A Theory of Reciprocity [PDF]

open access: yesGames and Economic Behavior, 2000
This paper presents a formal theory of reciprocity. Reciprocity means that people reward kind actions and punish unkind ones. The theory takes into account that people evaluate the kindness of an action not only by its consequences but also by the intention underlying this action.

Revisión de desobturación de gutapercha con limas manuales, Xilol y Reciproc [PDF]

open access: yes, 2018
El tratamiento endodóntico no quirúrgico es de primera elección en el caso de fracasos endodónticos. El primer paso del retratamiento es la desobturación del conducto radicular, que va a permitir la preparación biomecánica del conducto radicular con ...

Comparative Evaluation of Three Different Obturating Techniques Lateral Compaction, Thermafil and Calamus for Filling Area and Voids Using Cone Beam Computed Tomography: An Invitro study [PDF]

open access: yesJournal of Clinical and Diagnostic Research, 2015
Introduction: The success of root canal treatment depends upon the proper sealing of root canal system. Improper apical seal leads to the microleakage which can be prevented by proper obturation technique.

Reciprocity and Anti-Reciprocity Revisited [PDF]

open access: yesIEEE Antennas and Propagation Magazine, 2010
Using a general definition for reciprocity and anti-reciprocity, the validity conditions of popular definitions and results have been examined and clarified for lumped, linear, time-invariant n-ports. With this definition based purely on input-output characteristics, some new criteria are obtained with no additional assumptions, such as the n-port ...
