Kolevská J . , V. Bruncl ík , M. Svoboda: Circadian Rhythm of Cortisol Secretion in Dogs of Different Daily Activities. Acta Vet. Brno 2003, 72: 599-605. The concentrations of immunoreactive cortisol were monitored over 24 hours in the serum of a total of 23 dogs. The dogs were divided into three groups: (a) control group with no exercise, (b) experimental group, (c) working dogs. Blood was col...

This paper studies second-order coding rates for memoryless channels with a state sequence known non-causally at the encoder. In the case of finite alphabets, an achievability result is obtained using constant-composition random coding, and by using a small fraction of the block to transmit the type of the state sequence. For error probabilities less than 1 2 , it is shown that the second-order...

This paper presents an achievable second-order coding rate for the discrete memoryless Gel’fand-Pinkser channel. The result is obtained using constant-composition random coding, and by using an asymptotically negligible fraction of the block to transmit the type of the state sequence.

In this work, we propose a new construction of polar lattices to achieve the rate-distortion bound memoryless Gaussian source. The structure proposed allows integrate entropy coding into lattice quantizer, which greatly simplifies compression process. overall complexity encoding and decoding is O(N log <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink...

We study an analog of the well-known Gel’fand Pinsker Channel which uses quantum states for the transmission of the data. We consider the case where both the sender’s inputs to the channel and the channel states are to be taken from a finite set (cq-channel with state information at the sender). We distinguish between causal and non-causal channel state information at the sender. The receiver r...

In this paper, we discuss the Stochastic Resonance (SR) effect for the binary-input ternary-output (2,3) Discrete Memoryless Channels (DMC). The (2,3) DMC is of great interest for various digital communications channels, including acoustic underwater communication. We focus on the capacity maximization, brought about by additive Gaussian noise, for the (2,3) DMCs. We analyze the capacity of the...

We unify f -divergences, Bregman divergences, surrogate loss bounds (regret bounds), proper scoring rules, matching losses, cost curves, ROC-curves and information. We do this by systematically studying integral and variational representations of these objects and in so doing identify their primitives which all are related to cost-sensitive binary classification. As well as clarifying relations...

In this work, we derive achievable rate regions for the three-user interference channels with asymmetric transmitter cooperation and various decoding capabilities at the receivers. The three-user channel facilitates different ways of message sharing between the transmitters. We introduce two natural ways of extending the concept of unidirectional message sharing from two users to three users (i...

In this paper we provide an achievable rate region for the discrete memoryless multiple access channel with correlated state information known non-causally at the encoders using a random binning technique. This result is a generalization of the random binning technique used by Gel’fand and Pinsker for the problem with non-causal channel state information at the encoder in point to point communi...

This is a literal copy of a manuscript from 1974. References have been updated. It contains a critical discussion of in those days recent concepts of “common information” and suggests also alternative definitions. (Compare pages 402–405 in the book by I. Csiszár, J. Körner “Information Theory: Coding Theorems for Discrete Memoryless Systems”, Akademiai Kiado, Budapest 1981.) One of our definiti...
