Due to the limitations of fluorescence imaging techniques, the study of intracellular cargo is typically restricted to two-dimensional analyses. To overcome low light levels and the risk of phototoxicity, we employ quantitative phase imaging, a family of full-field imaging techniques that measure the optical path length shift introduced by the specimen. Specifically, we use spatial light interf...

A tidal bore develops in an estuary when the tidal range exceeds 4.5–6 m and the estuarine bathymetry amplifies the tidal wave. The bore is an abrupt rise in water depth associated with a discontinuity in velocity and pressure fields at the front. Herein the free-surface properties and the turbulent mixing of light-weight particles were investigated during the passage of tidal bores. The free-s...

The ATF2 project is the final focus system prototype for ILC and CLIC linear collider projects, with a purpose to reach a 37nm vertical beam size at the interaction point. During initial commissioning, we started with larger than nominal !-functions at the IP, to reduce the effects from higher-order optical aberrations and thereby simplify the optical corrections needed. We report on simulation...

Abstract. Recent inverse solutions obtained from some geoscience applications are presented. The estimation of the vertical atmospheric temperature from radiaces at infrared wavelenth is computed employing artificial neural networks, where good retrievals are obtained. A source-repector strategy is used for identifying the atmospheric pollutant source, where the Lagrangian particle model is app...

Atmospheric dispersion is a topic of great importance especially in relation to pollutant transport. Two different approaches, known as the Eulerian and the Lagrangian frameworks, are used to describe this process. In the Eulerian framework, statistical properties are calculated in a fixed reference frame. This approach is most commonly used in field experiments as well as in laboratory experim...

Since the start of flat-beam operation in 1993 typical vertical IP spot sizes in the SLC are well below 1 micron, and the luminosity is highly sensitive to dilutions of the vertical emittance. In the arcs, the ionization of the residual gas by the bunch head gives rise to an ion cloud, whose electric field deflects the tail of the bunch and may cause an unre-coverable filamentation in phase spa...

Coatings with vertical gradients in composition were produced by drying an aqueous polymer dispersion containing both charged and neutral particles. After drying, the neutral component was enriched at the film/air interface. The spontaneous vertical segregation between the two types of particles goes back to a difference in collective diffusivity. As the film dries, a layer enriched in polymer ...

We analyze price dispersion using panel data from a large comparison site. use past pricing behavior to instrument for potential endogeneity of firms select into certain product markets. Our main result is that greater adjustment costs in even e-commerce markets where cost are thought be negligible. Although the impact on became weaker over time, causal effect still present at end our observati...

Non-axisymmetric forces are presented for a sample of 107 spiral galaxies, of which 31 are barred (SB) and 53 show nuclear activity. As a database we use JHK images from the 2 Micron All Sky Survey, and the non-axisymmetries are characterized by the ratio of the tangential force to the mean axisymmetric radial force field, following Buta & Block (2001). Bar strengths have an important role in m...

Letter to the Editor The shape of galaxy disks: how the scale height increases with galactocentric distance Abstract. We present the results of a detailed study of vertical surface brightness profiles of edge-on disk galaxies. Although the exponential disk scale height is constant to first order approximation, we show that for the large majority of galaxies in our sample, the scale height incre...
