A simple proof is given of the following particular case of the DanielMoore conjectures, recently proved in full generality by Wanner, Hairer and Nersett. The maximum error order achievable by an A-stable k-step two-derivative formula equals four and the optimum value of the corresponding error constant is achieved by the second Obrechkoff method. The arguments presented in this paper reveal so...

All.trans retinoic acid (RA) is the first highly effective differentiation inducing agent for remission induction in patients with acute promyelo.. cytic leukemia. However, remissions are short-lived because the treatment fails to induce complete differentiation and fails to eradicate the malignant clone. To eliminate rapidly the malignant clone, in analogy with aggressive chemotherapy, the com...

Consider the frequency synchronization in global niobile satellite coiiiniunications systems. Let fc ( n , %: t ) be the t,raiismitt,ed ca.rrier frequency from the SAN t o the i-th user in the n-th spot bea.m, D c ( t ) be the fractional Doppler of t.he feeder link, fc6 be t,he translation frequency at. t.he sat.ellit,e, J f ( t ) be the fractional satel1it.e translation error, atid D,(n , i , ...

We have sequenced DNA clones corresponding to the entire coding and 5' untranslated regions and almost all of the 3' untranslated region of a silkmoth chorion RNA which is expressed largely in a subpopulation of follicular epithelial cells (aeropyle crown region). This RNA encodes the El protein, one of two components of the prominent "ifiler" that helps mold the shape ofaeropyle crowns. The co...

This in vitro study investigated strain produced in the placement and polymerization of Class II posterior composite resin restorations in primary teeth. Mesio-occlusodistal preparations were placed in primary teeth, followed by posterior composite resin restoration placement, using 3 different application techniques (technique I--placement and polymerization in 1 complete unit; technique II--p...

We studied left ventricular performance and contractility after volume loading in lambs at 122 days (group I, n = 9) and 139 days gestational age (group IL, n = 9) and in 8-day-old full-term lambs (group III, n = 7). All were mechanically ventilated; each preterm lamb was treated with surfactant to stabilize pulmonary function and the ductus arteriosus was occluded with an inflated catheter bal...

We develop an axiomatic approach to the theory of Sobolev spaces on metric measure spaces and we show that this axiomatic construction covers the main known examples (Hajtasz Sobolev spaces, weighted Sobolev spaces, Upper-gradients, etc). We then introduce the notion of variational p-capacity and discuss its relation with the geometric properties of the metric space. The notions of p-parabolic ...

The mechanism of the Counter Scheme (CS) has been shown to be an effective statistical approach for the reorganization of linear lists, where the records in the list are referenced independently with a time homogeneous multinomial distribution. In this paper we show that derivative schemes can be used effectively in other contexts as well. Specifically, we consider (a) linear lists that are dou...
