Theory of collective firing induced by noise or diversity in excitable media

diversity

Colet P, Scire A, Tessone CJ, Toral R.
GSID: 9_WJZlNYnIUJ
CJ Tessone, A Scire, R Toral, P Colet - Physical Review E, 2007 - APS

Large variety of physical, chemical, and biological systems show excitable behavior, characterized by a nonlinear response under external perturbations: only perturbations …

Effects of dynamic-demand-control appliances on the power grid frequency.

Physical review. E

Tchuisseu EBT, Gomila D, Brunner D, Colet P.
PMID: 28950641
Phys Rev E. 2017 Aug;96(2):022302. doi: 10.1103/PhysRevE.96.022302. Epub 2017 Aug 02.

Power grid frequency control is a demanding task requiring expensive idle power plants to adapt the supply to the fluctuating demand. An alternative approach is controlling the demand side in such a way that certain appliances modify their operation...

A Score Matrix for Thurstone's Box Problem.

Multivariate behavioral research

Kaiser HF, Horst P.
PMID: 26812418
Multivariate Behav Res. 1975 Jan 01;10(1):17-26. doi: 10.1207/s15327906mbr1001_2.

Since the score matrix for Thurstone's classic 20-variable box problem contains no measurement error and also genera1,es a singular correlation matrix, a new score matrix for this problem, both containing measurement error and having enough entities to yield a...

Trends in Two- and Three-Body Effects in Multiscale Clusters of Ionic Liquids.

The journal of physical chemistry. B

Halat P, Seeger ZL, Barrera Acevedo S, Izgorodina EI.
PMID: 27991797
J Phys Chem B. 2017 Jan 26;121(3):577-588. doi: 10.1021/acs.jpcb.6b10101. Epub 2017 Jan 11.

Applications of higher correlated levels of ab initio theory to condensed systems require a significant amount of computational resources. The recent development of the fragment molecular orbital (FMO) approach alleviates this issue by splitting the system into individual fragments...

L-type amino acid transport and cancer: targeting the mTORC1 pathway to inhibit neoplasia.

American journal of cancer research

Wang Q, Holst J.
PMID: 26101697
Am J Cancer Res. 2015 Mar 15;5(4):1281-94. eCollection 2015.

The L-type amino acid transporter (LAT) family are Na(+)-independent transporters, which deliver neutral amino acids into cells. The four LATs, LAT1 (SLC7A5), LAT2 (SLC7A8), LAT3 (SLC43A1) and LAT4 (SLC43A2), are responsible for the majority of cellular leucine uptake. They...

Dynamical properties induced by state-dependent delays in photonic systems.

Nature communications

Martínez-Llinàs J, Porte X, Soriano MC, Colet P, Fischer I.
PMID: 26081000
Nat Commun. 2015 Jun 17;6:7425. doi: 10.1038/ncomms8425.

In many dynamical systems and complex networks time delays appear naturally in feedback loops or coupling connections of individual elements. Moreover, in a whole class of systems, these delay times can depend on the state of the system. Nevertheless,...

Two dimensional imaging of the virtual source of a supersonic beam: helium at 125 K.

The journal of physical chemistry. A

Eder SD, Bracco G, Kaltenbacher T, Holst B.
PMID: 24328311
J Phys Chem A. 2014 Jan 09;118(1):4-12. doi: 10.1021/jp4082855. Epub 2013 Dec 20.

Here we present the first two-dimensional images of the virtual source of a supersonic helium expansion. The images were obtained using a free-standing Fresnel zone plate with an outermost zone width of 50 nm as imaging lens and a...

Acetyl Substitution of the O-Specific Caryan from the Lipopolysaccharide of Pseudomonas (Burkholderia) caryophylli Leads to a Block Pattern.

Angewandte Chemie (International ed. in English)

Molinaro A, De Castro C, Petersen BO, Duus JØ, Parrilli M, Holst O.
PMID: 10649359
Angew Chem Int Ed Engl. 2000 Jan;39(1):156-160.

An exceptionally large repeating unit has been proposed for one of the two O-specific polysaccharides of the lipopolysaccharide from Pseudomonas (Burkholderia) caryophylli, which is a homopolymer of the sugar caryose. This proposal is based on the unusual acetylation pattern...

Stable droplets and growth laws close to the modulational instability of a domain wall.

Physical review letters

Gomila D, Colet P, Oppo GL, San Miguel M.
PMID: 11690411
Phys Rev Lett. 2001 Nov 05;87(19):194101. doi: 10.1103/PhysRevLett.87.194101. Epub 2001 Oct 17.

We consider the curvature driven dynamics of a domain wall separating two equivalent states in systems displaying a modulational instability of a flat front. An amplitude equation for the dynamics of the curvature close to the bifurcation point from...

Molybdenum complexes with linked cycloheptatrienyl-phenolate ligands.

Inorganic chemistry

Tamm M, Bannenberg T, Dressel B, Fröhlich R, Holst C.
PMID: 11782143
Inorg Chem. 2002 Jan 14;41(1):47-59. doi: 10.1021/ic010902g.

The tropylium salt (2-hydroxy-3,5-dimethylphenyl)cycloheptatrienylium tetrafluoroborate (3) has been synthesized in three steps from THP-protected 2,4-dimethylphenol and tropylium tetrafluoroborate, (C(7)H(7))BF(4). In CH(2)Cl(2) solution, the unexpected formation of tricyclic 2,4-dimethylbenzo[b]cyclohepta[d]furanylium tetrafluoroborate (5) has been observed, which must have formed from 3...
