Atherosclerosis as a disease is postulated to stem from a response to injury of the arterial wall by various stimuli. The inflammatory response is proposed to mediate intimal formation after injury. One pathway of cellular response to injury is through transcription factor NF-kB. We show that balloon injury of rat arteries leads to increased NF-kB activity and ICAM-1 expression, associated with i
The (dynamic) frame model, originating in artificial intelligence and cognitive psychology, has recently been applied to change-phenomena traditionally studied within history and philosophy of science. Its application purpose is to account for episodes of conceptual dynamics in the empirical sciences (allegedly) suggestive of incommensurability as evidenced by “ruptures” in the symbolic forms of h

Problemområdet arbetsrelaterad stress har inte någon entydig ämnesteoretisk hemvist eller definition. Trots områdets vaga konturer måste forskare, praktiker och lekmän ofta förhålla sig till arbetsrelaterad stress. Exempelvis är diskussionen om stress och stressrelaterade tillstånd vanligt förekommande i medierna, bland politiker och hos allmänheten. Det är dock ovanligt att sjukdomar som misstänk
Abstract—Background: History based regression testing was proposed as a basis for automating regression test selection, for the purpose of improving transparency and test efficiency, at the function test level in a large scale software development organization. Aim: The study aims at investigating the current manual regression testing process as well as adopting, implementing and evaluating the ef
We consider whether stellar collisions can explain the observed depletion of red giants in the Galactic center. We model the stellar population with two different IMFs: 1) the Miller-Scalo and 2) a much flatter IMF. In the former case, low-mass main-sequence stars dominate the population, and collisions are unable to remove red giants out to 0.4 pc although brighter red giants much closer in may b
The blade tip region encounters high thermal loads because of the hot gas leakage flows, and it must therefore be cooled to ensure a long durability and safe operation. A common way to cool a blade tip is to design serpentine passages with 180-deg turn under the blade tip-cap inside the turbine blade. Improved internal convective cooling is therefore required to increase the blade tip lifetime. Di
I "Hotad idyll" förenas litteraturvetenskapens intressen för texter med historievetenskapens intresse för bredare sammanhang för att nå en större förståelse av historiska skeenden. I fokus står de föreställningar som präglade den vardagliga idyllen i 1950- och 1960-talens Sverige.
This paper presents a hardware mapping of an auto-correlator for Orthogonal Frequency Division Multiplexing stage for three radio standards: LTE, DVB-H, and IEEE 802.11n. Hardware cost is minimized by using only the sign bit in the autocorrelation function. The frequency offset estimation procedure is dramatically simplified by reducing the phase of the envelope to pi/2 resolution, which in turn r
