Classical works

The limits of current micro-scale technology is approaching rapidly. As the technology is going toward nano-scale devices, physical phenomena involved are fundamentally different from micro-scale ones. Principles in classical physics are no longer powerful enough to explicate the phenomena involved in nano-scale devices. At this stage, quantum mechanic sheds some light on those topics which cannot be described by classical physics. The primary focus of this research work is the development of an analysis technique for understanding the behavior of strongly perturbed harmonic oscillators.

Teaching class works for students majoring in political education plays a crucial role in training curriculum. This research paper discusses using flipped classroom model to replace the traditional one in teaching the above mentioned subject in order to form students’ essential personalities and competencies to meet the need of education innovation cause.

We reported the isolation and identification of the antraquinones, aloe-emodin and rhein from the leaves of Cassia alata L., Caesalpiniaceae growing in Daoai, Lamdong. In the previous work, we reported that flavonoid kaempferol had been isolated from the leaves of this tree. Now, we continue to reporte two antraquinones: aloe-emodin and rhein which were separated by two methods: classical column chromatography and preparative thin layer chromatography. Their structures were identifed by spectra such as: IR, UV, 1 H-NMR, 13 C-NMR, MS and mp.

Đảo ngữ đề cập tới hiện tượng động từ không theo qui tắc trong câu. Trong trường hợp này, dạng thức nghi vấn (có cấu trúc: trợ động từ + chủ ngữ + động từ chính) nằm ngay trong cấu trúc câu khẳng định (ví dụ: He goes to work every day). Dưới đây là một vài ví dụ về câu đảo ngữ: Not only do I enjoy classical music, but I also enjoy Pop music. (Tôi không chỉ thích nhạc cổ điển mà tôi còn thích nhạc Pop)....

The molecular mechanisms of the DNA mismatch repair (MMR) system have been uncovered over the last decade, especially in prokaryotes. The results obtained for prokaryotic MMR proteins have provided a frame-work for the study of the MMR system in eukaryotic organisms, such as yeast, mouse and human, because the functions of MMR proteins have been conserved during evolution from bacteria to humans.

All Tangled Up knitting from across the pond Kiri Kiri is a triangular shawl, with fern motif, garter stitch border and scalloped edging. Knit in Rowan Kid Silk haze, it has a gossamer effect which belies its warmth. The pattern uses 3 balls of KSH, at 75 grams, it's the perfect shawl to wear throughout the year The Fern motif is a classic Shetland motif that works well either on its own or as a panel within a larger design. I have adapted the original design used by Sharon Miller in her Birch shawl for Rowan, to make the pattern easier for new...

We obtain global well-posedness, scattering, and global L10 spacetime t,x bounds for energy-class solutions to the quintic defocusing Schr¨dinger equao tion in R1+3 , which is energy-critical. In particular, this establishes global existence of classical solutions. Our work extends the results of Bourgain [4] and Grillakis [20], which handled the radial case.

We prove that the classical Oka property of a complex manifold Y, concerning the existence and homotopy classification of holomorphic mappings from Stein manifolds to Y, is equivalent to a Runge approximation property for holomorphic maps from compact convex sets in Euclidean spaces to Y . Introduction Motivated by the seminal works of Oka [40] and Grauert ([24], [25], [26]) we say that a complex manifold Y enjoys the Oka property if for every Stein manifold X, every compact O(X)-convex subset K of X and every continuous map f0 : X → Y which is holomorphic in an...

The interplay between geometry and topology on complex algebraic varieties is a classical theme that goes back to Lefschetz [L] and Zariski [Z] and is always present on the scene; see for instance the work by Libgober [Li]. In this paper we study complements of hypersurfaces, with special attention to the case of hyperplane arrangements as discussed in Orlik-Terao’s book [OT1]. Theorem 1 expresses the degree of the gradient map associated to any homogeneous polynomial h as the number of n-cells that have to be added to a generic hyperplane section D(h) ∩ H to obtain the complement in...

Surfaces of sections are a classical tool in the study of 3-dimensional dynamical systems. Their use goes back to the work of Poincar´ and Birkhoff. e In the present paper we give a natural generalization of this concept by constructing a system of transversal sections in the complement of finitely many distinguished periodic solutions. Such a system is established for nondegenerate Reeb flows on the tight 3-sphere by means of pseudoholomorphic curves.
