Simple, Near-Optimal Quantum Protocols for Die-Rolling
No full textDie-rolling is the cryptographic task where two mistrustful, remote parties wish to generate a random D-sided die-roll over a communication channel. Optimal quantum protocols for this task have been given by Aharon and Silman (New Journal of Physics, 2010) but are based on optimal weak coin-flipping protocols which are currently very complicated and not very well understood. In this paper, we first present very simple classical protocols for die-rolling which have decent (and sometimes optimal) security which is in stark contrast to coin-flipping, bit-commitment, oblivious transfer, and many other two-party cryptographic primitives. We also present quantum protocols based on the idea of integer-commitment, a generalization of bit-commitment, where one wishes to commit to an integer. We analyze these protocols using semidefinite programming and finally give protocols which are very close to Kitaev's lower bound for any D >= 3

Near-field radiative heat transfer across nanometer vacuum gaps : fundamentals and applications /
No full textNear-Field Radiative Heat Transfer across Nanometer Vacuum Gaps provides an in-depth description of fundamentals and application of near-field radiative heat transfer. When the vacuum gap between two media is on the order of nanometers, heat transfer can exceed that between blackbodies. This book investigates near-field heat transfer between different materials and geometries highlighting interplay between optics, material thermophysical properties and electromagnetism. The book also highlights the application of near-field thermal radiation in the field of power generation, imaging, and thermal systems as an analog of electronic devices.Near-Field Radiative Heat Transfer across Nanometer Vacuum Gaps provides an in-depth description of fundamentals and application of near-field radiative heat transfer.

Motion of quantum vortex lines near realistic rough boundaries
No full textWe numerically solve the three--dimensional, time--dependent Gross--Pitaevskii equation to model a superfluid flowing over a realistic rough boundary. Our model for the boundary is based on the atom--force microscope image of a NbTi vibrating wire used to generate turbulence in actual experiments. We find that near the boundary a dense region of quantum vortices is created, which forms a kind of `superfluid boundary layer'
Predicting the response of small-scale near-wall turbulence to large-scale outer motions
No full textThe paper deals with the question of how to determine – or “predict” - the near-wall-turbulence statistics from a Reynolds-number-independent, “universal”, small-scale signal, and the Reynolds-number-dependent large-scale outer motions in the log layer. An empirical model is proposed, which is intended to take into account the effect of “splatting”, not previously considered, thus offering an improved representation of the near-wall-turbulence field
Detecting intestinal ischemia using near infrared spectroscopy
No full textBlood supply to the intestine can suddenly be interrupted. Acute mesenteric intestinal ischemia often requires invasive surgery to restore blood supply to the intestine. Early correction of vascular insufficiency is the most important factor in improving patient survival when confronted with acute mesenteric intestinal ischemia. A prolonged loss of blood flow results in irreversible damage to the intestine that can lead to death. It is also imperative that dead segments of the intestines be removed. Several subjective criteria are relied upon to differentiate viable from non-viable tissue, unfortunately, these criteria can lead to an inaccurate assessment. A porcine model of intestinal ischemia was used to determine the efficacy of using near infrared (NIR) spectroscopy to find ischemic segments of the intestine and detect the onset of reperfusion following resolution of vascular occlusion. Nine segments of intestine were identified and six were assigned to three treatment groups; (1) segments undergoing no vascular manipulations, (2) segments undergoing arterial/venous occlusion and (3) segments undergoing arterial/venous occlusion followed by reperfusion. The remaining segments were used as spacers and interposed between each of the ischemia segments. A classification model, using partial least square discriminant analysis, was built on the spectra collected from the segments with no vascular manipulations and the segments that were solely subjected to arterial/venous occlusion. The spectra collected from the intestinal segments that experienced both occlusion and reperfusion were used to test the classification model. The model was able to detect and distinguish ischemic intestinal tissue with a specificity and sensitivity exceeding 80% with an overall classification accuracy of 89%. The method appears to be well suited as an intra-operative assessment method when intestinal ischemia is a concern.Michael G. Sowa, Elicia Kohlenberg, Jeri R. Payette, Lorenzo Leonardi, Michelle A.

No full textArticle asserting that the field of near-death studies needs to embrace other models and groups of professionals if it hopes to understand the near-death phenomenon. According to the author, no one can validate a near-death experience (NDE) except the experiencer; it is the aftereffects that impart real meaning to the experience and give it greater impact, and the "classical NDE model" that guides most near-death research can be limiting and misleading
