Three Small Planets Transiting a Hyades Star

We present the discovery of three small planets transiting K2-136 (LP 358 348, EPIC 247589423), a late K dwarf in the Hyades. The planets have orbital periods of 7.9757 ± 0.0011, 17.30681-0.00036+0.00034, and 25.5715-0.0040+0.0038 days, and radii of 1.05 ± 0.16, 3.14 ± 0.36, and 1.55-0.21+0.24 R⊕, respectively. With an age of 600-800 Myr, these planets are some of the smallest and youngest transit

K2-137 b : An Earth-sized planet in a 4.3-h orbit around an M-dwarf

We report the discovery in K2's Campaign 10 of a transiting terrestrial planet in an ultrashort- period orbit around an M3-dwarf. K2-137 b completes an orbit in only 4.3 h, the second shortest orbital period of any known planet, just 4 min longer than that of KOI 1843.03, which also orbits an M-dwarf. Using a combination of archival images, adaptive optics imaging, radial velocity measurements, an

Proteomic analysis of brain metastatic lung adenocarcinoma reveals intertumoral heterogeneity and specific alterations associated with the timing of brain metastases

Background: Brain metastases are associated with considerable negative effects on patients’ outcome in lung adenocarcinoma (LADC). Here, we investigated the proteomic landscape of primary LADCs and their corresponding brain metastases. Materials and methods: Proteomic profiling was conducted on 20 surgically resected primary and brain metastatic LADC samples via label-free shotgun proteomics. Afte

The discovery and mass measurement of a new ultra-short-period Planet : K2-131b

We report the discovery of a new ultra-short-period planet and summarize the properties of all such planets for which the mass and radius have been measured. The new planet, K2-131b, was discovered in K2 Campaign 10. It has a radius of and orbits a G dwarf with a period of 8.9 hr. Radial velocities obtained with Magellan/PFS and TNG/HARPS-N show evidence for stellar activity along with orbital mot

Three Super-Earths Transiting the Nearby Star GJ 9827

We report on the discovery of three transiting planets around GJ 9827. The planets have radii of 1.75±0.18, 1.36±0.14, and 2.11 0.21 0.22 - + R⊕, and periods of 1.20896, 3.6480, and 6.2014 days, respectively. The detection was made in Campaign 12 observations as part of our K2 survey of nearby stars. GJ 9827 is a V = 10.39 mag K6V star at a distance of 30.3±1.6 parsecs and the nearest star to be f

K2-106, a system containing a metal-rich planet and a planet of lower density

Aims. Planets in the mass range from 2 to 15 M⊙ are very diverse. Some of them have low densities, while others are very dense. By measuring the masses and radii, the mean densities, structure, and composition of the planets are constrained. These parameters also give us important information about their formation and evolution, and about possible processes for atmospheric loss. Methods. We determ

The Transiting Multi-planet System HD 3167 : A 5.7 M Super-Earth and an 8.3 M Mini-Neptune

HD 3167 is a bright (V = 8.9 mag) K0 V star observed by NASA's K2 space mission during its Campaign 8. It has recently been found to host two small transiting planets, namely, HD 3167b, an ultra-short-period (0.96 days) super-Earth, and HD 3167c, a mini-Neptune on a relatively long-period orbit (29.85 days). Here we present an intensive radial velocity (RV) follow-up of HD 3167 performed with the

Mass determination of K2-19b and K2-19c from radial velocities and transit timing variations

We present radial velocity follow-up observations of K2-19, a compact planetary system hosting three planets, of which the two larger ones, K2-19b and K2-19c, are close to the 3:2 mean motion resonance. An analysis considering only the radial velocity measurements detects K2-19b, the larger and more massive planet in the system, with a mass of 54.8 ± 7.5M⊕ and provides a marginal detection of K2-1

Muskulär pseudo­hypertrofi yttrade sig som mjukdels­tumör - Denervering av tensor fasciae latae visade sig vara orsaken

Pseudohypertrophy of musculus tensor fascia lata presenting as a soft tissue tumor: a case report Conditions presenting as palpable soft tissue masses are a common clinical issue. This case report describes a patient with unilateral pseudohypertrophy of m. tensor fasciae latae, which is an uncommon differential diagnosis for a palpable soft tissue mass. The patient presented a palpable soft tissue

Flicker : a technological overview

Flicker can be annoying, but above all it can have a negative effect on human health; causing irritation, headaches, eye strain and migraines. With the introduction of LED lamps, flicker has once again become a problem. In addition to the unnecessary suffering caused to individuals, the negative consequences create an obstacle to the wide and rapid adoption of new LED technology and thus also an oFlicker can be annoying, but above all it can have a negative effect on human health; causing irritation, headaches, eye strain and migraines.

Flimmer – en teknisk översikt

Flimmer kan vara irriterande, men framför allt kan det ha en negativ effekt på människors hälsa, orsaka irritation, huvudvärk, ögonansträngning och migrän. I och med införandet av LED-lampor har flimmer åter blivit ett problem. Förutom det onödiga lidande flimmer orsakar hos individer, skapar de negativa konsekvenserna ett hinder för bred och snabb anpassning av den nya LED-tekniken och därmed ock

Use of data mining and artificial intelligence to derive public health evidence from large datasets

This thesis explores the use of data mining and AI-tailored frameworks for extracting public health evidence from large health datasets. The research presented in this thesis demonstrates the potential of these tools for automating and simplifying the data mining process, and for providing valuable insights into various public health issues.In Paper I, we used data mining and natural language proc

Community adaptation to temperature explains abrupt soil bacterial community shift along a geothermal gradient on Iceland

Understanding how and why soil microbial communities respond to temperature changes is important for understanding the drivers of microbial distribution and abundance. Studying soil microbe responses to warming is often made difficult by concurrent warming effects on soil and vegetation and by a limited number of warming levels preventing the detection of non-linear effects. A unique area in Icela

Temperature dependent intercalation of molten 1-hexadecanol into Brodie graphite oxide

Intercalation of very long molecules into the structure of multi-layered graphene oxide (GO) was studied using example of 1-hexadecanol (C16), an alcohol molecule with 16 carbon atoms. Brodie graphite oxide (BGO) immersed in excess of liquid C16 just above the melting point shows expansion of c-unit cell parameter from ∼6 Å to ∼48.76 Å forming a structure with two densely packed layers of C16 mole

Molecular dynamics simulations of nanometric cutting of single crystal copper sheets using a diamond tool

Nanometric cutting of a single crystal copper workpiece of different crystallographic orientations by a stiff cylindrical cubic diamond tool has been investigated by MD simulations using the freeware LAMMPS. The chip evolves during the cutting process and forms depending on crystal orientation, cutting velocity and tool geometry. It was found that no significant difference in the cutting force mag

'It depends on who I'm with' : How young people with developmental language disorder describe their experiences of language and communication in school

BACKGROUND: The risks of developmental language disorder (DLD) for both educational progress and socio-emotional development are well documented, but little is known about how children and young people with DLD experience and describe their language and communication. The need to complement experimental and quantitative studies with qualitative perspectives of the lived experience of individuals w
