Suppose that R (red) and B (blue) are two graphs on the same vertex set of size n, H is some graph with a red-blue coloring its edges. How large can be if R∪B does not contain copy H? Call largest such integer mex(n,H). This problem was introduced by Diwan Mubayi, who conjectured (except for few specific exceptions) when complete k+1 vertices any edges mex(n,H)=ex(n,Kk+1). conjecture generalize...

Sustainability and energy efficiency of additive manufacturing (AM) is an up-to-date industrial request. Likewise, the claim for 3D-printed parts with capable mechanical strength remains robust, especially polymers that are considered high-performance ones, such as polycarbonates in material extrusion (MEX). This paper explains impact seven generic control parameters (raster deposition angle; o...

Material extrusion additive manufacturing of metal (metal MEX), which is one the 3D printing processes, has gained more interests because its simplicity and economics. Metal MEX process similar to conventional injection moulding (MIM) process, consisting feedstock preparation powder polymer binders, layer-by-layer MEX) or create green parts, debinding remove binders sintering consolidated metal...

Background—Hypoxia induces an inflammatory response in the lung manifested by alternative activation of macrophages with elevation of proinflammatory mediators that are critical for the later development of hypoxic pulmonary hypertension. Mesenchymal stromal cell transplantation inhibits lung inflammation, vascular remodeling, and right heart failure and reverses hypoxic pulmonary hypertension ...

Front Cover: When using material extrusion (MEX) method to print parts made of Polyether-ether-ketone (PEEK), due the uneven distribution temperature field and stress field, prone warping deformation. Reveals influence rules each printing parameter coupling effect between them on warpage This lays a foundation for realization PEEK denture forming by MEX. is reported Jiang Han, Ju Tong, Xiaoqing...

Andrews and Newman have recently introduced the notion of mex a partition, smallest positive integer that is not part. The concept has been used since at least 2011, though, with connections to Frobenius symbols. Recently parity associated crank statistic named by Dyson in 1944. In this note, we extend strengthen connection between (along new generaliztion mex) proving number properties natural...

Two cell lines, one proficient (Mex+) and one deficient (Mex-) in the ability to remove O6-methylguanine, have been isolated by Epstein-Barr virus-mediated transformation of a single blood sample obtained from a normal human male. Extracts of untreated cells differ in their O6-methylguanine transferase (methyl acceptor protein) activity. Although both lines arise from the same individual, they ...

Polymer science plays a crucial role in the understanding and numerical study of material extrusion processes that have revolutionized additive manufacturing (AM). This investigated impact high-gravity conditions on conducted by referring to development system (HG-MEX). In this study, we evaluated polymeric characteristics HG-MEX. By analyzing interplay between polymer behavior gravity, provide...
