Management of clutter is an important factor in the design user interfaces and information visualizations, allowing improved usability aesthetics. However, not a well defined concept. In this paper, we present Feature Congestion measure display clutter. This based upon extensive modeling saliency elements display, new operational definition The current implementation two features: color luminance contrast. We have tested on maps that observers ranked by perceived Results show good agreement...

Background Graph theory and machine learning have been shown to be effective ways of classifying different stages Alzheimer’s disease (AD). Most previous studies only focused on inter-subject classification with single-mode neuroimaging data. However, whether this can truly reflect the changes in structure function brain region progression remains unverified. In current study, we aimed evaluate framework, which combines structural Magnetic Resonance Imaging (sMRI) resting-state functional...

To study the differences in functional brain networks between eyes-closed (EC) and eyes-open (EO) at resting state, electroencephalographic (EEG) activity was recorded 21 normal adults during EC EO states. The synchronization likelihood (SL) applied to measure correlations all pairwise EEG channels, then SL matrices were converted graphs by thresholding. Graphs measured topological parameters theta (4–7 Hz), alpha (8–13 beta (14–30 Hz) bands. By changing from states, mean cluster...

Using the Pearson correlation coefficient to constructing functional brain network has been evidenced be an effective means diagnose different stages of mild cognitive impairment (MCI) disease. In this study, we investigated efficacy a classification framework distinguish early (EMCI) from late (LMCI) by using features derived three frequency bands (full-band: 0.01-0.08 Hz; slow-4: 0.027-0.08 slow-5: 0.01-0.027 Hz) at Rest. Graphic theory was performed calculate and analyze relationship...

This study examined the relationship between moral sensitivity and prosocial behavior, as well mediating role of disengagement reciprocity norms. Totally 567 college students completed Dispositional Moral Sensitivity Questionnaire, Disengagement Scale for Chinese Students, Reciprocity Norm Scale, Prosocial Tendencies Measure Adolescent. The results showed that, norms played multiple roles behavior. Specifically, affected behavior through independent effect disengagement, norms, chain In...

Abstract In recent years, deep learning (DL)-based automatic view classification of 2D transthoracic echocardiography (TTE) has demonstrated strong performance, but not fully addressed key clinical requirements such as coverage, accuracy, inference delay, and the need for thorough exploration performance in real-world settings. We proposed a requirement-driven DL framework, TTESlowFast, accurate efficient video-level TTE classification. This framework is based on SlowFast architecture...

Abstract Background End‐to‐end automatic detection of cardiac phase in multibeat echocardiograms is crucial for measuring parameters clinical scenarios. However, existing studies face limitations due to the high cost data annotation and collection, time‐consuming processes. Purpose This study introduces a novel echocardiographic network, EchoPhaseNet, perform fast accurate variable‐length sequences, with low costs limited data. Materials methods Five datasets were used this study, including...

Abstract The ability to perceive, understand, and react the feelings of others' pain is referred as empathy for which composed two components, affective‐perceptual cognitive‐evaluative empathy. Recent reviews on neural mechanisms empathetic showed anterior insula (AI) cortex a core circuit However, little known about modulation brain anatomy empathic responses by trait measures (trait empathy). Thus, we investigated whether individual variation in personality associated with structure...

Recent studies have suggested that the right inferior frontal gyrus (rIFG) may be involved in pain-related empathy. To verify role of rIFG, we performed a functional magnetic resonance imaging (fMRI) experiment to replicate previous research and further designed noninvasive repetitive transcranial stimulation (rTMS) probe causal rIFG empathy processing. We assigned 74 volunteers (37 females) three groups. Group 1 (n = 26) task which participants were required perceive pain others (task pain:...

Obsessive-compulsive disorder (OCD) is a common neuropsychiatric characterized by intrusive thoughts (obsessions) and repetitive behaviors (compulsions), few studies have assessed the whole-brain functional connectivity architecture of OCD with electroencephalogram (EEG) during different resting states. Graph theory network-based statistics (NBS) were employed to examine neural synchronization (FC) based on phase-locking value (PLV) patients healthy controls (HCs) eyes-closed (EC) eyes-open...

Abstract While converging sources of evidence point to the possibility a large‐scale distributed network for semantic cognition, consensus regarding underlying subregions and their specific function in this has not been reached. In current study, we combined functional magnetic resonance imaging (fMRI) transcranial stimulation (TMS) methodology investigate neural basis cognition Mandarin Chinese. fMRI experiment, strong activations were observed left inferior frontal gyrus (IFG) middle...

Although previous studies have shown that fronto-parietal attentional networks play a crucial role in bottom-up and top-down processes, the relative contribution of frontal parietal cortices to these processes remains elusive. Here we used transcranial magnetic stimulation (TMS) interfere with activity right dorsal prefrontal cortex (DLPFC) or posterior (PPC), immediately prior onset visual search display. Participants searched target defined by color orientation "pop-out" "search"...

The contents of working memory (WM) can affect the subsequent visual search performance, resulting in either beneficial or cost effects, when target is included spatially dissociated from memorized contents, respectively. right dorsolateral prefrontal cortex (rDLPFC) and posterior parietal (rPPC) have been suggested to be associated with congruence/incongruence effects content target. Thus, present study, we investigated role DLPFC PPC controlling interaction between WM attention during a...

Smooth pursuit of natural objects requires flexible allocation attention to inspect features. However, it has been reported that is focused at the fovea during pursuit. We ask here if foveal obligatory pursuit, or can be disengaged. Observers tracked a stimulus composed central dot surrounded by four others and identified one dots when dimmed. Extinguishing center before dimming improved task performance, suggesting was released from it. To determine automatically usurped attention, we...

The ability to focus on task-relevant information, while suppressing distraction, is critical for human cognition and behavior. Using a delayed-match-to-sample (DMS) task, we investigated the effects of emotional face distractors (positive, negative, neutral faces) early late phases visual short-term memory (VSTM) maintenance intervals, using low high VSTM loads. Behavioral results showed decreased accuracy delayed reaction times (RTs) vs. load. Event-related potentials (ERPs) enhanced...

Working memory (WM) training is a prevalent intervention for multiple cognitive deficits, however, the transfer effects to other tasks from gains in WM induced by different techniques still remains controversial. Therefore, current study recruited three groups of young adults investigate transference, with N-back group (NBG) (n = 50) on dual n-back task, Memory Palace (MPG) method loci, and blank control (BCG) 48) receiving no training. Our results showed that both separately improved...

The experience in virtual reality (VR) is unique, that observers are a real-world location while browsing through scene. Previous studies have investigated the effect of environment on distance estimation. However, it unclear how influences estimation VR. Here, we measured using bisection (Experiment 1) and blind-walking (Experiments 2 3) method. Participants performed judgments VR, which rendered either indoor or outdoor scenes. Experiments were also carried out locations. In experiment,...
