Creating Humans – Ethics of Scientific Progress: Frankenstein and Heart of a Dog
Technical progress has often led us to ethical considerations, including the situations when technical development can go too far. Literature has long taken the deepest interest in natural sciences, at some points with reference to recent or future inventions, sometimes by far extending the technical possibilities of their time. One of the most popular technical mind plays has been the creation of the artificial human, the so called homunculus - both in science and literature. This work looks at Mary Shelley's Frankenstein and Michail Bulgakov's Heart of a Dog in terms of how each of them, respectively, reflects ethical concerns connected to the process of making a man, questioning motivation and responsibility of the scientist, and consequences for both a creator and a creature. Two literary examples are both mystical and alchemical elements, as well as the inclusion of actual natural science practices. Clear ethical concerns are expressed in both examples, and at different levels. Scientist are individuals who are eager to make scientific progress, transcend their competences and therefore, have to reckon dramatic interventions in the life. The main failure is a lack of responsibility for the creature they create
Realisation of educational subject "Professional English language" in terms of international initiative CDIO
The abstract considers the Worldwide CDIO Initiative, its standards and plans. The purposes and tasks of "Professional English Language" are analyzed to determine its correlation with the standards and plans of CDIO. The interdisciplinary connection of "Professional English Language" and "Electronics" is shown. Teaching methods applicable for practical lessons of "Professional English Language" for the 4th year students of Electronics and Automation of Nuclear Power Plants Department are pointed out. The work is urgent as Tomsk Polytechnic University joined the Project and can be useful and recommended for Professional English Language teachers interested in the topic

Two-resonator circuit QED: Dissipative Theory
We present a theoretical treatment for the dissipative two-resonator circuit
quantum electrodynamics setup referred to as quantum switch. There, switchable
coupling between two superconducting resonators is mediated by a
superconducting qubit operating in the dispersive regime, where the qubit
transition frequency is far detuned from those of the resonators. We derive an
effective Hamiltonian for the quantum switch beyond the rotating wave
approximation and study the dissipative dynamics within a Bloch-Redfield
quantum master equation approach. We derive analytically how the qubit affects
the quantum switch even if the qubit has no dynamics, and we estimate the
strength of this influence. The analytical results are corroborated by
numerical calculations, where coherent oscillations between the resonators, the
decay of coherent and Fock states, and the decay of resonator-resonator
entanglement are studied. Finally, we suggest an experimental protocol for
extracting the damping constants of qubit and resonators by measuring the
quadratures of the resonator fields.Comment: 17 pages, 9 figure
Tunable coupling engineering between superconducting resonators: from sidebands to effective gauge fields
In this work we show that a tunable coupling between microwave resonators can
be engineered by means of simple Josephson junctions circuits, such as dc- and
rf-SQUIDs. We show that by controlling the time dependence of the coupling it
is possible to switch on and off and modulate the cross-talk, boost the
interaction towards the ultrastrong regime, as well as to engineer red and blue
sideband couplings, nonlinear photon hopping and classical gauge fields. We
discuss how these dynamically tunable superconducting circuits enable key
applications in the fields of all optical quantum computing, continuous
variable quantum information and quantum simulation - all within the reach of
state of the art in circuit-QED experiments.Comment: 11 pages, 4 figure
Mechanical frequency control in inductively coupled electromechanical systems
Nano-electromechanical systems implement the opto-mechanical interaction
combining electromagnetic circuits and mechanical elements. We investigate an
inductively coupled nano-electromechanical system, where a superconducting
quantum interference device (SQUID) realizes the coupling. We show that the
resonance frequency of the mechanically compliant string embedded into the
SQUID loop can be controlled in two different ways: (i) the bias magnetic flux
applied perpendicular to the SQUID loop, (ii) the magnitude of the in-plane
bias magnetic field contributing to the nano-electromechanical coupling. These
findings are quantitatively explained by the inductive interaction contributing
to the effective spring constant of the mechanical resonator. In addition, we
observe a residual field dependent shift of the mechanical resonance frequency,
which we attribute to the finite flux pinning of vortices trapped in the
magnetic field biased nanostring.Comment: 5 pages, 3 figure
