The optimal weighting function for cosmic magnification measurements through the foreground galaxy-background galaxy (quasar) cross-correlation

, 2011
Cosmic magnification has been detected through the cross-correlation between foreground and background populations (galaxies or quasars). It has been shown that weighting each background object by its alpha - 1 can significantly improve the cosmic ...

Cell geometry and membrane protein crowding constrain Escherichia coli growth rate, overflow metabolism, respiration, and maintenance energy

FEBS Letters, EarlyView.
The physical dimensions and shape of bacterial cells define the surface area available to acquire nutrients and the volume available for synthesizing proteins and DNA. Here, we use computational systems biology to decode the importance of cell geometry as a major determinant of prokaryotic phenotype, including growth rate and metabolic efficiency. This

The Galaxy-Absorber Cross-Correlation Function

, 1997
We describe an analysis of the galaxy-absorber cross-correlation function as a function of velocity separation, impact parameter separation, and absorber Lyman alpha equivalent width on impact parameter scales that extend up to 1 Mpc.

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

FEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

Universal relation between the conditional auto-correlation function and the cross-correlation function of biphotons

Optics Express
We systematically studied the relation between the conditional auto-correlation function (CACF) and cross-correlation function (CCF) of biphotons or pairs of single photons. The biphotons were generated from a heated atomic vapor via the spontaneous four-wave mixing (SFWM) process.

From mice to humans—divergent strategies for intestinal homeostasis and regeneration

FEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

Uso de la función de correlación cruzada en la identificación de modelos ARMA

Revista Colombiana de Estadística, 2008
La función de correlación cruzada muestral (FCCM) ha sido empleada para estudiar la fortaleza y la dirección de la relación lineal entre dos procesos estocásticos conjuntamente estacionarios.

Accelerating a cross-correlation score function to search modifications using a single GPU

BMC Bioinformatics, 2018
Background A cross-correlation (XCorr) score function is one of the most popular score functions utilized to search peptide identifications in databases, and many computer programs, such as SEQUEST, Comet, and Tide, currently use this score function ...
