High Density QCD

The dynamics of high partonic density QCD is presented considering, in the double logarithm approximation, the parton recombination mechanism built in the AGL formalism, developed including unitarity corrections for the nucleon as well for nucleus. It is shown that these corrections are under theoretical control. The resulting non linear evolution equation is solved in the asymptotic regime, and a comprehensive phenomenology concerning Deep Inelastic Scattering like $F_2$, $F_L$, $F_2^c$. $\partial F_2/ \partial \ln Q^2$, $\partial F^A_2/ \partial \ln Q^2$, etc, is presented. The connection of our formalism with the DGLAP and BFKL dynamics, and with other perturbative (K) and non-perturbative (MV-JKLW) approaches is analised in detail. The phenomena of saturation due to shadowing corrections and the relevance of this effect in ion physics and heavy quark production is emphasized. The implications to e-RHIC, HERA-A, and LHC physics and some open questions are mentioned.Comment: 41 pages, 13 figures.

Gambaran Kadar High Density Lipoprotein Darah Pada Laki-laki Berusia 40-59 Tahun Dengan Indeks Massa Tubuh ≥23 Kg/m2

: High density lipoprotein (HDL) is a lipoprotein containing apo A-1, associated with other apolipoproteins. One of the HDL functions is as the reversed transporter of cholesterol in order to reduce cholesterol level in peripheral tissues. Low HDL cholesterol level is often related to obesity. High cholesterol level, obesity, and low HDL level are known as risk factors of coronary heart diseases. Overweight subjects have higher probabality for suffering from heart diseases and stroke. This study aimed to elaborate high density lipoprotein (HDL) levels in males aged 40-59 years with body mass index higher than 23 kg/m2. This study used consecutive sampling method. Total subjects involved in this study were 20 males who lived in Malalayang. The results showed that there were 11 subjects with normal HDL levels and nine subjects (45%) with low HDL levels (<45 mg/dL). No subjects had high HDL level. Nineteen subjects (95%) were classified as obesity and only one subject (5%) as overweight. Conclusion: Most of the males 40-59 aged with body mass index ≥23 kg/m2 who lived in Malalayang Manado has normal HDL level

High-density molecular characterization and association mapping in Ethiopian durum wheat landraces reveals high diversity and potential for wheat breeding

Durum wheat (Triticum turgidum subsp. durum) is a key crop worldwide, and yet, its improvement and adaptation to emerging environmental threats is made difficult by the limited amount of allelic variation included in its elite pool. New allelic diversity may provide novel loci to international crop breeding through quantitative trait loci (QTL) mapping in unexplored material. Here, we report the extensive molecular and phenotypic characterization of hundreds of Ethiopian durum wheat landraces and several Ethiopian improved lines. We test 81 587 markers scoring 30 155 single nucleotide polymorphisms and use them to survey the diversity, structure, and genome-specific variation in the panel. We show the uniqueness of Ethiopian germplasm using a siding collection of Mediterranean durum wheat accessions. We phenotype the Ethiopian panel for ten agronomic traits in two highly diversified Ethiopian environments for two consecutive years and use this information to conduct a genome-wide association study. We identify several loci underpinning agronomic traits of interest, both confirming loci already reported and describing new promising genomic regions. These loci may be efficiently targeted with molecular markers already available to conduct marker-assisted selection in Ethiopian and international wheat. We show that Ethiopian durum wheat represents an important and mostly unexplored source of durum wheat diversity. The panel analysed in this study allows the accumulation of QTL mapping experiments, providing the initial step for a quantitative, methodical exploitation of untapped diversity in producing a better wheat

Regular maps of high density

A regular map is a surface together with an embedded graph, having properties similar to those of the surface and graph of a platonic solid. We analyze regular maps with reflection symmetry and a graph of density strictly exceeding 1/2, and we conclude that all regular maps of this type belong to a family of maps naturally defined on the Fermat curves x^n+y^n+z^n=0, excepting the one corresponding to the tetrahedron.Comment: 13 pages, 4 figure
