It is widely accepted that meaningful learning is associated with motivation. It is also widely assumed that learning will eventuate if the process is fun. The English philosopher John Locke (1968) once said, more than 300 years ago, that it would be desirable to make learning a play or recreational activity rather than an assigned task or a have-to-do business. In other cultural settings, this...

Although pricing strategy in marketing is a crucial issue, there islittle literatureon the relationship between pricing and sellers’ reputation based on dynamic pricing data. Using data on Taobao.com, we compare pricing behaviors of two types of sellers, business sellers (T-Mall sellers) which have higher reputation and individual sellers (Tao sellers) which have relatively lower reputation. We...

Tetraarsenic oxide (As4O6, TAO) is a new arsenic compound that inhibits cell growth and induces apoptosis in human cervical cancer cell lines. In the present study, we report that the growth of tumor cells (CaSki) was inhibited by treatment with TAO alone or in combination with cisplatin or paclitaxel in vitro and in vivo. Proliferation was assess...

Thyroid-associated ophthalmopathy (TAO) is a potentially severe autoimmune disease, in and around the orbit, usually accompanied by Graves' disease. It was the goal of this study to develop a serological indicator for TAO and to characterize its expression in human thyroid and eye muscle tissue. Thus, we have recloned the full-length 1D-complementary DNA and assessed its expression levels in 90...

There exists an absolute constant δ > 0 such that for all q and all subsets A ⊆ Fq of the finite field with q elements, if |A| > q2/3−δ , then |(A−A)(A−A)| = |{(a− b)(c − d) : a, b, c, d ∈ A}| > q 2 . Any δ < 1/13, 542 suffices for sufficiently large q. This improves the condition |A| > q2/3, due to Bennett, Hart, Iosevich, Pakianathan, and Rudnev, that is typical for such questions. Our proof ...

We prove that spectral projections of Laplace-Beltrami operator on the m-complex unit sphere E∆ S2m−1 ([0, R)) are uniformly bounded as an operator from H(S) to L(S) for all p ∈ (1,∞). We also show that the Bochner-Riesz conjecture is true when restricted to cylindrically symmetric functions on R × R. Suppose that L is a positive definite, self-adjoint operator acting on L(X,μ), where X is a me...

This paper describes methods used in stabilizing the walking gait of Tao-Pie-Pie, a small humanoid robot given rate feedback from two RC gyroscopes. Tao-Pie-Pie is a fully autonomous small humanoid robot (30cm tall). Although Tao-Pie-Pie uses a minimal set of actuators and sensors, it has proven itself in international competitions, winning honors at the RoboCup and FIRA HuroSot competitions in...

Thyroid-associated ophthalmopathy (TAO) is a condition associated with a wide spectrum of ocular changes, usually in the context of the autoimmune syndrome, Graves' disease. In this topical review, we attempted to provide a roadmap of the recent advances in current understanding the pathogenesis of TAO, important aspects of its clinical presentation, its impact on the ocular surface, describe t...

Abstract The main aim of the article is to evaluate gas potentiality for post-Messinian megasequence in TAO Field, North Sinai Concession, offshore Nile Delta Basin. detailed petrophysical analysis three deviated wells study area (Tao-3 ST1 Well, Tao-5 STA Well and Tao-7 Well) revealed that Pliocene Kafr El-Sheikh Formation includes eleven gas-bearing zones. These zones were named: A, B, C Tao-...
