Among other results, it is shown that any analytic space-like curve without isolated inflections can be approximately converted into a G1 spline curve composed of MPH cubics with the approximation order being equal to four.
Frequently, however, several isoglosses are grouped approximately together into a bundle of isoglosses.
This is because, for our proposed method, the weighted SR problem is approximately converted into a source beamforming decoupled one which significantly reduces the computational complexity.
After transforming the real data into the complex field, the obtained complex matrix was approximately factorized into a product of two low-rank matrices through an unconstraint complex optimization problem.
This matrix A is then approximately factorised into a weight n×k matrix W and a key-frame k×m matrix H, where k is the predefined number of key-frames.
In the latter case, it is shown that structures of the optimal source precoder and relay transceiver have closed forms, where the remaining joint power allocation problem can be approximately formulated into a Geometric Programming (GP) problem.
This work presents a new approach to Muller's ratchet, where Haigh's model is approximately mapped into a simpler model that describes the behaviour of a population after a click of the ratchet, i.e., after loss of what was the fittest class.
Since the objective problem is difficult to be solved directly, considering the high signal-to-residual-interference-plus-noise ratio (SRINR) and employing the Cauchy-Schwarz inequality and S-lemma, the problem can be approximately converted into a source beamforming decoupled one.
The observed incidence approximately translates into a 20 year risk of 1 in 85 with gastritis, 1 in 50 with atrophic gastritis, 1 in 39 with intestinal metaplasia, and 1 in 19 with dysplasia among patients who undergo gastroscopy with biopsy for clinical indications.
