Experimental Observation of the Quantum Anomalous Hall Effect in a Magnetic Topological Insulator [PDF]

Science, 2013
Quantized and Anomalous The Hall effect, an electromagnetic phenomenon with a straightforward explanation, has many exotic counterparts, including a quantized version occurring independently of the presence of external magnetic fields.

Responses of wild titi monkeys, Callicebus coimbrai (Primates: Platyrrhini: Pitheciidae), to the habituation process

Zoologia (Curitiba), 2010
Adequate habituation of free-ranging subjects is essential for any field study, but is generally unsystematic. Here, attempts to habituate three titi monkey (Callicebus coimbrai Kobayashi & Langguth, 1999) groups are described, and factors determining ...

Direct Observation of Josephson Capacitance [PDF]

, 2005
The effective capacitance has been measured in the split Cooper pair box (CPB) over its phase-gate bias plane. Our low-frequency reactive measurement scheme allows to probe purely the capacitive susceptibility due to the CPB band structure.

From blast wave to observation [PDF]

, 2009
Gamma-ray burst (GRB) afterglows are well described by synchrotron emission originating from the interaction between a relativistic blast wave and the external medium surrounding the GRB progenitor.

Observation of Bose-Einstein Condensation in a Strong Synthetic Magnetic Field [PDF]

, 2015
Extensions of Berry's phase and the quantum Hall effect have led to the discovery of new states of matter with topological properties. Traditionally, this has been achieved using gauge fields created by magnetic fields or spin orbit interactions which ...

Observation of a continuous time crystal [PDF]

Science, 2022
Time crystals are classified as discrete or continuous depending on whether they spontaneously break discrete or continuous time translation symmetry.

Behavioral Cloning from Observation [PDF]

International Joint Conference on Artificial Intelligence, 2018
Humans often learn how to perform tasks via imitation: they observe others perform a task, and then very quickly infer the appropriate actions to take based on their observations.

Existential anthropology: what could it be? An interpretation of Heidegger [PDF]

Argument, 2014
Based on an interpretation of the work of Martin Heidegger, this article offers a shift away from social and cultural anthropology, which explores sociocultural aspects, and also from general anthropology, which aims to summarise all dimensions of human ...

Does Observation Create Reality? [PDF]

, 2020
It has been suggested that the locality of information transfer in quantum entanglement indicates that reality is subjective, meaning that there is an innate inseparability between the physical system and the conscious mind of the observer.
