BACKGROUND Perceived spatial intervals between successive flashes can be distorted by varying the temporal intervals between them (the "tau effect"). A previous study showed that a tau effect for visual flashes could be induced when they were accompanied by auditory beeps with varied temporal intervals (an audiovisual tau effect). METHODOLOGY/PRINCIPAL FINDINGS We conducted two experiments to...

The chemical composition, and antimicrobial and anti-wood-decay fungal activities of the essential oils isolated from the leaves and twigs of Litsea acutivena of Taiwan were investigated. The essential oils from the fresh leaves and twigs were isolated using hydrodistillation in a Clevenger-type apparatus, and characterized by GC-FID and GC-MS. Ninety-five and fifty-two compounds were identifie...

Accumulation of tau into neurofibrillary tangles is a pathological consequence of Alzheimer's disease and other tauopathies. Failures of the quality control mechanisms by the heat shock proteins (Hsps) positively correlate with the appearance of such neurodegenerative diseases. However, in vivo genetic evidence for the roles of Hsps in neurodegeneration remains elusive. Hsp110 is a nucleotide e...

We present a methodology to construct efficient high-order in time accurate numerical schemes for class of gradient flows with appropriate Lipschitz continuous nonlinearity. There are several ingredients the strategy: exponential differencing (ETD), multi-step (MS) methods, idea stabilization, and technique interpolation. They synthesized develop generic $k^{th}$ order linear scheme help an art...

We study the volatility time series of 1137 most traded stocks in the U.S. stock markets for the two-year period 2001-2002 and analyze their return intervals tau , which are time intervals between volatilities above a given threshold q . We explore the probability density function of tau , P_(q)(tau) , assuming a stretched exponential function, P_(q)(tau) approximately e;(-tau;(gamma)) . We fin...

Although primary cultures of neurons are essential methods for cell biological and pharmacological researches, many animals must be sacrificed for each experiment. Here we introduce a novel system to cryopreserve hippocampal granule cells (GCs) prepared from postnatal rats. Being thawed after as long as 60 days of cryopreservation, GCs expressed the mature neuronal marker MAP-2 and elongated si...

Sufficiently inclusive observables in the decay of the tau lepton can be calculated using the methods of perturbative QCD. These include the asymmetry parameter Aτ that determines that angular distribution of the total hadron momentum in the decay of a polarized tau. It should be possible to measure Aτ accurately using existing data from LEP. Reliable estimates of theoretical errors are essenti...

Several mutations in the gene encoding the microtubule-associated protein tau are responsible for the formation of neurofibrillary inclusions in frontotemporal dementia with Parkinsonism linked to chromosome 17 (FTDP-17). Here we present the high-resolution characterization of the conformational properties of two FTDP-17 mutants of the four-repeat domain of tau, P301L and DeltaK280, and their p...

This study was designed to examine the chemical composition of essential oil and the in vitro antimicrobial activities of essential oil and methanol extract of Teucrium montanum. The inhibitory effects of essential oil and methanol extracts of T. montanum were tested against 13 bacterial and three fungal species by using disc-diffusion method. GC/MS analyses revealed that essential oil contains...
