There is an error in the first three sentences under the subheading “Cut-Off value of SpO2” in the Results section. The correct sentences are: We hypothesized that the cut-off value of each pulse oximeter to detect hypoxemia (SaO2< = 90% or PaO2< = 60 mmHg) was different. We calculated the sensitivity, specificity, PPV, and NPV of each pulse oximeter to detect hypoxemia. As shown in Table 5, th...

The symmetric cut-off rate is derived for Quadrature-Amplitude-Modulated (QAM) block-coded data-transmissions over noisy links impaired by timecorrelated multipath-phenomena which give rise to Rayleigh-distributed randomly time-variant Intersymbol Interference (ISI) effects. The presented formulas for the cut-off rate are new; they are derived from a random coding bound developed “ad hoc” for b...

Following a strategy introduced earlier by the authors, we show that it is possible to extract |Vub| from the cut hadronic mass spectrum of B decays without large systematic errors which usually arise from having to model the Fermi motion of the heavy quark. We present a closed form expression for |Vub|/|Vts| which is accurate up to corrections of order α 2 s, αsρ, (Λ/mb) 2/ρ, where ρ is the ex...

We describe some observations on the practical implementation of the median cut color quantization algorithm, suitably modified for accurate color rendering. The RGB color space is successively divided in such a way that colors with visual significance, even if relatively small in population, are given representatives in the colormap. Appropriately modified, median cut quantization is nearly as...

We extend the Blum and Chawla (2001) graph min-cut algorithm to structured problems. This extension can alternatively be viewed as a joint inference method over a set of training and test instances where parts of the instances interact through a prespecified associative network. The method has has an efficient approximation through a linear-programming relaxation. On small training data sets, t...

Normalized cut is a widely used measure of separation between clusters in a graph. In this paper we provide a novel probabilistic perspective on this measure. We show that for a partition of a graph into two weakly connected sets, V = A B, the multiway normalized cut is approximately MNcut ≈ 1/τA→B + 1/τB→A, where τA→B is the unidirectional characteristic exit time of a random walk from subset ...

In this paper, we present explicit and computable error bounds for the asymptotic expansions of Hermite polynomials with Plancherel–Rotach scale. Three cases, depending on whether scaled variable lies in outer or oscillatory interval, it is turning point, are considered separately. We introduce ‘branch cut’ technique to express terms as integrals contour taken one-sided limit curves approaching...

Let G be a minimal imperfect P 5-free graph (i.e. a minimal imperfect graph not containing a path on 5 vertices as induced subgraph) and let S be a minimal cutset of G. In this paper we study several properties of such cutsets, in particular we prove that the subgraph induced by S is connected, contains a P 4 , cannot induce a bipartite subgraph of G .... As a by-product we also give a structur...

The repair bandwidth of a code is the minimum amount of data required to repair one or several failed nodes (erasures). For MDS codes, the repair bandwidth is bounded below by the so-called cut-set bound, and codes that meet this bound with equality are said to support optimal repair of one or multiple failed nodes. We consider the problem of repairing multiple failed nodes of Reed-Solomon (RS)...
