    Information retrieval is one of the most challenging tasks for the mankind and to retrieve information interaction is required, which ultimately leads to the formation of networks. Universe is packed with different type of networks. Networks with complex topological properties are called complex network. Such types of networks are major tools for learning the connection between the organizations and finding the purpose of complex systems. The link prediction problems in complex networks facilitate predictions about the future organization of the network. Network is represented as a graph. The data in the network is signified by nodes, and the relations are represented by links. The future of non-connected links amid node pairs is predicted. This paper reviews the methods used to predict links for complex networks using similarity-based heuristics. Previous reviews, despite having a clear outline of the link prediction study, only described the prediction approaches. Research gaps between the similarity-based link prediction techniques, however, were not explicitly stated. With the help of chronological findings and a research gaps approach, this review seeks to give a continuing review and introduce the link prediction

    Primary Small Cell Carcinoma of the Larynx: Report of a Rare Tumor

    Get PDF
    Primary small cell carcinoma of larynx is a rare tumor representing less than 0.5% of all laryngeal cancers. This is one of the most lethal of all malignancies associated with frequent early widespread metastases and dismal prognosis. We report a case of a 60-year-old patient with small cell carcinoma of the subglottic larynx, who presented with hepatic metastasis

    Falling Prices: Does This Cause Purchases to Be Delayed or Speed Up? Evidence From the Gasoline Market

    When teaching macroeconomics, students intuitively know why macroeconomists stress the dangers of inflation, but question why economists will say deflation is worse. To explain macroeconomists will almost always point to Japan’s “Lost decade”, a spiral of declining economic activity intertwined with declining prices. Their claim is that the deflation was a principle driver for the deepening recession as declining prices could cause consumers not to purchase more (as the law of demand would normally expect) but rather less in anticipation of even lower prices to come. This paper looked at the empirical evidence from the energy sector, specifically gasoline sales during the 2013-2015 time period and verified that there is evidence that some US consumers did indeed delay purchases even if they ultimately bought more

    Thermal Energy Storage and Management in Water-based Trombe Walls

    Trombe walls use solar energy to reduce energy consumption in buildings. However, Trombe walls can cause overheating during summer. The objective of this thesis is to design aesthetically pleasing Trombe walls that use solar energy for space and water heating more effectively. The water-based Trombe wall design consists of a semi-transparent sheet that absorbs sunlight which is immersed in water. Results from performing simulations and lab-scale experiments show that water-based Trombe walls can reduce building heating loads to the same extent as conventional Trombe walls during winter months. Furthermore, to prevent overheating during summer, heated water extracted from the top of the Trombe wall can be used as pre-heated water and supplied to a hot water tank. Results show the Trombe walls designs proposed in this research can produce 3.5 times more than the amount of heated water required during summer in an average household in Toronto, Canada

    Smart Breeding for Climate Resilient Agriculture

    Human society is at a turning point of its time as climate change is becoming more and more real and inevitable. From rising temperature, which undermines the food production, to melting glaciers, causing disastrous flooding and erosion, the global repercussions of climate change are unprecedented. Plant breeding has always played a pivotal role in human history by revolutionizing agriculture to feed the ever-growing population. It can rescue humankind from imminent threats to agriculture posed by weather fluctuations, rapidly evolving pests and limiting resources. Unlocking the repository of genetic diversity and extensive utilization of wild germplasm invariably is imperative to every crop improvement program. But recent advancements in genomics, high throughput phenomics, sequencing and breeding methodologies along with state-of-the-art genome-editing tools in integration with artificial intelligence open up new doors for accelerated climate-resilient crop improvement. Therefore, holistic smart breeding approaches can be promising way out to tackle climate change and develop better-adapted crop varieties

    Pattern of anti-diabetic drugs prescribed for type 2 diabetes mellitus patients in a tertiary care hospital of India: an observational study

    Get PDF
    Background: Type 2 diabetes mellitus (T2DM) is a leading cause of significant morbidity and mortality in developing countries. Evaluation of anti-diabetic drug use pattern guides the healthcare professionals to identify early signals of irrational prescribing and to plan interventions to optimize the benefits of pharmacotherapy.Methods: Observational descriptive study was conducted on 500 prescriptions of T2DM patients collected from Outpatient department of a tertiary care hospital. Prescriptions were analysed for type, number, generic/brand names, fixed dose combinations (FDCs) of anti-diabetic drugs and anti-diabetic drugs prescribed from within National List of Essential Medicines (NLEM) 2015.Results: Average number of anti-diabetic drugs per prescription was 2.5. Of these 49% were from within NLEM and only 39% were prescribed by their generic names. Among all the anti-diabetic groups of drugs used, biguanide (32.85%) was the most frequently prescribed followed by insulins (25.4%) and DPP-4 inhibitors (13.75%). Combined drug therapy was more prevalent than monotherapy (70% versus 30%). Metformin+sitagliptin and metformin+linagliptin were most commonly prescribed fixed dose combinations.Conclusions: Recent trend of anti-diabetic drug use included newer anti-diabetic drugs in combination with metformin to achieve better euglycemia and to minimize complications of T2DM

    The Impact of University Student Services and Student Life Characteristics on Students’ Perceptions of Online Education

    Student support services and student life have been an integral part of most institutions of higher education for decades. Academic advising, registration coordination, formal tutoring, and informal study groups are some of the more important venues that support academic success. This research fills in a critical gap in the higher education literature by reporting on how six university student support services and six student life characteristics impacted student perceptions of academic success in the online environment. The findings also document students perceived ability to move to the online platform, satisfaction with the online learning experience, and willingness to take future online courses by surveying business students at a comprehensive, AACSB-accredited business school. The results indicate a positive impact of services offered by the Academic Advising Office, Registrar’s Office, and the Writing Center whereas a lukewarm response to the Tutoring Center and Peer Mentoring support services. Among student life attributes, campus technology solutions were most helpful to students in achieving their academic goals
