Entrainment of a driven oscillator as a dynamical phase transition.

Physical review. E, Statistical, nonlinear, and soft matter physics

Dickson A, Tabei SM, Dinner AR.
PMID: 22304067
Phys Rev E Stat Nonlin Soft Matter Phys. 2011 Dec;84(6):061134. doi: 10.1103/PhysRevE.84.061134. Epub 2011 Dec 20.

Large deviation theory has emerged as the natural language with which to study transitions between dynamical phases, such as the glass transition. Here we use this approach to show that the entrainment of an oscillator to an external driving...

"Piensa" twice: on the foreign language effect in decision making.

Cognition

Costa A, Foucart A, Arnon I, Aparici M, Apesteguia J.
PMID: 24334107
Cognition. 2014 Feb;130(2):236-54. doi: 10.1016/j.cognition.2013.11.010. Epub 2013 Dec 11.

In this article, we assess to what extent decision making is affected by the language in which a given problem is presented (native vs. foreign). In particular, we aim to ask whether the impact of various heuristic biases in...

PMID: 23377303
Neurosciences (Riyadh). 2004 Jan;9(1):46-8.

OBJECTIVE: The aim of this study was to screen a sample Palestinian population for sleep habits and various sleep disorders using a standard questionnaire.METHODS: The questionnaire was designed to assess sleep habits, the degree of daytime sleepiness using the...

Wide-field, surface-sensitive four-wave mixing microscopy of nanostructures.

Applied optics

Wang Y, Liu X, Halpern AR, Cho K, Corn RM, Potma EO.
PMID: 22695564
Appl Opt. 2012 Jun 01;51(16):3305-12. doi: 10.1364/AO.51.003305.

We describe a wide-field four-wave mixing (FWM) microscope with imaging characteristics optimized for examining nanostructures. The microscope employs surface-plasmon polariton (SPP) excitation in a gold film to achieve surface-sensitive imaging conditions. The SPP surface fields boost the FWM efficiency...

Duplicate publications: A sample of redundancy in the Journal of Urology.

Canadian Urological Association journal = Journal de l'Association des urologues du Canada

Hennessey KK, Williams AR, Afshar K, Macneily AE.
PMID: 22664627
Can Urol Assoc J. 2012 Jun;6(3):177-80. doi: 10.5489/cuaj.11265.

PURPOSE: : Redundant publications occur when authors publish a partial or complete duplicate of data from an existing manuscript. The push for academic advancement in medicine may result in redundant publications that erode the quality of literature. We sampled...

(E)-4-Hy-droxy-N'-(4-hy-droxy-3-meth-oxy-benzyl-idene)benzohydrazide.

Acta crystallographica. Section E, Structure reports online

Shalash M, Salhin A, Adnan R, Yeap CS, Fun HK.
PMID: 21589430
Acta Crystallogr Sect E Struct Rep Online. 2010 Nov 13;66:o3126-7. doi: 10.1107/S1600536810045162.

In the title compound, C(15)H(14)N(2)O(4), the N=C double bond has an E configuration. The two benzene rings make a dihedral angle of 28.59 (6)°. In the crystal, mol-ecules are linked into a three-dimensional network by inter-molecular N-H⋯O, O-H⋯O and...

Hollow ARROW Waveguides on Self-Aligned Pedestals for Improved Geometry and Transmission.

IEEE photonics technology letters : a publication of the IEEE Laser and Electro-optics Society

Lunt EJ, Wu B, Keeley JM, Measor P, Schmidt H, Hawkins AR.
PMID: 21423839
IEEE Photonics Technol Lett. 2010 Jul 12;22(15):1147-1149. doi: 10.1109/LPT.2010.2051145.

Micrometer-sized hollow antiresonant reflecting optical waveguides on silicon substrates have been previously demonstrated with liquid and gas-filled cores. Previous designs have nonideal geometries, with nonuniform lateral layers around the hollow core, resulting in higher loss than could potentially be...

A comparison of the sensory and rheological properties of molecular and particulate forms of xanthan gum.

Food hydrocolloids

Abson R, Gaddipati SR, Hort J, Mitchell JR, Wolf B, Hill SE.
PMID: 24591753
Food Hydrocoll. 2014 Mar;35(100):85-90. doi: 10.1016/j.foodhyd.2013.04.018.

A particulate form of xanthan gum was prepared by extrusion cooking. The temperature dependence of the viscosity of this form shows similarities to starch with an increase in viscosity to a maximum with increasing temperature as a result of...

The role of cuprous oxide seeds in the one-pot and seeded syntheses of copper nanowires.

Small (Weinheim an der Bergstrasse, Germany)

Ye S, Rathmell AR, Ha YC, Wilson AR, Wiley BJ.
PMID: 24616369
Small. 2014 May 14;10(9):1771-8. doi: 10.1002/smll.201303005. Epub 2014 Feb 25.

This paper demonstrates that Cu2O nanoparticles form in the early stages of a solution-phase synthesis of copper nanowires, and aggregate to form the seeds from which copper nanowires grow. Removal of ethylenediamine from the synthesis leads to the rapid...

Reversible sliding in networks of nanowires.

Nano letters

Wu J, Zang J, Rathmell AR, Zhao X, Wiley BJ.
PMID: 23634844
Nano Lett. 2013 Jun 12;13(6):2381-6. doi: 10.1021/nl4000739. Epub 2013 May 08.

This work demonstrates that metal nanowires in a percolating network can reversibly slide across one another. Reversible sliding allows networks of metal nanowires to maintain electrical contact while being stretched to strains greater than the fracture strain for individual...

Incorporating friction and collective shear moves into a lattice gas.

Physical review. E, Statistical, nonlinear, and soft matter physics

Dickson A, Nasto A, Dinner AR.
PMID: 20866189
Phys Rev E Stat Nonlin Soft Matter Phys. 2010 May;81(5):051111. doi: 10.1103/PhysRevE.81.051111. Epub 2010 May 11.

Here we examine a lattice-gas model that has been extended to include collective shear moves and friction interactions between particles. A shearlike field is applied by periodically translating entire subsections of the lattice with respect to one another, as...
