The Dantzig selector performs variable selection and model fitting in linear regression. It uses an L1 penalty to shrink the regression coefficients towards zero, in a similar fashion to the Lasso. While both the Lasso and Dantzig selector potentially do a good job of selecting the correct variables, they tend to over-shrink the final coefficients. This results in an unfortunate trade-off. One ...

We describe a simple approach to the controlled removal of molecules from the membrane of large unilamellar vesicles made of fatty acids. Such vesicles shrink dramatically upon mixing with micelles composed of a mixture of fatty acid and a phospholipid (1-palmitoyl-2-oleoyl-sn-glycero-3-phosphocholine (POPC)), as fatty acid molecules leave the vesicle membrane and accumulate within the mixed mi...

Websites often use ‘wrap contracts — clickwrap and browsewrap agreements — which include provisions that permit websites to track and exploit customer information. In this paper, I propose that the law conceptualize a website user’s act of inputting or uploading information as constituting a limited license to the website to use the information for very expressly defined purposes. Websites that...

This paper presents the dilemma of e-commence age that huge amount of computer –related litigation challenges the law of different countries on how to appropriately resolve these difficulties. Through this paper, the author tries to compare UCITA and EU with China’s approaches, seeks for guidance or inspiration for policymakers in China. The author seriously examines the conflicting interests a...

Image denoising using wavelet transform has been successful as wavelet transform generates a large number of small coefficients and a small number of large coefficients. Basic denoising algorithm that using the wavelet transform consists of three steps – first computing the wavelet transform of the noisy image, thresholding is performed on the detail coefficients in order to remove noise and fi...
