High-resolution wavemeter using Rayleigh speckle obtained by optical time domain reflectometry
Authors: Wan Yangyang , Wang Shuai , Fan Xinyu , Zhang Zhaopeng , He Zuyuan
Published: January 2020

The characteristics of Rayleigh speckle generated from a single-mode fiber are related to the wavelength of the incident lightwave, which makes it possible to use Rayleigh speckle for spectrum measurement. Based on this feature, we propose, to the best of our knowledge, a novel wavemeter with high resolution realized using optical time domain reflectometry to obtain Rayleigh speckle. We show that the spectral resolution is inverse to the probe pulse width, with a spectral resolution of 6 fm corresponding to a 2 µs probe pulse. A correlation coefficient method is introduced to further increase the spectral resolution from 6 to 0.4 fm. Moreover, it is experimentally demonstrated that the system has the capability to resolve dynamic multi-wavelength signals with 25 µs time resolution. The proposed high-resolution wavemeter is a good prospect for cost effectiveness, compactness, and excellent performance of spectral resolution.

Published: January 2020

We report, for the first time, to the best of our knowledge, a femtosecond mode-locked Fe:ZnSe laser. Passive mode locking is implemented using graphene as a saturable absorber. The laser operates at 4.4 µm with a repetition frequency of 100 MHz and 415 mW output power pumped by a fiber 7 W Er:ZBLAN laser. The pulse duration of about 732 fs is retrieved from the first-order autocorrelation function. Additionally, we observe pulsed nanosecond oscillation under continuous-wave pumping and strong amplitude modulation caused by Kerr self-focusing. This Letter fills the gap in operating regimes of Fe:ZnSe lasers and paves the way for the development of powerful ultrafast high-repetition-rate mid-IR sources for the most advanced fields of science.
In situ observation of slow and tunnelling light at the cutoff wavelength of an optical fiber
Authors: Yang Yong , Sumetsky M.
Published: January 2020

Slow waves and tunneling waves can meet at the cutoff wavelengths and/or the transmission band edges of optical and quantum mechanical waveguides. The experimental investigation of this phenomenon, previously performed using various optical microstructures, is challenged by fabrication imperfections and material losses. Here, we demonstrate this phenomenon in situ for whispering gallery modes slowly propagating along a standard optical fiber, which possesses a record uniformity and exceptionally small transmission losses. The slow axial propagation dramatically increases the longitudinal wavelength of light and allows us to measure nanosecond-long tunneling times along tunable potential barriers having the width of hundreds of micrometers. This demonstration paves a simple and versatile way to investigate and employ the interplaying slow and tunneling light.
Generation of Hofstadter’s butterfly spectrum using circular arrays of microring resonators
Authors: Zimmerling Tyler J. , Van Vien
Published: January 2020

Hofstadter’s butterfly spectrum, which characterizes the energy bands of electrons in a 2D lattice under a perpendicular magnetic field, has been emulated and experimentally characterized in periodic bandgap structures at microwave and acoustic frequencies. However, measurement of the complete spectrum at optical frequencies has yet to be demonstrated. Here, we propose a simple topological photonic structure based on a circular array of microrings with periodic resonant frequency detunings that can be implemented on an integrated optics platform. We show that this ring-of-rings structure exactly emulates the Harper equation and propose an experimental approach for measuring Hofstadter’s butterfly spectrum at optical frequencies.
Mapping a quantum walk by tuning the coupling coefficient
Authors: Ng Kian Fong , Rodrigues Manuel J. L. F. , Viana-Gomes José , Ling Alexander , Grieve James A.
Published: January 2020

We present a method to map the evolution of photonic quantum walks that is compatible with nonclassical input light. Our approach leverages a newly developed flexible waveguide platform to reconfigure the jumping rate between spatial modes, allowing the observation of a range of evolution times in a chip of fixed length. In a proof-of-principle demonstration, we reconstruct the evolution of photons through a uniform array of coupled waveguides by monitoring the end-face while tuning the device. This approach enables direct observation of mode occupancy at arbitrary resolution, extending the utility of photonic quantum walks for quantum simulations and related applications.
Tight-focusing properties of linearly polarized circular Airy Gaussian vortex beam
Authors: Zhuang Jingli , Zhang Liping , Deng Dongmei
Published: January 2020

We show the tight-focusing properties of a linearly polarized circular Airy Gaussian vortex beam (CAiGVB) with a high-numerical-aperture objective lens; the light intensity distributions exhibit diversity with different positions of the vortex pairs (on-axis or off-axis vortex pairs). By choosing different optical distribution factors, the CAiGVB turns into a circular Airy vortex beam or Gaussian vortex beam, and the depth of focus can also be controlled. It is known that the vortex beam possesses both orbital and spin angular momentum. The spin density vector changes its direction in three-dimensional space during beam propagation, as long as it is not purely transverse or longitudinal, which would cause 3D polarization ellipse topologies. In contrast, the polarization topologies degenerate into 2D when the spin density vector is purely transverse or longitudinal. Furthermore, the direction of the spin density vector is closely related to the Gouy phase difference between longitudinal and transverse electric field components of the vectorial beam.
UKURAN PERTAMA KALI MATANG GONAD DAN SELEKTIVITAS JARING INSANG IKAN NILA (Oreochromis niloticus) DI WADUK JATILUHUR, JAWA BARAT
Authors: Warsa Andri , Astuti Lismining Pujiyani
Published: January 2020

A gillnet is a common fishing gear for exploitation and fish capture at Jatiluhur Reservoir. The fish size captured by the gillnet depends on the mesh size for its selective fishing gear. Determination of gillnet mesh size is one of effort for fisheries management.  The management of nile tilapia (Oreochromis niloticus) is based on gillnet selectivity and reproductive biology of nile tilapia. The aim of the research was to estimate length at the first mature (Lm) and gillnet selectivity for nile tilapia. The research was conducted at February-September 2017 through experimental fishing using gillnet with 1.0–4.0 mesh size (interval 0.5 inch). The gillnet installation was performed at six stations, namely Cihuni-Cibadak, Sungai Cikanyayan, Sungai Ciririp, Sungai Cihonje, Pasir Kole and Cilalawi. The Lm of nile tilapia was 18.3 and 23.3 cm for female and male, respectively. The total length retained in the gillnet with the highest probability for mesh size 1.0; 1.5; 2.0; 2.5; 3.0; 3.5 and 4.0 inches were 9.5; 12.5; 14.5; 18.5; 20.5; 26.5 and 30.5 cm, respectively. The minimum mesh size used for nile tilapia exploitation was ≥3 inches because it was able to catch nile tilapia with the total length larger than Lm (Lc>Lm) and with an SPR value of > 40% so that the tilapia resource in the Jatiluhur Reservoir remains sustainable.

Authors: Napitupulu Toga Pangihotan , Kanti Atit , Sudiana I Made
Published: January 2020

The objective of the study was to isolate microorganism that can produce growth hormone, fix atmospheric nitrogen, and solubilize inorganic phosphate that may be used for enhancing the growth of banana in marginal land.  A total of 25 bacteria associated with banana that belonged to six genera were isolated from namely Acinetobacter, Enterobacter, Pantoea, Klebsiella, Rhizobium, and Cupriavidus genera. Gammaproteobacteria is the dominant class, followed by Betaproteobacteria and Alphaproteobacteria. All isolates were screened for multiple plant growth promoting traits which may play a role in banana growth, namely fixing nitrogen, solubilizing phosphate, and producing Indole Acetic Acid (IAA). Twenty-two isolates were capable to fix nitrogen, 21 isolates can solubilize insoluble phosphate, and 15 isolates produced IAA dependent of L-Tryptophan presence. Despite most of the bacteria isolates exhibited one plant growth-promoting activities, Enterobacter and Klebsiella genera showed three of plant growth promoting bacteria traits.
REVIEW- INDONESIAN FLYING FOXES: RESEARCH AND CONSERVATION STATUS UPDATE
Authors: Tsang Susan M , Wiantoro Sigit
Published: January 2020

Flying foxes are important ecological keystone species on many archipelagoes, and Indonesia is home to over a third of all flying fox species globally. However, the amount of research on this clade belies their importance to natural systems, particularly as they are increasingly threatened by anthropogenic development and hunting. Here, we provide a review of the literature since the publication of the Old World Fruit Bat Action Plan and categorize research priorities as high, medium, or low based on the number of studies conducted. A majority of the research priorities for Indonesian endemics are categorized as medium or high priority. Low priority ratings were in multiple categories for widespread flying fox species found throughout Southeast Asia, though much of the data were from outside of the Indonesian extent of the species range. These research gaps tend to highlight broader patterns of research biases towards western Indonesia, whereas significant research effort is still needed in eastern Indonesia, particularly for vulnerable island taxa.
NEW RECORDS AND REDESCRIPTION OF LABIDOCERA ROTUNDA MORI, 1929 (COPEPODA, CALANOIDA, PONTELLIDAE) FROM SEBATIK ISLAND, NORTH KALIMANTAN, INDONESIA, WITH NOTES ON ITS SPECIES-GROUP
Authors: Mulyadi Mulyadi
Published: January 2020

During a plankton trip around Sebatik Island, North Kalimantan, a copepod Labidocera rotunda Mori, 1929 (Calanoida, Pontellidae) was collected for the first time in Indonesian waters. Both sexes are redescribed and compared to previous descriptions. The geographical distribution of the species confirms that it is of Indo-Pacific origin. There has been a mix-up between L. rotunda described by Mori (1929) from Pusan, Korea and L. bipinnata from Sagami Bay, described by Tanaka (1936). Fleminger et al. (1982) have argued that the minor difference is based on the presence or absence of cephalic hooks and had synonymized L. bipinnata with L. rotunda.

Climate change impacts on cattle production: analysis of cattle herders’ climate variability/change adaptation strategies in Nigeria
Authors: Ayanlade Ayansina , Ojebisi Stephen M.
Published: January 2020

The study examines the seasonality in climate and extreme weather events, and its effect on cattle production in the Guinea Savannah ecological zone of Nigeria. The study uses both quantitative and qualitative approaches. Climate data of 34 years were used to examine the trends in rainfall pattern and climate variability while household survey was used to appraise the herders’ awareness of climate variability/change impacts and adaptation strategies. Cumulative Departure Index (CDI) method was used to assess the extreme weather events while descriptive statistics and multinomial logistic (MNL) regression model were used to identify the factors that determined herders’ adaptation strategies to climate change. The results revealed a significant spatiotemporal variation in both rainfall and temperature with CDI ranging from -1.39 to 3.3 and -2.3 to 1.81 respectively. The results revealed a reduction in the amount of water available for cattle production. From survey results, 97.5% of the herders identified drought as the major extreme weather event affecting livestock productivities in the study region. In the herder’s perception, the droughts are more severe in recent years than 34 years ago. The results from MNL revealed that extreme weather events, such as drought, has a positive likelihood on migration, at a 10% level of significance, the events has led to migration of cattle herders from the northern part of the study area toward the southern part in recent years.
Hybrid Learning Spaces for Design Thinking
Authors: Kohls Christian
Published: January 2020

As design thinking becomes more and more important in higher education, we need to think about ways to enable educators and students to learn about the concepts and apply them to their own projects. One approach is to create hybrid learning spaces with tools that support design thinking and offer affordances for the various methods, ways of working and thinking. Hybridity dissolves existing dichotomies such as physical-digital, formal-informal, learning-teaching and individual-collective. This article introduces design principles and patterns to develop such spaces for university campuses. We will describe how we identified, applied and tested them. Based on these findings we can provide recommendations for planning new hybrid spaces for design thinking at other universities.
Applicability of NGGM near-real time simulations in flood detection
Authors: Purkhauser A. F. , Koch J. A. , Pail R.
Published: January 2020

The GRACE mission has demonstrated a tremendous potential for observing mass changes in the Earth system from space for climate research and the observation of climate change. Future mission should on the one hand extend the already existing time series and also provide higher spatial and temporal resolution that is required to fulfil all needs placed on a future mission. To analyse the applicability of such a Next Generation Gravity Mission (NGGM) concept regarding hydrological applications, two GRACE-FO-type pairs in Bender formation are analysed. The numerical closed loop simulations with a realistic noise assumption are based on the short arc approach and make use of the Wiese approach, enabling a self-de-aliasing of high-frequency atmospheric and oceanic signals, and a NRT approach for a short latency.

Numerical simulations for future gravity mission concepts are based on geophysical models, representing the time-variable gravity field. First tests regarding the usability of the hydrology component contained in the Earth System Model (ESM) by the European Space Agency (ESA) for the analysis regarding a possible flood monitoring and detection showed a clear signal in a third of the analysed flood cases. Our analysis of selected cases found that detection of floods was clearly possible with the reconstructed AOHIS/HIS signal in 20% of the tested examples, while in 40% of the cases a peak was visible but not clearly recognisable.
Technical Efficiency of African Indigenous Vegetable Production in Vhembe District of Limpopo Province, South Africa
Authors: Mulaudzi V. S. , Oyekale A.S. , Ndou P.
Published: January 2020

African indigenous vegetables (AIVs) have long been known in South African rural communities as essential food that is being consumed with starchy staples, and their consumption has increased over the past few decades. There is now a growing interest and awareness of AIVs due to their nutritional benefits and outstanding potential to generate farm incomes. However, several factors are militating against their production along the supply chains of value addition. This study analysed the technical efficiency of AIVs production in Vhembe district of Limpopo province. The data were collected from 114 AIVs farmers through a multi-stage sampling technique. Data analysis was carried out using Stochastic Frontier model via the Cobb-Douglas production function. The results revealed that the average age and years of farming experiences of the farmers were 59.6 and 30.9 years respectively. About 84% of the farmers lacked access to formal credit, while 92% had access to extension services. Elasticity values of land area cultivated, fertiliser, seeds, labour and tractor days in relation to AIV production were 0.4441, 0.1749, 0.1311, 0.2663 and 0.2360 respectively. Furthermore, the results revealed that average technical efficiency in the production of indigenous vegetables was 0.79%. The variables that significantly influenced technical inefficiency were years of schooling, extension services, gender and access to the irrigation system. In conclusion, production of AIV exhibits decreasing returns to scale. However, promotion of AIV production and efficiency requires consideration of gender issues in accessing resources, educational attainments of farmers, access to irrigation services and proper reorientation of the components of agricultural extension services delivery in order to benefit AIV farmers.
Espaço Público e Vivência Da Santidade
Authors: Andrietta José Reginaldo
Published: January 2020

Esta reflexão sobre a vivência da santidade no espaço público, inspirada no Magistério da Igreja, especialmente na Exortação Apostólica Gaudete et Exsultate, do Papa Francisco, sugere, sob a perspectiva de uma teologia praxiológica contextualizada, a compreensão de santidade muito além da espiritualidade pessoal. A santidade sob a perspectiva da mística cristã deve permear a vida em sociedade, supondo engajamento pastoral de cunho sócio-político, orientado pela primazia do Bem Comum, princípio fundamental da Doutrina Social da Igreja, que se contrapõe ao privilégio que nossa sociedade confere aos interesses particulares imiscuídos no espaço público. A “grande regra” para a vivência da santidade nesse espaço é a caridade, traduzida em ação política que visa estabelecer sistemas sociais e econômicos justos, sinais históricos do Reino de Deus, que é, também, escatológico.

Published: January 2020

O artigo tem por objetivo problematizar porque a Pedagogia do oprimido é uma referência permanente para a educação popular e para a educação de jovens e adultos. A atualidade da obra foi analisada a partir de três dimensões: o popular na educação, o pensar crítico e a revolução cultural. As análises evidenciam que, apesar da educação de jovens e adultos estar longe de cumprir com seu papel reparador no Brasil, o caráter dialógico e humanizador da pedagogia freireana continua presente nas práticas pedagógicas. A Pedagogia do oprimido pode ser uma referência tanto como uma orientação ético-política quanto uma matriz teórico-prática.

Fixing multicollinearity in modelling market body weight of Sudani ducks (Cairina moschata) from early age morphometric traits
Authors: Oguntunji A.O. , Makram A.
Published: January 2020

Abstract: Morphometric parameters and their indices are central to characterization, selection and genetic improvement of farm animals. The present study was conducted to fix multicollinearity among predictors and to fit optimum regression model for prediction of 14-week body weight of 150 un-sexed Sudani ducks from early age (0, 2, 4 and 6 weeks of age) morphometric measurements (body weight, body length, breast circumference and keel length). Pairwise correlation between the 14-week body weight (BWT) and measured variables was the highest with 2-week BWT (r=0.934, P<0.001). Application of multicollinearity diagnostics (variance inflation factor, tolerance, eigenvalues and condition index) revealed collinearity among six variables. Stepwise regression equation identified 2-week BWT as the most important predictor accounting for 87.30% of the total variation of the response variable. However, the optimum regression model for prediction of adult body weight was fitted with 2-week BWT in quadratic model having the highest predictive power (Coefficient of determination /R2/=0.966 and least root mean square error /RMSE/=4.269). This result is applicable under field conditions for both researchers and duck farmers for early selection of 14-week market body weight of Sudani ducks at 2 weeks of age.

The most attention are concentrated on the data of antibody-producing cell genomic editing to increase the yield of the product, the stability of expression of the recombinant protein and reduce its immunogenicity. Modern methods of site-directed modification (zinc finger method, TALEN and CRISPR/CAS9) for editing the genome of the CHO cell line are analyzed. The strategies of genomic editing choice carrying out taking into account the advances of omix technologies are discussed. Approaches to increase the life span of producer cells are considered, including an increase in the expression of anti-apoptotic signals and the deletion of proapoptotic genes, an increase in the duration of the cell cycle of cells in the G0/G1 phase. The approaches used to regulate the posttranslational modification of monoclonal antibodies are considered. Significant part of the review are devoted to the discussion of the spesificity and differences of glycosylation, galactosylation and sialization of monoclonal antibodies in different expression systems and the associated different degree of immunogenicity of monoclonal antibodies. The main approaches to the regulation of the synthesis of monoclonal antibodies at the stage of translation using non-coding RNA are considered.

BACKGROUND: The three-year survival rate of patients with ischemic cardiomyopathy (ICMP) is 535 %; its pathogenesis is poorly understood. Violation of cytokine-dependent differentiation of monocytes/macrophages involved in atherogenesis may play an important role in the development of ICMP.
AIMS: To characterize the disorders of monocytes subpopulation composition and mediators spectrum of blood in patients with coronary heart disease (CHD), associated with the development of ICMP.
METHODS: A one-stage, clinical, controlled (case-control) study was conducted from February 2017 to December 2018. 45 patients with CHD (all men), who were in a cardiac surgery hospital, were examined before coronary bypass surgery: 19 people suffering from ICMP, and 26 people who do not suffer from ICMP, as well as 14 healthy men. In the blood of the examined individuals CD14++CD16-, CD14++CD16+, CD14+CD16++ and CD14+CD16- monocytes were determined with respect to all CD14-positive cells by flow cytometry, in blood plasma ― concentration of galectin 2 and 9, IL-4, IL-10, IFN-, M-CSF, HIF-1 by enzyme-linked immunosorbent assay (ELISA).
RESULTS: The development of the ICMP accompanied by deficiency of HIF-1 and CD14+CD16++ monocytes (0.037 [0.020; 0.045] ng/ml, p = 0.019, and 5.05 [4.08; 6.58] %, p = 0.011) in combination with an excess of IL-10 (30.05 [24.75; 33.50] ng/ml, p = 0.042) in the blood. It is shown in blood of patients without ischemic cardiomyopathy the increase in the content of CD14++CD16+ cells and lack of CD14+CD16- monocytes (25.27 [15.78; 31.39] %, p = 0.038, and 2.68 [2.63; 4.09] %, p = 0.027) at normal concentration of IL-10 and HIF-1. In patients with CHD and ischemic cardiomyopathy and without ICMP in the blood the concentration of M-CSF and galectin-2 (2.00 [1.21; 3.24] pg/ml, p = 0.028, and 0.40 [0.12; 2.37] ng/ml, p = 0.004; 3.00 [1.90; 4.05] pg/ml, p = 0.003, and 3.20 [2.07; 4.00] ng/ml, p = 0.002, respectively) is reduced at normal content of galectin-9, and CD14++CD16- monocytes. IL-4 and IFN- in blood plasma are not determined (zero values).
CONCLUSIONS: The development of ICMP is associated with excess of IL-10 and HIF-1 deficiency, which is accompanied by inhibition of CD14+CD16++ monocytes maturation.
Identifying Critical Contextual Design Cues Through a Machine Learning Approach
Authors: Cummings Mary L. “Missy” , Stimpson Alexander
Published: January 2020

Given the rise of autonomous systems in transportation, medical, and manufacturing industries, there is an increasing need to understand how such systems should be designed to promote effective interactions between one or more humans working in and around these systems. Practitioners often have difficulties in conducting costly and time‐consuming human‐in‐the‐loop studies, so an analytical strategy that helps them determine whether their designs are capturing their planned intent is needed. A traditional top‐down, hypothesis‐driven experiment that examined whether external displays mounted on autonomous cars could effectively communicate with pedestrians led to the conclusion that the displays had no effect on safety. However, by first taking a bottom‐up, data‐driven machine learning approach, those segments of the population that were most affected by the external displays were identified. Then, a hypothesis‐driven, within‐subjects analysis of variance revealed that an external display mounted on an autonomous car that provided the vehicle's speed as opposed to commanding a go/no‐go decision provided an additional 4 feet of safety for early adopters. One caveat to this approach is that the selection of a specific algorithm can significantly influence the results and more work is needed to determine the sensitivity of this approach with seemingly similar machine learning classification approaches.

Study of strength and stability of a composite transmission tower
Authors: Bhowmik Chiranjit , Chakraborti Prasun
Published: January 2020

This research study reports a finite-element (FE) analysis undertaken to determine the strength and stability of a transmission tower constructed with a carbon-fibre-reinforced epoxy composite under different loading conditions. The loading conditions such as wind, weight of wires and self-weight of structures were calculated manually and applied in the FE model. Different loading conditions including the broken wire condition (BWC) were innovatively considered in this paper. The results showed that at the transmission tower, the components near to the base of the structure had much less  longitudinal stress. At different loading conditions, including BWC, the composite material was found to be competent. An innovative design approach incorporating stability analysis was found to be appropriate for determining the stability and structural safety of the tower.

The studies were carried out in the problematic of improving the tools for implementing economic policy which ensure widespread use of strategic planning and regulation methods in real practice of managing the territorial systems development at various levels. The article highlights the most pressing problems of improving the efficiency of socio-economic development planning for territorial systems, including in the context of the modern digital economy development. The need for implementation analytical processing systems and the management information effective use to substantiate strategic decisions is indicated as the priority problem. The comparative assessment of the well-known methodologies, methods and ready-made software solutions in modeling the economy of territorial socio-economic system at the different levels is carried out. Their strengths and weaknesses are identified for solving the identified problems and priority tasks of territorial development. The basic principles and requirements are formulated for the territorial socio-economic system’s development predicting tools. The conceptual scheme for implementing the simulation model is proposed. In general terms, the scheme provides the adaptation of the SAM methodology to formalize economic agents’ expenses and incomes balance. At the same time it involves the use of econometric methods, fuzzy logic theory and soft computing algorithms. The statement of the simulation problem is considered, the structure and the block’s relations logic for the simulation model are described. It is proposed to formalize the basic parameters connections of the model in two groups: in the first group the system relations of the model parameters are identified and formalized by SAM methodology; in the second group the factor relations are identified and formalized using econometric methods. Some results of forecasting calculations are given as part of the substantiation of the strategy for socio-economic development of the of Ufa city for the period until 2030.
