Various machine learning models have been developed for AB detection, however studies regarding the data structures used for model training are scarce. This study investigates the effects of different training data structures and sizes of Convolutional Neural Networks (CNN) to detect AB. Four CNN models were developed using different amounts of data and data structures: one-dimension, line, area, and array. Training datasets consisting of 300, 1,000, 5,000 and 10,000 airway pressure waveforms from MV patients were used for model development. Model sensitivity and specificity were evaluated using an independent set of 3000 waveforms in a 100-iteration Monte-Carlo analysis. The best-performing CNN model was used to determine Asynchrony Index (AI) values in a clinical patient cohort. Monte-Carlo analysis showed that models trained with datasets of 10,000 breathing cycles delivered $gt99$% sensitivity and specificity. Relatively lower sensitivity and specificity of $lt78.8$% and $lt96.7$% respectively were obtained when trained with data quantities of 5000 breaths or less. A CNN trained with 1Dimensional data structure yielded 99.9% sensitivity and 99.6% specificity. It achieved 88.5% average accuracy when validated with an independent clinical data set of 544,319 breaths. Asynchrony breathing detection is ubiquitous and 1-Dimensional data structures provide a resource efficient method for the development of an accurate CNN model.","PeriodicalId":146681,"journal":{"name":"2022 IEEE-EMBS Conference on Biomedical Engineering and Sciences (IECBES)","volume":"50 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":"122926909","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}

These developments have enabled us to gain an unprecedentedly detailed insight into brain activity by analyzing brain imaging data, which will reshape our understanding of brain activity and uncover biomarkers of brain disease.Over the past decade, the analysis of resting-state functional connectivity has become a trend because brain connectivity provides an effective way to understand how spatially distant brain regions interact and achieve coherent neural functions. One of the most common approaches to analyze functional connectivity is the Pearson correlation. This paper uses a new correlation method to calculate functional connectivity: Spearman’s rank correlation. We apply two conventional machine learning methods to classify autism spectrum disorder (ASD) patients from typically developing (TD) participants based on functional connectivity derived from resting-state functional magnetic resonance imaging (fMRI) data. To verify the feasibility and validity of Spearman’s rank correlation in the classification of autism, we compared the accuracy, sensitivity, and specificity of methods using functional connectivity obtained from Pearson’s correlation and Spearman’s rank correlation. Moreover, feature selection is one of the essential tasks in classification studies. We present an empirical comparison of two feature selection methods: select from model (SFM) and recursive feature elimination (RFE).","PeriodicalId":146681,"journal":{"name":"2022 IEEE-EMBS Conference on Biomedical Engineering and Sciences (IECBES)","volume":"82 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":"114493463","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}

In order to gain further insight into the underlying disease mechanisms, animal models are used. However, the most critical obstacle for further research is the lack of subcutaneous implantable, miniaturized neurostimulators that can deliver reliable and replicable results. Extracorporeal mounting of neurostimulators on the head or back places a high burden on the animal. Furthermore, the animals frequently tamper with these stimulation setups, leading to high failure rates. In the absence of suitable diagnostic tests, such defects generally escape detection. Therefore, this article presents strategies for a DBS stimulator design intending to increase the scientific merit of behavioral experiments in rodents. In this context, we demonstrate an easy-to-implement, waterproof, biocompatible, and compact encapsulation method suited for full implantation in small rodents. Using this method, we implanted DBS devices subcutaneously in dystonic hamsters that have been successfully tested for up to 17 days.","PeriodicalId":146681,"journal":{"name":"2022 IEEE-EMBS Conference on Biomedical Engineering and Sciences (IECBES)","volume":"9 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":"123946649","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}

Reactive nitrogen and oxygen species in the plasma play a vital role in this process. The concentration of these radicals is dependent on the plasma’s operating conditions (e.g. applied voltage and gas flow rates). Radicals’ vibrational and rotational temperatures play a vital role in wound healing and are required to find an optimized plasma operating condition for the wound healing process. The current project aims to measure the plasma temperatures (vibrational, rotational, and electronic) for a multi-electrode torch. The emission spectrum for various electrodes of the plasma torch was captured at various operating conditions. For this purpose, an Ocean Optics UV-IR spectrometer in conjunction with SPECAIR was used to estimate the vibrational, rotational, and electronic temperatures of the plasma. For this experiment the multi-electrode plasma torch was operated at various conditions by changing the outer electrodes, gas flow rates (helium 20-40 slpm), and input applied voltages (5kV-10kV and 20-40 kHZ). Experimental results reveal that both plasma vibrational and rotational temperatures $(sim 500mathrm{K}700mathrm{K})$ were dependent on the measuring position from the plasma exit at identical operating conditions. No significant change in electronic temperatures $(sim 2800mathrm{K}$ – 3000K) was observed for all conditions. Detailed results are included in this paper.","PeriodicalId":146681,"journal":{"name":"2022 IEEE-EMBS Conference on Biomedical Engineering and Sciences (IECBES)","volume":"55 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":"127925115","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}
