AbstractObjectives The aim of this study was to evaluate the patient’s knowledge, attitude, and practice of cross-infection control in dentistry during coronavirus diseases 2019 (COVID-19).Materials and Methods This cross-sectional observational study was conducted at Altamash Institute of Dental Medicine, Karachi from June 2020 to August 2020. A total of 775 patients participated to fill questionnaire. After scrutiny, 25 questionnaire forms were excluded due to incomplete information. Questionnaire was divided in to four sections. First section obtained patients sociodemographic information, while knowledge of patients regarding cross-infection control during COVID-19 pandemic was evaluated in second section. Similarly, the purpose of third section was to assess attitude and fourth section was designed to evaluate practice. Likert’s 3-point scale was used for registration of participant’s response. The reliability of questionnaire was assessed through Crohnbach’s α (α = 0.74). Statistical analysis was performed after entering data in to SPSS version 25. Independent t-test was used to evaluate the difference in patients’ knowledge, attitude, and practice. A p-value ≤ 0.05 was considered as statistically significant.Results Majority of the participants agreed that COVID-19 is a highly contagious disease (631, 97%) and daily screening of staff, dental assistants, dentists, and patients is necessary (568, 75.7%) along with proper sterilization of instruments and disinfection of dental operatory (650, 86.66%). A large number of participant also agreed that proper disposal of waste is utmost important for cross-infection control (601, 80.24%) and patient's waiting area should also be marked with social distancing sign (620, 82.66%). However, when asked about the common route of COVID-19 transmission in dentistry, 341 (45.5%) participants disagreed that it is not through aerosol (water droplets) generated during dental procedures.Conclusions Dental health professionals should take additional measures to educate dental patients on mechanism of potential spread of COVID-19 through the aerosols and droplets generated during dental procedures. They should also encourage the dental patients to be vigilant and question the cross-infection control measures practiced by the dentist to whom they go for dental treatment, and to decrease their chances of acquiring an infection during their visit to the dental office.

Abstract
Objective Nonimmune hydrops fetalis (NIHF) is defined as the accumulation of excess fluid in two or more body cavities in the fetus without blood incompatibility between mother and baby. We aimed to present our prenatal and postnatal management of intrauterine pleural effusions associated with NIHF.
Study Design A total of 60 patients diagnosed with NIHF with intrauterine pleural effusion were analyzed retrospectively. Gestational age of delivery or fetal demise, the intrauterine treatment procedure including extrauterine intrapartum treatment (EXIT), chest tube, and medical treatment methods in fetuses with chylothorax analyzed.
Results Thirty-nine patients (65%) were born alive between 26 and 38 weeks. A thoracoamniotic shunt was placed in one patient during the intrauterine period. Seven patients were placed bilaterally during the postnatal period, all without the umbilical cord being clamped during delivery. But 25 patients died within the first few days following birth. A total of four patients had chylothorax. Two patients who did not respond to medical treatment (somatostatin) were injected with thoracic local batticon and cured. A total of 14 patients were discharged with healing.
Conclusion Cases of progressive prenatal pleural effusions associated with NIHF have a high risk for fetal and neonatal death. We think that extreme prematurity increases postnatal mortality because it negatively affects the development of the lung and heart. A close obstetric follow-up and a multidisciplinary approach are required for the management to be selected.
Implementation Science is Imperative to the Optimization of Obstetric Care

Published: December 2020

In an effort aimed at improving outcomes, obstetric teams have enacted comprehensive care bundles and other clinical tools. Yet, these practices have had limited degrees of success on a national scale. Implementation science aims to bridge the divide between the development of evidence-based interventions and their real-world utilization. This emerging field takes into account key stakeholders at the clinician, institution, and health policy levels. Implementation science evaluates how well an intervention is or can be delivered, to whom, in which context, and how it may be up-scaled and sustained. Other medical disciplines have embraced these concepts with success. The frameworks and theories of implementation science can and should be incorporated into both obstetric research and practice. By doing so, we can increase widespread and timely adoption of evidence and further our common goal of decreasing maternal morbidity and mortality.Key Points

Published: December 2020

Abstract
Objective Orbital roof fractures are more likely to occur in younger children, specifically younger than 7 years. Cranium to face ratio decreases with age; however, there is no definition for measurement of the neurocranium or face. We propose using the length of the orbital roof as a measurement of the neurocranium and length of the orbital floor as a tool to estimate midface size. The purpose of this study is to test this measurement as a correlation rate of orbital roof fractures within the pediatric population.
Design This is a retrospective study.
Setting This study was done at the LeBonheur Children's Hospital.
Participants Sixty-six patients with orbital roof fractures were identified and stratified by gender and age, specifically younger than 7 years and 7 years or older.
Main Outcome Measures The main outcome measures were orbital roof length, floor length, and ratio thereof.
Results Mean orbital roof length was 43.4 ± 3.06 and 45.1 ± 3.94 mm for patients <7 and ≥7 years, respectively (p = 0.02). Mean orbital floor length was 41.3 ± 2.99 and 47.7 ± 4.19 for patients <7 and ≥7 years, respectively (p < 0.00001). The mean roof to floor ratio (RTFR) for patients <7 years was 1.051 ± 0.039 and for patients ≥ 7 years was 0.947 ± 0.031 (p < 0.00001).
Conclusion As children age, the relative length of the orbital roof decreases when compared with the orbital floor. The RTFR was more than 1.0 in children younger than 7 years. These differences were statistically significant when compared with children 7 years and older. This measurement shift follows the differences noted in orbital fracture patterns during childhood.
Social stigma and cultural beliefs associated with cleft lip and/or palate: parental perceptions of their experience in Kenya

Published: December 2020

AbstractCleft lip with or without cleft palate (CL/P)—a condition associated with speech, hearing, feeding, and dental problems, as well as anomalies of the bone and soft tissue around the mouth—is a common birth defect around the globe. The prevalence of this condition varies widely across different countries and regions, and is apparently highest among Asians and lowest among Africans. A review of literature reveals that there exists a dearth of information on experiences of parents of children with CL/P and stigma communication, as well as cultural beliefs associated with CL/P in Africa. To fill this gap, we conducted a descriptive qualitative study examining the experiences of parents of children with CL/P, stigma communication, and cultural beliefs associated with CL/P in Kenya. Twenty four in-depth interviews were done involving purposefully sampled parents of children born with CL/P at AIC CURE International Hospital in Nairobi, Kenya. Five overarching themes emerged under the lived experiences of parents of children with CL/P: Emotional experiences; relational experiences; burden of care and concerns; reaction by the public and friends; and source of social support. The stigma messages and beliefs associated with CL/P further exacerbated the stigma. The study revealed that stigma communication associated with CL/P remains a significant source of social and psychological anguish to parents and guardians of children with CL/P. These findings have critical implications for the management of stigma communication associated with CL/P. They point to the need for public awareness campaigns on CL/P to demystify the condition, its causes and treatment. The study shows that raising public awareness of CL/P would go a long way towards addressing the stigma associated with the condition. It underscores the need for open communication and engagement with all stakeholders to manage stigma communication associated with CL/P through culturally appropriate anti-stigma campaigns.
Boolean model for melanogenesis

Published: December 2020

Abstract
Melanogenesis is a highly regulated process through which the pigment melanin is produced in skin cells. Irregularities in the molecular events that govern the process of skin pigmentation can cause disorders like vitiligo. In order to understand the biology of disease progression, it is important to have an in depth understanding of intracellular events. Mathematical models provide an integrated view of intracellular signalling. There are very few models to date that incorporate intracellular processes relevant to melanogenesis and only one to our knowledge that simulates the dynamics of response to varying levels of input. Here, we report the formulation of the largest Boolean model (265 nodes) for melanogenesis to date. The model was built on the basis of a detailed interaction network graph published by Raghunath et al. Through additional manual curation of the reported interactions, we converted the graph into a set of Boolean rules, following the procedure of the first Boolean model (62 nodes) for melanogenesis published by Lee et al. Simulations show that the predicted response to varying UV levels for most of the nodes is similar to the predictions of the existing model. The greater complexity allows investigation of the sensitivity of melanin to additional nodes. We carried out perturbation analysis of the network through node deletion and constitutive activation to identify sensitivity of outcomes, and compared the nodes identified as sensitive to previous reports.

Abstract
The motion of a magnetic levitation structure can lead to low accuracy for magnetically suspended control moment gyros (MSCMG), artificial heart pumps or high precision stable platforms. Measuring this motion is important in orbital navigation and precision measurement technologies, but current methods are unable to measure it with high accuracy under a strong magnetic field around the magnetic levitation structure. Here, we present a method in which nitrogen–vacancy (NV) centers in diamond have been used as a sensor to detect the movement of the magnetic levitation structure. The NV quantum sensors probe the electric field around the suspension magnet induced by the magnet fluctuations. Based on the high sensitivity of 0.3 nT (√Hz)−1, the resolution of motion was about 5 nm. Also, the dynamic movement of the magnetic levitation system has been recorded in real-time with a potential resolution of ∼pm as the magnetic field sensitivity of NV center was improved to ∼pT. Our method offers a novel route to measure and feedback control the magnetic levitation system for MSCMGs in satellite attitude or for magnetic pumps in artificial heart applications.

Abstract
Substantial power dissipation in the edge plasma is required for the safe operation of ITER and next-step fusion reactors, otherwise unmitigated heat fluxes at the divertor plasma-facing components (PFCs) would easily exceed their material limits. Traditionally, such heat flux mitigation is linked to the regime of detachment, which is characterised by a significant pressure gradient between upstream and downstream scrape-off layer (SOL). However, the physics phenomena responsible for power dissipation and pressure loss are distinctly different, especially when the power dissipation is achieved by impurity seeding. In principle, it is possible to achieve substantial mitigation of the heat fluxes while maintaining conservation of the pressure along the open field lines in the SOL. This regime can be accessed by injection of medium- or high-Z impurities, which mostly radiate inside the last closed flux surface. The critical question related to such an approach is the effect on confinement and perspective fusion power generation in future thermonuclear reactors. In this work, we report on experiments at COMPASS tokamak, where neon and argon impurities were injected in ohmic or NBI-heated low confinement plasmas. With appropriate seeding waveform, stable scenarios were achieved, avoiding the radiative collapse of plasmas. Significant reduction of heat fluxes at the outer target was observed, with heat flux pattern similar to the one previously achieved by nitrogen seeding. The reduction of downstream pressure was, however, accompanied by an equal reduction of upstream pressure, indicating that the power dissipation occurred inside the separatrix. Indeed, the impurity cooling is causing a significant drop of edge temperature; however, the effect in the plasma centre is much less pronounced.

Abstract
In arctic tundra, large and small mammalian herbivores have substantial impacts on the vegetation community and consequently can affect the magnitude of carbon cycling. However, herbivores are often absent from modern carbon cycle models, partly because relatively few field studies focus on herbivore impacts on carbon cycling. Our objectives were to quantify the impact of 21 years of large herbivore and large and small herbivore exclusion on carbon cycling during peak growing season in a dry heath tundra community. When herbivores were excluded, we observed a significantly greater leaf area index as well as greater vascular plant abundance. While we did not observe significant differences in deciduous dwarf shrub abundance across treatments, evergreen dwarf shrub abundance was greater where large and small herbivores were excluded. Both foliose and fruticose lichen abundance were higher in the large herbivore, but not the small and large herbivore exclosures. Net ecosystem exchange (NEE) likewise indicated the highest carbon uptake in the exclosure treatments and lowest uptake in the control (CT), suggesting that herbivory decreased the capacity of dry heath tundra to take up carbon. Moreover, our calculated NEE for average light and temperature conditions for July 2017, when our measurements were taken, indicated that the tundra was a carbon source in CT, but was a carbon sink in both exclosure treatments, indicating removal of grazing pressure can change the carbon balance of dry heath tundra. Collectively, these findings suggest that herbivore absence can lead to changes in plant community structure of dry heath tundra that in turn can increase its capacity to take up carbon.

Abstract
Satellite-based burned area products are accurate for many regions. However, only limited assessments exist for Indonesia despite extensive burning and globally important carbon emissions. We evaluated the accuracy of four MODIS-derived (moderate resolution imaging spectroradiometer) burned area products (MCD45A1 collection 5.1, MCD64A1 (collection 5.1 and 6), FireCCI51), and their sensitivity to burned-area size and temporal window length used for detection. The products were compared to reference burned areas from SPOT 5 imagery using error matrices and linear regressions. The MCD45A1 product detected <1% of burned areas. The other products detected 38%–48% of burned area with accuracies increasing modestly (45%–57%) when smaller burns (<100 ha) were excluded, with MCD64A1 C6 performing best. Except for the MCD45 product, linear regressions showed generally good agreement in peatlands (R
2 ranging from 0.6 to 0.8) but detections were less accurate in non-peatlands (R
2 ranging from 0.2 to 0.5). Despite having higher spatial resolution, the FireCCI51 product (250 m) showed lower accuracy (OE = 0.55–0.88, CE = 0.33–0.50) than the 500 m MCD64A1 C6 product (OE = 0.43–0.79, CE = 0.36–0.51) but it was comparable to the C5.1 product (OE = 0.52–0.91, CE = 0.37–0.67). Dense clouds and smoke limited the accuracies of all burned area products, even when the temporal window for detection was lengthened. This study shows that emissions calculations based on burned area in peatlands remain highly uncertain. Given the globally significant amount of emissions from burning peatlands, specific attention is required to improve burned area mapping in these regions in order for global emissions models to accurately reflect when, where, and how much emissions are occurring.
Analysing the effect of climate policies on poverty through employment channels
Authors: Malerba Daniele , Wiebe Kirsten S 
Published: December 2020

AbstractThe recently proposed Green Deals and ‘building back better’ plans have affirmed the importance to make green transitions inclusive. This is particularly related to the labour market, which may witness significant changes. Empirically, this issue has until now received limited attention. The links between poverty and climate change are explored mainly through the lenses of climate change adaptation, or via the effects of rising energy prices on the purchasing power of poor households. We aim to address this gap by using results from a simulation of the global energy transition required to meet the 2-degree target, and compare this to a 6-degree baseline scenario. The simulation with a multi-regional input–output model finds that, overall, this transition results in a small net job increase of 0.3% globally, with cross-country heterogeneity. We complement this macro-level analysis with cross-country household data to draw implications of the effects on poverty through labour market outcomes. The few job losses will be concentrated in specific industries, while new jobs will be created in industries that currently witness relatively high in-work poverty rates, such as construction. We show that high in-work poverty in the industries of interest, and especially in middle-income countries, is often associated with low skills and an insufficient reach of social protection mechanisms. We conclude that green transitions must ensure that the jobs created are indeed decent including fair wages, adequate working conditions, sufficient social protection measures, and accessible to the vulnerable and poorest households.
An algebraic approach to discrete time integrability
Authors: Doikou Anastasia , Findlay Iain 
Published: December 2020

Abstract
We propose the systematic construction of classical and quantum two-dimensional space-time lattices primarily based on algebraic considerations, i.e. on the existence of associated r-matrices and underlying spatial and temporal classical and quantum algebras. This is a novel construction that leads to the derivation of fully discrete integrable systems governed by sets of consistent integrable non-linear space-time difference equations. To illustrate the proposed methodology, we derive two versions of the fully discrete non-linear Schrödinger type system. The first one is based on the existence of a rational r-matrix, whereas the second one is the fully discrete Ablowitz–Ladik model and is associated to a trigonometric r-matrix. The Darboux-dressing method is also applied for the first discretization scheme, mostly as a consistency check, and solitonic as well as general solutions, in terms of solutions of the fully discrete heat equation, are also derived. The quantization of the fully discrete systems is then quite natural in this context and the two-dimensional quantum lattice is thus also examined.
Contact tracing in configuration models

Published: December 2020

Abstract
Quarantining and contact tracing are popular ad hoc practices for mitigating epidemic outbreaks. However, few mathematical theories are currently available to asses the role of a network in the effectiveness of these practices. In this paper, we study how the final size of an epidemic is influenced by the procedure that combines contact tracing and quarantining on a network null model: the configuration model. Namely, we suppose that infected vertices may self-quarantine and trace their infector with a given success probability. A traced infector is, in turn, less likely to infect others. We show that the effectiveness of such tracing process strongly depends on the network structure. In contrast to previous findings, the tracing procedure is not necessarily more effective on networks with heterogeneous degrees. We also show that network clustering influences the effectiveness of the tracing process in a non-trivial way: depending on the infectiousness parameter, contact tracing on clustered networks may either be more, or less efficient than on networks without clustering.
