In literature and art, suspension of disbelief is the willingness of the audience to accept a premise as true even if it is not possible in the real world. Audience members must set-aside their beliefs about the world and accept one or more premises which form the foundation for the new world. Research also requires a suspension of disbelief, especially research conducted in the laboratory. In ...

Complementary infinite-impulse response (IIR) filter pairs can be synthesized to generate power-complementary, allpass complementary, or magnitude-complementary filter pairs (see, e.g., [1]). A very attractive alternative to generate a power-complementary low-pass/high-pass IIR filter pair is to use lattice wave digital (LWD) filters (parallel connections of two all-pass filters) [2]–[4]. Usual...

BACKGROUND Tests for recent infections (TRIs) are important for HIV surveillance. We have shown that a patient's antibody pattern in a confirmatory line immunoassay (Inno-Lia) also yields information on time since infection. We have published algorithms which, with a certain sensitivity and specificity, distinguish between incident (< = 12 months) and older infection. In order to use these algo...

Half-band (HB) filters are of great importance and are often used in multirate digital signal processing systems, filter banks and wavelets. In this paper, a new closed-form expression for the transfer function of the maximally flat (MF) infinite-impulse response (IIR) HB filters is presented. The filter coefficients are directly obtained by solving a linear system of Vandermonde equations that...

Purpose Mammalian central nervous system axons fail to regenerate after injury. Contributing factors include limited intrinsic growth capacity and an inhibitory glial environment. Inflammation-induced optic nerve regeneration (IIR) is thought to boost retinal ganglion cell (RGC) intrinsic growth capacity through progrowth gene expression, but effects on the inhibitory glial environment of the o...

INTRODUCTION GRAPPA [1] is one of the most popular image reconstruction methods for Parallel MRI. This method interpolates downsampled k-space data with moving average (MA) kernel estimated using a set of fully acquired Auto-Calibrating Signal (ACS) lines in kspace; consequently, its reconstruction quality depends greatly on the estimation and generality of the kernel. Improving kernel estimati...

INTRODUCTION With the increasing use of immunobiological drugs (IBD), the knowledge about their effectiveness and safety has increased. OBJECTIVE To analyze the immediate infusional reactions (IIR) to intravenous IBD: infliximab (IFX), rituximab (RTX), abatacept (ABT) and tocilizumab (TCZ) on the treatment of autoimmune diseases. METHOD 2126 infusions performed in the Infusion Centre - CID ...

1 A modi ed lattice structure with pleasant scaling properties Jean Laroche Abstract| This communication presents a modi ed lattice structure for IIR lters, which exhibits pleasant scaling properties at no additional computational or memory cost when the re ection coe cients are close to 1. With this structure, the gain at the resonance of a second-order purely-recursive section is nearly indep...
