Several ligands based upon 2-substituted bicyclic[2.2.2]octane-2,6-diols (BODOLs) were synthesized and evaluated in two catalytic reactions: I) the Ti(IV)-mediated catecholborane asymmetric reduction of prochiral ketones and II) as catalysts in the asymmetric addition of diethylzinc to aromatic aldehydes. The ligands were prepared by baker's yeast mono-reduction of bicyclo[2.2.2]octane-2,6-dione,

This paper presents new methods trellis source coding at rates above and below one. The new schemes have in common a code design based on branch correlation, a large reproducer alphabet, and an encoder based on either the Viterbi algorithm or a tailbiting MAP technique. The methods are easily adapted to various bit rates, but here only the results for R = 2 and R = 1/2 bits per source sample are p

Prepared under the framework of the European Cluster Alliance (ECA), the report provides an overview of existing good practice examples of different tools and analytical methods used during the cluster-making process. The report is based on the results of an international survey of experts working in the field, and the outcomes of a workshop organised in Copenhagen in September 2008. A number of

The latest long-term plan for science and technology reflects China’s determination both to overcome growing domestic social and environmental problems through technology and to become a world leader in innovation. This latest fifteen-year plan presents no radical departure from earlier strategies and continues to define policymaking by Beijing’s strong belief that innovation can be “decreed” top-

Advances in scheduling theory have given designers of control systems greater flexibility over their choice of timing requirements. This could lead to systems becoming more responsive and more maintainable. However, experience has shown that engineers find it difficult to exploit these advantages due to the difficulty in determining the “real” timing requirements of systems and therefore the techn

The relationship between a reported history of trauma and dissociative symptoms has been explained in 2 conflicting ways. Pathological dissociation has been conceptualized as a response to antecedent traumatic stress and/or severe psychological adversity. Others have proposed that dissociation makes individuals prone to fantasy, thereby engendering confabulated memories of trauma. We examine data

Popular Abstract in Swedish Bakgrund Kroniskt obstruktiv lungsjukdom (KOL) är en vanlig orsak till död världen över och dödligheten ökar främst bland kvinnor. Patienter med kronisk syrebrist på grund av KOL behandlas med hemsyrgas (LTOT), men har mycket hög dödlighet. Kunskapen är idag bristfällig kring könsskillnader och tidstrender i dödlighet och dödsorsaker, betydelsen av andra sjukdomar (samsBackground Chronic obstructive pulmonary disease (COPD) is a major and rising cause of mortality worldwide, especially in women. Patients with chronic hypoxia owing to COPD are treated with long-term oxygen therapy (LTOT) but have high morbidity and mortality. Knowledge is limited on sex-related differences and time trends in mortality, effects of comorbidity on mortality and whether cardiovascula

In this paper we propose a scheme for test planning and test access mechanism (TAM) design for stacked integrated circuits (SICs) that are designed in a core-based manner. Our scheme minimizes the test cost, which is given as the weighted sum of the test time and the TAM width. The test cost is evaluated for a test flow that consists of a wafer sort test of each individual chip and a package test

The field of tissue engineering has a growing need for suitable scaffold materials to become attractive as a clinical therapy. To use a completely autologous construct to repair a damaged or diseased tissue is an appealing thought. As a model system, two types of scaffolds were prepared from biological fluids: blood and plasma. The prepared scaffolds formed a macroporous structure with elastic mec

For vehicles using grid power to charge the battery, traction circuit components are not normally engaged during the charging time, so there is a possibility to use them in the charger circuit to have an on-board integrated motor drive and battery charger. An isolated high-power three-phase integrated motor drive and charger based on a split-phase permanent magnet motor is presented in this paper.

The evaporative gas turbine (EvGT) pilot plant has been in operation at Lund University in Sweden since 1997. This project has led to improved knowledge of evaporative techniques and the concept of introducing fuel into gas turbines by evaporation. This results in, amongst others, power augmentation, efficiency increase and lower emissions. This article presents the experimental and theoretical re

We have carried out accurate, systematic calculations for the 2s2p(3 5)S(2)(o)-2s(2)2p(2 3)P(1,2) E1] lines at 1660.807 and 1666.153 Angstrom in O III. Uncertainty estimates for their A values and the lifetime of the S-5(2)o level have been determined from a set of quality criteria. A lifetime of 1.21 +/- 0.06 ms is recommended for this level, in excellent agreement with a recent experiment. The c

To assess easily monitored predictors for tuberculosis mortality. Risk factors for tuberculosis mortality were assessed during the 8-month treatment in 440 men and 269 women diagnosed with confirmed or presumed intrathoracic tuberculosis included prospectively in Guinea-Bissau from May 1996 to April 2001. A civil war occurred in the study area from June 1998 to May 1999. 12% were HIV-1 positive, 1

Empirical evaluations in software engineering are important in order to build a body of knowledge of methods that work in different environments. This thesis presents six empirical investigations of two techniques applied to software inspections, namely reading techniques and fault content estimation techniques. The first part of the thesis presents a series of experiments of a novel reading tech
