TL;DR: In this article, the authors present a first appraisal of the salient features of the TLEP physics potential, to serve as a baseline for a more extensive design study, and present a combination of TLEp and the VHE-LHC offers, for a great cost effectiveness, the best precision and the best search reach of all options presently on the market.
Abstract: The discovery by the ATLAS and CMS experiments of a new boson with mass around 125 GeV and with measured properties compatible with those of a Standard-Model Higgs boson, coupled with the absence of discoveries of phenomena beyond the Standard Model at the TeV scale, has triggered interest in ideas for future Higgs factories. A new circular e+e- collider hosted in a 80 to 100 km tunnel, TLEP, is among the most attractive solutions proposed so far. It has a clean experimental environment, produces high luminosity for top-quark, Higgs boson, W and Z studies, accommodates multiple detectors, and can reach energies up to the t-tbar threshold and beyond. It will enable measurements of the Higgs boson properties and of Electroweak Symmetry-Breaking (EWSB) parameters with unequalled precision, offering exploration of physics beyond the Standard Model in the multi-TeV range. Moreover, being the natural precursor of the VHE-LHC, a 100 TeV hadron machine in the same tunnel, it builds up a long-term vision for particle physics. Altogether, the combination of TLEP and the VHE-LHC offers, for a great cost effectiveness, the best precision and the best search reach of all options presently on the market. This paper presents a first appraisal of the salient features of the TLEP physics potential, to serve as a baseline for a more extensive design study.

TL;DR: This article assess the inter-temporal relationship between bank efficiency, capital and risk in a sample of European commercial banks employing several definitions of efficiency, risk and capital and using the Granger-causality methodology in a panel data framework.
Abstract: We assess the inter-temporal relationship between bank efficiency, capital and risk in a sample of European commercial banks employing several definitions of efficiency, risk and capital and using the Granger-causality methodology in a panel data framework. Our results suggest that lower bank efficiency with respect to costs and revenues Granger-causes higher bank risk and that increases in bank capital precede cost efficiency improvements. We also find that more efficient banks eventually become better capitalized and that higher capital levels tend to have a positive effect on efficiency levels. These results are generally confirmed by a series of robustness tests. The results have potentially important implications for bank prudential supervision and underline the importance of attaining long-term efficiency gains to support financial stability objectives.

TL;DR: In this article, a new catalogue of blazars based on multi-frequency surveys and on an extensive review of the literature is presented, which is useful for the identification of the extragala ctic sources that will be detected by present and future experiments for X and gamma-ray astronomy, like Swift, AGILE, Fermi-GLAST and Simbol-X.
Abstract: We present a new catalogue of blazars based on multi-frequency surveys and on an extensive review of the literature. Blazars are classified as BL Lacertae objects, as flat spectrum radio quas ars or as blazars of uncertain/transitional type. Each object is identified by a root name, coded as BZB, BZQ and BZU for these three subclasses respectively, and by its coordinates. This catalogue i s being built as a tool useful for the identification of the extragala ctic sources that will be detected by present and future experiments for X and gamma-ray astronomy, like Swift, AGILE, Fermi-GLAST and Simbol-X. An electronic version is available from the ASI Science Data Center web site at http://www.asdc.asi.it/bzcat.

TL;DR: After in vivo transplantation into immunocompromised rats, LAB formed lamellar bone‐containing osteocytes, which is an ideal source of osteoblasts and mineralized tissue for bone regeneration.
Abstract: Stem cells, derived from human adult dental pulp of healthy subjects 30-45 years of age, were cultured, and cells were selected using a FACSorter. A new c-kit+/CD34+/CD45− cell population of stromal bone producing cells (SBP/DPSCs) was selected, expanded, and cultured. These SBP/DPSCs are highly clonogenic and, in culture, differentiate into osteoblast precursors (CD44+/RUNX-2+), still capable of self-renewing, and then in osteoblasts, producing, in vitro, a living autologous fibrous bone (LAB) tissue, which is markedly positive for several bone antibodies. This tissue constitute an ideal source of osteoblasts and mineralized tissue for bone regeneration. In fact, after in vivo transplantation into immunocompromised rats, LAB formed lamellar bone-containing osteocytes.
Introduction: Recently it has been reported that human dental pulp stem cells (DPSCs) are detectable, in humans, only up to the age of 30 years and that they are able to produce in vitro only sporadic calcified nodules and to form, after transplantation in vivo, a mineralized tissue.
Materials and Methods: Stem cells, derived from human adult dental pulp of healthy subjects 30-45 years of age, were cultured, and cells were selected using a FACSorter. Light microscope, histochemistry, immunofluorescence, and RT-PCR analyses were performed to study both stem and differentiating cells.
Results and Conclusions: A new c-kit+/CD34+/CD45− cell population of stromal bone producing cells (SBP/DPSCs) has been selected by FACSorting, expanded, and cultured. These SBP/DPSCs are highly clonogenic and, in culture, differentiate into osteoblast precursors (CD44+/RUNX-2+), still capable of self-renewing, and in osteoblasts, producing, in vitro, a living autologous fibrous bone (LAB) tissue. This new-formed tissue is markedly positive for several antibodies for bone, including osteonectin, bone sialoprotein, osteocalcin, fibronectin, collagen III, and bone alkaline phosphatase (BALP). Cells producing LAB can be stored at −80°C for a long period of time and are an extraordinary source of osteoblasts and mineralized fibrous bone tissue. In this study, we also showed that, in aged humans, stem cells can be detected from their pulps. The produced LAB is a fibrous bone tissue resembling the human bone during mineralization, with an external layer formed by osteoblasts markedly positive for osteocalcin. This newly formed tissue constitute an ideal source of osteoblasts and mineralized tissue for bone regeneration. In fact, after in vivo transplantation into immunocompromised rats, LAB formed lamellar bone containing osteocytes.
