The standard model of quantum computation is based on quantum circuits, where the number and quality of the quantum gates composing the circuit influence the runtime and fidelity of the computation. The fidelity of the decomposition of quantum algorithms, represented as unitary matrices, to bounded depth quantum circuits depends strongly on the set of gates available for the decomposition routine. To investigate this dependence, we explore the design space of discrete quantum gate sets and present a software tool for comparative analysis of quantum processing units and control protocols based on their native gates. The evaluation is conditioned on a set of unitary transformations representing target use cases on the quantum processors. The cost function considers three key factors: (i) the statistical distribution of the decomposed circuits’ depth, (ii) the statistical distribution of process fidelities for the approximate decomposition, and (iii) the relative novelty of a gate set compared to other gate sets in terms of the aforementioned properties. The developed software, called YAQQ (Yet Another Quantum Quantizer), enables the discovery of an optimized set of quantum gates through this tunable joint cost function. To identify these gate sets, we use the novelty search algorithm, circuit decomposition techniques (like Solovay-Kitaev, Cartan, and quantum Shannon decomposition), and stochastic optimization to implement YAQQ within the Qiskit quantum simulator environment. YAQQ exploits reachability tradeoffs conceptually derived from quantum algorithmic information theory. Our results demonstrate the pragmatic application of identifying gate sets that are advantageous to popularly used quantum gate sets in representing quantum algorithms. Consequently, we demonstrate pragmatic use cases of YAQQ in comparing transversal logical gate sets in quantum error correction codes, designing optimal quantum instruction sets, and compiling to specific quantum processors. © 202

ABSTRACTTeachers’ epistemic beliefs may have consequences for their pedagogical work. We used previously developed scales to assess epistemic beliefs that teachers hold about learning, knowledge and knowing, and how they report putting such ideas into practice. The scales consisted of self-reported Likert-type statements considering collaborative knowledge building, valuing metacognition, certainty of knowledge, and a surface approach to learning. The participants were 127 subject-matter teachers from Finland and 97 teachers from Taiwan. Based on previous research, we constructed a confirmatory factor analysis (CFA) model for the Finnish sample and replicated this with the Taiwanese sample. We confirmed two factors: 1) reflective-collaborative theory (consisting of collaborative knowledge building and valuing metacognition scales) and 2) knowledge transmission theory (consisting of certainty of knowledge and simple learning scales) in both samples. In conclusion, essential and corresponding aspects of teachers’ epistemic beliefs and their reported practices were found. However, the results showed some cross-cultural *** is important to look at teachers’ epistemic beliefs because they may have consequences for teachers’ pedagogical work. These beliefs are a part of epistemic cognition which in this context consists of epistemic beliefs (beliefs about knowledge and learning) and how teachers report to put them into practice (e.g.). The aim of this study is to identify and assess teachers’ core epistemic beliefs and how such beliefs are associated with their practical ideas on pedagogy in two diverse cultural contexts. We used previously developed scales to assess beliefs that teachers hold about learning, knowledge and knowing, and how they report putting such ideas into practice. The scales consisted of self-reported Likert-type statements considering collaborative knowledge building, valuing metacognition, emphasising certainty of knowledge, and a surface ap

To understand the effect of abduction practice, this study involved students in creating their own abductive items, which the teachers implemented in an application named Abduction-Genius for all other students to play. To understand the learning effect of abduction, this study explored the correlates between field-independent cognitive style (FI-CS), external cognitive load (ECL), the achievement of offline posing of abduction items (hereafter, posing achievement), attitude towards engaging in abduction (hereafter, attitude) and game performance of playing the abduction game (hereafter, game performance). The results revealed: participants’ FI-CS was negatively related to their ECL but positively related to their posing achievement;their posing achievement was negatively related to their ECL;their ECL was not significantly related to attitude, but their posing achievement was positively related to attitude;and attitude was positively related to game performance. © 2023

Neural adaptation in the frontoparietal and motor cortex–sensorimotor circuits is crucial for acquiring visuomotor skills. However, the specific nature of highly dynamic neural connectivity in these circuits during the acquisition of visuomotor skills remains unclear. To achieve a more comprehensive understanding of the relationship between acquisition of visuomotor skills and neural connectivity, we used electroencephalographic coherence to capture highly dynamic nature of neural connectivity. We recruited 60 male novices who were randomly assigned to either the experimental group (EG) or the control group (CG). Participants in EG were asked to engage in repeated putting practice, but CG did not engage in golf practice. In addition, we analyzed the connectivity by using 8–13 Hz imaginary inter-site phase coherence in the frontoparietal networks (Fz-P3 and Fz-P4) and the motor cortex–sensorimotor networks (Cz-C3 and Cz-C4) during a golf putting task. To gain a deeper understanding of the dynamic nature of learning trajectories, we compared data at three time points: baseline (T1), 50% improvement from baseline (T2), and 100% improvement from baseline (T3). The results primarily focused on EG, an inverted U-shaped coherence curve was observed in the connectivity of the left motor cortex–sensorimotor circuit, whereas an increase in the connectivity of the right frontoparietal circuit from T2 to T3 was revealed. These results imply that the dynamics of cortico-cortical communication, particularly involving the left motor cortex–sensorimotor and frontal-left parietal circuits. In addition, our findings partially support Hikosaka et al.'s model and provide additional insight into the specific role of these circuits in visuomotor learning. © 2023 Society for Psychophysiological research.

Past studies of sentiment analysis have mainly applied algorithms based on vocabulary categories and emotional characteristics to detect the emotionality of text. However, the collocation of state-changing words and emotional vocabulary affects emotions. For example, adverbs of degree strengthen emotions, and negative adverbs reverse emotions. This study investigated the weighted effect of state-changing words on emotion. The research material comprised 73 state-changing words that were collocated with four emotions: happiness, sadness, fear, and anger. A total of 84 participants participated in the vocabulary assessment. The results revealed that state-changing words could be classified into four types: intensifying, weakening, neutralizing, and reversing. In a comparison of the weighting factors among emotions, the weighting effect of the same state-changing word in the positive emotion category was particularly evident. The results could serve as a reference for follow-up studies on detecting emotions in text. © 2023, The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature.

Both acute aerobic (AE) and resistance exercise (RE) have been acknowledged to be effective methods in enhancing executive function and brain-related P3 amplitudes. Nevertheless, the effect of acute concurrent exercise training (CET), combining both AE and RE, on executive function remains subject to speculation. Moreover, investigation of the mechanisms that underlie improvements in executive function would facilitate scientific understanding. Notably, lactate has emerged as a candidate among several potential mechanisms. Therefore, the main aim of the present study was to investigate the effect of acute CET on the cognitive flexibility dimension of executive function using behavioural and neuro-electric measures. A secondary aim was to determine the mediating effect of blood lactate in the acute exercise–executive function relationship. Seventy-eight young adults (38 women, 40 men;22.8 ± 1.8 years) were randomly assigned to one of the following groups: CET, AE, or reading control (RC). Cognitive flexibility was evaluated using the Task-Switching Test and its derived electroencephalography (EEG) was assessed immediately prior to and following each treatment. Fingertip lactate assays were taken prior to, at the midpoint, and after each treatment. Both acute CET and AE shortened response time regardless of test conditions when compared to the RC group. Greater P3 amplitude was observed following CET in the heterogeneous condition and under AE in the switch condition. A significant mediation of blood lactate for response time emerged in both the CET and AE groups for the heterogeneous and switch conditions. The blood lactate mediation was not reflected in P3 amplitude. The present findings suggest that acute CET leads to positive behavioural and neuro-electric alterations of cognitive flexibility, and its effect is similar to AE. Additionally, blood lactate serves as a mediator of the effects of acute exercise on executive function from a behavioural, but not neuro-el

research has addressed the benefits of immersive virtual reality (IVR) for affective learning rather than cognitive performance, indicating the necessity to explore what factors may influence learners’ attitudinal learning, defined as the result of instruction for changing learners’ attitudes, when engaging in immersive instructional mediums. This study proposes an affection-oriented model to understand the roles of young learners’ epistemic curiosity traits and triggered situational interest in their attitudinal learning from the affective, cognitive, and behavioral dimensions in IVR learning contexts. Through a series of PLS-SEM analyses with 90 elementary school students, the results of the measurement model test have verified the reliability and validity of the instruments employed in this study. The structural relationships among epistemic curiosity, situational interest, and attitudinal learning were also confirmed. The triggered situational interests of novelty and exploration intention during the IVR learning process were further identified as the mediators in the research model. While the students’ senses of novelty mediated the relationship between curiosity and cognitive attitudinal learning, their senses of interest in exploration intention mediated both the relationships between curiosity and affective attitudinal learning and between curiosity and behavioral attitudinal learning. This study contributed to establishing the theoretical framework for affection-oriented IVR learning.
