FEASIBILITY EXPLORATION OF “MULTI-CONFORMITY” UNDER THE BACKGROUND OF BIG DATA
Authors: Lei Y. , Wang L. H. , Wang Z. H.
Published: February 2020

Abstract. “Multi-conformity” requires the unification of surveying and mapping coordinate system. The Ministry of Natural Resources calls for the unified use of CGCS2000 coordinates in natural resources systems. Therefore, “multi-conformity” can only be carried out in the CGCS2000 coordinate system. In Bijie Experimental Area, the projection deformation of CGCS2000 coordinate system is far greater than the requirement of 2.5cm/km stipulated in the urban surveying, so it can not be directly used in urban construction, and its own independent coordinate system must be established. In order to resolve this contradiction and meet the requirements of “multi-conformity”, Ministry of Natural Resources and urban construction, to explore the transformation of geographic information data under CGCS2000 coordinate system into urban independent coordinate system data in time by using the cloud computing function of big data under the condition of unification of basic data to meet the needs of engineering construction and to serve the economic construction of Bijie Experimental Area.
A mobile nondestructive testing (NDT) system for fast detection of impact damage in fiber-reinforced plastics (FRP)
Authors: Rittmann Johannes , Rahammer Markus , Holtmann Niels , Kreutzbruck Marc
Published: February 2020

Abstract. Impact damage in fiber-reinforced plastics, such as carbon-fiber-reinforced plastics (CFRP) and glass-fiber-reinforced plastics (GFRP), involves high challenges to nondestructive testing (NDT). The anisotropic material structure significantly complicates the interpretation of results in conventional testing. Resonant frequency sweep thermography (RFST) based on local defect resonance combined with well-known ultrasonic thermography enables the fast and simple detection of relevant impact damages. RFST utilizes frequency sweep excitation in the low- and mid-kilohertz range to activate defect resonances with low acoustical power of a few megawatts. Resonances of defects amplify the acoustic vibration amplitude by more than 1 order of magnitude and lead to a significant enhancement of the corresponding thermal signal. This is based on both crack friction and/or visco-elastic heating and can be detected at the part surface by an infrared camera. The defect detection threshold depends on excitation power and the distance between the defect and the ultrasonic source. For this new NDT approach, a first prototype system in the form of a tripod
with an integrated infrared (IR) camera and ultrasonic excitation was developed. It
stands out due to its simple handling and flexible applications. Augmented
reality assists the inspector to interpret the results and mark the defect by
projecting the evaluated test result onto the part surface. In this article, the first results from a series of impact damages in CFRP of varying impact energies and crack sizes are presented.
Anthropocene Climate Bifurcation
Authors: Kypke Kolja Leon , Langford William Finlay , Willms Allan Richard
Published: February 2020

Abstract. This article presents the results of a bifurcation analysis of a simple Energy Balance Model (EBM) for the future climate of the Earth. The main focus is on the question: Can the nonlinear processes intrinsic to atmospheric physics, including natural positive feedback mechanisms, cause a mathematical bifurcation of the climate state, as a consequence of continued anthropogenic forcing by rising greenhouse gas emissions? Our analysis shows that such a bifurcation could cause an abrupt change, to a drastically different climate state in the EBM, warmer and more equable than any climate existing on Earth since the Pliocene Epoch. In previous papers, with this EBM adapted to paleoclimate conditions, it was shown to exhibit saddlenode and cusp bifurcations. The EBM was validated by the agreement of its predicted bifurcations with the abrupt climate changes that are known to have occurred in the paleoclimate record, in the Antarctic at the Eocene-Oligocene Transition (EOT) and in the Arctic at the Pliocene-Paleocene Transition (PPT). In this paper, the EBM is adapted to fit Anthropocene climate conditions, with emphasis on the Arctic and Antarctic climates. The four Representative Concentration Pathways (RCP) developed by the IPCC are used to model future CO2 concentrations, corresponding to different scenarios of anthropogenic activity. In addition, the EBM investigates four naturally occurring nonlinear feedback processes which magnify the warming that would be caused by anthropogenic CO2 emissions alone. These four feedback mechanisms are: ice-albedo feedback, water vapour feedback, ocean heat transport feedback and atmospheric heat transport feedback. The EBM predicts that a bifurcation resulting in a catastrophic climate change will occur in coming centuries, for an RPC with unabated anthropogenic forcing, amplified by these positive feedbacks. However, the EBM suggests that appropriate reductions in carbon emissions may limit climate change to a more tolerable continuation of what is observed today. This EBM has an Equilibrium Climate Sensitivity (ECS) near the high end of the range recorded by the IPCC.
Diagnosing the sensitivity of grounding line flux to changes in sub-ice shelf melting
Authors: Zhang Tong , Price Stephen F. , Hoffman Matthew J. , Perego Mauro , Asay-Davis Xylar
Published: February 2020

Abstract. We seek to understand causal connections between changes in sub-ice shelf melting, ice shelf buttressing, and grounding-line flux. Using a numerical ice flow model, we study changes in ice shelf buttressing and grounding line flux due to localized ice thickness perturbations – a proxy for changes in sub-ice shelf melting – applied to idealized (MISMIP+) and realistic (Larsen C) domains. From our experiments, we identify a correlation between a locally derived buttressing number on the ice shelf, based on the first principal stress, and changes in the integrated grounding line flux. The origin of this correlation, however, remains elusive from a physical perspective; while local thickness perturbations on the ice shelf (thinning) generally correspond to local increases in buttressing, their integrated impact on changes at the grounding line are exactly the opposite (buttressing at the grounding line decreases and ice flux at the grounding line increases). This and additional complications encountered when examining realistic domains motivates us to seek an alternative approach, an adjoint-based method for calculating the sensitivity of the integrated grounding line flux to local changes in ice shelf geometry. We show that the adjoint-based sensitivity is identical to that deduced from pointwise, diagnostic model perturbation experiments. Based on its much wider applicability and the significant computational savings, we propose that the adjoint-based method is ideally suited for assessing grounding line flux sensitivity to changes in sub-ice shelf melting.
Controls-Oriented Model for Secondary Effects of Wake Steering
Authors: King Jennifer , Fleming Paul , King Ryan , Martínez-Tossas Luis A. , Bay Christopher J. , Mudafort Rafael , Simley Eric
Published: February 2020

Abstract. This paper presents a model to incorporate the secondary effects of wake steering in large arrays of turbines. Previous models have focused on the aerodynamic interaction of wake steering between two turbines. The model proposed in this paper builds on these models to include yaw-induced wake recovery and secondary steering seen in large arrays of turbines when wake steering is performed. Turbines operating in yaw misaligned conditions generate counter-rotating vortices that entrain momentum and contribute to the deformation and deflection of the wake at downstream turbines. Rows of turbines can compound the effects of wake steering that benefit turbines far downstream. This model quantifies these effects and demonstrates that wake steering has greater potential to increase the performance of a wind farm due to these counter-rotating vortices especially for large rows of turbines. This is validated using numerous large eddy simulations for two-turbine, three-turbine, five-turbine, and wind farm scenarios.
'Jalal's Law': Driving Reform in the Wrong Direction
Authors: Freiberg Arie
Published: February 2020

This article provides a case study of the process of criminalising a form of dangerous driving in Victoria. It examines the process whereby an ostensibly draconian Bill was transformed into one far less damaging to fundamental criminal law principles and illustrates how populism may be tempered by proper parliamentary procedures, cooperation between parties and a desire to balance political and legal imperatives. It also examines the place of constructive offences in the criminal law and the role that the consequences of an offence plays in the structure of the substantive criminal law and in sentencing, particularly in the context of driving offences.
Controlled-Release Fertilizer in the Production of Seedlings of Anonna cacans Warm
Authors: Smiderle Oscar José , Souza Aline Das Graças , Menegatti Renata Diane
Published: February 2020

The use of controlled-release fertilizers is a promising alternative for supplying nutrients during the initial growth of nursery seedlings. The aim of this study was to verify the effects of different doses of controlled-release fertilizer (CRF) on initial growth and nutritional status in seedlings of Anonna cacans Warm. The seeds were originally sown in a seedbed and then, after initial seedling development, were transplanted into polyethylene bags containing a substrate of washed medium sand, to which different doses of CRF had been added before transplanting. The experimental design was completely randomised, with four treatments, five doses of Osmocote® NPK 19-06-10 formulation (0, 1, 2, 4 and 8 g L-1 of substrate), with four replications, each replication comprising three seedlings (one in each container). Increases in root-collar diameter and plant height were determined throughout the experimental period (6 months) from data collected every 30 days after transplanting. At the end of the experiment the following were evaluated: height, root-collar diameter, N concentration, chlorophyll index, chlorophyll concentration (a, b and total) and leaf area. Root-collar diameter and height showed a positive linear response to increases in the fertilizer dose. From a 4 g L-1 dose of CRF, the nutrient supply added to the substrate of medium sand optimises the initial phase of plant growth and guarantees the adequate nutritional status of Anonna cacans, and can be suggested as a viable technique for use in forest nurseries, and one which results in efficient use of the input material and avoids fertilizer wastage.
Theory and Philosophy: Antonyms in Our Semantic Field?
Authors: Jay Martin
Published: February 2020

Building on the argument of a 1996 piece called “For Theory,” which situated “theory” in a force field of its putative opposite terms, this essay explores the way “philosophy” has come to be considered an antonym of “theory” in much contemporary discourse. It argues that despite their often contrasting meanings and connotations, the two terms would benefit from a dialogue in which the strengths of each were acknowledged without their being either hierarchically positioned or turned into bland synonyms.
The Body as a Site of Material-Symbolic Struggle: Toward a Marxist New Materialism
Authors: Chaput Catherine
Published: February 2020

This essay explores how a physiological notion of affect, one predicated on the transsubstantial circulation of micro-materiality, provides useful connectivity among old and new materialisms. First, it explores nascent theories of energetic matter in Marxism as potential sites for new materialist extensions. Second, it proposes affect as a theoretical shorthand for the circulating flows of matter central to the physiological production, orientation, and materialization of bodily capacities, including the ability to reinvent political economic habituation from the perspective of difference. Third, it illustrates the contributions of a Marxist new materialism through a brief discussion of contemporary race politics.
Perianal abscess and fistula-in-ano in children – evaluation of treatment’s efficacy. Are we able to avoid the recurrence?
Authors: Bałaż Katarzyna , Trypens Agata , Polnik Dariusz , Pankowska-Woźniak Katarzyna , Kaliciński Piotr
Published: February 2020

AIM
Perianal abscess and fistula-in-ano are common findings in infants and children. The perianal abscess is usually a manifestation of the fistula-in-ano. Experience of our center indicates a general lack of knowledge of the abscess’s origin therefore it is usually treated by incision and drainage which leads to numerous recurrence. We aimed to present the optimal management of the fistula-in-ano and perianal abscess to lower or even eliminate recurrences.

METHOD
The retrospective study consisted of 24 infants treated in our center with perianal abscess from 2013 to 2015. The patients were divided into two groups: group I (50%) was primary treated in our center, group II had prior surgical interventions in other hospitals. Fistula-in-ano was intraoperatively identified in all patients (100%) and fistulotomy was performed.

RESULTS
No recurrence of the perianal abscess or fetal incontinence were observed in any patient. In the group II, the ailment was associated with severe inflammation, some patients underwent an additional surgical intervention such as incision and drainage of the extensive buttock’s abscess; the patients required longer antibiotic therapy and longer hospitalization.

CONCLUSION
Low-invasive approach (hip-bath, antibiotic therapy, puncture or incision and drainage of the abscess) seems to be tempting due to its simplicity and no need of general anesthesia but it is associated with high recurrence rate. Fistulotomy and fistulectomy, which are slightly more invasive procedures, significantly lower the recurrence rate of fistula-in-ano and perianal abscess.
The Interface between Interactive Art and Human-Computer Interaction: Exploring Dialogue Genres and Evaluative Practices
Authors: Felipe Duarte Emanuel , Merkle Luiz Ernesto , Baranauskas M. Cecília C.
Published: February 2020

The mutual efforts of joining art and science have been an important source of innovation in many fields throughout history. In this article, we investigate the relatively common origins, differences, and similarities between the Interactive Art and Human-Computer Interaction (HCI) areas of knowledge. We also investigate what kind of human-computer interactions are sought by artists or emerge in Interactive Art examples, as well as what kind of frameworks, evaluation criteria or methodologies are reported in the literature to support the design and evaluation of Interactive Art. As a result of our analysis of Interactive Art examples found in the literature and beyond, we derived four genres of dialogue that emerge naturally or are stressed by authors: visual, embodied, tangible and social. These genres, albeit not comprehensive, can inspire the design of novel forms of interaction in computational systems with or without artistic intent. Moreover, frameworks, evaluation criteria, and methodologies may allow a cross-pollination between Interactive Art and HCI. While interactive artists may provide novel ways to look at the design and evaluation of interactive systems, these artists may also benefit from appropriating traditional HCI methods, tools, and technologies for new purposes. Lastly, we draw on our findings and learned lessons to outline a research agenda with the main objectives of 1) encouraging Interactive Art research, 2) studying Interactive Art examples, 3) practicing Interactive Art design and evaluation, and 4) designing Interactive Art for all.
Defining Inspection Techniques for Detecting Privacy Problems in Online Social Networks
Authors: Rodrigues Andrey , Valentim Natasha M. C. , Feitosa Eduardo
Published: February 2020

In the last few years, Online Social Networks (OSN) have experienced growth in the number of users, becoming an increasingly embedded part of people’s daily lives. Privacy expectations of OSNs are higher as more members start realizing potential privacy problems they face by interacting with these systems. Inspection methods can be an effective alternative for addressing privacy problems because they detect possible defects that could be causing the system to behave in an undesirable way. Therefore, we proposed a set of privacy inspection techniques called PIT-OSN (Privacy Inspection Techniques for Online Social Network). This paper presents the description and evolution of PIT-OSN through the results of a preliminary empirical study. We discuss the quantitative and qualitative results and their impact on improving the techniques. Results indicate that our techniques assist non-expert inspectors uncover privacy problems effectively, and are considered easy to use and useful by the study participants. Finally, the qualitative analysis helped us improve some technique steps that might be unclear.

Published: February 2020

Tests that evaluate individual strategies of visual exploration may be useful for uncovering deviations from typical development, such as autism spectrum disorder and dyslexia. One subgroup of visual exploration tests, called cancellation tests, requires the identification of specific targets surrounded by distractors. However, the lack of automated versions of these tests limits their availability to a broader audience. In the present paper, we present an automated version of a cancellation test: the cars’ test. The test is designed to be used by specialists, optimizing both its application and the analysis of collected data. First, we evaluated the cars’ test in a group of six to nine-years-old children enrolled in a private school, 22 children in total. Then, after some modifications based on the observations made during the first test (increase in the number of targets and distractors on the screen, for example), a second test was performed in a public school with a larger group of children, 82 participants, allowing a better statistical analysis of the collected data. The results suggest that the cars’ test is useful in providing information about visual exploration strategies adopted by children and is in agreement with the results of similar tests found in the literature.

Episemantics: Aboutness as Aroundness
Authors: Hauser Elliott , Tennis Joseph T.
Published: February 2020

Aboutness ranks amongst our field’s greatest bugbears. What is a work about? How can this be known? This mirrors debates within the philosophy of language, where the concept of representation has similarly evaded satisfactory definition. This paper proposes that we abandon the strong sense of the word aboutness, which seems to promise some inherent relationship between work and subject, or, in philosophical terms, between word and world. Instead, we seek an etymological reset to the older sense of aboutness as “in the vicinity, nearby; in some place or various places nearby; all over a surface.” To distinguish this sense in the context of information studies, we introduce the term episemantics. The authors have each independently applied this term in slightly different contexts and scales (Hauser 2018a; Tennis 2016), and this article presents a unified definition of the term and guidelines for applying it at the scale of both words and works. The resulting weak concept of aboutness is pragmatic, in Star’s sense of a focus on consequences over antecedents, while reserving space for the critique and improvement of aboutness determinations within various contexts and research programs. The paper finishes with a discussion of the implication of the concept of episemantics and methodological possibilities it offers for knowledge organization research and practice. We draw inspiration from Melvil Dewey’s use of physical aroundness in his first classification system and ask how aroundness might be more effectively operationalized in digital environments.
Population Policy as a Means for Bio-Politics: The Cases of Romania and China
Authors: Önder Erol Pelin
Published: February 2020

After the discovery of “population” in modern society, domination over the body has been enacted by a set of interventions which are called regulatory control, or bio-politics by Michel Foucault. From the eighteenth century onwards, bio-politics has involved any kind of intervention which acts as means for forming the population according to the wills of those with power. This has led to an era of bio-politics in which fertility in particular has become regulated in accordance with political economy. Hence the body, especially the female body, has been reduced to an economic object by detaching her identity, personal aspirations and desires. In turn, sexuality becomes a subject of economic interventions through pronatalist and/or antinatalist politics. In either way, those interventions should be methodologically regarded as instruments of bio-politics. This paper specifically focuses on pronatalist and antinatalist politics as bio-political instruments in the well-known Romanian case and the Chinese case by drawing upon the Foucauldian perspective of bio-politics.

Published: February 2020

The China-Pakistan Economic Corridor (CPEC) is a well-crafted economic partnership
between China and Pakistan which is expected to bring economic development and
prosperity not only for the two neighboring countries but also for the whole South Asia. It is considered central to China-Pakistan relations and the CPEC will link Kashgar to Gawadar port through the extension of Silk Road initiative which is widely known as Belt and Road Initiative (BRI). With the investment of 46 billion US dollars, its completion is expected by 2030. CPEC is the most discussed and debated economic partnership and it has great geostrategic importance for Pakistan to counterbalance Indian influence in South Asia. However, the focus on geopolitical and location of the route has been dominated the important questions concerning “How Pakistan should ensure its economic benefit out of this mega project?” This paper, therefore, aims to develop a theoretical framework and put forward relevant recommendations on how Pakistan can ensure its economic benefits as compared to the forecasted economic and political benefits of China and the challenges ahead.

This study was conducted in central Iran among all first-year university students studying
engineering courses at Arak University of Technology. All students (No = 310) were included
in this study. Instruments used mostly consisted of a computer anxiety questionnaire plus a learning style questionnaire. The data was analyzed by both descriptive and inferential
statistics (Mean, Frequency, Standard Deviations, Independent T-test as well as Point
Biserial Correlation Coefficient). The results indicated that there was a statistically
significant relationship between computer anxiety and sensory-intuitive learning styles, in
that the students having sensory learning style suffered from computer anxiety more
frequently than the student having intuitive learning styles. In addition, there was a
statistically significant relationship between computer anxiety and verbal-visual learning
style, given that the students having visual learning style suffered from computer anxiety
more than the students having verbal learning style. No statistically significant relationship, however, was found between computer anxiety and gender.
Liquid Biopsy in Breast Cancer: A Focused Review
Authors: Tay Timothy Kwang Yong , Tan Puay Hoon
Published: February 2020

Context.—

The role of liquid biopsy in cancer management has been gaining increased prominence in the past decade, with well-defined clinical applications now being established in lung cancer. Recently, the US Food and Drug Administration also approved the Therascreen PIK3CA RGQ polymerase chain reaction assay as a companion diagnostic assay to detect PIK3CA mutations in breast cancer for both tissue and liquid biopsies, bringing the role of liquid biopsy in breast cancer management to the fore. Its utility in other aspects of breast cancer, however, is yet to be clearly defined.

Objective.—

To review the studies that looked at liquid biopsies in breast cancer and examine their potential for clinical application in the areas of early diagnosis, prognostication, monitoring disease response, detecting minimal residual disease, and predicting risk of progression or relapse. We focus mainly on circulating tumor cells and circulating tumor DNA.

Data sources.—

Peer-reviewed articles in PubMed.

Conclusions.—

Liquid biopsies in breast cancers have yielded promising results, especially in the areas of monitoring treatment response and predicting disease progression or relapse. With further study, and hopefully coupled with continued improvements in technologies that isolate tumor-derived materials, liquid biopsies may go on to play a greater role in the breast cancer clinic.

Scanning and Transmission Electron-Microscopic Studies on the Lingual Tonsil of the Buffalo (Bubalus bubalis)
Authors: Girgiri Ibrahim Alhaji , Kumar Pawan
Published: February 2020

The present study examined lingual tonsil of six buffaloes of the local mixed breed by scanning and transmission electron-microscopy to elucidate their ultrastructural features. The lingual tonsil presented folded mucosa having longitudinally oriented folds which were separated by grooves. The surface mucosa showed a squamous arrangement of cells which delineated from the adjacent cells. The surface of these cells at a higher magnification presented the microplicae of different arrangements which were mainly of closed pattern type and resembled fingerprints of humans. The luminal openings of glandular ducts on the free surface presented varying shapes. The transmission electron-microscopy described ultrastructural details of the different strata of the stratified squamous keratinised, non-keratinised and reticular epithelia. The propria-submucosa contain reticular cells, fibroblast, lymphoid cells, plasma cells, granulocytes and interdigitating cells. Few high endothelial venules observed and the cytoplasmic process of these endothelial cells contained small vacuoles equivalent to vesiculo-vacuolar organelles, membrane-bound bodies and vacuolated structures.

Published: February 2020

The objective of this study was to find out the level of emotional intelligence of preschool teachers-methodologists with the purpose of further professional advancement (enhancing their emotional competence). Tools applied for collecting and processing statistics were the following: survey results, methodologist’s checklists of observation of conducting classes by the teacher, N. Hall’s Emotional Intelligence Test, questionnaires for parents. There was also a survey of training participants followed by written feedback. STATA software was used for data processing, and the online TextAnalyzer utility was used to process free responses from the parent questionnaires. It is found that the system of formation of emotional intelligence, based on the training we have developed, has a positive impact on the development of emotional intelligence of preschool teachers-methodologists. The above approach enhances the knowledge of preschool teachers about their emotions, senses and feelings, contributing to the development of their ability to understand their own emotions. After the training, 7.14% of the participants showed a low level as opposed to the initial level of 33.33%. The medium level rose significantly, from 60.0% to 78.6%. And the high level of awareness of emotional intelligence in teachers has increased more than twice - from 6.67% to 14.29%. The arithmetical mean for raw scores also increased - from 43.87 to 57.54, thus confirming that the system used in training allows developing strategies for modulation of their emotions, introducing the training participants to the techniques of expression of their emotions and developing a range of emotional competency skills aimed at overcoming emotive situations. Since during the analysis of the lessons by the methodologist the teacher had to respect both the positive and negative response of the methodologist and since respect is a component of leadership, we can say that the feedback contributed to the development of leadership qualities of teachers. Regarding pedagogical skills, provided that the teacher constantly works on self-improvement of emotional intelligence, we state that the level of the teacher’s pedagogical skills also improves. We consider it reasonable to further explore the possibilities of developing the competence of emotional intelligence in future teachers during their study in higher educational institutions and preschool teachers.

Fragile X Syndrome (FXS) is the most common known inherited form of intellectual disability (ID), caused by a CGG repeat expansion of the FMR1 gene. The aimed of the study was to screen FMR1 mutation among the ID population followed by cascade testing in a remote area. A PCR-based method was used to screen FMR1 expanded alleles using dried blood spot cards in Flores Island, one of the very remote areas in East Indonesia. The screening included 130 males and 81 females from three schools of children with ID. The screening identified three individuals with expanded alleles including two full mutation males and one premutation male. No expanded allele was detected in females. A second blood sample for confirmatory diagnosis was done using Southern blot. Cascade testing in a remote area of Indonesia found a multigenerational family with a large number of cases with FXS. FXS screening of ID populations followed by cascade testing in positive FXS family in a remote area with challenging accessibility is recommended.

Појам стидљивост је у широкој употреби у свакодневном говору, али није у потпуности схваћен и објашњен. Укљученост ученика у наставу испитали смо кроз компетенције (емоционалне, социјалне, когнитивне) ученика и њихове ставове о стидљивости. Кључно питање у овом истраживању било је да ли различит ниво стидљивости детерминише (емоционалну, социјалну и когнитивну) укљученост ученика у наставу.
Marcas de vida na paisagem de São Paulo: a “pixação” como epitáfio de uma cidade vandalizada
Authors: Barbosa Pereira Alexandre
Published: February 2020

From the perspective of classifying the pixação —a brazilian tag graffiti— as an environmental crime, the article contrasts this practice with the historical processes of exclusionary urbanization and attacks on the environment established in the city of São Paulo, Brazil. It is shown, for example, that in spite of the fact that the city has rectified and ravaged its rivers and that almost a thousand people a year die in their transit along them, the pixação continues to be considered the city’s main environmental problem. Thus, based on the discussions on biopower and necropolitics, the pixação is presented as a possibility of life experience that is shaped within the landscape of a city whose operation consists of segregating and deciding who can live and who must die or be brutalized.
Phosphorylation systems in symbiotic nitrogen-fixing bacteria and their role in bacterial adaptation to various environmental stresses
Authors: Lipa Paulina , Janczarek Monika
Published: February 2020

Symbiotic bacteria, commonly called rhizobia, lead a saprophytic lifestyle in the soil and form nitrogen-fixing nodules on legume roots. During their lifecycle, rhizobia have to adapt to different conditions prevailing in the soils and within host plants. To survive under these conditions, rhizobia fine-tune the regulatory machinery to respond rapidly and adequately to environmental changes. Symbiotic bacteria play an essential role in the soil environment from both ecological and economical point of view, since these bacteria provide Fabaceae plants (legumes) with large amounts of accessible nitrogen as a result of symbiotic interactions (i.e., rhizobia present within the nodule reduce atmospheric dinitrogen (N2) to ammonia, which can be utilized by plants). Because of its restricted availability in the soil, nitrogen is one of the most limiting factors for plant growth. In spite of its high content in the atmosphere, plants are not able to assimilate it directly in the N2 form. During symbiosis, rhizobia infect host root and trigger the development of specific plant organ, the nodule. The aim of root nodule formation is to ensure a microaerobic environment, which is essential for proper activity of nitrogenase, i.e., a key enzyme facilitating N2 fixation. To adapt to various lifestyles and environmental stresses, rhizobia have developed several regulatory mechanisms, e.g., reversible phosphorylation. This key mechanism regulates many processes in both prokaryotic and eukaryotic cells. In microorganisms, signal transduction includes two-component systems (TCSs), which involve membrane sensor histidine kinases (HKs) and cognate DNA-binding response regulators (RRs). Furthermore, regulatory mechanisms based on phosphoenolopyruvate-dependent phosphotranspherase systems (PTSs), as well as alternative regulatory pathways controlled by Hanks-type serine/threonine kinases (STKs) and serine/threonine phosphatases (STPs) play an important role in regulation of many cellular processes in both free-living bacteria and during symbiosis with the host plant (e.g., growth and cell division, envelope biogenesis, biofilm formation, response to stress conditions, and regulation of metabolism). In this review, we summarize the current knowledge of phosphorylation systems in symbiotic nitrogen-fixing bacteria, and their role in the physiology of rhizobial cells and adaptation to various environmental conditions.

We review the concept of ecosystem resilience in its relation to ecosystem integrity from an information theory approach. We summarize the literature on the subject identifying three main narratives: ecosystem properties that enable them to be more resilient; ecosystem response to perturbations; and complexity. We also include original ideas with theoretical and quantitative developments with application examples. The main contribution is a new way to rethink resilience, that is mathematically formal and easy to evaluate heuristically in real-world applications: ecosystem antifragility. An ecosystem is antifragile if it benefits from environmental variability. Antifragility therefore goes beyond robustness or resilience because while resilient/robust systems are merely perturbation-resistant, antifragile structures not only withstand stress but also benefit from it.

Due to the popularity and low cost of rapid mobile internet connection, live-streaming service is now booming. Some of these users who provide live video shows to the public are famous and known as vloggers or YouTube celebrities. The content of the live show is diverse. Some YouTubers broadcast video of their computer screen when playing an online game; others cook, work out, or put on makeup on camera. Nearly anything from one’s daily life is fair game. The abundant live video streaming content attracts youngsters as well as adults. To understand the viewers’ motivation for watching live video streaming, this study used a self-reporting online questionnaire survey. A total of 374 responses were received and analyzed to ascertain the motives of viewing live video streaming. Based on the empirical survey results, we propose a motivation of YouTuber model composed of four motive categories: leisure, celebrity worship, social connection, and voyeurism. These four categories can be divided into eight motives, including passing time, entertainment, relaxation, celebrity identification, vicarious participation, companionship, social interaction, and voyeurism.
From Shape to Function: The Next Step in Bioprinting

In 2013, the “biofabrication window” was introduced to reflect the processing challenge for the fields of biofabrication and bioprinting. At that time, the lack of printable materials that could serve as cell‐laden bioinks, as well as the limitations of printing and assembly methods, presented a major constraint. However, recent developments have now resulted in the availability of a plethora of bioinks, new printing approaches, and the technological advancement of established techniques. Nevertheless, it remains largely unknown which materials and technical parameters are essential for the fabrication of intrinsically hierarchical cell–material constructs that truly mimic biologically functional tissue. In order to achieve this, it is urged that the field now shift its focus from materials and technologies toward the biological development of the resulting constructs. Therefore, herein, the recent material and technological advances since the introduction of the biofabrication window are briefly summarized, i.e., approaches how to generate shape, to then focus the discussion on how to acquire the biological function within this context. In particular, a vision of how biological function can evolve from the possibility to determine shape is outlined.

Controlling the formation of bimetallic heterogeneous nanogaps structures have many applications in the plasmonics and catalysis fields. Here, a simple and systematic method is developed to fabricate tunable and stable Au–Ag nanowire‐based plasmonic metamaterials. The sub‐10 nm Au–Ag bimetallic heterogeneous nanogaps with desirable optical properties are fabricated by a simple, ultrarapid, and robust nanoskiving technique. Compared to the monometallic linear Ag–Ag and Au–Au nanogaps, the Au–Ag bimetallic heterogeneous nanogaps exhibit remarkable surface enhanced Raman spectroscopy (SERS) enhancement properties due to the nanogaps between the adjacent Au/Ag nanowires, and the Ag/Au bimetallic composite film. In addition, 3D bimetallic heterogeneous nanogaps are built and produce much stronger electric fields than those of the 1D linear nanogaps. The sub‐10 nm Au–Ag heterogeneous nanogaps are promising to be used in SERS substrate, plasmon devices, catalysis, and printed electronics.

All‐polymer and semitransparent organic photodetectors (OPDs) fabricated through lamination on flexible substrates are demonstrated. Through lamination both bilayer and bulk heterojunction (BHJ) configurations for two different all‐polymer blends are easily made, and characterized in terms of detectivity, linear dynamic range (LDR), and bandwidth. These devices show high detectivity up to 1011 Jones. The importance of measured noise rather than estimated shot noise in detectivity calculation is discussed and emphasized. With this high detectivity and with the geometric flexibility due to the polymer materials, these detectors can be attached to curved surfaces for optical detection. Their use at fingertips for heart rate sensing is demonstrated. These devices also have a very wide bandwidth of more than 300 kHz and an LDR of 75 dB. As such the, roll‐to‐roll compatible lamination method shows great potential for high‐performance OPDs fabrication.
Selective Binding of Dopamine and Epinephrine in Water by Molecularly Imprinted Fluorescent Receptors
Authors: Duan Likun , Zhao Yan
Published: February 2020

Catecholamines play important roles in biology but their structural similarity makes it challenging to construct synthetic receptors with selective binding. A combination of covalent and noncovalent binding groups in the hydrophobic core of water‐soluble nanoparticles enabled them to recognize dopamine and epinephrine with an association constant (Ka) of 3–4×104 M−1 in water, an order of magnitude higher than those of previously reported synthetic hosts. In addition, minute structural changes among analogues were detected including the addition or removal of a single hydroxyl or methyl group.

The expected imminent widespread use of electromobility in transport systems draws attention to the possible effects of human exposure to magnetic fields generated inside electric vehicles and during their recharge. The current trend is to increase the capacity of the battery inside the vehicles to extend the available driving range and to increase the power of recharging columns to reduce the time required for a full recharge. This leads to higher currents and potentially stronger magnetic fields. The Interoperability Center of the Joint Research Center started an experimental activity focused on the assessment of low‐frequency magnetic fields emitted by five fast‐charging devices available on the market in recharge and standby conditions. The aim of this study was to contribute to the development of a standard measurement procedure for the assessment of magnetic fields emitted by direct current charging columns. The spectrum and amplitudes of the magnetic field, as well as exposure indices according to guidelines for the general public and occupational exposure, were recorded by means of a magnetic field probe analyzer. The worst‐case scenario for instantaneous physical direct and indirect effects was identified. Measurements within the frequency range of 25 Hz–2 kHz revealed localized magnetic flux density peaks above 100 μT at the 50 Hz frequency in three out of five chargers, registered in close proximity during the recharge. Beyond this distance, exposure indices were recorded showing values below 50% of reference levels. Bioelectromagnetics. 2020;41:308–317 © 2020 The Authors.
