conclusions it was observed that the success and survival rate of maxillary molar immediate implant was relatively high and similar to those of conventional delayed implants. results immediate implants were most frequently used for incisor and premolar sites and there is very little data available on immediate implantation in the molar area. in this research, we reviewed all the existing papers...

We model the introduction of a new payment method that competes with an existing payment method. Due to network adoption effects, there are two symmetric pure strategy equilibria in which only one of the two payment methods is used. The equilibrium where only the new payment method is used is socially optimal. In an experiment, we find that, depending on the fixed fee for acceptance of the new ...

Respondent driven sampling (RDS) is a network sampling technique typically employed for hard-to-reach populations (e.g. drug users, men who have sex with men, people with HIV). Similar to snowball sampling, initial seed respondents recruit additional respondents from their network of friends. The recruiting process repeats iteratively, thereby forming long referral chains. Unlike in snowball sa...

Crime and the Labour Market: Evidence from a Survey of Inmates In this paper data from a survey of 1,771 inmates conducted in 31 German prisons provide microeconometric evidence on the relationship between individual anticipated labour market opportunities and the perceived probability of future recidivism. Results show that inmates with poor labour market prospects expect a significantly highe...

We study the development of conjunctive keyword searchable scheme which enables one to search encrypted documents by using more than one keyword. The notion of conjunctive keyword searching was presented by Golle et al. in 2004. However, their security model was constructed in a symmetric-key setting which is not applicable for the overall applications in the reality. So Park et al. extended Go...

In this paper we present several proofs on the extension of M. Riesz fractional integration and di¤erentiation to the contexts of spaces of homogeneous type and measure metric spaces with non-doubling measures. 1. Introduction, some de…nitions, and a basic lemma Professor M. Ash asked me to write a survey article on some of the results that Stephen Vági and I obtained in the nineties on fractio...

Patient-ventilator asynchrony/dysynchrony is a mismatch between the patient and ventilator's delivered breaths ability of ventilator to meet demands. Any factor that alters harmony these two components produces asynchrony, which can cause discomfort an increase in patient's work breathing. Delayed cycling occurs when neural time less than mechanical ventilator. Keywords: ventilator, delayed cyc...
