Quantum Calculations on Ion Channels: Why Are They More Useful Than Classical Calculations, and for Which Processes Are They Essential?

The Early Phases of UX: Why They are Important (More than Evaluation), and What They are

Evaluation is a key activity in developing high level UX. This paper argues, however, that the early phases form the basis for UX, and evaluation should be seen only as a supportive role in ensuring UX. Four (4) main early activities are identified and their challenges briefly discussed. INTRODUCTION Good user experience (UX) and usability are key factors for successful products and systems. Fo...

Stretch-activated ion channels: what are they?

Mechanosensitive ion channels (MSCs) exist in all cells, but mechanosensitivity is a phenotype not a genotype. Specialized mechanoreceptors such as the hair cells of the cochlea require elaborate mechanical impedance matching to couple the channels to the external stress. In contrast, MSCs in nonspecialized cells appear activated by stress in the bilayer local to the channel--within about three...

Flux Caches: What Are They and Are They Useful?

In this paper, we introduce the concept of flux caches envisioned to improve processor performance by dynamically changing the cache organization and implementation. Contrary to the traditional approaches, processors designed with flux caches instead of assuming a hardwired cache organization change their cache ”design” on program demand. Consequently program (data and instruction) dynamic beha...

Needs Assessment Competencies: Are They Important for Extension Educators?

The purpose of this study was to determine the importance of eleven professional competencies related to needs assessment and program development; a secondary purpose was to identify the best time these competencies should be learned. The study followed a survey research design, in which 441 randomly selected extension educators in the North Central Region of the United States responded to a qu...
