Links not concordant to the Hopf link [PDF]
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]
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 ...

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 ...

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