Development of State-and-Transition Models (STM): Integrating Ecosystem Function, Structure and Energy to STM
The main objective of an ecosystem sustainable management is to preserve itscapacity to respond and adapt to current disturbances and/or future changes, and maintain theprovision of environmental goods and services. Two very important properties linked to thisobjective are the ecosystem resilience and resistance to disturbance factors. The objective ofthis paper is to recommend conceptual modif...
متن کاملReducing False Aborts in STM Systems
Transactional memory (TM) continues to be themost promising approach replacing locks in concurrent programming, but TM systems based on software (STM) still lack the desired performance when compared to fine-grained lock implementations. It is known that the critical operation in TM systems is to ensure the atomicity and isolation of concurrently executing threads. This task is known as the rea...
متن کاملSplicing systems using merge and separate operations
We study in details how to control molecules in a set of splicing tubes, in such a way that we can genereate any recursively enumerable language by allowing them to split and join (splice), but also by separating the molecules of a tube, according to the presence of a pattern in them, and by merging tubes when needed. We show that this new model of distributed splicing system is computationally...
متن کاملSupporting STM in Distributed Systems: Mechanisms and a Java Framework
We present HyFlow — a distributed software transactional memory (D-STM) framework for distributed concurrency control. Lockbased concurrency control suffers from drawbacks including deadlocks, livelocks, and scalability and composability challenges. These problems are exacerbated in distributed systems due to their distributed versions which are more complex to cope with (e.g., distributed dead...
متن کاملMolecular Dynamics in Two-Dimensional Supramolecular Systems Observed by STM
Since the invention of scanning tunneling microscopy (STM), 2D supramolecular architectures have been observed under various experimental conditions. The construction of these architectures arises from the balance between interactions at the medium-solid interface. This review summarizes molecular motion observed in 2D-supramolecular structures on surfaces using nanospace resolution STM. The ob...
