objective: silybin is a polyphenol with anti-oxidant and anti-cancer properties. the poor bioavailability of some polyphenols can be improved by binding to phosphatidylcholine. in recent years, studies have been conducted to evaluate the anti-cancer effect of silybin. we studied the effect of silybin and silybin-phosphatidylcholine on esr1 and esr2 gene expression and viability in the t47d brea...

abstract physical injuries during taekwondo competitions often happen due to physical contacts during fighting; therefore, a training protocol was designed in line with the physiological stress of a real competition according to la, hr and rpe changes so that the athletes could perform the techniques with a pad instead of a real opponent. for this purpose, 12 professional taekwondo players from...

Line Balancing (LB) is a classic, well-researched Operations Research (OR) optimization problem of significant industrial importance. It is one of those problems where domain expertise does not help very much: whatever the number of years spent solving it, one is each time facing an intractable problem with an astronomic number of possible solutions and no real guidance on how to solve it in th...

We investigate the structure of shift-invariant spaces generated by a finite number of compactly supported functions in Lp(R) (1 ≤ p ≤ ∞). Based on a study of linear independence of the shifts of the generators, we characterize such shift-invariant spaces in terms of the semi-convolutions of the generators with sequences on Z. Moreover, we show that such a shiftinvariant space provides Lp-appro...

Let A be a real line arrangement in P(R), and let AC be its complexification. Let CC be the complement P (C) \ ⋃ AC. Let G be the Galois group of C/R. We construct a G-equivariant 2-dimensional strong deformation retract of CC. As an application, we give an explicit presentation of the orbifold fundamental group π1(CC//G), and deduce from it an explicit presentation of the ordinary fundamental ...

We construct an increasing sequence of Borel subsets of R, such that their union is R, but R cannot be covered with countably many translations of one set. The proof uses a random method.
