Fabrication and characterization of customized tubular scaffolds for tracheal tissue engineering by using solvent based 3D printing on predefined template

Purpose This paper aims to discuss the successful fabrication of customized tubular scaffolds for tracheal tissue engineering with a novel route using solvent-based extrusion 3D printing. Design/methodology/approach The manufacturing approach involved extrusion of polymeric ink over a rotating predefined pattern to construct customized tubular structure of polycaprolactone (PCL) and polyurethane (PU). Dimensional deviation in thickness of scaffolds were calculated for various layer thicknesses of 3D printing. Physical and chemical properties of scaffolds were investigated by scanning electron microscope (SEM), contact angle measurement, Fourier Transform Infrared Spectroscopy (FTIR) and X-ray diffraction (XRD). Mechanical characterizations were performed, and the results were compared to the reported properties of human native trachea from previous reports. Additionally, in vitro cytotoxicity of the fabricated scaffolds was studied in terms of cell proliferation, cell adhesion and hemagglutination assay. Findings The developed fabrication route was flexible and accurate by printing customized tubular scaffolds of various scales. Physiochemical results showed good miscibility of PCL/PU blend, and decrease in crystalline nature of blend with the addition of PU. Preliminary mechanical assessments illustrated comparable mechanical properties with the native human trachea. Longitudinal compression test reported outstanding strength and flexibility to maintain an unobstructed lumen, necessary for the patency. Furthermore, the scaffolds were found to be biocompatible to promote cell adhesion and proliferation from the in vitro cytotoxicity results. Practical implications The attempt can potentially meet the demand for flexible tubular scaffolds that ease the concerns such as availability of suitable organ donors. Originality/value 3D printing over accurate predefined templates to fabricate customized grafts gives novelty to the present method. Various customized scaffolds were compared with conventional cylindrical scaffold in terms of flexibility.
Ten Facts about Inequality in Advanced Economies

This paper presents 10 basic facts regarding inequality in advanced economies. Income and wealth inequality was very high a century ago, dropped in the 20th century, and has been rising at different speeds across countries since the 1980s. The financial crisis of 2008 does not appear to have inverted this trend. At the global level, while between-country inequality mattered more than within-country inequality in the 1980s, it is the opposite today. The rise of inequality has not been counterbalanced by an increase social mobility. The reduction of gender pay gaps has tempered the rise of inequality in recent decades, but gender inequality remains particularly high among top income and wealth groups. Racial inequalities remain large as well. Evidence suggests that trade and technology alone cannot explain large inequality variations across rich countries. Shifts in tax and wage setting policies, as well as differences in educational and health systems matter a lot.
Empowering female pre-service teachers through culturally responsive teaching: shared and divergent views of Arab and expatriate teacher educators in the United Arab Emirates

ABSTRACT UAE’s education reform initiatives focused on K-12, post-secondary education preparation, accountability, higher standards, and professionalism. UAE’s Ministry of Higher Education brought changes in curricula, syllabi, and framework of teacher preparation programmes. Providing teachers with opportunities to contribute to the development of their country as a driving force in teacher education reform. Faculties in colleges of education for culturally grounded instruction, considered social, cultural, and educational backgrounds of Emiratis. A study explored foreign teachers views of Culturally Responsive Teaching when preparing national pre-service teachers in the UAE, Arab vs expatriate teachers study indicated expatriate educators practiced CRT teaching as it helped connect the curriculum to local culture, increase pre-service teachers’ engagement in class, and capitulate discussions regarding social-cultural issues during class.
Face Recognition Based on Haar Like and Euclidean Distance

In order to improve the recognition rate of multi-face image, this paper proposes a face image recognition method based on haar-like and Euclidean distance. First of all, the initial features of Haar are moved in the image and gradually enlarged, the pixel sum of the feature area is obtained quickly by using the integral graph. The Haar feature is obtained by calculating the difference between black and white pixels in the feature region, and the threshold of weak classifier is calculated. Then, the extracted facial feature data is trained and classified to form a cascade classifier for face detection. Finally, the face of the image to be detected is compared with the training samples by using Euclidean distance. The experimental results show that the time of one attendance is 5-10 seconds and the success rate of face recognition is 91.1%, which verifies the advantage of the algorithm in improving the efficiency of attendance.
Chemical comparison of liverworts using NMR spectroscopy

The lipophilic constituents of liverworts have been studied using 1 H NMR spectroscopy by extracting small samples of the liverworts with the NMR solvent CDCl 3 . One application of the technique has been to compare samples of Adelanthus decipiens of different origin, including herbarium specimens: of particular interest is a re-investigation, using a voucher specimen, of material that was the subject of a GC-MS study in 1981. The strength of the technique is demonstrated by the finding that compounds previously thought to be eudesmanolides are actually wettsteins A and B, two of the ten highly oxygenated naphthalenes acetophenones identified in Adelanthus decipiens . The 1 H NMR spectrum of the extract of one sample of Cryptothallus mirabilis showed that one compound was predominant in the extract; this compound is 15-acetoxypinguisone, a simple derivative of the sesquiterpene ketone first isolated from Aneura pinguis , a fellow member of the Aneuraceae.
Anion Selection Criteria for Water‐in‐Salt Electrolytes

Water‐in‐salt electrolytes have enabled the development of novel high‐voltage aqueous lithium‐ion batteries. This study explores the reasons why analogous sodium electrolytes have struggled to reach the same level of electrochemical stability. Solution structure and electrochemical stability are compared for 11 sodium salts, selected among the major classes of salts proposed for highly concentrated electrolytes. The water environment established for each anion is related to its position in the Hofmeister series and a surprisingly strong correlation between the chaotropicity of the anion and the resulting electrochemical stability of the electrolyte is found. The search for suitable sodium salts is complicated by the fact that higher salt concentrations are needed than for their lithium equivalents. Reaching such a high concentration of >25 mol kg−1 with one or a combination of multiple sodium salts that have the desired properties remains a major challenge. Hence, alternative approaches such as multisolvent systems should be explored. The water solubility of NaTFSI can be increased from 8 to 30 mol kg−1 in the presence of ionic liquids. Such a ternary electrolyte enables stable cycling of a 2 V class sodium‐ion battery based on the NaTi2(PO4)3/Na2Mn[Fe(CN)6] electrode couple for 300 cycles at 1C with a Coulombic efficiency of >99.5%.
An Open Source Toolkit to Parse and Analyze Online Crowdsourced Portals

With the success of crowdsourced portals, such as Wikipedia, Stack Overflow, Quora, and GitHub, a class of researchers is driven towards understanding the dynamics of knowledge building on these portals. Even though collaborative knowledge building portals are known to be better than expert-driven knowledge repositories, limited research has been performed to understand the knowledge building dynamics in the former. This is mainly due to two reasons; first, unavailability of the standard data representation format, second, lack of proper tools and libraries to analyze the knowledge building dynamics. We describe Knowledge Data Analysis and Processing Platform (KDAP), a programming toolkit that is easy to use and provides high-level operations for analysis of knowledge data. We propose Knowledge Markup Language (Knol-ML), a generic representation format for the data of collaborative knowledge building portals. KDAP can process the massive data of crowdsourced portals like Wikipedia and Stack Overflow efficiently. As a part of this toolkit, a data-dump of various collaborative knowledge building portals is published in Knol-ML format. The combination of Knol-ML and the proposed open-source library will help the knowledge building community to perform benchmark analysis.
Vortex random fiber laser with controllable orbital angular momentum mode

In this paper, we propose and experimentally demonstrate a vortex random fiber laser (RFL) with a controllable orbital angular momentum (OAM) mode. The topological charge of the vortex RFL can range from −50 to 50 with nearly watt-level output power. A triangular toroidal interferometer is constructed to verify the spiral phase structure of the generated vortex random laser with a special coherence property. Vortex RFLs with fractional topological charge are also performed in this work. As the first demonstration of a vortex RFL with a controllable OAM mode (to the best of our knowledge), this work may not only offer a valuable reference on temporal modulation of a vortex beam and optical field control of an RFL but also provide a potential vortex laser source for applications in imaging, sensing, and communication.
Rare cases of medulloblastoma with hypermutation

Medulloblastoma is the most common malignant brain tumor of childhood and is considered a tumor with low mutational burden (~1 Mut/Mb). Therefore, though the medulloblastoma genomes have been extensively characterized in literature, reports on potential hypermutations and underlying mutagenic processes in medulloblastomas are limited.
Relativistic Landau quantization in the spiral dislocation spacetime

We analyse the interaction of a relativistic electron with a uniform magnetic field in the spiral dislocation spacetime. We show that analytical solutions to the Dirac equation can be obtained, where the spectrum of energy corresponds to the relativistic Landau levels. We also analyse the influence of the spiral dislocation on the relativistic Landau levels by showing that there exists an analogue of the Aharonov–Bohm effect for bound states.
The Association Between Dietary Antioxidants Intakes and The Risk of Cardiovascular Disease: Tehran Lipid and Glucose Study

Background: Cardiovascular disease (CVD), the leading cause of death worldwide, is the collective term/compound name for disorders afflicting the blood vessels and heart that accounts for 17.9 million deaths in 2016 1. Inflammation and enhanced oxidative stress have been shown as fundamental risk factors in the onset and progression of CVD 2. Chronic inflammatory conditions attenuate blood levels of antioxidants because of the continuous generation of elevated levels of reactive oxygen species (ROS). A sufficient intake of antioxidants is also suggested to beneficially interfere with CVD by quenching ROS 3. Antioxidant vitamins and minerals, such as vitamins A, E, and C, and zinc may slow the development and progression of CVD Aim: This study aimed at investigating the association between daily consumption of dietary vitamins A, E, and C, and zinc and the incidence of cardiovascular disease (CVD). Methods: Eligible adults (n=5102) were selected from the participants of the Tehran Lipid and Glucose Study with an average follow-up of 5.3 years. Dietary intakes were assessed using a valid and reliable semi-quantitative food frequency questionnaire. Anthropometrics and biochemical variables were evaluated at baseline and follow-up examinations. Multivariate Cox proportional hazard regression models were used to estimate the development of CVD associated with total intakes of vitamins A, E, and C, and zinc.Results: This study was conducted on 2,253 men and 2,849 women aged 47.0±11.6 and 45.6±10.5 years, respectively. The main sources of dietary vitamins A, E, and C and zinc were fruits, vegetables, and legumes. Risk of CVD decreased from quartile 1 to quartile 4 for vitamin E intake (HR (95% CI): 1.00, 0.91, 0.77, and 0.57; Ptrend=0.03). The association between risk of CVD and the quartiles of vitamins A and C and zinc intake was not significant.Conclusion: Our study suggested an inverse association between vitamin E intake and the risk of CVD. The results emphasized a potential protective role of its dietary sources in the prevention of CVD.
Cenozoic Evolution of the Sulu Sea Arc‐Basin System: An Overview

The Cenozoic Sulu Sea arc‐basin system is situated in the tectonic junction between the South China Sea (SCS), northern Borneo, Palawan Continental Terrane, Philippine Mobile Belt, and Celebes Sea. We compare new/published geochronological and geochemical data from across the circum‐Sulu Sea region, and summarize seven major magmatic phases from the Middle Eocene to Pleistocene. The Middle Eocene (42.65 Ma) Sabah ophiolite and Eocene‐Oligocene (34‐33 Ma) Central Palawan ophiolite have MORB‐IAT‐transitional features, representing an intraoceanic subduction setting in the Paleogene northern Borneo and central‐southern Palawan. After the SCS opening (∼32 Ma) and ridge jump (∼25 Ma), late‐stage Proto‐SCS subduction (24‐21 Ma) may have formed the Panay arc andesite and the BABB magmatism in SW Zamboanga peninsula. Starting of final convergence between the Palawan Continental Terrane and northern Borneo‐SW Philippines (∼21 Ma) likely caused regional uplift/thrusting, forming the Top Crocker Unconformity and triggering the NW‐dipping Celebes Sea subduction. The subduction may have formed arc magmatism (21‐18 Ma) in the Cagayan ridge and its continuation in Panay and NE Sabah, and opened the NW Sulu Sea back‐arc basin through continental crust attenuation. Subduction rollback likely occurred in 17‐14 Ma and 13‐9 Ma, shifting arc magmatism southeast to the Sulu ridge and opening the SE Sulu Sea back‐arc basin. NW‐dipping Celebes Sea subduction largely ceased after ∼9 Ma, followed by extension‐related uplift/exhumation and 4‐0.2 Ma intraplate volcanism in northern Borneo. SE‐dipping Sulu Sea subduction likely occurred along the Negros‐Sulu trenches, and produced arc volcanism from ∼4 Ma.
Implementing reading interventions to support disadvantaged children in England: insights from a process evaluation

ABSTRACT In this paper, we present insights from the qualitative data collected during a process evaluation of a reading intervention project carried out in primary and secondary schools in West Yorkshire, England. Commercially available reading interventions, financed by the Strategic School Improvement Fund, were delivered by school staff to disadvantaged pupils over a period of four half-terms, and a team of university-based researchers carried out qualitative interviews with members of school staff in order to discover factors that affect the sustainability of school-based reading interventions after the initial funding period, and identify good practice in planning for and meeting sustainability objectives. The data from the interviews enabled the researchers to compare and contrast the experiences of the staff following the different interventions. The findings presented in this paper have generated some helpful guidance about the process of implementing reading interventions in schools successfully, and factors such as staff training, fidelity of implementation and organisational context are discussed.
Spatiotemporal Prediction of Theft Risk with Deep Inception-Residual Networks

Spatiotemporal prediction of crime is crucial for public safety and smart cities operation. As crime incidents are distributed sparsely across space and time, existing deep-learning methods constrained by coarse spatial scale offer only limited values in prediction of crime density. This paper proposes the use of deep inception-residual networks (DIRNet) to conduct fine-grained, theft-related crime prediction based on non-emergency service request data (311 events). Specifically, it outlines the employment of inception units comprising asymmetrical convolution layers to draw low-level spatiotemporal dependencies hidden in crime events and complaint records in the 311 dataset. Afterward, this paper details how residual units can be applied to capture high-level spatiotemporal features from low-level spatiotemporal dependencies for the final prediction. The effectiveness of the proposed DIRNet is evaluated based on theft-related crime data and 311 data in New York City from 2010 to 2015. The results confirm that the DIRNet obtains an average F1 of 71%, which is better than other prediction models.
Violation of Bell inequalities by stochastic simulations of Gaussian States based on their positive Wigner representation

At first sight, the use of an everywhere positive Wigner function as a probability density to perform stochastic simulations in quantum optics seems equivalent to the introduction of local hidden variables, thus preventing any violation of Bell inequalities. However, because of the difference between symmetrically and normally ordered operators, some trajectories in stochastic simulations can imply negative intensities, despite a positive mean. Hence, Bell inequalities do not apply. Here, we retrieve for a weakly squeezed Gaussian state the maximum violation on polarization states allowed by quantum mechanics, for the Clauser-Horn-Shimony-Holt (CHSH), as well as for the Clauser-Horn Bell inequalities. For the case of the Clauser-Horn Bell inequality, the influence of the quantum efficiency of the detectors is studied, and for both inequalities, the influence of the degree of squeezing is assessed, as well as the uncertainty range versus the number of trajectories used in the simulations.
Ecology of Anopheles Mosquito Larvae in Different Ecological Zones in Ghana

Background: Understanding the ecology of larval malaria mosquitoes is important in a changing environment is important in developing effective control tools or programmes. This study characterized the breeding habitats of Anopheles mosquitoes in rural communities in different ecological zones in Ghana during the dry and rainy seasons.Methods: The spatio-temporal distribution, species composition, and abundance of larval Anopheles mosquitoes in breeding habitats were studied in 3 ecological zones of Ghana. These were Anyakpor (Coastal Savanna area), Duase (Forest area), Libga, Pagazaa, and Kpalsogu (Sahel Savanna area). Larvae were collected using standard dippers and were raised in the insectary for identification. Results: Out of a total of 7,984 mosquito larvae collected, 2,152 (27.26%) were Anophelines and were more abundant in the rainy season (70.82%) than in the dry season (29.18 %). The Anophelines were made up of 2,128 (98.88%) An. gambiae s.l. , 16 (0.74%) An. rufipees and 8 (0.37%) An. pharoensis. In Anyakpor and Duase, dug-out wells were the most productive habitat in the dry (1.59 larvae/dip and 1.47 larvae/dip) and rainy seasons (11.28 larvae/dip and 2.05 larvae/dip). The most productive habitats in Kpalsogu were natural ponds in the dry season (0.89 larvae/dip) and swamps in the rainy season (2.57 larvae/dip). In Libga, the most productive habitats were drainage ditches in the dry season (0.30 larvae/dip) and furrows in the rainy season (1.83 larvae/dip). The most productive habitats in Pagazaa were puddles (1.44 larvae/dip). Anopheles coluzii was the most abundant sibling species in all the ecological zones except Libga in the sahel savannah area where An. gambiae s.s was the most abundant. Anopheles melas and An. arabiensis were encountered only in the coastal savannah and the sahel savanna areas respectively. Larval habitat types influenced the presence of larvae as well as larval densities (p < 0.001). The land-use type affected the presence of Anopheles larvae (p = 0.001), while vegetation cover influenced larval densities (p < 0.05). Conclusion: The study revealed that the abundance of Anopheles breeding habitats and hence Anopheles larvae are closely associated with anthropogenic activities. Regulating such activities will lead to a significant reduction in Anopheles breeding habitats.
TPACK in mathematics teacher education: Are teachers ready to teach for ICT literacy?

TPACK is an effective combination of technological content knowledge, pedagogical knowledge, and content knowledge to understand the understanding of how the structure, representation, and adaptation of a topic, problem, and content are adapted according to the interests, technology, and abilities of teachers and presented in teaching. Mastery of teachers’ ICT literacy is not possible without the TPACK that underlies the use of ICT. This article employed the relationship between TPACK and ICT literacy among Indonesian Mathematics Teachers in Senior School background. This research used a quantitative approach which focused on the survey as the chosen research design. The research procedures: 1) finding factor analysis of each construct; TPACK and ICT literacy with Exploratory Factor Analysis; 2) constructs the instrument by Confirmatory Factor Analysis to get a fit model; 3) structural Equation Model for the relationship between TPACK and ICT literacy.

The results of the study revealed that the TPACK construct consisted of 7 valid sub-constructs and ICT literacy consisted of 4 valid sub-constructs. Whereas, the analysis of the data shows a significant relationship between TPACK and ICT literacy with a strong contribution significant relationship between TPACK and ICT literacy (β = .566).
Comparison of Success Rate and Radiological Bone Loss in Patients with Mini-Implant versus Conventional-Sized Implant Removable Prostheses: A Meta-Analysis

Background: The objective of this meta-analysis was to assess whether mini-implants have added benefit in terms of implants success rate and average bone loss over conventional-sized implants after one year of follow-up. Methods: An electronic search of randomized clinical trials was conducted in MEDLINE (via PubMed), Cochrane Central Register of Clinical Trials (CENTRAL) and Web of Science for studies including complete or partial edentulous patients requiring two or four mini-implants or conventional/ standard-sized implants in the maxilla or mandible for implant-supported removable prostheses who completed 12 months of follow-up. Results: The search provided 194 unique articles which were screened for title and abstract. Screening generated 12 articles which went through full-text analysis using eligibility criteria, and 4 articles were included for meta-analysis. Meta-analysis of these studies indicated a non-significant difference in the success rate between the two interventions (OR = 1.69 [0.74, 3.85; p = 0.21]). Bone loss estimates resulted in a significant bone reduction (Mean Difference = -0.74 [-0.95, -0.53; p - with two conventional-sized implants, the estimates were non-significant (Mean Difference = -0.24 [-0.69, 0.20; p = 0.29]). Conclusion: The current evidence does not provide solid evidence of the benefits of one intervention over the other. More studies with follow-up times of 10 and more years are needed as current studies have described the short-term outcomes.
