Market Sentiment Analysis Based on Image Processing With Put-Call Volatility Gap Surface

Field: Computer Science (Physical Sciences)

Analyzing the market sentiment and forecasting movements in asset prices is extremely important and has been attempted by researchers and market practitioners. Asset volatilities, regardless of historical ones or implied from the option prices, are crucial barometers of the market. And this research proposes a new approach that combines image processing and machine learning to capture the relationships between sentiment-related features and asset movement. The proposed research is based on the tick-level SPY options transactions, and the dataset contains around 1.5 million trading records. Specially, we obtained the gap between the call surface and the put surface as the second-level implied volatility surface (IVS). After adopting the traditional convolutional neural network (CNN) to compare the predictive effects among implied volatility (IV) call surface, IV put surface, and IV gap surface, the results indicate that the IV gap provides the most significant predictability. Besides, our project creatively proposes the interframe difference approach to optimized CNN and a recurrent CNN (RCNN) to fully utilize spatial and temporal features of the IV surface data. According to experiment results, the directional accuracy of prediction ranges from 67.20% to 72.05% for asset movement forecasting at the millisecond level.
Social media marketing, shoppers' store love and loyalty

Field: Business, Management and Accounting (Social Sciences)

PurposeThis study investigates the impact of social media marketing activities (SMMA) on shoppers' store love and the impact of store love on store loyalty in grocery retail. Moreover, it explores the mediating and moderating role of store love and social media usage intensity (SMUI).Design/methodology/approachA survey was conducted among grocery shoppers and social media users in Norway. A total of 177 valid responses were collected and analyzed using partial least squares structural equation modeling (PLS-SEM).FindingsThe study discovered that SMMA impacts store love, and store love affects store loyalty. Store love serves as a mediator between SMMA and store loyalty. SMUI positively moderates the relationship between SMMA and store love; however, the relationship between store love and store loyalty is not moderated by SMUI.Research limitations/implicationsDespite having limited generalizability from a cross-sectional study, this study provides literary additions to the body of knowledge in grocery retail and enhances the cognitive appraisal theory (CAT) and the attachment theory (AT).Practical implicationsThe findings of this study will help grocery shoppers, store managers and grocery chain marketers to comprehend the role of SMMA in building emotional attachment with a grocery store and help make better decisions.Originality/valueFor the first time, this study incorporated SMUI as a moderator in the relationship between SMMA, store love and store loyalty in grocery retail. The study also proposes a new explanation for the relationship between SMMA and store loyalty by highlighting the mediating role of store love.

Traditional Medicinal Ranunculaceae Species from Romania and Their In Vitro Antioxidant, Antiproliferative, and Antiparasitic Potential

Field: Pharmacology, Toxicology and Pharmaceutics (Life Sciences)

Several Ranunculaceae species are used in folk medicine to eliminate pathologies associated with oxidative stress as well as parasitic infections; however, a number of studies confirming their pharmacological properties is limited. In this study, 19 ethanolic extracts obtained from 16 Ranunculaceae species were assayed for in vitro antioxidant, antiproliferative, and antiparasitic potential. The maximum antioxidant potential in both oxygen radical absorbance capacity (ORAC) and 2,2-diphenyl-1-picrylhydrazyl (DPPH) assays was observed for Aconitum toxicum extract [half-maximal inhibitory concentration (IC50) 18.7 and 92.6 μg/mL]. Likewise, Anemone transsilvanica extract exerted the most promising antiproliferative activity against Caco-2 (IC50 46.9 μg/mL) and HT29 (IC50 70.2 μg/mL) cell lines in 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. Additionally, a dual antioxidant and cytotoxicity effect was demonstrated for Aconitum moldavicum and Caltha palustris extracts. Whilst the efficacy of extracts was modest against Trypanosoma brucei (IC50 ranging from 88.8 to 269.3 µg/mL), several extracts exhibited high potency against Leishmania infantum promastigotes (Aconitum vulparia IC50 18.8 µg/mL). We also tested them against the clinically relevant intracellular stage and found extract of A. vulparia to be the most effective (IC50 29.0 ± 1.1 µg/mL). All tested extracts showed no or low toxicity against FHs 74Int normal cell line (IC50 ranging from 152.9 to >512 µg/mL). In conclusion, we suggest the above-mentioned plant extracts as potential candidates for development of novel plant-based antioxidant and/or antiproliferative and/or antileishmanial compounds.
STRUCTURE-PROPERTY RELATIONSHIPS OF ETHYLENE/1 -OCTENE AND ETHYLENE/1-BUTENE COPOLYMERS MADE USING INSITE TECHNOLOGY

Field: Materials Science (Physical Sciences)

The structure-property relationships of homogeneous ethylene/1-butene copolymers made using INSITE * Technology-also called constrained geometry catalyst technology (CGCT)-are explored and compared with Dow’s current AFFINITY * polyolefin elastomers, which are ethylene/1-octene copolymers. The well defined molecular architecture of these copolymers allows one to explore the comonomer effect with greater precision. The preformance of ethylene/butene and ethylene/octene copolymers with densities of 0.91 and 0.92 g/cc are emphasized. Ethylene/1-octene copolymers produced by CGCT have improved tear, impact and tensile properties, relative to ethylene/1-butene copolymers produced by CGCT. These improved physical properties were observed in both compression molded plaques and blown film samples. This study confirms the general trend of improved physical properties with increasing α-olefin branch length.
Cyclic Lipopeptide Biosynthetic Genes and Products, and Inhibitory Activity of Plant- Associated Bacillus against Phytopathogenic Bacteria

Field: Agricultural and Biological Sciences (Life Sciences)

The antibacterial activity against bacterial plant pathogens and its relationships with the presence of the cyclic lipopeptide (cLP) biosynthetic genes ituC (iturin), bmyB (bacillomycin), fenD (fengycin) and srfAA (surfactin), and their corresponding antimicrobial peptide products have been studied in a collection of 64 strains of Bacillus spp. isolated from plant environments. The most frequent antimicrobial peptide (AMP) genes were bmyB, srfAAand fenD (34-50% of isolates). Most isolates (98.4%) produced surfactin isoforms, 90.6%iturins and 79.7% fengycins. The antibacterial activity was very frequent and generally intense among the collection of strains because 75% of the isolates were active against at least 6 of the 8 bacterial plant pathogens tested. Hierarchical and correspondence analysis confirmed the presence of two clearly differentiated groups. One group consisted of Bacillus strains that showed a strong antibacterial activity, presented several cLPs genes and produced several isoforms of cLPs simultaneously, mainly composed of B. subtilisand B. amyloliquefaciens, although the last one was exclusive to this group. Another group was characterized by strains with very low or none antibacterial activity, that showed one or none of the cLP genes and produced a few or none of the corresponding cLPs, and was the most heterogenous group including B. subtilis, B. licheniformis, B. megaterium, B. pumilus, B. cereusand B. thuringiensis, although the last two were exclusive to this group. This work demonstrated that the antagonistic capacity of plant-associated Bacillusagainst plant pathogenic bacteria is related to the presence of cLP genes and to the production of the corresponding cLPs, and it is mainly associated to the species B. subtilisand B. amyloliquefaciens. Our findings would help to increase the yield and efficiency of screening methods to obtain candidate strains to biocontrol agents with a mechanism of action relaying on the production of antimicrobial cLPs
Effect of Donepezil on Cognitive Disorders Due to the Selective Serotonin Reuptake Inhibitors in the Patients with Major Depressive Disorder

Field: Medicine (Health Sciences)

Introduction: Many factors cause cognitive impairment, including medication, such as selective serotonine reuptake inhibitor drugs use. On the other hand, many drugs are used in cognitive impairment therapy, including donepezil, which act by inhibiting the cholinesterase enzyme and increase brain acetylcholine. Methods: This study was a double-blind controlled randomized controlled clinical trial on the 73 numbers of 20-50 years-old patients treated with selective serotonine reuptake inhibitor drugs using Montreal Cognitive Assessment Test. They were randomly divided into two groups: placebo recipient and donepezil recipient. The Montreal Cognitive Test- reliability 92% and IC 83% - was performed two months after drug administration in both groups.The results were analyzed by Mann-Whitney, Chi-Square, T-test and has been reviewed by SPSS Inc., Chicago, IL; Version 16. Results: There was a significant difference in the Montreal Cognitive Test score before and after the intervention in the Donepezil group as the score increased. (Paired-T Test & P-Value < 0.0001). There was also a significant difference in Montreal Cognitive Test scores before and after the intervention in the placebo group (Paired-T Test & P-Value < 0.0001) as the score dropped.Conclusion: Cholinesterase inhibitors, such as donepezil, have had beneficial effects in improving cognitive impairment caused by selective serotonin reuptake inhibitor drugs compared to placebo.
Cutaneous expansion of the scalp in the treatment of burns: Techniques and result (Experience of the plastic and reconstructive surgery department of the mohamed VI University Hospital in Tangiers)

Field: Medicine (Health Sciences)

The after-effects of scalp burns are sometimes difficult to treat, and call for a variety of plastic surgery techniques, including scalp expansion. Scalp expansion enables us to restore optimal skin quality and surface area to the patient in cases where there is a loss of substance to be covered. It represents a major advance in the treatment of burns of the scalp. This work is a retrospective study of three cases who underwent skin expansion following sequelae of scalp burns in the Department of Plastic and Burn Surgery at CHU Mohamed VI in Tangier from November 2023 to November 2024. The aim of our work is to report on our department's experience with this reconstruction method, specifying the surgical procedure, and to study the results of this technique in the management of scalp burns.

Efficacy of 2-undecanol produced by Paenibacillus polymyxa KM2501-1 in controlling Meloidogyne incognita

Field: Agricultural and Biological Sciences (Life Sciences)

ABSTRACT Root-knot nematodes (RKNs) are notoriously challenging to control because of their broad host spectrum and swift proliferation. Consequently, there is an urgent need to develop safe and effective nematicides. Microorganisms and their metabolites have the potential to control RKNs safely and effectively. Paenibacillus polymyxa KM2501-1 can produce a range of volatile organic compounds (VOCs) with nematicidal activities, among which 2-undecanol is a potential biocontrol agent against Meloidogyne incognita . Nonetheless, the mechanism by which 2-undecanol prevents RKN infection in plant roots remains unclear. 2-Undecanol has many activities against M. incognita in vitro , including contact (LC 50 = 34.5 mg/L), fumigation (LC 50 = 191.6 mg/L), attraction, locomotion inhibition (frequency of head thrash and body bend reduced by 84.0% and 97.0% at concentration of 40 mg/L) and egg hatching inhibition (by 98.5% at concentration of 80 mg/L). Upon treatment with 2-undecanol, a noticeable reduction in the number of galls was observed, and the control efficacy reached 60.8% at the dose of 5 mg/pot. Metabolomics analysis revealed that the application of 2-undecanol significantly influenced the composition of root exudates of tomato. Among the 17 differential metabolites, the up-regulated 10-undecenal could attract and kill M. incognita J2 larvae at a concentration of 100 mg/L, and cyclohexylamine had nematicidal activity at the concentration of 1,000 mg/L. This study revealed the mechanism of 2-undecanol inducing plant roots to secrete nematicidal substances with attractant activity, effectively controlling RKNs, which could pave the way for the development of environmentally friendly and cost-effective nematicides. IMPORTANCE Root-knot nematodes (RKNs) pose a formidable challenge in management due to their extensive host range and rapid reproductive capacity. Microorganisms and their metabolites hold the promise of safely and effectively controlling RKNs. 2-Undecanol, produced by Paenibacillus polymyxa KM2501-1, is a potential biocontrol agent against Meloidogyne incognita . However, the mechanism of how 2-undecanol prevents RKN infection in plant roots remains unclear. We further revealed the increase in the abundance of root exudates with nematode-attractive and nematocidal activity induced by 2-undecanol in plants. This study highlights the important role of 2-undecanol produced by P. polymyxa KM2501-1 against nematodes, which lays a theoretical foundation for the development of P. polymyxa KM2501-1 as a new microbial nematicide while 2-undecanol is a new microbial-derived nematicide.
Animal Models—Decoding the Molecular Biology of Oral Cancer

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

Animal models have long been used to understand the initiation and progression of carcinogenesis, including that of oral mucosa.(1) One of the earliest models used was the chemical-induced oral cancer model, among which the Syrian Hamster check pouch was preferred for its ideal anatomical location and physiological features.(2) Salley et al(3) demonstrated that the cheek pouch mucosa underwent gradual changes from hyperplasia, carcinoma in situ to squamous cell carcinoma when exposed to polycyclic hydrocarbon 9, 10 dimethyl-1,2, benzanthracene (DMBA). Morris(4) standardized the dosage of carcinogen to 0.5% solution of DMBA in acetone and established that 5-week old animals were ideal to induce tumor with minimum time lag and maximum yield. Lin et al(5) demonstrated the synergistic effect of arecaidine with DMBA.
Frequency of anatomic variations of radial artery in patients undergoing transradial heart catheterisation

Field: Medicine (Health Sciences)

Over the last ten years, transradial cardiac catheterisation has been increasingly applied, primarily because of its lower incidence of complications compared to the femoral approach. However, one of the greatest flaws of the transradial approach is a relatively high incidence of catheterisation failure (1-5%). Anatomic variations of the radial artery are ranked second among the reasons for this. Previous studies have not provided unambiguous data on the frequency of them. It is therefore the aim of this study to determine the frequency of anatomic variations using routine angiographies of the radial artery (RA) during the left heart catheterisation at the Interventional Cardiology Unit of the University Hospital Centre Zagreb in 2013. Seven hundred and fortynine such cardiac catheterisations were carried out during the studied period. All the images were examined and, after selection, 602 remained for further research. The process of selection required all patients to be of age and to have an accurate image of radial artery angiography. Correctly performed radial artery imaging involved the imaging of the division of the brachial artery into the ulnar and radial arteries. It also implied the visibility of at least half of the radial and half of the brachial artery. Anatomic variations are classified in accordance with the classification provided by Burzotta et al. Of the total of 602 patients, 414 (68.8%) were men and 188 were women. The youngest patient was 18 and the oldest one was 87 (mean±SD; 64±10.78), with a normal distribution of subjects across the age groups. In 538 (89.4%) of patients, cardiac catheterisation was performed through the right arm. The frequency of anatomic variations of RA was 8.8%, exclusive of tortuosities whose frequency was 12.7%. The most frequent anatomic variation was the high origin of the radial artery, found in a total of 31 (5.1%) subjects. Radioulnar loops, being one of potential contraindications for the procedure, were reported in 2% of the cases. Regression analysis revealed that age (p<0.001), female sex (p=0.015) and high origin (p=0.034) statistically significantly contributed to the development of tortuosity. The results indicate that the incidence of tortuosity increases linearly with age. Although this is not a contraindication for continuing with the procedure, we recommend that elderly patients should have angiography performed at the beginning of the procedure due to a higher frequency of tortuosity.
Surface texture processing for tribological performance improvement of UHMWPE-based water-lubricated bearings

Field: Engineering (Physical Sciences)

Purpose Water-lubricated bearings can significantly reduce the pollution to environment because the traditional oil lubricant is replaced by water in the bearings. The ultrahigh molecular weight polyethylene (UHMWPE) has proven to be effective and reliable for the manufacturing of water-lubricated bearings. However, limited work has been done to address the improvement of the tribological performance of the UHMWPE-based water-lubricated bearings using surface texture processing. This paper aims to investigate the effects of bar-grooved surface on the tribological performance improvement of UHMWPE-based water-lubricated bearings. Design/methodology/approach For the first time, the bar grooves were processed on the surfaces of UHMWPE-based water-lubricated bearings. The CBZ-1 friction and wear tester have been used to test the wear and friction performance of the bearing samples. The LI laser interference surface contour graph and the digital microscope have been used to measure the surface morphology of the specimens. The tribological characteristics of the tested bearings were analyzed. Findings With bar grooves added on the surfaces of the specimens, the friction coefficient of the specimens were lower than that of the specimens without surface texture processing; the wear quantity of the two kinds of specimens were almost the same; by using the LI laser interference surface contour graph and the digital microscope to measure the surface morphology of the specimens, the furrows of the specimens with bar grooves were narrower and shallower than that of the specimens without bar grooves. Practical implications The paper implicates that the surface texture processing using bar grooves can reduce the friction coefficient and prolong the service life of the water-lubricated bearings in practical applications. Originality/value This paper fulfills an identified need to provide important theoretical and experimental support to the design of water-lubricated bearings in practical applications.
Landscapes of Loss: The National Past in Postwar French Cinema (review)

Field: Arts and Humanities (Social Sciences)

In 1989, while participating in a seminar on the bicentennial of the French Revolution at the University of Nantes, our group visited the Vendée. Towards the end of the tour, we stopped at a small rural chapel in a quiet clearing. We had spent several class hours considering the Vendean uprisings, under the tutelage of historian Jean-Clément Martin; none of us, however, was prepared for what awaited us within. We were greeted with an overpowering floral scent, from literally hundreds of bouquets and wreaths, so densely packed that not a square inch of the altar, nor the aisle in front of it was visible. Local residents had thus commemorated those lost in massacres almost two centuries earlier, in a ritual, according to Martin, repeated in many other communities across the Vendée as an ancestral duty not to forget that stretched back to the events themselves.
