We present an application of the methods recently developed for the study of quasicrystal structures to the analysis of multiperiodicity of semiregular variables. A light curve analysis of UW Her shows frequencies that can be included within the general scheme characterizing the fourier spectra of fibonacci quasiperiodic sequences. The analysed data come from the BAA Variable Star Section computerised archive.

There are around 15 million preterm newborns(PT) eve ry year(Atienza-Navarro et al., 2020).With these figures in mind,prematurity represents a major health problem worldwide and it is a leading cause of infant mortality,accounting for up to 35%of all deaths among newborns(Atienza-Navarro et al.,2020) and up to 18% of the deaths among children under 5 years of age.

Understanding the biological parameters of some triatomine subspecies of Meccus phyllosomus （Burmeister） is a crucial first step in estimating the epidemiologie importance of this group. Biological parameters related to hatching, lifetime, number of blood meals to molt, percentage of females at the end of the cycle, number of laid eggs, and mortality for each instar of 3 M. phyllosomus subspecies [M. p. mazzottii （Usinger）, M. p. pallidipennis （Stal）, and M. p. phyllosomus] and their laboratory hybrids were evaluated and compared. No significant differences （P 〉 0.05） were found among the experimental hybrids （MaPa, MaPhy, PaPhy） and reciprocal cohorts. In 5 （hatching, number of blood meals to molt, accumulative mortality, percentage of females, and mean number of laid eggs） of the 6 studied parameters （with the exception of development time）, the hybrid cohorts had better fitness results than the parental cohorts involved in each set of crosses. The increase in hybrid fitness found in our study could lead to an increase in the epidemiologic risks caused by transmission of Trypanosoma cruzi to humans.

Neonatal encephalopathy resulting from an asphyxial episode occurring perinatally is a major cause of death and of permanent neurological disabilities worldwide. Therapeutic hypothermia(TH) started within 6 hours of life and maintained for 72 hours is now well established as standard treatment for infants with moderate-to-severe hypoxicischemic encephalopathy(HIE).

In the last twenty years, new imaging techniques to assess atrial function and to predict the risk of recurrence of atrial fibrillation after treatment have been developed. The present review deals with the role of these techniques in the detection of structural and functional changes of the atrium and diagnosis of atrial remodeling, particularly atrial fibrosis. Echocardiography allows the detection of anatomical, functional changes and deformation of the atrial wall during the phases of the cardiac cycle. for this, adequate acquisition of atrial images is necessary using speckle tracking imaging and interpretation of the resulting strain and strain rate curves. This allows to predict new-onset atrial fibrillation and recurrences. Its main limitations are inter-observer variability, the existence of different software manufacturers, and the fact that the software used were originally developed for the evaluation of the ventricular function and are now applied to the atria. Cardiac magnetic resonance, using contrast enhancement with gadolinium, plays a key role in the visualization and quantification of atrial fibrosis. This is the established method for in vivo visualization of myocardial fibrotic tissue. The non-invasive evaluation of atrial fibrosis is associ- ated with the risk of recurrence of atrial fibrillation and with electro-anatomical endocardial mapping. We discuss the limitations of these techniques, derived from the difficulty of demonstrating the correlation between fibrosis imaging and histology, and poor intra- and inter- observer reproducibility. The sources of discordance are described, mainly due to image acquisition and processing, and the challenges ahead in an attempt to eliminate differences between operators.
