The effect of zinc borate (ZB) on the cure kinetics of commercial phenol–formaldehyde oriented strandboard adhesives was studied using differential scanning calorimetry. ZB caused a separation of the addition and condensation reactions for both face and core resin (CR) systems with lowered cure temperature for the addition reaction. For the face resin, ZB did not change its nth-order curing mec...
With rapid improvements in medical treatment and health care, many datasets dealing with time to relapse or death now reveal a substantial portion of patients who are cured (i.e., who never experience the event). Extended survival models called cure rate models account for the probability of a subject being cured and can be broadly classified into the classical mixture models of Berkson and Gag...
Cumulative relative survival curves for many cancers reach a plateau several years after diagnosis, indicating that the cancer survivor group has reached "statistical" cure. Parametric mixture cure model analysis on grouped relative survival curves provide an interesting way to determine the proportion of statistically cured cases and the mean survival time of the fatal cases in particular for ...
A design sensitivity method is used to find optimal autoclave temperature and pressure histories for curing of thermoset-matrix composite laminates. The method uses a finite element simulation of the heat transfer, curing reaction, and consolidation in the laminate. Analytical sensitivities, based on the direct differentiation method, are used within the finite element simulation to find the de...
I would first like to discuss the concept of cure, because we tend to use "cure" as a general term for a variety of diseases, and I suspect that we mean different things in different situations. For example, a pneumococcal pneumonia cure is an entirely different concept from a cure in childhood acute lymphocytic leukemia, which also differs from a metastatic breast cancer cure. I believe that a...
This paper proposes, for the first time, use of an asymmetric positive and heavy-tailed distribution in a cure rate model context. In particular, it introduces cure-rate survival by assuming that time-to-event interest follows slash half-normal number competing causes event power series distribution, which defines six new models. Several properties are derived alternative expression cumulative ...
