A Frequency Domain Method for the Generation of Partially Coherent Normal Stationary Time Domain Signals

open access: yesShock and Vibration, 1993
A procedure for generating vectors of time domain signals that are partially coherent in a prescribed manner is described. The procedure starts with the spectral density matrix, [Gxx(f)] , that relates pairs of elements of the vector random process {X(t)}

Comparing the paths of Hedgehog release in artificial and natural settings

open access: yesFEBS Letters, EarlyView.
Hh morphogens require solubilization factors to overcome their tight association with the plasma membrane and signal to distant cells, but the precise functions of these factors are controversial. Here, we use published in vivo observations as the most relevant evidence to test their suggested functions and discuss contradictions and gaps between in ...

RECENT RESULTS ON THE DOMAIN OF THE SOME LIMITATION METHODS IN THE SEQUENCE SPACES f0 AND f

open access: yesJournal of New Theory, 2015
− In the present paper, we summarize the literature on the sequence spaces almost A−nulland almost A−convergent derived by using the domain of the certain A− limitation matrix.

Exploiting Trust and Usage Context for Cross-Domain Recommendation

open access: yesIEEE Access, 2016
Cross-domain recommender systems are usually able to suggest items, which are not in the same domain, where users provided ratings. For this reason, cross-domain recommendation has attracted more and more attention in recent years.

Mitochondrial translation and coordinated cytosolic translation in metabolic homeostasis and disease

open access: yesFEBS Letters, EarlyView.
Mitochondrial function depends on coordinated protein production from the nuclear and mitochondrial genomes. This review highlights how cytosolic and mitochondrial translation, mRNA localization, protein import, and respiratory complex assembly are integrated to maintain mitochondrial proteostasis and function.

Interaction between the respiratory syncytial virus G glycoprotein cytoplasmic domain and the matrix protein

open access: yes, 2005
Paramyxovirus assembly at the cell membrane requires the movement of viral components to budding sites and envelopment of nucleocapsids by cellular membranes containing viral glycoproteins, facilitated by interactions with the matrix protein.

Integrity of Narrow Epithelial Tubes in the C. elegans Excretory System Requires a Transient Luminal Matrix.

open access: yesPLoS Genetics, 2016
Most epithelial cells secrete a glycoprotein-rich apical extracellular matrix that can have diverse but still poorly understood roles in development and physiology.

Hijacking emergency granulopoiesis: Neutrophil ontogeny and reprogramming in cancer

open access: yesMolecular Oncology, EarlyView.
Neutrophils are highly plastic innate immune cells; their functions in cancer extend beyond the tumour microenvironment. This Review summarises current understanding of neutrophil maturation and heterogeneity and highlights tumour‐induced granulopoiesis as a systemic programme that expands immature, immunosuppressive neutrophils via tumour‐derived ...

Time domain localized-density-matrix method

open access: yes, 1998
A recently developed linear scaling localized-density-matrix method is modified, and the equation of motion for reduced single electron density matrix is solved for the absorption spectra of polyacetylene oligomers in the time-domain. The modified method
