Traffic-Aware Channel Sensing Order in Dynamic Spectrum Access Networks
"... Abstract—In this paper we present new results on the problem of finding the best channel sensing order for multi-channel Dynamic Spectrum Access (DSA) networks. We start with the general assumption that all Secondary Users (SUs) cooperatively sense each Primary User (PU) channel at one time. Then, t ..."

on the DSA network throughput by computing a new metric called sensing order confidence, i.e., the probability that the best selected sensing order is not affected by PU traffic estimation errors. Finally, we formulate a convex optimization problem to determine the minimum number of PU channel state samples
Coil sensitivity encoding for fast MRI. In:
- Proceedings of the ISMRM 6th Annual Meeting,
, 1998
"... New theoretical and practical concepts are presented for considerably enhancing the performance of magnetic resonance imaging (MRI) by means of arrays of multiple receiver coils. Sensitivity encoding (SENSE) is based on the fact that receiver sensitivity generally has an encoding effect complementa ..."

to channel and there is noise correlation between samples taken simultaneously, i.e., there are non-zero cross-terms. Second, unlike a matrix representation of FFT, a SENSE reconstruction matrix generally is not unitary. As a consequence, unlike standard Fourier images the noise level in a SENSE image varies
Color plane interpolation using alternating projections
- IEEE Trans. Image Processing
, 2002
"... Abstract—Most commercial digital cameras use color filter arrays to sample red, green, and blue colors according to a specific pattern. At the location of each pixel only one color sample is taken, and the values of the other colors must be interpolated using neighboring samples. This color plane in ..."

Simulation-based computation of information rates for channels with memory
- IEEE TRANS. INFORM. THEORY
, 2006
"... The information rate of finite-state source/channel models can be accurately estimated by sampling both a long channel input sequence and the corresponding channel output sequence, followed by a forward sum–product recursion on the joint source/channel trellis. This method is extended to compute up ..."

Finite State Channels with Time-Invariant Deterministic Feedback
"... We consider capacity of discrete-time channels with feedback for the general case where the feedback is a time-invariant deterministic function of the output samples. Under the assumption that the channel states take values in a finite alphabet, we find a sequence of achievable rates and a sequence ..."

Continuity and discontinuity of behavioral inhibition and exuberance: Psychophysiological and behavioral influences across the first four years of life.
- Child Development,
, 2001
"... Abstract: Four-month-old infants were screened (N = 433) for temperamental patterns thought to predict behavioral inhibition, including motor reactivity and the expression of negative affect. Those selected (N = 153) were assessed at multiple age points across the first 4 years of life for behavior ..."

to specific affective states, Fox and his colleagues have found relations between EEG asymmetry and shyness in adults and reticence in children. Specifically, adults who rated themselves as high in shyness displayed right frontal EEG asymmetry The following study reports on two cohorts of infants, some
Is cash negative debt? A hedging perspective on corporate financial policies, London Business School IFA Working Paper Series
, 2004
"... We model the interplay between cash and debt policies in the presence of financial constraints. While saving cash allows financially constrained firms to hedge against future income shortfalls, reducing debt – “saving borrowing capacity ” – is a more effective way of securing future investment in h ..."

in high cash flow states. This trade-off implies that constrained firms will allocate excess cash flows into cash holdings if their hedging needs are high (i.e., if the correlation between operating cash flows and investment opportunities is low). However, constrained firms will use excess cash flows
Experimental Limit to Interstellar 244 Pu Abundance
, 2001
"... Short-lived nuclides, now extinct in the solar system, are expected to be present in interstellar matter (ISM). Grains of ISM origin were recently discovered in the inner solar system and at Earth orbit and may accrete onto Earth after ablation in the atmosphere. A favorable matrix for detection of ..."

of the sample shows no excess over the expected stratospheric nuclear fallout content and under reasonable assumptions sets a limit of 0.2 244 Pu atoms/cm 2 yr for extra-terrestrial deposition. Using available data on ISM steady-state flux on Earth, we derive a limit of 2 × 10−11 g-244Pu/g-ISM for the abundance
