O(N^2) fragmentation algorithm [PDF]

open access: yes, 2019
Collisional fragmentation is a ubiquitous phenomenon arising in a variety of astrophysical systems, from asteroid belts to debris and protoplanetary disks. Numerical studies of fragmentation typically rely on discretizing the size distribution of colliding objects into a large number N of bins in mass space, usually logarithmically spaced.

Abstract Computation in Schizophrenia Detection through Artificial Neural Network Based Systems

open access: yesThe Scientific World Journal, 2015
Schizophrenia stands for a long-lasting state of mental uncertainty that may bring to an end the relation among behavior, thought, and emotion; that is, it may lead to unreliable perception, not suitable actions and feelings, and a sense of mental ...

Geant4 hadronic physics status and validation for large HEP detectors

open access: yes, 2003
Optimal exploitation of hadronic final states played a key role in successes of all recent collider experiment in HEP, and the ability to use hadronic final states will continue to be one of the decisive issues during the analysis phase of the LHC ...

Performance analysis of data fragmentation techniques on a cloud server

open access: yesInternational Journal of Grid and Utility Computing, 2019
The advancements in virtualisation and distributed computing have allowed the cloud paradigm to become very popular among users and resources. It allows companies to save costs on infrastructure and maintenance and to focus on the development of products.

Augmenting Tractable Fragments of Abstract Argumentation [PDF]

open access: yesarXiv, 2011
We present a new and compelling approach to the efficient solution of important computational problems that arise in the context of abstract argumentation. Our approach makes known algorithms defined for restricted fragments generally applicable, at a computational cost that scales with the distance from the fragment.

Tracking granules on the Sun's surface and reconstructing horizontal velocity fields: I. the CST algorithm

open access: yes, 2007
Determination of horizontal velocity fields on the solar surface is crucial for understanding the dynamics of structures like mesogranulation or supergranulation or simply the distribution of magnetic fields.

Simulating Parton Fragmentation on Quantum Computers

open access: yes
Parton fragmentation functions (FFs) are indispensable for understanding processes of hadron production ubiquitously existing in high-energy collisions, but their first principle determination has never been realized due to the insurmountable difficulties in encoding their operator definition using traditional lattice methodology.

Binary formation and mass function variations in fragmenting discs with short cooling times

open access: yes, 2008
Accretion discs at sub-pc distances around supermassive black holes are likely to cool rapidly enough that self-gravity results in fragmentation. Here, we use high-resolution hydrodynamic simulations of a simplified disc model to study how the outcome of

Current models broadly neglect specific needs of biodiversity conservation in protected areas under climate change

open access: yesBMC Ecology, 2011
Background Protected areas are the most common and important instrument for the conservation of biological diversity and are called for under the United Nations' Convention on Biological Diversity. Growing human population densities, intensified land-use,
