The xanthophyll cycle (Xc), which involves violaxanthin de-epoxidase (VDE) and the zeaxanthin epoxidase (ZEP), is one of the most rapid and efficient responses of plant and algae to high irradiance. High light intensity can activate VDE to convert violaxanthin (Vx) to zeaxanthin (Zx) via antheraxanthin (Ax). However, it remains unclear whether VDE remains active under low light or dark conditio...

The ZX-calculus was introduced as a graphical language able to represent specific quantum primitives in an intuitive way. recent completeness results have shown the theoretical possibility of purely description processes. However, practice, such approaches are limited by intrinsic low level nature ZX calculus. scalable notations been proposed attempt recover higher point view while maintaining ...

OBJECTIVES The aim of this in-vitro study was to compare the accuracy of two new electronic apex-locator controlled handpieces (EALHs) using the first rotary Mtwo file while rotating in the canal. MATERIALS AND METHODS A total of 36 extracted mandibular molar teeth were selected. The lengths of the mesio-buccal canals to the major foramina were measured directly using a size 10 K-file introdu...

Let B = (Bt)t≥0 be a standard Brownian motion started at zero, and let μ ∈ R be a given and fixed constant. Set B t = Bt+μt and S t = max 0≤s≤t B s for t ≥ 0 . Then the process: (x ∨ Sμ)−Bμ = ((x ∨ S t )−B t )t≥0 realises an explicit construction of the reflecting Brownian motion with drift −μ started at x in R+ . Moreover, if the latter process is denoted by Z = (Z t )t≥0 , then the classic Lé...

Let A be a C*-algebra. Let z be the maximal atomic projection in A∗∗. By a theorem of Brown, x in A∗∗ has a continuous atomic part, i.e. zx = za for some a in A, whenever x is uniformly continuous on the set of pure states of A. Let L be a closed left ideal of A. Under some additional conditions, we shall show that for any x in A∗∗, x has a continuous atomic part modulo L∗∗, i.e. zx + L∗∗ = za ...
