Examining the cancellation mechanism of neutron EDM in a model with dilaton-dominated susy breaking

We examine the cancellation mechanism between the different contributions to the electric dipole moment of the neutron in a model with dilaton-dominated SUSY breaking. We find these accidental cancellations occur at few points in parameter space. For a wide region of this space we must constrain the phase of $\mu$ to be of order $10^{-1}$ and have the phases of $A$ and $\mu$ strongly correlated in order to have small neutron EDM. Moreover, we consider the indirect CP violation parameter $\epsilon$ in this region where the electric dipole moment is less than the experimental limit and find that we can generate $\epsilon$ of order $10^{-6}$

Classification of Several Skin Cancer Types Based on Autofluorescence Intensity of Visible Light to Near Infrared Ratio

Skin cancer is a Malignant growth on the skin caused by many factors. The most common skin cancers are Basal Cell Cancer (BCC) and Squamous Cell Cancer (SCC). This research uses a discriminant analysis to classify some tissues of skin cancer based on criterion number of independent variables. An independent variable is variation of excitation light sources (LED lamp), filters, and sensors to measure autofluorescence intensity (IAF) of visible light to near infrared (VIS/NIR) ratio of paraffin embedded tissue biopsy from BCC, SCC, and Lipoma. From the result of discriminant analysis, it is known that the discriminant function is determined by 4 (four) independent variables i.e., blue LED-red filter, blue LED-yellow filter, UV LED-blue filter, and UV LED-yellow filter. The accuracy of discriminant in classifying the analysis of three skin cancer tissues is 100%

Mixing of the CP Even and the CP Odd Higgs Bosons and the EDM Constraints

The mixing among the CP even and the CP odd neutral Higgs bosons of MSSM by one loop induced effects in the presence of CP phases is investigated using three different mechanisms to satisfy the EDM constraints, i.e., a fine tuning of phases, a heavy sparticle spectrum, and the cancellation mechanism. It is shown that if a mixing effect among the CP even and the CP odd Higgs bosons is observed experimentally, then it is only the cancellation mechanism that can survive under the naturalness constraint.Comment: 14 pages, Latex and 4figures.

Fluorescent light (FL), red LED and blue LED spectrums effects on in vitro shoots multiplication

Tissue culture in ornamental plants is one of the relevant factors that beat production of vegetables and fruit production worldwide. It has been recognized as an effective tool to enhance large scale of plant multiplication. However, the conventional lighting system may contain unnecessary wavelength that are low quality to promote growth. In this study, experiment was conducted by using Light Emitting Diodes (LED) as an alternative source of lighting. Red and blue LEDs along with fluorescent light (FL) were applied to determine the best source of light in multiplication of rose. Under the same media regimes which are MS media basal and BAP shoot hormone, blue LED had shown more shoots and leaves

On the EDM Cancellations in D-brane models

We analyze the possibility of simultaneous electron, neutron, and mercury electric dipole moment (EDM) cancellations in the mSUGRA and D--brane models. We find that the mercury EDM constraint practically rules out the cancellation scenario in D-brane models whereas in the context of mSUGRA it is still allowed with some fine-tuning.Comment: 10 pages, to appear in Phys.

Authenticity, identity and sustainability in post-war Iraq: reshaping the urban form of Erbil city

Issues of authenticity and identity are particularly significant in cities where social and cultural change is shaping active transformation of its urban fabric and structure in the post-war condition. In search of sustainable future, Iraqi cities are stretched between the two ends of the spectrum, authentic quarters with its traditional fabric and modern districts with their global sense of living. This paper interrogates the reciprocal influences, distinct qualities and sustainable performance of both authentic and modern quarters of Erbil, the capital of the Iraqi province of Kurdistan, as factors in shaping sustainable urban forms for Iraqi cities. In doing so, the paper, firstly, seeks to highlight the urban identity as an effective factor in relation to sustainable urban form. Secondly, the city of Erbil in Iraq has been chosen as a field study, due to its regional, social, political and historical role in the region. Thirdly, the study emphasises the dynamic activities and performance of residential projects according to rational sustainable criteria. The research concludes that urban identity and the sense of place in traditional and historical places should inform design strategies in order to achieve a more sustainable urban context

The role of urban pattern indicators for sustainable urban forms in the developed countries: a pragmatic evaluation of two sustainable urban contexts

Since cities are constantly changing, their new forms activities are developed according to their patterns and physical arrangements. Sustainable urban form is currently a widely discussed topic in the concept of urban sustainability. The physical built form of cities can be conceptualised as two interlocking planes. The first is the spatial distribution of activities and buildings. The second element is the pattern of streets, parks and the public realm. Sustainable integration between these layers lead to a compatible built environment. This paper intends to formulate sustainable urban form indicators as a conceptual framework model which provides a comprehensive understanding of how sustainability can be evaluated and measured according to the pattern of any built environment. This framework consists of eight indicators: Accessibility, Connectivity, Compatibility, Diversity, Nodality, Density, Identity, and Adaptability. Accordingly, two of the most significant sustainable urban district has been chosen as a field study. The first is Hammerby residential district in Stockholm of Sweden, and the other is Vauban residential district in Freiburg of Germany. The research concludes that the high quality performance of urban pattern indicators in the developed communities may motivate, inform and improve the design strategies in order to achieve a more sustainable urban context
