OBJECTIVE To determine whether foster children showed different autonomic nervous system activity on separation and reunion than control children. Autonomic nervous system activity in foster children was examined in relation to time in placement and disinhibited attachment. METHOD The sample included 60 foster and 50 control children between 2 and 7 years of age who participated with their ca...

The comminution of spent lithium-ion batteries (LIBs) produces a powder containing the active cell components, commonly referred to as “black mass.” Recently, froth flotation has been proposed treat fine fraction black mass (<100 µm) method separate anodic graphite particles from cathodic lithium metal oxides (LMOs). So far, pyrolysis considered an effective treatment remove organic binders ...

The objective of this work is to create an automatic clustering procedure that produces results consistent with manual clustering of data points by humans. First, we developed a clustering technique using an M-ART (Mahalanobis distance-based Adaptive Resonance Theory) neural network. The “vigilance” parameter ρ in the M-ART network affects the maximum size of clusters, and consequently affects ...

Objectives: The ventriloquism effect is the tendency to underestimate the spatial separation between synchronous auditory and visual signals moderately separated in space. If, as it is thought, this effect is pre-attentive, it could modulate the mismatch negativity (MMN) that indexes the automatic, pre-attentive detection of deviant auditory stimuli rarely occurring in a sequence of standard st...

Managing information systems (IS) professionals in American industry has been making headlines as technology-intensive businesses search for ways to cope with an ever-changing economic landscape. Consequently, understanding and predicting the impact of workforce-related policy and interventions that can influence employee behavior is crucial. This paper introduces three constructs aimed at refi...

We discuss Klein's, Winnicott's, and Mahler's object relational theories relevant for creating and maintaining the mature love relationship. The concept of love refers to the basic human relationship. The capacity for adult love involves the attainment of the relation towards the object as whole, satisfying the emotional needs of the self, including simultaneous tolerance of the specific needs ...

Determination of selenium in biological and environmental samples is usually difficult due to its trace or ultra-trace quantities, pre-concentration stages, destruction of organic matrices by acid digestion and oxygen plasma combustion followed by separation from interfering metal ions such as ion exchange separation, solvent extraction or hydride generation. Selective separation of selenium is...

We newly propose a stable algorithm for blind source separation (BSS) combining multistage ICA (MSICA) and linear prediction. The MSICA is the method previously proposed by the authors, in which frequency-domain ICA (FDICA) for a rough separation is followed by time-domain ICA (TDICA) to remove residual crosstalk. For temporally correlated signals, we must use TDICA with a nonholonomic constrai...

Cochannel speech separation aims to separate two speech signals from a single mixture. In a supervised scenario, the identities of two speakers are given, and current methods use pre-trained speaker models for separation. One issue in model-based methods is the mismatch between training and test signal levels. We propose an iterative algorithm to adapt speaker models to match the signal levels ...

Model-based approaches to achieve Single Channel Source Separation (SCSS) have been reasonably successful at separating two sources. However, most of the currently used model-based approaches require pre-trained speaker specific models in order to perform the separation. Often, insufficient or no prior training data may be available to develop such speaker specific models, necessitating the use...
