In Diagonally Non-Computable Functions and Bi-Immunity [2], Carl Jockusch and Andrew Lewis-Pye proved that every DNC function computes a bi-immune set. They asked whether every DNC function computes an effectively bi-immune set. We construct a DNC function that computes no effectively bi-immune set, thereby answering their question in the negative.

We show that every non-low c.e. set joins all ∆2 diagonally noncomputable functions to ∅′. We give two proofs: a direct argument, and a proof using an analysis of functions that are DNC relative to an oracle, extending work by Day and Reimann. The latter proof is also presented in the language of Kolmogorov complexity.

D annual expenditures on public relations exceeding $19.42 billion, U.S. businesses lack practical guidance about the effectiveness of publicity in mass media. Here, we assemble a rich and novel data set to gauge the impact of news reports on consumer sign-ups with the U.S. Do Not Call (DNC) Registry. Using multiple identification strategies, we found robust evidence that news reports increased...

typical production objectives in distillation process require the delivery of products whose compositions meet certain specifications. the distillation control system, therefore, must hold product compositions as near the set points as possible in faces of upset. in this project, inferential model predictive control, that utilizes an artificial neural network estimator and model predictive cont...

This paper considers stabilization and command following of uncertain dynamical systems and presents a new adaptive control approach with improved system performance. The proposed framework consists of a novel architecture involving modification terms in the adaptive controller and the update law. Specifically, these terms are activated when the system error between an uncertain dynamical syste...

− The paper focuses on the control problem of a tentacle robot that performs the coil function of the grasping. First, the dynamic model of a tentacle arm with continuum elements produced by flexible composite materials in conjunction with activecontrollable electro-rheological fluids is analyzed. Secondly, both problems, i.e. the position control and the force control are approached. The diffi...
