Optimal switching between geocentric and egocentric strategies in navigation.

Royal Society open science

Peleg O, Mahadevan L.
PMID: 27493769
R Soc Open Sci. 2016 Jul 27;3(7):160128. doi: 10.1098/rsos.160128. eCollection 2016 Jul.

Animals use a combination of egocentric navigation driven by the internal integration of environmental cues, interspersed with geocentric course correction and reorientation. These processes are accompanied by uncertainty in sensory acquisition of information, planning and execution. Inspired by observations...

EMERGENCY BRAKING IN ADULTS VERSUS NOVICE TEEN DRIVERS: RESPONSE TO SIMULATED SUDDEN DRIVING EVENTS.

Transportation research record

Loeb HS, Kandadai V, McDonald CC, Winston FK.
PMID: 26709330
Transp Res Rec. 2015;2516:8-14. doi: 10.3141/2516-02.

Motor vehicle crashes remain the leading cause of death in teens in the United States. Newly licensed drivers are the group most at risk for crashes. Their driving skills are very new, still very often untested, so that their...

Women's views on human papillomavirus self-sampling: focus groups to assess acceptability, invitation letters and a test kit in the Australian setting.

Sultana F, Mullins R, Murphy M, English DR, Simpson JA, Drennan KT, Heley S, Wrede CD, Brotherton JM, Saville M, Gertig DM.
PMID: 26028338
Sex Health. 2015 Aug;12(4):279-86. doi: 10.1071/SH14236.

UNLABELLED: Background The study evaluated acceptability, invitation letters and the test kit for a trial of human papillomavirus (HPV) self-sampling among never- and under-screened women in Australia.METHODS: Victorian women, 30-69 years, who had never had a Pap test or...

Light-driven biocatalytic reduction of α,β-unsaturated compounds by ene reductases employing transition metal complexes as photosensitizers.

Catalysis science & technology

Peers MK, Toogood HS, Heyes DJ, Mansell D, Coe BJ, Scrutton NS.
PMID: 27019691
Catal Sci Technol. 2016 Jan 07;6(1):169-177. doi: 10.1039/c5cy01642h. Epub 2015 Oct 26.

Efficient and cost effective nicotinamide cofactor regeneration is essential for industrial-scale bio-hydrogenations employing flavin-containing biocatalysts such as the Old Yellow Enzymes. A direct flavin regeneration system using visible light to initiate a photoredox cycle and drive biocatalysis is described,...

Simulating shelf life determination by two simultaneous criteria.

Food research international (Ottawa, Ont.)

Peleg M, Normand MD.
PMID: 28433307
Food Res Int. 2015 Dec;78:388-395. doi: 10.1016/j.foodres.2015.09.003. Epub 2015 Sep 11.

The shelf life of food and pharmaceutical products is frequently determined by a marker's concentration or quality index falling below or surpassing an assigned threshold level. Naturally, different chosen markers would indicate different shelf life for the same storage...

Revealing the Formation of Copper Nanoparticles from a Homogeneous Solid Precursor by Electron Microscopy.

Journal of the American Chemical Society

van den Berg R, Elkjaer CF, Gommes CJ, Chorkendorff I, Sehested J, de Jongh PE, de Jong KP, Helveg S.
PMID: 26891132
J Am Chem Soc. 2016 Mar 16;138(10):3433-42. doi: 10.1021/jacs.5b12800. Epub 2016 Mar 04.

The understanding of processes leading to the formation of nanometer-sized particles is important for tailoring of their size, shape and location. The growth mechanisms and kinetics of nanoparticles from solid precursors are, however, often poorly described. Here we employ...

Impact of Decentralized Care and the Xpert MTB/RIF Test on Rifampicin-Resistant Tuberculosis Treatment Initiation in Khayelitsha, South Africa.

Open forum infectious diseases

Cox HS, Daniels JF, Muller O, Nicol MP, Cox V, van Cutsem G, Moyo S, De Azevedo V, Hughes J.
PMID: 26034764
Open Forum Infect Dis. 2015 Feb 26;2(1):ofv014. doi: 10.1093/ofid/ofv014. eCollection 2015 Jan.

Background.  Globally, case detection and treatment access are poor for rifampicin-resistant tuberculosis (RR-TB). The Xpert MTB/RIF test has the potential to increase detection and reduce time to treatment (TTT). However, these benefits are dependent on health system capacity to...

Nucleation and growth of Pt nanoparticles on reduced and oxidized rutile TiO₂ (110).

The Journal of chemical physics

Rieboldt F, Vilhelmsen LB, Koust S, Lauritsen JV, Helveg S, Lammich L, Besenbacher F, Hammer B, Wendt S.
PMID: 25481156
J Chem Phys. 2014 Dec 07;141(21):214702. doi: 10.1063/1.4902249.

The nucleation and growth of Pt nanoparticles (NP's) on rutile TiO2 (110) surfaces with O on-top atoms (oxidized TiO2), surface O vacancies, and H adatoms, respectively (reduced TiO2), was studied by means of scanning tunneling microscopy (STM) experiments and...

Dynamics of fractal dimension during phase ordering of a geometrical multifractal.

Physical review. E, Statistical physics, plasmas, fluids, and related interdisciplinary topics

Peleg A, Meerson B.
PMID: 11088637
Phys Rev E Stat Phys Plasmas Fluids Relat Interdiscip Topics. 2000 Aug;62(2):1764-8. doi: 10.1103/physreve.62.1764.

A simple multifractal coarsening model is suggested that can explain the observed dynamical behavior of the fractal dimension in a wide range of coarsening fractal systems. It is assumed that the minority phase (an ensemble of droplets) at t=0...

Normal scaling in globally conserved interface-controlled coarsening of fractal clusters.

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

Peleg A, Conti M, Meerson B.
PMID: 11580414
Phys Rev E Stat Nonlin Soft Matter Phys. 2001 Sep;64(3):036127. doi: 10.1103/PhysRevE.64.036127. Epub 2001 Aug 30.

We find that globally conserved interface-controlled coarsening of diffusion-limited aggregates exhibits dynamic scale invariance (DSI) and normal scaling. This is demonstrated by a numerical solution of the Ginzburg-Landau equation with a global conservation law. The general sharp-interface limit of...
