Let }L
t{,t ∈ [0, 1], be a path of exact Lagrangian submanifolds in an exact symplectic manifold that is convex at infinity and of dimension
≥6. Under some homotopy conditions, an engulfing problem is solved: the given path }L
t{ is conjugate to a path of exact submanifolds inT
*Lo. This impliesL
t must intersectL
o at as many points as known by the generating function theory. Our Engulfing theorem depends deeply on a new flexibility property
of symplectic structures which is stated in the first part of this work.

It is of general knowledge that those (ultra)filter convergence relations coming from a topology can be characterized by two
natural axioms. However, the situation changes considerable when moving to sequential spaces. In case of unique limit points
Kisyński (Colloq Math 7:205–211, 1959/1960) obtained a result for sequential convergence similar to the one for ultrafilters, but the general case seems more difficult
to deal with. Finally, the problem was solved by Koutnik (Closure and topological sequential convergence. In: Convergence
Structures 1984 (Bechyně, 1984). Math. Res., vol. 24, pp. 199–204. Akademie-Verlag, Berlin, 1985). In this paper we present an alternative approach to this problem. Our goal is to find a characterization more closely related
to the case of ultrafilter convergence. We extend then the result to characterize sequential convergence relations corresponding
to Fréchet topologies, as well to those corresponding to pretopological spaces.

Aniline-mustard and its glucuronide conjugate were radioiodinated with 131I. The preliminary dynamic tests were carried out on rabbits. The scintigrams showed clearly that the glucuronide conjugate of aniline-mustard was very quickly cleared from the metabolism, accumulating in the bladder in about 15 minutes. The clearance time of radioiodinated aniline-mustard-glucuronide was considerably longer (about 45 min.). The results obtained from the biodistributional studies have represented interesting differences between the metabolic details of radioiodinated compounds, and indicated that the glucuronide conjugate of aniline-mustard may be a promising radioiodinated prodrug, if verification of its selective accumulation in some kinds of tumor cells can be obtained. 相似文献

The JINR (Dubna)-IN2P3 (France) Collaboration project aimed at the α, β γ, spectroscopy of the transfermium element isotopes using heavy-ion beams of the U-400 cyclotron and the modernized recoil
separator VASSILISSA was launched at Dubna. During the first full-scale experiment in September–October 2004, nobelium and
lawrencium isotopes produced in the 48Ca + 207,208Pb → 255,256No* and 48Ca + 209Bi → 257Lr* reactions were studied.

We compare the exact and perturbative results in two metrics and show that the spurious effects due to the perturbation method do not survive for physically relevant quantities such as the vacuum expectation value of the stress-energy tensor. 相似文献

Perturbative quantum chromodynamics (pQCD) predicts that the small-x gluons in a hadron wavefunction should form a color glass
condensate (CGC), characterized by a saturation scale Qs(x,A), which is energy and atomic number dependent. In this paper, we study the predictions of CGC physics for electron-ion
collisions at high energies. We consider that the nucleus at high energies acts as an amplifier of the physics of high parton
densities and estimate the nuclear structure function F2A(x,Q2), as well as the longitudinal and charm contributions, using a generalization for nuclear targets of the Iancu–Itakura–Munier
model that describes the ep HERA data quite well. Moreover, we investigate the behavior of the logarithmic slopes of the total
and longitudinal structure functions in the kinematical region of the future electron-ion collider eRHIC. 相似文献
