We propose a cost-effective digital coherent scheme with low-complexity signal processing (DSP) for short-reach optical interconnection. Differential 8-ary quadrature amplitude modulation (D8QAM) 1-decision-aided adaptive differential decoding bypasses carrier recovery and enables cycle-slip-free operation. experimentally demonstrate that the receiver sensitivity of 400-Gb/s D8QAM is insensitiv...

A subjective survey on perceived environmental quality has been carried out on 51 secondary-school classrooms, some of which have been acoustically renovated, and acoustical measurements were carried out in eight of the 51 classrooms, these eight being representative of the different types of classrooms that are the subject of the survey. A questionnaire, which included items on overall quality...

In the far future of an accelerating ΛCDM cosmology, the cosmic web of largescale structure consists of a set of increasingly isolated halos in dynamical equilibrium. We examine the approach of collisionless dark matter to hydrostatic equilibrium using a large N-body simulation evolved to scale factor a = 100, well beyond the vacuum– matter equality epoch, aeq = 0.75, and 53h −1 Gyr into the fu...

BACKGROUND Expectancies such as memories, motivations and emotions towards alcohol are an important predictor of alcohol consumption in the population. The Alcohol Expectancy Questionnaire (AEQ-III) can measure objectively these expectancies. AIM To study which expectancies are associated to alcohol consumption in adults living in Bucaramanga, Colombia. MATERIAL AND METHODS The AEQ-III was ...

AIMS University student alcohol misuse is a considerable problem. Alcohol expectancy research has contributed significantly to our understanding of problem drinking in young adults. Most of this research has investigated positive expectancy alone. The current study utilized two measures of alcohol expectancy, the alcohol expectancy questionnaire (AEQ) and the drinking expectancy profile [consis...

BACKGROUND Alcohol consumption is associated to expectancies of global positive behavioral changes, improvement in sexual performance and a higher level assertiveness. These issues are evaluated by the Alcohol Expectancy Questionnaire (AEQ-III). AIM To perform a factorial validation of the Alcohol Expectancy Questionnaire (AEQ-III). MATERIALS AND METHODS The questionnaire was applied to a r...

The superfamily of EF-hand proteins is comprised of a large and diverse group of proteins that contain one or more characteristic EF-hand calcium-binding domains. This study describes and characterizes a novel EF-hand cDNA, CnidEF, from the sea anemone Anthopleura elegantissima (Phylum Cnidaria, Class Anthozoa). CnidEF was found to contain two EF-hand motifs near the C-terminus of the deduced a...
