Using the smart matrix approach to enhance tadf-oled efficiency and lifetime

The European Training Network TADFlife will train a cohort of young PhD scientists within a multidisciplinary research program conceived from a simple industrial need, high performance blue OLEDs which also have long lifetime. This is not an easy problem to solve, as although OLEDs are now ubiquitous in phone and TV displays, the blue pixels still operate far below the performance and efficiency of the red and green to achieve acceptable lifetime. TADFlife will follow a new approach to solve this problem using the latest generation of OLED materials, thermally activated delayed fluorescent (TADF) emitters. Through a device simulation development program, which incorporates a high degree of basic photophysics input, predictive models of TADFOLED performance and lifetime will be built and used to design new TADF emitters and hosts which overcome the degradation pathways identified from the model predictions. These new materials will then be synthesised. By introducing the concept of the smart matrix, the complex guest host interactions of TADF materials will be included and used to optimise emitter orientation to maximise light out-coupling from devices. Quantum chemistry will use the photophysics results to direct new materials design in tandem with the model predictions. Taking this dual approach, we believe will lead to solutions so far unobtainable for OLEDs. This highly interlinked program gives a fantastic opportunity for the brightest young chemists, spectroscopists, theoreticians and device physicists to work together, learn complimentary skills that will be in high demand from European OLED industries.  Leading experts will give courses on core scientific skills along with soft skills and international secondments will be offered, all to properly prepare them for their future careers. They will be part of a network answering a real industrial need and help to secure the future of our European OLED industries in the global OLED materials arena.
Multi-Dimension Analysis of Guangdong Spatial Transport Superiority

Transport is vital to regional development, which has impact not only on economy but also on society and politics. The level of regional transport consists of the interior connection and inter-regional accessibility, so the transport superiority can be quantified by multi-dimension system analysis. The system includes three dimensions: transport network density, influence degree of transport facilities and diffusion effect of the transport hubs. On the basis of mathematical evaluation model,this paper studies the spatial transport superiority in Guangdong Province, and some conclusions have been drawn. First, the transport superiority of the Pearl Delta is much higher than that of other areas in the province, where the three dimensions are all above the provincial average level. The transport superiority is higher on the east of the Pearl River mouth than on the west. Second, the spatial characteristic shows the transport superiority’s layer-loop structure. The superiority decreases gradually from the core (the Pearl River Delta) to the margin (the north mountain area), from the coast areas to the inland. Moreover, the study also reveals that there is a positive relation between transport superiority and economic development level. The transport superiority is proportionate to the economic development level that can be proved by the regression analysis with transport superiority degree and GDP per capita.
METROGOV

In the last decade the importance of cities on the European
agenda has significantly increased and more recently the
issue of city-regions has come to the forefront.
The partners’ initial discussions focused on the way in
which the very concept of a ’city-region’ should be defined,
with regard to the different examples present in their own
territories. This notion of ’city-regions’, which is extremely
widespread in Great Britain, corresponds to an urban area that extends outside the metropolitan area and takes account
of home-workplace journeys that can cross the administrative
boundaries of an urban nucleus and sometimes even
a country’s borders.
The METROGOV working group aimed to contribute to
the debate on sub-national policy and governance by adding
the evidence base and developing detailed case studies
of good practice.
The METROGOV working group set out to achieve the
following general objectives:
1. To understand what metropolitan cooperation and
governance has entailed to date
2. To identify the added value that comes from city-region
working, e.g. the economic benefits that have occurred and
how the greater scale of governance has affected economic
initiatives
3. To consider how city-regions have reduced parochialism,
in particular exploring how these governance structures can
improve social cohesion within the city-region, resulting in
benefits for all inhabitants
4. To explore how a successful city-region partnership can be
formed and understand how the city-region might be most
effectively resourced in terms of staff and finance
5. To identify limitations and barriers to successful city-region
working, as well as ways in which these might be overcome
6. To reflect upon potential further developments and what
new arrangements are needed to maximise the potential
After a series of working group meetings, the partners came
together to present their conclusions at the final conference
in May 2007.
Through-Foliage detection, including in the outermost regions of the eu

In the last years irregular migration has dramatically increased, and is no longer manageable with existing systems. Improved methods for border surveillance are necessary to ensure an effective and efficient EU border management.  
FOLDOUT focus is on through foliage detection in the inner and outermost regions of the EU. Foliage penetration is an unsolved  important part of border surveillance. By solving the problem of unreliable detections in such harsh environments border guards’ workloads are reduced, costs are reduced and, last but not least, lives can be saved.
Detecting people through dense foliage in extreme climates with only a penetration technology is prone to high fault rates. FOLDOUT will build a system that combines various sensors and technologies and intelligently fuses these into an effective and robust intelligent detection platform.
Fusing several sensor signals increases the effectiveness of detection. Further, sensors will be influenced (i.e. detection parameters adapted) by events detected by other sensors in the vicinity. 
By integrating data, such as vehicle traffic, from outside the immediate border area pre-events can be detected and learned. The events will be analysed with machine learning tools to continuously increase the systems detection and tracking capability. 
FOLDOUT will make the tasks of Border Guards simpler and faster by combining events from various sensors to give a complete situation threat assessment combined with suggested reaction scenarios. 
A two year pilot in Bulgaria and demonstrators in Greece, Finland and French Guiana FOLDOUT will provide fundamental enhancements in the domain of border surveillance and improved search & rescue scenarios.
The United Nations mission in disarmament, demobilization and reintegration in Democratic Republic of Timor-Leste

Timor-Leste during and after the process of disarmament, demobilization, and reintegration (DDR) in the years 2000-2004 did not achieve an acceptable level of security. This article, using a DDR maximalist perspective and a liberal perspective in security studies, examines the UN limitations in providing a solid problem-solving process and its implications for DDR. The qualitative data collected from several personal interviews to different stakeholders is analyzed using thematic analysis. Based on these interviews and observations this research finds that the UN had several limitations to carry out DDR in Timor-Leste, being the most salient, the weak legitimacy and the lack of professionalism in human resources.

Mixing effect of biometric flow channel in microbial fuel cells

Abstract Microbial fuel cell (MFC) technology can utilize microbiology to metabolize organic substance and transform the chemical energy into electrical energy, which can be widely applied to purify the environment and develop new energy. Now, a novel method of biometric mixer and biometric flow channel in MFC rarely utilized previously would be applied and investigated. Two parts of experiment related to biometric channel and biometric mixer experiment will be investigated respectively. Compared with common continuous MFC, the maximum power density of MFC with biometric channel can reach 91.81 mW/m 3 , and the stable discharging voltage can retrain at 0.5 mV. Based on experiment (1), the biometric mixer is added and the effect is discussed. It is found that the average mixing efficiency of nutrient source and bacteria liquid reaches 98%, and the maximum power density reaches 118.34 mW/m 3 , 28.9% higher than that of MFC without mixer. These results show that the biometric channel and biometric mixer can be useful to enhance the power performance and could be widely applied to all kinds of MFCs in the future.
Apatite-Mediated electroporation for efficient delivery of sirna in umbilical cord mesenchymal stem cells for safer allogeneic cell therapy

Mesenchymal stem cells (MSC) isolated from the Wharton jelly of the umbilical cord (UC-MSC) show great potential for the use in allogeneic stem cell therapies for various human diseases. However,  the major limitation for the clinical use of allogeneic UC-MSC is their procoagulation activity, which is a consequence of expression of the tissue factor (TF), that can cause thromboembolism after transplantation, thus limiting their clinical usefulness. Preparation of UC-MSC without the TF (UCMSC-TF-) would enable safe clinical use of UC-MSC and bring their full therapeutic potential for treatment of patients. For this reason, preparation of UCMSC-TF- is the central goal of the “APApore4RNA” project. In the project, UCMSC-TF- will be prepared by utilizing the small interfering RNA (siRNA) directed against TF to silence the expression of TF. The project will develop a novel nanotechnology for ex vivo intracellular delivery of siRNA that will combine the use of biodegradable calcium hydroxyapatite (APA) nanoparticles (NPs) (fellow’s experience) and electroporation (EP) (experience of the company EDUCELL) to enable efficient, safe and reproducible transfection of UC-MSC. The use of APA NPs will be based on the fellow’s recent study published in Biomaterials that revealed their unique membrane-disruptive property that enables rapid permeation of payloads across plasma membrane. Moreover, as APA has low dielectric constant, it is expected that APA NPs will strongly improve the EP process by reducing the applied electric field required for reversible membrane permeabilization and consequently improve the safety and efficacy of EP. In addition, important goal of the “APApore4RNA” project is to gain fundamental knowledge about underlying mechanisms of APA-mediated electropermeabilization of plasma membrane and payload permeation across the membrane.
Searching for the Source Crater of Nakhlite Meteorites

We surveyed the Martian surface in order to identify possible source craters of the nakhlite Martian meteorites. We investigated rayed craters that are assumed to be younger than 11 Ma, on lava surfaces with a solidification age around 1.2 Ga. An area of 17.3 million km2 Amazonian lava plains was surveyed and 53 rayed craters were identified. Although most of them are smaller than the threshold limit that is estimated as minimum of launching fragments to possible Earth crossing trajectories, their observed size frequency distribution agrees with the expected areal density from cratering models characteristic for craters that are less than few tens of Ma old. We identified 6 craters larger than 3 km diameter constituting the potentially best source craters for nakhlites. These larger candidates are located mostly on a smooth lava surface, and in some cases, on the earlier fluvial-like channels. In three cases they are associated with fluidized ejecta lobes and rays - although the rays are faint in these craters, thus might be older than the other craters with more obvious rays. More work is therefore required to accurately estimate ages based on ray system for this purpose. A more detailed search should further link remote sensing Martian data with the in-situ laboratory analyses of Martian meteorites, especially in case of high altitude, steep terrains, where the crater rays seems to rarely survive several Ma.
MATERIAL FLOW MODIFIER AND APPARATUS COMPRISING SAME

Material flow modifiers as disclosed herein overcome drawbacks associated with known adverse flow conditions (e.g., surface erosion, head losses, particulate drop-out, and the like) that arise from flow of certain types of materials (e.g., fluids, slurries, particulates, flowable aggregate, and the like) through a material flow conduit. Such material flow modifiers provide for flow of flowable material within a flow passage of a material flow conduit (e.g., a portion of a pipeline, tubing or the like) to have a rotational flow profile. Advantageously, the rotational flow profile centralizes flow toward the central portion of the flow passage, thereby reducing magnitude of laminar flow to overcome the aforementioned adverse flow conditions.
Metal Contamination of Soils and Prospects of Phytoremediation in and Around River Yamuna: A Case Study from North-Central India

The rapid industrialization and intensive agricultural activities over the last few decades have resulted in accumulation of various pollutants in the environment, which are distributed over wide areas by means of air and water. This has caused visible detrimental effects to the ecosystem and consequences to human health. Today, many soils throughout the world have undesirably high concentrations of heavy metals. These include lead (Pb), cadmium (Cd), zinc (Zn), mercury (Hg), arsenic (As), silver (Ag), chromium (Cr), copper (Cu), iron (Fe), and the platinum group elements. At low or background concentrations, heavy metals are not pollutants. They occur naturally in the environment due to their presence in bedrocks. Some heavy metals such as Zn and Cu are also essential micronutrients for living organisms. Therefore, the term heavy metal pollution refers to heavy metal levels that are abnormally high relative to normal background levels. All heavy metals at high concentration have strong toxic effects and are regarded as environmental pollutants.
Predicting customer churn in mobile networks through analysis of social groups

Churn prediction aims to identify subscribers who are about to transfer their business to a competitor. Since the cost associated with customer acquisition is much greater than the cost of customer retention, churn prediction has emerged as a crucial Business Intelligence (BI) application for modern telecommunication operators. The dominant approach to churn prediction is to model individual customers and derive their likelihood of churn using a predictive model. Recent work has shown that analyzing customers' interactions by assessing the social vicinity of recent churners can improve the accuracy of churn prediction. We propose a novel framework, termed Group-First Churn Prediction, which eliminates the a priori requirement of knowing who recently churned. Specifically, our approach exploits the structure of customer interactions to predict which groups of subscribers are most prone to churn, before even a single member in the group has churned. Our method works by identifying closely-knit groups of subscribers using second order social metrics derived from information theoretic principles. The interactions within each group are then analyzed to identify social leaders. Based on Key Performance Indicators that are derived from these groups, a novel statistical model is used to predict the churn of the groups and their members. Our experimental results, which are based on data from a telecommunication operator with approximately 16 million subscribers, demonstrate the unique advantages of the proposed method. We further provide empirical evidence that our method captures social phenomena in a highly significant manner.
Fragilariopsis kerguelensis size variability from the Indian subtropical Southern Ocean over the last 42 000 years

Abstract In the open Southern Ocean (SO), both modern and past size changes of the diatom Fragilariopsis kerguelensis appear to be strongly controlled by iron availability. Conversely, sea surface temperatures (SST) and sea ice seasonal dynamics take over in the seasonal sea-ice zone where iron is not limiting. No information exists on F. kerguelensis biometry from the subtropical SO, on the other extreme of the thermal and nutrient gradients. We present here new data on mean valve area of F. kerguelensis (FkergArea) from a sediment core covering the last ~42 cal kyrs from the southern Subtropical Front (SSTF) of the Indian sector of the SO, where iron and silica stocks are thought to have been consistently low over this period. Our results suggest that larger F. kerguelensis valves occurred during the Last Glacial period, and declined during the Holocene period. These findings indicate that more favourable SST, within the F. kerguelensis ecological range, during the Last Glacial period may have enabled F. kerguelensis to make better use of the low silica stocks prevailing in the subtropical zone leading to larger valves. Conversely, declining FkergArea during the deglacial and the Holocene periods may have been a result of higher SST which hampered the utilization of silica.
EU Regional Cooperation for SMEs access to Public Procurement

EU regions have developed different policies to provide support to SMEs when participating in projects funded by multilateral donors. However, performance of SMEs is different among regions as confirmed by different studies (DG Enterprise, DG Internal Market) on SMEs access to EU public procurement. Actually this field remains slightly spread among EU SMEs. On the other side, mention is to be made to two initiatives to increase the participation of SMEs in EU tenders: the Small Business Act and a directive proposal. Moreover, since January '06 any company from a non - EU member state (based on specific EU bilateral agreements) is allowed to participate in EU public procurement, thus increasing competition. Therefore and due to all the before mentioned circumstantces, there is a need to better prepare EU SMEs. The overall objective is to increase the competitiveness of EU regions - SMEs in the field of participation in EU tendering systems (incl Structural Funds) (innovative field).
To this end, a medium level cooperation through a balanced partnership of 11 gathering regions from NMS (Bulg, Cz R, Hung, Pol, Rom) and EU15 (Dk, Fr, It, Pt, Sp) is proposed. This approach will also help NMS regions to learn about past mistakes by EU15 states in managing EU Structural Funds. Project activities have been jointly designed and set in a plan involving an active cooperation among all partners aimed at improving capacities and knowledge, thus narrowing the existing gap among strategies actually implemented by them. Outlined activities are: Communication plan, interregional benchmarking research, Joint Working Plan, Joint conferences, Joint thematic seminars, Study visits, Site visits, Staff exchanges, Joint interregional training sessions, Joint thematic surveys, Best practices guides and pilot actions. The environment sector will be given a specific focus. Project activities and results will be spread through different means following publicity requirements.
As a result, the project will contribute to increase the competitiveness of EU SMEs and to achieve the EU strategies for growth, jobs and sustainable development. Key results are: regional policies improved based on internationalisation of SMEs, regional mechanisms innovated to promote efficiently and effectively the participation of SMEs in public procurement, regional stakeholders with capacities and know-how improved to support SMEs raising their success in public procurements, networking increased among less experienced and more experienced regions. Finally, the main project outputs are: 3 Joint conferences, 1 Communication Plan, 33 Regional Dissemination events, 1 Website and 1 Intranet, 5 newsletters, 1 joint brochure, 7 Press releases, 1 Working Plan, 1 Interregional Benchmarking Research, 3 guides created, 6 Joint Thematic Seminars, 3 Study Visits, 3 Site Visits, 3 Staff Exchange, 3 Joint region training sessions, 3 Joint thematic surveys, 3 pilot actions.

Background : Poor environmental conditions contribute to the high incidence of diarrhea, most of those caused by unsecure water and poor health knowledge. This study was conducted to evaluate the mother’s knowledge, attitude, and practice toward safe water usage in Baleendah, Bandung. Methods : A cross sectional descriptive study was conducted in Baleendah during September−October 2012, participated by 210 mothers with 12−59 months children, and using rapid survey method. This study used a questionnaire to measure the three domains, which consists of 8 questions of knowledge, 10 questions of attitudes, 16 questions of practice, and 7 questions of diarrhea. The collected data were analyzed and presented in table. Results : As much as 168 (80%) of mothers were in moderate knowledge status, 126 (60%) of mothers were in moderate attitude status. Practically, 127 (54.7%) of mothers used water from borehole/tube well. Most of the mothers (54.6%) use drinking water from refillable water store. Conclusions : Most mothers who participated have varied moderate knowledge and attitude status, and practice toward safe water usage. DOI : 10.15850/amj.v2n3.503
Symmetry breaking vacua in Lovelock gravity

Higher curvature Lovelock gravity theories can have a number of maximally symmetric vacua with different values of the curvature. Critical surfaces in the space of Lovelock couplings separate regions with different numbers of such vacua, and there exist symmetry breaking regions with no maximally symmetric vacua. Especially in such regimes, it is interesting to ask what reduced symmetry vacua may exist. We study this question, focusing on vacua that are products of maximally symmetric spaces. For low order Lovelock theories, we assemble a map of such vacua over the Lovelock coupling space, displaying different possibilities for vacuum symmetry breaking. We see indications of interesting structure, with e.g. product vacua in Gauss-Bonnet gravity covering the entirety of the symmetry breaking regime in $5$-dimensions, but only a limited portion of it in $6$-dimensions.
