On Authentication, Digital Signatures and Signature Laws [PDF]
, 1999 The public debate arising from the introduction of signature laws in North America, Europe and elsewhere has prompted this paper. This paper analyses and compares the closely interrelated concepts of authentication, digital signatures and electronic signature laws and tries to explain and resolve some of the ambiguities. Non-trivial problems and issues

Comprehensive clinical evaluation of novel 4DCT‐based lung function imaging methods
Journal of Applied Clinical Medical Physics, EarlyView.Abstract Purpose Methods have been developed that apply image processing to 4DCTs to generate 4DCT‐ventilation/perfusion lung imaging. Traditional methods for 4DCT‐ventilation rely on Hounsfield‐Unit (HU) density‐change methods and suffer from poor numerical robustness while not providing 4DCT‐perfusion data.

An Introduction to Digital Signature Schemes [PDF]
arXiv, 2014 Today, all types of digital signature schemes emphasis on secure and best verification methods. Different digital signature schemes are used in order for the websites, security organizations, banks and so on to verify user's validity. Digital signature schemes are categorized to several types such as proxy, on-time, batch and so on.

Subthalamic Nucleus Oscillatory Characteristics in Meige, Cervical Dystonia and Generalized Dystonia
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Deep brain stimulation offers a unique opportunity to record neural activity of the basal ganglia. While much work in dystonia has focused on the globus pallidus internus, expanding research to investigate subthalamic nucleus (STN) activity in various dystonia types is critical to provide a comprehensive understanding of dystonia ...

Breaking novel and lightweight digital s ignature scheme
Tongxin xuebao, 2013 The signature schemes based on RSA and ECC do not seem suitable for special application area such as wire-less sensor network, smart card and wireless RFID since they suffer from low computing efficiency.
