A survey on pseudo-Chebyshev functions
Authors: Ricci Paolo Emilio 
Published: April 2020

In recent articles, by using as a starting point the Grandi (Rhodonea) curves, sets of irrational functions, extending to the fractional degree the 1st, 2nd, 3rd and 4th kind Chebyshev polynomials have been introduced. Therefore, the resulting mathematical objects are called pseudo-Chebyshev functions. In this survey, the results obtained in the above articles are presented in a compact way, in order to make the topic accessible to a wider audience. Applications in the fields of weighted best approximation, roots of 2 × 2 non-singular matrices and Fourier series are derived.

Pé diabético. Parte 2: Neuroartropatia de Charcot
Authors: Ferreira Ricardo Cardenuto 
Published: April 2020

ResumoA neuropatia de Charcot (NC) é uma complicação lamentável e comum de pacientes com diabetes, provavelmente resutlante de uma falta de entendimento adequado dessa condição, que leva ao diagnóstico tardio.A confusão diagnóstica com quadro infeccioso contribui para que o tratamento inicialmente indicado seja equivocado ao prescrever medicação antibiótica ou, eventualmente, drenagem cirúrgica. Não é infrequente que a drenagem inadvertida do suposto abcesso revele que na verdade seu conteúdo é formado apenas de partículas provenientes da destruição osteoarticular. A educação adequada, tanto dos pacientes diabéticos quanto dos médicos responsáveis por prestar atendimento primário a estes pacientes, é fundamental para a correta compreensão das principais características relacionadas ao desenvolvimento da NC. O ortopedista geral é quem, na maioria das vezes, recebe no pronto atendimento os pacientes que se encontram na fase aguda inicial da doença. Por esta razão, esses profissionais devem estar extremamente alertas e serem capazes de identificar os primeiros sinais que permitem diagnosticar precocemente a NC. Em tese, isto possibilitaria reduzir a morbidade desta afecção na medida em que o tratamento adequado venha a ser precocemente instituído.

Montelukast Has no Impact on the Systemic Production of TGFβ-1 in Patients with Nasal Polyposis Associated with Aspirin Intolerance
Authors: Pezato Rogério , Gregório Luciano Lobato , Pérez-Novo Claudina , Bezerra Thiago Ferreira Pinto , Kosugi Eduardo Macoto 
Published: April 2020

Abstract
Introduction Nasal polyposis is a disease characterized by a mechanical dysfunction of the nasal mucosa, closely related to the unique makeup of its extracellular matrix, which develops as the result of an anomalous tissue remodeling process.Transforming growth factor beta 1 (TGF-β1) is reduced not only in the nasal polypoid tissue, but also in the plasma of aspirin-intolerant patients. These patients exhibit an imbalance in the production of eicosanoids characterized by an increase in leukotrienes. Thus, it is important that the relationship between the production of leukotrienes and TGF-β1 be assessed.
Objective To evaluate the effects of the cysteinyl leukotriene (CysLT) receptor antagonist montelukast on the systemic production of TGF-β1 in patients with nasal polyposis, with or without concomitant aspirin intolerance.
Methods The sample comprised 48 individuals with diagnosis of nasal polyposis and 15 healthy controls for comparison of the baseline TGF-β1 levels in the peripheral blood and after treatment with CysLT receptor antagonist montelukast in the nasal-polyposis group.
Results There was no difference in the change in TGF-β1 levels after the treatment with montelukast in the subgroup of patients with polyposis and asthma (p = 0.82) and in the subgroup with polyposis, asthma, and aspirin intolerance (p = 0.51).
Conclusion we found no impact of the therapy with a leukotriene receptor blocker on the production of TGF-β1, making the antileukotriene therapy a highly questionable choice for the treatment of nasal polyposis, particularly from the standpoint of seeking to modify the remodeling process in this disease.

Published: April 2020

AbstractA cross sectional survey was under taken among 75 families using structured knowledge questionnaire and observation technique. The collected data was analysed using SPSS version 16. The study findings showed that majority (60%)of the subjects had moderate knowledge on food adulteration. Out of 75 samples tested, 2.7% chili powder samples were adulterated with artificial color and 10.7% of the common salt samples were adulterated with insoluble impurities. In tea powder 12 % were adulterated with iron fillings and 2.7% 2 were adulterated with artificial color. There was significant association of knowledge score on food adulteration with age (X2
(2) =8.627 p= (2), 2 0.013) and educational status (X2
(4) =9.876, p= 0.043) of the respondents. The study concludes that the food adulteration even though (4) low, still it is existing. However awareness of the public in relation to food adulteration should be ongoing especially to the general public with lower level of education.

The Comparative Interest Group-survey project: design, practical lessons, and data sets

Published: April 2020

AbstractThis article discusses the methodology and practice behind planning and executing the Comparative Interest Group-survey project (CIG-survey). The CIG-survey includes surveys among national populations of organized interests in 9 European countries and at the European Union level. Although surveys are a useful and reliable way to collect data on a variety of topics, there are also numerous pitfalls and challenges in surveying interest groups, especially across multiple countries. Despite the prominent use of surveys in interest group research, systematic reflections on this method are scarce and data sets are not always properly archived or openly accessible. This article elaborates upon the practical implications and reflects on the lessons learnt during from the implementation of the CIG-survey. Moreover, we highlight how the fuzzy boundaries of interest communities obfuscate sampling and that surveying interest organizations requires researchers to navigate through a specific organizational context to reach and motivate respondents. We also demonstrate how a careful survey plan can positively affect response rates and enable the creation of robust comparative data sets.
Sucrose starvation induces the degradation of proteins in trans-Golgi network and secretory vesicle cluster in tobacco BY-2 cells
Authors: Oda Yamato , Asatsuma Satoru , Nakasone Hiroaki , Matsuoka Ken 
Published: April 2020

Abstract

Endomembrane transport system begins at the endoplasmic reticulum (ER), continues to the Golgi apparatus and subsequent compartment called trans-Golgi network (TGN). We found that SUT2, a tobacco sucrose-transporter ortholog and was localized in the TGN, decreased significantly under a sucrose-starvation condition. The tobacco SNARE protein SYP41, localized in the TGN and secretory vesicle cluster (SVC), also decreased under the starvation. Similarly, the SCAMP2-RFP fusion protein, which is localized in TGN, SVC, and plasma membrane (PM), was distributed solely in the PM under the starvation. Under the same starvation condition, protein secretion was not arrested but pectin deposition to cell wall was suppressed. These data indicated that the protein composition in TGN and existence of the SVC are regulated by sugar availability. Furthermore, our findings as well as the involvement of SVC in pectin secretion suggested that synthesis and transport of pectin are regulated by the level of extracellular sugars.

Artifacts and errors in cross-spectrum phase noise measurements
Authors: Gruson Yannick , Rus Adrian , Rohde Ulrich L , Roth Alexander , Rubiola Enrico 
Published: April 2020

Abstract
This article deals with the erratic and inconsistent phase-noise spectra often seen in low-noise oscillators, whose floor is of the order of −180 dBc/Hz or less. Such oscillators are generally measured with two-channel instruments based on averaging two simultaneous and statistically independent measures. Our new method consists of inserting a dissipative attenuator between the oscillator under test and the phase-noise analyzer. The thermal noise of the attenuator introduces a controlled amount of phase noise. We compare the phase noise floor to the theoretical expectation with different values of the attenuation in small steps. The analysis reveals a negative bias (underestimation of phase noise) due to the thermal energy of the internal power splitter at the instrument input, and an uncertainty due to crosstalk between the two channels. In not-so-rare unfortunate cases, the bias results in a negative phase-noise spectrum, which is an obvious nonsense. Similar results are observed separately in three labs with instruments from the two major brands. We provide experimental evidence, full theory and suggestions to mitigate the problem, and a first attempt to assess the uncertainty. Our multiple-attenuators method provides quantitative information about the correlation phenomena inside the instrument.

We have performed ab-initio electronic structure calculations to investigate the ground state properties of Pd1−x

Te (x = 0.0–0.20) alloys. The PdTe and all of its alloys are paramagnetic metals. For low concentrations, the band structure remains almost unchanged and at higher concentrations, a strong redistribution of spectral weights is observed. The most striking feature of the band structure is that the bands around the Fermi energy remain almost unchanged. The calculated Fermi surfaces are remarkably robust against disorder, strongly three-dimensional and have no or negligible nesting. The density of states at Fermi energy increases monotonically with concentration (x). Although the contribution of Ni to the density of states at Fermi energy is increasing continuously yet, Pd and Te dominate the density of states at Fermi energy. The density of states at Fermi energy and superconducting transition temperature T

Authors: He Jiayang , Huang Yanwei , Hu Mengyun , Jiang Mengci , Qiao Yu , Li Shuang , Zeng Heping 
Published: April 2020

Abstract
A low-cost and minimal-processing-step method is demonstrated to synthesize Yb2O3-ZrO2 system by laser excitation catalyzed solid-state reaction. With 980 nm CW laser irradiating, near-resonant excitation of Yb3+ ions can obviously enhance solid state reaction. As the molar content of Yb2O3 rises from 12.5% to 50%, the lattice parameter of Yb2O3-ZrO2 ceramic increases distinctly. Among them, high crystal quality of Yb2Zr2O7 and Yb0.2Zr0.8O1.9 are synthesized at the laser power of 400 W for 10 s. Two obvious Raman peaks of Yb2Zr2O7 represent increased Raman activity. X-ray photoelectron spectroscopy (XPS) and Impedance spectroscopy demonstrate the huge amount of the oxygen vacancies in Yb0.2Zr0.8O1.9. Yb2Zr2O7 shows lowest thermal conductivity among all the ceramics studied, within the range of 0.497–0.730 W mK−1 from 25 °C to 1200 °C, which indicates a promising thermal barrier material.

Published: April 2020

Abstract
A13Zr/A356 Composite was prepared by in-situ reaction of K2ZrF6 powder and cast aluminum A356 melt at different temperatures (710 °C, 750 °C, 770 °C, 790 °C). The effect of different melting temperature on the morphology of Al3Zr particles was studied, and the sliding friction and wear properties of the composites were studied by wear test. It can be seen from the x-ray diffractometer (XRD) that the prepared composite material consists of A13Zr and ɑ-Al, and also has a small part of the aluminum-silicon eutectic phase; SEM analysis shows that the particles of in-situ reinforced phase are fine, With the increase of temperature, the morphology of A13Zr reinforced phase changed from block to needle and strip, and the particle distribution of the reinforced phase was uniform and well dispersed in the matrix at 750 °C. TEM experiments show that the reinforced phase exists at 750 °C and has a good combination with the matrix, which plays a very good role in particle reinforcement Friction and wear experiments show that the different preparation temperature results in different phase morphology. The reinforced phase particles existing on the surface of composites at 710 °C and 750 °C bear most of the friction, so the friction coefficient of the composites is larger at these preparation temperature, and the main wear modes are oxidation wear and abrasive wear. The friction coefficient of the composites prepared at 770 °C and 790 °C is small, and the wear modes are mainly delamination wear and oxidation wear. When the preparation temperature is 750 °C, the wear resistance of the composites is the best.

Abstract
To obtain the energy-saving and environment-friendly lightweight bio-based thermal insulation, polyurethane matrix was incorporated with wood fiber, bamboo fiber, rice husk and liquefied polyol at different percentages (25%, 30%, and 35%). The results revealed that the apparent density for the natural fibers reinforced thermal polyurethane insulation was between 105 kg.m−3 and 178 kg.m−3 by adding 35% of the fibers into the polyurethane matrix. The thermal conductivity of the bio-based thermal insulation ranged from 0.045 to 0.065 W.m−1K−1, the addition of the natural fibers increased mechanical strength. The prepared bio-based insulation showed great potential for building thermal insulations with particularly low thermal conductivity (less than 0.065 W.m−1K−1) and self-bearing strength.
DTF: Deep Tensor Factorization for predicting anticancer drug synergy
Authors: Sun Zexuan , Huang Shujun , Jiang Peiran , Hu Pingzhao 
Published: April 2020

Abstract

Motivation
Combination therapies have been widely used to treat cancers. However, it is cost and time consuming to experimentally screen synergistic drug pairs due to the enormous number of possible drug combinations. Thus, computational methods have become an important way to predict and prioritize synergistic drug pairs.

Results
We proposed a Deep Tensor Factorization (DTF) model, which integrated a tensor factorization method and a deep neural network (DNN), to predict drug synergy. The former extracts latent features from drug synergy information while the latter constructs a binary classifier to predict the drug synergy status. Compared to the tensor-based method, the DTF model performed better in predicting drug synergy. The area under precision-recall curve (PR AUC) was 0.58 for DTF and 0.24 for the tensor method. We also compared the DTF model with DeepSynergy and logistic regression models, and found that the DTF outperformed the logistic regression model and achieved similar performance as DeepSynergy using several performance metrics for classification task. Applying the DTF model to predict missing entries in our drug–cell-line tensor, we identified novel synergistic drug combinations for 10 cell lines from the 5 cancer types. A literature survey showed that some of these predicted drug synergies have been identified in vivo or in vitro. Thus, the DTF model could be a valuable in silico tool for prioritizing novel synergistic drug combinations.
