Intuitively, obedience – following the order that a human gives – seems like a good property for a robot to have. But, we humans are not perfect and we may give orders that are not best aligned to our preferences. We show that when a human is not perfectly rational then a robot that tries to infer and act according to the human’s underlying preferences can always perform better than a robot tha...

zled by such abandonment, but literature suggests that there are many different ways of dealing with pain and suffering. Modern physicians learn to look mainly at disease, defined as whatever can be detected ("imaged") by our machinery, scanner, endoscope, or chemical analyzer. Too few learn to pay attention to illness, the patient's experiencebecause illness cannot be visualized and is hard to...

For generic squark masses, box diagrams with squarks and gluinos give unacceptably large contributions to neutral meson (K, B and D) mixing. The standard solution to this problem is to assume that squarks are degenerate to a very good approximation. We suggest an alternative mechanism to suppress squark contributions to flavor changing neutral currents: the alignment of quark with squark mass m...

Abstract-The elastoplastic constitutive analysis which utilizes the model of multiplicative decomposition of the defo~ation gradient into its elastic and plastic parts has been mainly developed and applied to elastically isotropic materials, which remain isotropic during the process of plastic deformation. This paper extends the application of the model to materials that change their elastic pr...

Extant research has typically relied on the use of political knowledge items or interviewer evaluations to measure the political sophistication of survey respondents. In this paper, I further develop Luskin’s approach to measuring sophistication using knowledge items, items based on recognition and understanding of ideological terms, and items based on correct candidate and party placements on ...

Twitter needs no introduction. This "microblogging" service has gained tremendous popularity in the 2 years since its launch. Yet, most scientists are steering clear of it. Laura Bonetta speaks to some who have found value in tweeting.

A 23-year-old man was referred to the emergency room with complaints of dyspnoea and dizziness followed by rapid palpitations. He had no relevant medical history and was not using any medication. The family history was negative for arrhythmias and sudden death. Physical examination revealed a tachycardia of 160 beats/min with a normal blood pressure; also, a frog sign was visible. Initial labor...
