Integrated satellite-terrestrial networks can improve both the service coverage and spectral efficiency in spot-beam-based mobile satellite service system (MSS). In an integrated satellite-terrestrial network, MSS frequency is reused in both satellite spot beams and complementary ground component (CGC). Due to reuse of frequency, co-channel interference is present in both intra-component (betwe...

Background: Speech and language pathologists should include connected speech assessment as part of their evaluation for children with speech sound disorders. The purpose of the present study was to design and validate an instrument for assessment of articulation by story-retelling for Persian children.Methods: 261 typically developing children, aged 4-5 years old in Iran, Tehran, in 2016-2017, ...

This paper proposes to integrate multi-modal features using conditional random fields (CRF) for broadcast news story segmentation. We study story boundary cues from lexical, audio and video modalities, where lexical features consist of lexical similarity, chain strength and overall cohesiveness, acoustic features involve pause duration, pitch, speaker change and audio event type, and visual fea...

This paper discusses successes and failures of computational linguistics techniques in the study of how inter-event time intervals in a story affect the narrator’s use of different types of referring expressions. The success story shows that a conditional frequency distribution analysis of proper nouns and pronouns yields results that are consistent with our previous results – based on manual c...

The inter-subjective and dialogical nature of narrative therapy, as commonly practiced, remains unarticulated. Further, there currently exists no rigorous empirical research investigating the process or outcome of narrative therapy. The research aim, to investigate the process and outcome of narrative therapy, comprised theoretical and empirical objectives. The first objective was to articulate...

Computational modeling has served a powerful tool for studying cross-situational word learning. Previous research has focused on convergence behaviors in a static environment, ignoring dynamic cognitive aspects of concept change. Here we investigate concept drift in word learning in story-telling situations. Informed by findings in cognitive neuroscience, we hypothesize that a large ensemble of...

What mechanisms support our ability to estimate durations on the order of minutes? Behavioral studies in humans have shown that changes in contextual features lead to overestimation of past durations. Based on evidence that the medial temporal lobes and prefrontal cortex represent contextual features, we related the degree of fMRI pattern change in these regions with people's subsequent duratio...

Dislocation dynamics simulations of the interaction between prismatic dipolar loops and a glide screw dislocation are presented. As a result of stress gradients generated by the glide dislocation, dipolar loops execute drift motion along their glide cylinders. Simulations of the combined motion of two dipolar loops in the stress field of a glide dislocation clearly show that inter-loop forces a...

Seismic isolation systems exposed to far-fault earthquakes can reduce floor accelerations and story drift ratios acceptable levels. However, they exhibit different structural performances in each earthquake due excitation frequency contents. By optimizing the system parameters, their performance may be maintained at best level under earthquakes. In this study, optimization of parameters nonline...
