We provide a modification to the quantum phase estimation algorithm (QPEA) inspired on classical windowing methods for spectral density estimation. From this we obtain an upper bound in cost that implies cubic improvement with respect algorithm's error rate. Numerical evaluation of costs also demonstrates improvement. Moreover, similar techniques, detail iterative projective measurement method ...
We report a case of orbital sarcoidosis in a 66 year old male who presented with one month history of right eye swelling and intermittent diplopia. MRI revealed an enhancing infiltrative soft tissue mass in the inferior aspect of the right orbit and biopsy of the mass demonstrated non-necrotizing granulomas. Chest CT scan was normal and PET scan showed no other organ involvement. He was treated...
Abstract: I study the financial distress recently experienced by the emerging market economies (EME). I distinguish two periods: Summer 2013, when there was talk about the Fed tapering monetary policy (the “taper-talk” period), and December 2013–January 2014, when the actual tapering began (the “actual-taper” period). Consistent with previous work, I find that current account deficits and real ...
A new tapered and false branched morphotype of filamentous heterocytous cyanobacterium was isolated from soil material collected on a massif of Chirripó Mountain, Costa Rica. The strain was analyzed morphologically and a sequence of its 16S rRNA gene was compared with available 16S rDNA sequences of organisms with similar morphology, especially those with heteropolar tapering filaments. Phyloge...
Toeplitz covariance matrices are used in the analysis of stationary stochastic processes and a wide range of applications including radar imaging, target detection, speech recognition, and communications systems. In this paper, we consider optimal estimation of large Toeplitz covariance matrices and establish the minimax rate of convergence for two commonly used parameter spaces under the spect...
We have experienced a Takayasu arteritis (TA) patient, successfully treated with infliximab, who did not respond well to conventional therapy with glucocosteroid and methotrexate. Takayasu arteritis had developed in a 24-year-old woman (March 2003) who had been treated with glucocorticoid including methylprednisolone pulse therapy and methotrexate; however, she relapsed during the tapering of t...
Detoxification, the initial step in the treatment of opiate dependence (Freedman, 1980) has been facing difficulties in our country as the widely used drug methadone is not available. Earlier practices were either abrupt withdrawal or gradual tapering of the dose of the opiate to which the individual was dependent. Recently clonidine has been used with success for detoxification and treatment o...
