TL;DR: In this article, a very high energy (VHE) gamma-ray signal was detected from SN 1006, which is consistent with the previously established H.E.S. upper limit, thus motivating further in-depth observations of this source.
Abstract: Recent theoretical predictions of the lowest very high energy (VHE) luminosity of SN 1006 are only a factor 5 below the previously published H.E.S.S. upper limit, thus motivating further in-depth observations of this source. Deep observations at VHE energies (above 100 GeV) were carried out with the High Energy Stereoscopic System (H.E.S.S.) of Cherenkov Telescopes from 2003 to 2008. More than 100 hours of data have been collected and subjected to an improved analysis procedure. Observations resulted in the detection of VHE gamma-rays from SN 1006. The measured gamma-ray spectrum is compatible with a power-law, the flux is of the order of 1% of that detected from the Crab Nebula, and is thus consistent with the previously established H.E.S.S. upper limit. The source exhibits a bipolar morphology, which is strongly correlated with non-thermal X-rays. Because the thickness of the VHE-shell is compatible with emission from a thin rim, particle acceleration in shock waves is likely to be the origin of the gamma-ray signal. The measured flux level can be accounted for by inverse Compton emission, but a mixed scenario that includes leptonic and hadronic components and takes into account the ambient matter density inferred from observations also leads to a satisfactory description of the multi-wavelength spectrum.

TL;DR: Results indicate that RGP-1 is the major VPE factor of P. gingivalis, inducing this activity through PK activation and subsequent BK release, resulting in GCF production at sites of periodontitis caused by infection with this organism.
Abstract: To elucidate the mechanism of production of an inflammatory exudate, gingival crevicular fluid (GCF), from periodontal pockets in periodontitis, we examined the vascular permeability enhancement (VPE) activity induced by an arginine-specific cysteine proteinase, Arg-gingipain-1 (RGP-1), produced by a major periopathogenic bacterium, Porphyromonas gingivalis. Intradermal injections into guinea pigs of RGP-1 (> 10(-8) M), or human plasma incubated with RGP-1 (> 10(-9) M), induced VPE in a dose- and activity-dependent manner but with different time courses for the two routes of production. VPE activity induced by RGP-1 was augmented by kininase inhibitors, inhibited by a kallikrein inhibitor and unaffected by an antihistamine drug. The VPE activity in human plasma incubated with RGP-1 also correlated closely with generation of bradykinin (BK). RGP-1 induced 30-40% less VPE activity in Hageman factor-deficient plasma and no VPE in plasma deficient in either prekallikrein (PK) or high molecular weight kininogen (HMWK). After incubation with RGP-1, plasma deficient in PK or HMWK, reconstituted with each missing protein, caused VPE, as did a mixture of purified PK and HMWK, but RGP-1 induced no VPE from HMWK. The VPE of extracts of clinically isolated P. gingivalis were reduced to about 10% by anti-RGP-1-IgG, leupeptin, or tosyl-L-lysine chloromethyl ketone, which paralleled effects observed with RGP-1. These results indicate that RGP-1 is the major VPE factor of P. gingivalis, inducing this activity through PK activation and subsequent BK release, resulting in GCF production at sites of periodontitis caused by infection with this organism.

TL;DR: In this article, the authors propose to use of five group indicators for measuring regional CE-eco-innovation, based on Eco-Innovation Scoreboard which describes innovation measurement.
Abstract: The concept of a circular economy (CE) has become popular and important issue in environmental management in recent years; however, there are not particular indicators dedicated to it in regional policy. CE approach is an industrial system that is restorative by design, and it emphasises that it is important that, rather than extracting natural resources, the materials that have already been taken can and should be recovered and reused in different ways, thereby securing natural resources from over-exploitation. In order to meet CE assumptions, modern and innovative technologies that allow for the recovery of valuable materials should be developed. This also applies to eco-innovation that connects technology development with environmental aspects. It is therefore obvious that issues of CE and eco-innovation are linked, and a uniform methodology aimed at compare the levels of moving to CE including eco-innovation solutions should be established. Because the focus in European Union (EU) has been paid on regions, measuring of CE–eco-innovations levels is especially important at the regional level. In this paper, the proposals of CE indicators, based on eco-innovation factors, which can be possible to create based on existing data set (Eurostat, Cohesion policy) are presented. It is recommend to use of five group indicators for measuring regional CE–eco-innovation. Based on Eco-Innovation Scoreboard which describes innovation measurement, three of proposed indicator groups are associated directly with innovations, taking into account the principles of CE: CE–eco-innovation inputs, CE–eco-innovation activities and CE–eco-innovation outputs, and other two groups of indicators are effects of the CE–eco-innovation introduction: resource efficiency outcomes and socio-economic outcomes. This way of measuring CE–eco-innovation allows for create holistic, systematic and integrated approach for the CE concept at the regional level. Proposed indicators can be used in current transition stage for assessment of implementation regional policy and as a base for creation final CE indicators.

TL;DR: Combined 95% confidence-level upper limits are set on the production cross section for a range of vectorlike quark scenarios, significantly improving upon the reach of the individual searches.
Abstract: A combination of the searches for pair-produced vectorlike partners of the top and bottom quarks in various decay channels (T -> Zt/Wb/Ht, B -> Zb/Wt/Hb) is performed using 36.1 fb(-1) of pp ...
