OGLE-2005-BLG-071Lb, the Most Massive M-Dwarf Planetary Companion?

We combine all available information to constrain the nature of OGLE-2005-BLG-071Lb, the second planet discovered by microlensing and the first in a high-magnification event. These include photometric and astrometric measurements from Hubble Space Telescope, as well as constraints from higher order effects extracted from the ground-based light curve, such as microlens parallax, planetary orbital motion and finite-source effects. Our primary analysis leads to the conclusion that the host of Jovian planet OGLE-2005-BLG-071Lb is an M dwarf in the foreground disk with mass M= 0.46 +/- 0.04 Msun, distance D_l = 3.3 +/- 0.4 kpc, and thick-disk kinematics v_LSR ~ 103 km/s. From the best-fit model, the planet has mass M_p = 3.8 +/- 0.4 M_Jup, lies at a projected separation r_perp = 3.6 +/- 0.2 AU from its host and so has an equilibrium temperature of T ~ 55 K, i.e., similar to Neptune. A degenerate model less favored by \Delta\chi^2 = 2.1 (or 2.2, depending on the sign of the impact parameter) gives similar planetary mass M_p = 3.4 +/- 0.4 M_Jup with a smaller projected separation, r_\perp = 2.1 +/- 0.1 AU, and higher equilibrium temperature T ~ 71 K. These results from the primary analysis suggest that OGLE-2005-BLG-071Lb is likely to be the most massive planet yet discovered that is hosted by an M dwarf. However, the formation of such high-mass planetary companions in the outer regions of M-dwarf planetary systems is predicted to be unlikely within the core-accretion scenario. There are a number of caveats to this primary analysis, which assumes (based on real but limited evidence) that the unlensed light coincident with the source is actually due to the lens, that is, the planetary host. However, these caveats could mostly be resolved by a single astrometric measurement a few years after the event.Comment: 51 pages, 12 figures, 3 tables, Published in Ap

High genetic diversity of measles virus, World Health Organization European region, 2005-2006

During 2005-2006, nine measles virus (MV) genotypes were identified throughout the World Health Organization European Region. All major epidemics were associated with genotypes D4, D6, and B3. Other genotypes (B2, D5, D8, D9, G2, and H1) were only found in limited numbers of cases after importation from other continents. The genetic diversity of endemic D6 strains was low; genotypes C2 and D7, circulating in Europe until recent years, were no longer identified. The transmission chains of several indigenous MV strains may thus have been interrupted by enhanced vaccination. However, multiple importations from Africa and Asia and virus introduction into highly mobile and unvaccinated communities caused a massive spread of D4 and B3 strains throughout much of the region. Thus, despite the reduction of endemic MV circulation, importation of MV from other continents caused prolonged circulation and large outbreaks after their introduction into unvaccinated and highly mobile communities

Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries

Background Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres. Methods This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries. Results In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia. Conclusion This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries

Penerapan Jaringan Saraf Tiruan untuk Menghitung Nilai Kandungan Makanan

Kasoami merupakan makanan khas tradisional dari Desa Pemana. Makanan ini berasal dari ubi kayu lalu diproses dalam pengukusan. masyarakat yang mengkonsumsi makanan tersebut kurang mengetahui adanya nilai-nilai kandungan makanan. Dengan itu di terapkannya suatu apikasi yang dinamakan Aplikasi MENIKAM. Aplikasi MENIKAM ini singkatan dari Menghitung Nilai Kandungan Makanan yang bertujuan untuk membantu masyarakat dalam mengetahui nilai kandungan makanan. Pengembangan Aplikasi MENIKAM merupakan aplikasi cerdas yang dapat membantu mengetahui nilai kandungan makanan yang dikembangkan dengan metode NIR dan Kalibrasi Jaringan Saraf Tiruan. Selain untuk menghitung nilai kandungan makanan Aplikasi MENIKAM juga dapat memberikan sebuah tutorial proses pembuatan makanan dan menyediakan salah satu form untuk penjualan makanan. Untuk hasil yang di dapatkan yaitu menentukan komposisi utama ubi kayu di ambil dua puluh sampel Ubi (biji utuh) dipindai Panjang dari 20-30 cm. Model kalibrasi untuk pengukuran NIR menggunakan Jaringan Syaraf Tiruan (JST) tiga lapisan teknik. Sebagai lapisan input JST adalah input pertama 5, kedua 10, dan 15 komponen utama (PC). Outputnya adalah komposisi simultan yang akan di prediksi. Kontribusi dari aplikasi MENIKAM ini adalah memprediksi nilai kandungan makanan yang belum masyarakat ketahui dalam mengkonsumsi dengan bantuan metode-metode yang ad

Website-Based Barberhome Service Information System (Case Study : Barbershop D'Goenting)

The modern-day technique of Barbershop D'Goenting's provider, clients nevertheless must go to the closest Barbershop without delay to get shaving offerings. Meanwhile, the hassle confronted via way of means of Barbershop D'Goenting is that it has now no longer supplied hair care offerings to clients' homes. Therefore, so as for Barbershop D'Goenting to enhance provider quality, it have to innovate. The innovation supplied via way of means of the researcher is to layout a website-primarily based totally barberhome provider statistics machine. In this observe, the fishbone evaluation approach is used to gain in-intensity purpose and impact problems, the UML layout approach is locate case diagrams, interest diagrams, series diagrams, and sophistication diagrams, in addition to the waterfall version improvement approach. The consequences of this observe layout a web-primarily based totally barberhome provider machine, specifically a call-to-domestic hair provider machine wherein clients can area orders, pick, and pick the capster as desired. The cause of this machine is designed to enhance D'Goenting's barbershop offerings in order that clients can get haircut offerings from domestic while not having to return back without delay to the barbersho

Stable, Well-Defined Nickel(0) Catalysts for Catalytic C–C and C–N Bond Formation

The synthesis and catalytic activity of several classes of NHC–Ni(0) precatalysts stabilized by electron-withdrawing alkenes are described. Variations in the structure of fumarate and acrylate ligands modulate the reactivity and stability of the NHC–Ni(0) precatalysts and lead to practical and versatile catalysts for a variety of transformations. The catalytic activity and efficiency of representative members of this class of catalysts have been evaluated in reductive couplings of aldehydes and alkynes and in <i>N</i>-arylations of amines
