The quantity N5(n) is the maximum length of a finite sequence over n symbols which has no two identical consecutive elements and no 5-term alternating subsequence. Improving the constant factor in the previous bounds of Hart and Sharir, and of Sharir and Agarwal, we prove that N5(n) < 2nα(n) +O(nα(n) ), where α(n) is the inverse to the Ackermann function. Quantities Ns(n) can be generalized and...

Myeloid malignancies are characterized by an extreme molecular heterogeneity, and many efforts have been made in the past decades to clarify the mechanisms underlying their pathogenesis.In this scenario SET binding protein 1 (SETBP1) has attracted a lot of interest as a new oncogene and potential marker, in addition to its involvement in the Schinzel-Giedon syndrome (SGS). Our review starts wit...

Quasielastic neutron scattering, x-ray diffraction measurements, and fully atomistic molecular dynamics simulations have been performed on poly(vinylpyrrolidone) homopolymer above its glass transition temperature. A "prepeak" appears in the x-ray diffraction pattern that shows the typical features of a first amorphous halo. From an effective description of the experimentally accessed incoherent...

In this paper we initiate a systematic study of the Turán problem for edge-ordered graphs. A simple graph is called if its edges are linearly ordered. This notion allows us to graphs (and in particular their maximum number edges) when subgraph forbidden with specific edge-order but same underlying may appear different edge-order. We prove an Erd?s-Stone-Simonovits-type theorem graphs—we identif...

the effects of a nano-emulsion chitosan-based coating on enhancing the shelf-life and quality of golab kohanz apples were studied. the nano-emulsion coating containing chitosan with a concentration of 2000 ppm was applied for coating of golab kohanz apples. coated and uncoated apples were packed in normal packaging cardboards and kept at 2 ± 1 °c with a relative humidity within 80-85%. flesh fi...
