2. 1. Inferring Evolutionary Processes of Humans

   Author : Sen Li; Mattias Jakobsson; Ludovic Orlando; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Approximate Bayesian Computation; TMRCA; demography; human evolution; Bantu-Expansion; Out-of-Africa;

   Abstract : More and more human genomic data has become available in recent years by the improvement of DNA sequencing technologies. These data provide abundant genetic variation information which is an important resource to help us to understand the evolutionary history of humans. READ MORE

4. 2. Factors of impotance for women's health at midlife with special emphasis on effect by sex steroids

   Author : Cairu Li; Kardiovaskulär forskning - epidemiologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; andrologi; reproduktion; reproduction; sexuality; Obstetrik; gynekologi; sexualitet; andrology; gynaecology; Obstetrics; lipids; carbohydrate metabolism; norethisterone acetate; estradiol; HRT; symptomatology; Menopause; midlife women;

   Abstract : Menopause is not a disease, but may bring about a wide range of health complaints and increase some risks of illnesses. The aim of this study was to evaluate the general health status and influences of background factors on symptomatology among a cohort of Swedish women aged 50-64 years, with specific emphasis on the effects of hormone replacement therapy (HRT) by investigating a profile of HRT use, long-term effects of HRT by different tapes and routes of administration as well as clinical and metabolic changes by use of low dose HRT.

6. 4. Lignin- and PAN-based carbon fibres as negative electrodes for alkali-ion batteries

   Author : Kevin Peuvot; Göran Lindbergh; Dan Zenkert; Enn Lust; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hard carbon; lithium-ion batteries; sodium-ion batteries; potassium-ion batteries; lignin-based carbon fibres; PAN-based carbon fibres; free-standing electrodes; Chemical Engineering; Kemiteknik;

   Abstract : The development of sodium-ion batteries (SIBs) and potassium-ion batteries (KIBs) have accelerated since they can now reach similar gravimetric energy densities as lithium-ion batteries (LIBs) but with a lower environmental impact. Hard carbon is the most common negative electrode for SIBs and KIBs and can be made from renewable resources such as lignin. READ MORE

7. 5. On Landmark Densities in Minimum-Uncertainty Motion Planning

   Author : Jonas Nordlöf; Daniel Axehill; Gustaf Hendeby; Patric Jensfelt; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Accurate self-positioning of autonomous mobile platforms is important when performing tasks such as target tracking, reconnaissance and resupply missions. Without access to an existing positioning infrastructure, such as Global Navigation Satellite Systems (GNSS), the platform instead needs to rely on its own sensors to obtain an accurate position estimate.
