Mark Schneider is Professor of Political Science at the State University of New York, Stony Brook. He has written widely on education policy. His last book Choosing Schools: Consumer Choice and the Quality of American Schools (written with Paul Teske and Melis sa Marschall) was published by Princeton University Press in 2000 and won the 2002 Aaron Wildavsky Best Book Award from the Policy Studi...

Introduction: Although some CR chondrites are recognized to be among the most pristine meteorites [1], other members of this group are heavily hydrated [e.g. 2]. However, no evidence of thermal metamorphism has been documented for this group. Antarctic fall GRA 06100, initially classified as a CR2 chondrite have not been previously studied. We use optical microscopy, SEM, and focused beam EPMA ...

The asymmetric unit of the title compound, [Cr(C2O4)(C10H24N4)]2[Cr2O7]·8H2O (C10H24N4 = 1,4,8,11-tetra-aza-cyclo-tetra-decane, cyclam; C2O4 = oxalate, ox) contains one [Cr(ox)(cyclam)]+ cation, one half of a dichromate anion that lies about an inversion centre so that the bridging O atom is equally disordered over two positions, and four water mol-ecules. The terminal O atoms of the dichromate...

A robust superamphiphobic sponge (SA-sponge) is proposed by using a single initiated chemical vapor deposition (i-CVD) process. Poly(3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,10-heptadecafluorodecyl methacrylate) (PFDMA) is deposited on a commercial sponge by the polymerization of fluoroalkyl acrylates during the i-CVD process. This PFDMA is conformally coated onto both the exterior and interior of the...

The chromium isotope system (53 Cr/52 Cr expressed as δ53 Cr relative to NIST SRM 979) is potentially a powerful proxy for the redox state of the ocean-atmosphere system, but a lack of temporally continuous, well-calibrated archives has limited its application to date. Marine carbonates could potentially serve as a common and continuous Cr isotope archive. Here, we present the first evaluation ...

The aim of the present study was to compare radiotherapy treatment plans for gastric cancer using intensity-modulated radiotherapy (IMRT) and single/double-arc volumetric modulated arc therapy (SA/DA-VMAT) delivery techniques. A total of 29 postoperative gastric cancer patients were enrolled in this study and each patient was scheduled 5-field IMRT (5F-IMRT), 7-field IMRT (7F-IMRT), SA-VMAT and...

OBJECTIVE BMSC (Bone marrow mesenchymal stem cells) is an important seed cell for the repair of bone and cartilage defect in the tissue engineering. The proliferation rate and differentiation capacity of BMSCs from the old donors were less than that from young donors; however, the related mechanism remained unclear. MATERIALS AND METHODS Sprague Dawley (SD) rats BMSCs were cultured and treate...

This study examined whether 15–hr and 24–hr urinary catecholamine measures show comparable associations with other physiological measures that are expected to correlate with sympathetic nervous system activity. Participants (193 healthy adults) provided 24– hr urine samples that were collected in a controlled environment (hotel), and divided into 9–hr daytime and 15–hr overnight collections. On...

Milliken-Taylor systems are some of the most general infinitary configurations that are known to be partition regular. These are sets of the form MT (〈ai〉i=1, 〈xn〉n=1) = { ∑m i=1 ai ∑ t∈Fi xt : F1, F2, . . . , Fm are increasing finite nonempty subsets of N}, where a1, a2, . . . , am ∈ Z with am > 0 and 〈xn〉n=1 is a sequence in N. That is, if p(y1, y2, . . . , ym) = ∑m i=1 aiyi is a given linear...
