Applications of machine learning in biophotonics and laser metrology
No full textRecently, optical technologies have found several applications in fields including biophotonics, precision metrology and wavelength scale sensors. However, to gather statistically relevant information and analysis these methods require large amount of measurements. Current linear multivariate methods such as principal component analysis or linear discriminant analysis are not sufficient to analyze these big datasets with non-linear variability. Recently, the application of deep learning based artificial neural networks have found an upsurge in various areas of science ranging from quantum physics to evolutionary biology, providing an enhancement in the efficiency of various techniques. This thesis focuses on the applications of machine learning with the goal to enhance different aspects of biophotonics.
Firstly, this thesis explores the application machine learning to enhance the label-free characterization of cells of the immune system using Raman spectroscopy and digital holographic microscopy. The combination of deep learning with digital holographic microscopy provides a route towards a high throughput hemogram device which would be useful for the classification of clinically important immune cells with morphological similarities but different functions.
Following this, the applications of deep learning are explored in the regime of precision optical metrology for the development of a laser speckle wavemeter with a high dynamic range with an additional application for the development of a binary speckle based spectrometer.
Finally, the application of machine learning based methods are also explored to improve the sensitivity of the chirped guided mode biosensor. A comparison between the linear method of principal component analysis and direct Fano fitting is drawn which is followed by the application of multi layered perceptron for further improvement."This work was supported by Medical Research Scotland [Grant Ph.D. 873-2015],

Introduction of 'patient safety' module to undergraduate medical students through an interactive workshop
No full textBackground: The World Health Organization (WHO) had developed a curriculum guide designed to shape foundation knowledge and skills of medical students to sensitise them regarding 'Patient Safety'. 'Patient Safety' is not emphasised in the current undergraduate (UG) medical curriculum. This study is an attempt to know the effectiveness of introducing a 'Patient Safety' Module based on the WHO's proposed curriculum, through an interactive workshop for UG medical students.
Methods: This cross-sectional study was conducted with 77 students of 2nd year Bachelor of Medicine, Bachelor of Surgery (MBBS). Three topics of the WHO's 'Patient Safety Curriculum' were taught through an 'Interactive workshop' and a study tool, comprising of multiple-choice question and Likert scale. A questionnaire was also administered pre- and post-workshop, followed by a 'field activity' which allowed students to apply their newly learnt knowledge in a real hospital setting. Feedback was taken and qualitatively analysed.
Results: The mean score of first section of the study tool was 9.2 (45.9%) in pre-test and 14.6 (73.2%) in post-test, with a positive difference of 5.5 (27.4%) marks. The analysis of section 2 showed a significant positive change in the knowledge level, but a non-significant change was noted for the level of agreement, own ability to influence, personal attitudes with regard to patient safety and expectations about patient care. Overall analysis of the second section revealed a significant change to the positive side.
Conclusions: 'Interactive Workshop' significantly increased the knowledge regarding patient safety, and therefore, it is an effective method to teach 'patient Safety' to UG medical students
A prospective study of incidence and risk factors for secondary glaucoma after penetrating keratoplasty
No full textAim: To carry out a prospective study to analyze the incidence and risk factors for secondary glaucoma after penetrating keratoplasty (PK). Materials and Methods: Three hundred and eleven consecutive penetrating keratoplasties that were performed between January 1, 2006, and December 31, 2008, with a follow-up of 12 months were prospectively analyzed to determine the factors associated with postoperative glaucoma. Results: Of 311 eyes, secondary glaucoma developed in 57 cases. This yields an incidence of 18.3%. In conditions, such as aphakic bullous keratopathy, the incidence of post-PK glaucoma was 3.0%; in pseudophakic bullous keratopathy 14.0%, and in cases of failed graft 16.0%, while in cases of corneal ulcer and corneal opacity it was 49.0% and 18.0%, respectively. Conclusion: We conclude in our study that the incidence of glaucoma developing post-PK was highest in phakic eyes, which may be due to the formation of posterior synechiae and development of intumescent cataract. Higher incidence of glaucoma developing in infective cases could be due to recipient hot eye and the high incidence in cases of large graft could be attributed to the formation of peripheral anterior synechiae

The ‘biobibliometrics’ term is used for a method of retrieving and visualizing biological information that uses co-occurrence of gene naming terms in Medical Sciences to generate semantic links between genes. Therefore it is suggested that ‘Scientometric Portrait’ is the appropriate phrase for the studies on scientists and ‘Informetric Portrait’ for the studies pertaining to researchers in other disciplines such as arts, humanities, and social sciences
Lasers in medical applications: R&D Mapping
No full textA study of the MEDLINE CDROM database, for the period 1969-2000 was undertaken. The purpose was, to identify core areas of research and development, in the field of applications of lasers to humans, along with other bibliometric indicators of research. A total of 34,833 records were retrieved, downloaded and analysed. The results
indicate a steady increase in the number of publications every year, from 1970 onwards, with 1997 (2767 articles) and 1998 (2914 articles) being the most productive years. The most prolific contributors were J. Haut, with 95 publications to his credit, followed by M. Landthaler (82), G. Coscas (79), S.G. Bown (73) and P. Bjerring (70). Collaboration among the authors was high, with a maximum of 15 contributors observed in a few articles. The top ranking journal in the field was Ophthalmology, which published 769 articles starting from 1978. USA was way ahead as the country with the highest journal productivity (around 40% of the total number of records), followed by UK and Germany.
A total of 103 articles were published from India. English was the preferred language of publication, with 75% of the records being published in English language. In the use of
lasers for humans, maximum number of records were found for adult and middle aged populations. Research focussed on the eye and its various diseases. Lasers were found to
be used for therapeutic purposes, in surgery and in the diagnosis of diseases. Carbondioxide laser was most frequently used for medical applications. Though there
were quite a few references on the adverse effects of lasers, the therapeutic effects far outweighed them
