Due to the XML’s flexibility and semi-structured nature, complications arise when trying to transplant data from one XML to another. Researchers have made great strides in solving the problem of integrating homogenous XML. But there are very few specifically addressing the problem of integrating heterogenous documents. We introduce XSD Matcher, a system for automatically mapping a collection of...

Recently, a novel technique called coded cache have been proposed to facilitate the wireless content distribution. Assuming the users have the identical cache size, prior works have described the fundamental performance limits of such scheme. However, when heterogenous user cache sizes is taken into account, there remains open questions regarding the performance of the cache. In this work, for ...

Invasive mole also known as chorioadenoma destruens comprises about 15 % of all gestational trophoblastic neoplasia [1]. It is a trophoblastic tumor characterized by myometrial invasion by direct extension or through venous channels. The most common presenting symptom is vaginal bleeding (97 %) [2]. The diagnosis is usually suggested after a hydatidiform mole is removed and bhCG remains elevate...

Although essential tremor (ET) has been well characterized since 1887, there is still considerable controversy about the definition of ET, and there is no agreement among the experts as to whether ET is a symptom, a syndrome, or a specific disease entity. Some experts, including my esteemed colleague, Dr. Elble, have concluded that ET “may not be a single entity.” As I agree with this view, the...

Electron Microscope is popular and powerful techniques used to characterize heterogeneous catalysts. In heterogeneous catalysis, frequently used catalysts are metal particles supported on an oxidic material. The size of the metal particles plays a crucial role for the catalyst efficiency, and the determination of size distribution is one of the main tasks of electron microscopy in catalysis. Th...

Ferrites have excellent magnetic, electric, and optical properties that make them an indispensable choice of material for a plethora applications, such as in various biomedical fields, magneto–optical displays, rechargeable lithium batteries, microwave devices, internet technology, transformer cores, humidity sensors, high-frequency media, magnetic recordings, solar energy fluids. Recently, mag...

This paper presents techniques for dynamic load balancing in heterogeneous computing environments. That is, the techniques are designed for sets of machines with varying processing capabilities and memory capacities. These methods can also be applied to homogenous systems in which the effective compute speed or memory availability is reduced by the presence of other programs running outside the...

Consider inference with a small number of potentially heterogeneous clusters. Suppose estimating the model on each cluster yields q asymptotically unbiased, independent Gaussian estimators with potentially heterogeneous variances. Following Ibragimov and Müller (2010), one can then conduct asymptotically valid inference with a standard t-test based on the q cluster estimators, since at conventi...
