We describe a state recovery attack on the X-FCSR-256 stream cipher of total complexity at most $2^{57.6}$. This complexity is achievable by requiring $2^{49.3}$ output blocks with an amortized calculation effort of at most $2^{8.3}$ table lookups per output block using no more than $2^{33}$ table entries of precomputational storage.

This paper discusses some cultural considerations that we stand before in developing and exploiting an agent based educational software for use by Swedish and American students, age 11-14. The reported cultural challenges arise in software develop¬ment, study designs, and decisions on actual pedagogical use in the two cultural settings.

I denna artikel behandlas konstruktionen av prästerlig manlighet bland katolska församlingspräster i Norden i slutet av 1800-talet och under 1900-talets första årtionden. Flera av dessa präster var nordiska konvertiter. Detta innebar att de inkulturerats i en protestantisk kulturmiljö, vilken de sedan lämnat till förmån för den katolska gemenskapen. Det prästmannaideal som präglade det samhälle de

Popular Abstract in Swedish Bröstcancer är den vanligaste cancerformen hos västerländska kvinnor. I Sverige kommer var tionde kvinna att drabbas av bröstcancer, vilket motsvarar drygt 5000 kvinnor om året. Dödligheten i bröstcancer är 30%. Detta innebär att en tredjedel av de som drabbas kommer att dö av sin sjukdom. Det är dock inte själva tumören i bröstet som dödar eftersom denna i princip alltBreast cancer is one of the most common cancer forms in the industrialized world. Only in Sweden, nearly 6000 women are diagnosed with breast cancer each year and 1/3 of them eventually succumb to the disease. Wnts are a family of genes that have been implicated in many human tumours, so far mainly studied in colorectal cancer where activated Wnt signalling occurs in a vast majority of tumours. Wh

The emittances of the electron beams at the MAX-laboratory accelerator system have been studied. Apart from the build-up of the diagnostic tools for precise determination of the beam spatial profiles, the objectives have been: a) to verify the accelerator design emittances at low currents and to try to determine the emittances also at high currents; b) to investigate possibilities to manipulate th

This study aims to: (1) identify some of the active and latent conditions that allow maritime security incidents to occur, and (2) explore the feasibility of adapting the Rasmussen-Svedung AcciMap as a tool for maritime security management. These twin objectives are pursued by applying concepts and principles, propounded by Rasmussen and Svedung, to a case study of the 1999 hijacking of the Alondr

A receiver front-end supporting contiguous and non-contiguous intra-band carrier aggregation scenarios with a fully integrated spectrum sensor that can detect both in-gap and out-of-band blockers has been implemented in 65nm CMOS technology. An NF of 2.5dB is achieved using a noise canceling LNTA, and linearized OTAs are used to achieve an IIP3 improvement of up to 6.5dB in-band and 11dB at the fi
