PurposeIn this study, we investigate a strategy to reduce the local specific absorption rate (SAR) while keeping

constant inside the region of interest (ROI) at the ultra‐high field (B0 ≥ 7T) MRI.MethodsLocally raising the resonance structure under the discontinuity (i.e., creating a bump) increases the distance between the accumulated charges and the tissue. As a result, it reduces the electric field and local SAR generated by these charges inside the tissue. The

at a point that is sufficiently far from the coil, however, is not affected by this modification. In this study, three different resonant elements (i.e., loop coil, snake antenna, and fractionated dipole [FD]) are investigated. For experimental validation, a bumped FD is further investigated at 10.5T. After the validation, the transmit performances of eight‐channel arrays of each element are compared through electromagnetic (EM) simulations.ResultsIntroducing a bump reduced the peak 10g‐averaged SAR by 21, 26, 23% for the loop and snake antenna at 7T, and FD at 10.5T, respectively. In addition, eight‐channel bumped FD array at 10.5T had a 27% lower peak 10g‐averaged SAR in a realistic human body simulation (i.e., prostate imaging) compared to an eight‐channel FD array.ConclusionIn this study, we investigated a simple design strategy based on adding bumps to a resonant element to reduce the local SAR while maintaining

inside an ROI. As an example, we modified an FD and performed EM simulations and phantom experiments with a 10.5T scanner. Results show that the peak 10g‐averaged SAR can be reduced more than 25%.

Published: June 2020

AbstractThe need to respond to the complexity of Project Management (PM) in International Development and Aid Projects (IDAPs) has been acknowledged. Nevertheless, there are minimal endeavors to customize the standard PM Models in enhancing IDAPs within the more immense structures and longer field‐specific agendas for the interest of people reached by this specific type of projects in the man‐made crises. This article aims to examine the standard PMBOK(R) Guide and align it with requirements of IDAPs by emphasizing the Total Quality Management and Core Humanitarian Standers. A critical review has provided a conceptual model for better management of IDAPs that are implemented in man‐made crises such as Syrian refugee crisis in the Middle East, which adds value to how the standard PMBOK(R) Guide might be adopted or adapted for IDAPs requirements and the interest of better organizational effectiveness of International Non‐Governmental Organizations and vulnerable people alike.

Published: June 2020

SummaryBackgroundStress‐induced emotional eating is a risk factor for overweight and obesity. Previous research proposes both the human serotonin transporter gene (5‐HTTLPR) and child's reactive temperament are promising candidates to help explain individual differences in stress‐induced emotional eating and weight. Understanding the association between specific genotypes, reactive temperament factors, and stress‐induced emotional eating may inform the development of personalized and effective treatment for children who may be at risk for overweight and obesity.ObjectiveThe current study explored the conditional indirect effect of genetic and environmental susceptibility (i.e., the interaction between 5‐HTTLPR and reactive temperament) on weight (as measured by percent body fat) mediated by stress‐induced emotional eating.MethodOne hundred and forty‐seven children (4 to 6 years old; 50.3% female; 22.4% Hispanic), along with their primary caregiver, completed laboratory tasks and questionnaires that assessed the child's reactive temperament, stress‐induced emotional eating, and percent body fat.ResultsThe interaction between 5‐HTTLPR and impulsivity as well as with negative affectivity significantly predicted percent body fat. The interaction between 5‐HTTLPR and impulsivity as well as with negative affectivity significantly predicted both total calorie consumption and rate of total calorie consumption. However, the mediation aspect of this statistical model was not supported.ConclusionsChild reactive temperament is an important indicator of how children approach eating when stressed. Mental health providers may consider prescribing strategies to reduce emotional eating among children with the SL variant and moderate to high impulsivity as well as children with the LL variant and high negative affectivity.

Published: June 2020

AbstractThe theoretical investigation of heat dissipation for polymer‐bonded explosives (PBXs) is in high demand in explosive design in terms of safety and realibility, particularly as lack of effective experimental measurements. Here, we investigate the fundamental understanding of thermal transport across the heterogeneous interface between HMX and PVDF, by using the diffuse mismatch model and anharmonic inelastic model. This work explores the interfacial thermal conductance via ab initio calculation and derived phonon dispersions, phonon group velocities. For HMX‐PVDF interface, it is shown that low‐frequency phonon modes (especially lower than 10 THz) and two‐phonon elastic processes play dominant roles in the interface thermal transport. Furthermore, we present the calculated interfacial thermal conductance as a function of temperature. The thermal conductivity of mixture HMX‐PVDF system is analyzed with an effective medium approximation model. From these calculations, we give the thermal transport properties predictions of PBX for thermal conductivity enhancement and provides fundamental microscopic insights into phonon transport physics in PBX.
A foreign body experience

Published: June 2020

AbstractForeign body inhalation (FBI) is an uncommon clinical entity in adults. Despite this, FBI is an under‐recognized, serious, and easily treatable condition. The authors report a case of a 31‐year‐old female asthmatic who presented with wheeze and cough not responding to therapy. Chest computed tomography and bronchoscopy confirmed a foreign body distal to the left upper lobe vestibule. The non‐organic material was removed with rigid bronchoscopy and cryoprobe with resolution of symptoms. FBI remains an important differential in those presenting with respiratory symptoms in the absence of other diagnoses.
Spontaneous remission of the micronodular pattern in cryptogenic organizing pneumonia

Published: June 2020

AbstractOrganizing pneumonia (OP) is a common interstitial lung disease, pathologically characterized by polypoid granulation tissue in the alveolar ducts and alveoli. In clinical practice, OP occasionally presents as non‐resolving pneumonia. The typical radiographic pattern of OP is characterized by dense consolidation with ground‐glass opacities. Diffuse micronodular pattern of OP (MNOP) is a rare radiographic manifestation that mimics non‐resolving bronchiolar diseases such as pulmonary tuberculosis or hypersensitivity pneumonitis. Steroid therapy is usually effective for MNOP; however, spontaneous remission in MNOP has never been reported. Herein, we report a case of a diffuse micronodular form of cryptogenic OP (COP) that was diagnosed via transbronchial biopsy (TBB) and resolved spontaneously within a few months. Our case highlights that MNOP may resolve spontaneously similar to other forms of OP, and mild cases may be under‐recognized. Furthermore, careful observation could be an option for managing MNOP with mild and non‐progressive symptoms.
A multi‐criteria sustainable supplier selection framework based on neutrosophic fuzzy data and entropy weighting

Published: June 2020

AbstractThe gains in corporate sustainability are important for business development under the increasing competition and climate change. The importance of the green and sustainable supplier selection has increased due to the environmental concerns and regulations. The information for business decisions is often vague and imprecise. Therefore, this paper develops a fuzzy methodology for sustainable supplier selection based on fuzzy information. Single‐valued neutrosophic set (SVNS) is a very popular tool for processing potentially uncertain information provided by decision‐makers. Thus, SVNS is considered as a useful extension of the existing methods in uncertain complex situations. In order to facilitate the multi‐attribute decision‐making (MADM), this paper develops a new similarity measure for the SVNSs and explores its application possibilities. For achieving the aim, a single‐valued neutrosophic (SVN) hybrid weighted similarity (SVNHWS) measure is presented to reflect degree of similarity of SVNSs more effectively. Moreover, a method based on the SVNHWS and entropy measures is constructed for handling SVN MADM problems, in which, the entropy measure is used to derive the unknown weights information of attributes. Finally, an illustrative mathematical example dealing with the sustainable supplier selection is provided. The reliability of the proposed technique is tested by means of the comparative analysis.
Taxonomy of Industry 4.0 research: Mapping scholarship and industry insights
Authors: Nazarov Dashi , Klarin Anton 
Published: June 2020

AbstractA systems perspective of an emergent field such as Industry 4.0 requires combining and analysing the entire multidisciplinary scholarship under one map. Recent developments in scientometric analysis allow researchers to carry out complex bibliometric analyses coupled with an unstructured ontological discovery made available through thematic and ensuing semantic analyses to gain a holistic outlook on the ecosystem of Industry 4.0. The state‐of‐the‐art review of the entire scholarship of Industry 4.0 demonstrates three broad clusters—the implications of automation on industry, the integration of technologies and technological advancements driving the Fourth Industrial Revolution. The scholarship output is, for the first time, compared with the leading industrial and policymaking institutional reports to highlight similarities and discrepancies. This allows to propose a previously unavailable definition of Industry 4.0, which is much needed to progress the research further. The three highly discrepant areas between academic literature and industry insights include lack of research into return on investment, lack of research involving policymaking, and the implications of technological development on the workforce, firms and countries. It is imperative to drive research into the existent, as well as the highlighted, themes in advancing the knowledge and aligning the academic scholarship with the interests of practitioners.

Published: June 2020

AbstractThe coupled effects of corrosion and earthquake action on bridges piers are investigated in this study. Starting from a literature review to collect existing corrosion models, a bridge overpass is selected to perform seismic analyses. It allows to assess the degrading seismic capacity of the bridge pier at different periods due to general and pitting corrosion. The selected bridge structure belongs to the class of motorway overpass, that is a frequently used structural system all around the world. Consequently, the development of a suitable and effective tool for an in‐depth degradation analysis of this type of system, with the identification of the most appropriate time for restoration, is of paramount importance to guarantee continuous serviceability and safety.
Entrepreneurial ecosystems in Bulgaria and Romania: A comparative analysis
Authors: Hess James P. 
Published: June 2020

AbstractThis comparative analysis examines the neighboring entrepreneurial ecosystems in Bulgaria and Romania. In transitioning from past planned economies, these countries maintain similar approaches to entrepreneurship, yet they also exhibit distinct differences. Secondary data analysis revealed that both countries maintain a highly educated workforce with high start‐up skills and similar levels of global competitiveness in growing economies, while still facing low‐risk acceptance and low opportunity perception. On the other hand, Bulgaria excels in networking, building joint venture deals, attracting investment, maintaining a stronger focus on R&D, and the ability to nurture collaboration between industries and universities, while Romania displays stronger political stability, greater ease in starting a business, a more advanced infrastructure, and easier access to credit. As these countries capture the strengths of their respective economies, both Bulgaria and Romania may one day represent powerful hubs of innovation. Organizational leaders may use this study as a comparative springboard to learn new, yet workable policies that may support entrepreneurship within their respective ecosystems.

Published: June 2020

AbstractCongenital heart disease is relatively uncommon in horses. Only three reports exist that describe a tetralogy of Fallot in adult horses. Whereas in humans the presence of congenital heart disease constitutes a risk factor for developing aortic aneurysms, their association has never been reported in horses. Here, we present a case with a large ascending aortic aneurysm as a complication of a tetralogy of Fallot in an adult mare. The mare was referred with sustained tachycardia and a 5 days history of mild intermittent colic, depression, inappetence and weight loss. Echocardiography was used to characterize the cardiac abnormalities and aortic root dilation. Due to the poor prognosis, the mare was euthanized and post‐mortem examination further characterized the abnormalities. At least four factors contributed in this case to the development of aortic haematoma: congenital disease, mucoid extracellular matrix accumulation vasa vasorum dysfunction and inflammatory/degenerative lesions in the aorta's intima. Although colic is primarily caused by gastrointestinal issues, cardiac disease should be suspected in cases with sustained tachycardia, even in absence of murmurs or arrhythmias. Despite the fact that congenital abnormalities are usually detected in foals, they may sometimes remain unnoticed for several years.
On the top rung of Jacob's ladder of density functional theory: Toward resolving the dilemma of SIE and NCE
Authors: Zhang Igor Ying , Xu Xin 
Published: June 2020

AbstractAccording to the classification of Jacob's Ladder proposed by Perdew, density functional approximations (DFAs) on the top (fifth) rung add the information of the unoccupied Kohn–Sham orbitals, which hold the promise to enter the heaven of chemical accuracy. In other words, we expect that a much higher accuracy with a broader applicability than the existing DFAs would eventually be achieved on the fifth rung. Nonetheless, Jacob's Ladder itself does not offer a recipe for how to manipulate the unoccupied Kohn–Sham orbitals on the construction of a successful fifth rung DFA. In this article, we briefly review two successful types of the fifth rung DFAs, that is, random‐phase approximation (RPA) and doubly hybrid approximation (DHA). The limitations of RPA and DHA will be introduced in the context of the so‐called self‐interaction error (SIE)/nondynamic correlation error (NCE) dilemma in the world of density functional theory. We propose the development strategy for DHAs to address the general concern about the future of advanced DFAs on the fifth rung. We share our experience here, based on the relevant efforts recently made by the authors and their co‐workers, aiming to resolve the SIE/NCE dilemma and to extend the applicability of DHAs from the chemistry of the main group elements to that of the transition metals.This article is categorized under:

Numerical study of a pendulum absorber/harvester system with a semi‐active suspension
Authors: Kecik Krzysztof 
Published: June 2020

AbstractThe paper presents numerical analysis of an absorber/harvester system installed on the semi‐active suspension. The pendulum tuned mass absorber has been modified by use of a magnetic levitation harvester. The primary goal is to mitigate the vibration of the primary structure and the secondary goal is to harvest energy out of the vibration absorber simultaneously. This system is strongly nonlinear and the unstable regions are detected. Therefore, to control the dynamic response the semi‐active suspension consisting of the magnetorheological (MR) damper and the shape memory alloy (SMA) spring is proposed. It is shown that with a proper configurations of parameters an effective energy harvesting can be obtained combined with vibration mitigation in the host system.

AbstractAlthough overall survival in diffuse large B cell lymphomas (DLBCL) has improved, central nervous system (CNS) relapse is still a fatal complication of DLBCL. For this reason, CNS prophylaxis is recommended for patients at high risk of CNS disease. However, no consensus exists on definition of high-risk patient and optimal CNS prophylaxis. Systemic high-dose methotrexate in combination with R-CHOP has been suggested as a potential prophylactic method, since methotrexate penetrates the blood-brain barrier and achieves high concentration in the CNS. In this retrospective analysis, we report treatment outcome of 95 high-risk DLBCL/FL grade 3B patients treated with R-CHOP or its derivatives with (N = 57) or without (N = 38) CNS prophylaxis. At a median follow-up time (51 months), CNS relapses were detected in twelve patients (12.6%). Ten out of twelve (83%) of CNS events were confined to CNS system only. Median overall survival after CNS relapse was 9 months. Five-year isolated CNS relapse rates were 5% in the prophylaxis group and 26% in the group without prophylaxis. These findings suggest that high-dose methotrexate-containing prophylaxis decreases the risk of CNS failure.

Published: June 2020

AbstractFinding beneficial fungi antagonistic toward nematodes is important for developing more sustainable agricultural practices. We isolated abundant fungi from cysts of the beet cyst nematode Heterodera schachtii and tested their interaction with nematodes and sugar beet. By molecular screening of fungal communities colonizing five field populations of H. schachtii using DGGE and Sanger sequencing, three strains identified as Exophiala sp., Pochonia chlamydosporia and Pyrenochaeta sp. were frequently found in infected cysts and then specifically isolated (in pure culture). The three isolates were able to re-infect the cysts and colonize the eggs of H. schachtii in vitro fulfilling Koch’s postulates. In greenhouse trials, the root weight of sugar beet plants grown in substrates inoculated with nematodes and the fungal isolates was significantly higher compared to plants inoculated with nematodes only. The number of cysts propagated on roots was lower in substrates inoculated with Pyrenochaeta sp. than those in substrates inoculated with the other two fungi. However, cyst numbers did not significantly differ from the control because the propagation rate of the nematode increased with the root weight. The proportion of infected eggs per cyst was higher under the fungal treatments than the control, and it increased with the number of propagated cysts. The results showed that the here-studied strains of Exophiala sp., Pochonia chlamydosporia and Pyrenochaeta sp. were frequently found colonizing the nematode cysts of different populations of H. schachtii and were efficient in parasitizing the eggs of the nematode.

Published: June 2020

AbstractPlastic pollution has enormous impacts on freshwater and marine ecosystem health, and it is one of the topmost environmental concerns of the current geological period (i.e. the Anthropocene). Thus, the goal of our study was to provide baseline information and bridge the information gap on the occurrence of microplastics (MPs) in African freshwater systems, using two tributaries of the Gulf of Guinea (Ogun and Osun Rivers) in Nigeria as a case study and three freshwater insect species of different feeding guilds as bioindicators. A total of 29 individuals of the insect species were chemically digested and subsequently analysed for MP presence under a digital microscope and a micro-Fourier-transform infrared (μFTIR) spectroscope. Collector-gatherers (Chironomus sp. and Siphlonurus sp.) recorded the highest MP load per gram wet weight, while the predatory Lestes viridis recorded the lowest. The highest diversity of polymers was recorded in Chironomus sp. of Ogun River, i.e. styrene ethylene butylene styrene, acrylonitrile butadiene styrene (ABS), chlorinated polyethylene, polypropylene (PP), and polyester, while two polymers each were recorded in Siphlonurus sp. (i.e. polyester and ABS) and L. viridis (i.e. polyester and PP) of Osun River. We conclude that collector-gatherers like Chironomus sp. and Siphlonurus sp. could be best employed as MP bioindicators in freshwater systems. However, their suitability as MP bioindicators should be further investigated in different freshwater ecosystems worldwide.
