In this short paper, uncertainties on resource stock and on technical progress are introduced into an intertemporal equilibrium model of optimal extraction of a non-renewable resource. The representative consumer maximizes a recursive utility function which disentangles between intertemporal elasticity of substitution and risk aversion. A closed-form solution is derived for both the optimal ext...

Translocation is one of the most frequently occurring human chromosomal aberrations. The constitutional t(11;22)(q23;q11), which is the only known recurrent non-Robertsonian translocation, represents a good model for studying translocations in humans. Here we demonstrate polymorphisms of the palindromic sequence at the t(11;22) breakpoint that affect the frequency of de novo translocations in s...

Based on SERVAUALmodel, this paper brings in the entropy method to rank quality improvement (QI) priority for service attributes, and a service quality evaluation(SQE) model integrating competitive analyses has been structured to evaluate the mobile communication service quality (SQ) for Wuhan Branch of China Telecom(WBCT). The research shows that the QI priority of 22 service attributes has ch...

Theorem 1 Suppose X is a smooth toric Fano 4-fold. Then X admits a totally nondegenerate abelian surface if X = P4, if X = P1 × P3 (type B4), or if X is a product of two smooth toric Del Pezzo surfaces (i.e. of type C4, D13, H8, L7, L8, L9, Q10, Q11, K4, U5, S2 × S2, S2 × S3 or S3 × S3). Otherwise there is no such embedding, unless possibly X is of type C3, D7, D10, D11, D14, D17, D18, G3, G4, ...

A rare case of variant Philadelphia (Ph1) chromosome positive [46, XX, t (9; 22) (q34; q11), inv (9) (9q22; 22q13)] chronic myelocytic leukemia (CML) was described. The patient, 73 years old female, was hospitalized to our hospital because of leukocytosis. Hematological findings corresponded to those of CMLs. However, this case lacked hepatosplenomegaly. Southern blot analysis using a 3 breakpo...

There are three fundamental bias currents to be chosen for this novel transimpedance stage: the collector current of the emitter followers Q8 and Q9, that of the common-emitter transistors Q10 and Q11, and finally the current in the folded cascodes formed by Q14 and Q15. Needless to say, the collector current of complementary pairs (e.g., Q8 and Q9) should be set to approximately equal values. ...
