The manipulation of the motion of neutral molecules with electric or magnetic fields has seen tremendous progress over the last decade. Recently, these techniques have been extended to the manipulation of large and complex molecules. In this article we introduce experimental approaches to the manipulation of large molecules, i.e., the deflection, focusing and deceleration using electric fields....

Electric-field measurements inside a negative-permeability-positive-permittivity metamaterial composed of arrays of split-ring resonators directly show that the theoretically predicted enhancement of evanescent waves in passive materials is physically realizable. To circumvent the extreme sensitivity of this phenomenon to the material parameters, we show how the basic phenomenon occurs under re...

As renewable energy increasingly integrates into the electric power system, electric load forecasting and renewable energy power generation forecasting become more important. In this project, ARIMA and NARX are applied to build load forecasting model focusing on improving statistical and computational efficiency without losing accuracy. ARIMA turns out to be better for short term forecasting wh...

Applications of Time-of-Flight Mass Spectrometer (TOF -MS) for RIMS are quite well known. Enhancement in mass resolution of RIMS signals is expected by replacing the TOF-MS with RTOF -MS. We have designed such a RTOF instrument as part of our RIMS set up. The mass spectrometer designed is based on optimization using an ion simulation software with improved resolution and sensitivity. The mass s...

Despite the many initiatives in recent years aimed at creating Language Engineering standards, it is often the case that di erent projects use di erent approaches and often de ne their own standards. Even within the same project it often happens that di erent tools will require di erent ways to represent their linguistic data. In a recently started EU project focusing on the integration of Info...

Thin Au films (~5 nm) are known to form island-like structures with small gaps between the islands, which produce intense electric field "hot spots" under visible illumination. In this work, we perform finite difference time domain (FDTD) simulations based on experimentally observed high resolution transmission electron microscope (HRTEM) images of these films in order to study the nature of th...

BACKGROUND During both cardiac maturation and myopathy, elevated levels of circulating catecholamines coincide with alterations in impulse propagation. An in vitro model of cultured cardiomyocytes was used to study the effects of adrenergic stimulation on the conduction characteristics of immature heart cells. METHODS AND RESULTS Neonatal rat cardiomyocytes were cultured on preparations desig...

A preparative scale free-flow isoelectric focusing (FF-IEF) device is developed and characterized with the aim of addressing needs of molecular biologists working with protein samples on the milligrams and milliliters scale. A triangular-shape separation channel facilitates the establishment of the pH gradient with a corresponding increase in separation efficiency and decrease in focusing time ...

This work demonstrates the feasibility of a hybrid radiofrequency (RF) applicator that supports magnetic resonance (MR) imaging and MR controlled targeted RF heating at ultrahigh magnetic fields (B0≥7.0T). For this purpose a virtual and an experimental configuration of an 8-channel transmit/receive (TX/RX) hybrid RF applicator was designed. For TX/RX bow tie antenna electric dipoles were employ...

Polarization independent liquid crystal (LC) microlens arrays based on controlling the spatial distribution of the Kerr constants of blue phase LC are simulated. Each sub-lens with a parabolic distribution of Kerr constants results in a parabolic phase profile when a homogeneous electric field is applied. We evaluate the phase distribution under different applied voltages, and the focusing prop...
