R2O2R Improvements Identified by United States Space Weather Forecasters

A communication deficit exists between the space weather research and forecast communities in the research‐to‐operations‐to‐research (R2O2R) pipeline. No formal, citable space exists for forecasters to communicate needs and lessons learned to the research community (O2R). This deficit was termed the “valleys of death and lost opportunities” (NRC, 2003, https://doi.org/10.17226/10658) and has resulted in advancements taking up to 20 years or more to become forecast operational. To provide this communication space, we surveyed a group of US civilian space weather forecasters on their needed improvements, use of available resources, and interactions with researchers, via a combination of questionnaire and focus group discussions. Nineteen needed improvements were identified, clustering into four categories: scientific understanding, access to data, forecast office tools, and instrumentation. Participants appeared to prefer resources with a robust data stream of high‐resolution and high‐time cadence data which suffer few technical issues. Participants want to be included in tool development more often and earlier in the process as they felt they were “seldom listened to when it comes to what [they] actually need. ”
Modeling Temperature and Precipitation in Hyderabad and Medak Using Copula

Objective: To analyze the Temperature and Precipitation dependence in Hyderabad and Medak and forecast Temperature. Hyderabad and Medak are districts of Telangana State, which is a Plateau region and Hyderabad is chosen as it is a thickly populated area whereas Medak is the nearest district to Hyderabad, which has relatively less population. Methods and Statistical analysis: The data is collected from the Indian Meteorological Department,Pune from 1901 to 2019. Data from 1901 to 1996 used for training and 1997 to 2019 data used for testing. Modeling is done keeping in view the deep association between Temperature and Precipitation, through Copula analysis. The Mean Absolute Percentage Error (MAPE) for the best model in Hyderabad and Medak are found to be 0.04 and 0.09 respectively. R- Software and IBM SPSS statistics version 25 were used to analyze the data and interpret the results. Findings: The best Copula need not be necessarily the same for different data sets. We could find the best Copula for Hyderabad as Rotated Gumbel 270 Copula and for Medak, Frank Copula based on AIC and BIC criteria. The simulated data of Temperature showed a very close agreement with testing data, which can be seen in [Figure 5 (a) & (b)]. Novelty: This type of analysis and model fitting is not found in the literature for Hyderabad and Medak and these districts are in Telangana, the Plateau region. Our fitted models can give a good prediction of Temperature in this region. Keywords: Temperature; Precipitation; Normal distribution; Rotated Gumbel 270 Copula and Frank Copula
Removal Characteristics of Sulfonamide Antibiotic Compounds in Biological Activated Carbon Process

In this study, the effects of three different biological activated carbon (BAC) materials (each coal, coconut and wood based activated carbons), empty bed contact time (EBCT) and water temperature on the removal of sulfonamide 5 species in BAC filters were investigated. Experiments were conducted at three water temperatures (5, 15 and ) and four EBCTs (5, 10, 15 and 20 min). The results indicated that coal based BAC retained more attached bacterial biomass on the surface of the activated carbon than the other BACs, increasing EBCT or increasing water temperature increased the sulfonamide 5 species removal in BAC columns. In the coal-based BAC columns, sulfachloropyridazine (SCP), sulfamethazine (SMT) and sulfathiazole (STZ) removal efficiencies were 30~80% and sulfadimethoxine (SDM), sulfamethoxazole (SMX) removal efficiencies were 18~70% for 5~20 min EBCT at . The kinetic analysis suggested a first-order reaction model for sulfonamide 5 species removal at various water temperatures (5~). The pseudo-first-order reaction rate constants and half-lives were also calculated for sulfonamide 5 species removal at 5~. The reaction rate and half-lives of sulfonamide 5 species ranging from 0.0094~0.0718 and 9.7 to 73.7 min various water temperaturs and EBCTs in this study could be used to assist water utilities in designing and operating BAC filters for sulfonamide antibiotic compounds removal.
Homoclinic Bifurcation of a Quadratic Family of Real Functions with Two Parameters

In this work the homoclinic bifurcation of the family H={h(a,b)(x)=ax2+b:a∈R/{0},b∈R} is studied. We proved that this family has a homoclinic tangency associated to x=0 of P1 for b=-2/a. Also we proved that Wu(P1) does not intersect the backward orbit of P1 for b>-2/a, but has intersection for b0. So H has this type of the bifurcation.
The Effect of Polishing Techniques on Color Change of Nanofill Composite Resin Immersed in Green Tea (Camellia sinensis)

Introduction: Nanofill composite resin with its filler particle 0.005-0.1 µm can have better polishing result so that as a restoration it is more resistant towards staining that is susceptible to occur by the exposure to food and beverage. Polishing is done to improve the color stability of composite resin. Polishing techniques can be divided into one-step technique and multi-step technique. One of the staining agents, green tea tannin can cause discoloration in composite restoration. Objective: This research determine the effect of polishing techniques on the color change of nanofill composite resin after green tea immersion. Methods: The sample used was nanofill composite resin with the diameter of 10 mm and thickness of 2 mm. Samples were divided into 2 groups, 10 samples with one-step polishing technique and 10 samples with multi-step polishing technique. Samples were soaked in distilled water for 24 hours at 37oC and initial color measurements were taken. The treatment was given by immersing the samples in green tea solution for 5x24 hours at 37°C incubator. Measurements of the samples final color after the treatment were done after the fifth day. Results: One-step and multi-step polishing techniques affect the overall color value of the nanofill composite resin after treatment. The multi-step technique group had lower overall color value than the one-step technique (p=0.00). There were significant differences in the L, C, and H values after treatment with one-step and multi-step groups (p<0.05). Conclusion: The multi-step polishing technique produced better roughness reduction with the result that less color change.
Hydrodeoxygenation of fatty acid esters catalyzed by Ni on nano-sized MFI type zeolites

The impact of support morphology and composition on the intrinsic activity of Ni supported on MFI-type zeolite was explored in the hydrodeoxygenation of methyl stearate, tristearate, and algae oil (mixture of triglycerides). The nano-sized structure of the support (self-pillared nanosheets) is beneficial for the activity of the catalysts. Higher Ni dispersion and concomitant higher reaction rates were obtained on nano-structured supports than on zeolite with conventional morphology. Rates normalized to accessible Ni atoms (TOF), however, varied little with support morphology. Acidity of the support increases the rate of Ni-catalyzed C–O hydrogenolysis per surface metal site.

Sensing Characteristics of Phosphorene Monolayers toward PH3 and AsH3 Gases upon the Introduction of Vacancy Defects

Motivated by the exceptional interest of researchers in two-dimensional nanostructures, the current study deals with the structural, electronic, optical, and gas-sensing properties of recently synthesized monolayer phosphorene. Van der Waals induced first-principles calculations were performed to study the binding mechanism of pristine and defected phosphorene towards the toxic gases PH3 and AsH3. The preferential sites and orientations of these molecules on the phosphorene sheet were determined, and a detailed analysis of the adsorption energetics was performed. Both of the gas molecules interact weakly with the phosphorene sheet, with AsH3 the binding was slightly stronger than PH3. The creation of defects such as monovacancies and divacancies in the phosphorene sheet was found to significantly enhance the adsorption mechanism. The adsorption energies of both PH3 and AsH3 improved by factors of four and three, respectively, as compared to their values on pristine phosphorene. The adsorption mechanism wa.
Benefit of Including Food-Derived Ingredients in Enteral Nutrition Formulas: Practical Experience from Clinical Cases

Recent studies would indicate that there has been an increase in the use of Blended Diet (BD) with enterally fed children. Parents report that BD has led to significant positive changes for children’s physical health and wellbeing. One study has shown that BD is well tolerated and improvements in retching and gagging were observed after commencing the diet. In 2019 the British Dietetic Association (BDA) changed their position statement on BD and now encourages an open discussion with dietitians and parents about the potential risks and benefits of BD. Commercially available formulas containing food derived ingredients have also been shown to improve symptoms of feed intolerance. A recent tolerance and acceptability study used Isosource® Junior Mix (ISJMIX); a 1.2 kcal/ ml formula with 14% food derived ingredients (Nestlé Health Science) in children aged one to fourteen with a range of medical conditions. Improved stool consistency as well decreased gagging and retching was observed in this cohort, indicating that food derived ingredients could alleviate symptoms of feed intolerance. This case study series provides and with an overview of four children aged between twenty-six months to ten years. The children have a range of conditions including learning and physical disabilities, digestive tract abnormalities and genetic conditions such as DiGeorge’s syndrome. Reflux, constipation and vomiting were among the symptoms of feed intolerance reported. Significant improvements in these symptoms were reported following a change to ISJMIX which resulted in improved quality of life for children and their families. ISJMIX could be considered as a sole source of nutrition or in conjunction with BD when children are not tolerating a standard commercial formula.

Inter-related Factors Influencing Sexual Quality of Life among Women Living with HIV in Banten Province, Indonesia: A Mixed Methods Study

Socio-cultural concerns often restrict women's sexual rights and well-being living with HIV (WLHIV) in developing countries. These convergent parallel mixed methods study combined quantitative and qualitative approaches to explore factors influencing WLHIV sexual quality of life in Banten Province, Indonesia. A 2017 cross-sectional survey of 207 reproductive-aged WLHIV was analyzed using univariate and multivariate logistic regression statistics. Furthermore, indepth interviews with a sub-sample of survey participants (n = 30) were thematically analyzed. Most of the women (60%) involved reported loss of sexual pleasure and depressed sexual life. Meanwhile, 48% affirmed low sexual quality of life which was associated with unemployment (aOR = 2.90, and 95%CI = 1.51–5.58), limited sexual activities (aOR = 2.89, and 95%CI = 1.20–6.93), living with extended family (aOR = 2.68, and 95%CI = 1.27–5.65), and experiencing intimate partner violence (aOR = 2.28, and 95%CI = 1.03–5.03). The respondents described unsatisfactory sexual life in a belief that having sex is a wife's duty and choosing not to talk about sexual issues or refuse sexual invitation in fear of triggering intimate partner violence. Inter-related personal, social, cultural, and religious factors affected the sufferers’ sexual life.
Using Transfer Learning for Diabetic Retinopathy Stages Classification

Purpose – Diabetes is a chronic disease, that leads to damage of many systems of the body. One of the dangerous complications of diabetes is diabetic retinopathy. Frequent inspection for diabetic retinopathy is essential to recognize patients at risk of visual impairment. The disease grade level must be tracked to manage its progress and to start the appropriate decision for treatment in time. Effective automated methods for the detection of diabetic retinopathy and the classification of its severity stage are necessary. It also helps to decrease the burden on ophthalmologists and reduce diagnostic contradictions among manual readers. Methods– In this research, a convolutional neural network (CNN) is used based on color retinal fundus images for the detection of diabetic retinopathy (DR) and classification of its stages. CNN can recognize sophisticated features on the retina and so provide an automatic diagnosis. The pre-trained CNN model Visual Geometry Group (VGG) is applied on DR data using a transfer learning approach to utilize the already learnt parameters based on 1,000,000 images of ImageNet with 1000 classes.Results – By conducting different experiments with different classes setting the built models achieved promising results. The best achieved accuracies for 2-ary, 3-ary, 4-ary, and 5-ary classification are 85.99, 80.5, 61.28, and 71, respectively.

Nanoscale earthquake records preserved in plagioclase microfractures from the lower continental crust

Abstract. Seismic faulting causes wall rock damage, which is driven by both mechanical and thermal stress. In the lower crust, co-seismic damage increases wall rock permeability, permits fluid infiltration and triggers metamorphic reactions that transform rock rheology. Wall rock microstructures reveal high-stress conditions near earthquake faults; however, there is limited documentation on the effects of a thermal pulse coupled with fluid infiltration. Here, we present a transmission electron microscopy study of co-seismic microfractures in plagioclase feldspar from lower crustal granulites from the Bergen Arcs, Western Norway. Focused ion beam foils are collected 1.25 mm and 1.8 cm from a 1.3 mm thick eclogite facies pseudotachylyte vein. Dislocation-free plagioclase and K-feldspar aggregates in the microfractures record a history of fluid introduction and recovery from a short-lived high-stress state caused by slip along the nearby fault. The feldspar aggregates retain the crystallographic orientation of their host and are elongated subparallel to the pseudotachylyte. We propose that plagioclase partially amorphized along the microfractures at peak stress conditions followed by repolymerization to form dislocation-free grain aggregates. Repolymerization and recrystallization were enhanced by the infiltration of fluids that transported Ca and K into the microfractures. Subsequent cooling led to exsolution of intermediate plagioclase compositions and the formation of the Bøggild–Huttenlocher intergrowth in the grains from the fracture closest to the pseudotachylyte. Our findings provide unequivocal evidence that the introduction of fluids in the microfractures occurred within the timescale of the thermal perturbation, prompting rapid annealing of damaged wall rock soon after earthquake rupture.
Key factors influencing the severity of fluvial flood hazard from tropical cyclones

Knowledge of the key drivers of the severity of river flooding from tropical cyclones (TCs) is vital for emergency preparedness and disaster risk reduction activities. This global study examines landfalling TCs in the decade from 2010 to 2019, to identify those characteristics that influence whether a storm has an increased flood hazard. The highest positive correlations are found between flood severity and the total precipitation associated with the TC. Significant negative correlations are found between flood severity and the translation speed of the TC, indicating that slower moving storms, that rain over an area for longer, tend to have higher flood severity. Larger and more intense TCs increase the likelihood of having a larger area affected by severe flooding but not its duration or magnitude, and it is found that the fluvial flood hazard can be severe in all intensity categories of TC, including those of tropical storm strength. Catchment characteristics such as antecedent soil moisture and slope also play a role in modulating flood severity, and severe flooding is more likely in cases where multiple drivers are present. The improved knowledge of the key drivers of fluvial flooding in TCs can help to inform research priorities to help with flood early warning, such as increasing the focus on translation speed in model evaluation and impact-based forecasting.

Effect of span length on the impact bending strength of poplar and pine woods

Solid wood is an important engineering material. Solid wood has superior properties, such as being renewable, easily processed, relatively inexpensive, and having higher mechanical properties relative to its density than any other engineering materials. Density, moisture content, tree species, knots, cracks, and some other variables influence the mechanical properties of wood. In this study, the effect of span length on the impact bending strength (IBS) of wood was investigated. Poplar and pine wood samples were used as test materials in the experiments. The IBS measurements were carried out following TS 2477 (1976) using a pendulum impact bending machine. Tests were conducted for various span lengths of 10, 15, 20, 25, 30, and 35 cm. The results indicated that there is a relationship between IBS and span length. The highest impact bending strength was obtained with a span length of 10 cm for poplar and pine wood. The relationship between IBS and span length was parabolic. The coefficients of determination were 0.94 and 0.99 for poplar and pine wood, respectively.
Exactly solvable Hamiltonians in quantum computing

In this paper, we investigate the problem of simulation of quantum-mechanical dynamical system with prescribed properties using of exactly solvable Hamiltonians. A method for solving time-dependent matrix Schrodinger equations in an explicit analytical form will be developed. It is based on exactly solvable time-independent problems, a certain choice of the initial conditions, and special time-dependent gauge transformations converting time-independent problems to time-dependent ones. An application of the exactly solvable time-dependent problems thus obtained to the construction of a universal set of gates for quantum computers is also presented.
