(2007)The cytoskeleton and cytoskeletal motors play a fundamental role in neurotransmitter receptor trafficking, but proteins that link GABAB receptors (GABABRs) to the cytoskeleton have not been described. We recently identified ...
-
(Elsevier, 2017)Shape memory alloys, like B2–CuZr, are a class of materials that have the ability to recover their original shape when subjected to specific thermomechanical conditions. In this work, we carry out molecular dynamics ...
-
(Springer, 2013)Masking, a type of camouflage, has been argued to function as an antipredator mechanism helping to avoid detection or recognition by a prey or predator. However, research focused on the effects of masking on life history ...
-
(American Chemical Society, 1981-12-08)The electron impact-induced fragmentation of aristolochic acids and some synthetic model compounds has been investigated using high resolution mass spectrometry. It was found that the only primary cleavage given by ...
-
(1998)Objective: To assess the relative influence of maternal body composition at late gestation on birth weight. Methods: Maternal body composition was estimated in 224 women near term using a deuterium dilution technique. Using ...
-
(2007)What are the consequences of the natural variation in maternal body mass on offspring energetic performance? How are performance traits related to thermal physiology and energetics phenotypically integrated on offspring? ...
-
(Wiley, 2022)In vertebrates, thyroid hormones (THs) play an important role in the regulation of growth, development, metabolism, photoperiodic responses and migration. Maternally transferred THs are important for normal early phase ...
-
(BIOMED CENTRAL LTD, 2010-11-03)Background: Iron is essential for the maintenance of basic cellular processes. In the regulation of its cellular levels, ferritin acts as the main intracellular iron storage protein. In this work we present a mathematical ...
-
(ICME, México, 2008)The role of metaphors and the switch in cognitive modes in relation to visualization in learning and teaching mathematics is discussed, based on examples and case studies with students and teachers. We present some preliminary ...
-
(Wiley, 2017)We characterize the L-p-maximal regularity of an abstract fractional differential equation with delay on the Lebesgue spaces. The method is based on the theory of operator-valued Fourier multipliers and weighted Sobolev ...
-
(Hindawi Publishing Corporation, 2010)We study abstract equations of the form λu t u t c2Au t c2μAu t f t , 0 < λ < μ which is motivated by the study of vibrations of flexible structures possessing internal material damping. We introduce the ...
-
(Springer-Verlag, 2014)We study how the opinions of a group of individuals determine their spatial distribution and connectivity, through an agent-based model. The interaction between agents is described by a Hamiltonian in which agents are ...
-
(Universidad de Chile. Escuela de Salud Pública, 2020)Introducción: Las desigualdades socioeconómicas y territoriales se relacionan con la salud de la población santiaguina; sin embargo, los mecanismos causales que generan las inequidades en salud no están del todo claros. ...

(2012)This article describes the basic prey requirements of Paraphysa sp., a small mygalomorph spider from the central Andes. Paraphysa sp. can be maintained in captivity using mealworms (Tenebrio molitor) as its primary food ...
-
(WILEY-V C H VERLAG GMBH, 2007-02-11)Glycogen synthase catalyzes the incorporation of UDP-glucose into glycogen. The activity of the enzyme is usually measured either by a spectrophotometric method or by a radioassay. The first one is not suitable because ...
-
(2010)The volume of saliva in the mouth of sensory panelists was measured by a dilution assay using a freshly prepared beetroot extract as probe solution. An aliquot of the extract absorbing linearly at 531-nm (probe) was placed ...
-
(Elsevier, 2015)The experimental production cross section for the reaction natZn(p,x)67Ga has been measured in the energy range from 1.678 to 2.444 MeV. The methodology used in this work is based on characteristic X-ray emitted after ...
-
Measurements of Tropospheric Ice Clouds with a Ground-based CMB Polarization Experiment, POLARBEAR (Institute of Physics, 2019)The polarization of the atmosphere has been a long-standing concern for ground-based experiments targeting cosmic microwave background (CMB) polarization. Ice crystals in upper tropospheric clouds scatter thermal radiation ...
-
(Copernicus Gesellschaft MBH, 2020)Four geographical zones are defined along the trench that is formed due to the subduction of the Nazca plate underneath the South American plate; they are denoted A, B, C and D from north to south; zones A, B and D had a ...
