- We present electrically injected GaAs/GaAsBi single quantum well laser diodes (LDs) emitting at a record long wavelength of 1141 nm at room temperature grown by molecular beam epitaxy. The LDs have excellent device performances with internal quantum efficiency of 86%, internal loss of 10 cm-1 and transparency current density of 196 A/cm2. The LDs can operate under continuous-wave mode up to 273 K. The characteristic temperature are extracted to be 125 K in the temperature range of 77?150 K, and reduced to 90 K in the range of 150?273 K. The temperature coefficient of 0.3 nm/K is extracted in the temperature range of 77?273 K.

- Rheumatoid arthritis (RA) is a highly heritable complex disease with unknown etiology. Multi-ancestry genetic research of RA promises to improve power to detect genetic signals, fine-mapping resolution and performances of polygenic risk scores (PRS). Here, we present a large-scale genome-wide association study (GWAS) of RA, which includes 276,020 samples from five ancestral groups. We conducted a multi-ancestry meta-analysis and identified 124 loci (P < 5 × 10−8), of which 34 are novel. Candidate genes at the novel loci suggest essential roles of the immune system (for example, TNIP2 and TNFRSF11A) and joint tissues (for example, WISP1) in RA etiology. Multi-ancestry fine-mapping identified putatively causal variants with biological insights (for example, LEF1). Moreover, PRS based on multi-ancestry GWAS outperformed PRS based on single-ancestry GWAS and had comparable performance between populations of European and East Asian ancestries. Our study provides several insights into the etiology of RA and improves the genetic predictability of RA.

Konferensbidrag (refereegranskat)abstract
- With the advent of wearable devices equipped with publicly visible screens, we argue for the need to apply fashion thinking in designing their visual expression. The screen provides endless variations of visual expression, beyond traditional clothing. The topic motivates us to investigate the potential of assembling “fashion thinking” with services generation, to create new forms of use that wearers will adore, as they do with clothes. Disregarding fashion thinking in wearable design might lead to user dissatisfaction and missed opportunities. In an explorative design study we triangulate three methods i.e. a small study on the use of smart watches in dressing practices; an invention and design of a service called “Watch for Figuracy”, with a watch face contextually dependent on the wearer’s dressed ensemble, and finally an initial user feedback study. Altogether they indicate the potential of fashion wearable hybrids and shortcomings in utilizing color theory for matching the watch face to the outfit.
