A new parallel solver for the volumetric integral equations (IE) of electrodynamics is presented. The solver is based on the Galerkin method, which ensures convergent numerical solution. The main features include: (i) memory usage eight times lower compared with analogous IE-based algorithms, without additional restrictions on the background media; (ii) accurate and stable method to compute matrix coefficients corresponding to the IE; and (iii) high degree of parallelism. The solver’s computational efficiency is demonstrated on a problem of magnetotelluric sounding of media with large conductivity contrast, revealing good agreement with results obtained using the second-order finite-element method. Due to the effective approach to parallelization and distributed data storage, the program exhibits perfect scalability on different hardware platforms. © 2017 International Association for Mathematical Geosciences

The behavior of orbits for iterated polynomials has been widely studied since the dawn of discrete dynamics as a research field, in particular in the context of the complex quadratic family (Formula presented.), parametrized as (Formula presented.), with (Formula presented.). While more recent research has been studying the orbit behavior when the map changes along with the iterations, many aspects of non-autonomous discrete dynamics remain largely unexplored. Our work is focused on studying the behavior of pairs of quadratic maps (1) when iterated according to a rule prescribed by a binary template and (2) when the maps are organized as nodes in a network, and interact in a time-dependent fashion. We investigate how the traditional theory changes in these cases, illustrating in particular how the hardwired structure (the symbolic template, and respectively the adjacency graph) can affect dynamics (behavior of orbits, topology of Julia and Mandelbrot sets). Our current manuscript addresses the first topic, while the second topic is the subject of a subsequent paper. This is of potential interest to a variety of applications (including genetic and neural coding), since (1) it investigates how an occasional or a reoccurring error in a replication or learning algorithm may affect the outcome and (2) it relates to algorithms of synaptic restructuring and neural dynamics in brain networks. © 2016 Springer Science+Business Media Dordrecht

Author, educator and children's education advocate Rosella Calauti believes social literacy is a key skill in the context of the 21st century. Aiming to equip the younger generation with this modern world survival skill, she puts together "Friends" (published by AuthorHouse), an exquisitely woven tale of friendship that inspires young readers to nurture their social selves and build healthy, well-rounded relationships in the real world. "Friends" is specifically designed for tots 2 to 5 years old. During these formative years, the child experiences rapid growth and development and “Friends” supports the development of skills necessary for the establishment of a strong social ground as they strive to become independent. The book encourages young children to feel secure as they develop, and experience their first encounters of making friends, while they explore the world and continue to become individuals. It is ideal for teachers, parents and caregivers who wish to discuss how to share and play cooperatively. In addition to the topic of building friendships, the book also helps develop recognition of words that are opposites and introduces adverbs (here, there, and everywhere) as part of its educational aspect. It seeks to motivate children to inquire about friendships, relate to them, and suggests places to find friends, while strengthening reading and writing skills. An inspiring and educational book, "Friends" opens a whole world of new possibilities for children everywhere. This book has been awarded with the Purple Dragonfly Book Award, an award recognizing excellence in children’s literature given by Five Star Publications. About the Author Rosella Calauti, author and career changer, found her niche as a teacher. She completed a Master’s Degree in Art Education at Manhattanville College (Purchase, NY) and a second Master’s in Humanistic and Multi-Cultural Education at SUNY New Paltz (New Paltz, NY). She has two NY Teacher Certifications. Calauti is now dedicated to helping children, especially those in the Hudson Valley where she has worked for over 10 years.

Radiocarbon-dated sediment cores from the Champlain Valley (northeastern USA) contain stratigraphic and micropaleontologic evidence for multiple, high-magnitude, freshwater discharges from North American proglacial lakes to the North Atlantic. Of particular interest are two large, closely spaced outflows that entered the North Atlantic Ocean via the St. Lawrence estuary about 13,200-12,900cal yr BP, near the beginning of the Younger Dryas cold event. We estimate from varve chronology, sedimentation rates and proglacial lake volumes that the duration of the first outflow was less than 1yr and its discharge was approximately 0.1Sv (1 Sverdrup=106m3 s-1). The second outflow lasted about a century with a sustained discharge sufficient to keep the Champlain Sea relatively fresh for its duration. According to climate models, both outflows may have had sufficient discharge, duration and timing to affect meridional ocean circulation and climate. In this report we compare the proglacial lake discharge record in the Champlain and St. Lawrence valleys to paleoclimate records from Greenland Ice cores and Cariaco Basin and discuss the two-step nature of the inception of the Younger Dryas. © 2010 University of Washington.

Shared-mobility services facilitate distinctive forms of personal mobility, and their pay-as-you-go business model has been shown to offer substantial benefits relative to use of privately-owned cars. Such systems in general operate one of two business models, in one case where customers make advance reservations and the other in which use is spontaneous and cannot be reserved with any certainty. This paper proposes a market-clearing mechanism that draws on the strengths and mitigates the weaknesses of each of these two prevailing operating models, by allowing reservations (the right to use the service at a particular time and place in the future) to be traded in a futures market. We show that there is a revenue-positive role for the market-maker of the secondary-exchange market as well as for investors in shared-mobility futures. Introducing a secondary exchange market is Pareto efficient in that shared-mobility services are allocated to customers on the basis of maximum willingness-to-pay rather than first-come-first-served. Finally, from the point of view of each individual customer there would be a step-change in the reliability of accessing shared-mobility vehicles when and where needed, which can be expected to increase overall demand for the service.

This article examines the enduring ways that racial politics are masked by discourses of place and family in the history of juvenile justice in the USA. The tropes of place and family have been invoked since the inception of the USA’s juvenile justice system and have influenced the processes of policing, removal, and return, even as the latest incarnation of reforms focus on building juvenile justice facilities and alternatives to incarceration within urban areas. By pointing to recent manifestations of this rhetoric in New York, the article identifies the thread that links these claims together: the desire by social control agents for submission by the primarily impoverished and young people of color who defy legal authority. © 2015, © The Author(s) 2015.

Systems that enable high levels of vehicle-automation are now beginning to enter the commercial marketplace. Road vehicles capable of operating independently of real-time human control under an increasing set of circumstances will likely become more widely available in the near future. Such vehicles are expected to bring a variety of benefits. Two such anticipated advantages (relative to human-driver vehicle control) are said to be increased road network capacity and the freeing up of the driver-occupant's time to engage in their choice of leisurely or economically-productive (non-driving) tasks.In this study we investigate the implications for intersection capacity and level-of-service of providing occupants of automated (without real-time human control), autonomously-operating (without vehicle-to-X communication) cars with ride quality that is equivalent (in terms of maximum rates of longitudinal and lateral acceleration) to two types of rail systems: [urban] light rail transit and [inter-urban] high-speed rail. The literature suggests that car passengers start experiencing discomfort at lower rates of acceleration than car drivers; it is therefore plausible that occupants of an autonomously-operating vehicle may wish to instruct their vehicle to maneuver in a way that provides them greater ride comfort than if the vehicle-control algorithm simply mimicked human-driving-operation.On the basis of traffic microsimulation analysis, we found that restricting the dynamics of autonomous cars to the acceleration/deceleration characteristics of both rail systems leads to reductions in a signalized intersection's vehicle-processing capacity and increases in delay. The impacts were found to be larger when constraining the autonomous cars' dynamics to the more-restrictive acceleration/deceleration profile of high-speed rail. The scenarios we analyzed must be viewed as boundary conditions, because autonomous cars' dynamics were by definition never allowed to exceed the acceleration/deceleration constraints of the rail systems. Appropriate evidence regarding motorists' preferences does not exist at present; establishing these preferences is an important item for the future research agenda.This paper concludes with a brief discussion of research needs to advance this line of inquiry. © 2015 Elsevier Ltd.

Dualism and reductionism regarding the environment and statist and individualist notions of society may pervade the International Year of the Soil, but the related celebrations are useful in trying to awaken more people to the importance of what is appreciated already by millions of small-holding farmers, mainly women, and Aboriginal and Indigenous Peoples worldwide. The 21st Conference of the Parties (COPs) will decidedly silent much of any talk of soils or their close relationship to global warming with a cacophony of contrasting yet nearly all planet-compartmentalizing voices from the more influential sectors of world politics representing a small, largely hetero-masculinist and white moneyed human minority. The more influential media have anyway shown the usual disinterest in soils. Virtually no headlines or well-publicized investigative reports have appeared featuring the status of soils around the planet More prominent environmental organizations like Greenpeace and the Union of Concerned Scientists rarely concentrate their efforts on soil protection issues Were the World Food and Agriculture Organization (FAO) actually to succeed in realizing the aforementioned aims, much real estate speculation, mining, and other soil-destructive activities would have to cease and capitalist farming would have to be transformed, with prospects of major financial losses to, for example, colossal firms monopolizing the main means of industrial farming production and those involved in agriculturally related financial derivatives. Major state investments would also have to be redirected and infrastructure would have to be provided so as to enable, finally, the proper study and monitoring of soils in most of the world.

We present a new parallel (MPI+OpenMP) solver for the 3D volumetric integral equations (IE) of electrodynamics. The solver requires only half of an amount of memory compared with the other IE solvers and has high degree of parallelization. The computational experiments, including the ones performed for the high conductivity contrast problems, show solver's efficiency. The developed software is distributed under the GPLv2 license.
