The intrinsic laryngeal muscles cricothyroid (CT) and thyroarythenoid (TA) differ in myosin expression. CT expresses limb myosin heavy chains (MyHCs) and TA expresses an MyHC found in extraocular (EO) muscles, in addition to limb isoforms. We used immunohistochemical (IHC) analyses with highly specific monoclonal antibodies (MAbs) against various MyHCs to study muscle fiber types in rat CT and ...

The approximation numbers of Hardy–type operators on trees. Abstract The Hardy operator Ta on a tree Γ is defined by (Taf)(x) := v(x) x a u(t)f (t)dt for a, x ∈ Γ. Properties of Ta as a map from L p (Γ) into itself are established for 1 ≤ p ≤ ∞. The main result is that, with appropriate assumptions on u and v, the approximation numbers an(Ta) of Ta satisfy (*) lim n→∞ nan(Ta) = αp Γ |uv|dt for ...

In Theorem 6.1 of [3] it was shown that, when v = r+ c− 1, every triple array TA(v, k, λrr, λcc, k : r × c) is a balanced grid BG(v, k, k : r×c). Here we prove the converse of this Theorem. Our final result is: Let v = r+ c− 1. Then every triple array is a TA(v, k, c− k, r− k, k : r × c) and every balanced grid is a BG(v, k, k : r × c), and they are equivalent.

We have implemented a numerical code (ReLPM, Real Leja Points Method) for polynomial interpolation of the matrix exponential propagators exp (∆tA)v and φ(∆tA)v, φ(z) = (exp (z) − 1)/z. The ReLPM code is tested and compared with Krylov-based routines, on large scale sparse matrices arising from the spatial discretization of 2D and 3D advection-diffusion equations.

Formation of self-assembled monolayers (SAMs) of thioctic acid (TA) on polycrystalline gold electrodes has been investigated. The Au electrodes are polished, first mechanically and subsequently electrochemically, until the roughness of the surface is minimal. The best TA SAMs are formed onto these electropolished electrodes from stirred solutions, while a potential E = 0.0 V or E = +0.2 V versu...

X-ray diffraction analysis of the alloy system Co-Ni-Cr-Ta showed that the ternary alloy base consisted of three phases (a, ,8, and v-). Addition of Ta caused a decrease in the intensity of the 3 lines. Further Ta additions caused diffraction lines characteristic of the intermetallic compound a-Co3Ta. At higher Ta concentrations, the intensity of the lines characteristic of the aphase increased...
