Dynamic Temporal and Tactile Cueing: Quantifying Speech Motor Changes and Individual Factors That Contribute to Treatment Gains in Childhood Apraxia of Speech
Authors: Grigos Maria I. , Case Julie , Lu Ying , Lyu Zhuojun
Published: June 2023

Purpose:

Speech motor skill is refined over the course of practice, which is commonly reflected by increased accuracy and consistency. This research examined the relationship between auditory-perceptual ratings of word accuracy and measures of speech motor timing and variability at pre- and posttreatment in children with childhood apraxia of speech (CAS). Furthermore, the degree to which individual patterns of baseline probe word accuracy, receptive language, and cognition predicted response to treatment was explored.

Method:

Probe data were collected from seven children with CAS (aged 2;5–5;0 [years;months]) who received 6 weeks of Dynamic Temporal and Tactile Cueing (DTTC) treatment. Using a multidimensional approach to measuring speech performance, auditory-perceptual (whole-word accuracy), acoustic (whole-word duration), and kinematic (jaw movement variability) analyses were conducted on probe words produced pre- and posttreatment. Standardized tests of receptive language and cognition were administered pretreatment.

Results:

There was a negative relationship between auditory-perceptual measures of word accuracy and movement variability. Higher word accuracy was associated with lower jaw movement variability following intervention. There was a strong relationship between word accuracy and word duration at baseline, which became less robust posttreatment. Furthermore, baseline word accuracy was the only child-specific factor to predict response to DTTC treatment.

Conclusions:

Following a period of motor-based intervention, children with CAS appeared to refine speech motor control in conjunction with improvements in word accuracy. Those who demonstrated the poorest performance at treatment onset displayed the greatest degree of gains. Taken together, these results reflect a system-wide change following motor-based intervention.
Unique Continuation and Time Decay for a Higher-Order Water Wave Model
Authors: Pazoto Ademir F. , Vieira Miguel D. Soto
Published: June 2023

This work is devoted to prove the exponential decay for the energy of solutions of a higher order Korteweg–de Vries (KdV)–Benjamin–Bona–Mahony (BBM) equation on a periodic domain with a localized damping mechanism. Following the method in [L. Rosier and B.-Y. Zhang, J. Diff. Equ. 254 (2013) 141–178], which combines energy estimates, multipliers and compactness arguments, the problem is reduced to prove the Unique Continuation Property (UCP) for weak solutions of the model. Then, this is done by deriving Carleman estimates for a system of coupled elliptic-hyperbolic equations.
Event-triggered resilient consensus control of multiple unmanned systems against periodic DoS attacks based on state predictor
Authors: Yang Haichuan , Yu Ziquan , Zhang Youmin
Published: June 2023

This paper develops an event-triggered resilient consensus control method for the nonlinear multiple unmanned systems with a data-based autoregressive integrated moving average (ARIMA) agent state prediction mechanism against periodic denial-of-service (DoS) attacks. The state predictor is used to predict the state of neighbor agents during periodic DoS attacks and maintain consistent control of multiple unmanned systems under DoS attacks. Considering the existing prediction error between the actual state and the predicted state, the estimated error is regarded as the uncertainty system disturbance, which is dealt with by the designed disturbance observer. The estimated result is used in the design of the consistent controller to compensate for the system uncertainty error term. Furthermore, this paper investigates dynamic event-triggered consensus controllers to improve resilience and consensus under periodic DoS attacks and reduce the frequency of actuator output changes. It is proved that the Zeno behavior can be excluded. Finally, the resilience and consensus capability of the proposed controller and the superiority of introducing a state predictor are demonstrated through numerical simulations.
Secure motion control of micro-spacecraft using semi-homomorphic encryption
Authors: Shi Yongxia , Nekouei Ehsan , Hu Qinglei
Published: June 2023

This paper studies the secure motion control problem for micro-spacecraft systems. A novel semi-homomorphic encrypted control framework, consisting of a logarithmic quantizer, two uniform quantizers, and an encrypted control law based on the Paillier cryptosystem is developed. More specifically, a logarithmic quantizer is adopted as a digitizer to convert the continuous relative motion information to digital signals. Two uniform quantizers with different quantization sensitivities are designed to encode the control gain matrix and digitized motion information to integer values. Then, we develop an encrypted state-feedback control law based on the Paillier cryptosystem, which allows the controller to compute the control input using only encrypted data. Using the Lyapunov stability theory and the homomorphic property of the Paillier cryptosystem, we prove that all signals in the closed-loop system are uniformly ultimately bounded. Different from the traditional motion control laws of spacecraft, the proposed encrypted control framework ensures the security of the exchanged data over the communication network of the spacecraft, even when communication channels are eavesdropped by malicious adversaries. Finally, we verify the effectiveness of the proposed encrypted control framework using numerical simulations.
Extending the Embodied Simulation Hypothesis: Effects of Motor Simulation in the Mind on Memory Retrieval
Authors: Li Ruoqi , Fu Qingyang , Chen Yunqi
Published: June 2023

The embodied simulation hypothesis of modality-specific areas activation influencing language processing has matured over time. However, whether the idea can be applied to broader aspects other than language processing, such as memory processing, remains to be investigated. In this study, we extend the embodied simulation hypothesis, looking at the effects of motor simulation in mind, specifically handedness, on long-term memory retrieval. To test our hypothesis, we introduce two lists of Chinese characters as materials for memory and use old/new recognition tasks to measure retrieval performance. Our prediction of the results is that interfering with relevant motor systems (dominant hand) involved in memory encoding during retrieval will impair a person’s ability to recall. If our experimental results support our hypothesis, this not only provides strong evidence for the embodied simulation hypothesis but our research may also be applied to the field of memory, providing potential inspiration for memory enhancement.

The Influence of Feminist Movements on the Change of Female Images in Film and Television Dramas: Based on the Theory of Semiotics
Authors: Zhou Yuhan , Yang Fan , Yang Jialin , Wang Huiying
Published: June 2023

Semiotics mainly studies the role of symbols in signals, language, culture, human behavior, and social mechanisms. Based on the semiotic theory of female images, this article explores the relationship between feminist ideas and female appearance, behavior, and self-choice in film and television dramas, the reasons for the prevalence of feminism, and the reasons why feminism influences female images in film and television dramas.

Semiotics, a branch of linguistics, explores how signs and symbols convey meaning in various cultural and social contexts. It studies the use of signs and symbols to represent and communicate ideas, concepts, and values. The study of semiotics has been applied to various fields, including literature, art, and media, to analyze the meaning and function of symbols and their influence on social behavior and cultural norms.

In the context of feminist theory, semiotics has been used to analyze female images in various media, including film and television dramas. Feminist scholars argue that female images in the media are often constructed through symbolic representations, which reflect and reinforce gender stereotypes and patriarchal norms. Through the use of symbols, such as clothing, makeup, and body language, female characters in film and television dramas are often portrayed in ways that emphasize their femininity, beauty, and submissiveness.

Published: June 2023

Contemporary systems are trending toward 3D computer-aided design systems that integrate, network, and exhibit intelligence. The integration of parametric technology with ancient Chinese architecture can enhance the efficiency and quality of managing information on ancient buildings, thereby expanding the application scenarios of ancient architectural information models. By analyzing the construction characteristics of ancient Chinese carpentry work and modular systems, this research outlines the logic and methods for generating Chinese ancient architecture. The program’s parametric technology allows for adjusting variable parameters to produce carpentry work structures of varying scales and forms. Furthermore, this research establishes a library of parametric 3D components for ancient architecture, which can simplify the design process of contemporary antique architecture. Additionally, the parametrization of Chinese ancient architectures can function as an auxiliary tool for maintenance and repair techniques, serving as a storage mechanism for whole-life cycle information. This can enable the digital archiving of component information and model entities in an informative manner for managing existing ancient architectures.

Authors: Choi Yun Seong , Chang Moon Jong , Shin Young Bin , Kim Tae Woo , Chang Chong Bum , Kang Seung-Baik
Published: June 2023

This study aimed to determine whether there was a relationship between preoperative patient-reported outcome measures (PROMs) and satisfaction after total knee arthroplasty (TKA), and whether there was a relationship between the amount of improvement in PROM or final PROM and satisfaction and whether that relationship differed 1 and 2 years after TKA. The Western Ontario and McMaster University Osteoarthritis Index (WOMAC) and satisfaction of 267 limbs who underwent TKA were analyzed. Logistic regression analysis was performed to determine whether there was a relationship between preoperative WOMAC or improvement in WOMAC or final WOMAC and satisfaction at 1 and 2 years after TKA. Pearson and Filon's z test was performed to determine whether there was a difference in evaluating satisfaction between the amount of improvement in WOMAC and final WOMAC. There was no significant relationship between preoperative WOMAC and satisfaction. A higher improvement in WOMAC total score and better final WOMAC total scores at 1 and 2 years after TKA were related to greater satisfaction. At 1 year after TKA, there was no significant difference in evaluating satisfaction between the amount of improvement in WOMAC and final WOMAC. However, 2 years after TKA, the final WOMAC function and total score were more related to satisfaction than the amount of improvement in WOMAC function and total score. In the early postoperative period, there was no difference in evaluating satisfaction between the amount of improvement in WOMAC and final WOMAC, whereas over time, the final WOMAC was more related to satisfaction.
Transaxillary Capsulorrhaphy with Reimplantation to Correct Bottoming-Out Deformity in Breast Mycobacterial Periprosthetic Infection: A Case Report with Literature Review
Authors: Huang Tsung-Chun , Lee Jian-Jr , Yang Kuo-Hui , Chou Chia-Huei , Chang Yu-Chen
Published: June 2023

Augmentation mammoplasty is one of the most popular cosmetic surgeries, but there is a high reoperation rate (29.7%) commonly due to capsular contracture, implant malpositioning, infection, and unsatisfactory size. Although infection only accounts for 2% of cases, its management is very challenging, especially with nontuberculous mycobacteria (NTM) infection. Breast prosthetic NTM infection is a rare but is a disastrous condition with an incidence of approximately 0.013%. Immediate salvage reimplantation is usually not suggested, and most studies recommend a gap of 3 to 6 months after combination antibiotics therapy before reimplantation. However, delayed reimplantation often leads to great psychological stress and struggle between the doctor and patient. We present the case report of successful reimplantation in treating prosthetic NTM infections in a 28-year-old female. We discuss a novel technique “transaxillary capsulorrhaphy” to correct the bottoming-out deformity. One year after the combination of antibiotics and surgery, the follow-up computed tomography scan showed complete remission of NTM without recurrence. We discuss the surgical technique in detail. The 1-year follow-up assessment (photos and dynamic video) revealed good cosmesis and reliable correction using the new technique. This report is the first formal description and discussion of one-stage reimplantation following NTM infections. Transaxillary capsulorrhaphy allows for a successful salvage operation when an implant is displaced. This approach provides highly favorable result in eastern women undergoing revision augmentation mammoplasty. This study reflects level of evidence V, considering opinions of respected authorities based on clinical experience, descriptive studies, or reports of expert committees.

Methods This cohort study included consecutive aneurysmal SAH patients admitted to a tertiary center. Complete blood count was recorded at admission before treatment. White blood cell count, neutrophil count, lymphocyte count, platelet count, NLR, and PLR were collected as independent variables. Vasospasm occurrence-modified Rankin scale (mRS), Glasgow outcome scale (GOS), and Hunt-Hess score at admission and at 6 months were recorded as dependent variables. Multivariable logistic regression models were used to adjust for potential confounding and to assess the independent prognostic value of NLR and PLR at admission.

Results A total of 74.1% of the patients were female, with mean age of 55.6 ± 12.4 years. At admission, the median Hunt-Hess score was 2 (interquartile range [IQR] 1), and the median mFisher was 3 (IQR 1). Microsurgical clipping was the treatment for 66.2% of the patients. Angiographic vasospasm incidence was 16.5%. At 6 months, the median GOS was 4 (IQR 0.75), and the median mRS was 3 (IQR 1.5). Twenty-one patients (15.1%) died. Neutrophil-to-lymphocyte ratio and PLR levels did not differ between favorable and unfavorable (mRS > 2 or GOS < 4) functional outcomes. No variables were significantly associated with angiographic vasospasm.

Conclusion Admission NLR and PLR presented no value for prediction of functional outcome or angiographic vasospasm risk. Further research is needed in this field.
Associations between cognitive impairment and computed tomography perfusion in different lobes in acute stroke of the anterior circulation

Background Cognitive impairment (CI) during the acute phase of stroke should not be ignored. The present study analyzed the relationship between computed tomography perfusion (CTP) in different lobes and CI during the acute phase of stroke in patients with cerebral infarction.

Methods The present study included 125 subjects: 96 in the acute phase of stroke and 29 elderly healthy subjects as a control group. The Montreal Cognitive Assessment (MoCA) was used to evaluate the cognitive status of the two groups. The CTP scans include four parameters: cerebral blood flow (CBF), cerebral blood volume (CBV), time to peak (TTP), and mean transit time (MTT).

Results The MoCA scores for naming, language and delayed recall significantly decreased only in patients with left cerebral infarctions. The MTT of the left vessels in the occipital lobe and the CBF of the right vessels in the frontal lobe were negatively related to the MoCA scores of patients with left infarction. The CBV of the left vessels in the frontal lobe and the CBF of left vessels in the parietal lobe were positively linked to the MoCA scores of patients with left infarction. The CBF of the right vessels in the temporal lobe was positively related to the MoCA scores of patients with right infarction. Finally, the CBF of the left vessels in the temporal lobe was inversely correlated with the MoCA scores of patients with right infarctions.

Conclusion During the acute phase of stroke, CTP was closely associated with CI. Changed CTP could be a potential neuroimaging biomarker to predict CI during the acute phase of stroke.

Objective To observe the efficacy of treating senile chronic insomnia with spirit-calming and blood-nourishing decoction combined with Guasha (scraping) and acupuncture therapy.

Methods Seventy elderly patients with chronic insomnia were included and numbered by their visiting sequence. They were randomly divided into the control group and the observation group, 35 patients for each. Spirit-calming and blood-nourishing decoction was given to the control group, whereas Guasha (scraping) and acupuncture were applied together with the spirit-calming and blood-nourishing decoction to the observation group. Both groups were treated for 4 weeks before comparing their Pittsburgh Sleep Quality Index (PSQI) score and clinic efficacy.

Results PSQI scores of both groups were significantly lowered. Compared with the control group, the differences are statistically significant (p < 0.01). After treatment, the PSQI score of the observation group is (6.80 ± 1.37), whereas that of the control group is (10.83 ± 2.51). PSQI score of the observation group is lower (p < 0.01). The effective rate was 85.7% in the observation group and 62.9% in the control group. Difference of the effective rates of both groups is statistically significant (p < 0.01).

Conclusion Spirit-calming and blood-nourishing decoction combined with Guasha (scraping) and acupuncture is significantly effective in treating senile chronic insomnia. The combined therapy can effectively relieve the symptoms.

Published: June 2023

Objective The aim of this study was to determine the association between persistent bacterial vaginosis (BV) in pregnancy and risk for spontaneous preterm birth (sPTB).

Study Design Retrospective data from IBM MarketScan Commercial Database were analyzed. Women aged between 12 and 55 years with singleton gestations were included and linked to an outpatient medications database and medications prescribed during the pregnancy were analyzed. BV in pregnancy was determined based on both a diagnosis of BV and treatment with metronidazole and/or clindamycin, and persistent treatment of BV was defined as BV in more than one trimester or BV requiring more than one antibiotic prescription. Odds ratios were calculated comparing sPTB frequencies in those with BV, or persistent BV, to women without BV in pregnancy. Survival analysis using Kaplan–Meier curves for the gestational age at delivery was also performed.

Results Among a cohort of 2,538,606 women, 216,611 had an associated International Classification of Diseases, 9th Revision or 10th Revision code for diagnosis of BV alone, and 63,817 had both a diagnosis of BV and were treated with metronidazole and/or clindamycin. Overall, the frequency of sPTB among women treated with BV was 7.5% compared with 5.7% for women without BV who did not receive antibiotics. Relative to those without BV in pregnancy, odds ratios for sPTB were highest in those treated for BV in both the first and second trimester (1.66 [95% confidence interval [CI]: 1.52, 1.81]) or those with three or more prescriptions in pregnancy (1.48 [95% CI: 1.35, 1.63].

Conclusion Persistent BV may have a higher risk for sPTB than a single episode of BV in pregnancy.

The neurodevelopmental outcomes in children with tuberous sclerosis complex (TSC) with epileptic spasms remain underdiagnosed and might be responsible for significant morbidity and mortality burdens, even after spasms abate. The study was a cross-sectional study over 18 months at a tertiary care pediatric hospital, involving 30 children with TSC who had epileptic spasms. They were assessed with Diagnostic and Statistical Manual of Mental Disorders-5 criteria for autism spectrum disorder (ASD), attention deficit hyperactivity disorder (ADHD), and intellectual disability (ID), and childhood psychopathology measurement schedule (CPMS) for behavioral disorders. The median age at onset of epileptic spasms was 6.5 (1–12) months, and the age at enrolment was 5 (1–15) years. Of 30 children, 2 (6.7%) had only ADHD, 15 (50%) had only ID/GDD (global developmental delay), 4 (13.3%) had ASD and ID/GDD, 3 (10%) had ADHD and ID/GDD, and 6 (20%) had none. The median intelligence quotient/development quotient (IQ/DQ) score was 60.5 (20–105). CPMS assessment revealed significant behavioral abnormalities in almost half the children. Eight (26.7%) patients were completely seizure-free for at least 2 years, 8 (26.7%) had generalized tonic-clonic seizures, 11 (36.6%) had focal epilepsy, and 3 (10%) had evolved into Lennox-Gastaut syndrome. A high proportion of neurodevelopment disorders, including ASD, ADHD, ID/GDD, and behavioral disorders were seen in this pilot study with a small cohort of children with TSC with epileptic spasms.
