3D Global Heat Transfer Model on Floating Zone for Silicon Single Crystal Growth

In this paper, a three‐dimensional global heat transfer model to describe the floating zone of silicon single‐crystal growth is proposed. The steady‐state calculations considering argon gas flow, feed rod, silicon melt and crystal are carried out using open source software OpenFOAM with no assumptions of symmetry. From the global calculation, a three dimensional solid‐liquid interface has been obtained. Furthermore, the cooling effect of gas flow in three dimensions is considered, and the three‐dimensional current‐density distribution of the inductor is calculated. By considering the asymmetrical electromagnetic field induced by the inductor, the calculations reveal a deflection of the asymmetrical solid‐liquid interface.
Understanding Capacity Saturation in Incremental Learning

In class-incremental learning, a model continuously learns from a sequential data stream in which new classes are introduced. There are two main challenges in class- incremental learning: catastrophic forgetting and capacity saturation. In this work, we focus on capacity saturation where a learner is unable to achieve good generalization due to its limited capacity. To understand how to increase model capacity, we present the continual architecture design problem where at any given step, a continual learner needs to adapt its architecture to achieve a good balance between performance, computational cost and memory limitations. To address this problem, we propose Continual Neural Architecture Search (CNAS) which takes advantage of the sequential nature of class- incremental learning to efficiently identify strong architectures. CNAS consists of a task network for image classification and a reinforcement learning agent as the meta-controller for architecture adaptation. We also accelerate learning by transferring weights from the previous learning step thus saving a large amount of computational resources. We evaluate CNAS on the CIFAR-100 dataset in several incremental learning scenarios with limited computational power (1 GPU). We empirically demonstrate that CNAS can mitigate capacity saturation and achieve performances comparable with full architecture search while being at least one order of magnitude more efficient.
Comparative Parameters of Occult and Multiple Brain Tumors In Human: The Implication for Therapy

Background Brain cancer treatment is a difficult task, because of complex nature of physico-chemical properties of brain, central nervous system (cns) acting drugs and drug carriers. Methods In view of this, literatures were searched with a view to assessing comparative mathematical parameters of occult and multiple primary brain tumors and their therapeutic outcomes. A total of thirteen patients comprised of eight males and five females who had suffered either occult or multiple brain tumors were used for the study. Tumor parameters and their therapeutic prognoses were mathematically determined. The data were analyzed using a modified Kaplan-Meier method at 5 % level of significance. Results Findings have shown that occult tumors such as meningiosarcoma (65.4cm3), teratoma (268 cm3), solitary brain tumor (20.6–22.4 cm3) and gliosarcoma (31.1 cm3) as well as multiple primary brain tumors; meningioma/diffuse astrocytoma (47.7 cm3), glioblastoma multiforme/pituitary adenoma (164. 59 cm3) and planum sphenoidale meningioma/pituitary adenoma (26.52 cm3) are deadly. However solitary brain tumor (4.2 cm3), glioblastoma multiforme/pituitary adenoma (12.77 cm3) and multimeningioma/pituitary adenoma (0.70 cm3) have high survival rate. Generally tumor weight (4.2–144.0 g), tumor density (0.24–0.96), total population of tumor cells (9.5 x 108-2.5 x 1011, rate of tumor cell migration (1.10–48.0 cm2/yr) and tumor radius (0.55-4.0 cm) are relatively moderate to very high, signifying that occult brain tumors may generate faster and may be more difficult to treat chemotherapeutically, radiotherapeutically, immunologically and surgically. Brain tumors affect male and female of 2–79 years old. Conclusions The locations of tumors are parietal, temporal, frontal, thalamic, frontoparietal, stellar, and planum sphenoidale lobes. Both occult and multiple brain tumors are diagnosed when all forms of therapy would have been useless.
British English-Speaking Speed 2020

It has been 30 decades since Tauroza & Allison measured the speed of British English in 1990 (Tauroza & Allisond, 1990). Has the speed of English speaking changed in this era of great development of thoughts and information explosion? Does the standard rate of oral English in EFL need to be adjusted accordingly? This paper analyses 200 speakers’ 79 corpus with a total duration of 77 hours and 58 minutes in four categories of news monologues, interviews, conversations, and academic lectures in the UK from 2020 to February, 2021, and calculates the speech rate of contemporary British English. It is found that the average speaking speed of British English has reached 198 words per minute (17% faster by 28 words) and 265 syllables per minute (10% faster by 25 syllables). Accordingly, the standard speech rate of EFL teaching should be improved.
Hydrothermal Liquefaction of Kraft Lignin in Subcritical Water: Influence of Phenol as Capping Agent

The depolymerization of LignoBoost Kraft lignin in subcritical water, i.e. hydrothermal liquefaction (HTL), was investigated using ZrO2, K2CO3, and KOH as catalysts in a fixed-bed reactor with recirculation. Focus was placed on the effect exerted by the concentration of the phenol in suppressing repolymerization, which is responsible for forming char. Feeds with various concentrations of phenol (2–10%) were investigated, and the results showed that phenol partially prevents repolymerization even at low concentrations. The bio-oil yield of (61.0 ± 2.7) % was fairly stable when the concentration of phenol was varied. In the case of the formation of char on the catalyst, the char yield revealed a weakly decreasing trend (14.6–12.3%) when the amount of phenol in the feed was increased. The results also showed that the phenolic monomers that are alkylated, such as o-/p-cresols, increased significantly with increasing concentrations of phenol, while aromatic compounds, based on a guaiacol ring structure, showed.

Abstract Introduction: The use of social media for marketing library services of academic libraries is growing day by day. The purpose of this study is to investigate the use of social media in marketing services of libraries of Iran, Tehran and Shahid-Beheshti universities of medical sciences. Method: The study used a survey method. The questionnaire was used for data collection. The study population included all librarians working in the libraries of Iran, Tehran and Shahid-Beheshti universities of medical sciences with at least a bachelor's degree in librarianship. Descriptive and analytical statistics were used to analyze the data by Spss24 software. Results: The status of using social media for marketing library services in libraries of Iran, Tehran and Shahid-Beheshti universities of medical sciences, based on 4P marketing mix, was as follows: in price components (cost-benefit) with an average of 2.4, location (social media) with an average of 2.36, product (library services) with an average of 2.29, and promotion components with an average of 2.27. Their level of use in all four components was relatively unfavorable. Conclusion: Due to the unfavorable level of using social media for marketing library services in these universities, it is necessary to encourage more effective planning to hold retraining and in-service courses in the areas of marketing, social media tools and content production in these media to encourage medical Librarians to know and use these tools in library services.
Long-term and actual golf performance and their relation to putting success and accuracy in amateur players

ABSTRACT This study aimed to evaluate the putting skills of amateur players and the relationship between these skills and long-term and actual performance. The participants (n = 34) performed tests from different distances (1 m, 3 m, 5 m) and slopes (uphill, downhill, right-left, left-right). Based on these tests, the accuracy and success of their putting were measured. ANOVA results showed that performance on 1 m putts was more accurate and successful than 3 m and 5 m putts. Furthermore, 3 m putts were more accurate and successful than 5 m putts on all slopes (p < 0.001). The participants with HCP ≤ 5 were more successful than the HCP 5.1–12 and HCP ≥ 12.1 groups, and HCP 5.1–12 players were more successful than HCP ≥ 12.1 players in 1 m and 3 m putts (p = .046). Accuracy did not vary between HCP groups. Initial putt slopes influence accuracy (p < 0.001) and success (p = .0038). Downhill and left–right slopes are associated with lower accuracy than other slopes and downhill slopes provide the best success at all distances. This study showed that putting skills play a crucial role in shaping the golf performance of amateur players.
Evaluation of heated air jet on pulp chamber temperature at different steps of the restorative protocol

Objectives: Evaluate of the heated air jet temperature (T) in the pulp chamber on cavity 5 depths and photoactivation stages for a bulk fill resin restorative protocol is evaluated. Methods: Class I cavity preparations were conducted at different depths (n = 8) through two protocols for adhesive volatilization (23 °C and 40 °C) and cavities were restored with the Filtek Bulk Fill resin. The pulp chamber temperature variation was evaluated at four steps (times) during the restorative protocol: I (initial), V (after volatilization), A (after photoactivation of the adhesive), and C (after photoactivation of the composite resin). To verify the assumptions of the normality of the errors and homoscedasticity, the Shapiro Wilk and Levene tests were conducted. Subsequently, two-way and three-way analysis of variance was carried out, followed by Tukey's post-hoc analysis (α = 0.05). Results: The maximum T at the different restorative steps, regardless of the volatilization protocol and cavity depth, was as follows: I (36.8 °C) = V (36.9 ºC) < A (37.2 °C) = R (37.8 ºC) (p <0.05). During V, a small greater variation was observed in pulp chamber temperature when dentin was volatilized at 40 °C (p <0.05) at very deep cavity depths (0.31 °C). The largest temperature variations (p <0.05) were observed during A (0.17–0.59 °C) and R (0.50–1.06 °C), reaching peak temperatures in the cavities.
Prioritizing Cancer lncRNA Modulators via Integrated lncRNA-mRNA Network and Somatic Mutation Data

Background: Long noncoding RNAs (LncRNAs) represent a large category of functional RNA molecules that play a significant role in human cancers. lncRNAs can be genes modulators to affect the biological process of multiple cancers.Methods: Here, we developed a computational framework that uses lncRNA-mRNA network and mutations in individual genes of 9 cancers from TCGA to prioritize cancer lncRNA modulators. Our method screened risky cancer lncRNA regulators based on integrated multiple lncRNA functional networks and 3 calculation methods in network. Results: Validation analyses revealed that our method was more effective than prioritization based on a single lncRNA network. This method showed high predictive performance and the highest ROC score was 0.836 in breast cancer. It’s worth noting that we found that 5 lncRNAs scores were abnormally high and these lncRNAs appeared in 9 cancers. By consulting the literatures, these 5 lncRNAs were experimentally supported lncRNAs. Analyses of prioritizing lncRNAs reveal that these lncRNAs are enriched in various cancer-related biological processes and pathways.Conclusions: Together, these results demonstrated the ability of this method identifying candidate lncRNA molecules and improved insights into the pathogenesis of cancer.

Understanding Rabies Persistence in Low-Density Fox Populations

ABSTRACT Arctic fox (Vulpes lagopus) and its tundra habitat are a unique system for the study of rabies virus epidemics. Contrary to theoretical calculations reporting a critical density (KT) of approximately 1 fox/km2 for rabies endemicity, arctic rabies persists at densities below this. The calculation of KT = 1 fox/km2 assumes uniform fox density across the landscape and unrestricted mixing between susceptible and infected foxes. We hypothesize that spatial heterogeneity arising from resource distribution or social structure may result in regions where rabies is endemic, even though average fox densities at the regional or landscape-level are below KT. To expand upon the limited body of research surrounding arctic rabies persistence, we examine arctic rabies via a two-patch structure. We find that arctic rabies can persist in heterogeneous landscapes where the mean carrying capacity is below the threshold carrying capacity required for endemicity in homogeneous landscapes. Rabies endemicity in low-carrying capacity regions within heterogeneous landscapes is further facilitated by high transmission rates, potentially due to non-breeding foxes (i.e. floaters), and when between-patch movement is restricted to latent and infected foxes. Our results suggest that rabies may persist in heterogeneous landscapes when the mean carrying capacity is as low as 0.25 foxes/km2.
THE ASSOCIATION OF SURGICAL SAFETY AND PATIENT SAFETY INCIDENT

Failure to perform surgical safety could have been caused several unwanted cases and result in disability and even death. This studied aims to analyze the association of surgical safety and patient safety incident. The studied design used was cross-sectional with a population of all surgery patients who was taken by purposive sampling technique. The researched variables was the implementation of surgical safety and patient safety incident. The researched instrument used a checklist with data analysis using the chi-square. the implementation of surgical safety shows mostly good results and there was no patient safety incident (87%), while the implementation of surgical safety shows sufficient results and there was no patient safety incident (7,4%) and patient safety incidents occur (1,9%). The implementation of surgical safety was poorly implemented and there was no patient safety incident (3,7%). The results of statistical analysis using chi-square obtained p-value (0,000) <α (0,05): the results showed a significant association regarding the implementation of surgical safety with the patient safety incident. The implementation of surgical safety shows that there was a significant association with incidents of patient safety. Surgical safety was carried out very well so that the findings of a patient safety incident was minimal. Keywords: Surgical Safety; Patient Safety Incident; Surgical; Patient Safety; Incident
The agency role of simulation models in model-building groups

Abstract Simulation models, in particular System Dynamics (SD) models, can be used in a group modelling setting to communicate, integrate, learn, collaborate, organize knowledge and derive new insights. Such models can play the roles of conceptual integrators, representations, learning or predictive tools. In this ethnographic study of two in-depth SD group modelling projects we discovered that SD models can be active agents in the group-model building process by initiating cognitive transition on participants’ (model and case based) modes of reasoning. We found that the cognitive transition was achieved through a series of surprises or shocks that refuted participants’ prior conceptions and forced them to switch between case-based and model-based reasoning during the model-building process. Based on these insights, we present a framework that describes how simulation models change the mode of reasoning in group modelling project and explains the model’s agency role. The study addresses the calls from earlier OR articles to contribute with more case studies using an ethnographic method looking into simulation artefact agency.
Assessing the Potential for Pyroconvection and Wildfire Blow Ups

Fire meteorologists have few tools for assessing atmospheric stability in the context of wildfires. Most tools at our disposal were developed for assessing thunderstorms and general convection, and so they ignore heat and moisture supplied by the wildfire. We propose a simple parcel-based model that can be used to assess how the atmosphere will affect a growing wildfire plume by also taking into account the heat and moisture released from the fire. From this model, we can infer trends in day to day atmospheric stability as it relates to fire plumes. We can also infer how significant the appearance of a pyrocumulus cloud on the top of a fire column is. In some cases, the appearance of a pyrocumulus indicates that the fire is near if not already blowing up, whereas in other cases environmental conditions remain too stable to have a significant effect. A qualitative application of the model is demonstrated through application to a 2017 wildfire case in Western Montana.
Health Believes and Willingness to Pay (WTP) for Social Health Insurance in Post Conflicts Fragile State South Sudan

Semi-Natural Areas on Post-Mining Brownfields as an Opportunity to Strengthen the Attractiveness of a Small Town. An Example of Radzionków in Southern Poland

The socio-economic and political changes of the end of the 20th century in Central and Eastern Europe had significant impacts on the transformation of urban spaces, especially in industrial and mining towns. The article attempts to explain the essence of these changes concerning the spatial development of—a small post-mining town in southern Poland. This article evaluates urban development policy in response to the significant land-use changes in the small post-mining city of Radzionków, with particular attention to the transformation of brownfield sites to semi-natural areas of regional importance. This issue is interesting for two reasons. First, this small city, located in a large European agglomeration, has to face competition focused on interesting regional projects. Second, there is a desire for reindustrialization as a remedy for job losses in mining and heavy industry. The successful establishment of a large botanical garden in this city provides a case study for discussing the future of small post-industrial cities and the development of land use policy regarding valuable natural areas located in post-industrial and post-mining areas. This study also indicates the vital role of the creative management factor.
A dual-arm manipulation strategy using position/force errors and Kalman filter

This paper presents a new coordination manipulation strategy for a custom-made dual-arm robot. With master and slave coordination infrastructure, both spatial relation and sense of touch are considered to hold an object stably. Given the known trajectory of the master arm, the slave arm fuses position and force commands by using the Kalman filter to yield optimal compensation amounts. The proposed strategy has been experimentally evaluated, and the results confirm that it was capable of dealing with fragile and flexible objects. In addition, the influence of the loop time of the digital controller on force control for this task was also investigated in mathematical and simulated ways. Furthermore, a series of experiments were designed to explore the effects that have influences on errors in force control. The main factors that affect force control error were analyzed.
