Spectral design of signal-adapted tight frames on graphs

Analysis of signals defined on complex topologies modeled by graphs is a topic of increasing interest. Signal decomposition plays a crucial role in the representation and processing of such information, in particular, to process graph signals based on notions of scale (e.g., coarse to fine). The graph spectrum is more irregular than for conventional domains; i.e., it is influenced by graph topolog

Defending Paper Gods : Aleister Crowley and the Reception of Daoism in Early Twentieth Century Esotericism

This article explores the representation of Daoism and Chinese religion in the writings of Aleister Crowley. The influence of Asian religions on the occult revival of the late nineteenth century has often been recognized. Even though much has been said about the perception of Indian religious traditions in European and American esotericism, the influence of Chinese religion on the same environment

Evolution of organ systems in the Crustacea: Mystacocarida and Cephalocrida in retrospect

The morphology of the internal organs of two representative species of the crustacean classes Mystacocarida, Derocheilocaris typica (Pennak & Zinn, 1943), and Cephalocarida, Hutchinsoniella macracantha (Sanders, 1955), has been studied ultrastructurally from 1990 onwards. A review of the subject offers a unique opportunity to compare and contrast the two taxa at a time when their key positions

Stand-Alone Artificial Intelligence for Breast Cancer Detection in Mammography : Comparison With 101 Radiologists

BACKGROUND: Artificial intelligence (AI) systems performing at radiologist-like levels in the evaluation of digital mammography (DM) would improve breast cancer screening accuracy and efficiency. We aimed to compare the stand-alone performance of an AI system to that of radiologists in detecting breast cancer in DM.METHODS: Nine multi-reader, multi-case study datasets previously used for different

Channel Correlation Diversity in MU-MIMO Systems - Analysis and Measurements

In multiuser multiple–input multiple–output (MU–MIMO) systems, channel correlation is detrimental to system performance. We demonstrate that widely used, yet overly simplified, correlation models that generate identical correlation profiles for each terminal tend to severely underestimate the system performance. In sharp contrast, more physically motivated models that capture variations in the pow

Evacuation planning optimization based on a multi-objective artificial bee colony algorithm

Evacuation is an important activity for reducing the number of casualties and amount of damage in disaster management. Evacuation planning is tackled as a spatial optimization problem. The decision-making process for evacuation involves high uncertainty, conflicting objectives, and spatial constraints. This study presents a Multi-Objective Artificial Bee Colony (MOABC) algorithm, modified to prov

Cognitive Behaviour Therapy for Post Traumatic Stress Disorder

It is only relatively recently that Post Traumatic Stress Disorder (PTSD) hasbeen recognised in children. Controlled treatment outcome studies ofchildhood PTSD are scarce, but those that exist indicate that CognitiveBehaviour Therapy (CBT) is an effective intervention. In this article, webriefly describe PTSD in children and outline some behavioural andcognitive models of the disorder. Derived fro

GAD-specific cognitive behavioral treatment for children and adolescents : A pilot randomized controlled trial

Cognitive behavioral therapy (CBT) designed to target Generalized Anxiety Disorder (GAD) in youth was examined in a pilot feasibility trial. Participants (aged 10-18 years) were randomized to either 10 weeks of individual CBT (n = 20) or supported wait-list (n = 20). Diagnostic status (primary outcome) was assessed blindly at post-treatment for both groups, and at a 3-month follow-up for treated p
