Thermal evolution and structure models of the transiting super-Earth GJ 1214b

The planet GJ 1214b is the second known super-Earth with a measured mass and radius. Orbiting a quiet M-star, it receives considerably less mass-loss driving X-ray and UV radiation than CoRoT-7b, so that the interior may be quite dissimilar in composition, including the possibility of a large fraction of water. We model the interior of GJ 1214b assuming a two-layer (envelope+rock core) structure where the envelope material is either H/He, pure water, or a mixture of H/He and H2O. Within this framework we perform models of the thermal evolution and contraction of the planet. We discuss possible compositions that are consistent with Mp=6.55 ME, Rp=2.678 RE, an age tau=3-10 Gyr, and the irradiation level of the atmosphere. These conditions require that if water exists in the interior, it must remain in a fluid state, with important consequences for magnetic field generation. These conditions also require the atmosphere to have a deep isothermal region extending down to 80-800 bar, depending on composition. Our results bolster the suggestion of a metal-enriched H/He atmosphere for the planet, as we find water-world models that lack an H/He atmosphere to require an implausibly large water-to-rock ratio of more than 6:1. We instead favor a H/He/H2O envelope with high water mass fraction (~0.5-0.85), similar to recent models of the deep envelope of Uranus and Neptune. Even with these high water mass fractions in the H/He envelope, generally the bulk composition of the planet can have subsolar water:rock ratios. Dry, water-enriched, and pure water envelope models differ to an observationally significant level in their tidal Love numbers k2 of respectively ~0.018, 0.15, and 0.7.Comment: 11 pages, 6 figures, 1 table, accepted to Ap

Proposed statement on auditing standards : generally accepted auditing standards : (supersedes Generally accepted auditing standards of Statement on auditing standards no. 1, Codification of auditing standards and procedures, AICPA, Professional standards, vol. 1, AU sec. 150);Generally accepted auditing standards : (supersedes Generally accepted auditing standards of Statement on auditing standards no. 1, Codification of auditing standards and procedures, AICPA, Professional standards, vol. 1, AU sec. 150); Exposure draft (American Institute of Certified Public Accountants), 2001, May 4

The body of auditing literature grew and evolved considerably during the twentieth century. American Institute of Certified Public Accountants (AICPA) boards and committees have issued ninety-three Statements on Auditing Standards (SASs), some of which have been superseded, and numerous auditing interpretations. The AICPA also has published Auditing Statements of Position, Audit and Accounting Guides and numerous other publications containing guidance of varying authority on how to conduct an audit of financial statements in accordance with generally accepted auditing standards (GAAS). Although the AICPA has, on occasion, realigned and clarified the authority of these publications, some uncertainty remains in the minds of auditors and others about which publications auditors must know and follow when conducting an audit. Furthermore, because of the large volume of auditing publications, some auditors may not be aware of publications that may be applicable to their audit engagements. The Auditing Standards Board (ASB) believes the proposed SAS will significantly reduce uncertainty about which publications the auditor must comply with and which publications the auditor must consider when performing an audit in accordance with GAAS. The ASB also expects that auditors will become more aware of other applicable auditing publications that may provide useful auditing guidance, increasing the likelihood that auditors will use them. All of this should result in increased audit quality. The proposed SAS: 1. Identifies the body of auditing literature. 2. Clarifies the authority of auditing publications issued by the AICPA and others. 3. Specifies which auditing publications the auditor must comply with and those he or she must consider when conducting an audit in accordance with GAAS. 4. Identifies specific AICPA auditing publications and provides information on how to obtain them. This proposed SAS would supersede SAS No. 1, Codification of Auditing Standards and Procedures, AU section 150, Generally Accepted Auditing Standards. Certain other descriptions of the authority of AICPA auditing publications also will be revised to conform to the descriptions included in the proposed SAS. These include the head note in AU Section 100, Statements on Auditing Standards - Introduction (AICPA, Professional Standards, vol. 1, AU sec. 100), the authority statement included at the end of each newly-published SASs, the Notice to Readers included in AICPA Audit and Accounting Guides and AICPA Audit Guides, and certain other notices and authority statements included in other AICPA auditing publications.https://egrove.olemiss.edu/aicpa_sop/1282/thumbnail.jp

Histopathologic investigation of the protective effects of omega-3 fatty acids against boric acid-induced injury in kidney and testis tissue

Objective: In this study, it was aimed to evaluate the effects of boric acid on rat kidney and testis tissues histopathologically. Secondly, the protective effects of omega-3 fatty acid against boric acid-induced renal and testicular toxicity were investigated. Methods: 32 wistar albino rats were divided into 4 groups as follows: Control, Omega-3 (400 mg/kg/day for 10 days), Boric acid (375 mg/kg/day for 10 days) and Boric acid+omega-3 (both drugs same dosage for same day). Kidney and testis tissues were evaluated using a scoring system based on the extent of certain histopathological changes. Results: In histopathological examination, boric acid caused significant degeneration in both testis and kidney tissues. Most evident findings were glomerular shrinkage and necrosis, hemorrhage and tubular cell degeneration in kidneys, and exfoliation of seminiferous tubule cells, detachement of epithelium from basement membrane, decreased cellularity and degeneration in epithelial cells in testis tissues. Omega-3 administration significantly attenuated these changes. Conclusion: To our literature search, this is the first study reporting protective effects of omega-3 fatty acid against boric-acid-induced testicular and renal injury

Long-term Monitoring on Mrk 501 for Its VHE gamma Emission and a Flare in October 2011

As one of the brightest active blazars in both X-ray and very high energy $\gamma$-ray bands, Mrk 501 is very useful for physics associated with jets from AGNs. The ARGO-YBJ experiment is monitoring it for $\gamma$-rays above 0.3 TeV since November 2007. Starting from October 2011 the largest flare since 2005 is observed, which lasts to about April 2012. In this paper, a detailed analysis is reported. During the brightest $\gamma$-rays flaring episodes from October 17 to November 22, 2011, an excess of the event rate over 6 $\sigma$ is detected by ARGO-YBJ in the direction of Mrk 501, corresponding to an increase of the $\gamma$-ray flux above 1 TeV by a factor of 6.6$\pm$2.2 from its steady emission. In particular, the $\gamma$-ray flux above 8 TeV is detected with a significance better than 4 $\sigma$. Based on time-dependent synchrotron self-Compton (SSC) processes, the broad-band energy spectrum is interpreted as the emission from an electron energy distribution parameterized with a single power-law function with an exponential cutoff at its high energy end. The average spectral energy distribution for the steady emission is well described by this simple one-zone SSC model. However, the detection of $\gamma$-rays above 8 TeV during the flare challenges this model due to the hardness of the spectra. Correlations between X-rays and $\gamma$-rays are also investigated.Comment: have been accepted for publication at Ap

Article A new microendemic frog species of the genus Blommersia (Anura: Mantellidae) from the east coast of Madagascar

Abstract Field surveys in northeastern Madagascar have revealed the existence of a new Blommersia frog species (Anura: Mantellidae), populations of which were recorded within a 30 km radius of the town of Maroantsetra. We combined morphological, bioacoustic and molecular techniques and show that it is indeed a distinct evolutionary lineage which we describe as Blommersia variabilis sp. nov. from the type locality Ambodivoahangy near Maroantsetra. This new species is morphologically most similar to B. wittei by the presence of vomerine teeth and relatively small, well-delimited femoral glands, but differs from that species by advertisement call consisting of only 2-6 notes of comparatively longer duration, and a wider separation of femoral glands in males. It is associated with dense secondary vegetation fringing lentic water bodies. Anecdotal evidence suggests its life history is similar to other congeners. The restricted range of this species implies that it is microendemic, being possibly confined to the Antainambalana watershed. Mitochondrial and nuclear DNA variation show that its closest known relatives are Blommersia galani and B. dejongi, both of which also have restricted ranges on the east coast. A putative hybrid between a B. galani female and B. dejongi male with intermediate morphology was identified based on nuclear and mitochondrial DNA variation
