791A programmer's guide to file processing
Introduces the many and powerful data structures for representing information physically (in contrast to a database management system that represents information with logical structures). Covers specialized data structures, and explains how to choose the appropriate algorithm or data structure for the job at hand. The four sections treat primary file organizations, bit level and related structures, tree structures, and file sorting...
792A quantum legacy : seminal papers of julian schwinger
This book volume includes many of Schwinger's most important papers, on the above and other topics, such as the theory of angular momentum and the theory of many-body systems. The papers collected here continue to underlie much of the work done by theoretical physicists today.

Chapter 1. Conventional analysis of the tunnel effect; Chapter 2. Theory of quantum measurement and observations; Chapter 3. Tunnelling from the viewpoint of quantum measurement.
794A quest for perspectives selected works of S. Chandrasekhar : with commentary
This invaluable book presents selected papers of S. Chandrasekhar, co-winner of the Nobel prize for physics in 1983 and a scientific giant well known for his prolific and monumental contribution to astrophysics, physic and applied mathematics. The reader will find here most of Chandrasekha's articles that led to major developments in various areas of physics and astrophysics.
795A quest for perspectives selected works of S. Chandrasekhar : with commentary
The reader will find here most of Chandrasekhar's articles that led to major developments in various areas of physics and astrophysics. There are also articles of a popular and historical nature, as well as some hitherto unpublished material based on Chandrasekhar's talks at conferences. Each section of the book contains annotations by the editor.
796A quest for symmetry : selected works of Bunji Sakita (World scientific series in 20th century physics)
This volume contains selected research papers of Professor Bunji Sakita. Included are his pioneering papers on SU(6) symmetry, strong coupling theory, string theory, supersymmetry and the method of collective co-ordinates. There is also a personal account of his journey in physics. The book seeks to bring to light some of the key concepts of modern high energy physics.
797A random walk down Wall Street : the time tested strategy for successful investing
An informative guide to financial investment discusses the current high tech boom, explains how to maximize gains and minimize losses, and examines a broad spectrum of financial opportunities, from mutual funds to real estate to gold.
798A rare homozygous variant of the NKX6-2 gene in association with profound intellectual disability
This is a study of five children with profound intellectual disability, spastic quadriplegia, and nystagmus in two distinct families. Whole exome sequencing (WES) identified a homozygous c.234dup variant in the NKX6-2 gene relating to Spastic ataxia 8 with hypomyelinating leukodystrophy - the underlying cause of severe neurodevelopmental impairment in both families. The study contributed additional data on NKX6-2 variants in Vietnamese patients with intellectual disabilities and explored the genotype-phenotype correlation. Furthermore, it emphasized the importance of early genetic testing in children presenting with developmental delay, spastic quadriplegia, and unexplained nystagmus, especially when brain MRI findings suggested hypomyelinating leukodystrophy. This approach will provide a critical basis for diagnosis, patient management, and genetic counseling.
799A raw deal : trade and the world's poor
A raw deal is about why the poor stay poor. It shows how they are exploited by the internationsl trading system and why changes are needed that will bring long- term benefits to the third world. This challenging book draws on the experience of Christian Aid's work overseas to show the prospects of the poor are blighted by decisions taken thousands of miles away.
800A Report of narrow gap welding
This paper presents experimental results of narrow gap butt welding of steel plates with greater thickness by using the Metal Active Gas (MAG) welding method. The mechanical properties of the welding joints were examined by metallographic method using the microhardness investigated in some specific submicro structure subzones, such as the weld center zone, heat-affected zone (HAZ), base metal region, and the boundary between the weld metal and the HAZ. The experiment results higlighted the graphical relation between the microhardness and the measuring distance in different subzones. The finding helps to forcast the quality and the loadability of the welding construction.
