Retractile testes [1] Prepubertal boys can have an exaggerated cremasteric reflex. The testis may retract out of the scrotum in the cold, on examination, on excitement or on physical activity. It is normal and will descend when relaxed and warm, or it can be manipulated back into the scrotum. Retractile testes do not need any treatment but do need close follow-up until puberty, as they can beco...

A model-theoretic abstraction and treatment of the material in Section 2 of [Campana, Oguiso, and Peternell. Non-algebraic hyperkähler manifolds. Journal of Differential Geometry, 85(3):397–424, 2010] is given. The property of a finite rank type having all nontrivial fibrations almost internal to a given invariant set of types is introduced and explicated. As a consequence, on the complex-analy...

We give character formulae for the positive energy unitary irreducible representations of the N-extended D=4 conformal superalgebras su(2,2/N). Using these we also derive decompositions of long superfields as they descend to the unitarity threshold. These results are also applicable to irreps of the complex Lie superalgebras sl(4/N). Our derivations use results from the representation theory of...

Orientifolds of the type IIB superstring that descend from F theory and M theory orbifolds are studied perturbatively. One finds strong evidence that a previously ignored twisted open string is required in these models. An attempt is made to interpret the J type torsion in F theory where one finds a realization of Gimon and Johnson’s models which does not require these twisted strings. S-dualit...

We consider compact Riemannian manifolds (M,∂M, g) with boundary ∂M and metric g on which a finite group Γ acts freely. We determine the extent to which certain rigidity properties of (M,∂M, g) descend to the quotient (M/Γ, ∂/Γ, g). In particular, we show by example that if (M,∂M, g) is boundary rigid then (M/Γ, ∂/Γ, g) need not be. On the other hand, lens rigidity of (M,∂M, g) does pass to the...

We extend our previous results on the relation between quaternion-Kähler manifolds and hyperkähler cones and we describe how isometries, moment maps and scalar potentials descend from the cone to the quaternion-Kähler space. As an example of the general construction, we discuss the gauging and the corresponding scalar potential of hypermultiplets with the unitary Wolf spaces as target spaces. T...

introduction hydrops fetalis is a serious condition in fetal period, characterized by the presence of serous fluid accumulation in at least two potential spaces in fetus including pleural effusion, pericardial effusion, and ascites. the incidence of hydrops fetalis is one per 2500-3000 pregnancies. this condition is followed by different diseases. fetal hemolytic anemia and its hypoxemia due to...

When is a cause of a cause of an effect also a cause of that effect? The right answer is either “Sometimes” or “Always”. In favour of “Always”, transitivity is considered by some to be necessary for distinguishing causes from redundant noncausal events. Moreover transitivity may be motivated by an interest in an unselective notion of causation, untroubled by principles of invidious discriminati...
