Polarization is a property of light waves that describes the orientation and shape of their oscillations. The polarization state can be described using Stokes parameters, and several measurements derived from these parameters such as the degree of polarization, the azimuth and ellipticity angles of the polarization ellipse, and the coordinates on a Poincaré sphere. The probe shines low-intensity polarization-controlled laser light at a lesion, and analyzes the backscattered light in order to detect how the light's polarization has been changed due to the light-tissue interaction. Testing with skin phantoms has demonstrated a relationship between phantom roughness and the degree of polarization. Preliminary testing on an in-vivo lesion showed that lesion sites demonstrated a lower degree of polarization as compared to normal skin. These results indicate our progress towards the development of a powerful and practical tool to assist skin lesion evaluation.","PeriodicalId":361773,"journal":{"name":"2016 IEEE EMBS International Student Conference (ISC)","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126249548","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}

The aim of the model is to provide brain-computer interfaces with improved cursor control without the need for a separate eye tracking device. To test the accuracy of the model \"in-the-wild,\" an EEG dataset with (uncontrolled) natural saccades was used, where subjects looked freely at images on a screen. EEG data was input to deep neural networks, namely a multi-layer perceptron and a convolutional neural network. As benchmarks, two systems were explored using features measured from the Fp1/2 EEG channels, as well as from the AF7/8, F7/8, FT7/8, and T7/8 channels. Experimental results show the proposed system achieving an accuracy of 72.92%, thus outperforming all benchmarks, which achieved accuracies of 51.80% and 50.72%, respectively.","PeriodicalId":361773,"journal":{"name":"2016 IEEE EMBS International Student Conference (ISC)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134264721","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}

Accelerometer and gyroscope signals did not correlate well between the two locations. Important gait parameters at the wrist may lead to a better understanding of human locomotion profile due to periodic trends observed in wrist data. Turn detection accuracy was 86.0±23.1% and 78.3±20.2% for the MSB2 and smartphone, respectively. Turn detection showed that the smartphone y-axis gyroscope had more distinct peaks.

Surgical intervention involves a pull-through operation, connecting ganglionic segments together after excising the aganglionic segment. Subjective examination of seromuscular biopsies and resected segment for ganglion cells by a pathologist is the standard of care for Hirschsprung's patients. This paper explores the feasibility of an objective approach using multistage color image processing to segment the muscularis propria, identify regions of interest within, separate plexuses in the regions of interest, and detect and quantify ganglion cells within individual plexuses. Results observed on one test case showed that this multistage approach was able to segment muscularis propria with results comparable to manual segmentation at 77.3% region-coincidence. Regions of interest were identified with 100% accuracy, all containing at least one plexus, with 0 false negatives. Automatic plexus segmentation had a precision of 88.5% and recall of 90.2%. Automated ganglion detection achieving a precision of 85.7% and recall of 72.0%. Preliminary results are encouraging but performance needs improvement. The main issues encountered is the varying colour contrast within an image and the use of an imperfect feature set for classification.","PeriodicalId":361773,"journal":{"name":"2016 IEEE EMBS International Student Conference (ISC)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131301394","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 produce a given body movement, a group of muscles are usually acting in a synergic fashion. It is possible that information about a movement could also be extracted from an individual muscle within a synergic group. Physiologically, the large biceps brachii (BB) muscle is involved in forearm flexion and hand supination and also contributes to raising the arm forward and upward. For the BB, synergy can originate from its different compartments and their contribution identified with a decomposition algorithm applied on signals recorded over its surface. Here, the synergy extracted from 3 signals collected over the BB were used to control one degree of freedom (DoF) of the shoulder, elbow, and wrist joints of a dextrous humanoid arm manipulator. Synergy information could thus be useful for helping an upper-limb amputee person to control a modern myoelectric prosthesis.","PeriodicalId":361773,"journal":{"name":"2016 IEEE EMBS International Student Conference (ISC)","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133007637","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}

Thus, this study evaluated that the micro-current electrical treatment (MET) can reduce rheumatoid arthritis (RA), which is one of inflammatory disease, and tried to find optimized level of current for treatment. 55 male 11-week-old C57BL/6 mice were used and randomly allocated into five groups; normal group (N; n=11), the group of induced RA (C; n=11) and three groups of induced RA with MET (M) using different levels of current by 22 μA, 50 μA, and 400 μA (22M, 50M and 400M; n=11, respectively). MET was carried out for 1 hour each day. Both 3rd metatarsal (3rd MT) and tarsal (T) were scanned by in-vivo micro computed tomography (micro-CT) at 0week and after 3weeks in order to obtain structural parameters including BMD (Bone mineral density), BV (Bone volume) and Obj.N (Mean number of objects per slice). In M groups, all the measured parameters after 3 weeks were significantly higher than those of C group regardless of the current levels. However, there is no significant difference among the different levels of electrical current at 3week. These results indicated that the MET may be effective on the treatment of RA. However, we cannot assure the optimized level of current to treat RA tremendously.","PeriodicalId":361773,"journal":{"name":"2016 IEEE EMBS International Student Conference (ISC)","volume":"142 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123427004","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}
