Electrospun Magnetic Ionic Liquid Based Electroactive Materials for Tissue Engineering Applications

Functional electrospun fibers incorporating ionic liquids (ILs) present a novel approach in the development of active microenviroments due to their ability to respond to external magnetic fields without the addition of magnetic particles. In this context, this work reports on the development of magnetically responsive magneto-ionic fibers based on the electroactive polymer poly(vinylidene fluoride) and the magnetic IL (MIL), bis(1-butyl-3-methylimidazolium) tetrathiocyanatocobaltate ([Bmim]2[(SCN)4Co]). The PVDF/MIL electrospun fibers were prepared incorporating 5, 10 and 15 wt. % of the MIL, showing that the inclusion of the MIL increases the polar β-phase content of the polymer from 79% to 94% and decreases the crystallinity of the fibers from 47% to 36%. Furthermore, the thermal stability of the fibers decreases with the incorporation of the MIL. The magnetization of the PVDF/MIL composite fibers is proportional to the MIL content and decreases with temperature. Finally, cytotoxicity assays show a decrease in cell viability with increasing the MIL content.
Collisionally Heated Dust in Large Magellanic Cloud Supernova Remnants

IRAS additional observations show that luminous (10 4 -10 5 L g ) far-IR sources are associated with the Large Magellanic Cloud (LMC) supernova remnants N63A, N49, N49B, and N186D. Com parison of the IRAS and X-ray data shows that a substantial frac tion of the IR emission from three of the SNRs can be accounted for by collisionally heated dust. The ratio of dust-grain cooling to total atomic cooling is ~10 in X-ray emitting gas (T~10 6 K). We show why dust cooling does not dominate, but probably speeds SNR evolution in an inhomogeneous interstellar medium.
Investigations of modular microfluidic geometries for passive manipulations on droplets

Multiple pipetting is a standard laboratory procedure resulting in the compartmentalisation of a liquid sample. Microfluidics offers techniques which can replace this process by the use of tiny droplets. Passive manipulation on droplets is an interesting and promising approach for the design of microfluidic devices which on one hand are easy-to-use and on the other, execute complex laboratory procedures. We present a comprehensive study of the geometry of microfluidic components which encode different operations on droplets into the structure of the device. The understanding of hydrodynamic interactions between the continuous flow and a droplet travelling through confined space of nontrivial microfluidic geometries is crucial for a rational and efficient design of new generation of modular microfluidic processors with embedded instructions.
MLE Evolution Equation for Fractional Diffusions and Berry-Esseen Inequality of Stochastic Gradient Descent Algorithm for American Option

We study recursive parameter estimation in fractional diffusion processes. First, stability and asymptotic properties of the global maximum likelihood estimator (MLE) of the drift parameter are obtained under some regularity conditions. Then we obtain an evolution equation for the MLE of the drift parameter in nonhomogeneous fractional stochastic differential equation (fSDE) driven by fractional Brownian motion. This equation is then modified to yield an algorithm which is consistent, asymptotically efficient and converges to the MLE. The gradient and Newton type algorithm are firstorder approximations. Finally we study the Berry-Esseen inequality for stochastic gradient descent in continuous time (SGDCT) algorithm for American option. We compare it with Longstaff-Schwartz regression based method.
Shear Wave Velocity Estimation Based on Deep-Q Network

Geoacoustic inversion is important for seabed geotechnical applications. It can be formulated as a problem that seeks an optimal solution in a high-dimensional parameter space. The conventional inversion approach exploits optimization methods with a pre-defined search strategy whose hyperparameters need to be fine-tuned for a specific scenario. A framework based on the deep-Q network is proposed in this paper and the environment and agent configurations of the framework are specially defined for geoacoustic inversion. Unlike a conventional optimization method with a pre-defined search strategy, the proposed framework determines a flexible strategy by trial and error. The proposed framework is evaluated by two case studies for estimating the shear wave velocity profile. Its performance is compared with three global optimization methods commonly used in underwater geoacoustic inversion. The results demonstrate that the proposed framework performs the inversion more efficiently and accurately.
PRESUPPOSITIONS IN GREEN CAMPAIGN STICKERS ISSUED BY INTERNATIONAL ASSOCIATION OF STUDENTS IN AGRICULTURE AND RELATED SCIENCES OF UNIVERSITAS BRAWIJAYA

Key words: presupposition, presupposition trigger, pragmatic presupposition. Presupposition is an important element in a communication process. It is defined as the common knowledge belonging to the speaker. Presupposition could be identified by two ways; presupposition trigger referring to the triggered word in a utterance or written expression, and pragmatic presupposition referring to presupposition which is made by considering the speaker as the one producing the utterance or written expression. Presupposition can be found in daily communication such as, in the campaign. In this study, the writer analyzes presupposition within written expression of the green campaign stickers on IAAS Universitas Brawijaya. There are two problems to be solved, namely (1) What are the presupposition triggers of the written expression used in green campaign stickers of International Association of Students in Agriculture and Related Sciences ‘IAAS’ Universitas Brawijaya? and (2) What are the pragmatic presupposition of the written expression used in green campaign stickers of International Association of Students in Agriculture and Related Sciences ‘IAAS’ Universitas Brawijaya? This study used qualitative approach in document analysis since it focused on analyzing the written expression in the campaign. The data were collected from the green campaign stickers in IAAS Universitas Brawijaya when the stickers were distributed in Car Free Day Malang on Sunday, September 23, 2012. Then, data were analyzed by using Levinson’s theory of presupposition trigger (1983) and Karttunen and Stalnaker’s theory of strategy of pragmatic presupposition (1974). Definite description, change of state verb, question, temporal clasuse, iterative, contrast and comparison, and counter factual condition were categories of presupposition trigger found in the written expressions of 7 green campaign stickers. Then, the result of presupposition triggers became a reference to construct pragmatic presupposition in the written expression of green campaign stickers. The writer suggests the sticker makers make effective and good media. This study is also suggested for the students of linguistics to use this study as an example of presupposition used in mass media. It is also suggested for the next researchers that this study can be used as a reference in the same topic.
Integrated Influencing Mechanism of Potential Drivers on Seasonal Variability of LST in Kolkata Municipal Corporation, India

Increasing land surface temperature (LST) is one of the major anthropogenic issues and is significantly threatening the urban areas of the world. Therefore, this study was designed to examine the spatial variations and patterns of LST during the different seasons in relation to influencing factors in Kolkata Municipality Corporation (KMC), a city of India. The spatial distribution of LST was analyzed regarding the different surface types and used 25 influencing factors from 6 categories of variables to explain the variability of LST during the different seasons. All-subset regression and hierarchical partitioning analyses were used to estimate the explanatory potential and independent effects of influencing factors. The results show that high and low LST corresponded to the artificial lands and bodies of water for all seasons. In the individual category regression model, surface properties gave the highest explanatory rate for all seasons. The explanatory rates and the combination of influencing factors with their independent effects on the LST were changed for the different seasons. The explanatory rates of integration of all influencing factors were 89.4%, 81.4%, and 88.7% in the summer, transition, and winter season, respectively. With the decreasing of LST (summer to transition, then to winter) more influencing factors were required to explain the LST. In the integrated regression model, surface properties were the most important factor in summer and winter, and landscape configuration was the most important factor in the transition season. LST is not the result of single categories of influencing factors. Along with the effects of surface properties, socio-economic parameters, landscape compositions and configurations, topographic parameters and pollutant parameters mostly explained the variability of LST in the transition (11.22%) and summer season (15.22%), respectively. These findings can help to take management strategies to reduce urban LST based on local planning.
Written Reflection Influences Science Students’ Perceptions of Their Own and Their Peers’ Teamwork and Related Employability Skills

The impact of written reflection on tertiary students’ self-efficacy, and corresponding evaluation of their peers’ abilities, is often imprecise and lacking in clarity. This study thus sought to assess the effects of a written reflective diary on science undergraduates’ teamwork-related and other employability skills. Employability skills, in particular students’ teamwork-related skills, are crucial to students’ career development and progression. Assessment was carried out using a series of pre- and post-reflection online surveys, the TeamQ assessment rubric, and student focus groups. Participants identified five key teamwork skills, the importance of which remained constant over time. Written reflection had a significant, positive effect on students’ self-efficacy of their oral communication skills. Students’ written reflections were also important in shaping their perceptions about the domain of fostering a team climate, both in terms of their own self-efficacy and perceptions of their peers’ abilities. This study has interesting implications for future research into science students’ teamwork and other employability skills.
Role of defects in resistive switching dynamics of memristors

Resistive-switching memristors are promising device structures for future memory and neuromorphic computing applications. Defects are shown to be critical for the conducting filament formation, and resulting device performance metrics of memristors. In this prospective article, we investigate the role of defects in the resistive-switching dynamics of filamentary-type memristors, and explore defect-engineering as an effective method to rationally design controllable conduction pathways. Specifically, we propose a data-centric approach that combines the defect-knowledge obtained from first-principles calculations with the materials engineering and characterization efforts.

Reconfigurable Rectifier-Based Detuned Series-Series Compensated IPT System for Anti-Misalignment and Efficiency Improvement

For an inductive power transfer (IPT) system, mobility is one of the most attractive features, but coupling variations can dramatically affect the system's output. In this article, a reconfigurable rectifier-based detuned series-series (SS) compensated IPT system is proposed to tolerate an extensive coupling range and improve the system efficiency simultaneously. The reconfigurable rectifier, which can operate in a full-bridge rectifier mode or a half-bridge rectifier mode, is used to alter the equivalent ac load from one value to the other so the expected coupling range of the detuned SS topology can be extended. At the same time, the system efficiency is also partly improved because the ac load is changed to get closer to the optimal load of the IPT system. First, a detuned SS IPT system with the reconfigurable rectifier is presented and followed by the analysis of the working modes. Then, a detailed parameter design process and switching control of the reconfigurable rectifier are introduced. Finally, a 400-W prototype was constructed to verify the validity of the proposed method. The experimental results demonstrate that the output power fluctuation of the proposed IPT system is less than 17.5% and the lowest efficiency can be improved from 68.6% to 87.5% with the coupling coefficient varying from 0.1 to 0.4. The proposed method can implement significant antimisalignment and efficiency improvement simultaneously, and it is regarded as a potential solution for low-power IPT applications with high spatial mobility.
Tephrochronology of a distal tonstein layer within the Maritsa East lignite basin, Bulgaria: Potential sources of the Miocene large explosive eruption

: This contribution presents the age of the detrital zircons from the coal bearing Miocene succession of the Maritsa East lignite basin. We report a new finding of thin kaolinized pyroclastic beds (tonstein) in the coal bearing succession. The analysis of the detrital age component shows sedimentary input from the basement of the proximal area. The most abundant age cluster 290–315 Ma shows that the predominant sources are the Early Permian–Late Carboni­ ferous intrusions in the area. The newly­recognized tonstein beds represent the products of large, distal pyroclastic erup­ tions and are an important element of the sedimentary succession. They are dated at 14.31±0.30 Ma, which corresponds to the absolute age of the organic matter deposition of the productive middle lignite seam. Their source could most likely be related to the Miocene acid paroxysm ignimbrite eruptions in the Pannonian basin.
An investigation of the transonic pressure drag coefficient for axi-symmetric bodies

Abstract : This thesis investigates the pressure drag coefficient in the transonic regime over an axi-symmetric body, with a set of unique contour surfaces developed in a previous thesis. The contour surfaces were obtained by an exact solution of the small perturbation transonic equation, using the guidelines and tools developed at NPS. In this work, Computational Fluid Dynamics (CFD) was not only used to compute the afterbody contour surface, but also to investigate a conical afterbody and complete bodies, which are composed of an arbitrary forebody (ellipsoid) and a variable afterbody (contour and conical). Euler as well as Navier-Stokes flow-solvers were applied to the geometries of interest, giving Mach-number contours for viscous and inviscid flow, pressure drag coefficient magnitude, and depicting shock wave location. On the basis of these results, it can be verified that our contour surface afterbodies will decrease by 15% the peak of the pressure drag coefficient (C sub d) versus Mach number curves in the transonic regime. These results can be used to design low pressure drag surfaces for such as missiles, projectiles and aircraft engine nacelles. Transonic, Pressure, Drag, Coefficient, Axi-symmetric bodies.

Historical transboundary ozone health impact linked to affluence

Ozone pollution is a major transboundary threat to global health. Systematic improvement of mitigation strategy for transboundary ozone requires a socioeconomic understanding of historical lessons in countries at different affluence levels. Here, we explore the changes in transboundary ozone related premature deaths over 1951–2019 driven by anthropogenic emissions of four country groups categorized by income level. By integrating global emission datasets, a chemical transport model (GEOS-Chem), in situ ozone measurements worldwide and an ozone exposure-response model, we find that mortality caused by transboundary anthropogenic ozone increases by 27 times from 1951 to 2019, and on average contributes about 27% of global anthropogenic ozone related deaths. All groups exert and suffer from substantial transboundary ozone related mortality. The high-income and upper middle groups have each experienced an inverted U-shaped relationship between its affluence and per-million-people contribution to mortality caused by transboundary ozone, with the turning point around 23 000 USD and 6300 USD, respectively. The lower middle group has gradually matched the growth pathway of the upper middle group with a turning point less clear. Concerted efforts to ensure early turning points in less affluent countries will have considerable global health benefits.
Additive Manufactured Polymers in Dentistry, Current State-of-the-Art and Future Perspectives-A Review

3D-printing application in dentistry not only enables the manufacture of patient-specific devices and tissue constructs, but also allows mass customization, as well as digital workflow, with predictable lower cost and rapid turnaround times. 4D printing also shows a good impact in dentistry, as it can produce dynamic and adaptable materials, which have proven effective in the oral environment, under its continuously changing thermal and humidity conditions. It is expected to further boost the research into producing a whole tooth, capable to harmoniously integrate with the surrounding periodontium, which represents the ultimate goal of tissue engineering in dentistry. Because of their high versatility associated with the wide variety of available materials, additive manufacturing in dentistry predominantly targets the production of polymeric constructs. The aim of this narrative review is to catch a glimpse of the current state-of-the-art of additive manufacturing in dentistry, and the future perspectives of this modern technology, focusing on the specific polymeric materials.
Numerical and Experimental Mechanical Analysis of Additively Manufactured Ankle–Foot Orthoses

Growing age and different conditions often require the replacement of orthoses, and FDM-based 3D printing can produce them quickly with less investment. In today’s market for orthotics, these characteristics are highly desired. Therefore, this study is fully focused on the optimization and strength analysis of FDM 3D-printed ankle–foot orthoses (AFO) fabricated using PLA and PLA reinforced with carbon fiber (PLA-C). An increase in ankle plantar-flexor force can be achieved by reinforcing thermoplastic AFOs with CFs. Specially designed mechanical strength tests were conducted at the UTM to generate force–displacement curves for stored elastic energy and fracture studies. The mechanical behavior of both AFOs was predicted with the help of an FEA. The model predictions were validated by comparing them with mechanical strength testing conducted under the same loading and boundary conditions as the FEA. In both the prediction and experimental analysis, the PLA-C-based AFOs were stiffer and could withstand greater loads than the PLA-based AFOs. An area of high stress in the simulation and a fracture point in experimentation were both found at the same location. Furthermore, these highly accurate models will allow the fabrication of AFOs to be improved without investing time and resources on trials.
