Beyond the Power and Control Wheel: how abusive men manipulate mobile phone technologies to facilitate coercive control
Authors: Havard Tirion Elizabeth , Lefevre Michelle
Published: April 2020

Mobile phone ownership has become almost universal, with smartphones the most popular consumer electronics device. While the role of technologies and digital media in the domestic abuse of women is gaining international attention, specific information regarding how mobile phones, and their various ‘apps’, may assist perpetrators in the coercive control of their current or former partners is still a relatively unexplored area in the research literature. This study with women survivors was able to identify that perpetrators use mobile phones in ways that go beyond the traditional tactics of abuse identified through the globally used feminist theorisation of the Power and Control Wheel (developed by the Duluth Domestic Abuse Intervention Programme). The portability and diverse capabilities of mobile phones have been manipulated by abusive men to develop strategies of ‘agile technological surveillance’, which allow them to track and monitor their partners in various ways ‘on the go’ and irrespective of physical proximity. An adaptation of the Power and Control Wheel has been developed and licensed to account for these new opportunities for surveillance, manipulation and control. Proposals are made for integrating this revised framework into professional practice to inform the assessment and management of risk in abusive relationships.
Real-time en-face Gabor optical coherence tomographic angiography on human skin using CUDA GPU
Authors: Chen Chaoliang , Shi Weisong , Yang Victor X. D.
Published: April 2020

We recently proposed an optical coherence tomographic angiography (OCTA) algorithm, Gabor optical coherence tomographic angiography (GOCTA), which can extract microvascular signals from a spectral domain directly with lower computational complexity compared to other algorithms. In this manuscript, we combine a programmable swept source, an OCT complex signal detecting unit, and graphics process units (GPU) to achieve a real-time en-face GOCTA system for human skin microvascular imaging. The programmable swept source can balance the A-scan rate and the spectral tuning range; the polarization-modulation based complex signal detecting unit can double the imaging depth range, and the GPU can accelerate data processing. C++ and CUDA are used as the programming platform where five parallel threads are created for galvo-driving signal generation, data acquisition, data transfer, data processing, and image display, respectively. Two queues (for the raw data and en-face images, respectively) are used to improve the data exchange efficiency among different devices. In this study, the data acquisition time and data processing time for each 3D complex volume (256×304×608 pixels,) are 405.3 and 173.7 milliseconds respectively. To the best of our knowledge, this is the first time to show en-face microvascular images covering 3×3 mm2 at a refresh rate of 2.5 Hz.
Graphene-based wavelength demultiplexing structure
Authors: Deng Guangsheng , Zhao Tianxiang , Yin Zhiping , Yang Jun
Published: April 2020

A wavelength demultiplexing (WDM) structure based on graphene nanoribbon resonators is proposed and simulated using the finite-difference time-domain (FDTD) method. Based on a simple structure, the demultiplexing wavelength and transmission characteristics of the WDM can be tuned by adjusting the length of the resonator, the nanoribbon width, or the chemical potential of graphene within a relative broadband frequency range. Moreover, the mechanism of the proposed WDM structure is analyzed in detail using the theory of Fabry–Perot (F-P) resonance and temporal coupled-mode theory. The proposed structure has promising potential in the field of ultracompact WDM systems in highly integrated optical circuits.

Published: April 2020

This work demonstrates the efficiency of machine learning in the correction of spectral intensity variations in laser-induced breakdown spectroscopy (LIBS) due to changes of the laser pulse energy, such changes can occur over a wide range, from 7.9 to 71.1 mJ in our experiment. The developed multivariate correction model led to a precise determination of the concentration of a minor element (magnesium for instance) in the samples (aluminum alloys in this work) with a precision of 6.3% (relative standard deviation, RSD) using the LIBS spectra affected by the laser pulse energy change. A comparison to the classical univariate corrections with laser pulse energy, total spectral intensity, ablation crater volume and plasma temperature, further highlights the significance of the developed method.
SPADnet: deep RGB-SPAD sensor fusion assisted by monocular depth estimation
Authors: Sun Zhanghao , Lindell David B. , Solgaard Olav , Wetzstein Gordon
Published: April 2020

Single-photon light detection and ranging (LiDAR) techniques use emerging single-photon detectors (SPADs) to push 3D imaging capabilities to unprecedented ranges. However, it remains challenging to robustly estimate scene depth from the noisy and otherwise corrupted measurements recorded by a SPAD. Here, we propose a deep sensor fusion strategy that combines corrupted SPAD data and a conventional 2D image to estimate the depth of a scene. Our primary contribution is a neural network architecture—SPADnet—that uses a monocular depth estimation algorithm together with a SPAD denoising and sensor fusion strategy. This architecture, together with several techniques in network training, achieves state-of-the-art results for RGB-SPAD fusion with simulated and captured data. Moreover, SPADnet is more computationally efficient than previous RGB-SPAD fusion networks.
Subpicosecond light pulses induced by Fano antiresonance buildup process
Authors: Friman A. V. , Shubin N. M. , Kapaev V. V. , Gorbatsevich A. A.
Published: April 2020

We propose a simple technique of cutting short pulses out of a sharp edge input signal. The technique is based on the Fano antiresonance buildup dynamics. The output pulse duration is inverse proportional to the coupling strength to the resonator. We show that this coupling can be effectively increased by using more than one resonator and exploiting the antiresonance coalescence phenomenon. Analytical calculations for a model of standing-wave resonators and whispering gallery mode (WGM) resonators are performed within the coupled mode theory. We show that the latter can provide better pulse compression. Analytical results for WGM resonators are verified numerically by finite difference time domain method. Ability to generate pulses as short as a few hundreds of femtoseconds at 1.55 μm wavelength has been demonstrated for a potentially CMOS compatible silicon waveguide, which does not require optical nonlinearities to operate.
Teaching optics to a machine learning network
Authors: Blanchard-Dionne André-Pierre , Martin Olivier J. F.
Published: April 2020

In this Letter, we demonstrate how harmonic oscillator equations can be integrated in a neural network to improve the spectral response prediction for an optical system. We use the optical properties of a one-dimensional nanoslit array for a practical implementation of the study. This method allows to build more generalizable relations between the input parameters of the array and its optical properties, showing a 20-fold improvement for parameters outside the range used for the training. We also show how this model generates the output spectrum from phenomenological relationships between the input parameters and the output spectrum, indicating how it grasps the physical mechanisms of the optical response of the structure.
Increased SNR in acousto-optic imaging via coded ultrasound transmission
Authors: Levi Ahiad , Monin Sagi , Hahamovich Evgeny , Lev Aner , Sfez Bruno G. , Rosenthal Amir
Published: April 2020

Acousto-optic imaging (AOI) is a non-invasive method that uses acoustic modulation to map the light fluence inside biological tissue. In many AOI implementations, ultrasound pulses are used in a time-gated measurement to perform depth-resolved imaging without the need for mechanical scanning. However, to achieve high axial resolution, it is required that ultrasound pulses with few cycles are used, limiting the modulation strength. In this Letter, we develop a new approach to pulse-based AOI in which coded ultrasound transmission is used. In coded-transmission AOI (CT-AOI), one may achieve an axial resolution that corresponds to a single cycle, but with a signal-to-noise ratio (SNR) that scales as the square root of the number of cycles. Using CT-AOI with 79 cycles, we experimentally demonstrate over four-fold increase in SNR in comparison to a single-cycle AOI scheme.

‘Turn back from this cave’: The weirdness of Beginner’s Guide
Authors: Moulthrop Stuart
Published: April 2020

This article pursues a deep dive into various enigmas presented by Davey Wreden's second effort, The Beginner's Guide (2015), moving beyond the vexed question of whether the work can count as a game to the perhaps more interesting subject of how the work intervenes in game culture and what it says about the nature of game poetics. The ultimate focus is on the structure of the game, especially in its adoption of a logic of coda, to which the article relates the Derridean notion of supplement.
Unearthing the political unconscious in the reporting of homelessness in Manchester
Authors: Broady Rachel
Published: April 2020

Journalists in Manchester have reported on homelessness with the intention of highlighting a problem, persuading a charitable response and encouraging legislative intervention. They serve as the way for readers, who may not spend time among the homeless, to observe and understand. This article argues that the representation is restricted by the ideological arena in which journalists work. It posits that by utilizing Fredric Jameson’s interpretive horizons methodology, the political unconscious of copy can be unearthed to reveal the acceptance of the inevitability of homelessness, which has been internalized and reconfigured in stories about the topic. It argues that it is possible to reveal the strategies of containment unconsciously employed, which conceal the relationship between labour and value, and ultimately defend the status quo, despite the intentions of journalists and publications. It further posits that the systemic, societal causes of homelessness are ultimately unchallenged, with the experience unconsciously mediated by the journalists and shared with an audience treated as fellow observers.

A transversalização da Educação Ambiental no currículo do curso de Oceanologia: uma análise a partir da Proposta Metodológica de Ambientalização Curricular - PMAC
Authors: Da Silva Isis Torales , Kitzmann Dione
Published: April 2020

Entre as áreas que integram as Ciências do Mar, a Oceanografia é considerada a mais antiga e tradicional. Em sua vertente Clássica, toma por base os quatro ramos temáticos (Biologia, Química, Geologia e Física) do ambiente marinho e costeiro e das suas zonas de transição. Contudo, é reconhecível a carência do componente social como um dos eixos temáticos do campo. Desta forma, apresentamos neste artigo uma alternativa para contribuir na reversão desse cenário, através da implementação da PMAC – Proposta Metodológica de Ambientalização Curricular (MOTA & KITZMANN, 2018) no currículo do curso de Oceanologia da Universidade Federal do Rio Grande, para que, por meio da transversalização dos princípios e fundamentos da Educação Ambiental, ambientalize-se o currículo do curso de forma a inserir interdisciplinarmente o componente social.

Authors: Nascimento Daniel Dalvan do , Vidal Roberta Luiza , Pimenta Anderson Alves , Costa Marilia Gregolin , Soares Pedro Luiz Martins
Published: April 2020

The relationship of crops grown in rotation or in succession has increased every day and the use of antagonistic plants and/or non-host plants is one of the most efficient practices of integrated management of nematodes. This study aimed to evaluate the efficiency of crotalaria (Crotalaria spectabilis Roth) and millet [Pennisetum glaucum (L.) Leeke] ‘ADR 300’ in reducing the population of Meloidogyne incognita and M. javanica and in increasing the productivity of okra [Abelmoschus esculentus (L.) Moench] when cultivated in succession. The experiment was conducted in an area cultivating okra (host culture) in rotation, with a history of severe infestation by phytonematoids. The experimental design involved randomized blocks with six treatments and four replicates, with the following treatments: T1, 15 kg.ha-1 of millet seeds; T2, 30 kg.ha-1 of crotalaria; T3, 10 kg.ha-1 of millet + 20 kg.ha-1 of crotalaria; T4, 20 kg.ha-1 of millet + 6 kg.ha-1  of crotalaria; T5, 6 kg.ha-1 of millet + 36 kg.ha-1 of crotalaria; and T6, control. The nematode populations in the soil and roots were evaluated about 60 d after planting okra, and the yield was evaluated at the end of the crop cycle. Simple treatment with millet or crotalaria reduced the nematode population by 61% and 72%, respectively. The millet-crotalaria intercropping treatments reduced the nematode population by up to 85% compared with the control. In terms of productivity, there was an increase of 787 kg.ha-1 in the millet treatment and 2,109 kg.ha-1 in the intercropping treatments. Both the single cultivation of crotalaria or millet and the consortia of crotalaria and millet were effective in controlling the root-knot nematodes, and increased the productivity of okra.

Published: April 2020

This study aimed to evaluate the occurrence of canine leptospirosis and the possible risk factors associated with the disease in the municipality of Patrocínio, MG, Brazil. A cross-sectional observational study was carried out from July through August 2017.  The municipality was divided into four regions (north, south, east and west) and a predefined number of neighborhoods (25) were randomly sampled in each region. Samples of blood serum were collected from 241 domiciled male and female dogs of different breeds and ages. To investigate the risk factors for canine leptospirosis, the owners of the animals were asked to fill out an epidemiological questionnaire. The following factors were evaluated: breed, sex, age, presence of rodents, type of diet, access to the street, vaccination, presence of flooded areas, and educational level of the owners. Blood serum samples were evaluated by the Microscopic Agglutination Test (MAT), using a collection of 24 live antigens. Of the 241 dogs evaluated, 32 (13.2%) were reactive. The most frequent serovars were: Copenhageni (37.5%) and Canicola (21.8%), followed by Icterohaemorrhagiae and Grippotyphosa (12.5%), Pomona, Tarassovi and Butembo (9.3%) and Hardjo (6.2%). The presence of canine leptospirosis was associated with purebred dogs (OR=0.3059 [95% CI: 0.1430 – 0.6547]) and vaccination (OR=2.581 [95% CI: 1.198 – 5.563]). It was concluded that some dogs in the municipality of Patrocínio, MG have anti-Leptospira spp. antibodies and that the serovars most frequently identified were Copenhageni (37.5%) and Canicola (21.8%). Pure breeds and vaccination were factors associated with the prevalence of infection.

Soil liming is a common practice in agriculture. It aims to reduce soil acidity and to supply calcium and magnesium. Lime, however, is not easily soluble in the soil, and its reaction products are often concentrated in the application zone, which is mainly the topsoil layer. In order to increase the concentration of nutrients in deeper layers, agricultural gypsum—a byproduct of phosphoric acid production process, rich in calcium and sulfur—is used. In this context, the objective of this study was to evaluate the chemical attributes of the oxysoil and the corn´s yield to the application of gypsum associated with potassium (K) rates. The study was developed in Uberaba city, Minas Gerais state, Brazil. The factorial scheme was used 5x5, with five rates of K (0, 100, 180, 240, 360 kg ha-1 K2O) and five gypsum rates (0, 500, 1000, 2000, 4000 kg ha-1) in a randomized complete block design with four replications. The soil chemical attributes were evaluated at 0.0-0.20 m and 0.20-0.40 m depth and the biometric and productive attributes of corn. The application of gypsum resulted in the increase of calcium (Ca) and sulfur (S) contents in all depths; reduced the levels of pH, manganese, potential acidity (H + Al) in the 0.0-0.20 m depth, and increase the levels of base of saturation and sum of bases on the 0.20-0.40 m depth. Corn yield and biometric attributes no were influenced by the factors evaluated.

Published: April 2020

The production of grafted passion fruit is an alternative for plant adaptation to saline environments. The objective of this study was to evaluate the effect of salt stress on physiology, biometry and fruit quality of P. edulis grafted on Passiflora spp. The experiment was conducted in completely randomized design, in a 3 x 2 factorial scheme, corresponding to three species of Passiflora (P. edulis, P. gibertii and P. cincinnata) with P. edulis scion and two levels of irrigation water salinity (0.5 - control and 4.5 dS m-1), with four repetitions. Water salinity compromises gas exchanges (CO2 assimilation raste and transpiration) and physiological variables (total chlorophyll and total water consumption) in grafted P. edulis. The interaction between the factors (water salinity x species) compromised only the growth in plant height and number of leaves. In relation to the species, auto-grafted P. edulis stood out from the other species, with higher internal CO2 concentration, number of leaves, stem dry mass, peel thickness, total soluble solids (TSS) of the pulp and TSS/TA ratio (titratable acidity). Auto-grafted P. edulis under saline conditions develops vital mechanisms (TSS and TSS/TA), which attenuates the effects of salt stress on the physico-chemical quality of the fruits.

Published: April 2020

Mushrooms are macrofungi that serve as a vegetarian source of protein along with various bio-active molecules of primary health importance. The activity of the bio-active molecules range from antioxidant, immunomodulation, hepatoprotection. Cultivated oyster mushrooms are also rich in these components which may be estimated quantitatively by skill intensive ‘destructive’ chemical techniques. Infra Red spectroscopy provides a non-destructive user friendly technique to quickly assess the presence of bio-active compounds in mushroom species to be used as a quality control measure as this non-destructive tool can be used to segregate mushroom harvest according to availability of bioactive compounds. IR spectra based strain classification and taxa delimitation of mushroom samples are also attempted vis a vis DNA sequence based phylogeny analysis of the same, but no correlation is observed between the two types of phylogeny analysis.

Integración entre mercados de petróleo de diferente calidad con base en las correlaciones condicionales dinámicas
Authors: De Jesús-Gutiérrez Raúl
Published: April 2020

Este artículo prueba el grado de integración de México en los mercados internacionales del petróleo a través de la evolución de las correlaciones dinámicas en periodos estables, de crisis e inestables. Las estimaciones del modelo GARCH-CCD muestran que las correlaciones son positivas y cambian con el tiempo en respuesta al origen de choques en los precios del petróleo para los periodos de relativa calma, crisis y turbulencia financiera. Asimismo, los resultados del estadístico-t y valor-p bootstrap confirman que las correlaciones son significativamente diferentes en periodos de estabilidad e inestabilidad con respecto a las correlaciones del periodo de crisis, lo que favorece la hipótesis de regionalización entre los mercados de petróleo. Los hallazgos tienen importantes implicaciones económicas y financieras para el gobierno y los consumidores.
Morpho-Anatomical, Fluorescent characteristic, Phytochemical and Antibacterial studies of Phyllanthus myrtifolius and Phyllanthus reticulatus of Kerala
Authors: James Jess Mary , P C Neethu , Antony Thomas
Published: April 2020

Two species of Phyllanthus ie P.myrtifolius and P.reticulatus were selected for their Morpho-anatomical, Fluorescent characteristic, Phytochemical and Antibacterial studies. Although the fundamental characters remained same, there were many small differences in their morpho-anatomical characters especially the colour of the fruit, the number of tepals, the outline of stem, presence of ridges and furrows, presence or absence of pith etc. The stomata was paracytic in P.myrtifolius while the stomata was anisocytic in P.reticulatus. The stem outline was rounded in P.myrtifolius while it was angular in P.reticulatus. Ridges and furrows were present in P.myrtifolius while it was absent  in P.reticulatus.  Hyaline epidermal hairs emerges out from the stem in P.myrtifolius while it was absent in P.reticulatus. Small lens shaped thick walled pith was present in P.myrtifolius while large pith was recorded in P. reticulatus. The study of their powder extracts brings to light several distinguishing characters which enable us to differentiate between the two species. Fluorescent characteristics of the plant powders were studied, but it revealed the complete absence of fluorescence in both the plant powder  extracts. Phytochemical analysis  revealed that both the plants possessed secondary metabolites which  have strong pharmacological properties and  can be utilized for medicinal purposes. P.myrtifolius less commonly used as a medicinal plant exhibited at several instances, more appreciable antibacterial results when compared to P.reticulatus against S.aureus, Pseudomonas aeruginosa, Proteus vulgaris and E coli  bacteria and produced inhibition zones of 20mm,18mm,17mm and 15mm respectively and the leaf extracts has greater antibacterial potency than either stem or root extracts.

Published: April 2020

Background

Cell-free DNA (cfDNA) is emerging as a surrogate sample type for mutation analyses. We investigated the suitability of malignant pleural effusion (MPE) and plasma as a biomaterial for analyzing epidermal growth factor receptor (EGFR) mutation by peptide nucleic acid (PNA) clamping-assisted fluorescence melting curve (PANAMutyper™) analysis.

Methods

Matched tissue, MPE cell block (MPE-CB), MPE supernatant, and plasma samples were collected from patients with advanced lung adenocarcinoma who had a MPE at the time of diagnosis. EGFR mutation was assessed by PANAMutyper™.

Results

Mutation analyses in matched tumor tissues, MPE-CB, MPE supernatant, and/or plasma samples were available for 67 patients. In comparison with tumor tissue and MPE-CB, MPE supernatant exhibited 84.4% sensitivity, 97.1% specificity, 96.4% positive predictive value (PPV), and 87.2% negative predictive value (NPV). In the same comparison, plasma exhibited 70.6% sensitivity, 100.0% specificity, 100.0% PPV, and 73.7% NPV. When sorted by mutation type, MPE supernatant had better sensitivity than plasma for the detection of two major EGFR mutations: 93.8% vs. 75.0% for exon 19 deletion and 73.3% vs. 60.0% for L858R.

Conclusions

In this cohort of patients with MPEs, MPE supernatant demonstrated superior diagnostic performance compared with plasma using a PNA-based real-time PCR method.

Published: April 2020

Background

It is not clear if point-of-care (POC) testing for hemoglobin A1c (HbA1c) is associated with glycemic control in type 2 diabetes.

Methods

In this cross-sectional study, we linked general practitioner (GP) data on 22,778 Norwegian type 2 diabetes patients to data from the Norwegian Organization for Quality Improvement of Laboratory Examinations. We used general and generalized linear mixed models to investigate if GP offices’ availability (yes/no) and analytical quality of HbA1c POC testing (average yearly “trueness score”, 0–4), as well as frequency of participation in HbA1c external quality assurance (EQA) surveys, were associated with patients’ HbA1c levels during 2014–2017.

Results

Twenty-eight out of 393 GP offices (7%) did not perform HbA1c POC testing. After adjusting for confounders, their patients had on average 0.15% higher HbA1c levels (95% confidence interval (0.04–0.27) (1.7 mmol/mol [0.5–2.9]). GP offices participating in one or two yearly HbA1c EQA surveys, rather than the maximum of four, had patients with on average 0.17% higher HbA1c levels (0.06, 0.28) (1.8 mmol/mol [0.6, 3.1]). For each unit increase in the GP offices’ HbA1c POC analytical trueness score, the patients’ HbA1c levels were lower by 0.04% HbA1c (−0.09, −0.001) (−0.5 mmol/mol [−1.0, −0.01]).

Conclusions

Novel use of validated patient data in combination with laboratory EQA data showed that patients consulting GPs in offices that perform HbA1c POC testing, participate in HbA1c EQA surveys, and maintain good analytical quality have lower HbA1c levels. Accurate HbA1c POC results, available during consultations, may improve diabetes care.
Computing Optimal Properties of Drugs Using Mathematical Models of Single Channel Dynamics

Single channel dynamics can be modeled using stochastic differential equations, and the dynamics of the state of the channel (e.g. open, closed, inactivated) can be represented using Markov models. Such models can also be used to represent the effect of mutations as well as the effect of drugs used to alleviate deleterious effects of mutations. Based on the Markov model and the stochastic models of the single channel, it is possible to derive deterministic partial differential equations (PDEs) giving the probability density functions (PDFs) of the states of the Markov model. In this study, we have analyzed PDEs modeling wild type (WT) channels, mutant channels (MT) and mutant channels for which a drug has been applied (MTD). Our aim is to show that it is possible to optimize the parameters of a given drug such that the solution of theMTD model is very close to that of the WT: the mutation’s effect is, theoretically, reduced significantly.We will present the mathematical framework underpinning this methodology and apply it to several examples. In particular, we will show that it is possible to use the method to, theoretically, improve the properties of some well-known existing drugs.

In the statistical literature, truncated distributions can be used for modeling real data. Due to error
of measurement in truncated continuous data, choosing a crisp trimmed point caucuses a fault inference, so
using fuzzy sets to define a threshold pointmay leads us more efficient results with respect to crisp thresholds.
Arellano-Valle et al. [2] defined a selection distribution for analysis of truncated data with crisp threshold. In
this paper, we define fuzzy multivariate selection distribution that is an extension of the selection distributions
using fuzzy threshold. A practical data set with a fuzzy threshold point is considered to investigate the
relationship between high blood pressure and BMI.

A trial was carried out in Mozambique in 1998-1999, with the aim to study the effect of three levels of maize-sunflower intercropping ratios (25:75, 50:50, 75:25) in comparison with the pure-stand crop of two sunflower and maize varieties. For both maize varieties yield per plant decreased in relation to density, being lowest in the pure-stand crop. This beaviour was partially true for sunflower. The intercropping 75:25 maize-sunflower ratio showed the highest seed yield per hectare (5195 kg ha-1) and the maize and sunflower LER coefficients suggested that maize is slightly dominant over sunflower in the mixture. The relative advantage of the two species in respect to the single crop stand was about 16 and 19%. However each species and variety reached its maximum yield per hectare when it was grown as pure stand crop (100%). On the other side, when yield is examined in terms of food energy (K-calories), given by maize grain and sunflower protein and oil per hectare, maize-sunflower 75:25 mixture ratio appears to be much more convenient and suitable for food supply even when compared with the maize pure crop stand. The increase in K-calories is 380 ha-1 and the better balance in carbohydrates, proteins and lipids can assure sustainability to standard farm families as those living in Mozambique. Using sunflower oil, a quite good amount of unsaturated fatty acids and lyposoluble vitamins are also supplied in the diet of farming people.

Moderne Desktop- und mobile Plattformen bieten dem Benutzer die Möglichkeit, Aspekte der Präsentation und der Interaktion individuell zu konfigurieren, um damit die Benutzerschnittstelle zu personalisieren. Allerdings gibt es dazu kaum plattformübergreifende Lösungen. Dies benachteiligt insbesondere Benutzer mit Behinderungen und ältere Benutzer, die oft eine Vielzahl von Anpassungen vornehmen müssen, um ein System ohne Barrieren bedienen zu können, und die sich meist nicht genügend auskennen, um die für sie optimale Konfiguration einzustellen. Die “Global Public Inclusive Infrastructure” (GPII), eine weltweite Open-Source-Initiative, möchte dieses Problem lösen. Dieser Artikel beschreibt den GPII-Ansatz zur Personalisierung von Benutzerschnittstellen, insbesondere die Verwendung von plattformübergreifenden Benutzerprofilen zur Einstellung der Benutzerschnittstelle, und regelbasierte und statistische Ansätze zum Matchmaking. Der GPII-Ansatz wurde in einem ersten Benutzertest vorläufig validiert.
A comparison of Newtonian and non-Newtonian models for pulsatile blood flow simulations

Published: April 2020

Mathematical modeling of blood flows in the arteries is an important and challenging problem. This study compares several non-Newtonian blood models with the Newtonian model in simulating pulsatile blood flow through two three-dimensional models of an arterial stenosis and an aneurysm. Four non-Newtonian blood models, namely the Power Law, the Casson, the Carreau, and the Generalized Power Law, as well as the Newtonian model of blood viscosity, are used to investigate the flow effects induced by these different blood constitutive equations. The aim of this study is three-fold: firstly, to investigate the variation in wall shear stress in an artery with a stenosis or aneurysm at different flow rates and degrees of severity; secondly, to compare the various blood models and hence quantify the differences between the models and judge their significance; and lastly, to determine whether the use of the Newtonian blood model is appropriate over a wide range of shear rates.

Published: April 2020

The modest aim of this short article is to provide some new results for a screw dislocation in a functionally graded material within the theory of gradient elasticity. These results, based on a displacement formulation and the Fourier transform technique, complete earlier findings obtained with the stress function method and extends them to the case of the second strain gradient elasticity. Rigorous and easy-to-use analytical expressions for the displacements, strains, and stresses are obtained, which are free from singularities at the dislocation line.

Published: April 2020

Magnetic field assisted electrical discharge machining (MFAEDM) is the modification of in conventional EDM process by use of magnetic field on EN-31. This article explain the application of response surface methodology to analyzes the effect of various process parameters such as Ton, Toff and Ip on performance measures such as material removal rate (MRR), electrode wear rate (EWR) and overcut (OC). Analysis of variance was used to check the adequacy of response surface model and significance of process parameters on performance measures. Multi-objective desirability function has been applied to obtain the optimal process parameter settings. Thereafter, machined surface of EN-31 characterized through SEM and EDX. The novelty of this paper is to improve the strategies for flushing the debris which remain clogged in standard EDM in-between machining gap that will interrupts the regular discharge conditions and reduces cutting rate as well as deteriorate the surface characteristics.

Published: April 2020

Introduction. The population of younger people having strokes is growing. Persons who are younger and have a stroke have specific stressors after a stroke that those over 60 may not experience (e.g., ability to earn an income, provide for a family, returning to work, etc.).Aim. In order to address some of these age-specific stressors, new and novel approaches to stress mediation are needed. In order to address this gap in the literature this study piloted a mindfulness meditation with younger in hospital stroke survivors.Material and Methods. Prospective non-randomized pilot study of in-hospital stroke patients < 60 years of age. Baseline assessment included the Perceived Stress Scale (PSS), heart rate (HR), blood pressure (BP), and respiratory rate (RR). Patients received a 10-minute mindfulness training session with instructions for home use. PSS, HR, BP, and RR were collected immediately after training and telephone assessments of PSS were collected 30-day post discharge.Results. The mean age of the 21 patients included in the final analysis was 47.4 years. Paired t-test showed statistically significant differences in heart rate (p < 0.001) and respiratory rate (p < 0.001) before and after the intervention, but no statistically significant differences in pre and post training blood pressure (p = 0.480). There was no statistically significant difference in PSS scores before and after the training.Conclusions. The findings of this study suggest that the mindfulness intervention is feasible for in-hospital stroke patients and shows promise for reducing stress, as indicated by physiologic changes such as lowering heart and blood pressure rates.

Published: April 2020

Social aggression, such as domestic violence, has been associated with a reduced ability to take on others’ perspectives. In this naturalistic imaging study, we investigated whether training human participants to take on a first-person embodied perspective during the experience of domestic violence enhances the identification with the victim and elicits brain activity associated with the monitoring of the body and surrounding space and the experience of threat. We combined fMRI measurements with preceding virtual reality exposure from either first-person perspective (1PP) or third-person perspective (3PP) to manipulate whether the domestic abuse stimulus was perceived as directed to oneself or another. We found that 1PP exposure increased body ownership and identification with the virtual victim. Furthermore, when the stimulus was perceived as directed toward oneself, the brain network that encodes the bodily self and its surrounding space was more strongly synchronized across participants and connectivity increased from premotor cortex (PM) and intraparietal sulcus towards superior parietal lobe. Additionally, when the stimulus came near the body, brain activity in the amygdala (AMG) strongly synchronized across participants. Exposure to 3PP reduced synchronization of brain activity in the personal space network, increased modulation of visual areas and strengthened functional connectivity between PM, supramarginal gyrus and primary visual cortex. In conclusion, our results suggest that 1PP embodiment training enhances experience from the viewpoint of the virtual victim, which is accompanied by synchronization in the fronto-parietal network to predict actions toward the body and in the AMG to signal the proximity of the stimulus.
