TL;DR: The Fermi Large Area Telescope (Fermi-LAT, hereafter LAT), the primary instrument on the FermI Gamma-ray Space Telescope (fermi) mission, is an imaging, wide field-of-view, high-energy \gamma-ray telescope, covering the energy range from 20 MeV to more than 300 GeV as discussed by the authors.
Abstract: The Fermi Large Area Telescope (Fermi-LAT, hereafter LAT), the primary instrument on the Fermi Gamma-ray Space Telescope (Fermi) mission, is an imaging, wide field-of-view, high-energy \gamma-ray telescope, covering the energy range from 20 MeV to more than 300 GeV. During the first years of the mission the LAT team has gained considerable insight into the in-flight performance of the instrument. Accordingly, we have updated the analysis used to reduce LAT data for public release as well as the Instrument Response Functions (IRFs), the description of the instrument performance provided for data analysis. In this paper we describe the effects that motivated these updates. Furthermore, we discuss how we originally derived IRFs from Monte Carlo simulations and later corrected those IRFs for discrepancies observed between flight and simulated data. We also give details of the validations performed using flight data and quantify the residual uncertainties in the IRFs. Finally, we describe techniques the LAT team has developed to propagate those uncertainties into estimates of the systematic errors on common measurements such as fluxes and spectra of astrophysical sources.

TL;DR: The integration of the spatial information from the watershed segmentation in the hyperspectral image classifier improves the classification accuracies and provides classification maps with more homogeneous regions, compared to pixel-wise classification and previously proposed spectral-spatial classification techniques.

TL;DR: The recommendations for the management of LVV have been updated to facilitate the translation of current scientific evidence and expert opinion into better management and improved outcome of patients in clinical practice.
Abstract: BACKGROUND
Since the publication of the European League Against Rheumatism (EULAR) recommendations for the management of large vessel vasculitis (LVV) in 2009, several relevant randomised clinical trials and cohort analyses have been published, which have the potential to change clinical care and therefore supporting the need to update the original recommendations.
METHODS
Using EULAR standardised operating procedures for EULAR-endorsed recommendations, the EULAR task force undertook a systematic literature review and sought opinion from 20 experts from 13 countries. We modified existing recommendations and created new recommendations.
RESULTS
Three overarching principles and 10 recommendations were formulated. We recommend that a suspected diagnosis of LVV should be confirmed by imaging or histology. High dose glucocorticoid therapy (40-60 mg/day prednisone-equivalent) should be initiated immediately for induction of remission in active giant cell arteritis (GCA) or Takayasu arteritis (TAK). We recommend adjunctive therapy in selected patients with GCA (refractory or relapsing disease, presence of an increased risk for glucocorticoid-related adverse events or complications) using tocilizumab. Methotrexate may be used as an alternative. Non-biological glucocorticoid-sparing agents should be given in combination with glucocorticoids in all patients with TAK and biological agents may be used in refractory or relapsing patients. We no longer recommend the routine use of antiplatelet or anticoagulant therapy for treatment of LVV unless it is indicated for other reasons.
CONCLUSIONS
We have updated the recommendations for the management of LVV to facilitate the translation of current scientific evidence and expert opinion into better management and improved outcome of patients in clinical practice.

TL;DR: The most common stoichiometric determination during formulation studies is 1:1, i.e. one drug molecule forms a complex with one cyclodextrin molecule, and the apparent stability constant (K1:1) of the 1:2 drug/cyclodextrins complexes calculated by the phase-solubility method is found.

TL;DR: Organ transplant recipients are at a highly increased risk for non‐melanoma skin cancer and must be closely followed throughout their lives, even among populations living in regions with low solar insolation.
Abstract: Background Skin cancer following solid organ transplantation is an important cause of morbidity in long-term survivors. This risk is well known but imprecisely quantified. Objectives We aimed to determine: (i) the skin cancer risks in transplant patients more precisely; (ii) whether the risk of malignant melanoma is altered; and (iii) whether the risk of epithelial cancers occurring at non-exposed sites is comparable with that seen in sun-exposed sites. Methods We linked a population-based cohort of 5356 patients who had received organ transplants in Sweden between 1970 and 1994 with the compulsory Swedish Cancer Registry, to identify all cancer cases except basal cell carcinomas, which are not registered. Results After a mean follow-up of 5.6 years post-transplantation, 172 of 5356 patients developed 325 non-melanoma skin cancers (excluding basal cell carcinomas) and six malignant melanomas. The relative risk of non-melanoma skin cancer was 108.6 [95% confidence interval (CI) 94.6-123.1 for men and 92.8 (95% CI 73.2-116.0) for women. The highest risks were noted for upper limbs, and the risk increased with time. No significant increase in malignant melanomas was noted: the relative risk was 1.6 (95% CI 0.5-3.7) for men and 0.5 (95% CI 0.0-2.6) for women. Except for the lip. which is also sun-exposed, other epithelial sites did not show comparable increases in cancer risk. Conclusions We conclude that organ transplant recipients are at a highly increased risk for non-melanoma skin cancer and must be closely followed throughout their lives. Cancer risk associated with transplantation is higher for sun-exposed than for non-sun-exposed epithelial tissues, even among populations living in regions with low solar insolation.
