In this work, the adsorption of the anionic dye, Congo red (CR), from aqueous solution by using tea waste (TW) has been carried out at 30 °C. The equilibrium sorption isotherms and kinetics were investigated. The equilibrium adsorption was studied by the Langmuir and Freundlich models of adsorption. The experimental results manifested that the Langmuir isotherm was the best model for the adsorp...

We present high-resolution X-ray spectra of the X-rayÈbright classical T Tauri star, TW Hydrae, covering the wavelength range of 1.5È25 The di†erential emission measure derived from Ñuxes of AŽ . temperature-sensitive emission lines shows a plasma with a sharply peaked temperature distribution, peaking at log T \ 6.5. Abundance anomalies are apparent, with iron very deÐcient relative to oxygen,...

It has recently been suggested that the winds from classical T Tauri stars in general, and the wind from TWHya in particular, reaches temperatures of 300,000 Kwhile maintaining a mass-loss rate of 10 M yr 1 or larger. If confirmed, this would place strong new requirements on wind launching and heating models. We therefore reexamine spectra from the Space Telescope Imaging Spectrograph aboard th...

Heterozygous Twirler (Tw) mice develop obesity and circling behavior associated with malformations of the inner ear, whereas homozygous Tw mice have cleft palate and die shortly after birth. Zeb1 is a zinc finger protein that contributes to mesenchymal cell fate by repression of genes whose expression defines epithelial cell identity. This developmental pathway is disrupted in inner ears of Tw/...

We propose an online convex optimization algorithm (RESCALEDEXP) that achieves optimal regret in the unconstrained setting without prior knowledge of any bounds on the loss functions. We prove a lower bound showing an exponential separation between the regret of existing algorithms that require a known bound on the loss functions and any algorithm that does not require such knowledge. RESCALEDE...

For certain classes of Prüfer domains A, we study the completion Â,T ofA with respect to the supremum topology T = sup{Tw|w ∈ Ω}, where Ω is the family of nontrivial valuations on the quotient field which are nonnegative on A and Tw is a topology induced by a valuation w ∈ Ω. It is shown that the concepts ‘SFT Prüfer domain’ and ‘generalized Dedekind domain’ are the same. We show that if E is t...

In terms of an effective Lagrangian we investigate the possibilities of probing anomalous top quark couplings, t ¯ tH, γt ¯ t, Zt ¯ t and tW b at the future linear colliders. It is found that at a linear collider with a c. m. energy √ s ∼ 0.5 − 1.5 TeV and a high luminosity of 10 − 1000 fb −1 , e + e − → t ¯ tH is an ideal process in probing anomalous t ¯ tH couplings. We also study in detail t...
