چکیده
A non-technical overview on gravity in two dimensions is provided. Applications discussed in this work comprise 2D type 0A/0B string theory, Black Hole evaporation/thermodynamics, toy models for quantum gravity, for numerical General Relativity in the context of critical collapse and for solid state analogues of Black Holes. Mathematical relations to integrable models, non-linear gauge theories, Poisson-sigma models, KdV surfaces and non-commutative geometry are presented.

Knowledge in lineland
In this paper we investigate a concrete epistemic situation: there are agents (humans, robots, cameras,...) and propositions (lamps on or off, obstacles dangerous or not,...) located in Lineland. We express properties with the standard epistemic logic language like “Agent A knows that agent B knows that lamp L is on”. We give some words about modelchecking, satisfiability problem and common kno...
متن کاملIntrahepatic ramifications of the portal vein in the horse
The ramifications of the portal vein in the liver of horses were studied by using corrosion casting and gross dissection. The portal vein in the horse supplies the hepatic lobes by six major branches. The right lobe is supplied by three main branches, namely the dorsal diaphragmatic, the right caudodorsal and the right intermediate branches. The left branch supplies the left lateral and medial ...
متن کاملEpistemic reasoning in Lineland
In this paper we investigate a concrete situation of epistemic spatial reasoning: there are agents (humans, cameras,...) which are located on a line, and according to their respective positions and to where agents are looking at, the epistemic situation will vary. Using standard epistemic logic language, we aim at expressing various properties (“Agent A knows that agent B sees agent C”,...) For...
متن کاملAbility of Three Endodontic Sealers to Fill the Root Canal System in Association with Gutta-Percha
INTRODUCTION The present study compared the ability of the endodontic sealers AH Plus, Pulp Canal Sealer and EndoREZ to fill the root canal system in association with gutta-percha. METHODS Ninety mandibular premolars were accessed, prepared and divided into three groups of 30 teeth each, according to the sealer used to fill the canals: AH Plus, Pulp Canal Sealer and EndoREZ. All the teeth wer...
متن کاملNegative Labeling as a Crucial Psychological Variable in Teaching EFL Learners
One of the psychological variables which may have a long-lasting effect on our life is labeling, and students’ accomplishments might be severely undermined through the teacher’s labeling. In spite of this issue, few studies have been carried out on the ramifications of labeling in the educational contexts, in general, and EFL classrooms, in particular. The current study is an attempt to investi...
