I test the practicality of ideal stabilization. Self-stabilization, or classic stabilization, is a specification property which guarantees that a program will eventually satisfy its specification regardless of transient faults or lack of initialization. Classic stabilization loses some appeal as a new standard for fault tolerant distributed systems due to unattractive features such as poor comp...

Light and gibberellins (GAs) antagonistically regulate hypocotyl elongation in plants. It has been demonstrated that DELLAs, which are negative regulators of GA signalling, inhibit phytochrome-interacting factors 3 and 4 (PIF3 and PIF4) by sequestering their DNA-recognition domains. However, it is unclear whether there are other mechanisms of regulatory crosstalk between DELLAs and PIFs. Here, ...

In this paper, vehicle relative positioning applied in Vehicle-to-Infrastructure (V2I) navigation is described. GPS positioning augmented with Ultra-Wideband (UWB) ranges is reviewed. The relative solution is implemented in an extended Kalman filter where differential GPS pseudorange, Doppler and carrier phase measurements are used in conjunction with UWB ranges measured between the vehicle and...

Cronobacter (formerly known as Enterobacter sakazakii) is a genus comprising seven species regarded as opportunistic pathogens that can be found in a wide variety of environments and foods, including powdered infant formula (PIF). Cronobacter sakazakii, the major species of this genus, has been epidemiologically linked to cases of bacteremia, meningitis in neonates, and necrotizing enterocoliti...

10 volumes of Luria–Bertani (LB) medium containing Tet and Kn and grown to saturation. To begin the third positive selection, a 25 ml GMML culture containing Tet, Kn, and 1 mM pIF, pAF, pCF, or OAY was inoculated with cells from the negative screen (100 μl, pelleted and resuspended in GMML). After incubation for 3 h at 37°C, Cm was added to a final concentration of 75 μg/ml, and cells were grow...

This paper presents an automated fuzziness-driven algorithm for image enhancement. A class of parametric indices of fuzziness is introduced, which serves as the optimization criterion of the contrast-enhancement procedure. We show that the parametric class of indices constitutes a one-parameter generalization of the linear index of fuzziness of a set. The modification of the membership values o...

Objective: Preimplantation-factor (PIF) is a new peptide with many potential functions. We aimed to compare the maternal serum PIF levels among early-onset preeclamptic patients healthy controls at same gestational age. Patients and Methods: Thirty-nine (< 34 weeks) 45 expecting women have been added our study. or suspicion of any chronical disease, diabetes, twin pregnancies, fetal plac...

An analytic signal permits unambiguous characterization of the phase and envelope of a real signal. But the analytic signal's phase-derivative i.e. the instantaneous frequency (IF) is typically a wild function and can take on values ranging fron negative in nity to positive in nity. Fortunately, any analytic signal can be decomposed into a minimum phase (MinP) signal component and an all-phase ...
