Digital to analog conversion apparatus [PDF]
, 1973 A digital to analog converter which improves the accuracy of reconstruction of a sampled analog signal without requiring that the sampling rate of the original signal be increased to obtain such ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT End‐of‐life conversations with adolescents and young adults (AYAs) with cancer rarely occur without the guidance of healthcare professionals. As a part of the ‘Difficult Discussions’ study, focused on palliative care and advance care planning discussions with AYAs with cancer, we investigated the factors that healthcare professionals identify ...

Spectral approach to determination of Kotelynikov's theorem application conditions
Известия высших учебных заведений России: Радиоэлектроника, 2015 Kotelynikov’s theorem application details are discussed for the case of signals with finite spectrum, when spectrum density at the high-frequency cutoff is nonzero.

Signal and System Approximation from General Measurements
, 2014 In this paper we analyze the behavior of system approximation processes for stable linear time-invariant (LTI) systems and signals in the Paley-Wiener space PW_\pi^1.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Purpose Pediatric central nervous system (CNS) tumors often recur despite multimodality therapy. Although re‐irradiation (re‐RT) has historically been limited by concerns for severe late toxicities, modern techniques have renewed interest in this approach. Proton therapy provides dosimetric advantages that may enable curative re‐treatment with

Features of signal sampling and reconstruction in nonlinear systems
Известия высших учебных заведений. Поволжский регион:Технические наукиBackground. Digital signal processing involves sampling continuous signals. Unlike linear systems, performing this operation in nonlinear systems has a number of features associated with expanding the spectrum of the output signal.

Defining Roles in Pediatric Palliative Care: Perspectives From Oncology and Palliative Care Teams
Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Early integration of pediatric palliative care (PPC) is associated with improved symptom management, quality of life, and healthcare utilization for children with cancer. Despite this, variation persists in how PPC is understood, operationalized, and integrated within pediatric oncology programs. In particular, ambiguity surrounding

A Probabilistic Interpretation of Sampling Theory of Graph Signals
, 2015 We give a probabilistic interpretation of sampling theory of graph signals. To do this, we first define a generative model for the data using a pairwise Gaussian random field (GRF) which depends on the graph.
