A Merged Two-Dimensional Approach to Evaluating the Efficient Performance of Non-Financial Companies Listed on the Regional Securities Exchange SA (BRVM)

The objective of this research is to study the internal and external factors that explain the efficient performance of companies listed on the BRVM using a merged two-dimensional approach. Efficient performance refers to the combination of high "financial performance and stock market performance". The results of the binomial logistic regression on a panel of companies over the periods 2011 to 2020 show that only internal factors, namely the company's flexibility in terms of financial communication, its ability to increase its intrinsic performance, its debt policy and its size, have a significant effect on the efficient performance of these companies. These results could not only serve as a frame of reference for investors to make optimal decisions (maximising both return on equity and capital gains on share sales), but also influence the management style of companies seeking to improve their attractiveness and reputation on the financial markets.
Silicon Dioxide Thin Films Deposited Using Oxide Targets: Results of Atomistic Simulation

An atomistic simulation of silicon dioxide thin films deposited using oxide targets is performed. The influence of the oxide target on the deposition process is taken into account by introducing O=Si=O molecules into the flow of particles moving from the target to the substrate. The fraction of these molecules varied from 0 to 50%. It was found that the presence of O=Si=O molecules leads to film densification during a normal deposition. With a low-energy deposition, the increase in density was twice as high as with a high-energy deposition. The absolute value of the compressive stress increased with an increasing fraction of O=Si=O molecules in the flow of deposited particles at a normal, high-energy deposition. The influence of O=Si=O molecules on the structure of the glancing angle deposited films depends on the deposition angle.
Flexible females: nutritional state influences biparental cooperation in a burying beetle

Abstract In species that provide biparental care, there is a sexual conflict between parents over how much each should contribute toward caring for their joint offspring. Theoretical models for the resolution of this conflict through behavioral negotiation between parents assume that parents cannot assess their partner’s state directly but do so indirectly by monitoring their partner’s contribution. Here, we test whether parents can assess their partner’s state directly by investigating the effect of nutritional state on cooperation between parents in the burying beetle Nicrophorus vespilloides. We used a two-by-two factorial design, in which a well-fed or food-deprived female was paired with a well-fed or food-deprived male. We found that females adjusted their level of care in response to both their own nutritional state and that of their partner and that these decisions were independent of their partner’s contribution. We found no evidence that males responded directly to the nutritional state. Males instead responded indirectly based on the contribution of their partner. Our results suggest that parents are able to assess the state of their partner, in contrast to what has been assumed, and that these assessments play an important role in the mediation of sexual conflict between caring parents.
Intense Electric Fields and Electron‐Scale Substructure Within Magnetotail Flux Ropes as Revealed by the Magnetospheric Multiscale Mission

Three flux ropes associated with near‐Earth magnetotail reconnection are analyzed using Magnetospheric Multiscale observations. The flux ropes are Earthward propagating with sizes from ∼3 to 11 ion inertial lengths. Significantly different axial orientations are observed, suggesting spatiotemporal variability in the reconnection and/or flux rope dynamics. An electron‐scale vortex, associated with one of the most intense electric fields (E) in the event, is observed within one of the flux ropes. This E is predominantly perpendicular to the magnetic field (B); the electron vortex is frozen‐in with E × B drifting electrons carrying perpendicular current and causing a small‐scale magnetic enhancement. The vortex is ∼16 electron gyroradii in size perpendicular to B and potentially elongated parallel to B. The need to decouple the frozen‐in vortical motion from the surrounding plasma implies a parallel E at the structure's ends. The formation of frozen‐in electron vortices within reconnection‐generated flux ropes may have implications for particle acceleration.

Developing a New CAI Tool for RSI Interpreters’ Training: a Pilot Study

Over the past few years, new technologies in the field of Interpreting have greatly reshaped the way interpreters work, leading to a technological turn in Simultaneous Interpreting (Fantinuoli 2018), due to the increasing use of Remote Simultaneous Interpreting (RSI) and Computer Assisted Interpreting Tools (CAI tools). When there is no human boothmate, AI-based CAI-tools are becoming “artificial boothmates” (Fantinuoli 2017), which support the interpreter before and while they deliver Simultaneous Interpreting services through automatic terminology lookup, key term identification, automatic speech recognition, real-time speech transcription, and number highlighting. While a few researchers have investigated the field of Computer Assisted Interpreting, e. g. Fantinuoli (2017; 2018; 2019), Prandi (2018; 2020), Frittella (2022; 2023) and Defrancq (2020), more research into Computer Assisted Interpreting Training is needed, so that new technologies may be integrated into interpreter training and workflow, given their potential to help interpreters face this technological breakthrough. This pilot study, conducted within the IULM research project “Collaboration for translation and interpreting: tools and teaching applications ”, focuses on investigating the training of interpreting students on these new technologies in collaboration with the RSI-platform Converso Education by integrating the RSI-platform with a new CAI tool specifically developed for teaching purposes. To the best of our knowledge, this RSI-platform with CAI tool specifically developed for interpreting students based on their needs is the first of its kind.
Spatio-temporal changes in land cover in response to anthropogenic and hydrodynamic factors in Nyando wetland, Kenya

ion of waters for socio-economic development from Lake Victoria by a joint body with jurisdiction in the countries riparian to Lake Victoria such as the East African Community to ensure compliance with the “agreed curve” agreements. 9. The stakeholder institutions such as NEMA, LBDA, Ministry of Water and LVBC should take the lead in ensuring checks against over-release of Lake water for hydropower production and measures for sustainable land and water management not only in the Nyando Wetland study area but also in the entire basin. 10. Finally, the combination of remote sensing, GIS and socio-ecological tools in a mixed methods research is recommended as an effective approach for wetland ecosystem studies which can offer timely conservation data, even for physically inaccessible areas of the wetland. However, there is need for higher resolution imagery to improve accuracy of results for well-targeted interventions.
Is Vitamin D Deficiency a Risk Factor for Spontaneous Bacterial Peritonitis?

Background: Spontaneous bacterial peritonitis (SBP) is a severe worldwide liver condition. Objective: The aim of this study was investigating the association between serum 25(OH)D deficiency and the complications of hepatitis c virus (HCV) related cirrhosis, notably, SBP. Patients and Methods: This prospective case control study was carried out on 100 patients, with cirrhosis and ascites. The patients were divided into two groups: Group I cirrhotic patients with ascites and SBP, which were divided into two equal subgroups according to addition of 25(OH)D to treatment of SBP: group Ia did not receive vitamin D and group Ib received vitamin D. Group II: cirrhotic patients with simple ascites and without SBP. Group Ib of patients were receiving a dose of 2.000 I. U of 25 hydroxycholecalciferol per day for at least 1 week. Results: There was a significant correlation between serum vitamin D and end-stage liver disease (MELD) score (r = - 0.51, P= 0.012; r = -0.37, P= 0.016, respectively) in subgroup (GI a) not receiving vitamin D and control group. Serum level of vitamin D was also significantly correlated with ascitic polymorphonuclear neutrophils (PMN) count (cell/µL) in both SBP subgroups (GI a and b) (r = -0.61, P= 0.002; r = -0.61, P= 0.002, respectively). The receiver operating characteristic (ROC) curve analysis estimated a sensitivity of 78.3%, a specificity of 69.0%, a positive predictive value (PPV) of 58%, a negative predictive value (NPV) of 85.3% and an accuracy of 73.7% at the best cutoff value of ≤13.96 (ng/mL). The AUC was 0.76 with a highly significant P-value < 0.001. A positive highly significant correlation between serum vitamin D and serum albumin was observed in both subgroups and control (r = 0.67, P = 0.001 and r =0.50, P=0.014, r = 0.44, P=0.004, respectively). Conclusions: MELD scores >15 were related with an increased risk of SBP. It was also shown that Escherichia coli and Staph aureus were the most frequent bacteria among SBP patients.
Fundamental analysis of the firm on stock returns in the uncertainty caused by the COVID-19 pandemic: The case of emerging economy

This paper refers to a previous study of Barua (2020), which shows the impact of the pandemic on aggregate demand and supply. The novelty and the purpose of this study is to examine the fundamental impact arising from the uncertainties created by the COVID-19 pandemic caused by the Indonesian government restrictions policy (spectrum) on stock returns of the sample companies listed on the Indonesia Stock Exchange (IDX) with a minimum of 200 trading days in 2020 from 2016 to 2020. This study used multiple regression analysis and cross-sectional for the cumulative abnormal return (CAR). The result shows that the fundamentals tested had no significant effect on cumulative abnormal returns. On the other hand, only the current ratio showed a significant effect on Spectrum 1 and 4; Spectrum 1 had a positive effect while Spectrum 4 had a negative effect, and the debt service coverage ratio (DSCR) had a slightly significant effect on Spectrum 1. The study results indicate that each spectrum had different levels of uncertainty, which gave rise to different perspectives for each investor. This study provides a perspective for investors to see different levels of uncertainty on the current ratio (CR) and DSCR as determinants of fundamentals for investment consideration.
Network Topology-aware Mitigation of Undetectable PMU Time Synchronization Attacks

—Time Synchronization attacks constitute a major threat to PMU-based smart grid applications, their cost-efficient detection and mitigation is thus of utmost importance. In this paper we propose a mitigation approach based on authenticated network-based time synchronization. Our approach relies on the observation that a time synchronization attack can be undetectable if and only if it targets at least three time references in the power system, and such attacks need to be mitigated through appropriate security controls. We first provide a formal proof of this result, including a characterization of the degrees of freedom of the attacker in constructing an attack. We then formulate the problem of mitigating undetectable attacks at minimum cost as an integer linear program, and prove that it is NP-hard. To solve the problem, we propose two approximation algorithms based on (1) computing shortest paths, and (2) solving a linear relaxation of the problem. Extensive simulations suggest the superiority of the proposed algorithms on IEEE benchmark power system graphs compared to baseline solutions. We report mitigation cost savings of at least 76% compared to a naive approach for mitigation and at least 30% compared the state-of-the-art.
Assessment of Surface Water Physicochemical Variables and Macrophytes Diversity in Sokoto and Rima Rivers, Nigeria

The Sokoto and Rima Rivers are vital water bodies in Nigeria, supporting local ecosystems and communities. This study aimed to investigate various physical and chemical parameters of the water, as well as the diversity of macrophytes present in the Sokoto and Rima Rivers. Standard methods of determining physicochemical parameters and surveys of macrophytes were adopted. Results obtained revealed that temperature and depth were found to be the most influential factors on macrophytes distribution. In Sokoto River, average temperature ranged from 27.00℃ to 27.30℃, and average depth from 285 to 295 meters at both stations A and B. In Rima River, average temperature varied from 25.85℃ to 26.50℃, and average depth ranged from 730 to 735 meters at both stations A and B. Emergent species were dominant among the 20 identified macrophyte species, with 18 species, while free-floating and submerged species each represented one species. This research contributes to understanding the ecological health of the Sokoto and Rima Rivers, guiding conservation efforts, informing water resource management, and identifying potential impacts on human activities in these areas. Ultimately, the goal is to support sustainable development and protect these valuable natural resources for the long term.
Analysis of the Effect of Service Quality Dimensions, Perceived Value, and Trust on Customers of Delivery Services through E-commerce

The objective of this study was to examine the value of the influence of service quality dimensions, customer perceptions and beliefs on satisfaction in using delivery services. This research was conducted on selected shipping services via e-commerce in Indonesia with a total of 389 respondents. The novelty of this research lay in the social and economic conditions when the COVID-19 pandemic was still ongoing and according to government policies or calls for people to stay at home. This study concluded that the dimensions of assurance and empathy had a positive and significant effect directly and indirectly through trust on customer satisfaction, the tangible dimension only influenced customer satisfaction indirectly through trust. Meanwhile, the other two dimensions of service quality, namely responsiveness and reliability, did not affect customer satisfaction either directly or indirectly through trust. Trust could also mediate between the relationship between perceived value and customer satisfaction. It could be seen that it had an original sample value of 0.161 and a Pvalue of 0.000, which was smaller than 0.05.
The Binding of the SARS-CoV-2 Spike Protein to Platelet Factor 4: A Proposed Mechanism for the Generation of Pathogenic Antibodies

Pathogenic platelet factor 4 (PF4) antibodies contributed to the abnormal coagulation profiles in COVID-19 and vaccinated patients. However, the mechanism of what triggers the body to produce these antibodies has not yet been clarified. Similar patterns and many comparable features between the COVID-19 virus and heparin-induced thrombocytopenia (HIT) have been reported. Previously, we identified a new mechanism of autoimmunity in HIT in which PF4-antibodies self-clustered PF4 and exposed binding epitopes for other pathogenic PF4/eparin antibodies. Here, we first proved that the SARS-CoV-2 spike protein (SP) also binds to PF4. The binding was evidenced by the increase in mass and optical intensity as observed through quartz crystal microbalance and immunosorbent assay, while the switching of the surface zeta potential caused by protein interactions and binding affinity of PF4-SP were evaluated by dynamic light scattering and isothermal spectral shift analysis. Based on our results, we proposed a mechanism for the generation of PF4 antibodies in COVID-19 patients. We further validated the changes in zeta potential and interaction affinity between PF4 and SP and found that their binding mechanism differs from ACE2–SP binding. Importantly, the PF4/SP complexes facilitate the binding of anti-PF4/Heparin antibodies. Our findings offer a fresh perspective on PF4 engagement with the SARS-CoV-2 SP, illuminating the role of PF4/SP complexes in severe thrombotic events.
Comparative Study of Pollen Morphology and Exine Ultrastructure in Tetrads, Octads and Polyads of the Genus Mimosa (Leguminosae)

ABSTRACT This is the first study of exine ultrastructure to be performed in five endemic Mexican Mimosa taxa (M. pringlei var. pringlei, M. calcicola, M. spirocarpa, M. caerulea and M. sousae), one occurring in Mexico and Central America (M. occidentalis), one widely distributed throughout the neotropics (M. setosa var. paludosa), and two in South America (M. irrigua and M. daleoides). Mimosa pollen grains are associated in polyads (12 grains), octads and tetrads. Polyads and octads in members of the basal clade of Mimosa phylogeny (sect. Mimadenia) evince the affinity of Mimosa with Piptadenia. Octads are retained in sect. Batocaulon and tetrads are evolved in this section. More recent clades (sect. Habbasia, Mimosa and Calothamnos) only show tetrads varying in size and shape. Polyads show greater variation in the exine layers, with a bistratified granular structure. Octads display a columellar-granular infratectal structure while tetrads in sect. Mimosa exhibit a less variable exine with a granular infratectal structure.
THE EFFECT OF SEWAGE SLUDGE ON AND CUP PLANT’S (SILPHIUM PERFOLIATUM L.) BIOMASS PRODUCTIVITY UNDER WESTERN LITHUANIA’S RETISOL

The long-term field experiment with new high yielding perennial energy crop - cup plant ( Silphium perfoliatum L.) was conducted in order to evaluate its biomass productivity in Vėžaiciai branch of the Lithuanian Research Centre for Agricultural and Forestry. Experimental site – naturally acid Bathygleic Dystric Glossic Retisol, pH 4.2-4.4. Granulated sewage sludge was applied (at 45 and 90 t ha -1 rates) as an alternative organic fertilizer. The fertilization was done at the beginning of the experiment, prior to cup plant’s sprouts planting in 2013. Each experimental year, traditional N 60 P 60 K 60 fertilization was performed in a separate treatment. Cup plant’s biomass was harvesting once per season at the end of vegetation. Cup plant’s dry mass (DM) yield substantially increased from 2.80 t ha -1 (in 2014) to 13.41 t ha -1 (in 2016). The use of sewage sludge fertilization was notably superior to that of mineral fertilization for cup plant’s biomass productivity. In all experimental years, the optimal was the application of 45 t ha -1 rate of sewage sludge - in compare with unfertilized treatment (control), DM yield increased by 66 %, on average. Increasing of sewage sludge rate up to 90 kg ha -1 did not give any DM yield supplement. Energy evaluation of growing technology revealed that the application of 45 t ha -1 sewage sludge rate caused the substantial increase of energy output from 1 ha; and on the contrarily, sharply decreased net energy ratio. In order to determine the long-term effects of fertilization on biomass yield, these studies will continue a few more years.

The Distributions of Iron Average Charge States in Small Flux Ropes in Interplanetary Space: Clues to Their Twisted Structures

Small flux ropes (SFRs) have been studied for decades, but their source regions and formation mechanisms are still under debate. In this study, we focus on the formation mechanism of the twisted structures of SFRs. Current research on magnetic clouds suggests five‐type distributions of the time structure of iron average charge states (Q), which imply different formation mechanisms of twisted structures. We use a similar method to identify the Q types of 25 SFRs. However, only four of these five types of distributions are found among these SFRs. Because different origins of SFRs are characteristically affecting the formation of Q types, the possible source regions of these SFRs are distinguished. With additional compositional parameters, SFRs are reconfirmed to originate from two types of source regions: the solar corona and the interplanetary medium. Based on these results, our analysis indicates that the twisted structures of SFRs originating from the solar corona may be formed predominately during eruptions. SFRs originating from interplanetary space are related to complex magnetic reconnection processes, which may result in intricate Q distributions due to the reconstruction of magnetic field topology.

Characterization of Volatile Flavor Compounds and Aroma Active Components in Button Mushroom (Agaricus bisporus) across Various Cooking Methods

To investigate the impact of various cooking methods on the volatile aroma compounds of button mushroom, gas chromatography-mass spectrometry (GC-MS) and electronic nose (E-nose) were utilized for aroma analysis. The results indicated that the E-nose was able to effectively distinguish between the samples prepared using different cooking methods. In the raw, steamed, boiled and baked samples, 37, 23, 33 and 35 volatiles were detected, respectively. The roasting process significantly contributed to the production of flavor compounds, giving button mushroom its distinctive flavor. Sixteen differential aromas were identified based on the p-value and VIP value. Additionally, the cluster analysis of differential aroma substances revealed a stronger odor similarity between the steamed and raw groups, consistent with the results of the OPLS-DA analysis of overall aroma components. Seven key aromas were identified through OAV analysis and omission experiments. In addition, 1-octen-3-one was identified as the main aroma component of cooked button mushroom. The findings of the study can be valuable for enhancing the flavor of cooked button mushroom.
