A novel adaptive multiple dependent state sampling plan (AMDSSP) was designed to inspect products from a continuous manufacturing process under the accelerated life test (ALT) using both double (DSP) and (MDSSP) concepts. Under conditions, lifetime of product follows Weibull distribution with known shape parameter, while scale parameter can be determined acceleration factor (AF). The Arrhenius ...

BACKGROUND In clinical trials, both unequal randomization design and sequential analyses have ethical and economic advantages. In the single-stage-design (SSD), however, if the sample size is not adjusted based on unequal randomization, the power of the trial will decrease, whereas with sequential analysis the power will always remain constant. Our aim was to compare sequential boundaries appro...

Cyclooxygenase is involved in the biosynthesis and function of prostaglandins. It is a glycoprotein located in the endoplasmic reticulum and in the nuclear envelope, and it has been found to have two isoforms termed COX-1 and COX-2. This paper reports on the glycosylation site analysis of recombinant COX-2 using matrix-assisted laser desorption/ionization (MALDI) time-of-flight (TOF) mass spect...

Phase III trials aim to assess whether a new treatment has superior efficacy than a standard treatment. Sequential methods, such as the sequential probability ratio test (SPRT), the triangular test (TT) and so-called one-parameter boundaries (OPB), now allow early stopping of such trials, both in the case of efficacy (alternative hypothesis; H(1)) and in the case of lack of efficacy (null hypot...

Sample average approximation (SAA) is a widely popular approach to data-driven decisionmaking under uncertainty. Under mild assumptions, SAA is both tractable and enjoys strong asymptotic performance guarantees. Similar guarantees, however, do not typically hold in finite samples. In this paper, we propose a modification of SAA, which we term Robust SAA, which retains SAA’s tractability and asy...
