Database outsourcing is becoming increasingly popular introducing a new paradigm, called database-as-a-service, where an encrypted client’s database is stored at an external service provider. Existing proposals for querying encrypted databases are based on the association, with each encrypted tuple, of additional indexing information obtained from the plaintext values of attributes that can be ...

Most extensible database systems support addition of new indexes or new data types. However, the reference patterns exhibited by these new indexes may not be efficiently supported by existing buffer replacement strategies. In this paper, we propose a new mechanism that allows an index method to pass replacement hints to the buffer manager by assigning priority values to the buffer pages to refl...

INTRODUCTION We aimed to evaluate the intralobar renal arteries indexes using the Doppler ultrasonography indexes, which have become the established method of kidney monitoring, in living unrelated kidney donors during the postnephrectomy period. MATERIALS AND METHODS In this prospective study, we evaluated and followed up 34 living unrelated kidney donors. The Doppler ultrasonography indexes...

BACKGROUND The definitive incorporation of heart rate variability (HRV) as a clinical tool depends on the development of more confident techniques of measurement. The length of the studies is a critical issue. Whereas Holter studies allow the monitorization at different hours and activities, short-term recordings allow the control of environmental conditions. Recording length is also strongly r...

Multiple-trait selection indexes should include all of the economically-relevant traits that influence the profitability of beef cattle production. They provide an economic evaluation of the genetic differences among sires, and an objective way to determine likely differences in the profitability of progeny from different sires. In contrast to the swine, poultry, sheep, and dairy cattle industr...

Paced breathing is a frequently performed technique for cardiovascular autonomic studies. The relative timing of inspiration and expiration during paced breathing, however, is not consistent. We, therefore, examined whether indexes of heart rate variability and spontaneous baroreflex sensitivity would be affected by the respiratory time ratio that is set. We studied 14 healthy young adults who ...

Introduction: We aimed to evaluate the intralobar renal arteries indexes using the Doppler ultrasonography indexes, which have become the established method of kidney monitoring, in living unrelated kidney donors during the postnephrectomy period. Materials and Methods: In this prospective study, we evaluated and followed up 34 living unrelated kidney donors. The Doppler ultrasonography indexes...

The concept of Genealogical Sorting Indexes (GSIs) was first introduced by Cummings et al. [1]. Given a set of observations belonging to different groups (represented in the form of a hierarchial tree), the Genealogical Sorting Index (GSI) value obtained for a particular group provides a quantitative measure of how closely the observations belonging to this group have clustered in the given tre...
