Rayleigh and Rician fading, respectively. Considering arbitrary-rank means for the relay-destination channel, the marginal distribution of an unordered eigenvalue of the cascaded AF channel is presented, thus the analytical expression of the ergodic capacity of the system is obtained. The results indicate the impact of the signal-to-noise ratio and of the Line-of-Sight component on such asymmetric relay network.

Abstract:

<p>This case study has shown how nearly every success and failure in the matrix structured Segment X was a result of leadership behaviour. If Project I was to be an unreserved success every leader on every level had to succeed in their efforts. After having interviewed employees and leaders, and observed several meetings the overall impression was of a well-functioning, mature matrix organization. However, it is not correct to say that Project I was an unreserved success. There were some areas within the matrix structure that appeared to be more troublesome than others. After having examined each of the seven related research questions the main research question should be answered: What constitutes an effective Norwegian matrix organization in terms of communication and leadership as perceived by its members/employees? In order for a leader in the matrix organization to succeed on a general level, it was perceived that he or she should be emotionally intelligent and possess social and communication skills. Communication skills that in particular were suggested to be of great importance were the ability to create a sense of commitment to organizational goals in each employee, and to be able to persuade the employees to reach set goals in time. Employees increasingly no longer ask “What should I do?” but “Why should I do it?”, and persuasion seemed in fact to be one of the more difficult aspects for the leaders of Segment X. Extensive interpersonal and communication skills were also perceived to be of great importance to meet the challenges of the matrix structure. The main challenge associated with the matrix structure was the distribution of resources. In order to handle this challenge in an effective way and avoid conflicts, respect for the current rules was pointed to as crucial by both functional and project leaders.</p><p>In general the most obvious challenge for Segment X and in particular Project I was the teams and the management of teams. The two teams of special interest in this case study experienced some serious problems. Team management and the composition of the teams were the main reasons that the teams struggled. Both these issues will be the responsibility of the functional management. Thus in a matrix structured organization where the use of work teams is necessary it is of great importance to in a more thorough way evaluate both the skills and style of the potential team leader and also consider the composition of the team. Since teams actually carry out the projects of the matrix organization, the effectiveness of the matrix organization is more or less dependent on well functioning teams.</p><p>The truly effective matrix organization is constituted first of all of socially skilled leaders on all levels who are effective persuaders, who are willing to respect the formal rules of the matrix structured organization, and who are able to alter their leadership style depending on the context. All this highlights the importance of and need for a stronger focus on leader communication and behaviour.</p><p>The results from this case study conducted in a Norwegian organization do not differ to any great extent from the findings of other relevant studies conducted in other countries (the literature reviewed in this thesis is mainly from English speaking countries). However, it does seem like the Norwegian organization (Segment X), and in particular in relation to Project I (as Project I formed the basis for this study) is a well functioning matrix organization, that has stared clear of some of the most obvious challenges mentioned by other research into matrix organizations. For instance the multiple reporting relationships that exist within a matrix organization were not mentioned to any great extent, neither by the leaders nor by the employees of Segment X.</p><p>In relation to further or future research within the area of organizational structure, leadership and leadership communication, several suggestions can be made. For this organization in particular it would be of value to conduct more research into the use of teams. As the teams are so important in a matrix structured organization like Segment X, more knowledge should be gained about the factors that will impact on the effectiveness of the team. One other question that could be raised is whether the necessary leadership skills and leadership communication will differ within a production oriented company compared to an innovation oriented company.</p><p>It is also of interest to be able to discuss why or if there are differences between a Norwegian matrix organization in terms of leadership and leadership communication, and matrix organizations in other countries. Future research will also benefit from using both qualitative and quantitative approaches, maybe especially in relation to investigate how communication skills of leaders are related to the feeling of commitment in the employees.</p>

Abstract:

There is a broad consensus that agri-food systems need to be transformed to address the mounting global challenges including food and nutrition security, environmental degradation, and socioeconomic inequities. However, agreement is lacking on what is needed to drive this transformation. This report builds on a sustainability analysis of different proposed pathways and approaches to address transformative needs. It also serves as a study of the drivers and agents that support the implementation of these proposed pathways in different cases around the globe. We recommend the adoption of a multi-level governance framework to coordinate the transformation of agri-food systems, guaranteeing the attainment of transformation goals across all levels. This includes global agreements and international goals at the international level, national transformation pathways at the country level, and the operational level embedded in local governance. This report introduces the Agri-food Systems Transformation Protocol as a decision-support protocol at the desired operational level serving different actors within agri-food systems. The Agri-food Systems Transformation Protocol proposes a four-stage and nine-step iterative process that can guide the development of transformation pathways in different contexts and at different levels of implementation. It was conceived during a workshop of the Expert Advisory Group of the Assessment and Communication of Climate Impacts of Food (CLIF) project in June 2023. The aim was to develop a step-by-step guide to transforming food systems that is not prescriptive and follows a rights-based, place-based, systems approach. The protocol was informed by background research on different case studies from the agri-food sector and advances the three principles of preserving the rights of people, ecosystem integrity, and integrity of the process. The background study identified the main drivers and agents of transformation by analysing 14 case studies from five continents, a selection that was finalized at the expert workshop. A transformation matrix that maps the agents and drivers with different steps of transformation process is also presented to aid the implementation of the protocol. This protocol is intended to be the first step in developing a transformative theory of change for agri-food systems, with the methodologies for each step being the subject of further development.

Abstract:

The article deals with the mental-existential relationship between ethnoculture, national identity and media culture as a necessary factor for their preservation, transformation, on the example of national original algorithms, matrix models, taking into account global tendencies and Ukrainian archetypal-specific features in Ukraine. the media actively serve the domestic oligarchs in their information-virtual and real wars among themselves and the same expansive alien humanitarian acts by curtailing ethno-cultural programs-projects on national radio, on television, in the press, or offering the recipient instead of a pop pointer, without even communicating to the audience the information stipulated in the media laws − information support-protection-development of ethno-culture national product in the domestic and foreign/diaspora mass media, the support of ethnoculture by NGOs and the state institutions themselves. In the context of the study of the cultural national socio-humanitarian space, the article diagnoses and predicts the model of creating and preserving in it the dynamic equilibrium of the ethno-cultural space, in which the nation must remember the struggle for access to information and its primary sources both as an individual and the state as a whole, culture the transfer of information, which in the process of globalization is becoming a paramount commodity, an egregore, and in the post-traumatic, interrupted-compensatory cultural-information space close rehabilitation mechanisms for national identity to become a real factor in strengthening the state − and vice versa in the context of adequate laws («Law about press and other mass media», Law «About printed media (press) in Ukraine», Law «About Information», «Law about Languages», etc.) and their actual effect in creating motivational mechanisms for preserving/protecting the Ukrainian language, as one of the main identifiers of national identity, information support for its expansion as labels cultural and geostrategic areas.

Abstract:

Use of the digital technologies is new and very productive approach for balance of different data. It is very important for balance of supply and demand and for increase of competitiveness of products. Various types of digital models were developed as a result of scientific research, they found reflection in article. Digital models for the description of the list of the sequences of steps and operations of various stages and process in general allow to install system of interrelations between operations and steps and to reach necessary log-ic, increase of effectiveness of any process. Object-relational models for establishment of communications between data of various blocks of databases and functional models of the choice of strategy of data balance form analytical base for justification of the choice of the direction of transformation of data. Models of a combination of a plurality of various data of the offer of products in the form of matrixes of multi-purpose optimization have double effect, because they allow not only to develop various options of data combina-tion, taking into account opportunities of change of location of products over the markets and temporary phases, but also to estimate aggregate useful effect from products. These models together with models of comparison of various options and the choice of optimal solutions allow to generate compatible strategic and current programs of the offer of products as a plurality of the output data balanced with each other and with data of demand. It is providing the best synergetic result. The developed methodology of creation of system of the interconnected digital models for transformation of data and generation of the output data of the situational-strategic program of the offer of products is a cornerstone of formation of new digital econ-omy – of economy of balanced data.
