Published: October 2023

Purpose:
This study evaluates the extent to which automated indices of vocal development are stable and valid for predicting language in infants at increased familial likelihood for autism and/or language impairment and relatively lower likelihood infants.

Method:
A group of infants with autistic siblings (Sibs-autism; 20 infants) and a comparison group of infants with non-autistic siblings (Sibs-NA; 20 infants) wore Language ENvironment Analysis (LENA) recording devices for 16 hr on 2 days within a 1-week period. Extant software was used to derive several putative indices of vocal development from these recordings. Stability of these variables was examined across and within groups. Expressive and receptive language aggregates were calculated for each participant. Multiple regression analyses were used to (a) evaluate zero-order correlations for variables derived from LENA recordings with concurrent and future language and (b) test whether those associations were moderated by group status.

Results:
Both stability and validity differed by variable and group status. All variables reached acceptable stability in the Sibs-autism group within two to three observations, whereas stability of most variables was attenuated in the Sibs-NA group. No variables were associated with concurrent language in the theoretically motivated direction across groups, but two variables were strongly associated with concurrent expressive language in only the Sibs-NA group. Additionally, two variables were associated with later expressive language, though these correlations were again stronger in the Sibs-NA versus Sibs-autism group.

Conclusions:
Although selected automated indices of vocal development were stable in Sibs-autism and/or valid for predicting expressive language within Sibs-NA, no scores showed strong, theoretically motivated associations with language within the Sibs-autism group. Automated indices of vocal development may, thus, have limited validity or clinical utility for predicting language development in infants at elevated familial likelihood for autism.

The Effect of Language Dominance on Classic Semantic, Action, Emotional, and Phonemic Fluency in Unbalanced Bilinguals
Authors: Lam Boji P. W. , Yoon Jiyoung 
Published: October 2023

Objective:
Verbal fluency evaluation in bilingual speakers should include dual-language assessment to obtain a comprehensive profile of word retrieval abilities. This study is the first to compare classic semantic, action, emotional, and phonemic fluency in terms of the magnitude of their performance gaps between the dominant and nondominant language in unbalanced bilingual speakers. We also examined the quantitative relationship between language dominance and verbal fluency performance.

Method:
Twenty-six bilingual adults completed a comprehensive set of classic semantic (“animals,” “vegetables”), action (“do”), emotional (“happy,” “sad,” “afraid”), and phonemic (“F,” “A,” “S”) fluency tasks in their dominant language (English) and nondominant language (Spanish) in two sessions on separate days. Participants also completed subjective and objective measures of language proficiency.

Results:
All tasks yielded fewer correct responses in the nondominant language. The between-languages performance gap was the largest for “animals” and the smallest for emotional fluency. “Happy” yielded the most balanced performance among all semantic tasks and a positivity bias that was unaffected by language dominance. Finally, language dominance scores computed by a newly developed formula indicated relationships between self-rated proficiency and fluency performance.

Conclusions:
This study provides preliminary, normative data of classic semantic, action, emotional, and phonemic fluency that could be used to gauge unbalanced bilingual speakers' performance. Significant impacts of language dominance on “animals” demand caution in using this widely used classic semantic category in evaluating bilingual speakers' performance. The data also underscore the robustness of positivity biases in emotional fluency and the validity of using subjective measures to supplement neuropsychological assessment of fluency performance.
Associations Between Physiological Correlates of Cochlear Synaptopathy and Tinnitus in a Veteran Population
Authors: Bramhall Naomi F. , Theodoroff Sarah M. , McMillan Garnett P. , Kampel Sean D. , Buran Brad N. 
Published: October 2023

Purpose:
Animal models and human temporal bones indicate that noise exposure is a risk factor for cochlear synaptopathy, a possible etiology of tinnitus. Veterans are exposed to high levels of noise during military service. Therefore, synaptopathy may explain the high rates of noise-induced tinnitus among Veterans. Although synaptopathy cannot be directly evaluated in living humans, animal models indicate that several physiological measures are sensitive to synapse loss, including the auditory brainstem response (ABR), the middle ear muscle reflex (MEMR), and the envelope following response (EFR). The purpose of this study was to determine whether tinnitus is associated with reductions in physiological correlates of synaptopathy that parallel animal studies.

Method:
Participants with normal audiograms were grouped according to Veteran status and tinnitus report (Veterans with tinnitus, Veterans without tinnitus, and non-Veteran controls). The effects of being a Veteran with tinnitus on ABR, MEMR, and EFR measurements were independently modeled using Bayesian regression analysis.

Results:
Modeled point estimates of MEMR and EFR magnitude showed reductions for Veterans with tinnitus compared with non-Veterans, with the most evident reduction observed for the EFR. Two different approaches were used to provide context for the Veteran tinnitus effect on the EFR by comparing to age-related reductions in EFR magnitude and synapse numbers observed in previous studies. These analyses suggested that EFR magnitude/synapse counts were reduced in Veterans with tinnitus by roughly the same amount as over 20 years of aging.

Conclusion:
These findings suggest that cochlear synaptopathy may contribute to tinnitus perception in noise-exposed Veterans.

Supporting Mental Health in People Living With Aphasia: A Call to Action
Authors: Strong Katie A. 
Published: October 2023

Purpose:
This clinical focus article will provide an overview of the psychosocial impact of aphasia, with particular attention to depression and anxiety and barriers for accessing mental health services. The importance of interdisciplinary collaboration between speech-language pathologists (SLPs) and mental health providers as well as importance of stepped psychological care, peer befriending, support groups, and communication partner training will be highlighted. Resources will be provided for clinicians to utilize in increasing their knowledge and skills in supporting psychosocial issues for people with aphasia and their families.

Conclusions:
People living with aphasia are at high risk of mental health problems. There is a gap in the need for services and access to services due to the inherent language challenges caused by aphasia. SLPs need to take a leadership role in bridging this gap by partnering with mental health providers to increase access to services. Using the framework of stepped psychological care, SLPs can support people living with aphasia and their families in successfully living with aphasia.
Evaluation of an Innovative Case Management Strategy to Improve
Rehabilitation Coverage for People at High Risk of Permanent Work Disability: a
Feasibility Study
Authors: Remus Lea , Grope Marei , Lemke Stella , Bethge Matthias 
Published: October 2023

Abstract
PurposeOur process evaluation (trial registration: DRKS00022468) monitored
the implementation of a multi-component strategy including case management
aiming to improve rehabilitation coverage and work participation of people with
a high risk of permanent work disability.
Methods A risk score using administrative data, particularly on employment
and welfare benefits, was employed to identify individuals with higher
probability of receiving disability pension and therefore potentially needing
support. These individuals were contacted by post and encouraged to phone their
regional case manager if they needed assistance. Content for the intervention
components was developed collaboratively with the case managers. We examined the
sample reached, dose delivered, fidelity, dose received and satisfaction with
the intervention.
Results Out of 1074 individuals with high-risk scores were contacted,
there were 57 case managements. The participants reached were in poor health,
and 42.1% reported at least four diagnosed conditions, mostly
musculoskeletal and mental disorders. About two-thirds (63.0%) reported
poor work ability at baseline. On average, 72.5% of the content of the
initial telephone contacts, 88.7% of the content of the face-to-face
interviews and 45.2% of the content of the case management were
delivered. The participants were highly satisfied with the various components
and content of the intervention. Knowledge about rehabilitation improved
significantly, with 43 of the 57 participants (75.4%) applying for
rehabilitation, mainly medical rehabilitation. At the end of the case management
intervention, most participants (91.7%) were still employed.
Conclusion The risk score offers an opportunity to screen for people with
a high risk of permanent work disability. Case management participants found
participation worthwhile and were significantly better informed about
participation services after completing case management. More than every second
participant received medical or vocational rehabilitation.
Evaluation of Hip Characteristics in Baseball and Softball Athletes
with and Without Throwing Arm Pain
Authors: Oliver Gretchen D , Fava Anthony , Lozowski Billy , Zaremski Jason L , Holtz Kaila A , Bowers Robert L 
Published: October 2023

AbstractDuring throwing, the lower extremity assists in the generation and transfer of
momentum. Lower extremity stability assists in this transfer by providing a base
for distal mobility of the arm segments. This study aimed to determine
differences between hip rotational range of motion and strength based on the
presence of throwing-arm pain (yes/no) and throwing sport
(baseball/softball). We hypothesized those experiencing pain would
display decreases in hip range of motion and strength, and that softball players
would display greater range of motion than baseball, but less strength based on
sex-specific characteristics. Forty-four baseball (13±2 years,
165.2±13.0 cm, 58.5±13.4 kg) and 50 softball
players (13±2 years, 160.9±11.2 cm,
62.7±17.9 kg) participated. Multivariate analysis of variance
tests (2×2) determined differences in bilateral hip range of motion,
total arc of motion, and strength between pain status and sport. There were no
significant interactions (>0.05) for pain status and sport on hip range
of motion, total arc of motion, and strength. Furthermore, no significant main
effects (>0.05) were found for pain status or sport alone on range of
motion or strength. Future work should be directed at explaining the effects of
hip characteristics on the throwing motion and how it equates to throwing-arm
health.

Published: October 2023

AbstractEmpirical studies have indicated that benefit finding and optimism greatly help caregivers of children with intellectual or developmental disabilities. Specifically, it has been suggested that these two constructs serve as critical coping strategies for those engaged in the caregiving process. Here, a qualitative study was undertaken to explore the impacts of benefit finding and optimism on caregivers of children with intellectual and developmental disabilities in Malaysia. Twenty (20) caregivers of children with intellectual and developmental disabilities were interviewed concerning their perception and use of benefit finding and optimism. Results identified these strategies as supporting and guiding caregiving responsibilities and skills, improving personal growth, relationships and spirituality, as well as increasing positive perceptions. Therefore, policymakers and stakeholders in Malaysia should implement targeted interventions to facilitate and support caregivers in applying benefit-finding and optimism in their caregiving, thereby assisting them to better cope with the physical and mental demands of caring for children with intellectual and developmental disabilities.

Published: October 2023

Abstract
With the continuous advancement of deep-ultraviolet (DUV) communication and optoelectronic detection, research in this field has become a significant focal point in the scientific community. For more accurate information collection and transport, the photodetector array of many pixels is the key of the UV imaging and commnication systems, and its photoelectric performance seriously depends on semiconductor material and array layout. Gallium oxide (Ga2O3) is an emerging wide bandgap semicondutor material which has been widely used in DUV dectection. Therefore, this paper mainly focuses on Ga2O3 semiconductor detector array which has gained widespread attention in the field of DUV technique, from the perspective of individual device to array and its optoelectonic integration, for reviewing and discussing the research progress in design, fabrication, and application of Ga2O3 arrays in recent years. It includes the structure design and material selection of array units, units growth and array layout, response to solar blind light, the method of imaging and image recognition. Morever, the future development trend of the photodetector array has been analyzed and reflected, aiming to provide some useful suggestions for the optimizing array structure, improving patterned growth technology and material growth quality. As well as Ga2O3 optoelectronic devices and their applications are discussed in view of device physics and photophysics in detector.

Published: October 2023

Abstract
Multi-shell transition metal oxide hollow spheres show great potential for applications in energy storage because of their unique multilayered hollow structure with large specific surface area, short electron and charge transport paths, and structural stability. In this paper, the controlled synthesis of NiCo2O4, MnCo2O4, NiMn2O4 multi-shell layer structures was achieved by using the solvothermal method. As the anode materials for Li-ion batteries, the three multi-shell structures maintained good stability after 650 long cycles in the cyclic charge/discharge test. The in situ transmisssion electron microscope characterization combined with cyclic voltammetry tests demonstrated that the three anode materials NiCo2O4, MnCo2O4 and NiMn2O4 have similar charge/discharge transition mechanisms, and the multi-shell structure can effectively buffer the volume expansion and structural collapse during lithium embedding/delithiation to ensure the stability of the electrode structure and cycling performance. The research results can provide effective guidance for the synathesis and charging/discharging mechanism of multi-shell metal oxide lithium-ion battery anode materials.
The SNR of time-of-flight positron emission tomography data for joint reconstruction of the activity and attenuation images
Authors: Nuyts Johan , Defrise Michel , Morel Christian , Lecoq Paul 
Published: October 2023

Abstract

Objective. Measurement of the time-of-flight (TOF) difference of each coincident pair of photons increases the effective sensitivity of positron emission tomography (PET). Many authors have analyzed the benefit of TOF for quantification and hot spot detection in the reconstructed activity images. However, TOF not only improves the effective sensitivity, it also enables the joint reconstruction of the tracer concentration and attenuation images. This can be used to correct for errors in CT- or MR-derived attenuation maps, or to apply attenuation correction without the help of a second modality. This paper presents an analysis of the effect of TOF on the variance of the jointly reconstructed attenuation and (attenuation corrected) tracer concentration images. Approach. The analysis is performed for PET systems that have a distribution of possibly non-Gaussian TOF-kernels, and includes the conventional Gaussian TOF-kernel as a special case. Non-Gaussian TOF-kernels are often observed in novel detector designs, which make use of two (or more) different mechanisms to convert the incoming 511 keV photon to optical photons. The analytical result is validated with a simple 2D simulation. Main results. We show that if two different TOF-kernels are equivalent for image reconstruction with known attenuation, then they are also equivalent for joint reconstruction of the activity and the attenuation images. The variance increase in the activity, caused by also jointly reconstructing the attenuation image, vanishes when the TOF-resolution approaches perfection. Significance. These results are of interest for PET detector development and for the development of stand-alone PET systems.
Study on the influence of the information diffusion and vaccination behavior on disease transmission in multiplex networks
Authors: Huo Liang’an , Wu Bingjie 
Published: October 2023

Abstract
To investigate the influence of information diffusion and vaccination behavior on disease transmission. In this paper, a coupling model is proposed to describe the co-evolution process of information diffusion, vaccination behavior and disease transmission in multiplex network. In the information layer, two types of information are diffused, including the positive information and the negative information, respectively. During the process of information diffusion, the influence of mass media on information diffusion is considered, due to the herd effect, which type of information is believed to depend on the information state of the surrounding neighbors based on the Heaviside step function. In the behavioral layer, the individuals with different types of information will choose different immune behavioral responses, which in turn will influence the disease transmission. The coupling model was analyzed by using the Micro Markov Chain Approach (MMCA) to obtain state transition equations and the prevalence thresholds for disease. By simulating the simulation experiments, it demonstrates that the information diffusion has no direct effect on disease prevalence thresholds, but affects the proportion of infected; vaccination behavior has a significant effect on disease prevalence thresholds and also affects the proportion of infected. The results of the study suggest that when the disease transmission is within the controllable range, the stronger the diffusion of positive information, the higher the vaccination rate, which has a more positive influence on inhibiting disease transmission; once out of control, the official will lose trust, which is not conducive to disease control.

Published: October 2023

Abstract
Spanning trees (ST) have numerous applications in various fields, including computer science, graph theory, network design, and optimization. ST uses in designing efficient network topologies. In computer networks, a ST ensures that all nodes are connected while avoiding loops and redundant connections. This helps in minimizing network congestion and ensuring reliable communication. In routing protocols the ST’s play a crucial role such as the Spanning Tree Protocol (STP) and Rapid Spanning Tree Protocol (RSTP). These protocols are used to prevent network loops and establish a loop-free topology for efficient packet forwarding. In image processing the ST’s have applications in algorithms such as image segmentation and region merging. By constructing a minimum spanning tree based on pixel intensities or other image features, regions or objects can be efficiently grouped together. In wireless sensor networks, ST’s are employed to organize the network structure, reduce energy consumption, and enable efficient data collection. By constructing a spanning tree, sensor nodes can communicate with a central node or sink node while minimizing energy consumption and prolonging network lifetime. Motivated by the above applications and by the normalized Laplacian (NL) matrix, we obtained the spectrums of the n copies of K
