Galaxy star formation in different environments
(2009)
We use a semi-analytic model of galaxy formation to study signatures of large-scale modulations in the star formation (SF) activity in galaxies. In order to do this we carefully define local and global estimators of the ...
Strong responsiveness to noise interference in an anuran from the southern temperate forest
(2014)
Animals adopt different strategies to communicate by means of sound in noisy environments. Some animals increase, while others decrease, their vocal activity in the presence of interference. Anuran amphibians from diverse ...
Ample active acoustic space of a frog from the South American temperate forest
(2014)
The efficiency of acoustic communication depends on the power generated by the sound source, the attributes of the environment across which signals propagate, the environmental noise and the sensitivity of the intended ...
Human Respiratory Syncytial Virus: Infection and Pathology
(2016)
The human respiratory syncytial virus (hRSV) is by far the major cause of acute lower respiratory tract infections (ALRTIs) worldwide in infants and children younger than 2 years. The overwhelming number of hospitalizations ...
Intranasal cotinine improves memory and reduces depressive-like behavior, and GFAP+ cells loss induced by restraint stress in mice.
(2017)
Posttraumatic stress disorder (PTSD), chronic psychological stress, and major depressive disorder have been found to be associated with a significant decrease in glial fibrillary acidic protein (GFAP) immunoreactivity in ...
Vocal responsiveness to interfering sounds by a frog from the southern temperate forest, Batrachyla leptopus
(2015)
Interfering sounds from biotic and abiotic origins are likely to shape the responsiveness of sound communicating animals. Among these sources of interference, interactions among acoustically active species have been studied ...
Lack of phonotactic preferences of female frogs and its consequences for signal evolution
(2015)
Sexual selection is one of the main evolutionary forces that drive signal evolution. In previous studies, we have found out that males of Pleurodema thaul, a frog with an extensive latitudinal distribution in Chile, emits ...
Proinflammatory Cytokines in the Nucleus of the Solitary Tract of Hypertensive Rats Exposed to Chronic Intermittent Hypoxia
(2018)
Obstructive sleep apnea (OSA) is characterized by chronic intermittent hypoxia (CIH), which is considered the main factor for developing hypertension. Sympathetic overflow, oxidative stress and inflammation have been ...
Generalized Open Mapping Theorem for X-normed spaces
(2019)
The theory of X-normed spaces over non-Archimedean valued fields with valuations of higher rank was introduced by H. Ochsenius and W. H. Schikhof in [1] and further developed in [2–4, 6, 7] and [5]. In order to obtain ...
Identification of Post-Combustion Sub-Process Using Artificial Neural Networks
(BIOMEDICAL (Journal of Scientific & Technical Research), 2019-09-30)
In the muti-hearth furnace, there is a problem related to the automatic operation
of the loops of temperature regulation in hearths four and six, since the same flow of
air diverged into two branches. In this work, the ...
