The search for the onset of star formation in pre-stellar cores has focussed on the identification of an infall signature in the molecular line profiles of tracer species. The classic infall signature is a double peaked line profile with an asymmetry in the strength of the peaks such that the blue peak is stronger. L1689B is a pre-stellar core and infall candidate but new JCMT HCO + line profil...

Abstract A large part of the explainable AI literature focuses on what explanations are in general, algorithmic explainability is more specifically, and how to code these principles into systems. Much less attention has been devoted question why decisions systems should be whether there ought a right explanation why. We therefore explore normative landscape need for individuals having such expl...

The socio-economic status of people with permanent disabilities in Bulgaria and the policies for their labour integration as part social inclusion were studied. Based on comparisons data from two representative empirical sociological surveys, an evaluation was made changes profile this group persons that occurred period 2009-2020 (demographic variables such age, gender place residence; educatio...

Small conical-shaped jets may emanate from a liquid bath short while after small drop has hit pool. Here we perform Particle Image Velocimetry (PIV) measurements of the flow inside upward impact and show that fluid elements decelerate up to 5-20 times gravitational acceleration. The both shape jet velocity profile are self-similar. A theoretical model including surface tension, inertia, gravity...

Neutrophil gelatinase-associated lipocalin (NGAL) is a novel 25-kD protein of human neutrophils, that is in part covalently complexed with neutrophil gelatinase. However, both NGAL and gelatinase exist mainly in forms not associated with each other. An explanation for this phenomenon might be that the unassociated proteins reside in different subcellular compartments. The aim of the present stu...

Comparative analysis of the roles of explanation and meta explanation is conducted assessing the validity of explanation exchanged between human agents. Meta explanation links the overall structure of a current scenario with that of previously learned scenarios of multi agent interaction. The scenario structure includes communicative actions of involved agents and argumentation attack relations...

A great deal of research has demonstrated that learning is influenced by the learner’s prior background knowledge (e.g. Murphy, 2002; Keil, 1990), but little is known about the processes by which prior knowledge is deployed. We explore the role of explanation in deploying prior knowledge by examining the joint effects of eliciting explanations and providing prior knowledge in a task where each ...

In this second part of our study on the mechanism of perceived brightness, we explore the effects of manipulating three-dimensional geometry. The additional scenes portrayed here demonstrate that the same luminance profile can elicit different sensations of brightness as a function of how the objects in the scene are arranged in space. This further evidence confirms the implication of the scene...
