Suppose that f = QeP where Q is a real rational function and P is a polynomial, not necessarily real, and that f has only real zeros. We prove that then P(z) = az2 + bz + c where a 0 and b is real, or f (z) = AeBz where A and B are nonzero complex constants.doi:...

Nonnegative matrix factorization (NMF) is widely used to analyze high-dimensional count data because, in contrast to real-valued alternatives such as factor analysis, it produces an interpretable parts-based representation. However, in applications such
Similarly, we prove the distance between two consecutive zeros t1 and t2 with u negative on]t1, t2 [is such that t2−t1⩾πv with equality if and only if q (t) = – v on [t1, t2]. It follows that b−a⩾t2−t0⩾πμ+πv=b−a. This implies t2 –t0 = b– a,...
The system corresponding to B has an infinite number of solutions since the third column has no pivot entry, and its corresponding variable can take on any real value. (The complete solution set for this system is {(−1−2c,4−3c,c,2)|c∈ℝ}.) However, the system corresponding...
Insert zeros to upsample the signal byp. Apply an FIR antialiasing filter to the upsampled signal. Discard samples to downsample the filtered signal byq. The ideal antialiasing filter has normalized cutoff frequencyfc=π/max(p,q)rad/sample and gainp. To approximate the antialiasing filter,resam...
This demixing effect leads to the accumulation of larger particles (for n≤4 in our study) in different regions along the direction of shear: the zeros of the shear-rate for conctact-dominated suspesions, positive shear-rate for electochemical potentials-dominated interactions. It is important ...
Compositional data arise in many real-life applications and versatile methods for properly analyzing this type of data in the regression context are needed
