The study of exoplanets is one of the most vibrant fields of astrophysics today. Precise radial velocity (RV, or Doppler) measurements created the field by discovering the first exoplanets. Although employed for more than 30 years, RV measurements are still relevant today; when used with the transit method it provides the first characterization of exoplanets in terms of its mass, radius, and bulk density. These provide the first clues as to the internal structure of the exoplanet. With this text, Hatzes provides a deep understanding of the Doppler method, including how to achieve RV measurement precision, as well as the challenges, limitations, and potential of the technique. It also covers other aspects of the method such instrumentation, wavelength calibration, finding periodic signals in RV time series, signal interpretation, and Keplerian orbits. It's an essential reference for researchers and graduate students in the field of exoplanets, and additionally stellar spectroscopists and instrumentalists.
The area of machine learning, especially deep learning, has exploded in recent years, producing advances in everything from speech recognition and gaming to drug discovery. Tomographic imaging is another major area that is being transformed by machine learning, and its potential to revolutionise medical imaging is significant. Written by active researchers in the field, Machine Learning for Tomographic Imaging presents a unified overview of deep-learning-based tomographic imaging. Key concepts, including classic reconstruction ideas and human vision inspired insights, are introduced as a foundation for a thorough examination of artificial neural networks and deep tomographic reconstruction. X-ray CT and MRI reconstruction methods are covered in detail, and other medical imaging applications are discussed. An engaging and accessible style makes this book an ideal introduction for those in applied disciplines, as well as those in more theoretical fields who wish to learn about application contexts. Hands-on projects are also suggested, and links to open source software, working datasets, and network models are included.
This book provides an insight into the global practices for environmental management of military live-fire training ranges by combining scientific research with practical solutions to ensure continued training capability. The text is divided into four parts: the first provides the background information necessary to understand the scientific principles behind environmental management. The second part comprises methodologies for the environmental risk assessment of explosives and munitions, and the third collates case studies and innovative management techniques that have been applied to reduce remediation costs. Finally, part four considers the design of greener or insensitive munitions to reduce environmental impact. This is an essential reference guide for those with a responsibility for environmental management of military training ranges, and who are required to ensure sustainable long-term training capability.<br><br>
Designed to support candidates through the training and examination scheme of bodies such as the Royal College of Radiologists, this text focuses on the aspects of anatomy that are most relevant to the achievement of fellowship status. The text is arranged in a manner to encourage learning and an understanding of the key concepts rather than just providing a vehicle to pass the exams. Each chapter consists of a series of questions typical of those found on the fellowship exams. The images and diagrams that accompany each question provide a stimulus to the concepts being challenged, whilst the answers also contain explanations that, in many instances, go beyond that strictly necessary to support the answer. Examination tips to better prepare readers are also included.
Bounty hunter Jack Keller faces his most dangerous and sadistic enemy yet in this explosive Southern thriller…Jack Keller works in fugitive apprehension, and never feels more alive than when he’s hunting down a skip.

But something in the back of her mind tells Marie not to jump to conclusions…When a bloody, merciless killing spree starts in a church on the other side of the county, it seems impossible that Keller’s skip and Marie’s murder/kidnapping case could be related. But the local media is soon involved, and the mess they make of the situation soon reveals just what Keller, Marie, and every other peace officer in the state of North Carolina doesn’t want to believe: three people are viciously angry, incredibly well armed, and they’re ready to strike again at any time.

Dominick Prince is out of options. He’s lived in Detroit long enough to use his experiences of crime and poverty to fuel his writing, but he’s ready to move on to bigger and better things. Dominick’s thesis advisor, the elitist Parker Farmington, refuses to let Dominick pass his class, thinking the genre of potboilers beneath him. Which means rather than becoming the next literary sensation, Dominick will spend his life asking customers if they’d like fries with that.

And once he has Farmington’s signature, fame and fortune are within Dominick’s grasp. But while Dominick may have a devious and brilliant mind on the page, in reality he’s more Betty White than Walter White. And before he can write ’the plot thickens,’ Dominick’s plan begins to go horribly wrong. Teaming with Farmington’s jilted mistress and her loose-cannon bounty hunter brother, Dominick finds that if even the best laid plans go awry, then his doesn’t have a snowball’s chance in hell.
