Self-dual Chern-Simons solitons in noncommutative space

We construct exact soliton solutions to the Chern-Simons-Higgs system in noncommutative space, for non-relativistic and relativistic models. In both cases we find regular vortex-like solutions to the BPS equations which approach the ordinary selfdual non-topological and topological solitons when the noncommutative parameter $\theta$ goes to zero.Comment: 15 pages, 4 figure

Resonant Higgs boson pair production in the hh→bbˉ WW→bbˉℓ+νℓ−νˉhh\rightarrow b\bar{b} \; WW \rightarrow b\bar{b} \ell^+ \nu \ell^- \bar\nu decay channel

Adding a scalar singlet provides one of the simplest extensions of the Standard Model. In this work we briefly review the latest constraints on the mass and mixing of the new Higgs boson and study its production and decay at the LHC. We mainly focus on double Higgs production in the $hh \rightarrow b \bar{b} WW \rightarrow b \bar{b} \ell^+ \nu \ell^- \bar{\nu}$ decay channel. This decay is found to be efficient in a region of masses of the heavy Higgs boson of 260 - 500 GeV, so it is complementary to the 4$b$ channel, more efficient for Higgs bosons having masses greater than 500 GeV. We analyse this di-leptonic decay channel in detail using kinematic variables such as $M_{\rm T2}$ and the $M_{\rm T2}$-assisted on-shell reconstruction of invisible momenta. Using proper cuts, a significance of $\sim$ 3$\sigma$ for 3000 fb$^{-1}$ can be achieved at the 14 TeV LHC for $m_H$ = 260 - 400 GeV if the mixing is close to its present limit and ${\rm BR}(H \rightarrow hh) \approx 1$. Smaller mixing values would require combining various decay channels in order to reach a similar significance. The complementarity among $H \rightarrow hh$, $H \rightarrow ZZ$ and $H \rightarrow WW$ channels is studied for arbitrary ${\rm BR}(H \rightarrow hh)$ values.Comment: 36 pages, 13 figure

New natural gas pipeline benefits Europe and Africa

European countries have agreed to start filling up their natural gas gap, with the new natural gas pipeline from Africa. Nigeria and Morocco agreed to develop this pipeline in 2016, but after the beginning of the Ukraine-Russia war, things have speeded up. After the economical punishments Europe imposed on Russia, Russia decided to increase the price of the natural gas exported to Europe and decrease the amount of gas. Most European countries have a big dependency on Russia\u27s natural gas, countries like Germany import 50% of their natural gas from Russia. Since winter is coming up, European countries are dealing with having to go back and use carbon as an energy source or look for ways to import natural gas from different countries. And this project seems like the best option for this situation

Debilidades en la aplicación de las políticas públicas de cobertura para la educación superior del Chocó

Los sectores más pobres se enfrentan a una oferta educativa limitada, lo que impide que una gran población termine su educación media y que como consecuencia lo excluye de la educación superior -- La culminación de los estudios secundarios no es una garantía para poder continuar estudios universitarios, lo que hace que de las zonas más pobres obtengan puntajes muy bajos en las pruebas de Estado (ICFES) , lo cual responde a dos factores según Gabriel Misas Arango en su libro la Educación Superior en Colombia : “En primera medida por la baja calidad de la educación recibida, determinada entre otros, por la existencia de establecimientos con pocos recursos educativos, profesores mal remunerados y una organización institucional profundamente burocratizada que desestimulo los procesos de mejoramiento en la calidad. Además la baja escolaridad en sus entorno familiar, causa que tiene la mayor influencia en la creación de las diferencias en los puntajes del ICFES, entre los egresados de los establecimientos públicos de las zonas antes señaladas y los egresados de los establecimientos privados que provienen de las capas medias altas de la población, grupo que constituye la mayoría de la matrícula universitaria, y cuenta con entornos familiares altamente escolarizados -- ” (Misas, 2004, pág. 57) -- Permitiéndonos dilucidar que la educación está dada por sectores y que sobre todo la entrada a las universidades no llega a los estratos menos favorecidos, dándose una clasificación y limites a un derecho social que tiene características generales, lo que nos llevó a estudiar sobre las Políticas Públicas de Cobertura para la Educación Superior en el Chocó en los periodos comprendidos entre los años 2010 y 2013, permitiéndonos observar su comportamient

The Next Vaccine Generation Against Malaria: Structurally Modulated Plasmodium Antigens

Challenges for obtaining more effective malaria vaccines depend on precise selection of antigenic motifs and understanding the complexity of Plasmodium spp. life cycle. Naturally expressed antigens are characterized for being weak immunogenic when tested as vaccine components, thus these have to be strategically modified to render them immunogenic. A molecular clue in this pursuit is provided by the chemical peptide-bond processing by peptidases, which follows a multistep pathway including ephemeral high energy molecular complexes known as transition states. Thus, we have proposed non-natural peptide-bond isosteres as transition states mimetics, and therefore, stabilizing these high-energy states with site-directed designed immuno-mimetics have demonstrated being a rational approach for stimulating antibody populations harboring multiple functional capacities. Therefore, peptide-bond substitutes constitute a coherent pathway towards obtaining selected immuno-active compounds from specific plasmodial molecular objectives. Chemical strategies for synthesizing peptido-mimetics and antimalarial selected trials lead us to assess a number of peptide-bond substitutes for obtaining immuno-active and structurally defined molecules. Plasmodium antigens expressed on merozoite, sporozoite and gametocyte stages have been selected as targets and subsequently modified based on the presence of either a high-binding motif or a potential HLA-reading frame. This new family of immuno-mimetics is and efficient neutralizing antibody inducers when tested in in vitro and in vivo experiments, thus representing a new generation of malaria vaccine components

Estimation of productivity change of NBA teams from 2006-07 to 2012-13 seasons

"... acknowledgements at FiT Publishing"The aim of this work is to evaluate the productivity change of the NBA teams during the last seven seasons (from 2006-07 to 2012-13). Within that period of time, a new collective bargaining agreement (CBA) of the National Basketball Association (NBA) was ratified before season 2011-12, ending a 161-day lockout. The Malmquist Productivity Index (MPI) has been used to measure the total factor productivity, while an input-oriented Network DEA approach is used to compute the distance of each observation to the corresponding frontier. The results reveal that there has been technological progress for the last few seasons, excluding that of the 2011 lockout, and an increasing efficiency change. This means that best practices are improving and that most teams have been reducing their payrolls to catch up with these practices, thus backing up the owners’ proposal to reduce players’ income. Also regression results show that changes in the number of wins are more dependent upon scale efficiency change than upon budget or efficiency changes
