Survey of intravitreal injection techniques among retina specialists in Israel.

Clinical ophthalmology (Auckland, N.Z.)

Segal O, Segal-Trivitz Y, Nemet AY, Geffen N, Nesher R, Mimouni M.
PMID: 27366050
Clin Ophthalmol. 2016 Jun 14;10:1111-6. doi: 10.2147/OPTH.S96452. eCollection 2016.

PURPOSE: The purpose of this study was to describe antivascular endothelial growth factor intravitreal injection techniques of retinal specialists in order to establish a cornerstone for future practice guidelines.METHODS: All members of the Israeli Retina Society were contacted by...

Berry phase in a nonisolated system.

Physical review letters

Whitney RS, Gefen Y.
PMID: 12785934
Phys Rev Lett. 2003 May 16;90(19):190402. doi: 10.1103/PhysRevLett.90.190402. Epub 2003 May 16.

We investigate the effect of the environment on a Berry phase measurement involving a spin-half. We model the spin + environment using a biased spin-boson Hamiltonian with a time-dependent magnetic field. We find that, contrary to naive expectations, the...

Weak values of electron spin in a double quantum dot.

Physical review letters

Romito A, Gefen Y, Blanter YM.
PMID: 18352406
Phys Rev Lett. 2008 Feb 08;100(5):056801. doi: 10.1103/PhysRevLett.100.056801. Epub 2008 Feb 05.

We propose a protocol for a controlled experiment to measure a weak value of the electron's spin in a solid state device. The weak value is obtained by a two step procedure--weak measurement followed by a strong one (postselection),...

Test-retest reliability of a new form of the auditory verbal learning test (AVLT).

Archives of clinical neuropsychology : the official journal of the National Academy of Neuropsychologists

Geffen GM, Butterworth P, Geffen LB.
PMID: 14589623
Arch Clin Neuropsychol. 1994 Jul;9(4):303-16.

The equivalence between the original form (Form 1) of the Auditory Verbal Learning Test (AVLT), and a new form (Form 4) was examined in 51 normal adult subjects (20-67 years) of average estimated intelligence who were assessed in two...

Geometric nature of the environment-induced Berry phase and geometric dephasing.

Physical review letters

Whitney RS, Makhlin Y, Shnirman A, Gefen Y.
PMID: 15783796
Phys Rev Lett. 2005 Feb 25;94(7):070407. doi: 10.1103/PhysRevLett.94.070407. Epub 2005 Feb 25.

We investigate the geometric phase or Berry phase acquired by a spin half which is both subject to a slowly varying magnetic field and weakly coupled to a dissipative environment (either quantum or classical). We study how this phase...

Changes in tyrosine hydroxylase and dopamine-beta-hydroxylase activities during degeneration of noradrenergic axons produced by antibodies to dopamine-beta-hydroxylase.

Neuroscience letters

Rush RA, Costa M, Furness JB, Geffen LB.
PMID: 19604888
Neurosci Lett. 1976 Nov;3(4):209-13. doi: 10.1016/0304-3940(76)90075-6.

Tyrosine hydroxylase (TH) and dopamine-beta-hydroxylase (DBH) activities were measured in various tissues of guinea-pigs 1-21 days after intravenous injection of antiserum against DBH. At 5 days a significant reduction in tissue levels of DBH was observed in all tissues...

Population switching and charge sensing in quantum dots: a case for a quantum phase transition.

Physical review letters

Goldstein M, Berkovits R, Gefen Y.
PMID: 20867195
Phys Rev Lett. 2010 Jun 04;104(22):226805. doi: 10.1103/PhysRevLett.104.226805. Epub 2010 Jun 03.

A broad and a narrow level of a quantum dot connected to two external leads may swap their respective occupancies as a function of an external gate voltage. By mapping this problem onto a multiflavored Coulomb gas we show...

Evaluation Plan for the Community Intervention Trial for Smoking Cessation (COMMIT).

International quarterly of community health education

Mattson ME, Cummings KM, Lynn WR, Giffen C, Corle D, Pechacek T.
PMID: 20840953
Int Q Community Health Educ. 1990 Jan 01;11(3):271-90. doi: 10.2190/PG9V-DRX1-EF2C-0NYH.

The National Cancer Institute is sponsoring the Community Intervention Trial for Smoking Cessation (COMMIT), a multi-center research project designed to test the value of a community-based effort to promote smoking cessation. The trial involves eleven matched pairs of communities...
