Observers make rapid eye movements to examine the world around them. Before an movement is made, attention covertly shifted location of object interest. The eyes typically will land at position which directed. Here we report that a goal-directed toward uniquely colored disrupted by appearance new but task-irrelevant object, unless subjects have sufficient amount time focus their on target prior object. In many instances, started moving before gaze shift color-singleton target. often landed...
Previous research has shown that when searching for a color singleton, top-down control cannot prevent attentional capture by an abrupt visual onset.The present addressed whether task-irrelevant onset would affect eye movement behavior singleton.Results show in many instances the moved direction of onset.There was evidence could neither entirely onsets nor from starting to move onset.Results suggest parallel programming 2 saccades: 1 voluntary goal-directed toward singleton target and...
In an effort to examine the flexibility with which attention can be allocated in visual space, we investigated whether subjects could selectively attend multiple noncontiguous locations field We examined this issue by precuing two separate areas of and requiring decide letters that appeared these matched or mismatched while distractors primed either match mismatch response were presented between cued If had no effect on performance, it would provide evidence divide over space Subjects able...
Previous research has shown that during visual search young and old adults' eye movements are equivalently influenced by the appearance of task-irrelevant abrupt onsets. The finding age-equivalent oculomotor capture is quite surprising in light abundant suggesting older adults exhibit poorer inhibitory control than on a variety different tasks. In present study, we examined hypothesis age invariant when subjects' awareness onsets low, but will have more difficulty inhibiting reflexive to...
The social support provided by chatbots is typically designed to mimic the way humans others. However, individuals have more conflicting attitudes toward providing emotional (e.g., empathy and encouragement) compared informational useful information advice). This difference may be related whether associate a certain type of with realm human mind they attribute human-like minds chatbots. In present study, we investigated perceiving in affects users’ acceptance various chatbot. experiment,...
We evaluated the diagnostic role of ultrasonography-guided core needle biopsy (CNB) according to ultrasonography features thyroid nodules that had inconclusive fine-needle aspiration (FNA) results.A total 88 in patients who underwent CNB because previous FNA results were evaluated. The classified into three groups based on findings: Group A, which was suspicious for papillary carcinoma (PTC); B, follicular (Hurthle cell) neoplasm; and C, lymphoma. final diagnoses determined by surgical...
We propose augmenting the empathetic capacities of social robots by integrating non-verbal cues. Our primary contribution is design and labeling four types cues, abbreviated as SAFE: Speech, Action (gesture), Facial expression, Emotion, in a robot. These cues are generated using Large Language Model (LLM). developed an LLM-based conversational system for robot assessed its alignment with defined human counselors. Preliminary results show distinct patterns robot's responses, such preference...
Two studies examined potential age-related differences in attentional capture.Subjects were instructed to move their eyes as quickly possible a color singleton target and identify small letter located inside it.On half the trials, new stimulus (i.e., sudden onset) appeared simultaneously with presentation of target.The onset was always task-irrelevant distractor.Response times lengthened, for both young old adults, whenever an distractor appeared, despite fact that subjects reported being...

Development of a 600 kJ Superconducting Magnetic Energy Storage (SMES) system is in progress by Korean Electric Research Institute (KERI). High-temperature superconducting (HTS) wires are going to be used for the winding system. The design HTS windings presented this paper. We considered BSCCO-2223 wire windings. operating temperature was decided 20 K which will accomplished conduction cooling method using cryo-coolers. Auto-Tuning Niching Genetic Algorithm adopted an optimization magnets...
The present study demonstrates that levels of extraversion and neuroticism can predict attentional performance during a change detection task. After completing task built on the flicker paradigm, participants were assessed for personality traits using Revised Eysenck Personality Questionnaire (EPQ-R). Multiple regression analyses revealed higher increased accuracies, while decreased accuracies. In addition, neurotic individuals exhibited sensitivity A' fixation dwell times. Hierarchical...
The article provides a brief review of the literature on relationship between aerobic Fitness and neurocognitive function, particularly as it relates to older adults. Cross-sectional studies provide strong support for beneficial influence fitness function. longitudinal or interventional literature, however, more equivocal this relationship. In discussing authors introduce new hypothesis, executive control/fitness which suggests that selective benefits will be observed with improvements in...
A numerical implementation of continuum sensitivity analysis in electromagnetic devices is presented, taking advantage the convenience existing finite-element codes. The state adjoint variables are computed by codes, and an load coefficients calculated using postprocessing data. Sensitivity evaluation can be performed outside it implemented without extensive access to insides standard codes.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
A method for deriving error estimates adaptive mesh refinement is presented. It based on the interelement boundary conditions, namely, continuity of normal components flux density and tangential magnetic field intensity. The elements that violate conditions significantly are considered to have large local errors refined. Applications magnetostatic problems involving Laplace's equation with Dirichlet Neumann in two-dimensional linear domains shown an extremely high rate convergence obtained.<...
