Navier-Stokes Equations on R3 x [0, T] (Hardcover, 1st ed. 2016): Frank Stenger, Don Tucker, Gerd Baumann Navier-Stokes Equations on R3 x [0, T] (Hardcover, 1st ed. 2016)

In this monograph, leading researchers in the world of numerical analysis, partial differential equations, and hard computational problems study the properties of solutions of the Navier-Stokes partial differential equations on (x, y, z, t) 3 x [0, T]. Initially converting the PDE to a system of integral equations, the authors then describe spaces A of analytic functions that house solutions of this equation, and show that these spaces of analytic functions are dense in the spaces S of rapidly decreasing and infinitely differentiable functions. This method benefits from the following advantages: The functions of S are nearly always conceptual rather than explicit Initial and boundary conditions of solutions of PDE are usually drawn from the applied sciences, and as such, they are nearly always piece-wise analytic, and in this case, the solutions have the same properties When methods of approximation are applied to functions of A they converge at an exponential rate, whereas methods of approximation applied to the functions of S converge only at a polynomial rate Enables sharper bounds on the solution enabling easier existence proofs, and a more accurate and more efficient method of solution, including accurate error bounds Following the proofs of denseness, the authors prove the existence of a solution of the integral equations in the space of functions A 3 x [0, T], and provide an explicit novel algorithm based on Sinc approximation and Picard-like iteration for computing the solution. Additionally, the authors include appendices that provide a custom Mathematica program for computing solutions based on the explicit algorithmic approximation procedure, and which supply explicit illustrations of these computed solutions.

Scientific research shows how experience shapes the organization of the human brain through mechanisms of neural plasticity, which capture the information of the world within the connections among neurons. To understand this plasticity, it is important to look to the developmental mechanisms through which the brain grows from a single cell in embryogenesis to achieve the complex architecture of the human brain. The process of neural morphogenesis involves exuberant formation of neuronal connections, and then subtractive elimination of unused connections. This process is continued after birth, providing the neural plasticity of learning that allows cognitive development in infancy and childhood. Recognizing this continuity suggests an interesting insight; cognition is a reflection of neural development throughout the life span. With this insight, the authors of Cognition and Neural Development examine the embryonic development of the brain to appreciate the dimensions of developmental momentum that shape the neural and psychological development of our lives. Human brain embryogenesis involves gradients of trophic factors that guide the migration of neurons from ventricular proliferative zones to organize the architecture of the cerebral hemispheres. The architecture of human cognition involves a functional differentiation of dorsal (pyramidal) and ventral (granular) corticolimbic divisions. This differentiation is a defining feature of not just human but mammalian neuroanatomy, The separation of pyramidal and granular cortical architectures appeared with the evolution of the six-layered mammalian neocortex from the three-layered primitive general cortex of reptiles and amphibians. The functional differentiation of the dorsal and ventral divisions of the cerebral hemispheres has been shown to be integral to multiple levels of psychological function, from elementary motivation to the most complex forms of executive self-regulation. Through an evolutionary-developmental analysis of cortical differentiation, the authors approach the basic questions of psychological function in novel ways.

Vera is the fourth book in the action 'Evil Series" and it begins with Vera's life from the time she was 11 years old. It answers the question many reads may have in their minds. "Just what made Vera the person she is?" It follows her early childhood experiences, her education and FBI Academy training. Then she takes the lead in an investigation to stop white trafficking that spans the globe. There are the usual array of diabolic characters, some old and some new. Ed Kinsley, Carla Jones, Kevin Kinsley, and Allison Hart all play parts of their own that keeps the pace of the book on the move. You will meet Rosa Blanca, a character who will intrigue you. The investigation starts when Longshoremen working the Port of Oakland detect a sick odor emanating from a 40 cargo container, that originate from Bangkok Thailand. Inside the back half of the container, that was listed as containing furniture, the bodies of a dozen young oriental women were found. The their cause of death was not apparent. Who they are is unknown. What was their intended destination and end use are all masteries that must be solved by Vera Evans and her partner.

Writing this book has been a joyful experience for the author; remembering old fishing buddies, the good times shared, and retelling the funny stories that made each trip a special memory to be cherished for many years to come. Don Tucker has been blessed to grow up in a small town with many "characters" as citizens, and he hopes to give the reader a smile by sharing the humor of many good times. Whenever he is having a "bad" day or just feeling blue, he simply opens up his "Angler's Chest" full of smiles and memories and cheers up. Fishing has always been an important part of what makes life worth living. It's the perfect sport. There are so many kinds of fish, with even more ways to catch them. There's an angle for every angle. All you need is water and the ability to think big Fishing floats troubles away, renews the spirit, and fills your heart with joy. Fishing is not a contest against the fish, but a contest with nature and discovering its special wonders. It is for all ages, young and old. So, sit back and relax. Take your shoes off, and feel the river mud between your toes.
