The invention concerns a method and a device wherein a stencil is provided with an integrated microhotplate on the stencil membrane to prevent aperture clogging, whereby the stencil can be locally heated up in order to minimize material condensation, remov ...
The present invention relates to a method for assessing the quality, utility and applicability of a cell according to the said method comprising the following steps: a) analyzing the expression of the TEs of said cell in order to set up an expression profi ...
This paper revisits the Doctrine of Public Cybersecurity in order to shed light on debates about information sharing, by exploring its potential utility, and considering policies to mitigate its impact on other societal values. Its goal is not to advocate ...
Divergence-form operators with stationary random coefficients homogenize over large scales. We investigate the effect of certain perturbations of the medium on the homogenized coefficients. The perturbations considered are rare at the local level, but when ...
In [1], an important step toward the characterization of distributed detection over adaptive networks has been made by establishing the fundamental scaling law of the error probabilities. However, empirical evidence reported in [1] revealed that a refined ...
In this paper we give a new proof of the ELSV formula. First, we refine an argument of Okounkov and Pandharipande in order to prove (quasi-)polynomiality of Hurwitz numbers without using the ELSV formula (the only way to do that before used the ELSV formul ...
A method based on phase-sensitive OTDR is proposed for distributed birefringence measurements along optical fibres. A high accuracy is experimentally demonstrated, enabling the characterisation of single-mode fibres with a minimum detectable birefringence ...
In a dramatic crisis context, Lisbon reveals itself as an attractive and dynamic city of alternative bustling creativity. Trying to understand this paradox, I analyse two successful “alternative cultural spaces”: Lx Factory and Pensão Amor. Urban strategie ...
GaAs nanowires were heated locally under ambient air conditions by a focused laser beam which led to oxidation and formation of crystalline arsenic on the nanowire surface. Atomic force microscopy, photoluminescence and Raman spectroscopy experiments were ...
During the commissioning of the CERN Proton Synchrotron multiturn extraction, tests with different beam intensities were performed in order to probe the behavior of resonance crossing in the presence of possible space charge effects. The initial beam inten ...
