PET Radiomic Features Variability: A Phantom Study on the Influence of Reconstruction and Discretization Method
Authors: Antônio Dórea Machado Marcos , Pereira Pita Jean Lucas , Martins Netto Eduardo
Published: July 2021

We aimed to explore the variability of PET radiomic features for varying reconstruction methods and quantification settings. The IQ-NEMA phantom was scanned 5 times with a sphere to background F-18 concentration ratio of 10:1. The activity and the image duration were matched to result typical counting statistics for 18F-FDG oncologic examinations. The images were reconstructed with OSEM and PSF reconstructions, then 99 radiomic features were extracted using two discretization methods: fixed bin number (FBN = 16, 32 and 64 gray levels) and fixed bin width (FBW=0.25). This scheme resulted in a total of 1,188 features, classified as having low (<5.0%), intermediate (5-29.9%) or high (≥30%) variability. In general, FBW discretization yielded more stable features. A total of 499, 558 and 131 features had low, intermediate and high variability, respectively. First order features such as energy and entropy and textural features such as entropy (GLCM), long run emphasis and short run emphasis (GLRLM) were more likely to present low variability, regardless the reconstruction and discretization method. Other textural features such as large area emphasis (GLSZM), zone percentage (GLSZM) and complexity (NGTDM) had more frequently intermediate or high variability.These findings could facilitate features’ selection for further PET radiomic applications.

Published: July 2021

Wet welding procedures of Class A structural ship steels frequently fail to comply with the American Welding Society (AWS) D3.6M, Underwater Welding Code, in the maximum hardness criterion for the heat-affected zone (HAZ). The maximum hardness accepted in a welded joint is 325 HV for higher-strength steel (yield strength > 350 MPa). In multi-pass welds, this problem occurs frequently and is restricted to the HAZ of the capping passes. The HAZ of the root and filling passes are softened by the reheating promoted by their respective subsequent passes. This paper presents the results of exploratory research into postweld underwater electromagnetic induction heating. The objective of the research was to evaluate the ability of induction heating to soften the specific high-hardness HAZs in underwater conditions. The results showed that this technique could reduce the maximum HAZ hardness of low-carbon structural ship steel welds to values below 325 HV, which is the maximum accepted by AWS for Class A welds. The induction-heated zone reached a maximum depth of about 10 mm, which is considered adequate to treat the HAZ of cap-ping passes in underwater wet welds.

Published: July 2021

This paper examines irrigation management within the Tunisian Water Users Association (WUA),in Nadhour public irrigated area (central of Tunisia). The functioning of 14 WUAs was evaluated based on questionnaires and related interviews. The methodology of this study consists of two main steps; (i) an estimation of technical efficiency scores of 90 smallholder farmers and the sub-vector of WUE (Water Use efficiency) using the non-parametric DEA model, (ii) a regression of a Tobit model to test the hypothesis regarding explanatory variables of differentiated technical efficiency scores. The investigation shows an average technical efficiency of 70.8% and WUE of 64.8%. It highlighted the Water turn, the infrastructure state, the water supply shortage, corruption, and free-riding behaviors as tightly correlated factors with farm’s productivity. This suggests that there is potential to improve production efficiency by implementing targeted programs and rules for inefficient farmers. The findings of this study show that it is important to fight corruption in the water sector by an increased government oversight, reform of regulations, and increased accountability
Food security and European migrant crisis: Case of Mediterranean area
Authors:   Danilo Đokić, Bojan Matkovski, Žana Jurjević, Stanislav Zekić
Published: July 2021

This paper focuses on a possible connection between food security and the migrant crisis that began in 2015, which had a tremendous impact on the European Union as well as on the Mediterranean area. The goal of this paper is to determine if there is a correlation between the number of migrants and the levels of food security in both their homeland countries and destination countries. The Promethee method was used to attempt to answer this question. Unfortunately, the analysis is limited due to lack of data for certain countries concerning food security caused by current poor political situations. Nevertheless, the results showed that the best-ranked countries by food security are mostly EU countries. These countries do not have issues with food security, especially in comparison to countries in the Middle East. Also, countries with a high level of food security and political stability have the highest influx of migrants, which suggests there is also an economic motivation for migration. Finally, the analysis confirmed a strong correlation between countries’ achieved level of food security and the number of migrants.
Évaluation de la rentabilité et de la productivité totale des facteurs de production des exploitations céréalières : cas de la culture du blé dur au Nord de la Tunisie
Authors:   Zouhair Ameur Rached, Boudiche Sonia, Chebil Ali, Khaldi Raoudha
Published: July 2021

The main objectives of this paper are to assess the production costs and to measure the total factor productivity (TFP) of durum wheat production for a sample of cereal farmers in the North of Tunisia. Our hypothesis is that improvement of these indicators can reduce the production costs and consequently the improvement of producers' incomes. To test this hypothesis, a survey was carried out with 232 cereal farms in the subhumid region in the North of Tunisia cultivating durum wheat. The reconstituted costs approach was used to estimate the production costs. The results obtained show that total costs, production costs and net margins of durum wheat vary according to the farm size. About 67% of surveyed farms make a positive net margin. The empirical results of the regression reveal that productivity is negatively affected by the farm size, the new varieties demanding water and the investments made by the farm while it is affected positively by crop rotations

Authors:   Houria Hadjoune, Omar Kihal, Ahcène Kaci, Fathi Abdellatif Belhouadjeb
Published: July 2021

In the region of M'Sila, a steppe zone and characteristic of a dominant agro-pastoral framework, the local olive sector has certainly grown in terms of area expansion, but the information available indicates that its future in terms of performance is dependent on a series of internal and external factors. The aim of this article is to highlight the main explanatory variables by analyzing the strengths and weaknesses of the sector, the opportunities and threats linked to its environment. Two methods are used: the first, SWOT, constitutes a structured diagnostic framework and a universal decision-support tool. The second, the causality analysis, according to the Parmenides EIDOS tool, makes it possible to obtain a hierarchy of relations in the sector based on the opinions of the intervening actors. The data used come from the bibliographic summary of a series of studies and the results of a survey carried out in 2017 in the field. The results obtained show that the internal factors are linked to the characteristics of the farms, to the production systems, and to the surrounding conditions of the value chain. External factors are linked to the dynamics of national and global markets.

Analysis of the Arctic polar vortex dynamics during the sudden stratospheric warming in January 2009
Authors: Zuev V. V. , Savelieva E. S. , Pavlinsky A. V.
Published: July 2021

The Arctic polar vortex is often affected by wave activity during its life cycle. The planetary Rossby waves propagating from the troposphere to the stratosphere occasionally lead to the displacement or splitting of the polar vortex, accompanied by sudden stratospheric warming (SSW). In January 2009, one of the largest SSWs was observed in the Arctic. In this work, the dynamics of the polar vortex during the 2009 SSW is considered using a new method that allows one to estimate the vortex area, the wind speed at the vortex edge, the mean temperature and ozone mass mixing ratio inside the vortex, based on the fact that the Arctic vortex edge at the 50 and 10 hPa pressure levels is determined by the geopotential values, respectively, 19.5. 104 and 29.5. 104 m2 /s2 , using the ERA5 reanalysis data. The application of this method is justified for the Arctic polar vortex, which is characterized by significant variability, especially during the period of its splitting. The splitting of the polar vortex in 2009 was observed on January 24 and 28, respectively, in the middle and lower stratosphere. About a week after the splitting, the vortices became closer in characteristics to small cyclones, which completely collapsed within 1–3 weeks. The influence of planetary wave activity on the polar vortex does not always lead to its breakdown. Short-term splitting of the polar vortex is sometimes observed for several days after which the polar vortex strengthens again and PSCs form inside the vortex. Such a recovery of the polar vortex is most likely to occur in the winter. Based on the analysis of the dynamics of the Arctic polar vortex for 1979–2020 and using the example of the 2009 SSW, we showed that when the vortex area decreases to less than 10 million km2 and the mean wind speed at the vortex edge decreases below 30 and 45 m/s, respectively, in the lower and middle stratosphere, the polar vortex becomes a small cyclone (with significantly higher temperatures within it), which usually collapses within 3 weeks.

Business competition in this case shows the public demand and supply in this case applies. The development of the business world is able to provide offers that tend to be more attractive to both experienced and non-experienced Human Resource. This makes employees in a company in a certain period tend to have consideration to move and choose more attractive offers from other companies. This study generally aims to analyze the determinants of employee turnover factors. This research is a quantitative study using Structural Equation Modeling (SEM) with a total sample of 50 people with analysis tools, namely SMART PLS 3.0. The results of this study explain in a direct effect that employee motivation is not affected by service efforts to the client as part of the work carried out by employees and also not affected by employee teamwork. However, employee motivation is influenced by relationships between employees, employee responsibilities at work, employee work behavior. The desire of employees to change jobs is influenced by employee motivation. Indirectly, the desire of employees to change jobs is not influenced by service to the client and teamwork. Conversely, the desire of employees to change jobs is influenced by factors of work relations between employees, employee responsibilities with employee motivation as mediating factors, and employee work behavior factors. Suggestions for researchers can then use export import companies originating from outside Indonesia where blending the culture of the organization will have an important role.

Recycling is one of the efforts that can be done to save the environment and can be a fun activity to do together. There are so many benefits that can be extracted from recycling activities and of course it will be very valuable for children. 3R (reduce, reuse, recycle) is an innovation in order to provide learning media for early childhood. In addition to learning to take advantage of children's recycling waste, the purpose of this training is also to learn how to sharpen the motor by adding origami elements to the recycling work in the form of piggy bank that has been made. This study uses a collaborative and participatory action research method (PAR), which is a research activity carried out by involving the community so that they feel that they have a stake in the activity program and intends to participate actively in solving community-based problems. This study uses respondents of children aged 7-9 years who are from the Dharma Suci RPTRA located in North Jakarta. The results of this study show that children give positive responses in the development of fine motor skills by making hand movements cutting, sticking and folding. The selection of used milk boxes is quite appropriate, because most of them see and have used milk boxes in each respondent's house. Children love the theme of endangered animals because, these animals are not animals that they can see everyday. The choice of piggy bank as a form of processed processed goods made them enthusiastic to start saving early.

Authors: Dao Vu Anh , Thuy Tran Thi Thanh , Dung Truong Cao , Quyen Nguyen Xuan
Published: July 2021

This paper presents a numerical simulation investigation on the bit error rate in a chaotic-secured fiber channel and a conventional fiber channel when propagating independently. The investigated communication system uses the pulse-amplitude modulation scheme (4-PAM) at the bit rate of 10 Gbps, the fiber length of 100 km, and the operation wavelength of 1550 nm. Our simulation results demonstrate both chaotic and non-chaotic transmission channels can well operate with the bit rate up to 20 Gbps with the BER smaller than 10-5 if dispersion and fiber loss issues are appropriately compensated without needing forwarderror-correction, showing high potential in physically secured optical fiber communication systems.

The antenna array achieves a gain max up to 7 dBi, and the angles of the main beam directions of -41°, -12°, +15°, +48° in a horizontal plane. The beamwidth of the four main beams is from 26°  to 31.8° in E-plane and from 38.5° to 55.4° in H-plane. The advantage of the antenna is the planar structure and compact dimension of 200×230mm2. The proposed antenna is suitable for ISM band.
African Sartorial Culture and the Question of Identity: Towards an African Philosophy of Dress
Authors: Fayemi Ademola Kazeem
Published: July 2021

This paper is a critical interrogation of the apparel culture as a marker of African identity in traditional and contemporary Africa. The article philosophically discusses the sartorial culture of sub-Saharan Africans in the light of its defining elements, identity, and non-verbal communicative proclivities. Focusing on the Yoruba and the Ashanti people, the author argues that African dress expresses some symbolic, linguistic, and sometimes hidden, complex and immanent meaning(s) requiring extensive interpretations and meaning construction. With illustrative examples, he defends the position that the identity of some cultural regions in Africa can be grouped together based on the original, specific techniques and essence of dress that they commonly share. Against the present absence of an African philosophy of dress in the African sartorial culture and knowledge production, he argues the imperativeness of an African philosophy of dress, its subject matter, and connections to other cognate branches of African philosophy, and the prospects of such an ancillary African philosophy.
Milgram revisited: The role of belief in science
Authors: Messick Kyle J.
Published: July 2021

Belief in science is a term applied to assess the degree to which individuals see science as a positive and moral force. This allegiance to science as a guide for societal progress changes on a cultural level over time, with there being a particularly strong contrast between the widespread distrust of science in modern times and the ‘Golden Age of Futurism’ that contextualized Milgram’s infamous obedience experiments. Milgram’s experiments have been critically analyzed for their methods and conclusions, and although many factors have been proposed as possible contributors, society’s relationship with science during that era is largely overlooked. This presentation applies belief in science as a likely contributing factor in Milgram’s experiments through two primary routes: 1) the experiments took place during a timeframe characterized by a rich embracing of science through major innovations, portrayals in popular media, and celebrity scientists, and 2) the use of belief in science as a prime in a multitude of ways, including legitimizing the experiment with a scientific textbook and by advertising Yale University as the location of the experiments. Belief in science should be considered among contributing factors in discussing Milgram’s outcome, as it could contribute to obedience through an appeal to scientific progress, calling further into question Milgram’s wartime atrocity applications, and offers an additional reason as to why the obedience experiments would inevitably differ in a modern context.

Published: July 2021

This paper aims to examine export, import and trade intensity, export specialization index, Herfindahl-Hirschman index for bilateral concentration and diversification indices to analyze the specializations, structure and trends of deficit in bilateral trade between Bangladesh and China from 1995 to 2018 and policy recommendations in this regard. The results reveal that the gap of export and import intensity between Bangladesh and China is widening rapidly perennial. The export specialization indices expose very significant outcomes where among the analyzed 16 sectors; 6 sectors exhibit high specialization, 3 sectors demonstrate medium, 3 sectors exhibit low and the rest of the 4 sectors disclose no specialization for Bangladesh’s export to China. The findings of the Herfindahl-Hirschman Index (HHI) reveal that from 1995 to 2010 the export of Bangladesh to China concentrated within few sectors but from the year 2011 to 2018 the export has been reclassifying steadily into diversification. The overall analysis of the indices suggests the necessity to be improved of the level of intra-industry trade between China and Bangladesh. Moreover, emphasis should be given to the sectors having a high specialization that endure the capacity to narrow the trade deficit. Furthermore, the export baskets of Bangladesh to China require to be diversified. Hereafter, various measures and implications are also suggested in the policy recommendation for further improvement.

Prior research suggests that Twitter users in the United States are more politically engaged and more partisan compared to the American citizenry -- a public that is otherwise characterized by low levels of political knowledge and disinterest in political affairs. This study seeks to understand this disconnect by conducting an observational analysis of the most popular accounts on American Twitter. We identify opinion leaders by drawing a random sample of ordinary American Twitter users and observing whom they follow. We estimate the ideological leaning and political relevance of these opinion leaders as well as crowd-source how they are perceived by ordinary Americans. We find little evidence that American Twitter is as politicized as is made out to be, with politics and hard news outlets constituting a small subset of these opinion leaders. We find no evidence of polarization among these opinion leaders either. While certain professional categories such as political pundits and political figures are more polarized than others, the overall polarization dissipates further when we factor in the rate at which the opinion leaders tweet: a large number of vocal non-partisan opinion leaders drowns out the partisan voices on the platform. Our results suggest that the degree to which Twitter is political, has likely been overstated in the past. Our findings have implications about how we use Twitter to represent public opinion in the United States.

Background: The UK’s test, trace, and isolate system are key measures to reduce the impact and spread of the COVID-19. However, engagement with and adherence to guidance on testing, self-isolation, and providing details of contacts can be low and interventions are needed. This qualitative study aimed to identify the key factors affecting adherence to test, trace, and isolate behaviours using the Theoretical Domains Framework (TDF). Methods: We conducted six online focus groups between October 2020 and February 2021 with people living in Sheffield who came into close contact with others in work or social settings (N = 30). The focus groups explored capability, opportunity, and motivational barriers to adherence to test, trace, and isolate behaviours. Framework analysis was used to code the data into TDF domains. Results: There is a complex relationship between the factors affecting COVID-19 symptom identification, testing, and self-isolation. People who perceived significant barriers to testing and self-isolation were less likely to interpret potential symptoms as COVID-19, and perceiving barriers to self-isolation reduced the likelihood of requesting a test. Concerns about the negative consequences of self-isolation for themselves and others were common and also influenced willingness to pass on details of contacts. There was a lack of trust in the Test and Trace system, with people wanting further evidence of being at risk of infection. Conclusions: Communications and interventions to increase adherence to test, trace, and isolate strategies need to consider the interplay of these behaviours and their influences and target them collectively. Efforts to promote testing should focus on the range of barriers to self-isolation, especially increasing financial and practical support, and include new messaging to promote symptom identification.
Chronic Breast Abscess Caused by Corynebacterium Kroppenstedtii

Published: July 2021

Corynebacterium is being increasingly isolated in specimens to be proven as a causative organism in clinical disease, especially breast abscesses and mastitis. Specifically, Corynebacterium kroppenstedtii lacks the typical mycolic acids of the cell envelope, requiring lipid rich areas to grow, hence the mammary areas being ideal for its proliferation. Conservative treatment is routinely first line in breast abscess, however commonly prescribed antibiotics such as beta lactams and fluoroquinolones, are hydrophilic and do not penetrate in lipid rich environments such as the breast, thus patients are left partially treated without complete resolution of the disease process. This case report highlights the importance of considering C. kroppenstedtii, especially if recurrent infection is seen. Microbiologists should be alerted to specialized growth conditions and tools for appropriate culture such that clinicians can use a multimodal approach with early surgical intervention alongside antibiotic treatment to maximize clinical cures and reduce recurrence.
The effect of lateral variations in Earth structure on Last Interglacial sea level

Published: July 2021

It is generally agreed that the Last Interglacial (LIG; 130 – 115 ka)was a time when global average temperatures and global mean sea level were higher than they are today. However, the exact timing, magnitude, and spatial pattern of ice melt is much debated. One difficulty in extracting past global mean sea level from local observations is that their elevations need to be corrected for glacial isostatic adjustment (GIA), which requires knowledge of Earth’s internal viscoelastic structure. While this structure is generally assumed to be radially symmetric, evidence from seismology, geodynamics, and mineral physics indicates that large lateral variations in viscosity exist within the mantle. In this study, we construct a new model of Earth’s internal structure by converting shear wave speed into viscosity using parameterisations from mineral physics experiments and geodynamical constraints on Earth’s thermal structure. We use this 3D Earth structure, which includes both variations in lithospheric thickness and lateral variations in viscosity, to calculate the first 3D GIA prediction for LIG sea level. We find that the difference between predictions with and without lateral Earth structure can be meters to 10s of meters in the near field of former ice sheets, and up to a few meters in their far field. We demonstrate how forebulge dynamics and continental levering are affected by laterally varying Earth structure, with a particular focus on those sites with prominent LIG sea level records. Results from four 3D GIA calculations show that accounting for lateral structure can act to increase local sea level by up to 1.5mat the Seychelles and minimally decrease it in Western Australia. We acknowledge that this result is only based on a few simulations, but if robust, this shift brings estimates of global mean sea level from these two sites into closer agreement with each other. We further demonstrate that simulations with a suitable radial viscosity profile can be used to locally approximate the 3D GIA result, but that these radial profiles cannot be found by simply averaging viscosity below the sea level indicator site.

Emotional disturbances are an inherent aspect of most mental disorders and possibly driven by impaired emotion regulation. The present study examines how exactly affected individuals differ from healthy individuals in regulating their emotions and whether individuals suffering from different mental disorders face similar or distinct difficulty in emotion regulation.We overcome earlier methodological constraints by using a seven-day experience sampling assessing the employment and effectiveness of six regulation strategies real-time in 55 individuals with current major depressive disorder, 52 individuals with borderline personality disorder (BPD), and 55 healthy individuals. All participants were female.Both clinical groups employed rumination and suppression more often and acceptance less often than healthy individuals. Depressed individuals ruminated even more often than individuals with BPD. Expressive suppression and rumination showed negative effects on subsequent emotions in all groups. Remarkably, both clinical groups were able to benefit from adaptive regulation strategies if they did select them.

Reputation is a fundamental feature of human sociality as it sustains cooperative relations among unrelated individuals. Research from various disciplines provides insights on how individuals form impressions of others, condition their behaviors based on the reputation of their interacting partners, and spread or learn such reputations. However, past research has often neglected the socio-ecological conditions that can shape reputation systems and their effect on cooperation. Here, we outline how social environments, cultural values, and institutions come to play a crucial role in how people navigate reputation systems. Moreover, we illustrate how these socio-ecological dimensions affect the interdependence underlying social interactions (e.g., potential recipients of reputational benefits, degree of dependence) and the extent to which reputation systems promote cooperation. To do so, we review the interdisciplinary literature that illustrates how reputation systems are shaped by the variation of prominent ecological features. Finally, we discuss the implications of a socio-ecological approach to the study of reputation and outline potential avenues for future research.
