Microstructure Formation in Sn-Cu-Ni Solder Alloys

Michel Rappaz, Milan Felberbaum, Tina Ventura

A systematic study of the solidification mechanisms of binary Sn-Cu and ternary Sn-Cu-Ni alloys has been carried out. It is found that Sn-Cu is a weakly-irregular eutectic system with Cu6Sn5 as the leading phase. Interestingly, two different eutectic morph ...

Analysis of Solid Oxide Fuel Cell LSM-YSZ Composite Cathodes With Varying Starting Powder Sizes

Christos Comninellis, Jan Van Herle, Pietro Tanasini

Solid oxide fuel cell cathodes have been examined using non-destructive x-ray nanotomography. The cathodes examined were a composite of strontium-doped lanthanum manganite (LSM) and yttria-stabilized zirconia (YSZ), with three different starting powder siz ...

In vitro and in vivo photocytotoxicity of boron dipyrromethene derivatives for photodynamic therapy

Hubert van den Bergh, Georges Wagnières, Patrycja Nowak-Sliwinska, Siang Hui Lim

To understand the effects of substitution patterns on photosensitizing the ability of boron dipyrromethene (BODIPY), two structural variations that either investigate the effectiveness of various iodinated derivatives to maximize the "heavy atom effect" or ...

Culture conditions affect fatty acid content along with wound-activated production of polyunsaturated aldehydes in Thalassiosira rotula (Coscinodiscophyceae)

The nutritional value of diatoms for grazers has been frequently addressed in experiments. However, little is known about the effects of culture conditions on the quality of algae as food for higher trophic levels. We examined the fatty acid composition of ...

The ATAC acetyl transferase complex controls mitotic progression by targeting non-histone substrates

Mathias Fournier

All DNA-related processes rely on the degree of chromatin compaction. The highest level of chromatin condensation accompanies transition to mitosis, central for cell cycle progression. Covalent modifications of histones, mainly deacetylation, have been imp ...

Comparative Study of Three Bayesian Filtering Approaches for Phase Step Estimation in Optical Interferometry

Pramod Rastogi, Abhijit Patil

This paper presents three recursive Bayesian filtering approaches in phase shifting interferometry involving a piezoelectric device (PZT). The three approaches are extended Kalman filtering, unscented Kalman filtering, and particle filtering. These approac ...

How adeno-associated virus Rep78 relocalises Cdc25B to arrest the cell cycle

Florence Magnin

Adeno-associated virus (AAV) is a small DNA virus belonging to the family of the parvoviridae. AAV infects the human population, however no disease has been associated with this virus. On the contrary, AAV was reported to have oncosuppressive activities. T ...

Nucleosome eviction from MHC class II promoters controls positioning of the transcription start site

Giovanna Ambrosini, Philipp Bucher

Nucleosome depletion at transcription start sites (TSS) has been documented genome-wide in multiple eukaryotic organisms. However, the mechanisms that mediate this nucleosome depletion and its functional impact on transcription remain largely unknown. We h ...

Coupling the cell cycle to development

Pierre Gönczy, Yemima Suryani Budirahardja

The core machinery that drives the eukaryotic cell cycle has been thoroughly investigated over the course of the past three decades. It is only more recently, however, that light has been shed on the mechanisms by which elements of this core machinery are ...

Lte1, Cdc14 and MEN-controlled Cdk inactivation in yeast coordinate rDNA decompaction with late telophase progression

Thierry Laroche

The mechanism of chromatin compaction in mitosis has been well studied, while little is known about what controls chromatin decompaction in early G1 phase. We have localized the Condensin subunit Brn1 to a compact spiral of rDNA in mitotic budding yeast ce ...
