Zk-Magic Labeling of Cycle of Graphs

Graph labeling is currently an emerging area in the research of graph theory. A graph labeling is an assignment of integers to vertices or edges or both subject to certain conditions. A detailed survey was done by Gallian in [6]. If the labels of edges are distinct positive integers and for each vertex v the sum of the labels of all edges incident with v is the same for every vertex v in the given graph then the labeling is called a magic labeling

Symmetry in Graph Theory

This book contains the successful invited submissions to a Special Issue of Symmetry on the subject of ""Graph Theory"". Although symmetry has always played an important role in Graph Theory, in recent years, this role has increased significantly in several branches of this field, including but not limited to Gromov hyperbolic graphs, the metric dimension of graphs, domination theory, and topological indices. This Special Issue includes contributions addressing new results on these topics, both from a theoretical and an applied point of view

Electrophysiological characterization of neuronal diversity in the substantia nigra pars reticulata in control and parkinsonian mice.

217 p.Los ganglios de la base son un conjunto de núcleos conectados entre sí que conforman un circuito neuronal encargado de controlar el movimiento voluntario. La substantia nigra pars reticulata (SNr) forma parte de este circuito y además posee un lugar privilegiado dentro de esta red siendo así la estructura que integra toda la información y permite la selección y la ejecución de tareas motoras. En la enfermedad de Parkinson (EP), esta función integradora y de selección de acciones se ve perjudicada, lo que conduce a la aparición de los síntomas motores de la EP. Estudios recientes han identificado varios tipos de neuronas dentro de la SNr, cuyas funciones en el control motor son actualmente desconocidas. El objetivo de mi doctorado consistió en caracterizar estos tipos de neuronas con el objetivo de desarrollar estrategias terapéuticas más selectivas para así restaurar la función motora en modelos de roedores con EP. Para ello combinamos técnicas inmunohistoquímicas y electrofisiológicas en una línea de ratones que nos permitía diferenciar entre dos tipos de neuronas y observar qué subpoblación era más susceptible a la EP y al consiguiente tratamiento con L-DOPA (tratamiento por excelencia en EP). El conocimiento generado por este proyecto de investigación básica permitirá el desarrollo de enfoques terapéuticos para reducir los síntomas motores en los pacientes con EP

Beyond wild walls there is algebraicity and exponential growth (of BPS indices)

textThe BPS spectrum of pure SU(3) four-dimensional super Yang-Mills with N=2 supersymmetry (a theory of class S(A)) exhibits a surprising phenomenon: there are regions of the Coulomb branch where the growth of BPS-indices with the charge is exponential. We show this using spectral networks and, independently, using wall-crossing formulae and quiver methods. The technique using spectral networks hints at a general property dubbed "algebraicity": generating series for BPS-indices in theories of class S(A) (a class of N=2 four-dimensional field theories) are secretly algebraic functions over the rational numbers. Kontsevich and Soibelman have an independent understanding of algebraicity using indirect techniques, however, spectral networks give a distinct reason for algebraicity with the advantage of providing explicit algebraic equations obeyed by generating series; along these lines, we provide a novel example of such an algebraic equation, and explore some relationships to Euler characteristics of Kronecker quiver stable moduli. We conclude by proving that exponential asymptotic growth is a corollary of algebraicity, leading to the slogan "there are either finitely many BPS indices or exponentially many" (in theories of class S(A)).Physic

Practicing Biomedicine at the Albert Schweitzer Hospital 1913-1965

Tizian Zumthurm uses the extraordinary hospital of an extraordinary man to produce novel insights into the ordinary practice of biomedicine in colonial Central Africa. His investigation of therapeutic routines in surgery, maternity care, psychiatry, and the treatment of dysentery and leprosy reveals the inco-herent nature of biomedicine – and not just in Africa. Reading rich archival sources against and along the grain, the author combines concepts that appeal to those interested in the history of medicine and colonialism. Through the micro-cosm of the hospital, Zumthurm brings to light the social worlds of Gabonese patients as well as European staff. By refusing to easily categorize colonial medi-cal encounters, the book challenges our understanding of biomedicine as solely domineering or interactive. Readership: People interested in the history of medicine, especially in the colonies. Practitioners of Global Health. Students of Medical History. Historians of Africa. People interested in the work of Albert Schweitzer

Proceedings of the XIII Global Optimization Workshop: GOW'16

[Excerpt] Preface: Past Global Optimization Workshop shave been held in Sopron (1985 and 1990), Szeged (WGO, 1995), Florence (GO’99, 1999), Hanmer Springs (Let’s GO, 2001), Santorini (Frontiers in GO, 2003), San José (Go’05, 2005), Mykonos (AGO’07, 2007), Skukuza (SAGO’08, 2008), Toulouse (TOGO’10, 2010), Natal (NAGO’12, 2012) and Málaga (MAGO’14, 2014) with the aim of stimulating discussion between senior and junior researchers on the topic of Global Optimization. In 2016, the XIII Global Optimization Workshop (GOW’16) takes place in Braga and is organized by three researchers from the University of Minho. Two of them belong to the Systems Engineering and Operational Research Group from the Algoritmi Research Centre and the other to the Statistics, Applied Probability and Operational Research Group from the Centre of Mathematics. The event received more than 50 submissions from 15 countries from Europe, South America and North America. We want to express our gratitude to the invited speaker Panos Pardalos for accepting the invitation and sharing his expertise, helping us to meet the workshop objectives. GOW’16 would not have been possible without the valuable contribution from the authors and the International Scientific Committee members. We thank you all. This proceedings book intends to present an overview of the topics that will be addressed in the workshop with the goal of contributing to interesting and fruitful discussions between the authors and participants. After the event, high quality papers can be submitted to a special issue of the Journal of Global Optimization dedicated to the workshop. [...
