The clinical significance of mutation in multiple pulmonary nodules is largely limited by single gene mutation-directed analysis and lack of validation of gene expression profiles. New analytic strategy is urgently needed for comprehensive understanding of genomic data in multiple pulmonary nodules. In this study, we performed whole exome sequencing in 16 multiple lung nodules and 5 adjacent normal tissues from 4 patients with multiple pulmonary nodules and decoded the mutation information from a perspective of cellular functions and signaling pathways. Mutated genes as well as mutation patterns shared in more than two lesions were identified and characterized. We found that the number of mutations or mutated genes and the extent of protein structural changes caused by different mutations is positively correlated with the degree of malignancy. Moreover, the mutated genes in the nodules are associated with the molecular functions or signaling pathways related to cell proliferation and survival. We showed a developing pattern of quantity (the number of mutations/mutated genes) and quality (the extent of protein structural changes) in multiple pulmonary nodules. The mutation and mutated genes in multiple pulmonary nodules are associated with cell proliferation and survival related signaling pathways. This study provides a new perspective for comprehension of genomic mutational data and might shed new light on deciphering molecular evolution of early stage lung adenocarcinoma.

Published: February 2021

Purpose

The tumor microenvironment (TME) plays a critical role in the pathogenesis of hepatocellular carcinoma (HCC). However, underlying compositions and functions that drive the establishment and maintenance of the TME classifications are less-well understood.

Methods

A total of 766 HCC patients from three public cohorts were clustered into four immune-related subclasses based on 13 TME signatures (11 immune-related cells and 2 immune-related pathways) calculated by MCP-counter. After analyzing the landscapes of functional annotation, methylation, somatic mutation, and clinical characteristics, we built a TME-based Support Vector Machine of 365 patients (discovery phase) and 401 patients (validation phase). We applied this SVM model on another two independent cohorts of patients who received sorafenib/pembrolizumab treatment.

Results

About 33% of patients displayed an immune desert pattern. The other subclasses were different in abundance of tumor infiltrating cells. The Immunogenic subclass (17%) associated with the best prognosis presented a massive T cell infiltration and an activation of immune checkpoint pathway. The 13 TME signatures showed a good potential to predict the TME classification (average AUC = 88%). Molecular characteristics of immunohistochemistry from Zhejiang cohort supported our SVM classification. The optimum response to pembrolizumab (78%) and sorafenib (81%) was observed in patients belonging to the Immunogenic subclass.

Conclusions

The HCC patients from distinct immune subclass showed significant differences in clinical prognosis and response to personalized treatment. Based on tumor transcriptome data, our workflow can help to predict the clinical outcomes and to find appropriate treatment strategies for HCC patients.

Authors: Yang Xintian , Wang Han , Dong Bingzi , Hu Bin , Hao Xiwei , Chen Xin , Zhao Jing , Dong Qian , Zhu Chengzhan
Published: February 2021

Background: Standard liver volume (SLV) is important in risk assessment for major hepatectomy. We aimed to investigate the growth patterns of normal liver volume with age and body weight (BW) and summarize formulae for calculating SLV in children.

Methods: Overall, 792 Chinese children (<18 years of age) with normal liver were enrolled. Liver volumes were measured using computed tomography. Correlations between liver volume and BW, body height (BH), and body surface area (BSA) were analyzed. New SLV formulae were selected from different regression models; they were assessed by multicentral validations and were compared.

Results: The growth patterns of liver volume with age (1 day−18 years) and BW (2–78 kg) were summarized. The volume grows from a median of 139 ml (111.5–153.6 in newborn) to 1180.5 ml (1043–1303.1 at 16–18 years). Liver volume was significantly correlated with BW (r = 0.95, P < 0.001), BH (r = 0.92, P < 0.001), and BSA (r = 0.96, P < 0.001). The effect of sex on liver volume increases with BW, and BW of 20 kg was identified as the optimal cutoff value. The recommended SLV formulae were BW≤20 kg: SLV = 707.12 × BSA1.09; BW>20 kg, males: SLV = 691.90 × BSA1.06; females: SLV = 663.19 × BSA1.04.

Conclusions: We summarized the growth patterns of liver volume and provided formulae predicting SLV in Chinese children, which is useful in assessing the safety of major hepatectomies.
Ion Acoustic Peregrine Soliton Under Enhanced Dissipation
Authors: Pathak Pallabi
Published: February 2021

The effect of enhanced Landau damping on the evolution of ion acoustic Peregrine soliton in multicomponent plasma with negative ions has been investigated. The experiment is performed in a multidipole double plasma device. To enhance the ion Landau damping, the temperature of the ions is increased by applying a continuous sinusoidal signal of frequency close to the ion plasma frequency ∼1 MHz to the separation grid. The spatial damping rate of the ion acoustic wave is measured by interferometry. The damping rate of ion acoustic wave increases with the increase in voltage of the applied signal. At a higher damping rate, the Peregrine soliton ceases to show its characteristics leaving behind a continuous envelope.

Published: February 2021

Radiation hardness is in the focus of the development of particle tracking and photon imaging detector installations. Semiconductor detectors, widely used in particle physics experiments, have turned into capacitive-coupled (AC-coupled) detectors from the originally developed conductively coupled (DC-coupled) detectors. This is due to the superior isolation of radiation-induced leakage current in AC-coupled detectors. However, some modern detector systems, such as the tracking detectors in the CERN LHC CMS or ATLAS experiments, are still DC-coupled. This originates from the difficulty of implementing AC coupling on very small pixel detector areas. In this report, we describe our advances in the detector processing technology. The first topic is the applications of the atomic layer deposition processing technology, which enables the very high densities of capacitance and resistance that are needed when the dimensions of the physical segmentation of pixel detectors need to be scaled down. The second topic is the flip-chip/bump-bonding interconnection technology, which is necessary in order to manufacture pixel detector modules on a large scale with a more than 99% yield of noise-free and faultless pixels and detector channels.
Assessing Children’s Executive Function: BADS-C Validity
Authors: Fish Jessica , Wilson F. Colin
Published: February 2021

Objectives

To investigate the external and ecological validity of a standardized test of children’s executive functioning (EF), the Behavioral Assessment of the Dysexecutive Syndrome for Children (BADS-C).

Background

There are few standardized measures for assessing executive functions in children, and the evidence for the validity of most measures is currently limited.

Method

A normative sample of 256 children and adolescents from age 8–16 years completed the BADS-C, and a parent or teacher completed rating scales of the child’s everyday problems related to EF (Children’s version of the Dysexecutive Questionnaire; DEX-C) and Strengths and Difficulties Questionnaire (SDQ), a commonly used measure of emotional, social, cognitive, and behavioral problems.

Results

Exploratory factor analyses yielded a two-factor structure to the BADS-C, indicative of monitoring and abstract reasoning processes, and a three-factor structure to the DEX-C, reflecting behavioral, and cognitive components of the dysexecutive syndrome as well as emotional responsiveness. Regression analyses showed significant relationships between BADS-C scores and everyday functioning as reported on the DEX and SDQ. Furthermore, there were significant differences in BADS-C scores between those children in the upper and lower quartiles on the SDQ.

Conclusion

Results provide tentative evidence of BADS-C and DEX-C construct, convergent and predictive validity.

Authors: O'Donovan Róisín , De Brún Aoife , McAuliffe Eilish
Published: February 2021

Healthcare professionals who feel psychologically safe believe it is safe to take interpersonal risks such as voicing concerns, asking questions and giving feedback. Psychological safety is a complex phenomenon which is influenced by organizational, team and individual level factors. However, it has primarily been assessed as a team-level phenomenon. This study focused on understanding healthcare professionals' individual experiences of psychological safety. We aim to gain a fuller understanding of the influence team leaders, interpersonal relationships and individual characteristics have on individuals' psychological safety and their decisions to engage in voice or silence behavior. Thirty-four interviews were conducted with healthcare professionals from across five teams working within an acute, suburban hospital. Hybrid inductive-deductive thematic analysis focused on identifying themes which captured the complexities of individuals' varied experiences of psychological safety. The themes identified were: “Personal Characteristics,” “Past Experiences,” “Individual Perceptions of Being Valued,” and “Judged Appropriateness of Issues/Concerns.” These themes are explored within the context of motivating and inhibiting factors associated with the influence of leadership, interpersonal relationships and individual characteristics on experiences of psychological safety and voice behavior. These results extend existing theoretical frameworks guiding our understanding of psychological safety by accounting for the variation in individuals' experiences and studying these significant influences on voice behavior. Important considerations for the development of interventions to enhance psychological safety are discussed.

Edible insects have gained popularity as alternative food resources in the face of climate change and increasing carbon and environmental footprints associated with conventional agricultural production. Among the positive attributes that make edible insects suitable as food and feed substrates include rapid reproduction, high energy conversion efficiency, wide distribution, diversity, reduced greenhouses gases and ammonia emissions, possibility to reduce waste and high nutritional composition. In Sub-Saharan Africa, considerable scientific data exist on use of insects as food and livestock feed. However, coherent policies regarding safety, sustainability, trade and regulation of insects as food and animal feed are lacking. The benefits associated with edible insects are likely to accrue in Sub-Saharan Africa through use of a combination of approaches such as ensured sustainable utilization of edible insects in the wild, preservation of traditional conservation, harvesting and consumption practices, development of captive mass production schemes and strengthening robust value chains to incentivise indigenous participants. Collectively these approaches are referred to as the steward and use of insects as food and animal feed. This paper examines the policy frameworks that exist to support the use of edible insects as food and feed on the African continent. This investigation employed a literature review focussing on national policies in selected African countries to assess the relevance to edible insects. Using a baseline of more than 10 edible insect species consumed, 10 country cases in Sub-Saharan Africa were used to support our in-depth examination of the policy situation that may support good stewardship of edible insects as food and feed. Focus on how policies encompassing biodiversity, natural resources, culture, education, research, technology development, trade, health and nutrition and how that could be improved to support inclusivity of edible insects is discussed. We conclude by proposing a pathway that may accelerate recognition and valorisation of edible insects as important food and feed resources in Sub-Saharan Africa including improving policies to support good stewardship of these resources for sustainability.

Published: February 2021

We studied the sequential pathology of peste des petits ruminants (PPR) in Black Bengal goats and analyzed virus distribution in tissues and virus shedding following experimental infection with a Bangladeshi isolate of lineage IV PPR virus (PPRV). The early clinical signs like fever, depression, and ocular and nasal discharges first appeared at 4–7 days post-infection (dpi). Three out of eight inoculated goats died at 13, 15, and 18 dpi, and the rest were killed at different time points from 5 to 18 dpi. Initially, the virus multiplied mostly in the lymphoid organs of the pharyngeal region and caused extensive lymphoid destruction and hemorrhages. This was followed by viremia, massive virus replication in the lungs, and pneumonia along with the appearance of the clinical signs. Subsequently, the virus spread to other organs causing necrotic and hemorrhagic lesions, as well as the virus localized in the upper respiratory, oral and intestinal mucosa resulting in catarrhal, erosive, and ulcerative lesions. On hematological and biochemical investigation progressive leukopenia and hypoproteinemia, a gradual increase of serum metabolites and enzymes associated with liver and kidney damage, and electrolyte imbalance were observed. Seroconversion started at 7 dpi and all the surviving animals had serum antibodies at 14 dpi. Virus shedding was observed in nasal and ocular secretions at 4 dpi and in feces and urine at 14 dpi, which gradually increased and continued till the end of the experiment (18 dpi) despite seroconversion. Therefore, the virus shedding of naturally infected seroconverted goats should be monitored for effective control strategies.

Published: February 2021

Pythium insidiosumis a widespread pathogen that causes pythiosis in mammals. Recent increase in cases reported in North America indicates a need to better understand the distribution and persistence of the pathogen in the environment. In this study, we reconstructed the distribution ofP. insidiosumin the Chincoteague National Wildlife Refuge, located on Assateague Island, Virginia, and based on 136 environmental water samples collected between June and September of 2019. The Refuge hosts two grazing areas for horses, also known as the Chincoteague Ponies. In the past 3 years, 12 horses have succumbed to infection byP. insidiosum. Using an ecological niche model framework, we estimated and mapped suitable areas forP. insidiosumthroughout the Refuge. We foundP. insidiosumthroughout much of the study area. Our results showed significant monthly variation in the predicted suitability, where the most influential environmental predictors were land-surface water and temperature. We found that June, July, and August were the months with the highest suitability forP. insidiosumacross the Refuge, while December through March were less favorable months. Likewise, significant differences in suitability were observed between the two grazing areas. The suitability map provided here could also be used to make management decisions, such as monitoring horses for lesions during high risk months.

Published: February 2021

A Educação Ambiental (EA) resulta da preocupação com os impactos negativos das ações humanas sobre o ambiente e da necessidade de formar cidadãos ambientalmente mais conscientes. O estudo objetivou conhecer a percepção dos professores de ciências e geografia em relação à EA e como esta vem sendo trabalhada com estudantes dos anos finais do Ensino Fundamental de escolas públicas da região central do Rio Grande do Sul. Foi enviado um convite por e-mail aos professores para a participação na pesquisa contendo o detalhamento dos objetivos da entrevista e o Termo de Consentimento Livre e Esclarecido (TCLE). Mediante confirmação de aceite do TCLE, foi liberado o questionário virtual. Este foi respondido por 10 professores de oito escolas. Constatou-se que a EA é trabalhada de forma superficial e disciplinar, não atendendo a Política Nacional de Educação Ambiental (PNEA). Os professores carecem de uma formação adequada para a prática em EA, pois não possuem um conceito claro do seu significado. As ações adotadas são isoladas, não voltadas para a realidade local e insuficientes para a promoção da mudança nos hábitos dos estudantes. São necessárias ações que promovam mudanças na concepção de EA para que esta seja efetiva na sua prática.

Graphene-Based Coronal Hybrids for Enhanced Energy Storage
Authors: Sarigamala Karthik Kiran , Shukla Shobha , Struck Alexander , Saxena Sumit
Published: February 2021

Functional materials with designer morphologies are anticipated to be the next generation materials for energy storage applications. In this manuscript, we have developed a holistic approach to enhance the surface area and hence the properties of nanostructures by synthesizing coronal nanohybrids of graphene. These nanohybrids provide distinctive advantages in terms of performance and stability over vertically stacked nanocomposites reported in literature. Various double hydroxide materials self-assembled as coronal lamellae on graphene shells have been synthesized and systematically studied. These coronal nanohybrids result in about a threefold increase in energy storage capacity as compared to their traditionally synthesized nanocomposite counterparts. The 3D graphene-based nanofibrils in the synthesized coronal nanohybrids provide mechanical support and connect the nodes of the double hydroxide lattices to inhibit restacking. Complex morphologies such as coronal nanostructures increase the interaction surface of the nanostructure significantly. Such an approach is also expected to bring a paradigm shift in development of functional materials for various applications such as sensors, energy storage, and catalysis.

Published: February 2021

Electronic skin (e-skin) with skin-like flexibility and tactile sensation will promote the great advancements in the fields of wearable equipment. Thus, the multifunction and high robustness are two important requirements for sensing capability of the e-skin. Here, a fully organic self-powered e-skin (FOSE-skin) based on the triboelectric nanogenerator (TENG) is developed. FOSE-skin based on TENG can be fully self-healed within 10 hours after being sheared by employing the self-healing polymer as a triboelectric layer and ionic liquid with the temperature sensitivity as an electrode. FOSE-skin based on TENG has the multifunctional and highly robust sensing capability and can sense the pressure and temperature simultaneously. The sensing capability of the FOSE-skin based on TENG can be highly robust with no changes after self-healing. FOSE-skin based on TENG can be employed to detect the arm swing, the temperature change of flowing water, and the motion trajectory. This work provides a new idea for solving the issues of monofunctional and low robust sensing capability for FOSE-skin based on TENG, which can further promote the application of wearable electronics in soft robotics and bionic prosthetics.
Open Science and Single-Case Design Research

Published: February 2021

Research indicating many study results do not replicate has raised questions about the credibility of science and prompted concerns about a potential reproducibility crisis. Moreover, most published research is not freely accessible, which limits the potential impact of science. Open science, which aims to make the research process more open and reproducible, has been proposed as one approach to increase the credibility and impact of scientific research. Although relatively little attention has been paid to open science in relation to single-case design, we propose that open-science practices can be applied to enhance the credibility and impact of single-case design research. In this paper, we discuss how open-science practices align with other recent developments in single-case design research, describe four prominent open-science practices (i.e., preregistration, registered reports, data and materials sharing, and open access), and discuss potential benefits and limitations of each practice for single-case design.

Agriculture is one of the largest sectors of the domestic economy. However, along with the economic significance of agriculture, its social significance plays an important role. Rural settlements lag significantly behind cities in the development of social infrastructure and people’s life quality. A narrow-sectoral agrarian approach, including in areas with limited agricultural potential, has led to a one-sided agrarian development in rural areas and often an irrational distribution of productive forces on them, as well as underdeveloped social infrastructure and other serious problems. The authors propose to adhere to two main approaches in the development of rural areas: forming socio-cultural objects around the core of the cluster, or preservation of each settlement. The social component is analyzed by assessing the quality of life, which takes into account the following groups of indicators: socio-demographic (life expectancy, morbidity, fertility, mortality); economic activity of the population (level of unemployment, migration); social tension (dynamics of crime, the share of the shadow economy in GDP, participation in strikes and political actions); the level of development of the social sphere (the share of spending on education, science, health care, culture in GDP, the number of schoolchildren and students, and others); environmental (the content of harmful substances in the atmosphere, soil, water, food, environmental costs in GDP, contribution to environmental protection, rational use of natural resources); minimum wage, living wage, provision of the population with social infrastructure facilities. We concluded that the gross regional product does not have a strong influence on the size of the social component, and social expenses that determine the quality of life are distributed, most likely, without taking into account the growth of GRP. The data on the social infrastructure facilities provision can be used to substantiate minimum social standards with priority state support for the development of rural settlements provided with jobs.

Due to the fact that this area has been little studied, at the moment there is no single methodology that would include those economic indicators that allow for a specific interpretation of the results obtained during the analysis. The article describes a more accessible methodology for evaluating the attractiveness of an agricultural area for investment based on labor productivity in the field of material production. In the studies written by the authors of this article, the main economic indicators for assessing the attractiveness to investment of agricultural regions of the region (Orenburg region) are presented and considered in detail. The main factors influencing the labor productivity of the labor collective are highlighted. On the basis of factor analysis, the tasks of combining a large number of indicators, signs that determine labor productivity in the agricultural production of the region, into a smaller number of factors artificially built on their basis, ensuring the resulting system of factors, are solved. This technique is more convenient from the point of view of meaningful interpretation. The original methodology clearly defines a specific agricultural area, which at the moment (or in the near future) is the most favorable for investors. To assess the investment attractiveness of individual economic systems, a theoretical and methodological toolkit has been created that allows investors to assess the share of the risk of non-return of financial resources.

To assess the performance of economic systems, criteria and performance indicators are used that show the degree of achievement of the desired performance result. To characterize complex systems in most real cases, one criterion is not enough. Therefore, several criteria are used to comprehensively characterize the system. The multi-criteria problem raises the problem of matching individual criteria when used together. There are many ways to select alternatives in the face of multiple decision criteria. This article discusses the multi-criteria comparison of objects with Pareto dominance, vector estimates with arbitrary non-negative coordinates of vectors. The advantages of vector estimates in comparison with average estimates are considered. In this work, three important theorems of multi-criteria estimation are proved. The theorems define the conditions for the equivalence of three options for comparing objects by a variety of attributes: 1) arithmetic mean values; 2) the lengths of the corresponding vectors; 3) scalar products of vectors. As the research results, the application of the developed methods for aggregating the quality indicators of the educational process into a single assessment is shown. The following indicators of the educational process were used: coefficient of diligence, coefficient of interest, coefficient of difficulty of mastering the studied material, assessment of academic performance. A four-criteria optimization problem is formulated. It is shown that the objective function reaches its extreme value at the point that is as close as possible to the point of the optimal solution of the formulated problem. The issues of multi-criteria assessment developed in the article can find application in the management of the educational process in the formation of individual trajectories of trainees, in the tasks of working with the personnel of firms and organizations (selection, training, retraining), in assessing the quality of products and in other areas of activity.
ECONOMIC IMPACT OF CORPORATE SOCIAL RESPONSIBILITY IN ENTREPRENEURSHIP

The article examines the economic impact of the costs associated with corporate social responsibility (CSR). The author has developed a formula that determines the growth rate of operating profit when CSR costs appear in order to preserve the source of investment and pay dividends. When implementing CSR activities with significant costs for one enterprise, it is proposed to allocate costs between stakeholders in the implementation of joint CSR. This makes it possible to take into account the individual possibility of each participant in a joint CSR to receive the necessary operating profit to preserve the source of investment and pay dividends when implementing joint CSR. The article also proposes an algorithm for distributing the costs of joint CSR among the participants (commercial legal entities) in order to determine the level of costs of joint CSR and the ability of the participants to cover these costs. The algorithm for distributing the joint CSR costs between the participants can be repeated several times to obtain equality between the costs of CSR and the amount of costs that the participants of the joint CSR can cover. Enterprises participating in network interaction (cluster) can carry out joint CSR based on the distribution of costs among themselves. Thus, it becomes possible to jointly conduct not only commercial activities, but also the implementation of common measures for corporate social responsibility. The distribution of the joint CSR costs among the cluster members will make it possible to carry out activities, the costs of which one company cannot cover through its operating activities.
