"I sin debattartikel Diagnoser i vår tid: Fastlåsning och blivande, totalitet och oändlighet debatterar Mattias Nilsson Sjöberg diagnoser i vår tid utifrån exemplet med ADHD. Utgångspunkt för diskussionen tas i posthumanismen och dess möjligheter att medverka till uppluckring av kategorier. För att undgå diagnosens tendenser till totalisering och fastlåsande är det viktigt att forma en djupare för

A Δ11 desaturase from the oblique banded leaf roller moth Choristoneura rosaceana takes the saturated myristic acid and produces a mixture of (E)-11-tetradecenoate and (Z)-11-tetradecenoate with an excess of the Z isomer (35:65). A desaturase from the spotted fireworm moth Choristoneura parallela also operates on myristic acid substrate but produces almost pure (E)-11-tetradecenoate. The two desat

Aldrig i mänsklighetens historia har jordens befolkning haft det så bra som de har det nu. Världens rikedomar är större än de någonsin tidigare varit, och i takt med det ökade välståndet blir världens invånare överlag allt friskare och allt äldre. Samtidigt har de generella välfärds- och hälsoökningarna inte kommit alla till del. En person som idag föds i USA förväntas tjäna 100 gånger mer under s

This thesis addresses challenges in increasing the robustness of cloud-deployed applications and services to unexpected events and dynamic workloads. Without precautions, hardware failures and unpredictable large traffic variations can quickly degrade the performance of an application due to mismatch between provisioned resources and capacity needs. Similarly, disasters, such as power outages and

This paper investigates the potential of an infant intervention to improve life expectancy, contributing to emerging interest in the early life origins of chronic disease. We track individuals from birth to death, and are able to identify age and cause of death. The intervention was pioneered in Sweden in 1931–1933, and appears to have been pivotal in the emergence of universal infant care program

Determining structures of membrane proteins remains a significant challenge. A technique utilizing high lipid-detergent concentrations ("HiLiDe") circumvents the major bottlenecks of current membrane protein crystallization methods. During HiLiDe, the protein-lipid-detergent ratio is varied in a controlled way in order to yield initial crystal hits, which may be subsequently optimized by variation

A 2.8-to-5.8 GHz harmonic VCO designed in a 28 nm UTBB FD-SOI CMOS process adopts a reconfigurable active core to save power at the lower oscillation frequencies, and to enable a trade-off between power consumption and phase noise at all frequencies. Interference caused by the magnetic coupling to and from the VCO inductor is greatly attenuated by resorting to an inductor in the shape of an 8. Sim

A 2.8-to-5.8GHz VCO designed in a 28nm UTBB FD-SOI CMOS process adopts a reconfigurable active core to save power at the lower oscillation frequencies, and to enable a trade-off between power consumption and phase noise at all frequencies. The UTBB FD-SOI CMOS process is instrumental to achieve a tuning range in excess of one octave at low power consumption, while the use of an 8-shaped tank coil

A digital phase-locked loop (DPLL) which uses a high resolution 2-dimension gated-Vernier time-to-digital converter (TDC) is presented. The shaped Vernier quantization of TDC greatly improves the in-band phase noise. Also the 2-dimension structure makes DPLL be able to process large phase errors almost without the influence of latency time. Combined with a high figure-of-merit (FOM) class-D digita
