Application of artificial intelligence in cancer patient care during COVID-19 pandemic
Authors: Zheng Shuhua , MENG Yue 
Published: March 2021

The SARS-CoV-2 has caused tremendous stress in cancer patient care. Millions of confirmed cases and hundreds of thousands of deaths have been reported since the virus first reported in just 6 months ago in January 2020. While patients with chronic diseases such as hypertension, diabetes mellitus (DM), and chronic obstructive pulmonary disease (COPD) are particularly vulnerable to COVID19, cancer patients will probably suffer the most from visits due to weak immune system, frequent hospital visits, complicated treatment regimens, and ever-growing costs of seeking in-person healthcare. In this perspective, we propose a simple workflow based on artificial intelligence (AI) that integrates currently available platforms and resources. The workflow hereby proposed is easy to develop and will promote the entry of the first clinical application of AI in modern medicine.
All Is Lost: The Inescapable Encounter with “the Other” in Paul Bowles’ The Sheltering Sky
Authors: Movaghati Sina 
Published: March 2021

Abstract
Emmanuel Lévinas’ philosophy of “the Other” has a resounding echo in Paul Bowles’ magnum opus The Sheltering Sky. Kit Moresby, the American heroine, who has a dehumanizing (totalizing) attitude toward the North African natives, experiences an allegorical pilgrimage from the comforting shelter of “the same” toward the unfamiliar world of “the Other.” This article offers a close-reading of the novel based on Lévinasian concepts such as “the Other” and “the Face” and attempts to show that how Kit is deprived of her worldly possessions and is compelled to desist from her totalizing attitude toward “the Other.
T. S. Eliot and the Question of the Will in The Waste Land
Authors: Alonso Leticia Pérez 
Published: March 2021

Abstract
This article examines The Waste Land in terms of Nietzsche's theory of the will to power and the eternal recurrence. The German philosopher and T. S. Eliot concurred that nihilism was the modern condition, yet they took different attitudes toward existential skepticism. For Nietzsche it was the will to power that could defeat nihilistic states, to the extent that it leads to self-improvement and the pursuit of ambitions. Individuals that exploit the potentialities of the will, known as Übermenschen, relish life on earth as part of their own creation, even if it were repeated as infinitum. This outlook disparages the Christian belief in an imaginary afterworld that compensates for earthly agony. Unlike Nietzsche, Eliot does not condemn religion, but rather the loss of spiritual values resulting in the imbalance of the will. The poet appears to argue for the Buddhist middle way that rejects extremes of self-gratification and mortification, eternalism and annhilationism. As the literary equivalent of the eternal recurrence, the allusions in The Waste Land juxtapose past moments that reveal the excess of the will with its deficiency in the present. The poem thus hints at moderation as the key to liberate humanity from cycles of suffering.
Design and Performance Research on Dual Layer Cement Based Absorber Reinforced with Graphene Nanosheets and Manganese-zinc Ferrite
Authors: SUN Yafei , ZHOU Tianshu , PENG Yueyue , LIU Hongwei 
Published: March 2021

Dual layer cement-based absorber is synthesized by mixing with graphene nanosheets and manganese-zinc ferrite, to study the effect of absorbing filler content on the mechanical properties, microstructure, electrical resistivity and reflectivity of the paste. The microstructure of the absorber is seen by Scanning Electron Microscope (SEM) images, Fourier Transform Infrared (FTIR) spectroscopy, X-Ray Diffraction (XRD) curves of the absorber. The results show that graphene nanosheets significantly reduce the electrical resistivity of paste, increasing its mechanical properties by improving its pore structure. SEM images indicate that graphene nanosheets promote the increase and coarsening of cement hydration products and produce a large number of dense bulk crystals. Furthermore, reflectivity measurements show that the minimum reflectivity of – 14.1 dB is obtained in the range of 2 ~ 18 GHz and the effective bandwidth of 16 GHz is obtained when reflectivity is less than – 7 dB. This study provides a new method for the preparation of dual layer cement-based absorber.

Published: March 2021

Dans cet article, nous proposons d’explorer l’articulation entre mémoire collective et prise en compte de l’existant dans la conduite de projets de réaménagement d’espaces publics, à travers l’analyse de la blueFACTORY (Suisse). Après avoir constaté un écart significatif entre le « patrimoine reconnu » des autorités planificatrices et le « patrimoine perçu » de ceux qui fréquentent les espace en cours de transformation, nous posons la question de la capacité des instruments régulateurs du patrimoine à intégrer tout un ensemble d’objets mis de côté et pourtant investis d’une valeur symbolique à portée patrimoniale. Nous proposons aussi une méthode susceptible d’élargir les « espaces de négociation » par lesquels se déterminent ces éléments dignes d’être conservés, protégés ou mis en valeur dans le cadre d’un projet urbain. Enfin, nous concluons sur l’opportunité de saisir la mémoire collective (lointaine ou récente) comme levier opérationnel de valorisation de l’histoire d’un lieu, ainsi que des éléments porteurs de valeur symbolique et de valeur d’usage.
POLÍTICA DE FORMAÇÃO DE PROFESSORES: A “QUALIDADE” COMO PROBLEMA
Authors: Michels Maria Helena 
Published: March 2021

A “qualidade” da/na formação do professor é um dos slogans da política educacional na América Latina. Buscando compreender tal proposição esta pesquisa analisou documentos de organismos internacionais e dos governos chileno e brasileiro. Tais encaminhamentos nos levam a compreender que a propalada “qualidade” na educação vem atrelada à ideia de estandardização, em diferentes instâncias: instituições formadoras; índice de desempenho do ingressante dos cursos de formação; desempenho do estudante no final de sua formação; sua atuação na escola. Este controle define parte desse processo que indica a chamada “epistemologia da prática” e é compreendido como um problema para a formação de professores.

Soil texture is a vital variable that reflects a number of soil properties such as Bulk Density, Particle Density, Infiltration Rate, Hydraulic conductivity, Water holding capacity, nutrient storage and availability as well as transport and binding and stability of soil aggregates. For better tuber development in cassava soil texture plays vital role. The main objective of this study is to produce kriged maps (Ordinary kriging map and semivariogram) to interpolate the soil texture for Tapioca growing soils of Paramthy block, Namakkal District at unsampled locations. In this study, nearly 54 surface samples were collected covering 19,149 ha of agriculture land with dominant cultivation of Tapioca. This study helps spatial interpolation of unsampled location of soil texture i.e. sand, silt and clay content which rules the soil physical, chemical and hydrological properties. The average standard error for sand and clay are 0.2 and 0.19 respectively. The results such as provided maps and their associated variance can be used as data source for the development and implementation of further land management and soil water conservation plans in the study area.

Published: March 2021

Aim: In this study, the antibacterial effect of the n-hexane, methanol, and ethanol extracts of two traditional medicinal plants, Nigella sativa and Moringa oleifera was carried out to comparatively assess the antibacterial efficacy of these plants against some selected multi-drug resistant diarrheagenic bacterial isolates such as Escherichia coli, Salmonella typhi, Shigella spp, Enterobacter aerogenes, Klebsiella pneumonia, and Pseudomonas aeruginosa.
Methodology: The inhibitory effects of extracts were assessed using disk diffusion method at six different concentrations i.e. 12.5 mg/ml, 25 mg/ml, 50 mg/ml, 100 mg/ml, 200 mg/ml, and 400 mg/ml. The minimum inhibitory concentrations and minimum bactericidal concentrations of the plant seed extracts were determined by the micro-broth dilution technique. Synergism and antagonism studies were similarly done to determine the combined effects of both N. sativa and M. oleifera seed oil. Further, resistant bacteria were subjected to sodium dodecyl sulphate treatment for plasmid curing and continued with the antibiotic susceptibility test.
Results: The oil extracts of N. sativa were found to be more effective than that of M. oleifera (at MIC and MCC of 50 mg/ml and 100 mg/ml respectively). It was observed that the plasmids were cured in all the E. coli isolates. Among the pathogens, E. coli was highly susceptible to both seed oils.
Conclusion: Higher antibacterial activity was observed when the extracts were used in combination, showing a strong synergistic effect against all the pathogens tested.

Materials that have a biological origin find many applications in both Biomedicine and other Sciences. However, the properties of these materials are difficult to change, since natural biosynthetic mechanisms are difficult to explain, simulate, or adjust. Thus, many materials of biological origin are isolated from natural tissues or their substitutes are produced recombinantly, and then modified in the process of experimental application.
A major shift in this paradigm is caused by the emerging field of synthetic biology, which introduces innovations in the "tool kit" of methods for tuning biomolecules and biosynthetic mechanisms. Relative to materials, this led to higher product titers due to reprogrammed natural biosynthesis and allowed the development of new materials by combining the desired domains. Here we can focus on recent applications of synthetic biology to bio-derived ribosomal and non-ribosomal polymer materials for biomedical applications. It is also interesting to describe modern methods that will affect the production and design of biomaterials in the near future. Continuous innovation at the intersection of synthetic biology and materials science promises to usher in a new era of biomaterial design and synthesis.

AbstractStructure inversion asymmetry is an inherent feature of quantum confined heterostructures with non‐equivalent interfaces. It leads to a spin splitting of the electron states and strongly affects the electronic band structure. The effect is particularly large in topological insulators because the topological surface states are extremely sensitive to the interfaces. Here, the first experimental observation and theoretical explication of this effect are reported for topological crystalline insulator quantum wells made of Pb1−xSnxSe confined by Pb1−yEuySe barriers on one side and by vacuum on the other. This provides a well defined structure asymmetry controlled by the surface condition. The electronic structure is mapped out by angle‐resolved photoemission spectroscopy and tight binding calculations, evidencing that the spin splitting decisively depends on hybridization and, thus, quantum well width. Most importantly, the topological boundary states are not only split in energy but also separated in space—unlike conventional Rashba bands that are splitted only in momentum. The splitting can be strongly enhanced to very large values by control of the surface termination due to the charge imbalance at the polar quantum well surface. The findings thus, open up a wide parameter space for tuning of such systems for device applications.

AbstractFlexible tactile sensors are garnering substantial interest for various promising applications, including artificial intelligence, prosthetics, healthcare monitoring, and human–machine interactions (HMI). However, it still remains a critical challenge in developing high‐resolution tactile sensors without involving high‐cost and complicated manufacturing processes. Herein, a flexible high‐resolution triboelectric sensing array (TSA) for self‐powered real‐time tactile sensing is developed through a facile, mask‐free, high‐efficient, and environmentally friendly laser direct writing technique. A 16 × 16 pixelated TSA with a resolution of 8 dpi based on patterned laser‐induced graphene (LIG) electrodes (7 Ω sq−1) is fabricated by the complementary intersection overlapping between upper and lower aligned semicircular electrode arrays. With the especially patterning design, the complexity of TSA and the number of data channels is reduced. Meanwhile, the TSA platform exhibits excellent durability and synchronicity and enables the achievement of real‐time visualization of multipoint touch, sliding, and tracking motion trajectory without power consumption. Furthermore, a smart wireless controlled HMI system, composed of a 9‐digital arrayed touch panel based on a LIG‐patterned triboelectric nanogenerator, is constructed to control personal electronics wirelessly. Consequently, the self‐powered TSA as a promising platform demonstrates great potential for an active real‐time tactile sensing system, wireless controlled HMI, security identification and, many others.
