LITHOLOGICAL AND PALEOCOMMUNITY VARIATION ON A MISSISSIPPIAN (TOURNAISIAN) CARBONATE RAMP, MONTANA, USA
Authors: BROWN GARETT M. 
Published: March 2021

ABSTRACTThe ecological structure of ancient marine communities is impacted by the environmental gradients controlling assemblage compositions and the heterogeneous distribution of sediment types. Closely spaced, replicate sampling of fauna has been suggested to mitigate the effects of such heterogeneity and improve gradient analyses, but this technique has rarely been combined with similar sampling of lithologic data. This study analyses lithological and faunal data to determine the environmental gradients controlling the composition of Mississippian fossil assemblages of the lower Madison Group in Montana. Eighty-one lithological and faunal samples were collected from four stratigraphic columns in Montana, which represent the deep-subtidal, foreshoal, and ooid-shoal depositional environments within one third-order depositional sequence. Cluster analysis identifies three distinct lithological associations across all depositional environments—crinoid-dominated carbonates, peloidal-crinoidal carbonates, and micritic-crinoidal carbonates. Cluster analysis and nonmetric multidimensional scaling (NMS) identifies a highly diverse brachiopod biofacies and a solitary coral-dominated biofacies along an onshore-offshore gradient. Carbonate point count data and orientation of solitary corals indicate that substrate and wave energy are two potential variables that covary with the onshore-offshore gradient. Overlaying lithological information on the NMS indicates a secondary gradient reflecting oxygen that is expressed by increasing bioturbation and gradation from brown to dark gray carbonates to medium-light gray carbonates. Taken together, these findings demonstrates how combining closely spaced, replicate sampling of lithologic and faunal data enhances multivariate analyses by uncovering underlying environmental gradients that control the variation in fossil assemblages.

Published: March 2021

Nowadays, it is convenient for us to use a search engine to get our needed information. But sometimes it will misunderstand the information because of the different media reports. The Recommender System (RS) is popular to use for every business since it can provide information for users that will attract more revenues for companies. But also, sometimes the system will recommend unneeded information for users. Because of this, this paper provided an architecture of a recommender system that could base on user-oriented preference. This system is called UOP-RS. To make the UOP-RS significantly, this paper focused on movie theatre information and collect the movie database from the IMDb website that provides information related to movies, television programs, home videos, video games, and streaming content that also collects many ratings and reviews from users. This paper also analyzed individual user data to extract the user’s features. Based on user characteristics, movie ratings/scores, and movie results, a UOP-RS model was built. In our experiment, 5000 IMDb movie datasets were used and 5 recommended movies for users. The results show that the system could return results on 3.86 s and has a 14% error on recommended goods when training data as . At the end of this paper concluded that the system could quickly recommend users of the goods which they needed. The proposed system will extend to connect with the Chatbot system that users can make queries faster and easier from their phones in the future.
How to plan urban green space in cold regions of China to achieve the best cooling efficiency

Abstract
With the acceleration of urbanization, the urban heat island (UHI) effect has intensified. Urban green space can retard the UHI effectively. However, most existing work has only focused on hot regions, while little attention has been paid to cold regions. Furthermore, existing research does not classify urban green spaces according to the presence or absence of water, which will lead to inaccurate results. This paper takes four cities in cold regions of China as examples and studies the cooling effects of two different types of urban green space. The results indicate that for green spaces without water, the cooling intensity is related to the background temperature and area of the green spaces, while for green spaces containing water bodies, the area of the internal water body is the key influencing factor. Specifically, there is a threshold value of efficiency (TVoE) for the area of green spaces without water, while there is no TVoE for green spaces containing water bodies. Additionally, there is a TVoE for the water/land ratio of the green spaces containing water bodies in the four cities. The methods and results of this study can provide reference for future research and for urban planners designing urban green spaces.

Abstract
Background: Psychomotor stimulants are the most commonly used prohibited substances after cannabis. Globally, their use reaching epidemiological proportions and is one of the most common causes of death in many countries. In recent years, more research, define drug use as the leading cause of serious cardiovascular pathologies ranging from abnormal heart rhythms to heart attack and sudden cardiac death. The reactive oxygen species generation, toxic metabolites formation and oxidative stress play a significant role in cocaine-induced cardiotoxicity. Main body: In the present review, we discuss various studies related to dopamine neurotransmission and oxidative stress, with a focus on the cardiotoxicity of the cocaine molecule and the cardiovascular complications that occur after cocaine use. Conclusion: Hypothetically, this study can serve as a basis for developing a rapid and effective method for determining oxidative stress levels by monitoring changes in the redox status of patients with cocaine intoxication.

Abstract
Background: In potentially severe diseases in general and COVID-19 in particular, it is vital to early identify those patients who are going to develop complications. The last update of a recent living systematic review dedicated to predictive models in COVID-19,[1] critically appraises 145 models, 8 of them focused on prediction of severe disease and 23 on mortality. Unfortunately, in all 145 models, they found a risk of bias significant enough to finally "not recommend any for clinical use". Authors suggest concentrating on avoiding biases in sampling and prioritising the study of already identified predictive factors, rather than the identification of new ones that are often dependent on the database. Our objective is to develop a model to predict which patients with COVID-19 pneumonia are at high risk of developing severe illness or dying, using basic and validated clinical tools.Methods: prospective cohort of consecutive patients admitted in a teaching hospital during the “first wave” of the COVID-19 pandemic. Follow-up to discharge from hospital. Multiple logistic regression selecting variables according to clinical and statistical criteria. Results: 404 consecutive patients were evaluated, 392 (97%) completed follow-up. Mean age was 61 years; 59% were men. The median burden of comorbidity was 2 points in the Age-adjusted Charlson Comorbidity Index, CRB was abnormal in 18% of patients and basal oxygen saturation on admission lower than 90% in 18%. A model composed of Age-adjusted Charlson Comorbidity Index, CRB score and basal oxygen saturation can predict unfavorable evolution or death with an area under the ROC curve of 0.85 (95% CI: 0.80-0.89), and 0.90 (95% CI: 0.86 to 0.94), respectively.Conclusion: prognosis of COVID-19 pneumonia can be predicted in the out-of-hospital environment using two classic prognostic scales and a pocket pulse oximeter.
Insilico identification of a ferroportin inhibitor for the management of iron-overload condition in Beta Thalassemia major patients.

Published: March 2021

Abstract
The reason of high mortality rate in the patients of beta-thalassemia major is iron overload because it leads to many secondary complications. Condition of iron overload is known as hemochromatosis (HC). HC causes distorted formation of HFE protein that disturbs the whole pathway of HAMP protein synthesis which results in unbounded form of ferroportin and hence iron keeps absorbing in the body, leading to iron accumulation. The current study was conducted to identify a potential phytochemical that could bind to ferroportin and inhibits its iron absorbing activity within the body. The 3D structure of Ferroportin was unavailable in protein data bank PDB, therefore, it was developed by using different bioinformatics tools and best structure was identified through SAVES and RAMPAGE analysis. This best structure was docked with a library of 1010 bioactive phytochemicals by using MOE-2009 software. The top-ten ranked potential inhibitors were then evaluated for drug-like properties through molsoft and Molinspiration server followed by ADMET analysis. Our study demonstrated that “Taxifolin’ showed the maximum binding affinity with Ferroportin and also demonstrates maximum drug-like properties. Thus this compound could be used as a potential inhibitor of ferroportin. However, in-vitro and in-vivo studies must be conducted to validate the therapeutic potential of taxifolin against hemochromatosis.

Abstract
Fusarium head blight (FHB) remains a devastating disease in bread wheat (Triticum aestivum L.) and other small grains. Genetic resistance to FHB is a complex trait; in addition to active physiological resistance, plant developmental and morphological traits may indirectly affect disease progression and provide a passive mechanism of resistance. In this study, we investigated the relationship between FHB type II resistance and spike architecture traits in a recombinant inbred line (RIL) population of bread wheat. Disease resistance traits were FHB severity at 21 days post inoculation (dpi) and area under the disease progress curve (AUDPC). Spike architecture traits measured were rachis length, spike density, number of spikelets per spike, florets per spike and florets per spikelet. The RIL population showed significant variation for all traits. Heritability values were moderate to high for FHB severity (0.69) and AUDPC (0.63) and high for the spike architecture traits (0.74 - 0.92). FHB severity and AUDPC showed a moderate and significant association with the number of florets per spike (r = 0.38 and r = 0.31, respectively) and with the number of florets per spikelet (r = 0.28 and r = 0.27, respectively), reflecting a greater spread of the fungus in spikes with higher floret number. These results suggest that the number of florets per spike and the number of florets per spikelet should be considered in FHB resistance breeding efforts, because selection of lines with higher number of florets could lead to a correlated selection response towards increased FHB levels under field conditions.

Abstract
Brazil is one of the countries with the greatest genetic diversity in lima beans ( Phaseolus lunatus L.), which has been maintained both on farm and in germplasm banks. The knowledge of this diversity in the country is extremely important for developing a strategy for use and conservation. The objective of this study was characterizing landraces lima bean accessions from different regions in Brazil . Twenty two accessions conserved in the Phaseolus Germplasm Bank from UFPI (Piauí-Brazil) were characterized with 37 agro-morphological descriptors and 15 microsatellite markers. In the agro-morphological characterization, the maximum value of genetic divergence was obtained for the pair UFPI-262 and UFPI-252 (D = 88.74). The UPGMA grouping made it possible to form four groups. Tocher's optimization method enabled the formation of 10 groups. Regarding molecular characterization, 10 loci presented polymorphism, and the number of alleles per locus varied from two to seven. The Polymorphic Information Content (PIC) varied from 0.0767 to 0.7240. The loci GATS91 and PVat001 were highly informative and can be indicate for further studies involving the lima bean. The genetic diversity found (He = 0.316) was higher than that reported in the Yucatán Peninsula, a region indicated as a center of diversity for lima bean. Thus, the agro-morphological and molecular characterization were efficient in quantifying the genetic divergence between the studied accessions. The data found in this research provide a valuable resource for geneticists to subsidize breeding programs involving the lima bean.

Abstract
Plastic waste is a relevant challenge for waste management sector and further technological means has to be urgently researched. Near infrared spectroscopy (NIR), as a non-destructive, cost-effective and mature technology, is currently operational in some waste-sorting facilities. However, NIR remains challenging to discriminate different black plastics because black targets have low reflectance in the its spectral region. Therefore, this study aimed to address the problem in black plastic classification. Seven kinds of plastics: High Impact Polystyrene (HIPS), Acrylonitrile Butadiene Styrene (ABS), High Density Polyethylene (HDPE), Polyethylene terephthalate (PET), Polyamide 66 (PA66), Polycarbonate (PC) and Polypropylene (PP), were prepared for analysis, in which black plastic accounted for half of the total samples (84/159). Some methods such as partial least squares discrimination analysis (PLS-DA), soft independent modelling of class analogy (SIMCA), linear discriminant analysis (LDA) and convolutional neural network (CNN) were used to classify the plastics. Coupling with proper preprocessing methods, PLS-DA and LDA could provide an accuracy of 57.00%, and SIMCA of 69.98%. Meanwhile, the NIR spectra fed into the CNN model as one-dimensional data, the accuracy of CNN model could reach 98.00%. Compared to the SIMCA, PLS-DA and LDA, the accuracy of CNN provided an average improvement of 28-41%. Results demonstrated that NIR spectra combined with CNN gave an excellent accuracy which was potential to solve the bottleneck problem of black plastic discrimination.

Abstract
Background. Nurses are trained to establish a trusting relationship with patients in order to create a salutogenic environment. However, in tech-heavy care settings, such as haemodialysis units, dehumanising practices tend to emerge and take root for various reasons to the potential detriment of both patients and nurses. For patients, this may lead to a deterioration of quality of life and, ultimately, of health status. For nurses, it may cause a deterioration of the work environment and, in turn, of quality of working life. Swiss researchers developed, based on Watson’s Theory of Human Caring, and tested, by way of an experimental design, a brief educational intervention for haemodialysis nurses to strengthen their humanistic practice in the aim of improving the nurse-patient relationship and nurse quality of working life.Methods. One hundred and one haemodialysis nurses recruited in ten hospitals in French-speaking Switzerland were randomised into an experimental group that received the intervention and a control group that did not. The nurse-patient relationship was measured with the Caring Nurse-Patient Interaction Scale (EIIP-70) and nurse quality of life at work was measured with the Quality of Work Life Questionnaire at four time points: pre-intervention, intervention completion, and six-month and one-year follow-ups. Random intercept regression analysis was used to evaluate change over time in the two variables under study.Results. The intervention appeared to reinforce nurse attitudes and behaviours geared to a more humanistic practice. The effect seemed to fade over time but was still present one year post-intervention, though limited to certain dimensions of the nurse-patient relationship. Nurse quality of working life, too, seemed positively impacted. The cultural dimension of nurse quality of working life, that is, the degree to which everyday work activities attune with personal and cultural values, recorded the most noticeable improvement.Conclusions. Results support a positive effect of the intervention over both the short term and the medium-to-long term. A brief intervention of the sort may constitute an effective means to improve the nurse-patient relationship by preventing or reducing dehumanising practices.Trial registration: NCT03283891
