Closure of Universities Due to Coronavirus Disease 2019 (COVID 19) Impact on Education and Mental Health of Students and Academic Staff
Venue: Cureus
Year: 2020

The novel coronavirus disease 2019 (COVID 19) originated in Wuhan city of China, has spread rapidly around the world, sending billions of people into lockdown. The World Health Organization (WHO) declared the coronavirus epidemic a pandemic. In light of rising concern about the current COVID 19 pandemic, a growing number of universities across the world have either postponed or canceled all campus events such as workshops, conferences, sports, and other activities. Universities are taking intensive measures to prevent and protect all students and staff members from the highly infectious disease. Faculty members are already in the process of transitioning to online teaching platforms. In this review, the author will highlight the potential impact of the terrible COVID 19 outbreak on the education and mental health of students and academic staff.
Phrasal compounds can have adjectival heads: evidence from English
Venue: English Language and Linguistics
Year: 2020

Phrasal compounds are taken to be word level structures that combine a lexical head with a phrasal non head. Several claims have emerged from the pertinent literature: phrasal compounds allegedly only have nominal heads, can host a variety of syntactic structures in non head position, are determinative, and are instances of expressive morphology. The existence of adjectival phrasal compounds is either explicitly denied in the literature, or considered a marginal phenomenon at best. This article presents data from the Corpus of Contemporary American English (COCA; Davies 2008) that show that adjectival phrasal compounds do exist in English. We demonstrate that they are similar to non phrasal adjectival compounds and to nominal phrasal compounds. At the same time, they crucially differ from nominal compounds in the prototypical semantic relations between head and non head: adjectival phrasal compounds are mostly similative intensifying as opposed to determinative. We argue that this property is also found in noun adjective compounds and follows naturally from the semantics of the head category in question, viz. adjectives as mostly gradable predicates. In turn, the majority of adjectival phrasal compounds in our data feature a strong expressive component, a characteristic they share with other phrasal compounds.
Age estimation in children using Demirjian's technique: A retrospective study
Year: 2016

Age estimation is a sub discipline of forensic odontology which plays an important part in every identification process, especially when information related to the deceased is unavailable. The aim of this study was to evaluate the accuracy of Demirjian's Dental Age Estimation technique, with the help of Ortho Pantomo Graphs (OPG) in 50 children. 50 OPGs of children in the age group of 6 16 years were randomly selected and a cross sectional retrospective study was conducted. Age estimation was done by the method given by Demirjian and two tailed test of the data was carried out. A significantly high difference was observed in the estimated and chronologic ages in the age group of 13 16 years than in 6 12 years. Demirjian's original method, using seven mandibular teeth is an accurate method of age estimation in children especially of the younger age group (6 12 years of age)
Love and Fear in the Neighbourhood: Emotions and Ontological Security in Foreign Policy Analysis
Year: 2019

The aim of our paper is two fold. First, it wants to contribute to the growing literature on the role of emotions in international relations by exploring how emotions are fundamental to ontological security. We explore the extent to which love and fear are part of the practices and routines that give the EU and Russia ontological security and shape how they relate to each other. Emotions, we will argue, are not just what we feel but also what we do to make sense of the world and to transmit to others how we understand it. Second, we argue that the narratives at the heart of the conceptual and normative maps that guide their actions and behaviour create a sort of (ontological) security dilemma; that is, behaviour aimed primarily at enhancing confidence in the identity and continuity of a political community raises alarms for the ontological security of other actors.
Performance improvement in double ended RDTS by suppressing the local external physics perturbation and intermodal dispersion
Year: 2019

We propose and experimentally demonstrate a novel Raman based distributed fiber optics temperature sensor (RDTS) for improving the temperature measurement accuracy and engineering applicability. The proposed method is based on double ended demodulation with a reference temperature and dynamic dispersion difference compensation method, which can suppress the effect of local external physics perturbation and intermodal dispersion on temperature demodulation results. Moreover, the system can omit the pre calibration process by using the reference temperature before the temperature measurement. The experimental results of dispersion compensation indicate that the temperature accuracy optimizes from 5.6degC to 1.2degC, and the temperature uncertainty decreases from 16.8degC to 2.4degC. Moreover, the double ended configuration can automatically compensate the local external physics perturbation of the sensing fiber, which exhibits a distinctive improvement.
A magnetic field evolution scenario for brown dwarfs and giant planets
Year: 2010

Very little is known about magnetic fields of extrasolar planets and brown dwarfs. We use the energy flux scaling law presented by Christensen et al. to calculate the evolution of average magnetic fields in extrasolar planets and brown dwarfs under the assumption of fast rotation, which is probably the case for most of them. We find that massive brown dwarfs of about 70 MJup can have fields of a few kilo Gauss during the first few hundred Million years. These fields can grow by a factor of two before they weaken after deuterium burning has stopped. Brown dwarfs with weak deuterium burning and extrasolar giant planets start with magnetic fields between ~100 G and ~1 kG at the age of a few Myr, depending on their mass. Their magnetic field weakens steadily until after 10 Gyr it has shrunk by about a factor of 10. We use observed X ray luminosities to estimate the age of the known extrasolar giant planets that are more massive than 0.3 MJup and closer than 20 pc. Taking into account the age estimate, and assuming sun like wind properties and radio emission processes similar to those at Jupiter, we calculate their radio flux and its frequency. The highest radio flux we predict comes out as 700 mJy at a frequency around 150 MHz for t Boo b, but the flux is below 60 mJy for the rest. Most planets are expected to emit radiation between a few Mhz and up to 100 MHz, well above the ionospheric cutoff frequency.

An investigation on the effects of phase change material on material components used for high temperature thermal energy storage system
Year: 2016

The latent heat thermal energy storage (LHTES) systems for concentrated solar power (CSP) plants with advanced power cycle require high temperature phase change materials (PCMs) Graphite foams with high thermal conductivity to enhance the poor thermal conductivity of PCMs. Brazing of the graphite foams to the structural metals of the LHTES system could be a method to assemble the system and a method to protect the structural metals from the molten salts. In the present study, the LHTES prototype capsules using MgCl2 graphite foam composites were assembled by brazing and welding, and tested to investigate the corrosion attack of the PCM salt on the BNi 4 braze. The microstructural analysis showed that the BNi 4 braze alloy can be used not only for the joining of structure alloy to graphite foams but also for the protecting of structure alloy from the corrosion by PCM.
Rates of return to education in Sri Lanka
Year: 2018

This paper explores the rates of return to education in Sri Lanka across the sexes and different types of employment during 2009/10. The endogeneity bias suggests that education may be associated with other characteristics such as ability and family background excluding such attributes could lead to biased estimates of the return to education. To deal with this form of bias, the paper uses an Instrumental Variables (IV) approach to measure education. Our results reveal that the OLS estimates are downward biased, in comparison to the IV estimates. Further, we add to the literature by exploring the return to education across levels of education primary, secondary and tertiary and how it varies across sexes and types of employment. Finally for the self employed, we analyse the association between inputs (land, raw materials, labour and capital) education and output using a household level production function for those in agriculture and non agricultural activities. The results suggest that education at higher levels have a positive association with non agricultural output, but not with agricultural output.
On reduced second Zagreb index
Venue: J. Comb. Optim.
Year: 2020

The reduced second Zagreb index $RM_2$ R M 2 of a graph G is defined as $RM_2(G)\sum _{uv\in E(G)(d_G(u) 1)(d_G(v) 1) R M 2 G u v E G d G u 1 d G v 1 where $d_G(u) d G u is the degree of the vertex u of graph G Furtula et al. ( 2014) studied the difference between the classical Zagreb indices of graphs and showed that it is closely related to $RM_2$ R M 2 In this paper, we obtain an upper bound in terms of order n and size m on $RM_2$ R M 2 of $K_{r+1} K r 1 free graphs. Also we prove that among all graphs of order n with chromatic number \chi kh the Turan graph $T_{n,\chi T n kh is the unique graph having the maximum $RM_2$ R M 2 Furthermore, we completely characterize the extremal graphs with respect to $RM_2$ R M 2 among all unicyclic graphs of order n with girth g
Local Standards for Anonymization Practices in Health, Wellness, Accessibility, and Aging Research at CHI
Venue: CHI
Year: 2019

When studying technologies pertaining to health, wellness, accessibility, and aging, researchers are often required to perform a balancing act between controlling and sharing sensitive data of the people in their studies and protecting the privacy of these participants. If the data can be anonymized and shared, it can boost the impact of the research by facilitating replication and extension. Despite anonymization, data reporting and sharing may lead to re identification of participants, which can be particularly problematic when the research deals with sensitive topics, such as health. We analyzed 509 CHI papers in the domains of health, wellness, accessibility, and aging to examine data reporting and sharing practices. Our analysis revealed notable patterns and trends regarding the reporting of age, gender, participant types, sample sizes, methodology, ethical considerations, anonymization techniques, and data sharing. Based on our findings, we propose several suggestions for community standards and practices that could facilitate data reporting and sharing while limiting the privacy risks for study participants.
The Evolution of Dendritic Cell Immunotherapy against HIV 1 Infection: Improvements and Outlook
Venue: Journal of immunology research
Year: 2020

Dendritic cells (DC) are key phagocytic cells that play crucial roles in both the innate and adaptive immune responses against the human immunodeficiency virus type 1 (HIV 1) By processing and presenting pathogen derived antigens, dendritic cells initiate a directed response against infected cells. They activate the adaptive immune system upon recognition of pathogen associated molecular patterns (PAMPs) on infected cells. During the course of HIV 1 infection, a successful adaptive (cytotoxic CD8+ T cell) response is necessary for preventing the progression and spread of infection in a variety of cells. Dendritic cells have thus been recognized as a valuable tool in the development of immunotherapeutic approaches and vaccines effective against HIV 1. The advancements in dendritic cell vaccines in cancers have paved the way for applications of this form of immunotherapy to HIV 1 infection. Clinical trials with patients infected with HIV 1 who are well suppressed by antiretroviral therapy (ART) were recently performed to assess the efficacy of DC vaccines, with the goal of mounting an HIV 1 antigen specific T cell response, ideally to clear infection and eliminate the need for long term ART. This review summarizes and compares methods and efficacies of a number of DC vaccine trials utilizing autologous dendritic cells loaded with HIV 1 antigens. The potential for advancement and novel strategies of improving efficacy of this type of immunotherapy is also discussed.

PSEUDO RANDOM NUMBER GENERATORS ALGORITHMS AND APPLICATIONS
Year: 2018

Pseudo Random Numbers (PRNs) are a kind of random numbers that are generated using a seed value. PRNs are generated by Pseudo Random Number Generators (PRNGs) which are also known as Deterministic Random Number Generators. There have been various pseudo random number generators proposed from time to time. These PRNGs aim to generate pseudo random numbers that are uniformly distributed, completely random and have a large periodicity. There are many state of the art algorithms that aim to generate such random numbers which further find application in session key generation, simulation and games and other applications requiring long bit sequences. This paper aims to bring together such PRNG algorithms, their statistical results and related applications and also aims to provide a general conclusion as to which of these is the most efficient and best technique.
A Sorted Partitioning Approach to Fast and Scalable Dynamic Packet Classification
Venue: IEEE/ACM Transactions on Networking
Year: 2018

The advent of software defined networking (SDN) leads to two key challenges for packet classification on the dramatically increased dynamism and dimensionality. Although packet classification is a well studied problem, no existing solution satisfies these new requirements without sacrificing classification speed. Decision tree methods, such as HyperCuts, EffiCuts, and SmartSplit can achieve high speed packet classification, but support neither fast updates nor high dimensionality. The tuple space search (TSS) algorithm used in Open vSwitch achieves fast updates and high dimensionality but not high speed packet classification. In this paper, we propose a hybrid approach, PartitionSort, that combines the benefits of both TSS and decision trees achieving high speed packet classification, fast updates, and high dimensionality. A key to PartitionSort is a novel notion of ruleset sortability that provides two key benefits. First, it results in far fewer partitions than the TSS. Second, it allows the use of multi dimensional interval trees to achieve logarithmic classification and update time for each sortable ruleset partition. Our extensive experimental results show that The PartitionSort is an order of magnitude faster than the TSS in classifying packets while achieving comparable update time. The PartitionSort is a few orders of magnitude faster in construction time than SmartSplit, a state of the art decision tree classifier, while achieving a competitive classification time. Finally, the PartitionSort is scalable to an arbitrary number of fields and requires only linear space.
Research on brand Positioning Validity in Xiaomi enterprise Management
Year: 2021

With the development of market economy, fierce competition has penetrated into every aspect of the society. In the past, Chinese companies have gained a large market share by relying on the price advantage of low priced products. However, in recent years, labor costs have been rising, environmental damage has become more serious, and independent innovation is very important in enterprise management. All these mean that what is important now is not to find ways to reduce the cost of products, but to find ways to optimize enterprise management strategy. Therefore, in the process of enterprise management, brand positioning is particularly important. First of all, on the basis of literature research, this paper puts forward two brand positioning measurement indexes, namely consistency and brand positioning performance: consistency is mainly used to test the expectations of the enterprise design image and it fits the customer image, and brand performance is mainly from the customer perspective to examine the effects of brand positioning, or used to measure the consumers' brand loyalty. Secondly, this paper selects Xiaomi as a case for empirical study, and conducts questionnaire distribution and data collection and analysis based on the case of xiaomi's enterprise management. Finally, this paper uses SPSS software to analyze the data collected to verify the consistency of brand positioning and brand positioning performance of Xiaomi in enterprise management, and also to verify the positive correlation between the two. The investigation of this paper finally confirms the validity of brand positioning of Xiaomi's enterprise management process, and also shows that the designed indicators are reasonable.
Trust and Relationship Building: Critical Skills for The Future of Design Education in Online Contexts
Year: 2011

AbstractCould you trust someone you had never physically met to successfully collaborate with you on a design project?As online communication technologies rapidly evolve, the creative industries continue to move towards globally networked and interdisciplinary modalities of practice. These inescapable shifts in the ways designers work have challenged many long held assumptions about the nature of individual design processes.Such revolutionary changes mean that designers must increasingly master new skills to effectively communicate and collaborate in online environments with colleagues from different cultures, disciplines and locations world wide. Since they may never meet face to face, the success of this new working methodology relies on high levels of trust between practitioners, both personally and professionally in order to achieve effective design outcomes.In turn the need for design educators to equip students with skills to thrive in the face of this new industrial paradigm is highlighted.

Updates and perspectives on the utilization of molecular makers of complex traits in rice.
Venue: Genetics and molecular research GMR
Year: 2012

After complete sequencing of its genome and annotation of the majority of its ~32,000 genes, rice genome has become the model genome among the cereal genomes, and the focus has shifted from structural to functional genomics and application of genomic derived information in rice breeding. During the past 2 decades, intensive worldwide efforts have led to significant improvements in rice. An abundance of molecular markers and information related to many genes/quantitative trait loci that control agronomically important traits such as yield, quality, and biotic and abiotic stress tolerance have been identified. Bridging the application gap between quantitative trait locus identification and marker assisted selection breeding is an urgent, arduous, and long term task. Marker development, allele mining, gene discovery, and molecular breeding have progressed to a great extent because of the rapid development of next generation sequencing, large scale high density genotyping, and genome wide selection strategies. The availability of high density markers and the rapidly decreasing cost of genotyping have facilitated marker assisted selection of many traits that were previously not possible.
Compensation as a Police Candidate Attraction Tool: An Organizational Level Analysis
Year: 2017

In 2008, state and local law enforcement agencies hired 61,000 new full time sworn personnel. To develop a sufficient applicant pool, organizations may use a variety of attraction strategies, including financial inducements, especially when broader factors lessen the appeal of a job. Using data from the 2007 and 2013 Law Enforcement Management and Administrative Statistics survey, the present study tests whether unfavorable contingencies (e.g. high cost of living, rigorous application standards) are related to officer compensation pay, supplemental incentives, and reimbursements within a sample of large metropolitan police agencies. Results are generally consistent with contingency theory, at least with respect to salaries. Departments offer higher salaries to offset more rigorous hiring standards, high costs of living, and other unfavorable contingencies. The implications of the findings for police officer recruitment are discussed.
