Mesoscopic systems - small electric circuits working in quantum regime - offer us a unique experimental stage to explorer quantum transport in a tunable and precise way. The purpose of this Review is to show how they can contribute to statistical physics. We introduce the significance of fluctuation, or equivalently noise, as noise measurement enables us to address the fundamental aspects of a ...

Diurnal variation of upper tropospheric humidity and its relations to convective activities over tropical Africa E. S. Chung, B. J. Sohn, J. Schmetz, and M. Koenig School of Earth and Environmental Sciences, Seoul National University, Seoul, Korea European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT), Darmstadt, Germany Received: 20 October 2006 – Accepted: 19 Decem...

Huancayo is the only equatorial electrojet station where the daytime increase of horizontal geomagnetic ®eld (H) is associated with a simultaneous increase of eastward geomagnetic ®eld (Y). It is shown that during the counter electrojet period when DH is negative, DY also becomes negative. Thus, the diurnal variation of DY at equatorial latitudes is suggested to be a constituent part of the equ...

to determine the prognostic value of response to treatment in patients with focal segmental glomerulo-sclerosis. fsgs includes 10-15% of idiopathic nephrotic syndrome in children. bulk of evidence supports disease relationship with immune system. unfortunately, responses to immunosuppressive drugs are not desirable and progression to end-stage renal disease is common. we analyzed 62 out of 99 c...

objective(s): researchers have intended to reformulate drugs so that they may be more safely used in human body. polymer science and nanotechnology have great roles in this field. the aim of this paper is to introduce an efficient drug delivery vehicle which can perform both targeted and controlled antibiotic release using magnetic nanoparticles grafted ph-responsive polymer.  methods: fe3o4 na...

This Issue Brief examines the 1999 contribution behavior of 1.7 million 401(k) plan participants drawn from the EBRI/ICI Participant-Directed Retirement Plan Data Collection Project. The findings in this paper build on previous academic research examining the contribution activity of 401(k) participants, by using a large sample of participants in a wide range of plan sizes and by examining in d...

We report an original method that provides a new insight into the reaction mechanism by direct observation of bond breaking and formation. Variations of the diagonal elements of the Hessian along the IRC are shown to reflect the anharmonic properties of the system that are induced by electron density modifications upon the reaction. This information is presented in the form of the reaction spec...

We report multi-responsive and double-folding bilayer hydrogel sheet actuators, whose directional bending response is tuned by modulating the solvent quality and temperature and where locally crosslinked regions, induced by ionoprinting, enable the actuators to invert their bending axis. The sheets are made multi-responsive by combining two stimuli responsive gels that incur opposing and comple...

We study the propagation of quantum fields through an electromagnetically induced transparency (EIT) medium with initially two squeezed and one coherent states. Conditions to preserve and to establish nonseparation criteria for perturbed quantized fluctuation fields are demonstrated. The results in this work provide a guideline for using EIT media as quantum light devices.
