Authors: Schlösser Adriano , Camargo Brigido Vizeu , Giacomozzi Andréia Isabel , Fiorott Juliana Gomes
Published: March 2020

O objetivo deste estudo foi investigar a saúde mental e psicopatologia associada entre indivíduos tatuados e não tatuados, de ambos os sexos. Participaram 614 indivíduos, divididos entre 306 com tatuagem e 308 sem tatuagem. Foi desenvolvido um questionário online autoadministrado, com respostas abertas e fechadas. O questionário apresentou 2 blocos de informações: a) questões sócio-demográficas: idade, estado civil, religião, escolaridade e quantidade de tatuagens; b) comportamento de risco: transtornos psicológicos e ideação suicida. Para análise de dados, foi realizada análise estatística descritiva e relacional, com auxílio do programa estatístico SPSS- versão 17.0. Os resultados indicaram associações estatisticamente significativas associadas a diagnóstico psiquiátrico entre mulheres tatuadas, e ideação suicida entre mulheres não tatuadas. Embora com resultados estatisticamente significativos, ressalta-se que os valores apresentados entre tatuados e não tatuados foram muito semelhantes, indicando-se cautela em associar comportamentos desviantes a indivíduos com tatuagens.

São diversas as variáveis que interferem no tratamento de doenças graves e crônicas, sendo uma delas a personalidade. Assim, o presente estudo teve como objetivo identificar os traços de personalidade relacionados com comportamento de adesão ao tratamento de saúde em grupos hemodíalitico e oncológico. Participaram da pesquisa 50 pacientes, sendo 68% mulheres, com média de idade de 53,64 anos (DP=15,37), em que 30 estavam em tratamento hemodilítico e 20 em tratamento oncológico. Foram aplicados um Questionário Socioeconômico, um Questionário de Autoavaliação da Adesão ao Tratamento de Saúde e os Marcadores Reduzidos para Avaliação da Personalidade. Nos resultados foi possível verificar que traços de personalidade como Socialização e Conscienciosidade se correlacionam positivamente ao comportamento de adesão em ambos os grupos. Com esses dados é possível verificar que considerar a personalidade de cada paciente é importante para auxiliá-lo no processo de enfrentamento e na adesão do tratamento fornecido.

Authors: Da Silva Jean Paulo , Becker da Silva Mariana Luíza , Barbará da Silva Bousfield Andréa
Published: March 2020

Um significativo número de óbitos ocorre devido à hipertensão arterial sistêmica (HAS). O tratamento pode possuir dificuldades de concretização devido às ideias sociais que circulam sobre a HAS. Esta pesquisa utilizou a Teoria das Representações Sociais, tendo em vista a possibilidade de conhecimento do saber social, que pode contribuir para as políticas públicas. Assim, objetivou-se identificar as representações sociais da HAS, do tratamento e do convívio com a doença para pessoas que vivem com essa condição clínica. Foram realizadas entrevistas semiestruturadas na residência de 60 usuários do Sistema Único de Saúde na cidade de Jaraguá do Sul – SC que convivem com a HAS há no mínimo dois anos. Os dados foram submetidos à três análises hierárquicas descendentes por meio do software IRaMuTeQ. Uma em relação à HAS, outra ao tratamento e outra sobre o convívio com a doença. Os resultados demonstraram que a representação social da hipertensão arterial, do tratamento e do convívio com a doença compartilham entre si significados centralizados no contexto prático. Este contexto é associado principalmente ao uso do medicamento, sendo pouco mencionado o controle não medicamentoso. Ressalta-se a necessidade de políticas públicas que considerem as representações sociais sobre o fenômeno.

Strategies to Prevent Online Sexual Abuse of Children
Authors: Ryckman Leah Fay , Guerra Cristóbal , Finch Anastasia
Published: March 2020

Online sexual abuse of children has severe and lasting implications. In addition to there being many avenues to commit sexual offences via technology, there are many ways to intervene. Industry-related prevention and intervention strategies are often targeted at blocking or catching a potential offender. Justice initiatives through punitive measures are targeted towards the perpetrator. Education and awareness campaigns are a means to prevent abuse before it happens or help a victim come forward to seek support and retribution. A systematic review of the literature will endeavour to find research that emphasizes intervention through education and awareness strategies for children and adolescents, including an analysis of the effectiveness of such programs. This protocol follows PRISMA guidelines for systematic reviews and provides details of the literature review and research parameters.
Towards a blockchain-based certificate authentication system in Vietnam
Authors: Nguyen Binh Minh , Dao Thanh-Chung , Do Ba-Lam
Published: March 2020

Anti-forgery information, transaction verification, and smart contract are functionalities of blockchain technology that can change the traditional business processes of IT applications. These functionalities increase the data transparency, and trust of users in the new application models, thus resolving many different social problems today. In this work, we take all the advantages of this technology to build a blockchain-based authentication system (called the Vietnamese Educational Certification blockchain, which stands for VECefblock) to deal with the delimitation of fake certificate issues in Vietnam. In this direction, firstly, we categorize and analyze blockchain research and application trends to make out our contributions in this domain. Our motivating factor is to curb fake certificates in Vietnam by applying the suitability of blockchain technology to the problem domain. This study proposed some blockchain-based application development principles in order to build a step by step VECefblock with the following procedures: designing overall architecture along with business processes, data mapping structure and implementing the decentralized application that can meet the specific Vietnamese requirements. To test system functionalities, we used Hyperledger Fabric as a blockchain platform that is deployed on the Amazon EC2 cloud. Through performance evaluations, we proved the operability of VECefblock in the practical deployment environment. This experiment also shows the feasibility of our proposal, thus promoting the application of blockchain technology to deal with social problems in general as well as certificate management in Vietnam.

Authors: Tomar Mandeep , Gautam Neha , Chauhan Anubhav , Gupta Lalit , Singh Surat
Published: March 2020

Ticks are ectoparasites which live by hematophagy and transmit zoonoses including Lyme disease, tularemia, Scrub typhus, etc. We present a short case series of 3 cases of tick infestations of the eyelids in a span of 3 weeks during the winter season in our centre. 2 patients were elderly females and in one case a young school boy was affected. Two patients had tick manifestation in upper eyelid and in 1 case lateral canthal skin was affected. Chief complaint of all patients was pain, redness and swelling of the eyelids from last 48-72 hours and no patient was aware of any live organism attached to their eyelids. Complete mechanical removal of ticks with blunt non toothed forceps under slit lamp was done and sent for microbiological examination, which revealed them to be hard ticks of genus Ixodes. All patients were given antibiotic prophylaxis. Neither patient developed systemic disease or adverse sequelae after tick extraction. Complete mechanical removal of ticks located on the eyelid with blunt forceps is a safe and effective treatment method.

Published: March 2020

A 25 year old male presented with pain, redness, sudden loss of vision in left eye with features of acute angle closure glaucoma. Ultrasound biomicroscopy showed a large single iris stromal cyst occupying the anterior chamber covering the pupil. ND:YAG laser iridotomy was done. Intraocular pressure became normal and vision improved to 6/9-. Iridocyclitis can occur in the natural course of the stromal cyst producing sudden enlargement of the cyst leading to pupillary block. To the best of our knowledge, no case has been published with large stromal cyst presenting as acute angle closure glaucoma secondary to pupillary block.
Bilateral Toxoplasma Retinochoroiditis with Franceschetti's Syndrome in an Immunocompetent Patient - An Unusual Presentation
Authors: Vallinayagam Muthukrishnan , Srikanth K. , Deepikadevi S. N. , Balla Shravya Choudhary
Published: March 2020

Toxoplasma gondii is a major cause of chronic ocular parasitic infection which leads to severe visual impairment. Toxoplasma retinochoroiditis is considered to be one of the most common causes of posterior uveitis and is usually unilateral in immunocompetent patients. Toxoplasmosis in immunocompromised patients may be bilateral with a fulminant course. Ocular toxoplasmosis can have protean manifestations, some of which may be atypical, posing diagnostic challenge. We report a case of ocular toxoplasmosis in a 24-year-old female with healthy immune system who presented with bilateral recurrent panuveitis. The fundus examination revealed bilateral active retinochoroiditis with traction band involving the disc and macula (Franceschetti's syndrome). The battery of investigations for granulomatous uveitis were normal. Serology showed evidence of toxoplasmosis and PCR of intraocular fluid confirmed the diagnosis. The patient was treated with anti toxoplasma medications and steroids. Atypical presentations of toxoplasmosis could be a diagnostic dilemma. Toxoplasmosis may present with simultaneous bilateral involvement in the absence of immunosuppressed status. Early diagnosis and prompt treatment could prevent vision threatening complications like traction bands, which portend a poor visual outcome. Toxoplasmosis should be considered in the differential diagnosis of bilateral pan uveitis in an immunocompetent patient and retinal traction bands could be an unusual manifestation of toxoplasma retinochoroiditis.

Published: March 2020

Bietti crystalline dystrophy (BCD) is a rare dystrophy that is characterized by numerous crystals in the peripapillary retina and the posterior pole. Imaging of the crystals has been done on various modalities like autofluorescence, infrared imaging, optical coherence tomography and adaptive optics. To the best of our knowledge, the multicolour (MC) imaging features of BCD have not been described. With our report we demonstrate that MC imaging provides valuable insights about the location of the crystals in the retinal layers.

Sowing Dates and Fertilizer Application on Growth and Yield of Muskmelon (Cucumis melo L.) at Ado-Ekiti
Authors: Aluko Matthew
Published: March 2020

Information on some agronomic practices are required for muskmelon production as there is no record of its production in Ado-Ekiti. A field study of 3 x 2 factorial experiment of sowing dates (January, May and September) and NPK 15:15:15 fertilizer application (0 and 333 kg ha-1) was laid out in a Randomized Complete Block Design in three replicates at the Teaching and Research Farm of Ekiti State University, Ado-Ekiti, Nigeria. Data collected on the number of leaves and branches, leaf area, vine length, day to flowering, 50% flowering, number of fruit, fruit size and yield were subjected to analysis of variance and treatment means separated by Duncan's Multiple Range Test at 5% probability. Dates of sowing did not significantly influence growth but muskmelon planted in May gave a higher number of leaves plant-1, leaf area and vine length. Fertilized plants produced better growth and earlier flowering than unfertilized plants. The number of fruits ha-1, average fruit weight and fruit yield ha-1 of 11606, 0.78 kg and 9.09 t ha-1 respectively were produced by fertilized plants which were significantly higher than 10036.70, 0.28 kg and 2.44 t ha-1 from unfertilized plants. Muskmelon planted in September produced a higher number of fruits and fruit yield of 12418 and 11.29 t ha-1 while muskmelon planted in May produced higher fruit weight (0.94 kg) but these did not differ significantly from other sowing dates. Planting muskmelon under the rain-fed condition with adequate fertilizer application gave better performance and is thereby recommended for muskmelon production in Ado-Ekiti.
Credit Management and Issues of Bad Debts: An Empirical Study of Listed Deposit Banks in Nigeria
Authors: Ayunku Peter E. , Uzochukwu Akwarandu
Published: March 2020

This study examines the impact of credit management on firm performance amidst bad debts, among Nigerian deposit banks. Five hypotheses were formulated following the dependent variables of Return on Asset and Tobin Q. The independent variables employed for this study include: Loan Loss Provision, Loan to Deposit Ratio, Equity to Asset Ratio, and Loan Write off. This study is based on ex-post facto research design and employed a panel data set collected from fourteen (14) commercial banks over six years ranging from 2014 to 2019 financial year. We analyzed the data set using descriptive statistics, correlation and Ordinary Least Square Regression Technique. The random effect models established that non-performing loan, loan loss provision and equity to asset impact significantly on banks’ performance in both Return on Asset and Tobin-Q models. This suggests that the sampled banks need to establish efficient arrangements to deal with credit risk management. In all, credit risk management indicators considered in this research are important variables in explaining the profitability of Nigerian commercial banks. However, based on the outcome from the empirical analysis, the study carefully recommends that investors and shareholders in these banks should be aware of the possible use of provisions for losses on non-performing loans by managers for smoothening of profits. The shareholders specifically should be ready to meet optimal agency costs to reduce the manager's information asymmetry by hiring competent internal and external auditors.

Aims: The aim of this study is to describe the age-related risk of overweight/obesity among Ghanaians using data from the WHO Study on global AGEing and adult health (SAGE) Wave 2.

Study Design: Cross sectional study.

Place and Duration of Study: Ghana; 2014-2015.

Methodology: Primary study variables were extracted onto Microsoft Excel 14.0 spreadsheet. Secondary variables were generated through grouping, recategorization and combination of primary variables. Descriptive statistics were calculated for age and BMI. Associations between respondents’ characteristics and BMI were evaluated with chi square(χ2) and odds ratio (OR) at 95% confidence level.

Results: Data of 1322 respondents were included in data analysis. In all, 520 (39.3%) of the respondents were overweight/obese and nearly half (46.62%) were middle-aged adults. Middle-aged adults were nearly twice as likely to be overweight/obese compared with old adults (AOR=1.62; CI: 1.25-2.10) and the risk was higher for middle-aged females (AOR=2.38; CI: 1.84-3.09). Overall, being middle-aged (OR=1.73; CI: 1.35-2.21); living in an urban community (OR=2.01; CI: 1.61-2.52); being a female (OR=2.69; CI: 2.1-3.44); not engaging in regular physical activity (OR=1.49; CI: 1.18-1.88); and being an occasional drinker of alcoholic beverage (OR=1.58; CI: 1,12-2.22) were significantly associated with overweight/obesity.

Conclusion: Obesity/overweight are lifestyle driven phenomenon and can be controlled by risk modification. Public sensitization, imposition of special taxes on sugary beverages, promotion of healthy local staples and creation of enabling community environments to encourage physical activity may be useful approaches in controlling the epidemic.
Genotype x Environment Interactions in Sugarcane under Irrigation for Agronomic Traits at Advanced Screening Stage in Ferké, Northern Ivory Coast
Authors: Péné Crépin B. , Béhou Yavo Michael
Published: March 2020

Background: The selection procedure of commercial sugarcane varieties introduced in Ivory Coast involves two different stages. Four varieties pre-selected at the first stage regarding a previous trial were due to be tested at the advanced stage.

Aims: The study aimed to determine the best performing sugarcane genotypes at the advanced selection stage under sprinkler irrigation, in comparison with to two check varieties (R579, SP70-1006).

Methodology: The same field experiment was carried out on two different locations in Ferké 2 sugar estate of Northern Ivory Coast. The experimental design used was a randomized complete block (RCB) with six cane genotypes in four replications. Every plot consisted of five dual rows of ten meters with 0.5 and 1.90 m of inter-row spacing, i.e. 95 m² per plot and about 3000 m² for each experiment. Both experiments were conducted over two seasons (plant cane and first ratoon) as early-season crops from early November, 2017 to mid-December, 2019. Over each micro-plot, data based on different agro-morphological traits were collected at harvest from three central dual rows.

Results: The study showed that most relevant traits in genotype clustering were related to juice quality (recoverable sucrose, sucrose content, purity), yields and yield components (Millable stalk number/ha, stalk height, stalk diameter, internode number). Based on sugar yields, two genotypes (N47, ECU01) superior to both check varieties were found promising with, respectively, 13.7 and 13.5 t sugar/ha. Their cane yield performances gave 124 and 123 t/ha, respectively, compared to 126.8 t/ha for the best performing check.

Conclusions: Not only sugar yield, but also flowering rate, stem borer infestation rate, stalk diameter, average stalk height and the number of tillers per hectare were found as the most relevant agronomic traits in the genetic variation of sugarcane genotypes tested. It came out also that GxE interactions were highly significant for five different traits, namely, cane and sugar yields, stalk borer infestation rate, fiber content and the average stalk height.

Aims: To evaluate the effects of organic amendment in the rehabilitation of two moribund cacao plantations at Ibadan (Oyo State) and Owena (Ondo State) using organic materials that included Cocoa Pod Husk (CPH) and Neem Leaf powder (NL).

Study Design: The experiment was laid out in a Randomized Complete Block Design in four replicates with four treatments which were CPH, CPH+NL (90:10), CPH+NL (80:20) and untreated.

Place and Duration of Study: Cocoa plantations at Ibadan and Owena, Nigeria between May, 2014 and Dec 2017.

Methodology: Initial soil sampling was done. Organic materials were applied to eight cacao trees in a ring at the base of trees in treated plots at the beginning of the rains in April/May and August/September. The treatments are: CPH Only @ 0.5 kg/tree, CPH Fortified with Neem Leaf (90:10) @ 0.45 kg + 0.05 kg/tree, respectively, CPH fortified with Neem Leaf (80:20) @ 0.40 kg + 0.10 kg/tree respectively. No application (control treatment).

Results: Eleven fungi species assigned to seven genera were recovered across the treatments. Organic amendments significantly (p<0.05) increased soil mineralization, microbial populations and pod production. After the second year of applications, CPH had the highest percentage of pod production over the control (64%) in Ibadan, while in Owena, CPH, CPH+NL (80:20) and CPH+NL (90:10) had percentage pod increase of 68, 64 and 63%, respectively, over the control. Organic materials had significant (p≤0.05) effect in raising the soil pH in the two locations from 6.41 to 6.82 in Owena and from 6.50 to 6.89 in Ibadan, compared to untreated soil.

Conclusion: The use of organic amendments in the rehabilitation of old and moribund cocoa (near death), improved soil nutrients as well as increased pod production and the microbial populations from the two plantations.

Published: March 2020

The motivation behind this investigation was to find out the relationship between competence and communication skills of human resources professionals and employee satisfaction, as mediating variables, to improve employee performance. This study also aimed to examine the direct relationship between competence and communication skills of human resources professionals and employee performance. For data collection, a questionnaire was sent to 60 employees from the level of Section Head to Senior Manager or those directly involved in the production process and other supporting functions. The result of this study showed that the competence level of human resources professionals did not have any significant relation with employee satisfaction and employee performance. In contrast, the communication skills of human resources professionals had a significant impact on employee satisfaction and indirect correlation with employee performance; employee performance increases if employee satisfaction increases. Consequently, to be able to increase employee satisfaction, HR professionals must improve their communication skills
Os fantasmas da maternidade: a importância da psicanálise no contexto hospitalar
Authors: De Albuquerque Amanda Pereira , De Sales Cecília Gardenia
Published: March 2020

Este artigo apresenta um estudo de caso realizado durante o estágio curricular no setor de Psicologia da maternidade do Hospital Agamenon Magalhães, Pernambuco. O caso foi de Valentina, gestante de alto risco, devido à um sopro cardíaco. O adoecimento durante a gestação restaurou um luto complicado em relação à suas figuras maternas, a mãe e avó que morreram  em situações parecidas, instaurando um medo de não sair com vida do hospital. A Psicanálise foi utilizada como método para resgatar a subjetividade dos pacientes dentro do contexto hospitalar, possibilitando um escuta qualificada e novas formas de elaborar o sofrimento psíquico. Como resultado das intervenções, na medida em que a relação terapêutica mesmo que breve foi construída, estabeleceu um setting terapêutico na postura do analista independente do ambiente de atendimento, permitindo que revisitasse o luto com segurança e ressignificasse a internação.

Para alcançar este objetivo, decidiu-se dividir este artigo em seções. A primeira tratou do processo de inserção da antropologia durante a formação dos discentes em medicina no semestre que possui como Eixo Temático Concepção e Nascimento, refletindo sobre os desafios que envolvem o aprender a relativizar práticas que se alicerçam na Medicina Baseada em Evidências (MBE). Posteriormente, em uma segunda seção, discutirá as reflexões suscitadas por uma experiência vivenciada durante atividade prática com um grupo de mulheres ativistas frente à causa do parto humanizado e a maternidade ativa. Por fim, em uma última seção, a possibilidade de uma reorientação do olhar sobre os aspectos culturais que envolvem a concepção, o nascimento, a mulher e o seu corpo.
Reprodução, Partos, Maternidades e Paternidades: Perspectivas Contemporâneas em Antropologia e Saúde
Authors: Neves Naiara Maria Santana , Lopes Giovanna De Carli
Published: March 2020

A maternidade compulsória e a naturalização do amor materno enquanto instintivo são alguns dos papéis atribuídos às mulheres a partir da modernidade (BADINTER, 1985). No mesmo sentido, passaram a emergir uma série de normas, condutas e imposições sobre o corpo da mulher, que encontraram no campo científico seu instrumento legitimador, sendo a dinâmica dos sistemas de saúde e da própria ciência construídas segundo a dinâmica das relações de gênero impostas na sociedade. A ginecologia e a obstetrícia, enquanto campos da ciência e prática de cuidado com a saúde e o corpo, são parte desta dinâmica social de diferenciação de sexos e de gêneros, e, desde o século XIX, atuam desde uma materialização e “substancialização da diferença” (Rohden, 2001, p. 13). Portanto, além das mulheres serem compelidas a conduzirem suas vidas em conformidade com a ordem namorar, casar e ter filhos, quando elas os têm, ainda enfrentam uma série de desafios, os quais buscamos abordar e visibilizar neste número especial sobre Reprodução, Partos, Maternidades e Paternidades.

The nicotinamide adenine dinucleotide (NAD+)/Sirtuin (SIRT) system is linked to metabolic adaptation. This study aimed to determine the temporal profile of metabolic responses of the liver to cold exposure and changes in the hepatic NAD+/SIRT system. Eight‐week‐old male C57BL/6 mice were individually housed in conventional cages under cold exposure (4 °C) for up to 5 days. Cold exposure decreased the hepatic triglyceride level and cholesterol level in mice by 1.7‐ and 1.6‐fold, respectively. Lipogenic gene expression was persistently reduced, while gluconeogenic gene expression was transiently increased. Hepatic NAD+/SIRT metabolism was induced during the ‘cold remodeling’ phase (days 1–3) and correlated with decreasing lipogenic and increasing gluconeogenic gene expression, contributing to the maintenance of whole‐body lipid and glucose homeostasis.
Evaluation of a neural network‐based photon beam profile deconvolution method
Authors: Mund Karl , Wu Jian , Liu Chihray , Yan Guanghua
Published: March 2020

Purpose

The authors have previously shown the feasibility of using an artificial neural network (ANN) to eliminate the volume average effect (VAE) of scanning ionization chambers (ICs). The purpose of this work was to evaluate the method when applied to beams of different energies (6 and 10 MV) and modalities [flattened (FF) vs unflattened (FFF)], measured with ICs of various sizes.

Methods

The three‐layer ANN extracted data from transverse photon beam profiles using a sliding window, and output deconvolved value corresponding to the location at the center of the window. Beam profiles of seven fields ranging from 2 × 2 to 10 × 10 cm2 at four depths (1.5, 5, 10 and 20 cm) were measured with three ICs (CC04, CC13, and FC65‐P) and an EDGE diode detector for 6 MV FF and FFF. Similar data for the 10 MV FF beam was also collected with CC13 and EDGE. The EDGE‐measured profiles were used as reference data to train and test the ANNs. Separate ANNs were trained by using the data of each beam energy and modality. Combined ANNs were also trained by combining data of different beam energies and/or modalities. The ANN's performance was quantified and compared by evaluating the penumbra width difference (PWD) between the deconvolved and reference profiles.

Results

Excellent agreement between the deconvolved and reference profiles was achieved with both separate and combined ANNs for all studied ICs, beam energies, beam modalities, and geometries. After deconvolution, the average PWD decreased from 1–3 mm to under 0.15 mm with separate ANNs and to under 0.20 mm with combined ANN.

Conclusions

The ANN‐based deconvolution method can be effectively applied to beams of different energies and modalities measured with ICs of various sizes. Separate ANNs yielded marginally better results than combined ANNs. An IC‐specific, combined ANN can provide clinically acceptable results as long as the training data includes data of each beam energy and modality.

Published: March 2020

As a kind of artificial surface composed of subwavelength meta‐atoms, metasurface has shown great potential in full vectorial electromagnetic manipulation. Here, a dual‐functional metasurface that is capable of generating 97% linear dichroism and 87% circular dichroism in the infrared region is proposed. The two functionalities can be achieved simultaneously under incident light of vertical azimuthal angles. Subsequent simulations demonstrate that the giant dichroism is induced by symmetry breaking of the structure under oblique incidence. Compared with single‐functional metasurfaces, this device exhibits better performance and more functionalities without the sacrifice of compactness. It is believed that this dual‐functional metasurface with simple geometry can find many potential applications in various fields, ranging from analytical chemistry and imaging to sensing and spectroscopy.

Published: March 2020

A class of anisotropic, transmissive electromagnetic metasurfaces is presented, which enable independent and simultaneous control of copolarized phase and amplitude responses to two linear, orthogonal polarizations. By varying the geometrical parameters, the transmission response of the proposed structure can yield a full phase coverage, accompanied by broadly adjustable amplitude and negligible cross‐polarized components. The full amplitude‐phase control together with the novel anisotropic character allows efficient implementation of complicated field manipulations. As representative application examples, which cannot be realized via conventional (phase‐only) metasurfaces, it is presented here: (1) the radiation of multiple equal‐power vortex beams (along arbitrarily predesigned directions, with designable orbital angular momentum modes under different polarizations), and (2) the realization of polarization‐reconfigurable multifocal metalenses. Full‐wave numerical simulations and experimental results demonstrate good agreement and confirm the versatility and effectiveness of the proposed approach to design advanced field‐manipulation systems.
Reflective Polarization Volume Lens with Small f‐Number and Large Diffraction Angle
Authors: Yin Kun , He Ziqian , Wu Shin‐Tson
Published: March 2020

Planar optics based on patterned cholesteric liquid crystals (CLCs) has attracted increasing attention owing to the self‐organized helical structure and the ability to create arbitrary reflected wavefront through spatial orientation control. However, because of the subwavelength‐orientation requirement, it is challenging for liquid crystal lens to achieve a low f‐number (f/#) and large deflection angle simultaneously. Furthermore, with the increasing demand for compact size in novel optical systems, reflective lens has advantage over the transmissive one because it can fold the optical path. Here, a new off‐axis reflective polarization volume lens (PVL) with f/# = 0.825, large aperture size, simple fabrication process, thin profile, circular polarization selectivity, and large diffraction angle is proposed. In contrast to traditional vertical spiral structure, PVL is based on patterned CLCs with a slanted helical axis. In this paper, the PVL is theoretically evaluated and then three reflective PVLs at red, green, and blue wavelengths (R = 605 nm, G = 532 nm, and B = 450 nm) are fabricated. Meanwhile, a simple approach is utilized to achieve 20 mm diameter and 16.5 mm focal length. The low scattering and good image quality of reflective PVL enrich these functional devices and provide promising applications to novel foldable optical systems and waveguide‐based wearable near‐eye displays.

A series of F‐substituted Na2/3Ni1/3Mn2/3O2−xFx (x = 0, 0.03, 0.05, 0.07) cathode materials have been synthesized and characterized by solid‐state 19F and 23Na NMR, X‐ray photoelectron spectroscopy, and neutron diffraction. The underlying charge compensation mechanism is systematically unraveled by X‐ray absorption spectroscopy and electron energy loss spectroscopy (EELS) techniques, revealing partial reduction from Mn4+ to Mn3+ upon F‐substitution. It is revealed that not only Ni but also Mn participates in the redox reaction process, which is confirmed for the first time by EELS techniques, contributing to an increase in discharge specific capacity. The detailed structural transformations are also revealed by operando X‐ray diffraction experiments during the intercalation and deintercalation process of Na+, demonstrating that the biphasic reaction is obviously suppressed in the low voltage region via F‐substitution. Hence, the optimized sample with 0.05 mol f.u.−1 fluorine substitution delivers an ultrahigh specific capacity of 61 mAh g−1 at 10 C after 2000 cycles at 30 °C, an extraordinary cycling stability with a capacity retention of 75.6% after 2000 cycles at 10 C and 55 °C, an outstanding full battery performance with 89.5% capacity retention after 300 cycles at 1 C. This research provides a crucial understanding of the influence of F‐substitution on the crystal structure of the P2‐type materials and opens a new avenue for sodium‐ion batteries.

Influence of local density and sex ratio on pollination in an ambophilous flowering plant
Authors: Timerman David , Barrett Spencer C. H.
Published: March 2020

Premise

Variation in local density and sex ratio in dioecious plants can affect mating success through the actions of pollen vectors, principally generalist insects or wind. Increased density and male‐biased sex ratios should promote pollen transfer and seed production, but their combined effects have not been investigated for ambophilous species, which exhibit both insect and wind pollination.

Methods

We manipulated density (low vs. high) and sex ratio (1:1 vs. 3:1 male‐biased) in arrays of dioecious ambophilousThalictrum pubescens. We quantified visitation rates and foraging times to examine whether pollinators exhibited sex‐specific preferences and determined the seed set of arrays.

Results

Pollinators visited more plants per foraging bout at high than low density. Visitation rates and foraging times of visitors were greater for male than for female plants but did not depend on the density or sex ratio of arrays. However, whereas solitary bees displayed a strong preference for males, hover flies were indifferent to plant sex phenotype. Solitary bees also visited significantly more plants per foraging bout than hover flies. There was a significant interaction between density and sex ratio on seed set. At low density, seed set was greater for 3:1 than for 1:1 arrays, but at high density the opposite pattern occurred.

Conclusions

The demographic factors we investigated had complex influences on pollinator foraging behavior and patterns of seed set. Several factors may explain our results, including the influence of density and sex ratio on pollen export from arrays, grooming by pollinators, and the contribution of wind pollination.
