Displacement-covariant time-frequency energy distributions [PDF]
1995 International Conference on Acoustics, Speech, and Signal Processing, 2002 Important classes of quadratic time-frequency representations (QTFRs), such as Cohen's (1966) class and the affine, hyperbolic, and power classes, are special cases within a general theory of displacement-covariant QTFRs. We present a theory of quadratic time-frequency energy distributions that satisfy a covariance property and generalized marginal ...

Clinical Insights Into Hypercalcemia of Malignancy in Childhood
Pediatric Blood &Cancer, EarlyView.ABSTRACT Hypercalcemia of malignancy (HCM) is a rare but life‐threatening metabolic emergency in children that occurs in less than 1% of pediatric cancer cases, with a reported incidence ranging from 0.4% to 1.0% across different studies. While it is observed in 10%–20% of adult malignancies, pediatric HCM remains relatively uncommon.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Purpose Retinoblastoma (RB) is the most common pediatric ocular cancer, yet population‐based data on survival and risk factors remain limited. This study aimed to describe survival in a large national RB cohort and identify predictors of death and complications.

Comparison of techniques for estimating the frequency selectivity of bandlimited channels [PDF]
, 2000 A transmission channel used in application such as telecommunications can be modeled as a bandpass filter. Measurement of the frequency selectivity of the channel is important to ensure that the information-bearing signal has minimal distortion and loss ...

Concepts for the Temporal Characterization of Short Optical Pulses
EURASIP Journal on Advances in Signal Processing, 2005 Methods for the characterization of the time-dependent electric field of short optical pulses are reviewed. The representation of these pulses in terms of correlation functions and time-frequency distributions is discussed, and the strategies for their ...
