Laura Olson is one of a small but energetic and influential group of Christian political scientists determined to bring the debate politically legitimate called it either racist or sexist. Yet, somewhat surprisingly, African American pastors held the most consistently conservative views on family values, although they also saw the connections among crime, violence, and the deterioration of the family. Within the authorÕs intentionally limited scope, this is an excellent study, but one should be cautious about generalizing.

Distributed joint congestion control and routing optimization has received a significant amount of attention recently. To date, however, most of the existing schemes follow a key idea called the back-pressure algorithm. Despite having many salient features, the first-order sub gradient nature of the back-pressure based schemes results in slow convergence and poor delay performance. To overcome these limitations, the present study was made as first attempt at developing a second-order joint congestion control and routing optimization framework that offers utility-optimality, queue-stability, fast convergence, and low delay.  Contributions in this project are three-fold. The present study propose a new second-order joint congestion control and routing framework based on a primal-dual interior-point approach and established utility-optimality and queue-stability of the proposed second-order method. The results of present study showed that how to implement the proposed second-order method in a distributed fashion.

Abstract The study of monasticism in Russia has found new acolytes since the dissolution of the Soviet Union. With the separation of the Soviet republics, religion became, and continues to become, a vibrant subfield of Russian studies. This article examines the problems inherent in attempting to grasp the day-to-day life of monks and monasteries given their individual characteristics, social classes, roles, and the wide variety, yet often limited scope, of various texts and material objects that can be used as sources. The vast source base is an embarrassment of riches in one sense, but problematic in another as prescriptive and normative texts must be understood in context. One important element that has not been directly addressed is the cacophony of sound, the interruptions, and the distractions of the constant activity of expanding cloisters in the sixteenth and seventeenth centuries. How did monks maintain their spiritual path and pious duties when on service expeditions outside the monastery: when engaged in salt-production, fishing, trade, rent-collecting, or other activities outside its walls? How intrusive were building projects, which abounded in the period, or even efforts to adorn the churches? How strict was oversight, or how weak? Such questions still need answers and can only be fully understood by integrating diverse source bases. This article uses Solovki, Holy Trinity, and Kirillov monasteries to exemplify the problems that remain in understanding the daily lives of monastics and their adherents within and without the confines of the cloister.

Multi Agent

Multi-Agent Systems (MAS) have been used to solve several optimization problems in control systems. MAS allow understanding the interactions between agents and the complexity of the system, thus generating functional models that are closer to reality. However, these approaches assume that information between agents is always available, which means the employment of a full-information model. Some tendencies have been growing in importance to tackle scenarios where information constraints are relevant issues. In this sense, game theory approaches appear as a useful technique that use a strategy concept to analyze the interactions of the agents and achieve the maximization of agent outcomes. In this paper, we propose a distributed control method of learning that allows analyzing the effect of the exploration concept in MAS. The dynamics obtained use Q-learning from reinforcement learning as a way to include the concept of exploration into the classic exploration-less Replicator Dynamics equation. Then, the Boltzmann distribution is used to introduce the Boltzmann-Based Distributed Replicator Dynamics as a tool for controlling agents behaviors. This distributed approach can be used in several engineering applications, where communications constraints between agents are considered. The behavior of the proposed method is analyzed using a smart grid application for validation purposes. Results show that despite the lack of full information of the system, by controlling some parameters of the method, it has similar behavior to the traditional centralized approaches.

AbstractHydrogen atom abstraction (HAT) from C(sp3)–H bonds of naturally abundant alkanes for alkyl radical generation represents a promising yet underexplored strategy in the alkylation reaction designs since involving stoichiometric oxidants, excessive alkane loading, and limited scope are common drawbacks. Here we report a photo-induced and chemical oxidant-free cross-dehydrogenative coupling (CDC) between alkanes and heteroarenes using catalytic chloride and cobalt catalyst. Couplings of strong C(sp3)–H bond-containing substrates and complex heteroarenes, have been achieved with satisfactory yields. This dual catalytic platform features the in situ engendered chlorine radical for alkyl radical generation and exploits the cobaloxime catalyst to enable the hydrogen evolution for catalytic turnover. The practical value of this protocol was demonstrated by the gram-scale synthesis of alkylated heteroarene with merely 3 equiv. alkane loading.
