cup-stacked carbon nanotubes Mechanical and shape recovery properties of shape memory polymer composite embedded with

This study investigated the mechanical and shape recovery properties of a styrene-based shape memory polymer composite reinforced by cup-stacked carbon nanotubes. Due to their unique morphology, cup-stacked carbon nanotubes could be well dispersed in the polymer matrix and offer remarkable benefits in the load transfer between the reinforcement fillers and shape memory polymer. Under the same amount of fillers, shape memory polymer composites embedded with cup-stacked carbon nanotubes exhibit superior mechanical properties in comparison with those embedded with multiwalled carbon nanotubes and carbon nanofibers. The elastic modulus, tensile strength, and flexural strength of the 2 wt% cup-stacked carbon nanotube–reinforced shape memory polymer composite increased by 61%, 66%, and 84%, respectively. It was also found that the glass transition temperature of shape memory polymer composite decreased from 61.9 C to 52.8 C by introducing 2 wt% cup-stacked carbon nanotubes, indicating that the shape recovery process could be triggered more easily by external stimulus due to the role of reinforcement fillers. Finally, under the external resistance load, the developed shape memory polymer composite was successfully driven to recover their shapes under thermal stimulus. The cup-stacked carbon nanotubes were proved to be a promising candidate for the polymer reinforcement.
Long non-coding RNA PANDAR enhances osteosarcoma cell proliferation and invasion through induction of epithelial-to-mesenchymal transition

Objective: Long non-coding RNA (lncRNA) PANDAR has been identified as an oncogenic gene in multiple human malignancies, and dysregulation of PANDAR was tightly linked to carcinogenesis and cancer progression. Herein, we aimed at elucidating the expression profile and biological function of PANDAR in osteosarcoma (OS). Methods: PANDAR expression in OS tissues and cell lines was investigated using qRT-PCR, and the association between PANDAR expression and clinicopathological factors of OS patients was also analyzed. Cell proliferation and transwell assays were conducted by using MG63 and U2OS cells transfected with si-PANDAR. Expression of EMT markers (E-cadherin, N-cadherin and vimentin) was validated using western blot assay. OS xenograft tumor model was set up to investigate the biological functions of PANDAR in vivo. Results: Our findings demonstrated that PANDAR levels were evidently increased in OS tissues and cell lines. Higher expression of PANDAR was associated with aggressive phenotypes of OS, and led to a more unfavorable five-year survival of OS patients. Knock-down of PANDAR impaired the proliferation, migration and invasion of MG63 and U2OS cells in vitro, suppressed in vivo OS xenograft tumor growth, and led to elevated E-cadherin protein expression and reduced N-cadherin and vimentin protein expression. Conclusions: Collectively, the present study provided evidence that overexpression of PANDAR promoted proliferation and EMT-mediated OS migration and invasion. PANDAR may serve as a potential diagnostic indicator and therapeutic target for OS patients.
Morphological characterization of Kielmeyera coriacea Mart. Cork from brazilian Cerrado

Kielmeyera coriacea Mart. , known as "pau-santo", is mentioned in the literature as the main tree species which produces cork of the Brazilian Cerrado. The purpose of this study was to describe the morphological aspect of Kielmeyera coriacea ("pau-santo") cork cells through its microscopic structure and to compare it with the cellular morphology of Quercus suber (cork oak), which is the main cork producing species worldwide. The bark from three trees of the species Kielmeyera coriacea Mart. was collected randomly at points 1.30 m above the ground, with four repetitions per sample. Samples came from native stands situated in the region of Luminarias - MG, Brazil. The study of morphological characteristics was conducted by counting the number of sides of the cells, and measuring the dimensions of the cells from images obtained by scanning electron microscopy (SEM). Images were analyzed using the LEOUIF software. The distribution in faces and edges of cork cells from Kielmeyera coriacea, was observed to have from 4 to 8 sides, with a predominance of hexagonal cells, similar to Quercus suber. The averages of height and thickness of the cell walls were 40 to 70 µm and 1.5 to 2.0 µm respectively, indicating cells from an early growth season. Both height and thickness were observed to be greater than those present in Quercus suber.
The Effects of Body Mass Index (BMI) on Multiple Sclerosis (MS) Progression

Objective: To evaluate the association between Body Mass Index (BMI) and Multiple Sclerosis (MS) Progression as measured by the Expanded Disability Status Scale (EDSS), Magnetic Resonance Imaging (MRI) new lesions, relapse rate, and the Timed 25 Foot Walk (T25FW). Methods: Subjects (n=150) were identified through age, gender, race, and disease duration and followed retrospectively for 5 years based on medical records. Logistic regression analysis was performed to determine the association between BMI and MS progression. Results: The mean age was 45.5 years, 79% were females and the mean BMI was 27. The odds of having increased EDSS by at least 1 point in obese patients with mild disability was 8 times greater than those with normal BMI (p=0.017). The odds of having new brain MRI lesions was 6.2 times greater in overweight subjects (p<0.0001) and 2.6 times greater in obese subjects (p=0.048) than in subjects with normal BMI. The odds of having at least 1 relapse in 5 years was 3.8 times (p=0.040) in obese subjects than non obese. The odds of having 20% change on the T25FW was 1.1 (p=0.047). African Americans had 5 times greater odds to have higher disability (p=0.015) than Caucasians, and current smokers had 5 times greater odds to have increased disability than never Smokers (p=0.03). Conclusions: BMI has an important role in MS outcomes. Assessment and addressing a plan of care with dietary guidelines and weight control programs for patients with MS aid in minimizing the progression of the disease.
Hierarchical segmentation of graphical interfaces for Document Object Model reconstruction

Recently, systems that generate source code from bitmap renderings of graphical user interfaces have started to be developed (Beltramelli, 2017). Here we experiment with a new approach that is able to reconstruct the hierarchical structure of elements displayed in the graphical layout. As a case study, we take bitmap snapshots of HTML pages and infer from those the document object model (DOM), which can be then converted straightforwardly to HTML.
A Word Game : Trends of Associative Processing in Individuals with Schizotypal Characteristics

Individuals with schizotypal personality disorder (SPD), or characteristics thereof, demonstrate elevated creativity, particularly visible in associative processing tasks. It is thought that an abnormal activation of semantic networks underlies the tendency for these individuals to form remote associations through loose and over-inclusive processing. Elevated scores of magical ideation (MI), which surveys beliefs in mysterious causation, have been specifically associated with similar thinking to individuals with SPD. Through a series of three experiments, the current study seeks to examine several associative trends with regards to judgment and response time. In Study 1, low and high MI participants completed an image-word pair association task, judging word pairs produced by other low and high MI participants. Neither convergence nor divergence of associative processes was observed, suggesting an individualized loosening of associative processing. High MI raters, however, did form associations faster and judged words as more likely descriptors of the images than low MI raters. In a follow-up forced-choice judgment task performed by randomly selected participants (Study 2), words that had been given by low MI participants were rated as more likely descriptors of the image than words given by high MI participants. Furthermore, word generation times (Study 3) by low and high MI participants suggest that the creative and loose processing of individuals with high MI scores may translate to verbal fluency tasks as well, as high MI participants generated words slightly faster than low MI participants. Cohesively, the experiments demonstrate the creative and loose associative processing of individuals with SPD by noting their unusual word generation, consistency in judging words as likely descriptors of the image, as well as quick association and word production times.
Understanding the Effectiveness of Video Ads: A Measurement Study

Video streaming nowadays is becoming more and more popular with each passing day. Videos will soon exceed 85% of the global internet traffic in the next few years, and with most traditional TV content moving to the internet, providers have to find new ways how to monetize their content. There are several ways on how to do that, however the main focus of this paper will be to understand how providers can make use of online video ads to monetize their content, and how to make these ads as effective as possible. For this analysis, a data set from 33 video networks including as much as 65 million unique viewers, 362 million watched videos and 257 million ads was collected. Through new techniques such as Quasi Experimental design (QED), it will be shown that an ad is 18.1% more likely to be completed when placed as a mid-roll ad than one that is placed as a pre-roll and it is 14.3% more likely to be completed when placed as a pre-roll than as a post-roll. Additionally, we will see that a 15 second ad is 2.9% more likely to complete than a 20 second one and that in turn is 3.9% more likely to complete than a 30 second ad. Further we will see that ad completion rate is also influenced in the type of video that it is shown on. An ad placed on a long-form video (such as TV Series, Movies) is 4.2% more likely to be completed than an ad placed in a short form video. We will also see some characteristics of viewer behavior and how they behave when abandoning an ad or during different times of the day or week.
Capacity Analysis for Railway Construction using SAT Modulo Discrete Event Simulation

Railway capacity is complex to define and analyze, and existing tools and methods used in practice require comprehensive models of the railway network and its timetables. Design engineers working within the limited scope of construction projects report that only ad-hoc, experience-based methods of capacity analysis are available to them. Designs often have subtle capacity pitfalls which are discovered too late, only when network-wide timetables are made – there is a mismatch between the scope of construction projects and the scope of capacity analysis, as currently practiced. We suggest a language for capacity specifications suited for construction projects, expressing properties such as running time, train frequency, overtaking and crossing. Such specifications can be used as contracts in the interface between construction projects and network-wide capacity analysis. We show how these properties can be verified fully automatically by building a specialpurpose solver which splits the problem into two: an abstracted SAT-based dispatch planning, and a continuous-domain dynamics and timing constraints evaluated using discrete event simulation. The two components communicate in a CEGAR-loop (counterexampleguided abstraction refinement). This architecture is beneficial because it clearly distinguishes the combinatorial choices from continuous calculations, so that the simulation can be extended by relevant details as needed. We describe how loops in the infrastructure can be The first author was partially supported by the project RailCons, — Automated Methods and Tools for Ensuring Consistency of Railway Designs, with number 248714 funded by the Norwegian Research Council.

The Character and Formation of Elongated Depressions 1 on the Upper Bulgarian Slope 2 3

Seafloor elongated depressions are indicators of gas seepage or slope instability. 10 Here we report a sequence of slope-parallel elongated depressions that link to headwalls of 11 sediment slides on upper slope. The depressions of about 250 m in width and several 12 kilometers in length are areas of focused gas discharge indicated by bubble-release into the 13 water column and methane enriched pore waters. Sparker seismic profiles running 14 perpendicular and parallel to the coast, show gas migration pathways and trapped gas 15 underneath these depressions with bright spots and seismic blanking. The data indicate that 16 upward gas migration is the initial reason for fracturing sedimentary layers. In the top 17 sediment where two young stages of landslides can be detected, the slope-parallel sediment 18 weakening lengthens and deepens the surficial fractures, creating the elongated depressions in 19 the seafloor supported by sediment erosion due to slope-parallel water currents. 20 21
Towards for Quantitative Analysis of Official Document Catalog of the Government-General of Formosa

The oficial documents of the government-general of Formosa is the Oficial document colection of Japanese government about Taiwan before the Second World War. The documents are preserved in favorable condition, and were published openly, although the oficial documents of Japanese government in that time have not been published openly. Therefore, those are available for research uses and are very scarce historical documents. Though those documents have been digitized continuously in Chukyo University, the already digitized catalog of those documents in Meiji era was utilized for quantitative analysis of chronological shift in administrative document in that time. As a result, other than human resources and notification and regulations in the government ofice, most frequent category was about hygiene. Especialy cowpox and cholera were mentioned frequently.
Hybrid Generation Systems Planning Expansion Forecast State of the Art Review : Optimal Design vs Technical and Economical Constraints

In recent years the electric power generation has entered into a new development era, which can be described mainly by increasing concerns about climate change, through the energy transition from hydrocarbon to clean energy resources. In order to power system enhance reliability, efficiency and safety, renewable and nonrenewable resources are integrated together to configure so-called hybrid systems. Despite the experience accumulated in the power networks, designing hybrid system is a complex task. It has become more challenging as far as most renewable energy resources are random and weather/climatic conditions-dependent. In this challenging context, this paper proposes a critical state-of-the-art review of hybrid generation systems planning expansion and indexes multi-objective methods as strategies for hybrid energy systems optimal design to satisfy technical and economical constraints.
Vasomotor tone regulation by Rhodiola in rat thoracic aorta

Objective: This study was designed to investigate the effects of Rhodiola and one of its known active components, salidroside, on vasomotor tone regulation in rat isolated thoracic aorta and to explore the possible mechanisms. Materials and methods: Isometric tension was recorded from aortic rings in an organ bath for controlled drug application. To evaluate the influences of Rhodiola and salidroside on endothelial function, aortic rings with intact or denuded endothelium were always tested in parallel. Results: Salidroside (0.1-10.0 g/L) had no influence on the vasomotor tone of aortic rings, while Rhodiola evoked mechanistically distinct all-or-nothing responses at low and high doses. At a relatively low dose (0.1 g/L), Rhodiola induced endothelium-independent contraction of aortic rings at resting tension (P<0.01), a response dependent on extracellular Ca2+ and blocked by an L-type Ca2+ channel antagonist (P<0.01). At a higher dose (0.5 g/L), Rhodiola produced vasoconstriction at resting tension in Ca2+-free medium (P<0.01), a response inhibited by a protein kinase C (PKC) antagonist (P<0.05). Conversely, Rhodiola at the higher dose dilated aortic rings precontracted with phenylephrine (PE) (P<0.01), likely by inhibiting extracellular Ca2+ influx through PE-activated receptor-operated calcium channels (ROCCs) (P<0.01). Rhodiola had no significant influence on K+ channels of vascular smooth muscle cells or on endothelial vascular tension regulation. Conclusions: Rhodiola has mechanistically distinct dose-dependent effects on vascular tension in rat isolated thoracic aorta. However, these responses are produced by active ingredients other than salidroside.
ESTABLISHMENT OF NEAR-REAL TIME MONTHLY GRIDDED DATASET FROM GLOBAL TEMPERATURE AND SALINITY PROFILE PROGRAM ( GTSPP ) USING THE OPTIMAL SPECTRAL DECOMPOSITION ( OSD )

A new data analysis/assimilation scheme, optimal spectral decomposition (OSD), has been developed to analyze fields from noisy and sparse raw data using two scalar representations for a three-dimensional incompressible flow. The analysis procedure is divided into three steps: (a) determining a set of basis functions (i.e., the eigen functions of the Laplacian operator) from the knowledge of boundary geometry and conditions, (b) optimizing the mode truncation, and (c) calculating the spectral coefficients using the observed Global Temperature and Salinity Profile Program (GTSPP) data from solving a large ill-posed algebraic equations with filtration procedure with special regularization. The capability is demonstrated using various examples. Key Words— Optimal spectral decomposition, GTSPP, Argo drifter, Lagrangian data, satellite data, rotation method
CENTERIS-International Conference on ENTERprise Information Systems / ProjMAN-International Conference on Project MANagement / HCist-International Conference on Health and Social Care Information Systems and Technologies , CENTERIS / ProjMAN / HCist 2018 Predictive quality control in BPM : proposing

Business process management (BPM) literature suggests that more than 60% of quality improvement projects fail due to factors associated with the lack of predictive quality control and the search for quality anomalies in quality performance continuously over time. Quality anomalies are indicators of extreme performance deviation from quality expectations and requirements. The findings suggest that quality performance control in BPM is the scientific method for producing quality anomaly knowledge and signalling opportunities for informed, systematic, and continuous quality improvement decisions. A framework based on the findings is proposed, which consists of a structural and procedural component.
Data Binding for Schemata with Integrity Constraints and Atomic Procedures

While XML has become the de facto standard to represent structured data, common XML schema languages are quite restricted in their definition capability. Structural constraints are widely used throughout all schema languages, some languages also support global reference constraints, yet integrity constraints based on local references or values and arithmetic comparisons are uncommon. Data binding techniques, connecting XML with programming languages in a more typesafe way than SAX or DOM, exist for most commonly used schema languages. These techniques are only capable of handling structural constraints. This thesis proposes and implements a binding between schemata supporting more data-centric constraints and class-based object oriented languages. The binding generates class files from a schema file, defines a translation between objects and documents, and checks adherence to integrity constraints of documents and manipulations performed on the objects. The binding puts focus on correctness of constraint checks and usability of the generated library, using several heuristics to assist the user rather than supporting unorthodox schema definitions.
Numerical investigation of optical gain in tensile strained germanium layers for near infra-red lasers

The field of silicon photonics has seen rapid development over the past few years, with high performance siliconcompatible modulators, detectors, filters and (de)multiplexers all demonstrated. The key missing component is a silicon-compatible light source. Whilst silicon is a very poor light emitter (except via the Raman process [1]), germanium holds much more promise, having a direct interband transition only ~140meV above the indirect band gap, and with an energy corresponding to a photon wavelength of 1.55um, an industry standard communications wavelength. The direct optical transition in germanium can be enhanced by a combination of tensile strain (which reduces the  valley energy minimum relative to that of the L valley) and heavy n-type doping (which fills low-lying states in the L valley; hence increasing the probability that injected electrons will populate the  valley and thus contribute towards population inversion at or near the  point) – see fig. 1. Using this approach, both optically pumped and electrically injected laser operation have been reported [2,3]. The optically active Ge layer in the devices had a biaxial tensile strain level of ~0.2%, which results from the differing thermal contraction rates in epitaxial Ge and the underlying Si substrate, upon cooling from the Ge crystal growth temperature. However, other experimental studies have concluded that net gain is not possible in Ge structures with low levels of tensile strain, due to strong optical re-absorption[4].
A Simple Demonstration that the Global Positioning System ( GPS ) is Vulnerable to Spoofing

The Global Positioning System (GPS) is a powerful navigational tool. In our experience, however, security managers using GPS for cargo security and tracking applications often believe that GPS offers high security. This is incorrect: the civilian GPS is not inherently secure. The Department of Transportation (DOT), for example, has raised concerns about GPS vulnerabilities, and about the over reliance on GPS for critical safety and security applications [1]. As a warning, the DOT GPS vulnerability report states that, “As GPS further penetrates into the civil infrastructure it becomes a temping target that could be exploited by individuals, groups or countries hostile to the United States. The potential for jamming exists. The potential for inducing a GPS receiver to produce misleading information exists [1]. ”
