Evaluation of pre‐Northridge steel moment‐resisting frame joints

Build and Broaden 3.0 AND Program Evaluation

A Whittaker, A Gilani, V Bertero - The Structural Design of Tall …, 1998 - Wiley Online Library

The 1994 Northridge earthquake caused widespread and unexpected damage to steel moment‐resisting joints and connections. Shortly following the earthquake, the Federal Emergency Management Agency funded a series of full‐scale tests of steel moment‐resisting joints and connections to characterize the...

Spin Textures of Exciton-Polaritons in a Tunable Microcavity with Large TE-TM Splitting.

Physical review letters

Dufferwiel S, Li F, Cancellieri E, Giriunas L, Trichet AA, Whittaker DM, Walker PM, Fras F, Clarke E, Smith JM, Skolnick MS, Krizhanovskii DN.
PMID: 26705642
Phys Rev Lett. 2015 Dec 11;115(24):246401. doi: 10.1103/PhysRevLett.115.246401. Epub 2015 Dec 08.

We report an extended family of spin textures of zero-dimensional exciton-polaritons spatially confined in tunable open microcavity structures. The transverse-electric-transverse-magnetic (TE-TM) splitting, which is enhanced in the open cavity structures, leads to polariton eigenstates carrying quantized spin vortices. Depending...

Computational Analysis of the Mode of Action of Disopyramide and Quinidine on hERG-Linked Short QT Syndrome in Human Ventricles.

Frontiers in physiology

Whittaker DG, Ni H, Benson AP, Hancox JC, Zhang H.

Front Physiol. 2017 Oct 04;8:759. doi: 10.3389/fphys.2017.00759. eCollection 2017.

The short QT syndrome (SQTS) is a rare cardiac disorder associated with arrhythmias and sudden death. Gain-of-function mutations to potassium channels mediating the rapid delayed rectifier current,

Discrimination on all fronts.

Nursing standard (Royal College of Nursing (Great Britain) : 1987)

Whittaker AG.
PMID: 27238337
Nurs Stand. 1990 Apr 04;4(28):37. doi: 10.7748/ns.4.28.37.s43.

As a male, I really do get fed up with this constant sex discrimination talk, implying it is only the female who is discriminated against. In this country the two most blatant acts of sex discrimination are against the...

Angle-resonant stimulated polariton amplifier.

Physical review letters

Savvidis PG, Baumberg JJ, Stevenson RM, Skolnick MS, Whittaker DM, Roberts JS.
PMID: 11017564
Phys Rev Lett. 2000 Feb 14;84(7):1547-50. doi: 10.1103/PhysRevLett.84.1547.

We experimentally demonstrate resonant coupling between photons and excitons in microcavities which can efficiently generate enormous single-pass optical gains approaching 100. This new parametric phenomenon appears as a sharp angular resonance of the incoming pump beam, at which the...

Continuous wave observation of massive polariton redistribution by stimulated scattering in semiconductor microcavities.

Physical review letters

Stevenson RM, Astratov VN, Skolnick MS, Whittaker DM, Emam-Ismail M, Tartakovskii AI, Savvidis PG, Baumberg JJ, Roberts JS.
PMID: 11030980
Phys Rev Lett. 2000 Oct 23;85(17):3680-3. doi: 10.1103/PhysRevLett.85.3680.

A massive redistribution of the polariton occupancy to two specific wave vectors, zero and approximately 3.9x10(4) cm(-1), is observed under conditions of continuous wave excitation of a semiconductor microcavity. The "condensation" of the polaritons to the two specific states...

Excited state dynamics and rapid internal conversion in a stable dipole molecule.

Photochemical & photobiological sciences : Official journal of the European Photochemistry Association and the European Society for Photobiology

Reid GD, Whittaker DJ, Roth W, Whitaker BJ, Williamson MJ, Beddard GS.
PMID: 12803082
Photochem Photobiol Sci. 2003 May;2(5):585-90. doi: 10.1039/b301728a.

The excited singlet state of an azomethine ylide or 'stable dipole' exhibits an ultrafast radiationless relaxation after femtosecond laser excitation. These transients are observed before the excited state decays in an almost activationless manner, the barrier is 440 cm-1,...

Inhibited emission in photonic woodpile lattices.

Optics letters

Whittaker DM.
PMID: 18064181
Opt Lett. 2000 Jun 01;25(11):779-81. doi: 10.1364/ol.25.000779.

The emission and transmission properties of realistic photonic-band-structure woodpile lattices are investigated by use of a scattering-matrix treatment. Lattices with three to nine layers are studied, and the results are interpreted with band-structure calculations for an infinite lattice. Calculations...

Carbon: a new view of its high-temperature behavior.

Science (New York, N.Y.)

Whittaker AG.
PMID: 17743239
Science. 1978 May 19;200(4343):763-4. doi: 10.1126/science.200.4343.763.

An increasing body of research indicates that carbon can exist in a number of polymorphic "carbyne" forms. It is proposed that these forms occur because of a shift to triple bonding in the carbon system as temperature increases above...
