Summary: This study examined the co-occurrence of chunks and pause-defined processing units in Mandarin speech. The results showed that Mandarin chunks tended to be situated within a single processing unit, indicating that they are smaller units than processing units in spontaneous speech. The study also found that different chunk categories exhibited significantly different patterns in co-occurring with processing units, suggesting the influence of chunk properties on mental processing. Furthermore, the study revealed that chunks were processed fluently with fewer hesitations during production, indicating the holistic nature of chunks.

Summary: This study compared the articulatory patterns between patients with cerebellar disorders and basal ganglia disorders. The results showed that patients with Parkinson's disease exhibited significantly lower levels in the number of syllables, phonation time, diadochokinesis, and monolog tasks. In contrast, patients with spinocerebellar ataxia type 3 only had significantly lower number of syllables in the monolog. These findings suggest a relationship between speech and general motor functioning.

Summary: This paper presents the outcomes of corpus-based research on the prosodic features of schizophrenia, which include atypical prosody and pragmatic dysfunctions. The research analyzes a corpus of schizophrenic speech recorded during psychiatric interviews and compares it to a sampling of non-pathological speech. The findings reveal that patients' speech exhibits shorter and less structured information units, with an abnormal proportion of post-nuclear information. It is also characterized by frequent pauses and silence, hindering fluency and communication engagement. The study measures acoustic parameters related to prosodic prominence and identifies a flattening of Comment-prominence in patients, indicating impairments in performing illocutionary activities. Topic-prominence, on the other hand, shows higher values, suggesting effort in defining the domain of relevance in the speech force.

Summary: Plaque erosion, a distinct entity accounting for over 30% of acute coronary syndromes, can be diagnosed in vivo using optical coherence tomography. Patients with plaque erosion are younger, have fewer cardiovascular risk factors, lower plaque burden, and are more likely to present with non-ST-segment elevation ACS compared to those with plaque rupture. Early evidence suggests that antithrombotic therapy without stenting may be a safe and effective option for ACS caused by plaque erosion.

Summary: The study suggests that connectivity measured through EEG during ASL at 3 months may predict the later onset of autism spectrum disorder symptoms at 18 months. Additionally, the alpha coherence at 3 months correlates positively with word production at 18 months, indicating that early alterations in connectivity may serve as markers for predicting neurodevelopmental outcomes in infants.

Summary: Compared to traditional semiconductor control electronics, cryogenic single flux quantum electronics provide qubit measurement and control alternatives for scalable cryogenic quantum processors. By moving the control electronics to the 3 K stage, excess decoherence and loss can be avoided, resulting in an order of magnitude improvement in gate fidelity for scalable qubit control. The experiments showed agreement within daily fluctuations for qubit lifetime and coherence time, and 10% agreement for randomized benchmarking, demonstrating the promising potential of a Josephson microwave source operated at 3 K for scalable qubit control.

Summary: This study used uniaxial-stretching technology to select a mechanical regimen that can increase the migration of SAOS-2 cells in osteosarcoma. Through confocal and atomic force microscopy, it was found that a 24 h 1 Hz cyclic elongation can induce morphological changes in cells, as well as changes in cell adhesion and migration properties. These changes are independent of osteoblastic differentiation grade.

Summary: A novel domino annulation/oxidation reaction using heterocyclic ketene aminals and 2-aminochalcones has been developed for the selective synthesis of poly-substituted benzo[f]imidazo[2,1-a][2,7]naphthyridines and 3-azaheterocyclic substituted 2-arylquinolines. The reactions proceed smoothly under mild conditions without any additives. The synthesized benzo[f]imidazo[2,1-a][2,7]naphthyridine 3g exhibited a fluorescence effect, indicating potential applications in organic optical materials.

Summary: A compact and broadband 2 x 2 3 dB directional coupler (DC) based on the silicon nitride platform is designed. The proposed DC, equipped with a shallowly etched subwavelength gratings (SWG) gap, achieves a compact coupling region and a broad working bandwidth. Numerical analysis is conducted to evaluate the fabrication tolerance, and the results show that the impact of overlay mismatch can be neglected.

Summary: This study examined cortical sensitivity and categorical specificity to human faces in 7-month-old infants and adults using event-related potentials (ERPs). The results showed cortical specificity to human faces in both infants and adults, but infants showed higher sensitivity to cat faces, possibly due to differences in encoding unfamiliar cat stimuli.

Summary: Physical exercise is an effective way to preserve cognitive function by influencing the structural and functional characteristics of the brain. It enhances brain plasticity and has an additive effect when combined with cognitive training. This study used magnetoencephalography to monitor the brain processes associated with executive functions in older individuals who underwent a 12-month trial of physical and cognitive training. The addition of cognitive training improved performance in executive control tasks and reduced modulation of beta frequency band, indicating improved attentional control.

Summary: The use of dimension-based retro-cues improves performance in visual working memory tasks. This study investigates whether sustained attention is required for the dimension-based retro-cue benefit. The results demonstrate that perceptual interference or cognitive interruption attenuates the dimension-based retro-cue benefit, suggesting that sustained attention is necessary for effective prioritization of a specific dimension in visual working memory representations.

Summary: Body-brain interaction is a valuable approach for understanding neurodevelopmental conditions like autism spectrum disorder (ASD). This systematic review analyzes empirical evidence on the differences in autonomic and central nervous system responses to social stimuli between individuals with ASD and typically developing individuals. The review also examines the deviations in body-brain interaction during the processing of socially relevant information in ASD. Despite limitations such as small sample sizes and variability in measures, the results indicate atypicalities in both ANS and CNS signaling in individuals with ASD, with context-dependent effects. The study calls for unified guidelines and proposes future developments to enhance knowledge in this field.

Summary: Several studies have shown the possibility of decoding semantic representations directly from brain responses. However, there is a lack of research on decoding responses to written words, especially using time-sensitive imaging methods. This article discusses the challenges faced in decoding semantic representations from MEG responses to written words, emphasizing the differences in brain responses to pictures and orthographic stimuli. By raising awareness about these issues, the authors hope to stimulate further discussion and progress in this area.

Summary: Adults and children have different cortical auditory activation, which is relevant for cognitive performance in children, specifically inhibitory control. However, it is uncertain whether these differences result in functional differences in response inhibition between adults and children. Using M/EEG, we recorded auditory responses and found divergent brain-behavior associations between adults and children. Adults show negative associations between auditory cortical responses and inhibitory performance, while these associations are not significant in children or stronger responses are beneficial. There are also differences in brain responses between adults and children, with adults showing a shift in peak activation to frontomedial areas and children displaying prolonged obligatory responses in the auditory cortex.
