SARS-CoV-2 variants with concerning characteristics have emerged since the end of 2020. Surveillance was performed on a total 4,851 samples from capital city and 10 provinces Argentina, during 51 epidemiological weeks (EWs) that covered first wave ongoing second COVID-19 pandemic in country (EW 44/2020 to EW 41/2021). The surveillance strategy mainly based Sanger sequencing Spike coding region allows identification signature mutations associated variants. In addition, whole-genome sequences...
A novel fuzzy clustering technique for system identification based on the Takagi-Sugeno inference is proposed. In this paper, algorithm differs from others found in literature, manner that inference's antecedents and consequents are built. Gaussian sets with support cluster's ordinal set of a determined α-level unidimensional have as consequent an affine function, which recovers attributes collected data. Two simulations examples performed to compare new method: comparisons done well-known...

As part of a project to iniciate an Enviromental Engineering undergraduate student in the scientifict world advance researchers, purpose this study is model allometric relationship between weight and length species Plagioscion squamosissimus, Brazilian Cerrado region fish, commonly known as croaker. This among other species, reason for research “Peixe Vivo” (Fish Alive), launched by company, whose data source research. The motivation use fuzzy set theory comes from fact that, when objective...
A fuzzy identification of the dynamical system model is developed upon a data generated by software simulator hydrogen fuel cell. The presents black box model, just composed inputs and outputs, carry no additional information, showing strong nonlinear behavior. choice for based on features, malleability mathematical technique. This approach allows to accomplish objectives research, among which, validation method it used in other industrial problems. dynamic process performed using clustering...
A problem of a voltage division circuit is modeled in order to determine the values resistors, centered away that impedance resistance divider minimal. This equivalent maximizing admittance, associated resistance, which defined as quotient electric current and its voltage, measured Siemens. Three cases are analyzed for components linear programming: real numbers, fuzzy numbers type-1, set type-2. The first case considered validate other two cases. optimal solution programming type-1 obtained...
In the absence of antiviral alternatives, interventions under research for COVID-19 might be offered following guidelines from WHO monitored emergency use unregistered and experimental (MEURI). Ivermectin is among several drugs explored its role against SARS-CoV-2, with a well-known safety profile but conflicting data regarding clinical utility COVID-19. The aim this report to inform on results MEURI Program high-dose ivermectin in carried out by Ministry Health Province La Pampa, Argentina.

A Proportional, Integral and Derivative controller with Ziegler-Nichols tuning for the Van de Vusse reactor, whose circuit includes a fuzzy rule-based system of interval type-2, is compared classic control. In nonlinear process inverse response it assumed that perfectly agitated operating in isothermal isochoric conditions constant reaction. The mathematical model describes reaction given by ordinary differential equations which, Laplace transform method, associated second order transfer...

This paper deals with existence and regularity of positive solutions sublinear equations the form $-\Delta u + b(x)u =\lambda f(u)$ in $\Omega$ where either $\Omega\in R^N$ is a bounded smooth domain which case we consider Dirichlet problem or $\Omega =R^N$, look for solutions, $b$ not necessarily coercive continuous $f$ real function growth may have certain discontinuities. We explore method lower upper associated some subdifferential calculus.
