TopicWave : Interactive Visual Analytics of Spatiotemporal Topics Distribution of People ‟ s Reactions to Events from Geotagged Social Media

People often post messages in social media to express their opinions and ideas concerning various events happening in the world. It is an interesting but challenging task to understand how the opinions vary across people, locations, and times. We propose TopicWave, an approach combining topic modelling with interactive visual techniques, for exploring the spatial-temporal variation of discussion topics derived from people's reactions to significant events expressed in geotagged social media. To create suitable input data for topic modelling, we aggregate social media messages coming from each user and from each location by time intervals. From topic overview to details, we visualize the evolution of discussion topics, which are represented by significant keywords, for groups of users or locations using a river metaphor. Interactive tools allow the analyst to explore how the popularity of each topic and its semantics (i.e., the representative keywords) vary over the sets of people and locations and evolve over time. We demonstrate the use of the proposed approach by example of analysing geotagged Twitter messages related to the Brexit event.
Single-dot spectroscopy of boron and phosphorus codoped silicon quantum dots

Boron (B) and phosphorous (P) codoped silicon quantum dots (Si QDs) are dispersible in polar solvents without organic ligands, and exhibit size controllable photoluminescence (PL) from 0.85 to 1.85 eV due to the electronic transitions between the donor and the acceptor states. We study the PL spectra of the codoped Si QDs at room temperature and at 77 K. We show that the broad PL band of codoped colloidal Si QDs (full width at half maximum is over 400 meV) is composed of narrower PL bands of individual QDs with different PL energies. We also show that the PL linewidth of individual codoped Si QDs is almost twice as large as those of undoped Si QDs. In contrast to the significant narrowing of the PL linewidth of undoped Si QDs at low temperatures, that of codoped Si QDs is almost independent of the temperature except for a few very small QDs. These results suggest that a large number of B and P are doped in a QD and there are a number of non-identical luminescence centers in each QD.
Low-carbon transition under Agenda2030: Climate-development trade-offs and synergies

Agenda 2030 on the Sustainable Development Goals (SDGs) and the United Nations Framework Convention on Climate Change (UNFCCC)’s Paris Agreement on limiting climate change well below 2oC are two important international agreements adopted in 2015. Although independently defined, targets within these two agreements are strongly linked and the achievement of one can affect the feasibility of others. This study identifies impacts (trade-offs and synergies) of climate mitigation measures (SDG13.2) on all relevant SDGs and compiles the findings in a cross-sectoral framework providing valuable insights into climate-development interactions, relevant to low-carbon strategies design. We found that policies targeting energy efficiency, reduction of demand of products and energy services and actions outside of supply and use of energy provide most development cobenefits. In contrast, nuclear and carbon capture and storage were found to be broadly conflicting with SDGs. Although mostly synergistic, renewables have both positive and negative development impacts, with differences across technology types. Applying gained knowledge on climatedevelopment interactions, we assessed policy coherence in G20 countries for energy security, air pollution and food security and productivity. The results of this assessment show that current climate action is in line with energy security, air pollution, and partly food productivity needs, but less with food security. Introduction The United Nations Framework Convention on Climate Change (UNFCCC)’s Paris Agreement on limiting climate change well below 2oC and Agenda 2030 on the Sustainable Development Goals (SDGs) are two major international agreements that were reached in 2015. Although developed independently, the goals of the two agreements are strongly interconnected. Firstly, Agenda 2030’s SDG13 directly addresses climate change action. Secondly, the Paris Agreement emphasizes the need for sustainable development consideration in low-carbon transitions. Finally, global warming and climate mitigation action have numerous direct and indirect impacts on most other development areas represented by the SDGs. Likewise, the means of reaching development goals can affect future GHG emissions levels.
OPTICAL TRAPPING OF CARBON NANOTUBES AND GRAPHENE

We study optical trapping of nanotubes and graphene. We extract the distribution of both centre-of-mass and angular fluctuations from three-dimensional tracking of these optically trapped carbon nanostructures. The optical force and torque constants are measured from auto and cross-correlation of the tracking signals. We demonstrate that nanotubes enable nanometer spatial, and femto-Newton force resolution in photonic force microscopy by accurately measuring the radiation pressure in a double frequency optical tweezers. Finally, we integrate optical trapping with Raman and photoluminescence spectroscopy demonstrating the use of a Raman and photoluminescence tweezers by investigating the spectroscopy of nanotubes and graphene flakes in solution. Experimental results are compared with calculations based on electromagnetic scattering theory.
Cardiovascular Risk Assessment in Developing World

Many international and national authorities recommend that cardiovascular risk assess- ment using multivariate risk scores be used to identify individuals at high risk of cardiovascular disease (CVD). This approach is likely to assure that resources in developing countries are allocated to those who need it most. However, not many developing countries have implemented this approach and different countries have varying progresses in adopting the concept. While many developing countries solely described estimated cardiovascular risk by applying existing CVD risk scores to their population’s cross-sectional data, a number of countries have validated and recalibrated existing risk scores and only a few have developed new risk scores specific to their populations. To enhance the adop - tion of such a policy in developing countries, new CVD risk prediction charts for low- and medium-resource settings were developed and endorsed by the WHO and International Society of Hypertension. However, a number of issues need to be addressed, including development of population-specific risk scores, recalibration of available risk scores and uncertainty over cost-effectiveness of CVD risk assessment in developing countries. Although this high risk approach might represent an effective and practical strategy for developing countries, a complementary population-based approach is also needed to maximize benefits for CVD prevention.
NANOPARTICLE SIZE MEASUREMENT BY NANOPARTICLE TRACKING ANALYSIS ( NTA ) METHOD

Nanoparticle Tracking Analysis (NTA) is a newly developed method, and in the measure process, there are several factors and parameters which have significant effect on the accuracy of final mean particle size result. In this paper, we analysis the effect of sample concentration, camera parameters (shutter, gain and duration) and analysis parameter (threshold) on the obtained NTA results. Based on the work, appropriate methods about sample preparation and parameters settings in video capturing and analysis process are developed by measuring a polystyrene sample with nominal value of 80nm.
Spin-orbit coupling and phase-coherent transport in InN nanowires

The low-temperature quantum transport properties of gated InN nanowires were investigated. Magnetic-field-dependent as well as gate-dependent measurements of universal conductance fluctuations were performed to gain information on the phase coherence in the electron transport. We found a pronounced decrease in the variance of the conductance by about a factor of 2 in gate-dependent fluctuation measurements if a magnetic field is applied. This effect is explained by the suppression of the Cooperon channel of the electron correlation contributing to the conductance fluctuations. Despite the fact that the diameter of the nanowire is less than 100 nm a clear weak antilocalization effect is found in the averaged magnetoconductance being in strong contrast to the suppression of weak antilocalization for narrow quantum wires based on planar two-dimensional electron gases. The unexpected robustness of the weak antilocalization effect observed here is attributed to the tubular topology of the surface electron gas in InN nanowires.
Ultrasonido Cuantitativo de Calcáneo y Composición Corporal en Niños Preescolares: Consideración de Actividad Física

The aim of this research was to determine the difference in Calcaneus quantitative ultrasound (QUS) and body composition according to physical activity in preschool children. We recruited 296 healthy children (112 girls and 184 boys) from different kindergartens in Vojvodina, Serbia. Children were evaluated for body composition. Quantitative ultrasound (QUS) measurements of the heel were performed using the Speed of sound, Broadband Ultrasound Attenuation, Quantitative Ultrasound Index and Estimated bone mineral density for further analysis. Furthermore, children were divided into three groups according to physical activity. Apart from the differences in Body fat % and body mass, there were no significant group differences for BMI, waist circumference and abdominal skinfold (p>0.05). The ANOVA showed significant differences (p<0.05) in all QUS measurements between three different intensities of physical activity. The results show that Body Mass and Body fat % were important predictors that discriminate children according to physical activity. Moreover, the results show that beside BMI and Body fat %, all calcaneus QUS measurements showed differences according to physical activity level.
The distinctive CFD challenges of computational rheology

In this general lecture, we shall first outline the way computational non‐Newtonian fluid mechanics differs from conventional computational fluid dynamics (CFD). We do this by briefly outlining the major historical developments in this relatively new field of science, which is conveniently called Computational Rheology. To illustrate essential features, we limit the discussion to the Oldroyd B, UCM and Phan‐Thien/Tanner constitutive models. In order to provide a serious challenge to existing numerical codes, we describe some recent unpublished experimental results on flow through a contraction of constant viscosity (Boger) and also shear‐thinning elastic liquids. Both planar and axisymmetric contractions are of interest, and pressure drops and observed flow structures provide the relevant points of contact between experiment and numerical prediction. Numerical codes developed at UWS involving a hybrid finite‐element/finite‐volume scheme for Oldroyd B and Phan‐Thien/Tanner constitutive models are applied to the contraction‐flow problems and an encouraging agreement is demonstrated between theory and experiment. Specifically, the dramatic experimental differences between flow in planar and axisymmetric contractions and between constant viscosity and shear‐thinning polymer solutions are mirrored in the numerical predictions, at least in a qualitative sense. Notwithstanding these encouraging developments, the review ends with a realistic assessment of the challenges still awaiting computational rheologists, with particular reference to the choice of constitutive model and the possibility of further refinements to the numerical techniques.

Innovative Elastic Thin-Film Solar Cell Structures

The idea of thin films dates back to the inception of photovoltaics in the early sixties. It is an idea based on achieving truly low-cost photovoltaics appropriate for mass production, where usage of inexpensive active materials is essential. Since the photovoltaic (PV) modules deliver relatively little electric power in comparison with combustion-based energy sources, solar cells must be cheap to produce energy that can be competitive. Thin films are considered to be the answer to that low-cost requirement [1]. Replacement of single crystalline silicon with poly and amorphous films, caused the decline of material requirements, which has led to lower final prices [2]. Furthermore, the thickness of cell layers was reduced several times throughout the usage of materials with higher optical absorption coefficients. Unique, thin film and lightweight, devices of low manufacturing costs and high flexibility, were obtained by applying special materials and production techniques, e.g. CIS, CIGS or CdTe/CdS technologies and organic elements. Taking advantage of those properties, there is a great potential of new, useful applications, such as building integrated photovoltaics (BIPV), portable elastic systems or clothing and smart textiles as well [3]. Low material utilization, mass production and integrated module fabrication are basic advantages of thin film solar cells over their monocrystalline counterparts [4]. Figure 1 (by NREL) shows the development of thin film photovoltaic cells since 1975. The development of cadmium telluride (CdTe) based thin film solar cells started in 1972 with 6% efficient CdS/CdTe [5] to reach the present peak efficiency of 16.5% obtained by NREL researchers in 2002 [6]. Chalcopyrite based laboratory cells (CIS, CIGS) have recently achieved a record efficiency of 20% [7], which is the highest among thin film PV cells (see Table 1). Solar modules based on chalcopyrites, uniquely combines advantages of thin film technology with the efficiency and stability of conventional crystalline silicon cells [4].
Structural damaging in few -layer graphene due to the low energy electron irradiation

Data of Raman spectroscopy from graphene and few-layer graphene (FLG) irradiated by SEM electron beam in the range of energies 0.2 -30 keV are presented. The obvious effect of damaging the nanostructures by all used beam energies for specimens placed on insulator substrates (SiO2) was revealed. At the same time, no signs of structural defects were observed in the cases when FLG have been arranged on metallic substrate. A new physical mechanism of under threshold energy defect production supposing possible formation of intensive electrical charged puddles on insulator substrate surface is suggested.
New road for telecoupling global prosperity and ecological sustainability

Abstract China's ambitious Belt and Road Initiative, which seeks to expand the ancient land routes that connect China to the Mediterranean Sea and corresponding ocean‐based routes, is expanding global cooperation with profound socioeconomic and ecological implications. As China and associated countries are developing specific policies to implement the initiative, it is important to analyze and integrate major relevant issues. In this article, we discuss several major challenges facing the Belt and Road region: complex natural features, mismatched resources, shared ecological issues, and diverse socioeconomic conditions. To meet the challenges, we apply the integrated framework of telecoupling (socioeconomic and environmental interactions over distances) and propose to enhance infrastructure connection, transboundary actions, scientific and cultural exchanges, and institutional innovations within the Belt and Road region; and collaborate with more international organizations and countries beyond the Belt and Road region for a prosperous and sustainable world.

In particular, remedies for diabetes, stoutness, laxatives and antimycobacterials had awfully tall concert with more than 97% of them achieving besides, by corporal checking the predicted 1808 remedy-warning pairs with Idiom Scrutiny Efficient Voyager (ISEV) we found that 90.73% of such pairs could be inveterate by preclinical/clinical cram or precise dedication. Besides, our comportment could be extended to envisage remedies not covered in the network. Remedies with noteworthy likeness to other remedies in the establish of acquaintances.
Finite element analysis of a simplified stochastic Hookean dumbbells model arising from viscoelastic flows

A simplified stochastic Hookean dumbbells model arising from viscoelastic flows is considered, the convective terms being disregarded. A finite element discretization in space is proposed. Existence of the numerical solution is proved for small data, so as a priori error estimates, using an implicit function theorem and regularity results obtained in [Bonito et al., J. Evol. Equ. 6 (2006) 381–398] for the solution of the continuous problem. A posteriori error estimates are also derived. Numerical results with small time steps and a large number of realizations confirm the convergence rate with respect to the mesh size.
Targeted Therapy ’ s Skin Toxicities after Immunotherapy : Skin Toxicity of Tyrosine Kinase Inhibitor Therapy Following Nilovumab Therapy for Metastatic Renal Cell Carcinoma

Anti-programmed cell death antibodies (anti-PD-1) are currently under development for the treatment of metastatic renal cell carcinoma (mRCC) and safety of subsequent treatment by VEGFR tyrosine kinase inhibitors (TKI) is not known. We report two cases of unexpectedly severe skin rashes occurring on initiation of treatment by the tyrosine kinase inhibitor (TKI) sorafenib after prior treatment with the anti-PD-1 nivolumab. Attention is drawn to the potential skin toxicity of TKI treatment after anti-PD-1 administration.
Modelling Attentional Effects with Head-up Displays

Previous research (McCann, Foyle, & Johnston, 1993) has shown that in a simulated approach to a runway, performance of a choice reaction time task is faster when all relevant information is available on the HUD or in the world, compared to when information has to be acquired from both domains. The present experiment tested two attentional models of these results: attention switching and attention sharing. Removing differential motion cues from the display, so that both the HUD and the world were motionless, attenuated the domain effect. The attenuated difference reflected both slower responses on within-domain trials and faster responses on between-domain trials. We conclude that performance with Head-Up Displays is affected by both attention switching and the degree to which attention is shared between domains.
CONTROLLED RELEASE OF FERTILISER USING MESOPOROUS SILICA NANOPARTICLES

Nanostructured delivery systems for fertilizers could minimize leaching and consequently reduce the amountsapplied. In this study, Mesoporous Silica Nanoparticles (MSNs) were explored as controlled release carriers forfertilizers. A series of MSNs with particle sizes, Barrett-Joyner-Halenda (BJH) pore diameters, Brunauer-Emmett-Teller (BET) surface areas and BJH total pore volumes ranging between 50 nm – 900 nm, 2.4 nm - 4.4 nm, 589 m2g-1- 1013 m2g-1 and 0.61 cm3g-1 – 0.81 cm3g-1 respectively were synthesized via Liquid Crystal Templating Mechanism(LCT). Urea was used as a model fertilizer to access the fertilizer loading and controlled release behaviour of MSNs.Loading was achieved by a simple immersion technique using concentrated aqueous urea solution. As much as19.8 % - 78.2 % of the MSNs surface areas and 16.8 % - 99.0 % of the mesopore volumes were loaded with ureamolecules, mainly by physisorption. In vitro release studies of urea-loaded MSNs (UMSNs) in water indicated aburst release (32 % - 91 %) within the 1st day attributed to the urea adsorbed on the external surfaces, followed bya slow and sustained release for up to 6 days when all urea was released (100 %), ascribed to urea moleculesentrapped in the mesopores. The release profiles were found to vary with the physical properties of MSNs. Greatpotential for the development of fertilizer nanocarrier systems based on MSNs was revealed.
The Development of Bioactive Glass‐Ceramic Substrates with Biocide Activity

The biocide efficiency of bioactive 45S5 Bioglass® derived glass‐ceramic substrates against common Gram positive and Gram negative bacteria, and also against yeast, is investigated in this study. The results confirm the high bactericidal capacity of this material. Inorganic coatings containing silver nanoparticles on glass‐ceramic substrates are developed in order to ascertain whether the presence of silver enhances the biocide activity. It is found that a coating made of soda‐glass containing silver nanoparticles does not improve the antifungal properties of the 45S5 Bioglass® derived glass‐ceramic substrates.
The Impact of a Cognitive Flexibility Hypermedia System on Pre-service Teachers' Sense of Self-Efficacy

The field of teacher education, like other professional programs such as library science and business administration, constitutes an ill-structured domain wherein students often struggle to apply basic kinds of knowledge acquired in the classroom to complex and disparate real world cases. Traditional pre-service education programs often fail to prepare students adequately for what they will encounter in their jobs. This study examines the relative benefits of employing a hypermedia system based on the principles of Cognitive Flexibility Theory (CFT) to improve outcomes in pre-service teacher education. The experimental group was exposed to the CFT-based system, while the control group instead participated in a field experience. The study’s findings suggest that inclusion of CFT-based instructional tools, while improving students’ sense of selfefficacy as teachers, does not result in major gains when compared with field experience. While limited in focus the study lends itself well to broader applicability within other professional domains.
QUANTUM-CLASSICAL CORRESPONDENCE IN THE ORACLE MODEL OF COMPUTATION

The oracle model of computation is believed to allow a rigorous proof of quantum over classical computational superiority. Since quantum and classical oracles are essentially different, a correspondence principle is commonly implicitly used as a platform for comparison of oracle complexity. Here, we question the grounds on which this correspondence is based. Obviously, results on quantum speed-up depend on the chosen correspondence. So, we introduce the notion of genuine quantum speed-up which can serve as a tool for reliable comparison of quantum versus classical complexity, independent of the chosen correspondence principle.
