Discover the secrets behind your restless nights and uncover the hidden marvels of your slumbering mind. Are you tossing and turning at night? Drifting off during the day? You might have a sleep problem. Geared toward everyone from sleep-deprived students to active athletes to young-at-heart grandparents, this book will help you understand your sleep like never before, covering common sleep problems such as: sleepwalkingsleep apneanot enough sleepoverly drowsy during the dayAnd discussing the various impacts of disordered sleep on life including: the effects of aging on sleep and memorysleep and heart healthsleep's impact on weight and blood pressuresleep and athletic performanceWritten by distinguished physician, H. Kenneth Fisher, Sleep: A User's Guide will help you understand what causes the problems you face and how you can get better, more reliable sleep.

A compendium of practical information vital to avoidance of unexpected problems during ship design, construction, repair and conversion based on thousands of professional interviews and other sources.

In this thesis, I present experimental results demonstrating the characterization of a planar Paul trap. I discuss the theory of ion trapping and analyze the voltages required for shuttling. Next, the characteristics of a digital-to-analog converter (DAC) are calibrated, and this instrument is integrated into trapping experiments to test the viability of the analytic model. Combining theory with the capabilities of the DAC, I calculate that the new experimental system is capable of 3 nm-precision control of the ion. Taking advantage of this ion control, I present initial results for a lock-in micromotion detection method which minimizes stray fields around an 88Sr+ ion using Fourier analysis on the ion fluorescence to detect resonance at the secular frequencies. This method drives the ion oscillator across resonance using a superimposed radiofrequency electric field, which allows for off-axis field measurements as well as trap characterization. With this method, the secular frequencies of the trap are measured and are observed to fall within 3.50[sigma] of the analytic prediction.

The Only Three Questions That Count is the first book to show you how to think about investing for yourself and develop innovative ways to understand and profit from the markets. The only way to consistently beat the markets is by knowing something others don’t know. This book will show you how to do just that by using three simple questions. You’ll see why CNBC’s Mad Money host and money manager James J. Cramer says, "I believe that reading his book may be the single best thing you could do this year to make yourself a better investor. In The Only Three Questions That Count, Ken Fisher challenges the conventional wisdoms of investing, overturns glib theories with hard facts, and blows up complacent beliefs about money and the markets. Ultimately, he says, the key to successful investing is daring to challenge yourself and whatever you believe to be true. Packed with more than 100 visuals, usable tools, and a glossary, The Only Three Questions That Count is an entertaining and educational experience in the markets unlike any other, giving you an opportunity to reap the huge rewards that only the markets can offer.

The generalized covariant entropy bound, or Bousso bound, is a holographic bound on the entropy of a region of space in a gravitational theory. It bounds the entropy passing through certain null surfaces. The bound remains nontrivial in the weak-gravity limit, and provides non-trivial constraints on the entropy of ordinary quantum states even in a regime where gravity is negligible. In the first half of this thesis, we present a proof of the Bousso bound in the weak-gravity regime within the framework of quantum field theory. The bound uses techniques from quantum information theory which relate the energy and entropy of quantum states. We present two proofs of the bound in free and interacting field theory. In the second half, we present a generalization of the Bousso bound called the quantum focussing conjecture. Our conjecture is a bound on the rate of entropy generation in a quantum field theory coupled semiclassically to gravity. The conjecture unifies and generalizes several ideas in holography. In particular, the quantum focussing conjecture implies a bound on entropies which is similar to, but subtly different from, the Bousso bound proven in the first half. The quantum focussing conjecture implies a novel non-gravitational energy condition, the quantum null energy condition, which gives a point-wise lower bound on the null-null component of the stress tensor of quantum matter. We give a proof of this bound in the context of free and superrenormalizable bosonic quantum field theory.
