Using a highly readable, conversational writing style, Practical Approach to Electroencephalography, 2nd Edition, makes a complex and critically important subject easier to understand. It provides just the right amount of guidance you need, explaining EEG waveforms starting with the basics, then bringing you to a sophisticated level in interpreting EEG tracings—explaining what to do, what not to do, what to look for, and what the results mean. Emphasizing pattern recognition and also why the patterns look the way they do, Dr. Libenson's approachable text focuses on the types of EEG tracings you are likely to encounter in your EEG laboratory, both in the outpatient lab and in the ICU, concentrating at first on the questions and problems encountered by the beginner and non-expert, but bringing you up to the level of an expert. - Goes beyond the technical aspects of performing EEGs by discussing the link between the EEG findings and the neurologic disorders and conditions in which they occur. - Uses numerous EEG examples with abundant labels, arrows, and annotations to help you recognize normal and abnormal EEGs in all situations. Illustrations have been carefully reviewed for clarity and optimal usefulness. - Contains new self-assessment questions that allow you to check your understanding. - Provides expert pearls from Dr. Libenson that guide you in best practices in EEG testing. - Features a user-friendly writing style from a single author that makes learning easy. - Includes a new introduction to the interpretation of invasive EEG monitoring. - Equips you to handle a wide variety of EEG situations, including the strategies used to distinguish EEG artifacts from true brain waves. - Any additional digital ancillary content may publish up to 6 weeks following the publication date.

This open access book constitutes the proceedings of the 22nd International Conference on Agile Software Development, XP 2021, which was held virtually during June 14-18, 2021. XP is the premier agile software development conference combining research and practice. It is a unique forum where agile researchers, practitioners, thought leaders, coaches, and trainers get together to present and discuss their most recent innovations, research results, experiences, concerns, challenges, and trends. XP conferences provide an informal environment to learn and trigger discussions and welcome both people new to agile and seasoned agile practitioners. This year’s conference was held with the theme “Agile Turns Twenty While the World Goes Online”. The 11 full and 2 short papers presented in this volume were carefully reviewed and selected from 38 submissions. They were organized in topical sections named: agile practices; process assessment; large-scale agile; and short contributions.
