Global production patterns: Understanding the relationship between greenhouse gas emissions, agriculture greening and climate variability

Climate change due to increased greenhouse gas emissions (GHG) in the atmosphere has been consistently observed since the mid-20th century. The profound influence of global climate change on greenhouse gas (GHG) emissions, encompassing carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O), has established a vital feedback loop that contributes to further climate change. This intricate relationship necessitates a comprehensive understanding of the underlying feedback mechanisms. By examining the interactions between global climate change, soil, and GHG emissions, we can elucidate the complexities of CO2, CH4, and N2O dynamics and their implications. In this study, we evaluate the global climate change relationship with GHG globally in 246 countries. We find a robust positive association between climate and GHG emissions. By 2100, GHG emissions will increase in all G7 countries and China while decreasing in the United Kingdom based on current economic growth policies, resulting in a net global increase, suggesting that climate-driven increase in GHG and climate variations impact crop production loss due to soil impacts and not provide climate adaptation. The study highlights the diverse strategies employed by G7 countries in reducing GHG emissions, with France leveraging nuclear power, Germany focusing on renewables, and Italy targeting its industrial and transportation sectors. The UK and Japan are making significant progress in emission reduction through renewable energy, while the US and Canada face challenges due to their industrial activities and reliance on fossil fuels.

Evaluating the impact of roads on the diversity pattern and density of trees to improve the conservation of species

Roadside trees alter biotic and abiotic factors of plants diversity in an ecosystem. Rows of plants grow along the roadside due to the interplay between the arrival of propagule and seedling establishment, which depends on the road's specifications, land pattern, and road administration and protection practices. A field study was conducted to measure the roadside tree diversity in the city of Karachi (Pakistan). A total of 180 plots, divided into three primary road groups, were surveyed. The highest quantity of tree biomass per unit area was found on wide roads, followed by medium roads. On narrow roads, the least biomass was detected. A single species or a limited number of species dominated the tree community. Conocarpus erectus was the most dominant non-native species on all types of sidewalks or roadsides, followed by Guaiacum officinale. A total of 76 species (32 non-natives and 44 natives) that were selectively spread along the roadsides of the city were studied. There was a significant difference in phylogenetic diversity (PD), phylogenetic mean pairwise distance (MPD), and phylogenetic mean nearest taxon distance (MNTD) among wide, medium, and narrow roads. Management practices have a significant positive correlation with diversity indices. Our study identified patterns of diversity in roadside trees in Karachi. It provides the basis for future planning for plant protection, such as the protection of plant species, the maintenance of plant habitats, and the coordination of plant management in Karachi.

A hybrid approach to forecast the COVID-19 epidemic trend

Studying the progress and trend of the novel coronavirus pneumonia (COVID-19) transmission mode will help effectively curb its spread. Some commonly used infectious disease prediction models are introduced. The hybrid model is proposed, which overcomes the disadvantages of the logistic model's inability to predict the number of confirmed diagnoses and the drawbacks of too many tuning parameters of the SEIR (Susceptible, Exposed, Infectious, Recovered) model. The realization and superiority of the prediction of the proposed model are proven through experiments. At the same time, the influence of different initial values of the parameters that need to be debugged on the hybrid model is further studied, and the mean error is used to quantify the prediction effect. By forecasting epidemic size and peak time and simulating the effects of public health interventions, this paper aims to clarify the transmission dynamics of COVID-19 and recommend operation suggestions to slow down the epidemic. It is suggested that the quick detection of cases, sufficient implementation of quarantine and public self-protection behaviours are critical to slow down the epidemic.

Feature-based multi-criteria recommendation system using a weighted approach with ranking correlation

With the increase of online businesses, recommendation algorithms are being researched a lot to facilitate the process of using the existing information. Such multi-criteria recommendation (MCRS) helps a lot the end-users to attain the required results of interest having different selective criteria – such as combinations of implicit and explicit interest indicators in the form of ranking or rankings on different matched dimensions. Current approaches typically use label correlation, by assuming that the label correlations are shared by all objects. In real-world tasks, however, different sources of information have different features. Recommendation systems are more effective if being used for making a recommendation using multiple criteria of decisions by using the correlation between the features and items content (content-based approach) or finding a similar user rating to get targeted results (Collaborative filtering). To combine these two filterings in the multicriteria model, we proposed a features-based fb-knn multi-criteria hybrid recommendation algorithm approach for getting the recommendation of the items by using multicriteria features of items and integrating those with the correlated items found in similar datasets. Ranks were assigned to each decision and then weights were computed for each decision by using the standard deviation of items to get the nearest result. For evaluation, we tested the proposed algorithm on different datasets having multiple features of information. The results demonstrate that proposed fb-knn is efficient in different types of datasets.

Predictive Data Modeling Using sp-kNN for Risk Factor Evaluation in Urban Demographical Healthcare Data

Healthcare diseases are spreading all around the globe day to day. Hospital datasets are full from the data with much information. It's an urgent requirement to use that data perfectly and efficiently. We propose a novel algorithm for predictive model for eye diseases using KNN with machine learning algorithms and artificial intelligence (AI). The aims are to evaluate the connection between the accumulated preoperative risk variables and different eye diseases and to manufacture a model that can anticipate the results on an individual level, thus giving relevance to impactful factors and geographic and demographic features. Risk factors of the desired diseases were calculated and machine learning algorithm applied to provide the prediction of the diseases. Health monitoring is an economic discipline that focuses on the effective allocation of medical resources, mainly to maximize the benefits of society to health through the available resources. With the increasing demand for medical services and the limited allocation of medical resources, the application of health economics in clinical practice has been paid more and more attention, and it has gradually played an important role in clinical decision-making.

External trial deep brain stimulation device for the application of desynchronizing stimulation techniques

In the past decade deep brain stimulation (DBS)-the application of electrical stimulation to specific target structures via implanted depth electrodes-has become the standard treatment for medically refractory Parkinson's disease and essential tremor. These diseases are characterized by pathological synchronized neuronal activity in particular brain areas. We present an external trial DBS device capable of administering effectively desynchronizing stimulation techniques developed with methods from nonlinear dynamics and statistical physics according to a model-based approach. These techniques exploit either stochastic phase resetting principles or complex delayed-feedback mechanisms. We explain how these methods are implemented into a safe and user-friendly device.

Inefficient delivery of yeast cells as an explanation for reduced plating efficiency of Candida albicans

The plating efficiency for fungal yeast cells is usually less than that expected from microscopic counts, and a number of explanations for this phenomenon have been proposed. The present study was undertaken to explore possible reasons for reduced plating efficiency of Candida albicans. Explanations that we evaluated and found unlikely included: ineffectiveness of different culture media and/or incubation temperatures for growing colonies, insufficient area of the plate available for expression of individual colonies, production of microcolonies, and inaccurate counting of the organisms in the inoculum. An assay for delivery of the inoculum into tissue culture plate wells indicated that reduced delivery of the organisms accounted for lower than expected plating efficiency. C. albicans yeast cells grown under low glucose conditions and expected to have reduced adhesiveness were found to have higher values for both delivery and plating efficiency in our assays. In summary, our results indicate that reduced plating efficiency for C. albicans under the conditions used for these experiments is best explained by the loss of some yeast cells during preparation of the inocula or delivery of the yeast cells onto the plates.

Emergency redo mitral valve replacement in a 27-year-old pregnant female with a clotted prosthetic mitral valve, preoperative fetal demise and postoperative ventricular assist device: a case report

A 27-year-old Laotian woman with a St Jude mechanical mitral valve became pregnant, requiring a change in her anticoagulant after the first trimester when her warfarin sodium (coumadin) was replaced with enoxaparin sodium (lovenox). Her prosthetic valve clotted and became dysfunctional. She was 16 weeks pregnant and was taken to the operating room for emergency surgery for replacement of the valve. The fetus had not been viable for 1-2 weeks, but still remained in utero. The clotted valve was replaced with another St Jude valve of a slightly smaller diameter (27 mm). The patient could not be weaned from bypass so a right ventricular assist device (RVAD) was inserted. The patient was weaned from the RVAD after 2 days of support. Two days following removal of the RVAD the fetus spontaneously aborted. The patient had a long, complicated hospital course and was discharged 3 months later. She subsequently died 4 months after discharge of a cerebral hemorrhage from excessive anticoagulation.

Veillonella parvula meningitis: case report and review of Veillonella infections

Veillonella parvula is a small, nonfermentative anaerobic gram-negative coccus that is part of the normal flora of the mouth, gastrointestinal tract, and vagina in humans. When isolated from clinical specimens, V. parvula is often regarded as a contaminant or commensal, but it has been implicated as a pathogen in infections of the sinuses, lungs, heart, bone, and central nervous system. Meningitis, however, is extremely rare; to our knowledge, only 2 cases have been previously described in the literature. We report a case of V. parvula meningitis and review the literature on Veillonella infections.

Pleuropulmonary and skeletal lymphangiomatosis with chylothorax and chylopericardium

Congenital lymphangiomatosis of lung and bone, with or without chylothorax, is a rare but often fatal systemic lymphatic malformation. In those who survive infancy and early childhood, parietal pleurectomy with excision of lymphatic lakes and ligation of the thoracic duct can be successful. Two patients with lymphangiomatosis are described, 1 with chylothorax and chylopericardium with generalized skeletal lesions and the other with pleuropulmonary lesions and chylothorax. Both were successfully treated with parietal pleurectomy, excision of lymphatic lakes, and ligation of lymphatics, including the thoracic duct. To our knowledge, the triad of generalized skeletal lymphangiomatosis, chylopericardium, and chylothorax has not been previously reported.

Giant lymph node hyperplasia of the mediastinum (Castleman's disease)

Giant lymph node hyperplasia is a rare, benign disease involving lymph nodes in various locations, predominantly in the mediastinum. There are two variants: plasma cell (earlier and/or acute) and hyaline-vascular, more chronic with an intermediate transitional type. The usual presentation is a solitary well-circumscribed asymptomatic mass lesion, often attaining large size, with infrequent associated hematologic manifestations. A case of giant lymph node hyperplasia involving the paravertebral superior mediastinum is reported. Surgical excision was the treatment of choice in a 65-year-old man, and at thoractomy, an encapsulated mass was excised from the posterior superior mediastinum. The patient had an uneventful postoperative course and was discharged on the tenth postoperative day. Three years later, he is well and employed as a carpenter.

Selection for feed efficiency in mice under AD libitum and restricted feeding terminated by fixed time or quantity of intake

Mass selection for feed conversion efficiency (FCE) in mice was practiced for six generations in two lines fed ad libitum (AL) and two lines restricted to 80% of ad libitum (R). In one line of each pair of selected lines and test period was terminated after a fixed time (14 days) (TAL and TR) and in the second line of the pair after consumption of a fixed time (14 days) (TAL and TR) and in the second line of the pair after consumption of a fixed quantity of feed (WAL and WR). A random mating control line (C), also fed ad libitum was maintained throughout the study. Correlated traits measured were initial weight, final weight, weight gain, feed consumption and litter size. A significant response in FCE was found in the TR and WR lines, the regression of response on generation number being -1.36 +/- 0.31 and -1.09 +/- 0.39 respectively. There was a significant decrease in initial weight on test in the TR and WAL lines and in those lines mature body weight was significantly lower than in the C line when measured in the sixth generation. Heritability of FCE was higher in the restricted line (0.31 +/- 0.12 for TR and 0.37 +/- 0.29 for WR) than in the ad libitum lines (0.13 +/- 0.20 for TAL and 0.13 +/- 0.25 for WAL). Heritability of FCE was 0.17 +/- 0.31 in the C line. Phenotypic and genetic correlations between FCE and weight gain were high and negative in all lines. Progeny from each line were tested in each of the other feeding regimes each generation to measure lin X feeding regime interaction. This interaction was statistically significant.

Management of isolated blunt duodenal injury

Five cases of duodenal injuries were treated in our hospital between January 1, 1975 and June 18, 1979. They belonged to the Class II and early Class III of duodenal injuries. They were treated with simple closure of the perforation in a single or double layer with external drainage. Only in one case were gastrojejunostomy and bilateral vagotomy added because the patient had a history of ulcer disease. The delay in operative treatment ranged between five and 48 hours. All responded well to the surgical treatment. In the instance of the longest operative delay, a purulent drainage occurred and it responded promptly to a selective antibiotic therapy. The average hospitalization stay was nine days for the patients operated upon early, whereas it was 15 days for the two delayed cases. No mortality was recorded.
