A convergence acceleration operator for multiobjective optimisation
A novel multiobjective optimisation accelerator is
introduced that uses direct manipulation in objective space
together with neural network mappings from objective space to decision space. This operator is a portable component that can be hybridized with any multiobjective optimisation algorithm. The purpose of this Convergence Acceleration Operator (CAO) is to enhance the search capability and the speed of convergence of the host algorithm. The operator acts directly in objective space to suggest improvements to solutions obtained by a multiobjective evolutionary algorithm (MOEA). These suggested improved objective vectors are then mapped into decision variable space and tested. The CAO is incorporated with two leading MOEAs, the Non-Dominated Sorting Genetic Algorithm (NSGA-II) and the Strength Pareto Evolutionary Algorithm (SPEA2) and tested. Results show that the hybridized algorithms consistently improve the speed of convergence of the original algorithm whilst maintaining the desired distribution of solutions

Chemotherapy-Related Chronic Myelogenous Leukemia: A Case Series of Patients With Germ Cell Tumor
Cover slip external cavity diode laser
The design of a 671 nm diode laser with a mode-hop-free tuning range of 40
GHz is described. This long tuning range is achieved by simultaneously ramping
the external cavity length with the laser injection current. The external
cavity consists of a microscope cover slip mounted on piezoelectric actuators.
In such a configuration the laser output pointing remains fixed, independent of
its frequency. Using a diode with an output power of 5-7 mW, the laser
linewidth was found to be smaller than 30 MHz. This cover slip cavity and
feedforward laser current control system is simple, economical, robust, and
easy to use for spectroscopy, as we demonstrate with lithium vapor and lithium
atom beam experiments.Comment: 7 pages, 6 figures, submitted to Review of Scientific Instruments

Controlling the electronic structure of graphene using surface-adsorbate interactions
We show that strong coupling between graphene and the substrate is mitigated
when 0.8 monolayer of Na is adsorbed and consolidated on top
graphene-on-Ni(111). Specifically, the {\pi} state is partially restored near
the K-point and the energy gap between the {\pi} and {\pi}* states reduced to
1.3 eV after adsorption, as measured by angle-resolved photoemission
spectroscopy. We show that this change is not caused by intercalation of Na to
underneath graphene but it is caused by an electronic coupling between Na on
top and graphene. We show further that graphene can be decoupled to a much
higher extent when Na is intercalated to underneath graphene. After
intercalation, the energy gap between the {\pi} and {\pi}* states is reduced to
0 eV and these states are identical as in freestanding and n-doped graphene. We
conclude thus that two mechanisms of decoupling exist: a strong decoupling
through intercalation, which is the same as one found using noble metals, and a
weak decoupling caused by electronic interaction with the adsorbate on top
Metastatic small cell carcinoma of the prostate in an octogenarian with significant response to first-line chemotherapy
Patients with small cell carcinoma of the prostate generally present with metastatic disease and have an estimated life expectancy measured in months. In this brief report, we present a case of rapidly progressive metastatic small cell carcinoma of the prostate in an octogenarian with significant response to split-dosed cisplatin and etoposide. This case report shows that cautious treatment with platinum-based regimens should still be considered in elderly patients given the potential for improvement in performance status and quality of life with chemotherapy. Additionally, this case highlights that platinum-based regimens are still considered the therapeutic backbone of prostate cancers with a mixed small cell carcinoma and adenocarcinoma phenotype
Espace-PV: Key Sensitive Parameters for Environmental Impacts of Grid-Connected PV Systems With LCA
http://www.eupvsec-proceedings.com/proceedings?char=E&paper=2818International audienceThe study of sensitive parameters for the life cycle analysis (LCA) of PV system showed that irradiation intensity will bring the biggest variation on environmental impact when considering regions with large difference in solar irradiation level. For example, in France a system installed in the northern region will produce electricity with more than a 100% of the impact of a southern system. Other important factors are the lifetime of the system and the associated electricity use for the different components needed for the PV system. They can bring up to 35% of variation in the production of CO2 gas and primary non-renewable energy use. This study has been developed within Espace-PV project and results have been analyzed and compared with the EcoInvent database. These results are provided for a 3 kWp multicrystalline grid connected system integrated in a slanted roof with near optimal inclination

Immunomodulation by Mesenchymal Stem Cells A Potential Therapeutic Strategy for Type 1 Diabetes
Mesenchymal stem cells (MSCs) are pluripotent stromal cells that have the potential to give rise to cells of diverse lineages. Interestingly, MSCs can be found in virtually all postnatal tissues. The main criteria currently used to characterize and identify these cells are the capacity for self-renewal and differentiation into tissues of mesodermal origin, combined with a lack in expression of certain hematopoietic molecules. Because of their developmental plasticity, the notion of MSC-based therapeutic intervention has become an emerging strategy for the replacement of injured tissues. MSCs have also been noted to possess the ability to impart profound immunomodulatory effects in vivo. Indeed, some of the initial observations regarding MSC protection from tissue injury once thought mediated by tissue regeneration may, in reality, result from immunomodulation. Whereas the exact mechanisms underlying the immunomodulatory functions of MSC remain largely unknown, these cells have been exploited in a variety of clinical trials aimed at reducing the burden of immune-mediated disease. This article focuses on recent advances that have broadened our understanding of the immunomodulatory properties of MSC and provides insight as to their potential for clinical use as a cell-based therapy for immune-mediated disorders and, in particular, type 1 diabetes
Environmental Impact of PV Systems: Effects of Energy Sources Used in Production of Solar Panels
http://www.eupvsec-proceedings.com/proceedings?char=E&paper=4860International audienceThe international expansion of the PV industry can affect the range of indirect environmental impacts, and mostly the CO2 equivalent emissions, of the solar electricity produced in any country. We demonstrate a clear trend towards high variation in the global warming potential of solar electricity produced in France by PV installations which use modules produced with different electricity mix. The variation is somewhat less important when looking at the Energy Payback Time (EPBT) of the PV installation. In any studied case, the transportation between countries has a low effect compared to the choice made on the source of electricity used during the different steps involved in the fabrication of modules for any technology
