Background: Neck mass is one of the most common clinical findings in all age groups. Differential diagnosis of masses includes a range of pathologies from congenital to infectious or neoplasm. Understanding the risk factors of neck masses can help us to assess them properly. The purpose of this study is to obtain the epidemiological and clinical features of different neck masses in Kerman, Iran...

To perform fast addition operation, CSLA is one of the fastest adders used in many dataprocessing processors. There is further scope of improving the performance parameters of CSLA. This paper provides a comparative analysis of CSLA and reviews about various proposed schemes used to reduce the delay time, area occupied and power consumption in CSLA.

664 Whose life is it anyway? Helen Lester A TALE OF THREE PRACTICES I have the privilege, or to rephrase, am mad enough each week to work in three general practices. Each practice could be considered to be located at the tip of an equilateral triangle with each line measuring around 3 miles. Three miles is not far when we think of distance, in fact I can and often walk between the three. While ...

ne of the great computing revolutions of our time has been the dramatic reduction in size of processing components and the power they consume , making mobile computing a reality. The term mobile computer spans many types of devices, from laptop or notebook computers—now central to much of our work—to the smallest cell phones, which can not only provide a mundane telephone connection but also se...

We carry out a detailed numerical investigation of the spatial correlation function of the initial positions of cosmological dark matter halos. In this Lagrangian coordinate system, which is especially useful for analytic studies of cosmological feedback, we are able to construct cross-correlation functions of objects with varying masses and formation redshifts and compare them with a variety o...

Framework-based Object-Oriented applications are not as eecient as they could be. This results from the high-genericity of frameworks. However, once the framework is instantiated, part of this genericity can be removed. This is for instance the case when gener-icity is obtained through the use of reeection. This paper takes the Java Serialization framework as a typical example and shows how par...
