In this paper we present a new, heuristic method for computing logarithms over GF(2P). When 2P-1 is a Mersenne prime <231-1 it works in very short running times on a general purpose computer. It is based on the interdependent relations f,~(t) = t-2~f(t) 2" and log f~s(t) = - 2' + 2" log f(t), where f and frs are polynomials over GF(2). Its cryptographic significance is discussed and it can be cons
Abstract Background. The impact of cancer on spouses of cancer patients may be considerable in many aspects. Our objective was to evaluate sick leave in spouses of cancer patients before and after the diagnosis. Material and methods. Using Swedish population-based registries, we studied sick leave of spouses to patients with newly diagnosed colon, rectal, lung, prostate, or breast cancer. We ident
This overview aims to give an indication of the current status and trends in occupational health epidemiology in the Nordic countries. As indicated by recent biometric reviews, Nordic countries currently rank among the top five globally in terms of research output on the work environment. However, birth-cohort effects and rapid change in institutions and funding may seriously jeopardize this posit
A test equipment for the measurement of material properties within a damage zone subject to combined tension and shear deformations is described. Some results have been presented and discussed concerning the damage zone behaviour under such conditions
A unified approach to search for and optimize codes determined by their sparse parity-check matrices is presented. Replacing the nonzero elements of a binary parity-check matrix (the base or parent matrix) either by circulants or by companion matrices of elements from a finite field GF(2m), we obtain quasi-cyclic low-density parity-check (LDPC) block codes and binary images of nonbinary LDPC block
Maniq, spoken by 250-300 people in southern Thailand, is an undocumented geographical outlier of the Aslian branch of Austroasiatic. Isolated from other Aslian varieties and exposed only to Southern Thai, this northernmost member of the group has long experienced a contact situation which is unique in the Aslian context. Aslian is otherwise mostly under influence from Malay, and exhibits typologic
The aim was to study dentists' judgement on the removal of and on the development of pathology associated with asymptomatic mandibular third molars. Thirty general dental practitioners (GDPs) and 10 oral surgeons were asked to judge 36 molars with equal distribution of three cues: patient's age, angular position and degree of impaction of the molar. Rating on a VAS was found to be an appropriate m
Since listeners usually look at the speaker's face, gestural information has to be absorbed through peripheral visual perception. In the literature, it has been suggested that listeners look at gestures under certain circumstances: 1) when the articulation of the gesture is peripheral; 2) when the speech channel is insufficient for comprehension; and 3) when the speaker him- or herself indicates t

To investigate the molecular deficiency in MMR genes associated to Lynch syndrome.
BACKGROUND:: In 2006, a new genetic variant of Chlamydia trachomatis (nvCT) was discovered in Sweden. Clinical manifestations of this infection were studied in a high-risk population. METHODS:: During 2007, a prospective case-control study on sexual lifestyle and urogenital infections was performed at the Centre for Sexual Health (CSH), affiliated to Malmo University Hospital. A total of 629 C. tr
The use of test-coverage measures (e.g., block-coverage to control the software test process has become an increasingly common practice. This is justified by the assumption that higher test-coverage helps achieve higher defect-coverage and therefore improves software quality. In practice, data often show that defect-coverage and test-coverage grow over time, as additional testing is performed. How
