Ultraviolet C II and Si III Transit Spectroscopy and Modeling of the Evaporating Atmosphere of GJ436b
Hydrogen gas evaporating from the atmosphere of the hot-Neptune GJ436b
absorbs over 50% of the stellar Ly emission during transit. Given the
planet's atmospheric composition and energy-limited escape rate, this hydrogen
outflow is expected to entrain heavier atoms such as C and O. We searched for C
and Si in the escaping atmosphere of GJ436b using far-ultraviolet HST COS G130M
observations made during the planet's extended H I transit. These observations
show no transit absorption in the C II 1334,1335 \AA\ and Si III 1206 \AA\
lines integrated over [-100, 100] km s, imposing 95% (2) upper
limits of 14% (C II) and 60% (Si III) depth on the transit of an opaque disk
and 22% (C II) and 49% (Si III) depth on an extended, highly asymmetric transit
similar to that of H I Ly. C is likely present in the outflow
according to a simulation we carried out using a spherically-symmetric,
photochemical-hydrodynamical model. This simulation predicts a 2% transit
over the integrated bandpass, consistent with the data. At line center, we
predict the C II transit depth to be as high as 19%. Our model predicts a
neutral hydrogen escape rate of g s (
g s for all species) for an upper atmosphere composed of hydrogen and
helium.Comment: 7 pages, 4 figures, 1 table; accepted to ApJ Letter

Low temperatures impact species distributions of jumping spiders across a desert elevational cline.
Temperature is known to influence many aspects of organisms and is frequently linked to geographical species distributions. Despite the importance of a broad understanding of an animal's thermal biology, few studies incorporate more than one metric of thermal biology. Here we examined an elevational assemblage of Habronattus jumping spiders to measure different aspects of their thermal biology including thermal limits (CTmin, CTmax), thermal preference, V̇CO2 as proxy for metabolic rate, locomotor behavior and warming tolerance. We used these data to test whether thermal biology helped explain how species were distributed across elevation. Habronattus had high CTmax values, which did not differ among species across the elevational gradient. The highest-elevation species had a lower CTmin than any other species. All species had a strong thermal preference around 37 °C. With respect to performance, one of the middle elevation species was significantly less temperature-sensitive in metabolic rate. Differences between species with respect to locomotion (jump distance) were likely driven by differences in mass, with no differences in thermal performance across elevation. We suggest that Habronattus distributions follow Brett's rule, a rule that predicts more geographical variation in cold tolerance than heat. Additionally, we suggest that physiological tolerances interact with biotic factors, particularly those related to courtship and mate choice to influence species distributions. Habronattus also had very high warming tolerance values (> 20 °C, on average). Taken together, these data suggest that Habronattus are resilient in the face of climate-change related shifts in temperature
Analisis Kinerja Pendapatan Asli Daerah Dikaitkan dengan Belanja Daerah pada Pemerintah Kota Bitung
Pendapatan Asli Daerah adalah pendapatan yang dianggarkan dalam APBD meliputi semua penerimaan uang melalui kas umum daerah, yang menambah ekuitas dana, yang merupakan hak daerah dalam satu tahun anggaran yang tidak perlu dibayar kembali oleh daerah. Kinerja adalah gambaran pencapaian pelaksanaan suatu kegiatan/program/kebijakan dalam mewujudkan sasaran, misi, tujuan dan visi organisasi.Tujuan penelitian ini untuk menganalisis kinerja keuangan Pendapatan Asli Daerah (PAD) pada pemerintah Kota Bitung yang diukur menggunakan analisis rasio keuangan tahun anggaran 2006-2010.Metode analisis yang digunakan adalah metode deskriptif dengan menggunakan analisis rasio, antara lain, (1) Rasio Kemandirian Keuangan Daerah, (2) Rasio Efektifitas, (3) Rasio Keserasian, (4) Rasio Pertumbuhan. Hasil penelitian, dapat disimpulkan bahwa kinerja pemerintah Kota Bitung dalam khususnya pada PAD dilihat dari tingkat kemandirian masih rendah dan memiliki kecenderungan menurun. Jika dilihat dari keefektifan, secara umum dapat dikatakan sangat efektif karena dari tahun 20062010 rata-rata efektivitas Pendapatan Asli Daerah yaitu 102,38%. Dilihat dari tingkat keserasian, secara umum belum serasi karena kinerja Pendapatan Asli Daerah pada belanja tidak langsung lebih besar daripada belanja langsung. Dan jika dilihat dari tingkat pertumbuhan, secara umum efektiv karena dari tahun 20062010 rata-rata pertumbuhan sebesar 95,70%. Kata kunci: kinerja, rasio, ekuitas dana
Transport optimization on complex networks
We present a comparative study of the application of a recently introduced
heuristic algorithm to the optimization of transport on three major types of
complex networks. The algorithm balances network traffic iteratively by
minimizing the maximum node betweenness with as little path lengthening as
possible. We show that by using this optimal routing, a network can sustain
significantly higher traffic without jamming than in the case of shortest path
routing. A formula is proved that allows quick computation of the average
number of hops along the path and of the average travel times once the
betweennesses of the nodes are computed. Using this formula, we show that
routing optimization preserves the small-world character exhibited by networks
under shortest path routing, and that it significantly reduces the average
travel time on congested networks with only a negligible increase in the
average travel time at low loads. Finally, we study the correlation between the
weights of the links in the case of optimal routing and the betweennesses of
the nodes connected by them.Comment: 19 pages, 7 figure
Conformal anomaly from gauge fields without gauge fixing
We show how the Weyl anomaly generated by gauge fields, can be computed from
manifestly gauge invariant and diffeomorphism invariant exact renormalization
group equations, without having to fix the gauge at any stage. Regularisation
is provided by covariant higher derivatives and by embedding the Maxwell field
into a spontaneously broken supergauge theory. We first provide a
realisation that leaves behind two versions of the original gauge field,
and then construct a manifestly supergauge invariant flow equation
which leaves behind only the original Maxwell field in the spontaneously broken
regime.Comment: 24 page
exo-10,11-Dibromotricyclo[6.3.1.02,7]dodeca-2,4,6,9-tetraene
The title compound, C12H10Br2, is a bridged ring system based on a homobenzonorbornadiene framework. The exo configuration of one of the Br atoms was previously assigned via NMR correlations and has now been confirmed by the geometry of the solid-state structure. The compound features a Br—C—C—Br torsion angle of 66.68 (12)°, whereby the C atoms in the calculation are respectively sp

Equity valuation of Under Armour
A dissertação aqui apresentada tem como objetivo apresentar uma avaliação para a Under Armour, - empresa que desenvolve a sua atividade na indústria do equipamento desportivo.
A Under Armour representa um exemplo de empreendedorismo, determinação e excelência, personalizada pelo seu fundador e atual diretor executivo. Kevin Plank criou a empresa em 1996, com apenas 23 anos, através do desenvolvimento de um protótipo de uma t-shirt desportiva. Entretanto, a empresa já experienciou uma OPA em 2005 e tem revelado um crescimento exponencial e consistente em termos de receitas, tendo conseguido expandir as suas operações a um nível global.
Três modelos diferentes de avaliação foram usados nesta dissertação, com o objetivo de encontrar um intervalo de valores, no qual o valor intrínseco das ações da Under Armour se encontrarão. A avaliação realizada foi ainda comparada com uma outra avaliação externa, desenvolvida por uma empresa especializada na área da avaliação financeira – The Buckingham Research Group. Pretendeu-se, assim, possibilitar uma perspetiva mais alargada ao leitor, quer quanto aos métodos usados na avaliação, quer quanto aos seus resultados.
Concluídos todos estes procedimentos, de acordo com a metodologia explanada, foi feita uma nota de investimento, com a recomendação de Buy e um preço-alvo de 37 per share for the Class A common stock
