PMID: 16812559
J Exp Anal Behav. 1988 Sep;50(2):273-6. doi: 10.1901/jeab.1988.50-273.

This paper reports an experiment intended to demonstrate that the vertical jumping response can be learned using a signaled-avoidance technique. A photoelectric cell system was used to record the response. Twenty female rats, divided equally into two groups, were...

BACKGROUND: Tumor promoters enhance tumor yield in experimental animals without directly affecting the DNA of the cell. Promoters may play a role in the development of cancer, as humans are exposed to them in the environment. In work based...

Electrical conductivity of aqueous solutions of aluminum salts.

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

Phys Rev E Stat Nonlin Soft Matter Phys. 2005 Mar;71(3):031201. doi: 10.1103/PhysRevE.71.031201. Epub 2005 Mar 17.

We present experimental measurements of the specific electrical conductivity (sigma) in aqueous solutions of aluminum salts at different temperatures, covering all salt concentrations from saturation to infinite dilution. The salts employed were AlCl(3), AlBr(3), AlI(3), and Al(NO(3))(3), which present...

Using cost-effective targeting to enhance the efficiency of conservation investments in payments for ecosystem services.

Conservation biology : the journal of the Society for Conservation Biology

Conserv Biol. 2010 Dec;24(6):1469-78. doi: 10.1111/j.1523-1739.2010.01551.x.

Ecosystem services are being protected and restored worldwide through payments for ecosystem services in which participants are paid to alter their land-management approaches to benefit the environment. The efficiency of such investments depends on the design of the payment...

Observation of long-lived polariton states in semiconductor microcavities across the parametric threshold.

Physical review letters

Ballarini D, Sanvitto D, Amo A, Viña L, Wouters M, Carusotto I, Lemaitre A, Bloch J.
PMID: 19257528
Phys Rev Lett. 2009 Feb 06;102(5):056402. doi: 10.1103/PhysRevLett.102.056402. Epub 2009 Feb 02.

The excitation spectrum around the pump-only stationary state of a polariton optical parametric oscillator in semiconductor microcavities is investigated by time-resolved photoluminescence. The response to a weak pulsed perturbation in the vicinity of the idler mode is directly related...

Dynamics of the formation and decay of coherence in a polariton condensate.

Physical review letters

del Valle E, Sanvitto D, Amo A, Laussy FP, André R, Tejedor C, Viña L.
PMID: 19792816
Phys Rev Lett. 2009 Aug 28;103(9):096404. doi: 10.1103/PhysRevLett.103.096404. Epub 2009 Aug 26.

We study the dynamics of the formation and decay of a condensate of microcavity polaritons. We investigate the relationship among the number of particles, the emission linewidth, and its degree of linear polarization, which serves as the order parameter....

Front Mol Neurosci. 2011 Nov 16;4:45. doi: 10.3389/fnmol.2011.00045. eCollection 2011.

Increased GSK-3 activity is believed to contribute to the etiology of chronic disorders like Alzheimer's disease (AD), schizophrenia, diabetes, and some types of cancer, thus supporting therapeutic potential of GSK-3 inhibitors. Numerous mouse models with modified GSK-3 have been...
