We have obtained the first high spatial (0. ′′ 05) and spectral (R ∼ 35000) resolution 2 µm spectrum of the T Tau S tight binary system using adaptive optics on the Keck II telescope. We have also obtained the first 3.8 and 4.7 µm images that resolve the three components of the T Tau multiple system, as well as new 1.6 and 2.2 µm images. Together with its very red near-infrared colors, the spec...

The Witten–Kontsevich theorem states that a certain generating function for intersection numbers on the moduli space of stable curves is a tau-function for the KdV integrable hierarchy. This generating function can be recovered via the topological recursion applied to the Airy curve x = 1 2 y 2. In this paper, we consider the topological recursion applied to the irregular spectral curve xy2 = 2...

The MESUR solar array power model initially uses assumed values for many input variables. After landing the early surface variables such as array tilt and azimuth or early environmental variables such as array temperature can be corrected. Later environmental variables such as tau versus time, spectral shift, dust depotion, and UV darkening are dependent upon time, on-board science instruments,...

We study the evolution and emission of circumbinary disks around close classical T Tauri binary systems. High resolution numerical hydrodynamical simulations are employed to model a system consisting of a central eccentric binary star within an irradiated accretion disk. A detailed energy balance including viscous heating, radiative cooling and irradiation from the central star is applied to ca...

Tau is one of several types of microtubule-associated proteins (MAPs), responsible for the assembly and stability of microtubule networks that is present only in neurons and predominantly localized in axons which its functions are tightly regulated by phosphorylation. Via as yet unknown mechanisms, tau becomes hyperphosphorylated and accompanies with neuronal degeneration, loss of synapses...

A topoframe, denoted by $L_{ tau}$, is a pair $(L, tau)$ consisting of a frame $L$ and a subframe $ tau $ all of whose elements are complementary elements in$L$. $f$-ring $mathcal{R}(L_{ tau})$ is equal to the set $${fin Frm(mathcal{P}(mathbb R), L): f(mathfrak{O}(mathbb R))subseteq tau} .$$ In this paper, for every complemented element $ain L$ with $a, a'...

We present spatially-resolved X-ray observations of the binary T Tauri star system V710 Tau. Using Chandra’s Advanced CCD Imaging Spectrometer (ACIS), we imaged this 3.2 separation binary system, consisting of a classical T Tauri star, V710 Tau N, and a weak-lined T Tauri star, V710 Tau S. The Chandra ACIS-S3 images — obtained in two 9 ks exposures separated by about three months (2004 December...

it is well-known that dam-reservoir interaction has significant effects on the response of dams to the earthquakes. this phenomenon should be considered more exactly in the seismic design of dams with a rational and reliable dynamic analysis method. in this research, seismic analysis of the dam-reservoir is studied as a wave propagation problem by using legendre spectral element method (sem). t...

The talk covers three contributions on (i) the final measurement of branching ratios and spectral functions of τ decays using the full LEP-I data from ALEPH, (ii) a preliminary measurement of the τ hadronic branching ratios from DELPHI and (iii) a measurement of the strange spectral function in hadronic τ decays from OPAL. These measurements are discussed and the relevant physics topics are bri...

Stiffness manifests in stochastic dynamic systems in a more complex manner than in deterministic systems; it is not only important for a time-steppingmethod to remain stable but it is also important for the method to capture the asymptotic variances accurately. In the context of stochastic chemical systems, time stepping methods are known as tau leaping. Well known existing tau leaping methods ...
