Changes in the structure of various carbon materials generated by thermal treatment were analyzed by Fourier transform infrared (FTIR) spectroscopy. FTIR spectra of different commercially-available carbon materials (activated carbon, carbon black, carbon paper, powdered graphite, expanded graphite, multi-walled carbon nanotubes), as well as carbon film obtained by cellulose foil carbonization, were compared and discussed. The complicated nature of the absorption bands in the 1650–1500 cm–1 region suggests that aromatic ring bands and double bond (C=C) vibrations overlap C=O stretching vibration bands and OH binding vibration bands in different environmental surroundings and represent their mutual interactions. The band in the 1430–1440 cm–1 region observed for some carbon materials ("as received" – graphite, graphitized carbon black, carbon nanotubes), and as result of their thermal treatment (activated carbon) is probably due to antisymmetric stretching vibrations of polynuclear aromatic structures, which seems to be characteristic for more ordered aromatic carbon units (graphene-like) made from well-stacked graphite crystallites. The relative intensity of these bands depends on the degree of carbon material graphitization and can reflect the difference in their chemical reactivity and thermal durability. The changes in the relative intensity of the bands during thermal treatment can be interpreted as the result of the destruction of various surface functionalities, graphitization of the amorphous phase of carbon, and finally, by reactions between the freshly annealed carbon surface with oxygen and water molecules present in air (after contact at ambient temperature). © 2016, Springer Science+Business Media New York.

Formative assessment and summative assessment are two widely accepted approaches of assessment. While summative assessment is a typically formal assessment used at the end of a lesson or course, formative assessment is an ongoing process of monitoring learners' progresses of knowledge construction. Although empirical evidence has acknowledged that formal assessment is indeed superior to summative assessment, current e-learning assessment systems however seldom provide plausible solutions for conducting formative assessment. The major bottleneck of putting formative assessment into practice lies in its labor-intensive and time-consuming nature, which makes it hardly a feasible way of achievement evaluation especially when there are usually a large number of learners in e-learning environment. In this regard, this study developed EduMiner to relieve the burdens imposed on instructors and learners by capitalizing a series of text mining techniques. An empirical study was held to examine effectiveness and to explore outcomes of the features that EduMiner supported. In this study 56 participants enrolling in a "Human Resource Management" course were randomly divided into either experimental groups or control groups. Results of this study indicated that the algorithms introduced in this study serve as a feasible approach for conducting formative assessment in e-learning environment. In addition, learners in experimental groups were highly motivated to phrase the contents with higher-order level of cognition. Therefore a timely feedback of visualized representations is beneficial to facilitate online learners to express more in-depth ideas in discourses. © 2010 Elsevier Ltd. All rights reserved.

VANCOUVER, BRITISH COLUMBIA--(Marketwired - Feb. 27, 2017) - Nevada Copper Corp. (TSX:NCU) ("Nevada Copper" or the "Company") is pleased to announce that its long-term cornerstone shareholder, Pala Investments Limited ("Pala"), has agreed to make a further investment of US$5 million in the Company ("Pala Financing"). Additionally, Nevada Copper has also successfully secured extensions to the loan maturities under its existing senior term loan facility with EXP T1 Ltd, an affiliate of Red Kite Mine Finance ("Red Kite") and its loan facility with Pala. Pala is an experienced investor in the mining sector with a strong track record of successful investments and value creation. Pala's team has extensive experience in project development, financing, construction and expansion projects, and seeks to assist companies in which it has long-term shareholdings by providing strategic support in these areas. With this latest round of investment, Pala's financing support to Nevada Copper since August 2014 is in an aggregate amount of US$30 million. The Pala Financing and the amendments to the Red Kite loan facility will provide greater flexibility to Nevada Copper's balance sheet as the Company progresses its key initiatives and evaluation of various project development options at Pumpkin Hollow in a rising copper price environment. These initiatives include: In connection with these initiatives, Nevada Copper is also pleased to announce that Pala will support Nevada Copper as Technical Adviser to assist its management team in the evaluation and advancements of these projects. "Nevada Copper is pleased to have the continued ongoing support of both Pala and Red Kite. The additional funding from Pala and improved Red Kite loan terms provide Nevada Copper with the opportunity to pursue its key initiatives and evaluation of project development options as copper markets continue to improve. Pumpkin Hollow is a Tier 1 asset which has been significantly de-risked and is fully-permitted/shovel-ready with a 1,900 foot production-sized shaft with lateral development, all of which make it a unique and desirable asset in an improving copper market." Nevada Copper also wishes to announce the streamlining of its board of directors to six members with the retirement of Victor Bradley, Joe Giuffre and Paul Matysek. Nevada Copper wishes to express its gratitude to Messrs. Bradley, Giuffre and Matysek for their invaluable contributions to, and oversight of, the Company over many years. With Mr. Bradley's retirement, the Company is pleased to announce that Evgenij Iorich, a Non-Executive Director, has been appointed Non-Executive Chairman. The Pala Financing is in the form of a convertible loan subordinated to the existing Red Kite loan facility, on terms similar to Pala's existing convertible loans as disclosed in Nevada Copper's announcement dated April 5, 2016 except for certain of the terms described below, and adjusted conversion prices for the new US$5 million loan tranche, as follows: The maturity of Pala's outstanding convertible loans has also been extended to December 31, 2018 such that the maturity is aligned with that of the new loan tranche. In connection with the financing, Pala will be issued 2.5 million warrants with a 3-year term with an exercise price at C$0.97, being a 25% premium to the average 20-day VWAP closing market price of the common shares of the Company on February 24, 2017. The closing of the Pala Financing is subject to customary conditions precedent including receipt of approval of the Toronto Stock Exchange. The receipt of disinterested shareholders' approval is required for the conversion features of the Pala Financing, as detailed above, but this will not delay closing which is expected to occur on or before March 10, 2017. The Pala Financing is a related party transaction of Nevada Copper for purposes of Multilateral Instrument 61-101 Protection of Minority Security Holders in Special Transactions and is subject to the formal valuation and minority approval requirements thereof, unless an exemption is available. The Pala Financing is exempt from such requirements since, at the time the transaction was agreed to, the fair market value of the transaction did not exceed 25 per cent of Nevada Copper's market capitalization. The Pala Financing was reviewed and approved by Nevada Copper's board of directors (with all Pala's nominee directors abstaining from voting). Under the amendments to the Red Kite loan facility, monthly interest payments for March to June 2017, estimated at US$4.8 million, will be prepaid from proceeds of the Pala Financing. Interest payments for the balance of 2017 and 50% of the 2018 monthly interest will be accrued. The milestone deadlines for project construction drawdown conditions to be satisfied and the date for first loan principal repayment have both been extended to December 31, 2018. The Pumpkin Hollow copper development is located entirely on private land close to infrastructure with all required power and water supplies secured. With the project entirely on private land, all required Nevada permits for construction and mine operations are in hand (no federal permits are required). With many analysts forecasting improving copper markets over the next few years, the Company's Pumpkin Hollow Copper Project represents an attractive, "shovel-ready", fully-permitted copper project located in an ideal mine-friendly location.

DNA has vast capacity to carry very important information in the form of character strings, some mathematical methods can be applied to convert these character strings to numerical values. This paper explores various such methods to analyze similarity/dissimilarity between sequences. We consider entropy as a measure of information by modifying the entropy expression including shannon's entropy, relative or information in compressed form. The paper has also explored the application of entropy to analyze the sequence string and propose a Markov model based relative distance to compare DNA strings. The results are in the form of phylogenetic tree and it is validated using maximum agreement subtree score and symmetric distance. © 2016 ACM.

TORONTO, ONTARIO--(Marketwired - Feb. 27, 2017) - Pala Investments Limited ("Pala") is pleased to announce that on February 24, 2017, it reached an agreement with Nevada Copper Corp. ("NCU") regarding the amendment of its existing convertible loan facility to NCU (the "Convertible Loan Facility") and the advance of a further US$5,000,000 (less an arrangement fee and expenses) (the "Advance") under the Convertible Loan Facility. The amendments extended the maturity of the Convertible Loan Facility from January 10, 2018 to December 31, 2018. The Advance, and all interest accrued thereon, is convertible at a conversion price of the lower of C$0.90 and 115% of the lowest subscription price of Common Shares issued by the Borrower in connection with any equity financing completed within six months of February 24, 2017. The existing loans under the Convertible Loan Facility, and all interest accrued thereon, remain convertible at a price of C$0.69. Notwithstanding the foregoing, the Advance and the interest accrued thereon, as well as interest accrued on the existing loans after December 31, 2017 will not be convertible until the receipt of shareholder approval of such conversion by NCU. Upon the closing of the funding of the Advance, Pala will also be issued warrants exercisable for 2,500,000 NCU Shares (the "New Warrants") pursuant to a warrant agreement with a 3-year term, exercisable to acquire NCU Shares at an exercise price of C$0.97 per share. Funding of the Advance is subject to customary conditions precedent including receipt of approval of the Toronto Stock Exchange. After funding of the Advance and assuming an exchange rate of C$1.3104 for each US$1.00 (the noon rate as of February 24, 2017, as published by the Bank of Canada), the Advance would be convertible into a total of 7,280,000 NCU Shares (upon obtaining shareholder approval) and the New Warrants will be exercisable for an additional 2,500,000 NCU Shares, together representing an increase of approximately 2.04% in Pala's securityholding percentage in respect of the NCU Shares (based on 88,168,125 NCU Shares currently outstanding). Pala currently holds 40,289,141 NCU Shares, $29,549,377.38 of existing loans under the Convertible Loan Facility and warrants to purchase an additional 2,500,000 NCU Shares (the "Existing Warrants"). Subject to the assumptions set forth above, following the conversion of all amounts under the Convertible Loan Facility and the exercise in full of the Existing Warrants, Pala would hold a total of 98,907,262 NCU Shares, representing approximately 67.38% of the then issued and outstanding NCU Shares (based on 88,168,125 NCU Shares currently outstanding). After funding of the Advance and subject to the assumptions set forth above, following the conversion of all amounts outstanding under the Convertible Loan Facility and the exercise in full of the Existing Warrants and the New Warrants, Pala would hold a total of 108,687,262 NCU Shares, representing approximately 69.42% of the then issued and outstanding NCU Shares (based on 88,168,125 NCU Shares currently outstanding). Pala has acquired these securities for investment purposes and may increase or decrease the investment in the securities of NCU depending on its evaluation of the business, prospects and financial condition of NCU, the market for NCU's securities, general economic and tax conditions and other factors.

Results obtained by the ATLAS and CMS experiments, using data collected in 2011, on the tt production cross section in channels containing a tau lepton in the final state, are presented. The cross sections in the lepton-plus-tau and in the hadronic tau-plus-jets final states have been measured by both collaborations. The technique for the tau lepton reconstruction as well as for the b-jet identification, used by ATLAS and CMS, are described. The trigger and the offline strategies for these measurements are detailed. The results obtained by ATLAS and CMS are compatible with each other and in agreement with the Standard Model (SM) expectation. No hints of new physics are observed. © 2014 Elsevier B.V.

Toward the next generation network (NGN), various mobile devices provide users with abilities of ubiquitous computing and communications, however, with different quality of service (QoS) requirements at the same time. With limited wireless network resource, efficient data transmission is critical to meet different QoS requirements. Scalable video coding (SVC) is expected as an appropriate technology to achieve diverse QoS requirements of multimedia video services in the NGN network. In this paper, we expose a challenge when transmitting SVC video streams over existing open-system-interconnection-based networks. We propose a solution to the challenge and degrade video quality corruption when network resource is stringent. While transmitting SVC streams over QoS enabled mobile worldwide interoperability for microwave access (WiMAX) networks, our proposed cross-multilayer mechanism enables classification and prioritisation of SVC video data according to the significance for decoding dependency. In addition, by completely compatible with mobile WiMAX, our mechanism is easily deployable. Simulations validate performance improvement of our mechanism.

IP multimedia subsystem (IMS) is the core multimedia network in the next generation all-IP environment. It provides access independence for multimedia applications across fixed and mobile access networks. When a roaming IMS subscriber connects to IMS through mobile access networks, handover becomes a critical issue; this needs to be addressed. Since IMS concerns application layer handover for session mobility, the application layer handover takes a long time for recovering the suspended sessions according to the standard IMS session reestablishment procedure. This introduces noticeable service interruption to end users and cannot be tolerated for real-time applications. In this paper we propose a fast IMS service recovery mechanism to shorten the service recovery latency by combining the IEEE 802.21 Media Independent Handover service and the IRTF Media-Independent Pre-Authentication frameworks. The proposed mechanism performs the necessary IMS registration and QoS re-negotiation procedures in advance of lower-layer handover. Thus it reduces the service recovery latency for suspended services. With parallel design in time, the proposed mechanism is able to shorten overall handover relevant latency as well. Technical examination shows that it is easy to deploy the proposed mechanism in current multimedia service environments. © 2012 Springer Science+Business Media, LLC.
