Kondo effect of a Co atom on Cu(111) in contact with an Fe tip
, 2010 Single Co atoms, which exhibit a Kondo effect on Cu(111), are contacted with Cu and Fe tips in a low-temperature scanning tunneling microscope. With Fe tips, the Kondo effect persists with the Abrikosov-Suhl resonance significantly broadened. In contrast,

Inter-pocket pairing and gap symmetry in Fe-based superconductors with only electron pockets
, 2012 Pairing symmetry in recently discovered Fe-based metallic superconductors AFe$_2$Se$_2$ (A = K, Rb, Cs) with high transition temperature $T_c \sim 40$ K is currently a subject of intensive debates.

Dynamic hybrid position/force control of a two degree‐of‐freedom flexible manipulator
Journal of Robotic Systems, 1993 AbstractIn this article, a method is proposed whereby both contact force exerted by a flexible manipulator and position of end‐effector while in contact with a surface are controlled. We approximate elastic deformations by means of B‐spline functions and derive dynamic equations of joint angles, vibration of the flexible link, and constraint force.

Label-Free Potentiometry for Detecting DNA Hybridization Using Peptide Nucleic Acid and DNA Probes
Sensors, 2013 Peptide nucleic acid (PNA) has outstanding affinity over DNA for complementary nucleic acid sequences by forming a PNA-DNA heterodimer upon hybridization via Watson-Crick base-pairing.

Differential regulation of expression of the multiple ADP/ATP translocase genes in human cells [PDF]
, 1991 The expression of the genes encoding the three isoforms of the human ADP/ATP translocase (T1, T2, and T3) has been investigated in cultured cell systems under different experimental conditions, using isoform- specific probes.

PLoS BiologyOver the past 2 decades, biologists have come to appreciate that hybridization, or genetic exchange between distinct lineages, is remarkably common-not just in particular lineages but in taxonomic groups across the tree of life.

Caldasia, 1973 The hybridization of two species represents a method of more importance in obtaining the understanding of the relationships of these species. The crosses in vitro avoid the operation of the mechanisms that are aislated, as the characteristics of the ...

Introgression and rapid species turnover in sympatric damselflies
BMC Evolutionary Biology, 2011 Background Studying contemporary hybridization increases our understanding of introgression, adaptation and, ultimately, speciation. The sister species Ischnura elegans and I.
