Authors: Ji Yu , Xing Yufeng , Li Xuequan , Shao Li-Hua
Published: November 2019

A dual-stimuli responsive soft actuator based on the three-dimensional (3D) porous carbon nanotube (CNT) sponge and its composite with polydimethylsiloxane (PDMS) was developed, which can realize both electrothermal and electrochemical actuation. The bimorph actuator exhibited a bending curvature of 0.32 cm−1·W−1 under electrothermal stimulation on land. The displacement of the electrochemical actuator could reach 4 mm under a 5 V applied voltage in liquid. The dual-responsive actuator has demonstrated the applications on multi-functional amphibious soft robots as a crawling robot like an inchworm, a gripper to grasp and transport the cargo and an underwater robot kicking a ball. Our study presents the versatility of the CNT sponge-based actuator, which can be used both on land and in water.

The dermatophyte Trichophyton rubrum is the main causative agent of dermatophytoses worldwide. Although a superficial mycosis, its incidence has been increasing especially among diabetic and immunocompromised patients. Terbinafine is commonly used for the treatment of infections caused by dermatophytes. However, cases of resistance of T. rubrum to this allylamine were reported even with the efficacy of this drug. The present study is the first to evaluate the effect of terbinafine using a co-culture model of T. rubrum and human keratinocytes, mimicking a fungus-host interaction, in conjunction with RNA-seq technique. Our data showed the repression of several genes involved in the ergosterol biosynthesis cascade and the induction of genes encoding major facilitator superfamily (MFS)- and ATP-binding cassette superfamily (ABC)-type membrane transporter which may be involved in T. rubrum mechanisms of resistance to this drug. We observed that some genes reported in the scientific literature as candidates of new antifungal targets were also modulated. In addition, we found the modulation of several genes that are hypothetical in T. rubrum but that possess known orthologs in other dermatophytes. Taken together, the results indicate that terbinafine can act on various targets related to the physiology of T. rubrum other than its main target of ergosterol biosynthetic pathway.

Cornea is the transparent layer in front of the eye that does not contain blood vessels. Among eye diseases, corneal neovascularization (NV) is one of the major causes of vision loss, since it can also lead to blindness. An herbal extraction containing flavonoid, kaempferol (KA), with antiangiogenic effect was chosen as a candidate drug for inhibited vessel formation. The use of nanomedicine has led to higher drug bioavailability and slow release of the drug as an effective therapeutic formulation in ocular drug delivery. In this study, we prepared gelatin nanoparticles (GNP) with kaempferol encapsulation (GNP-KA) for corneal NV treatment by topical delivery, i.e., eye drops. We found that GNP with/without KA loading was in the size of 85−150 nm, and its zeta potential was around 22−26 mV. The KA entrapment rate of GNP-KA was around 90−98%, and the loading rate was about 4.6%. The TEM results clearly indicated the GNP-KA NPs to be round spheres. The in vitro test involved the adoption of human umbilical vein endothelial cells (HUVECs) for coculture with these nanoparticles. From WST-8 assay, and cell migration examinations, it was evident that GNP-KA had the capacity to inhibit the cell viability and function of HUVECs. The results from in vivo tests such as ocular vessels observation, hematoxylin & eosin (H&E) stain, and metalloproteinases (MMP)/vascular endothelial growth factor (VEGF) quantification revealed the mice’s eyes with corneal NV treated by eye drops containing GNP-KA once daily for 7 days had better therapeutic effects with less vessels in-growths in the cornea, compared to the KA solution group by reducing the production of MMP and VEGF in the cornea. Therefore, we expected to achieve a comfortable treatment with a simple method using nanomedicine (GNP-KA) as ophthalmological agent delivered as eye drops.
Alternative Pathway is Involved in Nitric Oxide-Enhanced Tolerance to Cadmium Stress in Barley Roots

Published: November 2019

Alternative pathway (AP) has been widely accepted to be involved in enhancing tolerance to various environmental stresses. In this study, the role of AP in response to cadmium (Cd) stress in two barley varieties, highland barley (Kunlun14) and barley (Ganpi6), was investigated. Results showed that the malondialdehyde (MDA) content and electrolyte leakage (EL) level under Cd stress increased in two barley varieties. The expressions of alternative oxidase (AOX) genes (mainly AOX1a), AP capacity (Valt), and AOX protein amount were clearly induced more in Kunlun14 under Cd stress, and these parameters were further enhanced by applying sodium nitroprussid (SNP, a NO donor). Moreover, H2O2 and O2− contents were raised in the Cd-treated roots of two barley varieties, but they were markedly relieved by exogenous SNP. However, this mitigating effect was aggravated by salicylhydroxamic acid (SHAM, an AOX inhibitor), suggesting that AP contributes to NO-enhanced Cd stress tolerance. Further study demonstrated that the effect of SHAM application on reactive oxygen species (ROS)-related scavenging enzymes and antioxidants was minimal. These observations showed that AP exerts an indispensable function in NO-enhanced Cd stress tolerance in two barley varieties. AP was mainly responsible for regulating the ROS accumulation to maintain the homeostasis of redox state.
On Using Inertial Measurement Units for Solving the Direct Kinematics Problem of Parallel Mechanisms
Authors: Schulz Stefan
Published: November 2019

In this paper, we investigate the accuracy and the computational efficiency of an IMU-based approach for solving the direct kinematics problem of parallel mechanisms with length-variable linear actuators under dynamic conditions. By avoiding to measure the linear actuators’ lengths and by using orientations instead, a comprehensive, low-cost sensor structure can be obtained that provides a unique solution for the direct kinematics problem. As a representative example, we apply our approach to the planar 3-RPR parallel mechanism, where P denotes active prismatic joints and R denotes passive revolute joints, and investigate the achievable accuracy and robustness on a specially designed experimental device. In this context, we also investigate the effect of sensor fusion on the achievable accuracy and compare our results with those obtained from linear actuators’ lengths when the Newton-Raphson algorithm is used to compute the manipulator platform’s pose iteratively. Finally, we discuss the applicability of inertial measurement units (IMUs) for solving the direct kinematics problem of parallel mechanisms.
On the Adequacy of Representing Water Reflectance by Semi-Analytical Models in Ocean Color Remote Sensing
Authors: Tan Jing , Frouin Robert , Ramon Didier , Steinmetz François
Published: November 2019

Deterministic or statistical inversion schemes to retrieve ocean color from space often use a simplified water reflectance model that may introduce unrealistic constraints on the solution, a disadvantage compared with standard, two-step algorithms that make minimal assumptions about the water signal. In view of this, the semi-analytical models of Morel and Maritorena (2001), MM01, and Park and Ruddick (2005), PR05, used in the spectral matching POLYMER algorithm (Steinmetz et al., 2011), are examined in terms of their ability to restitute properly, i.e., with sufficient accuracy, water reflectance. The approach is to infer water reflectance at MODIS wavelengths, as in POLYMER, from theoretical simulations (using Hydrolight with fluorescence and Raman scattering) and, separately, from measurements (AERONET-OC network). A wide range of Case 1 and Case 2 waters, except extremely turbid waters, are included in the simulations and sampled in the measurements. The reflectance model parameters that give the best fit with the simulated data or the measurements are determined. The accuracy of the reconstructed water reflectance and its effect on the retrieval of inherent optical properties (IOPs) is quantified. The impact of cloud and aerosol transmittance, fixed to unity in the POLYMER scheme, on model performance is also evaluated. Agreement is generally good between model results and Hydrolight simulations or AERONET-OC values, even in optically complex waters, with discrepancies much smaller than typical atmospheric correction errors. Significant differences exist in some cases, but having a more intricate model (i.e., using more parameters) makes convergence more difficult. The trade-off is between efficiency/robustness and accuracy. Notable errors are obtained when using the model estimates to retrieve IOPs. Importantly, the model parameters that best fit the input data, in particular chlorophyll-a concentration, do not represent adequately actual values. The reconstructed water reflectance should be used in bio-optical algorithms. While neglecting cloud and aerosol transmittances degrades the accuracy of the reconstructed water reflectance and the retrieved IOPs, it negligibly affects water reflectance ratios and, therefore, any variable derived from such ratios.
Kernel Entropy Component Analysis-Based Robust Hyperspectral Image Supervised Classification
Authors: Tu Bing , Zhou Chengle , Peng Jin , He Wei , Ou Xianfeng , Xu Zhi
Published: November 2019

Recently, the “noisy label" problem has become a hot topic in supervised classification of hyperspectral images (HSI). Nonetheless, how to effectively remove noisy labels from a training set with mislabeled samples is a nontrivial task for a multitude of supervised classification methods in HSI processing. This paper is the first to propose a kernel entropy component analysis (KECA)-based method for noisy label detection that can remove noisy labels of a training set with mislabeled samples and improve performance of supervised classification in HSI, which consists of the following steps. First, the kernel matrix of training samples with noisy labels for each class can be achieved by exploiting a nonlinear mapping function to enlarge the sample separability. Then, the eigenvectors and eigenvalues of the kernel matrix can be obtained by employing symmetric matrix decomposition. Next, the entropy corresponding to each training sample in each class is calculated based on entropy component analysis using the eigenvalues arranged in descending order and the corresponding eigenvectors. Finally, the sigmoid function is applied to the entropy of each sample to obtain the probability distribution. Meanwhile, a decision probability threshold is introduced into the above probability distribution to cleanse the noisy labels of training samples with mislabeled samples for each class. The effectiveness of the proposed method is evaluated by support vector machines on several real hyperspectral data sets. The experimental results show that the proposed KECA method is more efficient than other noisy label detection methods in terms of improving performance of the supervised classification of HSI.
Comparison of Hyperspectral Versus Traditional Field Measurements of Fractional Ground Cover in the Australian Arid Zone
Authors: Fisk Claire , Clarke Kenneth , Lewis Megan
Published: November 2019

The collection of high-quality field measurements of ground cover is critical for calibration and validation of fractional ground cover maps derived from satellite imagery. Field-based hyperspectral ground cover sampling is a potential alternative to traditional in situ techniques. This study aimed to develop an effective sampling design for spectral ground cover surveys in order to estimate fractional ground cover in the Australian arid zone. To meet this aim, we addressed two key objectives: (1) Determining how spectral surveys and traditional step-point sampling compare when conducted at the same spatial scale and (2) comparing these two methods to current Australian satellite-derived fractional cover products. Across seven arid, sparsely vegetated survey sites, six 500-m transects were established. Ground cover reflectance was recorded taking continuous hyperspectral readings along each transect while step-point surveys were conducted along the same transects. Both measures of ground cover were converted into proportions of photosynthetic vegetation, non-photosynthetic vegetation, and bare soil for each site. Comparisons were made of the proportions of photosynthetic vegetation, non-photosynthetic vegetation, and bare soil derived from both in situ methods as well as MODIS and Landsat fractional cover products. We found strong correlations between fractional cover derived from hyperspectral and step-point sampling conducted at the same spatial scale at our survey sites. Comparison of the in situ measurements and image-derived fractional cover products showed that overall, the Landsat product was strongly related to both in situ methods for non-photosynthetic vegetation and bare soil whereas the MODIS product was strongly correlated with both in situ methods for photosynthetic vegetation. This study demonstrates the potential of the spectral transect method, both in its ability to produce results comparable to the traditional transect measures, but also in its improved objectivity and relative logistic ease. Future efforts should be made to include spectral ground cover sampling as part of Australia’s plan to produce calibration and validation datasets for remotely sensed products.
Infrared Small-Faint Target Detection Using Non-i.i.d. Mixture of Gaussians and Flux Density
Authors: Sun Yang , Yang Jungang , Li Miao , An Wei
Published: November 2019

The robustness of infrared small-faint target detection methods to noisy situations has been a challenging and meaningful research spot. The targets are usually spatially small due to the far observation distance. Considering the underlying assumption of noise distribution in the existing methods is impractical; a state-of-the-art method has been developed to dig out valuable information in the temporal domain and separate small-faint targets from background noise. However, there are still two drawbacks: (1) The mixture of Gaussians (MoG) model assumes that noise of different frames satisfies independent and identical distribution (i.i.d.); (2) the assumption of Markov random field (MRF) would fail in more complex noise scenarios. In real scenarios, the noise is actually more complicated than the MoG model. To address this problem, a method using the non-i.i.d. mixture of Gaussians (NMoG) with modified flux density (MFD) is proposed in this paper. We firstly construct a novel data structure containing spatial and temporal information with an infrared image sequence. Then, we use an NMoG model to describe the noise, which can be separated with the background via the variational Bayes algorithm. Finally, we can select the component containing true targets through the obvious difference of target and noise in an MFD maple. Extensive experiments demonstrate that the proposed method performs better in complicated noisy scenarios than the competitive approaches.
Perceptions vs. Practice: A Longitudinal Analysis of Energy-Efficient and Energy Conservation Practices in Minnesota’s Tourism Industry
Authors: Orr Madeleine , Qian Xinyi , Schneider Ingrid , Heyn Michelle , Simmons Patrick
Published: November 2019

The importance of adopting sustainable practices in the tourism industry is well established. This project assessed tourism professionals’ perceptions of constraints and benefits to sustainable practices as well as actual implementation of energy practices across time. Adopting a longitudinal approach, perceptions and practices were tracked through an Internet-based questionnaire administered among tourism professionals in 2007, 2010, and 2013 in a Midwestern U.S. state. Professionals consistently agreed that attracting new clientele, improving consumer perceptions, and organizational image were benefits of sustainable practices, while initial financial costs constrained implementation. The most frequently implemented energy practices were using daylight and compact fluorescent light bulbs (CFLs). Only the use of two energy practices increased across time: using CFLs and Energy Star equipment. Overall, the adoption of sustainable practices was varied, and implementation rates remained minimally changed between 2007 and 2013. Reasons for the varied adoption and lack of changes in practice implementation may be explained by perceived barriers to implementation, lack of perceived benefits, and socio-economic contextual factors. With consideration to institutional theory and organizational capacity, industry and organizational-level implications are presented.

Published: November 2019

This paper focuses on the sustainability of material flow and intralogistics in factories, two of the primary keys to productivity. In the past ten years, there has been significant interest in the sustainability of intralogistics to increase productivity. The aim of this article is to investigate the consequences of combining two factories into one, followed by the design of new material flows and intralogistics from a long-term perspective and with respect to sustainability. Therefore, this paper outlines sustainability variants of new material flow solutions in factories. Our methods and approaches were chosen because they represent one of the most rapid ways to rationalise material flows and intralogistics in factories to sustain this concept. In comparison with other projects that eliminate problems in the short term, we have focused on the overall long-term and sustainable concept of intralogistics and material flows over the next 10 to 15 years. Our approach has the potential to increase productivity intralogistics and its long-term sustainability. The proposed variants were verified and evaluated using visTable®touch software (v.2.7, plavis GmbH, Chemnitz, Germany). On the basis of these results, the rational variant of material flows was chosen for the factory. This variant has the highest overall improvement of 25%, even after the implementation of factory two into factory one.
Age and Experience versus Susceptibility to Client Pressure among Property Valuation Professionals—Implications for Rethinking Institutional Framework
Authors: Małkowska Agnieszka , Uhruska Małgorzata , Tomal Mateusz
Published: November 2019

This research deals with the problem of the client–valuer relationship, possibly resulting in valuation biases. It aims to identify the influence of age and professional experience, along with other specific factors, on the perception and susceptibility of valuation professionals to pressure exerted by clients during the valuation process. We hypothesize that susceptibility to pressure from clients is conditioned by a number of factors, among which age and work experience are of key importance. The analysis is based on information obtained in a survey among Polish valuers who are members of professional associations. We used the linear probability and logit models. The conclusions of the analysis allow us to take a critical look at the existing institutional framework of the valuation profession in Poland. Our recommendations for revising the system may provide insights on the evolution of the profession, especially in Central and Eastern European countries where it is relatively new.

Published: November 2019

The aim of this study is to compare the removal of organic micropollutants (OMPs) in wastewater by activated sludge (AS) and constructed wetlands (CWs). This analysis was carried out in a wastewater treatment plant (WWTP) of a rural community where they implemented two technologies in parallel: AS and a pilot plant of horizontal subsurface flow (HSSF) constructed wetlands. In this case, these systems were fed by the same influent and the removal efficiencies of 14 OMPs, including analgesics/anti-inflammatories, anticonvulsants, stimulants, antifungals, fragrances, plasticizers, and transformation products, were evaluated in each system. Regarding the presence of OMPs in the wastewater, the concentrations of these compounds in the influent ranged from 0.16 to 7.75 µg/L. In general, the removal efficiencies achieved by the AS system were between 10%–95% higher than those values reported by HSSFs with values above 80% for naproxen, ibuprofen, diclofenac, caffeine, triclosan, methyl dihydrojasmonate, bisphenol-A, 2-hydroxyl ibuprofen, and carboxy ibuprofen (p < 0.05). This behavior can be related to the aerobic conditions that promote the AS system with oxidation-reduction potential (ORP) and dissolved oxygen (DO) values above −281 mV and 0.24 mg/L, respectively. However, the removal of galaxolide was greater in HSSF system than in AS with significant difference of 70% (p < 0.05). Despite these results, this study reveals that comparing both technologies, AS had the best removal performance of these OMPs studied.

Oily wastewater from shipping waste and marine accidents have seriously polluted the marine environment and brought great harm to human production and health. With the increasing awareness of environmental protection, the treatment of marine oily wastewater has attracted extensive attention from the international community. Marine oily wastewater has various forms and complex components, so its treatment technology faces great challenges. Sources, types, supervision, and treatment of marine oily wastewater are introduced in this paper. The research progress of marine and ship’s oily wastewater treatment technologies in recent years are reviewed from the perspectives of physical treatment, chemical treatment, biological treatment, and combined treatment, respectively. Principles and characteristics of all kinds of technologies were analyzed. In addition, this paper shows that multiple processing technologies used in combination for the purpose of high efficiency, environmental protection, economy, and energy conservation are the future development trend.
WALL SILICATE MATERIALS OF NON-AUTOCLAVE HARDENING WITH THE USE OF SILICA RAW MATERIALS AND ALUMINOSILICATE BINDING BASED ON NON-CONVENTIONAL CLAY ROCKS
Authors: Володченко А. , Volodchenko A.
Published: November 2019

Among the used building materials, structural autoclave silicate products occupy one of the leading places. The traditional technology of silicate materials uses autoclave processing of products, the main disadvantage of which is the high energy intensity. In order to create non-autoclave silicate composites based on conventional siliceous raw materials, it is proposed to use a special aluminosilicate binder based on clay rocks of the incomplete stage of mineral formation of a certain genesis and quicklime. The strength of silicate materials is growing as a result of the neoplasm process. They are synthesized in the chemical reaction of quicklime with components of clay rocks when using high pressure and temperature modes in an autoclave, and when steaming with temperatures up to 100 °C. The high specific surface of the aluminosilicate binder provides an increase in the packing density of the material. Due to the structural features of the CaO-SiO2 (Al2O3)-H2O system based on unconventional clay rocks, the process of formation of the microstructure of the material, which continues and after hydrothermal treatment of the products, gives the material hydraulic properties. The proposed binders and their production technologies can be implemented in small and medium-sized businesses, which will allow to obtain competitive non-autoclave silicate materials with a compressive strength of up to 25 MPa and an average density of 1850 kg/m3.

Prefabricated reinforced concrete structures are widely used to speed up the erection of structures in construction practice; they are connected during installation by means of embedded core elements, subsequently monolithic with concrete. Under the influence of external loads, axial tensile and transverse shear forces arise in such nodal joints, which are often neglected in the static analysis of structures. In turn, this can lead to the development of ultimate deformations in the assembly, to a change in the conditions for fixing the structure, and, as a consequence, to their premature collapse. This article discusses the effect of the axial pulling force in the reinforcing bar on the stress-strain condition (VAT) of the concrete mass surrounding it. To solve this problem, a numerical experiment is carried out in the ANSYS 19.0 Workbench package, in which the adhesion of fiberglass and metal reinforcement to concrete is simulated. It allows establishing the nature of the stress distribution in the core embedment area.

Les Patrons des Poètes de la fin du Moyen Age, dans le Nord du Pays de Galles.

La conquête du Gwynedd par le roi Edouard Ier en 1282-3 a signifié la fin d’une longue tradition de poésie de cour galloise. La fonction de mécène des princes fut reprise par les puissantes familles qui avaient dominé leur propre classe, et qui continuèrent à ce faire sous le nouveau régime. L’apparition de nouvelles familles de propriétaires terriens à partir du XIVe siècle étoffa une classe sociale dont les poètes eux-mêmes étaient issus. L’auteur examine à quels types d’hommes appartiennent les patrons des poètes, qui entretenaient la tradition poétique indigène à la fin du Moyen Age, et quel fut leur rôle dans la société de leur temps.
Emprunts français dans un parler breton de Haute-Cornouaille finistérienne (Poullaouen - 29246)
Authors: Favereau Francis
Published: November 2019

French loanwords in a Breton dialect of Haute Cornouaille (Poullaouen, Finistère).

The French influence on Middle Breton and further stages is well known. Breton lexicographers, on the other hand, have been prone to practise a «Celtic purism» from the beginning of the XIXe c. on to our times. But what about the situation in the oral usage, and particularly in the language of Poullaouen and of Poher (which the author has studied in his thesis) ?

After a short lexical analysis, it has been possible to propose a numeric estimation and to sketch a (fragmentary but significant) comparison with existing dictionaries, and even with current Breton handbooks, before reaching a conclusion about educational problems and this different question, which is, the new standard required by media.
On the origin of the 5-years cycle in the Celtic Calendar
Authors: Parisot Jean-Paul
Published: November 2019

L’origine de la période de cinq ans dans le Calendrier de Coligny.

Le Calendrier connu sous le nom de “calendrier gaulois de Coligny” se compose de 2 fragments découverts dans l’est de la France au siècle dernier : dans le lac d’Antre (Jura) et un ensemble plus complet trouvé à Coligny (Ain). Ce dernier se présente sous la forme d’une grande table de bronze qui comporte environ 2000 termes (60 mots différents) dont le sens reste pour la plupart obscur. En dépit de nombreuses lacunes, une reconstitution a été possible grâce à de minutieux travaux. Le calendrier se compose de 5 années consécutives formées de 62 mois de 29 ou 30 jours constituant un ensemble de 1835 jours. La correspondance entre le rythme des saisons (365.2424 jours) et la révolution de la lune (29.5306 jours) était assurée par l’intercalation de 2 mois supplémentaires de 30 jours placés l’un au début de la première année et l’autre au milieu de la troisième. En appliquant au calendrier de Coligny une méthode mathématique très simple basée sur la décomposition en fractions continues nous pouvons montrer que ce cycle de 5 ans découle naturellement d’un ajustement luni-solaire et qu’il ne constitue qu’une solution parmi beaucoup d’autres de l’harmonisation des cycles lunaires et solaires.

The tree with rotteness.

Celticist have long debated about the documentary value of the so-called Bern scholies added to a Lucan text, and particularly of Celtic human sacrifices mentioned in them. The discussion about the sacrifice made to the god Esus has been hindered by the poverty of Gallo-roman evidence concerning this god. A comparison with Insular medieval material permits — as it often happens — a decisive progress on that question, and lead us to favour the theory of the authenticity for the Bern scholies.

La prétendue belle-sœur de couleur de l'abbé Grégoire. Une homonymie, cause de la bourde de Massiac ?
Authors: Piquet Jean-Daniel
Published: November 2019

In 1 790 the allegation against the Abbé Grégoire from the Club Massiac to fight for Mullatoes rights because of a sister-in law is wrong but not necessarily lying. Henri Grégoire was only son but he had an Homonym, Louis-Chrisostôme Grégoire, a young vicar in Villers-Cotterêts who was equally a constitutionnal priest. By a great friendship with Dumas family, he respected mixed mariage and as opposed to Henri Grégoire had a brother able to be married. Also, this information varies a few interpretations about general rejection of cross-breeding by French revolutionnary party.
Teacher and Servant

In the early days of research on the Dead Sea Scrolls, several scholars argued that the Teacher of Righteousness understood himself as the Servant of Isaiah's prophecies. While this view has long been rejected, it has now been revived by Michael Wise. Examination of the evidence leads to the conclusion that the Teacher did indeed draw on the Servant poems in his self-presentation, but did not identify himself as the Servant in any messianic sense.

Recently, multivalent aqueous calcium-ion batteries (CIBs) have attracted considerable attention as a possible alternative to Li-ion batteries. However, traditional Ca-ion storage materials show either limited rate capabilities and poor cycle life or insufficient specific capacity. Here, we tackle these limitations by exploring materials having a large interlayer distance to achieve decent specific capacities and one-dimensional architecture with adequate Ca-ion passages that enable rapid reversible (de)intercalation processes. In this work, we report the high-yield, rapid, and low-cost synthesis of 1D metal oxides

Robust signal transfer in the form of electromagnetic waves is of fundamental importance in modern technology, yet its operation is often challenged by unwanted modifications of the channel connecting transmitter and receiver. Parity-time- (PT-) symmetric systems, combining active and passive elements in a balanced form, provide an interesting route in this context. Here, we demonstrate a PT-symmetric microwave system operating in the extreme case in which the channel is shorted through a small reactance, which acts as a nearly impenetrable obstacle, and it is therefore expected to induce large reflections and poor transmission. After placing a gain element behind the obstacle, and a balanced lossy element in front of it, we observe full restoration of information and overall transparency to an external observer, despite the presence of the obstacle. Our theory, simulations, and experiments unambiguously demonstrate stable and robust wave tunneling and information transfer supported by PT symmetry, opening opportunities for efficient communication through channels with dynamic changes, active filtering, and active metamaterial technology.

Perbandingan Teknik Reduksi Derau Speckle Pada Citra Ultrasonograpi Payudara
Authors: Triyani Yuli , Rahmawaty Made
Published: November 2019

Kanker payudara merupakan kanker dengan angka kejadian, jumlah kasus baru dan tingkat kematian tertinggi bagi perempuan di Indonesia dan dunia. Pemeriksaan ultrasonografi (USG) direkomendasikan untuk kanker payudara, karena nyaman, tanpa radiasi dan dapat digunakan secara luas.  Namun citra USG sering mengalami degradasi atau penurunan kualitas yang disebabkan oleh derau spekcle yang sering terjadi pada saat akuisisi citra. Hal ini menyulitkan ahli radiologis ataupun sistem Computer Aided Diagnosis (CAD) dalam mendiagnosis citra tersebut. Beberapa teknik reduksi derau spekcle telah diusulkan. Jurnal ini bertujuan untuk membandingkan kinerja 14  teknik reduksi derau spekcle pada citra USG payudara. Pengujian dilakukan secara kuantitatif terhadap 58 citra USG payudara dan 3 citra artificial USG payudara. Parameter kuantitatif yang digunakan meliputi analisis tekstur (Mean, Varian, skewness, kurtosis, kontras dan entropi) dan evaluasi kualitas citra (MSE, RMSE, SNR, SSIM, Structural content dan Maximum Difference). Pengujian secara kualitatif juga dilakukan berupa penilaian dari 3 orang dokter spesialis radiologi terhadap 3 sampel hasil setiap teknik reduksi. Berdasarkan hasil pengujian yang telah dilakukan, 3 filter dengan kinerja terbaik adalah DsFsrad, DsFamedian dan DsFhmedian.

Educação feminina no Brasil e em Portugal: um passo para a feminização do magistério
Authors: Rabelo Amanda Oliveira
Published: November 2019

Este artigo apresenta um histórico de como a educação feminina foi tratada desde o período da colonização do Brasil por Portugal até os dias atuais e de como esta se relacionou com a feminização do magistério primário. Apresentaremos um esboço de algumas abordagens teóricas sobre história da educação, elegendo bibliografias de ambos os países que fizessem análises históricas com escolhas documentais alargadas e/ou diferenciadas, que deram ênfase também à análise das narrativas e dos discursos, bem como buscamos algumas fontes oficiais e dados estatísticos. Deste processo, concluímos que a forma como a escolarização feminina iniciou-se foi um dos primeiros passos para que acontecesse a feminização do magistério.
