We have developed an analytical formula for the cure progress of epoxy systems as a function of both time t and temperature T. Complex viscosity h* or the storage modulus G' are used as the measures of the cure progress. The equation is based on the shape of the isothermal viscosity vs. time curves typically found for thermoset systems; temperature dependence of the isothermal parameters is est...

The FernUniversität in Hagen uses the web-based collaborative learning platform CURE to implement different collaborative learning scenarios such as seminars or lab courses. In these scenarios, students form groups and collaboratively solve tasks given by the teachers. Interviews with students that have used CURE showed major interest in using CURE nomadically without the need for permanent int...

We extend the Dahlberg and Wang (Biometrics 2007, 63, 1237-1244) proportional hazards (PH) cure model for the analysis of time-to-event data that is subject to a cure rate with masked event to a setting where the PH assumption does not hold. Assuming an accelerated failure time (AFT) model with unspecified error distribution for the time to the event of interest, we propose rank-based estimatin...

Only one person in the world has been cured of HIV. The Berlin patient was transplanted with CCR5-negative and HIV-resistant stem cells for cancer that eradicated his HIV. Reported in 2009, the case renewed interest in the search for a cure. But what has happened in the ensuing years? In 2013, apparent HIV remission (ie, undetectable plasma viral load in the absence of antiretroviral therapy or...

BACKGROUND Survival analysis methods such as the Kaplan-Meier method, log-rank test, and Cox proportional hazards regression (Cox regression) are commonly used to analyze data from randomized withdrawal studies in patients with major depressive disorder. However, unfortunately, such common methods may be inappropriate when a long-term censored relapse-free time appears in data as the methods as...

BACKGROUND There are no published reports on studies comparing itraconazole (ITC), sulfamethoxazole-trimethoprim (cotrimoxazole, CMX), and ITC followed by CMX (ITC/CMX) in the treatment of paracoccidiodomycosis. This study aimed to compare the efficacy, effectiveness, safety and time to clinical and serologic cure in paracoccidioidomycosis patients treated with ITC or CMX, the antifungal agents...

This research investigates the effect of post-cure time on residual stresses in laminated composites. Laminated composites were made of T300 carbon fibers and epoxy resin. The post-cure process was carried out at the constant temperature of 120 °C for 6 and 12 hours for two specimens. The slitting method was employed to determine through-thickness residual stress distribution of the composite l...
