EDUCAÇÃO INCLUSIVA: DIFERENÇAS COMO POSSIBILIDADES (DA TEORIA À PRÁTICA)
Authors: Rosa Luiz Carlos Mariano da
Published: July 2016

Detendo-se na questão que envolve a educação inclusiva, a investigação recorre à noção de diversidade para caracterizar um processo que se impõe como a afirmação do direito à diferença e demanda a adequabilidade das estruturas socioculturais no sentido de possibilitar o cumprimento da legislação. Legislação esta que, não se restringindo ao âmbito da instituição escolar e do sistema educacional que as compõe, mas tendo-o como fundamento, converge para construir as disposições necessárias para viabilizar a condição de cidadania para os portadores de deficiência, transtornos globais do desenvolvimento e altas habilidades ou superdotação, entre outros problemas que representam um grau de dificuldade no tocante à adaptação ao arcabouço social. Isso afeta desde a relação de ensino e aprendizagem até o exercício da atividade profissional e requer não menos do que a descoberta, mas a utilização e a ampliação das suas potencialidades, tanto quanto, em suma, a emergência das suas aptidões.

O CASAMENTO E A RECIPROCIDADE NAS RELAÇÕES SEXUAIS EM KANT
Authors: Scherer Berta Rieg
Published: July 2016

O objetivo deste trabalho é desenvolver uma reflexão acerca do casamento e o conceito de reciprocidade nas relações sexuais com base na teoria moral e de ação kantiana. Entre outras questões objetiva-se responder o que caracteriza a moralidade de uma relação sexual, ou seja, quando uma relação sexual constitui-se como uma ação moral. Pretende-se mostrar que, para Kant, o casamento é uma condição necessária, mas não suficiente para que a relação sexual constitua-se como uma ação moral. Também nos referimos ao entendimento de Kant sobre a mulher e as implicações que decorrem dessa visão em relação a sua teoria moral.

OS NÚCLEOS DE EDUCAÇÃO, PREVENÇÃO, ATENÇÃO E ATENDIMENTO ÀS VIOLÊNCIAS NA ESCOLA COMO RESPOSTA AOS DESAFIOS DA DIVERSIDADE: OS 10 ANOS DA LEI 10.639/03
Authors: Lostada Lauro Roberto
Published: July 2016

No contexto das comemorações pelos 10 anos da Lei 10.639/03, que inseriu o debate sobre a história e a cultura afro-brasileira nas escolas do país, observa-se, com grande expectativa, a consolidação de um projeto capaz de agir no sentido de promover esse debate nas escolas. Considera-se, portanto, que os Núcleos de Educação, Prevenção, Atenção e Atendimento às Violências na Escola constituem-se atualmente como um poderoso instrumento na tentativa de consolidar um trabalho de remissão das dívidas historicamente acumuladas contra os povos etnicamente desprestigiados pela cultura colonialista que constituiu nossa identidade enquanto nação. Assim, apoiados em uma perspectiva multiculturalista, tem-se a concepção de que é possível elaborar um plano de ação para cada realidade, respeitando suas peculiaridades, com o objetivo de resgatar os grupos minoritários através de ações afirmativas que, aos poucos, devem ser substituídas por uma verdadeira cultura da diversidade.

“NÃO, NÃO MATE A BRUXA! ELA É NOSSA AMIGUINHA!”: ENTRADA, ACEITAÇÃO E PARTICIPAÇÃO NA CULTURA DE PARES EM UMA EXPERIÊNCIA DE ESTÁGIO SUPERVISIONADO EM EDUCADÇÃO INFANTIL
Authors: Haddad Lenira , Santos Luana Maria Moreira dos
Published: July 2016

Este artigo reflete sobre os caminhos percorridos por uma estagiária do curso de Pedagogia da UFAL para alcançar a condição de adulto atípico, termo utilizado por Corsaro (2005) para se referir a uma postura não adultocêntrica de adentrar o universo infantil. A reflexão contempla tanto as estratégias adotadas como os equívocos cometidos durante os episódios de brincadeira. É realizada com base em análise de seis episódios de brincadeira recortados do relatório de estágio, que registra o desenvolvimento de um projeto de intervenção com uma turma de crianças de 3 a 4 anos em uma instituição de Educação Infantil da universidade (SANTOS, 2013). Para a sua fundamentação teórica são utilizados os estudos de Corsaro (2005, 2011) e Brougère (1998, 2008). Os episódios evidenciam como, aos poucos, as crianças inserem a estagiária em suas ações e a aceitam como adulto atípico, permitindo que ela participe de suas rotinas de brincadeiras e comungue de suas culturas de pares.
Graphical Diagnostic for Mortality Data Modeling
Authors: Gamiz M.L. , Martinez-Miranda M.D. , Raya-Miranda R.
Published: July 2016

The main contribution of this paper is to develop a graphical tool to evaluate the suitability of a candidate parametric model to fit a data set. The practical motivation is to check the adequacy of the so called SAINT model proposed in Jarner and Kryger (2011). This model has been implemented in practice by an important European pension fund concerned with setting annuity reserves for all current or former employees of Denmark. So, one particular relevant question is whether this mortality model is actually fitting old-age. Our graphical test can be described as follows. First we transform the data by means of the parametric model which is being evaluated. Should the model be correct, the transformed data will be in accordance with an Exponential distribution with rate 1. Then we construct a family of local linear hazard estimates based on the data on the transformed scale. Finally we use the statistical tool SiZer to assess the goodness-of-fit of the Exponential distribution to the data on the transformed scale. If the model is correct the SiZer map should not reveal any significant feature in the family of kernel estimates. Our method allow us to establish a diagnostic regarding the validity of the SAINT model when describing mortality patterns in four different countries.

Pseudokinetic Model for Field-Scale Simulation of In-Situ Combustion
Authors: Mercado Diana , Trevisan Osvair V.
Published: July 2016

Chemical reactions of the in-situ-combustion (ISC) process take place in a thin zone of less than a meter thick. Numerical simulations at the field scale typically use gridblocks that are at least two orders of magnitude greater than that. Such divergence leads to improper representations of key aspects of the process, such as the temperature distribution and the reaction kinetics. In accordance with that, the reaction occurrence is not controlled by the activation energy in the simulation models. The major shortcoming is on fuel deposition, a key issue in ISC. In the simulator, the cracking reaction may proceed slowly at initial reservoir temperature, generating coke from the beginning of the simulation job.

The main focus of the paper is on a new pseudokinetic model to improve the representation of the combustion-zone effects and the fuel consumption in the field-scale ISC simulation. Along with the development of the pseudokinetic model, remedies are proposed for some shortcomings of the current reservoir simulation of ISC. The model allows maintaining the dependence of reaction rate with temperature through the use of appropriate activation-energy values. Furthermore, the model reduces the temperature-distribution effect by controlling the reaction rate on the basis of average-temperature values observed in the field-simulation model.

Published: July 2016

Patient-reported outcomes (PROs) are reports of the status of a patient's health condition that come directly from the patient. While PRO measures are a well-developed technology with robust standards in research, their use for informing healthcare decisions is still poorly understood. We review relevant examples of their application in the provision of healthcare and examine the challenges associated with implementing PROs in clinical settings. We evaluate evidence for their use and examine barriers to their uptake, and present an evidence-based framework for the successful implementation of PROs in clinical practice. We discuss current and future developments for the use of PROs in clinical practice, such as individualized measurement and computer-adaptive testing.
Demand-Sensitive Candidate Route Generation Algorithm
Authors: Davanzo Elis Reny A. , Idris Ahmed Osman
Published: July 2016

Demand satisfaction is a key component that reflects the quality of public transit from the passenger’s perspective, whereas cost minimization is considered a main objective of transit agencies. This trade-off between quality and cost turns transit network design into a multiobjective problem in which the interests of passengers and operators conflict. Transit network design involves the determination of various design elements, such as route alignments and stop locations, which are essential to serve transit demand within a particular area. The design of a transit network typically starts with the generation of a set of potential routes through the use of a candidate route generation algorithm. Existing route generation algorithms find the shortest path between a route’s origin and destination. Demand is aggregated without proper attention given to its pattern and distribution along the generated route. Given that demand actually is scattered along the transit route, the aggregate demand assumption is considered a major drawback of existing route generation algorithms. In an attempt to fill the highlighted gap in current practice, this paper presents a novel demand-sensitive candidate route generation algorithm that can address passenger and operator needs in a simple, objective function that aims to maximize route-level ridership. The proposed approach is well suited to small and rural communities and specialized transit services (e.g., flex route, demand responsive service) in which transit demand is dispersed.

Published: July 2016

This paper presents the results of a survey conducted to measure the service quality of the high-speed railway system (HSRS) that operates between two cities in Turkey. The analysis had its basis in the impact score technique. The survey was prepared to ask users for satisfaction ratings of 61 attributes, which were constructed for the seven dimensions of service quality for public transportation systems: passenger information, fare level and type, accessibility, station environment, vehicle environment, service delivery, and security. Through analysis of the results, the most problematic areas of the service provided by the HSRS were determined. According to the model results, the operator of the system should provide enhancements especially in the seat design of the vehicles and also regarding the time and the frequency of the service provided.
Designing a Framework to Improve Time Series Data of Construction Projects: Application of a Simulation Model and Singular Spectrum Analysis
Authors: Hojjati Tavassoli Zahra , Iranmanesh Seyed , Tavassoli Hojjati Ahmad
Published: July 2016

During a construction project life cycle, project costs and time estimations contribute greatly to baseline scheduling. Besides, schedule risk analysis and project control are also influenced by the above factors. Although many papers have offered estimation techniques, little attempt has been made to generate project time series data as daily progressive estimations in different project environments that could help researchers in generating general and customized formulae in further studies. This paper, however, is an attempt to introduce a new simulation approach to reflect the data regarding time series progress of the project, considering the specifications and the complexity of the project and the environment where the project is performed. Moreover, this simulator can equip project managers with estimated information, which reassures them of the execution stages of the project although they lack historical data. A case study is presented to show the usefulness of the model and its applicability in practice. In this study, singular spectrum analysis has been employed to analyze the simulated outputs, and the results are separated based on their signal and noise trends. The signal trend is used as a point-of-reference to compare the outputs of a simulation employing S-curve technique results and the formulae corresponding to earned value management, as well as the life of a given project.
Adsorption, Desorption, Surface Diffusion, Lattice Defect Formation, and Kink Incorporation Processes of Particles on Growth Interfaces of Colloidal Crystals with Attractive Interactions
Authors: Suzuki Yoshihisa , Hattori Yoshiaki , Nozawa Jun , Uda Satoshi , Toyotama Akiko , Yamanaka Junpei
Published: July 2016

Good model systems are required in order to understand crystal growth processes because, in many cases, precise incorporation processes of atoms or molecules cannot be visualized easily at the atomic or molecular level. Using a transmission-type optical microscope, we have successfully observed in situ adsorption, desorption, surface diffusion, lattice defect formation, and kink incorporation of particles on growth interfaces of colloidal crystals of polystyrene particles in aqueous sodium polyacrylate solutions. Precise surface transportation and kink incorporation processes of the particles into the colloidal crystals with attractive interactions were observed in situ at the particle level. In particular, contrary to the conventional expectations, the diffusion of particles along steps around a two-dimensional island of the growth interface was not the main route for kink incorporation. This is probably due to the number of bonds between adsorbed particles and particles in a crystal; the number exceeds the limit at which a particle easily exchanges its position to the adjacent one along the step. We also found novel desorption processes of particles from steps to terraces, attributing them to the assistance of attractive forces from additionally adsorbing particles to the particles on the steps.
A Novel Strategy for Optimising Decentralised Energy Exchange for Prosumers
Authors: Sha Ang , Aiello Marco
Published: July 2016

The realization of the Smart Grid vision will change the way of producing and distributing electrical energy. It paves the road for end-users to become pro-active in the distribution system and, equipped with renewable energy generators such as a photovoltaic panel, to become a so called “prosumer”. The prosumer is engaged in both energy production and consumption. Prosumers’ energy can be transmitted and exchanged as a commodity between end-users, disrupting the traditional utility model. The appeal of such scenario lies in the engagement of the end user, in facilitating the introduction and optimization of renewables, and in engaging the end-user in its energy management. To facilitate the transition to a prosumers’ governed grid, we propose a novel strategy for optimizing decentralized energy exchange in digitalized power grids, i.e., the Smart Grid. The strategy considers prosumer’s involvement, energy loss of delivery, network topology, and physical constraints of distribution networks. To evaluate the solution, we build a simulation program and design three meaningful evaluation cases according to different energy flow patterns. The simulation results indicate that, compared to traditional power distribution system, the maximum reduction of energy loss, energy costs, energy provided by the electric utility based using the proposed strategy can reach 51 % , 66 % , 97.5 % , depending on the strategy. Moreover, the proportion of energy self-satisfaction approaches reaches 98 % .
Spatial Inequalities and Wind Farm Development in the Dodecanese Islands—Legislative Framework and Planning: A Review
Authors: Panagiotidou Maria , Xydis George , Koroneos Christopher
Published: July 2016

Islands present sustainable energy growth challenges due to a number of reasons such as remoteness, limited energy resources, vulnerability to external events and strong dependence on international trade agreements. In particular, the Dodecanese Islands of the Aegean Sea cover their electricity needs mostly on the basis of autonomous conventional stations, consuming significant quantities of imported oil annually. Renewable energy sources (RES) penetration increase addresses the global requirements towards a carbon neutral environment, and wind farms (WFs) are among the most well-known green electricity-production alternatives. The study explores wind power installation potential of the Dodecanese Islands and the storage or interconnection options, based on the national and European legislative framework and the international scientific literature. The major finding is that, due to the high wind potential of the area, the National policy and targets focus on the installation of great RES power at Greek islands. Hence, private interests, who are willing to carry out the electrical interconnection of islands to the mainland, serve the same objective. Both scientific and business proposals overcome the local wind power installation capacity and neglect local specifics and needs.
Cancer-Specific Telomerase Reverse Transcriptase (TERT) Promoter Mutations: Biological and Clinical Implications
Authors: Liu Tiantian , Yuan Xiaotian , Xu Dawei
Published: July 2016

The accumulated evidence has pointed to a key role of telomerase in carcinogenesis. As a RNA-dependent DNA polymerase, telomerase synthesizes telomeric DNA at the end of linear chromosomes, and attenuates or prevents telomere erosion associated with cell divisions. By lengthening telomeres, telomerase extends cellular life-span or even induces immortalization. Consistent with its functional activity, telomerase is silent in most human normal somatic cells while active only in germ-line, stem and other highly proliferative cells. In contrast, telomerase activation widely occurs in human cancer and the enzymatic activity is detectable in up to 90% of malignancies. Recently, hotspot point mutations in the regulatory region of the telomerase reverse transcriptase (TERT) gene, encoding the core catalytic component of telomerase, was identified as a novel mechanism to activate telomerase in cancer. This review discusses the cancer-specific TERT promoter mutations and potential biological and clinical significances.

Published: July 2016

Background: To examine whether stress management mediates the relationship between purpose in life and self-rated health status (SRH). Methods: A cross-sectional survey was conducted among 6840 teachers in 2013 in Guangzhou, China. Purpose in life was assessed through the Purpose in Life Subscale of the Psychological Well-being Scale. Stress management was assessed using the eight-item questionnaire adapted from the Health-promoting Lifestyle Profile II. SRH was assessed by the Suboptimal Health Measurement Scale Version 1.0. The mediation hypothesis was tested by the structural equation model for path analysis. Results: It was found that purpose in life had direct and indirect effects on SRH. The path analysis showed the total effect (β = 0.563) of purpose in life on SRH was comprised of a direct effect (β = 0.319) and an indirect effect (β = 0.244), which was mediated by stress management. Conclusions: By supporting the mediation hypothesis, our results indicate that stress management mediated the effect of purpose in life on SRH. Enhancement of teachers’ purpose in life and improvement of training skills of stress management should be incorporated in the strategy of improving teachers’ health.

Published: July 2016

Interference of the binding of programmed cell death protein 1 (PD-1) and programmed death-ligand 1 (PD-L1) has become a new inspiring immunotherapy for resisting cancers. To date, the FDA has approved two PD-1 monoclonal antibody drugs against cancer as well as a monoclonal antibody for PD-L1. More PD-1 and PD-L1 monoclonal antibody drugs are on their way in clinical trials. In this review, we focused on the mechanism of the PD-1/PD-L1 signaling pathway and the monoclonal antibodies (mAbs) against PD-1 and PD-L1, which were approved by the FDA or are still in clinical trials. And also presented is the prospect of the PD-1/PD-L1 immune checkpoint blockade in the next generation of immunotherapy.
Introduction to the Special Issue on Evaluating the Security of Complex Systems
Authors: Fernandez Eduardo
Published: July 2016

Recent security breaches show the need to secure large, distributed, complex systems. A fundamental, but little discussed aspect of security is how to evaluate when a complete system is secure. Purely formal methods cannot handle this level of complexity. Code checking does not consider the interaction of separate modules working together and is hard to scale. Model-based approaches, such as patterns and problem frames, can be effective for handling large systems. Their use in evaluating security appears promising. A few works in this direction exist, but there is a need for more ideas. This Special Issue focuses on global, model-based, architectural, and systems-oriented evaluation methods.
Social Media Systems in the Workplace: Toward Understanding Employee Knowledge Creation via Microblogging within Shared Knowledge Domains
Authors: Cleveland Simon
Published: July 2016

Adoption of social media systems (SMS), proprietary microblogging platforms in particular, for the purposes of information sharing has been increasingly on the rise among corporations. While Twitter is the preferred microblogging tool by the general public, there is scant research to address its viability as a conduit to facilitate knowledge creation among corporate users. As a result, this conceptual paper explores seven crucial Twitter features and derives to seven propositions that demonstrate how microblogging can enable knowledge creation among employees within shared knowledge domain.
Adsorption of Heavy Metals by Graphene Oxide/Cellulose Hydrogel Prepared from NaOH/Urea Aqueous Solution
Authors: Chen Xiong , Zhou Sukun , Zhang Liming , You Tingting , Xu Feng
Published: July 2016

By taking advantage of cellulose, graphene oxide (GO), and the process for crosslinking using epichlorohydrin (ECH), we propose a simple and novel method to prepare GO/cellulose hydrogel with good potential to adsorb metal ions. GO nanosheets containing carboxyl and hydroxyl groups were introduced into the surface of the cellulose hydrogel with retention of the gel structure and its nanoporous property. Due to the introduction of GO, the GO/cellulose composite hydrogels exhibited good compressive strength. Adsorption capacity of Cu2+ significantly increases with an increase in the GO/cellulose ratio and GO/cellulose hydrogel showed high adsorption rates. The calculated adsorption capacities at equilibrium ( q e cal ) for GO/cellulose hydrogel (GO:cellulose = 20:100 in weight) was up to 94.34 mg·g−1, which was much higher than that of the pristine cellulose hydrogels. Furthermore, GO/cellulose hydrogel exhibited high efficient regeneration and metal ion recovery, and high adsorption capacity for Zn2+, Fe3+, and Pb2+.
Uncertainty Relations for Quantum Coherence
Authors: Singh Uttam , Pati Arun , Bera Manabendra
Published: July 2016

Coherence of a quantum state intrinsically depends on the choice of the reference basis. A natural question to ask is the following: if we use two or more incompatible reference bases, can there be some trade-off relation between the coherence measures in different reference bases? We show that the quantum coherence of a state as quantified by the relative entropy of coherence in two or more noncommuting reference bases respects uncertainty like relations for a given state of single and bipartite quantum systems. In the case of bipartite systems, we find that the presence of entanglement may tighten the above relation. Further, we find an upper bound on the sum of the relative entropies of coherence of bipartite quantum states in two noncommuting reference bases. Moreover, we provide an upper bound on the absolute value of the difference of the relative entropies of coherence calculated with respect to two incompatible bases.
What Motivates Authors of Scholarly Articles? The Importance of Journal Attributes and Potential Audience on Publication Choice
Authors: Tenopir Carol , Dalton Elizabeth , Fish Allison , Christian Lisa , Jones Misty , Smith MacKenzie
Published: July 2016

In this article we examine what motivations influence academic authors in selecting a journal in which to publish. A survey was sent to approximately 15,000 faculty, graduate students, and postdoctoral researchers at four large North American research universities with a response rate of 14.4% (n = 2021). Respondents were asked to rate how eight different journal attributes and five different audiences influence their choice of publication output. Within the sample, the most highly rated attributes are quality and reputation of journal and fit with the scope of the journal; open access is the least important attribute. Researchers at other research-intensive institutions are considered the most important audience, while the general public is the least important. There are significant differences across subject disciplines and position types. Our findings have implications for understanding the adoption of open access publishing models.

A Likelihood-Based SLIC Superpixel Algorithm for SAR Images Using Generalized Gamma Distribution
Authors: Zou Huanxin , Qin Xianxiang , Zhou Shilin , Ji Kefeng
Published: July 2016

The simple linear iterative clustering (SLIC) method is a recently proposed popular superpixel algorithm. However, this method may generate bad superpixels for synthetic aperture radar (SAR) images due to effects of speckle and the large dynamic range of pixel intensity. In this paper, an improved SLIC algorithm for SAR images is proposed. This algorithm exploits the likelihood information of SAR image pixel clusters. Specifically, a local clustering scheme combining intensity similarity with spatial proximity is proposed. Additionally, for post-processing, a local edge-evolving scheme that combines spatial context and likelihood information is introduced as an alternative to the connected components algorithm. To estimate the likelihood information of SAR image clusters, we incorporated a generalized gamma distribution (GГD). Finally, the superiority of the proposed algorithm was validated using both simulated and real-world SAR images.
Exploring Spatial-Temporal Patterns of Urban Human Mobility Hotspots
Authors: Yang Xiping , Zhao Zhiyuan , Lu Shiwei
Published: July 2016

Understanding human mobility patterns provides us with knowledge about human mobility in an urban context, which plays a critical role in urban planning, traffic management and the spread of disease. Recently, the availability of large-scale human-sensing datasets enables us to analyze human mobility patterns and the relationships between humans and their living environments on an unprecedented spatial and temporal scale to improve decision-making regarding the quality of life of citizens. This study aims to characterize the urban spatial-temporal dynamic from the perspective of human mobility hotspots by using mobile phone location data. We propose a workflow to identify human convergent and dispersive hotspots that represent the status of human mobility in local areas and group these hotspots into different classes according to clustering their temporal signatures. To illustrate our proposed approach, a case study of Shenzhen, China, has been conducted. Six typical spatial-temporal patterns in the city are identified and discussed by combining the spatial distribution of these identified patterns with urban functional areas. The findings enable us to understand the human dynamics in a different area of the city, which can serve as a reference for urban planning and traffic management.
Conjoint Analysis of Farmers’ Response to Conservation Incentives
Authors: Conner David , Miller Jennifer , Zia Asim , Wang Qingbin , Darby Heather
Published: July 2016

Environmental degradation threatens the long term resiliency of the US food and farming system. While USDA has provided conservation incentives for the adoption of best management practices (BMPs), only a small percentage of farms have participated in such conservation programs. This study uses conjoint analysis to examine Vermont farmers’ underlying preferences and willingness-to-accept (WTA) incentives for three common BMPs. Based on the results of this survey, we hypothesize that federal cost share programs’ payments are below preferred incentive levels and that less familiar and more complex BMPs require a higher payment. Our implications focus on strategies to test these hypotheses and align incentive payments and other non-monetary options to increase BMP adoption.
A Patent Analysis for Sustainable Technology Management
Authors: Choi Junhyeog , Jun Sunghae , Park Sangsung
Published: July 2016

Technology analysis (TA) is an important issue in the management of technology. Most R&D (Research & Development) policies have depended on diverse TA results. Traditional TA results have been obtained through qualitative approaches such as the Delphi expert survey, scenario analysis, or technology road mapping. Although they are representative methods for TA, they are not stable because their results are dependent on the experts’ knowledge and subjective experience. To solve this problem, recently many studies on TA have been focused on quantitative approaches, such as patent analysis. A patent document has diverse information of developed technologies, and thus, patent is one form of objective data for TA. In addition, sustainable technology has been a big issue in the TA fields, because most companies have their technological competitiveness through the sustainable technology. Sustainable technology is a technology keeping the technological superiority of a company. So a country as well as a company should consider sustainable technology for technological competition and continuous economic growth. Also it is important to manage sustainable technology in a given technology domain. In this paper, we propose a new patent analysis approach based on statistical analysis for the management of sustainable technology (MOST). Our proposed methodology for the MOST is to extract a technological structure and relationship for knowing the sustainable technology. To do this, we develop a hierarchical diagram of technology for finding the causal relationships among technological keywords of a given domain. The aim of the paper is to select the sustainable technology and to create the hierarchical technology paths to sustainable technology for the MOST. This contributes to planning R&D strategy for the sustainability of a company. To show how the methodology can be applied to real problem, we perform a case study using retrieved patent documents related to telematics technology.
Comparative Anatomy of the Trabecular Meshwork, the Optic Nerve Head and the Inner Retina in Rodent and Primate Models Used for Glaucoma Research

Published: July 2016

Glaucoma is a heterogeneous group of ocular disorders with a multi-faceted etiology. Although numerous studies on glaucoma using different animal models have been published, it is unwise to simply generalize the results of one model to all glaucomatous situations because of the differences in the anatomy and morphology of animal eyes in comparison with humans’. In this review, we highlight the differences in the trabecular meshwork (TM) tissue, lamina cribrosa (LC) region, optic nerve head (ONH) and the inner layer of the retina in mice, rats and monkeys. In comparison with humans, non-human primates show TM, retina and ONH that are anatomically almost identical. The rat model shows many similarities in the aqueous outflow pathway compared to humans. The mouse ONH lacks collagenous LC, and this finding is observed across different mouse strains. The tissue structure of the ONH in rodents is similar to that in humans, although the blood supply shows differences. The number of cells in the ganglion layer depends on the rodent strain. Despite some differences from humans, rodents are a good choice for studying different types of glaucoma, and the modeling method should be selected based on the experimental needs and the hypothesis being tested.

The paper presents a study leading to a new acute toxicity test on embryonic and juvenile organisms of the great pond snail (Lymnaea stagnalis Linnaeus). Sulfuric acid, nitric acid, and ammonium hydroxide were used as waterborne toxicants in laboratory experiments. The exposure time was 24 h. Tests were conducted in 5–10 replications for each toxicant. The toxicity of the substances was classified according to different scales and the test’s sensitivity was compared to that of the commonly used bioindicator Daphnia magna Straus. The assessment of toxicity impact was supported by microscopic observations. The probit method was used as a parametric statistical procedure to estimate LC50 and the associated 95% confidence interval. Our study showed that the early developmental stages of Lymnaea stagnalis are very sensitive bioindicators, making it possible to detect even very low levels of the above-mentioned water toxicants. The highest toxicity is shown by ammonium hydroxide with LC50/24h values, respectively, 24.27 for embryos and 24.72 for juvenile forms, and the lowest is shown by nitric acid ions with LC50/24h values, respectively, 105.19 for embryos and 170.47 for juvenile forms. It is highly cost-effective due to simple and efficient breeding and the small size of the organisms in the bioassay population. Compared with Daphnia magna, relatively low concentrations of toxicants caused a lethal effect on embryonic and juvenile organisms of the great pond snail. Owing to their common occurrence and sensitivity, early developmental forms of Lymnaea stagnalis can be a valuable new tool in biomonitoring of the freshwater environment.
Deciphering the evolutionary interplay between subgenomes following polyploidy: A paleogenomics approach in grasses
Authors: Salse Jérôme
Published: July 2016

How did plant species emerge from their most recent common ancestors (MRCAs) 250 million years ago? Modern plant genomes help to address such key questions in unveiling precise species genealogies. The field of paleogenomics is undergoing a paradigm shift for investigating species evolution from the study of ancestral genomes from extinct species to deciphering the evolutionary forces (in terms of duplication, fusion, fission, deletion, and translocation) that drove present‐day plant diversity (in terms of chromosome/gene number and genome size). In this review, inferred ancestral karyotype genomes are shown to be powerful tools to (1) unravel the past history of extant species by recovering the variations of ancestral genomic compartments and (2) accelerate translational research by facilitating the transfer of genomic information from model systems to species of agronomic interest.

We present results from the the first campaign of dedicated solar observations undertaken by the Nuclear Spectroscopic Telescope ARray (NuSTAR) hard X-ray (HXR) telescope. Designed as an astrophysics mission, NuSTAR nonetheless has the capability of directly imaging the Sun at HXR energies (>3 keV) with an increase in sensitivity of at least two magnitude compared to current non-focusing telescopes. In this paper we describe the scientific areas where NuSTAR will make major improvements on existing solar measurements. We report on the techniques used to observe the Sun with NuSTAR, their limitations and complications, and the procedures developed to optimize solar data quality derived from our experience with the initial solar observations. These first observations are briefly described, including the measurement of the Fe K-shell lines in a decaying X-class flare, HXR emission from high in the solar corona, and full-disk HXR images of the Sun.
WATER MASERS IN THE ANDROMEDA GALAXY. I. A SURVEY FOR WATER MASERS, AMMONIA, AND HYDROGEN RECOMBINATION LINES
Authors: Darling Jeremy , Gerard Benjamin , Amiri Nikta , Lawrence Kelsey
Published: July 2016

We report the results of a Green Bank Telescope survey for water masers, ammonia (1, 1) and (2, 2), and the H66α recombination line toward 506 luminous compact 24 μm emitting regions in the Andromeda Galaxy (M31). We include the 206 sources observed in the Darling water maser survey for completeness. The survey was sensitive enough to detect any maser useful for ∼10 μas yr−1 astrometry. No new water masers, ammonia lines, or H66α recombination lines were detected individually or in spectral stacks reaching rms noise levels of ∼3 mJy and ∼0.2 mJy, respectively, in 3.1–3.3 km s−1 channels. The lack of detections in individual spectra and in the spectral stacks is consistent with Galactic extrapolations. Contrary to previous assertions, there do not seem to be any additional bright water masers to be found in M31. The strong variability of water masers may enable new maser detections in the future, but variability may also limit the astrometric utility of known (or future) masers because flaring masers must also fade.

We report on a common fragment ion formed during the electron-ionization-induced fragmentation of three different three-ring polycyclic aromatic hydrocarbons (PAHs), fluorene (C13H10), 9,10-dihydrophenanthrene (C14H12), and 9,10-dihydroanthracene (C14H12). The infrared spectra of the mass-isolated product ions with m/z = 165 were obtained in a Fourier transform ion cyclotron resonance mass spectrometer whose cell was placed inside the optical cavity of an infrared free-electron laser, thus providing the high photon fluence required for efficient infrared multiple-photon dissociation. The infrared spectra of the m/z = 165 species generated from the three different precursors were found to be similar, suggesting the formation of a single

isomer. Theoretical calculations using density functional theory (DFT) revealed the fragment's identity as the closed-shell fluorenyl cation. Decomposition pathways from each parent precursor to the fluorenyl ion are proposed on the basis of DFT calculations. The identification of a single fragmentation product from three different PAHs supports the notion of the existence of common decomposition pathways of PAHs in general and can aid in understanding the fragmentation chemistry of astronomical PAH species.

Published: July 2016

We present a detailed analysis of the properties of magnetic reconnection at large-scale current sheets (CSs) in a high cadence version of the Lynch & Edmondson 2.5D MHD simulation of sympathetic magnetic breakout eruptions from a pseudostreamer source region. We examine the resistive tearing and break-up of the three main CSs into chains of X- and O-type null points and follow the dynamics of magnetic island growth, their merging, transit, and ejection with the reconnection exhaust. For each CS, we quantify the evolution of the length-to-width aspect ratio (up to ∼100:1), Lundquist number (∼103), and reconnection rate (inflow-to-outflow ratios reaching ∼0.40). We examine the statistical and spectral properties of the fluctuations in the CSs resulting from the plasmoid instability, including the distribution of magnetic island area, mass, and flux content. We show that the temporal evolution of the spectral index of the reconnection-generated magnetic energy density fluctuations appear to reflect global properties of the CS evolution. Our results are in excellent agreement with recent, high-resolution reconnection-in-a-box simulations even though our CSs’ formation, growth, and dynamics are intrinsically coupled to the global evolution of sequential sympathetic coronal mass ejection eruptions.
