Background: The study was designed to assess the role of coping style and self-esteem in the context of different phases of schizophrenia. Methods: Recurrent Schizophrenia (ReSch) , first-episode schizophrenia patients (FEP), ultra-high risk for psychosis (UHR) patients, and healthy controls (HC) (40 per group) were subjected to in-person clinical interviews. The results of these interviews were then used to gauge coping style and self-esteem using the Coping Styles Questionnaire (CSQ) and the Rosenberg’s Self-Esteem Scale (RSES). Data were analyzed through ANCOVAs and logistic regression analyses. Results: The result s found that positive coping style (CSQ problem-solving and CSQ seeking for help) generally decline with progression through the HC, UHR, and FEP groups,while negative coping style(CSQ fantasy,CSQ repression and CSQ self-blame) generally increase with progression through the HC, UHR,and FEP groups (except that UHR group was slightly lower than HC group in CSQ self-blame).Results for members of ReSch group were in line with those of members of the FEP group in coping style. At the level of self-esteem, the UHR group was similar to the HC group and significantly higher than the FEP group and the ReSch group. Logistic regression analyses indicated that UHR group patients exhibited increased negative coping styles (CSQ fantasy) relative to members of the HC group, but had greater Positive coping style (CSQ problem-solving) than did members of the FEP group. Conclusion: These findings suggest that both UHR individuals experience impaired negative coping styles which expands the understanding of the psychological characteristics of the prodromal group. Further explorations are warranted to develop optimal psychosocial interventions.

Netherton syndrome (NS) is a rare autosomal recessive genodermatosis (OMIM #256500) characterized by superficial scaling, atopic manifestations, and multisystemic complications. It is caused by loss-of-function mutations in the SPINK5 gene, which encode a key kallikrein protease inhibitor. There are two subtypes of the syndrome that differ in clinical presentation and immune

In this study, Ni/NiO catalyst has been demonstrated to enhance the hydrogen storage performance of MgH2. The dehydrogenation of MgH2+10wt% Ni/NiO started at approximately 180°C , achieving 5.83 wt% of dehydrogenation within 10 minutes at 300°C. Completely dehydrogenated MgH2 began to rehydrogenate at about 50°C, absorbing about 4.56 wt% of hydrogen in 10 minutes at 150°C. In addition, the activation energies of dehydrogenation and rehydrogenation of MgH2+10wt% Ni/NiO were 87.21 and 34.84 kJ/mol. During the dehydrogenation/rehydrogenation cycle, Mg2Ni/Mg2NiH4 could promote the diffusion of hydrogen, thus enhancing the hydrogen storage performance of Mg/MgH2.

Cooperative manipulators, vital for intricate tasks, are gaining widespread attention across industries. Recognizing their impact on power consumption, costs, and task outcomes, this paper emphasizes the critical study of control methods, actuator power consumption, and manipulator accuracy. Addressing these challenges, we propose a Neural Network-Sliding Mode Controller (NN-SMC) to optimize actuator power consumption and minimize errors in cooperative manipulators. Operating in trajectory and point-to-point modes, the NN-SMC dynamically generates real-time Switching Mode Controller (SMC) gains (L and K) for precise control. Stability is ensured by maintaining gains within permissible ranges. In point-to-point mode, the NN orchestrates an optimal path generation, along with tailored gains. To evaluate performance accurately, a novel control performance index is introduced. Experimental results on 3-DOF cooperative manipulators demonstrate a remarkable 28% increase in the control performance index for the trajectory mode and a substantial reduction in computational complexity for both modes. This work not only addresses inherent challenges in cooperative manipulators but also signifies a methodological advancement through the integration of neural network-based control, promising enhanced efficiency and stability.

An method for the electrochemical synthesis of chalcogenosulfonates via a tandem multi-component reaction has been developed. This method is performed in an undivided cell without the requirement of external oxidants, acids, and transition metals. A variety of indoles and sulfinic acid sodium salts can be used in this method, and it is effective for the late-stage modifications of complex molecules. Not only thiosulfonates and selenosulfonates but also sulfonotelluroates could be prepared, making this protocol a useful tool for the devel-opment of new functional molecules. The afforded products are promising for pesticide development.

Remote sensing has been widely applied to investigate fluvial processes, but depth retrievals face significant constraints in deep and turbid conditions. This study evaluates the potential for depth retrievals under such challenging conditions using NASA’s Airborne Visible/Infrared Imaging Spectrometer-Next Generation (AVIRIS-NG) imagery. We employ interpretable machine learning to construct a hyperspectral regressor for water depth and explore the spectral characteristics of deep and turbid waters in Wax Lake Delta (WLD), LA. The reflectance spectra of WLD show minor effects from depth differences due to turbidity. Nevertheless, a Random Forest with Recursive Feature Elimination (RF-RFE) effectively generalizes high and low turbid cases in a single model, achieving a R² of 0.94 ± 0.005. Moreover, this model shows a maximum detectable depth of approximately 30 m, outperforming other methods. A spectral analysis using Shapley additive explanations (SHAP) points out the importance of learning various spectral bands and non-linear relationships between depth and reflectance. Specifically, the short blue and Near-InfraRed (NIR) bands, with high attenuation coefficients, play a crucial role. This finding highlights the attenuation as the key process for deep-depth retrievals. The depth maps of WLD captured by this model distinctly represent the spatial distribution of deep river and shallow delta regions. However, the high dependency on short blue and NIR bands leads to discontinuous areas due to the noise sensitivity of these bands. This result highlights a drawback of remote sensing using empirical models. Future research will focus on correcting such discontinuities by integrating data from multiple remote sensing sources.

Volcanic Ash Advisory Centres (VAACs) have generated volcanic ash forecasts for the aviation industry since the mid-1990s. The excellent spatial and temporal coverage of satellite data make them critical to the validation of ash dispersion model forecasts. This study investigates the limitations of satellite-retrieved volcanic ash data through the production of simulated radiances for a range of ash cloud properties encompassing the satellite retrieval’s sensitivity. We run a detection and retrieval algorithm (Francis et al., 2012, https://doi.org/10.1029/2011JD016788) on these simulated clouds and assess the sensitivity and performance of the algorithms. Expected limitations are highlighted, including a lack of sensitivity to particles larger than ~10 µm in radius and challenges in accurately retrieving heights in the stratosphere. However, other previously poorly-defined limitations are also constrained, such as the reduction in sensitivity as ash column loading increases in optically-thick clouds and increasing underestimations for ash column loadings >~7 g m-2. We consider the implications of the identified limitations when using satellite-retrieved ash column loadings to verify dispersion model output. We show that, accounting for the limitations of the satellite retrieval, a significant proportion of mass in the model output can lie outside the sensitivity range of the satellite detection and retrieval. This demonstrates the importance of understanding observations’ limitations when comparing to model output, knowledge which should be used when verifying operational volcanic ash cloud forecasts.

Extracting a Cosmic Age of 14.6 Billion Years from All 580 Type Ia Supernova Redshifts in the                                                                        Union2 Database (first draft)                                                                            Eugene Terry Tatum                                                       Independent Researcher, Kentucky, USA                                                        https://orcid.org/0000-0002-1544-7505Abstract: Haug and Tatum have recently developed a cosmological model that links cosmic age, the Hubble constant, cosmic temperature, cosmological redshift and the Planck length in a manner fully consistent with general relativity. The original 2015 Tatum et al model, a “growing black hole” sub-class ofRH = ct models, predicted a remarkably-accurate Hubble constant value of 66.89 km/s/Mpc when inputting the 2009 Fixsen CMB temperature of 2.72548 +/- 0.00057K to their CMB temperature formula. Rearrangement of this formula also gave a cosmic age of 14.617 billion years. In the current paper, we apply the Haug and Tatum algorithm of curve-fitting cosmologic parameters to the entire Union2 type Ia supernova redshift database. In contrast to the Lambda-CDM model assertion of a 13.8 billion-year cosmic age, we find that the Union2 database matches with a cosmic age of 14.6 billion years. Thus, modern astrophysicists and astronomers have another roughly 800 million years with which to explain the “surprisingly rapid” growth of the first galaxies and their supermassive black holes.Keywords: Cosmic age, Supernova redshifts, Union2 database, Early galaxy problem, Cosmology model, RH = ctmodel, Black holes, Hubble tensionINTRODUCTION AND BACKGROUNDFor all practical purposes, the 2015 Tatum et al model of cosmology, called Flat Space Cosmology (FSC), was the first useful and highly-accurate Planck-scale quantum cosmology model [1][2][3]. Although this was not immediately apparent, the 2015 Tatum et al thermodynamic formula was key to further developments in quantum cosmology [4][5][6]. The most recent expression of this formula is the one published in the Haug and Tatum model of cosmology publication [7]. It is:                                                                                                             

The end-product concentration and productivity are critical issues in economic competition between biotechnological commercials and the chemical engineering industry. The prominent contradiction between high-titer products and the large-scale oxygen demand for aerobic biocatalysis leads to hyperviscosity, mass transport bottleneck in [dynamically changing](javascript:;) polyphase biosystems, and severe foaming problems. In this study, an intensification strategy for the whole-cell catalytic preparation of high-titer xylonic acid by Gluconobacter oxydans in a sealed-compressed oxygen supply bioreactor is propose. Multi-scale control factors are quantitatively studied to determine the biochemical parameter thresholds, and theoretically calculated the optimal production performance based on threshold effect. Finally, 650.8 g/L xylonic acid is obtained with a maximum productivity of 41.7 g/L/h with a catalytic performance of 95.8%, compared with the theoretical calculations. The intensification strategy for the oxygen transfer threshold effect overcome the stubborn obstacles of obligate aerobic catalysis, while providing a sustainable value-added pathway for fermentative lignocellulose.

Staphylococcus aureus is a common causative agent of bovine mastitis in dairy herds worldwide causing huge economic losses to the dairy industry. A cross-sectional study was conducted from July 2021 to September 2021, with the objective of isolating and identifing of S­.aureus from dairy farms in the milk samples of Bishoftu town in the Oromia region, Ethiopia. The samples were transported to a microbiology laboratory where, isolation and identification of an organism was based on morphological, cultural and biochemical characteristics, Clinical examinations, gram stain, catalase test, oxidase test and bacteriological culture methods were used as diagnostic tools to carry out the study. Accordingly, a total of 53 milk samples of where checked, 43 from teat and 10 samples from milk tankers. Milk samples were collected and cultured in parallel on both blood and nutrient agars. Of the total samples, 30/53 was well grown on both media and sub_ cultured on nutrient agar for further identification using primary and secondary biochemical tests. Accordingly, 30 milk samples showed typical large, round, golden yellow colonies of Staphylococcus aureus that frequently surrounded by zones of clear beta-hemolysis when grown on blood agar, round shaped grape like clusters we observed under a microscope after staining with gram stain, catalase­_ positive Staphylococcus aureus with bubble formation was observed and typical yellow pigmentation was observed on mannitol salt agar which is a selective medium for the genus Staphylococcus. Finally, 30(56.6 %) case of Staphylococcus aureus were identified with the coagulase test and a clumping result observed. Hence, implementing hygienic conditions, creating awareness of control and prevention of subclinical mastitis in dairy farms and conducting drug sensitivity tests for Staphylococcus aureus are recommended.

Schistosomiasis is a Neglected Tropical Disease that is endemic in sub-Saharan Africa, with over 90% of global cases occurring in the region. Poverty, inadequate healthcare infrastructure, and limited access to water and sanitation contribute to the high prevalence of the disease. Despite efforts to control and interrupt the diseases, a reduction in the transmission rates have not been realized owing to a number of challenges. This article highlights the challenges of schistosomiasis control in Africa and recommends strategies for successful interventions. These strategies include prioritizing government backing, investing in academic partnerships, strengthening integrated health programs, targeting communities through the Primary Healthcare system, and adopting home-grown solutions. Additionally, it is essential to address the knowledge gap hindering effective control of the disease and the risk of re-infection after treatment. By implementing these strategies, it is possible to achieve the World Health Organization’s 2021-2030 goal of eliminating schistosomiasis and reducing its prevalence of heavy infection to less than 1%.

The World Health Organization's definition of oral health frames the discussion, highlighting its holistic nature encompassing physiological, psychosocial, and functional dimensions. The current estimates of oral diseases in Tanzania and around the world underscore the urgency of intervention, particularly in light of rising sugar consumption trends. The unique challenges facing Tanzania, including inadequate knowledge, limited infrastructure, and disparities in oral healthcare access, are analyzed within the broader context of sub-Saharan Africa's health priorities. This perspective addresses the multifaceted challenges of oral health neglect in Tanzania, emphasizing the imperative for a comprehensive and integrated approach. The commentary offers a detailed exploration of determinants contributing to oral health neglect, spanning socioeconomic, behavioral, and commercial factors, with a focus on their implications for Tanzanian communities. Recommendations are presented as a strategic roadmap, encompassing public health education, integrated healthcare services, government intervention, educational programs, community engagement, financial accessibility, and research initiatives. By synthesizing these recommendations into a cohesive framework, a proactive and collaborative approach to mitigate the consequences of oral health neglect in Tanzania, emphasizing the need for transformative policies 3and cultural sensitivity are therefore envisioned.

Rabies, a deadly zoonotic disease caused by lyssaviruses, poses an escalating and severe threat in Nepal’s far western region. The recent unprecedented outbreak of rabies has surged across the Kailali and Kanchanpur districts of Sudurpaschim province, marked by a staggering 92.30% rabies positivity rate in suspected samples. Within a year, there were 84 confirmed outbreaks, with Kailali reporting 32 and Kanchanpur reporting 50, which underscores the severity of the situation in these districts. The disease has affected diverse animal species, including pigs, which marks the first case in Nepal. Considering the historically low rabies cases in the province, the current situation is alarming and necessitates prompt government intervention. Challenges include the absence of a comprehensive national rabies control policy, limited resources, and inadequate awareness in rural areas. To address this crisis, urgent action is necessary, requiring a multidisciplinary approach, collaboration between government and non-government agencies, prioritization of rural areas, improved health infrastructure, and strengthened surveillance.

Period poverty is the inability of menstruators to have access to all they need for proper handling of their menstruation which includes; access to menstrual products, proper menstrual education and sanitary facilities. It is a big threat, especially in low and middle-income countries if not properly addressed and a hindrance to the achievement of sustainable development goals. Period poverty has resulted in girls missing classes due to lack of access to menstrual products. Also some women and girls tend to use pieces of clothing, tissues and other unhygienic material for the management of their menstruation due to their inability to afford disposable pads. The hike in price of disposable pads has made them a luxury for many girls to have especially in low and middle-income countries. The amount of waste generated by the use of these products is alarming and detrimental to the ecosystem. There is a need to have a menstrual product that is affordable and eco-friendly; reusable pads fit into this description. The issue of whether menstruators would welcome the use of reusable pads due to fear of being laughed at or believe that reusable pads can lead to infections manifests as a result of a lack of proper education concerning these products. Studies prove that reusable pads are not associated with any form of infection and could be a better alternative to disposable pads. This paper aims to emphasize on the important role the use of reusable pads can play towards ending period poverty with prioritizing adequate menstrual health education and improved water, sanitation and hygiene facilities.

Introduction: Scrub typhus is a neglected life threatening acute febrile illness caused by bacteria Orientia tsutsugamushi and it is a vector-borne zoonotic disease. In 2009, scrub typhus outbreak at Gedu has awakened Bhutan on the awareness and testing of the disease.Information and data of the study highlights the need for in depth surveillance, awareness among prescribers and initiate preventive measures in the country. Methods: We used retrospective descriptive study through review of laboratory registers across three health centres in Zhemgang district, south central Bhutan. The laboratories registers have been transcribed into CSV file using Microsoft excel. Variables of interest were collected from the registers and then analysed using open statistical software R, (R Core Team (2020). R: A language and environment for statistical computing. R Foundation for Statistical Computing, Vienna, Austria.) And use of mStats package, (MyoMinnOo (2020). mStats: Epidemiological DataAnalysis. R package version 3.4.0.) Results: Of the total 922 tests prescribed for suspected scrub typhus in the three health centers in Zhemgang, only 8.2 % (n=76) were tested positive. Of these, Panbang Hospital had highest reported positive for scrub typhus with 56.6 %( n=43) followed by Yebilaptsa Hospital 35.5 %( n=27) and Zhemgang Hospital with 7.9 %( n=6). The female gender is comparably more affected as opposed to male with 57.9% (n=44) of the positive cases being female. The prevalence of scrub typhus seems to be affected by the seasonal variation as the months of Spring, Summer and Autumn together accounts for 98.7%(n=75) of total positive cases. The year 2019 noted significant scrub typhus cases accounting to 89.5 %(n=68) of the total positive cases over the two years. Conclusions:The overall tests tested positive of the scrub typhus infection within two years was 8.2%.

Introduction:A medical condition characterized by the congenital absence of skin, predominantly affecting the lower extremities, blisters on both skin and mucous membranes, and congenital absence and deformities in nails, has been identified within a familial context(1). The inheritance pattern aligns with a fully penetrant, autosomal dominant gene(1).In 1966, Bart introduced Bart syndrome, a condition marked by the simultaneous occurrence of congenital epidermolysis bullosa, localized congenital absence of skin affecting the extremities, and the abnormal shedding or dystrophy of nails(2). This syndrome is fascinating in the medical field due to its more optimistic prognosis when contrasted with other epidermolysis bullosa types(2). This type is known as Aplasia cutis congenital type VI(3).In this study, we have presented a case of a neonate with some disorders that guide us to different diagnoses and syndromes, such as CHIME syndrome and Barth syndrome, that have contributed.

IPCC claims that Global Warming is caused more or less exclusively by anthropogenic emissions of CO2. Therefore, only a total stop of these emissions could avoid a disaster. In IPCC’s reasoning, two concepts are central: The “constant airborne fraction”, according to which about 50 % of all anthropogenic emissions remain in the atmosphere, whatever the emissions and whatever the concentration, and the “fixed carbon budget”, which is the maximum amount humans may emit, when Global Warming should stay below a given limit, independent of the temporal distribution of the emissions. In this article, it is shown that three prerequisites must be fulfilled for these two central concepts to be viable: All natural sources of CO2 must have remained constant, the short-term partners of the atmosphere must store the same amount of CO2 as the atmosphere itself, and the atmosphere together with its short-term partners must be a closed system. And it is shown with high confidence that, according to the rules of physics, all three are not fulfilled. If this were confirmed, it would have a serious impact on the entire climate debate. A careful review seems to be needed urgently.

In this paper, a numerical dart leader model has been implemented to understand the leader’s development and the corresponding electric field changes observed by the 3D Broadband Mapping And Polarization (BIMAP-3D) system. The model assumes the extending leader channel is equipotential and has a linear charge distribution induced by an ambient electric field. The charge distribution induced by the ambient field can be used to model the electric field change at the ground. We then find the ambient electric field which best fits the field change measurements at the two BIMAP stations. The estimated ambient electric field decreases in the direction of dart leader propagation. Our observations and modeling results are consistent with our earlier hypothesis that dart leader speed is proportional to the electric field at the leader tip. The model also supports our earlier analysis that leader speed variations near branch junctions were due to previous charge deposits near the junctions. The modeled tip electric field is generally lower than the breakdown field unless the pre-dart-leader channel has a significant temperature of ~3000 K. This is consistent with the fact that dart leaders typically do not form new branches into the virgin air. Furthermore, the tip field is generally close to the negative streamer stability field at ambient temperatures, explaining the nature of the narrow and well-defined channel structure. In addition to the charge distribution and the ambient and tip electric field, the development of the channel potential and current distribution are also presented. 

Fluoride (F) has been employed worldwide to control dental caries. More recently, it has been suggested that the consumption of low doses of F in the drinking water may reduce blood glucose levels, introducing a new perspective for the use of F for the management of blood glucose. However, the exact mechanism by which F affects blood glucose levels remains largely unexplored. Given that the small gut plays a pivotal role in glucose homeostasis, the aim of this present study was to investigate the proteomic changes induced by low doses of F in the ileum of female non-obese-diabetic (NOD) mice. Forty-two female NOD mice were divided into two groups based on the F concentration in their for 14 weeks: 0 (control) or 10 mg/L. At the end of the experimental period, the ileum was collected for proteomic and Western Blotting analyses. Proteomic analysis indicated an increase in isoforms of actin, gastrotropin (confirmed by Western Blotting), several H2B histones and enzymes involved in antioxidant processes, as well as a decrease in enzymes essential for energy metabolism. In summary, our data indicates an adaptive response of the organism to preserve protein synthesis in the ileum, despite significant alterations in energy metabolism typically induced by F, therefore highlighting the safety of controlled fluoridation in water supplies.

Processing negative stimuli holds profound significance for survival, yet excessive focus on this information can lead to poor social adaptation. Trust violations, common occurrences in negative interpersonal interactions, result in individuals allocating greater cognitive resources towards processing negative stimuli. However, it is still unclear how trust violations influence the ability to control interference from negative stimuli. Therefore, this study employed the Emotional Stroop paradigm (Experiment 1) and the cued Ultimatum game (Experiment 2), using ERP technology to explore how trust violations influence emotional interference control abilities. In Experiment 1, the results showed that the violation group exhibited smaller SP amplitudes in the negative interference condition compared to the no-interference condition during the emotional Stroop paradigm. In Experiment 2, the violation group exhibited smaller SP amplitudes when benign cues were contaminated by threatening information relative to when they were not. Moreover, the violation group displayed higher P3 amplitudes for untrustworthy cues and angry faces than for trustworthy cues and happy faces, respectively. These findings were not observed in the control group. Collectively, these results suggest that trust violations not only draw more cognitive resources towards processing negative stimuli but also undermine interference control ability towards these stimuli.
