Data Driven Safety Feedback as Part of Debrief for General Aviation Pilots
Year: 2019

General Aviation (GA) is the foundation of most flying activities and the training ground for civilian pilots, both recreational and professional. However, the safety record for GA is lacking compared to that of commercial aviation. Approximately 75% of accidents each year involve personnel factors, that is, even if the pilot was not the cause of the accident, they could have done something to either prevent it or improve the outcome. In this research, I aim to improve GA safety through safety driven post flight debrief that encourages pilots to consider the risk in their flights and identify behavioral changes that could make their flying safer. Providing pilots with a debrief tool that they can use with or without a flight instructor requires that we know both what to communicate, and how to communicate it. Risk communication heuristics and biases have not been researched in the context of aviation and flight training and we therefore do not know how pilots understand or respond to debrief. To achieve the goals of this work, I used a three step process: (1) identify events that may put the safe outcome of a flight at risk, (2) detect those events in flight data, and (3) inform the pilot in a way that helps them improve in their future flights. I use a state based representation of historical aviation accidents to define a list of events or behaviors that need to be communicated to the pilots, in the form of states and triggers. I use flight data to retrospectively detect these behaviors upon completion of the flight, by mapping parameters or combinations of parameters that can be calculated and tracked in the flight data to the hazardous states and triggers defined. To present these events to pilots, I created a prototype interactive debrief tool with risk information that I use in a survey to evaluate the effectiveness of feedback in different representation formats. Specifically, I evaluate the impact of three factors: representation method (graphical and numerical) parameter type (safety and performance parameters) and framing language (risk centric and safety centric) I disseminated the survey via aviation mailing lists, type groups, flying clubs, and flight training providers, end received 268 responses. The survey analysis showed that the feedback representation does affect its effectiveness in terms of risk perception, but not when it comes to pilots' motivation to change. The lessons learnt from this survey can be used in creating additional surveys that delve further into risk communication biases and our understanding of how pilots perceive risk and feedback.

A novel sampling moire method and its application for distortion calibration in scanning electron microscope
Year: 2020

High resolution scanning electron microscope (SEM) is widely used for microscale material and structure characterization. However, the distortion in SEM imaging causes serious error for the quantitative measurement of optical methods. In previous work, the distortion calibration requires to set up a mathematic model of SEM imaging and then to determine the model parameters by calculation. The distortion filed is hard to directly extract from the SEM image by classic methods. In order to tackle this problem, we developed a direct sampling moire method (DSM) for simple and fast analysis of grating distortion. In DSM, the distortion fields can be directly presented visually through processing a single grating image. The measurement accuracy of DSM was verified by numerical simulation to be better than the classic sampling moire. In the experiment, a standard grating with pitch of 6.5 mm was used in DSM to calibrate the distortion fields at different magnifications (50 x 100 x 150 x 300 x in SEM. The fitting results of the calibrated distortion field agreed well with the existing distortion model, which demonstrated the feasibility of DSM for distortion calibration in SEM.
Analytical approaches for determination of bromine in sediment core samples by X ray fluorescence spectrometry.
Venue: Talanta
Year: 2016

Bromine has been recognized as a valuable indicator for paleoclimatic studies. Wavelength dispersive X ray fluorescence (WDXRF) and total reflection X ray fluorescence (TXRF) methods were applied to study the bromine distributions in lake sediment cores. Conventional WDXRF technique usually requires relatively large mass of a sediment sample and a set of calibration samples. Some analytical approaches were developed to apply WDXRF to small sediment core samples in the absence of adequate calibration samples with a known Br content. The mass of a sample to be analyzed was reduced up to 200 300mg and the internal standard method with correction using fundamental parameters was developed for Br quantification. TXRF technique based on the direct analysis of a solid suspension using 20mg of sediment sample by internal standard method was additionally tested. The accuracy of the WDXRF and TXRF techniques was assessed by the comparative analysis of reference materials of sediments, soil and biological samples. In general, good agreement was achieved between the reference values and the measured values. The detection limits of Br were 1mg/kg and 0.4mg/kg for WDXRF and TXRF respectively. The results of the Br determination obtained with different XRF techniques were comparable to each other and used for paleoclimatic reconstructions.

A fuzzy inference system is integrated into the model to optimally manage uncertainties related to Time, Quality, Cost, Reliability, and Availability caused by disruptions in the supply chain. The paper illustrates the implication of the model using a simulation in the context of a manufacturing process. The proposed model seeks to satisfy customers' demands for high quality products and services, in a timely manner, at the lowest cost possible. These properties are necessary in times of disruptions such as the COVID 19 pandemic and the like.
Managing Employee Compensation and Benefits for Job Satisfaction in Libraries and Information Centres in Nigeria
Year: 2012

Libraries and Information Centres' services in Nigeria are being regarded as humanitarian services and therefore issue of compensation and benefits are not well defined. However, other forms of financial assistance embedded in the Nigeria civil service rule include things like Monetization, National Health Insurance Scheme, Contributory Pension, and Pension Benefits; all of which staff of Libraries and Information Centres also benefit from. Aside this is the Annual Appraisal Form (Aperform) that contains basic requirements expected of an employee before he can be promoted. Nigerian Universities also makes use of this to assess staff in order to determine their remuneration as at when due.
PO 394 Performance of a targeted T cell receptor beta immune repertoire sequencing panel in several FFPE tissue types a tool for interrogation of the tumour microenvironment
Year: 2018

T cell receptor beta (TCRb) immune repertoire analysis by next generation sequencing is a valuable tool for research studies of the tumour microenvironment and potential immune responses to cancer immunotherapy. Here we describe a TCRb sequencing assay that leverages the low sample input requirements of AmpliSeq library preparation technology to extend the capability of targeted immune repertoire sequencing to include FFPE samples which can often be degraded and in short supply.  This assay targets the highly diverse CDR3 region which allows for T cell clone identification and frequency measurement which, when combined, can provide a broad view of the immune landscape within tissue samples. The assay allows for functionality with either RNA or DNA input, with little modification of the library construction workflow, as well as flexibility in sequencing throughput and sample multiplexing capability. Results and discussions To evaluate assay accuracy, we sequenced libraries including known amounts of 30 well studied T cell lymphoma rearrangements, as well as evaluation of samples comprised of known numbers of sorted T cells to ensure the absence of false rearrangement reporting. T cell repertoires were evaluated from as low as 5 ng to as large as 1 ug of input from samples of varying repertoire diversity, such as sorted T cells, peripheral blood leukocytes, fresh frozen tissue, and FFPE tissue from a variety of normal and cancerous tissues such as lung, colon, brain, spleen, lymph node, and thymus. In parallel, we have developed a low input qPCR assay, based on known T cell markers, which allows for a quantitative measure of the T cell content across all sample types applicable to the TCRb sequencing assay. This sample quantification test acts to guide optimal sample input ranges for library construction and required sequencing depth. Finally, we present the CDR3 TCRb sequencing assay including a dual barcoding approach to extend sensitivity for detection of rare clones.  These data present a T cell immune repertoire sequencing solution for application in a wide range of sample types, in particular, challenging FFPE samples. We find that the assay is capable of profiling repertoire metrics from FFPE samples over a large range of input amounts from several normal and tumour tissue types. In addition, we demonstrate use of a qPCR assay for quantification of sample T cell content to guide sample input for TCRb immune repertoire sequencing experiments.
Ratiometric fluorescence sensors for heparin and heparinase based on enhanced excimer emission of perylene probe induced by cationic silver nanoparticles
Year: 2020

Herein, cationic MUTAB Ag NPs of different sizes were synthesized and their interactions with a negatively charged perylene probe, N,N' bis(6 caproic acid) 3,4:9,10 perylenediimide (PDI COOH) were investigated.  Ag NPs could result in significant monomer quenching and excimer formation by inducing probe aggregation due to the strong electrostatic attractive interactions between them. Moreover, significant excimer emission could be observed at extremely low probe concentration when induced by larger MUTAB Ag NPs. A possible mechanism of metal enhanced fluorescence was proposed, which is evidenced by the strong dependence between surface plasmon resonance absorption spectra of MUTAB Ag NPs and the excimer emission spectra of PDI COOH, together with the sharp decrease in fluorescence lifetime of excimer compared with that induced by poly(allylamine) Consequently, ratiometric fluorescence sensors for heparin and heparinase were developed based on the Ag NP induced excimer emission of PDI COOH. The adsorption of heparin on the surface of MUTAB Ag NPs led to the release of monomer, while the degradation of heparin by heparinase facilitated the formation of PDI COOH excimer. The monomer excimer transition signal was harnessed for heparin and heparinase sensing, which exhibited good sensitivity and excellent selectivity. Finally, application of the present system for detection of heparin and heparinase in human serum sample was successfully demonstrated.
The medicinal mushroom Auricularia auricula judae (Bull. extract has antioxidant activity and promotes procollagen biosynthesis in HaCaT cells
Venue: Natural product research
Year: 2018

In this study, Auricularia auricula judae (Bull. extract (AAE) had potent antioxidant activity in vitro and promoted the biosynthesis of procollagen, a precursor of collagen in HaCaT cells. In addition, the expression of HAS 3 (hyaluronic acid synthase) which is a moisturizing factor, was increased in HaCaT cells in response to AAE. Therefore, this work suggests that AAE has the potential to exhibit antioxidant activity and promote procollagen biosynthesis in HaCaT cells.
Retrieval of brain MRI with tumor using contrastive loss based similarity on GoogLeNet encodings
Venue: Comput. Biol. Medicine
Year: 2020

An image retrieval system for medical images aids in disease diagnosis by providing similar images from the medical database to a query image. In this article, a content based medical image retrieval (CBMIR) system is proposed for the retrieval of magnetic resonance imaging (MRI) images of the brain with three types of tumors: meningioma, glioma and pituitary tumors. The proposed system uses GoogLeNet encodings via transfer learning as image features. A Siamese Neural Network (SNN) is designed, to represent the GoogLeNet encodings in a two dimensional (2 D) feature space. The SNN is trained using the contrastive loss function to learn the class specific image features. The similarity, between a query image and the database images, is measured by the Euclidean metric in the lower dimensional feature space. The proposed method achieves state of the art performance for the retrieval of MRI images with brain tumors. The evaluation is done on the openly available Figshare dataset and the performance metrics used are mean average precision (mAP) and precision@10.
Determinants of the property assessment uniformity
Year: 2013

As Lithuania ponders the adoption of the universal property tax on real estate, the advantages and disadvantages of property taxation are discussed in media and scholarly articles. At the heart of the property tax, there is the need for assessment, the determination of property value for taxation purposes. The importance of assessment for the equitable distribution of the total tax burden does not receive enough emphasis in research. This article attempts to fill in this gap by testing an empirical model based on the data from the USA, a country, where property taxation has a long history. The model tests what factors are contributing to the variation of the coefficient of dispersion (COD) an internationally recognized measure of assessment uniformity. The results of the analysis indicate that the economic structure and housing market conditions are the most important determinants of the property assessment uniformity, while variables related to the location of property and the level of taxation do not have a significant impact on assessment uniformity.
Modulation of the combinatorial code of odorant receptor response patterns in odorant mixtures
Venue: Molecular and Cellular Neuroscience
Year: 2020

The perception of odors relies on combinatorial codes consisting of odorant receptor (OR) response patterns to encode odor identity. Modulation of these patterns by odorant interactions at ORs potentially explains several olfactory phenomena: mixture suppression, unpredictable sensory outcomes, and the perception of odorant mixtures as unique objects. We determined OR response patterns to 4 odorants and 3 binary mixtures in vivo in mice, identifying 30 responsive ORs. These patterns typically had a few strongly responsive ORs and a greater number of weakly responsive ORs. ORs responsive to an odorant were often unrelated sequences distributed across several OR subfamilies. Mixture responses predicted pharmacological interactions between odorants, which were tested in vitro by heterologous expression of ORs in cultured cells, providing independent evidence confirming odorant agonists for 13 ORs and identifying both suppressive and additive effects. This included 11 instances of antagonism of ORs by an odorant, 1 instance of additive responses to a binary mixture, 1 instance of suppression of a strong agonist by a weak agonist, and the discovery of an inverse agonist for an OR. Interactions between odorants at ORs are common and in some cases correlate with the ability to perceive an odorant in a mixture.
Classifying Documents within Multiple Hierarchical Datasets Using Multi task Learning
Venue: 2013 IEEE 25th International Conference on Tools with Artificial Intelligence
Year: 2013

Multi task learning (MTL) is a supervised learning paradigm in which the prediction models for several related tasks are learned jointly to achieve better generalization performance. When there are only a few training examples per task, MTL considerably outperforms the traditional Single task learning (STL) in terms of prediction accuracy. In this work we develop an MTL based approach for classifying documents that are archived within dual concept hierarchies, namely, DMOZ and Wikipedia. We solve the multi class classification problem by defining one versus rest binary classification tasks for each of the different classes across the two hierarchical datasets. Instead of learning a linear discriminant for each of the different tasks independently, we use a MTL approach with relationships between the different tasks across the datasets established using the non parametric, lazy, nearest neighbor approach. We also develop and evaluate a transfer learning (TL) approach and compare the MTL (and TL) methods against the standard single task learning and semi supervised learning approaches. Our empirical results demonstrate the strength of our developed methods that show an improvement especially when there are fewer number of training examples per classification task.
SHARONLAY: A new approach for post endodontic restorations: A Case Report
Year: 2020

Root canal treatment leads to a considerable loss of tooth structure so after completion of root canal treatment it should ideally be followed by a restoration that allows cuspal coverage. This is important as there is a direct relationship between the amount of remaining tooth structure and the ability to resist occlusal forces. The cuspal width to length ratio of 1:2 or more decides whether there is a requirement of a full crown or an onlay. SHARONLAY is a new onlay design providing the necessary reinforcement in a conservative manner and protecting endodontically treated teeth against both vertical and horizontal forces. This case report presents the use of SHARONLAY as a possible alternative for post endodontic restorations.
Flavonoids in Cancer and Apoptosis
Venue: Cancers
Year: 2018

Cancer is the second leading cause of death globally. Although, there are many different approaches to cancer treatment, they are often painful due to adverse side effects and are sometimes ineffective due to increasing resistance to classical anti cancer drugs or radiation therapy. Targeting delayed/inhibited apoptosis is a major approach in cancer treatment and a highly active area of research. Plant derived natural compounds are of major interest due to their high bioavailability, safety, minimal side effects and, most importantly, cost effectiveness. Flavonoids have gained importance as anti cancer agents and have shown great potential as cytotoxic anti cancer agents promoting apoptosis in cancer cells. In this review, a summary of flavonoids and their effectiveness in cancer treatment targeting apoptosis has been discussed.
Les mobilisations socio territoriales le Larzac, une cause en mouvement
Year: 2009

Le 12 aout 1999, des syndicalistes paysans demontaient le chantier d'un McDonald's en construction a Millau, dans l'Aveyron. Co organisateur de cette action,  Bove se voyait des lors reconnaitre comme un des leaders de l'altermondialisme, mobilisation qui commencait a se developper en France. A travers celui qui etait alors un des animateurs du Syndicat des producteurs de lait de brebis (SPLB) et de la Confederation paysanne, le Larzac revenait sur le devant de la scene politique et sociale, pres de trente ans apres le debut de l'opposition des paysans concernes par le projet d'extension d'un camp militaire sur le plateau du Larzac. Territoire montagneux du sud de la France, paysage de causse austere au climat hostile, le Larzac avait alors constitue le creuset de tout ce que la France comptait de protestataires engages dans les luttes antimilitaristes, antinucleaires, autogestionnaires ou encore regionalistes. Des lors la question se posait de comprendre pourquoi le Larzac avait pu generer, a des moments differents, des mobilisations socio territoriales et se voir conferer le statut de point de passage oblige des mouvements protestataires se referant a cette lutte paysanne initiale, ou la tenant pour modele. Cette these vise a expliciter les logiques, les formes et les processus des mobilisations qui se sont developpees dans le sillage de ce lieu nodal et strategique de confluences de causes et de debats. A partir d'une enquete sur les luttes que le Larzac a connues depuis les annees soixante dix, de leurs actualisations successives, de leurs moments forts, de leur sedimentation organisationnelle (associative et syndicale) ce travail montre que le Larzac doit etre considere comme un site protestataire iteratif charge d'experiences militantes et investi de valeurs specifiques comme celle de l'authenticite. L'analyse des strategies discursives des acteurs du Larzac met en exergue un double mecanisme d'appropriation physique et rhetorique des lieux, au terme duquel le Larzac est erige en haut lieu, ou lieu pour l'exemple de la protestation. Aussi la dimension territoriale occupe t elle une place a la fois identitaire et instrumentale. L'analyse des bonnes raisons de ces luttes, de leur repertoire d'action, des strategies connexionnistes qu'elles operent permettent de reflechir sur les dimensions de la construction des problemes publics (OGM) ainsi que sur les investissements modalises par le militantisme socio territorial.
