Links not concordant to the Hopf link [PDF]

open access: yesMathematical Proceedings of the Cambridge Philosophical Society, 2014
AbstractWe give new Casson–Gordon style obstructions for a two–component link to be topologically concordant to the Hopf link.

Link services or link agents? [PDF]

open access: yesProceedings of the ninth ACM conference on Hypertext and hypermedia : links, objects, time and space---structure in hypermedia systems links, objects, time and space---structure in hypermedia systems - HYPERTEXT '98, 1998
A general link service for the WWW has been used within an Electronic Libraries' project. Experience using it shows that as the links become increasingly interesting to the user, processing them becomes increasingly expensive. Eventually textual analysis, ontological services and remote database lookups conflict with the goal of prompt delivery of ...

The link in Linking

open access: yesIndian Pacing and Electrophysiology Journal, 2013
We present 2 cases of the slow-fast form of AVNRT with initially narrow QRS complexes followed by sudden unexpected transition to persistently wide QRS complexes due to aberrant intraventricular conduction. Introduction of a properly timed extrastimulus in one case and critical oscillations in cycle length due to short-long coupling in the second case ...

Experimental Testbed and Methodology for the Assessment of RTK GNSS Receivers Used in Precision Agriculture

open access: yesIEEE Access, 2020
Precision Agriculture (PA) refers to applications asking for reliable and highly available precise positions, at centimeter level, in most of operational scenarios. Machinery guidance, automatic steering and controlled traffic farming enable machinery to

Ground-State Analysis for an Exactly Solvable Coupled-Spin Hamiltonian [PDF]

open access: yes, 2013
We introduce a Hamiltonian for two interacting $su(2)$ spins. We use a mean-field analysis and exact Bethe ansatz results to investigate the ground-state properties of the system in the classical limit, defined as the limit of infinite spin (or highest ...

Inner Margins of the Literary Digital Text: From Allusion to Rewriting

open access: yesDigital Studies, 2015
This paper aims to take into account the process of annotation as it can be inserted in a literary text driven by digital culture. Focusing on a corpus of digital literary texts, it will study how writers use hyperlinking as a way to build a network of ...

Improving market access opportunities for urban small, medium and micro-enterprises in South Africa [PDF]

open access: yesUrbani Izziv, 2013
Since the democratic transition of 1994, the promotion of the small, medium and micro-enterprise (SMME) economy has been a core focus of South African government policy.

Some spectral equivalences between Schrodinger operators [PDF]

open access: yes, 2008
Spectral equivalences of the quasi-exactly solvable sectors of two classes of Schrodinger operators are established, using Gaudin-type Bethe ansatz equations. In some instances the results can be extended leading to full isospectrality. In this manner we

Exactly Solvable BCS-BEC crossover Hamiltonians [PDF]

open access: yes, 2013
We demonstrate a novel approach that allows the determination of very general classes of exactly solvable Hamiltonians via Bethe ansatz methods. This approach combines aspects of both the co-ordinate Bethe ansatz and algebraic Bethe ansatz.
