We use molecular dynamics simulations to study the structure, dynamics, and transport properties of nano-confined water between parallel graphite plates with separation distances (H) from 7 to 20 Å at different water densities with an emphasis on anisotropies generated by confinement. The behavior of the confined water phase is compared to non-confined bulk water under similar pressure and temp...

A weakly charged flexible polyelectrolyte chain in a neutral spherical cavity is analyzed by using self-consistent field theory within an explicit solvent model. Assuming the radial symmetry for the system, it is found that the confinement of the chain leads to creation of a charge density wave along with the development of a potential difference across the center of cavity and the surface. We ...

Arecibo mapping is reported of the neutral hydrogen distribution along selected directions out from the centers of two examples of small High Velocity Clouds (HVC). One HVC (W486) is selected from the class of Compact HVCs (CHVCs) thought by some researchers to be good candidates for having distances characteristic of the Local Group; the other (W491) is a bit more extended and possibly nearer....

When a tokamak plasma makes a transition into the good or the high confinement H mode, the edge density and pressure steepen and develop a very sharp pressure pedestal. Prediction of the height and width of this pressure profile has been actively pursued so as to provide a reliable extrapolation to future burning plasma devices. The double-Beltrami two-fluid equilibria of Mahajan and Yoshida fP...

The strength assessment of existing reinforced concrete structures is challenging when deterioration and detailing deficiencies are present. anchorage the internal steel reinforcement can be critical under particular confinement conditions external pressure, cover transverse reinforcement. interaction between different contributions their effects on bond were investigated with a novel experimen...

Introduction: In developing countries, 70% of new mothers do not receive postpartum care. In Malaysia there are a number of traditional postpartum practices commonly practiced by new mothers.Aim: To describe the beliefs and practices related to the traditional postpartum care among women who had given live births in a village in Penang, Malaysia. Methodology: A descriptive cross sectional study...

This paper reports on studies of the edge transport barrier and transition threshold of the High Confinement (H) mode of operation on the Alcator C-Mod tokamak [I. H. Hutchinson et al, Phys. Plasmas 1, 1511 (1994)], over a wide range of toroidal field (2.6-7.86 T) and plasma current (0.4-1.7 MA). The H-mode power threshold and edge temperature at the transition increase with field. Barrier widt...

Despite the importance of mitotic cell rounding in tissue development and cell proliferation, there remains a paucity of approaches to investigate the mechanical robustness of cell rounding. Here we introduce ion beam-sculpted microcantilevers that enable precise force-feedback-controlled confinement of single cells while characterizing their progression through mitosis. We identify three force...

Two types of instabilities were previously identified in inductive discharges having an expanding chamber when negative ions are present: i the source instability, occurring in the neighborhood of the capacitive-to-inductive E to H transition, and ii the downstream instability, which was shown to be the periodic formation and propagation of double layers. These unstable double layers were found...

We demonstrate a lab-on-a-chip that combines micro/nano-fabricated features with a Convex Lens-Induced Confinement (CLIC) device for the in situ analysis of single cells. A complete cycle of single cell analysis was achieved that includes: cell trapping, cell isolation, lysis, protein digestion, genomic DNA extraction and on-chip genomic DNA linearization. The ability to dynamically alter the f...
