In recent years computer systems have become increasingly complex and consequently the challenge of protecting these systems has become increasingly difficult. Various techniques have been implemented to counteract the misuse of computer systems in the form of firewalls, antivirus software and intrusion detection systems. The complexity of networks and dynamic nature of computer systems leaves ...

P rotecting groups have a long history in synthetic chemistry 1. A protecting group is covalently attached to one functional group to block its reactivity while a second functional group undergoes a chemical transformation, after which the protecting group is then removed (Fig. 1a). The use of protecting groups requires both protection and deprotection steps, so efficiency considerations dictat...

This paper seeks to uncover dominant configurations of inter-organizational relationships across the USA and Japan in the automotive industry. We integrate relevant theoretical concepts from transaction cost economics, organization theory and political economy to develop a conceptual model of inter-organizational relationships based on the fit between information processing needs and informatio...

We present a novel synthesis algorithm for procedurally generating complex curves. Our approach takes a simple example input curve specified by a user and automatically generates complex curves that resemble the input. The algorithm preserves many of the input shape features such as tangent directions, curvature, branch nodes, and closed loops. The overall approach is simple and can be used to ...

Dendritic configuration (or tree-shaped configurations) is ubiquitous in nature and li...

Protecting osmolytes are widespread small organic molecules able to stabilize the folded state of most proteins against various denaturing stresses in vivo. The osmophobic model explains thermodynamically their action through a preferential exclusion of the osmolyte molecules from the protein surface, thus favoring the formation of intrapeptide hydrogen bonds. Few works addressed the influence ...

The reciprocal relationship between humans and nature is determined based on their respective natures. This mutualism symbiosis a of use for mutual prosperity. Living together with means living in cooperation, help tolerance. whole becomes an inseparable entity; all things are interrelated functional have the same goal protecting preserving nature. Protecting environment key to survival fragile...
