Statistical mechanics of nonrelativistic charged particles in a constant magnetic field.

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

Standen GB, Toms DJ.
PMID: 11970396
Phys Rev E Stat Phys Plasmas Fluids Relat Interdiscip Topics. 1999 Nov;60(5):5275-86. doi: 10.1103/physreve.60.5275.

The statistical mechanics of a system of nonrelativistic charged particles in a constant magnetic field is discussed. The spatial dimension D is arbitrary, with D>or=3 assumed. Calculations are presented from first principles using the effective action method. For D>or=5...

Sulfur ylides via decarboxylation of carboxymethylsulfonium betaines: a novel and mild protocol for the preparation of oxiranes.

Organic letters

Forbes DC, Standen MC, Lewis DL.
PMID: 12816429
Org Lett. 2003 Jun 26;5(13):2283-6. doi: 10.1021/ol034612a.

A novel protocol for the generation of sulfur ylides is described. The overall process involves thermal decarboxylation of a carboxymethylsulfonium betaine to give a sulfur ylide that, in the presence of an aldehyde, affords the corresponding terminal oxirane. Yields...

Spatial modelling of individual-level parasite counts using the negative binomial distribution.

Biostatistics (Oxford, England)

Alexander N, Moyeed R, Stander J.
PMID: 12933567
Biostatistics. 2000 Dec;1(4):453-63. doi: 10.1093/biostatistics/1.4.453.

We present a spatial model for the mean and correlation of highly dispersed count data, and apply it to individual-level counts of the nematode Wuchereria bancrofti, a parasite of humans which causes the disease lymphatic filariasis. Our model uses...

Preparing alpha,beta-unsaturated Fischer-type carbene complexes via an unforeseen route.

Dalton transactions (Cambridge, England : 2003)

Stander E, Cronje S, Raubenheimer HG.
PMID: 17213927
Dalton Trans. 2007 Jan 28;(4):424-9. doi: 10.1039/b615079a. Epub 2006 Dec 05.

Four 4-(NH-amino)-1-metalla-1,3-diene carbene complexes, two of which contain novel 4-membered heterometallacycles, formed regioselectively from the reaction of a mixture of [(CH(3))(2)(CH(3)S)S][BF(4)], the acetonitrilium electrophile, CH(3)CNCH(3)(+), and the deprotonated alkoxycarbene complexes, (CO)(5)M=C(OCH(3))CH(2)Li (M = Cr, W). The preferred Z-configurations of...

Collision photography: polarization imaging of atom-molecule collisions.

The Journal of chemical physics

Goldstein R, Figl C, Grosser J, Hoffmann O, Jungen M, Stalder J, Rebentrost F.
PMID: 15527340
J Chem Phys. 2004 Nov 08;121(18):8769-74. doi: 10.1063/1.1799592.

We report differential scattering experiments on the laser excitation of Na + M collision pairs with M = N(2), CO, C(2)H(2), and CO(2). The collision event is probed by the laser polarization revealing geometric and electronic properties of the...

S-Methylidene Agents: Preparation of Chiral Non-Racemic Heterocycles.

Tetrahedron

Forbes DC, Bettigeri SV, Patrawala SA, Pischek SC, Standen MC.
PMID: 20049065
Tetrahedron. 2009 Jan 03;65(1):70-76. doi: 10.1016/j.tet.2008.10.019.

Reaction of sulfur ylide with aldehyde, imine, and ketone functionality affords the desired three-membered heterocycle in excellent yield. The sulfur ylide is generated in situ upon decarboxylation of carboxymethylsulfonium betaine functionality. Of the seven carboxymethylsulfonium betaine derivatives surveyed, the...

A user-friendly clinical practice guideline summary for managing low back pain in South Africa.

The South African journal of physiotherapy

Stander J, Grimmer K, Brink Y.
PMID: 32161826
S Afr J Physiother. 2020 Feb 20;76(1):1366. doi: 10.4102/sajp.v76i1.1366. eCollection 2020.

BACKGROUND: Clinical practice guidelines (CPGs) provide conveniently packaged evidence-based recommendations to inform clinical decisions. However, intended end-users often do not know how to source, appraise, interpret or choose among CPGs. Moreover, it can be confusing when recommendations on the...

Virtual rehabilitation: What are the practical barriers for home-based research?.

Digital health

Threapleton K, Drummond A, Standen P.
PMID: 29942551
Digit Health. 2016 Apr 29;2:2055207616641302. doi: 10.1177/2055207616641302. eCollection 2016.

Virtual reality technologies are becoming increasingly accessible and affordable to deliver, and consequently the interest in applying virtual reality within rehabilitation is growing. This has resulted in the emergence of research exploring the utility of virtual reality and interactive...
