When using control charts to monitor manufacturing processes, Shewhart control chart is known to be useful for detecting transient shifts, while the EWMA and CUSUM charts are useful for detecting persistent shifts. The efficiency of EWMA chart in monitoring location parameter can be improved by using an auxiliary variable that is closely related to the variable of interest. In this paper, an EW...

To see whether estrus was really “lost” during human evolution (as researchers often claim), we examined ovulatory cycle effects on tip earnings by professional lap dancers working in gentlemen's clubs. Eighteen dancers recorded their menstrual periods, work shifts, and tip earnings for 60 days on a study web site. A mixed-model analysis of 296 work shifts (representing about 5300 lap dances) s...

Gardner and colleagues [1] recently reviewed the evidence for shifts in body size as a third major response to climate change, in addition to widely recognized shifts in the ranges and phenology of species [2]. The authors conclude that, although a pattern of declining body size is commonly observed (i.e. [3]), increases in body size might also occur and more detailed studies are needed [1]. Al...

Temporal control of behavior was investigated within the framework of an internal clock model. Pigeons were exposed to signaled fixed-interval 30-s trials mixed with extended unreinforced (baseline) trials. On unreinforced break trials, the signal was interrupted for a period of time after trial onset. In Experiment 1, comparisons between the peak time obtained on baseline and on break trials p...

Recently, Yu, Brown, and Chuang [Phys. Rev. A 71, 032341 (2005)] investigated the entanglement attainable from unitary transformed thermal states in liquid–state nuclear magnetic resonance (NMR). Their research gave an insight into the role of the entanglement in a liquid–state NMR quantum computer. Moreover, they attempted to reveal the role of mixed–state entanglement in quantum computing. Ho...

Far-red fluorescent proteins are critical for in vivo imaging applications, but the relative importance of structure versus dynamics in generating large Stokes-shifted emission is unclear. The unusually red-shifted emission of TagRFP675, a derivative of mKate, has been attributed to the multiple hydrogen bonds with the chromophore N-acylimine carbonyl. We characterized TagRFP675 and point mutan...

This comparative study aimed at finding out the types of grammatical shifts which have occurred in two English translations of the Quranic rhetorical questions, and the impact of such shifts on the said rhetorical questions. For these purposes, the study firstly analyzed the Arabic and English texts syntactically using the x-bar theory for Haegeman (2006) and then classified the grammatical shi...

The phonon and vtbratlonal exciton spectra are suggested as criteria for true solid solutions of molecular crystals. The short range character o f the interactions that determine both the p h o n o n and excl ton properties makes these bands ideal for distinguishing between truly random mLxed lattices and segremated microscopic domains. Raman studies o f the chemical13, mixed p-dichlorobenzene-...

Neuroglia interactions are essential for the nervous system and in the retina Müller cells interact with most of the neurons in a symbiotic manner. Glutathione (GSH) is a low-molecular weight compound that undertakes major antioxidant roles in neurons and glia, however, whether this compound could act as a signaling molecule in neurons and/or glia is currently unknown. Here we used embryonic av...
