Abstract
The elemental carbon-to-oxygen ratio (C/O) in the atmosphere of a giant planet is a promising diagnostic of that planet’s formation history in a protoplanetary disk. Alongside efforts in the exoplanet community to measure C/O in planetary atmospheres, observational and theoretical studies of disks are increasingly focused on understanding how the gas-phase C/O varies both with radial location and between disks. This is mostly tied to the icelines of major volatile carriers such as CO and H2O. Using ALMA observations of CS and SO, we have unearthed evidence for an entirely novel type of C/O variation in the protoplanetary disk around HD 100546: an azimuthal variation from a typical, oxygen-dominated ratio (C/O  0.5) to a carbon-dominated ratio (C/O&1.0). We show that the spatial distribution and peculiar line kinematics of both CS and SO molecules can be well explained by azimuthal variations in the C/O ratio. We propose a shadowing mechanism that could lead to such a chemical dichotomy. Our results imply that tracing the formation history of giant exoplanets using their atmospheric C/O ratios will need to take into account time-dependent azimuthal C/O variations in a planet’s accretion zone.

Abstract
Scholarly work points to 5S+1, a simple yet powerful method of initiating quality in manufacturing, as one of the foundations of Lean manufacturing and the Toyota Production Systems. The 6th S, safety, is often used to prevent future occupational hazards, therefore, reducing the loss of time, money, and human resources.
This paper aims to show how Industry 4.0 technologies such as computer-based vision and object detection algorithms can help implement the 6th S in 5S+1 through monitoring and detecting workers who fail to adhere to standard safety practices such as wearing Personal Protective Equipment (PPE). The paper evaluated and analyzed three different detection approaches and compared their performance metrics. In total, seven models were proposed to perform such a task. All the proposed models utilized You-Only-Look-Once (YOLO v7) architecture to verify workers' PPE compliance. In approach I, three models were used to detect workers, safety helmets and safety vests. Then, a machine learning algorithm was used to verify if each detected worker is in PPE compliance. In approach II, the model simultaneously detects individual workers and verifies PPE compliance. In approach III, three different models were used to detect workers in the input feed. Then, a deep learning algorithm was used to verify the safety. All models were trained on Pictor-v3 dataset. It is found that the third approach, when utilizing VGG-16 algorithm, achieves the best performance, i.e., 80% F1 score, and can process 11.79 Frames per Second (FPS), making it suitable for real-time detection.

Abstract
The Rhipicephalus sanguineus sensu lato tick, (Acari Ixodidae) is considered as sanitary concern due to its role as a vector. Tick strain resistant to synthetic acaricides has caused difficulties in its control, besides synthetic acaricides are harmful to the environment and the health of other animals. The use of plants with acaricidal and repellent properties has shown promising results under laboratory conditions with characteristics that resemble an ideal acaricide/insecticide. The genus Tagetes spp. excels for its use as traditional pest control in households and plantations and also for its potential as acaricide/insecticide in laboratory conditions against R. sanguineus. The first aim of this research was to evaluate the effect of different doses of Tagetes minuta essential oil (TMEO) on the central nervous system (synganglio) in unfeed R. sanguineus adults. The synganglion histologic analysis showed a remarkable effect with signs of cell damage including volume increase, loss of shape, and vacuolization, in addition to chromatin alterations such as condensation, margination, and fragmentation. TMEO were analyzed by gas chromatography coupled with mass spectrometry showing the presence of 21 compounds that according to its chemical structure are classified as terpenoids, of these compounds (Z)-β-ocimene, o-cimene, (Z)-tagetone, and verbenona were found in major quantities. The Gas chromatography analysis showed a composition variability related to the incidence of biotic and abiotic factors.

Abstract

Within the wide diversity of fungal species of the Patagonian Andes forests, species of the genus Ramaria are some of the most attractive. Its macro and micro-morphological characters are so diverse that the species cannot be readily separated based on morphological characters alone. In Patagonia (Argentina and Chile) Ramaria has been reported associated with Nothofagaceae; however, their diversity and phylogenetic relationships are largely unknown. Currently, 18 species are reported for the region. In this study, a detailed account of Ramaria in Patagonia is presented based on an integrative analysis of phylogenetic, macro- and micro-morphological features. Internal transcribed spacer (ITS) and nuclear 28S rDNA (LSU) genes were analyzed to identify specimens from Argentina and to examine their phylogenetic relationships with other Ramaria species. The phylogenetic tree revealed that the sequences represent six Ramaria species found in Argentinian Patagonia: R. patagonica, R. botrytis, R. inedulis, R. stricta, and two new phylogenetic groups characterized as new species: R. flavinedulis and R. dendrophora. Ramaria flavinedulis produces brightly colored yellow or yellow-orange basidioma with a fused, twisted compound stipe, basidia not clamped, and basidiospores ellipsoid to cylindrical. Ramaria dendrophora exhibits pale yellow to pale rose basidioma, basidiospores ornamented with conspicuous and irregular warts. This study increased our knowledge of the phylogenetic diversity and taxonomy in Ramaria from the Patagonian Andes Forests compared with those found elsewhere.

Abstract

The daily variation of organic contaminants, both gaseous and associated with suspended particulate matter, was investigated inside the National Company of Paintings estate in Lakhdaria, Algeria. Chemical characterization of particulate matter was focused on n-alkanes, polycyclic aromatic hydrocarbons PAHs and a list of highly polar organics HPOC including phthalate esters and heterocyclic compounds, that of vapours on PAHs and polychlorobiphenyls PCBs. low molecular weight compounds were associated primarily with the gas phase (2-ring PAHs, ~ 95%; 3-ring PAHs, ~ 70%), while high molecular weight congeners were mainly associated with the particle phase (6-ring PAHs, 55%). As for PCB, concentrations (0.6 ÷ 42 ng m− 3) exceeded those reported in other Algerian and European cities. The source reconciliation of organic contaminants through principal component analysis PCA demonstrated that the principal ones were petroleum combustion, industrial manufacturing, tobacco smoking and vehicular traffic. The tobacco smoke importance was further confirmed by the analysis of PAHs diagnostic ratios. The different diagnostic ratio rates of gaseous and particulate PAHs was attributed to distinct contributions of sources such as industrial processes. The health risks for workers exposed to PAHs and PCBs in PM10 were quantitatively assessed in terms of BaP equivalent concentration (BaPeq) and the incremental lifetime cancer risk (ILCR). The ILCR associated to particulate PAHs indicated higher cancer risk for workers in the production areas, whereas that to PCBs suggested high potential health risk for laboratory workers.

Abstract
The conventional Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) state relies on the Zeeman effect of an external magnetic field to break time-reversal symmetry, forming a state of finite-momentum Cooper pairing. In superconductors with broken inversion symmetries, the Rashba or Ising-type spin-orbit coupling (SOC) can interact with either the Zeeman or the orbital effect of magnetic fields, extending the range of possible FFLO states, though evidence for these more exotic forms of FFLO pairing has been lacking. Here we report the discovery of an unconventional FFLO state induced by coupling the Ising SOC and the orbital effect in multilayer 2H-NbSe2. Transport measurements show that the translational and rotational symmetries are broken in the orbital FFLO state, providing the hallmark signatures of finite momentum cooper pairings. We establish the entire orbital FFLO phase diagram, consisting of normal metal, uniform Ising superconducting phase, and a six-fold orbital FFLO state. This study highlights an alternative route to finite-momentum superconductivity and provides a universal mechanism to prepare orbital FFLO states in similar materials with broken inversion symmetries.

Abstract
At atmospheric pressure and over the whole concentration range, densities, viscosities and refractive indices of a ternary system (tetrahydofuran + 2-propanol + 2,2,4-trimethylpentane) and three constituent binary systems at T = 298.15 K were measured. The observed values of excess volumes were obtained from the measured values of density. These findings were utilized to determine excess molar volumes (VE), viscosity variances (Δη), and refractive index deviations (Δn). The estimated values of VE, η, and n were fitted to polynomials of variable degrees (Redlich - Kister). The values estimated by several theoretical equations of prediction (Lorentz-Lorentz (L-L) relation, Flory model, Glinski model, Ramaswamy and Anbananthan (RS), and McAllister three and four-body interaction models) were compared with the ternary results (McA-3&McA-4). In conclusion, these models can help us to understand the viscosities and refractive indices of liquid mixtures. We can analyze interactions involving liquids with the use of the computed deviation quantities (VE, Δη, and Δn). These liquid mixtures' associated and non-associated processes were examined and found to be connected. When compared to non-related processes, associated processes produce a fair amount of agreement between theory and experiment.

Abstract
Owing to its difficulty in degrading and ease of accumulation in the body, perfluorooctanoic acid (PFOA) has a detrimental effect on reproduction. This study aimed to examine the effect of PFOA concentration in follicular fluid during ovulation stimulation on embryo quality and the impact of PFOA exposure on the metabolic components of follicular fluid. This was a single-center prospective study that included 25 patients with diminished ovarian reserve (DOR), 25 with normal ovarian reserve (NOR), and 25 with polycystic ovary syndrome (PCOS). Follicular fluid samples were analyzed using ultra-high performance liquid chromatography-tandem mass spectrometry. We demonstrated that the PFOA levels of follicular fluid in the DOR group were higher than those in the NOR group and PCOS group (P<0.05). PFOA concentration in the PCOS group was negatively correlated with high-quality embryos (P<0.05). To gain more insight into the impact of PFOA on the metabolic composition of follicular fluid, we classified the DOR group based on the PFOA concentration, for which metabolomic analysis was performed. In the high-concentration PFOA group, there was an increase and a decrease in three and nine metabolites, respectively, compared to that in the low-concentration group. These results suggest that PFOA may alter the metabolic composition of follicular fluid, thus, affecting ovarian reserve function.

Published: November 2022

Abstract
Background
Vaccine hesitancy is a global concern. This study was performed to understand what prevents Turkmen people from getting their third or higher COVID-19 vaccine doses.
Methods
In a qualitative content analysis study, 35 Turkmen residents of Gonbad-e Kavous city in the north of Iran who had not gotten their third or higher doses of the COVID-19 vaccine were put through semi-structured phone interviews during August and September of 2022.
Results
Analysis results determined that the following 5 category are preventing people from getting their COVID-19 vaccine booster shots: 1. Unawareness of the dangers, 2. inaccurate rumors and beliefs, 3. Negative COVID-19 vaccine experiences, 4. Vaccine effectiveness, and 5. Personal freedoms.
Conclussion:
Based on our results, interventions from multiple channels which raise awareness about the dangers of COVID-19 and the importance of booster vaccine shots are crucial. To increase the public acceptance of booster shots, healthcare policymakers must take action to raise the public's trust in vaccines and provide documented and scientific responses to the public's inaccurate rumors and beliefs.
On the Hybridization of Geometric Semantic GP with Gradient-based Optimizers
Authors: Pietropolli Gloria , Manzoni Luca , Paoletti Alessia , Castelli Mauro 
Published: November 2022

Abstract
Geometric Semantic Genetic Programming (GSGP) is a popular form of GP where the effect of crossover and mutation can be expressed as geometric operations on a semantic space. A recent study showed that GSGP can be hybridized with a standard gradient-based optimized, Adam, commonly used in training artificial neural networks.

We expand upon that work by considering more gradient-based optimizers, a deeper investigation of their parameters, how the hybridization is performed, and a more comprehensive set of benchmark problems. With the correct choice of hyperparameters, this hybridization improves the performances of GSGP and allows it to reach the same fitness values with fewer fitness evaluations.
Splitting Photon into Pair Photons to Design a High-Performance Printable Solar Cell
Authors: Hossain Md. Faruque 
Published: November 2022

Abstract
The fine silicon printable solar cell is being layered up by a very thin complex photopolymer (chloro-trifluoro-ethylene vinyl ether fluoropolymer binder and dimethacrylic perfluoropolyether oligomer) to pave forming high temperature inside the solar cell to release gamma-ray to split single photon into pair-photons. Since the conservation of photon momentum are the principal constraints for this process of breakdown of photon particle, thus, all released conserved quantum numbers (photon to electron and positron, basic kinematics, and energy transfer) are being monitored during this pair-photon production by using PerkinElmer® Lambda 25 UV/Vis Spectrometer. Subsequently, the measurement of the required photon frequency (f), and wavelength (λ) to form these pair-photons by the induction of gamma-ray has also been determined to design high-performance solar cells. The results suggested that solar cells profoundly release the gamma-ray due to the presence of photopolymer which initiates high temperature inside the solar cell and pave the photon-photon collision to produce pair-photons from a single one. Subsequently, photon to electron and positron, its basic kinematics have also been monitored during this photon-photon interaction to determine the energy transfer to design high-performance solar cells.
The Mediating Role of Perceived Instructor’s Emotional Support to Students’ Academic Resiliency and School Engagement
Authors: Lobo Joseph 
Published: November 2022

Abstract
Academic resiliency is the ability of students to cope with and overcome setbacks and chronic difficulties, specifically in the school context. Previously conducted studies have discovered that academically resilient students tend to be more engaged in academics than their counterparts. Moreover, studies have also mentioned the importance of teachers’ emotional support to students’ engagement. Concerning this, the current study is focused on determining the mediating role of perceived teachers’ emotional support (TES) in the relationship between academic resiliency (ARS) and school engagement (ENG) of students in a Higher Education Institution context in Angeles City, Philippines. A sample of 910 students (58.9% male and 41.1% female) from different institutes completed self-report questionnaires concerning academic resilience, perceived teachers’ emotional support, and school engagement. Partial Least-Square Structural Equation Modelling using SmartPLS4 was used for the mediation analysis. The results revealed that (1) academic resilience positively influences school engagement, (2) academic resilience leverages perceived teachers’ emotional support, and (3) perceived teachers’ emotional support affects school engagement. Most importantly, it was found that perceived teachers’ emotional support partially mediates the relationship between students’ academic resilience and school engagement. Based on the findings, it was emphasized the importance of teachers’ emotional support in fostering resilience and engagement with college students. Lastly, findings were discussed by stressing the importance of fostering personal and contextual resources in the college to promote students’ well-being.

Abstract

Zika virus (ZIKV) infections have been associated with severe clinical outcomes, including neurological manifestations, especially in newborns with intrauterine infection. However, no licensed vaccines or specific antiviral agents are available yet. Therefore, safe and low-cost therapy is required, especially for pregnant women. In this sense, metformin, an FDA-approved drug used to treat gestational diabetes, has previously exhibited an effect anti-ZIKA in vitro in HUVEC cells by activating AMPK. In this study, we evaluated metformin treatment duringin vitroZIKV infection in a permissive trophoblast cell line JEG3. Our results demonstrate that metformin impacts viral replication and protein synthesis and reverts the cytoskeletal changes promoted by ZIKV infection. Beyond this, lipid droplet formation is reduced, which is associated with the lipogenic activation of infection. Taken together, our findings indicate that metformin has potential as an antiviral agent against in vitro ZIKV infection in trophoblastic cells.

Abstract
This work studies, soliton solutions of time fractional coupled Konopelchenko-Dubrovsky and (3+1)-dimensional modified Korteweg-de Varies-Zakharov-Kuznestsov (mKdVZK) equations. These model are used to define the physical phenomena of oceans dynamic, plasma physics, and soliton theory. The unified method is used to solve these fractional models analytically. Conformable and Local M derivatives are used to tackle the time fractional part. Fractional wave transformation is used to transforme fractional partial differential equation to ordinary differential equation. Using proposed scheme soliton solutions are obtained in polynomial and rational forms. The behaviour of soliton solution is also analyzed at different fractional parameter. The results shows that proposed scheme is straight forward and easy to handle all kinds of time fractional nonlinear homogenous evolution equations that arised in different fields of science.

Abstract
Background: Intensive care unit (ICU) is a multidisciplinary staffed and specially equipped area of a hospital dedicated to providing quality care for patients with life-threatening conditions. The provision of intensive care services to critically ill patients is a global issue. Though care is advancing globally, the quality of available ICUs in Ethiopia is still lagging far from the standard.
Objective: This study aimed to assess ICU mortality and its associated factors among patients at Tibebe Ghion specialized hospital, Northwest Ethiopia, 2021.
Method: A retrospective cohort study was conducted from February 24th, 2019 to January 24th, 2021. Data were collected from medical records by using pretested structured data retrieval checklist. The collected data was entered into Epi-data version 3.1 and analyzed using R version 4.0 software. Descriptive statistics computed. A simple logistic analysis was run (at 95% CI and p-value < 0.05) to identify the determinants for ICU mortality.
Results: A total of 568 study participants’ charts were reviewed. The median length of ICU stay was 4 days. The overall mortality rate of the ICU-admitted patients was 29.6% (95% CI: 26%, 33%). Admitted in 2020 (AOR=0.51; 95%CI: 0.31, 0.85), having altered mentation (AOR=13.44; 95%CI: 5.77, 31.27), mechanical ventilator used (AOR = 4.11; 95%CI: 2.63, 6.43), and stayed < 5 days in the ICU (AOR = 3.74; 95%CI: 2.31, 6.06) were significantly associated with ICU mortality.
Conclusion: The ICU mortality rate was 29.6%. Years of admission, altered mentation, mechanical ventilator use and days of stay in the ICU were the predictors for ICU mortality. Improvement efforts led by the Ministry of Health with input from the acute care workforce are an urgent priority.
