For each n∈N, we introduce the algebraic semantics for the minimum many-valued modal logic over the MV-chain with n elements. We prove that this quasivariety of algebras is generated by the complex algebras, obtaining ...

We have analyzed the DNA-binding properties of the complex formed by the Arabidopsis TALE homeodomain (HD) proteins STM and BLH3 in comparison with those of the individual proteins. In vitro DNA-binding assays indicated ...

Leishmaniasis is a parasitic disease caused by hemoflagellates of the genus Leishmania and is transmitted to humans by the bite of infected phlebotomine sandflies. Depending on the Leishmania species, the disease has dif...

La casa Samay Huasi (Universidad Nacional de La Plata, Argentina) conserva una colección de arte formada por más de 70 piezas entre pinturas, grabados y esculturas. En el origen de esa colección se encuentran las visi...

In this work we show that global topological properties of co-occurrent word networks constructed from texts, seem to be the fingerprint of meaningful sentences. We observe that many statistical properties of these netwo...

In a recent study we found that crania from South Amerindian populations on each side of the Andes differ significantly in terms of craniofacial shape. Western populations formed one morphological group, distributed cont...

Sideroxylon obtusifolium (Humb. ex Roem. & Schult.) T.D. Penn. is a tree species belonging to the Sapotaceae family, whose black berries can be consumed fresh or as jam. It is widely distributed in Mexico, Belize, Costa ...

We report the emergency development and application of a robust serologic test to evaluate acute and convalescent antibody responses to SARS-CoV-2 in Argentina. The assays, COVIDAR IgG and IgM, which were produced and pr...

La Bahía Samborombón se caracteriza por el dominio de agua subterránea salina, presentando como única fuente de agua potable las lentes de agua dulce acumuladas en los cordones de conchilla. Desde principios del sigl...

This paper attempts to design statistical models to forecast annual precipitation in the Neuquen and Limay river basins in the Comahue region of Argentina. These forecasts are especially useful as they are used to better...

Infection by Brucella species in pregnant animals and humans is associated with an increased risk of abortion, preterm birth, and transmission of the infection to the offspring. The pathogen has a marked tropism for the ...

A magnetic levitation control system is developed in this work. The non-linear system model is linearized around the operating point. Two control loops, an inner current loop and an outer position loop are designed using...

The immune system is an important modulator of learning, memory and neural plasticity. Interleukin 1β (IL-1β), a pro-inflammatory cytokine, significantly affects several cognitive processes. Previous studies by our gro...

We study the correlator of concentric circular Wilson loops for arbitrary radii, spatial and internal space separations. For real values of the parameters specifying the dual string configuration, a typical Gross-Ooguri ...

Ombrotrophic peat bogs from Tierra del Fuego are characteristically raised, dome-shaped, fed by precipitation, and nutrient-poor. Their landscape pattern consists of a Sphagnum magellanicum matrix encompassing pools with...

Background: Bone turnover markers are useful to evaluate bone loss and monitor anticatabolic treatments in a short period. The effectiveness of saliva to reflect changes in bone turnover markers during the early administ...

When males have high reproductive investment and female quality is variable, male assessment of sexual partners is expected. Allocosa alticeps (Mello-Leitão 1944) is a nocturnal wolf spider that shows a reversal in th...

Access to health services is a multidimensional and multistage phenomenon. Despite the extensive development of the theoretical framework of access to health care, until now, no indices have been developed to measure all...

En este trabajo proponemos reflexionar sobre la obra de Horacio González a partir de la figura del ejemplo. Primero, indagamos la figura desde los debates que suscitó su uso en el campo de la filosofía; luego postulam...

Studying demographic changes in past human populations is of great interest due to their role in processes of cultural change as well as the biological evolution of populations. Despite this, a general consensus about th...

This work studies the production of high-value compounds by the cross-metathesis of methyl oleate (MO) with ethylene, cinnamonitrile and cinnamaldehyde using the 2nd generation Hoveyda-Grubbs complex (HG) as catalyst, ei...

This paper examines the relationship between population growth and economic growth using panel data from 111 countries over the period from 1960 to 2019. In the first stage of the analysis, we divided the sample into thr...

Non-genotoxic carcinogens are substances that induce tumorigenesis by non-mutagenic mechanisms and long term rodent bioassays are required to identify them. Recent studies have shown that transcription profiling can be a...
