We present an independent discovery and detailed characterization of K2-280 b, a transiting low density warm sub-Saturn in a 19.9-d moderately eccentric orbit (e = 0.35 -0.04+0.05) from K2 campaign 7. A joint analysis of high precision HARPS, HARPS-N, and FIES radial velocity measurements and K2 photometric data indicates that K2-280 b has a radius of Rb = 7.50 ± 0.44 R⊕ and a mass of Mb = 37.1 ±
A significant fraction of an exoplanet transit model evaluation time is spent calculating projected distances between the planet and its host star. This is a relatively fast operation for a circular orbit, but slower for an eccentric one. However, because the planet's position and its time derivatives are constant for any specific point in orbital phase, the projected distance can be calculated ra
Childhood poverty increases the likelihood of being poor as an adult. We know relatively little about this persistence of poverty in the past and whether it changed as modern welfare societies developed. This study both analyses determinants of childhood poverty and assesses the association between childhood poverty and economic outcomes in adulthood for men and women who grew up in southern Swede
We report the discovery of a planetary system orbiting TOI-763(aka CD-39 7945), a V = 10.2, high proper motion G-type dwarf star that was photometrically monitored by the TESS space mission in Sector 10. We obtain and model the stellar spectrum and find an object slightly smaller than the Sun, and somewhat older, but with a similar metallicity. Two planet candidates were found in the light curve t
A method to evaluate and recondition lungs ex vivo has been tested on donor lungs that have been rejected for transplantation. In the present paper, we compare early postoperative course between the six patients who received reconditioned lungs and the patients who received conventional donor lungs during the same period of time. During 2006 and 2007, a total of 21 patients underwent double sequen
Background: A moderate elevation of plasma total homocysteine (tHcy) is considered a potential risk factor for Alzheimer's disease (AD). Methods: We have investigated the main determinants (age, renal impairment, cobalamin/folate status and the presence of vascular disease) of plasma tHcy in 326 patients with AD, and also in 281 patients with mild cognitive impairment (MCI), since about half of th
In the method of exterior complex scaling the coordinates of the Hamilton operator are scaled by a constant factor starting at a radius R≠0. We show that this procedure induces a singularity in the kinetic-energy term which must be interpreted as the derivative of a δ function.
Arm lymphedema is a well-known side effect of breast cancer treatment. Studies of the effect of physical exercise on arm lymphedema are very rare. The purpose of this study was to investigate the influence of pole walking on breast cancer-related arm lymphedema when using a compression sleeve. Twenty-six women with unilateral arm lymphedema took part in a clinical study of pole walking on one occa
Purpose We investigated whether active video gaming (AVG) could bring about regular, enjoyable, physical exercise in children treated for brain tumours, what level of physical activity could be reached and if the children's physical functioning improved. Methods Thirteen children, aged 7-17 years, were randomised to either AVG or waiting-list. After 10-12 weeks they crossed-over. Weekly Internet c
Well-differentiated hepatocellular carcinoma (HCC) may resemble benign liver lesions on initial diagnostic work-up. The validity of surgical resection for preoperatively unclear liver lesions was investigated in this study.
Objective: Primary hyperparathyroidism (PHPT) is associated with cardiovascular morbidity and premature death but the underlying mechanisms are incompletely understood. The aim of this study was to investigate if adrenergic dysfunction may be a contributing factor. Patients and methods: Forty-nine patients with mild PHPT (serum calcium 2.7 ± 0.1 mmol/L) and 48 control subjects, matched for age an
We report on a forward RNAi screen in primary human hematopoietic stem and progenitor cells, using pooled lentiviral shRNA libraries deconvoluted by next generation sequencing. We identify MAPK14/p38α as a modulator of ex vivo stem cell proliferation and show that pharmacological inhibition of p38 dramatically enhances the stem cell activity of cultured umbilical cord blood derived hematopoietic c
More knowledge concerning the association between physical activity and objectively measured attributes of the built environment is needed. Previous studies on the association between objectively measured neighborhood walkability, physical activity, and walking have been conducted in the U.S. or Australia and research findings are available from only one country in Europe - Belgium. The first aim
