Using foxtail millet (Setaria italica (L.) Beauv.) male-sterile line 1066A as female parent and Yugu 1 primary trisomic series (1 - 7) and tetrasomics 8, 9 as male parents, chromosome location of gene for male-sterility and yellow seedling in line 1066A was studied by primary trisomic analysis. The plants of F-1 generation of trisomics 2 - 9 were obtained by crossing with a great many plants of 1066A. F-1 generation of trisomics was similar to their male parent in morphologic characters, the color of their seedling was green, and pollen was partially fertile. The segregation ratio of fertility to sterility is 3:1 in F-2 generation of trisomics 2, 3, 4, 5, 7, 8 and 9; and 14:1 only in F-2 generation of trisomic 6 (chi(0.05)(2) = 0.012). The segregation ratio of green seedling to yellow seedling is 12:1 only in F-2 generation of trisomic 7 (chi(0.05)(2) = 0.31), but in other cases, this ratio is 3:1. The results indicated that the male-sterility gene was located on chromosome 6, and the gene for yellow seedling was monogenic recessive and located on chromosome 7. The rate of trisomics transmission by pollen was tested, trisomics 8 and 9 were the highest in rates of trisomics transmission and followed by trisomics 6 and 4. 展开更多

The behavior of wheat-rye translocation chromosome and alien chromosome including Thinopyrum and Haynaldia chromosome at meiosis was investigated in two hybrids by fluorescence in situ hybridization (FISH). Misdivision of translocation chromosome at anaphase I and rye chromatin micronucleus at tetrad stage were observed, A plant with one normal 1BL/1RS translocation chromosome and one 1BL/1RS translocation chromosome deleted about 1/3 of rye chromosome arm in length was identified. One plant with wheat-Thinopyrum non-Robertson translocation chromosome was also detected in the F-2 population of Yi4212 x Yi4095. That could be the results of unequal misdivision of wheat-rye 1BL/1RS translocation chromosome and Thinopyrum chromosome during meiosis. No interaction between translocation chromosome and alien chromosome at meiosis was supported by the data of the distribution frequencies of translocation chromosome and Thinopyrum or Haynaldia chromosome in the progeny of two hybrids. The results may be useful to cultivate new germplasms with different length of rye 1R short arm and wheat-alien non-Robertson translocation tines under wheat background. 展开更多

Role based access control is one of the widely used access control models.There are investigations in the literature that use knowledge representation mechanisms such as formal concept analysis(FCA),description logics,and Ontology for representing access control mechanism.However,while using FCA,investigations reported in the literature so far work on the logic that transforms the three dimensional access control matrix into dyadic formal contexts.This transformation is mainly to derive the formal concepts,lattice structure and implications to represent role hierarchy and constraints of RBAC.In this work,we propose a methodology that models RBAC using triadic FCA without transforming the triadic access control matrix into dyadic formal contexts.Our discussion is on two lines of inquiry.We present how triadic FCA can provide a suitable representation of RBAC policy and we demonstrate how this representation follows role hierarchy and constraints of RBAC on sample healthcare network available in the literature. 展开更多

Thermodynamic models of calculating mass action concentrations for structural units or ion couples in RbCl-H2O binary and RbCl-RbNO3-H2O ternary strong electrolyte aqueous solutions were developed based on the ion and molecule coexistence theory at 298.15 K.A transformation coefficient is needed to compare the calculated mass action concentration and the reported activity because they are obtained at different standard states and concentration units.The results show that the transformation coefficients between the calculated mass action concentrations and the reported activities of the same structural units or ion couples in RbCl-H2O binary and RbCl-RbNO3-H2O ternary strong electrolyte aqueous solutions change in a very narrow range.The transformed mass action concentrations of structural units or ion couples in RbCl-H2O binary system are in good agreement with the reported activities. The transformed mass action concentrations of RbCl and RbNO3 in RbCl-RbNO3-H2O ternary solution are also in good agreement with the reported activities,aRbCl and 3RbNOa,with different total ionic strengths as 0.01,0.05,0.1,0.5,1.0,1.5,2.0,3.0 and 3.5 mol/kg,respectively.All those results mean the developed thermodynamic model of strong electrolyte aqueous solutions can reflect structural characteristics of RbCl-H2O binary and RbCl-RbNO3-H2O ternary strong electrolyte aqueous solutions and the mass action concentration also strictly follows the mass action law. 展开更多

This paper presents the estimation of three-dimensional volumetric errors of a machining center by using a tracking interferometer. A tracking interferometer is a laser interferometer with the mechanism to steer the laser direction to follow a target retroreflector. Based on the triangulation principle, the three-dimensional position of the target can be estimated from measured laser displacements. Its capability to measure three-dimensional positioning errors for arbitrary trajectories is important for the indirect measurement of the machine's kinematic model. This paper presents experimental investigation of the estimation accuracy of the multilateration-based measurement by a tracking interferometer. A tracking interferometer developed by a part of the authors is used in experiments. In the present experiment, the measured volume of target positions was 100 mm × 100 mm × 100 mm. The estimation accuracy of targets within this volume was not sufficiently high compared to the positioning error of the measured machine tool. The results of the experiment and simulation show that the estimation uncertainty is dependent on tracking interferometer locations relative to target locations. Error sensitivity analysis shows that wider distribution of tracker positions in XY improves the estimation accuracy. 展开更多

This essay suggests an unlikely encounter between the recent thinker of the deconstruction of speeches, Jacques Derrida, and the medieval constructor of theological speeches, Saint Anselm. The common motto is the idea of gift. The gift of the death of Christ in the economy of salvation is the target of Derrida's deconstruction. Anselm himself enables this. However, there is in Anselm's theology of Trinity a metaphysics of the gift of being and of being other, elaborated with regard to the procession of the Holy Spirit. And it is possible to submit the original gift of the Holy Spirit to the same kind of deconstruction, that is, of economic reduction, to which the gift of the death of Christ had been submitted. But both the construction and the deconstruction of the theology of gift resort to the same kind of analogy procedure. And economy does not enable us to think the gift as purely as does theology. 展开更多

There are philosophers and logicians who do think that the Trinity-triangle makes up an evident formal-logic inconsistency demonstrating convincingly that Christian faith is illogical and hence irrational one. The present paper submits a systematic counter-argumentation against such thinking. According to the submitted counter-arguments, there is no formal-logic inconsistency in the Holy-Trinity-triangle: There is only a logic-linguistic illusion of such inconsistency which illusion is naturally produced by the ambiguity of the word "is" in natural language. The author has invented an effective remedy for that illusion, namely, a precise formulation of the generalized and thus modernized Guillotine of Hume by means of an artificial language of two-valued algebraic system of formal ethics of moral rigor. Systematical using the mathematized formulation of the generalized Hume's Guillotine cuts down the mentioned linguistic illusion of logical inconsistency. Thus, the paper essentially interconnects discrete mathematical representations of formal iogic of thinking and formal ethics of acting. In relation to contemporary symbolic logic, the author submits not a technical result solving some important particular problem concerning some specific system of symbolic logic but a significantly new result of conceptual work concerning logic in general and its interconnection with mathematical ethics. The old idea of logic as a moral science is transformed into a novel idea of symbolic logic as a brunch of mathematical ethics. In particular, two-valued algebra of classical formal logic is considered as a particular case of two-valued algebra of formal ethics of moral rigor. The submitted conception of logic is instantiated by applying it to the knotty logic-problem of Holy-Trinity-triangle. 展开更多

The significance of the trinity archetype and the number three is recurrent in religions and myths around the world Within the trinity archetype, each element is both distinct from and symbiotic with the other elements--that is to say, each stands apart from the others, but none can truly function alone. This can be seen throughout Greek mythology, for example, The Moirae and The Musai, and of eourse, through the Christian Trinity of Father, Son, and Holy Spirit. While the archetype of the trinity appears numerous times throughout the Potter series, at its very heart, the series is centrally focused on a triad of trinities: the Trio (Harry, Ron, and Hermione), the three Unforgivable Curses, and the three Deathly Hallows. It is the intersection of this triad of trinities--this "supertrinity"--that not only drive the Potter narrative, but connect the work so readily to the psyche of readers and fans; it is how we are harmonically programmed, in terms of understanding stories. 展开更多

The "Tree of Death" is a metaphor I use to unlock my Christian assumptions on how the dead attain eternal existence in the afterlife state. The tree's unconcealedness, in this life and presumably the next, along with the moral habits an agent develops in this life explain the obstinacy of the dead, that is, how the agent's irrevocable decision to side with the God of Abraham, or not, is possible. For that to be the case, the existential relationships that generate personal identity in this life must accompany (individuate) the subject in the next life. In Christian philosophy, the person-making process mirrors the relationships of the Blessed Trinity. While Martin Heidegger is not a Christian philosopher, his view on truth and being's unconcealedness provides a useful piece of the argument to continue the Thomistic case for personal immortality. Heidegger is not a catholic philosopher, but the focus he places on being's unconcealedness is consonant with the focus Thomas Aquinas puts on the intelligibility of being. While Heidegger's discussion of being is rooted in Dasein's finitude, the Thomistic interpretation of being situates unconcealedness within the perspective of God's creative act. His vision resets the possibility of applying Heidegger's fundamental ontology beyond temporality. The paper develops through a discussion of the Tree's "branches, trunk, and roots" to conclude that the Christian perspective transforms Heidegger's view of death into "the ultimate possibility of possibility." 展开更多

In spite the fact that Emily Elizabeth Dickinson lived during the 19th century Amherst among conservative community that gave less chance to female voice to gain a share in social and political life, she paved the way for the coming female thinkers to obtain more freedom of thought and expression. In other words, since she was convient that "Abdiction of Belief makes the Behaviour Small", she undercut social conventions and moved under gradual shift from Orthodox Trinitarianism into new thoughts of liberalism. However, in good deal of her work, she still pertains to religious conservatism in wider sense than Amhest Church had been dectated. 展开更多

This paper makes a detailed analysis of Course Schedules (2013-2014) of College English in four universities of C9 League, which reveals that ESP courses are much less than EGP courses, even in the top universities in our country, and that the implementation of ESP teaching is hindered for many reasons. Therefore, based on the rapid development of MOOC and the one-size-fits-one guideline of college English teaching, the preferences of ESPMOOC have been illustrated, and the framework to practice trinity ESP teaching mode has been explicitly depicted. The mode refers to the combination of traditional classroom teaching, flipped teaching on aid of MOOC, and autonomous MOOC learning under the condition that ESP teaching group is elaborately set up and 2-band ESP teaching is preferably promoted. 展开更多

Based on a synthetic geological study of drilling,well logging and seismic data,core observations and geochemical analysis,it is recognized that Triassic sedimentary facies in the Tahe area of Tarim Basin include braided river deposits filling erosional valleys,and sublacustrine fan,canyon and delta facies.Braided river deposits filling erosional valleys are dominated by coarse-grained lithic quartz sandstone with oblique bedding,and represent the most important sedimentation type of sandstone in the study area.Sublacustrine fan and canyon facies are mainly distributed in the Middle Oil Member.Most delta sediments are deposited in highstand system tract(HST),Because of frequent changes in base level,delta sediments are commonly eroded and rarely preserved.Sedimentary cycles are clearly reflected by lithology,sedimentary structures and well logging data,and are closely related to the changes in lacustrine level.In accordance with the basic principle of sequence subdivision,seven type-I boundaries can be recognized in Triassic strata and six type-I sequences are subdivided correspondingly.In general,lowstand system tract(LST) is well developed within stratigraphic sequences and forms the main body of reservoir sandstone in this area;highstand system tract(HST) and transgressive system tract(TST) are often eroded by upper sequences or missed,Although various factors have different influences on terrestrial sequence stratigraphy,the classical sequence stratigraphy theory proposed by VAIL can be applied to terrestrial strata. 展开更多

The c-axis charge transport of the hole doped triangular antiferromagnet is investigated within the t-J model by considering the incoherent interlayer hopping. It is shown that the c-axis charge transport of the hole doped triangular antiferromagnet is essentially determined by the scattering from the in-plane fluctuation. The c-axis conductivity spectrum shows a low-energy peak and the unusual high-energy broad band, while the c-axis resistivity is characterized by a crossover from the high temperature metallic-like behavior to the low temperature insulating-like behavior, which is qualitatively consistent with those of the hole doped square lattice antiferromagnet. 展开更多

Properties of the triaxial superdeformed (TSD) bands of odd-A Lu isotopes are investigated systematically within the supersymmetry scheme including many-body interactions and a perturbation possessing the S0(5) (or SU(5)) symmetry on the rotational symmetry. Quantitatively good results of the γ-ray energies, the dynamical moments of inertia and the spin of the TSD bands in odd-A Lu isotopes are obtained. The calculation shows that the competition between the pairing and anti-pairing effects exists in these TSD bands. Meanwhile, the SU(3) symmetry in TSD bands are broken more seriously than in superdeformed (SD) bands. 展开更多
