Autoregressive (AR) models have been the workhorse for parametric spectral estimation since they form a dense set in the class of continuous spectra and, in many cases, they approximate parsimoniously the spectrum of a given random process [1], Chap.
In the subsequent section, we give a short treatment of the TF representation of a signal along with the quadratic class of smoothed spectra.
Precisely, in [10], based on the criteria of the mutual information (MI) and minimum mean-square error (MMSE) estimation, the minimax robust waveform design has been addressed by leveraging the a priori knowledge of target power spectral density lying in an uncertainty class of spectra-bounded and signal-independent interference statistics.
Nitazoxanide 2-acetolyloxy-N- 5-nitroo 2-acetolyloxy-N- 5-nitroNTZ) represents the parent compound of a novel class of broad-spectrum anti-parasitic compounds named thiazolides.
Further modifications of 7d could lead to greater potency and selectivity metrics resulting in a new class of broad-spectrum anthelmintic.
Binary offset carrier (BOC) describes a class of spread-spectrum modulations recently introduced for the next generation of global navigation satellite systems (GNSSs).
Nucleotide-binding oligomerization domain protein 1 (Nod1) agonists have been shown to boost the inflammatory responses against pathogenic microbes and could thus constitute a new class of broad spectrum antimicrobial agents.
Antimicrobial peptides (AMPs) are a class of broad-spectrum antibiotics known by their ability to disrupt bacterial membranes and their low tendency to induce bacterial resistance, arising as excellent candidates to fight bacterial infections.
Moreover, IBR2 effectively inhibits the proliferation of CD34+ progenitor cells from CML patients, suggesting that small molecule inhibitors of RAD51 may provide a novel class of broad-spectrum therapeutics for difficult-to-treat cancers (Zhu et al., 2013).
More recently, an animal study found that in contrast to vancomycin, fidaxomicin (a new class of narrow spectrum macrocyclic antibiotic drugs) treatment caused minimal disruption of the intestinal flora and did not increase the rate of VRE and extended-spectrum β-lactamase-producing Klebsiella pneumoniae (ESBL-Kp) colonization [72].
