In this paper, we revisit the problem of finding the average capacity of the Gaussian feedback channel. First, we consider the problem of finding the average capacity of the analog colored Gaussian noise channel where the noise has an arbitrary spectral density. We introduce a new approach to the problem where we solve the problem over a finite number of transmissions and then consider the limi...

Abstract We argue that the effectiveness of Rwandan governments, both at implementing 1994 genocide and inducing current growth miracle, illustrates state has high capacity. Yet this capacity is not captured by conventional Weberian concepts, with their focus on taxation formal bureaucracy. Rather, Rwanda's relies its ability to leverage dense social networks which connect it society. The origi...

The paper addresses how democracy can affect public finance and state capacity investment. We show that the effect of on policy take two forms: direct indirect. transpires when increasing leads to an increase in expenditure which results increased goods provision reduced political rent. indirect emerges a reduction investment and, subsequently, provision. Paradoxically, lower rents deteriorate ...

purpose: this research seeks to determine the level of knowledge sharing, the absorptive capacity, and the innovation capability at the central libraries of the state universities of tehran in 1393. besides, it seeks to identify the relationship between knowledge sharing and innovation capability in the library. methodology: this applied research is carried out using survey method – correlation...

Information must take up space, must weigh, and its flux must be limited. Quantum limits on communication and information storage leading to these conclusions are here described. Quantum channel capacity theory is reviewed for both steady state and burst communication. An analytic approximation is given for the maximum signal information possible with occupation number signal states as a functi...

A pure-loss bosonic channel is a simple model for communication over free-space or fiberoptic links. More generally, phase-insensitive bosonic channels model other kinds of noise, such as thermalizing or amplifying processes. Recent work has established the classical capacity of all of these channels, and furthermore, it is now known that a strong converse theorem holds for the classical capaci...

A quantum channel physically is a unitary interaction between the information carrying system and an environment, which is initialized in a pure state before the interaction. Conventionally, this state, as also the parameters of the interaction, is assumed to be fixed and known to the sender and receiver. Here, following the model introduced by us earlier [Karumanchi et al., arXiv[quant-ph]:140...
