Is that really worth it – assuring value

Evolving neural networks: Is it really worth the effort?

The idea of using simulated evolution to create neural networks that learn faster and generalize better is becoming increasingly widespread. However, such evolutionary processes are usually extremely computationally intensive. In this paper, I present an empirical study to investigate whether the improved performance obtained really does justify the extra effort, and whether it might be possibl...

Imaging of parathyroid lesions with radionuclides - Is it worth doing?

Parathyroid adenomas, or hyperplasia may be present in patients with hypercalcemia. Treatment Is by surgical excision, but about 10% of the lesions may be In ectopic locations. Pre-operative localization of the lesions with non-lvasive imaging, using radionuclides, ultrasound, CT, or MR], may simplify surgery, and reduce patient morbidity. However, the reports of the accuracy of the curre...

Statistical significance: is it really that significant?

parallel import: is it worth?

one of the most important duties of government in public health sector is to provide secured sources for medicines supply. there are some regulations for domestic pharmaceutical industry. in addition, there is a discipline for importing medicine to be ensured about their claimed characteristics. in medicines registration process, moh (fdo in iran) assess ‘safety’, ‘quality’ and ‘efficacy’ of me...

Tolerance--is it worth it?

We are entering an exciting time in the study of immunologic tolerance. Several cellular and molecular strategies have been developed that show promise in nonhuman transplant models and these approaches are just now appearing in clinical trials. Tolerance strategies that prevent immune rejection and obviate the need for immunosuppressive medications (with inherent risk of cancer, infection, and...
