Nature-Inspired Design of Smart Biomaterials Using the Chemical Biology of Nucleic Acids
Authors: Pandian Ganesh N , Sugiyama Hiroshi 
Published: August 2016

Abstract
In the natural cellular environment, nucleic acid biomolecules like DNA have biological implications via structural modifications and through precise coordination with other biomolecules in the local environment. Here, we detail the design of nature-inspired smart biomaterials that are based on the chemical biology of nucleic acids. N-Methylpyrrole (P) and N-methylimidazole (I) polyamides (PIPs), sequence-specific DNA-binding molecules have been, developed to image specific DNA sequences and to alter gene expression inside the living cells. The self-assembling feature of DNA was harnessed to achieve the programmed assembly of nanostructures with different dimensions. Also, the advanced DNA architectures with well-defined properties allowed the real-time visualization of the complicated single-molecule interactions, which in-turn provided vital intracellular mechanistic information. The molecular recognition properties of DNA were exploited to design biologically inspired hybrid catalysts for sustainable organic synthesis. Our review could serve as a guidebook for researchers who aim to develop nucleic acid-based synthetic biomaterials.
Portfolio Choice Based on Third-Degree Stochastic Dominance
Authors: Post Thierry , Kopa Miloš 
Published: August 2016

We develop an optimization method for constructing investment portfolios that dominate a given benchmark portfolio in terms of third-degree stochastic dominance. Our approach relies on the properties of the semivariance function, a refinement of an existing “superconvex” dominance condition, and quadratic constrained programming. We apply our method to historical stock market data using an industry momentum strategy. Our enhanced portfolio generates important performance improvements compared with alternatives based on mean-variance dominance and second-degree stochastic dominance. Relative to the Center for Research in Security Prices all-share index, our portfolio increases average out-of-sample return by almost seven percentage points per annum without incurring more downside risk, using quarterly rebalancing and without short selling.

SPECTATEUR ET LIEN COMMUN: INVENTION ET TRANSFORMATIONS
Authors: Lontrade Agnès 
Published: August 2016

L’invention du spectateur et du sujet esthétique au XVIIIe siècle a eu à la fois pour condition et pour conséquence l’ancrage du sentiment dans la communauté universelle. La naissance de l’espace public, en partie fruit de la circulation et de la confrontation des jugements dans la sphère de l’exposition et des discours s’y rattachant, est à la source de théories contemporaines de la critique d’art fondant, dans la lignée des travaux de Jürgen Habermas, l’évaluation esthétique sur l’intercompréhension et l’intersubjectivité des réceptions. Cet article s’attache à réfléchir les présupposés et les implications politiques de la critique d’art et de l’expérience esthétique ; réflexion qui nécessite de discuter les concepts, aujourd’hui ambivalents, de spectateur, de sens commun, de communication et de publicité.
A EDUCAÇÃO MATEMÁTICA E O PODER: UMA HISTÓRIA A CONTRAPELO
Authors: Artioli Rolim Carmem Lucia 
Published: August 2016

O presente artigo é resultado de uma pesquisa teórica, que busca compreender a educação matemática como processo sociocultural construído na historicidade dos sujeitos. Tendo por base a abordagem qualitativa, os procedimentos utilizados para o estudo compreendem a pesquisa bibliográfica e documental, com o objetivo de adentrar os mecanismos de poder, presentes na matemática, como processo educacional institucionalizado. Nesse contexto, são exploradas construções históricas da matemática escolar, considerando-se os instrumentos que classificam e adjetivam os sujeitos pautados pelo domínio do conhecimento matemático e legitimados pela classe hegemônica. Os resultados indicam que a educação matemática institucionalizada nas escolas não se desvincula da sociedade, pelo contrário, a ela responde, reafirmando a necessidade de questionar ideologias e analisar o papel da educação matemática como construção social, considerando-se os efeitos de controle e poder que perpassam os processos educacionais.

Published: August 2016

AbstractBackground:We provide a clinical and analytical evaluation of the reformulated version of the Abbott Architect 25-hydroxyvitamin D assay. We compared this assay with three commercial automated immunoassays and against a VDSP-traceable liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS) in six different populations. We also supplemented 40 healthy volunteers with either 600,000 IU of vitamin D2 or 100,000 of vitamin D3 to evaluate the performance of the immunoassays vs. the LC-MS/MS.Methods:Precision and limit of quantification were assessed, 25(OH)D2 and C3-epimer recovery were calculated. Two hundred and forty samples obtained in healthy Caucasians and Africans, osteoporotic, hemodialyzed and intensive care patients and 3rd trimester pregnant women were analyzed by all methods. Correlation was studied using Passing-Bablok and Bland-Altman analysis. Concordance correlation coefficient (CCC) was calculated to evaluate agreement between immunoassays and LC-MS/MS. We verified if patients were homogeneously classified with the immunoassays when they took vitamin D2 or vitamin D3 after 1, 7 and 28 days.Results:We observed excellent analytical features and showed a very good correlation to the LC-MS/MS results in the overall population. Compared to the other immunoassays, concordance of the new Abbott assay with the LC-MS/MS was at least similar, and often better in diseased populations. Althought the cross-reactivity with 25(OH)D2 was not of 100%, there was no significant difference in the classifications of the patients, either supplemented with D2 or D3 or after 7 or 28 days.Conclusions:This modified version of the Abbott Architect assay is clearly improved compared to the previous one and presents a better agreement with the LC-MS/MS.

Published: August 2016

Abstract
Microbial fuel cells (MFC’s) are promising energy harvesters to constantly supply energy to sensors deployed in aquatic environments where solar, thermal and vibration sources are inadequate. In order to show the ready-to-use MFC potential as energy scavengers, this paper presents the association of a durable benthic MFC with a few dollars of commercially-available power management units (PMU’s) dedicated to other kinds of harvesters. With 20 cm2 of cheap material electrodes, and experimental conditions similar to real ones, 101 µW has been generated at 320 mV in steady-state operation. In burst mode, the MFC can generate up to 400 µW. The PMU, configured to extract the maximum available energy, provides 47 µW at 3 V in steady state, which would allow a wide range of environmental sensors to be powered. A sensor node, consuming 100 µJ every 4 s for measurement and wireless transmission of temperature, has been successfully powered by the association of our MFC and the PMU.
A Minimized MIMO-UWB Antenna with High Isolation and Triple Band-Notched Functions
Authors: Kong Yuanyuan , Li Yingsong , Yu Kai 
Published: August 2016

AbstractA compact high isolation MIMO-UWB antenna with triple frequency rejection bands is proposed for UWB communication applications. The proposed MIMO-UWB antenna consists of two identical UWB antennas and each antenna element has a semicircle ring shaped radiation patch fed by a bend microstrip feeding line for covering the UWB band, which operates from 2.85 GHz to 11.79 GHz with an impedance bandwidth of 122.1 %. By etching a L-shaped slot on the ground plane, and embedding an “anchor” shaped stub into the patch and integrating an open ring under the semicircle shaped radiation patch, three notch bands are realized to suppress WiMAX (3.3–3.6 GHz), WLAN(5.725–5.825 GHz) and uplink of X-band satellite (7.9–8.4 GHz) signals. The high isolation with S21<–20 dB in most UWB band is obtained by adding a protruded decoupling structure. The design procedure of the MIMO-UWB antenna is given in detail. The proposed MIMO-UWB antenna is simulated, fabricated and measured. Experimental results demonstrate that the proposed MIMO-UWB antenna has a stable gain, good impedance match, high isolation, low envelope correlation coefficient and good radiation pattern at the UWB operating band and it can provide three designated notch bands.

Abstract
In this work, a methodology to measure torque during dough mixing in large scale was developed and the baking performance of bread dough formulated with resistant starch (RS) and enzymes was evaluated. Dough was formulated with 12.5 g/100 g of RS and 4 mg/100 g of a mixture of enzymes, glucose-oxidase (Gox), tranglutaminase (TG) and xylanase (HE) in proportions according to a three-component mixture design of experiments. Dough was mixed in a large-scale dynamic rheometer measuring instant torque and speed in real time through a personal computer (PC) interface. Maximum torque during mixing and parameters of the dough development curves obtained from rheofermentometer were fit to mathematical models within 95 % of confidence. Gox and TG showed positive effects on the maximum height of dough, while HE showed a negative one. Also, it was found that Gox and TG in the presence of HE could be important for reducing dough weakening.
Care support points of Mecklenburg-West Pomerania. Results of a scientific analysis / Pflegestützpunkte in Mecklenburg-Vorpommern. Ergebnisse einer wissenschaftliche Analyse

Published: August 2016

AbstractBackgroundIn the period 2011 – 2013, 13 care support points were set up in Mecklenburg-West Pomerania. They are the joint responsibility of all health and long-term care insurance funds and local government.MethodBetween July and November 2013, data on organisation and personnel were collected in respect of the care support points and their advisory staff. Questions were asked about reasons for visiting a care support point, the subject matter of any counselling and demographic data on the users. Data were collected using questionnaires and interviews. Descriptive statistics were used to analyse quantitative data, the interviews were evaluated by analysis of their content.ResultsThe results show a heterogenic picture of adviser training. Most users made contact with the care support points by telephone. General information on long-term care insurance was frequently sought. In 2015, care support points were consulted much more frequently than in 2014. The partners describe the networking involved as time-consuming; any synergy effects to date were estimated to be limited.ConclusionsMore network structures need to be created if those in need of care and assistance as supplied by care counselling based on case management are to be reached in future. What is called for are firm, written contracts with no personal bias, assigning care support points with the role of central actors at the regional level, able to produce neutral, independent organization and coordination of the necessary assistance. A guarantee of continuity of provision would fulfill the requirements of the kind of procedure involved in case management. Regardless of the number of professional providers and informal carers participating.
Compounding errors: why heightened regulation and taxation are bad antidotes for recessions and income inequality
Authors: Epstein Richard A 
Published: August 2016

AbstractThe current concerns with laggard growth and income inequality have led to a widespread set of demands for more regulation and higher taxation to reverse the trend. These two approaches move matters exactly in the wrong direction. The correct response is to find ways to reduce tax burdens and barriers to entry, and to reduce the political uncertainty associated with new government measures. It may well be too late, worldwide, for a substantial rollback in the welfare state. But the current proposals will only prolong the dismal results on both fronts in any arena in which they are tried.

O objetivo desse estudo foi comparar as curvas de sensibilidade ao contraste de adultos e idosos. Foi medida a FSC para grades senoidais verticais utilizando o método psicofísico da escolha forçada (2AFC). Participaram desse estudo 18 adultos com idade entre 20 e 29 anos e 18 idosos com idade entre 60 a 69 anos, de ambos os sexos. A ANOVA mostrou efeito principal entre os grupos [F(1, 156) = 173,160; p < 0,001] e de interação entre as frequências espaciais e a idade [F(3,427) = 163,365; p < 0,001]. Já o teste Bonferroni mostrou diferenças significantes em todas as frequências testadas (p < 0,001). Verificou-se que o padrão da curva de SC se mantém com o envelhecimento, com a menor sensibilidade localizada nos extremos da curva e a maior sensibilidade localizada próxima ao centro da curva. Além disso, sugere-se alterações no processo senso perceptivo visual ao longo da vida.

Published: August 2016

O objetivo deste estudo foi investigar o envolvimento paterno de 35 pais (18 a 40 anos), cujo filho tinha 12 meses de vida. Os pais responderam a uma entrevista e as suas respostas foram examinadas através de análise de conteúdo qualitativa, com base em três dimensões do envolvimento paterno: interação, disponibilidade e responsabilidade. Os pais relataram se envolver com o filho de acordo com as necessidades e habilidades específicas dos 12 meses, idade em que o bebê passa a ser mais responsivo. Contudo, alguns pais relataram não ter a habilidade necessária para cuidar de um bebê, o que pode contribuir para um menor envolvimento com o filho. Os resultados do estudo evidenciam que os pais mostraram-se competentes para lidar com um bebê com novas habilidades, mesmo que, em alguns momentos, eles parecessem sentir dificuldades ou ainda preferissem que a mãe realizasse determinadas atividades.

Authors: Xue Jianfeng , Shen Peihui , Wang Xiaoming 
Published: August 2016

To address the ricochet problem in penetration process, the mathematical model of projectile penetrating into concrete target is established according to the basic kinetic equation and surface layer mechanism. The motion trajectory of projectile nose is obtained. Experimental studies on projectiles with different nose penetrating into concrete targets are conducted to explain the ricochet problem. These studies analyze fifty-four penetration conditions under different initial velocities and oblique angles when the projectiles have flat, hemispherical, ogive noses and conical noses. The regularity and critical angles of ricochet are analyzed with different nose shapes at different velocities. Results show that the ricochet angle increases depending on nose sharp and penetration velocity. The factors affecting the ricochet from big to small were analyzed via orthogonal test. The results show that with increasing the velocity from 652 m/s to 1022 m/s, the critical angle increases from 44° to 66°. The order of factors affecting the ricochet from big to small is the shape of the nose, the material of the projectiles and the penetrating velocity respectively.
