Improved sperm selection techniques are needed to increase the efficiency of equineassisted reproduction. Single layer centrifugation (SLC) of spermatozoa has been shown to improve the quality of stallion sperm samples. In this study, the functionality of selected stallion spermatozoa was tested by intracytoplasmic sperm injection of equine oocytes after selection by SLC through Androcoll-E or ...

Automated machine learning (AutoML) supports the algorithmic construction and data-specific customization of pipelines, including selection, combination, parametrization algorithms as main constituents. Generally speaking, AutoML approaches comprise two major components: a search space model an optimizer for traversing space. Recent have shown impressive results in realm supervised learning, mo...

Precision tests of the electroweak interactions will soon be possible at the SLC and LEP. The SLC will be capable of providing longitudinal polarization of one incoming beam, the electrons, for such tests. Plans at the SLC to provide and monitor these beams are described, and some physics objectives are discussed. Invited talk presented at the Workshop on Tests of Electroweak Theories, Polarize...

Mouse 6Ckine/SLC (secondary lymphoid tissue chemokine) is a chemotactic factor for dendritic cells, T cells, and NK cells in vitro. In addition, mouse 6Ckine/SLC interacts with the chemokine receptor CXCR3, as do several chemokines with antiangiogenic properties. These dual properties of mouse 6Ckine/SLC were tested for the induction of an antitumor response by transducing the C26 colon carcino...

Dendritic cell (DC)-based immunotherapy is regarded as a promising means for anti-cancer therapy. The efficiency of T cell-priming in vivo by transferred DCs should depend on their encounter with T cells. In the present study, we attempted to improve the capacity of DCs to prime T cells in vivo by genetic modification to express chemokine with a T cell-attracting property. For genetic modificat...

Sea level change (SLC) real-time monitoring has being developed and improved for the Portuguese tide gauge, based in FTP access to the internet server of the Portuguese geographical institute. A software application, named MareVB and in development since 2008, gets a 3 minute stream input of sea level height and a 10 minute stream input of air-pressure. Based on a predicted tide model, the sea ...

BACKGROUND Good quality spermatozoa are important to achieve fertilization, viable embryos and offspring. Single Layer Centrifugation (SLC) through a colloid (Androcoll-P) selects good quality spermatozoa. However, it has not been established previously whether porcine spermatozoa selected by this method maintain their fertility. METHODS The semen was prepared either by SLC or by standard cen...

One of the most compelling visual phenomena is simultaneous lightness contrast (SLC). The observation that grey looks darker when set against white than when set against black has intrigued philosophers and scientists for two millennia (see Wade 1996), yet there is still no consensus as to exactly why it happens. In a renaissance of interest in the effects of context on surface colour appearanc...

As we seek both to improve public school education in high technology areas and to link libraries and classrooms on the “information superhighway,” we need to understand more about children’s information searching abilities. We present results of four experiments conducted on four versions of the Science Library Catalog (SLC), a Dewey decimal-based hierarchical browsing system implemented in Hy...
