There are at least three things we might mean by “ethics in robotics”: the ethical systems built into robots, the ethics of people who design and use robots, and the ethics of how people treat robots. This paper argues that the best approach to robot ethics is one which addresses all three of these, and to do this it ought to consider robots as socio-technical systems. By so doing, it is possib...

We have calculated the Wandzura-Wilczek contribution to the twist-3 part of γ * γ → 2π amplitude. It describes interaction of the longitudinally polarized virtual photon with the real one, and it is suppressed by 1/Q, where Q 2 is the virtuality of the γ * , as compared to the twist-2 contribution. We have found that, in the Wandzura-Wilczek approximation, factorization applies to the twist-3 a...

The noisy dynamics of chemical systems is commonly studied using either the chemical master equation (CME) or the chemical Fokker-Planck equation (CFPE). The latter is a continuum approximation of the discrete CME approach. It has recently been shown that for a particular system, the CFPE captures noise-induced multistability predicted by the CME. This phenomenon involves the CME's marginal pro...

In this paper, we extend the classical Lie symmetry analysis from partial differential equations to integro-differential equations with functional derivatives. We continue the work of Oberlack and Wacławczyk (2006, Arch. Mech. 58, 597), (2013, J. Math. Phys. 54, 072901), where the extended Lie symmetry analysis is performed in the Fourier space. Here, we introduce a method to perform the extend...

For the H1 and ZEUS Collaborations Recent results of real and virtual photon structure from the H1 and ZEUS collaborations are discussed. Jet cross-sections in photoproduction processes provide new constraints on the real photon parton densities. Measurements of dijet cross-sections in deep-inelastic scattering show clear evidence for a resolved component to the virtual photon which is suppress...

On behalf of the H1 Collaboration. ABSTRACT A review of recent jet measurements of the photon structure from the H1 experiment at HERA is presented. A manifestation of the photon structure in single-jet and di-jet cross sections is shown. From di-jet cross sections the effective parton distribution function is extracted and its dependence on the scale as well as the photon virtuality is discussed.

Hyper-redundant (or snakelike) manipulators have many more degrees of freedom than are required to position and orient an object in space. They have been employed in a variety of applications ranging from search-and-rescue to minimally invasive surgical procedures, and recently they even have been proposed as solutions to problems in maintaining civil infrastructure and the repair of satellites...

Within the hard pomeron approach it is shown that the triple pomeron interaction gives no contribution to the cross-section for a projectile with large enough virtuality g 2 ln Q 2 ∼ 1. For small virtualities g 2 ln Q 2 << 1 its contribution is essential.

Continuum modeling of many physical systems typically assumes that the spatial extent of an atom is small compared to the quantities of interest and can therefore be neglected. We show that this is valid only asymptotically. For many applications of practical interest, the spatial extent of a discrete atom cannot be neglected. We have developed a model for the description of epitaxial growth ba...
