Streszczenie:

Dynamic and real-time MRI (rtMRI) of human speech is an active field of research, with interest from both the linguistics and clinical communities. At present, different research groups are investigating a range of rtMRI acquisition and reconstruction approaches to visualise the speech organs. Similar to other moving organs, it is difficult to create a physical phantom of the speech organs to optimise these approaches; therefore, the optimisation requires extensive scanner access and imaging of volunteers. As previously demonstrated in cardiac imaging, realistic numerical phantoms can be useful tools for optimising rtMRI approaches and reduce reliance on scanner access and imaging volunteers. However, currently, no such speech rtMRI phantom exists. In this work, a numerical phantom for optimising speech rtMRI approaches was developed and tested on different reconstruction schemes. The novel phantom comprised a dynamic image series and corresponding k-space data of a single mid-sagittal slice with a temporal resolution of 30 frames per second (fps). The phantom was developed based on images of a volunteer acquired at a frame rate of 10 fps. The creation of the numerical phantom involved the following steps: image acquisition, image enhancement, segmentation, mask optimisation, through-time and spatial interpolation and finally the derived k-space phantom. The phantom was used to: (1) test different k-space sampling schemes (Cartesian, radial and spiral); (2) create lower frame rate acquisitions by simulating segmented k-space acquisitions; (3) simulate parallel imaging reconstructions (SENSE and GRAPPA). This demonstrated how such a numerical phantom could be used to optimise images and test multiple sampling strategies without extensive scanner access.

The teleost fish are thought to lack the mineralocorticoid hormone aldosterone but possess mineralocorticoid receptor (MR) homologs. Here we describe the characterization of two rainbow trout (Oncorhynchus mykiss) MRs, called rtMRa and rtMRb. The open reading frame of rtMRa cDNA encoded a protein of 1041 amino acids. The rtMRb predicted protein sequence is similar, differing in only 10 amino acids in the nonconserved A/B domain and lacking a three-amino acid insertion between the two zinc fingers of the C domain. Expression of rtMR mRNA (sum of both forms), measured in juvenile trout by real-time RT-PCR, shows that the transcripts are ubiquitous. Expression was significantly higher in brain than the other tissues studied (eye, trunk kidney, head kidney, gut, gills, liver, spleen, ovary, heart, white muscle, skin). Hormonal stimulation of receptor transactivation activity was studied in COS-7 cells transiently cotransfected with receptor cDNA and a mouse mammary tumor virus-luciferase reporter. The mineralocorticoids 11-deoxycorticosterone and aldosterone were more potent enhancers of rtMRa transcriptional activity (EC50 = 1.6 ± 0.5 × 10−10 and 1.1 ± 0.4 × 10−10m, respectively) than the glucocorticoids cortisol and 11-deoxycortisol (EC50 = 1.1 ± 0.3 × 10−9 and 3.7 ± 1.9 × 10−9m, respectively). A similar response was observed in transactivation assays with rtMRb. These results are discussed in the view of reported circulating levels of corticosteroids in trout.

Real-time fMRI (rtfMRI) neurofeedback (NF) facilitates volitional control over brain activity and the modulation of associated mental functions. The NF signals of traditional rtfMRI-NF studies predominantly reflect neuronal activity within ROIs. In this study, we describe a novel rtfMRI-NF approach that includes a functional connectivity (FC) component in the NF signal (FC-added rtfMRI-NF). We estimated the efficacy of the FC-added rtfMRI-NF method by applying it to nicotine-dependent heavy smokers in an effort to reduce cigarette craving. ACC and medial pFC as well as the posterior cingulate cortex and precuneus are associated with cigarette craving and were chosen as ROIs. Fourteen heavy smokers were randomly assigned to receive one of two types of NF: traditional activity-based rtfMRI-NF or FC-added rtfMRI-NF. Participants received rtfMRI-NF training during two separate visits after overnight smoking cessation, and cigarette craving score was assessed. The FC-added rtfMRI-NF resulted in greater neuronal activity and increased FC between the targeted ROIs than the traditional activity-based rtfMRI-NF and resulted in lower craving score. In the FC-added rtfMRI-NF condition, the average of neuronal activity and FC was tightly associated with craving score (Bonferroni-corrected p = .028). However, in the activity-based rtfMRI-NF condition, no association was detected (uncorrected p > .081). Non-rtfMRI data analysis also showed enhanced neuronal activity and FC with FC-added NF than with activity-based NF. These results demonstrate that FC-added rtfMRI-NF facilitates greater volitional control over brain activity and connectivity and greater modulation of mental function than activity-based rtfMRI-NF.

Streszczenie:

Road transport safety is an important part of transport construction in China. China is now the world’s second-largest country for road traffic deaths. Research on the road traffic mortality rate (RTMR) in China is of great significance in promoting sustainable development in global traffic. This study analyzes the RTMR in 31 provinces in China between 2003 and 2018. Research shows that the RTMR of China demonstrated a downward trend after 2004, but it increased slightly after reaching the lowest points in 2015. The RTMR in coastal and western areas was quite high, requiring targeted management and prevention. During the study period, the RTMR in Guangdong and Tibet improved greatly, whereas the RTMR in Hubei and Guangxi deteriorated. Tobit model results show that economic development level, medical assistance level and government expenditure on health are significantly negatively correlated with RTMR, while urbanization level and motorization level significantly promote RTMR. This study provides macro policy support for improving traffic safety in China.

The purpose of this study was to qualify method-centered teaching approaches by investigating the effects of the reflective teaching model for reading comprehension (RTMRC) on ninth-grade students’ English reading comprehension achievement in Myanmar. Three kinds of method-centered teaching approaches, namely reciprocal teaching, interactive teaching, and questioning, were qualified, compared, and examined while using the RTMRC. A quasi-experimental research design was used. The participants included 458 ninth-grade students, five English teachers, and 10 peer observers. Pre- and post-tests, a student questionnaire, and an observation scheme were used to assess the effectiveness of the RTMRC over 15 weeks. Structural equation modeling, Rasch analysis, analysis of covariance (ANCOVA), effect size (Cohen’s d), and various descriptive statistics revealed that the teachers’ reflections on the instructional context were very effective for student reading comprehension achievement, the students appreciated interactive teaching the most, students’ achievements for the literal, inferential, and evaluative comprehension questions were the highest, and the RTMRC was more effective than other traditional teaching methods. In essence, the RTMRC can assist English language teachers in improving their students’ reading comprehension.

This study aimed to investigate the sustainability of an instructional design utilizing the novel approach of the Reflective Teaching Model for Reading Comprehension (RTMRC), and to continuously develop and validate instruments for reflective measures to ensure the sustainable teaching of reading comprehension. The RTMRC design was featured based on two main parts: the reflective teaching process (planning, acting, reflecting and evaluating) and the reading comprehension process (reader, strategy, text and task). Then, a quasi-experiment (the pre- and post-test control group design) was conducted with 168 grade-9 students to assess the performance of the RTMRC in practice. The reflective questionnaire was also applied as an instrument to gather feedback from students about the instructional context, with the aim of supporting the sustainable reflective practices of the teacher. The reading achievement in the experimental group was evaluated and fostered using this model. Through the analyses of t-tests and Cohen’s d effect size, it was found that the experimental group teaching with RTMRC outperformed the control group without RTMRC teaching. Using exploratory factor analysis, confirmatory factor analysis, Rasch analysis and testing measurement invariance across groups, we report that the instruments were found to be valid for measuring the effect of the RTMRC in teaching reading comprehension in English Language Teaching (ELT) in a sustainable manner.

Tests for recent HIV infection (TRI) distinguish recent from long-term HIV infections using markers of antibody maturation. The limiting antigen avidity enzyme immunoassay (LAg EIA) is widely used with HIV viral load (VL) in a recent infection testing algorithm (RITA) to improve classification of recent infection status, estimate population-level HIV incidence, and monitor trends in HIV transmission. A novel rapid test for recent HIV infection (RTRI), Asanté™, can determine HIV serostatus and HIV recency within minutes on a lateral flow device through visual assessment of test strip or reader device. We conducted a field-based laboratory evaluation of the RTRI among pregnant adolescent girls and young women (AGYW) attending antenatal clinics (ANC) in Malawi.We enrolled pregnant AGYW aged <25 years testing HIV-positive for the first time at their first ANC visit from 121 ANCs in four high-HIV burden districts. Consenting participants provided blood for recency testing using LAg EIA and RTRI, which were tested in central laboratories. Specimens with LAg EIA normalized optical density values ≤2.0 were classified as probable recent infections. RTRI results were based on: (1) visual assessment: presence of a long-term line (LT) indicating non-recent infection and absence of the line indicating recent infection; or (2) a reader; specimens with LT line intensity units <3.0 were classified as probable recent infections. VL was measured for specimens classified as a probable recent infections by either assay; those with HIV-1 RNA ≥1,000 copies/mL were classified as confirmed recent infections. We evaluated the performance of the RTRI by calculating correlation between RTRI and LAg EIA results, and percent agreement and kappa between RTRI and LAg EIA RITA results.Between November 2017 to June 2018, 380 specimens were available for RTRI evaluation; 376 (98.9%) were confirmed HIV-positive on RTRI. Spearman’s rho between RTRI and LAg EIA was 0.72 indicating strong correlation. Percent agreement and kappa between RTRI- and LAg EIA-based RITAs were >90% and >0.65 respectively indicating substantial agreement between the RITAs.This was the first field evaluation of an RTRI in sub-Saharan Africa, which demonstrated good performance of the assay and feasibility of integrating RTRI into routine HIV testing services for real-time surveillance of recent HIV infection.

Real-time functional MRI neurofeedback (rtfMRI-NF) is a noninvasive technique that extracts concurrent brain states and provides feedback to subjects in an online method. Our study aims to investigate the effect of rtfMRI-NF on amygdala-based emotion self-regulation by analyzing resting-state functional connectivity. We conducted a task experiment to train subjects in self-regulating amygdala activity in response to emotional stimuli. Twenty subjects were divided into two groups. The up-regulate group (URG) viewed positive stimulus, while the down-regulate group (DRG) viewed negative stimulus. The rtfMRI-NF experiment paradigm consisted of three conditions. The URG’s percent amplitude fluctuation (PerAF) scores are significant, indicating that positive emotions may be a partial side effect, with increased activity in the left hemisphere. Resting-state functional connectivity was analyzed via a paired-sample t-test before and after neurofeedback training. Brain network properties and functional connectivity analysis showed a significant difference between the default mode network (DMN) and the brain region associated with the limbic system. These results reveal to some extent the mechanism of neurofeedback training to improve individuals’ emotional regulate regulation ability. Our study has shown that rtfMRI-neurofeedback training can effectively enhance the ability to voluntarily control brain responses. Furthermore, the results of the functional analysis have revealed distinct changes in the amygdala functional connectivity circuits following rtfMRI-neurofeedback training. These findings may suggest the potential clinical applications of rtfMRI-neurofeedback as a new therapy for emotionally related mental disorders.

Real-time fMRI neurofeedback (rtfMRI-nf) is a promising tool for enhancing emotion regulation capability of subjects and for the potential alleviation of neuropsychiatric disorders. The amygdala is composed of structurally and functionally distinct nuclei, such as the basolateral amygdala (BLA) and centromedial amygdala (CMA), both of which are involved in emotion processing, generation, and regulation. However, the effect of rtfMRI-nf on the resting-state functional connectivity (rsFC) of BLA and CMA remains to be elucidated. In our study, participants were provided with ongoing information on their emotion states by using real-time multivariate voxel pattern analysis. Results showed that participants presented significantly increased rsFC of BLA and CMA with prefrontal cortex, rostral anterior cingulate cortex, and some others related to emotion after rtfMRI-nf training. The findings provide important evidence for the emotion regulation effectiveness of rtfMRI-nf training and indicate its usefulness as a tool for the self-regulation of emotion.

Streszczenie:

Real-time Magnetic Resonance Imaging (rtMRI) is a tool used exhaustively in speech science and linguistics to understand the dynamics of the speech production process across languages and health conditions. rtMRI has two advantages over other methods which capture articulatory movement, like X-ray, Ultrasound and Electromagnetic articulography - it is non invasive, and it captures a complete view of the vocal tract including pharyngeal structures. The rtMRI video provides spatio-temporal information of speech articulatory movements, which helps in modeling speech production. For this purpose, a common step is to obtain the air-tissue boundary (ATB) segmentation in all frames of the rtMRI video. The accurate estimation of ATBs of the upper airway of the vocal tract is essential for many speech processing applications like speaker verification, text-to-speech synthesis, visual augmentation for synthesized articulatory videos, and analysis of vocal tract movement. Thus, it is necessary to have an accurate air-tissue boundary segmentation in every frame of the rtMRI videos. The best performance in ATB segmentation of rtMRI videos in speech production, in unseen subject conditions, is known to be achieved by a 3-dimensional convolutional neural network (3D-CNN) model. In seen subject conditions, both 3D-CNN and 2-dimensional deep convolutional encoder-decoder network (SegNet) show similar performance. However, the evaluation of these models, as well as other ATB segmentation techniques reported in literature, has been done using Dynamic Time Warping (DTW) distance between the entire original and predicted boundaries or contours. Such an evaluation measure may not capture local errors in the predicted contour. Careful analysis of predicted contours reveals errors in regions like the velum part and tongue base section, which are not captured in a global evaluation metric like DTW distance. In this thesis, such errors are automatically detected and a novel correction scheme is proposed for them. Two new evaluation metrics are also proposed for ATB segmentation, separately for each contour, to explicitly capture errors in these contours. Moreover, the state-of-the-art models use overall binary cross entropy as the loss function during model training. However, such a global loss function does not give enough emphasis on regions which are more prone to errors. In this thesis, together with global loss, the use of regional loss functions has been explored, which focus on areas of the contours which have been analyzed as error prone in the analysis. Two different losses are considered in the regions around velum and tongue base - binary cross entropy (BCE) loss and dice loss. It is observed that dice-loss based models perform better than their BCE loss based counterparts.

Thromboplastins from different animal species vary in their relative sensitivity to non-activated VII and activated VII (Vila) in plasma and this has formed the basis of Vila determinations using bovine and human thromboplastins. Since the use of human thromboplastin is now being discontinued we have re-evaluated the assessment of Vila using bovine and rabbit thromboplastins (BT and RT respectively). Citrated plasma was prepared from four normal individuals and maintained at 4°C in glass containers for 24 hours to promote the formation of Vila. Each plasma was subsampled at 0, 2, 4, 6 and 24 hours and factor VII assays performed using BT and two different rabbit preparations viz, (a) Manchester Reagent (RTmr, ISI = 1.16) and (b) Diagen phenolised (RT diagenlSI = 1.4). Results were expressed as the ratio BT/RT. With all thromboplastins factor VII activity increased with time. The changes were most marked using BT with much smaller increments occurring using the rabbit preparatrions. RTmr was less sensitive to Vila than RT diagen. The ratio BT/RTmr thus provides an index of Vila.Using this method we determined Vila in plasma samples from 29 normal subjects. Results obtained were x = 1 ,00;s.d. = 0.126; normal range 0.72 - 1.25 The method was applied to 29 plasma samples from 19 patients with disseminated intravascular coagulation giving BT/RTmr = 1.71 (range 0.92 - 3.38). We conclude that the ratio of Factor VII measured by bovine and rabbit thromboplastins respectively provides an index of Factor VII activation in plasma.

Streszczenie:

Under repetitive trainloads, lateral track displacement causes alignment irregularities in ballasted track structures, which in turn leads to gradual track state deterioration. For the prediction of alignment irregularities development, the Railway Technical Research Institute (RTRI) in Japan has adopted the analytical method of track mechanics to develop an alignment irregularity prediction model which takes track strength, deformation, operational conditions and maintenance & repair into overall account. Based on the actual situation of railway lines in China, this paper sets out to examine the pattern of changes in track alignment irregularity in relation to gross passing tonnage and develop a model of local alignment irregularity degradation called MPLIPM. The model uses track waveform data generated by the track geometry car to predict track alignment irregularities of a unit section. After comparing the predicted values with the actually measured data, evaluation results verified the accuracy of this model.

Streszczenie:

Conventional radiography has been the accepted nondestructive testing (NDT) method used for many years to either accept or reject a field weld in the pipeline industry. However, conventional radiography requires the expense of film, developing chemicals, and manpower for film development. It also normally has a delay of 2 hours or more between when the weld was radiographed and when the radiographic film of the weld is available for interpretation. Over the last few years, a newer approach to performing radiographic testing, called real-time radiography, has been used in several different types of field inspection operations. The real-time radiography system forms the image with optical imaging in lieu of photographic film. The objectives of this project were to (1) Integrate various optimized real-time radiographic components (identified as a result of the previous project) into a field-usable, real-time-radiographic inspection (RTRI) system for single-wall inspection of pipeline girth welds and (2) Demonstrate the system in the field.
