A ZPP Lifting Theorem
The complexity class ZPP (corresponding to zero-error randomized algorithms with access to one NP oracle query) is known to have a number of curious properties. We further explore this class in the settings of time complexity, query complexity, and communication complexity. r For starters, we provide a new characterization: ZPP equals the restriction of BPP where the algorithm is only allowed t...
متن کاملAmplifying ZPP and the Two Queries Problem
This paper shows a complete upward collapse in the Polynomial Hierarchy (PH) if for ZPP, two queries to a SAT oracle is equivalent to one query. That is, ZPP = ZPP =⇒ ZPP = PH. These ZPP machines are required to succeed with probability at least 1/2+ 1/p(n) on inputs of length n for some polynomial p(n). This result builds upon recent work by Tripathi [16] who showed a collapse of PH to S2 . Th...
متن کاملNuance: Adding Multi-touch Force Detection to the Ipad
NUANCE is a new device adding multi-touch force detection to the iPad touch screen. It communicates with the iPad using the audio jack input. Force information is sent at an audio rate using analog amplitude modulation (AM). NUANCE provides a high level of sensitivity and responsiveness by only using analog components. It is very cheap to make. NUANCE has been developed in the context of a larg...
متن کاملImproving re-sampling detection by adding noise
Current image re-sampling detectors can reliably detect re-sampling in JPEG images only up to a Quality Factor (QF) of 95 or higher. At lower QFs, periodic JPEG blocking artifacts interfere with periodic patterns of re-sampling. We add a controlled amount of noise to the image before the re-sampling detection step. Adding noise suppresses the JPEG artifacts while the periodic patterns due to re...
متن کاملAB12. Testosterone and prostate cancer: adding fuel to the fire?
Over the last 15 years there has been growing recognition of the benefits of testosterone supplementation therapy (TST) for men with testosterone deficiency (TD), also termed hypogonadism. These benefits include improved sexual interest and performance, improved mood, energy, increased muscle and bone density, decreased fat, and possibly improved longevity. The new interest in TST has precipita...
