Published: November 2019

AbstractAphid-parasitoid interactions have been widely used as a model system in research studies on the structure and functions of arthropod food web. Research on aphid-parasitoid food webs is hindered by their micromorphological characteristics and the high amount of labor associated with their development. Species-specific primers for cotton aphids and their parasitoids were designed and integrated into two multiplex PCRs and six singleplex PCRs, and all PCRs were optimized to achieve high specificity and sensitivity (100–10,000 DNA copies). One cotton aphid (Aphis gossypii) as well as three primary parasitoid and seven hyperparasitoid species or genera were detected using this molecular approach. This group comprises all the primary parasitoids and 97.2–99.6% of the hyperparasitoids reported in cotton fields in northern China. A tritrophic aphid-primary parasitoid-hyperparasitoid food web was then established. The described method constitutes an efficient tool for quantitatively describing the aphid-primary parasitoid-hyperparasitoid food webs and assessing the efficiency of the biological control of parasitoids in cotton fields in northern China.
Engel’s law in the commodity composition of exports
Authors: Choi Sung-Gook , Lee Deok-Sun 
Published: November 2019

AbstractDifferent shares of distinct commodity sectors in production, trade, and consumption illustrate how resources and capital are allocated and invested. Economic progress has been claimed to change the share distribution in a universal manner as exemplified by the Engel’s law for the household expenditure and the shift from primary to manufacturing and service sector in the three sector model. Searching for large-scale quantitative evidence of such correlation, we analyze the gross-domestic product (GDP) and international trade data based on the standard international trade classification (SITC) in the period 1962 to 2000. Three categories, among ten in the SITC, are found to have their export shares significantly correlated with the GDP over countries and time; The machinery category has positive and food and crude materials have negative correlations. The export shares of commodity categories of a country are related to its GDP by a power-law with the exponents characterizing the GDP-elasticity of their export shares. The distance between two countries in terms of their export portfolios is measured to identify several clusters of countries sharing similar portfolios in 1962 and 2000. We show that the countries whose GDP is increased significantly in the period are likely to transit to the clusters displaying large share of the machinery category.

Published: November 2019

AbstractSome lung and ovarian tumors are connected to the loss of expression of SMARCA4 gene. In its promoter region, a 44-nucleotides long guanine sequence prone to form G-quadruplex structures has been studied by means of spectroscopic techniques (circular dichroism, molecular absorption and nuclear magnetic resonance), size exclusion chromatography and multivariate analysis. The results have shown that the central 21-nucleotides long sequence comprising four guanine tracts of disparate length is able to fold into a pH-dependent ensemble of G-quadruplex structures. Based on acid-base titrations and melting experiments of wild and mutated sequences, the formation of a C·C+ base pair between cytosine bases present at the two lateral loops is shown to promote a reduction in conformational heterogeneity, as well as an increase in thermal stability. The formation of this base pair is characterized by a pKa value of 7.1 ± 0.2 at 20 °C and 150 mM KCl. This value, higher than those usually found in i-motif structures, is related to the additional stability provided by guanine tetrads in the G-quadruplex. To our knowledge, this is the first thermodynamic description of this base pair in loops of antiparallel G-quadruplex structures.

Published: November 2019

AbstractGermline variants such as BRCA1/2 play an important role in tumorigenesis and clinical outcomes of cancer patients. However, only a small fraction (i.e., 5–10%) of inherited variants has been associated with clinical outcomes (e.g., BRCA1/2, APC, TP53, PTEN and so on). The challenge remains in using these inherited germline variants to predict clinical outcomes of cancer patient population. In an attempt to solve this issue, we applied our recently developed algorithm, eTumorMetastasis, which constructs predictive models, on exome sequencing data to ER+ breast (n = 755) cancer patients. Gene signatures derived from the genes containing functionally germline variants significantly distinguished recurred and non-recurred patients in two ER+ breast cancer independent cohorts (n = 200 and 295, P = 1.4 × 10−3). Furthermore, we compared our results with the widely known Oncotype DX test (i.e., Oncotype DX breast cancer recurrence score) and outperformed prediction for both high- and low-risk groups. Finally, we found that recurred patients possessed a higher rate of germline variants. In addition, the inherited germline variants from these gene signatures were predominately enriched in T cell function, antigen presentation, and cytokine interactions, likely impairing the adaptive and innate immune response thus favoring a pro-tumorigenic environment. Hence, germline genomic information could be used for developing non-invasive genomic tests for predicting patients’ outcomes in breast cancer.

Published: November 2019

AbstractTheir exceptional optical properties are a driving force for the persistent interest in atomically thin transition metal dichalcogenides such as MoS2. The optical response is dominated by excitons. Apart from the bright excitons, which directly couple to light, it has been realized that dark excitons, where photon absorption or emission is inhibited by the spin state or momentum mismatch, are decisive for many optical properties. However, in particular the momentum dependence is difficult to assess experimentally and often remains elusive or is investigated by indirect means. Here we study the momentum dependent electronic structure experimentally and theoretically. We use angle-resolved photoemission as a one-particle probe of the occupied valence band structure and electron energy loss spectroscopy as a two-particle probe of electronic transitions across the gap to benchmark a single-particle model of the dielectric function $$\epsilon ({\bf{q}},\omega )$$

Published: November 2019

AbstractSparidae (Teleostei: Spariformes) are a family of fish constituted by approximately 150 species with high popularity and commercial value, such as porgies and seabreams. Although the phylogeny of this family has been investigated multiple times, its position among other teleost groups remains ambiguous. Most studies have used a single or few genes to decipher the phylogenetic relationships of sparids. Here, we conducted a thorough phylogenomic analysis using five recently available Sparidae gene-sets and 26 high-quality, genome-predicted teleost proteomes. Our analysis suggested that Tetraodontiformes (puffer fish, sunfish) are the closest relatives to sparids than all other groups used. By analytically comparing this result to our own previous contradicting finding, we show that this discordance is not due to different orthology assignment algorithms; on the contrary, we prove that it is caused by the increased taxon sampling of the present study, outlining the great importance of this aspect in phylogenomic analyses in general.

AbstractOne of the main challenges for the modern magnonics, which, as opposed to the conventional electronics, operates with quanta of spin waves in magnetically ordered materials—magnons—is energy efficient control of magnon transport on small time and space scales. The magnon propagation in a time-dependent periodic spatial potentials—dynamic magnonic crystals—paves a way to this aim. To date, dynamic manipulation of the magnonic crystals has been realized with electric current and optic control influence. However, both approaches show limited potential for reduction in energy consumption and miniaturization of magnonic circuits. Voltage (or electric field) control of magnon currents promises to be fast and low energy consuming. It can be achieved in ferrite-ferroelectric (multiferroic) heterostructures, where strong coupling of magnons and microwave photons constitutes new quasiparticles called electromagnons. Here, we present an experimental realization of a voltage-controlled dynamic electromagnonic crystal operating with electromagnons at microwave frequencies.
Charnley femoral cemented stem with a permeable and resorbable cement restrictor and low-viscosity cement
Authors: Prudhon Jean-Louis , Caton Jacques H. , Aslanian Thierry 
Published: November 2019

Introduction: In 1979, in his first book dealing with low-friction arthroplasty (LFA), Charnley highlighted the use of a cement restrictor. Breusch and Malchau described in 2005 the “second-generation cementing technique.”
The main objective of this study was to report on the clinical survival of 100 cases of Charnley femoral component implanted in 2007 and 2008 using a permeable and resorbable cement restrictor and a low-viscosity antibiotic-loaded cement.
The secondary objectives were to analyze the complications and side effects and the accuracy of the device positioning.
Material and methods: This was a monocentric retrospective review of a prospectively compiled database.
Diaphyseal restrictor was biodegradable and permeable to gas, blood, and fluids to avoid intramedullary over pression during cementation. The cement was a low-viscosity antibiotic-loaded cement.
Among 3555 patients, we selected the first continuous 100 cases of patients where we implanted the device.
Survival probability was computed according to Kaplan–Meier method.
Results: Mean follow-up was 6.55 ± 2.6 (range 1–11).
Considering femoral component revision as the endpoint, survival rate was 100%.
No patients died intraoperatively, none in the first month and the first year after surgery.
No early periprosthetic fractures have been reported.
Discussion: As described initially by Charnley, the use of a cement restrictor was highly recommended through the different generations of cementing techniques.
Hypotensive episodes and cardiac arrest have been reported during cement insertion.
In our series, we did not deplore any adverse effect related to the cementation.
Conclusion: Our study demonstrates a 100% survival rate of a cemented femoral component without adverse effects when using routinely a resorbable and permeable cement restrictor and a low-viscosity cement. Bone cement is still a fantastic ally for the surgeon and the patients.

Published: November 2019

AbstractSystemic thrombolysis is increasingly used for management of arterial thrombosis following cardiac catheterization, and complications apart from bleeding manifestations are not well reported. We report the case of an infant with lower limb ischemia secondary to femoral arterial thrombosis, which developed after cardiac catheterization. Systemic thrombolysis resulted in successful reperfusion of the lower limb. However, the infant subsequently developed compartment syndrome, requiring an emergent fasciotomy. This case highlights the importance of surveillance for the development of reperfusion injury-related compartment syndrome postsystemic thrombolysis for arterial thrombosis.

Authors: Wagner Susanne 
Published: November 2019

AbstractSituated at the interface of several sub-disciplines (corpus linguistics, World Englishes, variationist sociolinguistics), this study investigates patterns of adjectival amplification (very good,so glad,pretty cool) in the Corpus of Global Web-Based English (GloWbE). It highlights regional distributions/preferences of amplifier-adjective 2-grams and the idiosyncratic status of certain bigrams according to their frequency status. Globally, clear regional preferences in amplification patterns as well as possible trends concerning change are identified. Regionally, L1 varieties contrast starkly with some regions (Africa, Indian subcontinent) but – maybe unexpectedly – not with others (Southeast Asia). The results offer insights into current trajectories of change concerning the investigated amplifiers in certain regions and 2-grams: North American varieties are leading a trend away fromverytowardssoand possiblyprettyin the future.

The optical control of phase locking of polariton condensates
Authors: Chestnov I Y , Kavokin A V , Yulin A V 
Published: November 2019

Abstract
The phase and the frequency of an exciton polariton condensate excited by a nonresonant pump can be efficiently manipulated by an external coherent light. Being tuned close to the resonance with the condensate eigenfrequency, the external laser light imposes its frequency to the condensate and locks its phase, thereby manifesting a synchronization effect. The conditions of formation of the phase synchronized regime are determined. The synchronization of a couple of closely spaced polariton condensates by a spatially uniform coherent light is examined. At the moderate strength of the coherent driving the synchronization is accompanied by the appearance of symmetry-breaking states of the polariton dyad, while these states are superseded by the symmetric state at the high-intensity driving. By employing a zero-dimensional model of coupled dissipative oscillators with both dissipative and conservative coupling, we study the bifurcation scenario of the symmetry-breaking state formation.
Simulation and assessment of the nitrogen cycle in a constant-head, one pump (CHOP) aquaponics system
Authors: Pamintuan K R S , Doma B T 
Published: November 2019

AbstractAquaponics, or the co-culture of fish and plants, has been widely regarded as a solution to the growing food requirement of an increasingly urban landscape. However, difficulties in scaling up arise particularly for start-up growers due to the lack of reliable models to describe the nutrient balance in an aquaponics set-up. In this study, a comprehensive model for the products of the nitrogen cycle is presented in a constant-head one pump (CHOP) aquaponics assembly in order to have a picture of their concentrations in the system, thereby eliminating expensive trial and error adjustments. The growth rate and rate of waste generation of Nile Tilapia,Oreochromis niloticus(Linnaeus, 1758) was mathematically represented alongside the growth rate and rate of nitrogen assimilation of lettuce (Lactuca sativa L.). The evolution of nitrifying bacteria in the biofilter was also modelled. The condition of high recirculation rates was assumed to eliminate the spatial variation of concentration in small-volume modular tanks. The results of the simulation suggest that a linear propagation of both fish and plant through time will result to a deficiency of nutrients for the plants in the beginning of the fish growing cycle, and an excess of nitrates towards the end. To manage rising nitrate levels, the adoption of a staggered growing system was suggested instead of changing water. Overall, the developed model performed satisfactorily in providing a reference to the grower, and is hoped to be extended to other nutrients as well in the future.

Published: November 2019

Abstract
This study focuses on the batch adsorption of doxycycline in simulated wastewater using Carica papaya L. (papaya) peels. Sorbate concentration (120-1,000 mg/L) and pH (3, 6, and 9) were varied while adsorbent dosage (0.1 g) and contact time (180 min) were fixed. Based on the observations done for both ripe and unripe papaya peels (PP), as the sorbate concentration increases while the pH decreases, the removal efficiency increases. The highest removal efficiency (87.97% for ripe PP and 87.52% for unripe PP) was achieved at 1,000 mg/L and pH=3. The adsorptive capacity for ripe and unripe PP was 215.09 and 213.99 mg/g adsorbent, respectively. Langmuir model fits the data for samples, which indicates a monolayer adsorption on surface of the adsorbent. The data also fits the pseudo-first order kinetic model which suggests that the reaction operates only at the monolayer of papaya peel. Overall, both ripe and unripe PP are capable of adsorbing DC in aqueous solution at 28°C, 3-hour contact time, 0.1g of adsorbent dosage, and at pH 3 under acidic condition.
Prospects for development of water resource projects in Nepal through Sino-Nepal co-operation

Published: November 2019

AbstractThe enormous amount of water resources is a boon of nature for Nepal to escalate its global status and realize the golden era of development in every possible aspect if properly utilized. However, the incompetence of Nepal in current circumstances to arrange basic requisites for harnessing its resources left the Himalayan country behind, in crisis. Meanwhile, the northern neighbouring country China has potential to render the necessary requirements through the platform of Sino Nepal co-operation which certainly yields favourable benefits for both countries and eventually transforms friendship between Kathmandu and Beijing to new horizon. This paper describes water resources of Nepal in the context of hydropower, irrigation and water supply incorporating status of Nepal and necessary technology for development. It also discusses scope, challenges and opportunities for China in Nepalese water resources, all under the platform of Sino-Nepal relationship which ultimately cultivates the co-operation.
Sustainable water provision in Tarakan City

Abstract
Clean water provision is the sixth goal of SDGs, in which all countries are struggling to achieve those goals. Indonesia is archipelagic where only 12.38% or around 2,342 islands are inhabited by a total of 17,504 islands. Clean water provision for all inhabited islands, particularly for small islands, have been a significant issue for Government of Indonesia. Availability of fresh water, ground and surface, in a small island is often critical since the island is surrounded by the sea. Hydrological process in providing annual regional fresh water is relatively stagnant. Tarakan City is an island city, located at north-east of the mainland of Kalimantan. Water provision planning is important to close the gap between the supply and demand. The latest local statistics data of population in Tarakan (2015) was 227,200 people [1] and therefore the estimated maximum demand of fresh water was 74,158,080 liters per day or 838.3 liters/second. The capacity of Local State Own Water Enterprise was only 400 liters/second, less than half of the demand. Strategies that can be taken, apart of the efforts to maximize efficient use to save water, are to minimize storm water run-offs, promote better land use planning, and strictly preserve watershed regions to have at least 30% green area.
