Given 0 < p < 1, we prove that a pseudo-random graph G with edge density p and sufficiently large order has the following property: Consider any red/blue-colouring of the edges of G and let r denote the proportion of edges which have colour red. Then there is a Hamilton cycle C so that the proportion of red edges of C is close to r. The analogue also holds for perfect matchings instead of Hamil...

Using a series of digital image processing methods, such as gray stretch, median filter, threshold segmentation, edge extraction and detection, detect the variations of red blood cells, realize the goal of identifying the shapes of variable red blood cells, and good results have been achieved. In conclusion, the average detection rate of abnormal red blood cells is above 80 %. This inspiring an...

‎‎let $g=(v,e)$ be a simple graph‎. ‎an edge labeling $f:eto {0,1}$ induces a vertex labeling $f^+:vtoz_2$ defined by $f^+(v)equiv sumlimits_{uvin e} f(uv)pmod{2}$ for each $v in v$‎, ‎where $z_2={0,1}$ is the additive group of order 2‎. ‎for $iin{0,1}$‎, ‎let‎ ‎$e_f(i)=|f^{-1}(i)|$ and $v_f(i)=|(f^+)^{-1}(i)|$‎. ‎a labeling $f$ is called edge-friendly if‎ ‎$|e_f(1)-e_f(0)|le 1$‎. ‎$i_f(g)=v_f(...

With the growth of Industrial Internet, various types data show explosive growth. Data is being moved from cloud to edge for computing more frequently and becomes an important factor affecting deep application Internet platforms. However, security issue transmission sharing not addressed. Therefore, this paper proposes a scheme based on timed-release, multi-dimensional virtual permutation, prox...

Flavonoid biosynthesis profile was clarified by fruit bagging and re-exposure treatments in the green Chinese pear 'Zaosu' (Pyrus bretschneideri Rehd.) and its red mutant 'Red Zaosu'. Two distinct biosynthesis patterns of flavonoid 3-glycosides were found in 'Zaosu' pear. By comparison with 'Red Zaosu', the biosynthesis of flavonoid 3-galactosides and flavonoid 3-arabinosides were inhibited by ...

Liver transplantation is the treatment of choice in selected patients with end-stage liver disease. Postoperative complications often require surgical re-intervention. This study is a retrospective single-centre study to assess the incidence and type of surgical re-intervention during the in-hospital period after liver transplantation and to identify predictors of this re-intervention. From 199...
