Characterizing the physical channel and calibrating the cryptosystem hardware are prerequisites for establishing a quantum channel for quantum key distribution (QKD). Moreover, an inappropriately implemented calibration routine can open a fatal security loophole. We propose and experimentally demonstrate a method to induce a large temporal detector efficiency mismatch in a commercial QKD system...

A careful analysis of the teacher-student relationship at any level, inside or outside the school, reveals its fundamentally narrative character. This relationship involves a narrating Subject (the teacher) and patient, listening objects (the students). The contents, whether values or empirical dimensions of reality, tend in the process of being narrated to become lifeless and petrified. Educat...

In this paper we define agreement in terms of shared public commitments, and implicit agreement is conditioned on the semantics of the relational speech acts (e.g., Narration, Explanation) that each agent performs. We provide a consistent interpretation of disputes, and updating a logical form with the current utterance always involves extending it and not revising it, even if the current utter...

In his article "Borges's Postmodern Landscape" Mario Vrbančić examines specific constructs of space -among them heterotopia (Michel Foucault) and hyperreality (Jean Baudrillard) -and applies them to narration and narrative strategies in Jorge Luis Borges's texts. Vrbančić posits that postmodern mapping undermines our known familiar geography and that authors like Borges who experimented with di...

In this paper, we try to bridge the gap between different dimensions/incarnations of mathematical knowledge: MKM representation formats (content), their human-oriented languages (source, presentation), their narrative linearizations (narration), and relational presentations used in the semantic web. The central idea is to transport solutions from software engineering to MKM regarding the parall...

We present a novel interaction technique that helps to make printed information more accessible to those with low or no textual literacy skills. AudioCanvas allows cameraphone users to interact directly with their own photos of media items to receive audio feedback or narration on demand.
