Generalized algorithm for control of numerical dispersion in explicit time-domain electromagnetic simulations

linear laser pulse in a plasma channel. We then compare the new algorithm with the standard electromagnetic update for laser-plasma accelerator stage simulations, demonstrating that by controlling numerical dispersion, the new algorithm allows more accurate simulation than is otherwise obtained. We also show that the algorithm can be used to overcome the critical but difficult challenge of consistent initialization of a relativistic particle beam and its fields in an accelerator simulation.
Evaluation of the Effect of Acute Normovolemic Hemodilution on Bleeding Rate and Short-Term Post-Operative Complication of Patient Who Underwent on-Pump Coronary Artery Bypass Graft Surgery

Email: saberikn@yahoo.com ABSTRACT Background: Efficacy of minimal acute Normovolemic Hemodilution (ANH) in avoiding homologous blood transfusion during cardiovascular surgery remains controversial. Postoperative bleeding and transfusion remain a source of morbidity and cost after open heart operations. To better understand the role of acute normovolemic hemodilution (ANH) in coronary artery bypass grafting (CABG), we compared ANH with standard intraoperative care in a retrospective cohort study. Methods: This retrospective cohort study is based on 572 patients who underwent on-pump CABG in the cardiac operating room of Imam Khomeini Hospital from June 2016 till March 2022. 221 patients (38.6%) were in the ANH group and 351 patients (61.4%) were in the control group. This study was based on patients documented information. P<0.05 was significant. Result: The prevalence of short-term complications was bleeding (74.96%), AKI (7.38%), CVA (1.92%) and HF (1.05%), respectively. In general, bleeding was more in the ANH group. There was no significant relationship between ANH and days of hospitalization in ICU (P=0.291), CVA (P=0.748), HF (P=1.000), AKI (P=0.411), bleeding rate on the second day (P=0.180), platelet transfusion (p= 0.158) and FFP transfusion (p=0.776). There was a significant relationship between ANH and the reduction of bleeding (P=0.000), the increase in bleeding on the first day (P=0.006), the reduction of mortality (P=0.007), the reduction of transfusion packed cell (p=0.000). Conclusion: It seems that ANH leads to a decrease in mortality and bleeding, and as a result, a decrease in the allogenic blood transfusions and an increase in bleeding on the first day, but it have no effect on the days of hospitalization in the ICU, CVA, HF, AKI, platelet and FFP transfusion. Therefore, ANH is an effective technique in reducing mortality and bleeding and the allogenic blood transfusion.
Regionalization and policy mobilities in comparative perspective: Composing educational assemblages in quasi-federal polities

We employ a policy assemblage, mobilities, and mutations framework to analyze the geographies that constitute and reflect educational policy circulation at the regional or supranational level in trans-regional regimes and/or quasi-federal polities such as the European Union (EU) and the Caribbean Community (CARICOM). Recognizing that policies are mobile in a fragmentary fashion as they are re/dis/assembled in specific ways, places, and purposes, we move beyond methodological nationalism and pay attention to the make-up of policies as they are in motion and the places they affect. In other words, using the trans-regional and/or quasi-federal level, we juxtapose the tensions between policy as fixed, territorial, or place-specific against the dynamic, regional, and relational policy elements. Methodologically, we use a comparative federalist lens to trace and examine the distillation, translation, and mobilization of education policy across and between quasi-federal polities. In this sense, epistemologically, we further explicate the manner in which such policy instruments move across the various interconnected units and sites composing these federal-type entities, while (re)territorializing and deterritorializing what we construe as complex educational assemblages. We show that contra to the extant literature, in Europe/EU and the Caribbean/CARICOM, movement, and mobility involves the connectivity between policymaking sites, and policies arrive at their destination in the same form as they appeared elsewhere, allowing for forms of discursive isomorphism.
Using Continuous Output Neural Nets to Estimate Pasture Biomass from Digital Photographs in Grazing Lands

Accurate estimates of pasture biomass in grazing lands are currently a time-consuming and resource-intensive task. The process generally includes physically cutting, bagging, labelling, drying, and weighing grass samples using multiple “quadrats” placed on the ground. Quadrats vary in size but are typically in the order of 0.25 m2 (i.e., 0.5 m × 0.5 m) up to 1.0 m2. Measurements from a number of harvested quadrats are then averaged to get a site estimate. This study investigated the use of photographs and ‘machine learning’ to reduce the time factor and difficulty in taking pasture biomass measurements to potentially make the estimations more accessible through the use of mobile phone cameras. A dataset was created from a pre-existing archive of quadrat photos and corresponding hand-cut pasture biomass measurements taken from a diverse range of field monitoring sites. Sites were clustered and one was held back per model for testing. The models were based on DenseNet121. Individual quadrat errors were large but more promising results were achieved when estimating the site mean pasture biomass. Another two smaller additional datasets were created post-training which were used to further assess the ensemble; they provided similar absolute errors to the original dataset, but significantly larger relative errors. The first was made from harvested quadrats, and the second was made using a pasture height meter in conjunction with a mobile phone camera. The models performed well across a variety of situations and locations but underperformed when assessed on some sites with very different vegetation. More data and refinement of the approach outlined in the paper will reduce the number of models needed and help to correct errors. These models provide a promising start, but further investigation, refinement, and data are needed before becoming a usable application.
Manifestation of Heat-Induced Valuable Dietary Nucleotide Salvage in Food Prepared from Aged Fish in Fast Protein and Metabolites Liquid Chromatography, ATP-Bioluminescence Assay, and NMR Spectra

Dietary nucleotides and nucleosides, primarily inosine monophosphate (IMP) and the adenine nucleotide pool (ANP), are widely considered as essential nutrients responsible for multiple biological functions. Food prepared from meat and fish is the main source of these substances in the human diet, and it is extremely important to implement storage and processing techniques ensuring their maximum preservation and even accumulation during maturation or conditioning. In experiments with freshly refrigerated grass carp and defrosted Alaska pollock fillets it was discovered, initially using Fast Protein and Metabolites Liquid Chromatography and the ATP-bioluminescence test, and afterwards validated by NMR spectroscopy, that heat treatment identical to conventional culinary processing in aqueous or wet media at temperatures above 62 °C leads to nucleotide salvage (recovery) in aged fish. A significant increase in the concentration of IMP, and even an emergence of ANP substances, were reliably demonstrated in fish samples which had already partially or fully lost these components during prolonged storage due to the ATP breakdown metabolic reactions. Owing to this recovery, the nutritive value of ready-to-eat food can be higher than was initially evaluated in raw products before heat treatment: an effect that should certainly be considered in practical nutrition. Moreover, it is necessary to reconsider the widely acknowledged system of indices of freshness based on nucleotides and nucleosides elaborated a long time ago for raw meat and fish products.
Removal of GDP Mandrels from Sputter-Coated Beryllium Capsules for NIF Targets

Abstract Ablative targets for the National Ignition Campaign (NIC) have been fabricated by sputter coating spherical mandrels made of glow discharge polymer (GDP) with graded copper doped beryllium (Be) layers. The inner mandrel must be completely removed to meet specific ignition design requirements. The process of removing the mandrel requires elevated temperature in the presence of oxygen. However, elevating the temperature in air also oxidizes the Be and can cause blistering on the inner surface of the Be shell. This paper will discuss a refined technique, which removes the GDP mandrel without compromising the integrity of the inner Be surface. The oxygen gradient that develops during the mandrel removal and the impact of its presence will also be discussed.
Evaluation of Awareness of General Practitioners Working in Yazd, Iran, Concerning Oral Diseases in 2015

Background: The incorporation of oral health promotion into general healthcare has been proposed by the World Health Organization. General practitioners (GPs) could play a vital role in the promotion of oral healthcare. Objectives: This study was designed to evaluate the awareness of oral and maxillofacial medicine specialty and its scope of practice among Iranian GPs. Methods: The present cross-sectional study was conducted in Yazd, Iran. A total of 95 GPs randomly filled out a close-ended questionnaire. Responses to the questionnaire were analyzed using descriptive and analytical statistics. The self-administered questionnaire comprised 35 items and covered the demographical details and characteristics of participants, in addition to their awareness of oral and maxillofacial medicine and its scope of practice. Finally, awareness scores were classified as weak, intermediate, and good. The data were analyzed using a t-test and Pearson correlation. A P-value ≤ 0.05 was considered statistically significant for all statistical analyses. Results: Only 24.2% of GPs had enough awareness. The mean score of total awareness about oral diseases was 11.82 ± 3. The mean scores of total awareness for the oral manifestations of systemic diseases, medical considerations in dentistry, and oral lesions were 3.59 ± 1.17, 3.96 ± 1.62, and 4.27 ± 1.65, respectively. Conclusions: According to this study, the awareness of GPs playing a key role regarding oral medicine and oral manifestations of systemic diseases was weak. It is recommended to revise the medical curriculum to incorporate related courses about common oral diseases into the medical curriculum. The aim will only be achieved by improving the coordination between dentists and GPs.
Measuring Johnson resistor noise in non-equilibrium conditions

In 1916, Einstein postulated the existence of gravitational waves in his General Theory of Relativity. Gravitational waves are described as ripples in the curvature of spacetime detected using laser interferometers to measure the quadrupole stretching and squeezing of space caused by these waves. Current detectors are limited by thermal noise which is calculated using the Fluctuation Dissipation Theory (FDT). A number of future detectors are planned to operate at cryogenic temperatures to reduce this thermal noise but it introduces some issues to address. The FDT relies on the system it is describing being in thermal equilibrium. For room temperature detectors, any thermal gradient present is significantly smaller than the absolute temperature and so thermal equilibrium can be assumed. In cryogenic detectors there will be substantial thermal gradients due to heat being removed through the suspension fibres and the system can no longer be seen to be in equilibrium. The experiment described in this thesis investigates the validity of the FDT when a system is in non-equilibrium. By measuring Johnson noise in a thin film platinum resistor while under the effect of a thermal gradient, the thermal noise that is predicted by the FDT can be compared with the measured thermal noise of the resistor, to look for any deviation from the theoretical values. The experiment showed a nul result where no excess noise was seen at an absolute temperature of 110k with a temperature difference of 6k across the resistor. This provides a limiting factor for the thermal gradient that will not produce excess noise above the theoretically calculated value, and giving a limit to the thermal gradient where the FDT is still valid.
Conflict and social determinants of health: would global health diplomacy resolve the Afghanistan healthcare conundrum?

ABSTRACT Public health, conflict/war, Social Determinants of Health (SDHs) and Global Health Diplomacy (GHD) are believed to be strongly interwoven. Afghanistan that is known as the ‘Graveyard of the Empire’ has been passing through a very critical phase given the prolonged civil war during the last couple of decades, wherein the ongoing current situation further pushed the country towards the collapse of the political and economic systems. Thereby, Afghanistan’s healthcare system has been entrapped into the civil war conundrum causing the SDHs to be seriously affected. Conflict in any form, i.e. local, regional, or international, has left black swan impacts on not only the SDHs but also led to health crises given the inaccessibility, unaffordability, and more of lack of the infrastructure, and exodus of trained medical staff and healthcare inequity. In this situation, it is anticipated that GHD could play a significant role in providing equitable healthcare to people at stake. Against this backdrop, the focus of this paper is; how the SDHs have been impacted by the civil conflict and how the public healthcare has been turned into a conundrum; would the GHD resolve the healthcare crisis in the prevailing scenario?
Nutritional Adequacy and Patient Perceptions of the Hospital Inpatient Haemodialysis Menu: A Mixed Methods Case Series

Aim: To evaluate the nutritional adequacy of the hospital haemodialysis menu, quantify the dietary intake of hospitalised haemodialysis patients and explore patient perceptions of the menu. Methods: The menu analysis compared the default menu to reference standards using a one sample t-test via SPSS. Eight hospitalised haemodialysis patients were purposively interviewed using semi-structured interviews. Thematic analysis was used to identify the dominant themes. The participant’s actual dietary intake was calculated and compared to individual nutrients using evidence-based guidelines. Results: Compared to the reference standards, the default inpatient haemodialysis menu did not provide adequate energy (p < 0.001, mean = 8767 kJ/day ± 362), sodium (p < 0.001, mean = 72 mmol/day ± 9), potassium (p < 0.001, mean = 64 mmol/day ± 4), vitamin C (p ≤ 0.001, mean = 33 mg/day ± 10) and fibre (p < 0.001, mean = 26 g/day ± 3). Inadequate intake of energy and protein occurred in half of the participants. Passive acceptance of the menu, environmental and cultural considerations contributed to missed food opportunities impacting the patient experience and limited intake. Conclusions: The profile of the current default inpatient haemodialysis menu impacts the dietary intake and the experience of haemodialysis inpatients. It is recommended that the default menu is optimised in line with evidence-based guidelines for inpatients.
Gender Gaps in Mode Usage, Vehicle Ownership, and Spatial Mobility When Entering Parenthood: A Life Course Perspective

Entry into parenthood is a major disruptive event to travel behavior, and gender gaps in mobility choices are often widened during parenthood. The exact timing of gender gap formation and their long-term effects on different subpopulations are less studied in the literature. Leveraging a longitudinal dataset from the 2018 WholeTraveler Study, this paper examines the effects of parenthood on a diverse set of short- to long-term outcomes related to the three hierarchical domains of mobility biography: mode choice, vehicle ownership, spatial mobility, and career decisions. The progress of the effects is evaluated over a sequential set of parenting stages and differentiated across three subpopulations. We find that individuals classified as “Have-it-alls”, who start their careers, partner up, and have children concurrently and early, significantly increase their car uses two years prior to childbirth (“nesting period”), and they then relocate to less transit-accessible areas and consequently reduce their reliance on public transportation while they have children in the household. In contrast, individuals categorized as “Couples”, who start careers and partnerships early but delay parenthood, and “Singles”, who postpone partnership and parenthood, have less pronounced changes in travel behavior throughout the parenting stages. The cohort-level effects are found to be driven primarily by women, whose career development is on average more negatively impacted by parenting events than men, regardless of their life course trajectory. Early career decisions made by women upon entering parenthood contribute to gender gaps in mid- to longer-term mobility decisions, signifying the importance of early intervention.
Unlocking the Beat: Dopamine and Eye Blink Response to Classical Music

The present study examined music-induced dopamine release, as measured by a proxy measure of spontaneous eye blinks. Specifically, we explored the effects of uplifting and sombre tones in different sections of Vivaldi’s Four Seasons to investigate the affective content of musical pieces within one composition. Seventeen participants listened to four concertos (Major modes: “Spring” and “Autumn”, Minor modes: “Summer” and “Winter”) and a silence condition while completing a three-stimulus odd-ball attention task. Electrooculograms were recorded from electrodes placed above and under the left eye. Self-reported arousal and music preference measures were also gathered during the testing session. In addition, the P3a Event-Related Potential (ERP) component was analysed as another potential index of dopamine function. Results revealed significant differences in the blink rates during music listening and silence, with the largest effect observed for the sad, melancholic “Winter” concerto. However, no significant correlation was found between blink rate and music preference or arousal. Furthermore, no reliable association was found between blink rate and the P3a ERP component, suggesting that these measures tap into different aspects of dopamine function. These findings contribute to understanding the link between dopamine and blink rate, particularly in response to classical music. Crucially, the study’s discovery that the “Winter” concerto, with its sorrowful tone, significantly increased the blink rate highlights the significance of sad music and perhaps the programmatic qualities of this concerto to induce a strong emotional response.
Near-Field Single-Scattering Calculations of Aerosols: Sensitivity Studies

We model the effects of the photosensitive parameters of aerosols on their optical properties to provide a solid framework for further experimental and theoretical studies. A spherical dust particle is used to study the effects of the ambient medium, size, surface roughness, wavelength, and imaginary part of the complex refractive index. Five Gaussian random spheres with different aspect ratios are simulated to study the dependence of aerosol light scattering properties on particle shape distribution. To investigate the influence of composition, we model two typical kaolinite-like particles (pure and composite) collected from Southwest Sahara, with 0 and 2% hematite at different mixing states. Using the method of discrete-dipole approximation in DDSCAT, a comparative study is performed with the Mueller matrix elements, scattering, absorption, extinction efficiencies, single scattering albedo, and linear depolarization ratio as indicators. For single, microscopic dust particles, near-field calculations are carried out. The results show that the intensity of backscattering and the scattering efficiency decreases in water compared to dry air. Light in the visible range is more efficient for aerosol scattering experiments. A small number of impurities in the sample will increase its absorbing properties, but, in general, the scattering efficiencies strongly depend on the single-particle mixing state. Smaller particles with a diameter comparable to the wavelength of incident light show higher scattering efficiencies but lower backscattering intensities than larger particles, while surface roughness is shown to strongly alter the polarizability of the particle but has a negligible effect on its single-scattering albedo. Moreover, different shapes have a strong effect on the degree of linear polarization, but, in general, using the spherical over elliptic shape model can underestimate the scattering efficiencies by up to 4%. Finally, variation in the imaginary part of the complex RI can underestimate the single scattering albedo by up to 35.8%.
Toward the use of LES for industrial complex geometries. Part II: Reduce the time-to-solution by using a linearised implicit time advancement

The strong increase in computational power observed during the last few years has allowed to use Large Eddy Simulation (LES) for industrial configurations. Nevertheless, the time-to-solution is still too large for a daily use in the design phases. The objective of this work is to develop a new time integration method to reduce the time-to-solution of LES of incompressible flows by allowing the use of larger time step. The projection method, probably the most commonly used method in the context of LES of incompressible flow, is generally applied using explicit time advancement which constrains the time-step value for stability reasons (CFL and Fourier constraints). The time step can then be small with respect to the physical characteristic times of the studied flow. In this case, an implicit time advancement method, which is unconditionally stable, can be used. However, this leads to non-linear resolution of momentum equation which can strongly increase time-to-solution because of non-linear iterations inside a physical iteration. To relax the stability constraints while minimising the computational cost of an iteration, a linearised implicit time advancement based on Backward Differentiation Formula (BDF) scheme is proposed in this work. The linearisation is performed using an extrapolated velocity field based on the previous fields. This time integration is first evaluated on a turbulent pipe test case. It is observed a time-to-solution up to five times lower than the explicit time integration while keeping the same accuracy in terms of mean and fluctuating velocity fields. To incorporate this new time advancement method in the automatic mesh convergence developed in Part I, a time-step control method based on the local truncation error is used. The resulting automatic time-step and mesh procedure is evaluated on a turbulent round jet case and on PRECCINSTA configuration, a swirl burner which is a representative case of an industrial aeronautical injection system. This new procedure leads to a time-to-solution up to three times lower than the previous procedure, presented in Part I.
