This study discusses the basic guarantee of the Charter of the United Nations to realize the right to development from the angle of Transforming Our World: the 2030 Agenda for Sustainable Development. The concepts regarding the people as the focal point, the dignity, the worth of the human being, as well as larger aspects of freedom, and other basic concepts within the Charter of the United Nations, guide the right direction of action for the realization of the right to development. The purpose and principles of the United Nations establishment in the Charter constitute the basic legal protection of the right to development. Values of peace, international dialogue, and international cooperation show the right path to the realization of the right to development. 展开更多

By using c-Ha-ras-1, N-ras Wigler (left sequence) and P52C.(right sequence), c-sis, v-erbB, c-myc and v-fos oncogenes as probes, restriction fragment length polymorphisms (RFLPs) of tumor tissue DNAs of 95 patients with gastric carcinoma, primary hepatic carcinoma and brain tumor, and those of 90 normal individuals were studied with the techniques of Southern blot and dot blot. Gene amplification and recombination were also examined in some tumors simultaneously. Some alleles of oncogene are reported in Chinese population for the first time. Moreover, the characteristic frequency of some "rare" alleles and genotypes occurred in some tumor samples is significantly higher than that occured in normal individuals. Pedigree analysis for 2 patients showed that some "rare" alleles are also abandant. Besides, gene amplification and recombination were found in some tumors. 展开更多

In the contemporary world, various political actors, both within and outside of states, have continued to break through subjective and objective constraints to participate more and more widely in the political activities of the world society, which has promoted inclusiveness in the relationship between all actors and fostered reconciliation between man and nature. Historically, the political development of the world has followed two routes: one involves inter-personal relationships, which have evolved gradually through violent and non-violent forms of revolution from one marked by the conflict between the oppressed and the oppressors and between the exploited and the exploiters, to one marked by equality and mutual respect; and the other involves the progress of the forms of production organization and society made possible by the productive forces driving the production relations forward and the change to the economic foundation that forced the superstructure to experience fundamental transformation. The latter is fundamental and recessive, while the former is dominant, which has a direct impact on states and the broader world. In such a progressive evolution, the political transformation of the world has gradually changed from a violent one to a more peaceful one, and the grander trend has changed from having the features of national independence and liberation as well as a people's revolution, to having the features of seeking development in an all-around way and forging a harmonious world free from threat, fear and anxiety.Hereinto, the dominant role of rational human self-restraint is becoming more and more obvious, with which the actors, even those who onceopposed each other, are seeking mutual tolerance, acceptance and cooperation, including human respect for nature and the environment. In essence, this is indicative of the emancipation of human sociality and the reconciliation between man and nature, which is still currently under way. 展开更多

An effective near-field - far-field (NF - FF) transformation with spherical scanning for quasi-planar antennas from irregularly spaced data is developed in this paper. Two efficient approaches for evaluating the regularly spaced spherical samples from the nonuniformly distributed ones are proposed and numerically compared. Both the approaches rely on a nonredundant sampling representation of the voltage measured by the probe, based on an oblate ellipsoidal modelling of the antenna under test. The former employs the singular value decomposition method to reconstruct the NF data at the points fixed by the nonredundant sampling representation and can be applied when the irregularly acquired samples lie on nonuniform parallels. The latter is based on an iterative technique and can be used also when such a hypothesis does not hold, but requires the existence of a biunique correspondence between the uniform and nonuniform samples, associ- ating at each uniform sampling point the nearest irregular one. Once the regularly spaced spherical samples have been recovered, the NF data needed by a probe compensated NF - FF transformation with spherical scanning are efficiently evaluated by using an optimal sampling interpolation algorithm. It is so possible to accurately compensate known posi- tioning errors in the NF - FF transformation with spherical scanning for quasi-planar antennas. Some numerical tests assessing the accuracy and the robustness of the proposed approaches are reported. 展开更多

Chronic eosinophilic leukemia (CEL) is a rare disorder that is characterized by hypereosinophilia with increased number of blood or marrow blasts (>5% and <20%). CEL is distinguished from hypereosinophilic syndrome (HES) by the presence of eosinophilic clonality. Chronic eosinophilic leukemia not otherwise specified (CEL-NOS) diagnosis is made when no fusion genes are detected by most modern molecular testing, particularly the most common fusion gene FIP1L-1/PDGFRA (Factor Interacting with PAP like-1/Platelet-Derived Growth Factor Receptor Alpha). This disease is very rare, and its description in the literature is not well characterized. We report a fetal case of severe CEL-NOS in a 19-year-old male who presented with a plethora of clinical features consists of constitutional symptoms, pancytopenia, intravascular thrombosis, acute stroke and endomyocardial infiltrates. The course of his disease was aggressive and resistant to conventional treatment. After a short period of improvement, an acute transformation into blast crisis (BC) had occurred. The diagnosis was confirmed by morphology and immunophenotyping of bone marrow biopsy. The patient eventually died of heart failure and sepsis. To our knowledge this is the first case report of fatal CEL-NOS transforming into severe blast crisis. 展开更多
