   Sammanfattning : Neutron-carbon interactions have been studied with a focus on charged-particle production of relevance to radiation protection and medical applications, such as cancer therapy. The measurements have been performed using the particle-detection setup, MEDLEY, and the 96 MeV neutron beam at the The Svedberg Laboratory in Uppsala. LÄS MER

3. 22. Characterisation of Optical Fibers Using Dual-Comb Swept-Wavelength Interferometry

   Författare :Ekaterina Deriushkina; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; coupled-core multi-core fibers; channel modeling; swept-wavelength interferometry; characterisation measurements; transfer function; dual-comb spectroscopy;

   Sammanfattning : The growth in data traffic coupled with trends in internet use will result in a requirement for interfaces of the network to reach Tb/s data rate in the future. Considering this, novel transmission techniques that can increase the date rate with orders of magnitude must be considered. One such example is space-division multiplexing (SDM) fibers. LÄS MER

4. 23. Mathematical modeling in precision nutrition

   Författare :Viktor Skantze; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Personalized nutrition; precision nutrition; differential responders; metabotypes;

   Sammanfattning : Precision nutrition (PN) aims to tailor diets for individuals or groups based on comprehensive data to improve prevention of diseases, such as cardiometabolic diseases. Predicting individual postprandial metabolic responses and identifying individuals with similar metabolic phenotypes (metabotypes) could guide tailored diet strategies. LÄS MER

5. 24. Brood sex ratio and sex differences in Tengmalm’s owl : (Aegolius funereus)

   Författare :Tim Hipkiss; Gary Bortolotti; Umeå universitet; []
   Nyckelord :Aegolius funereus; avian CHD1 genes; brood sex ratio; differential mortality; nomadism; northern Sweden; sexual size dimorphism; sibling rivalry; supplementary feeding; vole cycles; zooekologi; Animal Ecology;

   Sammanfattning : Males and females differ in morphology and behaviour, so that selection acts differently on the two sexes. This changes the relative reproductive success of males and females, and it is beneficial for parents to bias the sex ratio of their broods in favour of the sex with the best survival and breeding prospects.

7. 25. Design and Characterization of D-band Monolithic Direct Carrier Modulator and Demodulator Circuits for High Speed Wireless Communication

   Författare :Sona Carpenter; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; modulator; MMIC; Double-Heterojunction Bipolar Transistor DHBT ; demodulator; balun; D-band; InP; Gilbert cell; Quadrature; differential coupler;

   Sammanfattning : Millimeter waves are finding increasing applications in data communication, sensing,imaging and radio astronomy. One application is in high-speed wireless back-haul networksfor mobile communication. The operators are interested in replacing optical fiber withthe more flexible and easy to deploy wireless link.
