UNLABELLED PREMISE OF THE STUDY Phylogenetic and microsatellite markers were developed for Tulasnella mycorrhizal fungi to investigate fungal species identity and diversity. These markers will be useful in future studies investigating the phylogenetic relationship of the fungal symbionts, specificity of orchid-mycorrhizal associations, and the role of mycorrhizae in orchid speciation within ...

ABSTRACT A growing number of jurisdictions now request economic data in support of their decision-making procedures for the pricing and/or reimbursement of health technologies. Because more jurisdictions request economic data, the burden on study sponsors and researchers increases. There are many reasons why the cost-effectiveness of health technologies might vary from place to place. Therefore...

Information systems use research has investigated post-adoption issues as a means for identifying the factors that are relevant for long term IS success. Our objective in this study is to investigate voluntary adoption decisions of new software in an organizational setting. We study how attributes of prior use, perceived ease of use and perceived usefulness affect knowledge transferability and ...

This work explores the problem of using biometric data to achieve non-transferability of anonymous credentials; that is, sharing of anonymous credentials, which allow one to anonymously authenticate, can be severely limited if their use requires possession of the credential owner’s biometric. We target to provide strong security guarantees using minimal trust assumptions, namely that a fresh re...

The recently proposed Partition Theory (PT) (J. Phys. Chem. A 2007, 111, 2229), is illustrated on a simple one-dimensional model of a heteronuclear diatomic molecule. It is shown that a sharp definition for the charge of molecular fragments emerges from PT, and that the ensuing population analysis can be used to study how charge redistributes during dissociation and the implications of that red...

Electronic tickets demonstrate, without the use of paper, the possession of an authorization or access to a determined service. In this scenario, some security requirements must be accomplished. Moreover, some determined services should guarantee the anonymity of the users in the system. In addition to these requirements, the transferability of a ticket from one user to another (without involvi...

A pseudopotential generation method is presented which significantly improves transferability. The method exploits flexibility contained in the separable Kleinman-Bylander form of the nonlocal pseudopotential @Phys. Rev. Lett. 48, 1425 ~1982!#. By adjusting the functional form of the local potential, we are able to improve the agreement with all-electron calculations. Results are presented for ...

Purpose: This paper reports on a project aimed at moving Foster’s Nonlinear Model of Information Seeking Behaviour forwards from an empirically based model focussed on one setting and towards one that is robustly transferable and enables testing of the model in other information seeking situations. Methodology: The method utilised recoding of the original dataset, comparison of code decisions, ...

Starting from either the exchange or the exchange-correlation density together with Bader’s definition of an atom in a molecule, an atomic hole density function can be defined. Contour maps of atomic hole density functions are able to show how the electron density of each atom in a molecule is partially delocalized into the rest of atoms in the molecule. The degree of delocalization of the atom...

A potentially serious problem with current digital signature schemes is that their underlying hard problems from number theory may be solved by an innovative technique or a new generation of computing devices such as quantum computers. Therefore while these signature schemes represent an efficient solution to the short term integrity (unforgeability and non-repudiation) of digital data, they pr...
