Fong DT, Lam MH, Lao ML, Chan CW, Yung PSh, Fung KY, Lui PP, Chan KM.
PMID: 18289375
J Orthop Surg Res. 2008 Feb 20;3:7. doi: 10.1186/1749-799X-3-7.

BACKGROUND: Excessive pronation (or eversion) at ankle joint in heel-toe running correlated with lower extremity overuse injuries. Orthotics and inserts are often prescribed to limit the pronation range to tackle the problem. Previous studies revealed that the effect is...

Island, pit, and groove formation in strained heteroepitaxy.

Phys Rev Lett. 2005 Aug 19;95(8):086102. doi: 10.1103/PhysRevLett.95.086102. Epub 2005 Aug 18.

We study the morphological evolution of strained heteroepitaxial films using a kinetic Monte Carlo method in three dimensions. The elastic part of the problem uses a Green's function method. Isolated islands are observed under deposition conditions for deposition rates...

Thermodynamic properties of molten Al-Mn, Al-Cu and Al-Fe-Cu alloys in a wide temperature range of 1123-1878 K and the whole range of concentrations have been studied using the integral effusion method and Knudsen mass spectrometry. Thermodynamic functions of melts...

Dynamic magnetic resonance imaging in assessing lung function in adolescent idiopathic scoliosis: a pilot study of comparison before and after posterior spinal fusion.

PMID: 18021435
J Orthop Surg Res. 2007 Nov 19;2:20. doi: 10.1186/1749-799X-2-20.

BACKGROUND: Restrictive impairment is the commonest reported pulmonary deficit in AIS, which improves following surgical operation. However, exact mechanism of how improvement is brought about is unknown. Dynamic fast breath-hold (BH)-MR imaging is a recent advance which provides direct...

Exact scaling in competitive growth models.

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

Braunstein LA, Lam CH.
PMID: 16196665
Phys Rev E Stat Nonlin Soft Matter Phys. 2005 Aug;72(2):026128. doi: 10.1103/PhysRevE.72.026128. Epub 2005 Aug 24.

A competitive growth model (CGM) describes the aggregation of a single type of particle under two different growth rules with occurrence probabilities p and 1-p . We explain the origin of the scaling behavior of the resulting surface roughness...

A preliminary investigation into the comparison of dissolution/digestion techniques for the chemical characterization of polyurethane foam.

PMID: 21075294
Sci Justice. 2010 Dec;50(4):177-81. doi: 10.1016/j.scijus.2010.03.002. Epub 2010 May 14.

Due to their widespread use in domestic and commercial premises, polyurethane foams, as either fragmented or bulk foam, are types of evidence commonly found at crime scenes. The traditional approach to determining the evidential value of polyurethane foam (PF)...

Development of Clinical Psychology and Mental Health Resources in Vietnam.

In this paper, we discuss development of the Vietnam National University graduate Clinical Psychology Program, which has the goal of training both Vietnamese researchers who will develop and evaluate culturally appropriate mental health treatments, as well as Vietnamese clinicians...

Development of diamidophosphite ligands and their application to the palladium-catalyzed vinyl-substituted trimethylenemethane asymmetric [3 + 2] cycloaddition.

Journal of the American Chemical Society

Trost BM, Lam TM.
PMID: 22716661
J Am Chem Soc. 2012 Jul 18;134(28):11319-21. doi: 10.1021/ja305717r. Epub 2012 Jul 03.

A palladium-catalyzed asymmetric [3 + 2] cycloaddition of a vinyl-substituted trimethylenemethane (TMM) donor with α,β-unsaturated acyl imidazoles is described. A newly designed bisdiamidophosphite ligand derived from (S,S)-trans-1,2-cyclohexanediamine and (2R,4R)-pentanediol has been instrumental for the development of this process. This...

Surface dynamics of noisy viscoelastic films by adiabatic approximation.

Langmuir : the ACS journal of surfaces and colloids

Lam CH, Tsui OK, Peng D.
PMID: 22694105
Langmuir. 2012 Jul 10;28(27):10217-22. doi: 10.1021/la301884j. Epub 2012 Jun 26.

Surface dynamics is sometimes used to determine the rheological properties of soft materials. In typical data analyses, surface capillary waves are included without incorporating thermal noise. A phenomenological expression for the time-dependent power spectral density has been proposed to...

Commercially available near-infrared (IR) imagers are fabricated by integrating expensive epitaxial grown III-V compound semiconductor sensors with Si-based readout integrated circuits (ROIC) by indium bump bonding which significantly increases the fabrication costs of these image sensors. Furthermore, these typical...
