Structure and Microwave Dielectric Properties of Ultralow‐Temperature Cofirable BaV2O6 Ceramics

Abstract: A new ultralow-temperature-sinterable BaV2O6 ceramic was prepared through a conventional solid-state ceramic method. Thermogravimetric and differential-scanning-calorimetry analyses were performed to confirm the phase formation of BaV2O6. Phase purity and crystal structure of the ceramic material were studied by using X-ray diffraction analysis and Raman spectroscopic studies. BaV2O6 crystallizes in an orthorhombic unit cell, and the calculated lattice parameters are a = 8.532 A, b = 12.583 A, and c = 7.554 A. BaV2O6 ceramic was well sintered at 550 °C for 1 h and exhibited a dense microstructure with excellent microwave properties, for example, a dielectric constant of 11.2, a Qxf value of 42790 GHz, and a temperature coefficient of resonant frequency of 28.2 ppm/°C. The BaV2O6 ceramic exhibits a linear coefficient of thermal expansion of 10 ppm/°C in the range 30–350 °C. The BaV2O6 ceramic shows good chemical compatibility with Al electrodes, which makes it as a suitable candidate material for ULTCC technology.

Historical environmental change in Africa drives divergence and admixture of Aedes aegypti mosquitoes: a precursor to successful worldwide colonization?

Abstract: Increasing globalisation has promoted the spread of exotic species, including disease vectors. Understanding the evolutionary processes involved in such colonisations is both of intrinsic biological interest and important to predict and mitigate future disease risks. The Aedes aegypti mosquito is a major vector of dengue, chikungunya and Zika, the worldwide spread of which has been facilitated by Ae. aegypti's adaption to human-modified environments. Understanding the evolutionary processes involved in this invasion requires characterisation of the genetic makeup of the source population(s). The application of approximate Bayesian computation (ABC) to sequence data from four nuclear and one mitochondrial markers, revealed that African populations of Ae. aegypti best fit a demographic model of lineage diversification, historical admixture and recent population structuring. Since ancestral Ae. aegypti were dependent on forests, this population history is consistent with the effects of forest fragmentation and expansion driven by Pleistocene climatic change. Alternatively, or additionally, historical human movement across the continent may have facilitated their recent spread and mixing. ABC analysis and haplotype networks support earlier inferences of a single out of Africa colonisation event, while a cline of decreasing genetic diversity indicates that Ae. aegypti moved first from Africa to the Americas and then to Asia. ABC analysis was unable to verify this colonisation route, possibly because the genetic signal of admixture obscures the true colonisation pathway. By increasing genetic diversity and forming novel allelic combinations, divergence and historical admixture within Africa could have provided the adaptive potential needed for the successful worldwide spread of Ae. aegypti.

Information Security Management (ISM) Practices: Lessons from Select Cases from India and Germany

Abstract: The increasing dependence of businesses over information and the changing ways of information usage with modern IT/ICT tools and mediums, have created an unavoidable need of information security in organizations. Earlier, the technical measures were used to fulfill this need; however, it has been realized that technology alone is unable to address the challenges of information security management (ISM) in organizations. Management and behavioral aspects are pivotal to build an ISM system in organizations. This paper makes an attempt to understand and examine the current ISM practices of two large size, global IT and management services and consulting orga- nizations, one from India and another from Germany. In a case design, the study adopts qualitative research route and semi-structured interviews were conducted across hierarchy in both the organizations. Observations from interviews are portrayed using descriptive analysis meth- odology. Further, to draw learning from the cases, SAP- LAP method of inquiry was used to understand the present status of ISM practices in both the organizations. Finally, the paper discusses the implications of the findings and scope for the future research.

Human Activity Recognition Based on Spatial Distribution of Gradients at Sublevels of Average Energy Silhouette Images

Abstract: The aim of this paper is to present a unified framework for human action and activity recognition by analysing the effect of computation of spatial distribution of gradients (SDGs) on average energy silhouette images (AESIs). Based on the analysis of SDGs computation at various decomposition levels, an effective approach to compute the SDGs is developed. The AESI is constructed for the representation of the shape of action and activity and these are the reflection of 3-D pose into 2-D pose. To describe the AESIs, the SDGs at various sublevels and sum of the directional pixels (SDPs) variations is computed. The temporal content of the activity is computed through R-transform (RT). Finally, the shape computed through SDGs and SDPs, and temporal evidences through RT of the human body is fused together at the recognition stage, which results in a new powerful unified feature map model. The performance of the proposed framework is evaluated on three different publicly available datasets, i.e., Weizmann, KTH, and Ballet and the recognition accuracy is computed using hybrid classifier. The highest recognition accuracy achieved on these datasets is compared with the similar state-of-the-art techniques and demonstrate the superior performance.

Adoption of Electronic Health Records: A Roadmap for India.

Abstract: Objectives The objective of the study was to create a roadmap for the adoption of Electronic Health Record (EHR) in India based an analysis of the strategies of other countries and national scenarios of ICT use in India. Methods The strategies for adoption of EHR in other countries were analyzed to find the crucial steps taken. Apart from reports collected from stakeholders in the country, the study relied on the experience of the author in handling several e-health projects. Results It was found that there are four major areas where the countries considered have made substantial efforts: ICT infrastructure, Policy & regulations, Standards & interoperability, and Research, development & education. A set of crucial activities were identified in each area. Based on the analysis, a roadmap is suggested. It includes the creation of a secure health network; health information exchange; and the use of open-source software, a national health policy, privacy laws, an agency for health IT standards, R&D, human resource development, etc. Conclusions Although some steps have been initiated, several new steps need to be taken up for the successful adoption of EHR. It requires a coordinated effort from all the stakeholders.
