We constrain the densities of Earth-to Neptune-size planets around very cool (T-e = 3660-4660 K) Kepler stars by comparing 1202 Keck/HIRES radial velocity measurements of 150 nearby stars to a model based on Kepler candidate planet radii and a power-law mass-radius relation. Our analysis is based on the presumption that the planet populations around the two sets of stars are the same. The model ca
We present results from stopped beam rare isotope spectroscopic investigations at the GSI (RISING) experiment based on the detection of gamma-ray transitions following the beta decay of Pd-94. A comparison between the measured low-lying level scheme of Rh-94 and the prediction from shell-model calculations reveals the important roles of the g(7/2) and g(9/2) orbitals in explaining the structural f
The streaming instability is a promising mechanism to overcome the barriers in direct dust growth and lead to the formation of planetesimals. Most previous studies of the streaming instability, however, were focused on a local region of a protoplanetary disk with a limited simulation domain such that only one filamentary concentration of solids has been observed. The characteristic separation betw
Målet med vår forskning är att utveckla nya behandlingsformer för barn med svårbehandlad epilepsi. Epilepsi är en av våra vanligaste neurologiska sjukdomar och karakteriseras av återkommande krampanfall. 60 miljoner människor världen över lider av epilepsi och det kan drabba vem som helst. Dock är risken högst bland barn och äldre. Idag finns inget botemedel mot epilepsi. De behandlingsformer s
According to the principle of least action, the spatially periodic motions of one-dimensional mechanical systems with no external forces are described in the Lagrangian formalism by geodesics on a manifold-configuration space, the group D of smooth orientation-preserving diffeomorphisms of the circle. The periodic inviscid Burgers equation is the geodesic equation on D with the L-2 right-invariant
Three different commercially available polymeric films were studied to determine their effect on the sensory properties of fresh broccoli (Brassica oleracea L. var. Italica cv. ‘Marathon’). The polymer materials investigated were oriented polypropylene (OPP), polyvinyl chloride (PVC) and one low density polyethylene (LDPE) which contained an ethylene absorber. The fresh broccoli was packaged and s
The increased possibilities for geographical separation of the production process have given rise to a growing interest for trade in intermediate goods in the international trade literature. Thanks to trade in parts and components, but also in services and other immaterial products, developing countries have been able to enter the global trade scene to a greater extent than before. This paper anal
While discussing the possibility of investigating the polysemy of an English profanity as the topic for this essay, Dylan Glynn, who is supervising this work, pointed to an (albeit old) edition of an Oxford English Dictionary resting on a shelf in his office in order to look up the definition[s] of the lexeme fuck. However, the entry was nowhere to be found, and this only added to the interest of
Recently, uropathogenic Escherichia coli were shown to express a virulence factor that specifically inhibits Toll-like receptor (TLR) signaling. The TIR-domain protein C (TcpC), has high homology with the TIR (Toll Interleukin Receptor) domains of innate immune signaling molecules such as TLR4, TRIF, TRAM and MyD88. By binding to these domains, TcpC prevents TIR homodimerization and inhibits innat
Granitic rocks are durable materials sought after for the production of road and railroad aggregates. Granitic bedrock commonly, however, includes gabbroic components, which may enhance or decrease the aggregate performance. This study evaluates the variation in resistance to fragmentation (Los Angeles value, LA) and wear/abrasion (micro-Deval value, MDE) for the fraction 10/14 mm of gabbro in dif
In this study, we apply a combination of methods for understanding how business models need to change to meet changing business conditions in the future (time horizon 2050). The process of applying the value proposition canvas and the business model canvas for understanding the future business models to the case of district heating has been documented. The energy transition necessitates a combinat
We discuss the Empirical Bayes approach to the problem of multiple testing and compare it with a very popular frequentist method of Benjamini and Hochberg aimed at controlling the false discovery rate. Our main focus is the 'sparse mixture' case, when only a small proportion of tested hypotheses is expected to be false. The specific parametric model we consider is motivated by the application to d
Objective: Cardiovascular disease can be prevented through lifestyle changes, but such changes are often hard to attain. Text message interventions with lifestyle advice have shown small but promising effects. Our objective was to explore participant experience of a text message lifestyle intervention for patients with hypertension, and implications for future lifestyle interventions. Design and s
The lead arrangers of syndicated loans often have lending relationships with the borrowers, while other lenders participating in the syndicate largely engage in an arm’s length transaction. Relatively little is known about how these relationships affect the shares of syndicated loans that the lead arrangers retain in their portfolio. Using a random sample of 10,328 syndicated loans made to 7316 no
The gender patenting gap is well-established and is wide. Despite important progress made over the past decades, the gap remains. Why are women underrepresented in patenting activities? What are the roots of the gender patenting gap? How did the gap evolve since the ‘modern’ patenting system was established? Our knowledge of women’s contribution to innovative activities in the past is extremely sc
We characterize the common range of the adjoints of cyclic multiplication operators on the Drury-Arveson space. We show that a function belongs to this common range if and only if its Taylor coefficients satisfy a simple decay condition. To achieve this, we introduce the uniform Smirnov class on the ball and determine its dual space. We show that the dual space of the uniform Smirnov class equals
In the second episode of the second season Nic and Rebecca invite Diane Feuillet to the microphone. Diane is a researcher here at Lund Observatory working on galactic archaeology using stellar abundances, ages and kinematics. In this second season of the Meridian we are also bringing you some field reporting from the Nordic Optical Telescope on La Palma, where a team of astronomers are trying to
