The experiment was conducted on a high fidelity driving simulator. Three different scenarios were designed to investigate the driver's state during normally driving (braking and accelerating) and turning (left or right). In the daily-urban scenario, a deer collision occurred. During each driving trial, the EEG signal was recorded by a 32-lead system. The EEG dynamics were analyzed using power spectrum density (PSD), event-related potential (ERP), independent component analysis (ICA) and time-frequency analysis (TFA). In normally driving, the EEG responses are similar during the three different scenarios. The power concentrates on the frontal and back lobes. During turning, the EEG response is somehow different from that in normally driving (only braking and accelerating). In the deer-collision event, a rapid response is apparent in the ERP mapping.","PeriodicalId":153112,"journal":{"name":"2013 39th Annual Northeast Bioengineering Conference","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128011795","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 disease has become a national epidemic in the United States, and therapy non-adherence has become one of the largest precursors leading to diabetic sequelae such as diabetic ketoacidosis. A potential source of patient therapy negligence is the discomfort associated with the finger prick method of glucose monitoring. As a result, a less invasive method to monitor diabetes is sought. This paper describes a portable breathalyzer that is being developed to monitor acetone in the breath of a diabetic patient. The proposed design aims to eliminate the finger prick through a simplified approach for monitoring acetone levels in correlation to elevated glucose levels, thus determining the onset of diabetic ketoacidosis.","PeriodicalId":153112,"journal":{"name":"2013 39th Annual Northeast Bioengineering Conference","volume":"155 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123452163","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}

Existing respiration monitors used in medical centers are too expensive to be used in low-resource environments. We have developed a low-cost respiratory monitor to address this issue. This device calculates a patient's breathing rate by detecting changes in temperature through a thermistor when the patient breathes in a mask. Features of the device include an alarm through a piezoelectric speaker which sounds when the patient stops breathing and a low-battery indicator signal for when the battery powering the device dips below a threshold voltage. The design and implementation involved several different hardware components, as well as software functions. Our initial prototype of our project accomplished our main objectives, and experimental measurements indicate that the device measures a person's respiration rate with relative accuracy.","PeriodicalId":153112,"journal":{"name":"2013 39th Annual Northeast Bioengineering Conference","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115592969","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}

Hydrogels can be modified to optimize their rheological and mechanical properties for improved bone formation and vascularization at defect sites. Hydrogels are a type of hydrated polymeric materials with properties similar to those of natural tissue as a result of their ample water constituents. The hydrogels used in this study were modified derivatives of methylcellulose, agarose, and chitosan blends capable of rapid transition from sols to gels [Zuidema 2011]. A natural chemical compound, genipin, was added to induce cross-linking in the chitosan component of the hydrogels. The added control of cross-linking enabled the increased manipulation of hydrogel stiffness without alterations in polysaccharide constituents. The ability to create multiple hydrogels with varying stiffness allowed for the determination of an optimal hydrogel stiffness for the support of mineralization and vascularization in bone defects. Hydrogel stiffness is an essential factor in cell adhesion and function, with low-stiffness gels favoring vascularization and high-stiffness gels favoring mineralization. This study aimed to determine an optimal gel stiffness that could promote both mineralization and vascularization to encourage the formation of healthy mineralized bone in defect sites. In addition, the inherent anti-bacterial efficacy of the hydrogels was evaluated as it pertained to the issue of sterilization in bone defects. In this study, we designed multifunctional hydrogels with varied stiffness and assessed their anti-bacterial efficacy and ability to promote mineralization and vascularization for eventual use in bone defect healing.","PeriodicalId":153112,"journal":{"name":"2013 39th Annual Northeast Bioengineering Conference","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122330275","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}

Researchers in bioinformatics field are expecting faster and more accurate tools to effectively analyze the gigantic data sets. In the context of aptamer search, the goal is to search for the over-represented DNA sequences compared with random background libraries on the same chip. Hash functions are widely used in substring comparison, sequence alignment and clustering tools. We have developed a light-weighted tool that takes advantage of the hash functions to reduce the size of genomic data and conducts k-neighbor searches on the centroid sequence. This greatly improves the efficiency of the search compared with the existing tool. Furthermore, the calculation of k-neighbor hash values decreases the mutant searching overhead. In a dataset of 1 million sequences, the program accurately counted the frequency of the Human alpha-Thrombin sequence and found the mutant versions of the target sequence in less than 40 seconds, whereas the existing method takes 8280 seconds (2 hours 13 minutes).","PeriodicalId":153112,"journal":{"name":"2013 39th Annual Northeast Bioengineering Conference","volume":"133 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122406367","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}
