Partially Composite Dynamical Dark Matter

In this paper, we consider a novel realization of the Dynamical Dark Matter (DDM) framework in which the ensemble of particles which collectively constitute the dark matter are the composite states of a strongly-coupled conformal field theory. Cosmological abundances for these states are then generated through mixing with an additional, elementary state. As a result, the physical fields of the DDM dark sector at low energies are partially composite -- i.e., admixtures of elementary and composite states. Interestingly, we find that the degree of compositeness exhibited by these states varies across the DDM ensemble. We calculate the masses, lifetimes, and abundances of these states -- along with the effective equation of state of the entire ensemble -- by considering the gravity dual of this scenario in which the ensemble constituents are realized as the Kaluza-Klein states associated with a scalar propagating within a slice of five-dimensional anti-de Sitter (AdS) space. Surprisingly, we find that the warping of the AdS space gives rise to parameter-space regions in which the decay widths of the dark-sector constituents vary non-monotonically with their masses. We also find that there exists a maximum degree of AdS warping for which a phenomenologically consistent dark-sector ensemble can emerge. Our results therefore suggest the existence of a potentially rich cosmology associated with partially composite DDM.Comment: 25 pages, LaTeX, 6 figures, 1 tabl

Study of Urban Drainage Network Performance in Maximum Discharge Storage in the City of Bandung

The analysis of Urban Drainage Network Performance in Maximum Discharge Storage in the City becomes an urgent matter, the approach that will be conducted in this research is explanatory, which is explaining natural phenomena that happened and synthesizing the relation of parameter stream, existing drainage network, and potential puddle. The result of analysis shows several inundation area in the rainy season in subCatchment Citepus, the cause is identified as there has not been a drainage channel that connects it to the main canal that caused the drainage network hard to be evaluated, the water rope are clogged beside the road, dimensional channel cannot handle runoff discharge, various clog on several crossway, the narrowing and swallowing of channel because of sedimentation, and several different utility with the transversal and parallel in position causing it to become a place where garbage stacks up. Several channel section’s capacity are unable to contain discharge, but several channel are still able to contain but in factuality of the field there are still rash that caused inundation in several main section roadway in Bandung.     Keywords: discharge, inundation, flood, drainage

Trend Analysis of Teenage Pregnancy in Nigeria (1961-2013): How Effective is the Contraceptive Use Campaign

Teenage pregnancy (TP) is a recurrent global and public health problem. It poses both social and health challenges. Considering the massive campaign on the use of modern contraceptives to prevent TP in recent decades, we assessed trends in TP in Nigeria between 1961 and 2013. Pregnancy and contraception history of 70,811 women who were at least 20 years old when the Nigerian DHS was conducted in 1990, 2003, 2008, and 2013 respectively were used for the study, and descriptive statistics, time analysis techniques and multiple logistic regression were used to analyze the data at 5% significance level. The overall prevalence of TP between 1961 and 2013 was 49.5% which fluctuated insignificantly during the studied period. The TP prevalence among women who entered adulthood in 1961 was 39.2%; it peaked in 1978 at 58.9% before its unsteady decline to 39.6% in 2012, and then rose sharply to 55.6% in 2013. We predicted TP prevalence as 49.0%, 49.9% and 51.0% in 2014, 2015 and 2016 respectively. The odds of TP were over 4 times higher in the North East and 5 times higher in the North West than in the South West. Teenagers with no education had higher odds of TP and it was higher among teenagers from the poorest households (OR=5.64, 95% CI: 5.36-5.94). Rather than reducing with the worldwide acknowledged increase in contraceptive campaigns, TP increased over the years studied. As far as TP is concerned in Nigeria, the impact of the campaign on MC use is far from being effective. To achieve the objective of fewer TPs, fewer resources should be spent on access to contraception and instead diverted to areas more likely to achieve results such as improvements in educational achievement amongst girls

Stable Ultra-thin CdTe Crystal: A Robust Direct Gap Semiconductor

Employing density functional theory based calculations, we investigate structural, vibrational and strain-dependent electronic properties of an ultra-thin CdTe crystal structure that can be de- rived from its bulk counterpart. It is found that this ultra-thin crystal has an 8-atom primitive unit cell with considerable surface reconstructions. Dynamic stability of the structure is predicted based on its calculated vibrational spectrum. Electronic band structure calculations reveal that both electrons and holes in single layer CdTe possess anisotropic in-plane masses and mobilities. Moreover, we show that the ultra-thin CdTe has some interesting electromechanical features, such as strain-dependent anisotropic variation of the band gap value, and its rapid increase under per- pendicular compression. The direct band gap semiconducting nature of the ultra-thin CdTe crystal remains unchanged under all types of applied strain. With a robust and moderate direct band gap, single-layer CdTe is a promising material for nanoscale strain dependent device applications
