In a provocative new book, 1 George Beauchamp, MD, claims that physicians are “slaves to medicine.” He explains that this is partly because “when most people go to see a doctor, both the services the doctor provides and the fees that insurance companies allow him to charge are largely predetermined by parties other than the patients and doctors.” Most patients, in turn, feel completely powerles...

Sex determination offers an opportunity to address many classic questions of developmental biology. In addition, because sex determination evolves rapidly, it offers an opportunity to investigate the evolution of genetic hierarchies. Sex determination in Drosophila melanogaster is controlled by the master regulatory gene, Sex lethal (Sxl). DmSxl controls the alternative splicing of a downstream...

This paper summarizes the development of the synchronization control technology of the multi-motor control system. And a model structure of multi-motor synchronization control system based on the monomaster PROFIBUS-DP network is proposed, which slaves are intelligent including PLC, convertor and motor. The communication mode of MS is adopted. The control tasks of the master and their slaves ar...

Abstract In this article I explain a nexus between slavery and state formation in Africa, proceeding from initial demographic institutional conditions to an external demand shift, individual responses, their collective systemic consequences. Historically, African rulers faced distinctive challenges: low population density prioritized control of people more than territory, internal disintegratio...

The introduction of confined, “slave” fields is frequently useful as a formal device in models of condensed matter physics; it becomes a conceptual necessity for describing possible phases of matter where the slaves are liberated. Here I discuss some aspects of the fractional quantum Hall effect from this point of view, emphasizing analogies with phenomena in other areas of physics, particularl...

We develop an approach to utilize anisotropic metamaterials to solve one of the fundamental problems of modern plasmonics--parasitic scattering of surface waves into free-space modes, opening the road to truly two-dimensional plasmonic optics. We illustrate the developed formalism on the examples of plasmonic refractor and plasmonic crystal, and discuss limitations of the developed technique an...

Bluetooth is expected to be an important basic constructing component of smart homes. In a smart home environment, many devices will be portable and battery-operated, making power saving an essential issue. In this article we study the problem of managing the low-power sniff mode in Bluetooth, where a slave is allowed to be awake only periodically. One challenging problem is how to schedule eac...

Bluetooth is a universal radio interface in the 2.45Ghz frequency band, which will enable users to connect a range of small electronic devices. Any two or more Bluetooth-enabled devices that come within range of each other can set up an ad hoc connection, called a piconet. Within a piconet, the unit that establishes the piconet becomes the master and the rest of the units act as slaves. The mas...

Scholars have frequently observed that Dionysus is a god who breaks down barriers (of gender, class, social norms, et cetera). This is true in Euripides's Bacchae to a certain extent, and the play's breakdown of the divide between male/female and Greek/foreign has been well examined in scholarship. However, the limitations of this questioning of boundaries are much less discussed. For instance,...
