We show that for each integer g ≥ 0 there is a constant cg > 0 such that every graph that embeds in the projective plane with sufficiently large face–width r has crossing number at least cgr 2 in the orientable surface Σg of genus g. As a corollary, we give a polynomial time constant factor approximation algorithm for the crossing number of projective graphs with bounded degree.
A two-year experiment was carried out at Shenyang Agricultural University’s research field area in China to evaluate the impact of combined application straw mulch (0 and 8 t ha−1) biochar (0, 4, 12, 36 on morphological traits grain development rainfed maize during 2018 2019. The results showed that different rates significantly impacted growth index. Compared non-biochar-treated soils, introdu...
The 2015−2016 El Niño was one of the strongest on record, but its influence carbon balance is less clear. Using Northern Hemisphere atmospheric CO2 observations, we found both detrended growth rate (CGR) and seasonal-cycle amplitude (SCA) were much higher than that other events. simultaneous high CGR SCA unusual, because our analysis long-term observations at Mauna Loa revealed a significantly ...
With the development of additive manufacturing (AM), Ti-6Al-4V alloy manufactured by laser powder bed fusion (LPBF) is becoming more widely studied. Fatigue fracture main failure mode such components. During LPBF processing, porosity defects are unavoidable, which hinders exploration relationship between fatigue performance and microstructure. In this study, a remelting method was used to reduc...
A new method to determine entropic profiles in DNA sequences is presented. It is based on the chaos-game representation (CGR) of gene structure, a technique which produces a fractal-like picture of DNA sequences. First, the CGR image was divided into squares 4-m in size (m being the desired resolution), and the point density counted. Second, appropriate intervals were adjusted, and then a histo...
An experiment was conducted in the experimental field of Rajshahi University Campus, Bangladesh during the rabi season of 2004-2005 to study the growth attributes of four varieties of barley (BARI Barley-1, BARI Barley-2, BHL-3, BL-1) in relation to different soil moisture regimes and NPK fertilizers. Three levels of irrigation (I0, I1, I2) and four levels of NPK fertilizers (F0, F1, F2, F3) we...
Hepatosplenic T-cell lymphoma (HSTL) is an aggressive lymphoma cytogenetically characterized by isochromosome 7q [i(7)(q10)], of which the molecular consequences remain unknown. We report here results of an integrative genomic and transcriptomic (expression microarray and RNA-sequencing) study of six i(7)(q10)-positive HSTL cases, including HSTL-derived cell line (DERL-2), and three cases with ...
This study analyzed the compound growth rate (CGR) and contributions of yield area to cassava production output in Nigeria. In these analyses, factored into consideration, each periods, triennium beginning (TB) ending (TE). During period, TB 1970 – TE 1995, oscillated between 10.7t/ha (TE 1972) 10.6 t/ha (TB 1996). At this CGR for (0.7%), (10.8%) (11.5%) were positive. The decomposition analysi...
