Ideas for rent: an overview of markets for technology
No full textThis article surveys some of the recent literature on technology markets, and summarizes its main issues and insights. We structure our analysis in three parts: the supply and demand of technology; the factors that condition the formation and growth of technology markets; industry structure and dynamic issues. In addition, we summarize some of the studies that have tried to document the size and growth of these markets. We find that the literature has focused mainly on the supply of technology, but several other aspects of these markets remain under-studied, including the demand for external technology, the role of uncertainty in technology markets, and the dynamic interaction between industry structure and the market for technology. Understanding these will illuminate whether markets for technology will continue to grow or remained confined to pockets of the economy. Copyright 2010 The Author 2010.

Metrics for analytics and visualization of big data with applications to activity recognition
No full textActivity recognition systems detect the hidden actions of an agent from sensor measurements made on the agents' actions and the environmental conditions. For such systems, metrics are important for both performance evaluation and visualization purposes. In this thesis, such metrics are developed and illustrated. For human activity recognition datasets, a reporting structure is described to visualize the metrics in a systematic manner. The other contribution of this thesis is to describe a visualization tool for estimating the orientation (attitude) of a rigid body from streaming motion sensor (accelerometer and gyroscope) data. A feedback particle filter (FPF) is implemented algorithmically to solve the estimation problem.Submission published under a 24 month embargo labeled 'Closed Access', the embargo will last until 2018-05-01The student, Rohan Arora, accepted the attached license on 2016-04-25 at 10:47.The student, Rohan Arora, submitted this Thesis for approval on 2016-04-25 at 10:48.This Thesis was approved for publication on 2016-04-27 at 15:05.DSpace SAF Submission Ingestion Package generated from Vireo submission #9459 on 2016-07-07 at 14:17:57Made available in DSpace on 2016-07-07T21:18:02Z (GMT).

Tibaquira describes the recruitment of and demographics on Hispanic students for cybersecurity education. Arora highlights student demographics, programs, and career outcomes. Brannon explores high school partnerships and engaging new students. The panel members also answer audience questions on engaging Hispanic and underprivileged students, financial solutions, and more.

Role of vitamin D in modulating gestational diabetes
No full textLow maternal levels of major circulating form of vitamin D could be a perplexing factor that leads to
expression of gestational diabetes mellitus (GDM). Insufficient or deficient levels of vitamin D may allow
diabetic insult during pregnancy leading to gestational diabetes and inducing changes in a variety of key
functional molecules and gene expression. Autocrine metabolism of vitamin D promotes anti-inflammatory
response to maternal decidua and fetal trophoblasts. Immunomodulatory actions of vitamin D are likely to
be compromised under conditions of low vitamin D levels with potential detrimental physiological
consequences. Recent data are now available to implicate autocrine/paracrine impact of maternal vitamin
D status can result in both increased insulin resistance and reduced insulin secretion, linking inflammation
to metabolic disorder in the mother. Insulin and cytokines are the main contributors to the cascade of events
and potential regulators of placental function in GDM. This article aims at exploring the possible
mechanisms underlying GDM that could be regulated by pleotropic effects of vitamin D.

цукрового діабету (ГСД). Недостатній рівень або дефіцит вітаміну D може спричинити діабетичний інсульт під час

Аутокринний метаболізм вітаміну D підвищує протизапальну
відповідь на децидуальну оболонку і трофобласт. Імуномодулювальна дія вітаміну D може бути нівельована за умов його
низького рівня і супроводжуватися негативними фізіологічними наслідками. Останні дані демонструють, що ауто- і паракринний вплив вітаміну D у вагітних здатний одночасно підвищувати стійкість до інсуліну і знижувати секрецію останнього, пов’язану із запаленнями та метаболічними розладами у
матері. Інсулін і цитокіни забезпечують основний внесок у каскад подій та виступають потенційними регуляторами плацентарної функції при ГСД. Ця стаття покликана висвітлити
результати вивчення можливих механізмів, що лежать в основі ГСД, які, вірогідно, регулюються плейотропними ефектами вітаміну D.

Towards automated classification of fine-art painting style: a comparative study
No full textThis thesis presents a comparative study of different classification methodologies for the task of fine-art genre classification. The problem of painting classification involves classifying new unknown paintings among different art genres. Two-level comparative study is performed for this classification problem. The first level reviews the performance of discriminative vs. generative models while the second level touches the features aspect of the paintings and compares Semantic-level features vs low-level and intermediate-level features present in the painting. Three models are studied and compared, namely - 1) A Discriminative model using a Bag-of-Words (BoW) approach; 2) A Generative model using BoW; 3) Discriminative model using Semantic-level features. Various experiments and techniques like Bag of Words model, Topic models and Classeme features are employed to get insights into potential of these automatic classification techniques for painting styles.M.S.Includes bibliographical referencesby Ravneet Singh Aror

No full textSynthesis, Characterization and Evaluation of Anticancer Activity of Nanoresveratrol in B16 Melanoma Cell Line
No full textResveratrol, a member of the stilbene family, is a naturally occurring polyphenolic compound in grapes and other botanicals. It carries a potential to prevent or treat several chronic diseases, including cancers. Despite various promising health benefits, including chemopreventive and chemotherapeutic benefits against cancer, clinical translation of resveratrol is hampered due to its poor bioavailability, solubility and stability. Here we present the study to prepare nano-formulation of resveratrol for improving the resveratrol profile. Calcium phosphate loaded nanoresveratrol has been synthesized, characterized and its anti-proliferative effects were examined in a B16 murine melanoma cell line. The anti-cancer effects of nanoresveratrol were directly compared with free resveratrol and chemotherapy drug 5-FU. Nanoresveratrol induced apoptosis in B16 melanoma more efficiently as compared to resveratrol alone and 5 FU. A nuclear staining profile following Hoechst staining of B16 cells is indicative of apoptosis and shows that the anti-cancer effect of nanoresveratrol is due to apoptosis induction. Since antioxidant activity is a hallmark of resveratrol, we also measured the biochemical antioxidant activities of superoxide dismutase (SOD) and catalase antioxidant enzymes. We found that, concurrent with the anti-cancer activity, the antioxidant activity of nanoresveratrol increased. Collectively, these findings clearly show that nanoresveratrol is superior to free resveratrol in suppressing cell growth in B16 murine melanoma cell line, and that the anti-cancer activity is primarily through apoptosis induction.
