Surface plasmon polariton pulse shaping via two-dimensional Bragg grating pairs
Authors: Crampton Kevin T. , Joly Alan G. , El-Khoury Patrick Z. 
Published: November 2020

Abstract
We demonstrate control over the spatial and temporal properties of surface plasmon polaritons (SPPs) launched from nanohole arrays in silver. The arrays provide wave vector matching to allow the conversion of free-space photons into counter-propagating SPPs. SPPs launched from multiple arrays interfere at well-defined spatial positions, and the interference fringes form an all-SPP periodic nano-optical grating which evolves in space and time as the SPPs propagate. The spatio-temporal characteristics of the optical grating can be tuned through various nanohole array parameters such as tilt angle, separation, and array width. In addition, we examine multiperiodic arrays (MPAs) consisting of arrays with different pitches placed adjacent to one another. This platform allows the temporal interference of SPPs with different central wavelengths to be tailored through the MPA geometric and structural parameters. The temporal interference serves as an encoded signal, whereby the frequency components can be controlled by the array properties.

Published: November 2020

Abstract
Hyaluronic acid (HA) is widely distributed in the human body, and it is heavily involved in many physiological functions such as tissue hydration, wound repair, and cell migration. In recent years, HA and its derivatives have been widely used as advanced bioactive polymers for bone regeneration. Many medical products containing HA have been developed because this natural polymer has been proven to be nontoxic, noninflammatory, biodegradable, and biocompatible. Moreover, HA-based composite scaffolds have shown good potential for promoting osteogenesis and mineralization. Recently, many HA-based biomaterials have been fabricated for bone regeneration by combining with electrospinning and 3D printing technology. In this review, the polymer structures, processing, properties, and applications in bone tissue engineering are summarized. The challenges and prospects of HA polymers are also discussed.
Antioxidant metal oxide nanozymes: role in cellular redox homeostasis and therapeutics
Authors: Singh Namrata 
Published: November 2020

Abstract
Nanomaterials with enzyme-like activity, generally referred to as ‘nanozymes’, find myriad potential in various biomedical fields. More importantly, the nanoparticles that can functionally mimic the activity of cellular antioxidant enzymes attract tremendous interest owing to their possible therapeutic candidature in oxidative stress-mediated disorders. Oxidative stress culminating due to excess reactive oxygen species (ROS) level and dysregulated cellular antioxidant machinery is implicated in the development and progression of various pathophysiological disorders such as cancer, diabetes, cardiovascular and neurodegenerative diseases. Moreover, the optimum essentiality of ROS due to its pivotal role in cell signaling evokes the requirement of novel artificial antioxidant enzymes that can circumvent the detrimental effects of enhanced ROS levels without perturbing the basal redox status of cells. In recent years, the fast emanating artificial enzymes, i.e. nanozymes with antioxidant enzyme-like activity, has made tremendous progress with their broad applications in therapeutics, diagnostic medicine, bio-sensing, and immunoassay. Among various antioxidant nanoparticles reported till-date, the metal oxide nanozymes have emerged as the most efficient and successful candidates in mimicking the activity of first-line defense antioxidant enzymes, i.e. superoxide dismutase, catalase, and glutathione peroxidase. This review intends to exclusively highlight the development of representative metal oxide-based antioxidant nanozymes capable of maintaining the cellular redox homeostasis and their potential therapeutic significance.
Osservazioni su Philem. fr. 95 K.‑A. per la difesa del v. 2

Published: November 2020

AbstractThe present contribution aims to investigate, from the point of view of text and content, fr. 95 K.‑A. of the comic author Philemon. The fragment, which likely belonged to the prologue of a comedy of name unknown, is spoken by Aere (perhaps an allegory), which provides a self-presentation of traits that are para-philosophical and, specifically, Presocratic. Line 2 of the fragment has been condemned by all editors to date, but through an analysis of the fragment’s textual tradition, the line’s syntactic structure and the parodic implications, it is proposed here to retain the line. Finally, reflections are offered also on line 3, considering it in accord with the textual choices adopted in relation to the preceding line.
Thermoelastic characterization of carbon nanotube reinforced PDMS elastomer
Authors: Paul Jinu 
Published: November 2020

Abstract
Internal energy and entropy contribution to the elasticity of carbon nanotube reinforced polydimethylsiloxane (PDMS) is evaluated using statistical theory of rubber elasticity. Stress–temperature measurements were performed and the data was used to calculate the internal energy contribution to elastic stress. Interesting aspects such as increase in energy and low entropy contribution to the elasticity of carbon nanotube reinforced PDMS is observed. This can be related t o the deformation behavior of the network chains of pristine elastomers and the directional reorientation of nanotube entanglements. While the entropy change is associated with reorientation or directional preference of the carbon nanotube entanglements, the internal energy change is associated with structural bending or stretching of the nanotubes. A reversible deformation of nanotube entanglements complements rubber like elasticity and the present study gives insights into the thermoelasticity of reinforced elastomers as well as the elastic behavior of carbon nanotube entanglements inside a polymer matrix.
Technique of pressurized intrathoracic aerosol chemotherapy (PITAC) for malignant pleural effusion
Authors: Drevet Gabrielle , Maury Jean-Michel , Bakrin Naoual , Tronc François 
Published: November 2020

Abstract

Objectives
Malignant pleural effusion (MPE) is a devastating evolution of several malignancies. Pressurized intrathoracic aerosol chemotherapy (PITAC) might be a novel therapy option in MPE.

Methods
PITAC is considered for patients with MPE with a performance status <2 and without other metastatic sites. General anesthesia is administered and a double-lumen bronchial tube is inserted. The patient is placed in a lateral decubitus position, and the operation is performed after ipsilateral lung exclusion. Two 12-mm balloon trocars are inserted—one in the seventh intercostal space in the mid-axillary line and one in the fifth intercostal space in the anterior axillary line. Extent of pleural disease and volume of MPE are documented. MPE is removed and parietal pleural biopsy are performed. An intrathoracic pressure of 12 mmHg CO2 is established, and a combination of Cisplatin (10.5 mg/m2 in a total volume of 150 cc NaCl 0.9%) and Doxorubicin (2.1 mg/m2 in a total volume of 50 cc NaCl 0.9%) are aerosolized via nebulizer in the pleural cavity. Vital signs and nebulization are remote-controlled. After 30 min, the remaining toxic aerosol is exhausted using a closed surgical smoke evacuation system. A 24Fr chest tube is inserted in postero-apical position with continuous negative pressure of 20 cm H2O. When needed, PITAC may be repeated every six weeks in alternate with systemic chemotherapy.

Results
In our hands, the technique above has shown to be feasible and safe.

Conclusions
Further studies are needed to assess the potential symptomatic and oncological benefits of PITAC in MPE.
Automated synthesis of the 16α-[18F]fluoroestradiol ([18F]FES): minimization of precursor amount and resulting benefits
Authors: Fedorova Olga , Orlovskaya Viktoriya , Nadporojskii Michail , Krasikova Raisa 
Published: November 2020

Abstract
The 16α-[18F]Fluoroestradiol ([18F]FES) is an established PET radiotracer for estrogen positive (ER+) breast cancer. Although the radiosynthesis is well-described, the majority of the published methods suffer from modest or irreproducible yields and time-intensive purification procedures. In view of the considerable clinical applications, development of a more efficient and faster synthesis of [18F]FES still remains a task of a significant practical importance. [18F]FES was produced by a direct nucleophilic radiofluorination of 3-O-methoxymethyl-16,17-O-sulfuryl-16-epiestriol (MMSE), followed by acidic hydrolysis using HCl/CH3CN. [18F]Fluoride retained on a QMA carb cartridge (46 mg) was eluted by solution of 1.2 mg of tetrabutylammonium tosylate (TBAOTs) in EtOH. After fluorination reaction (0.3 mg MMSE, 1 ml of CH3CN/100 °C, 5 min) [18F]FES was isolated by single-cartridge SPE purification using OASIS WAX 3cc, elution accomplished with aqueous ethanol of different concentrations. On а GE TRACERlab FX N Pro automated module [18F]FES (formulated in normal saline with 5% EtOH) was obtained in 33 ± 3% yield (n = 5, non-decay corrected) within 32 min. Reduction of precursor amount, exclusion of azeotropic drying step and simplification of purification make the suggested method readily adaptable to various automated synthesizers and offers significant cost decrease.

AbstractIn general, the main compositions of porcelain and bone china composed of 54-65%wt silica (SiO2), 23-34% wt alumina (Al2O3) and 0.2-0.7%wt calcium oxide (CaO) suitable for preparation high quality ceramic products such as soft-hard porcelain products for teeth and bones, bioceramics, IC substrate and magneto-optoelectroceramics. The quality of ceramic hand mold is depended on raw material and its properties (pH, ionic strength, solid-liquid surface tension, particle size distribution, specific surface area, porosity, density, microstructure, weight ratio between solid and water, drying time, and firing temperatures). The suitable firing conditions for porcelain and bone china hand-mold preparation were firing at 1270°C for 10 h which resulted in superior working molds for making latex films from natural and synthetic rubber. The obtained fired porcelain hand molds at 1270°C for 10 h provided good chemical durability (10%NaOH, 5%HCl and 10%wtNaCl), low thermal expansion coefficient (5.8570 × 10−6(°C−1)), good compressive (179.40 MPa) and good flexural strength (86 MPa). While thermal expansion coefficient, compressive and flexural strength of obtained fired bone china hand molds are equal to 6.9230 × 10−6(°C−1), 128.40 and 73.70 MPa, respectively, good acid-base-salt resistance, a smooth mold surface, and easy hand mold fabrication. Both obtained porcelain and bone china hand molds are a low production cost, making them suitable for natural and synthetic rubber latex glove formation.

Authors: Padhiary Samprit , Samal Dibyaranjan , Khandayataray Pratima , Murthy Meesala Krishna 
Published: November 2020

AbstractIndia is the second country in tobacco production in the world. Smoking tobacco products included Hookah, Cohutta, Chillum, Chillum, ganja, Beedi, Mava, Cigarettes, and cigar etc. Various types of smokeless tobacco like betel quid, khaini, mishri, snuff, gutkha are used. Fifty percent of them are addicted to smokeless tobacco. Sixty eight smokeless tobacco products were available in 2010; most of them included the risk of cancer warning except for loose tobacco products. Women mostly prefer 8 out of 29 gutkha brands. Out of these 29 gutkha brands, 15 were loose tobacco packets. India is the second-largest tobacco consumer, comprises of 27.5 crore consumers which altogether greater than the population of Western Europe. From among these 27.5 crore consumers, 16.4 crore people are smokeless tobacco in takers, 6.9 crore people are exclusive smokers and 4.2 crore people are both tobacco in takers and exclusive smokers. If we take this data into consideration early mortality of 45 crore people is expected by 2050 worldwide. Female basically are prone to fewer cigarettes per day as compared to males. On the other hand, a cigarette that is consumed by females has lower nicotine content as compared to males. In developing countries, the female population has less prevalence of smoking because the level of employment is low, socio-cultural norms, and health and beauty concerns. According to the estimation by the South East Asia Region (SEAR) in the year 2000 basically from India, we encounter death of about 18% men and about 3% of women due to tobacco. Various policies have been set up to control the use of tobacco. So that threat to public health is reduced. Policies like tobacco control policy, pro-health policy are set up for this purpose. Talking about the effects on a longer-term usage of water pipe can add up to the risk of getting affected by cancers of lungs, mouth, bladders, atherosclerosis, cardiovascular and pulmonary diseases, tooth extraction, etc.

Published: November 2020

Abstract
A large literature has used patent data to measure knowledge spillovers across inventions but few papers have explicitly measured the impact of the collaboration networks formed by inventors on the quality of invention. This paper develops a method to measure the impact of collaboration networks of inventors on invention quality. We apply this methodology to the information and communication technology (ICT) and information security sectors in Israel and find that the quality of Israeli inventions are systematically linked to the structure of the collaborative network in these sectors.

Abstract
Term energies, oscillator strengths, transition probabilities, and transition wavelengths among the low-lying states of (1s2)2s22p2, 2s22p3p, 2s2p3, 2s22p3s, and 2s22p3d 1,3,5
L
L = S, P, D, F in N+, F3+, and Ne4+ ions were calculated by using the multiconfiguration Rayleigh-Ritz variation method and restricted variation method. The transition oscillator strengths and transition probabilities for the electric dipole transitions are both given in length and velocity gauges. Deviations between these two gauge values are discussed. The calculated atomic parameters are in good agreement with the observed experimental results and other theoretical data. Furthermore, the uncertainty of each electric dipole transition is estimated. Several uncertainties of transition parameters are improved when comparing with values from national institute of standards and technology NIST database. Atomic parameters presented in this paper should be useful for identifying the levels as well as for precise spectral modeling in astrophysical and laboratory plasmas in the future work.

we have reconstructed the different scalar fields and the corresponding potentials. In the case of tachyon, ΛCDM fixed point is attained under this cosmological settings. Considering k-essence in this interacting situation, we have derived some constraints on the interaction term as well as Tsallis holographic dark energy parameter. Reconstructing dilaton scalar field, we have studied the behavior of scalar field and potential. In all those cases, the reconstructed Equation of State (EoS) parameters have been plotted and when computed for current universe z = 0 are found to be consistent with various observational data including Planck + WP + BAO. The only exception is a particular case of reconstructed k-essence model where phantom behavior is apparent, but its numerical value is deviated from the bounce set by the observations. Expressions for different constraints have been obtained and evolutionary behavior of reconstructed scalar fields and potentials for the various cases have been pictorially presented. Finally, we have developed a functional relationship between Hubble parameter and redshift and optimized the parameter values through χ

Why We Learn Less from Observing Outgroups
Authors: Kang Pyungwon , Burke Christopher J. , Tobler Philippe N. , Hein Grit 
Published: November 2020

Humans are less likely to learn from individuals belonging to a different group (outgroup) than from individuals of their own group (ingroup), yet the source of this societally relevant deficit has remained unclear. Here we used neuroimaging and computational modeling to investigate how people learn from observing the actions and outcomes of ingroup and outgroup demonstrators. Politically left-wing male and female participants performed worse when observing computer-simulated actions they believed were from a right-wing outgroup member compared with those from a left-wing ingroup member. A control experiment in which participants observed choices from a nonhuman agent confirmed that this performance difference reflected an outgroup deficit, rather than an ingroup gain. Accounting for the outgroup deficit, a computational model showed that participants relied less on information from outgroup actions compared with ingroup actions, while learning from outgroup outcomes was not impaired. At the neural level, the differences in observational ingroup versus outgroup learning were reflected in lateral prefrontal activity. The stronger the activity in this region, the more strongly participants weighed ingroup compared with outgroup learning signals (action prediction errors), which formally captured deficits in outgroup learning. Together, our work provides a computational and neural account of why people learn less from observing outgroups.SIGNIFICANCE STATEMENTLearning from observing others is an efficient way to acquire knowledge. In our globalized world, “the others” often are people from a different social group (outgroup). There is evidence that people learn less from observing outgroup individuals compared with individuals from their own group (ingroup). However, the source of this outgroup deficit in observational learning remained unknown, which limits our chances to improve intergroup learning. Our results showed that participants rely less on observed outgroup actions compared with ingroup actions, while learning from outgroup outcomes is not impaired. On the neural level, this outgroup deficit was reflected in the activation of the inferior frontal gyrus. These findings imply that intergroup learning should rely on observing outcomes, rather than actions.
