Triple-band rectangular microstrip antennas using combinations of an open-circuit nearly-quarter-wavelength stub, a resonant U-slot, and a pair of rectangular slots are proposed. A new configuration for a tour-band antenna has been realized by cutting two half U-slots inside a stub-loaded rectangular microstrip patch. The multi-port network models for these antennas are also proposed, which help in analyzing the mode distributions at various frequencies. The multi-band response has been experimentally verified, and close agreement was obtained among the simulated, measured, and theoretical results. © 2006 IEEE.

Due to the advancement of Technologies, many companies and organizations today have huge databases, that grow to a limit of millions of records per day. This data generation and storage has become faster than ever. This resulted in databases of unbounded growth. The data even changes over time. As a consequence, if the data cannot fit into memory, it may be necessary to sample a smaller training set. The data streams have recently emerged to address the problems of continuous data. The mining of such data streams is a unique opportunity and even challenging task. Mining with data streams is the process of extracting knowledge structures from continuous, rapid data records. Due to increased streaming information, data stream mining has attracted the research community. Analyzing data streams helps in applications like scientific applications, business and astronomy etc. In this paper, we present the overview of the growing field of Data Streams. We cover the theoretical basis needed for analyzing the streams of data. We discuss the various techniques used for mining data streams. The focus of this paper is to study the problems involved in mining data streams. Finally, we conclude with a brief discussion of the big open problems in the area. © 2010 IEEE.

The IPv4 address space is quickly getting exhausted, putting a tremendous pressure on the adoption of even more NAT levels or IPv6. On the other hand, many authors propose the adoption of new Internet addressing capabilities, namely content-based addressing, to complement the existing IP host-based addressing. In this paper we propose the intro- duction of a location layer, between transport and network layers, to address both problems. We keep the existing IPv4 (or IPv6) host-based core routing functionalities, while we enable hosts to become routers between separate address spaces by exploring the new location header. For a proof of concept, we modified the TCP/IP stack of a Linux host to handle our new protocol layer and we designed and con- ceived a novel NAT box to enable current hosts to interact with the modified stack.

Hexagonal LaF3:Er3+/Yb3+ phosphor material has been synthesized by chemical precipitation method to obtain high near-infrared to green upconversion (UC) efficiency. Its thermal, structural and fluorescence properties have been studied. UC emission bands have been observed up to 315 nm in UV region. The effect of input pump power on the intensities of various emission bands has been studied in detail and photon avalanche UC mechanism has been identified. On increasing the excitation power, some bands have shown saturation in intensity. Also, at higher pump intensities two new UC bands were observed and their origin has been discussed. The phosphor has also been tested for possible UC-based fingerprint detection. © 2011 Springer-Verlag.

Healthcare organizations are very complex, holding numerous stakeholders with various approaches and goals towards the design of health IT-systems. Some of these differences may be approached by applying the concept of boundary objects in a participatory IT-design process. Traditionally clinical simulation provides the opportunity to evaluate the design and the usage of clinical IT-systems without endangering the patients and interrupting clinical work. In this paper we present how clinical simulation additionally holds the potential to function as a boundary object in the design process. The case points out that clinical simulation provides an opportunity for discussions and mutual learning among the various stakeholders involved in design of standardized electronic clinical documentation templates. The paper presents and discusses the use of clinical simulation in the translation, transfer and transformation of knowledge between various stakeholders in a large healthcare organization.

Freshwater fish are a group that is especially susceptible to biodiversity loss as they often exist naturally in small, fragmented populations that are vulnerable to habitat degradation, pollution and introduction of exotic species. Relatively little is known about spatial dynamics of unperturbed populations of small-bodied freshwater fish species. This study examined population genetic structure of the purple spotted gudgeon (Mogurnda adspersa, Eleotridae), a small-bodied freshwater fish that is widely distributed in eastern Australia. The species is threatened in parts of its range but is common in coastal streams of central Queensland where this study took place. Microsatellite (msat) and mitochondrial DNA (mtDNA) variation was assessed for nine sites from four stream sections in two drainage basins. Very high levels of among population structure were observed (msat FST = 0.18; mtDNA ΦST = 0.85) and evidence for contemporary migration among populations was rare and limited to sites within the same section of stream. Hierarchical structuring of variation was best explained by stream section rather than by drainage basin. Estimates of contemporary effective population size for each site was low (range 28 - 63, Sibship method), but compared favorably with similar estimates for other freshwater fish species, and there was no genetic evidence for inbreeding or recent population bottlenecks. In conclusion, within a stable part of its range, M adspersa exists as a series of small, demographically stable populations that are highly isolated from one another. Complimentary patterns in microsatellites and mtDNA indicate this structuring is the result of long-term processes that have developed over a remarkably small spatial scale. High population structure and limited dispersal mean that recolonisation of locally extinct populations is only likely to occur from closely situated populations within stream sections. Limited potential for recolonisation should be considered as an important factor in conservation and management of this species. © 2012 Hughes et al.

2015 is the centennial of Einstein General Relativity. On this occasion, we examine the General Relativity and Quantum Cosmology (GRQC) field of research by analysing 38,291 papers uploaded on the electronic archives arXiv.org from 2000 to 2012. We establish a map of the countries contributing to GRQC in 2012. We determine the main journals publishing GRQC papers and which countries publish in which journals. We find that more and more papers are written by groups (instead of single) of authors with more and more international collaborations. There are huge differences between countries. Hence Russia is the country where most of papers are written by single authors whereas Canada is one of the countries where the most of papers imply international collaborations. We also study authors mobility, determining how some groups of authors spread worldwide with time in different countries. The largest mobilities are between USA–UK and USA–Germany. Countries attracting the most of GRQC authors are Netherlands and Canada whereas those undergoing a brain drain are Italy and India. There are few mobility between Europe and Asia contrarily to mobility between USA and Asia. © 2015, Akadémiai Kiadó, Budapest, Hungary.

The analysts forecast the global IT spending on remote healthcare delivery market to grow at a CAGR of 25.26% over the period 2014-2019. About IT spending in remote healthcare delivery Affordable healthcare is the right of the citizens of a country. However, delivering quality healthcare to all their citizens is one of the challenges faced by all governments. The problem is common to both developing nations as well as developed nations. The only difference is the extent of the problem. In regions such as the Americas, quality healthcare is not affordable for the rural population. Patients need to visit hospitals for face-to-face consultations and for followups. These visits, including followups for prescription refills, lead to increased cost of care, which decreases affordability and also brings down optimum utilization of healthcare resources, such as doctors, nursing staff, and physicians. The healthcare sector is looking for solutions that can transform the healthcare industry by bringing about changes in healthcare delivery. With the advent of technology and increased penetration of the Internet worldwide, telehealth and mhealth have emerged as alternatives, especially for treating people in remote areas. Telehealth provides remote delivery of healthcare related services using telecommunication technologies. For more information or any query mail at email@example.com mHealth is another solution that delivers quality healthcare to remote areas. It leverages mobile devices to address problems of accessibility and affordability. Healthcare providers have realized the potential benefits of these technologies, but their adoption has been slow.

In early 2016, a group of writers turned a story about the ups and downs of relationships into a hilarious and fun series. It's Complicated, which follows a young woman named Skye, is a story about friendship, acceptance, and self-discovery. In the first season, Skye finds herself stuck in a lease with her ex-boyfriend/now-platonic-friend Lance. Skye has always considered herself straight - until hooking up with a female coworker, Alex, and finding that things are a little more complicated. The second season of the series is about to start filming. It will focus more on Alex, but viewers will have to wait until the new season airs to find out more. Written and directed by Bacaltos, the script was inspired by a friend facing the same questions as Skye. The exuberant cast makes this cathartic and fast-paced series a pleasure to watch. And season two is sure to bring back the fun and even turn it up a few notches. "In August 2015, we wrote a short script about a friend who fell in love with a girl. We shot it a few months later - just for fun," explains Bacaltos. "Little did we know that within months, we would get more than 2,000 subscribers, more than 200,000 total views and be nominated at a web festival. But if we make season two, we need to up our game. This season definitely will be crazier, funnier and more complicated." The team behind It's Complicated is currently crowdfunding on Indiegogo to gather funds for increasing production value. By raising $5,200, they hope to make season two even better than the first. It's Complicated Web Series Season 2 is the second season of a coming-of-age series that focuses on the ins and outs of real life and navigating the rocky waters of relationships. It's a heartfelt story about friendship, acceptance, and self-discovery. To learn more about It's Complicated Web Series Season 2, please visit: https://goo.gl/6pluoO.
