Impact of biomineralization on resin/biomineralized dentin bond longevity in a minimally invasive approach: An "in vitro" 18-month follow-up.

Dental Materials, 2021
OBJECTIVES To determine the impact of treating caries-affected dentin (CAD) with: 0.2% sodium fluoride (NaF), casein phosphopeptide-amorphous calcium phosphate (CPP-ACP/MI Paste™) or peptide P11-4 (Curodont™ Repair) on the longevity of resin/CAD ...

Local risk‐minimization with longevity bonds

Applied Stochastic Models in Business and Industry, 2014
AbstractThis paper studies the criterion of local risk‐minimization for life insurance contracts in a financial market, which includes longevity bonds. The longevity bond is a bond specifying payments, which are linked to the current number of survivors in a given portfolio of insured lives.

HEDGING MORTALITY CLAIMS WITH LONGEVITY BONDS

ASTIN Bulletin, 2013
AbstractWe study mean–variance hedging of a pure endowment, a term insurance and general annuities by trading in a longevity bond with continuous rate payments proportional to the survival probability. In particular, we discuss the introduction of a gratification annuity as an interesting insurance product for the life insurance market.

Longevity risk management for government pension fund: Longevity bonds design

2013 6th International Conference on Information Management, Innovation Management and Industrial Engineering, 2013
The longevity risk of individuals has been underestimated for many years. With the deepening of aging degree, the management of longevity risks has become a serious problem to government pension fund. This paper investigates the hedging strategies for longevity risk management using securitized products.

Composite Resin Compatibility and Bond Longevity of a Dentin Bonding Agent

Journal of Dental Research, 1985
The shear strength of a commercial dentin bonding agent was studied using human dentin in vitro. The agent was tested for compatibility with three proprietary composite resins. In addition, some samples were subjected to prolonged water immersion and thermocycling to determine effects on bond strength. There was no statistically significant difference

Clinical longevity of resin‐bonded bridges bonded using a vinyl‐thiol primer

Journal of Oral Rehabilitation, 2003
summary  The purpose of this study is to clinically confirm the adhesive effect of a vinyl‐thiol primer (V‐Primer) for precious alloys. Further, we examined the failure of resin‐bonded bridges (RBBs) in order to improve the clinical longevity of RBBs, and to analyse the causes of failure. Twenty‐six RBBs were bonded with V‐primer and Super Bond C &

Multifunctional additive with dynamic sacrificial S-S bond for building self-assembled monolayers of Zn-ion battery with improved stability and longevity

Energy & Environmental Science
Aqueous zinc-ion batteries (AZIBs) possess a tremendous prospect for large-scale energy storage. Nevertheless, the interfacial stability and cyclic reversibility for Zn anode are impeded by the unregulated growth of Zn...

Pricing Longevity Bonds Under the Uncertainty Theory Framework

International Journal of Pattern Recognition and Artificial Intelligence, 2019
This paper aims to develop a new pricing approach for longevity bonds under the uncertainty theory framework. First, we describe the life expectancy by a canonical uncertain process and illustrate the dynamic of short interest rate via an uncertain Vasicek interest rate model.
