Evidence for a Finite-Temperature Insulator.

Scientific reports

Ovadia M, Kalok D, Tamir I, Mitra S, Sacépé B, Shahar D.
PMID: 26310437
Sci Rep. 2015 Aug 27;5:13503. doi: 10.1038/srep13503.

In superconductors the zero-resistance current-flow is protected from dissipation at finite temperatures (T) by virtue of the short-circuit condition maintained by the electrons that remain in the condensed state. The recently suggested finite-T insulator and the "superinsulating" phase are...

Under-flame Reaction of Sulfur-containing Amino Acids by a Hydrogen-Oxygen Flame.

Bioscience, biotechnology, and biochemistry

Nomoto S, Shimoyama A, Shiraishi S, Seno T, Sahara D.
PMID: 27392552
Biosci Biotechnol Biochem. 1998;62(4):643-9. doi: 10.1271/bbb.62.643.

Methionine was subjected to a flame-induced reaction in water or in an aqueous formic acid solution by using a hydrogen (50%)-oxygen (50%), hydrogen (87%)-oxygen (13%) and hydrogen diffusion flame. Besides the already-known stepwise oxidation by a hydroxyl radical, the...

The more the merrier? Increasing group size may be detrimental to decision-making performance in nominal groups.

PloS one

Amir O, Amir D, Shahar Y, Hart Y, Gal K.
PMID: 29485989
PLoS One. 2018 Feb 27;13(2):e0192213. doi: 10.1371/journal.pone.0192213. eCollection 2018.

Demonstrability-the extent to which group members can recognize a correct solution to a problem-has a significant effect on group performance. However, the interplay between group size, demonstrability and performance is not well understood. This paper addresses these gaps by...

Effect of environmental factors on intelligence quotient of children.

Industrial psychiatry journal

Makharia A, Nagarajan A, Mishra A, Peddisetty S, Chahal D, Singh Y.
PMID: 28659699
Ind Psychiatry J. 2016 Jul-Dec;25(2):189-194. doi: 10.4103/ipj.ipj_52_16.

INTRODUCTION: A child's intelligence quotient (IQ) is determined by both genetic and environmental factors that start from the prenatal period itself. There is a lack of data on the factors which influence IQ in Indian children; therefore, we conducted...

Thyroid dermopathy-a diagnostic clue of hidden hyperthyroidism.

Dermato-endocrinology

Dhali TK, Chahar M.
PMID: 26413185
Dermatoendocrinol. 2015 Jan 26;6(1):e981078. doi: 10.4161/19381980.2014.981078. eCollection 2014.

Thyroid dermopathy is an uncommon manifestation of autoimmune thyroid disease. About 0.5%-4.3% of patients with history of thyrotoxicosis and 15% of patients with severe Graves' ophthalmopathy have this cutaneous manifestation. However thyroid dermopathy is almost always associated with ophthalmopathy...

Nonequilibrium Second-Order Phase Transition in a Cooper-Pair Insulator.

Physical review letters

Doron A, Tamir I, Mitra S, Zeltzer G, Ovadia M, Shahar D.
PMID: 26894728
Phys Rev Lett. 2016 Feb 05;116(5):057001. doi: 10.1103/PhysRevLett.116.057001. Epub 2016 Feb 02.

In certain disordered superconductors, upon increasing the magnetic field, superconductivity terminates with a direct transition into an insulating phase. This phase is comprised of localized Cooper pairs and is termed a Cooper-pair insulator. The current-voltage characteristics measured in this...

Parallel magnetic field induced transition in transport in the dilute two-dimensional hole system in GaAs.

Physical review letters

Yoon J, Li CC, Shahar D, Tsui DC, Shayegan M.
PMID: 10990701
Phys Rev Lett. 2000 May 08;84(19):4421-4. doi: 10.1103/PhysRevLett.84.4421.

A magnetic field applied parallel to the two-dimensional hole system in the GaAs/AlGaAs heterostructure, which is metallic in the absence of an external magnetic field, can drive the system into insulating at a finite field through a well-defined transition....

Observation of a quantized hall resistivity in the presence of mesoscopic fluctuations.

Physical review letters

Peled E, Shahar D, Chen Y, Sivco DL, Cho AY.
PMID: 12857211
Phys Rev Lett. 2003 Jun 20;90(24):246802. doi: 10.1103/PhysRevLett.90.246802. Epub 2003 Jun 18.

We present an experimental study of mesoscopic, two-dimensional electronic systems at high magnetic fields. Our samples, prepared from a low-mobility InGaAs/InAlAs wafer, exhibit reproducible, sample specific, resistance fluctuations. Focusing on the lowest Landau level, we find that, while the...

Silicates as nonspecific adsorbents of bacteriophage: a model for purification of water from viruses.

Applied and environmental microbiology

Fass R, Straussman Y, Shahar A, Mizrahi A.
PMID: 16345491

Amorphous silicates having small particles with a large surface area were found to have high nonspecific adsorption capacity. Investigations with Escherichia coli T4 bacteriophage have shown adsorption capacity of up to 99.9% on different tested silicates. Optimal conditions for...
