Theoretical models of planetary system formation: mass vs semi-major axis [PDF]

open access: yes, 2013
Planet formation models have been developed during the last years in order to try to reproduce the observations of both the solar system, and the extrasolar planets. Some of these models have partially succeeded, focussing however on massive planets, and

Mapping the evolution of mitochondrial complex I through structural variation

open access: yesFEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Theoretical models that can be applied to address therapeutic adherence.

open access: yesMexican Journal of Medical Research ICSA
Therapeutic adherence is defined by the WHO as "the degree to which patients' behavior, in relation to taking medication, following a diet or making lifestyle changes, corresponds to the recommendations agreed with the healthcare professional." Good ...

Theoretical Models of the Galactic Bulge

open access: yes, 2015
Near infrared images from the COBE satellite presented the first clear evidence that our Milky Way galaxy contains a boxy shaped bulge. Recent years have witnessed a gradual paradigm shift in the formation and evolution of the Galactic bulge. Bulges were

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

open access: yesFEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

Contemporaneous Emotion Regulation Theoretical Models: A Systematic Review

open access: yesInteracciones, 2022
Background: Emotions and their regulation are a phenomenon present in everyday life. Despite its relevance and growing interest, a consensual and univocal definition has not yet been reached.

Theoretical Models of Stellar Activity Cycles

open access: yes, 2012
We discuss possible mechanisms underlying the observed features of stellar activity cycles, such as multiple periodicities in very active stars, non-cyclic activity observed in moderately active stars, and spatial distribution of stellar magnetic regions.

Time after time – circadian clocks through the lens of oscillator theory

open access: yesFEBS Letters, EarlyView.
Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.
