Relative Hilbert Scheme of Points

Let $D$ be a smooth divisor on a non singular surface $S$. We compute Betti numbers of the relative Hilbert scheme of points of $S$ relative to $D$. In the case of \PP^2 and a line in it, we give an explicit set of generators and relations for the cohomology groups of this space.Comment: The final version has been published in the Journal of the Mathematical Society of Japa

THE SUPREMACY OF WHITE PEOPLE IN HARRIET BEECHER STOWE’S UNCLE TOM’S CABIN OR LIFE AMONG THE LOWLY AS A CHILDREN’S LITERATURE

This research aims to identify White supremacy in the Uncle Tom’s Cabin as a children’s literature and to understand how it is constructed in the novel as well as the danger of it. The theory of White Supremacy by Frederickson and racial differences in colonial and postcolonial societies by Fanon are used to answer the objectives. This research was qualitative in nature and a descriptive-qualitative method was used to analyze the data. The main source of this research was a novel entitled Uncle Tom’s Cabin or Life Among The Lowly by Harriet Beecher Stowe. The data were phrases, clauses, sentences, and expressions related to White Supremacy and the construction of it found in the novel. The data analysis was conducted through six steps: identifying, reading and re-reading, coding and categorizing, and sorting the data, making the interrelation between the description of the data and the theory, and making an interpretation of the findings. To obtain trustworthiness, the researcher used intra-rater technique and peer debriefing method. The findings of this research show that there are two categories of White supremacy that match the kinds of White supremacy portrayed in the novel. Those two categories are White supremacy in the religious context and in the political context. First, it can be seen that the novel depicts the desirability of teaching Christianity to Blacks and to show White supremacy through the use of religion and political messages embedded in the novel. Second, it is to recognize in what way white supremacy is constructed in the novel. The next findings are derived from Fanon’s theory of racial difference in colonial and postcolonial societies. There are three forms of construction of white supremacy that can be identified from the novel. The three categories are the use of language, stereotypes, and the symbolization. The discussion includes the implication of the danger of White supremacy in the insight of children’s literature. As it is understood from the findings that although Uncle Tom’s Cabin is considered an antislavery literary work, it does not mean that Blacks are meant to be equal and belong to America

Three-dimensional modeling of single stranded DNA hairpins for aptamer-based biosensors.

Aptamers consist of short oligonucleotides that bind specific targets. They provide advantages over antibodies, including robustness, low cost, and reusability. Their chemical structure allows the insertion of reporter molecules and surface-binding agents in specific locations, which have been recently exploited for the development of aptamer-based biosensors and direct detection strategies. Mainstream use of these devices, however, still requires significant improvements in optimization for consistency and reproducibility. DNA aptamers are more stable than their RNA counterparts for biomedical applications but have the disadvantage of lacking the wide array of computational tools for RNA structural prediction. Here, we present the first approach to predict from sequence the three-dimensional structures of single stranded (ss) DNA required for aptamer applications, focusing explicitly on ssDNA hairpins. The approach consists of a pipeline that integrates sequentially building ssDNA secondary structure from sequence, constructing equivalent 3D ssRNA models, transforming the 3D ssRNA models into ssDNA 3D structures, and refining the resulting ssDNA 3D structures. Through this pipeline, our approach faithfully predicts the representative structures available in the Nucleic Acid Database and Protein Data Bank databases. Our results, thus, open up a much-needed avenue for integrating DNA in the computational analysis and design of aptamer-based biosensors

The Determinants of Trade Balance and Adjustment to the Crisis in Indonesia

This paper investigates the effects of real exchange rate depreciation and supply side shocks on exports and imports. Indonesia provides an interesting case study of the subject because this country experienced a large depreciation, banking sector collapse, and socio-political turbulence during the Asian crisis episode. The results suggest that trade balance will improve following devaluation through an increase in exports and a collapse in imports. Because the elasticity of imports with respect to the real exchange rate is greater than that of exports, improvement in trade balance would be mainly come from import compression. It is also found that export performance could have been far better if Indonesia did not suffer from banking problems and socio-political turbulence.Real Exchange Rate, Export, Import, Indonesia.
