It is well known that the fate of transplanted tumors is controlled by the genetic relationship be tween the host and the tumor used for transplanta tion. This c@ncept has been accepted since the work of Little, Strong, Bittner, and others, as it has been reviewed by Bittner (1, 2), Little (5), Gorer (4), and Snell (9). In a study of some aspects of the growth of spontaneous and transplanted ma...

The stability of folded proteins is influenced by the intrinsic propensities of the amino acids to adopt particular secondary structural conformations. Although the statistically observed and experimentally measured propensities correlate well for both R-helices and â-sheets, the physicochemical basis of these propensities remains a topic of discussion.1-3 A correlation between â-sheet propensi...

Let A be an abelian variety,  be the dual abelian variety. The Fourier-Mukai transform is an equivalence between the derived categories of coherent sheaves Db(A) and Db(Â). Notice that there is a ”symplectic” line bundle LA on (Â×A)2, namely, LA = p14P⊗√∈∋P where P is the Poincaré line bundle on Â×A, such that the standard embeddings A ⊂ Â×A and  ⊂ Â×A are ”lagrangian” with respect to LA, i.e...

C —¿ > T transitions at CpG sites are the most prevalent mutations found in the p53 tumor suppressor gene in human colon tumors and in the germline (Li-Fraumeni syndrome). All of the mutational hot spots are methylated to 5-methylcytosine, and it has been hypothesized that the majority of these mutations are caused by spontaneous hydrolytic deamination of this base to thymine. We have previou...

â â â  â â â â â  abstract â  the research on social networks and collaborative strategies has highlighted from the mid of 1980 which has contributed to the success and development of firms. the relationship and communication with trade partners in overseas help success of firms in entering to foreign markets and improve new partners and new markets abroad. doing firm internationalization in fo...

In the Bargmann representation of quantum mechanics, physical states are mapped into entire functions of a complex variable z, whereas the creation and annihilation operators â and â play the role of multiplication and differentiation with respect to z, respectively. In this paper we propose an alternative representation of quantum states, conjugate to the Bargmann representation, where the rol...

since Φ̂(ω)Φ̂(−θ) = e−σ2(‖ω‖2+‖θ‖2)/4 = Φ̂(ω−θ)e−σ2(ω·θ∗+ω∗·θ)/4. (9) Assuming X is near equilibrium then, at reasonably low temperature, the power spectrum of the point configuration shows the bluenoise properties, i.e., has a delta at the origin and vanishes in an annulus around it. The approximation function Â(ω) equals to this function times Φ̂(ω) which is zero outside the angulus and hence Â(ω...

â â â  â â  abstract â  the importance of community's health followed by the consideration of endogenous growth models has led to an increase in health expenditure of countries to speed up economic growth and development. this has made the efficiency of health production function to an essential issue especially in developing countries. based upon this, the present study with employing the...
