Neutrinos in Non-linear Structure Formation - a Simple SPH Approach

, 2011
We present a novel method for implementing massive neutrinos in N-body simulations. Instead of sampling the neutrino velocity distribution by individual point particles we take neutrino free-streaming into account by treating it as an effective redshift ...

Mapping the evolution of mitochondrial complex I through structural variation

FEBS 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)

Comparing the linear structure features of normal breast and architectural distortion tissue based on Linear Structure Identification (LSI)

Journal of Associated Medical Sciences, 2011
Architectural distortion (AD) indicates the occurrence of early breast cancer. In mammographic image, the line correspond to the linear structure of normal breast tissue differ from the distorted tissue.

A structure filter for the Eukaryotic Linear Motif Resource

BMC Bioinformatics, 2009
Background Many proteins are highly modular, being assembled from globular domains and segments of natively disordered polypeptides. Linear motifs, short sequence modules functioning independently of protein tertiary structure, are most abundant in ...

Structured Noncommutative Multidimensional Linear Systems [PDF]

SIAM Journal on Control and Optimization, 2005
We introduce a class of multidimensional linear systems with evolution along a free semigroup. The transfer function for such a system is a formal power series in noncommuting indeterminates. Standard system-theoretic properties (the operations of cascade/parallel connection and inversion, controllability, observability, Kalman decomposition, state ...

Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

FEBS Letters, EarlyView.
Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

Reciprocal control of viral infection and phosphoinositide dynamics

FEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

Two open problems about the liner structure of rotation symmetric Boolean functions

Tongxin xuebao, 2013
One open problem that the balanced rotation symmetric Boolean functions with degree n− 1 on even number of variables have no non-zero linear structure was proved.

Algebraic structure count of linear phenylenes and their congeners [PDF]

Journal of the Serbian Chemical Society, 2003
The algebraic structure count of the linear phenylene with h six-membered rings is known to be equal to h + 1. We show that the same expression applies if each four-membered ring in the phenylene is replaced by a linear array consisting of k four ...

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

FEBS 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
