One of the major developments of the second year of human life is the emergence of the ability to pretend. A child's knowledge of a real situation is apparently contradicted and distorted by pretense. If, as generally assumed, the child is just beginning to construct a system for internally representing such knowledge, why is this system of representation not undermined by its use in both compr...

With the development of nanotechnology that contains automatic control, precision machinery and precise measurement, etc., micro/nano manipulation has become a new research direction in recent years. This paper presents the design and analysis procedures of a new high precision XY decoupled compact parallel micromanipulator (DCPM) for micro scale positioning applications. The DCPM is made up of...

Voltage-activated currents in blue cones of the retinal slice of zebrafish were characterized using whole cell recording techniques. Depolarizing-elicited currents were recorded: an outward tetraethylammonium (TEA)-sensitive K+ current (IKx), an outward Ca(2+)-activated Cl- current (ICl(Ca)), from which we inferred an inward Ca2+ current (ICa) as well as a hyperpolarizing-elicited nonselective ...

It has been hypothesized that the (31)Phosphorus ((31)P) nuclear magnetic resonance spectrum from certain tumors may provide prognostic information. The goal of the present study was to identify prognostic metabolic markers by using proton-decoupled phosphorus magnetic resonance spectroscopic imaging ((31)P MRSI). Twenty patients with bone [osteogenic (OS) and Ewing's (ES) and/or primitive neur...

Abstract This work is devoted to the study of wormhole solutions in framework gravitational decoupling by means minimal geometric deformation scheme. As an example, analyze how this methodology works scenario, we have minimally deformed well-known Morris–Thorne model. The decoupler function f ( r ) and $$\theta $$ θ </mm...

The earliest types of two-dimensional NMR experiments that received widespread attention were the proton-flip and the gated-decoupler experiments (Z-8). Concep tually those early experiments are rather simple to understand, but the use of those experiments in practical cases often is complicated by data storage requirements and sensitivity considerations. Only in the case where the spectroscopi...

A new numerical methodology to examine fluid-structure interaction of a wing/pylon/store system has been developed. The aeroelastic equation of motion of the complete system is solved iteratively in the time domain using a two-entity numerical code comprised of ABAQUS/Standard and the Unsteady-Vortex-Lattice Method. Both codes communicate through an iterative handshake procedure during which di...

Traditional modulation methods for broadband proton decoupling (1-4) have now been superseded by modern pulse techniques (5) using sequences of composite 180” pulses (6). Initial progress was achieved with the MLEV decoupling sequences (7-9) and guided by coherent averaging theory (10). This approximate analysis showed that longer and more effective decoupling “supercycles” could be constructed...

Introduction Frontal lobe is involved in memory, emotion and higher mental functions. Most psychiatric disorders are believed to be related to dysfunction in the frontal lobe. Frontal lobe MR spectroscopy, however, has traditionally been quite challenging due to technical hurdles such as B0 field distortion and proton decoupling that may cause safety concerns due to poor perfusion of the eyes. ...
