It is because diabetes mellitus is a severe and common chronic disease affecting almost all populations in many countries. This study collected retrospective clinical data from five patients receiving insulin therapy in the ICU of HUSM. The auto-regressive with exogenous (ARX) and auto-regressive moving average with exogenous (ARMAX) model structure techniques were used to generate a model converter that best describes the glucose and insulin relationship of the subject. The simulation of ARX were started from model order (1,1,1) to model order (5,5,10) while, for ARMAX the simulation was started from model order (1,1,1,1) until model order (5,5,5,10). The three best model orders from ARX and ARMAX models were chosen. The best model fits for ARX and ARMAX were compared to identify the best model order in predicting the glucose-insulin system. The finding indicated that the ARX model recorded the best model fit for all patients in the 5th model order. Meanwhile, the ARMAX model recorded patients with different medical backgrounds and produced a different model order. Besides, the ARMAX model was considered the best option for most of the patients in this study due to the highest model fit, time-delay and lowest percentage of peak error. A more extensive data set may be required to ensure the structure of the model precisely describe the glucose-insulin interaction of the patient.Clinical Relevance– This study establishes a prediction model of the glucose-insulin system that can assist clinicians in providing appropriate insulin value and consequently reduce the incidence of hypoglycemia and hyperglycemia.","PeriodicalId":146681,"journal":{"name":"2022 IEEE-EMBS Conference on Biomedical Engineering and Sciences (IECBES)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133761835","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Wireless transmission of audio from or to signal processors of cochlear implants can be used to improve speech understanding and localization of CI users. Data compression algorithms can be used to conserve battery power in this wireless transmission. However, very low latency is a strict requirement, limiting severly the available source coding algorithms. Previously, instead of coding the audio, coding of the electrical stimulation patterns of CIs was proposed to optimize the trade-off between bit-rate, latency and quality. In this work, a zero-delay deep autoencoder (DAE) for the coding of the electrical stimulation patters of CIs is proposed. Combining for the first time bayesian optimization with numerical approximated gradients of a nondifferential speech intelligibility measure for CIs, the short-time intelligibility measure (STOI), an optimized DAE architecture was found and trained that achieved equal or superior speech understanding at zero delay, outperforming well-known audio codecs. The DAE achieved reference vocoder STOI scores at 13.5 kbit/s compared to 33.6 kbit/s for Opus and 24.5 kbit/s for AMR-WB.","PeriodicalId":146681,"journal":{"name":"2022 IEEE-EMBS Conference on Biomedical Engineering and Sciences (IECBES)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114553959","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To provide Inhome rehabilitation, it is essential to solve the problem of high rehabilitation cost and improve the rehabilitation efficacy. The training quality assessment is the core part of an in-home based training system as it provides important feedback which can be used by both the doctors and the patients. Furthermore, patients can conduct training in a comfortable, familiar environment. In this paper, a fast-training motion quality evaluation algorithm is proposed for the motion data captured by an accelerometer-based sensor network. The experiment results show that the evaluation result from the proposed system is within a satisfactory error range compared with that obtained by using the commercial X-sens system. The presented fast and efficient quantitative assessment method could be used for implementing a networked regional in-home rehabilitation system covering multiple users.

However, the performance of SERS is highly dependent on the type of SERS substrate used. In this study, solid base SERS substrates are fabricated for detection of low concentration dengue non-structural protein 1 (NS1) in saliva. Using an n-type phosphorous dopant, microstructural porous silicon (PSi) was fabricated using direct current electrochemical method. The PSi was deposited with different sizes of silver nanoparticles (AgNP) to increase the strength of electromagnetic field on the PSi surface. Here, the structural, electrical and Raman characterization of the fabricated AgNP coated PSi are presented. FESEM images show the cross-shaped surface structure of the substrate. The I-V curve reveals that the 75nm-AgNP samples produce better electrical conductivity property than the others. It is also observed that etching longer than a threshold reduces the conductivity performance of the substrate substantially, due to increase in the surface porosity. From Raman spectrum, the silicon peak at 520cm-1 shows a decreasing trend in intensity for samples with 30 min of etching. Interestingly, this observation complements that reported in our previous paper, where etching time of more than 28 min is found not suitable for producing uniform structure of PSi. The consistency between the structural, conductivity and Raman intensity can be used as indicators in developing good SERS substrate for non-invasive detection of low concentration dengue NS1 protein in saliva.","PeriodicalId":146681,"journal":{"name":"2022 IEEE-EMBS Conference on Biomedical Engineering and Sciences (IECBES)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122611746","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study proposed a new segmentation method called gradient-based edge detection with skeletonization (GES), which is specifically designed to segment the optic nerve acquired with T1-weighted magnetization-prepared 180° radio-frequency pulses and rapid gradient-echo (MPRAGE) without fat saturation (FATSAT). GES identifies the edges of the optic nerve based on the largest gradient changes of signal intensity from one region (optic nerve) to another region (CSF). The proposed GES method performed better than the well-known level set method (LSM) with higher Dice similarity coefficient (DSC) of 0.80 - 0.85 compared to 0.61 – 0.77 using LSM. Bicubic interpolation with a factor of 8 was applied before the segmentation process to increase the spatial resolution of the optic nerve. Five datasets of NMOSD patients, clinically diagnosed optic neuritis, were used in this study. The bicubic-GES processed optic nerve images were used for the area and volume measurements on the intraorbital portion of both left and right optic nerves. The measurement results were used to study the effect of Neuromyelitis Optica Spectrum Disorder (NMOSD) on the optic nerve The NMOSD causes optic neuritis and demyelination in the optic nerve.

The gold standard for identifying these heart problems is via electrocardiogram (ECG). The standard 12-lead ECG is widely used in clinical practice and most of the current research. However, using fewer leads can make ECG more pervasive as it can be integrated with portable or wearable devices. This article introduces two novel techniques to improve the performance of the current deep learning system for 3-lead ECG classification, making it comparable with models that are trained using standard 12-lead ECG. Specifically, we propose a multi-task learning scheme in the form of the number of heartbeats regression and an effective mechanism to integrate patient demographic data into the system. With these two advancements, we got classification performance in terms of F1 scores of 0.9796 and 0.8140 on two large-scale ECG datasets, i.e., Chapman and CPSC2018, respectively, which surpassed current state-of-the-art ECG classification methods, even those trained on 12-lead data.
