Objective: The present study examined oscillatory brain activity of the EEG gamma band and event-related potentials (ERPs) with relation to the difficulty of a visual discrimination task. Methods: Three tasks with identical stimulus material were performed by 9 healthy subjects. The tasks comprised a passive control task, and an easy and a hard visual discrimination task, requiring discriminati...

While elevated levels of proinflammatory cytokines are clearly associated with preterm birth, the relation between cytokines and fetal growth is unclear. The authors examined associations between umbilical cord serum cytokine concentrations and risk of small-for-gestational-age (SGA) and preterm birth. This cross-sectional analysis was nested within a National Institute of Child Health and Huma...

OBJECTIVE To determine the accuracy of the Gamma G7 (and G5 model) and XXL-LF aneroid sphygmomanometers developed by the Heine Company. DESIGN Device evaluations were performed using the new protocol of the European Society of Hypertension. Monitor performance was assessed in relation to participants' sex, age, arm circumference, and systolic and diastolic blood pressures. METHODS The two s...

Motor endplates of frog semitendinosus muscles were studied under voltage clamp. Current fluctuations induced by iontophoretic application of acetylcholine were analyzed to give the elementary conductance, gamma , and mean open time, tau , of endplate channels. Total replacement of the external Na+ ion by several other metal ions and by many permeant organic cations changed both gamma and tau ....

The attentional blink (AB) is an impairment of attention, which occurs when subjects have to report a target stimulus (T2) following a previous target (T1) with a short delay (up to 600 ms). Theories explaining the AB assume that processing of T2 is more vulnerable to decay or substitution, as long as attention is allocated to T1. Existing models of the AB, however, do not account for the fact ...

We classify the coefficients $$(a_1, \ldots , a_n) \in {\mathbb {F}}_q[t]^n$$ that appear in a linear relation $$\sum _{i=1}^n a_i \gamma _i =0$$ among Galois conjugates $$\gamma \overline{{\mathbb {F}}_q(t)}$$ . call such an n-tuple Smyth tuple. Our main theorem gives affirmative answer to function field analogue of 1986 conjecture (J Numb Theory 23, 243–254, 1986) over $${\mathbb {Q}}$$ showe...

Gamma ray burst afterglows can be identified in single epoch observations using three or more optical filters. This method relies on color measurements to distinguish the power law spectrum of an afterglow from the curved spectra of stars. Observations in a fourth filter will further distinguish between afterglows and most galaxies up to redshifts z ≈ 1. By allowing faster identification of opt...

We generalize the next-to-leading order (NLO) QCD calculations for decay rates of $h\ensuremath{\rightarrow}gg$ and $h\ensuremath{\rightarrow}\ensuremath{\gamma}\ensuremath{\gamma}$ to case anomalous couplings Higgs boson. demonstrate how this computation can be done in a consistent way within framework an electroweak chiral Lagrangian, based on systematic power counting. It turns out that no a...

Recent measurements of cosmic-ray electron and positron fluxes by PAMELA and ATIC experiments may indicate the existence of annihilating dark matter with large annihilation cross section. We discuss its possible relation to other astrophysical/cosmological observations : gamma-rays, neutrinos, and big-bang nucleosynthesis. It is shown that they give stringent constraints on some annihilating da...

In the paper, we clarify some relations between solutions to star-triangle equation via gauge/YBE correspondence. We consider two relation in terms of Euler's gamma function. derive these from reduction certain basic and hyperbolic hypergeometric integral identities. These identities can be interpreted as equality supersymmetric partition functions a specific three-dimensional N=2 dual theories.
