A general method for the one-pot, three-component Strecker reaction of ketones was developed using Brønsted acids as organocatalysts. A series of alpha-aminonitriles were obtained in good to excellent yields (79-99%). A preliminary extension to a catalytic enantioselective three-component Strecker reaction of ketones (up to 40% ee) is also described.

Monitoring the temperature of a semiconductor component allows for prediction potential failures, optimization selected cooling system, and extension useful life component. There are many methods measuring crystal element referred to as die. The resolution accuracy measurements depend on chosen method. This paper describes known imaging distribution die surface device. Relationships also descri...

Component-based development helps to improve the modularity and reusability of embedded systems. Component models devised for embedded systems are typically restricted due to the limited computing, storage and power resources of the target systems. Most existing component models for embedded systems therefore only support a static component architecture and provide a simple and lightweight core...

The recent paper (Cheung 2001) has studied the blind identification of Gaussian source process through a general temporal independent component analysis (ICA) approach named dual autoregressive modelling. It is actually a temporal extension of the classical principal component analysis without considering the principal order of the components. In this paper, we will further show the identifiabl...

Software deployment is an inevitable part of software lifecycle. For non-component-based software, there already exist generic tools and environments supporting fully automated deployment. However, for component-based software, there has not been any unified environment and/or suit of tools performing deployment activities yet. This paper proposes such an environment and presents a generic comp...

A new set of boundary-handling algorithms has been developed for discrete wavelet transforms in the ISO/IEC JPEG-2000 Still Image Coding Standard. Two polyphase component extrapolation policies are specified: a constant extension policy and a symmetric extension policy. Neither policy requires any computations to generate the extrapolation. The constant extension policy is a low-complexity opti...

BACKGROUND Diabetes education presents two major challenges to the U.S. Cooperative Extension System. The first is that the majority of diabetes education services are provided in more populated areas, resulting in large nonurban areas being underserved. The second is that many individuals with diabetes find the meal-planning component of diabetes education confusing. CONTEXT The University o...

PURPOSE It is not clear how the knee extension torque is distributed quantitatively among the lateral and medial vasti in patellofemoral pain (PFP) patients with patellar malalignment, which was investigated in vivo and noninvasively in ten PFP patients and eleven controls. We hypothesized that the vastus medialis oblique (VMO) and vastus medialis longus (VML) of PFP patients contribute less to...
