Analysis Creative Thinking Ability of Student’s on the Topic of Momentum and Impulse in Senior High School

The capacity for creative thought is one of the skills that people in the 21st century need to have. Creative thinking ability refers to a person's ability to use their way of thinking to generate new ideas. Teachers must choose the best teaching strategy to provide pupils the chance to be creative. This study seeks to give a general picture of students' capacity for creatively thought about momentum and impulse. This study is quantitative and descriptive. As the research subjects, 57 students from classes XI MIPA 1 and XI MIPA 2 of SMA Negeri 1 Menggala participated in the study. The sample for this study was chosen using the cluster random sampling technique. A four-essay creative thinking exam with a reliability score of 0.610 and measures of fluency, flexibility, originality, and elaboration. The study's findings demonstrate that student have a considerable ability for creative thought. The indicator of fluency in thinking received the highest score of 54.67%, the indicator of flexibility of thinking was 47.2%, the indicator of originality was 34.93%, and the indicator of elaboration received the lowest proportion, 28.27%. This shows that students have the ability to develop different ideas in different ways, but they still have difficulty explaining these ideas

MorphoSys: efficient colocation of QoS-constrained workloads in the cloud

In hosting environments such as IaaS clouds, desirable application performance is usually guaranteed through the use of Service Level Agreements (SLAs), which specify minimal fractions of resource capacities that must be allocated for unencumbered use for proper operation. Arbitrary colocation of applications with different SLAs on a single host may result in inefficient utilization of the host’s resources. In this paper, we propose that periodic resource allocation and consumption models -- often used to characterize real-time workloads -- be used for a more granular expression of SLAs. Our proposed SLA model has the salient feature that it exposes flexibilities that enable the infrastructure provider to safely transform SLAs from one form to another for the purpose of achieving more efficient colocation. Towards that goal, we present MORPHOSYS: a framework for a service that allows the manipulation of SLAs to enable efficient colocation of arbitrary workloads in a dynamic setting. We present results from extensive trace-driven simulations of colocated Video-on-Demand servers in a cloud setting. These results show that potentially-significant reduction in wasted resources (by as much as 60%) are possible using MORPHOSYS.National Science Foundation (0720604, 0735974, 0820138, 0952145, 1012798

Coffee Bean Supply Chain Strategy : The Case of Trading Institution and Profit Margin For Pioneer Coffee in Indonesia

The role of coffee farmers is equally important to increase supply chain efficiency. The problem of this research is to propose a marketing channel strategy in the coffee bean supply chain by considering the position of farmers in the context of increasing profit margins. This study focused on Robusta coffee which is cultivated by many farmers in Jambi Province as one of the coffees producing regions in Indonesia. The research phase consists of observing supply chain practices and formulating mathematical models to calculate profit margins. There are two types of channel that has been practiced for a long time. The results of the profit margin analysis show that the best supply chain is the second channel and prove that a long supply chain is not efficient for marketing coffee beans because some activities are non-value added

Relativistic model of hidden bottom tetraquarks

The relativistic model of the ground state and excited heavy tetraquarks with hidden bottom is formulated within the diquark-antidiquark picture. The diquark structure is taken into account by calculating the diquark-gluon vertex in terms of the diquark wave functions. Predictions for the masses of bottom counterparts to the charm tetraquark candidates are given.Comment: 6 page

Protein-Ligand Scoring with Convolutional Neural Networks

Computational approaches to drug discovery can reduce the time and cost associated with experimental assays and enable the screening of novel chemotypes. Structure-based drug design methods rely on scoring functions to rank and predict binding affinities and poses. The ever-expanding amount of protein-ligand binding and structural data enables the use of deep machine learning techniques for protein-ligand scoring. We describe convolutional neural network (CNN) scoring functions that take as input a comprehensive 3D representation of a protein-ligand interaction. A CNN scoring function automatically learns the key features of protein-ligand interactions that correlate with binding. We train and optimize our CNN scoring functions to discriminate between correct and incorrect binding poses and known binders and non-binders. We find that our CNN scoring function outperforms the AutoDock Vina scoring function when ranking poses both for pose prediction and virtual screening

Solvent primitive model of an electric double layer in slit-like pores: microscopic structure, adsorption and capacitance from a density functional approach

We investigate the electric double layer formed between charged walls of a slit-like pore and a solvent primitive model (SPM) for electrolyte solution. The recently developed version of the weighted density functional approach for electrostatic interparticle interaction is applied to the study of the density profiles, adsorption and selectivity of adsorption of ions and solvent species. Our principal focus, however, is in the dependence of differential capacitance on the applied voltage, on the electrode and on the pore width. We discuss the properties of the model with respect to the behavior of a primitive model, i.e., in the absence of a hard-sphere solvent. We observed that the differential capacitance of the SPM on the applied electrostatic potential has the camel-like shape unless the ion fraction is high. Moreover, it is documented that the dependence of differential capacitance of the SPM on the pore width is oscillatory, which is in close similarity to the primitive model.Comment: 10 pages, 5 figure

Charge storage in nanotubes: the case of a 2-1 electrolyte

We consider a 2-1 electrolyte in contact with a narrow nanotube, which only allows one-dimensional storage along the axis. The asymmetry does not allow an a priori definition of the potential of zero charge; instead, the natural reference is the electrode potential at which both ions have the same electrochemical potential; the value of the latter can serve as a measure of ionophilicity. Near this potential, ionophobic tubes are filled with a dilute gas, ionophilic tubes are filled with a one-dimensional solid containing about the same number of the divalent ions and the monovalent counterions, a structure that is stabilized by a strong screening of the Coulomb interaction by an induced counter charge on the walls of the tube. The filling of the tube by the application of an electrode potential exhibits a complicated pattern of interactions between the two kinds of ions.Comment: 7 pages, 6 figure

Diverse Education Based on Specific Conditions in Rural Areas of China

Connecting the spiritual outlook of the future society, education is the cornerstone of the rejuvenation of a nation. By the year 2018, nearly 600 million people lived in rural areas of China. For being such a large group, their basic necessities of life, and each and every move are closely related to the country’s destiny. So when these two parts get associated, the problem become larger and more difficult. Nowadays we should view the rural education with new eyes. Affected by the deepening of the market economy, the expansion of higher education and the tough job market, rural residents’ views on education are changing and can gradually be divided into two categories: the one is that education is the steering wheel which can lead to the change of fate; the other one is that the education is no longer the only way out. The cost of continuing a child’s education must be seen first.This article holds that in the process of revitalizing rural education, we should take measures according to local conditions basing on rural characteristics, and attach importance to the development of a multi-level and diverse education so that students can see more possibilities besides study and work, which will not only benefit the development of individuals, but also contribute to the progress of the whole society
