Photolabile coumarins with improved efficiency through azetidinyl substitution

Pablo Rivera Fuentes, Zacharias Thiel, Eric Vauthey

Azetidinyl substituents have been recently used to improve the fluorescence quantum yield of several classes of fluorophores. Herein, we demonstrate that other useful photochem. processes can be modulated using this strategy. In particular, we prepd. and m ...

Alloy development of a new platinum-based bulk metallic glass

Hamed Kazemi

The aim of the present thesis is the development of a new Pt-based bulk metallic glass based on the ternary system of Pt-B-Si that i) complies with the hallmarking standard Pt 850 (i.e. with at least 85 wt.-pct of Pt); ii) provides high hardness (HV>600) a ...

Enhanced Rate of Acquisition of Point Mutations in Mouse Intestinal Adenomas Compared to Normal Tissue

Paloma Ordonez Moran

The most prevalent single-nucleotide substitution (SNS) found in cancers is a C-to-T substitution in the CpG motif. It has been proposed that many of these SNSs arise during organismal aging, prior to transformation of a normal cell into a precancerous/can ...

Evaluating direct transcription and nonlinear optimization methods for robot motion planning

Jonas Buchli, Alexander Winkler

This paper studies existing direct transcription methods for trajectory optimization for robot motion planning. These methods have demonstrated to be favorable for planning dynamically feasible motions for high dimensional robots with complex dynamics. How ...

Solid Solutions of Lead Metaniobate-Stabilization of the Ferroelectric Polymorph and the Effect on the Lattice Parameters, Dielectric, Ferroelectric, and Piezoelectric Properties

Nava Setter, Dragan Damjanovic, Alberto Biancoli, Barbara Maraston Fraygola, Mtabazi Geofrey Sahini

Ferroelectric orthorhombic lead metaniobate (PbNb2O6) is known to be metastable with respect to the thermodynamically stable nonferroelectric rhombohedral polymorph. The high-temperature tetragonal to low temperature rhombohedral phase transition is recons ...

Gaussian upper density estimates for spatially homogeneous SPDEs

We consider a general class of SPDEs in mathbb{R}^d driven by a Gaussian spatially homogeneous noise which is white in time. We provide sufficient conditions on the coefficients and the spectral measure associated to the noise ensuring that the density of ...

Left-inverses of fractional Laplacian and sparse stochastic processes

Michaël Unser

The fractional Laplacian (-Delta)(gamma/2) commutes with the primary coordination transformations in the Euclidean space Rd: dilation, translation and rotation, and has tight link to splines, fractals and stable Levy processes. For 0 < gamma < d, its inver ...

Multipurpose Cryptographic Primitive ARMADILLO3

Serge Vaudenay, Petr Susil

This paper describes a new design of the multipurpose cryptographic primitive ARMADILLO3 and analyses its security. The ARMADILLO3 family is oriented on small hardware such as smart cards and RFID chips. The original design ARMADILLO and its variants were ...

Electromechanical properties of Al0.9Sc0.1N thin films evaluated at 2.5 GHz film bulk acoustic resonators

Paul Muralt, Ramin Matloub Aghdam, Silviu Cosmin Sandu, Alvaro Artieda, Evgeny Milyutin

AlN films are employed in RF filters for wireless communication. We report on enhanced coupling factors k(t)(2) obtained by partial substitution of Al by Sc. Al0.88Sc0.12N films were deposited by reactive magnetron sputtering from an Al0.9Sc0.1 alloy targe ...
