Fluorescence of the bladder washout fluid following cystoscopy: a preliminary study

Hubert van den Bergh, Georges Wagnières, Anna Maria Novello, Blaise Lovisa

During fluorescence cystoscopy, it is observed that the acquired images are sometimes blurred by a greenish background originating from the bladder washout fluid. Several fluorophores are involved in this overall liquid fluorescence, and their exact origin ...

Comment on 'The effect of evaporation on the wicking of liquids into a metallic weave' by N. Fries, K. Odic, M. Conrath and M. Dreyer

David Andrew Barry, Laurin Wissmeier

A recent paper reported capillary rise and evaporation experiments in metallic wicks, as well as a mathematical model. The authors found a consistent discrepancy between the model predictions and data: The model over-predicted the capillary height rise by ...

Drying front and water content dynamics during evaporation from sand delineated by neutron radiography

Dani Or, Nima Shokri

Evaporative drying of porous media is jointly controlled by external ( atmospheric) conditions and by media internal transport properties. Effects of different atmospheric potential evaporative demand on observed drying rates were studied in a series of la ...

Evaluating automated parameter constraining procedures of neuron models by experimental and surrogate data

Henry Markram, Felix Schürmann, Sean Lewis Hill, Thomas Berger, Idan Segev

Neuron models, in particular conductance-based compartmental models, often have numerous parameters that cannot be directly determined experimentally and must be constrained by an optimization procedure. A common practice in evaluating the utility of such ...

A virtual valve for smooth contamination-free flow switching

Philippe Renaud, Thomas Michael Braschler, Harald Van Lintel, Nicolas Demierre, Anja Kunze, Raphaël Tornay, Joël Theytaz, Mario Schlund, Grazia Loche

We present a channel geometry that allows for clean switching between different inlets of a microchip without any contamination of the inlets or the downstream flow. We drive this virtual valve with a pneumatic pressure setup that minimizes disturbance of ...

Simulation of the flow-reversal effect in dual-channel CICC for ITER

Pierluigi Bruzzone, Luca Bottura

The discovery of an upward counter flow of helium in the outer annulus of the vertically oriented and top-to-bottom cooled ITER PF-FSJS (Poloidal Field Coil-Full Size Joint Sample) in 2002 led to closer investigations of the effect because it may lead to a ...

The non-circular shape of FloWatch®-PAB prevents the need for pulmonary artery reconstruction after banding

Alfio Quarteroni, Paolo Zunino, Ludwig Von Segesser

To evaluate the differences between non-circular shape of FloWatch®-PAB and conventional pulmonary artery (PA) banding. Methods: Geometrical analysis. Conventional banding and FloWatch®-PAB perimeters were plotted against cross-sections. Computational flui ...

INTERACTION OF A CAVITATION BUBBLE WITH A SPHERICAL FREE SURFACE

Mohamed Farhat, Nicolas Dorsaz, Danail Obreschkow, Philipp Kobel, Aurèle De Bosset

The dynamic of a cavitation bubble inside a water drop is investigated in microgravity in order to analyze the interaction between the collapsing bubble and a quasispherical free surface. Tests are carried in the frame of the 42nd parabolic flight campaign ...

Deformation mechanisms of silicon during nanoscratching

Christophe Ballif, Johann Michler

The deformation mechanisms of silicon {001} surfaces during nanoscratching were found to depend strongly on the loading conditions. Nanoscratches with increasing load were performed at 2 μm/s (low velocity) and 100 μm/s (high velocity). The load-penetratio ...

Practical Cryptography in High Dimensional Tori

Robert Granger, Martijn Stam

At Crypto 2004, van Dijk and Woodruff introduced a new way of using the algebraic tori

T_n

in cryptography, and obtained an asymptotically optimal

n/\phi(n)

savings in bandwidth and storage for a number of cryptographic applications. However, the compu ...
