Improving the Arrival Time Estimates of Coronal Mass Ejections by Using Magnetohydrodynamic Ensemble Modeling, Heliospheric Imager data, and Machine Learning

Field: Physics and Astronomy (Physical Sciences)

The arrival time prediction of Coronal mass ejections (CMEs) is an area of active research. Many methods with varying levels of complexity have been developed to predict CME arrival. However, the mean absolute error (MAE) of predictions remains above 12 hours, even with the increasing complexity of methods. In this work we develop a new method for CME arrival time prediction that uses magnetohydrodynamic simulations involving data-constrained flux-rope-based CMEs, which are introduced in a data-driven solar wind background. We found that, for 6 CMEs studied in this work, the MAE in arrival time was ~8 hours. We further improved our arrival time predictions by using ensemble modeling and comparing the ensemble solutions with STEREO-A&B heliospheric imager data. This was done by using our simulations to create synthetic J-maps. A machine learning (ML) method called the lasso regression was used for this comparison. Using this approach, we could reduce the MAE to ~4 hours. Another ML method based on the neural networks (NNs) made it possible to reduce the MAE to ~5 hours for the cases when HI data from both STEREO-A&B were available. NNs are capable of providing similar MAE when only the STEREO-A data is used. Our methods also resulted in very encouraging values of standard deviation (precision) of arrival time. The methods discussed in this paper demonstrate significant improvements in the CME arrival time predictions. Our work highlights the importance of using ML techniques in combination with data-constrained magnetohydrodynamic modeling to improve space weather predictions.
An Electromyographic Analysis of Idiopathic Vocal Cord Paresis

Field: Medicine (Health Sciences)

Ten patients with idiopathic vocal cord paresis were subjected to electromyographic examination. By means of a transcutaneous approach, some 20 motor unit potentials from each vocal muscle were identified. The electromyographic pattern showed great interindividual differences. In all patients investigated it differed from the normal pattern in a way indicating a neurogenic lesion. In all muscles investigated there were changes showing that part of the motor units of the vocal muscle was subjected to denervation.
Identification and semi-quantification of polysaccharides in complex food matrices by NMR

Field: Chemistry (Physical Sciences)

Despite the extensive use of polysaccharides as food structuring ingredients, the analytical toolkit to identify and quantify these biopolymers in complex food matrices is surprisingly small. NMR has a track record in revealing the overall structure of intact polysaccharides and this encouraged us to explore its potential for analytical assessment of polysaccharides in complex food matrices. A critical first step was the isolation of polysaccharides from the food matrix. Next we optimized the experimental conditions for obtaining well resolved high-resolution NMR spectra. Within the acquired 1D and 2D heteronuclear NMR spectra mixtures of up to 4 polysaccharides of different structural classes could be resolved. By making use of spectral assignments from the literature and a home-built (1D/2D) NMR spectral library a semi-quantitative assessment of the identified polysaccharides could be made. Whereas for relatively simple compositions we could rely upon interactive 1D spectral fitting, we needed to deploy quantitative 2D NMR approaches for more complex ones. The ability of NMR to indentify and semi-quantify polysaccharides in complex food matrices makes it a complementary technique in the current toolkit for analytical assessment of polysaccharide mixtures in food matrices.
[Regulation of synthesis of virus-specific RNA in cells infected with influenza virus].

Field: Biochemistry, Genetics and Molecular Biology (Life Sciences)

Interrelationships between the level of protein synthesis and the pattern of virus-specific transcription in influenza virus-infected cells have been studied with the use of a wide range of concentrations of a protein synthesis inhibitor (cycloheximide). The obtained data reveal a predominant stimulation of the transcription for some viral genes by partial suppression of protein synthesis. The data also suggest the existence of cRNA (full transcripts) synthesis regulation, in addition to the regulation of vRNA and mRNA synthesis described earlier.
Modelling of variable density flow in karstic coastal aquifers

Field: Environmental Science (Physical Sciences)

This master thesis aims at studying the effect that the presence of the caves has on saline\nintrusion in the aquifer. Thus, the final objective is to elaborate a numerical modeling of the groundwater\nflow and salt transport in the karstic aquifer. Despite the fact that many researchers have invested their\nefforts in studying the behavior of continental karsts, the modeling examples of coastal karstic aquifers\nare very rare. Due to the complexity of the problem, it is necessary to apply drastic simplifications. In this\ncase, the karstic system has been characterized as a porous matrix crossed by one conduit. In the matrix it\nis considered that the water flow is driven by the variable density. The flow in the conduit does not take\ninto account the mass transport processes and, thus, it is supposed to be governed by the Saint Venant\nequation. This approach has not been applied to coastal aquifers previously. The main advantage of this\nmethodology is that it considers the exchange between the conduit and the surrounding matrix. In order to\nreach the objective, different models have been implemented in COMSOL Multiphysics, a Finite Element\nMethod code. Initially, the groundwater flow in the karstic system has been modeled without considering\nthe variable density of the water. Next, the variable density problem in two dimensions with and without\nthe conduit is introduced. Finally, the whole problem is extended to three dimensions.
55% PAE and High Power Ka-Band GaN HEMTs With Linearized Transconductance via $\hbox{n}+$ GaN Source Contact Ledge

Field: Engineering (Physical Sciences)

We report small- and large-signal performances of 140-nm gatelength field-plated GaN HEMTs at Ka-band frequencies, in which the GaN HEMTs were fabricated with n+ source contact ledge. The parasitic channel resistance is reduced by ~ 50%, whereas the peak extrinsic transconductance is improved by 20% from 370 to 445 mS/mm. The GaN HEMTs with n+ source ledge exhibit improvement of maximum stable gain by at least 0.7 dB over reference devices without n+ ledge. At 30 GHz, CW output power density of 10 W/mm is measured with peak PAE of 40% and associated gain of 8.4 dB at Vds = 42 V. At Vds = 30 V, the output power density is measured as 7.3 W/mm with peak PAE of 50%, peak DE of 58%, and associated gain of 8.5 dB. The best PAE was measured as 55% at 5 W/mm at 30, 33, and 36 GHz, where the associated gains were 7.9, 7.6, and 8.2 dB, respectively.
From base-rate to cumulative respect

Field: Psychology (Social Sciences)

Abstract The tendency to neglect base-rates in judgment under uncertainty may be “notorious,” as Barbey & Sloman (B&S) suggest, but it is neither inevitable (as they document; see also Koehler 1996) nor unique. Here we would like to point out another line of evidence connecting ecological rationality to dual processes, the failure of individuals to appropriately judge cumulative probability.
Viruses in type 1 diabetes

Field: Medicine (Health Sciences)

Environmental factors play an important role in the pathogenesis of type 1 diabetes and can determine if a genetically susceptible individual develops the disease. Increasing evidence suggest that among other exogenous agents certain virus infections can contribute to the beta-cell damaging process. Possible viral etiology of type 1 diabetes has been explored extensively but the final proof for causality is still lacking. Currently, the group of enteroviruses (EVs) is considered as the strongest candidate. These viruses have been found in the pancreas of type 1 diabetic patients, and epidemiological studies have shown more EV infections in diabetic patients than in controls. Prospective studies, such as the Type 1 Diabetes Prediction and Prevention (DIPP) study in Finland, are of fundamental importance in the evaluation viral effects as they can cover all stages of the beta-cell damaging process, including those preceding the initiation of the process. DIPP study has carried out the most comprehensive virological analyses ever done in prospective cohorts. This article summarizes the findings from these analyses and discuss them in the context of the existing other knowledge and the prospects for intervention studies with EV vaccines or antiviral drugs.
[Therapy of thrombocytosis in myeloproliferative syndromes using recombinant interferon-alpha-2a].

Field: Medicine (Health Sciences)

In a prospective open study 16 consecutive patients with a myeloproliferative syndrome and thrombocytosis were treated with interferon (IFN) alpha-2a. 4 patients had polycythemia vera, 4 essential thrombocythemia, 3 myeloid metaplasia and 5 chronic granulocytic leukemia. Platelet counts decreased in all treated patients within 2 to 12 weeks from a median value of 1010 x 10(9)/l to 350 x 10(9)/l. No primary or secondary resistance was observed. The initial dose of IFN was 9 m U per day. After correction of the thrombocytosis, it was progressively reduced to a minimum dose of 3 m U per week. Despite the good platelet response to IFN, leukocytosis persisted in 3 patients and polycythemia in a further 3. Side effects and poor compliance required discontinuation of therapy in 6 patients. Special attention is focused on the follow-up in 6 patients who have been treated for more than 15 months.
Bank Customer Churn Based on Different Models, Oversampling, and Encoding Methods

Field: Computer Science (Physical Sciences)

Customer churn prediction (CCP) is one of the cornerstones of Customer Relationship Management (CRM), in which one seeks to forecast whether or not a customer will quit the organization. Currently, plenty of algorithmic focuses on CCP. To fill the gap in the current study, this paper builds different models to predict bank user churn based on data from Kaggle. Specifically, we investigate the difference between models with and without oversampling, as well as discuss the difference between models under different coding methods. According to the results, ‘smote’ does not necessarily improve the performance accuracy, one hot encoding is more effective than target encoding. Finally, after all aspects of comparison, the logistic regression model is more reliable in the future analysis of customer churn of commercial banks. These results offer a guideline for future bank customer churn prediction.
Oral misoprostol versus intravaginal prostaglandin E2 for preinduction cervical ripening: a randomized trial

Field: Medicine (Health Sciences)

Objective: To compare orally administered misoprostol with intravaginal prostaglandin E2 (dinoprostone vaginal suppository) for cervical ripening and labor induction. Methods: Patients presenting with medical or obstetric indications for labor induction whose Bishop score was 6 or less were randomly allocated to receive either 50 μg of oral misoprostol or 4 mg of dinoprostone. If adequate cervical ripening or active labor did not ensue, repeat doses of each medication were administered every 4 hours. A maximum of six doses of either oral misoprostol or dinoprostone was permitted; intravenous oxytocin was subsequently administered. Results: Among the 60 enrolled patients, the mean interval from start of induction to delivery was similar between the misoprostol and dinoprostone groups (1,495 ± 119 versus 1,692 ± 242 minutes, P = 0.47). Vaginal delivery occurred within 24 hours in 46% of those administered oral misoprostol, compared with 37% of those who received dinoprostone (P = 0.5). A similar number of medication doses was administered in each group (2.6 ± 0.3 for misoprostol, 2.9 ± 0.3 for dinoprostone; P = 0.4). No statistically significant differences existed between the two groups with respect to tachysystole, uterine hyperstimulation, or fetal heart rate changes. Conclusions: Oral administration of misoprostol is an effective alternative to intravaginal prostaglandin E2 for preinduction cervical ripening.
Turning waste into resources and resources into waste: Centralised waste-to-energy nexuses and alternative modes of nexusing in Hanoi

Field: Environmental Science (Physical Sciences)

Modern infrastructure systems serve to separate urban flows of water, sewage, waste and energy. However, ideas concerning the combination of these flows to achieve resource efficiency have shaped Hanoi’s urban planning since the colonial era. Today, dominant visions of the generation of energy from waste have led to a redefinition of what is ‘waste’ that largely ignores ‘alternative modes of nexusing’, established industries of recycling operating across the city. These industries are intertwined with and overlap provincial waste management and perpetually exist beyond state-led planning and urban–rural boundaries. The case of Hanoi reveals the exclusionary and disruptive potential of predominant visions of the urban nexus, as socio-managerial conceptions obscure and potentially displace alternative modes of nexusing. We argue that opening the view to alternative modes of nexusing as part of heterogeneous infrastructures not only challenges conventional analyses of the urban nexus that exclude marginalised practices and people, but also has important policy implications for waste management and recycling in Hanoi.

Methanolic extracts of Withania somnifera leaves, fruits and roots possess antioxidant properties and antibacterial activities

Field: Pharmacology, Toxicology and Pharmaceutics (Life Sciences)

Withania somnifera, also known as ashwagandha, is an important herb in ayurvedic and indigenous medical systems. The present study was designed to evaluate the antioxidant and antibacterial activities of an 80% aqueous methanolic extract of W. somnifera roots (WSREt), fruits (WSFEt) and leaves (WSLEt).Several assays were performed to determine the antioxidant properties of this herb including 1,1-diphenyl-2-picrylhydrazyl radical (DPPH) scavenging activity, ferric reducing antioxidant power (FRAP), ferrous chelation and inhibition of β-carotene bleaching.The values for DPPH, FRAP, ferrous chelation and inhibition of β carotene bleaching for the three types of extracts ranged from 101.73-801.93 μg/ml, 2.26-3.29 mM Fe/kg, 0.22-0.65 mg/ml and 69.87-79.67%, respectively, indicating that W. somnifera, particularly the leaves, possesses significant antioxidant properties. The mean ascorbic acid content was 20.60-62.60 mg/100 g, and the mean anthocyanin content was 2.86-12.50 mg/100 g. Antibacterial activities were measured using the agar well diffusion method and five pathogenic Gram-negative bacteria: Escherichia coli, Salmonella typhi, Citrobacter freundii, Pseudomonas aeruginosa and Klebsiella pneumoniae. The leaf extracts displayed the highest activity against S. typhi (32.00 ± 0.75 mm zone of inhibition), whereas the lowest activity was against K. pneumoniae (19.00 ± 1.48 mm zone of inhibition). The lowest minimum inhibitory concentration value was 6.25 mg/ml, which was against S. typhi, followed by 12.5 mg/ml against E. coli.In addition to its antioxidant properties, W. somnifera exhibited significant antibacterial activities against Gram-negative bacteria, particularly S. typhi.
Option Pricing in a Path Integral Framework

Field: Economics, Econometrics and Finance (Social Sciences)

This dissertation is an examination of methods for computing an option price using a path integral framework. The framework, developed by Chiarella, El-Hassan and \nKucera, is based on the Black and Scholes paradigm. The path integral is backward recursive with the payoff known at expiry and has no closed form solution. Three specific financial derivatives are used in this dissertation, they are, European (call and put), American put and a down and out call (Barrier type) option. \nThe work in this dissertation examines three methods to approximate the option price. The first is a review of the spectral method offered by Chiarella et al. Their \nmethod involves the use of a Fourier-Hermite series expansion which represents the option value at each time step. The Hermite orthogonal polynomials and their associated properties are employed to create a set of recurrence relations so that a final option pricing polynomial is formed. A similar approach using normalised Hermite orthogonal polynomials is also presented. Similar methods and techniques are utilised to form a new set of recurrence relations. The accuracy obtained for both \ntypes of orthogonal polynomials are of the same magnitude.

Solvent Driving Force Ensures Fast Formation of a Persistent and Well-Separated Radical Pair in Plant Cryptochrome

Field: Biochemistry, Genetics and Molecular Biology (Life Sciences)

The photoreceptor protein cryptochrome is thought to host, upon light absorption, a radical pair that is sensitive to very weak magnetic fields, endowing migratory birds with a magnetic compass sense. The molecular mechanism that leads to formation of a stabilized, magnetic field sensitive radical pair has despite various theoretical and experimental efforts not been unambiguously identified yet. We challenge this unambiguity through a unique quantum mechanical molecular dynamics approach where we perform electron transfer dynamics simulations taking into account the motion of the protein upon the electron transfer. This approach allows us to follow the time evolution of the electron transfer in an unbiased fashion and to reveal the molecular driving force that ensures fast electron transfer in cryptochrome guaranteeing formation of a persistent radical pair suitable for magnetoreception. We argue that this unraveled molecular mechanism is a general principle inherent to all proteins of the cryptochrome/photolyase family and that cryptochromes are, therefore, tailored to potentially function as efficient chemical magnetoreceptors.
Animal Model of Dermatophytosis

Field: Veterinary (Health Sciences)

Dermatophytosis is superficial fungal infection caused by dermatophytes that invade the keratinized tissue of humans and animals. Lesions from dermatophytosis exhibit an inflammatory reaction induced to eliminate the invading fungi by using the host’s normal immune function. Many scientists have attempted to establish an experimental animal model to elucidate the pathogenesis of human dermatophytosis and evaluate drug efficacy. However, current animal models have several issues. In the present paper, we surveyed reports about the methodology of the dermatophytosis animal model for tinea corporis, tinea pedis, and tinea unguium and discussed future prospects.
Maize (Zea mays L.) cyclical populations response over diverse environments - developed via recurrent selection.

Field: Agricultural and Biological Sciences (Life Sciences)

The recurrent selection currently exists as a cyclical breeding technique that has been widely used for improvement in maize (Zea mays L.). In Pakistan maize crop is mainly grown in two seasons i.e., spring (sown during February 10 to March 10) and summer (sown during June 20 to July 20). Maize base population 'PSEV3' was developed through selfed progeny recurrent selection for three years in five consecutive crop seasons (during spring and summer - 2014 and 2015, and spring - 2016). During Summer 2017, the present study was aimed to assess the mean performance of maize improved populations C1 (based on S1 lines) and C2 (based on S2 lines) developed through selfed progeny recurrent selection, in comparison to base population (PSEV3-C0) and check genotypes (cultivars Azam and Jalal, and hybrid Kiramat) for earliness and yield traits across four environments (two each location and planting time). Genotypes, locations, and planting times exhibited significant (p≤0.01) differences for the majority of the traits. However, genotype by location, genotype by planting time, and genotype by location by planting time interactions were nonsignificant for most of the variables. By comparing with base population and check genotypes, the improved maize populations [PSEV3 (S1)-C1 and PSEV3 (S2)-C2] showed the best performance by having early maturity with increased grain yield across the locations and planting times. However, the C2 population was leading, followed by C1 as compared to the original population (C0) and check genotypes for the majority of the traits. Overall, the selfed progeny recurrent selection was found effective in improving maize base population 'PSEV3' for maturity and yield related traits.
