Input-output theory of the unconventional photon blockade  [PDF]
H. Flayac,V. Savona
Physics , 2013, DOI: 10.1103/PhysRevA.88.033836
Abstract: We study the unconventional photon blockade, recently proposed for a coupled-cavity system, in presence of input and output quantum fields. Mixing of the input or output channels still allows strong photon antibunching of the output field, but for optimal values of the system parameters that differ substantially from those that maximize antibunching of the intracavity field. This result shows that the specific input-output geometry in a photonic system determines the optimal design in view of single-photon device operation. We provide a compact analytical formula that allows finding the optimal parameters for each specific system geometry.
Notions of Input to Output Stability  [PDF]
Eduardo D. Sontag,Y. Wang
Mathematics , 1999,
Abstract: This paper deals with several related notions of output stability with respect to inputs. The inputs may be thought of as disturbances; when there are no inputs, one obtains generalizations of the classical concepts of partial stability. The main notion studied is called input to output stability (IOS), and it reduces to input to state stability (ISS) when the output equals the complete state. Several variants, which formalize in different manners the transient behavior, are introduced. The main results provide a comparison among these notions. A companion paper establishes necessary and sufficient Lyapunov-theoretic characterizations.
Input-output theory for fermions in an atom cavity  [PDF]
C. P. Search,S. Poetting,W. Zhang,P. Meystre
Physics , 2002, DOI: 10.1103/PhysRevA.66.043616
Abstract: We generalize the quantum optical input-output theory developed for optical cavities to ultracold fermionic atoms confined in a trapping potential, which forms an "atom cavity". In order to account for the Pauli exclusion principle, quantum Langevin equations for all cavity modes are derived. The dissipative part of these multi-mode Langevin equations includes a coupling between cavity modes. We also derive a set of boundary conditions for the Fermi field that relate the output fields to the input fields and the field radiated by the cavity. Starting from a constant uniform current of fermions incident on one side of the cavity, we use the boundary conditions to calculate the occupation numbers and current density for the fermions that are reflected and transmitted by the cavity.

Cross-boundary, which is the key word of IT industry in 2010, swept down from upstream industries to downstream terminals, PC, software, internet… no exception in all areas. With the combination of mobile and internet, a revolutionary change has been brought about. However, the power of traditional fields can never remain mighty in new areas. By using mathematical tools form the thinking mode of discrete mathematics and continuous mathematics, the second cross-boundary is a theoretical basis of cross-boundary economic management information system as well as a scientific method for realizing the integration between the optimal input-output planning model and Big data, new technologies of Cloud Computing and Internet of Things or new internet industry. With the second cross-boundary, area, scale, strength and efficiency of its application will be beyond our imagination. Based on modernisation of enterprise management, the cross-boundary economic management information system can be used to promote not only management of enterprises, but comprehensively enhance modern management quality and governance capacity. It is not only a scientific basis for establishing “One World”, justice, mutual benefit and equal competition, it is also a method to completely eradicate the breeding ground of waste and corruption. In this paper, a brief description will be given based on real-time analysis of the optimal input-output planning model and timely analysis of input-output statistical model.
Input-output theory of Coulomb Blockade  [PDF]
Christophe Mora,Carles Altimiras,Philippe Joyez,Fabien Portier
Physics , 2015,
Abstract: We present an input-output formalism describing a tunnel junction strongly coupled to its electromagnetic environment. We exploit it in order to investigate the dynamics of the radiation being emitted and scattered by the junction. We find that the non-linearity imprinted in the electronic transport by a properly designed environment generates strongly squeezed radiation. Our results show that the interaction between a quantum conductor and electromagnetic fields can be exploited as a resource to design simple sources of non-classical radiation.

Abstract: To analyze the effect of field input on grain yield and economic benefit of farmlands, we used wheat-corn double crop-ping fields in northern Taihang Mountain Plain region of central Hebei to analyze the degree of response to input from farmland quality on basis of factor combination, hypothesis testing, regression analysis and agricultural land grade. The results suggest that grain yield can be improved by scientifically and reasonably increasing field input or using a combination of factors at low input. High yield on farmlands with poor natural conditions can be achieved through scientific and reasonable input. The optimal value of field input is within the interval between the maximum input-output benefit and maximum grain yield. Reasonably adjusted input based on differences in the influence of natural factors on grain yield and different factor combinations can increase yield significantly.
Lyapunov Characterizations of Input to Output Stability  [PDF]
Eduardo D. Sontag,Y. Wang
Mathematics , 1999,
Abstract: This paper presents necessary and sufficient characterizations of several notions of input to output stability. Similar Lyapunov characterizations have been found to play a key role in the analysis of the input to state stability property, and the results given here extend their validity to the case when the output, but not necessarily the entire internal state, is being regulated. The work is related to partial stability of differential equations (the particular case which arises when there are no external inputs).
World Input-Output Network  [PDF]

Abstract: Economic systems, traditionally analyzed as almost independent national systems, are increasingly connected on a global scale. Only recently becoming available, the World Input-Output Database (WIOD) is one of the first efforts to construct the multi-regional input-output (MRIO) tables at the global level. By viewing the world input-output system as an interdependent network where the nodes are the individual industries in different economies and the edges are the monetary goods flows between industries, we study the network properties of the so-called world input-output network (WION) and document its evolution over time. We are able to quantify not only some global network properties such as assortativity, clustering coefficient, and degree and strength distributions, but also its subgraph structure and dynamics by using community detection techniques. Over time, we detect a marked increase in cross-country connectivity of the production system, only temporarily interrupted by the 2008-2009 crisis. Moreover, we find a growing input-output regional community in Europe led by Germany and the rise of China in the global production system. Finally, we use the network-based PageRank centrality and community coreness measure to identify the key industries and economies in the WION and the results are different from the one obtained by the traditional final-demand-weighted backward linkage measure.
Decomposability in Input Output Conformance Testing

Electronic Proceedings in Theoretical Computer Science , 2013, DOI: 10.4204/eptcs.111.5
Abstract: We study the problem of deriving a specification for a third-party component, based on the specification of the system and the environment in which the component is supposed to reside. Particularly, we are interested in using component specifications for conformance testing of black-box components, using the theory of input-output conformance (ioco) testing. We propose and prove sufficient criteria for decompositionality, i.e., that components conforming to the derived specification will always compose to produce a correct system with respect to the system specification. We also study the criteria for strong decomposability, by which we can ensure that only those components conforming to the derived specification can lead to a correct system.
Input-Output Pairing for Nonlinear Multivariable Systems  [PDF]
Bijan Moaveni,Ali Khaki-Sedigh
Journal of Applied Sciences , 2007,
Abstract: Decentralized control is a well established approach to control the multivariable processes. In this approach, control structure design and in particular input-output pairing is a vital stage in the design procedure. There are several powerful methods to select the appropriate input-output pair in linear multivariable systems. However, despite the fact that most practical processes are nonlinear, there is no general method to select the appropriate input-output pair for nonlinear multivariable systems. In this study, a new general approach to input-output pairing for linear and nonlinear multivariable systems is proposed. Simulation results are employed to show the effectiveness of the proposed methodology.
